Neck Pain in Adolescent Headache Sufferers. A Cohort Study of Schoolchildren

Although neck pain (NP) and headache (HA) are often concomitant in adolescents, few data exist on the association of NP with HA in this age group. The aim of the study was to examine the association of concomitant NP with adolescent HA and with the outcome of HA. The associations of self-reported NP, physical findings of the neck and disc degeneration of the cervical spine with adolescent HA were studied. This study is part of a population-based follow-up study of 12-year-old children (N 1135/1409) with and without HA. A sample of adolescents (N = 304) was followed to the age of 16 years. At the age of 17 years, 69 of them participated in a magnetic resonance imaging (MRI) study of the cervical spine. During the follow-up from 13 to 16 years of age, changes in both HA type and frequency were common. A poor outcome of HA was associated with NP interfering with daily activities at the age of 13 years. The changes in HA type were not predictable by NP. At the age of 16 years, local and referred palpation pain of the neck muscles, self-reported NP and NP intensity were associated with HA, and especially with disturbing HA unresponsive to analgesics. The association of NP with HA was not determined by HA type. Mild degenerative changes of the cervical spine were common but did not contribute to headache. HA in adolescence is often episodic, and prevention and treatment of NP could be important in the prevention of future chronic adult HA.

Neck Muscle Function and Adolescent Headache

Muscular function of the neck region may be of importance for the etiology of headache, especially of tension-type headache. However, very few data exist on the association of neck muscle function with different types of headache in adolescents. The main aim of the study was to examine the association of neck muscle function with adolescent headache. The associations between leisure time activities, endurance strength of the upper extremities (UE endurance) and mobility of the neck-shoulder region and adolescent headache were studied. In addition, the associations of force production, EMG/force ratio, co-activation and fatigue characteristics, and cross-sectional area (CSA) of neck muscles with adolescent headache were studied. The study is part of a population-based cohort study of 12-year-old children with and without headache. The study had five phases (years 1998-2003). At the age of 13 years, a sample of 183 adolescents (183/311) participated in endurance strength and mobility measurements of the neck-shoulder region. In addition, the type and level of physical and other leisure activity were elicited with open and structured questions. At the age of 17 years, a random sample of 89 adolescents (89/202) participated in force and EMG measurements of the neck-shoulder muscles. In addition, at the age of 17 years, a sample of 65 adolescents (65/89) participated in CSA measurements of the neck muscles. At the age of 13 years, intensive participation in overall sports activity was associated with migraine. Frequent computer use was associated both with migraine and tension-type headache. The type of sports or other leisure activity classified them on the basis of body loading was not associated with headache type. In girls, low UE endurance of both sides, and low cervical rotation of the dominant side, were associated with tension-type headache, and low UE endurance of non-dominant side with migraine. In boys, no associations occurred between UE endurance and mobility variables and headache types. At the age of 17 years, in girls, high EMG/force ratios between the EMG of the left agonist sternocleidomastoid muscle (SCM) and maximal neck flexion and neck rotation force to the right side as well as high co-activation of right antagonist cervical erector spinae (CES) muscles during maximal neck flexion force were associated with migraine-type headache. In girls, neck force production was not associated with headache types but low left shoulder flexion force was associated with tension-type headache. In boys, no associations were found between EMG and force variables and headache. Increased SCM muscles fatigue of both sides was associated with tension-type headache. In boys, the small CSA of the right SCM muscle and, in girls, of combined right SCM and scalenus muscles was associated with tension-type headache. Similarly, in boys, the large CSA of the right SCM muscle, of the combined right SCM and scalenus muscles, of the left semispinalis capitis muscle, of the combined left semispinalis and splenius muscles was associated with migraine. No other differences in the CSA of neck flexion or extension muscles were found. Differences in the neuromucular function of the neck-shoulder muscles were associated with adolescent headache, especially in girls. Differences in the cross-sectional area of unilateral neck muscles were associated with headache, especially in boys. Differences in the neuromuscular function and in the cross-sectional area of the neck muscles also occurred between different types of headache. It remains to be established whether the findings are primary or secondary to adolescent migraine and tension headache.

