Anecdotally, experienced injectors have recognized that if complete correction is initially accomplished, the correction per- sists longer.

Over a prolonged period of observation (min- Mechanisms utes to hours), atrial tachycardia cycle length can exhibit important variations. A progressive rate increase at tachycardia onset (warm up)[40] and/or a progressive rate Focal atrial tachycardia is characterized by atrial acti- vation starting rhythmically at a small area (focus) decrease before tachycardia termination (cool down) Eur Heart J, Vol. After the impulse has propagated rapidly in all parts of both atria, an electrical silence follows until the next focal atrial discharge. Rate can bances, intra-atrial activation may extend over a large increase during exercise[41,42]. Typically, adrenergic proportion of the cycle length[43], and conduction spread stimulation can accelerate the rate of focal discharge. This point will be suggesting a reentrant mechanism, constant or progres- further discussed later. Collision of activation fronts and/or partial activation Mapping change during entrainment cannot be demonstrated with multiple endocardial recordings. There activation from the focus or origin may not be uniformly is a clearly dened isoelectric baseline between P waves radial, as conduction can be directed by anatomical or in all leads (Fig. There is generally focus location, and it can be used to approximately an electrically silent period in atrial cycle length that, in localize it before electrophysiological study[36]. Intra-cardiac mapping will show signicant recording can also be used to help localize the site of portions of the cycle length without recorded activity, origin of the tachycardia[44]. In this example of a 16-year-old girl, focal left atrial tachycardia with a cycle length of 480 ms originates in the lateral wall of the left atrium. In the presence of rapid rates and/or intra- pattern (continuous undulation without isoelectric atrial conduction disturbances, P waves can be very baseline). In the late post operative period after atrial septal defect closure, right atrial reentry with a cycle length of 420 ms occurs with the impulse rotating within a protected isthmus which is limited anteriorly by the tricuspid annulus and posteriorly by the atriotomy scar. Macroreentrant atrial tachycardia Mapping Mechanisms the reentry circuit includes large portions of the atria, where continuous, reentrant activation can be recorded the mechanism of macroreentrant atrial tachycardia is with detailed mapping. Activation should be recorded reentrant activation around a large central obstacle, continuously throughout the atrial tachycardia cycle generally several centimeters in diameter, at least in one length if atrial mapping is complete. The central obstacle may consist of ings will often show activation during isoelectric inter- normal or abnormal structures. For illustrative purposes, a particu- cardia mechanisms must be made in relation to atrial lar reference point may be designated as the origin of anatomy, including a detailed description of the activation (time 0), but it should be understood that this obstacles or boundaries of the circuit and the critical is always arbitrary[7,8]. Complex surgical procedures, isthmuses that may be targets for therapeutic action. Typical atrial utter, the most com- record activation throughout the cycle length. However conduction delays ridge)[7,9,10] are reected by recording double potentials within the circuit can prolong the atrial tachycardia (Fig. Double potentials express sequential activation cycle length, making it overlap with the classical focal on both sides of the line of block. The interpretation of ring after radiofrequency ablation and in atriotomy double potentials has to be made in the context of the macroreentrant atrial tachycardia. Double electrograms recorded from the centre of the circuit in a patient with scar macroreentrant tachycardia in the lateral right atrium. The superimposed schema represents a right anterior oblique view of the right atrium, and the clear band represents the scar. The bottom recording in each trace shows double electro- grams along the scarred area from superior to inferior, as marked in the schema. Note the decreasing separation of the electrogram components that become a continuous fraction- ated electrogram close to the inferior vena cava (L5), suggestive of local slow conduction. Mul- recorded from at least two atrial pacing sites, separated tiple component (fractionated) electrograms may be by at least 2 cm[17,48]. The entrainment cycle length recorded at sites of local conduction disturbances and/or should be of sucient length to prolong conduction, slow conduction[47]. Voltage mapping may be useful in which would result in a prolonged return cycle length, post surgical atrial tachycardia and in patients with even when pacing from within the circuit (Fig. Areas of low or