The courts have recently become increasingly involved in the administration of compulsory psychiatric services in Israel. Data reveal a gradual increase in the rate of court-ordered hospitalizations according to Section 15 of the Law for the Treatment of the Mentally Ill. This paper examines the implications of this trend, particularly the issues of security and safety in psychiatric hospitalization. We present highlights from extensive British experience, focusing on the implications on forensic psychiatry in Israel. We review the development of the hierarchy of security in the British psychiatric services, beginning in the early 1970s with the establishment of the Butler Committee that determined a hierarchy of three levels of security for the treatment of patients, culminating with the establishment of principles for the operation of medium security units in Britain (Read Committee, 1991). These developments were the basis for the forensic psychiatric services in Britain. We discuss the relevance of the British experience to the situation in Israel while examining the current status of mental health facilities in Israel. In our opinion, a safe and suitable environment is a necessary condition for a treatment setting. The establishment of medium security units or forensic psychiatry departments within a mental health facility will enable the concentration and classification of court-ordered admissions and will enable systemic flexibility and capacity for better treatment, commensurate with patient needs.

Background: While family presence during resuscination has been researched extensively in the international and especially American medical literature, in Israel this subject has rarely been researched. Because such policies have become common practice in many countries, it is important to investigate the attitudes of health care staff in Israeli emergency departments to better understand the potential implication of adopting such policies.

Objectives: To examine the attitudes of the physicians and nurses in the ED of Soroka Medical Center to FPDR[1]. 

Methods: The methods we used were both qualitative (partly structured open interviews of 10 ED staff members from various medical professions) and quantitative (an anonymous questionnaire that collected sociodemographic, professional, and attitude data).

Results: The qualitative and quantitative results showed that most staff members opposed FPDR. The main reasons for objecting to FPDR were concern about family criticism, the added pressure that would be put on the staff members, fear of lawsuits, fear of hurting the feelings of the families, and the danger of losing one’s objectivity while treating patients. Physicians objected more strongly to FPDR than did nurses.  

Conclusions: More research is needed on FPDR in Israel, including an examination of its medical, ethical, legal and logistic aspects. In addition to the views of the medical staff, the attitudes of patients and their families should also be examined.

Background: The incidence of stroke varies among ethnically and culturally diverse groups.

Objectives: To examine the ethnic-geographic patterns of stroke incidence in men and women with coronary heart disease in Israel, focusing on the extent to which this variability can be explained by known differences in risk factors for stroke.

Methods: Patients with documented coronary heart disease were followed for 6–8 years for incident cerebrovascular events. Baseline medical evaluation included assessment of vascular risk factors and measures of blood lipids. Among 15,052 patients, a total of 1110 were identified with any incident ischemic cerebrovascular event by ICD-9 codes, of whom 613 had confirmed ischemic stroke or transient ischemic attack.

Results: A major excess of ischemic cerebrovascular events among Israeli Arab women as compared to males, and an inverse finding among Israeli born Jews, were noted. The high risk in the Arab population in Israel reflected an unfavorable risk profile, since predicted rates by multivariate analysis and observed rates were 69 and 68 per 1000, respectively. High ischemic cerebrovascular event rates were identified among patients born in the Balkan countries and North Africa (89 and 90 per 1000) but unfavorable risk factor levels of these individuals did not explain them. Most trends appeared similar in male and female patients. A comparison of observed and accepted-according-to-risk-profile rates of ischemic cerebrovascular events yielded significant differences (P = 0.04), consistent with an additional role of geographic/ethnic origin, resulting from factors that remain unrecognized,or with variables unassessed in this study.

Conclusions: We identified an ethnic diversity in stroke risk among Israeli born in different parts of the world beyond what could be expected on the basis of differences in known risk factors. These findings call for detailed research aimed at identifying additional differences in the risk profile of patients with atherothrombotic disease exposed to an increased risk of stroke.
 

Background: Chronic heart failure is associated with excessive hospitalizations and poor prognosis.

Objectives: To summarize the 5 year experience of a single-center CHF[1] day care service, detect the cardiovascular and non-cardiovascular events, and evaluate the safety of the treatments provided.

Methods: We retrospectively studied all patients admitted to the CHF day care service of the Sheba Medical Center between September 2000 and September 2005.

