Focus on fathers: paternal depression in the perinatal period.

AIMS: This report aims to present a concise overview and synthesis of current research findings regarding paternal depression in the perinatal period. METHODS: A literature search was conducted, primarily via PubMed and PsychNET, for English-language research studies and meta-analyses using combinations of the terms 'perinatal', 'pregnancy', 'postpartum', 'depression' AND 'fathers' OR 'paternal'. Peer-reviewed articles were considered, and a representative sample of literature, with an emphasis on recent publications from a broad range of populations was summarized for each of the following sub-sections: prevalence, risk factors, impact on the infant/child, and healthcare costs. RESULTS: Reported prevalence has ranged from 2.3% to 8.4%, with a significant degree of heterogeneity in rates, due to differences in multiple aspects of the methodology (timing, instruments, etc.). Nevertheless, rates of maternal depression remain higher than paternal depression, and higher rates of one are associated with higher rates of the other. The primary risk factors for paternal depression are maternal depression and the father's history of severe depression, or symptoms of depression or anxiety prenatally. Biological mechanisms may underlie paternal depression, with changes reported in testosterone, cortisol and prolactin levels during this period. Paternal depression has been related to children's behavioral, emotional and social function at 36 months and psychiatric disorders at 7 years, adjusting for maternal depression. Healthcare costs may also be impacted by paternal postpartum depression, with higher father-child dyad costs found after controlling for potential confounders. CONCLUSIONS: Focusing on fathers' emotional well-being in the perinatal period is important in itself, as well as for their wives and children. Programs recommending screening for maternal perinatal mood and anxiety disorders should include inquiry regarding the father's emotional state, and if his distress is reported it should be clarified and followed-up by support and intervention as necessary.

Delivery room resuscitation and adverse outcomes among very low birth weight preterm infants.

OBJECTIVE: To evaluate risk factors and impact of delivery room cardiopulmonary resuscitation (DR-CPR) on very low birth weight (VLBW) preterm infants. STUDY DESIGN: A national, population-based, observational study evaluating risk factors and short-term neonatal outcomes associated with DR-CPR among VLBW, extremely preterm infants (EPIs, 24 to 27 weeks' gestation) and very preterm infants (VPI, 28 to 31 weeks' gestation) born in 1995 to 2010. RESULTS: Among 17 564 VLBW infants, 636 (3.6%) required DR-CPR. In the group of 6478 EPI, 412 (6.4%) received DR-CPR compared with 224 of 11 086 infants (2.0%) in the VPI group. EPI who underwent DR-CPR had higher odds ratios (ORs (95% confidence interval)) for mortality compared to EPI not requiring DR-CPR (OR 3.32 (2.58, 4.29)), grades 3 to 4 intraventricular hemorrhage (IVH) (OR 1.59 (1.20, 2.10)) and periventricular leukomalacia (OR 1.81 (1.17, 2.82)). DR-CPR among VPI was associated with higher ORs for mortality (OR 4.99 (3.59, 6.94)), early sepsis (OR 2.07 (1.05, 4.09)), grades 3 to 4 IVH (OR 3.74 (2.55, 5.50)) and grades 3 to 4 retinopathy of prematurity (ROP) (OR 2.53 (1.18, 5.41)) compared to VPI not requiring DR-CPR. Only 11% of infants in the EPI DR-CPR group had favorable outcomes compared with 44% in the VPI DR-CPR group. Significantly higher ORs for mortality, IVH and ROP were found in the VPI compared to the EPI group. CONCLUSION: Preterm VLBW infants requiring DR-CPR were at increased risk of adverse outcomes compared to those not requiring CPR. This effect was more pronounced in the VPI group.

Risk factors associated with post-hemorrhagic hydrocephalus among very low birth weight infants of 24-28 weeks gestation.