absent local other hand, a very long entrainment cycle length makes electrogram amplitude in the bipolar mode represent it harder to recognize fusion/endocardial activation scar or patch material. The best characterized macroreentrant atrial tachy- cardias are typical (or isthmus dependant) atrial utters and atriotomy (or incisional) atrial tachycardia. Left Transient entrainment atrial macroreentrant atrial tachycardia are less well known due to the need for transeptal catheterization for Transient entrainment is possible in the vast majority of left atrial mapping. Some circuits are very unstable and pacing cycle length should be as close as possible to baseline cycle length in these cases. Mapping during typical atrial utter in a patient with severe local intra-atrial conduction disturbances. The distance between the two components of the rst double potential electrogram is 170 ms. The interval between A and B increases to 260 ms in the second double potential electrogram. In this sequence a 3:2 Wenckebach pattern of block occurs between A and B as marked by the arrows. This shows that this second component is not necessary to the atrial utter maintenance. A similar phenomenon is shown in the lower panel where a 2:1 block now occurs between the two components of the double potential electrogram at a slightly distant site. However, there is information suggesting some patients and of a functional nature in others[51,52], that in some cases, activation can also cross the superior and occurs in the region between the venae cavae end of the crista terminalis[56] or even lower along this perhaps due to anisotropy. The inferior pivot point is the area bounded corded at multiple levels in the region of the crista anteriorly by the inferior part of the tricuspid orice, terminalis[5,6,9]. Double potentials circuit (90% of clinical cases) is in the descent in the case are also recorded along the eustachian ridge[9,10]. This has isthmus, sub-eustachian isthmus, inferior isthmus, or been described as counterclockwise reentry, when simply utter isthmus. Complete transection or ablation viewed from a left anterior oblique, uoroscopic per- of this isthmus interrupts and prevents typical atrial spective. Localized activation change can be detected by data suggest that in most cases it includes the multiple endocardial recordings, even in the absence of Eur Heart J, Vol. The left panel shows the end of entrainment at 250 ms cycle length, and the right panel at 220 ms cycle length. The baseline activation sequence, which recurs after pacing, shows coronary sinus activation from distal to proximal preceding the septal right atrium. A return cycle length occur clinically in the typical atrial utter circuit in after transient entrainment is equal to baseline cycle 10% of cases[2,64]. This is still called typical atrial utter length (<20 ms dierence) when pacing the utter because the reentry path is the same, even though the isthmus, right atrial roof and anterior and septal right direction of activation is reversed. This consists of in typical atrial utter are detected in reverse typical a downsloping segment, followed by a sharper negative atrial utter: double potentials are recorded at multiple deection, then a sharp positive deection with a posi- levels in between the venae cavae, and the eustachian tive overshoot leading to the next downsloping plateau. As in typical atrial utter, complete tran- the relative size of each component can vary markedly. Recordings along the lateral wall are made by means of a duodecapolar halo catheter from top (H17-18) to bottom i. Pacing is initiated within the atrial utter isthmus via the distal bipole of the halo catheter. The rst cycle following pacing cessation is identical to the atrial utter cycle length, conrming isthmus dependence of the atrial tachycardia. During entrainment as well as during ongoing utter, the activation is descending in the right atrial wall (arrows). Fixed block is Reverse typical atrial utter can be recognized with a present in the central obstacle and double potentials high degree of reliability in the presence of broad, are recorded at linear scar lines (Fig. Wide negative deections in V1 may be Very complex and/or multiple reentry circuits can be the most specic diagnostic sign[65,67] (Fig. After placement of an intra-atrial bae to treat trans- position of the great vessels, it may be impossible to map Lesion macroreentrant atrial tachycardia the entire circuit, due to the complex suture lines and baes. Entrainment becomes an essential tool in these In this macroreentrant atrial tachycardia, the central cases to conrm participation of specic areas in the obstacle of the circuit is an atriotomy scar, a septal circuit and to try to locate a suitable isthmus area from which concealed entrainment[72] can be demonstrated. Multiple endocardial record- of scar and at bipolar recordings characterizing the ings can help by showing local