Background: Sentinel lymph node mapping is the standard of care for patients with malignant melanoma and breast cancer. Recently, SLN[1] mapping was introduced to the field of gastric cancer.

Objectives: To evaluate SLN mapping in patients with gastric cancer.

Methods: In 43 patients with gastric cancer, open intraoperative subserosal dye injection in four opposing peritumoral points was used. Ten minutes following dye injection, stained LNs were located, marked and examined postoperatively from the surgical specimen.

Results: SLN mapping was performed in 43 with gastric cancer; 782 lymph nodes were harvested and evaluated. SLNs were stained in 34 of the patients (79.1%) with a mean of 2.85 SLNs per patient. The false negative rate was 20.9%, the positive predictive value 100%, the negative predictive value 78.6% and the sensitivity 86.9%.

Conclusions: SLN mapping in patients with gastric cancer is feasible and easy to perform. SLN mapping may mainly affect the extent of lymph node dissection, and to a lesser degree gastric resection. However, more data are needed.

Background: In Japan, helicopters have rarely been used for emergency medical services. The use of helicopters not only ensures rapid evacuation but may also serve to provide emergency management to patients with life-threatening injuries in the prehospital setting.

Objectives: To evaluate a Japanese helicopter-based emergency medical system including an onboard physician, particularly in terms of probability of survival.

Methods: We conducted a retrospective review of trauma victims, and calculated two estimates of PS[1] – at the scene and on arrival at the emergency department – based on patient age, Injury Severity Score, and Revised Trauma Score.

Results: We identified trauma victims who had an ISS[2] above 15 and were transported from the scene by helicopter. Excluding cardiopulmonary arrest at the scene, 151 cases were studied. Thirty-two patients had hemodynamic instability with systolic blood pressures below 90 mmHg, caused by hemorrhagic shock (29 cases) or obstructive shock (3 cases). Their PS values were 0.56 ± 0.38 in the prehospital setting and 0.65 ± 0.38 on arrival at the ED[3], representing a significant difference (P = 0.0003). Twenty-four of these patients survived, reflecting successful resuscitation during prehospital and ED management.

Conclusions: A doctor-helicopter system was shown to improve probability of survival for life-threatening trauma in the Japanese emergency medical system.

Background: There are no national data on the burden and management of acute cerebrovascular disease in Israel.

Objectives: To delineate the burden, characteristics, management and outcomes of hospitalized patients with acute cerebrovascular disease in Israel, and to examine adherence to current guidelines.

Methods: We prospectively performed a national survey in all 28 hospitals in Israel admitting patients with acute cerebrovascular events (stroke or transient ischemic attacks) during February and March 2004.

Results: During the survey period 2,174 patients were admitted with acute cerebrovascular disease (mean age 71 ± 13 years, 47% women; 89% ischemic stroke or TIA[1], 7% intracerebral hemorrhage and 4% undetermined stroke). Sixty-two percent of patients were admitted to departments of Medicine and a third to Neurology, of which only 7% were admitted to departments with a designated stroke unit. Head computed tomography was performed during hospitalization in 93% of patients. The overall rate of urgent thrombolytic therapy for acute ischemic stroke was 0.5%. Among patients with ischemic stroke or TIA, 94% were prescribed an antithrombotic medication at hospital discharge, and among those with atrial fibrillation about half were prescribed warfarin. Carotid duplex was performed in 30% and any vascular imaging study in 36% of patients with ischemic events. The mean length of hospital stay was 12 ± 27 days for ICH[2] and 8 ± 11 days for ischemic stroke. Among patients with ICH, 28% died and 66% died or had severe disability at hospital discharge, and for ischemic stroke the corresponding rates were 7% and 41% respectively. Mortality rates within 3 months were 34% for ICH and 14% for ischemic stroke.

Conclusions: This national survey demonstrates the high burden of acute stroke in Israel and reveals discordance between existing guidelines and current practice. The findings highlight important areas for which reorganization is imperative for patients afflicted with acute stroke.

Twenty years ago the Israeli Association of Allergy and Clinical Immunology was established, unifying these two fields into one speciality.