OBJECTIVE: Post-hemorrhagic hydrocephalus (PHH) is associated with morbidity and mortality among very low birth weight (VLBW) infants. This study aimed to determine risk factors for PHH among VLBW infants with peri-intraventricular hemorrhage (PIVH). STUDY DESIGN: This is a population-based cohort of VLBW infants of 24 to 28 weeks gestation, born in Israel from 1995 to 2012. Infants in whom a brain ultrasound was not performed before 28 days or with major congenital malformations were excluded. Univariate and multivariable analyses identified risk factors associated with PHH. RESULTS: The final study cohort comprised 2811 infants with grade 2 or higher PIVH, of whom 610 (21.7%) developed PHH. PHH was independently associated with PIVH severity, with bilateral grade 3 PIVH and PIVH grade 3 and contralateral grade 4 having the highest risks (odds ratio (OR) 12.2, 95% confidence interval (CI) 8.56 to 17.4 and OR 13.7, 95% CI 9.4 to 20.1, respectively). Unilateral grade 3 or 4 PIVH's had moderately increased risks of PHH (OR 3.50, 95% CI 2.26 to 5.42 and OR 3.79, 95% CI 2.35 to 6.12, respectively). PHH was independently associated with increasing gestational age (GA) and with neonatal morbidities including patent ductus arteriosus (OR 1.47, 95% CI 1.15 to 1.88 if medically treated and OR 3.01, 95% CI 2.11 to 4.29 if surgically treated), sepsis (OR 1.79, 95% CI 1.44 to 2.22) and necrotizing enterocolitis (OR 1.60, 95% CI 1.18 to 2.17). CONCLUSIONS: Among VLBW infants with PIVH, PHH was independently associated with PIVH severity group, increasing GA and acute neonatal morbidities. Unilateral grade 3 or 4 PIVH was associated with a moderate risk of developing PHH compared with bilateral severe hemorrhages.

Glycemic control and clinic attendance of emerging adults with type 1 diabetes at a transition care clinic.

BACKGROUND: Emerging adulthood is a challenging period for diabetes management. Our aim was to determine whether a dedicated transition clinic for emerging adults with type 1 diabetes can improve glycemic control and visit attendance. METHODS: An observational study of 53 emerging adults (30 males) treated during 2010-2014 in a newly established transition clinic. The clinic was operated jointly by pediatric and adult endocrinologists and included a transition coordinator. Data collected included the source of referral, HbA1c levels, frequency of visit attendance, and acute complications. For 27 patients who had attended the pediatric clinic at the same medical center, data from up to 2 years preceding the transition were also collected. Patients filled the Diabetes Quality of Life-Youth questionnaire at the transition and 1 year later. RESULTS: Mean ± SD age at the transfer to the transition clinic was 22.1 ± 2.7 years; mean disease duration was 8.4 ± 5.0 years. Follow-up duration at the transition clinic was 1.2 ± 1.1 years. Mean HbA1c levels decreased from 67 mmol/mol (95 % CI 63-72) [8.3 % (95 % CI 7.9-8.7)] at transfer to 57 mmol/mol (95 % CI 52-63) [7.4 % (95 % CI 6.9-7.9)] after 1 year (p < 0.001). Thirty-six patients (68 %) attended three or more visits during their first year in the transition clinic. The impact of diabetes on quality of life, disease-related worries, and life satisfaction did not change significantly during 1-year attendance in the transition clinic. CONCLUSIONS: A dedicated transition clinic for emerging adults, with tailored support according to the developmental needs of emerging adulthood, showed improved glycemic control and visit attendance.

Antenatal corticosteroid treatment in singleton, small-for-gestational-age infants born at 24-31 weeks' gestation: a population-based study.