activation change (surrogate of fusion) during entrainment[20]. It is often followed by a positive notch that is synchronous with the positivity in V1 and then by a slightly descending plateau. In the majority of the cases, the atrial utter waves are described as predominantly positive in the inferior leads and negative in lead V1. The line of double potentials or fractionated, low voltage V electrograms can also often be recorded in sinus rhythm 1 allowing tentative localization of the scar and the V2 associated anatomical isthmuses. Typical atrial utter is often associated with right V3 atrial atriotomy tachycardia[49]. Not uncommonly, ablation of one will unmask the other, and ablation of both circuits will be necessary for clinical success. The recording of multiple V simultaneous electrograms, as continuous endocardial 5 V references, will facilitate detection of these activation 6 changes. In this case large notches are incisional macroreentrant atrial tachycardia can range superimposed on the atrial utter waves, which exhibit a more balanced undulating pattern, but are still from that which is similar to typical atrial utter, to that predominantly negative in V. This deserves a separate description because it is the simplest model, is relatively common and relatively easy to study and ablate. Other macroreentrant tachycardias of the the anterior right atrial wall is commonly activated right atrium supero-inferiorly (descending), as in typical atrial utter. However, the septal wall frequently lacks a clear cut Some unusual macroreentrant tachycardias appearing infero-superior (ascending) activation pattern. Partici- either after ablation or pacing in patients with typical pation of the anterior right atrial wall in the circuit can utter have been characterized. A line of double potentials is posterior arm is the low posterior right atrial wall with recorded in the lateral right atrium, extending supero- conduction across the crista terminalis, making it a inferiorly. Double potential separation can be more variant of typical atrial utter in which the superior turn marked, and demonstrate a voltage lower than in typical around is lower[57]. These isthmuses can be areas of another macroreentrant tachycardia in which two wave- slow conduction (Fig. Stable pacing of the critical fronts circulate simultaneously in the same reentrant Eur Heart J, Vol. Positioning the catheter at this site reproducibly interrupted the macroreentrant tachycardia (probably by mechanically induced depolarization). Note that, although late, the local electrogram is slightly advanced at the time of tachycardia interruption without any discernable change in the timing of the other electrograms, further supporting the critical role of this area. In this example, right atrial reentry with a cycle length of 490 ms occurs with the impulse rotating around the atriotomy scar. Entrainment of left atrial macroreentrant tachycardia with circular counterclockwise right atrial activation after isthmus ablation for typical atrial utter. Anterior wall activation is descending and septal activation ascending, as in typical counter- clockwise atrial utter. The return cycle length after pacing is long in all right recordings but equal to the baseline cycle length in the coronary sinus recordings. To date, it has only been described as using In the absence of left atrial mapping through tran- the typical reentrant circuit. It is an unstable rhythm, septal catheterization, long segments of cycle length may and generally of brief duration. Left atrial recordings can be obtained from the coronary sinus, the oesophagus and the pulmonary arteries to Left atrial macroreentrant atrial tachycardia help ll these gaps in activation. Right atrial mapping typically shows non-reentrant A stable macroreentrant atrial tachycardia can originate activation patterns, clearly dierent from typical and in the left atrium. The activation reports have characterized the substrate as showing wide sequence of the coronary sinus is typically from distal to scarred areas with low voltage or absent electrograms[84]. Endocardial activation mapping shows that during atrial utter, activation proceeds from the distal to the proximal coronary sinus, and then to the infero lateral wall of the right atrium. The higher portion of the lateral wall of the right atrium is depolarized in a descending fashion, presumably after activation via the Bachman bundle. H19-20 to H1-2 represent recordings from a halo catheter in the right atrium in the usual position. In these cases the response to Atypical atrial utter/tachycardia pacing (entrainment) will clarify location of the re- entrant circuit (Fig. A long local return cycle length With reference to our proposal of typicality, the term after pacing the low anterior, low septal and low isthmus atypical atrial utter should be dened as any tachycar- excludes participation of these areas in a reentry circuit.