The autoimmune lymphoproliferative syndrome is a recently described human disorder that affects lymphocyte programmed cell death (apoptosis).

Intravenous immunoglobulins have been used as therapeutic proteins since the early 1980s.

Although the airway granulomata in Wegener's granulomatosis were stressed initially by Friedrich Wegener himself, in the last few decades systemic lesions mainly caused by acute vasculitis have received the most attention. However, recently, the implication of granulomatous manifestations in WG[1] has raised much interest. The present data suggest that an aberrant Th1-type response might play a role in the initiation of WG, clinico-pathologically characterized by granulomatous inflammation rather than vasculitis. Disease progression to generalized WG with the predominance of vasculitic manifestations is associated with a “switch” or further complexity of the collective T cell response with the appearance of another subset of Th2-type cells and a less prominent Th1-type cytokine production in the granulomatous lesions of the upper respiratory tract. However, the clinical significance of the granulomatous inflammation is not yet completely understood. Further research will also have to focus on the role of the granulomata during relapsing disease. We review present knowledge of granulomatous inflammation in WG. Morphologic aspects, the scale of cytokine alterations as well as the variety of clinical manifestations are discussed.

Background: Heat shock proteins are highly conserved immunodominant antigens found in various species. Humoral immune responses to mycobacterial HSP65[1] and human HSP60 have been established in a number of human autoimmune diseases.

Objective: To assess the prevalence of antibodies to HSP60 kDa and HSP65 kDa in patients with Sjogren's syndrome as compared to normal subjects.

Methods: Thirty-seven patients with SS[2] were compared with normal controls. The antibodies against human HSP60 were measured by the Anti-Human (IgG/IgM) HSP60 ELISA kit. IgGs[3] and IgMs to mycobacterial HSP65 were determined using an enzyme-linked immunosorbent assay with mycobacterial recombinant HSP65 antigens.

Results: The levels of both anti-HSP60 and -HSP65 were lower among patients compared with controls. IgG autoantibodies to HSP60 were significantly different between groups: 162 ± 55.1 ng/ml in controls versus 112.3 ± 30.6 ng/ml in SS patients (P < 0.001). The levels among controls of anti-HSP65 IgM isotype were also significantly higher than among patients: 111.6 ± 33.4 U/ml versus 96.1 ± 8.9 U/ml (P = 0.01).

Conclusions: The results of the present study show that the levels of different isotypes of anti- HSP60 and HSP65 antibodies were lower in patients with SS than in normal subjects. Additional studies on larger patient populations are required to evaluate the prevalence of these autoantibodies in SS patients.

Background: Dyspnea may be a presenting symptom of type I food hypersensitivity, and bronchial hyper-reactivity, without known asthma, can coexist in patients with food allergy.

Objective: To evaluate airway involvement in young adult patients with food allergy and no asthma and compare the findings to those of patients with food allergy and asthma, with food allergy and allergic rhinitis, with asthma and no food allergy, and of apparently healthy controls.

Methods: The evaluation involved prick skin test to food (65 allergens) and inhalants (24 allergens), spirometry, methacholine inhalation challenge, and induced sputum for cell analysis. The five groups consisted of 18 patients with food allergy alone, 11 with food allergy and asthma, 13 with food allergy and allergic rhinitis, 10 with asthma alone, and 10 controls.

Results: Patients with food allergy alone were mainly (86%) skin sensitive to pollens. Those with either asthma or allergic rhinitis were mainly (95%) sensitive to mites. BHR was detected in 40% of the patients with food allergy alone, 55% of the patients with allergic rhinitis, and 100% of the patients with asthma. Cell counts in the sputum of patients with asthma and in those with food allergy and asthma showed higher eosinophil counts compared to those with food allergy and allergic rhinitis. Patients with food allergy and no asthma, regardless of BHR status, had mainly neutrophils in the sputum.

Conclusions: Patients with food allergy are highly likely to have concomitant asymptomatic BHR. Mite sensitivity in patients with food allergy predicts respiratory allergy (either asthma or allergic rhinitis). High eosinophil levels in the sputum of food allergy patients predict respiratory involvement.

