Background: The age-standardized incidence rate of invasive cervical cancer in Israeli Jewish women is persistently low. Selected demographic characteristics of Israeli Jewish women with cervical squamous cell carcinoma (SCC) were reported recently. 

Objectives: To assess selected clinical characteristics of Israeli Jewish women with cervical SCC.

Methods: Included were all Israeli Jewish women with SCC diagnosed during the 3-year period 2002­–2004. Data were obtained from the Israel National Cancer Registry and the Central Population Registry. Discharge summaries of the patients were reviewed and clinical data were abstracted.

Results: The study was based on 350 Israeli Jewish women with histologically confirmed cervical SCC diagnosed during the 3-year study period. The median age of the patients was 50.3 years. The most common main complaint was discharge/bleeding (35.7%) and only a small percentage (7.4%) was diagnosed subsequent to an abnormal cytological smear. The rate of patients diagnosed in stage I was 47.7%. The overall absolute 5-year survival and survival in stage I was 70% and 83.8% respectively. The rate of Israeli born patients diagnosed in stage I and their overall absolute 5-year survival was significantly higher than in the other ethnic groups.

Conclusions: Age, the most frequent main complaint, the percent of patients diagnosed in stage I and the 5-year survival (overall and in stage I) are similar to data in other countries. The survival of Israeli born women seems to be better than that of other ethnic groups.
 

Background: Human parvovirus B19 is a global and common infectious pathogen in humans, primarily in children.

Objectives: To assess the immunoglobulin G seroprevalence of B19 in children in Israel.

Methods: Overall, 128 previously healthy children (1.5–17 years old) hospitalized for various diseases other than acute human parvovirus B19 infection were assessed for IgG[1] to the virus by enzyme-linked immunosorbent assay. 

Results: The IgG seroprevalence increased from 22% in children aged 1.5–9 years to 52% in older children (P = 0.001).

Conclusions: Our data suggest that most acute parvovirus B19 infections in Israel occur in the early school years, and that by 18 years of age 50% of Israeli children have been infected by the virus.

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: Balneotherapy is an established treatment modality for musculoskeletal disease. However, few studies have examined the efficacy of spa therapy in elderly patients with degenerative spine and joint diseases.

Objectives: To assess the effects of balneotherapy on chronic musculoskeletal pain, functional capacity, and quality of life in elderly patients with osteoarthritis of the knee or chronic low back pain.

Methods: A total of 81 patients enrolled and the results of 76 were analyzed. Subjects underwent a 1 day course of 30 minute daily baths in mineral water. Changes were evaluated in the following parameters:  pain intensity, functional capacity, quality of life, use of non-steroidal anti-inflammatory or analgesic drugs, subjective disease severity perceived by the patients, investigator-rated disease severity, and severity of pain perceived by the patients.

Results: Compared to baseline, all monitored parameters were significantly improved by balneotherapy in both investigated groups. Moreover, the favorable effect was prolonged for 3 months after treatment.

Conclusions: This study showed that balneotherapy is an effective treatment modality for elderly patients with osteoarthritis of the knee or with chronic low back pain, and its benefits last for at least 3 months after treatment.
 

Background: Many centers in Israel still use pre-1970 reference data for neonatal weight, length and head circumference. A recently published population-based reference overestimated the weight of premature infants.

Objective: To develop a national reference for birth weight, birth length, and head circumference by gestational age for singleton infants in Israel.

Methods: Data were collected on all singleton live births documented in the neonatal registry of Rabin Medical Center from 1991 to 2005 (n=82,066). Gestational age estimation was based on the last menstrual period until 1977 and early fetal ultrasound thereafter. Neonates with an implausible birth weight for gestational age (identified by the rule of median ± 5 standard deviations or expert clinical opinion) were excluded. Reference tables for fetal growth by gestational age were created for males and females separately.

Results: The growth references developed differed markedly from the Usher curves currently used in our department. Compared to the recently published population-based birth weight reference, our data were free of the problem of differential misclassification of birth weight for gestational age for the premature infants and very similar for the other gestational age groups. This finding reinforced the validity of our measurements of birth weight, as well as of birth length and head circumference.

Conclusions: Use of our new (birth length and head circumference) and improved (birth weight) gender-specific hospital-based reference for fetal growth may help to define normal and abnormal growth in the neonatal population of Israel and thereby improve neonatal care and public health comparisons.
 

Background: Age-related macular degeneration is the most common cause of legal blindness in the developed world including Israel. Ethnic background is a risk factor for advanced AMD[1] in several populations, however the relative prevalence of this disease in different ethnic groups in the Middle East is unknown.

Objectives: To compare the prevalence of advanced AMD in Arabs and Jews in Israel.