Results: Advanced (New York Heart Association class III-IV) CHF patients (n=190), mean age 65 ± 12 years and left ventricular ejection fraction 25 ± 11%, were treated for 6 hourly biweekly visits; 77% had ischemic and 23% had non-ischemic cardiomyopathy. Treatment included: intravenous diuretic combinations (91%), intermittent low dose (≤ 5 mg/kg/min) dobutamine (87%), low dose (≤ 3 mg/kg/min) dopamine (38%), intravenous iron preparation and/or blood (47%), and intravenous nitropruside (36%). Follow-up of at least 1 year from initiation of therapy was completed in 158 of 190 patients (83%). Forty-six (29.3%) died: 23% due to CHF exacerbation, 5.7% from infection, 4.4% from sudden cardiac death, 3.8% from malignancy, 2.5% from malignant arrhythmias, 1.9% from renal failure, 1.3% from stroke, and 0.6% from myocardial infarction. There were only 0.68 rehospitalizations/patient/year; the most frequent cause being CHF exacerbation (16.5%).

Conclusions: Our study demonstrates the safety and potential benefits of a supportive day care service for advanced CHF patients. Multidrug intravenous treatment, accompanied by monitoring of electrolytes, hemoglobin and cardiac rhythm, along with education and psychological support, appear to reduce morbidity in advanced CHF patients and may have contributed to the lower than expected mortality/hospitalization rate.

Background: Sickle cell anemia is a hemolytic anemia caused by a single mutation in position 6 of the β globin molecule. About 80 patients with SCA[1] in northern Israel are currently receiving treatment.

Objectives: To assess a screening program in northern Israel aimed at detecting couples at risk for having offspring with SCA.

Methods: Since 1987, screening for β thalassemia in pregnant women in northern Israel has been conducted, and from 1999 all the samples were also tested for hemoglobin S, Hgb C, Hgb D, Hgb O Arab and others.

Results: During the 20 year period 1987–2006 a total of 69,340 women were screened; 114 couples who carried Hgb S were detected and 187 prenatal diagnoses were performed in couples at risk for having an offspring with Hgb S. The mean gestational age was 13 ± 4 weeks. Fifty-four of those diagnoses revealed affected fetuses and in 4 cases the couple declined to perform therapeutic abortion.

Conclusions: The economic burden to the health services for treating SCA patients is about U.S.$ 7000 per year, and the institution of prevention programs has proven cost-effective in populations with a high frequency of carriers. Since our program is aimed to also detect β thalassemia, a disease that is more frequent in this area (> 2.5%), the added cost for the prevention of SCA is less significant in spite a low incidence of the S gene in our population, namely < 1%.

Hereditary angioedema is a rare genetic disorder, manifested by recurrent edema leading to disfigurement, organ dysfunction and life-threatening respiratory impairment that may become fatal. The hallmark of HAE is a C1 esterase inhibitor deficiency, but recent evidence points at bradykinin as the main mediator that causes hyperpermeability of small vasculature, leading to accumulation of edema fluid. Current therapeutic options for HAE[1] are limited, and consist of drugs, replacement therapy, and supportive treatment. In view of many disadvantages of the current therapeutic modalities new approaches to the treatment of HAE are now being offered. This review summarizes our experience with a new line of medications developed for the treatment of acute exacerbations and prophylaxis of HAE – icatibant: bradykinin receptor antagonist, ecallantide: kallikrein inhibitor, and two C1 INH[2] preparations: Berinert-P, human plasma-derived concentrate, and Rhucin: novel recombinant C1-INH produced in transgenic rabbits. Preliminary results of these studies are encouraging and may bring new hope to the patients with this distressing condition. The exact number of HAE patients in Israel is unknown and because patients are treated individually and comprehensive laboratory assessment is partial, many cases might be missed or not treated according to accepted guidelines. We offer a new specialty center for HAE patients, addressing the medical and psychosocial needs of patients and their families.

Background: The C677T mutation in the methylenetetrahydrofolate reductase (MTHFR) gene is associated with early onset of coronary artery disease in some populations with certain ethnic backgrounds. However, data on its effect on CAD[1] development in women are limited and conflicting.

Objectives: To investigate the effects of the MTHFR C677T mutation and ethnicity on the development and age at onset of CAD in women in Israel.

Methods: The sample included 135 Jewish women with well-documented CAD (62 Ashkenazi, 44 Oriental and 29 of other origins) in whom CAD symptoms first developed at age ≤ 65 years. DNA samples from 235 women served as the control.

