Objectives: To assess opioid use during a 6 year period (2001–2006) among cancer patients served by Clalit Health Services, the largest health management organization in Israel.

Methods: Purchasing data of opioids authorized for use in Israel were obtained from the computerized databases of Clalit for the period 2001–2006. Patients' demographic and cancer morbidity data were extracted. The data were analyzed by translating the purchased opioids (fentanyl patch, oxycodone, buprenorphine, methadone, hydromorphone) to oral morphine equivalents (OME).

Results: During the study period 182,066 Clalit members were diagnosed with cancer; 58,443 (32.1%) of them died and 31,628 (17.3%) purchased opioids at least once. In 2001, 7.5% of Clalit cancer patients purchased opioids at least once within 5 years of the initial diagnosis. Between 2002 and 2006 this percentage increased consistently, reaching 9.9% in 2006. The average daily dose of opioids increased from 104.1 mg OME in the year 2001 to 115.2 mg OME in 2006 (11% increase). The average duration of opioid purchasing was 5.0 ± 8.3 months (range 1–84 months, median 2). During the study period 19,426 cancer patients who purchased opioids at least once died; only 14.3% (3274) were still alive 2 years after their first opioid prescription.

Conclusions: Opioid purchasing increased during the study period, especially during the final months of life. Children (0–18 years old) and elderly male patients (≥ 65 years) began opioid treatment later compared to other age groups. Only a few patients had an opioid early enough to relieve their pain. 

Objectives: To assess the prevalence of mental disorders in Israeli youth including tic disorders, as part of the Israel Survey of Mental Health among Adolescents (ISMEHA).

Methods: The ISMEHA was conducted in a representative sample of 957 adolescents aged 14–17 and their mothers during 2004–2005. We interviewed the adolescents and their mothers in their homes and collected demographic information about the use of services. We also administered a psychiatric interview, the Development and Well-Being Assessment inventory (DAWBA), which included a question on tic disorder. The prevalence of tic disorders was calculated based on the adolescents’ and maternal reports. The relationships among demographic data, comorbidity rates, help-seeking behaviors and tic disorder are presented.

Results: The prevalence of tics was 1.3% according to maternal reports and 4.4% according to adolescents’ reports. The prevalence correlated with externalizing disorders and learning disabilities A higher prevalence of tics was found in the Arab population compared with Jewish adolescents

Conclusions: The prevalence of tic disorders in Israel, as measured by a direct question in this epidemiological study, and associated comorbidities concurs with previous reports. The complexities of prevalence estimations, comorbidities, demographic correlates, and help-seeking behaviors are discussed.

Background: Pediatric functional visual loss (FVL) is the loss of vision in a child that cannot be explained by an organic pathology. In the last decade, only a few studies on pediatric FVL have reported long-term patient follow-up.

Objectives: To report the characteristics of pediatric FVL with long-term follow-up in Israeli children.

Methods: We conducted a retrospective chart review of the medical records of patients with FVL from 2000 to 2010. Only children with adequate follow-up (at least 2 months) were included.

Results: Of the 12 patients identified, 9 were females. Mean patient age was 10.5 ± 4.4 years (range 3.5–17 years). Most children (75%) had bilateral visual loss. One patient had a history of psychiatric illness and in three patients a preceding psychosocial event/trauma was identified. Brain imaging and electrophysiology testing (if done) were normal in all cases. No medications were prescribed to any of the patients, and all were reassured that there was a high chance of spontaneous resolution. The follow-up time was 2–108 months (mean 23.8 months, median 6). During the follow-up period 9 of the 12 had complete resolution and 2 had relief of symptoms. Three patients reported a recurrence of symptoms. No organic disease was ever diagnosed in this group.

Conclusions: FVL may occur in all age groups, including children. In cases of visual loss, it is usually bilateral and can involve both acuity and visual field loss. In the present report most of the patients experienced normalization or relief of their symptoms without medical treatment.
 

Background: An outbreak of respiratory illness caused by a novel swine-origin influenza virus (influenza A/H1N1 2009) that began in Mexico was declared a global pandemic by the World Health Organization in June 2009. The pandemic affected many countries, including Israel.

