Association of apolipoprotein E ε4 allele with cognitive impairment in patients with epilepsy and interaction with phenytoin monotherapy

Cognitive impairment implicates many factors beyond phenytoin monotherapy in patients with epilepsy. Apolipoprotein E ε4 allele has been reported to play a role in severe memory impairment that ultimately progresses to Alzheimer's disease (AD); however, knowledge about its role in cognitive impairment in patients with epilepsy is lacking. Our study proposes the possible involvement of the APOE ε4 allele in cognitive impairment in patients with epilepsy which is further worsened by phenytoin monotherapy. Assessment of the APOE ε4 allele in a population with epilepsy will help to identify the patients vulnerable to cognitive impairment and, therefore, the corrective therapy that needs to be addressed.     

Longitudinal study of levodopa in Parkinson's disease: Effects of the advanced disease phase

Thirty‐four patients have been studied from the time of initiation of pharmacological treatment in a long‐term prospective study of levodopa effects and disease progression in Parkinson's disease. Objective motor scoring of the response to levodopa in defined off states was performed every 3 years. The mean time from the initiation of levodopa treatment to the most recent measurements was 18.2 years. Of 8 patients who are still alive, only 3 had none of the features of the advanced disease phase (dementia, hallucinations, frequent falling). Off‐phase motor function worsened at a yearly rate of 1.9% of the maximum disability score, although the plots of the serial scores showed that the magnitude of the levodopa response is well preserved. There was little difference in the rate of progression between patients with tremor‐dominant and non‐tremor‐dominant motor subtypes. Those who developed dementia had more rapid deterioration of motor scores, with significantly worse off‐phase (P = .008) and on‐phase (P = .03) motor function. A graph of serial scores of patients who have died, aligned for time of death, showed an upward curving trend of motor disability in the last 5 years of the disease course. Its advanced phase may reveal that Parkinson's disease has an exponential pattern of progression. © 2013 Movement Disorder Society     

Role of Clinical Images Based Teaching as a Supplement to Conventional Clinical Teaching in Dermatology

Introduction:

Clinical Dermatology is a visually oriented specialty, where visually oriented teaching is more important than it is in any other specialty. It is essential that students must have repeated exposure to common dermatological disorders in the limited hours of Dermatology clinical teaching.

Aim:

This study was conducted to assess the effect of clinical images based teaching as a supplement to the patient based clinical teaching in Dermatology, among final year MBBS students.

Methods:

A clinical batch comprising of 19 students was chosen for the study. Apart from the routine clinical teaching sessions, clinical images based teaching was conducted. This teaching method was evaluated using a retrospective pre-post questionnaire. Students’ performance was assessed using Photo Quiz and an Objective Structured Clinical Examination (OSCE). Feedback about the addition of images based class was collected from students.

Results:

A significant improvement was observed in the self-assessment scores following images based teaching. Mean OSCE score was 6.26/10, and that of Photo Quiz was 13.6/20.

Conclusion:

This Images based Dermatology teaching has proven to be an excellent supplement to routine clinical cases based teaching.     

Seizures and retrograde amnesia with cerebrospinal fluid changes following H1N1 influenza vaccination

Vaccination against H1N1 influenza of healthcare workers of has been a standard measure to control the epidemic in many countries. Most side effects are minor and transient. Guillain Barre Syndrome and optic neuritis have been major concerns. We report a case of seizures with retrograde amnesia associated with cerebrospinal fluid changes following the H1N1 vaccine.     

Suicide in a northern town of Sri Lanka

ABSTRACT– Suicide mortality in a northern town of Sri Lanka for the year 1982 is examined. The rate was 53.5 per 100,000 general population and shows an increasing trend amongst the 15–34 age group. The commonest method was self-poisoning by agrochemicals and insecticides of organophosphorus type. Psychiatric diagnosis, social, economic and political factors are presented. Easy availability of dangerous agrochemicals and rapid social and political changes appear to be of equal importance in producing a high rate of suicide.     

Completed suicide among psychiatric in‐patients with depression in an Australian mental hospital

Up to 45% of completed psychiatric in‐patient suicides have a diagnosis of depression. Twenty‐two completed psychiatric in‐patient suicides with depression, over a 21‐year period, in a large psychiatric hospital in Melbourne, Australia, were examined. The characteristics, including demographic and clinical data, for the completed suicides with depression were compared with a comparison group of ‘alive’ in‐patients with depression. Completed suicide among psychiatric in‐patients with depression was associated with male sex, suicidal thoughts during admission, and fluctuating suicidal ideation or continuous absence of suicidal ideation. Over 40% of completed suicides occurred whilst on approved leave and over 20% after absconding from the hospital. Violent methods (including jumping in front of trains, trams and road traffic, jumping of buildings, hanging and drowning) were used in over 65% of completed suicides. Psychiatric units should be developed away from readily available methods of suicide. In‐patients with suicidal thoughts during the admission and unstable suicidal ideation should be carefully observed to avoid absconding and suicide, and should be carefully assessed prior to granting of leave.