A range of validated scales were used and a treatment utilisation scale was created knee pain treatment kansas city purchase ibuprofen cheap online. Hierarchical multiple regression and structural equation modelling were used to identify predictors of symptom severity and treatment utilisation pain medication for dogs cancer discount ibuprofen 400mg free shipping. A sub-sample of 30 women from study 2 went on to participate in study 3 which was a qualitative study designed to explore how beliefs about menopause influence symptom perception and decisions about treatment in the context of womens daily lives pain and spine treatment center dworkin buy ibuprofen with visa. Diaries were completed and used in interviews in study 3 to enable more accurate recall of the social context of menopause events pain after zoom treatment discount 400mg ibuprofen overnight delivery. Ninety one percent of the women in this study had sought treatment for menopause symptoms and the main predictors of treatment utilisation was symptom severity and the belief that menopause was a pathological illness treatment for shingles pain management buy ibuprofen without prescription. A key finding was that four social constructions of menopause were prevalent in this sample: menopause renders women invisible and unvalued pain management utica mi order 600mg ibuprofen fast delivery, menopause is an illness that changes women, menopause is amenable to treatment with hormone therapy, and menopause is a temporary phase after which there is recovery. These four beliefs were significantly predictive of perceptions of symptom severity and of treatment utilisation. Furthermore, the social constructions mediated between symptom severity and different categories of treatment utilisation. Qualitative analysis revealed that women have inadequate knowledge of menopause and can be surprised and distressed by its onset, menopause is little talked of and is still taboo, menopause is regarded by women as a significant phenomenon that changes them but this is not often acknowledged publicly, women and clinicians have difficulty in making attributions to menopause and neither women nor clinicians are able to define normality at menopause. These findings have major implications for how women interpret their symptoms, for how to manage the expectations of women in their 40s and 50s, and for how clinicians advise women at this stage of their life. This dissertation is the result of my own work and includes nothing that is the outcome of work done in collaboration. Although it was not exactly starting with a blank sheet, there were few other researchers working in the same field, with consequently few experienced voices to draw on. Dr Juliet Foster has been unerringly helpful, making just the right interventions at just the right time. Professor Melissa Hines acted as my faculty advisor and read through and made insightful comments on this research at various stages of development. Professor Mark Haggard patiently taught me everything I needed to know about advanced statistics and structural equation modelling and Jan Sirk- Sadowski offered assistance when computer programs refused to behave as they should. Mr Nick Panay, who was, at the time, Chairman of the British Menopause Society, supported the study and enabled me to gain access to clinical patients. I am particularly indebted to the women who participated in this study for giving up their time and being prepared to give me a great deal of often personal and sensitive information. Interaction Effects of Social Support on Biomedical and Non-biomedical Treatment Utilisation, 128 8. This is a much greater ratio than for other, less prevalent aspects of the human female reproductive cycle. The ratio of medical to socio- psychological articles about childbirth was 17 to 1 and for pregnancy the ratio was 16 to 1. The fact that there is less psychological research about a topic may simply mean that there are no major psychological issues of interest. However, the majority of women report that they experience symptoms, and a significant minority report that these are severe. For example, approximately three-quarters of women report hot flushes and night sweats at menopause, and up to one-fifth of these women perceive them to be severe and problematic (Bruce & Rymer, 2009; Dennerstein, Dudley, Hopper, Guthrie, & Burger, 2000; Nelson, 2008). Assuming that it is possible to identify an agent that causes the physical disturbances and then find a treatment, the problems should disappear. In the case of menopause, the causal agent had been identified as estrogen and progesterone as long as ago as 1932 (Geist & Spielman, 1932) and the use of hormone therapies had been widely available in the West from at least the 1960s (Wilson, 1966). Hormone therapy usage became increasingly prevalent among women in their 50s in the West from the 1960s to the late 1990s. However, there