Objectives: To compare the course of chest radiographic and computed tomography findings in patients who survived and those who died following admission to the intensive care unit (ICU) or intubation due to severe laboratory-confirmed swine-origin influenza A/H1N1 2009.

Methods: We retrospectively reviewed the patient records (267 radiographs, 8 CTs) of 22 patients (10 males, 12 females) aged 3.5–66 years (median 34) with confirmed influenza A/H1N1 2009, admitted to the ICU and/or intubated in five major Israeli medical centers during the period July–November 2009. We recorded demographic, clinical, and imaging findings –including pattern of opacification, extent, laterality, distribution, zone of findings, and presence/absence of nodular opacities– at initial radiography and during the course of disease, and compared the findings of survivors and non-survivors. Statistical significance was calculated using the Wilcoxon (continuous variables) and Fisher's exact tests (categorical variables).

Results: The most common findings on the initial chest radiography were airspace opacities, which were multifocal in 17patients (77%) and bilateral in 16 (73%), in the lower or lower and middle lung zones in 19 patients (86%). Large airspace nodules with indistinct margins were seen in 8 patients (36%). Twelve patients survived, 10 died. Patients who died had multiple background illnesses and were significantly older than survivors (P = 0.006). Radiologic findings for the two groups were not significantly different.

Conclusion: Airspace opacities, often with nodular appearance, were the most common findings among patients with severeinfluenza A/H1N1 2009. The course of radiologic findings was similar in patients with severe influenza A/H1N1 2009 whosurvived and those who died.

Background: Staphylococcus aureus infection is a major cause of morbidity and mortality worldwide. Clindamycin is widely used in the treatment of staphylococcal infections; however, it is our impression that in the last few years, inducible clindamycin resistance (ICR) has become more prevalent.

Objective: To assess the prevalence of ICR[1] in methicillin-sensitive Staphylococcus aureus (MSSA) infections among pediatric patients in Israel.

Methods: We reviewed the files of children diagnosed with MSSA[2] infections during the period January 2006 to June 2007 for full antibiogram (including the D-test for ICR), phage typing and randomly amplified polymorphic DNA.

Results: Altogether, 240 MSSA isolates were recovered, mainly from wounds and abscesses. ICR was detected in 62 of 68 erythromycin-resistant/clindamycin-sensitive strains (91%); the ICR rate for the total number of isolates was 26% (62/240). Phage type analysis demonstrated that 38 of 61 ICR isolates

(62%) were sensitive to group 2, compared to 42 of 172 isolates (24%) that did not express ICR (P < 0.01). On randomly amplified polymorphic DNA, phage type 2 isolates expressing ICR belonged to the same clone, which was different from ICR isolates sensitive to other phages and from isolates not expressing ICR.

Conclusions: Inducible clindamycin resistance is common among methicillin-sensitive Staphylococcus aureus in Israeli children. The D-test should be performed routinely in all isolates of MSSA.

Background: The majority of human brucellosis cases in Israel are caused by the ingestion of unpasteurized dairy foods produced from unlicensed family-owned flocks whose products are sold door-to-door at low prices. Exposure to infected farm animals is another major cause of infection.

Objectives: To determine, by examining recent incidence data and brucellosis control programs, whether a reduction in the incidence of human brucellosis in Israel can be sustained.

Methods: Case information is reported to the Health Ministry and national data are compiled and analyzed by the Division of Epidemiology. The current study focuses on data from 1998 through 2009 and discusses several of the major prevention and health education programs that have been implemented.

Results: An incidence decline of almost 70% during the period 1998–2002 was followed by a return to previously existing levels, although the incidence has remained consistently lower than in past decades. The disease is mostly limited to certain sectors of the rural Arab population. In 2009 the incidence rate per 100,000 population was 7.0 among Arabs compared with 0.2 among Jews. Between 1998 and 2009, 63% of cases were from the Beer Sheva and Acre health districts, which together comprise 15.5% of the Israeli population. Control programs - including efforts to combat brucellosis in animals and to discourage the sale of unpasteurized homemade dairy products - have met with partial success.

Conclusions: Without routine vaccination of all family-owned flocks, more effective restraints on the market for unpasteurized dairy foods and improved regional cooperation, human brucellosis will continue to be a contained, but persistent, health problem in Israel due to cultural behavior, socioeconomic factors, and the regional political environment.
 