OBJECTIVE: To assess the impact of antenatal corticosteroid therapy on mortality and severe morbidities in preterm, small-for-gestational-age (SGA) neonates compared with preterm non-SGA neonates. DESIGN: Population-based study. SETTING/POPULATION: Israel National Very Low Birth Weight infant database from 1995-2012. METHODS: Singleton infants of 24-31 weeks' gestation, without major malformations. Antenatal corticosteroids were considered either any treatment or no treatment. MAIN OUTCOME MEASURES: Univariate and multivariable logistic regression analyses were performed to assess the effect of antenatal corticosteroids on neonatal mortality and a composite adverse outcome of mortality or severe neonatal morbidity. RESULTS: Among the 10 887 study infants, 1771 were SGA. Of these, 70.4% of SGA and 66.7% of non-SGA neonates were exposed to antenatal corticosteroids. Among SGA neonates, antenatal corticosteroids were associated with decreased mortality (32.2 versus 19.3%, P < 0.0001) and composite adverse outcome (54.1 versus 43.4%, P < 0.0001), similar to the effect in non-SGA neonates (mortality 26.7 versus 12.2%, P < 0.0001; composite outcome 50.5 versus 34.6%, P < 0.0001). Multivariable logistic regression analyses demonstrated a 50% reduction in mortality risk among SGA and 57% reduction in non-SGA neonates exposed to corticosteroids [OR = 0.50, 95% confidence interval (95% CI) 0.39-0.64 and OR = 0.43, 95% CI 0.38-0.47, respectively], P-value for interaction = 0.08. Composite adverse outcome risk was significantly reduced in SGA (OR = 0.67, 95% CI 0.54-0.83) and non-SGA infants (OR = 0.57, 95% CI 0.52-0.63), P-value for interaction = 0.04. CONCLUSIONS: Antenatal corticosteroids significantly reduced mortality and severe morbidities among preterm SGA neonates, with slightly a less pronounced effect compared with non-SGA preterm infants. Antenatal corticosteroids should be given to fetuses suspected of intrauterine growth retardation, at risk for preterm delivery, in order to improve perinatal outcome. TWEETABLE ABSTRACT: Antenatal steroids reduced mortality and severe morbidities among singleton, preterm SGA neonates.

Perinatal factors associated with active intensive treatment at the border of viability: a population-based study.

OBJECTIVE: The aim of this national population-based study was to identify perinatal and neonatal factors associated with active intensive treatment (AIT) of infants born at the periviable period of 22 to 24 weeks of gestation. STUDY DESIGN: Data from the Israel national very low-birth weight infant database on 2207 infants born alive in 1995 to 2010 at gestational age (GA) 22 to 24 weeks were evaluated. AIT was defined as endotracheal intubation in the delivery room or mechanical ventilation in the neonatal intensive care unit. Multivariable logistic regression analyses were used to identify the independent effect of demographic and perinatal factors on AIT for each gestational week. RESULT: Of the 2207 infants born at 22 to 24 weeks GA, 1643 (74.4%) received AIT and 564 (25.6%) received comfort care. AIT increased from 25.5% at 22 weeks to 62.7 and 93.5% at 23 and 24 weeks GA, respectively, reflecting a 4.66 (95% confidence interval (CI) 3.32 to 6.54)- and 29.8 (95% CI 19.9 to 44.6)-fold odds for AIT at 23 and 24 weeks GA, respectively, compared with 22-week GA infants. Perinatal treatments associated with AIT included maternal tocolytic therapy (odds ratio (OR) 1.51, 95% CI 1.04 to 2.20), prenatal steroid therapy, both partial (OR 3.30, 95% CI 2.14 to 5.10) and complete (OR 3.17, 95% CI 1.91 to 5.26) and cesarean delivery (OR 2.68, 95% CI 1.88 to 3.83). Each unit increase in birth weight z-score was associated with an OR of 1.58 (95% CI 1.30 to 1.92) for AIT. At 22 weeks GA, maternal tocolytic treatment was associated with higher odds of AIT. In the 23 and 24-week GA infants, maternal infertility treatment, antenatal steroids, cesarean delivery and higher-birth weight z-scores were significantly associated with AIT. Among 23-week GA infants, AIT decreased significantly in the period 2006 to 2010 compared with 1995 to 2000 (OR 0.51, 95% CI 0.34 to 0.77). CONCLUSION: An active approach in obstetric management of pregnancies appears to impact the neonatologists' decision to undertake AIT treatment in infants born at the border of viability. The higher odds for AIT associated with obstetric interventions might contribute to the reported beneficial effect of antenatal steroids and cesarean delivery on the survival of infants born at the border of viability.

Health outcomes of children born after IVF/ICSI: a review of current expert opinion and literature.

