Safety of and response to electroconvulsive therapy during pregnancy: Results from population-based nationwide registries.

INTRODUCTION: Psychiatric disorders are common during pregnancy, affecting up to 16% of pregnant women. Severe depression and anxiety have significant negative effects on the health of both the mother and the developing fetus. Electroconvulsive therapy (ECT) is considered a treatment option for pregnant women with severe psychiatric disorders when other treatments have been ineffective or pose risks to the fetus. Knowledge of the safety and efficacy of ECT during pregnancy, however, remains limited. METHODS: Data were obtained from nationwide registries of pregnant women in Sweden who received ECT for a severe psychiatric disorder from January 2008 to December 2021. ECT-related outcomes in pregnant women were compared by propensity score matching with a group of non-pregnant women who also received ECT. Pregnancy-related outcomes were compared with two additional control groups: one consisting of the same group of women who did not receive ECT during another pregnancy and the other composed of pregnant women admitted to inpatient psychiatric care but who did not receive ECT, matched based on propensity score. RESULTS: Ninety-five pregnant women received ECT during the study period, accounting for 97 pregnancies. The response rate to ECT in pregnant women (n = 54) was similar to the matched control group of non-pregnant women (74% vs. 65%; OR 1.61; 95% CI 0.79-3.27). Rates of adverse events related to ECT were similar to those in the control group. There were no pre-term births or severe adverse outcomes related to the pregnancy, that were close in time to ECT. Therefore, no adverse outcomes related to pregnancy and childbirth could be directly attributed to ECT. The likelihood of premature birth and a 5-min Apgar score <7 in the newborn were both significantly higher in the ECT group, compared with the matched non-ECT group (OR 2.33, 95% CI 1.15-4.73, p = 0.008, and OR 3.68, 95% CI 1.58-8.55, p < 0.001, respectively). By contrast, no significant differences were observed when women in the pregnant ECT group were compared with the same group lacking ECT during another pregnancy. CONCLUSIONS: ECT was associated with a positive treatment response in pregnant women with severe psychiatric disorders. The response rate to ECT was similar in pregnant and non-pregnant women. Nevertheless, the risks of premature birth and of a slightly poorer condition in newborns were higher in women who did than did not receive ECT, emphasizing the need for increased attention to severe psychiatric disorders during pregnancy.

The evolution of epilepsy surgery in tuberous sclerosis in Sweden: A national registry study.

PURPOSE: This study aimed to characterize the Swedish cohort of surgically treated patients with TSC and explore differences in preoperative investigation and outcome over time. METHODS: Data on patient and seizure characteristics were retrieved from the Swedish National Epilepsy Surgery Register. Two-year follow-up results were compared between the years 1997-2010 and 2011-2018. Preoperative investigations were re-evaluated. RESULTS: Eighteen tuberectomies and seven callosotomies were identified. Seizure freedom after tuberectomy was achieved in 11 % (1/9) 1997-2010 and 56 % (5/9) 2011-2018. The number of tuberectomies increased each decade. Patients operated on in 1997-2010 had higher seizure frequency (median 175 seizures/month vs. 102) and incidence of infantile spasms (4/9 vs. 1/9, none after 2011). There was a trend towards surgery at a younger age (median 86 months 1997-2010 vs. 48 months 2011-2018). None with >200 seizure/month, SEGA, or history of infantile spasms achieved seizure freedom. Two patients underwent anterior callosotomy (1992 and 1994) and became free of drop attacks. Five callosotomies were performed between 2011 and 2013, one patient became free of drop attacks. Two complications with new neurological deficits were reported. The median age at surgery was higher in the callosotomy group (14 years) than in the tuberectomy group (5 years). CONCLUSION: Seizure freedom after tuberectomy in patients with TSC has increased over time in our cohort. Signs of a heavier disease burden were more frequently observed 1997-2010 and associated with worse outcomes. Callosotomy operations were prevalent at the beginning of the 2010s.

