Background: The Israel National Poison Information Center, Rambam Health Care Campus, provides telephone consultations on clinical toxicology as well as drug and teratogen information around the clock. The Center participates in research, teaching and regulatory activities, and also provides laboratory services.
Objectives: To analyze data on the epidemiology of poisonings and poison exposures in Israel.
Methods: We conducted computerized queries and a descriptive analysis of the medical records database of the IPIC during 2007.
Results: Overall, 26,738 poison exposure cases were recorded, a 118.5% increase compared to 1995. Children under 6 years old were involved in 45% of cases; 73% of the calls were made by the public and 25.5% by physicians; 74.4% of exposures were unintentional and 9.2% intentional. Chemicals were involved in 37.9% of cases, pharmaceuticals in 44.2%, bites and stings in 4.3% and poisonous plants in 1.2%. Substances most frequently involved were analgesics, cleaning products and antimicrobials. Clinical severity was moderate/major in 3.5%. Substances most frequently involved in moderate/major exposures were insecticides, drugs of abuse and corrosives. Eight fatalities were recorded – three unintentional exposures (all chemicals) and five intentional (chemicals, medications, drugs of abuse).
Conclusions: The rates of poison exposures and poisonings in Israel have increased significantly, contributing substantially to morbidity and mortality. The IPIC database is a valuable national resource for collecting and monitoring cases of poison exposure and can be used as a real-time surveillance system. It is recommended that reporting to the IPIC become mandatory and that its activities be adequately supported by national resources.

Background: The Palestinian Poison Control and Drug Information Center was established in 2006 to provide up-to-date information on medications and to help in the early diagnosis and management of poisoning cases.
Objectives: To summarize the activities carried out by the PCDIC in the past 2 years.
Methods: Documented inquires received at the PCDIC were analyzed and the Center's activities were extracted from the files.
Results: During the first 2 years of the Center's existence, 323 inquiries were received, mainly (67.2%) from physicians; 70% of the calls were from the city of Nablus. Unintentional poisoning was the leading type of call (62.8%) followed by suicidal poisoning (20.7%). Medications were the major category of toxicants encountered (48.9%), followed by pesticides (23.5%). In 67.9% of the cases, the calls were initiated before any treatment was provided. The advice provided by the PCDIC was based on the nature of the call. During these 2 years the PCDIC has conducted several academic and non-academic activities. The Center introduced the concept of poison prevention weeks in Palestine and has conducted two so far. The PCDIC has published several articles in the fields of toxicology, rational drug use, complementary and herbal therapy, pharmacoepidemiology, and self-medication.
Conclusions: Documentation of all inquiries is mandatory for analysis, evaluation, comparative purposes, and quality assurance. More information campaigns are needed to encourage people to use the services provided by the PCDIC.

The relative accessibility to various chemical agents, including chemical warfare agents and toxic industrial compounds, places a toxicological mass casualty event, including chemical terrorism, among the major threats to homeland security. TMCE represents a medical and logistic challenge with potential hazardous exposure of first-response teams. In addition, TMCE poses substantial psychological and economical impact. We have created a simple response algorithm that provides practical guidelines for participating forces in TMCE. Emphasis is placed on the role of first responders, highlighting the importance of early recognition of the event as a TMCE, informing the command and control centers, and application of appropriate self-protection. The medical identification of the toxidrome is of utmost importance as it may dictate radically different approaches and life-saving modalities. Our proposed emergency management of TMCE values the “Scoop & Run” approach orchestrated by an organized evacuation plan rather than on-site decontamination. Finally, continuous preparedness of health systems – exemplified by periodic CBRN (Chemical, Biological, Radio-Nuclear) medical training of both first responders and hospital staff, mandatory placement of antidotal auto-injectors in all ambulances and CBRN emergency kits in the emergency departments – would considerably improve the emergency medical response to TMCE.

Organophosphate and carbamate are mainly used to kill insects, thereby protecting livestock, crops, homes and communities. Yet, these compounds also convey great danger. OP and CRB poisoning is an important clinical problem, often life-threatening, especially in the pediatric population in rural areas where reaching a physician or hospital on time is difficult. We present a summary of accumulated toxicological knowledge as well as clinical and laboratory experience from a medical center serving a relatively vast rural area and pediatric population. We stress the importance of knowing how to recognize the classic signs of OP and CRB poisoning and when it is appropriate to investigate for such poisoning even in the absence of those signs. Like any medical emergency, OP and CRB poisoning requires prompt resuscitation and use of antidotes. Atropine, oxygen and fluids are the mainstay of therapy. Oximes, which were found useful in some cases of OP poisoning and useless in some cases of CRB poisoning, are absolutely safe as empiric treatment, which is often needed since the major differential diagnosis of OP poisoning is CRB poisoning that is clinically indistinguishable. We hope that continuing research will offer further insights into the management of such events, and we are confident that improved medical management of OP and CRB poisoning will result in a reduction of morbidity and other complications associated with intensive care procedures and hospitalization.