The Sixth Evian Annual Reproduction (EVAR) Workshop Group Meeting was held to evaluate the impact of IVF/intracytoplasmic sperm injection on the health of assisted-conception children. Epidemiologists, reproductive endocrinologists, embryologists and geneticists presented data from published literature and ongoing research on the incidence of genetic and epigenetic abnormalities and congenital malformations in assisted-conception versus naturally conceived children to reach a consensus on the reasons for potential differences in outcomes between these two groups. IVF-conceived children have lower birthweights and higher peripheral fat, blood pressure and fasting glucose concentrations than controls. Growth, development and cognitive function in assisted-conception children are similar to controls. The absolute risk of imprinting disorders after assisted reproduction is less than 1%. A direct link between assisted reproduction and health-related outcomes in assisted-conception children could not be established. Women undergoing assisted reproduction are often older, increasing the chances of obtaining abnormal gametes that may cause deviations in outcomes between assisted-conception and naturally conceived children. However, after taking into account these factors, it is not clear to what extent poorer outcomes are due to the assisted reproduction procedures themselves. Large-scale, multicentre, prospective epidemiological studies are needed to investigate this further and to confirm long-term health consequences in assisted-conception children. Assisted reproduction treatment is a general term used to describe methods of achieving pregnancy by artificial means and includes IVF and sperm implantation. The effect of assisted reproduction treatment on the health of children born using these artificial methods is not fully understood. In April 2011, fertility research experts met to give presentations based on research in this area and to look carefully at the evidence for the effects of assisted reproduction treatment on children's health. The purpose of this review was to reach an agreement on whether there are differences in the health of assisted-conception children with naturally conceived children. The researchers discovered no increased risk in birth defects in assisted-conception children compared with naturally conceived children. They found that IVF-conceived children have lower birth weights and higher fat under the skin, higher blood pressure and higher fasting glucose concentrations than naturally conceived children; however, growth, development and cognitive function are similar between groups. A very low risk of disorders of genetic control was observed in assisted-conception children. Overall, there did not appear to be a direct link between assisted reproduction treatment and children's health. The researchers concluded that the cause of some differences in the health of children conceived using assisted reproduction treatment may be due to the age of the woman receiving treatment. Large-scale, research studies are needed to study the long-term health of children conceived using assisted reproduction treatment.

Congenital malformations in infants conceived following assisted reproductive technology in comparison with spontaneously conceived infants.

OBJECTIVE: To evaluate the risk for congenital malformations diagnosed at birth following assisted reproductive technology (ART) treatments compared with live births conceived spontaneously. METHODS: A retrospective cohort study including 9042 live births following ART and 213 288 spontaneously conceived (SC) live births during the period 1997-2004.The cohort was linked to the national live birth registry to determine the outcome of the pregnancies including congenital malformations. RESULTS: An increased adjusted risk for all congenital malformations was observed in ART compared with SC infants [2.4% versus 1.9%; ORadj = 1.45; 95% CI: 1.26, 1.68]. The increased risk was observed in singleton births [2.4% versus 1.8%; ORadj = 1.41; 95% CI: 1.14, 1.71] but not in the ART conceived multiple births [2.5% versus 2.6%.; ORadj = 1.15; 95% CI: 0.90, 1.46]. Significantly increased adjusted risks for nervous, circulatory, digestive and genital system malformations were evident in the ART singleton group compared to SC infants. In addition, increased risks were also observed in separate comparisons of IVF births versus SC [ORadj = 1.28; 95% CI: 1.00, 1.63] and ICSI births versus SC [ORadj = 1.56; 95% CI: 1.31, 1.84]. Data regarding pregnancy termination or congenital malformation diagnosed later in life were not included. CONCLUSION: Infants born following ART were at significantly increased risk for congenital malformations compared to live birth conceived spontaneously.

Maternal and neonatal health outcomes following assisted reproduction.