Introducing brief admissions by self-referral in child and adolescent psychiatry: an observational cohort study in Sweden.

BACKGROUND: Brief admission by self-referral, a novel crisis intervention designed to reduce suicide and self-harm in adults, was adopted for adolescents in paediatric psychiatry in Malmö, Sweden, in 2018. We aimed to investigate changes in utilisation of emergency psychiatric care. METHODS: We did an observational longitudinal cohort study in The University Hospital in Malmö, Sweden, which provides the only psychiatric emergency unit with 24 h psychiatric facilities in Region Skåne. Eligible patients were those aged 13-17 years who were admitted to the psychiatric facility, who had at least one emergency visit or admission during the 6 months before admission, and had prominent features of instability and self-harm, corresponding to at least three of the nine criteria for borderline personality disorder as per the DSM-5 as assessed by a paediatric psychiatrist during the admission. Patients with intellectual disabilities, psychosis, or language barriers were excluded. Patients who signed a brief admissions contract between April 1, 2018, and April 30, 2021, were eligible for inclusion in the study. A brief admissions contract allows patients to admit themselves to psychiatric emergency care for a transitory time. The primary outcome measures were the number of emergency visits, emergency admissions, inpatient days, and episodes of coercive (involuntary) care, compared at individual level before and after signing the brief admissions contract until end of follow-up. The number of visits and days were modelled using random-effects Poisson regression models, and the relative changes in the expected numbers of days per time unit were reported as rate ratios (RRs). FINDINGS: Of the 928 patients admitted to the psychiatric facility between April 1, 2018, and April 30, 2021, 60 were excluded, and a further 801 did not meet the inclusion criteria for age, previous emergency visits, or having at least three of the nine criteria of borderline personality disorder. 67 patients were eligible for inclusion, but four patients did not sign a contract. 63 patients were included in the study, including 60 females (95%) and three (5%) males, with a mean age of 14·8 years (SD 1·7). Ethnicity data were not collected. Patients were followed up for a median of 13·5 months (IQR 9·2 -19·6). After signing the contract, there was a decrease in the number of emergency visits (RR 0·22 [95% CI 0·15-0·32]; p<0·0001), emergency admissions (RR 0·26 [0·19-0·35]; p<0·0001), inpatient days (RR 0·29 [0·26-0·32]; p<0·0001), and inpatient days including brief admissions (RR 0·44 [95% CI 0·40-0·48]; p<0·0001). Episodes of coercive care did not change significantly (RR 0·99 [95% CI 0·40-2·43]; p=0·98). Psychiatric evaluation due to persistent suicidal ideations immediately after discharge was required for five patients. INTERPRETATION: Our findings suggest that brief admissions can be successfully implemented in paediatric psychiatry and appear to be an effective crisis management method for adolescents, associated with reduced demand for emergency care. Future randomised controlled trials are warranted. FUNDING: Region Skåne Health Care Authority.

Adolescent and Family-Focused Cognitive-Behavioral Therapy for Pediatric Bipolar Disorders: An Open Trial and Individual Trajectories Study in Routine Psychiatric Care.

Psychosocial treatments improve outcome in Pediatric bipolar disorder (PBD), but few are developed specifically for adolescents and none has been evaluated in Europe. This study evaluates family-focused cognitive-behavioral therapy for adolescents (ages 13-18) with PBD in routine psychiatric care in Sweden, adapted for teenagers in a European setting from the Child and Family-Focused Cognitive Behavioral Therapy for PBD (ages 8-12) developed in the US. In a repeated-measure open trial, psychosocial functioning, depression, skills and knowledge about PBD, and family climate were assessed at pre-treatment, post-treatment, and after 6 months. Assessments were made by adolescents (n = 45), parents (n = 61) and clinicians. Both group statistics and individual trajectories are reported. Psychosocial function, as rated by parents and clinicians, improved at post-treatment, and parents reported less mania and improved family climate at post-treatment. Both parents and adolescents reported improved skills and knowledge. Most results after treatment showed medium effect sizes. Significant improvements were seen in most individual trajectories, however no change and even deterioration was observed in some. The present trial shows that AFF-CBT is well accepted and associated with improved psychosocial function in adolescents and improved skills and knowledge about PBD in adolescents and their parents. Regarding mood symptoms and family climate the results showed more individual variability, indicating that adjustments in delivery of the treatment according to the unique patient could be of importance. AFF-CBT seems to be a valuable addition to pharmacological treatments in PBD.