was a dramatic decline in both usage and prescribing after two major epidemiological studies reported in the early 2000s that prolonged use of artificial hormones could lead to elevated rates of some cancers and thromboembolisms (Million Women Study Collaborators, 2003; Writing Group for the Womens Health Initiative Investigators, 2002). Despite the focus on hormones as a causal factor, there has been recognition that menopause is not only a biological experience: a range of social and psychological factors also influence the symptom experience at menopause (Ayers, Forshaw, & Hunter, 2010; Hunter & Rendall, 2007). Some studies have suggested that attendance at a clinic is better predicted by psychological rather than somatic symptoms (Hunter, 1988). However, there are relatively few studies that have identified how those factors together contribute to the perception of symptom severity, or indeed treatment utilisation. Most studies examine 1 only one aspect of psycho-social influence, such as personality (Elavsky & McAuley, 2009), social functioning (Montero, Ruiz, & Hernandez, 1993) or stress (Igarashi et al. Moreover, the majority of studies have been conducted with clinical patients, so there has been concern that these may not be applicable to non-patient populations (McKinlay, McKinlay, & Brambilla, 1987; Morse et al. One possible reason for the lack of socio-psychological studies on menopause is that menopause has never had a good press and perhaps as a result it has not been regarded as of great import. Menopausal women have been described as borderline pathological, being regarded as unstable in both body and mind (Foxcroft, 2009, p. Historically, menopause has been routinely portrayed as a time when women were expected to become ill, depressed, unattractive and less sexually desirable, and the predominant discourse in the West tended to portray menopause as a stage in life that was associated with the inevitable process of aging and illness (Chrisler, 2008). Whilst there was a backlash against such portrayals among feminist researchers (Dillaway, 2005; Lock, 1991; Perz & Ussher, 2008; Posner, 1979), it is interesting to question to what extent these socially constructed ideas of menopause have been dispelled and whether, if they still exist, they exert an influence on the perceptions of the experience. The final reason for embarking on this study was an observation by the author when working on an earlier study that women could report very severe symptoms but some would decide to seek biomedical treatments whereas others reported equally severe symptoms but preferred to try and deal with the situation as best they could without resorting to drugs (Rubinstein & Foster, 2012). What could account for these differences and why were some women more resilient than others On this basis, the following broad aims were identified (i) to explore how women make sense of menopause, (ii) to assess which factors predict perceptions of symptom severity, (iii) to assess which factors predict treatment utilisation, and (iv) to explore how beliefs about menopause are located within the social context of their daily lives. An important component of understanding how women make sense of menopause was to identify the social constructions of menopause that were prevalent in our culture and the extent to which they contributed (if at all) to the symptom experience and to treatment uptake. The main outcome measures were symptom severity and overall level of treatment utilisation which was further divided into biomedical and non-biomedical treatment utilisation. The reason for this design was that the research questions were distinctive but interlinked: the need to quantify the relative contribution of bio-psycho-social factors called for a quantitative approach but the need to understand the meanings of menopause and the mechanisms by which these might operate called for a qualitative approach. Study 1 was a survey to develop new measures of to assess womens beliefs about menopause, Study 2 was a broader survey which was designed to assess which factors predicted symptom severity and treatment 2 utilisation. Questions covered sociodemographics, lifestyle, general health, the experience of menopause, treatment utilisation for menopause symptoms, along with psycho-social variables including perceived social support, personality traits, coping approaches and social constructions of menopause. Where possible, validated scales were used but the social construction scales and the treatment utilisation scales were developed specifically for this study. Study 3 was a qualitative study where selected women from study 2were given diaries to keep for eight days, after which time they were interviewed. The reason for doing the research in this order was that there was no pre-existing scale for treatment utilisation and it was necessary to ensure that women were selected to represent