Immunization coverage is a major health indicator. In Israel, routine childhood immunizations are provided at community public well-baby clinics. Immunization monitoring is an important cornerstone of a national health policy however, data obtained through sampling carries the risk of under-representation of certain population strata, particularly high risk groups. Despite high national average immunization coverage, specific sub-populations are under-immunized, as highlighted by outbreaks of vaccine-preventable diseases. The mean national immunization coverage at age 2 years (2006 data) was: DTaP[1]-IPV[2]-Hib4[3] (all 93%), HBV[4]3 (96%), MMR1[5] (94%), HAV1[6] (90%). These reports are based on a 17% population-based sample in some districts and on cumulative reports in others. A national immunization registry requires data completeness, protection of confidentiality, compulsory reporting by providers, and links to other computerized health records. It should provide individual immunization data from infancy to adulthood and be accessible to both providers and consumers. In 2008 the Israel Ministry of Health launched a national immunization registry based on immunization reporting from well-baby clinics using a web-based computerized system. As of January 2010, 120 well-baby clinics are connected to the nascent registry, which includes the records of some 50,000 children. The implementation of a comprehensive national immunization registry augurs well for the prospect of evidence-based assessment of the health status of children in Israel.

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: Ritual circumcision in neonates may cause a urinary tract infection within 2 weeks of the procedure.

Objectives: To evaluate the prevalence of urinary tract infection among Jewish male circumcised neonates (¡Ü 28 days old) evaluated for fever in the emergency room.

Methods: All available medical records of neonates presenting to the pediatric emergency room for evaluation of fever over a 10 year period were reviewed. Data included gender, ethnic background, age in days on presentation to the emergency room, age in days when circumcision was performed (in males ¡Ý 8 days of age), and results of urine, blood and cerebrospinal fluid cultures. Families of males older than 8 days of age who had a UTI[1] were contacted by telephone to verify the circumcision status when the infant presented to the ER[2], to ascertain whether the circumcision was performed ritually by a mohel* or by a physician, and, when not recorded in the chart, to verify the day of life on which circumcision was performed.

Results: Among neonates older than 8 days of age, 60 (24.7%) of the 243 febrile Jewish males had a UTI, as compared to 12 (8.4%) of 143 females (P < 0.0001). In 39 of 54 male neonates (72%) for whom circumcision was performed ritually on the eighth day of life, UTI occurred within 9 days of the circumcision. For females, there was no such clustering of UTI cases in the second week of life, nor during any other time period.

Conclusions: Febrile male neonates who have undergone ritual circumcision have a high prevalence of UTI and must be evaluated and treated accordingly.

Background: The best therapeutic alternative for patients suffering from in-stent restenosis after drug-eluting stent implantation remains to be elucidated.

Objective: To characterize the pattern, treatment and outcomes of DES[1]-related in-stent restenosis in patients treated at our institution.

Methods: We determined the incidence and major adverse clinical events in 71 consecutive patients with DES failure among 2473 patients who were treated with 2548 drug-eluting stents between 2004 and 2007. We analyzed the clinical data, procedural parameters and clinical outcomes.

Results: The type and number of stents implanted were as follows: Cypher (n=1808), Endeavor (421) and Taxus (319) of these, 53 (2.9%), 10 (2.4%), and 8 (2.5%) patients respectively presented with restenosis. The mean time to restenosis was 11.3 ± 9.9 months. Patients’ mean age was 65 ± 11 years 75% were male, and 68% had diabetes mellitus. Unstable angina was the clinical presentation in 52 (73%). At 6 months, 3 patients had developed myocardial infarction (4.2%), repeat restenosis at follow-up was diagnosed in 8 patients (11.3%), the overall major adverse clinical events rate was 18.3% (13 patients), and 2 patients died (2.8%).

Conclusions: Drug-eluting stent-related restenosis is relatively infrequent but remains a clinical challenge. It occurs more frequently in complex lesion subsets, but the overall intermediate-term prognosis is tolerable.

Background: Obstruction of urine outflow can result from mechanical blockade as well as from functional defects. In adults, urinary tract obstruction is due mainly to acquired defects, such as pelvic tumors, calculi, and urethral stricture. In childhood it is mostly due to congenital malformations. In this article we present two rare cases of acute obstructive renal failure that presented with hydronephrosis. These cases underline the wide range of causes that may lead to this clinical feature. 

Background: Normal-tension glaucoma is a chronic progressive optic neuropathy of unknown etiology. Neuroimaging workup in these patients is controversial.

Objectives: To determine the value of routine neurologic and neuro-ophthalmologic evaluations in patients with NTG[1].

Methods: We conducted a retrospective review of all patients diagnosed with NTG in our institution between 2001 and 2006. Neurologic and neuro-ophthalmologic data were evaluated.

Results: Sixty-eight patients were considered suitable for the study (35 males, 33 females age range 43–90 years). Neurologic and neuro-ophthalmologic findings were normal in all of them. The computed tomography brain scan was normal in 88% and duplex carotid Doppler scan was normal in 92%.

Conclusions: Pathologic findings in neurologic and neuro-ophthalmologic assessments were uncommon in NTG. Therefore, contrary to earlier suggestions, neurologic and neuro-ophthalmologic evaluations in typical normal-tension glaucoma patients appear to have no added value.

Background: The prognostic significance of biologic markers in women with ductal carcinoma in situ is not fully understood. HER2/neu is a marker of prognostic significance that is routinely assessed in invasive cancer but its correlation with clinical outcome in DCIS[1] is still obscure.

Objectives: To evaluate the significance of HER-2/neu expression as a prognostic marker in DCIS.

Methods: Clinical and pathologic data from 84 patients treated for DCIS were analyzed. HER-2/neu expression was determined by immunohistochemical staining. Histopathologic parameters (nuclear grade, histologic subtype, necrosis, calcifications, margins) were reviewed by an experienced pathologist. Local recurrence and/or metastatic spread were used as endpoints to determine the prognostic significance of HER-2/neu expression.

Results: With a median follow-up of 94.8 months, nine recurrences were reported. Neither univariate nor multivariate analysis showed a significant correlation between HER-2/neu expression and disease recurrence or the time to disease recurrence. Although HER-2/neu expression demonstrated a significant association with high nuclear grade (P < 0.0001) and comedo subtype (P < 0.0001), there was no correlation between these histologic features and recurrence rate. The correlation between high nuclear grade and disease recurrence approached statistical significance (P = 0.07).

Conclusions: No significant association was found between HER-2/neu expression in DCIS and disease recurrence. However, HER-2/neu correlated with negative markers such as nuclear grading and comedo necrosis, and its role should therefore be investigated in larger studies.