Electroconvulsive therapy in children and adolescents: results from a population­based study utilising the Swedish National Quality Register.

Electroconvulsive therapy (ECT) is effective and safe for adults with severe depression, but less studied in adolescents. Here, we examined the indications, prevalence, practice, response and remission rates, and side effects in young people treated with ECT in Sweden. We also examined the usage of ECT in the transition to adult psychiatry. Using data from national patient registers and the Swedish National Quality Register for ECT (Q-ECT), we identified patients aged up to 19 years treated with ECT over a 5-year study period. Response and remission rates were analysed using the Clinical Global Impression (7-point scale)-Improvement (CGI-I) and Severity (CGI-S). A total of 118 individuals were identified, of which 105 were also enrolled in the Q-ECT. The most common indication for ECT was depression (68%; n = 80). Adolescents aged < 18 years were more severely ill before treatment than those aged 18 years (P < 0.01). Three of the hospitals in Sweden treated the majority of adolescents < 18 years old. The median number of sessions in each ECT series was seven. Unilateral placement of the electrodes was the most common (88%; n = 99). Fifty-seven percent (n = 54) of the patients responded (CGI-I, 1-2) to the treatment; remission (CGI-S, 1-2) was achieved by 32% (n = 30). Psychotic symptoms were associated with a higher response rate in patients with depression (P = 0.038). A deterioration of memory compared to pre-treatment was reported in six patients. ECT was associated with high response and remission rates in adolescents with severe psychiatric disorders after non-response to medication.

Implementation of Brief Admission by Self-Referral in Child and Adolescent Psychiatry in Sweden: Insights from Implementers and Staff.

Brief admission by self-referral, which allows patients to briefly admit themselves to a psychiatric ward, is a crisis intervention designed to reduce suicide and self-harm. This method was introduced in Sweden for adult patients in 2015, achieving high patient satisfaction and good acceptance among staff. In 2018, the method was adapted and implemented in pediatric psychiatry. The present study comprehensively describes the multifaceted strategies for implementing brief admissions, including planning, education, financing, restructuring, quality management, and policy implementation and reform. It also includes staff's opinions of the practice of brief admissions for young people. Neither of these topics has been addressed in the existing literature. During the study period (April 2018-April 2021), 63 brief admission contracts were established. The number of new contracts increased exponentially (12.7%) per quarter (p < 0.05), and staff satisfaction with both the implementation and its benefits for unstable patients was high. Brief admission by self-referral can be successfully implemented in pediatric psychiatry and appears to be a functional crisis management method for adolescents.

Satisfaction and seizure outcomes of epilepsy surgery in tuberous sclerosis: A Swedish population-based long-term follow-up study.

PURPOSE: We conducted a cross-sectional study to evaluate long-term outcomes of epilepsy surgery in tuberous sclerosis complex (TSC) in a Swedish population. METHODS: Demographic and seizure data was retrieved from the Swedish National Epilepsy Surgery Registry and medical records. Patient reported outcome measurements (PROM) were determined by telephonic interviews at long term follow-up. RESULTS: Median follow-up was 6 y 8 m (range, 3-15 y 1 m) for tuberectomies (n = 15) and 3 y 6 m (range 2-10 y) for callosotomies (n = 7). Eight of the 15 tuberectomy participants were seizure-free. Four out of seven callosotomies were free from drop attacks. PROMs were provided by caregivers of 18/20 participants (data missing for two callosotomies). In the tuberectomy group, 6/8 patients were seizure-free and 3/7 had continued seizures; surgery was considered satisfactory and beneficial. Overall, satisfaction was high, even among patients who did not achieve remission; 13/15 tuberectomy responders recommended surgery to others with TSC and refractory epilepsy. None of the patients considered the surgery harmful. In the callosotomy group, satisfaction was low and congruent with the seizure outcome. All patients with continued drop attacks were unsatisfied; one considered surgery to be harmful. One participant, who would not recommend surgery to others, still perceived the surgery to be beneficial. CONCLUSIONS: This study confirmed that both tuberectomy and callosotomy are effective treatment options for TSC. Factors other than seizure outcomes seemed to have a major influence on satisfaction and perception of the benefit of surgery.

