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: Obesity has become a major public health problem worldwide.

Objectives: To examine the effect of orlistat in promoting weight loss and its specific effect on the visceral adipose tissue and subcutaneous adipose tissue as evaluated by computed tomography.

Methods: A prospective case series study of 10 obese subjects was conducted. The 6 women and 4 men, age 50–67 years (mean 59 ± 8 years), had a mean body mass index of 34.1 ± 3.2 kg/m². All subjects were prescribed a mildly hypocaloric diet (600 kcal/day deficit). In addition, all subjects were treated with orlistat 120 mg 3 times a day for 20.1 ± 7 weeks.

Results: The subjects had lost approximately 8.2 kg each, or 8.4% of their initial body weight. Mean body weight decreased from 98 ± 13 to 89.8 ± 13.6 kg at the last follow-up visit (P = 0.0001) mean BMI[1] decreased from 34.1 ± 3.2 to 30.3 ± 3.9 kg/m² (P = 0.0001), and mean waist circumference from 113.8 ± 11.4 to 107.6 ± 10 cm (P = 0.0006). Mean total abdominal adipose tissue volume, evaluated by computed tomography, decreased from 426 ± 104.3 to 369.8 ± 99.6 mm³ (P = 0.0001). Mean abdominal SAT[2] volume decreased from 251.1 ± 78.8 to 224 ± 81.1 mm³ (P = 0.006), and mean abdominal VAT[3] volume decreased from 176 ± 76.7 to 141.6 ± 67 mm³ (P = 0.0001). Thus, the total abdominal adipose tissue volume for the whole group decreased by 15.4%, and most of this decrease was attributable to the reduction in VAT (24.8%) as opposed to SAT (only 12% reduction) (P = 0.03). The weight reduction that occurred during the study was accompanied by a statistically significant reduction in levels of total cholesterol, low density lipoprotein-cholesterol, triglycerides, and fasting blood glucose.

Conclusions: Our results demonstrate the effect of orlistat in reducing human visceral adipose tissue as evaluated by CT. The benefit of the treatment is further supported by the statistically significant reduction in cardiovascular risk factors.

Background: Pathologic breast conditions are rare in childhood and adolescence. The spectrum of breast disease in the pediatric age group is different from that in adults, and most lesions are benign

Objectives: To describe the causes and characteristics of breast asymmetry in adolescents with normal endocrine profiles and sexual development.

Methods: The files of patients with a diagnosis of breast asymmetry referred to a tertiary pediatric center from 1990 to 2007 were reviewed for history and findings on physical examination with or without imaging, treatment and outcome.

Results: Eleven patients aged 12.5 to 18 years were identified. The cause of the breast asymmetry was traced to unpreventable medical factors in eight patients (physiologic, Poland anomaly, scleroderma), preventable/iatrogenic factors in two patients (chest tissue biopsy, thoracic drain), and possible combined medical-iatrogenic factors in one patient (scoliosis treated by a body brace). All patients were referred for breast reconstruction after full breast development.

Conclusions: Severe breast asymmetry in adolescence may be due to congenital factors, diseases involving the breast tissue, or to the effects of medical treatment, and may have severe adverse psychological and social implications. To prevent iatrogenic breast asymmetry, physicians should be made aware of the sensitivity of the breast tissue and should avoid unnecessary tests/procedures that involve the chest wall. In most cases a precise medical history and physical examination can differentiate between physiologic and non-physiologic causes.

Background: Interleukin-10 is an anti-inflammatory cytokine and consequently is considered by many to have a protective role in heart failure, as opposed to the notorious tumor necrosis factor-alpha.

Objectives: To test the hypothesis of the possible beneficial impact of IL-10[1] on mortality in systolic heart failure patients in relation to their circulating TNFα[2] levels.

Methods: We measured circulating levels of IL-10 and TNFα in 67 ambulatory systolic heart failure patients (age 65 ± 13 years).

Results: Mortality was or tended to be higher in patients with higher levels (above median level) of circulating TNFα (9/23, 39% vs. 6/44, 14%; P = 0.02) or IL-10 (10/34, 30% vs. 5/33, 15%; P = 0.10). However, mortality was highest in the subset of patients with elevation of both markers above median (7/16, 44% vs. 8/51, 16%; P = 0.019). Elevation of both markers was associated with more than a threefold hazard ratio for mortality (HR[3] 3.67, 95% confidence interval 1.14–11.78).

Conclusions: Elevated circulating IL-10 levels in systolic heart failure patients do not have a protective counterbalance effect on mortality. Moreover, patients with elevated IL-10 and TNFα had significantly higher mortality, suggesting that the possible interaction in the complex inflammatory and anti-inflammatory network may need further study.

Background: Most data on the incidence of rheumatic fever come from hospital records. We presumed that there may be cases of RF[1] that do not require hospitalization, especially in countries with high quality community health care. 

Objectives: To explore the incidence and characteristics of RF using community-based data. 