Background: In the last decade there has been an increase in asthma morbidity. Hospital admission rates for childhood asthma are influenced by the prevalence of asthma and the quality of asthma care.

Objective: To assess trends in hospital admission and readmission rates for childhood asthma in the Jezreel Valley in Israel in the last decade, and to evaluate the possible effect of changes in asthma treatment upon hospitalization for acute asthma during this period.

Methods: All records from pediatric patients from the central hospital in the Jezreel Valley in northeastern Israel over a 10 year period from 1990 through 1999 who were diagnosed as having asthma were thoroughly reviewed and analyzed for admissions, re-admissions, and treatment before and during admissions

Results: There were 1584 admissions, 1208 were first-time admissions and 374 were re-admissions. The number of first-time admissions increased significantly over time (P < 0.0001), with a significant decrease of re-admissions (P < 0.005); this finding was more significant in children under the age of 8 years (P < 0.005). The length of hospital stay decreased significantly from 3.3 days to 2.7 days (P < 0.002). Significant changes in the use of medications included an increase in inhalant glucocorticoids and a decrease in the use of sodium cromoglycate and theophylline. Controller medication use was concomitant with a significant decrease in the re-admission rates.

Conclusions: The increase in the admission rate and the decrease in the rate of re-admissions and the length of hospital stay probably reflect the increase in the prevalence of asthma and changes in its treatment, respectively. It is essential that asthma be recognized as a significant cause of morbidity and that controller medications be administered to decrease the asthma's severity, morbidity, and resultant hospital admissions.
 

Non-steroidal anti-inflammatory drugs, mainly ibuprofen, are extensively used in children as analgesics and antipyretics.

Background: Since 1984, several waves of Ethiopian immigrants have settled in Israel. On arrival they were found to be highly infected with intestinal parasites and to have increased serum immunoglobulin E and eosinophilia. 

Objectives: To study serum IgE [1] levels in Ethiopian children growing up in the environment of Israel . 

Methods: We assessed four groups of children of Ethiopian origin: a) adolescents examined on their arrival to Israel (group 1, n=11); b) adolescents born in Ethiopia and living in Israel for more than 7 years (group 2, n=10); c) children of Ethiopian origin born in Israel, without a history of allergy or asthma (group 3, n=15); and d) asthmatic children of Ethiopian origin born in Israel (group 4, n=8). A thorough clinical interview and examination as well as serum IgE levels, stool parasites and absolute eosinophil count were performed. 

Results: Group 1 (11 newly arrived Ethiopian adolescents) had a mean eosinophil count of 688 cells/ml (0–1739) and a mean serum IgE of 1043 IU/ml (253–2932), P < 0.0009 as compared to group 2. Helminthic parasites were observed in 8/11 individuals; after 1 year of follow-up and anti-parasitic treatment, serum IgE levels did not change significantly. Group 2 (10 Ethiopian born adolescents living in Israel for on average 10 years, 7–15 years) had a normal leukocyte count, MEC [2] 192 cells/ml (range 54–289), serum IgE 142 IU/ml (range 14–399 IU/ml) and no parasites in stool. Group 3 (15 Ethiopian children born in Israel) had a normal leukocyte count, MEC 128 cells/ml (0–324), serum IgE 55 IU/ml (7–189 IU/ml), similar to age-matched Israeli controls. In group 4 (8 Israeli born children of Ethiopian descent diagnosed with asthma), serum IgE showed significant elevation compared to Israeli age-matched asthmatic children (P < 0.005).  

Conclusions: High levels of IgE found in Ethiopian children on arrival to Israel declined to Israeli control levels after several years of living in the new environment. Ethiopian children born in Israel had normal levels of IgE, suggesting that environment is the main factor affecting IgE levels in this population. Israeli born Ethiopian children with asthma had significantly increased serum IgE levels compared to asthmatics of Israeli origin. These findings suggest that both environmental and genetic factors determine the level of serum IgE in these children.

