Objectives: To determine whether children with multiple siblings are at increased risk for accidents, to assess whether quality of child supervision varies with family size, and to evaluate the relationship of family size with the rapidity of seeking medical care after an accident.

Methods: We prospectively studied 333 childhood accidents treated at TEREM (emergency care station) or Shaare Zedek Medical Center. Details on family composition and the accident were obtained through parental interview. Family size of the study population was compared with that of the Jerusalem population. Families with one to three children (Group 1) and four or more children (Group 2) were compared with regard to type of supervision and different "Gap times" – the time interval from when the accident occurred until medical assistance was sought ("Gap 1"), the time from that medical contact until arrival at Shaare Zedek ("Gap 2"), and the time from the accident until arrival at Shaare Zedek for those children for whom interim medical assistance either was ("Gap 3A") or was not ("Gap 3B") sought.

Results: Children from families with 1, 2, 3, 4 and ≥5 children comprised 7.2%, 18.3%, 14.4%, 18.6% and 41.4% of our sample compared to 20.4%, 21.8%, 18.4%, 14.7% and 24.7% in the general population respectively. Children from Group 2 were less often attended to by an adult (44.5% vs. 62.0%) and more often were in the presence only of other children at the time of the accident (27.0% vs. 10.5%). Gaps 1, 2 and 3A in Group 2 (6.3 hours, 16.5 hours, 27.8 hours respectively) were longer than for Group 1 (2.7, 10.7, 13.3 hours respectively).

Conclusions: The risk for accidents is increased among children from families with four or more children. The adequacy of child supervision in large families is impaired. There is a relative delay from the time of the accident until these children are brought for treatment. 

Objectives: To review the current status of MAS[1] in a pediatric tertiary care center in Israel, in terms of feasibility, safety, and effect on standard practices.

Methods: We reviewed the files of all children who underwent a MAS procedure in our department during the period April 2002 to July 2004, and compared the findings with those of children treated by standard practices.

Results: A total of 301 procedures were performed in 271 patients: 107 thoracoscopic and 194 laparoscopic. There were no major intraoperative complications. The total conversion rate was 3.65%: 0 for thoracoscopy and 5.6% for laparoscopy (11/194). Twenty-four types of procedures were performed during the study period. The thoracoscopies accounted for 92.24% of all thoracic procedures in the department (107/116), and routine abdominal laparoscopic procedures replaced open surgery in 30–100% of cases (total 44.8%, 194/433).

Conclusions: MAS procedures appear to be safe for a wide range of indications in children. In our center they currently account for a significant percentage of pediatric surgeries. We suggest that the integration of MAS training in the residency programs of pediatric surgeons be made a major long-term goal. The creation of a pediatric MAS study group, which would allow for multi-institutional studies, is especially important in Israel where a relatively large number of pediatric surgery departments handle a small annual number of patients.

Objectives: To provide data on fatal traumatic heart wounds in autopsied cases.

Methods: We reviewed 2,487 medico-legal autopsy records of the morgue department of the Bursa branch of the Turkish Council of Forensic Medicine for the period 1997–2001.

Results: Of these cases, 160 (6.4%) had cardiac injury; 13.8% were females and 86.2% males, and the mean age was 35.9 years old (range 4–65). The most common cause of heart wounds was penetrating trauma (87.5%), namely sharp injuries (48.1%) and firearm injuries (39.4%). The two most common causes of blunt heart wounds were traffic accidents (5.6%) and falls from a height (5%). Rupture was present in 96.9% of the cases, and isolated left ventricle and isolated right ventricle were ruptured in 31.3% and 23.8%, respectively. In penetrating injury the risk of ventricle rupture was higher than of atrium rupture. Alcohol was detected in 16.3% of cases. Only 3.5% of the penetrating cardiac injury cases and 5% of the blunt cardiac injury cases were admitted to hospital.

Conclusions: Given that only a very low percentage of the patients who sustain cardiac injury reach hospital alive, population-based studies, especially autopsy results, should be conducted to define the characteristics of cardiac injuries.

Objectives: To determine the prevalence of abnormal coagulation studies in ED[1] patients evaluated for suspected ACS[2], and to investigate whether abnormal international normalized ratio/partial thromboplastin time testing resulted in changes in patient management and whether abnormal results could be predicted by history and physical examination.

