Researchers are looking at a wide variety of environmental exposures and risk factors as possible causes. Because most of the structural development of the fetus occurs during early pregnancy, studies usually focus on the periconceptional period, the month before and three months after conception. For the developing pregnancy, the environment includes any exposures to the fetus as well as any exposures to the mother. The Massachusetts combined lifetime costs for babies born with any of 12 major structural birth defects are an estimated $122 million in 2003 dollars (Harris, 1997; see Technical Notes for inflation adjustment). These figures include direct costs of medical treatment, developmental services and special education, as well as indirect costs to society for lost wages due to early death or occupational limitations. Over the past ten years, the Massachusetts Center for Birth Defects Research and Prevention has developed and refined its surveillance program. The first full year of population-based, active statewide surveillance data was 1999. The primary focus of the state surveillance system is the identification of major structural birth defects, with or without a chromosomal abnormality, and non-chromosomal malformation syndromes. Inborn errors of metabolism are monitored separately by the state newborn screening program. This report presents statewide data on the prevalence of birth defects in live births and stillbirths in Massachusetts primarily during the years 2002 and 2003. The first annual report presented Massachusetts birth defects data for the year 1999. Our ability to find and identify infants born with birth defects to Massachusetts residents has improved over time and is reflected in increased prevalence rates. The 2002-2003 data are presented in combined form since the numbers are relatively small for individual defects. Among the 160,791 live births to Massachusetts residents in 2002-2003, 2,476 had one or more birth defects. Three of the ten most common defects were cardiovascular defects: Atrial Septal Defects, Ventricular Septal Defects and Pulmonary Stenosis (Valvular). Common non cardiovascular defects included Trisomy 21, Polydactyly/Syndactyly, Hypospadias, Clubfoot, Cleft Lip with and without Cleft Palate, Cleft Palate alone, and Obstructive Genitourinary Defects. Massachusetts was one of 11 states with population-based monitoring programs to contribute birth defect data. The lower rates for the other defects may reflect differences in defect criteria between surveillance systems and regional differences. Spontaneous deliveries of stillbirths >= 20 weeks of gestation were reported by birthing hospitals but limited information about the stillbirth is included in the maternal record. Thus some birth defects are not well documented and are unable to be confirmed for inclusion in state surveillance. Birth defects which appeared more often in conjunction with other defects included the majority of Cardiovascular Defects, Limb Reductions, Hydrocephalus, Esophageal Atresia/Tracheoesophagela Fistula, Intestinal Atresias, and Obstructive Genitourinary Defects. Selected Pregnancy Outcomes We compared selected pregnancy outcomes (C-sections, birthweight, gestational age, multiple birth and infant death) among infants born with birth defects to those born without birth defects in 2002-2003. While numbers of 2 infants with birth defects are relatively small, it is important to recognize the impact of these outcomes when diagnosing and treating a baby with a birth defect. Plurality Examining the birth defect rate by plurality is important since birth defects are more common among multiple births and the number of multiple births has been increasing over time in Massachusetts. Birth defects that more commonly occurred in multiple births included Esophageal Atresia/Tracheoesophageal Fistula, Hypospadias, Coarctation of Aorta, Diaphragmatic Hernia and Polydactyly/Syndactyly. Maternal Age Monitoring birth defects by maternal age is important since the number of births to older mothers has been increasing over time in Massachusetts. As expected, there was a strong association of Down Syndrome with advanced maternal age. Although more babies with Down Syndrome were born to women under 35, the Down Syndrome rate of 29. Maternal Race / Hispanic Ethnicity the prevalence of birth defects varied by maternal race and Hispanic ethnicity. The most common defects in Whites included Septal Defects, Hypospadias, Down 3 Syndrome, Polydactyly/Syndactyly and Clubfoot. Severity A severity scale was developed by the Center in collaboration with our partners at Boston University and the Massachusetts General Hospital. If a case had multiple defects with equal severity, it was reviewed in detail by the Center Clinical Geneticist to determine severity category. These cases needed intensive medical care and planning for continuing care and long-term disability. Coordination between the Birth Defect Monitoring Program and maternal and child health programs helps to ensure services for identified children and to provide population-based information to inform program planning and prevention strategies. Two resource lists: "Selected National Resources" and "Public Health Resources in Massachusetts" accompany this report. One in every 28 families of a newborn is forced to deal with the reality that their baby has a birth defect (March of Dimes). Birth defects, sometimes