Children with congenital deficiencies or acquired amputations of the lower limbs: functional aspects.

The aim of the study was to evaluate the use of prostheses, some secondary complications and functional aspects among children who had a congenital leg deficiency or an acquired leg amputation. Rehabilitation physicians were asked to refer children, aged 1-18 years, with a leg deficiency or amputation. Mentally retarded children, children who had only had a toe amputated and children within one year after amputation were excluded. A total of 88 children were included; 64 with a congenital deficiency and 24 with an acquired amputation. In 25 of these 88, both legs were affected; 28 children also had an arm deficiency or amputation. A structured interview was held and the Child-HAQ assessed. Five (5) questions from the Child-HAQ, all relating to leg functions, were analysed. All but 7 children had had a prosthesis fitted, most (89%) using it for almost the entire day. In the children with congenital deficiencies, the first prosthesis had been fitted at an average age of approximately 18 months. Four (4) of the 7 children without prostheses used orthopaedic footwear. The 10 children with congenital deficiencies necessitating prostheses with articulated knees had the first knee of this type fitted at an average age of approximately 37 months. Forty-seven (47) of the 88 children had needed one or more (secondary) operations. In the children with congenital deficiencies, this was usually a conversion procedure, while the children with an acquired amputation had usually been operated on for osseous overgrowth. Twenty (20) of the 88 children experienced or had previously experienced phantom sensations, 5 children phantom pain. Skin problems were common. Most children (95%) were able to walk, most of them (93%) more than 100 m and 93% of the children aged 4 years or over were able to cycle. Most children (94%) aged 6 years or over were able to don and doff their prostheses independently. Some 90% of the children aged 4 years or over attended a normal primary or secondary school. Most (93%) of the children were able to take part in the physical education programme at school, although frequently (47%) with some degree of difficulty. The functional abilities of 88 Dutch children with congenital leg deficiencies or leg amputations were found to be generally satisfactory. Most of the children used prostheses in their daily activities. Secondary complications were, however, frequent.

A study of technical changes to lower limb prostheses after initial fitting.

There is little published material in recent years about the use of lower limb prostheses in an elderly amputee population. In this study the authors were interested in the technical changes to lower limb prostheses after a first limb fitting procedure in a post-rehabilitation population in The Netherlands. The process of fitting a prosthesis and the technical changes to the artificial limb in the first year afterwards are studied.

Ulnar nerve lesions: functional outcome after five years.

OBJECTIVE: To analyse perceived impairments, disability, job restrictions and job changes in subjects with a neurapraxia and neurotmesis of the ulnar nerve five years after trauma. DESIGN: Retrospective, descriptive follow-up study. SETTING: Department of Rehabilitation of a University Hospital. SUBJECTS: Sixteen subjects with a neurotmesis (NT-group) and 20 subjects with a neurapraxia (NP-group) were compared by means of a structured interview assessing perceived impairments and change in job and a questionnaire assessing disabilities (Groningen Activity Restriction Scale: GARS). RESULTS: The NP-group perceived significantly more pain, loss of strength and sensation, loss of dexterity and perceived more job-related restrictions than the NT-group. The NP-group had significantly higher scores on the GARS. There was a moderate correlation between the visual analogue score of the pain and the GARS in the NP- and NT-groups. No significant difference was found between the groups with respect to job changes. CONCLUSIONS: This study shows that subjects with a neurapraxia of the ulnar nerve perceive more impairments and disabilities compared with those subjects with a neurotmesis.

Measurement of severity of sports injuries: an epidemiological study.

OBJECTIVE: To evaluate the severity of sports injuries in relation to the severity of injuries due to other causes and in relation to type of sport, using generally applied measures of injury severity. SUBJECTS: A total of 12403 patients, 4-50 years old, who were treated in the trauma department of the Groningen University Hospital for a sports injury, from January 1990 until January 1997. METHOD: All patients treated because of an injury entered the study. A distinction was made between injuries caused by playing sports, home and leisure accidents, traffic accidents and violence. The severity of the injuries was assessed by using the criteria of rate of admission, Injury Severity Scale (ISS). Finally the sports injuries were analysed with regard to type of sport. RESULTS: In total, 57760 injuries were registered. After injuries due to home and leisure accidents (44%; 25228) sports injuries (21%; 12 403) were the most frequent cause of injury. Of the patients with a sports injury, 7.9% (980) were admitted, which is more than with home and leisure accidents (6.7%; 1690) but less than with traffic accidents (21.5%; 2202) and violence (9.3%; 364). In a majority of cases, admission was related to a limited number of types of sport. The mean ISS of sports injuries was low, as with injuries following home and leisure accidents and violence. The percentage of sports injuries with an ISS higher than or equal to 16 and the percentage mortality were both low in comparison to injuries due to violence or traffic accidents. CONCLUSIONS: Sports injuries rank second highest in terms of cause of injury, after home and leisure accidents; and rank third in terms of severity, after traffic accidents and violence. Even though the ISS is low, sports injuries may have serious consequences.

