Perceptions of sexuality and sexual health among young people in the Netherlands

Sexual health problems are not uncommon among young people in the Netherlands and finding the proper treatment for such problems is often challenging. More insight regarding young people's perceptions of sexuality and its associated problems is needed to improve both treatment and education. This qualitative study of 22 young people (aged 13 to 25 years) explored perceptions of sexuality and sexual health. The results show that sexuality is narrowly defined by young people, with focus clearly being placed on physical aspects of sexuality, and sexual intercourse in particular. Sexual problems are usually defined as physical or medical problems. The data show that participants had limited knowledge regarding sexual problems associated with sexual functioning. Schools, parents and culture all appear to play a role in perceptions of sexuality and sexual health. In their totality, the findings suggest that knowledge about the complexity of sexuality and sexual health is lacking among young people in the Netherlands. We recommend broader sexual health education programs in schools that include the discussion of multiple aspects of sexuality, including pleasure. We also suggest that parents take a more prominent role in educating their children about sexuality.     

Olanzapine in the treatment of depression with psychotic features: A prospective open-label study

Objective. Depression with psychotic features is a severe subtype of major depression associated with the presence of delusions, hallucinations and specific neurobiological features. Despite clinical consensus and guideline recommendations, data comparing the efficacy of combining antipsychotics with antidepressants compared to antidepressants alone remain inconclusive. The aim of the study was to investigate effectiveness and tolerability of the atypical antipsychotic olanzapine in acute depression with psychotic features. Methods. Seventeen inpatients with major depressive disorder with psychosis (MDDp) were treated with a combination of an antidepressant and olanzapine for 6 weeks in a prospective open-label study. Depressive and psychotic symptoms, extrapyramidal and general side effects were assessed every 2 weeks. Sixteen patients were eligible for final analysis. Results. The Brief Psychiatric Rating Scale (BPRS) showed a 30% symptom reduction after week 2, a 45% symptom reduction after week 4 and no considerable improvement thereafter. Depressive symptoms (Bech–Rafaelsen Melancholia Scale, BRMS) receded by 37% after week 2 and 50% after week 4. No extrapyramidal side effects occurred. Conclusion. Olanzapine is effective and tolerable in combination with an antidepressant in an MDDp inpatient sample. The results concur with data supporting good efficacy in negative and depressive symptoms of patients with schizophrenic and schizoaffective diseases.     

Use of Trial 1 of the Test of Memory Malingering (TOMM) as a Screening Measure of Effort: Suggested Discontinuation Rules

Trial 1 of the Test of Memory Malingering (TOMM) has been suggested as a screening tool, with several possible cut-off scores proposed. The purpose of the present study was to replicate the utility of previously suggested cut-off scores and to characterize neuropsychological profiles of persons who “pass” the TOMM but obtain Trial 1 scores <45 and of persons with cognitive disorders. A total of 229 veterans were administered the TOMM as part of a neuropsychological evaluation. Trial 1 scores ≥41 and ≤25 showed good utility as discontinuation scores for adequate and poor effort, respectively, beyond which administration of additional trials were unnecessary. Findings suggest better Trial 1 performance is significantly related to better speeded mental flexibility and memory.     

Stimulus-induced rhythmic,periodic or ictal discharges (SIRPIDs) in comatose survivors of cardiac arrest: Characteristics and prognostic value

ObjectivesTo analyze the prevalence of stimulus-induced rhythmic, periodic or ictal discharges (SIRPIDs) in patients with coma after cardiac arrest (CA) and therapeutic hypothermia (TH) and to examine their potential association with outcome.MethodsWe studied our prospective cohort of adult survivors of CA treated with TH, assessing SIRPIDs occurrence and their association with 3-month outcome. Only univariated analyses were performed.Results105 patients with coma after CA who underwent electroencephalogram (EEG) during TH and normothermia (NT) were studied. Fifty-nine patients (56%) survived, and 48 (46%) had good neurological recovery. The prevalence of SIRPIDs was 13.3% (14/105 patients), of whom 6 occurred during TH (all died), and 8 in NT (3 survived, 1 with good neurological outcome); none had SIRPIDs at both time-points. SIRPIDs were associated with discontinuous or non-reactive EEG background and were a robustly related to poor neurological outcome (p < 0.001).ConclusionThis small series provides preliminary univariate evidence that in patients with coma after CA, SIRPIDs are associated with poor outcome, particularly when occurring during in therapeutic hypothermia. However, survival with good neurological recovery may be observed when SIRPIDs arise in the post-rewarming normothermic phase.SignificanceThis study provides clinicians with new information regarding the SIRPIDs prognostic role in patients with coma after cardiac arrest.     

Serial MRI findings in brain anoxia leading to Lance–Adams syndrome: a case report

Although in literature almost 150 patients with Lance-Adams Syndrome (LAS) have been reported, neuroradiological evaluations were often performed in late stages and there is no serial study evaluating LAS from early stages. We herein report a serial neuroimaging study demonstrating early and transient involvement of cerebellum and thalami in a LAS patient. We may hypothesize that a transient cerebral hypoxia provoked a permanent synaptic rearrangements of the neuronal networks involved in the pathogenesis of post-hypoxic myoclonus in our patient.     