Results: CAD symptoms developed later in Ashkenazi than in Oriental women or women of other origins (51.0 ± 7.0 years vs. 48.3 ± 7.5 and 46.3 ± 7.7 years, respectively, P = 0.024). Among Ashkenazi women, the T/T genotype was less common in patients in whom CAD symptoms appeared after age 50 (6.4%) than in patients with earlier CAD symptoms (25.8%, P = 0.037) and Ashkenazi control subjects (23.3%, P = 0.045). Among women from other origins, these differences were not significant. On logistic regression analysis, the T/T genotype was associated with a nearly fourfold increase in the risk of early onset (age < 50 years) of CAD (odds ratio 3.87, 95% confidence interval 1.12–13.45, adjusted for risk factors and origin) and a trend towards an influence of ethnicity (P = 0.08). Compared to Ashkenazi women, the risk of early development of CAD associated with the T/T genotype among Oriental ones was 0.46 (95%CI[2] 0.189–1.114) and in women of other origins, 5.84 (95%CI 1.76–19.34). Each additional risk factor increased the risk of earlier onset of CAD by 42% (OR[3] 1.42, 95%CI 1.06–1.89).

Conclusions: The age at onset of CAD in Israeli women is influenced by the MTHFR genotype, ethnic origin and coronary risk factors.

Background: Reports of burn injuries in children are usually made by highly specialized burn units. Our facility admits children with burns < 20% total body surface area, while those with major burns are transferred to burn units at tertiary care facilities.

Objectives: To review our experience with thermal burns.

Methods: We conducted a retrospective review of all thermal burns admitted to our hospital during a 5 year period.

Results: Among 266 patients (69.2% boys) aged 3.5 ± 3.6 years, children < 3 years old were the most frequently injured (64.7%). Scalds (71.4%) were the most common type of burn. Partial thickness burns were sustained by 96.6% of children and TBSA[1] burned was 4.2 ± 3.6%. The mean hospital stay was 3.8 ± 4.5 days, and was significantly prolonged in girls (4.6 ± 4.8 vs. 3.5 ± 4.3 days, P = 0.01). Percent TBSA burned was correlated with patient age (r = 0.12, P = 0.04) and length of hospital stay (r = 0.6, P < 0.0001). Six patients (2.3%) (mean age 3.4 ± 2.3 years) were hospitalized in the Pediatric Intensive Care Unit due to toxin-mediated illness.

Conclusions: Children under the age of 3 years are at increased risk for burn injury, but older children sustain more extensive injuries. Prevention and awareness are needed for child safety.

Background: Iron deficiency and lead poisoning are common and are often associated. This association has been suggested previously, mainly by retrospective cross-sectional studies.

Objective: To assess the impact of short-term lead exposure at indoor firing ranges, and its relationship to iron, ferritin, lead, zinc protoporphyrin, and hemoglobin concentrations in young adults.

Methods: We conducted a clinical study in 30 young healthy soldiers serving in the Israel Defense Forces. Blood samples were drawn for lead, zinc protoporphyrin, iron, hemoglobin and ferritin prior to and after a 6 week period of intensive target practice in indoor firing ranges.

Results: After a 6 week period of exposure to lead dust, a mean blood lead level increase (P < 0.0001) and a mean iron (P < 0.0005) and mean ferritin (P < 0.0625) decrease occurred simultaneously. We found a trend for inverse correlation between pre-exposure low ferritin levels and post-exposure high blood lead levels.

Conclusions: The decrease in iron and ferritin levels after short-term lead exposure can be attributed to competition between iron and lead absorption via divalent metal transport 1, suggesting that lead poisoning can cause iron depletion and that iron depletion can aggravate lead poisoning. This synergistic effect should come readily to every physician's mind when treating patients with a potential risk for each problem separately.
 

Background: Early detection of malignant melanoma of the skin is the most important factor in patient survival. Naked-eye diagnostic sensitivity and specificity are low. Patients with multiple nevi are at high risk to develop melanomas and the clinical follow-up of such patients is difficult, resulting in missed melanomas on the one hand and unnecessary biopsies on the other.

Objectives: To describe the set-up of a special clinic aimed at early detection of melanoma and follow-up of high risk patients and preliminary results from 20 months of operation.

Methods: We established a pigmented lesions clinic based on a digital photography studio enabling documentation and comparison over time of full body photography and dermoscopy.

Results: In the first 20 months of work, 895 patients were seen, 206 of them for follow-up visits. A total of 29,254 photos were taken. Altogether, 236 lesions were suspicious (either clinically or dermoscopically) and the patients were advised to excise them. Seven melanomas were found in this initial examination (which did not include long-term follow-up).

Conclusions: With multimode photographic cutaneous surveillance, early detection of melanoma in high risk patients has been reported. Our clinic utilizes the same techniques and diagnostic algorithm as other leading clinics throughout the world, thus enabling us to deliver better follow-up for those patients.
