Background: Iron deficiency is the most common single cause of anemia worldwide. Treatment consists of improved nutrition along with oral, intramuscular or intravenous iron administration.

Objectives: To describe the efficacy and adverse effects of intravenous iron sucrose therapy in a group of children with iron deficiency anemia who did not respond to oral iron therapy.

Methods: We conducted a prospective investigation of 45 children, aged 11 months to 16 years, whose oral iron therapy had failed. The children attended the Pediatric Ambulatory Care Unit where they received intravenous iron sucrose infusion.

Results: Forty-four of the 45 patients were non-compliant. Nine had Helicobacter pylori gastritis and 16 patients suffered from intestinal malabsorption from different causes. Before treatment, the blood mean hemoglobin concentration was 7.43 g/dl (range 5–10.1 g/dl). Fourteen days after treatment the mean hemoglobin concentration increased to 9.27 g/dl (SD 1.23) and 6 months later to 12.40 g/dl (SD 1.28). One patient demonstrated a severe side effect with temporary and reversible reduced blood pressure during treatment.

Conclusions: These preliminary data suggest that administration of intravenous iron in pediatric patients is well tolerated and has a good clinical result, with minimal adverse reactions.

Background: The patient package insert, an information leaflet included by law in the packaging of prescription drugs, contains information for the user on the specific medication.

Objectives: To explore how patient information leaflets influence patient anxiety and adherence.

Methods: A prospective cohort study was conducted in the practices of 15 family physicians. All patients receiving a new prescription for antibiotics, analgesics or antihypertensives were included. Physicians completed a questionnaire containing demographic data, assessment of the patient’s anxiety, a prediction about adherence to the treatment, and response to the information leaflet. Patients were contacted by telephone for a follow-up structured interview. Patients' reactions to the information leaflet, adherence to treatment, and use of other sources of information on medication were assessed.

Results: The study group comprised 200 patients. The patient information leaflet was read by 103 of them (51.5%). A higher educational level and a chronic medication were associated with reading the leaflet (P = 0.02 and 0.01 respectively). In 36 (34.9%), an increase in anxiety was reported after reading the leaflet. Among those who read the leaflet, 9.7% had decreased adherence. Patients who stated that reading the leaflet caused anxiety were more likely to reduce their use of the medication – 7/36 (19.5%) vs. 3/67 (4.5%), P = 0.01.

Conclusions: The proportion of patients reading the drug information leaflet is about 50%, lower than that found in previous studies. Reading the leaflet did not greatly affect adherence but aroused anxiety and decreased adherence in some patients.

Background: Spontaneous coronary reperfusion occurs in 7–27% of patients with ST elevation myocardial infarction, and is an independent predictor of myocardial salvage, percutaneous coronary intervention success, and improved outcome.

Objectives: To determine the optimal PCI[1] time for patients admitted to the hospital due to STEMI[2] with SCR[3].

Methods: We performed a retrospective analysis of all patients admitted to the coronary care unit between July 2002 and November 2004 with a diagnosis of STEMI with SCR.

Results: The study group comprised 86 patients. There was not a single reinfarction episode during an observation period of 6579 patient hours. Cardiac catheterization was executed early (< 24 hours from pain onset) in 26 patients and late (> 24 hours) in 55. Pre-PCI angiographic TIMI flow 2–3 was seen in > 95% in both groups. PCI was performed more frequently in the “early” group (P = 0.024), while multi-vessel coronary artery disease (P = 0.094) requiring coronary bypass surgery (P = 0.056) was observed more frequently in the “late catheterization” group. Myocardial infarction and angina pectoris at 30 days occurred more frequently in the early catheterization group (P = 0.039), however no difference in any major adverse cardiac events was detected during long-term follow-up (491 ± 245 days).

Conclusions: Reinfarction after STEMI with SCR is a rare event. Early PCI in patients with STEMI and SCR, even when executed with aggressive anti-platelet therapy, seems to result in an excess of early MACE, without any long-term advantage. Prospective randomized trials should determine the optimal PCI timing for these patients.

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.

 Background: External counter-pulsation is a safe and effective method of alleviating angina pectoris, but the mechanism of benefit is not understood.

Objectives: To evaluate the safety and efficacy of external counter-pulsation therapy in heart failure patients.

Methods: Fifteen symptomatic heart failure patients (subsequent to optimal medical and device therapy) underwent 35 hourly sessions of ECPT[1] over a 7 week period. Before and after each ECPT session we performed pro-B-type natriuretic peptide and brachial artery function studies, administered a quality of life questionnaire, and assessed exercise tolerance and functional class.

