Influence of single peer interventions on the recovery attitude of persons with a psychiatric disability

This study examined the influence of single peer to peer interventions on participants' recovery attitudes.

Screening for sleep disorders in community pharmacies--evaluation of a campaign in Switzerland

BACKGROUND: In 2003 the Swiss federation of pharmacists organized a campaign "sleep disturbances--daytime sleepiness". The goal was to assist pharmacy clients in detecting likely causes of any sleep disturbance or daytime sleepiness through a free of charge screening, and to deliver targeted counselling. For pharmacy practice there are no screening or triage guidelines to assess the severity of sleep and wakefulness disturbances and potential causes for those disturbances. In this paper the outcome of the campaign in terms of feasibility, participation, observed response patterns, sale of over-the-counter (OTC) sleeping pills, and counselling activities is evaluated. METHODS: The Stanford sleep disorders questionnaire and the Epworth sleepiness scale served to identify patterns of symptoms suggestive of four major categories of sleep disorders. The questionnaires were posted on a web-site and the clients' data were entered online in the pharmacies. A report was automatically generated and immediately available online to the pharmacists. The pharmacists documented separately their counselling activities in a pharmacist's activity report. RESULTS: Six hundred and twenty-two (23%) of 2743 pharmacy clients had response patterns suggestive of obstructive sleep apnoea, 418 (15%) of restless-legs-syndrome, 39 (1%) of a sleep disorder potentially associated with a psychiatric condition and 79 (3%) of narcolepsy. An Epworth sleepiness score >10 points was found in 567 (21%). After screening, 2345 (86%) pharmacy clients received targeted counselling. Only 216 (8%) purchased an OTC sleeping pill and 704 (26%) were recommended to consult a physician, but of these, 446 (63%) were already under medical supervision. CONCLUSIONS: The online screening tool for sleep disorders and daytime sleepiness was successfully introduced in Swiss pharmacies. Pharmacies were able to assess the pattern of individual sleep disorders and to identify a possible cause in nearly one-third of the cases.

Psychiatric comorbidity in patients with spasmodic dysphonia: a controlled study

OBJECTIVES: To study the prevalence of psychiatric comorbidity assessed by a structured clinical interview in patients with spasmodic dysphonia (SD) compared with patients suffering from vocal fold paralysis (VFP). METHODS: In 48 patients with SD and 27 patients with VFP, overall psychiatric comorbidity was studied prospectively using the Structured Clinical Interview for DSM-IV Axis I disorders. Physical disability and psychometric variables were assessed with standardised self-rating questionnaires. RESULTS: 41.7% of SD subjects and 19.5% of the control group met DSM-IV clinical criteria for current psychiatric comorbidity (p<0.05). Significant predictors of psychiatric comorbidity in SD were severity of voice impairment and subjective assessment of "satisfaction with health". As a limitation, the severity of voice impairment in patients with SD was nearly twice as high, and their illness had lasted nearly twice as long. CONCLUSIONS: We found a high prevalence of psychiatric comorbidity in patients with SD. The significant correlation between current psychiatric comorbidity and the extent of voice pathology may point to an especially strong interaction between somatic and psychiatric complaints in SD.

Early co-occurrence of a neurologic-psychiatric disease pattern in Niemann-Pick type C disease: a retrospective Swiss cohort study

BackgroundNiemann-Pick disease type C (NP-C) is a rare autosomal recessive disorder of lysosomal cholesterol transport. The objective of this retrospective cohort study was to critically analyze the onset and time course of symptoms, and the clinical diagnostic work-up in the Swiss NP-C cohort.MethodsClinical, biochemical and genetic data were assessed for 14 patients derived from 9 families diagnosed with NP-C between 1994 and 2013. We retrospectively evaluated diagnostic delays and period prevalence rates for neurological, psychiatric and visceral symptoms associated with NP-C disease. The NP-C suspicion index was calculated for the time of neurological disease onset and the time of diagnosis.ResultsThe shortest median diagnostic delay was noted for vertical supranuclear gaze palsy (2y). Ataxia, dysarthria, dysphagia, spasticity, cataplexy, seizures and cognitive decline displayed similar median diagnostic delays (4¿5y). The longest median diagnostic delay was associated with hepatosplenomegaly (15y). Highest period prevalence rates were noted for ataxia, dysarthria, vertical supranuclear gaze palsy and cognitive decline. The NP-C suspicion index revealed a median score of 81 points in nine patients at the time of neurological disease onset which is highly suspicious for NP-C disease. At the time of diagnosis, the score increased to 206 points.ConclusionA neurologic-psychiatric disease pattern represents the most characteristic clinical manifestation of NP-C and occurs early in the disease course. Visceral manifestation such as isolated hepatosplenomegaly often fails recognition and thus highlights the importance of a work-up for lysosomal storage disorders. The NP-C suspicion index emphasizes the importance of a multisystem evaluation, but seems to be weak in monosymptomatic and infantile NP-C patients.

Evaluation of HA-fibrin-based hydrogel for restoration of degenerated intervertebral disc

Introduction: Intervertebral disc degeneration is associated with loss of nucleus pulposus (NP) tissue and reduced disc height[1]. A number of therapies, including synthetic and natural biomaterials, have been developed to restore full disc function and to minimize the pain and disability caused by this disease. Fibrin-based biomaterials are used as a replacement for NP or as a cell carrier for tissue engineering approaches[2]. While the behavior of such gels is well-characterized from a material point of view, little is known about their contribution to intervertebral disc (IVD) restoration under dynamic loads. The aim of the present study is the evaluation of a hyaluronic acid fibrin-based hydrogel (ProCore) used to repair an in vitro model of disc degeneration under dynamic loading. Methods: In vitro model of disc degeneration was induced in intact coccygeal bovine IVD by papain digestion of the NP as previously described[3]. In order to characterize fibrin hydrogels, four experimental groups were considered: 1) intact IVD (control), 2) IVD injected with PBS, 3) injection of hydrogels in degenerative IVD and 4) injection of hydrogels in combination with human bone marrow-derived mesenchymal stem cells (MSC) in degenerative IVD. All of the groups were subjected to dynamic loading protocols consisting of 0.2MPa static compression superimposed with ±2° torsion at 0.2Hz for 8h per day and maintained for 7 days. Additionally, one group consisted of degenerative IVD injected with hydrogel and subjected to static compression. Disc heights were monitored after the duration of the loading and compared to the initial disc height. The macrostructure of the formed tissue and the cellular distribution was evaluated by histological means. Results: After one week of loading, the degenerative IVD filled with hydrogel in combination with MSC (dynamic load), hydrogels (dynamic load) and hydrogels (static load) showed a reduction in height by 30%, 15% and 20%, respectively, as compared to their initial disc height. Histological sections showed that the HA-fibrin gel fully occupied the nucleotomized region of the disc and that fibrin was effective in filling the discontinuities of the cavity region. Furthermore, the cells were homogenously distributed along the fibrin hydrogels after 7 days of loading. Discussion: In this study, we showed that fibrin hydrogels showed a good integration within the papain-induced model of disc degeneration and can withstand the applied loads. Fibrin hydrogels can contribute to disc restoration by possibly maintaining adequate stiffness of the tissue and thus preventing disorganization of the surrounding IVD. References: 1.
