Cognitive impairment in patients diagnosed with tramadol dependence compared to healthy controls.

Cognitive impairment is one of the consequences of substance use. We aimed to estimate the prevalence and correlates of cognitive impairment among patients with tramadol dependence in comparison with healthy controls. The sample consisted of 30 patients with tramadol dependence and 30 healthy controls. Cognitive functions were assessed using Benton Visual Retention Test- revised, Trail Making Test A and B and Wechsler Memory Scale. Patients were also subjected to the Structured Clinical Interview for diagnostic and statistical manual of mental disorders-fourth edition (DSM-IV) Axis I Disorder, the Structured Clinical Interview for DSM-IV Axis II Disorders and the Addiction Severity Index. Results showed that tramadol-dependence patients performed significantly worse than controls regarding cognitive functions, mainly manifested in impaired visual memory, visual reconstruction ability and processing, delayed memory, attention and processing speed, and visual, auditory, immediate, delayed and working memory. We found a nonsignificant negative correlation between cognitive performance and the age of patients or duration of tramadol use. Patients with tramadol dependence were more likely to have cognitive impairment than controls. This may have important clinical implications in determining the right academic and vocational programs for these individuals and adding skills training (e.g. problem solving) to their standard psychosocial treatment.

Characteristics of mentally ill offenders from 100 psychiatric court reports.

BACKGROUND: There is an increasing probability that the psychiatrist will, willingly or not, come into contact with mentally ill offenders in the course of their practice. There are increasing rates of violence, substance abuse and other psychiatric disorders that are of legal importance. Therefore, the aim of this work was to investigate the rates of different mental disorders in 100 court reports and to investigate the characteristics of mentally ill offenders. METHODS: All cases referred from different departments of the legal system to the forensic committee for assessment of legal accountability over 13-months duration were included. A specially designed form was prepared for data collection. Cases were classified into five groups: murder, robbery, financial offences, violent and simple offences and a group for other offences. Data were subjected to statistical analysis and comparisons between different groups of subjects were performed by analysis of variance (ANOVA). RESULTS: Men constituted 93% of cases. In all, 73% of offenders were younger than 40 years old. Schizophrenia cases made up 13% of the total, substance related cases constituted 56% and amphetamine cases alone made up 21%; 10% of cases were antisocial personality disorders, and 51% of cases were classified as having a low education level. Unemployment was found in 34% of cases. The final decision of the forensic committee was full responsibility in 46% of cases and partial responsibility in 11% of cases, with 33% considered non-responsible. A total of 58% of cases had had contact with psychiatric healthcare prior to the offence and in 9% of cases contact had been in the previous 12 weeks. A history of similar offences was found in 32% of cases. In all, 14% of the offences were murders, 8% were sexual crimes, and 31% were violent/simple crimes. CONCLUSIONS: The ability of the legal system to detect cases was good, while the ability of the healthcare system to predict crimes and offences was weak, as 58% of cases had had previous contact with the healthcare system previously. Substance abuse, especially amphetamine abuse, played an important role.

The impacts of substance abuse and dependence on neuropsychological functions in a sample of patients from Saudi Arabia.

BACKGROUND: A lot of studies were directed to explore the relation between drug abuse and neuropsychological functions. Some studies reported that even after a long duration of disappearance of withdrawal or intoxication symptoms, many patients have obvious deterioration of cognitive functions. The aim of this study was to explore the relationship between the substance use disorders and the executive functions. METHODS: Two groups were selected for this study. An experimental group consisted of 154 patients and further subdivided according to the substance used into three different subgroups: opioid, amphetamine and alcohol groups which included 49, 56 and 49 patients respectively. The control group was selected matching the experimental group in the demographic characteristics and included 100 healthy persons. Tools used were: Benton visual retention tests, color trail making test, Stroop colors-word test, symbol digit modalities test, the five dots cognitive flexibility test, and TAM verbal flexibility test. All the data were subjected to statistical analysis RESULTS: The study showed that the group of drug-dependent subjects performed significantly worse than the comparison group on all measures Also, there were significant differences among the subgroups as the alcoholic group was much worse followed by the amphetamine then the opioids groups. Patients with longer duration of dependence and multiple hospital readmissions were much worse in comparison to patients with shorter duration of dependence and less readmission. CONCLUSION: The study confirmed that the functions of specific brain regions underlying cognitive control are significantly impaired in patients of drug addiction. This impairment was significantly related to type of substance, duration of use and number of hospitalization and may contribute to most of behavioral disturbances found in addicts and need much attention during tailoring of treatment programs.