Background: Analysis of the trends in psychiatric admissions and discharges is necessary to correctly plan and distribute resources, especially given the current international climate of “deinstitutionalization." Israel, too, is implementing “reform” in the national psychiatric system – to transfer psychiatric treatment from a hospital to a community setting

Objectives: To analyze admission and discharge patterns, explore trends in psychiatric hospital length of stay, and compare these characteristics between first-episode and chronic patients, between children, youth and adults, and between hospitals.

Methods: All admissions and discharges from inpatient psychiatric wards between the years 2000 and 2004 were analyzed and characterized according to age, length of hospitalization, legal status, and nature of admitting institution (state hospital, health fund, general hospital).

Results: Mean length of stay in adults decreased during the 5 year study period, from 37.6 days in 2000 to 36.4 days in 2004. In years with higher admissions, hospital stay was shorter (P < 0.05). Length of stay in psychiatric wards in general hospitals was shorter than in state hospitals (P < 0.001). In contrast to adults and children, length of stay among adolescents showed a gradual increase (P < 0.05). Involuntary hospitalization comprised 25.3% of all admissions, and 16.8% of discharged patients were readmitted within 30 days. A dramatic decrease (24.3%) in the number of chronic hospitalizations was noted.

Conclusions: Various factors may account for these developments. Protracted hospitalizations may be reduced through changes in various aspects of treatment planning and psychiatric care continuum. The decrease in number of admissions, length of stay and number of chronically admitted patients remains in line with international practices. Particular attention needs to be devoted to planning and funding so that availability of community services matches reduction in psychiatric hospitalization.
 

Background: The cause of cerebral palsy remains unknown in most cases. Factor V Leiden mutation, a common cause of hereditary thrombophilia, has been associated with CP[1].

Objectives: To analyze the prevalence of factor V Leiden (G1691A), prothrombin (G20210A), and methylenetetrahydrofolate reductase (C677T) mutations in children with CP.

Methods: Sixty-one children with CP were studied for the presence of the three gene mutations associated with thrombophilia.

Results: We found that 41% of the children with CP and 33% of the controls carry one or more of the studied mutations (P = 0.348). The prevalence of the factor V mutation was 27.9% in CP and 16.4% in controls (P = 0.127). The frequency of the other two genetic factors was even less significant. The FVL[2] mutation was found in 35% of the Arab CP patients (15/42) and in 22% of the controls from the same population (9/40) (P = 0.067).

Conclusions: Each of the genetic factors studied was shown to be related to CP. Despite the high frequency of FVL among the studied patients, we were unable to prove a significant correlation between FVL and CP, mainly because this factor is frequent in the Arab control group. In this population a trend toward significance can be seen (P = 0.067). Larger studies are needed to validate the significance of these results.

Background: Chlorpromazine is a dopamine-receptor antagonist antipsychotic agent. Because of its strong alpha-blocking and sedative actions, it has also been used as emergency therapy for extreme arterial hypertension. Published reports to date have included very small numbers of patients (i.e., 5–30).

Objectives: To analyze data on almost 500 patients who received intravenous chlorpromazine for the emergency treatment of uncontrolled symptomatic hypertension in the pre-hospital setting.

Methods: We reviewed data from 496 consecutive patients who received intravenous chlorpromazine as emergency therapy for uncontrolled symptomatic hypertension. Chlorpromazine was injected intravenously. The dose was 1 mg every 2–5 minutes until the systolic pressure was -<140 mmHg and the diastolic pressure -<100 mmHg with alleviation of symptoms.

Results: The mean dose of chlorpromazine administered was 4.5 +- 5 mg (range 1–50 mg). Only 33 patients (7%) required >10 mg. Chlorpromazine reduced the systolic blood pressure from 222.82 +- 26.31 to 164.93 +- 22.66 mmHg (P < 0.001) and the diastolic blood pressure from 113.5 +- 16.63 to 85.83 +- 11.61 mmHg (P < 0.001). The sinus rate decreased from 97.9 +- 23.5 to 92.2 +- 19.7 beats per minute (P < 0.001). These results were achieved within the first 37 +- 11 minutes.

Conclusions: Intravenous chlorpromazine is safe and effective when used as emergency treatment for uncontrolled symptomatic hypertension.
