The importance of leg support for relaxation of the pelvic floor muscles. A surface electromyograph study in healthy girls.

The ability of relaxation is a necessary component for a good function of the pelvic floor muscles (PF). The importance of a relaxation technique for the PF has not been paid much attention in children either in urological examinations or treatments. The aim was to seek postures with optimal relaxation of the PF for use in clinical practice with girls. The relaxation of the PF and adjacent hip and abdominal muscle groups was studied by using surface electromyography (EMG) and a polygraph writer in 20 healthy volunteer girls, 6 and 10 years of age. They were placed in three different postures with their legs supported and unsupported. In postures with supported legs, the relaxation was observed in 94% recorded from the PF and in 97% from the adjacent muscles. EMG amplitudes from the PF and adductor muscles were significantly higher in postures with unsupported legs compared to postures with supported legs (p less than 0.05). The present study indicates that the optimal relaxation of the PF can be achieved by adequate leg support. This can be important to apply particularly in clinical situations such as urodynamic investigations, in uro-biofeedback training and for the design of pelvic floor exercises for girls.

Discontinuation of antiepileptic drugs in children who have outgrown epilepsy: effects on cognitive function.

Cognitive function is frequently impaired in children with epilepsy, compared with age-matched controls. It can be hard to evaluate the significance of various contributory factors. The effects of antiepileptic drugs may be studied in children who have outgrown their epilepsy but are still being treated. A multicenter study to assess various aspects of cognitive function in children with different forms of epilepsy, both during and after treatment with antiepileptic drugs, is currently under way. Definitive results are not yet available; interim analysis of the findings suggests that short-term memory is decreased in all subgroups of children being treated for epilepsy, compared to controls.

Surface electromyography of pelvic floor muscles in healthy children. Methodological study.

Pelvic floor muscle activity was recorded in ten healthy children, aged six to ten years, by using surface electromyography and a polygraph writer. The electromyograms were recorded simultaneously from four electrode pairs on the perineum and three electrode pairs on adjacent muscle groups, i.e. hip and abdominis muscles. The children performed ten different manoeuvres. Necessary prerequisites for this investigatory method include good electrode application, adequate instruction of the child and the child's adjustment to the method. Using the described procedure, it was possible to record pelvic floor muscle activity without any appreciably detectable electrical influence from adjacent muscles. The method sometimes allows selective recording of electromyographic activity between the ventral urogenital and the dorsal anal regions. Therefore both anal and urethral electrode pairs should be used to achieve functional information about the pelvic floor muscles. The envisaged method should be useful as a tool for assessment of pelvic floor muscle exercises in children with voiding disorders.

Experiences of rocket seat ejections in the Swedish Air Force: 1967-1987.

From 1967 to 1987 there were 83 successful and 9 fatal ejections with Saab rocket seats in the Swedish Air Force. Medical consequences and injury factors are reviewed. Thirty-nine survivors had nontrivial injuries; four were seriously injured. The risk for injury has been approximately 50% throughout the period. Two-thirds of the survivors resumed flying within a week, the remainder after up to 1 year, except for three pilots who terminated their flying status.

Peripheral facial palsy in children. A cerebrospinal fluid study.

Seven children and five adults with acute, peripheral facial palsy were investigated by clinical, blood and cerebrospinal fluid (CSF) examinations. Routine blood examinations and blood and CSF serological tests were normal. In all children studied the CSF showed an increased number of mononuclear white cells despite the absence of clinical signs of meningitis in all but one. Two of the twelve patients studied had normal CSF. Contrary to that in adults the outcome in children was excellent, all recovered totally within three months. The present study indicates that acute, peripheral facial palsy is a manifestation of a generalized disorder with subclinical pathology of the central nervous system, and that in children a lumbar puncture should be done, even if there are no signs of meningitis.

Postural sway and gait of children with convergent strabismus.

