Background: The American Academy of Pediatrics recently published recommendations for the red reflex assessment in the newborn period to detect and treat ocular disorders as early as possible, and to prevent lifelong visual impairment and even save lives. The test is technically simple to perform, non-invasive, requires minimal equipment and can detect a variety of ocular pathologies including cataracts and retinal abnormalities. No specific national guidelines exist on this issue.

Objectives: To document the implementation of red reflex examination in routine neonatal care and present the findings.

Methods: Our clinical experience following implementation of the red reflex test into the newborn physical examination in a single center was reviewed. In addition, an electronic mail questionnaire was sent to all neonatology departments in Israel regarding the performance of the red reflex test.

Results: During 2007–2008, five infants were identified with congenital cataracts at days 2–6 of life prior to discharge from hospital. Surgery was performed in one infant at age 2 months and all infants underwent a thorough follow-up. The incidence of congenital cataract in our center was 1:2300. Less than half the neonatology departments have endorsed the AAP[1] recommendation and perform the red reflex test routinely.

Conclusions: Abnormal red reflex test after delivery enables a rapid ophthalmologic diagnosis, intervention and close follow-up. We recommend that red reflex screening be performed as part of the newborn physical examination if abnormal, an urgent ophthalmologic referral should be made.

Background: Adenoviral infection in children undergoing stem cell transplantation is associated with significant morbidity and mortality. Identification of adenoviral infection by polymerase chain reaction from blood facilitates accurate and rapid diagnosis and surveillance. The incidence of adenoviral infection among children undergoing SCT[1] in Israel is not known.

Objective: To estimate the incidence of adenoviral infection in pediatric SCT patients and to characterize the morbidity associated with proven infection.

Methods: Blood samples obtained weekly from children who underwent allogeneic SCT were retrospectively tested for adenovirus using standard PCR[2]. A total of 657 samples collected from 32 patients were examined. Correlation was made between the presence of adenovirus in samples and clinical records.

Results: Of the 32 patients 4 had adenoviral infection by PCR (12.5%). Clinical disease was present in all four patients concurrent with positive PCR. Gastrointestinal complaints and abnormal hepatocellular enzymes were uniformly present. One patient died due to disseminated disease. T cell depletion was a significant risk factor for adenoviral infection (P = 0.03).

Conclusions: In the patient population studied, the incidence of adenoviral infection in children undergoing SCT was 12.5%. The combination of gastrointestinal symptoms and abnormal hepatocellular enzymes should raise the suspicion of adenoviral infection, especially when occurring during the first few months after SCT. 

Background: Due to the absence of accurate tools and appropriate photographic material there is a paucity of objective studies on facial aging in the modern literature.

Objectives: To measure changes in two elements of the face: brow ptosis and cheek mass migration, using an objective tool that we developed, which we then used to evaluate facial aging in two subjects, studying serial professional photographs over a 25 year period.

Methods: We studied the photographic atlas of the "Brown Sisters," a record of the yearly group photograph of four sisters, taken by the photographer Nicolas Nixon. For technical reasons, only two of the sisters fulfilled the criteria we set for the study. We used the interpupillary distance of each photograph studied to standardize the brow height and cheek mass distance from the interpupillary line.

Results: We observed progressive medial brow descent occurring at about the age of 30, with apparent stabilization thereafter. In contrast, there was a continuous process of lateral brow descent through the years. A process of gradual cheek mass descent was noted in the second half of the third decade.

Conclusions: Our results indicate that the dynamic brow changes start in the second half of the third decade, with more significant lateral brow descent than medial brow descent. The cheek mass reflective point moves in an inferior-lateral direction. The tool we developed can be used to follow aging changes and postoperative results, thereby helping the surgeon achieve true rejuvenation surgery.

Background: Negative-pressure therapy for the closure of wounds, a technique to accelerate secondary wound healing, is clinically available as the V.A.C.™ system (KCI Inc, San Antonio, TX, USA). Budgetary considerations in our institution precluded widespread use of the expensive V.A.C.™ system in routine cases.

Objectives: To develop a less expensive comparably effective dressing, based on the same principles.

Methods: We used our “homemade” system to treat 15 patients with appropriate complex wounds. Their hospital charts were reviewed and assessed retrospectively. Cost analysis was performed comparing our dressing with the V.A.C.™ system.

Results: Our homemade negative-pressure wound treatment system obtained results similar to what one could expect with the V.A.C.™ System in all parameters. Complications encountered were few and minor. Cost per day using our negative-pressure system for a 10 cm² wound is about US$1, as compared to US$22, utilizing the V.A.C.™ System.

Conclusions: Our homemade negative-pressure system proved to be a good cost-effective treatment for wound closure in hospitalized patients, yielding results comparable to those of the more expensive V.A.C.™ system.
 

Background: Bisphosphonates are effective in the prevention and treatment of osteoporosis, yet their use is suboptimal.