Methods: A retrospective descriptive study was conducted among the members (more than 450,000) of the Clalit Health Services, Central district, during 2000–2005. The electronic medical files of members up to 40 years old with a diagnosis of RF in hospital discharge letters or during community clinic visits were retrieved. Patients with a first episode of RF according to the modified Jones criteria were included.

Results: There were 44 patients with a first episode of RF. All patients were under the age of 29. The annual incidence among patients aged 0–30 years was 3.2:100,000; the highest incidence was among children aged 5–14 years (7.5:100,000), and in males the incidence was 2.26 times higher than in females. The incidence was higher among patients from large families, of non-Jewish ethnicity, and from rural areas. Twenty-five percent of the patients were both diagnosed and treated in an ambulatory care setting.

Conclusions: Although the incidence of RF in the western world and in Israel is low, the disease still occurs and mainly affects children. Any future estimates of disease incidence should take into account that RF is becoming an ambulatorily treated disease.  

Background: Severe hearing impairment can have devastating effects on social integration and vocational opportunities.

Objectives: To investigate how well – or poorly – individuals who underwent cochlear implantation as children integrated into the general Israeli hearing community.

Method: We sent a questionnaire to the 30 subjects ≥ 18 years old who underwent cochlear implants our department from 1990 to 2004 when they were < 18 years of age and had used their device for at least 3 years before replying.

Results: Eighteen implant users responded (14 males), yielding a 60% response rate. Their mean age was 13.3 ± 7.0 years (range 6–17) at implantation and 21.1 ± 3.6 years (range 18–34) when they filled in the questionnaire. Five were attending rabbinical school (yeshiva students), four were in regular military service, five were university students (three also held jobs), two were attending high school, one was employed (and had a university degree), and one had left the yeshiva and was unemployed when he returned the questionnaire. Fourteen respondents use the oral communication mode for conversation and the other 4 use both oral and sign languages. Longer daily implant use was significantly associated with coping with the difficulties in the setting in which they were currently active, with a higher level of satisfaction with their current lifestyle and with recognition of the implant’s contribution to this satisfaction (P = 0.037, P = 0.019 and P = 0.001, respectively).

Conclusions: Advances in cochlear implant technologies enable profoundly deaf implanted children to integrate well into the Israeli hearing society, albeit with a large inter-subject variability.

Background: Cancer is a leading cause of mortality worldwide. The most effective way to combat cancer is by prevention and early detection.

Objectives: To evaluate the outcome of screening an asymptomatic population for the presence of benign and neoplastic lesions.

Methods: Routine screening tests for prevention and/or early detection of 11 common cancers were conducted in 300 consecutive asymptomatic, apparently healthy adults, aged 25–77 years. Other tests were performed as indicated.

Results: Malignant and benign lesions were found in 3.3% and 5% of the screenees, respectively, compared to 1.7% in the general population. The most common lesions were in the gastrointestinal tract followed by skin, urogenital tract and breast. Advanced age and a family history of a malignancy were associated with increased risk for cancer with an odds ratio of 9 and 3.5, respectively (95% confidence interval 1.1–71 and 0.9–13, respectively). Moreover, high serum C-reactive protein levels and polymorphisms in the APC and CD24 genes indicated high cancer risk. When two of the polymorphisms existed in an individual, the risk for a malignant lesion was extremely high (23.1%; OR[1] 14, 95% CI[2] 2.5–78).

Conclusions: Screening asymptomatic subjects identifies a significant number of neoplastic lesions at an early stage. Incorporating data on genetic polymorphisms in the APC and CD24 genes can further identify individuals who are at increased risk for cancer. Cancer can be prevented and/or diagnosed at an early stage using the screening facilities of a multidisciplinary outpatient clinic.

Background: The incidence of congenital heart defects, reported to be 5–8/1000 in term infants, is not well established in very low birth weight infants.

Objectives: To establish the incidence of congenital heart defects in VLBW[1] infants in the neonatal intensive care unit of our institution.

Methods: A retrospective analysis of the population in the NICU[2] at our institution was performed. VLBW (BW ≤ 1500 g) infants born between 2001 and 2006 who survived more than 48 hours were included in the study. Infants with clinical signs of heart disease underwent echocardiography.

Results: During the study period 437 VLBW live-born infants met the inclusion criteria. Of these, 281 (64.3 %) underwent echocardiography. CHD[3] was detected in 19 infants (4.4%, 95% confidence interval 2.4–5.4%), significantly higher than the incidence of 5–8/1000 in the general population (P < 0.0001). In the subgroup of 154 infants with BW < 1000 g there were 10 (6.5%) with CHD. In the subgroup of 283 infants with BW 100–-1500 g there were 9 (3.2 %, P = 0.19 vs. VLBW) with CHD.

Conclusions:  Our observations show an increased incidence of CHD in VLBW neonates, as compared to the general population. Since not all infants underwent echocardiography, and minor cardiac defects may have been missed in our VLBW infants, the true incidence may be higher than reported here.