Moderate-to-vigorous group aerobic exercise versus group leisure activities for mild-to-moderate depression in adolescents: study protocol for a multicentre randomised controlled trial.

INTRODUCTION: Depression is common, increasing among adolescents and carries risk of disability, lower educational achievements, cardiovascular disease, substance abuse, self-harm and suicide. The effects of evidence-based treatments with medication or psychotherapy are modest. Aerobic exercise is a promising intervention for adolescents with depression, but available studies are hampered by methodological shortcomings. This study aims to evaluate aerobic group exercise versus an active comparator of leisure group activities in adolescents from clinical services with mild-to-moderate depression. METHODS AND ANALYSIS: This study is a multicentre randomised controlled trial at four psychiatric clinics in Sweden. Participants (n=122) will be randomised 1:1 to group exercise delivered by exercise professionals and supported by mental health (MH) workers or leisure activities lead by the same MH workers for 1 hour three times a week for 12 weeks. Participants will be assessed at baseline, single blind after 13 weeks and 26 weeks and openly after 1 year. Participants randomised to the leisure group will be offered exercise in the open phase. The primary outcome is clinician-rated Children's Depression Rating Scale-Revised. Secondary outcomes are self-rated Quick Inventory of Depressive Symptomatology, self-rated functioning; clinician-rated improvement and functioning; objectively measured aerobic capacity, muscular strength, muscular endurance, body composition and presence or activity of selected biological markers of neuroprotection and neuroinflammation in blood samples. Further outcomes are cost-effectiveness and adolescents', parents' and coaches' experiences of the interventions and an exploration of how the adolescents' health and lifestyle are influenced by the interventions through qualitative interviews. ETHICS AND DISSEMINATION: The study is approved by the Swedish Ethical Review Authority (Ref. 2021-05307-01). Informed consent in writing will be provided from patients and parents of participants below 15 years of age. The results of this study will be communicated to the included participants and healthcare providers and also submitted for publication in peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT05076214.

Prospective registration of symptoms and times to diagnosis in children and adolescents with central nervous system tumors: A study of the Swedish Childhood Cancer Registry.

BACKGROUND: The elapsed time taken to diagnose tumors of the central nervous system in children and adolescents varies widely. The aim of the present study was to investigate such diagnostic time intervals at a national level in Sweden as they correlate with clinical features. METHODS: Data prospectively accumulated over a 4-year period in the Swedish Childhood Cancer Registry from patients aged 0-18 years were pooled, and diagnostic time intervals were analyzed considering tumor location, tumor type, patient age and sex, initial symptoms, and clinical timelines. All six pediatric oncology centers in Sweden contributed to collection of data. Time points for calculating the total diagnostic interval (TDI) defined as the time from symptom onset to diagnosis were reported in 257 of 319 patients (81%). RESULTS: The time from symptom onset to the first healthcare consultation, median 2.6 weeks, did not vary significantly between patients categorized according to tumor type or location. The median TDI was 8.3 weeks for the 4-year study period. Patients with optic pathway glioma (TDI 26.6 weeks), those with tumors of the spinal cord (TDI 25.9 weeks), and those with midline tumors (TDI 24.6 weeks) had the longest lead times. Additionally, older age, too few initial symptoms, and seeking initial redress outside an emergency ward were factors associated with a longer time to diagnosis. CONCLUSION: This study identified several factors associated with delayed diagnosis of central nervous system tumors among Swedish children and adolescents. These novel data ought to help direct future efforts toward clinical improvement.

