Thrombosis is a common phenomenon in patients with malignancies. It is believed that thrombosis is multifactorial and that in addition to mechanisms directly associated with cancer and its treatment, it may also be related to the interaction between the immune system and clotting. The present work describes four cancer patients (three adults and one child) whose clinical course was characteristic of catastrophic antiphospholipid syndrome (CAPS) in intensive care units of the National Cancer Institute of Rio de Janeiro. The presence of findings similar to those in CAPS can be attributed to an unbalanced interaction between the immune system and coagulation.

Background: The detection and correction of refractive errors is one of the priorities of the World Health Organization Initiative Vision 2020.

Objectives: To determine the factors related to a child having an ocular abnormality (poor vision, refractive error or other abnormality) among schoolchildren in northern Israel.

Methods: A cross-sectional population-based study was conducted among 2113 students aged 6-7 and 13-14 years old in 70 schools in northern Israel. Medical examination included vision history, clinical eye examination and vision testing. If a parent’s informed consent was available, eye drops (cycloplegia) were delivered for fundus and retinoscopy testing. An ophthalmologist was asked to determine the need for the child’s referral for further diagnostic procedures, treatment and/or follow-up. Multivariate analysis was limited to 1708 children, using data pertaining to the ophthalmologist’s decision regarding referral, as well as vision and retinoscopy results.

Results: Vision and/or ocular abnormality was prevalent in 21.5% (95% confidence interval 17.4–26.6%), predominantly among 13-14 year olds and Jewish children. Abnormal clinical findings were found in 5.7% of the students. Retinoscopy showed a higher prevalence of hypermetropia among 6-7 year olds and a higher prevalence of myopia and astigmatism among the 13-14 year olds. The multivariate analysis suggests an independent effect of retinoscopy abnormality (odds ratio = 3.85), vision abnormality (OR [1]= 2.42), Jewish ethnicity (OR = 1.62) and 13-14 year old age group (OR = 1.26) on the ophthalmologist’s referral decision.

Conclusions: Vision and/or ocular abnormality is an important health problem among schoolchildren in northern Israel. The independent effect of ethnicity and age on the ophthalmologist’s referral decision should be further explored.

Background: Previous studies led to the recommendation to schedule planned elective cesarean deliveries at or after 39 weeks of gestation, and not before 38 weeks. The question is whether this practice is appropriate in face of possible risks to the newborn should the pregnancy have to be ended by cesarean section before the scheduled date.

Objectives: To compare the outcomes of newborn infants who were delivered on their scheduled day by elective cesarean section versus those who required delivery earlier.

Methods: This single-center retrospective study was based on medical records covering a period of 18 months. We compared the neonatal outcomes of 272 infants delivered by elective cesarean section as scheduled (at 38.8 ± 0.8 weeks gestation) and 44 infants who had to be delivered earlier than planned (at 37.9 ± 1.1 weeks). 

Results: We found no morbidity directly related to delivery by cesarean section before the scheduled date. There were no significant differences in the need for resuscitation after delivery. Although more of the infants who were delivered early were admitted to intensive care and overall stayed longer in the hospital (5.8 ± 7.3 vs. 3.9 ± 0.8 days, P < 0.02), their more severe respiratory illness and subsequent longer hospitalization was the result of their younger gestational age. Transient tachypnea of the newborn was associated with younger gestational age at delivery in both groups.

Conclusions: We suggest continuing with the current recommendation to postpone elective cesarean singleton deliveries beyond 38–39 weeks of gestation whenever possible.

Background: The prevalence of thyroid dysfunction in early pregnancy in Israel is not known.

Objectives: To assess the rate of abnormal thyroid-stimulating hormone (TSH) tests in low risk pregnant women attending a community clinic in Israel.

Methods: We conducted a retrospective analysis of the charts of low risk pregnant women (n=303) who had undergone a TSH screening during the first trimester of pregnancy at Clalit Health Services Women's Health Centers in Ashkelon and Tel Aviv. The TSH normal range during first trimester was considered to be 0.1–2.5 mIU/L.

Results: The TSH levels ranged from 0.04 to 13.3 mIU/L (median 1.73 mIU/L, mean 1.88 mIU/L). The rate of abnormal TSH was 25.6%, with low TSH 2.3% and high TSH 23.4%. The prevalence of abnormal TSH was not influenced by gravidity (primigravidas versus multigravidas) or place of residence (Ashkelon or Tel Aviv).