This study assessed the risk for maternal complications in women and neonatal outcomes in children conceived following assisted reproductive treatment as compared with spontaneously conception and also separately evaluated conventional IVF and intracytoplasmic sperm injection (ICSI). The prospective cohort included 1161 women with singleton pregnancies: 561 who conceived following assisted reproduction (223 following IVF and 338 following ICSI) and 600 who conceived spontaneously. No differences were observed in pregnancy complications (including spontaneous abortion, pregnancy-induced hypertension, gestational diabetes and Caesarean delivery) except for significantly increased risk for excess vaginal bleeding in assisted reproduction pregnancies (21.4% versus 12.9%; OR 1.67, 95% CI 1.18-2.37), which was prominent in women who reported polycystic ovary syndrome. Neonates born following assisted reproduction had increased risk for prematurity (10.6% versus 5.3%; OR 1.72, 95% CI 1.04-2.87), and IVF, but not ICSI, was associated with significantly increased risk for prematurity (OR 2.36, 95% CI 1.28-4.37) and low birthweight (OR 1.89, 95% CI 1.03-3.46). In conclusion, this study observed only an increased risk for excess vaginal bleeding as a pregnancy-associated complication in singleton pregnancies following assisted compared with spontaneous conception. However, singleton neonates born following IVF, but not ICSI, were at increased risk for prematurity.

Benefits of continuous subcutaneous insulin infusion (CSII) therapy in preschool children.

OBJECTIVE: The incidence of type 1 diabetes mellitus (T1DM) in young children has increased considerably over recent years. The purpose was to examine the effectiveness and safety of continuous subcutaneous insulin infusion (CSII) therapy in preschool children with T1DM. METHODS: A retrospective chart review of 113 children diagnosed with T1DM while younger than age 6 years. Mean age at diagnosis was 3.5±1.5 years and mean duration of follow 9.7±7.0 years. Patients were divided into 3 groups. Group1 initiated CSII therapy before the age of 6 years (n=26), Group 2 was treated with multiple daily injections (MDI) throughout follow-up (n=34), and Group 3 initiated CSII after age 6 (n=53). Metabolic control was assessed by HbA1C levels and safety by rates of severe hypoglycemia and diabetic ketoacidosis (DKA) events. RESULTS: In Group 1, the highest mean HbA1C value (8.5%) was observed 1-2 years prior to CSII initiation. During the 5 year period following CSII initiation, mean HbA1C levels ranged between 7.4 and 8.0%. Throughout the entire follow-up period, mean HbA1C levels were lower for Group 1 than Group 2 (p=0.05). In Group 3, mean HbA1C level decreased from 8.7% pre-CSII to 8.3% post-CSII (p<0.001). Nevertheless HbA1C levels remained higher than for those who started pump therapy before age 6 (p=0.02). CONCLUSIONS: Our study demonstrated better metabolic control in pre-school children treated with CSII compared to those treated with MDI. This benefit sustained for 5 years after CSII initiation and was not accompanied by increased risk of severe hypoglycemia or DKA events.

Type 1 diabetes in pre-school children--long-term metabolic control, associated autoimmunity and complications.

AIMS: To identify clinical characteristics and co-morbidity rates of children diagnosed with Type 1 diabetes mellitus at younger than 6 years of age. METHODS: Data were obtained from a retrospective chart review of 103 patients diagnosed with Type 1 diabetes at younger than 6 years (study group) and 220 patients at older than 6 years (comparison group). Measures of glycaemic control and occurrence of co-morbidities (coeliac disease, autoimmune thyroid disease, hypertension, nephropathy and retinopathy) were compared. RESULTS: The mean follow-up period was more than 8 years. For the study group, mean HbA(1c) levels ranged from 64 mmol/mol to 66 mmol/mol (8.0-8.2%) until age 10 years, and then rose to 73 mmol/mol (8.8%). The HbA(1c) levels were higher in the study than in the comparison group for comparable ages (P = 0.003). After adjustment for duration of diabetes this difference was not significant. The overall rate of severe hypoglycaemic events was greater in the study group than in the comparison group (P = 0.03). Kaplan-Meier diagnosis rates of celiac disease, 10 years after Type 1 diabetes diagnosis, were 14.4% and 4.2% in the study and comparison groups, respectively (P log-rank = 0.03). There were no differences in rates of autoimmune thyroid disease, hypertension, nephropathy or retinopathy. CONCLUSIONS: Children diagnosed with Type 1 diabetes before the age of 6 years were in greater risk of developing celiac disease, compared with children diagnosed after the age of 6 years. For children diagnosed with Type 1 diabetes aged under 6 years, good metabolic control was achievable until age 10 years, after which it deteriorated. Higher HbA(1c) levels observed in children diagnosed before the age of 6 years were associated with longer duration of disease.