Experimental Study of the Course of Threshold Current,Voltage and Electrode Impedance During Stepwise Stimulation From the Skin Surface to the Human Cortex

BackgroundTranscranial electric stimulation as used during intraoperative neurostimulation is dependent on electrode and skull impedances.ObjectiveThreshold currents, voltages and electrode impedances were evaluated with electrical stimulation at 8 successive layers between the skin and the cerebral cortex.Patients and MethodsData of 10 patients (6f, 53 ± 11 years) were analyzed. Motor evoked potentials were elicited by constant current stimulation with corkscrew type electrodes (CS) at C3 and C4 in line with standard transcranial electric stimulation. A monopolar anodal ball tip shaped probe was used for all other measurements being performed at the level of the skin, dura and cortex, as well as within the skull by stepwise performed burr holes close to C3 resp. C4.ResultsAverage stimulation intensity, corresponding voltage and impedance for muscle MEPs at current motor threshold (CMT) were recorded: CS 54 ± 23 mA (mean ± SD), 38 ± 21 V, 686 ± 146 Ω; with the monopolar probe on skin 55 ± 28 mA, 100 ± 44 V, 1911 ± 683 Ω and scalp 59 ± 32 mA, 56 ± 28 V, 1010 ± 402 Ω; within the skull bone: outer compact layer 33 ± 23 mA, 91 ± 53 V, 3734 ± 2793 Ω; spongiform layer 33 ± 23 mA, 70 ± 44 V, 2347 ± 1327 Ω; inner compact layer (ICL) 28 ± 19 mA, 48 ± 23 V, 2103 ± 1498 Ω; on dura 25 ± 12 mA, 17 ± 12 V, 643 ± 244 Ω and cortex 14 ± 6 mA, 11 ± 5 V, 859 ± 300 Ω. CMTs were only significantly different for CS (P = 0.02) and for the monopolar probe between the cortex and ICL (P = 0.03), scalp (P = 0.01) or skin (P = 0.01) and between ICL and CS (P ≤ 0.01) or skin (P ≤ 0.01).ConclusionThe mean stimulation current of the CMT along the extracranial to intracranial anodal trajectory followed a stepwise reduction. VMT was strongly dependent on electrode impedance. CMT within the skull layers was noted to have relative strong shunting currents in scalp layers.     

MRI Predicts Efficacy of Constraint-Induced Movement Therapy in Children With Brain Injury

Using resting state (RS) functional magnetic resonance imaging (fMRI) and diffusion tensor imaging (DTI), we identified the predictors of clinical improvement following constraint-induced movement therapy (CIMT) in pediatric patients with chronic hemiplegia.From 14 children with congenital or acquired brain injury and 10 sex- and age-matched healthy controls, brain dual-echo, DTI and RS fMRI sequences were acquired before CIMT. The Quality of Upper Extremities Skills Test and the Gross Motor Function Measure (GMFM) were administered at baseline, at the end of CIMT (10 weeks), and after 6 months. Mean diffusivity and fractional anisotropy (FA) were measured in the lesion responsible for the clinical symptomatology, the affected and unaffected corticospinal tract (CST), motor transcallosal fibers, and uncinate fasciculus (as an internal control). Independent component analysis was used to identify the sensorimotor RS network. The ability of baseline MRI variables to predict clinical changes over time was assessed using multivariate linear models. At baseline, patients had increased mean diffusivity in the symptomatic lesion and decreased FA in the symptomatic lesion, affected corticospinal tract, and motor transcallosal fibers. A reduced RS functional connectivity was found in the bilateral cerebellum, left precentral gyrus, and right secondary sensorimotor cortex. At follow up, Quality of Upper Extremities Skills Test and GMFM scales improved significantly. Baseline average lesion FA predicted clinical improvement at week 10, and baseline functional connectivity of the right secondary sensorimotor cortex and cerebellum predicted GMFM improvement at month 6. DTI and RS fMRI offer promising and objective markers to predict clinical outcomes following CIMT in pediatric patients with congenital or acquired hemiplegia.     

On occasionally being able to paint

Many of us find that our own work suffers when we practise as art therapists. Yet training courses stress the importance of maintaining our personal artwork alongside therapy practice, and this is widely accepted as a valuable part of a balanced approach to art therapy. Andrea Gilroy has examined this, sometimes difficult, relationship. She outlines her own experiences and reports on her research findings. This article is a reprint of an article originally published in Inscape Spring 1989. It should be noted that at the time the research was being carried out, art therapy training courses ran for only one year full-time or two years part-time.     

The “vegetarian brain”: chatting with monkeys and pigs?

An array of brain regions in the fronto-parietal and temporal lobes cooperates to process observation and execution of actions performed by other individuals. Using functional MRI, we hypothesized that vegetarians and vegans might show brain responses to mouth actions performed by humans, monkeys, and pigs different from omnivores. We scanned 20 omnivores, 19 vegetarians, and 21 vegans while watching a series of silent videos, which presented a single mouth action performed by a human, a monkey, and a pig. Compared to omnivores, vegetarians and vegans have increased functional connectivity between regions of the fronto-parietal and temporal lobes versus the cerebellum during observation of mouth actions performed by humans and, to the same degree, animals. Vegans also had increased connectivity with the supplementary motor area. During human mouth actions, increased amygdala activity in vegetarians and vegans was found. More critically, vegetarians recruited the right middle frontal gyrus and insula, which are involved in social mirroring, whereas vegans activated the left inferior frontal gyrus and middle temporal gyrus, which are part of the mirror neuron system. Monkey mouth actions triggered language network activity in both groups, which might be due to the attempt to decode monkey mouth gesture, with an additional recruitment of associative temporo-occipital areas in vegans, whereas pig mouth actions activated empathy-related regions, including the anterior cingulum. These results support the role of the action observation–execution matching system in social cognition, which enables us to interact not only with our conspecifics but also with species in phylogenetic proximity to humans.
