RATIONALE: The long-term outcome of idiopathic macrocephaly is presently unknown. METHODS AND RESULTS: In the current study (n=15), MRI conducted at long-term review showed regression of orbito-frontal extradural collections and normal or slightly enlarged ventricular space compared to infant examination. Head circumference had normalised in all but one participant. Neuropsychological assessments of nine participants showed general intellectual ability within the normal range in the majority of participants; however, specific deficits in attention were evident. Clinical interviews conducted with a smaller sub-group revealed anecdotal histories of behavioural difficulties and reading or arithmetic difficulties in half of the total sample. CONCLUSIONS: Prospective review studies such as this indicate that abnormal radiological findings in infancy are not necessarily predictive of neurodevelopmental problems and may reflect a normal variant. However, while overall intellectual ability may be within average limits in this diagnostic sample, considerable individual variations remain in specific areas of neuropsychological function. 相似文献

The Wechsler Adult Intelligence Scale-Revised (WAIS-R) Verbal IQ-Performance IQ (VIQ-PIQ) discrepancy and a number of indices of intersubtest scatter were examined in 25 subjects with a history of traumatic brain injury (TBI) and magnetic resonance imagining (MRI) evidence of structural brain abnormality. Abnormal VIQ-PIQ differences and scatter index values were identified by referring to published normal base rates. Only 16% of the subjects were identified as abnormal on any one of these WAIS-R measures, which suggests these measures are largely insensitive to the presence of structural brain abnormality in TBI. 相似文献

BACKGROUND: The pattern of growth of the uterus was examined by ultrasound examinations of 358 girls who attended a paediatric endocrine outpatient department but were shown not to have any endocrine defect. METHOD: The uterus was measured in length and width at the cervix and at the fundus (cm). Endometrial thickness was measured (mm). Scans were divided by Tanner breast stage and the dimensions compared by one way analysis of variance (ANOVA, with the Student Newman Keuls post hoc test). RESULTS: There was an increase in uterine length, diameter of the fundus, and endometrial thickness at each breast stage from 1 to 5 (ANOVA, p < 0.05), and in the diameter of the cervix with each breast stage from 1 to 4 (ANOVA, p < 0.05). The ratio of the fundus to the cervix increased from 0.95 to 1.29 between breast stages 1 and 4. CONCLUSION: The onset of puberty is marked by an increase in the dimensions of the uterus and in endometrial thickness, but also by a change in the shape of the uterus from a tubular to a pear shaped organ. 相似文献

Since indium-111 white blood cell (In-111 WBC) scintigraphy is often used to evaluate for osteomyelitis in bone fractures, it is important to know if noninfected fractures have In-111 WBC uptake. Twenty-seven noninfected closed fracture sites in 19 patients were prospectively evaluated with technetium-99m methylene diphosphonate bone scintigraphy and In-111 WBC scintigraphy. In-111 WBC uptake was present in 41% of the 27 sites. In the 11 positive sites, the In-111 WBC uptake was 1+ (definite but minimal) in 55%, 2+ (moderate) in 36%, and 3+ (marked) in 9%. The visual intensity of the radioactive uptake on In-111 WBC scintigrams relative to that on bone scintigrams was less in 82%, equal in 9%, and greater in 9%. The visual size of the area of uptake on In-111 WBC scintigrams and bone scintigrams was smaller in 36%, equal in 55%, and greater in 9%. Factors that may help distinction of In-111 WBC uptake due to fracture alone from infection associated with fracture are discussed. 相似文献

The Parsons visual acuity test (PVAT) uses modified Allen test targets for visual acuity assessment in young children and persons who are difficult to test. Using this method, we were able to obtain a visual acuity threshold in 44% of 18- to 24-month-old children and in 90% of children aged 25 to 36 months. At all ages tested, the mode for visual acuity was 20/30; however, the percentage of those with 20/20 increased with age. The decision whether to refer was correctly made by means of the PVAT criterion 83% of the time. 相似文献