Immunization coverage is a major health indicator. In Israel, routine childhood immunizations are provided at community public well-baby clinics. Immunization monitoring is an important cornerstone of a national health policy however, data obtained through sampling carries the risk of under-representation of certain population strata, particularly high risk groups. Despite high national average immunization coverage, specific sub-populations are under-immunized, as highlighted by outbreaks of vaccine-preventable diseases. The mean national immunization coverage at age 2 years (2006 data) was: DTaP[1]-IPV[2]-Hib4[3] (all 93%), HBV[4]3 (96%), MMR1[5] (94%), HAV1[6] (90%). These reports are based on a 17% population-based sample in some districts and on cumulative reports in others. A national immunization registry requires data completeness, protection of confidentiality, compulsory reporting by providers, and links to other computerized health records. It should provide individual immunization data from infancy to adulthood and be accessible to both providers and consumers. In 2008 the Israel Ministry of Health launched a national immunization registry based on immunization reporting from well-baby clinics using a web-based computerized system. As of January 2010, 120 well-baby clinics are connected to the nascent registry, which includes the records of some 50,000 children. The implementation of a comprehensive national immunization registry augurs well for the prospect of evidence-based assessment of the health status of children in Israel.

Background: In the last decade the diagnosis of celiac disease has increasingly been made in adults.

Objectives: To determine disease prevalence (including silent and potential disease) in this population group.

Methods: We performed serologic screening of celiac disease in a representative and homogenous sample of a young adult general population in Israel, namely, 18 year old military conscripts, in 2003. Serologic screening was performed on serum samples randomly obtained from 850 healthy recruits (male/female = 1.1). Immunoglobulin A anti-tissue transglutaminase was determined by enzyme-linked immunosorbent assay. In cases of IgA[1] deficiency, IgG anti-endomysial antibodies were determined. A small intestinal biopsy was offered to all patients with positive serology.

Results: The prevalence of overt CD[2] diagnosed prior to recruitment was 0.12% (0.1% in men and 0.14% in women). The overall prevalence based on positive serology was 1.1%. Six of nine subjects with positive serology agreed to undergo endoscopy and intestinal biopsies. In all cases, biopsies were compatible with celiac disease (five biopsies were graded as Marsh 3a and one as Marsh 3b). One subject previously reporting irritable bowel-like symptoms was diagnosed with overt atypical CD. The prevalence of overt CD diagnosed by screening was 0.12%. The ratio of overt to silent CD was 1:8. No cases of potential disease were encountered.

Conclusions: Our findings suggest that CD is highly prevalent in the young adult population in Israel. Serologic screening for CD is a reliable and simple method for diagnosing this disease before symptoms or complications develop.

Background: Autoimmune neutropenia of infancy is caused by neutrophil-specific autoantibodies. Primary AIN[1] is characterized by neutrophil count < 500 ml and a benign self-limiting course. Detecting specific antibodies against the polymorphic human neutrophil antigen usually confirms the diagnosis. Current available tests, however, are expensive and inapplicable in many laboratories as they require the use of isolated and fixed granulocytes obtained from donors pretyped for their distinct HNA[2] alloform.

Objectives: To assess the performance of a modified test to identify by FACS-analysis granulocyte-specific antibodies in the sera of neutropenic children.

Methods: We evaluated 120 children with a clinical suspicion of AIN, whose sera were analyzed by flow cytometry for the presence of autoantibodies using the indirect granulocyte immunofluorescence test. In contrast to the traditional tests, the sera were tested against randomly selected untyped neutrophils derived from a batch of 10 anonymous healthy subjects, presumably including the common HNA alloforms. Control sera samples were from patients with chemotherapy-induced, familial or congenital neutropenias. To further assure the quality of the new test, we retested six samples previously tested by the gold standard method. All medical files were screened and clinical outcomes were recorded.

Results: Our method showed specificity of 85%, sensitivity of 62.5%, and a positive predictive value of 91.8%, values quite similar to those obtained by more traditional methods.

Conclusions: The new method showed high specificity for detection of anti-neutrophil antibodies in the appropriate clinical setting and could be an effective aiding tool for clinical decision making.
