Translation of the Leisure Satisfaction Scale into French: a validation study

Few standardized instruments are available for clients who speak languages other than English. The purpose of the study was to present and describe the process of translating an English standardized assessment into another language. Using the translation/validation methodologies described by Haccoun (1987) and Vallerand (1989), the Leisure Satisfaction Scale (LSS) was translated into French and then statistically validated. All correlations between both language versions of the LSS were found to be significant at the 0.01 level. Confirmatory factor analysis results were positive. Study findings indicate that the Haccoun (1987) and Vallerand (1989) methodologies provide clinicians with another option for ensuring culturally sensitive and relevant evaluations. Further research is needed to globally assess the measurement properties of the French version of this instrument.     

Childhood medulloblastoma in northwest England 1954 to 1997: incidence and survival

The incidence, survival patterns, and presenting symptoms of children with medulloblastoma were studied. Data were ascertained from the Manchester Tumour Registry which is population-based and has collected data on all childhood malignancies in northwest England since 1954. Incidence rates standardized to the European standard population were calculated and Poisson regression models were used to examine temporal changes in the incidence rates during the period 1954 to 1997. Kaplan-Meier survival curves were derived and used to study changes in survival patterns. World-standardized incidence rates were 5.5 per million child years in males and 3.4 per million child years in females. Incidence rates increased from the 1950s to the 1980s but have declined recently. The 5-year survival rate has improved from 29 to 58% with similar rates for males and females. The 1-year survival rate has also improved, but females had worse survival at this point (58%) than males (75%). The type of symptom or sign at presentation is strongly affected by age, with 10 of the 22 recorded symptoms or signs showing significant age differences. The older the child is, the more likely is the presentation to show pressure features of headache, vomiting, and ophthalmic signs. Younger children present with non-specific features such as lethargy, behavioural disturbance, or increasing head size. Ataxia is seen in about 75% of children across the age range.     

Comparative effects of mirtazapine and fluoxetine on sleep physiology measures in patients with major depression and insomnia

BACKGROUND: Sleep complaints are common in patients with major depressive disorder (MDD). Both MDD and antidepressant drugs characteristically alter objective sleep measures. This study compares the effects of mirtazapine and fluoxetine on sleep continuity measures in DSM-IV MDD patients with insomnia. METHOD: Patients (N = 19) received initial baseline polysomnography evaluations over 2 consecutive nights. Subjects were randomly assigned to either fluoxetine (20-40 mg/day) or mirtazapine (15-45 mg/day) treatment for an 8-week, double-blind, double-dummy treatment trial. Single-night polysomnograms were conducted at weeks 1, 2, and 8, with depression ratings assessed at baseline and weeks 1, 2, 3, 4, 6, and 8. Statistical analysis was performed by repeated-measures analysis of variance followed by Dunnet's post hoc analyses. RESULTS: Patients receiving mirtazapine (N = 8) had significant improvement in objective sleep physiology measures at 8 weeks. Improvements in sleep latency, sleep efficiency, and wake after sleep onset were significant after only 2 weeks of mirtazapine treatment. No significant changes in sleep continuity measures were observed in the fluoxetine group (N = 11). Both groups improved clinically in mood and subjective sleep measures from baseline, with no differences between groups. CONCLUSION: These data demonstrate the differential effects of mirtazapine and fluoxetine, with significant improvement in favor of mirtazapine, on objective sleep parameters in MDD patients with insomnia.     

Altered venous function and deep venous thrombosis following proximal femoral fracture

The effect of surgery for femoral neck fracture on lower limb venous blood flow and its relationship to deep vein thrombosis was investigated in 179 patients. Blood flow was measured using strain gauge plethysmography before surgery, in the 1st week after surgery, and at 6 week review. There was a significant reduction in both venous outflow and venous capacitance, affecting both fractured and non-fractured legs but significantly greater in the fractured leg. Venous function remained significantly impaired in both lower limbs 6 weeks after surgery.There was a significant correlation between the reduction in venous function and the development of deep vein thrombosis.     

