Cesarean delivery on maternal request in Israel: Maternity department policies and obstetricians' perspectives.

OBJECTIVE: This study aimed to describe Israeli maternity departments' policies regarding cesarean delivery on maternal request, and factors associated with obstetricians' support for cesarean delivery on maternal request in specific scenarios. METHODS: This multicenter cross-sectional study included 22 maternity department directors and 222 obstetricians from the majority of Israeli hospitals. Directors were interviewed and completed a questionnaire about their department's cesarean delivery on maternal request policy, and obstetricians responded to a survey presenting case scenarios in which women requested cesarean delivery on maternal request. The scenarios represented profiles referring to the following factors: maternal age, poor obstetric history, pregnancy complications, and psychological problems. The survey also included the obstetricians' socio-demographic information and questions about other issues associated with cesarean delivery on maternal request. The main outcome measures were department policies regarding cesarean delivery on maternal request and obstetricians' support for cesarean delivery on maternal request in specific cases. RESULTS: Policies were divided between allowing and prohibiting cesarean delivery on maternal request (n = 10 and 12, respectively), and varied regarding issues such as informed consent and pre-surgery consultation. Most of the obstetricians (96.5%) did not support cesarean delivery on maternal request in the "reference scenario" describing a young woman with no obstetric complications. Additional factors increased the rate of support. Support was greater among obstetricians aged > 45 (odds ratio = 2.11; 95% confidence intervals 1.33-3.36) and lower among females (odds ratio = 0.58; 95% confidence intervals 0.39-0.86). Obstetricians whose department policy was less likely to allow cesarean delivery on maternal request reported lower rates of support for cesarean delivery on maternal request in most cases. CONCLUSION: Policies and obstetricians' support for cesarean delivery on maternal request vary broadly depending on clinical profiles and physician characteristics. Department policy has an impact on obstetricians' support for cesarean delivery on maternal request. Health policy will benefit from a framework in which the organizations, physicians, and patients are consulted.

Missed initial appointments at Israeli child development centres: Rate, reasons, and associated characteristics.

INTRODUCTION: Missed appointments (MAs) at child development centres (ChDCs) cause multiple problems: they preclude timely diagnosis and treatment of both the invited child and children whose appointment was delayed due to overbooking, as well as disrupting efficient organisational management. The aim of this study was to assess the rate and describe the reasons for missed appointments at Israeli ChDCs, and to evaluate the association of socio-demographic, clinical, and administrative variables with MA rates. METHODS: This nested case-control study included all children scheduled for initial appointments (N = 1143) at three centres during 1 year. Parents of children who missed their appointment and a sample of those who attended were interviewed by telephone. RESULTS: The rate of missed appointments was 26.6%, and the most frequent reasons were unexpected events (26.0%) and lack of insurance coverage (23.4%). Variables associated with lower MA rates were: having had ≥3 types of rehabilitative interventions (odds ratios (OR) = 0.26; 95% confidence interval [CI] 0.16-0.44), detailed referral letter (OR = 0.48; 95%CI 0.30-0.75), telephone reminder (OR = 0.37; 95%CI 0.24-0.57) and health maintenance organisations or private insurance coverage (OR = 0.12; 95%CI 0.06-0.17 and OR = 0.56; 95% CI 0.38-0.89, respectively). CONCLUSION: Encouraging physician's referral letters and personal-contact reminders can reduce missed appointments. Understanding the family's and the child's personal characteristics, and the organisational/administrative aspects of missed appointments may guide efforts to ensure timely care for every child.

Obstetric and Neonatal Outcomes following COVID-19 Vaccination in Pregnancy.