Aggression and its Management in Adolescent Forensic Psychiatric Care

The overall goal of this study was to explore and identify good aggression management methods and on that basis to produce recommendations for aggression management in the adolescent forensic setting. The study was conducted in three phases. In Phase I, staff’s (n = 58) perception of adolescent aggressive behaviour and methods to manage it was examined. In Phase II, staff’s (n = 30) perception of treatment settings and treatment interventions available were studied. In Phase III, the effectiveness of an aggression management programme was evaluated. The data were collected during the period 2004-2007. Participants perceived adolescent aggressive behaviour in a similar way and described aggressive behaviour as being a comprehensible phenomenon. Management methods used to control aggressive situations were alike, although the practical solutions varied between the study units, especially regarding coercive methods. Staff members proposed more time and better opportunities to discuss and evaluate the aggression situation in order to improve the methods used. The treatment settings were similar in studied forensic units and interventions were primarily focused on psychological aspects, including management of aggressive behavior. A comprehensive aggression management programme proved to be effective in decreasing incidents of violence. The use of coercive methods in aggression situations decreased and injuries to the staff became less frequent. If staff members intend to apply high quality management methods in aggression situations they have to share a consistent understanding of aggressive behaviour and need to be aware of the various methods available. In addition, they should learn more about assessment methods in order to improve aggression management. International comparison of aggression, methods for managing it and service provision creates a starting point for developing equal care provision and realization within and between European countries.

Pregnancy and periodontium. A clinical, microbiological, and enzymological approach via a longitudinal study

The mechanisms leading to an enhanced susceptibility to gingivitis in pregnant women have not yet been completely described. Therefore, the current study series were performed to investigate longitudinally the influence of pregnancy on periodontal tissues, and to evaluate microbial and host response factors related to pregnancy gingivitis formation. Pregnancy-related periodontal changes were analysed in 30 generally healthy women (24- 35 years old) once per trimester, till the end of lactation. Matched non-pregnant women (n=24) served as the controls, and were examined three times, once per following month. Pregnancy-related gingival inflammation was observed as enhanced tendency towards gingival bleeding and pseudopocket formation with a concomitant decrease in plaque levels. Gingivitis reached its peak during mid-pregnancy and then decreased transiently visit by visit. After lactation, no differences in periodontal status were seen between the study and control populations. In contrast to previous studies reporting increased levels of Prevotella intermedia, a specific aim was to analyse phenotypically two identical species, P. intermedia and Prevotella nigrescens, separately using a 16S ribosomal DNA-based PCR. As a result, the increased levels of P. nigrescens were related to pregnancy gingivitis. Matrix metalloproteinases (MMPs) are involved in periodontal destruction. However, their role in pregnancy gingivitis is not well studied. Therefore, neutrophilic enzymes and proteinases, such as MMP and myeloperoxidase (MPO) levels were analysed from saliva and gingival crevicular fluid (GCF) samples during the follow-up. Despite increased inflammation and microbial shift towards anaerobes, the host response did not activate the MMP, elastase and MPO secretion during pregnancy. These results demonstrate that during pregnancy gingival inflammation is enhanced especially during the second trimester, when P. nigrescens levels in subgingival plaque were increased, whereas the neutrophilic enzymes and proteinase levels in both saliva and GCF remained low. These findings could explain, at least in part, why pregnancy gingivitis itself does not predispose or proceed to periodontitis.

Containment Measures in Adolescent Psychiatric Care - Focus on Mechanical Restrain