called congenital anomalies, are abnormalities of structure, function or metabolism present before birth. Birth defects can lead to lifelong disability, require costly medical care and cause great distress in families. Although birth defects are rare when compared to other adverse birth outcomes, such as low birth weight or prematurity, they are the leading cause of death in the first year of life in the United States. Certain genetic and environmental factors have been implicated in selected defects. The gene may have an error in its code, a missing piece or extra genetic material, all of which can result in malformations. Other birth defects may be caused by a combination of factors, such as genes interacting with environmental factors. Researchers are looking at a wide variety of environmental exposures and risk factors as causes. For the developing pregnancy, the environment includes any exposure to the fetus as well as any exposure to the mother. Studies have shown that the presence of adequate amounts of folic acid (vitamin B9) in the mothers system during the periconceptional period may help prevent defects of the brain 8 and spinal cord known as neural tube defects. Mandatory fortification of cereal grains with folic acid has resulted in a 26% reduction in the number of babies born with these neural tube defects (Mills, 2004). Healthy People 2010 Challenges Healthy People 2010 established the objectives of reducing the fetal and infant death rates by 40%, developmental disabilities rates by 50%, and neural tube defect rates by 50%. Birth defects surveillance is a critical component of the public health strategy to achieve these objectives. The active surveillance program in Massachusetts allows the Department of Public Health to monitor the extent and occurrence of birth defects within the Commonwealth. Birth Defects Surveillance in Massachusetts Over the past ten years, the Center for Birth Defects Research and Prevention has developed and refined its surveillance program. The primary focus of the state surveillance system is the identification of major structural birth defects, with or without a chromosomal abnormality and non chromosomal malformation syndromes. Since over 70% of out-of-state births to Massachusetts mothers occur in Rhode Island, two Rhode Island hospitals, the Women and Infants Hospital and the Rhode Island Hospital, were added in 2000. In 2001, the Massachusetts Eye and Ear Infirmary was included in order to increase ascertainment of eye and ear anomalies that come to their attention. Birth certificates are checked for additional information such as residency of the mother. Abstractors have specialized training and ongoing education to abstract medical records of potential cases. Surveillance data are entered and maintained in a confidential electronic database. Economic Impact on Massachusetts Estimating the economic impact of birth defects on the state of Massachusetts is challenging. The California Birth Defects Monitoring Program and the Metropolitan Atlanta Congenital Defects Program, using 1992 data, calculated the lifetime costs for families dealing with a baby with birth defects to be between $75,000 and $503,000 (Waitzman et al. Their estimated lifetime costs for a baby born with Spina Bifida would be $364,560 in 2003 dollars. Adjusting for inflation, the Massachusetts combined lifetime costs for babies born with 12 major structural birth defects were an estimated $122 million in 2003 dollars (see Technical Notes). These figures included direct costs of medical treatment, developmental services and special education, as well as indirect costs to society for lost wages due to early death or occupational limitations. Legislative Changes Regarding Birth Defects Surveillance In March 2002, the Massachusetts Legislature amended the state birth defects monitoring statute (Chapter 111, section 67E) to allow expansion of the surveillance system to capture diagnoses through age three. It also extends mandated reporters to include attending physicians, primary care and specialist physicians who may diagnose birth defects. These physicians will now have a statutory duty to report within 30 days of making such a diagnosis. The 2002-2003 Surveillance Report this report presents statewide data on the prevalence of birth defects in live births and stillbirths in Massachusetts during the years 2002 and 2003. The data are presented in combined form since the numbers are relatively small for individual defects. The first annual report presented Massachusetts data for birth defects for the year 1999. Our ability to find and identify infants born with birth defects to Massachusetts residents has improved over time. There was about a 12% increase in cases from 2000-2001 to 10 2002-2003 that is attributable to this improved case ascertainment. Interpretations of these data must be made with caution until a multi-year estimate establishes a stable, baseline rate. Unless otherwise indicated the report uses the term births to mean live births plus stillbirths. A stillbirth was defined as the delivery of a fetus that was not alive, and was greater than or equal to 20 weeks gestational age, or weighed at least 350 grams. Cases met the following criteria: the infant was live born or, the fetus was stillborn with a gestational age greater than or equal to 20 weeks or with a weight of at least 350 grams. Hospitals across the state submitted