Conclusions: In view of the high prevalence of abnormal TSH (25.6%) in pregnant women in Israel during the first trimester, a universal country-wide screening should be considered.

Background: The prevalence of ADHD is controversial, with many feeling that this disorder is over- or under-diagnosed.

Objectives: To study the prevalence of attention-deficit/hyperactivity disorder (ADHD) and its association with socio-demographic characteristics, comorbid mental disorders, medical services, and methylphenidate use in the Israeli adolescent population.

Methods: The Israel Survey of Mental Health among Adolescents was conducted in a representative national sample of 14–17 year olds and their mothers. The Development and Well-Being Assessment was administered to identify DSM-IV diagnoses of ADHD and comorbid mental and learning disorders, and the results were verified by senior child psychiatrists. Respondents were also asked about their use of medical services and psychotropic drug intake in the past 12 months.

Results: Three percent of the adolescents met the DSM-IV criteria for ADHD. ADHD was significantly associated with gender (higher prevalence in boys than girls), ethnicity (higher prevalence in Jews than Arabs/Druze), referral to a medical professional, and maternal help-seeking for the emotional or behavioral problems of the adolescent. Medication was prescribed to 2.9% of adolescents: 34.6% with a diagnosis of ADHD had not been prescribed methylphenidate in the past year, and 34.6% of the medicated subjects did not have a diagnosis of ADHD. None of the Arab/Druze adolescents was receiving stimulants compared to 3.7% of the Jewish adolescents.

Conclusions: Despite advances in public awareness of mental disorders in youth, a substantial proportion of older Israeli adolescents, especially from minority groups, are under-diagnosed or untreated. At the same time, many, especially from the Jewish majority, are over-diagnosed and potentially over-treated. Ethnic disparities in rates of mental health care highlight the urgent need to identify and overcome barriers to the recognition and treatment of these conditions.

Background: Low back pain (LBP) is chronic disease without a curative therapy. Alternative and complementary therapies are widely used in the management of this condition.  

Objectives: To evaluate the efficacy of home application of Dead Sea mud compresses to the back of patients with chronic low back pain (LBP).

Methods: Forty-six consecutive Patients suffering from chronic LBP were recruited. All patients were followed at the Soroka University Rheumatic Diseases Unit.  The patients were randomized into two groups: group 1 was treated with mineral-rich mud compresses, and group 2 with mineral-depleted compresses. Mud compresses were applied five times a week for 3 consecutive weeks. The primary outcome was the patient’s assessment of the overall back pain severity. The score of the Ronald & Morris questionnaire served as a secondary outcome.

Results: Forty-four patients completed the therapy and the follow-up assessments: 32 were treated with real mudpacks and 12 used the mineral-depleted packs. A significant decrease in intensity of pain, as described by the patients, was observed only in the treatment group. In this group, clinical improvement was clearly seen at completion of therapy and was sustained a month later. Significant improvement in the scores of the Roland & Morris questionnaire was observed in both groups.

Conclusions: The data suggest that pain severity was reduced in patients treated with mineral-rich mud compresses compared with those treated with mineral-depleted compresses. Whether this modest effect is the result of a “true” mud effect or other causes cannot be determined in this study. 

The major autoantigens in the inflamed synovium in rheumatoid arthritis (RA) are citrullinated peptides. Citrullinated peptides are employed in diagnostic kits for detection of anti-citrullinated protein antibodies (ACPA), a serological marker with high specificity and sensitivity in the diagnosis of RA, and have been included in the new ACR/EULAR classification criteria for RA. ACPA-positive RA patients suffer from an erosive and more aggressive disease compared to ACPA-negative patients. In view of the mounting indications that ACPA plays a seminal role in the pathogenesis of RA, it might be valuable to pursue a specific treatment aiming ACPA as a target. We found that citrullinated peptides, which contain a unique amino acid, citrulline, alter the protein structure within the connective tissue, leading to tolerance breakdown and triggering the autoimmune response in RA. However, with different doses and routes of administration, citrullinated peptides can promote immune tolerance rather than induction of disease.