Factors affecting mental fitness for work in a sample of mentally ill patients.

BACKGROUND: Mental fitness for work is the ability of workers to perform their work without risks for themselves or others. Mental fitness was a neglected area of practice and research. Mental ill health at work seems to be rising as a cause of disablement. Psychiatrists who may have had no experience in relating mental health to working conditions are increasingly being asked to undertake these examinations. This research was done to explore the relationship of mental ill health and fitness to work and to recognize the differences between fit and unfit mentally ill patients. METHODS: This study was cross sectional one. All cases referred to Al-Amal complex for assessment of mental fitness during a period of 12 months were included. Data collected included demographic and clinical characteristics, characteristics of the work environment and data about performance at work. All data was subjected to statistical analysis. RESULTS: Total number of cases was 116, the mean age was 34.5 +/- 1.4. Females were 35.3% of cases. The highly educated patients constitute 50.8% of cases. The decision of the committee was fit for regular work for 52.5%, unfit for 19.8% and modified work for 27.7%. The decision was appreciated only by 29.3% of cases. There were significant differences between fit, unfit and modified work groups. The fit group had higher level of education, less duration of illness, and better performance at work. Patients of the modified work group had more physical hazards in work environment and had more work shift and more frequent diagnosis of substance abuse. The unfit group had more duration of illness, more frequent hospitalizations, less productivity, and more diagnosis of schizophrenia. CONCLUSION: There are many factors affecting the mental fitness the most important are the characteristics of work environment and the most serious is the overall safety of patient to self and others. A lot of ethical and legal issues should be kept in mind during such assessment as patient's rights, society's rights, and the laws applied to unfit people.

Effect of near-total thyroidectomy on thyroid orbitopathy due to toxic goiter.

BACKGROUND: The relative merit of surgery in the treatment of Graves' ophthalmopathy as well as the extent of surgical resection are still matters of debate. This study aimed at reporting an assessment of the impact of near-total thyroidectomy on the course of ophthalmopathy including exophthalmos. METHODS: A total of 20 patients with thyrotoxic goiters who were suffering from mild to moderate exophthalmos were enrolled in this prospective study. Preoperative evaluation of ophthalmopathy was accomplished through the NOSPECS classification, magnetic resonance imaging (MRI) for measuring the extraocular muscle diameters, and measurement of the exophthalmos using Hertel's exophthalmometer. Ophthalmopathy including exophthalmos was reevaluated 6 months after operation using the same parameters. RESULTS: Clinical activity evaluation, exophthalmometry, and extraocular muscles measurement by MRI revealed that most of the patients experienced improvement of their ophthalmopathy (65%). This improvement was statistically significant. In addition, no major postoperative complications were observed. However, the study, unlike a number of reported retrospective ones, failed to specify any statistically significant prognostic factors affecting the course of ophthalmopathy; this may have been due to the limited number of patients. In addition, all of the patients were of relatively young age and thyrotoxic, and most were female and nonsmoking. CONCLUSIONS: In addition to the fact that near-total thyroidectomy adds the advantages of total thyroidectomy (no recurrence) to those of subtotal thyroidectomy (low incidence of temporary and permanent hypoparathyroidism), it has a significant positive impact on thyroid-associated orbitopathy.