COVID-19 infection imposes a risk for pregnant individuals and may lead to adverse maternal and obstetric outcomes. This is a retrospective cohort study of all women giving birth between March and July 2021 at a single tertiary center. Obstetric and neonatal outcomes were compared between vaccinated and non-vaccinated pregnant women with singleton pregnancies. Women with prior COVID-19 infection, multiple gestations and stillbirth were excluded from the study. Of 4708 women who delivered during the study period, 3700 met the eligibility criteria, of whom 3240 were vaccinated during pregnancy. Compared with the non-vaccinated group, the vaccinated group was characterized by a lower rate of smoking (3.70% vs. 6.67%, p = 0.0028), whereasother maternal characteristics were not significantly different. Multivariable analysis demonstrated that COVID-19 mRNA vaccination was not significantly associated with increased risk of preterm birth as well as other adverse obstetric outcomes including hypertensive diseases of pregnancy, cesarean delivery and small for gestational age. However, a significantly lower risk for meconium-stained amniotic fluid was observed among the vaccinated group (adjusted odds ratio 0.63; 95% confidence interval, 0.46-0.86, p = 0.0039). Moreover, the vaccine was not significantly associated with increased risk of neonatal adverse outcomes including respiratory complications and NICU hospitalization. In conclusion, BNT162b2 messenger RNA vaccination during pregnancy was not associated with an increased rate of adverse obstetric and neonatal outcomes. Therefore, in view of its safety on one hand, and the risk associated with COVID-19 disease in pregnancy on the other hand, BNT 162b2 COVID-19 vaccine should be recommended for pregnant women.

Oncology Treatments during the COVID-19 Pandemic in Israel: the ONCOR Study.

BACKGROUND: The increased susceptibility of cancer patients to coronavirus disease-2019 (COVID-19) infections and complications calls for special precautions while treating cancer patients during COVID-19 pandemics. Thus, oncology departments have had to implement a wide array of prevention measures. OBJECTIVES: To address issues associated with cancer care during the COVID-19 pandemic and to assess the implementation of measures aimed at containment of COVID-19 diffusion while allowing continuation of quality cancer care. METHODS: A national survey among oncology departments in Israel was conducted between 12 April 2020 and 14 April 2020. Eighteen heads of hospital-based oncology departments completed a self-report questionnaire regarding their institute's preparedness for treatment of cancer patients during the COVID-19 pandemic. RESULTS: In this national survey, prevention measures against COVID-19 spread were taken prior to patients' arrival and at arrival or while staying in the departments. Most participants (78-89%) reported using a quick triage of patients and caregivers prior to their entrance to the oncology units, limiting the entrance of caregivers, and reducing unnecessary visits to the clinic. Switching to oral therapies rather than intravenous ones when possible was considered by 82% and shortage in personal protective equipment was reported by five (28%) heads of oncology departments. Some differences between large and small/medium sized medical centers were observed regarding issues related to COVID-19 containment measures and changes in treatment. CONCLUSIONS: Oncology departments in Israel were able to prepare and adapt their services to guidelines and requirements related to the COVID-19 pandemic with little harm to their treatment capacity.

Cognitive achievements in school-age children born following assisted reproductive technology treatments: A prospective study.

BACKGROUND: While assisted reproductive technology is increasingly prevalent, there is concern amid conflicting findings reported regarding the long-term outcomes of children born following these treatments. The aim of this research was to investigate aspects of cognitive development in early school-age Israeli children born following assisted reproductive technology (ART) treatments, compared to those spontaneously conceived (SC). METHOD: This prospective follow-up study was based on an Israeli cohort recruited from June 2006 to December 2008, that included 561 women whose pregnancies were achieved by ART treatments and 600 women whose pregnancies were SC. When the children were 7-8 years old, 759 of their mothers were interviewed by telephone, and 294 were came for developmental assessment. The examination included: Kaufman Brief Intelligence Test; Kaufman Assessment Battery for Children (arithmetic only); Test of Everyday Attention for Children; Beery-Buktenica Developmental Test of Visual-Motor Integration and Supplemental Test for Visual Perception; Rey-Osterrieth Complex Figure Test; Aleph-ad-Tav Hebrew reading and writing; Tavor Picture Naming Expressive Vocabulary Test. Multivariable analyses were adjusted for maternal years of education (≤12, 13+) at child's birth and child's sex. RESULTS: Cognitive function, visual-motor ability, attention, and verbal skills of children born after ART treatments were similar to those of SC children, upon both univariate and multivariable analysis. CONCLUSION AND IMPLICATIONS: No significant differences were found between the ART and SC groups on any of the measures examined. This finding offers couples seeking ART treatments improved information regarding child development during the important and formative school years. WHAT THIS PAPER ADDS: Increasing rates of ART treatments arouse concern about long-term outcomes for offspring, and conflicting findings have been reported with respect to the skills necessary to their academic success. This prospective follow-up study compared school-age children born following ART with spontaneously-conceived children. Children were examined by developmental psychologists, and cognitive function, visual-motor, attention, verbal, and performance skills were similar in both groups.