The Winding Road to Equal Care: Attitudes and Experiences of Prescribing ADHD Medication among Pediatric Psychiatrists: A Qualitative Study.

Evidence is lacking on how to understand the reasons for variations, both in prevalence of ADHD and ADHD medication prescribing patterns in children and adolescents, within Region Skåne. These variations are not in line with current national clinical guidelines and seem to have increased over time. This qualitative interview study illuminates pediatric psychiatrists' attitudes toward ADHD and their experiences of prescribing ADHD medication. Eleven pediatric psychiatrists described the complex interplay of variables that they experienced while assessing a child, which had influence on their decision to prescribe medication. Being part of a local unit's culture influenced how ADHD medications were prescribed. They wished that the assessment of the child's symptoms was consistent with guidelines in every unit but noted that such alignment was not implemented. They pointed out that an ADHD diagnosis is dependent on the surrounding's motivation and capacity to adapt to the present state of the child. The participants described how they balanced clinical guidelines with demands from the family, as well as from society at large. Their personal attitudes and clinical experiences towards diagnosing and prescribing medications to children with ADHD influenced their decisions. The study adds information about how attitudes may lead to variation in diagnostics and therapy.

Methods and Strategies for Reducing Seclusion and Restraint in Child and Adolescent Psychiatric Inpatient Care.

Restraints and seclusions are restrictive interventions used in psychiatric inpatient units when there is an imminent risk of harm to the patient or others. Coercive measures are controversial and can lead to negative consequences, including negative emotions, re-traumatization, injuries, or death. The article summarizes the last 10 years of literature regarding methods and strategies used for reducing seclusions and restraints in child and adolescent psychiatric inpatient units, and reports on their outcomes. The literature was reviewed by searching PubMed and PsycInfo for English-language articles published between May 2010 and May 2020. Eighteen articles were found that described methods or strategies aimed at reducing restraint or seclusion utilization in child and adolescent psychiatric inpatient units. The following interventions were evaluated: Trauma-Informed Care (TIC), Six Core Strategies, Child and Family Centered Care (CFCC), Collaborative & Proactive Solutions (CPS), Strength-Based Care, Modified Positive Behavioral Interventions and Supports (M-PBIS), Behavioral Modification Program (BMP), Autism Spectrum Disorder Care Pathway (ASD-CP), Dialectical Behavior Therapy (DBT), sensory rooms, Mindfulness-Based Stress Reduction Training (MBSR) of staff, and Milieu Nurse-Client Shift Assignments. Most of the interventions reduced the use of seclusions and/or restraints. Two child-centered and trauma-informed initiatives eliminated the use of mechanical restraints. This review shows that the use of coercive measures can be reduced and should be prioritized. Successful implementation requires ongoing commitment on all levels of an organization and a willingness to learn. To facilitate comparisons, future models should evaluate different standardized parameters.

Acute Mania and Catatonia in a Teenager Successfully Treated with Electroconvulsive Therapy and Diagnosed with Turner Syndrome and Bipolar Disorder.

BACKGROUND: Turner syndrome (TS) is an X-linked chromosomal abnormality with a global prevalence of 1/2000 live-born girls. The physiological symptoms of TS have been thoroughly characterized, but only a few studies have described associated psychiatric symptoms. We report a case of an adolescent girl who presented with acute mania with psychotic features and was successfully treated with electroconvulsive therapy (ECT). She was subsequently diagnosed with bipolar syndrome and TS. Case Presentation. A 17-year-old girl presented to us with manic symptoms, including disorganized speech, auditory hallucinations, and affect lability. Initially, she was treated with antipsychotics and benzodiazepines, whereby the positive affective symptoms declined. However, the psychotic symptoms progressed, and she developed a catatonic state. ECT was started 6 days after admission, with improvement after two treatments. When ECT was tapered after seven sessions, she relapsed, and the treatment was extended to twelve sessions, with successful outcome. Following discharge, she was diagnosed with TS with partial loss on one of the X-chromosomes (46X, del (X)(p21)), which might have contributed to the development of her sudden acute manic episode. CONCLUSIONS: This case demonstrates for the first time that ECT may be a safe and efficient treatment strategy for acute mania in adolescents with concomitant TS and that severely affected adolescents may require a prolonged series with gradual tapering of ECT. The present case also demonstrates a possible association between TS and bipolar syndrome and that the clinical presentation of a manic episode in a patient with this comorbidity could be more complex and the treatment response slower.