Diabetic neuropathy examination: a hierarchical scoring system to diagnose distal polyneuropathy in diabetes.

OBJECTIVE: Existing physical examination scoring systems for distal diabetic polyneuropathy (PNP) do not fulfill all of the following criteria: validity, manageability, predictive value, and hierarchy The aim of this study was to adapt the Neuropathy Disability Score (NDS) to diagnose PNP in diabetes so that it fulfills these criteria. RESEARCH DESIGN AND METHODS: A total of 73 patients with diabetes were examined with the NDS. Monofilaments and biothesiometry were used as clinical standards for PNP to modify the NDS. RESULTS: A total of 43 men and 30 women were studied; mean duration of diabetes was 15 years (1-43), and mean age was 57 years (19-90). A total of 24 patients had type 1 diabetes, and 49 patients had type 2 diabetes. Clinically relevant items were selected from the original 35 NDS items (specific item scored positive in >3 patients). The resulting 8-item Diabetic Neuropathy Examination (DNE) score could accurately predict the results of the clinical standards and is strongly hierarchical (H value 0.53). The sensitivity and specificity of the DNE at a cut-off level of 3 to 4 were 0.96 and 0.51 for abnormal monofilament scores, respectively. For abnormal vibration perception threshold scores, these values were 0.97 and 0.59, respectively. Reproducibility as assessed by inter- and intrarater agreement was good. CONCLUSIONS: The DNE is a sensitive and well-validated hierarchical scoring system that is fast and easy to perform in clinical practice.

Dialysate cancer antigen 125 levels in children treated with peritoneal dialysis.

Peritoneal mesothelial cells are important for local host defense and membrane integrity. Dialysate cancer antigen 125 (dCA125) has been shown to be a good marker for the mesothelial cell mass in adult peritoneal dialysis (PD) patients. In children on PD, no information is available yet. We measured dCA125 in 65 dialysate samples from 24 PD children with a median age of 9.2 years (range: 2-18 years) and a median treatment time of 2.6 years (range: 0.1-9.3 years) on PD. The median dCA125 concentration was 8 U/mL (range: 2.3-30.7 U/mL), and the CA125 appearance rate (CA125AR) was 66.5 U/min/1.73 m2 (range: 18-282 U/min/1.73 m2). On cross-sectional analysis, a negative correlation was found between dCA125 and duration of PD treatment (r = -0.3, p = 0.04). No relation was found between age and dCA125 or CA125AR when the first measurement from each child was considered. No correlation was found between dCA125 and the mass transfer area coefficient of creatinine (MTACcreat). Longitudinal analysis showed a negative trend in CA125AR with duration of PD treatment (p = 0.03). No relation was found between peritonitis incidence and dCA125 or CA125AR. In conclusion, no influence of age on dCA125 and CA125AR was found. Levels of dCA125 declined with the duration of PD treatment, reflecting mesothelial cell mass, but they did not correlate with the MTACcreat or the peritonitis incidence in stable PD children.

The Timed "up and go" test: reliability and validity in persons with unilateral lower limb amputation.

OBJECTIVE: To determine the interrater and intrarater reliability and the validity of the Timed "up and go" test as a measure for physical mobility in elderly patients with an amputation of the lower extremity. DESIGN: To test interrater reliability, the test was performed for two observers at different times of the same day in an alternating order. To test intrarater reliability, the patients performed the test for one observer on two consecutive visits with an interval of 2 weeks. To test validity, the results of the Timed "up and go" test were compared with the results on the Sickness Impact Profile, 68-item version (SIP68), and the Groningen Activity Restriction Scale (GARS). PATIENTS: Thirty-two patients, age 60 yrs or older, with unilateral transtibial or transfemoral amputation because of peripheral vascular disease. RESULTS: The Timed "up and go" test showed good intrarater and interrater reliability (r = .93 and .96, respectively). A moderate relationship exists between the Timed "up and go" test and the GARS, a good relationship exists with the "physical subscales" of the SIP68, and there is no relationship with the "mental subscales" of the SIP68. CONCLUSIONS: The Timed "up and go" test is a reliable instrument with adequate concurrent validity to measure the physical mobility of patients with an amputation of the lower extremity.