Postural sway and gait of 35 children with convergent strabismus were tested and compared with those of a control group. They were found to have a short stride-length and single-limb support time in walking, particularly at slow speeds. The girls had a large postural sway, but not the boys. The results suggest a common visuomotor disturbance of eye and limb motor-control.

Child

Development of postural sway in the normal child.

The postural sway was examined in 64 healthy children, aged 3.5 to 17 years. The recordings were done in ordinary standing posture on a force platform, with eyes open and closed. For children younger than 10 years, boys swayed more than girls. The sway amplitude decreased with age for boys, but not for girls. The decrease in sway was equally pronounced in sagittal and lateral direction. The amplitude of sway was higher in sagittal than in lateral direction.

Polymyositis--treatment and prognosis. A study of 107 patients.

One hundred and seven patients with polymyositis or dermatomyositis were followed for an average of 5 years. In 100 patients it was possible to evaluate the effect of treatment with steroids or a combination of steroids and immunosuppressive drugs. Fifty patients improved, 50 did not. Compared with the treatment-resistant group the treatment-responsive patients were of younger age, did not have an associated malignancy or cardiac disease and began treatment within 24 months after the onset of muscular weakness. In the treatment-responsive group the degree of improvement was correlated to the mean dose of steroids given during the first 3 months of treatment. Eighty-seven per cent of surviving responsive patients had no or slight disability at the end of the investigation. The mortality rate was 23% and was highest in the treatment-resistant group. Comparison between different treatment programs was possible and based on the results, a treatment schedule could be recommended. The principles of this schedule are: During the first month high doses of prednisone or prednisolone should be given daily. From the second month, an alternate-day administration can be employed. Tapering to maintenance dose should be gradual and slow. The treatment period should be long. The mean duration in the present series was 27 months.

Quantitative analysis of muscle biopsies from volunteers and patients with neuromuscular disorders. A comparison between estimation and measuring.

106 muscle biopsies from patients with neuromuscular diseases or symptoms were assessed by routine inspection and quantitative examination. Eighty-six specimens were classed as pathological on routine evaluation and 84 on quantitative examination. Eleven specimens that were pathological on routine evaluation were "missed' by quantitative examination. Nine judged normal on routine examination were pathological according to quantitative criteria. Relative measures including the coefficient of variance, the difference between type I and type II fibres, and the difference between fascicles proved valuable for distinguishing between normal and pathological specimens. Quantitative analysis is a valuable complementary method which improves the detection of pathological states in muscle.

Bell's palsy - part of a polyneuropathy?

Some authors have suggested that Bell's palsy should be considered a part of a polyneuritis cranialis and others, reporting Bell's palsy in patients with diabetes mellitus, proposed that it is an overt sign of a subclinical polyneuropathy. To study whether nerves other than the facial nerve were affected, the clinical findings of 112 patients with Bell's palsy were correlated with a quantitative EMG done on an asymptomatic leg muscle. The electromyographic results obtained from these leg muscles showed changes similar to those occurring in peripheral nerve lesions, and the changes correlated well with the degree of facial palsy. The results indicate that the patients with symptomatic facial dysfunction have an acute subclinical polyneuropathy.

Prognosis in Bell's palsy based on symptoms, signs and laboratory data.

A prognostic study was performed in 197 consecutive cases of Bell's palsy. The patients were investigated soon after onset, after one week, after one month and then every second month until total recovery or one year had elapsed. Case histories, clinical findings, and laboratory data were noted. Facial EMG, pure tone audiometry, stapedius reflex test and electrogustometry were performed. The healing time, quality of final healing and amount of sequelae were noted. All data were fed to a computer and correlations were calculated. The final degree of healing was well correlated to the initial EMG, the stapedial reflex test and the electrogustometry but also to the clinical evaluation of the degree of motility at the first visit. A combination of EMG, electrogustometry, stapedial reflex test and evaluation of lacrimation showed a high rate of prognostic value.