Objectives: To measure bisphosphonate compliance among first-time users and identify factors associated with compliance.

Methods: We conducted a prospective follow-up of all women aged 45+ in the second largest health management organization in Israel who were prescribed bisphosphonates for the first time. The 4448 women were classified by drug dosage. Persistence and adherence measures of compliance were calculated for each woman over a 1 year period.

Results: Mean bisphosphonate persistence over a year was 216 days, with a mean medication possession ratio of 66%. Women whose medication was changed, whether from weekly to daily or daily to weekly, always had better persistence rates than those who consistently took the original dose. Persistence rates were as follows: 264 days for women who switched back and forth between daily and weekly doses, 229 days for those who switched from daily to weekly, 222 days for those who took the dosage weekly only, 191 days for those who switched to daily dosage, and 167 days for those who took the dosage daily only (P < 0.001). Switchers were also more likely to have adequate adherence rates (MPR[1] ≥ 80%): 81.3%, 76.6%, 67.5%, 61.3% and 52.2% respectively (P < 0.001). More than 20% of women stopped taking their medication within the first month. Women with higher supplemental insurance (offering significant discounts for weekly dose medications) had better persistence rates: 221 vs. 208 days (P = 0.03). Younger women and women on national pension insurance had the lowest persistence rates: 204 and 209 days respectively.

Conclusions: While weekly bisphosphonate takers had better compliance rates, persistence and adherence rates were inadequate for all groups. Changing medication to meet the needs of the patient, discounting weekly medications, and providing follow-up within the first months of prescription may promote compliance. 

Background: Germline mutations in BRCA1 and BRCA2 genes account for only 20–40% of familial breast cancer cases. The CHEK2 gene encodes a checkpoint kinase, involved in response to DNA damage, and hence is a candidate gene for breast cancer susceptibility. Indeed, the CHEK2*1100delC truncating mutation was reported in a subset of mostly North European breast cancer families. The rate of the CHEK2*1100delC variant in the Ashkenazi* Jewish population was reported to be 0.3%.

Objectives: To evaluate whether CHEK2 germline mutations contribute to a breast cancer predisposition in Ashkenazi-Jewish high risk families.

Methods: High risk Ashkenazi Jewish women, none of whom was a carrier of the predominant Jewish mutations in BRCA1/BRCA2, were genotyped for germline mutations in the CHEK2 gene by exon-specific polymerase chain reaction followed by denaturing gradient gel electrophoresis and sequencing of abnormally migrating fragments.

Results: Overall, 172 high risk women were genotyped: 75 (43.6%) with breast cancer (average age at diagnosis 49.6 ± 9.6 years, mean ± SD) and 97 asymptomatic individuals (age at counseling 48.3 ± 8.2 years). No truncating mutations were noted and four previously described missense mutations were detected (R3W 1.2%, I157T 1.2%, R180C 0.6% and S428F 5%), one silent polymorphism (E84E 20.5%) and one novel missense mutation (Y424H 1.2%). Segregation analysis of the I157T and S428F mutations (shown to affect protein function) with the cancer phenotype showed concordance for the CHK2*I157T mutation, as did two of three families with the CHK2*S428F mutation.

Conclusions: CHEK2 missense mutations may contribute to breast cancer susceptibility in Ashkenazi Jews.

Background: Numerous studies have shown an association between asthma and mental disorders. While elevated rates of asthma have been noted among psychiatric patients with anxiety disorders and post-traumatic stress disorder, several studies have found elevated rates of mental disorders among asthma patients. Such studies, however, have generally relied upon questionnaires and assessment by non-specialist physicians to diagnose mental disorders and asthma.

Objectives: To examine a possible association between asthma and psychiatric diagnoses in Israeli military recruits and soldiers.

Methods: In this cross-sectional study we compared the prevalence of mental diagnoses in asthmatic recruits and soldiers to that in non-asthmatic recruits and soldiers. A total of 195,903 recruits and soldiers were examined by Israel Defense Forces recruiting offices and fitness boards. Diagnoses of asthma were based on a pulmonologist's diagnosis, including spirometry at rest and exercise testing as indicated; diagnoses of mental disorders were based on examination by a psychiatrist.

Results: The prevalence of asthma was found to be 7.8% (current) and 9.8% (lifetime). The prevalence of mental disorders was 13.4%. Current asthma was associated with an increased likelihood of any mental disorder (OR = 1.20, 95% CI = 1.15–1.26), and specifically with mood and anxiety disorders (1.31, 1.19–1.46), introvert personality disorders (1.20, 95% 1.12–1.28) and adjustment disorder (1.43, 1.26–1.62). Lifetime asthma was associated with an increased likelihood of the same disorders, but the association was not as powerful.

Conclusions: The results validate the previously documented association between asthma and mental disorders, using a sample of unprecedented size and improved methodology. A multidisciplinary approach to asthma that incorporates mental health professionals in the treatment of poorly controlled asthma and perhaps of asthma in general is recommended.
 