Methods: We performed a retrospective analysis of two independent groups of patients: the first group comprised a sequential series of Jerusalem residents who underwent photodynamic therapy for neovascular AMD (PDT[2] group), and the second group consisted of all individuals in Jerusalem who received a blind certificate due to AMD (legal blindness group). Control groups were assessed to exclude inherited ethnic associated bias in the two study groups.

Results: The PDT group included 146 patients: 142 were Jews (97.3%) and 4 were Arabs (2.7%). The legal blindness group included 340 Jerusalem residents: 326 Jews (96%) and 14 Arabs (4%). The number of Arab AMD patients in the two groups was lower than expected based on the ethnic composition of the age-matched Jerusalem population (P = 0.0002 for the PDT group, and P < 0.0001 for the legal blindness group). By contrast, the number of non-AMD Arab patients who were treated in the same clinic and the number of Arabs who received a blind certificate for diabetic retinopathy was not different from expected based on their relative number in the Jerusalem population.

Conclusions: Advanced AMD is less common in the Arab than the Jewish population of Jerusalem. Genetic and environmental factors may account for this difference. A population-based study is required to assess the overall prevalence of AMD in Jews and Arabs.

Objectives: To compare leukocyte counts and blood levels of various inflammatory cytokines in children and adults diagnosed with community-acquired bronchopneumonia.

Methods: We prospectively evaluated all pediatric and adult patients admitted for bronchopneumonia based on clinical and chest X-ray findings.. Blood was drawn for complete blood count and serum concentration of the following cytokines: granulocyte colony-stimulating factor, interleukins-6, 8 and 10, interferon-gamma, tumor necrosis factor, as well as matrix metalloproteinase-9 and intercellular adhesion molecule-1.

Results: There were 31 children and 32 adults. The patients in both groups had similar parameters of infection severity. None of them required admission to the Intensive Care Unit. Mean (± SD) leukocyte counts in the pediatric and adult groups were 21,018/mm (± 10,420) and 12,628/mm (± 6735) respectively (P = 0.02). Age was inversely correlated with leukocytes in the pediatric group (P = 0.0001). A significant inverse correslation was also found between age and platelet counts. Although cuytokine levels in both groups were not significantly different, age was

Conclusions: The immune response in community-aquired bronchopneumonia is, at least partly, age-dependent.

Endometrial polyps are a frequent finding in infertile patients. Little is known about the true prevalence of polyps in infertile patients. It is unproved whether polyps are causative of infertility, or whether surgical polypectomy by hysteroscopy improves the likelihood of successful conception. This article reviews endometrial polyps in reproductive-age fertile and infertile women.

Background: Benign paroxysmal positional vertigo is a common and treatable vestibular disorder characterized by attacks of positional vertigo. Although elderly patients often complain about unsteadiness, the symptom of positional vertigo is seldom reported. Several studies on BPPV[1] in the elderly reveal a low success rate in the treatment of this entity.

Objectives: To assess the clinical characteristics and treatment outcome of BPPV in elderly patients and to compare them with those of the general population treated at our dizziness clinic.

Methods: We reviewed the medical records of 23 patients above age 75 who were treated at our dizziness clinic for BPPV during the years 1998–2004. Their clinical data, BPPV characteristics and treatment outcome were compared with the data of 30 consecutive BPPV patients who represented the general population.

Results: No differences in gender distribution, duration of BPPV, treatment responsiveness or recurrence rate were found between elderly patients as compared to the general population. The duration of the last attack of positional vertigo was found to be longer in the elderly, probably due to the delay in recognition of symptoms and accessibility of a dizziness clinic.

Conclusions: Our study shows that BPPV characteristics and treatment effectiveness, as measured by negative Dix-Hallpike maneuver, are not age-dependent and there is no need for a special approach or cautiousness in prognosis prediction. It is important to search actively for this condition since treatment leads to amelioration of unsteadiness and improved well-being in these patients.

Objective: To assess the prevalence of diabetes in an Arab community, the contribution of obesity to diabetes development, and the therapeutic potential of a preventive program.

Methods: Data were obtained from the medical files of diagnosed diabetes patients attending a primary care clinic in an Arab village in northern Israel.

Results: Type 2 diabetes was diagnosed in 323 patients of whom 63% were women. The prevalence of diabetes below age 65 years was significantly higher among women than men. Diabetic women were younger than men at diagnosis (48.27 vs. 59.52 respectively) and were found to have higher body mass index (34.35 vs. 30.04 respectively) at diagnosis. The age at diagnosis of diabetes was strongly correlated with BMI[1] (r = 0.97, P < 0.0001).

Conclusions: Women of Arab origin are at higher risk of developing type 2 diabetes compared to men. Obesity in women seems to be associated with higher diabetes risk as well as earlier appearance of the disease. Therefore, they will have the disease for longer and, consequently, a higher risk for complications.