Ovarian stimulation: is there a long-term risk for ovarian, breast and endometrial cancer?

Adverse effects have been related to infertility treatments. Infertility in general, and female infertility in particular, is a well established risk factor for cancer development, especially ovarian, breast and endometrial cancer. This article addresses the possible association between infertility and cancer development, with an emphasis on the influence of infertility treatments, through a meticulous search of the literature published thus far. While results regarding the possible association of infertility, ovulation induction medications and invasive ovarian cancer show no increased risk and are reassuring, results for increased risk for breast cancer and endometrial cancer following exposure to ovarian stimulation medications are inconclusive. Larger population studies with longer periods of follow-up and better adjustment for confounding factors are needed.

Prevalence of overweight in kindergarten children in the centre of Israel - association with lifestyle habits.

OBJECTIVES: (1) To determine the prevalence of overweight and at risk for overweight in a sample of 4- to 6-year-old Israeli children; and (2) to delineate factors which may be associated with excess of overweight such as food intake, food habits physical and sedentary activity, family and socio-economic factors. METHODS: In a cross-sectional survey in six kindergartens in the centre of Israel, 204 children (104 boys), mean age 5.5 years were studied. RESULTS: In total, 40% of the children were either at risk for overweight (25%) or overweight (15%). Parents of one-third of all children reported their children ate unbalanced meals; however, caloric intake was not different between the weight groups. Overweight children were reported to eat according to mood status and preferred eating candies. Knowledge of dietary requirements was fairly good and similar in all three weight groups. Screen viewing time was more than twofold greater than the recommended in all weight groups. The rate of parental obesity was not different in the weight groups. CONCLUSIONS: A high rate of overweight was documented among pre-schoolers in the centre of Israel. Poor lifestyle habits were noted in about one-third of all children; however, no association was found between the poor lifestyle habits and overweight but more overweight children eat according to mood status and preferred eating candies as a snack.

The possible association between IVF and breast cancer incidence.

BACKGROUND: The possible association between ovulation-inducing drugs and breast cancer development has been debated. Our aim was to evaluate the incidence of breast cancer in a cohort of women exposed to in vitro fertilization (IVF). METHODS: A retrospective cohort analysis was performed by linkage of the computerized database of all women treated at the IVF Unit at Assaf Harofeh Medical Center between 1986 and 2003, and the Israeli National Cancer Registry. The standardized incidence ratio (SIR) was computed as the ratio between the observed number of breast cancer cases and the expected cases, adjusted for age and continent of birth, in the general population. Tumor characteristics of the IVF patients were studied by reviewing original medical records. RESULTS: 35 breast carcinomas were diagnosed among 3,375 IVF-treated women, compared to 24.8 cases expected (SIR = 1.4; 95% CI 0.98-1.96). Age >or=40 years at IVF treatment (SIR = 1.9; 95% CI 0.97-3.30), hormonal infertility (SIR = 3.1; 95% CI 0.99-7.22), and >or=4 IVF cycles (SIR = 2.0; 95% CI 1.15-3.27) were found to be risk factors to develop breast cancer compared to the general population. Multivariate analysis revealed that women who underwent >or=4 IVF cycles compared to those with one to three cycles were at risk to develop breast cancer, although not significantly (SIR = 1.9; 95% CI 0.95-3.81). Of IVF-treated women 85% had ER(+) tumors and 29% had positive family history. CONCLUSIONS: A possible association between IVF therapy and breast cancer development was demonstrated, especially in women >or=40 years of age. These preliminary findings need to be replicated in other cohort studies.

Less postnatal steroids, more bronchopulmonary dysplasia: a population-based study in very low birthweight infants.

