Chlamydia trachomatis conjunctivitis in the pre-pubertal child.

Much is reported in the literature about the transmission and presentation of Chlamydia trachomatis conjunctival infection in the neonate; however, there is a paucity of information available on infection in the older pre-pubertal child (>3 years of age). We present the case of a 7-year-old girl, referred for assessment at the sexual assault referral centre following the diagnosis of unilateral C. trachomatis conjunctivitis. This child underwent a rigorous multiagency child protection process, with input from medical professionals, social services and the police to investigate the possibility of child sexual abuse (CSA). However, a group consensus was reached that non-sexual close contact transfer of C. trachomatis from the mother was the most likely mode of transmission and cause of infection. We aim to take the reader through the complex path to this conclusion, the approach to sexually transmitted infections and potential CSA and what is currently known about chlamydial conjunctivitis in children beyond the neonatal period.

Fifteen-minute consultation: Apparent vaginal bleeding in the pre-pubertal girl.

A parent or carer's observation of blood in a child's nappy or underwear can be quite alarming for both parent and child and may indicate vaginal bleeding. At first glance, it may be difficult to ascertain whether the bleeding is from the skin, genital tract, urinary tract or anus. Confirmed vaginal bleeding in a pre-pubertal girl is rare but always abnormal and requires comprehensive assessment to determine the cause. Recognition of normal female pre-pubertal anatomy is essential to detect any abnormalities. Appropriate action should be taken according to findings on initial inspection of the ano-genital area. The possibility of child sexual abuse and the need for specialist paediatric sexual offences medicine examination by an FME (Forensic Medical Examiner) or specialist paediatrician should always be considered. This article offers a systematic approach to assessment in pre-pubertal girls with apparent vaginal bleeding which will benefit general paediatricians, emergency department practitioners and GPs.

Organic vs. functional neurological disorders: The role of childhood psychological trauma.

Although the relationship between psychological trauma and medically unexplained symptoms (MUS) is well established, this relationship is less well understood in people with medically unexplained neurological symptoms. In the present study, we set out to compare people with functional neurological disorders, and organic neurological disorders, in terms of childhood and adulthood traumatic events, traumatic stress, emotional dysregulation and symptoms of depression and anxiety. We have hypothesised that those with functional neurological disorders would be more likely to report childhood and adulthood traumatic life events, traumatic symptomatology, emotional dysregulation and symptoms of anxiety and depression, compared to those with organic neurological disorders. Sample consisted of a consecutive series of people with functional neurological disorders and with organic neurological disorders (n=82) recruited from a hospital in Scotland. Participants completed measures of life events, traumatic stress, emotional regulation, anxiety and depression. The two groups were found to significantly differ in relation to all measures, with the MUS group being more likely to report childhood and adulthood life events, more severe emotional dysregulation, traumatic stress and symptoms of anxiety and stress. Logistic regression analysis revealed that exposure to childhood traumatic life events, specifically childhood sexual abuse, and childhood physical neglect, were the only factors which were significantly associated with membership of the medically unexplained neurological symptoms group. Although further research is required to confirm our findings, our results suggest that identifying and addressing the impact of childhood trauma, may alleviate distress and aid recovery from functional neurological disorders.

Stability of 3,4-methylenedioxymethampetamine (MDMA), 4-methylmethcathinone (mephedrone) and 3-trifluromethylphenylpiperazine (3-TFMPP) in formalin solution.

Occasionally, the only postmortem samples available for analysis are contaminated with formaldehyde, either due to embalming prior to sampling or because analysis is carried out only when formalin-fixed tissues retained for histological study are available. Formaldehyde reacts with several drugs of forensic interest that contain either a primary or a secondary amine group to form their N-methyl derivatives. We investigated the stability of 3,4-methylenedioxymethampetamine (MDMA), 4-methylmethcathinone (mephedrone) and 3-trifluromethylphenylpiperazine (3-TFMPP) in formalin solutions using three different formaldehyde concentrations (5, 10 and 20%) and three different pHs (3.0, 7.0 and 9.5). Analysis was performed using high-performance liquid chromatography with diode array detection to determine the percentage degradation of each drug over time, up to 60 days. MDMA, mephedrone and 3-TFMPP are unstable in formalin solutions, with the degradation rate increasing with increasing pH. After 28 days in 20% formalin, pH 9.5, there remained 57% of the initial 3-TFMPP concentration, 11% of the initial MDMA concentration and 4% of the initial mephedrone concentration. Forensic toxicologists should be aware that, when analyzing for these drugs in an embalmed body or in tissues stored in formalin solutions, the methylated form of the secondary amine-containing drug could be a more useful analyte than the parent drug.

Long term outcome of thermal anterior capsulotomy for chronic, treatment refractory depression.

BACKGROUND: There is very limited evidence for the efficacy of any specific therapeutic intervention in chronic, treatment refractory major depression. Thermal anterior capsulotomy (ACAPS) is a rarely performed but established therapeutic procedure for this patient group. While benefit has been claimed, previous ACAPS reports have provided limited information. Detailed prospective reporting of therapeutic effects and side effects is required. OBJECTIVE: To report a prospective study of therapeutic effect, mental status, quality of life, social functioning and neurocognitive functioning in individuals with chronic treatment refractory major depression, treated with ACAPS. METHOD: A prospective case series of 20 patients treated with ACAPS between 1992 and 1999 were reassessed at a mean follow-up of 7.0±3.4 years. Data were collected preoperatively and at long term follow-up. Structural MRI was performed in 14 participants. RESULTS: According to a priori criteria, at long term follow-up, 50% were classified as 'responders' and 40% as 'remitters'. Fifty-five per cent were classified as 'improved'; 35% were 'unchanged'; and 10% had 'deteriorated'. Neurocognitive and personality testing were not significantly different at follow-up. A trend towards improvement in some aspects of executive neuropsychological functioning was observed. Significant adverse effects were infrequent and there were no deaths. CONCLUSIONS: ACAPS may represent an effective intervention for some patients with chronic, disabling, treatment refractory major depression that has failed to respond to other therapeutic approaches. The adverse effect burden within this population was modest, with no evidence of generalised impairment of neurocognitive functioning.

Anorexia nervosa: obsessive-compulsive disorder, obsessive-compulsive personality disorder, or neither?

Anorexia nervosa (AN) is a severe and often chronic disorder with uncertain aetiology and poor prognosis. New approaches to the understanding of the disorder are needed in order to aid the development of more effective treatments. Several authors have suggested that AN has a considerable overlap with obsessive-compulsive disorder (OCD) and that this may reflect common neurobiological, genetic, or psychological elements. However, more recent studies have suggested that AN may have a closer relationship with obsessive-compulsive personality traits such as those found in obsessive-compulsive personality disorder (OCPD). In this paper, evidence for links between the three conditions is reviewed, suggestions for further research are outlined and possible implications for the treatment of AN are presented.