How Are They Doing? Neurodevelopmental Outcomes at School Age of Children Born Following Assisted Reproductive Treatments.

OBJECTIVE: The purpose of this study was to assess major neurodevelopmental aspects of children conceived by assisted reproductive treatments compared to spontaneously conceived children during the early school years. MATERIAL & METHODS: In this follow-up study, mothers of 358 children born following assisted reproductive treatments and 401 spontaneously-conceived children were interviewed by telephone regarding their children's health and development, when the children were 7-8 years old. The main outcomes were maternal responses to 4 questionnaires: Developmental Coordination Disorder Questionnaire, Short Sensory Profile, Autism Spectrum Screening Questionnaire, and the Attention-deficit hyperactive disorder (ADHD) Child Symptom Inventory-4 subscale. Mothers reported diagnoses of ADHD and autism spectrum disorder. RESULTS: No significant differences were found between the groups in Developmental Coordination Disorder Questionnaire or Short Sensory Profile scores upon univariate or multivariable analyses. There was a slightly higher but nonsignificant rate of diagnosed ADHD among children in the assisted reproductive treatment group (9.6% vs 5.5%; P = .18); on multivariable analysis, a nonsignificant increase in ADHD was also found for assisted reproductive treatment children (hazard ratio 1.45, 95% confidence interval 0.81-2.61). Regarding the Child Symptom Inventory-4 criteria for ADHD among the children who had never been diagnosed, there was also a slightly higher but nonsignificant rate among the assisted reproductive treatments compared to spontaneously-conceived children on univariate (2.4% vs 1.8%; P = .50) and multivariable analysis (odds ratio 0.88, 95% confidence interval 0.27-2.86). Autism spectrum disorder diagnosis or Autism Spectrum Screening Questionnaire scores were not significantly different; however, 5 of the 6 children with autism spectrum disorder diagnoses were in the assisted reproductive treatment group. CONCLUSIONS: Neurodevelopmental measures were similar in both groups, although nonconclusive regarding ADHD and autism spectrum disorder risk. These findings contribute to the knowledge regarding long-term assisted reproductive treatment outcomes.

Cancer in IVF patients treated at age 40 years and older: long term follow-up.

RESEARCH QUESTION: Current knowledge of cancer risk among women who undergo IVF is based mainly on studies of women treated in their thirties, frequently with short follow-up periods. Therefore, information about cancer risk among infertile menopausal women is limited. We aimed to evaluate the risk of cancer among IVF patients treated at age 40 years and older, followed up for an extended period. DESIGN: Historical cohort study of all IVF patients treated at the age of 40 years or older at two university-affiliated IVF units in Jerusalem, Israel, between 1994 and 2002. Data were cross-linked with the Israel National Cancer Registry to 2016. Standardized incidence ratios (SIR) and 95% confidence intervals were computed by comparing the observed number of cancer cases with the expected cancer rate in the general Israeli population adjusted for age and year of birth. In addition, Kaplan-Meier analysis was conducted to account for the length of follow-up. RESULTS: A total of 501 patients were included in the analysis, with mean follow-up of 16.7 ± 3.7 years (range 2-22 years). Mean age at first IVF cycle was 42.3 years (±2.1). Mean number of IVF cycles was 3.2 ± 2.6 (range 1-15). Thirty-six women (7.2%) developed invasive cancer, compared with 47.2 expected cases; SIR 0.76 (95% CI 0.53 to 1.06); 22 women were diagnosed with invasive breast cancer, compared with 19.84 expected; SIR 1.11 (95% CI 0.69 to 1.68). CONCLUSIONS: Older women undergoing IVF treatment were not significantly associated with an excess risk of cancer at long-term follow up. Further studies, however, are needed to confirm these findings.