Risky Alcohol Use and Comorbidity in a Swedish Adolescent Emergency Psychiatric Inpatient Population.

INTRODUCTION: Underage drinking is associated with poor mental health. Early detection for risky alcohol use is recommended, although less implemented in adolescent care. The objective of this study was to investigate the prevalence of risky alcohol use and psychiatric comorbidity. METHODS: Over a nine-month period, 145 eligible adolescents admitted to the child and adolescent emergency unit in Malmö, Sweden, were offered computerized screening with Alcohol Use Disorder Identification Test-Consumption (AUDIT-C) and Drug Use Disorders Identification Test (DUDIT). RESULTS: Ninety-six patients (73 girls and 23 boys) agreed to participate. The most common diagnoses were affective disorder (41%) and anxiety disorder (27%). Risky alcohol use was found among 33% of the girls and 22% of the boys (p=0.45) and did not differ between diagnostic categories. There was a positive correlation between AUDIT-C and DUDIT scores (p=0.019). Among adolescents with risky alcohol use, 33% of the girls and 60% of the boys also had a risky drug use. Conversely, 47% of the girls and 60% of the boys with risky drug use also had a risky alcohol use. CONCLUSION: In view of the poor prognosis of risky alcohol use in adolescents, alcohol and drug habits should be assessed when adolescents seek psychiatric emergency care.

Acute manic state with psychotic features in a teenager with autoimmune encephalitis: a case report.

INTRODUCTION: Autoimmune disorders have become increasingly acknowledged as having a more causative role in encephalitis than previously assumed. Anti-N-methyl-D-aspartate receptor encephalitis seems to be the most prevalent disorder. Symptoms of the neuropsychiatric phase in children and adolescents include abnormal behavior, seizures, and neurologic symptoms. We present a report on a teenage girl with predominantly psychiatric symptoms, highlighting the need for awareness of the disease and multidisciplinary collaboration. CASE PRESENTATION: Our patient, a 17-year-old girl of Middle Eastern origin, had no earlier medical history, but a family history of autoimmune disease. One morning, she could not recognize her mother and soon developed increased energy and pressured speech. The condition worsened, with paranoid delusions. In the emergency unit, she ran around speaking incoherently. The condition was interpreted as a full-scale mania. After pediatric clearance, the patient was admitted to the Department of Child and Adolescent Psychiatry. Mood-stabilizing treatment was initiated with second-generation psychotics and lithium, but this brought no improvement. A multidisciplinary discussion was held with physicians from psychiatry and neurology. A lumbar puncture showed N-methyl-D-aspartate receptor antibodies, and autoimmune treatment was initiated. Computed tomography thorax/abdomen revealed a right-sided ovarian tumor. After salpingo-oophorectomy, our patient's mental status gradually improved, as demonstrated by repeated testing. Seven months post discharge she was in a stable relationship and performing well in school. CONCLUSION: This case underlines the importance of collaboration between child and adolescent psychiatry and pediatrics, and gives pointers for timely diagnosis. Manic adolescents who do not respond to mood-stabilizing treatment should be subjected to further consultations and investigations. Psychiatrists and neurologists should develop an integrated approach to the management of brain disorders.

'A Safe Place Where I Am Welcome to Unwind When I Choose to'-Experiences of Brief Admission by Self-Referral for Adolescents Who Self-Harm at Risk for Suicide: A Qualitative Study.

