Background: In Israel, preventive services for mothers and children are provided mainly by the Ministry of Health through a network of Maternal and Child Health clinics, and partly by municipalities and health maintenance organizations. Utilization of the MCH[1] clinics for prenatal care has declined during the last decades.

Objective: To study the utilization and satisfaction with prenatal care services following the introduction of the National Health Insurance Law.

Methods: The study population comprised a national sample of Jewish and Arab women who were interviewed by telephone regarding the following: main service utilized for prenatal care, physician and nursing visits, satisfaction with care, and demographic and other characteristics. The response rate was 92% among Jewish women and 88% among Arab women.

Results: Twenty percent of the Jewish and 52% of the Arab women selected MCH clinics as the main service for prenatal care. The great majority of the study population attended the HMO[2] services (clinics, independent physicians, women’s health centers), while 7% of the Jewish and 4% of the Arab women visited a private clinic. The predisposing factors affecting the women's choice were educational level, ethnic group, religiosity, district of residence, and type of HMO. The mean number of physician visits was more than the eight visits recommended. Forty percent of the sample visited with three or more physicians at different services. More than 50% of the women had no appointment with a nurse, mainly those who chose the services of an HMO clinic, independent physician, or private physician. Satisfaction with the physician, nurse, and physical structure of the main service chosen for prenatal care was high.

Conclusions: Since the majority of women preferred the HMO services, the merging of prenatal care with curative care provided by the HMOs has to be considered. Public health nurses should be integrated in the service, and their specific role needs to be defined.

Background: Recent advances in immunosuppressive therapy have led to a substantial improvement in the outcome of kidney transplantation. Living unrelated donors may become a source of additional organs for patients on the kidney waiting list.

Objectives: To study the impact of combination of calcineurin inhibitors and mycophenolate-mofetile, together with steroids, on outcomes of living related and unrelated transplants. 

Methods: Between September 1997 and January 2000, 129 patients underwent living related (n=80) or unrelated (n=49) kidney transplant. The mean follow-up was 28.2 months. Immunosuppressive protocols consisted of MMF[1] with cyclosporine (41%) or tacrolimus (59%), plus steroids. Patient and graft survival data, rejection rate, and graft functional parameters were compared between the groups.

Results: LUD[2] recipients were older (47.8 vs. 33.6 years) with higher number of re-transplants (24.5% vs. 11.2% in LRD[3] recipients, P < 0.05). Human leukocyte antigen matching was higher in LRD recipients (P < 0.001). Acute rejection developed in 28.6% of LUD and 27.5% of LRD transplants (P = NS). Creatinine levels at 1, 2 and 3 years post-transplant were 1.6, 1.7 and 1.7 mg/dl for LRD patients and 1.5, 1.5 and 1.3 mg/dl for LUD recipients (P = NS). There was no difference in patient survival rates between the groups. One, 2 and 3 year graft survival rates were similar in LRD (91.3%, 90% and 87.5%) and LUD (89.8%, 87.8% and 87.8%) recipients.

Conclusions: Despite HLA[4] disparity, rejection and survival rates of living unrelated transplants under current immunosuppressive protocols are comparable to those of living related transplants.

The Arab population of Israel is relatively young. However, a significant increase is expected in the number of elderly Arabs in the coming years. At the end of 2001 there were 38,500 Arab elderly, but their number is expected to reach 92,100 by 2020. This will represent a nearly 2.5-fold increase in absolute numbers. As the population ages, the number and percentage of people with chronic diseases and related disabilities will rise significantly. While the Arab elderly are much younger than the Jewish elderly, they are more disabled and therefore have greater medical and nursing needs. An extremely important measure of the need for formal services is an elderly person’s functional ability, especially the ability to live independently. The percentage of Arab elderly who are disabled and need help with activities of daily living is two times higher than that of the Jewish elderly population. At present, 30% of the Arab elderly (39% of the women and 20% of the men), compared to 14% of Jewish elderly (17% of the women and 11% of the men), need help in at least one ADL[1] (bathing, dressing, eating, mobility in the home, rising and sitting, getting in and out of bed). Concomitant with demographic changes are forces that affect the ability of informal support systems to provide care. For example, the rising number of Arab women in the labor force together with changes in elderly peoples' living arrangements have increased the need for formal services to share responsibility for the elderly with families. As services are developed, questions arise regarding the extent to which they have been adapted to the culture and norms of Arab society and meet that society’s unique needs. This paper elaborates on some of these issues.