monthly discharge lists with birth defect diagnoses to the Center. If the infant or fetus had a birth defect that met the case definition criteria, detailed demographic and diagnostic information was recorded on a hospital reporting form. This information was entered into a confidential surveillance database for analysis. The Center has developed extensive procedures to guarantee the confidentiality of data and protect the privacy of families. These procedures uphold our ethical and legal obligations to safeguard confidentiality and fully comply with the strict requirements of state and federal laws. If the case had more than one defect within the same defect category, only one of these defects was counted in the category total. If the case had more than one defect in different defect categories, the case was listed in the total for each of these defect categories. Thus the counts in the defect categories presented in the prevalence tables represent the total number of defects, not the total number of cases with birth defects. In this report, maternal age and race/ethnicity are drawn from the birth certificate. Because birth certificate data are more accurate for these fields than fetal death records, analyses of maternal age and race/ethnicity are limited to live births. Prevalence is calculated as the number of birth defect cases born during the period 2002-2003 per 10,000 live births born during the same period. Prevalence tables include the number of cases found, the estimated prevalence rate per 10,000 live births, and the 95% confidence interval for that rate. The incidence (new cases) of birth defects (based upon the number of embryos conceived within a year) is not fully measured because both the total number of conceptions that occur and the number of these conceptions resulting in a defect are not known (Sever 1996). Wide confidence intervals reflect the large variation due to small numbers (see Technical Notes). Birth defect counts for this report are only for calendar years 2002 through 2003. Due to the small numbers of birth defects, conclusions from these results are not valid until a more extensive multi-year estimate establishes a stable, baseline rate. Currently, the Massachusetts Birth Defects Monitoring Program ascertains cases only at birthing hospitals, two non-birthing tertiary care centers and one specialty care hospital. Thus, defects that are not diagnosed at birth and that do not need hospitalization may be underreported. Misclassification of birth defects may occur through coding errors or vague diagnoses. Quality control measures such as careful abstraction of the medical records minimize this error.

Confirm the onset of labour only if intermittent uterine contractions are associated with progressive changes in the cervix: Cervical effacement: the progressive shortening and thinning of the cervix in labour; the length of the cervix at the end of normal pregnancy is variable (a few millimetres to 3 cm); with the onset of labour erectile dysfunction treatment on nhs purchase 90 mg dapoxetine with visa, the length of the cervix decreases steadily to a few millimetres when it is fully effaced Cervical dilatation: the increase in diameter of the cervical opening erectile dysfunction doctor miami purchase dapoxetine, measured in centimetres (Figure 11 erectile dysfunction after radical prostatectomy treatment options discount 90 mg dapoxetine mastercard. After this phase how do erectile dysfunction pills work purchase dapoxetine 90mg on line, the cervix dilates rapidly (the active phase) until it is 10 cm (fully dilated) erectile dysfunction treatment natural remedies buy generic dapoxetine pills. The latent phase and the active phase together constitute the first stage of labour erectile dysfunction evaluation dapoxetine 60 mg line. Second stage the second stage of labour begins after full cervical dilatation is reached. Fetal descent through the birth canal occurs towards the latter part of the active phase and after the cervix is fully dilated. Once the fetus touches the pelvic floor, the woman usually has the urge to push (the expulsive phase). Fetal descent Fetal descent may be assessed by abdominal palpation and vaginal examination Abdominal palpation Fetal descent into the pelvis may be assessed in terms of fifths of head palpable above the symphysis pubis (Figures 11. Exclude malpresentations and poor contractions before making a diagnosis of disproportion. Uterine contractions Good contractions are characterized by: A frequency of 2 to 4 in 10 minutes A duration of 30 to 60 seconds Progressive effacement and dilatation in the latent phase Progressive dilatation of at least 1 cm/hour in the active phase Progressive descent of the fetal presentation. If you have excluded malpresentation and labour fails to progress in spite of good contractions, assume the cause to be disproportion. Poor 11 contractions in the latent phase may represent false labour; do not confuse them with abnormal labour. Malpresentations and malpositions the most frequent and most favourable presentation is a well flexed head in the occipito-anterior position. In a malpresentation, there is usually a poor fit between the presenting part and the maternal pelvis. Disproportion If labour persists with disproportion, it may become arrested or obstructed. You may be able to identify disproportion early in some cases: for example, with a hydrocephalic head or a