OBJECTIVE: To study the association between reduced use of postnatal steroids for bronchopulmonary dysplasia (BPD) in very low birthweight (VLBW) infants and oxygen (O(2))-dependency at 28 days of age and at 36 weeks postmenstrual age. DESIGN: Large national database study. SETTING: The Israel National VLBW Neonatal Database. PATIENTS: The sample included infants born between 1997 and 2004, of gestational age 24-32 weeks, who required mechanical ventilation or O(2) therapy. Four time periods were compared: 1997-8 (era 1, peak use), 1999-2000 (era 2, intermediate), 2001-2 (era 3, expected reduction) and 2003-4 (era 4, lowest). The outcome variable "oxygen dependency" was based on clinical criteria. Multivariate regression models were used to account for confounding variables. RESULTS: Steroid use fell significantly from 23.5% in 1997-8 to 11% in 2003-4 (p<0.005). After adjustment for relevant confounding variables, the odds ratio for O(2) therapy at 28 days in era 4 versus era 1 was 1.75, 95% confidence interval (CI) 1.47 to 2.09 and 1.41, 95% CI 1.15 to 1.73 at 36 weeks postmenstrual age. The mean duration of O(2) therapy increased from 25.3 days (95% CI 23.3 to 26.3) in era 1, to 28.0 days (95% CI 26.6 to 29.4) in era 4. Survival increased from 78.5% in era 1 to 81.6% in era 4 (p<0.005). CONCLUSIONS: The use of steroids has fallen considerably since the awareness of the adverse effects of this treatment. This change has been temporally associated with increased O(2) dependency at 28 days of age and at 36 weeks postmenstrual age. The prolongation of O(2) therapy was modest in degree.

Infertility, ovulation induction treatments and the incidence of breast cancer--a historical prospective cohort of Israeli women.

CONTEXT: Ovulation induction drugs may be associated with increased breast cancer risk. Results so far have been inconclusive. OBJECTIVE: To evaluate the association between infertility, exposure to ovulation induction drugs and the incidence of breast cancer. DESIGN: Historical prospective cohort and nested case-control study. SETTING: Institutional practice PATIENTS: About 5,788 women attending five infertility centers in Israel between 1964 and 1984. INTENTION: Abstracting of medical records and telephone interviews. MAIN OUTCOME MEASURE: Breast cancer incidence was determined through linkage with the National Cancer Registry database. Standardized incidence ratios (SIRs) and 95% confidence intervals were computed by comparing the observed to the expected cancer rates in the general population. In addition, a nested case-control study within the cohort was performed with interviews of breast cancer cases and two matched controls. RESULTS: The study cohort included 120,895 women years of follow-up. Compared to 115.2 expected breast cancer cases, 131 cases were observed (SIR = 1.1; 95% CI 0.9-1.4). Risk for breast cancer was significantly higher for women treated with clomiphene citrate (SIR = 1.4; 95% CI 1.0-1.8). Similar results were noted when comparisons were carried out between treated and untreated women, and when multivariate models were applied. In the nested case-control study, higher cycle index (OR = 2.2; 95% CI 1.0-4.8) and treatment with clomiphene citrate (OR=2.7; 95% CI 1.3-5.7) were associated with higher risk for breast cancer. CONCLUSION: Infertility and usage of infertility drugs in general are not associated with increased risk for breast cancer. However, for infertile women treated with clomiphene citrate, breast cancer risk is elevated.

A possible genetic factor in the pathogenesis of ovarian dermoid cysts.

This study was undertaken in order to evaluate a possible genetic influence on the pathogenesis of ovarian dermoid cysts. We have performed a case-control study comparing the prevalence of a history of dermoid cysts in first-degree relatives of women with dermoid cysts and among first-degree relatives of women without dermoid cysts. The study group included 285 women with an established diagnosis of ovarian dermoid cysts. The control group included 378 women with sonographically normal ovaries. To assess the relationship between a first-degree family history of dermoid cysts and the diagnosis of ovarian dermoid cysts, a multivariate stepwise logistic regression model was applied. In 28 families of the study group (9.8%), a dermoid cyst was found in at least 1 first-degree relative as compared with only eight families (2%) among the controls (adjusted odds ratio -5.60; 95% CI 2.24-14.2). The data suggest a genetic predisposition towards dermoid cysts which merits further exploration.