Results: Baseline left ventricular ejection fraction was 28.1 ± 5.8%. ECPT was safe and well tolerated and resulted in a reduction in pro-BNP[2] levels (from 2245 ± 2149 pcg/ml to 1558 ± 1206 pcg/ml, P = 0.022). Exercise duration (Naughton protocol) improved (from 720 ± 389 to 893 ± 436 seconds, P = 0.0001), along with functional class (2.63 ± 0.6 vs. 1.93 ± 0.7, P = 0.023) and quality of life scores (54 ± 22 vs. 67 ± 23, P = 0.001). Nitroglycerine-mediated brachial vasodilatation increased (11.5 ± 7.3% vs. 15.6 ± 5.2%, P =0.049), as did brachial flow-mediated dilation (8.35 ± 6.0% vs. 11.37 ± 4.9%, P = 0.09).

Conclusions: ECPT is safe for symptomatic heart failure patients and is associated with functional and neurohormonal improvement. Larger long-term randomized studies with a control arm are needed to confirm these initial encouraging observations.

 Background: Previous assessments of maternal group B Streptococcus carrier rates in women delivering at Shaare Zedek Medical Center ranged between 3.5 and 11% with neonatal sepsis rates of 0.2–0.9/1000 live births. Because of low colonization and disease rates, routine prenatal cultures of GBS[1] were not recommended, and intrapartum prophylaxis was mainly based on maternal risk factors.

Objectives: To determine whether this policy is still applicable. 

Methods: We performed prospective sampling and follow-up of women admitted for labor and delivery between February 2002 and July 2002. Vaginal and rectal cultures were obtained before the first pelvic examination. GBS isolation was performed using selective broth medium, and identified by latex agglutination and serotyping. Demographic data were collected by means of a standardized questionnaire. Data on the newborns were collected throughout 2002.

Results: Of the 629 sampled women, 86 had a positive culture and a carrier rate of 13.7%. A borderline significantly higher carriage rate was observed among mothers of North American origin (21% vs. 13.1%, P = 0.048), and a higher attack rate in their infants (3.8/1000 compared with 0.5/1000 live births in our general maternal population, P = 0.002). Eight newborns had early-onset neonatal GBS sepsis (a rate of 0.8/1000 live births), but none of them benefited from intrapartum antibiotic prophylaxis.

Conclusions: An increased neonatal disease rate was observed in a population with a higher colonization rate than previously seen. In lieu of the higher carrier rates, we now recommend routine prenatal screening for GBS in our perinatal population.

Background: The cause of cerebral palsy remains unknown in most cases. Factor V Leiden mutation, a common cause of hereditary thrombophilia, has been associated with CP[1].

Objectives: To analyze the prevalence of factor V Leiden (G1691A), prothrombin (G20210A), and methylenetetrahydrofolate reductase (C677T) mutations in children with CP.

Methods: Sixty-one children with CP were studied for the presence of the three gene mutations associated with thrombophilia.

Results: We found that 41% of the children with CP and 33% of the controls carry one or more of the studied mutations (P = 0.348). The prevalence of the factor V mutation was 27.9% in CP and 16.4% in controls (P = 0.127). The frequency of the other two genetic factors was even less significant. The FVL[2] mutation was found in 35% of the Arab CP patients (15/42) and in 22% of the controls from the same population (9/40) (P = 0.067).

Conclusions: Each of the genetic factors studied was shown to be related to CP. Despite the high frequency of FVL among the studied patients, we were unable to prove a significant correlation between FVL and CP, mainly because this factor is frequent in the Arab control group. In this population a trend toward significance can be seen (P = 0.067). Larger studies are needed to validate the significance of these results.

 Background: Coronary sinus is a venous conduit with dynamic and unclear function with regard to coronary circulation.  

Objectives: To describe the dynamic changes of the coronary sinus during the cardiac cycle.

Methods: The angiographic feature of the coronary sinus was evaluated in 30 patients undergoing diagnostic and therapeutic coronary angiography.

Results: Prolonged angiographic imaging following coronary injections permitted accurate demonstration of the coronary sinus in all 30 patients. We report, for the first time, that the coronary sinus can be divided into two angiographic functional/anatomic portions, upper and lower. The lower part is prone to a highly dynamic contraction/relaxation pattern, observed in 12 of the 30 patients, while 10 patients had normal and 8 had low contractile pattern on angiography. Clinical assessment of these patients did not identify an association with this motion pattern.

Conclusions: The coronary sinus is an important anatomic/functional structure that should be further investigated in patients with various forms of heart disease.