large baby in a woman with an abnormal pelvis because, for instance, of a history of malformation or trauma to the pelvis. In most cases, however, disproportion is a diagnosis of exclusion: that is, after you have excluded poor uterine contractions and malpresentations. When arrested labour is not recognized and becomes prolonged, cephalopelvic disproportion leads to obstruction. Evidence of obstructed labour includes arrested dilatation or descent with: Large caput and excessive moulding Presenting part poorly applied to cervix or cervix is oedematous Ballooning of the lower uterine segment and formation of a retraction band Maternal and fetal distress Prolonged labour without delivery. Check pulse, blood pressure and hydration (tongue, urine output), temperature 11 Does she have any medical problems If the woman has at least 2 uterine contractions lasting more than 20 seconds over 10 minutes, do a vaginal examination to assess cervical effacement and dilatation. If the cervix is not dilated on first examination, it may not be possible to make a diagnosis of labour. At this stage, if there is effacement and dilatation, the woman is in labour; if there is no change, make a diagnosis of false labour. An incorrect diagnosis of labour in this situation can lead to unnecessary anxiety and interventions. Active phase Cervix between 4 cm and 10 cm dilated Rate of cervical dilatation at least 1 cm/hour Effacement is usually complete Fetal descent through birth canal begins. Second stage Early phase (non-expulsive) Cervix fully dilated (10 cm) Fetal descent continues No urge to push. Late phase (expulsive) Fetal presenting part reaches the pelvic floor and the woman has the urge to push Typically lasts <1 hour in primigravidae and <30 minutes in multigravidae. Carry out vaginal examinations at least once every 4 hours in the first stage of labour and plot the findings on the partograph. The partograph is very helpful in monitoring the progress of labour and in the early detection of abnormal labour patterns. Record the actual time on the X axis, corresponding to this point on the Alert line. At each vaginal examination, record the following: Effacement and dilatation Presenting part and station Colour and odour of liquor. Assess progress in labour by: Measuring changes in cervical effacement and dilatation in the latent phase Measuring the rate of cervical dilatation in the active phase Assessing fetal descent in the second stage. Listening more frequently if an abnormality is detected: while the normal fetal heart rate is between 120 and 180 beats/minute, rates of <100 or >180 are suggestive of fetal intolerance of labour or distress. Listening for the fetal heart rate recovery after contractions: repetitive slow recovery indicates fetal distress. Greenish-yellow fluid, blood stained fluid or no fluid are suggestive of placental insufficiency and possibly fetal compromise. Findings suggestive of satisfactory progress in labour Regular contractions of progressively increasing frequency and duration Rate of cervical dilatation at least 1 cm/hour in the active phase of labour Satisfactory descent with pushing in the expulsive phase Cervix closely applied to fetal head. Findings suggestive of unsatisfactory progress in labour Irregular, infrequent and weak contractions Cervical dilatation rate slower than 1 cm/hour in the active phase No descent with pushing in the expulsive phase Presenting part applied loosely to the cervix. Findings suggestive of risks to the fetus Bloodstained amniotic fluid Greenish-yellow coloured amniotic fluid Fetal heart rate abnormalities, such as decelerations, tachycardias or delayed recovery of fetal heart rate after contraction. Mistaking false labour for the latent phase leads to unnecessary induction and unnecessary caesarean section. The latent phase is prolonged when the cervical dilatation remains less than 4 cm after 8 hours. If a woman has been in the latent phase for more than 8 hours, reassess the situation: If there has been no change in cervical effacement or dilatation and there is no fetal distress, review the diagnosis of labour; the woman may not be in labour If there has been a change in cervical effacement and dilatation, augment contractions with oxytocin. Artificial rupture of membranes is recommended along with or before augmentation of labour with oxytocin. Reassess every 4 hours: If the woman has not entered the active phase within 8 hours, consider delivery by caesarean section, but be sure the patient is not in false labour If membranes are already spontaneously ruptured, induce or augment labour without delay In areas of high Group B streptococcal prevalence, give antibiotic prophylaxis starting at 12 hours after rupture of the membranes to help reduce Group B streptococcus infection in the neonate If there is any evidence of amnionitis, augment labour immediately and treat with antibiotics. Slow progress of labour in the active phase of labour may be due to one or more of the following causes: Inefficient uterine contractions Malpresentations and malpositions. When the rate of dilatation in the active phase is slower than 1 cm per hour, reassess the mother for poor contractions or malpresentation: 11 If there is evidence of obstruction, perform a caesarean section If there is no evidence of obstruction, augment labour with amniotomy and oxytocin. Reassess progress by vaginal examination after 2 hours of good