Reflexology treatment relieves symptoms of multiple sclerosis: a randomized controlled study.

OBJECTIVE: To evaluate the effect of reflexology on symptoms of multiple sclerosis (MS) in a randomized, sham-controlled clinical trial. METHODS: Seventy-one MS patients were randomized to either study or control group, to receive an 11-week treatment. Reflexology treatment included manual pressure on specific points in the feet and massage of the calf area. The control group received nonspecific massage of the calf area. The intensity of paresthesias, urinary symptoms, muscle strength and spasticity was assessed in a masked fashion at the beginning of the study, after 1.5 months of treatment, end of study and at three months of follow-up. RESULTS: Fifty-three patients completed this study. Significant improvement in the differences in mean scores of paresthesias (P = 0.01), urinary symptoms (P = 0.03) and spasticity (P = 0.03) was detected in the reflexology group. Improvement with borderline significance was observed in the differences in mean scores of muscle strength between the reflexology group and the controls (P = 0.06). The improvement in the intensity of paresthesias remained significant at three months of follow-up (P = 0.04). CONCLUSIONS: Specific reflexology treatment was of benefit in alleviating motor; sensory and urinary symptoms in MS patients.

The possible association between in vitro fertilization treatments and cancer development.

The objective of this paper is to assess whether ovarian hyperstimulation and in vitro fertilization (IVF) are associated with increased risk of cancer development, using an historical cohort analysis of infertile women who attended the IVF unit, Lis Maternity Hospital Tel Aviv Medical Center, Tel Aviv, Israel. One thousand and 82 women participated in the IVF treatment program between 1984 and 1992. Cancer incidence rates were determined through the National Cancer Registry and were compared to the expected rates with respect to appropriate age and continent of birth. Twenty-one cases of cancer were observed as compared to 11 that were expected (SIR 1.91; 95% CI 1.18-2.91). When cancer cases that were diagnosed within one year of the IVF treatment were excluded from the analysis (SIR = 1.46; 95% CI 0.83-2.36), no significant excess risk of cancer was noted. We conclude that in this cohort of infertile women, the higher than expected cancer rate could not be attributed to IVF treatments. Special attention should be made to women who may be diagnosed with cancer during or shortly after IVF treatment.

Pseudomonas aeruginosa bacteremia in children: analysis of trends in prevalence, antibiotic resistance and prognostic factors.

OBJECTIVE: To determine the factors predisposing to Pseudomonas aeruginosa bacteremia as well as the prevalence, source of infection, outcome and prognostic factors in pediatric patients. METHODS: Retrospective review of pediatric patients with P. aeruginosa bacteremia, at a large tertiary care hospital during a 6.5-year period. RESULTS: Seventy patients with P. aeruginosa bacteremia were identified. The annual rate of P. aeruginosa bacteremia remained unchanged during the study period. Antibiotic susceptibility remained unchanged except for two patients with extensive burns who developed resistant strains. Underlying diseases were malignancy (50%), prematurity (6%), burns (7%) and others (37%). The overall mortality associated with P. aeruginosa bacteremia was 20%. The fatality rate was higher among the young infants (compared with older children) and those who received previous antibiotic therapy (P = 0.02). Mortality rate was higher in nosocomial than in community-acquired infections (25% compared with 11.5%). The mortality rate of low birth weight and burns patients was significantly higher when compared with oncology patients or other patients, 75 and 40% compared with 11 and 19%, P = 0.01. Multiple regression analysis revealed a correlation only between the underlying disease and mortality (P = 0.02). In the oncology patients the only significant risk factor for mortality was absolute neutrophil count < or =0.1 x 10(9)/l (P = 0.06). CONCLUSION: P. aeruginosa bacteremia, although apparently not increasing in incidence and antibiotic resistance, is still a common serious complication in immunocompromised children with a high mortality rate. We conclude that the underlying disease is the main determinant of the clinical outcome.
