Selected AbstractsIncidence and diagnostic diversity in first-episode psychosisACTA PSYCHIATRICA SCANDINAVICA, Issue 4 2010R. Reay Reay R, Mitford E, McCabe K, Paxton R, Turkington D. Incidence and diagnostic diversity in first-episode psychosis. Objective:, To investigate the incidence and range of diagnostic groups in patients with first-episode psychosis (FEP) in a defined geographical area. Method:, An observational database was set up on all patients aged 16 years and over presenting with FEP living in a county in Northern England between 1998 and 2005. Results:, The incidence of all FEP was 30.95/100 000. The largest diagnostic groups were psychotic depression (19%) and acute and transient psychotic disorder (19%). Fifty-four per cent of patients were aged 36 years and over. Patients with schizophrenia spectrum disorder only accounted for 55% of cases. Conclusion:, This clinical database revealed marked diversity in age and diagnostic groups in FEP with implications for services and guidelines. These common presentations of psychoses are grossly under researched, and no treatment guidelines currently exist for them. [source] Adults with intellectual disabilities: prevalence, incidence and remission of self-injurious behaviour, and related factorsJOURNAL OF INTELLECTUAL DISABILITY RESEARCH, Issue 3 2009S.-A. Cooper Abstract Background Self-injurious behaviour (SIB) is a serious condition, with implications for the person, their family and financial costs to the state providing care. The previously reported prevalence of SIB has ranged from 1.7% to 41%, or 1.7%,23.7% in community studies. There has been little study of remission rate, and incidence has not previously been reported. SIB has been reported to be individually associated with lower ability, autism and communication impairments, but given the inter-relationships between these three factors, it is not known whether they are independently associated with SIB. This study investigates the point prevalence, incidence and remission rates of SIB among the adult population with intellectual disabilities (ID), and explores which factors are independently associated with SIB. Method A prospective cohort study design was used in a general community setting. The participants were all adults (16 years and over) with ID in a defined geographical area. Individual assessments were conducted with all participants. Results The point prevalence of SIB (as defined by DC-LD) was 4.9%, the two-year incidence was 0.6%, and two-year remission rate was 38.2%. Independently related to SIB were: lower ability level, not living with a family carer, having attention deficit hyperactivity disorder, visual impairment, and not having Down syndrome. Other factors, including communication impairment, autism, and level of deprivation of the area resided within, were not related. Conclusions SIB is not as enduring and persistent as previously thought; a significant proportion gains remission in this time period. This should provide hope for families, paid carers and professionals, and reduce therapeutic nihilism. Our study is a first tentative step towards identifying risk-markers for SIB, and developing aetiological hypotheses for subsequent testing. The extent to which SIB may be a relapsing-remitting (episodic) condition requires further investigation, so does further hypothesis-based investigation of factors that might be predictive of incidence of, and remission from, SIB.

Björkegren Abstract. Objectives., To study the effects of vitamin B12 and folic acid treatment on haematological measures, reported symptoms and clinical findings over a 3-year period. Design., A longitudinal two-cohort study. Setting., A mid-Swedish community. Subjects., A 20% random sample of persons 70 years or older in a defined geographical area were invited to a survey (n = 266). Sixty-nine persons who had serum cobalamin <300 pmol L,1 and serum methylmalonic acid (MMA) ,0.37 ,mol L,1 or serum total homocysteine (tHcy) ,15 ,mol L,1 and who had no vitamin B12 or folic acid substitution were selected for treatment. Main outcome measures., Serum cobalamin, folate, MMA and tHcy. Presence of gastrointestinal, neurological, psychiatric and some other symptoms, obtained by questionnaire, and Mini Mental State Examination (MMSE) score, vibration sense measurement and findings at a physical examination. Results., After combined vitamin B12,folic acid treatment, all persons normalized their serum tHcy and MMA levels and the effect remained after 3 years. The study design allowed separation of pure vitamin B12 deficiencies from folate and combined deficiencies. There was a tendency towards improvement of vibration sense, especially in the long nerve paths, and improvement of neurological symptoms and oral mucosa findings. No improvement was seen for other symptoms, reflex activity or MMSE score. Conclusions., Vitamin treatment of elderly people in the early phase of the condition may reverse damage that otherwise would become irreversible. If initiated, the treatment should be combined with vitamin B12 and folic acid. [source] Collection, use, and protection of population-based birth defects surveillance data in the united states,BIRTH DEFECTS RESEARCH, Issue 12 2007Cara T. Mai Abstract Birth defects surveillance systems collect population-based birth defects data from multiple sources to track trends in prevalence, identify risk factors, refer affected families to services, and evaluate prevention efforts. Strong state and federal public health and legal mandates are in place to govern the collection and use of these data. Despite the prima facie appeal of "opt-in" and similar strategies to those who view data collection as a threat to privacy, the use of these strategies in lieu of population-based surveillance can severely limit the ability of public health agencies to accurately access the health status of a group within a defined geographical area. With the need for population-based data central to their mission, birth defects programs around the country take their data stewardship role seriously, recognizing both moral and legal obligations to protect the data by employing numerous safeguards. Birth defects surveillance systems are shaped by the needs of the community they are designed to serve, with the goal of preventing birth defects or alleviating the burdens associated with them.