contractions: If there is no progress between examinations, deliver by caesarean section If there is progress, continue oxytocin and re-examine after 2 hours. Inefficient, poor uterine contractions are less common in a multigravida, so make every effort to rule out disproportion before augmenting with oxytocin. In the active phase of labour, plotting of cervical dilatation will normally remain on, or to the left of the alert line on the partograph. If a womans labour reaches this line, you will need to make a decision about the cause of the slow progress and take appropriate action. Spontaneous maternal pushing should be permitted, but the practice of encouraging breath-holding and prolonged effort should be abandoned. Prolongation of the expulsive phase may also occur for the same reasons as prolongation of the active phase. If malpresentation and obvious obstruction have been excluded, failure of descent in the expulsive stage should also be treated by oxytocin infusion unless contraindicated. If there is no descent even after augmentation with oxytocin, consider assisted delivery. Assisted vaginal delivery by forceps or ventouse is indicated if the head is engaged (not more than 1/5 of the head is palpable above the pelvic brim) or if the leading bony edge of the fetal head is at 1 cm or more below the level of the ischial spines by vaginal examination. Spontaneous delivery in the posterior position may occur, but labour may be complicated by prolonged first and second stages. Arrested labour Arrested labour may occur when rotation and/or descent of the head does not occur: Ensure adequate hydration Check maternal and fetal condition If there is fetal distress, consider delivery by caesarean section if quick and easy vaginal delivery is not possible If there is still no descent after a trial of labour and the head is engaged and at 1 cm or more below the ischial spines, deliver by forceps or ventouse If the head is >1/5 palpable on abdominal examination, deliver by caesarean section If there is evidence of obstruction or fetal distress at any stage, deliver by caesarean section. Brow presentation Spontaneous conversion to either vertex or face presentation may occur, particularly when the fetus is small or when there is fetal death with maceration. It is unusual for spontaneous conversion to occur in an average sized live baby once membranes have ruptured. When the fetus is dead: If dilatation is incomplete, deliver by caesarean section If dilatation is complete, perform craniotomy or caesarean section. Face presentation Prolonged labour is common with face presentation: In the chin-anterior position, descent and delivery of the head by flexion may occur In the chin-posterior position, the fully extended head is blocked by the sacrum from descent and arrest of labour occurs. Compound presentation (arm prolapsed alongside presenting part) Spontaneous delivery can occur only when the fetus is very small or dead and macerated. Push the arm above the pelvic brim and hold it there until a contraction pushes the head into the pelvis. Breech presentation Prolonged labour is an indication for urgent caesarean section in breech presentation (Figures 11. Transverse lie Caesarean section is the management of choice, whether the fetus is alive or dead (Figure 11. Delivery through a transverse uterine incision may be difficult, especially if the arm is prolapsed or the fetus is back-down, and often results in extension of the incision with laceration of a uterine artery. Sodium citrate works for 20 minutes only so should be given immediately before induction of anaesthesia if a general anaesthetic is given. Choice of anaesthesia In cases of extreme urgency, general anaesthesia can be faster than a spinal and may also be safer if the mother is hypovolaemic or shocked. In lesser degrees of urgency (delivery within 30 minutes required) a well conducted spinal by an experienced anaesthetist minimizes the risk to mother and baby. Opening the abdomen and making the bladder flap the abdomen may be opened by a vertical midline skin incision or a transverse skin incision. Caesarean section under local anaesthesia is more difficult to do with the transverse skin incision. Vertical midline incision 1 Make a 2 to 3 cm vertical incision in the fascia (Figure 11. Place the tip of one blade of a partly open scissors under the rectus sheath and the other blade over the rectus sheath and push laterally to cut the sheath. Opening the uterus 1 Use a scalpel to make a 3 cm transverse incision in the lower segment of the uterus, about 1 cm below the level where the vesico-uterine serosa was incised to bring the bladder down (Figure 11. If the lower uterine segment is thick and narrow, extend the incision using scissors instead of fingers in a crescent shape to avoid extension to the uterine vessels. Make the uterine incision big enough to deliver the head and body of the baby without tearing the uterine incision. Closing the uterine incision 1 Grasp the corners of the uterine incision with clamps. The skin can be closed with a delayed closure later after the infection has cleared. When the baby is breech at caesarean section 1 Grasp a foot and deliver it through the incision. Flex (bend) the head using the fingers of your right hand and deliver it through the incision. When the baby is transverse (sideways) 1 If the back is up (near the top of the uterus), reach into the uterus and