Comparison and item analysis of the MESSY for autistic and normal children

Seventeen autistic children were matched for age, race, and sex with 17 nonautistic children, and group differences in social skills were assessed. Appropriate social skills and levels of inappropriate assertiveness/impulsiveness were assessed and evaluated using the Matson Evaluation of Social Skills with Youngsters (MESSY). Significant differences in both the appropriate and inappropriate social behaviors displayed by the two groups were found. The implications of these results are discussed.     

Serum cholesterol and impulsivity in personality disorders

Decreased serum cholesterol has been associated with impulsive aggressive behaviors. This study was designed to explore the relationship between serum cholesterol levels and measures of impulsive aggression in personality disordered patients. Forty-two personality disordered patients (14 borderline personality disorder, 28 other personality disorders) were included. Fasting serum cholesterol was measured by standard enzymatic assay. An ANOVA was performed with factors of gender and diagnosis, looking at two-way interactions between the factors and serum cholesterol. Patients with borderline personality disorder were found to have significantly lower serum cholesterol than non-borderline personality disorders. A significant interaction effect was also seen between gender and diagnosis with the male patients having lower cholesterol levels. This study suggests there may be a relationship between borderline personality disorder and low serum cholesterol.     

Sigmoidoscopy in minor lower gastrointestinal bleeding

The role of sigmoidoscopic examination in the diagnosis, evaluation, and treatment of minor lower gastrointestinal bleeding was investigated. A hundred patients with minor rectal bleeding were examined by rigid sigmoidoscopy under general anaesthesia between January 1989 and July 1996. Patients who had bleeding secondary to infections, anal fissure, or haemorrhoids were excluded from study. Patients were reviewed retrospectively according to their diagnosis and endoscopic and histopathological findings. Twenty nine of these patients were girls and 71 boys; their ages ranged between 8 month and 14 years (mean 7.2 years). Endoscopic pathological findings were established in 60 patients; 32 had rectal polyps, 16 non-specific proctitis, four solitary rectal ulcers, three internal haemorrhoids, two ulcerative colitis, two Hirschsprung's enterocolitis, and one haemangioma. It is concluded that sigmoidoscopic examination should be performed for the diagnosis, prognosis, and choice of treatment in patients with minor rectal bleeding and the diagnosis should be confirmed histopathologically.     

Prognosis Scores of Tokuhashi and Tomita for Patients With Spinal Metastases of Renal Cancer

Background Retrospective evaluation of the prognosis scores of Tokuhashi and Tomita for life expectancy in 37 consecutive patients with spinal metastases secondary to renal cancer who underwent surgery. The score of Tokuhashi, composed of six parameters, each rated from zero to two, has been proposed in 1990 for the prognostic assessment of patients with spinal metastases. In 2001, Tomita et al. created another prognostic score, composed of three parameters, growth behaviour of the primary tumor (slow, moderate and rapid) and the evidence of visceral and bony metastases. Methods Thirty-seven patients, surgically treated for vertebral metastases secondary to renal cancer were studied. The scores according to Tokuhashi and Tomita were calculated for each patient. Results Applying the Tokuhashi Score for the estimation of life expectancy of renal cancer patients with vertebral metastases was found to provide very reliable results with a statistically high significance. The analysis according to Tomita showed no correlation between predicted and real survival. The statistical analysis did not show any significance. Conclusion For surgical decisions in renal cancer patients with spinal metastases, the prognostic score of Tokuhashi appears to be much more valuable than the Tomita score.     

Topographical presentation of dental wear as arches in a French mediaeval population

The diversity of notation systems for recording dental characteristics and the means used to display them makes comparisons and interdisciplinary collaboration difficult.ObjectiveThe aim of the present study is to propose the use of a method employed by experts worldwide but which may be new to bioarchaeologists. Since 1971 we have used the International Dental Federation (FDI) system, which provides the location of dental characteristics and the morphotype of each tooth at the same time, thus avoiding the need to specify upper or lower, and right or left to state the tooth position in the dental arch.DesignTo demonstrate the use of the FDI system, we applied it to the study of dental wear in a mediaeval Mediterranean skeletal sample from France consisting of 58 paired mandibles and maxillae belonging to 29 female and 29 male adults and divided into two age groups: young or aged 20–30 years, and mature or aged over 30 years. Tooth wear was recorded according to Brabant's index, which consists of four levels and four directions. Data were displayed in the form of curves, according to the FDI and taking age and sex into account.ResultsAnalysis of the results shows a tooth wear distribution that is significantly different between upper and lower horizontal and oblique directions in females and males, and between upper and lower horizontal and oblique heavy wear in females and males. Moreover, a significantly asymmetrical horizontal and oblique distribution of wear was found in the young adult group. Thus, the use of criteria defined by precise reference points for recording data, and displaying results in the form of curves, makes comparison using superimposition easy and reliable and permits a more objective study of tooth wear.ConclusionsFurthermore, using a notation system that is employed worldwide helps to build multidisciplinary projects, and offers the possibility of comparing large amounts of data easily, which should provide enhanced data for bioarchaeology in the future.