Mobile Phone-Use Habits Among Adolescents: Predictors of Intensive Use.

Concern has been raised regarding the possible effects of mobile phone use on health, especially by children and adolescents. Thus, it is important to evaluate factors affecting their patterns of use. This study aimed to identify determinants of heavy mobile phone use among Israeli adolescents. Data were collected using a self-report questionnaire regarding mobile phone usage, leisure activity, sociodemographics, and opinion regarding mobile phone use. "Heavy use" was defined as >1 hour of daily duration of voice calls, or >50 daily text messages. The survey included 1,688 seventh and ninth graders in eight middle schools. The vast majority (96.1 percent) used the mobile phone for voice calls daily. Girls were heavier users than boys, and ninth graders were heavier users than seventh graders. Among students attending religious schools, the rate of heavy users was lower than among those attending secular schools. About half of the students did not use hands-free devices at least half of the time. Leisure activities were significantly associated with mobile phone use. This study demonstrates that several variables, including sociodemographics and leisure activities, may predict heavy mobile phone use among teenagers. This information can be useful for exposure assessment and for designing intervention programs for reducing radio frequency (RF) radiation exposure.

The effect of body mass index (BMI) and gestational weight gain on adverse obstetrical outcomes in pregnancies following assisted reproductive technology as compared to spontaneously conceived pregnancies.

OBJECTIVE: To compare the effect of pre-pregnancy body mass index (BMI) and inappropriate gestational weight gain (GWG) on adverse obstetrical outcomes among women undergoing assisted reproductive technology (ART) treatments as compared to spontaneously-conceived (SC) pregnancies. METHODS: This prospective cohort study included 1058 pregnant women from two medical centres; 504 women who conceived following ART treatments and 554 who conceived spontaneously. The women were recruited at 8 weeks of gestation and follow-up telephone interviews were conducted 6 weeks after delivery. Obstetrical outcomes included pregnancy hypertension, gestational diabetes (GD), low birth weight (LBW) (<2500g) and small for gestational age (SGA). Multivariate analyses were used to assess the effect of pre-pregnancy BMI and inappropriate GWG on these obstetrical outcomes adjusted for risk factors. RESULTS: The effect of pre-pregnancy BMI and inappropriate GWG on adverse obstetrical outcomes did not differ between ART and SC pregnancies. Pre-pregnancy obesity was found to be associated with increased risk for pregnancy hypertension (OR=2.16; 95%CI 1.16-4.03), GD (OR=2.89; 95%CI 1.61-5.17), caesarian section (OR=1.77; 95%CI 1.10-2.85) and SGA (OR=1.91; 95%CI 1.05-3.46). GWG below recommendations was associated with increased risk for GD (OR=1.73; 95%CI 1.06-2.82) and SGA (OR=1.69; 95%CI 1.17-2.40) while GWG above recommendations was associated with increased risk for pregnancy hypertension (OR=1.77; 95%CI 1.02-3.06). CONCLUSIONS: Pre-pregnancy obesity and inappropriate GWG were associated with adverse obstetrical outcomes in both ART and SC pregnancies. Emphasis should be given on the importance of an optimal pre-pregnancy BMI and appropriate GWG during pregnancy.

When the Ideal Meets the Feasible: Constructing a Protocol for Developmental Assessment at Early School-Age.