the range of treatment utilisation from low to high. The range of this scale could not be identified until after the quantitative survey was completed. The intention was to recruit from a representative group of women who were menopausal. To this end, the age range was specified as 40 to 60 years of age to ensure that women who were just entering menopause as well as those who had been through it could be studied. In order to ensure that women from different socioeconomic groups and ethnicities were recruited, the study locations chosen were Cambridge and Nottingham. In the event, the sample was better educated and of a higher socioeconomic status than intended. The women were not attending the surgery specifically because they wanted treatments for menopause. A clinical sample was recruited through two specialist clinics at London hospitals to ensure that there was the opportunity to understand what caused some women to seek this level of biomedical treatment. Site agreements were given to conduct the research at Queen Charlottes and the Chelsea and Westminster Hospitals. The structure of this thesis: Chapters 2 to 4 describe the existing literature from different perspectives and defines the gaps in knowledge. Chapters 7, 8 and 9 report the results of the three studies, followed by Chapter 10: Discussion; and the Conclusions and Implications are reported in Chapter 11 Chapter 2 focuses on the biological aspects of the menopause. It outlines the pathophysiology of menopause, describes the changes at menopause, what is known about symptom prevalence, and theories as to the mechanisms by which these symptoms occur. Whilst declines in estrogen are always implicated in the genesis of symptoms, the precise mechanisms that cause these symptoms are not clear. The brain adaptation hypothesis has been put forward as a reason for why some women seem better able to adjust to the fluctuations in hormones but again, this mechanism is not understood (Deecher & Dorries, 2007). These are discussed in the context of illness representations and of different theories of coping. This chapter highlights that women have long believed they receive confusing and contradictory information about menopause, and that health beliefs and illness representations of menopause are important in determining symptom severity and whether or not treatment is sought. However, health beliefs about menopause and representations of menopause have rarely been investigated. Chapter 4 reviews what is known about the social constructions of menopause in non-western and western societies. It traces the rise in the biomedical discourse of menopause as a precursor to disease and to treatment. Other types of constructions are also apparent, including a construction of menopause as a symbol of aging, and menopause as just another stage of life (Gannon & Stevens, 1998; Hvas & Gannik, 2008; Jones, 1994). There is a suggestion that a new discourse of confusion is emergent that attempts to smooth over the tensions between the disease and the natural constructions (Lyons & Griffin, 2003). However, research in this area has been mainly small scale and qualitative and so it is extremely difficult to know how prevalent these beliefs currently are. The review of the literature in Chapters 2 to 4 revealed several important gaps in our knowledge about menopause including a lack of research investigating the influence of health beliefs, as well as the lack of an empirical evaluation of social constructions of menopause. Furthermore, it is apparent that much of the research has been with clinical populations and we know little about the daily lived experiences of women from non- patient populations. The methods chosen were in accordance with the principles outlined by Dennerstein & Holmes (2000): research about complex issues that affect womens health should use a broad approach and take account of social factors and the role of culture. They suggested that the study should be described as a general health survey so that bias caused by emotional responses to menopause is lessened. They also recommended that information on current symptomatology be collected, to minimise the problem of recall bias and to ensure that the age range encompasses the menopausal transition. In addition, Dennerstein & Holmes recommend that validated scales are used and hence the Menopause Rating Scale (Heinemann et al. Chapter 6 describes the analytical strategy used for studies 1, 2 and 3 and describes the data preparation that was required before conducting analyses. This section outlines the instruments used in studies 1 and 2, and the qualitative approach of thematic analysis for study 3. One hundred and forty nine women aged between 40 and 60 years of age completed a questionnaire about symptom severity and beliefs about menopause. The data was factor analysed resulting in four latent variables which defined prevalent beliefs about