Time off work due to scaphoid fractures and other carpal injuries in The Netherlands in the period 1990 to 1993.

This study assessed the epidemiology, treatment, disability and time off work due to carpal injuries in the Netherlands in the period from 1990 to 1993. Most injuries were scaphoid fractures and carpal instabilities were rare. The time off work was considerable (mean, 155 days; median, 105 days; range, 12-1708 days). Patients with non-scaphoid fractures had the shortest time off work, followed by those with scaphoid fractures; patients with carpal instabilities had the longest time off work. Despite the significant time off work, the prognosis for return to work was excellent.

Follow up investigation of workers in synthetic fibre plants with humidifier disease and work related asthma.

OBJECTIVE: To investigate the clinical and sociomedical outcome in patients with various clinical manifestations of humidifier disease and work related asthma after removal from further exposure. METHODS: Follow up investigation (range 1-13 years) of respiratory symptoms, spirometry, airway responsiveness, sickness absence, and working situation in patients with (I) humidifier fever (n = 12), (II) obstructive type of humidifier lung (n = 8), (III) restrictive type of humidifier lung (n = 4), and (IV) work related asthma (n = 22). All patients were working at departments in synthetic fibre plants with microbiological exposure from contaminated humidification systems or exposure to small particles (< 1 micron) of oil mist. RESULTS: At follow up patients with work related asthma were less often symptom free (37%, 7/19) than patients with humidifier disease (I, II, III) (67%, 16/24). Mean forced expiratory volume in one second (FEV1) of patients with obstructive impairment had been increased significantly at follow up but still remained below the predicted value. Mean forced vital capacity (FVC) of patients with initially restrictive impairment had returned to normal values at follow up. Airway hyperresponsiveness at diagnosis persisted in patients with obstructive impairment (II + IV 14/17, but disappeared in patients with humidifier fever (3/3) and restrictive type of humidifier lung (2/2). In patients with obstructive impairment (II + IV), FVC and FEV1 at diagnosis were negatively associated with the duration between onset of symptoms and diagnosis and the number of years of exposure. Those with positive pre-employment history of respiratory disease had a lower FEV1 at diagnosis. Sickness absence due to respiratory symptoms decreased in all groups of patients after removal from further exposure, but this was most impressive in patients with the humidifier lung (II, III) and patients with work related asthma (IV). At follow up 83% of the patients were still at work at the same production site, whereas 11% received a disability pension because of respiratory disease. CONCLUSION: In patients with work related respiratory disease caused by exposure from contaminated humidification systems or oil mist, removal from further exposure resulted in clinical improvement, although, especially in those with obstructive impairment, signs persisted. Because of the possibility of transferring patients to exposure-free departments most patients could be kept at work.

Functional outcome of patients with spinal cord injury: rehabilitation outcome study.

OBJECTIVE: To increase our knowledge of neurological recovery and functional outcome of patients with spinal cord injuries in order to make more successful rehabilitation programmes based on realistic goals. DESIGN: Descriptive analysis of data gathered in an information system. SETTING: Rehabilitation centre in The Netherlands with special department for patients with spinal cord injuries. SUBJECTS: Fifty-five patients with traumatic spinal cord lesions admitted to the rehabilitation centre from 1988 to 1994. MAIN OUTCOME MEASURES: The functional improvement was presented in terms of progress in independence in nine daily activity skills. Independence was rated on a four-point scale. RESULTS: From admission to discharge, lesions in 100% of patients with tetraplegia and 96% of patients with paraplegia remained complete. Significant progress in independence was made in self-care, ambulation and bladder and bowel care. Differences were found in the extent of functional improvement between subgroups of patients with different levels and extent of lesion. Contrary to expectations based on theoretical models, patients with complete paraplegia did not achieve maximal independence in self-care. Independent walking was only attained by patients with incomplete lesions. Regarding outcome of bladder and bowel care, poor results were found, especially the independence in defaecation and toilet transfers. CONCLUSIONS: The results of this study provided more insight into the functional outcome of a group of patients with traumatic spinal cord injury. More research is needed to evaluate the rehabilitation programmes for these patients.

[Consideration of mental symptoms and physical disabilities in deciding upon placement in a residential home versus a nursing home].