Background: Medication errors are a common cause of morbidity and mortality.
Objectives: To evaluate the rate of acknowledgment of medication errors as reported by physicians working in the community and in hospitals.
Methods: An anonymous questionnaire was sent to 9320 active physicians (about 48% community physicians, 17% hospital physicians and 35% working in both places), with questions on the rate and type of medication errors that they had encountered during their professional career. The questions specified errors in dosage, type of medicine (wrong indication), route of administration and drug interactions.
Results: Only 627 physicians (6.7%) responded. Of these, nearly 79% admitted having made an error in prescribing medication; the majority admitted to more than one error. Physicians with fewer years of experience admitted having made a mistake more than did physicians with more experience (P = 0.019). Pediatricians and geriatricians made more dosage mistakes (P = 0.02), while family physicians and psychiatrists made more mistakes in drug interactions (P = 0.001).
Conclusions: It is possible that indifference, fear of identification, or lack of awareness may have contributed to the low response rate despite the fact that the questionnaire was anonymous. Educational programs should be implemented in medical schools to encourage physicians to report errors before the onset of adverse reactions.

Background: Infections with blood-borne viruses are a major health problem among illicit drug users. There is little information about infection rates and risk factors for hepatitis virus B, C or the human immunodeficiency virus in drug users in Israel.
Objectives: To determine the prevalence of HCV, HBV and HIV infections in a large cohort of drug users in Israel; to compare rates of HCV, HBV and HIV between injecting versus non-injecting drug users and between different origin countries; and to identify risk factors for HCV among illicit drug users.
Methods: We conducted a cross-sectional interviewer-administered questionnaire and serological screening for HCV, HBV and HIV in 1443 consecutive drug users diagnosed at the Israeli National Center for Diagnosis of Drug Addicts between January 2003 and December 2005.
Results: Fourteen (0.9%), 51 (3.5%) and 515 (35.7%) subjects tested positive for HIV, HBV and HCV, respectively. All three infections (HIV, HBV and HCV) were significantly more common among injecting drug users and immigrants from the former Soviet Union and other East European countries compared to native Israelis. Multivariate analysis showed that HCV infection was associated with age (> 40 years) (OR=2.06, 95% CI 1.40–3.03), immigration from East European countries and the former Soviet Union (OR=4.54, 95% CI 3.28–6.28), and injecting drug use (OR=16.44, 95% CI 10.79–25.05).
Conclusions: HIV, HBV and HCV prevalence among drug users in Israel is significantly lower than in North America and West Europe. Risk factors for HCV infection in this population include injecting drug use, older age, and immigration from the former Soviet Union.

Background: Clinicians’ impression of adolescents' alcohol or drug involvement may underestimate substance-related pathology.
Objectives: To describe the characteristics of adolescents presenting to the pediatric emergency department due to substance abuse and to determine whether physicians can reliably identify these patients.
Methods: We conducted a prospective cohort study of all patients aged 12–18 years presenting to a pediatric emergency department between 1 January 2005 and 31 December 2006 for whom a urine drug screen or ethanol blood levels was ordered. According to departmental protocol urine drug screen and ethanol levels are taken for specific indications. Based on the history and clinical findings the pediatrician in the ED assessed on a 5-point likelihood scale the possibility that the patients’ symptoms were related to substance abuse.
Results: Of the 139 patients in the study group 40 (30%) tested positive for ethanol or drugs of abuse. The median age was 16. Compared with patients who tested negative, there were more patients with decreased level of consciousness among patients who tested positive for ethanol or drugs (5% vs. 33% respectively, P < 0.001). The median physician estimate for the likelihood of substance abuse was 5 in patients who tested positive and 2 in patients who tested negative (P < 0.001). The likelihood of a positive drug/ethanol test was not affected by age or gender.
Conclusions: Since the likelihood of substance abuse is higher in patients presenting with a low level of consciousness, physicians may accurately assess the likelihood of substance abuse in these patients