Background: Echocardiographic assessment of left ventricular function includes calculation of ejection fraction and regional wall motion analysis. Recently, speckle imaging was introduced for quantification of left ventricular function.

Objectives: To assess LVEF[1] by speckle imaging and compare it with Simpson’s method, and to assess the regional LV strain obtained by speckle imaging in relation to conventional echocardiographic scores.

Methods: Thirty consecutive patients, 28 with regional LV dysfunction, underwent standard echocardiographic evaluation. LV end-diastolic volume, LV end-systolic volume and EF were calculated independently by speckle imaging and Simpson’s rule. The regional peak systolic strain presented by speckle imaging as a bull's-eye map was compared with the conventional visual estimate of echo score.

Results: Average EDV[2] obtained by speckle imaging and by Simpson’s method were 85.1 vs. 92.7 ml (P = 0.38), average ESV[3] was 49.4 vs. 48.8 ml (P = 0.94), calculated EF was 43.9 vs. 50.5% (P = 0.08). The correlation rate with Simpson’s rule was high: 0.92 for EDV, 0.96 for ESV, and 0.89 for EF. The peak systolic strain in two patients without wall motion abnormality was 17.3 ± 4.7; in normal segments of patients with regional dysfunction, peak systolic strain (13.4 ± 4.9) was significantly higher than in hypokinetic segments  (10.5 ± 4.5) (P < 0.000001). The strain in hypokinetic segments was significantly higher than in akinetic segments (6.2 ± 3.6) (P < 0.000001).

Conclusions: Speckle imaging can be successfully used for the assessment of LV volumes and EF. Bull's-eye strain map, created by speckle imaging, can achieve an accurate real-time segmental wall motion analysis.

Rembrandt van Rijn (1606–1669) left behind the largest collection of self-portraits in the history of art. These portraits were painted over a period of 41 years, using a realistic technique. To evaluate Rembrandt's aging process we studied 25 uncontested Rembrandt oil self-portraits by means of objective and descriptive techniques. By measuring brow position changes through the years, we demonstrated that brow descent started in the second half of the third decade and began to level out in the fourth decade. Based on Rembrandts' aging physiognomy, from age 22 to 63, we believe that Rembrandt did not suffer from temporal arteritis, hypothyroidism, rosacea, or rhynophima and that no other facial signs of systemic diseases are evident, contrary to the opinions expressed by other medical professionals. We suggest that Rembrandt suffered from melancholia or mild depression, and propose the possibility of chronic lead poisoning as a theoretical illness that he might have had.

Background: Healthcare behavior occurs within the context of the family unit. Little research has investigated the influences among adult family members regarding their use of medical care services.

Objectives: To investigate the effects of maternal attendance patterns and maternal self-assessed health status on those of adult children.

Methods: This study was a retrospective cohort, analyzing both patient records for physician visits and mailed self-administered questionnaires regarding subjective health assessment. We evaluated a unique study group of multi-generational families with free and equal access to medical services at a primary care kibbutz clinic in Israel. This enabled an exclusive focus on the association between the use of healthcare by mothers and their grown children.

Results: Controlling for the subjects' age, gender and number of chronic diagnoses, a significant association exists between the family physician visit rates of a mother and those of her grown offspring (P = 0.03). Low self-health assessment is associated with higher levels of physician utilization (P = 0.003). Maternal self-health evaluation is associated with her adult children's own self-health evaluation (odds ratio 5.9, P = 0.04) and their rates of physician utilization (one additional offspring visit per year for low maternal self-health, P = 0.02).

Conclusions: A mother’s behavior patterns measured via self-rated health status and physician visit rates serve as a proxy for maternal attitudes regarding healthcare, and these attitudes are possibly imparted to her children for life. This study provides unique evidence for a maternal health behavior effect on grown children, and enables a more complete understanding of families attending the primary care clinic.
 

Objectives: To evaluate factors that might influence the decision of pregnant women to choose chorionic villous sampling for prenatal testing.

Methods: The study group comprised 239 women referred for prenatal diagnosis who elected to undergo CVS[1]. The data were analyzed according to indication, ethnic group and religion.

Results: Among women undergoing CVS because of advanced maternal age and because of anxiety, we noted a significantly high proportion of unbalanced families, i.e., with three or more children of the same gender and deviated gender ratio. We found a significant excess of males among the Jewish families and a significant excess of females among the non-Jewish families. Jews were over-represented in the monogenic group while Christian Arabs were over-represented in the maternal age/anxiety group.

Conclusions: The proportion of women who chose CVS for prenatal diagnosis varied according to indication, ethnic group and religion. The data in this study indicate that CVS may have been utilized for balancing families with ≥ 3 or more children of the same sex. Christian Arabs chose CVS more often than the other groups. Jewish women may have utilized CVS for family balancing of both sexes, while non-Jews may have utilized CVS for balancing families with ≥ 3 daughters.