Background: Some studies have indicated a possible link between cigarette smoking and hearing loss.

Objectives: To analyze the association between smoking and hearing loss, other than that induced by noise, and to characterize the type of HL impairment found in smokers.

Methods: We conducted a retrospective cross-sectional study in 13,308 men aged 20±68 (median 34.6 years) who underwent a hearing test as part of a routine periodic examination. For each subject, age, smoking status (current, past or non-smokers) and number of cigarettes per day were noted and a hearing test was performed. The test was performed in a sealed, soundproof room by an experienced audiologist and included pure tone audiometry of 250±8,000 Hz. The audiograms were analyzed and subjects were accordingly divided into two groups: those with HL and at least one of the following impairments in at least one ear: sensorineural, conductive or mixed; and those with no hearing loss (control). Audiograms showing HL typical to noise exposure were excluded.

Results: The prevalence of any type of HL among subjects <35 years was 4.5%, compared to 10.5% among those >35 years (P < 0.0001). A significantly higher incidence of any type of HL was found in current (11.8%) and past smokers (11.7%) than in non-smokers (8.1%) (P < 0.0001). The risk increment of the smoking status for developing HL among subjects under age 35 was 43%, and 17% among those above 35 years. Both mild, flat, sensorineural impairment and conductive impairment were found to be associated particularly with smoking (odds ratio 2.2 and 1.9, respectively).

Conclusions: The incidence of HL unrelated to noise exposure is higher in smokers than in non-smokers, and in young adults the effect is greater.
 

Background: The prevalence of clinical manifestations and laboratory parameters in systemic lupus erythematosus differ among various ethnic groups. Few studies have reported on SLE[1] in Arabs.

Objectives: To summarize the demographic, clinical and laboratory features of Arab SLE patients and to compare them with other series from different Arab countries.

Methods: We reviewed the charts of all Arab SLE patients who had been seen at the Carmel Medical Center in Haifa, the Nazareth Hospital and the Holy Family Hospital in Nazareth, and a professional clinic (a referral outpatient clinic of the largest health maintenance organization in Israel) in Acre – all cities in northern Israel. Only patients with symptoms of more than one year were included. Demographic, clinical and laboratory parameters were documented and compared with those of four series from different Arab countries.

Results: The study group comprised 34 patients. The majority of the patients was Moslem; there were a few Druze and one Christian. There was no statistical difference between our patients and any of the other Arab series in terms of arthritis, neuropsychiatric manifestations and VDRL. The presence of serositis and mucocutaneous manifestations was significantly lower in our series compared to some of the other series. However, there was significantly less renal involvement in our patients compared to each of the other series.

Conclusions: The prevalence of most clinical and laboratory parameters in Israeli Arab SLE patients is comparable to that of other series of SLE patients from different Arab countries. The prevalence of renal involvement in Israeli Arab SLE patients seems to be lower than in SLE patients from different Arab countries.

Background: Prevention of cigarette smoking is an important issue in public health policy. Since most adult smokers began smoking in childhood, understanding behavor­ial factors associated with smoking initiation would contribute to smoking initiation programs. Health-related behavior may vary between different ethnic groups.

Objectives: To determine the prevalence of smoking among Jewish and Arab adolescents in Jerusalem, and whether there are differences in smoking initiation between the two ethnic groups.

Methods: We carried out a cross-sectional survey of all students in the 6th to 11th grades (age range 11-17 years) of a Jewish school and an Arab school in the Jerusalem area, using an anonymous self-completion questionnaire. A total of 791 questionnaires was analyzed, 479 from the Jewish students and 312 from the Arab students.

Results: The lowest prevalence of smoking was found among Arab female students and the highest among Jewish female students (9% vs. 41%, P<O.OO1). The prevalence of smoking among Jewish and Arab males was similar. More Arab female students smoked than their mothers. Peer pressure seemed to be a more important factor among Jewish students.