find the babys ankles. To repair the vertical incision, you will need several layers of suture (see below). In placenta previa 1 If a low anterior placenta is encountered, incise through it and deliver the fetus. If there is bleeding at the placental site, under-run the bleeding sites with chromic non absorbable (or polyglycolic) sutures. Close the incision using at least three layers of suture: Close the first layer closest to the cavity, but avoiding the decidua, with a continuous 0 chromic non absorbable (or polyglycolic) suture Close the second layer of uterine muscle using interrupted No. Antibiotics Prophylactic antibiotics in caesarean section decrease post operative infection. Induction of labour: stimulating the uterus to begin labour Augmentation of labour: stimulating the uterus during labour to increase the frequency, duration and strength of contractions. A good contraction pattern is established when there are three contractions in 10 minutes, each lasting more than 40 seconds. Induction the success of induction is related to the condition of the cervix at the start of induction: Cervix is favourable if it is soft, short and partially dilated Cervix is unfavourable if it is firm, long and closed: ripen it using prostaglandin or a Foley catheter before induction. Prostaglandin E2 is placed high in the posterior fornix of the vagina and may be repeated after 6 hours if required. Do not insert the catheter if there is a history of bleeding or ruptured membranes or obvious vaginal infection. Membrane rupture, whether spontaneous or artificial, often sets off the following chain of events: Amniotic fluid is expelled. Uterine volume is decreased Prostaglandins are produced, stimulating labour Uterine contractions begin or become stronger. Note and record the consistency, position, effacement and dilatation of the cervix. If the fetal heart rate is less than 100 or more than 180 beats per minute, suspect fetal distress. Oxytocin stimulation Use oxytocin with great caution as fetal distress can occur from hyperstimulation and, rarely, uterine rupture can occur.

Participation rates were 60% for glioma erectile dysfunction products order dapoxetine pills in toronto, 78% for meningioma erectile dysfunction pills canada order dapoxetine in united states online, 78% for neuroma and 75% for controls. For 12 glioma and two meningioma patients information was obtained through proxies. The study found no raised risk of glioma, meningioma or cranial nerve neuroma with regular mobile phone use, and no significant relations of risk to duration of use, cumulative hours of use, mean call length and cumulative number of calls, although for glioma the odds ratios for the top quartile of each of these variables were non-significantly raised (in the range 1. There was no significant relation of risk to side of use: for glioma the odds ratios for ipsilateral and contralateral use were similar, for meningioma that for ipsilateral was slightly higher than for contralateral use, and for cranial nerve neuroma the risk for ipsilateral was lower than for contralateral use. Participation rates were 59% for glioma patients, 78% for meningioma and 51% for controls. Controls were selected by random digit dialling to home fixed-line phones of the general population, individually matched on age, sex and area of residence. This gave a potential for bias in that mobile phone users (or others) with no fixed-line phone would not be included. Acoustic neuroma was presented in a 293 8 C A N C E R S T U D I E S I N H U M A N S separate publication (Takebayashi et al, 2006), where the same study design was used. Interviews were conducted with 101 (84%) acoustic neuroma cases and 339 (52%) individually matched controls. The investigators used a brief non-participant questionnaire for controls who declined to participate in the full interview; this was obtained for just over half of the non-participants. The age and sex adjusted percentage of regular users was marginally higher in the brief questionnaire respondents (66% for the glioma controls and 55% for the meningioma controls) than in the full participants (65% and 51%, respectively). Regular use of a mobile phone was not associated with a significant risk of glioma, meningioma or acoustic neuroma. There were no effects of analogue plus digital phone use or of digital use only (no one used only analogue phones). There was no significant effect of laterality of phone use: for glioma the odds ratio was 1. A subset of glioma cases (99 in total), for whom radiological imaging was available, was included in the analyses. Two neuroradiologists evaluated the radiological images and recorded the midpoint of each tumour on a 1 cm x 1 cm x 1 cm grid. The shortest distance from the midpoint of the tumour to the assumed location of the mobile phone was estimated. Analyses were based on small numbers and, although modestly non-significantly elevated odds ratios were observed for several indicators of mobile phone use, no consistent dose-response patterns were found, with the lowest risk estimates in the highest exposure categories. The study was too small for any conclusions to be drawn, but it has illustrated an innovative method to investigate the potential effect of mobile phone use on glioma risk. The numbers of subjects, age ranges and control sources from the published countries are described above. For Finland, 266 glioma patients, 334 