Normal fetal pelvis: important factors for morphometric characterization with US

PURPOSE: To prospectively evaluate iliac angle and iliac length in a large number of normal fetuses and to identify factors that may influence these measurements. MATERIALS AND METHODS: At antenatal ultrasonography (US) in 356 fetuses, the iliac angle and iliac length were measured at two axial levels (superior and inferior). In mixed linear models, the statistical significance and magnitude of effect on the measurement of iliac angle and iliac length were estimated for gestational age, fetal sex, maternal diabetes status, axial level, and spine position relative to the transducer. RESULTS: Statistically significant effects were found for gestational age, axial level, and spine orientation but not for fetal sex or maternal diabetes status. The iliac angle was found to decrease by 15.7 degrees from the superior to inferior portion of the pelvis, decrease by approximately 0.37 degrees /wk, and decrease by as much as 15.6 degrees when the spine is directed to the side. Iliac length was found to increase by 0.8 mm/wk from 13 weeks to term, decrease by 1.2 mm from the superior to the inferior portion of the pelvis, and increase by as much as 1.29 mm when the spine is not directly subjacent to the transducer. CONCLUSION: The axial level of measurement, gestational age, and spine orientation must be accounted for if these morphometric indexes are used to discriminate fetuses with and those without Down syndrome.     

Imaging assessment of anterior knee pain and patellar maltracking

Anterior knee pain is a common complaint in the orthopaedic clinic. The differential diagnosis is wide and the principal goal of initial assessment is to detect remediable causes. The majority of patients do not have a specific disease and increasingly interest has focused on the role of patello-femoro-tibial morphology and of patellar maltracking in the aetiology of anterior knee pain. Classification in this group of patients is poor and there is no uniform agreement on which patient groups benefit from treatment and which treatment is best. Much of the literature involves relatively small numbers of patients, is poorly controlled and there is little agreement on outcome measures [1, 2]. The purpose of this review is to outline the current status of the imaging assessment of recalcitrant anterior knee pain with particular reference to patellar maltracking.

The international collaborative study of maternal phenylketonuria: status report 1994

Neonatal screening for phenylketonuria (PKU) has created a problem as females with PKU are reaching child-bearing age. Surveys have revealed that maternal phenylalanine blood concentrations greater than 1200 μmol/l are associated with fetal microcephaly, congenital heart defects and intrauterine growth retardation. It is estimated that as many as 3000 hyperphenylalaninemic females may be at risk of producing these fetal abnormalities. To examine this problem, the international maternal PKU collaborative study was developed to evaluate the efficacy of a phenylalanine-restricted diet in reducing fetal morbidity. Preliminary findings have indicated that phenylalanine restriction should begin before conception for females with PKU planning a pregnancy. Dietary control should maintain maternal blood phenylalanine levels between 120 and 360 μmol/l and should provide adequate energy, protein, vitamin and mineral intake. Pregnant hyperphenylalaninemic females who achieved metabolic control after conception or by the 10th week of pregnancy had a better offspring outcome than anticipated. The results of 402 pregnancies are reviewed.     

Liposomal amphotericin B in hepatic candidosis

A 4 year old girl treated with a standard chemotherapy protocol for acute lymphoblastic leukaemia developed hepatic candidosis during the consolidation phase. This relapsed after a prolonged course of amphotericin B and flucytosine. An eight week course of liposomal amphotericin produced a marked clinical improvement which was sustained for one year. A subsequent relapse was associated with transformation to myelodysplastic leukaemia.     

Induction of labour after 1 previous Caesarean section

The aim of this study was, after induction of labour in women with a previous Caesarean section, to compare the outcome in women with a history of a previous vaginal delivery with women who had never delivered vaginally. A retrospective analysis was performed over a 2-year period, in a Dublin teaching hospital. One hundred and three women who had had 1 previous lower segment Caesarean section had labour induced. Particular attention was given to delivery outcome, history of a vaginal delivery, cervical effacement at induction, influence of epidural analgesia, indication for induction and incidence of uterine rupture. The repeat Caesarean section rate after induction was 20.4%. Of the 51 women who had never previously delivered vaginally, the repeat section rate was 37.3% compared with only 3.9% of the 52 women who had previously delivered vaginally (p < 0.01). Fourteen women who had never delivered vaginally had an uneffaced cervix at induction and the repeat Caesarean section rate in this group was 64.3%. The commonest indication for induction was a postdates pregnancy. The use of epidural analgesia was greater in women who had never delivered vaginally. There were 2 cases of uterine scar rupture. Induction of labour following Caesarean section is associated with a significantly higher incidence of repeat Caesarean section in women who have not had a previous vaginal delivery. If the cervix is not effaced at induction, the repeat Caesarean section rate is higher than if the cervix has started to efface.