Rajoitetoimet, erityisesti sitominen, nuorisopsykiatrisessa hoitotyössä Tutkimuksen tavoitteena oli kuvata ja syventää tietoa rajoitetoimien, erityisesti sitomisen, käytöstä nuorisopsykiatrisessa vastentahtoisessa osastohoidossa. Tutkimuksen tavoitteena oli kuvata hoitajien, lääkäreiden ja potilaiden asenteita eri rajoittamiskeinoja kohtaan nuorisopsykiatrisessa osastohoidossa, kerätä tietoa yhden vuoden aikana tapahtuneiden sitomisten määrästä ja luonteesta sekä kuvata potilaiden kokemuksia sitomisesta nuorisopsykiatrisen osastohoidon aikana. Tutkimus tuottaa arvokasta tietoa korkeatasoisten sitomiskäytäntöjen kehittämiseen nuorisopsykiatrisessa osastohoidossa, sekä sitomisten määrää vähentämällä että sitomistapoja kehittämällä. Tavoitteena on parantaa sidottujen potilaiden kliinistä hoitoa. Tutkimusaineisto kerättiin suomalaisilla, pääkaupunkiseudulle sijoittuvilla, nuorisopsykiatrisilla osastoilla neljässä vaiheessa lokakuun 2009 ja huhtikuun 2012 välisenä aikana. Helsingin ja Uudenmaan sairaanhoitopiirin (HUS) nuorisopsykiatrian erikoisalan seitsemän suljetun osaston hoitohenkilökunta sekä lääkärit suhtautuivat myönteisesti rajoittamistoimenpiteisiin. Nuorisopsykiatriset potilaat suhtautuivat rajoittamistoimenpiteisiin kriittisemmin kuin henkilökunta. Nuoret suhtautuivat myönteisimmin tarvittaessa annettavaan lääkitykseen, ajoittaiseen tarkkailuun ja kulun rajoittamiseen. Vähiten hyväksytty menetelmä oli verkkosänky. Nuoret arvioivat sitomisen kolmen vähiten hyväksytyn menetelmän joukkoon. Sitomisen esiintyvyys ja pitkien sitomisten määrä olivat korkeita tutkimukseen valituissa yksiköissä. Useimmat sidotut nuoret tiesivät syyn sitomiseensa, suhtautuivat siihen ambivalentisti nähden siinä sekä hyötyä että haittaa, pitäen sitä kuitenkin rangaistuksena. Huolimatta tästä, suurin osa haastatelluista nuorista koki, että joissain tilanteissa sitomista tarvitaan nuorisopsykiatrisessa osastohoidossa. Nuorilla oli monia ehdotuksia, kuinka parantaa sitomista käytännön osastohoidossa. Tämä väitöskirja tuottaa uutta tietoa eri rajoittamistoimenpiteiden ja sitomisen toteuttamisesta nuorisopsykiatrisessa osastohoidossa. Käytännön hoitotyön parantamiseksi nuorisopsykiatrisilla osastoilla tarvitaan laaja-alaista ja syvälle luotaavaa koulutusta, jotta rajoittamis-toimenpiteiden määrää voidaan vähentää. Myös kriisitilanteiden hallintaan tarvitaan uusia keinoja. Tietoa, kuvausta toimenpiteistä ja tilanteiden käsittelyä jälkikäteen tulee tarjota ala-ikäiselle potilaalle hänen kehitystasonsa huomioiden. Sitomisten määrää tulee vähentää ja niiden kestoa lyhentää. Nuorten tulee olla aktiivisesti mukana kehittämässä aggression hallintamenetelmiä suomalaisessa nuorisopsykiatrisessa osastohoidossa.

Smoking during pregnancy and fetal brain development

Background: Although the knowledge of adverse effects of smoking during pregnancy has increased in recent years, more research is needed to gain a better understanding of the effects of smoking during pregnancy. Smoking exposure is the most common preventable factor that causes adverse pregnancy outcomes. Aims and Methods: First, data on smoking habits during pregnancy from the Nordic Medical Birth Registers was used to study the national differences in trends of smoking during pregnancy. Second, the effects of prenatal smoking exposure on fetal brain development, assessed by brain MRI at term age, were studied by using data from the multidisciplinary PIPARI Study consisting of a 6-year cohort of VLBW/VLGA infants (n = 232, of which 18.1% were exposed to prenatal smoking) born in Turku University Hospital, Finland. Third, the effects of prenatal smoking exposure on psychiatric morbidity and use of psychotropic medication were studied in a cohort of children born from 1987–1989 in Finland (n = 175,869, of which 15.3% were exposed). The data used were obtained from population-based longitudinal registers from the National Institute of Health and Welfare, the Statistics Finland, and the Finnish Social Insurance Institution. Results: Smoking rates during pregnancy differed considerably between the countries. Smoking rates were highest among teenagers and women with lower socioeconomic positions. The smoking prevalence was found to be increasing among teenagers in both Finland and Norway. Prenatal smoking exposure was associated with smaller frontal lobe and cerebellar volumes in preterm infants. A clear association was found between prenatal smoking exposure and psychiatric morbidity treated with specialized hospital care and the use of various psychotropic medications. Conclusions: Prenatal smoking exposure had adverse effects on fetal brain development. These effects might explain part of the association found between smoking exposure and psychiatric problems in later life. Our study suggests that prenatal smoking exposure is linked with both mild and severe psychiatric problems. This study emphasizes the importance of efforts to reduce smoking during pregnancy.