menopause. Chapter 8 describes Study 2 - a quantitative study to assess the predictors of symptom severity and treatment utilisation. Three hundred and forty four pre-, peri- and postmenopausal women1 were included in the analysis. This chapter describes the preliminary analysis comparing clinical and general population samples and the regression modelling and structural equation modelling used to identify predictors of symptom severity and treatment utilisation. The main findings from study 2 were that 91% of the women in this study had sought treatment for one or more menopause-related symptoms, and that biomedical treatments were the most prevalent category of treatment for all the symptoms reported. Four social constructions of menopause were confirmed: a belief that menopause is an illness that changes women; a belief that menopause is amenable to treatment with hormone therapy; a belief that menopause renders women invisible and unvalued; and a belief that menopause is a temporary phase after which there is postmenopausal recovery. These constructions had significant, direct effects on symptom severity and treatment utilisation, and were also significant mediators between symptom severity and treatment utilisation. The belief that menopause is amenable to treatment with hormone therapy influenced biomedical treatment utilisation and the belief that menopause is a temporary phase after which there is postmenopausal recovery influenced non-biomedical treatment utilisation. The regression analyses indicated that there were multiple, interrelated predictors of treatment utilisation, and the structural equation model showed that the pathway to treatment utilisation had to go through perceived symptom severity. That is, there were several factors that were significantly predictive of symptom severity and perceived symptom severity was the main predictor of the level of treatment utilisation. The main predictors of symptom severity included levels of Health wellbeing, prior illness, menopause stage, the number of attributions made to menopause, and emotional stability. Believing that menopause was a pathological condition was predictive of treatment utilisation, even when controlling for other variables. Premenopausal women were defined as currently menstruating or using birth control. Perimenopausal women were defined as experiencing noticeable changes in the length, duration or amount of flow in the menstrual cycle. Postmenopausal women were defined as not having experienced a period for 12 months or more. The hypothesis that women who rate lower for treatment utilisation will be more likely to construct menopause as a natural stage was only partially supported, and the hypothesis that women who rate higher on treatment utilisation will have fewer coping strategies was unsupported. Chapter 9 describes study 3 - a qualitative study designed to explore how womens beliefs are situated within the social context of their daily lives. One hundred and ninety-four women (53%) from study 2 volunteered to participate in study 3. This is a surprisingly high proportion and indicated that this was a topic women were keen to discuss. A comparison of volunteers and non- volunteers indicated that the main difference between these groups was that volunteers scored more highly on symptom severity on average. Thirty women were selected for study 3 to represent a range of treatment utilisation. As one of the aims was to reflect the daily lived experiences of menopause and locate them within their social context, study 3 used diaries and interviews to allow women to describe their feelings in detail.

However, a positive family history for febrile seizures or idiopathic epilepsies was repeatedly reported (4). Altogether, classification as an idio- pathic generalized epilepsy syndrome seems unequivocal.

Seizures may occur repetitively, but usually only in done by Dravet and Bureau (11). Doose and coworkers reported that in about 20% the seizures have their onset during the first year of life (7,16). Today, many authors feel that onset before the second year of life is exceptional. Like most other myoclonic epilepsies of early childhood, it affects more boys Background activity is normal. Some days or short weeks later, myoclonic and/or myoclonic-astatic seizures set in in abundance, frequently in combination with brief absences. Tonic axial seizures may manifest during long-term course, fre- quently occurring during sleep. Myoclonic seizures consist of symmetric, mostly generalized jerks, accentuated in the arms and the shoulders, and are frequently associated with a simul- taneous flexion of the head. The intensity of these seizures is variable and ranges from violent myoclonic jerks with sudden falls to abortive forms merely presenting as short irregular twitches of the face. Myoclonic-astatic seizures are character- ized by a loss of muscle tone preceded by a (short) myoclonia.