meningiomas and 870 controls were recruited from 98% of the population of the country, ie excluding Northern Lapland and Aland. Participation rates were 81% for glioma patients and 90% for meningioma patients, and 42% for controls. Telephone interviewes were conducted for 3% of glioma patients and 3% of meningioma patients, and 7% of controls. The linear trend in risk with cumulative hours of use was significant when analysed as a continuous variable (1. The risks for cumulative hours of use, and cumulative number of calls, 10 years before the reference date were not significantly raised. There were no increased risks for the use of analogue or digital phones, considered separately, and the results for glioblastoma separately were similar to those for glioma overall as were results for men and women separately. The risks were non-significantly raised for regular reported use of the phone ipsilateral to the tumour (1. Whereas the laterality results overall suggest reporting bias, those for ipsilateral use for 10 years and duration of use are marginally significant and not accompanied by comparable compensatory opposite findings for contralateral use, leaving the possibility of long-term risks. The odds ratio for analogue phones, which generally have greater power output, was not significantly raised, however. When subjects who reported more than 2 hours per day of use were excluded, no relation remained. The combined north European analyses, as for the studies from which they derive, and indeed as for the other Interphone studies considered separately, showed reduced odds ratios for regular use of a mobile phone, no overall evidence for causation of brain tumours by mobile phone use and inconsistently raised risks in relation to the reported cumulative hours of use but not the cumulative number of calls. It should be noted that the hours of use per day, in contrast to the number of calls per day, was a calculated, not a reported, variable. Study subjects were asked about the number and mean duration of calls they made per day on average, and these were then multiplied together to calculate cumulative time per day. There were also some, but not consistent or strong, indications of raised odds ratios for glioma in relation to use 10 years ago. Based on radiological images, neuroradiologists recorded the midpoint of each tumour on a 1 cm x 1 cm x 1 cm grid. The main exposure indicator was the shortest distance between the midpoint of the tumour to the typical location of the mobile phone. To avoid potential recall bias, self-reported laterality of phone use was not taken into consideration when estimating the distance. The distance between the exposure source (ie mobile phone) and the tumour midpoint did not vary with mobile phone use. The distance was slightly shorter in cases who had never used a mobile phone regularly compared with regular users, and among subjects who reported the preferred side of mobile phone use contralateral to the tumour. The distance was longer for cases with the highest cumulative call time and for duration of use >10 years. An accompanying paper describes the details of the exposure assessment (Cardis et al, 2011b). Only cumulative call time and tumour location were significant predictors of the total cumulative specific energy, accounting for 43% and 13% of the variance, respectively. The analyses included 551 glioma cases and 1720 controls, and 674 meningioma cases and 1796 controls. The original matching of controls was not kept; instead a post-hoc matching was performed to take into account differences in the timing of the interview between cases and the original controls. Exposure indices were categorised into quintiles and results were reported for both total cumulative specific energy and cumulative call time. When tumour laterality was not included in the estimation of total cumulative specific energy, to avoid potential recall bias when reporting the preferred side of phone use, the odds ratio was 1. For meningioma, the odds ratio in the highest category of total cumulative specific energy was slightly lower than for cumulative call time, and even lower when tumour laterality was not included. In the <3-year time window, all odds ratios were below unity, except in the highest category of total cumulative specific energy, some of them statistically significantly reduced. Such exposure misclassification is likely to be non-differential, and would therefore dilute risk estimates should an increased risk exist. Estimated total cumulative specific energy is not, however, free from potential recall bias; self-reported information on cumulative call time is the most important determinant of the exposure level, and other factors make only minor contributions to the overall estimate. Results from analyses of cumulative call time were almost identical to those when using the total cumulative specific energy. Analyses of cumulative call time in different time windows before diagnosis were not presented; therefore, it is not possible to assess whether they differ from the corresponding results for total cumulative specific energy in these subgroups. In the time-window analyses of total specific energy by Cardis et al (2011a,b), however, all subjects were included in all time windows. Thus, it is not only the chosen cutpoints that differ between the Cardis et al study and the original Interphone study. This makes comparisons between the