Conclusions: This study demonstrated the presence of ethnic differences in smoking prevalence and the reasons for smoking among adolescents in Israel. These results suggest the need for specific smoking prevention policies for different ethnic groups.

Background: Achondroplasia is the most frequent form of disproportionate short stature, characterized by rhizomelic shortening of the limbs. This disorder is inherited as an autosomal dominant trait, although most of the cases are sporadic, a result of a de novo mutation. A recurrent glycine to arginine mutation at codon 380 (G380R) in the transmembrane domain of the fibroblast growth factor receptor 3 gene was found to cause achondroplasia among different populations. This is most uncommon in other autosomal dominant genetic diseases.

Objectives: To determine whether this mutation is also common among Jewish patients from diverse ethnic groups and among the Arab population in Israel.

Methods: We examined the G380R mutation (G>A and G>C transition) and the mutation G375C (G>T transition at codon 375) in 31 sporadic patients and in one family diagnosed clinically to have achondroplasia.

Results: We found the G>A transition at codon 380 in 30 of our patients and the G>C transition in one patient. We were not able to detect any of the three mutations in two patients with an atypical form of achondroplasia.

Conclusions: Our results further support the unusual observation that nucleotide 1138 of the FGFR3 gene is the most mutable nucleotide discovered to date across different populations.

Background: A high rate of consanguineous marriages exists within the Israeli Arab community, with approximately half occurring between first cousins. This contributes towards a high incidence of congenital malformations and autosomal recessive diseases, many of which are detectable at prenatal diagnosis.

Objectives: To assess the levels of both awareness and acceptance regarding prenatal diagnosis and termination of pregnancy among a group of Arab women in order to devise the optimal means of providing genetic counseling and general health services.

Methods: A total of 231 Arab women of childbearing age were interviewed 3 days postpartum to assess their knowledge of prenatal diagnosis and termination of pregnancy, their willingness to undergo prenatal diagnosis, and their opinions on termination of pregnancy in the event of a severely affected fetus.

Results: Half the women believed that prenatal testing is not an effective (or accurate) tool for diagnosing an affected fetus. A quarter had poor knowledge on prenatal diagnosis, and a quarter believed that prenatal diagnosis does provide the correct diagnosis. Ninety-five percent said they would agree to undergo prenatal diagnosis; and in the event of a severely affected fetus, 36% said they would agree to a termination of pregnancy, 57% said they would not, and 7% were undecided.

Conclusions: There is a need for special intervention programs, with guidance by health professionals, geneticists and religious authorities, that will inform this population on the increased risk associated with consanguinity, stress the importance and effectiveness of prenatal testing to identify severe congenital malformations, and help them to accept prenatal diagnosis and termination of pregnancy if indicated.

Background: Hypertension is one of the most prevalent vascular diseases in the adult population. It is an important determinant of atherosclerosis in adolescents and young adults. There is to date no information on blood pressure in children of the Israeli Arab population.

Objectives: To study blood pressure in Israeli Arab children and adolescents.

Methods: Blood pressure measurements were taken in the supine position in 4,488 Israeli Arab children and adolescents of both sexes aged 6–17 years. Height and weight were also determined. Correlation was investigated between systolic and diastolic blood pressure, body mass index, gender, and age.

Results: The systolic and diastolic blood pressures were similar in both sexes for all age groups up to 14 years of age. Systolic blood pressure was significantly (P<0.001) higher in males aged 15–17 years  (120±13 vs. 111±12 mmHg, 123±13 vs. 113±14.0 mmHg, and 123±18 vs. 111±14 mmHg, respectively). Diastolic blood pressure was higher in males aged 15–17, with a statistically significant difference for age 17 only (75±12 vs. 69±13 mmHg). Blood pressure was elevated in 322 students in the initial screening (7.17%), with a decrease to 2.18% when this group was rescreened 2 weeks later. The systolic blood pressure in our group is higher than that in Jewish Israeli children of Asian and North African origin, and in American children. It is similar to the systolic blood pressure of European children and Jewish children born in Israel. The diastolic blood pressure in our group is higher than that in all groups of Israeli Jewish children and American children of different ethnic groups.

Conclusions: Israeli Arab children and adolescents have higher blood pressure levels than their Israeli Jewish counterparts. Further studies are required to confirm this observation.