Individual dietary counselling during and after pregnancy: Impact on diet and body weight

In Finland, maternity and child health clinics play a key role in promoting health in young families. Currently, obesity causes the greatest challenges to clinics. In obese pregnant women, an increased risk for metabolic diseases exist which can affect both the mother and child. The purpose of this thesis was to explore the role of dietary counselling: in Finnish health clinics; in the regulation of dietary intake; and in affecting the body weight of women. The main aim was to test the effect of dietary counselling and probiotic intervention on dietary intake and maternal body weight during and after pregnancy. In addition to dietary counselling, the effect of other factors, such as eating behaviour on dietary intake and body weight control after pregnancy was assessed. Another aim was also to evaluate dietary counselling practices by nurses (n = 327) in Finnish health clinics assessed by a questionnaire. At the beginning of the pregnancy, women (n = 256) enrolled in a dietary intervention study, were randomised into three groups. One group received dietary counselling with probiotics, one had counselling with placebo and the third group was the control group. The control group consisted of women whom did not receive counselling and took placebo. Probiotics and placebo supplements were used until the end of exclusive breastfeeding or six months after pregnancy. Women were followed from early pregnancy up to four years after pregnancy. Follow-up visits took place three times during pregnancy, at one and six months, and one, two and four years after pregnancy. Dietary counselling, provided by a nutritionist, aimed to influence the quality of dietary fat intake. Dietary counselling is important to provide in clinics, as determined by the nurses, and these nurses expressed a want to improve their own nutritional knowledge through education. The nurses had varying knowledge of current dietary recommendations. Dietary counselling for women during and after pregnancy resulted in beneficial changes in dietary intake up to one year after pregnancy and body weight and waist circumference up to four years after pregnancy. Probiotics had a beneficial effect together with dietary counselling on waist circumference until one year after pregnancy, but not throughout the long term, four years after pregnancy. Other factors, such as eating behaviour, associated with dietary intake and body weight control after pregnancy. Specifically, dietary recommendations are reached amongst women whom had high cognitive restraint in their eating behaviour and did not demonstrate uncontrolled eating. Overweight women more frequently emotionally ate compared to normal weight women and women with central adiposity related more frequently to having an uncontrolled eating behaviour than women with normal waist circumference. In addition, being overweight prior to pregnancy and excessive weight gain during pregnancy associated with increased body weight retention after pregnancy. This study showed that individual dietary counselling is useful in influencing dietary intake which adheres to dietary recommendations and this counselling influences, favourably, body weight after pregnancy. Especially, women with the risk for weight retention, such as women who have emotional and uncontrolled eating behaviours, who were overweight prior to pregnancy or those who had excessive weight gain during pregnancy, may benefit from individual dietary counselling. This study underscores the need to develop dietary counselling practices for pregnant women and their follow-up after pregnancy in Finnish health clinics. These practices include increasing the efficacy of the counselling such as collaboration with families, having knowledgable health professionals and having sufficient resources.