Cardis et al study and other studies difficult. In addition, the quintiles used by Cardis et al do not correspond exactly to 20% in each category. For example, for both glioma and meningioma over 24% of controls were in the lowest quintile. One pooled analysis has been conducted with data for acoustic neuroma (Schoemaker et al, 2005). Acoustic neuroma results have been published separately for Denmark, Norway and Sweden (Christensen et al, 2004; Lonn et al, 2004a; Klaeboe et al, 2007). Overall, the pooled analysis included 678 cases of acoustic neuroma and 3553 controls. In the Nordic countries, controls were randomly selected from population registers stratified on sex, age and region. There were no material differences between the results for analogue and digital mobile phone use. Overall, the results do not support an association between mobile phone use and acoustic neuroma risk. The increased risk for 10 years since first use reported in the Swedish study was not confirmed in the pooled analysis. With no overall risk increase in this exposure category, it seems unlikely that the raised risk would reflect causality. Glioma and meningioma: Interphone Study Group, 2010 the Interphone study was set up to provide more powerful analyses of brain tumour (and acoustic neuroma and parotid gland tumour) risk in relation to mobile phone use than any previous study (Cardis et al, 2007; Interphone Study Group, 2010). The questionnaire was administered by interviewers reading the questions from, and entering responses into, an on-screen program on a laptop computer (except in Finland, where a paper questionnaire was used). The interview asked about patterns of use and type of phone (identified by use of show cards) for each phone used, for every respondent who had been a regular phone user, defined as an average of at least one call per week for 6 months or more. In all countries, except France and Japan, the cases were population based; in the latter two countries they were hospital based. Controls were individually matched to cases in seven centres and frequency matched in the remainder. The matching ratio was stated to be 1:1, except in Germany where it was two controls per case. Matching variables were age, sex and region of residence as well as, in Israel, ethnic origin. At the analysis stage, individual matching was conducted post-hoc for centres that had collected controls with stratified matching, to give one control per case (or two in Germany). Risks in relation to deciles of cumulative number and duration of calls were calculated, with the cut-points of the deciles stated to be based on the distribution in controls who were regular users. The study centres interviewed 2765 eligible glioma cases, 2425 meningioma cases and 7658 controls. Because of the use of post-hoc matching, however, only 2708 glioma cases with 2972 controls, and 2409 meningioma cases with 2662 controls, were included in the analyses. In total, 94% of interviews for glioma cases and 95% for controls (not stated for meningioma) were conducted face-to-face, although the percentages were much lower than this in two countries (Italy and Norway) where most interviews were by telephone. Interviews were with proxies for 13% for glioma and <2% for meningioma cases, and 1% for controls. For 11% of glioma and 5% of meningioma cases, and 5% of controls (17%, 9% and 8%, respectively, of regular users), there were missing data regarding mobile phone use for which imputation was used to fill the gaps. Significantly reduced odds ratios of glioma and meningioma were found for regular users of mobile phones. There was no relation of risk to cumulative number of calls or years since first use. For cumulative hours of use there was no appearance of a linear trend in risk (although trend tests were not presented). The individuals with the highest cumulative hours of use included many with highly implausible values of hours per day, who were largely glioma cases: for instance, 10 glioma cases but no controls reported 12 hours of use per day. For each of these locations separately, there were no apparent trends in risk with time since first use, cumulative hours of use or cumulative number of calls; no trend tests were presented. Odds ratios of both glioma and meningioma tended to be greater ipsilateral to the reported side of use of the phone than contralateral: for regular users, odds ratios for glioma were 0. Tests of trend in risk with cumulative call time and cumulative number of calls by laterality were not presented, but there appeared to be a tendency, although not strong or consistent, for odds ratios of ipsilateral meningioma and glioma to be greater at higher levels of these variables. For contralateral tumours, however, odds ratios for all levels of these exposure variables were below 1. The odds ratio for the top decile of cumulative hours for glioma ipsilateral to reported phone use was 1. The risks were not raised for regular use of analogue or digital phones, considered separately. There was no appreciable effect modification by age or sex for any of the above results. Acoustic neuroma: Interphone Study Group, 2011 the Interphone study also investigated acoustic neuroma risks, based on 1105 cases and 2145 controls (Interphone Study Group, 2011). In total, 16 otherwise eligible cases and 5513 otherwise eligible controls were not included in the analyses because of the use of post-hoc matching.