Evidence is lacking on how to manage imminent suicidality in adolescents with self-harm. Brief Admission by Self-referral (BA) is a crisis-management intervention, developed for adults with self-harm at risk for suicide. Structured, individualized and based on responsible autonomy, BA aims to provide a respite while minimizing negative effects of hospitalization. This qualitative interview study illuminates adolescents' experiences of BA, adapted for this target group. Nineteen adolescents aged 14 to 19 years, described BA as helpful for timely rest and recovery to save themselves from impulses to self-harm. The individual contract, which is a prerequisite for access to BA, was perceived to give access to professional support in a safe environment, also among adolescents not using their contract. Being trusted with responsibility to self-admit was also hard work with struggles of self-doubt. Challenges included experiencing distrust from staff and fear of not being able to abstain from self-harm, which BA is conditioned upon. However, this condition was also perceived to induce self-motivation and growth. BA appeared well-adapted to the target group, fulfilling needs of predictability, autonomy, and opportunity for recovery to prevent self-harm. Suggestions for improvement included continually informing staff about important features of BA. To further evaluate benefits and challenges of BA, future research may evaluate clinical and health-economic outcomes and perspectives from parents and caregivers.

[Pharmacotherapy of epilepsy]. / Läkemedelsbehandling av epilepsi: - Många nya alternativ men måttliga framsteg.

Pharmacotherapy of epilepsy is usually initiated after two or more unprovoked seizures, a decision that should be made after assessment of the individual risk of further seizures. Antiepileptic drugs (AEDs) are selected based on documented efficacy for the type of seizures, the epilepsy and possible epilepsy syndrome of the patient, taking potential adverse effects and comorbidity into account. For many AEDs, the mechanisms of action are incompletely understood. More than half of patients with newly diagnosed epilepsy achieve sustained seizure freedom with their first or second drug trials. After a prolonged time of seizure freedom discontinuation of therapy may be considered; the risk of relapse after drug withdrawal can be estimated on the basis of a number of clinical factors. The informed patient's attitude is essential in all therapy decisions. Treatment is still largely symptomatic, but the future may involve a greater degree of disease-modifying precision medicine.

Electroconvulsive therapy for manic state with mixed and psychotic features in a teenager with bipolar disorder and comorbid episodic obsessive-compulsive disorder: a case report.

BACKGROUND: Comorbidity of bipolar disorder and obsessive-compulsive disorder is common in adolescence. Obsessive-compulsive disorder symptoms may be episodic and secondary to alterations in mood, and display specific features. Management of pediatric bipolar disorder-obsessive-compulsive disorder is challenging, as pharmacotherapy of obsessive-compulsive disorder may induce or exacerbate manic episodes and there is limited evidence of treatment efficacy. Electroconvulsive therapy is sparsely used in children and adolescents, but is documented to be a safe and efficacious intervention in adults with bipolar disorder. In view of the severity of symptoms in juvenile mania, studies on treatment strategies are warranted. We report a case of an adolescent with bipolar disorder-obsessive-compulsive disorder who was successfully treated with electroconvulsive therapy during an episode of severe mania. CASE PRESENTATION: A 16-year-old girl of Middle East origin first presented to us with depressed mood, irritability, and increased obsessive-compulsive disorder symptoms, which were initially interpreted in the context of acute stress secondary to migration. She had been diagnosed with bipolar disorder and obsessive-compulsive disorder in her previous home country, but had difficulties in accounting for earlier psychiatric history. During hospitalization her mood switched to a manic state with mixed and psychotic features, at times showing aggression toward others. Interruption in her lithium treatment for a short period and possibly the introduction of an atypical antipsychotic could in part have been triggering factors. After 8 weeks of in-patient care and psychotropic drug trials, electroconvulsive therapy was initiated and administered every second or third day for 4 weeks, with marked positive response. No apparent side effects were reported. CONCLUSIONS: This case demonstrates the need for a detailed medical history, taking special note of periodicity and character of obsessive-compulsive disorder symptoms, in adolescents with mood disorders. When treating culturally diverse patients, extra consideration should be taken. Special concerns in the pharmacological treatment to avoid the patient's condition from worsening must be addressed, including giving priority to mood stabilization before obsessive-compulsive disorder symptoms. There are potential benefits in considering electroconvulsive therapy in young patients with severe mania where first-line treatment options have failed.