Objective: To describe development of a methodology for an outcome study of children born following in-vitro fertilization or spontaneously-conceived, as a model for defining normal and below-normal development of school-age children for research purposes. Study Design: The main issues addressed were defining the major health and developmental domains to be investigated, selection of age-appropriate validated instruments, considering time constraints to maximize compliance, and budgetary limitations. The final protocol included a half-hour structured telephone interview with mothers of all 759 children and a 2-h developmental assessment of 294 of them. Each of the instruments and recruiting methods are described in terms of the abovementioned considerations. Results: Almost all of the mothers who agreed to be interviewed completed it within the half-hour allotted; however only about half of those who agreed to bring the child for the developmental assessment actually did so. The entire examination battery, assessing cognitive ability, executive functions, attention, and learning skills, was completed by almost all 294 children. There was a significant degree of agreement between the maternal report of the child's reading, writing and arithmetic skills and the in-person examination, as well as regarding the child's weight and height measurements. Conclusion: The findings lend support for a low-budget study, relying on telephone interviews. However, limitations such as the validity of maternal report and recall bias must be taken into consideration.

A case-control study of caesarean delivery on maternal request: who and why?

OBJECTIVE: The current study aimed to evaluate the profile of women who are most likely to undergo caesarean delivery on maternal request (CDMR) and clarify their reasons for this decision. METHODS: For this multicentre case-control study, data were collected from 429 women who underwent CDMR and 429 matched controls who delivered vaginally from June, 2008 through February, 2009. Participants were interviewed by telephone regarding sociodemographic variables, health and lifestyle. RESULTS: CDMR predictors were as follows: increasing age (OR = 1.09/year; 95%CI: 1.05-1.14), family status (unmarried without a steady partner versus married - OR = 3.60; 95%CI: 1.08-11.97), decreasing level of religiosity (secular versus ultra-orthodox - OR = 11.82; 95%CI: 3.75-37.21), and never having engaged, or ceasing sports activity during pregnancy (OR = 1.79; 95%CI: 1.09-2.91 and 2.38; 95%CI: 1.28-4.43, respectively). Above average income reduced the probability of CDMR (OR = 0.56; 95%CI: 0.33-0.94). The most frequent reasons for choosing CDMR were concern for pain (21.9%), concern for their own or baby's health (20.4% and 16.5%, respectively) and emotional aspects (10.0%). CONCLUSIONS: Older, unmarried and/or secular women had increased probability of CDMR. Addressing specific concerns regarding vaginal delivery may provide the basis for a patient-oriented intervention for preventing unnecessary surgery.

Association between BRCA1 and BRCA2 mutations and survival in women with invasive epithelial ovarian cancer.

CONTEXT: Approximately 10% of women with invasive epithelial ovarian cancer (EOC) carry deleterious germline mutations in BRCA1 or BRCA2. A recent article suggested that BRCA2-related EOC was associated with an improved prognosis, but the effect of BRCA1 remains unclear. OBJECTIVE: To characterize the survival of BRCA carriers with EOC compared with noncarriers and to determine whether BRCA1 and BRCA2 carriers show similar survival patterns. DESIGN, SETTING, AND PARTICIPANTS: A pooled analysis of 26 observational studies on the survival of women with ovarian cancer, which included data from 1213 EOC cases with pathogenic germline mutations in BRCA1 (n = 909) or BRCA2 (n = 304) and from 2666 noncarriers recruited and followed up at variable times between 1987 and 2010 (the median year of diagnosis was 1998). MAIN OUTCOME MEASURE: Five-year overall mortality. RESULTS: The 5-year overall survival was 36% (95% CI, 34%-38%) for noncarriers, 44% (95% CI, 40%-48%) for BRCA1 carriers, and 52% (95% CI, 46%-58%) for BRCA2 carriers. After adjusting for study and year of diagnosis, BRCA1 and BRCA2 mutation carriers showed a more favorable survival than noncarriers (for BRCA1: hazard ratio [HR], 0.78; 95% CI, 0.68-0.89; P < .001; and for BRCA2: HR, 0.61; 95% CI, 0.50-0.76; P < .001). These survival differences remained after additional adjustment for stage, grade, histology, and age at diagnosis (for BRCA1: HR, 0.73; 95% CI, 0.64-0.84; P < .001; and for BRCA2: HR, 0.49; 95% CI, 0.39-0.61; P < .001). The BRCA1 HR estimate was significantly different from the HR estimated in the adjusted model (P for heterogeneity = .003). CONCLUSION: Among patients with invasive EOC, having a germline mutation in BRCA1 or BRCA2 was associated with improved 5-year overall survival. BRCA2 carriers had the best prognosis.