Multiple sclerosis and pregnancy: clinical and immunological aspects

Background: Multiple Sclerosis (MS) is an autoimmune disease of the central nervous system that affects most commonly young women in their childbearing age. Previous studies have shown that MS relapse rate usually reduces during pregnancy and increases again after delivery. Patients with MS and their treating physicians are interested to know more about the risks the disease can cause to pregnancy and how pregnancy affects the disease. The reasons for increased relapse rate after delivery are not entirely clear, but loss of pregnancy related immune tolerance and changes in the hormonal status at the time of delivery seem to be of relevance. Aims and methods: The aims of this study were to follow the natural course of MS during and after pregnancy, evaluate pregnancy related risks among MS patients, follow the inflammatory response of MS patients during and after pregnancy and clarify the risk of relevant co-morbidities known to affect other autoimmune diseases after pregnancy and compare these results to healthy controls. This study was a part of a prospective nation-wide follow-up study of 60 Finnish MS patients. All eligible MS patients were enrolled in the study during the years 2003-2005. A prospective followup continued from early pregnancy until six months postpartum. MS relapses, EDSS scores and obstetric details were recorded. Blood samples were obtained from the patients at early, middle, and late pregnancy, after delivery and one month, three months and six months postpartum. Results: MS patients were no more likely to experience pregnancy or delivery complications than the Finnish mothers in general. The need of instrumental assistance, however, was higher among mothers with MS. Disease activity followed the course seen in previous studies. The majority of mothers (90.2%) breastfed their babies. Contrary to previous results, breastfeeding did not protect MS patients from disease worsening after delivery in present study. Mothers with active pre-pregnancy disease chose to breastfeed less frequently and started medication instead. MS patients presented with higher prevalence of elevated thyroid autoantibodies postpartum than healthy controls, but the rate of thyroid hormonal dysfunction was similar as that of healthy controls. The mode of delivery nor the higher rate of tissue damage assessed with C-reactive protein concentration were not predictive of postpartum relapses. The prevalence of gestational diabetes was slightly higher among mothers with MS compared to Finnish mothers in general, but postpartum depression was observed in similar rates. MS patients presented with significantly lower serum concentrations of vitamin D during pregnancy and postpartum than healthy controls. Conclusions: Childbearing can be regarded as safe for mothers with MS as it is for healthy mothers in general. Breastfeeding can be recommended, but it should be done only after careful evaluation of the individual risk for postpartum disease activation. Considering MS patients tend to develop thyroid antibody positivity after delivery more often than healthy controls and that certain treatments can predispose MS patients to thyroid hormonal dysfunction, we recommend MS mothers to be screened for thyroid abnormalities during pregnancy and after delivery. Increased risk for gestational diabetes should be kept in mind when following MS mothers and glucose tolerance test in early pregnancy should be considered. Adequate vitamin D supplementation is essential for MS mothers also during pregnancy and postpartum period.

Biomarkers, medical treatment and fetal intrapartum surveillance in intrahepatic cholestasis of pregnancy

Intrahepatic cholestasis of pregnancy (ICP) is a pregnancy-specific disorder characterized by maternal pruritus and elevated liver enzymes. It usually begins in the third trimester of pregnancy and resolves spontaneously after delivery. ICP is considered benign for the pregnant woman, but it is associated with an increased risk for unexplained term stillbirth and preterm delivery. There are no specific laboratory markers to diagnose ICP. The diagnosis is currently based on the presence of maternal pruritus and elevated values of alanine aminotransaminases (ALT) and serum bile acids (BA). Recently, ursodeoxycholic acid (UDCA) has been used for treatment. Mechanisms leading to intrauterine fetal death (IUFD) may be multifactorial and are unknown at present. For this thesis, 415 pregnant women with ICP were studied. The aim was to evaluate the value of the liver enzyme glutathione S-transferase alpha (GSTA) as a specific marker of ICP and to assess the effect of maternal UDCA therapy on maternal laboratory values and fetal outcome. The specific markers predisposing the fetus to heart arrhythmia were studied by comparing waveform analysis of fetal electrocardiograms (FECG) during labor in pregnancies complicated by ICP with controls. The levels of maternal GSTA were high and the values correlated with the value of ALT in patients with ICP. UDCA therapy reduced the values of the liver enzymes and alleviated maternal pruritus, but it did not influence maternal hormonal values. Although the newborns experienced an uneventful perinatal outcome, severe ICP was still associated with preterm birth and admission to the neonatal intensive care unit (NICU). There were no significant differences in intrapartum FECG findings between fetuses born to ICP women and controls.