Epilepsy in tuberous sclerosis patients in Sweden - Healthcare utilization, treatment, morbidity, and mortality using national register data.

PURPOSE: This study is designed to estimate the prevalence of epilepsy associated with TSC in Sweden and to describe treatment, morbidity, and mortality of TSC patients with epilepsy. METHODS: Register data for 2004-2014 was obtained from the National Board of Health and Welfare in Sweden. Patients with TSC were identified using ICD-10 codes. Epilepsy was identified using ICD-10 codes, interventions aimed to treat epilepsy, or prescriptions for antiepileptic drugs. RESULTS: The prevalence of TSC was 5.38 per 100 000 individuals. We identified 551 unique patients with TSC, of which 386 (70.1%) had epilepsy. The mean study period was 8.82 years. Antiepileptic drugs were dispensed to 97.9% of patients with epilepsy. The most prescribed antiepileptic drug was sodium valproate. Ketogenic diet was used in 6 (1.6%) patients, vagus nerve stimulation in 23 (6.0%) patients, and epilepsy surgery was performed in 25 (6.5%) patients. The mean number of outpatient visits per year was 4.70 (SD 4.17) and the mean number of inpatient days per year was 3.25 (SD 5.61). The mean number of outpatient visits per year with an ICD-10 code for epilepsy was 1.65 (SD 1.95) and the corresponding number of inpatient days was 2.06 (SD 4.50). A total of 30 patients with TSC and epilepsy died during the study period. CONCLUSIONS: The prevalence of epilepsy in this study was in the lower range of previously reported numbers, suggesting that epilepsy may be overestimated in non-population based studies. A substantial part of the healthcare utilization was directly related to epilepsy.

Cerebellar mutism syndrome in children with brain tumours of the posterior fossa.

BACKGROUND: Central nervous system tumours constitute 25% of all childhood cancers; more than half are located in the posterior fossa and surgery is usually part of therapy. One of the most disabling late effects of posterior fossa tumour surgery is the cerebellar mutism syndrome (CMS) which has been reported in up to 39% of the patients but the exact incidence is uncertain since milder cases may be unrecognized. Recovery is usually incomplete. Reported risk factors are tumour type, midline location and brainstem involvement, but the exact aetiology, surgical and other risk factors, the clinical course and strategies for prevention and treatment are yet to be determined. METHODS: This observational, prospective, multicentre study will include 500 children with posterior fossa tumours. It opened late 2014 with participation from 20 Nordic and Baltic centres. From 2016, five British centres and four Dutch centres will join with a total annual accrual of 130 patients. Three other major European centres are invited to join from 2016/17. Follow-up will run for 12 months after inclusion of the last patient. All patients are treated according to local practice. Clinical data are collected through standardized online registration at pre-determined time points pre- and postoperatively. Neurological status and speech functions are examined pre-operatively and postoperatively at 1-4 weeks, 2 and 12 months. Pre- and postoperative speech samples are recorded and analysed. Imaging will be reviewed centrally. Pathology is classified according to the 2007 WHO system. Germline DNA will be collected from all patients for associations between CMS characteristics and host genome variants including pathway profiles. DISCUSSION: Through prospective and detailed collection of information on 1) differences in incidence and clinical course of CMS for different patient and tumour characteristics, 2) standardized surgical data and their association with CMS, 3) diversities and results of other therapeutic interventions, and 4) the role of host genome variants, we aim to achieve a better understanding of risk factors for and the clinical course of CMS - with the ultimate goal of defining strategies for prevention and treatment of this severely disabling condition.