The effect of active immunization on varicella-related hospitalizations in Israel.

The purpose of this study is to report on the impact of introduction of the varicella vaccine "Varilix" on hospitalizations due to varicella, following licensure in Israel in June, 2000. Data on children hospitalized throughout Israel with the diagnosis of varicella were collected from 1998 until 2003. The national rate of varicella-related hospitalizations decreased during the period 2001-2002. However in 2003 an increase in hospitalization occurred. Based on an assumption that at least 22,000 vaccinations per year were administered, we estimate that there is a greater than 60% reduction in the risk for hospitalization in the immunized population (RR = 0.32; 0.10-1.00). In summary, no national trend in reduction of hospitalization has yet been observed, but a significant reduction in hospitalization is apparent for vaccinated children.

Effect of BRCA1/2 mutations on long-term survival of patients with invasive ovarian cancer: the national Israeli study of ovarian cancer.

PURPOSE: To evaluate the long-term survival of ovarian cancer (OvC) patients in total and by BRCA1/2 mutation status. PATIENTS AND METHODS: In a nationwide case-control study on OvC conducted in Israel between 1994 and 1999, 779 Jewish women with epithelial invasive OvC were tested for the three Ashkenazi Jewish founder mutations in BRCA1 (185delAG; 5382insC) and BRCA2 (6174delT) genes and followed for survival up to 2003. Of the 605 women of Ashkenazi origin, 213 (35.2%) carried a mutation in the BRCA1/2 genes. Clinical characteristics were abstracted from the patients' medical records. The Kaplan-Meier method, log-rank tests, and stepwise Cox regression model were used for survival analyses. RESULTS: The 5-year survival rate for the entire group was 39%. Median survival for carriers was significantly longer than for noncarriers (53.7 v 37.9 months, respectively; P = .002). This differential survival was pronounced among women diagnosed at stages III to IV (5-year survival rates of 38.1% and 24.5% for carriers and noncarriers, respectively; P < .001) and for women with poor grade (45.4% v 31.5%, for carriers and noncarriers, respectively; P < .001). These results remained significant after controlling for age at diagnosis, grade, and morphology. This benefit in prognosis was seen for both BRCA1 and BRCA2 carriers compared with noncarriers. During the study period (median follow-up, 6.2 years), being a BRCA1/2 mutation carrier decreased the mortality rate by 28%. CONCLUSION: This study confirms that, among Ashkenazi OvC patients, BRCA1/2 mutations are associated with improved long-term survival. This may be due to distinct clinical behavior and/or to a better response to chemotherapy.

Nosocomial bloodstream infections in a pediatric intensive care unit: 3-year survey.

BACKGROUND: Bloodstream infections (BSI) represent a major cause of hospital-acquired infections in pediatric intensive care unit (PICU) patients. This study was designed to determine the prevalence, risk factors and outcomes of these infections in one local facility. MATERIAL/METHODS: All patients admitted to one PICU between January 1, 2000 - December 31, 2002 and subsequently developed a nosocomial bloodstream infection (NBSI) were consecutively recruited. The study was a retrospective study. Data retrieved from medical records included demographic information, extrinsic (invasive devices) and intrinsic risk factors, specific pathogens, therapeutic interventions and outcome. RESULTS: There were 95 episodes of NBSIs in 59 patients (63/1711 PICU admissions, yielding an incidence of 56/1000). The crude mortality rate (CMR) in children with NBSIs was 52%, compared with 6% for all other children admitted to the PICU. A higher CMR was associated with hemato-oncology illness, prolonged length of hospitalization (>1 month) mechanical ventilation, dialysis and severity of illness. Most of the patients (95%) had central intravascular devices, and 73% of the episodes were catheter-related infections. The most frequent pathogens were coagulase-negative staphylococci (24%), Klebsiella pneumonia (16%), Candida spp. (15%), Pseudomonas aeruginosa (7%) and Staphylococcus aureus (6%). Thirty-three percent of the Staphylococcus aureus were methicillin resistant (MRSA) and 30% of the Klebsiella pneumonia were extended - spectrum beta-lactamase - producing (ESBL) strains. CONCLUSIONS: The overall incidence of NBSIs was 56 episodes per 1000 admissions. The major risk factors were hemato-oncology illness, prolonged length of hospitalization, mechanical ventilation, dialysis and severity of illness. Children with NBSI had a poor outcome when compared with children without NBSI.