Methods: In this retrospective observational study, hospital and ED records were obtained for all patients with a diagnosis of ACS seen in the ED during a 3 month period. ED records were reviewed to identify all patients in whom the cardiac laboratory panel was performed. Other data included demographics, diagnosis and disposition, historical risk factors for abnormalities of coagulation, ED and inpatient management, INR[3]/PTT[4], platelet count and cardiac enzymes. Descriptive statistical analyses were performed.

Results: Complete data were available for 223 of the 227 patients (98.7%). Of these, 175 (78.5%) patients were admitted. The mean age was 64.2 years. Thirteen patients (5.8%) were diagnosed with acute myocardial infarction. Of the 223 patients, 29 (13%) and 23 (10%) had INR and PTT results respectively beyond the reference range. Seventy percent of patients with abnormal coagulation test results had risk factors for coagulation disorders. The abnormal results of the remaining patients included only a mild elevation and therefore no change in management was initiated.

Conclusions: Abnormal coagulation test results in patients presenting with suspected ACS are rare, they can usually be predicted by history, and they rarely affect management. Routine coagulation studies are not indicated in these patients.

Objective: To determine breast-feeding patterns and the association between sociodemographic characteristics and breast-feeding in the Tel Aviv district.

Methods: The mothers of infants aged 2, 4, 6 and 12 months, attending 59 well-baby clinics in the Tel Aviv district, were interviewed by telephone. Singleton infants who weighed less than 2,000 g and multiple-gestation infants were excluded from the study. The questions covered background data, sociodemographic characteristics of the family, and breast-feeding practices. Stepwise logistic regression was used to analyze the association between breast-feeding and various sociodemographic characteristics.

Results: Altogether, 78.5% of the mothers (1,307/1,665) initiated breast-feeding. The rate of breast-feeding at 2, 4, 6 and 12 months was 55.8, 36.8, 29.9 and 11.8%, respectively. Only 35.8% of the infants at 2 months and 11.2% at 6 months were exclusively breast-fed. The mean duration of breast-feeding was 5.2 ± 0.2 months. Grand multiparas (≥5 children) had a significantly higher rate of breast-feeding than women with one to four children (P < 0.001). More likely to breast-feed for 2 weeks or longer were women married to Yeshiva students (odds ratio = 5.3), women with ≥13 years education (OR[1] = 2.1), and women on maternity leave (OR = 1.6). The predictors for breast-feeding for 6 months or longer were similar.

Conclusions: Although the rate of breast-feeding initiation in central Israel was 78.5%, only 29.9% of the mothers continue to breast-feed for 6 months. Already at a young age, an appreciable number of breast-fed infants receive infant formula. Breast-feeding promotion should focus on less educated women, homemakers, and families with one to four children.

Objectives: To evaluate the accuracy of 16-slice multi-detector CT angiography in the diagnosis of coronary artery disease, and assess coronary bypass grafts and coronary anomalies.

Methods: We conducted a retrospective study of 223 patients who were examined at our medical center over a period of 2 years with a 16-slice CT angiography scanner and retrospective electrocardiographic gating.

Results: There were no significant complications, and good visualization of the coronary arteries was achieved in all but eight patients. A high correlation with the results of the invasive angiography was noted (sensitivity 85%, specificity 93%, negative predictive value 98%). Altogether, 131 bypass conduits were examined with excellent graft visualization. Several coronary anomalies were detected, as were significant extra-cardiac findings.

Conclusions: Multi-slice CT angiography is a reliable non-invasive diagnostic procedure for demonstration of the coronary arteries and bypass grafts. In the future it will probably replace part of the diagnostic invasive coronary angiography and, as a result, a large proportion of coronary angiography procedures will be therapeutic.

Objectives: To investigate the time relation between the insertion of a new NGT and formation of the biofilm.

Methods: We examined sequential samples on NGTs that were forcibly pulled out by the patients themselves during any of the 7 days after insertion. Scanning electron micrography and confocal laser scanning microscopy were used for biofilm detection.

Results: Biofilm was identified on 60% of the 35 samples of day 1 and on all the samples of the following days, by both microscopic methods.

Conclusions: Biofilms form within a single day on most NGTs inserted for the feeding of elderly patients with dysphagia. Further research should be devoted to prevention of biofilm formation on NGTs.
