Alfred Kinsey: Asperger disorder
Autism and Creativity is a stimulating study of male creativity and autism, arguing that a major genetic endowment is a prerequisite of genius, and that cultural and environmental factors are less significant than has often been claimed. Autism and Creativity will prove enthralling reading not only for professionals and students in the field of autism and Asperger’s syndrome, but for anyone wanting to know how individuals presenting autistic features have on many occasions changed the way we understand society. This is quite simply the best book I have read on autism . . . Fitzgerald is clearly an experienced clinician and his deep understanding of the spectrum of autism conditions comes across in his writings. But he is also an exceptional scholar. Professor Simon Baron-Cohen, Cambridge University.
We determined the reported prevalence of infectious osseous complications due to the use of bone anchors for suture fixation in female pelvic reconstructive procedures. In addition, the type and method of bone anchors as well as the reported pathogens associated with osseous infections were reviewed.
Primary reported series of female pelvic reconstructive procedures involving bone anchor suture fixation referenced in Index Medicus from January 1990 to July 2000 were extracted using the MEDLINE bibliographic database on English language articles involving humans. All case reports of infectious osseous complications due to bone anchor use in female reconstructive procedures were also reviewed during this period.
Since the inception of bone anchor suture fixation for female pelvic reconstructive procedures 10 years ago, the overall prevalence of related infectious complications has been 6 cases in 1,018 procedures (0.6%). This type of adverse event developed between followup weeks 1 and 24. The prevalence of suprapubic bone anchors has been 6 cases in 698 procedures (0.86%). For transvaginal bone anchor procedures no infectious cases have been reported in the combined series of 314 procedures and the same is true for 1 reported case of sacral bone anchor placement in 6 procedures. No statistical difference was noted in regard to the prevalence of infection in procedures involving suprapubic bone anchors and transvaginal bone anchor combined with sacral bone anchor placement (Fisher's exact test p = 0.19). The organisms reported in case reports suggest a coliform, skin or hematogenous source for contamination of the bone anchor site.
An infectious bone anchor complication in female pelvic reconstructive procedures is an uncommon event with a reported prevalence of 0.6%. Currently there is no evidence of differences in the prevalence of osseous complications after transvaginal versus suprapubic bone anchor fixation. Preoperative broad-spectrum antibiotics are recommended to decrease the potential of infectious bone anchor complications.
The theory of mind account of autism has been remarkably successful in making specific predictions about the impairments in socialization, imagination and communication shown by people with autism. It cannot, however, explain either the non-triad features of autism, or earlier experimental findings of abnormal assets and deficits on non-social tasks. These unexplained aspects of autism, and the existence of autistic individuals who consistently pass false belief tasks, suggest that it may be necessary to postulate an additional cognitive abnormality. One possible abnormality - weak central coherence - is discussed, and preliminary evidence for this theory is presented.
The cognitive study of the underlying mental abnormalities in autism has advanced rapidly, while the biological study of the underlying brain abnormalities and of putative genetic mechanisms is lagging somewhat behind. However, the linking of cognitive and biological studies has become a real possibility. Developmental cognitive neuroscience has transformed our understanding of this enigmatic disorder, which was once misguidedly thought to be caused by maternal rejection. The hypothesis of a specific theory of mind deficit was a crucial step in this process. It explains the puzzle of the characteristic social and communication impairments of autism and allows for the fact that they can coexist with good general abilities. This hypothesis has been widely accepted and a start has been made at pinpointing the brain basis of theory of mind. The non-social impairments of autism have now become a major focus for cognitive research. One theory proposes dysfunction in executive processes, in an attempt to explain repetitive behaviour and inflexibility. Another theory proposes weak information integration, in an attempt to explain narrow interests and special talents. Autism research has thus stimulated ideas on important mind-brain systems that may be dedicated to the development of social awareness, executive functions and integrative processing.
We examined the claim that children with autism have a "weak drive for central coherence" which biases them towards processing information at an analytic rather than global level. This was done by investigating whether children with autism would rapidly and automatically enumerate a number of dots presented in a canonical form, or count each dot individually to obtain the total. The time taken to count stimuli was compared across three participant groups: children with autism, children with moderate learning difficulties, and normally developing children. There were 22 children in each group, and individuals were matched across groups on the basis of verbal mental age. Results implied that children with autism did show a tendency towards an analytic level of processing. However, though the groups differed on measures of counting speeds, the number or children showing patterns of global or analytic processing did not differ significantly across the groups. Whether these results implicate a weak drive for central coherence in autism, which is both specific to, and pervasive in the disorder, is discussed.