The impact of educational intervention programs on pain management in a pediatric emergency department.

Management of pain and anxiety is an important part of patient care in the pediatric emergency department (ED). Even though it has improved significantly over the past few years, it is still suboptimal. The objective of this study was to evaluate the effect of informal and formal education on pain and anxiety management in the pediatric ED. Management of pain and anxiety was assessed by comparing the use of analgesics and sedatives during three phases: A) year 2000 (baseline), B) years 2001-2002 (informal teaching) and C) year 2004 (following a structured simulation-based training in pediatric sedation and analgesia). During period B there was a significant increase in the yearly use of eutectic mixture of local anesthetics (EMLA) (RR=2.63, CI 1.23-5.6), ibuprofen (RR=14.16, CI 8.73-22.98), midazolam (RR=1.68, CI 1.39-2.03) and nitrous oxide (N2O) in comparison with period A, with an additional increment of the first three medicines during period C. There was no change in the use of ketamine, morphine and meperidine during period B. Whereas, during period C, a significant increase in the use of ketamine and morphine was demonstrated (RR=24.56, CI 10.71-56.3 and RR=3.07, CI 2.12-4.44, respectively), while the use of meperidine (RR=0.68, CI 0.49-0.94) and N2O (RR=0.46, 95% CI 0.32-0.67) declined significantly. Educational interventions have a clear impact on pain and anxiety management demonstrated by the subsequent change in the use of sedatives and analgesics and should be provided to pediatric ED physicians. Informal teaching affected mainly the use of milder sedatives and analgesics, while formal structured training influenced the use of opioids and dissociative agents.

Demographic and genetic characteristics of patients with borderline ovarian tumors as compared to early stage invasive ovarian cancer.

OBJECTIVE: Evaluation whether Jewish founder mutations in BRCA predispose to borderline tumors as they do to early invasive ovarian cancers. METHODS: All Jewish women with borderline or invasive ovarian tumors, diagnosed over a 5-year period (1994-1999), were identified in the frame of a nationwide epidemiological study on ovarian cancer in Israel. Out of a total of 1489 patients, 1269 were interviewed; of them 256 (20.2%) patients were identified with stage I and II invasive epithelial ovarian tumors, and 233 (18.3%) patients were identified with borderline tumors. All patients underwent interviews, and blood or tissue samples from 117 borderline tumors and 161 early stage invasive tumors were analyzed for the presence of the 185delAG and 5382insC BRCA1, and the 6174delT BRCA2 Jewish founder mutations. RESULTS: Patients with borderline tumors were younger at diagnosis, and more frequently of the serous type (P < 0.001) as compared to patients with early stage ovarian cancer. Prevalence of Jewish founder mutations in BRCA1 and BRCA2 was only 4.3% of patients with borderline tumors as compared to 24.2% of patients with early stage ovarian cancer (P = 0.001). CONCLUSIONS: This nationwide study comparing patients with early stage borderline and invasive epithelial tumors of the ovary confirms our previous pilot study that showed a lower incidence of BRCA mutations in patients with borderline tumors. Our results suggest that the genetic predisposition and the molecular mechanisms underlying tumor initiation differ between invasive and borderline tumors of the ovary.