This study analysed 235 applications of elderly people for residential home and nursing home care. The applications were submitted to a Dutch municipal care allocation board. Based on the 1994 registration data from this board the impact of physical restrictions and mental problems on the care allocation for residential or nursing homes and connected care was studied. Physical complaints were measured with an adl and an hdl scale (Activities of Daily Living and Household Activities of Daily Living), mental problems were assessed by means of the Reality, Orientation and Restlessness Scales. Persons with an admission allocation for a nursing home (both psychogeriatric and somatic) had the highest scores on all scales; persons allocated to the residential home and related care had significantly lower scores. Above-mentioned scales have been combined into care level categories. Fifty seven persons, however, appeared not to have any physical or mental problems despite a care allocation to the residential home or related care. Contextual problems (housing, social contacts, endurance-capacity of relatives and friends) were particularly decisive in this case. Moderately severe problems, both physical and mental, generally resulted in an allocation to the residential home or related care. Serious problems usually result in allocation to the somatic or the psychogeriatric nursing home. Combined serious problems (75%) tended to result in an allocation to the psychogeriatric nursing home. This study is preliminary to the development of a care allocating instrument.

Long-term physical, psychological and social consequences of a fracture of the ankle.

The long-term physical, psychological and social outcomes of 68 patients with an ankle fracture were investigated by using a postal questionnaire 6 years after injury. Patients were treated at a level I Trauma Centre between January 1989 and December 1989. Where applicable, the outcomes were compared with the outcomes of severely injured patients who were investigated previously. Physically, the patients were suffering from problems in the extremities and the spine. Surprisingly, half of them (52 per cent) had psychological complaints due to the initial injury. Eighty-nine per cent of the patients returned to work. This result seems to be only slightly better than the return to work in severely injured patients (74 per cent). Those with an ankle fracture needed less time to return to work (3 months versus 13 months in the severely injured patients). Further social changes (marital status, leisure activities) were mostly found in the severely injured patients. Patients with an ankle fracture as well as severely injured patients are affected by long-term consequences. The differences between the two groups are not as pronounced as is generally assumed. Probably, the consequences of lesser injuries are frequently disregarded, whereas severely injured patients are doing better than expected.

Long-term physical, psychological and social consequences of severe injuries.

This 6 year follow-up study was designed to evaluate the long-term physical, psychological and social outcomes of severely injured patients (Injury Severity Score of greater than or equal to 16). Patients were treated at the University Hospital Groningen, the Netherlands, between January 1989 and December 1989. Outcomes were assessed using a postal questionnaire. After injury, the 55 respondents had predominantly complaints of the extremities, the spine and the head. Psychological complaints were present in 84 per cent of patients and mainly concerned fatigue, slowness and memory impairments. Despite these physical and psychological complaints, 74 per cent of patients were able to return to work and the memory succeeded in complying with job requirements. Injuries of the extremities and the spine were risk factors for failing to return to work. Social consequences were also reflected in broken marriages (6/22) and changes of leisure activities (45 per cent). On the basis of the impairments and disabilities revealed, we conclude that further improvement of the long-term outcomes of severely injured patients may be achieved by advancements in the treatment of injuries to the head, spine or extremities, comprehensive psychological support and vocational rehabilitation.

Socio-economic differences in health risk behavior in adolescence: do they exist?

Socio-economic differences in risk behaviors in adolescence can be seen as a prelude to the re-emergence of socio economic health differences in adulthood. We studied whether or not socio-economic differences in health risk behaviors are present in male and female adolescents in The Netherlands. The relation between socio-economic status (SES) and health risk behaviors was examined, by testing both the main and interaction effects of SES and gender on separate health risk behaviors on one hand, and on the behaviors cumulatively on the other. The data were derived from 1984 adolescents in the four northern provinces of The Netherlands. SES was measured by means of the educational level and the occupational status of both parents. Four health risk behaviors were included in this study: smoking, alcohol consumption, soft drug use, and (no) physical exercise. We found that the relationships between SES and health risk behaviors are not as linear as is often found in adulthood. Our findings can be characterised overall by an absence of relationship between SES and health risk behaviors. The only exception applies to sport, which is linearly related to SES. Adolescents in the lower SES groups engage in sport less than adolescents in the higher SES groups. There was an irregular relationship between the father's occupational status and the adolescents' smoking and drinking. Adolescents in the highest, lowest and middle of the six SES groups have the highest rates of health risk behaviors. All observed relationships are similar for both male and female adolescents. A relationship between gender and the separate health risk behaviors was found only for alcohol consumption and drug use. For both male adolescents showed higher rates of risk behavior. Males also scored higher on the cumulative health risk behaviors than their female counterparts. The findings of this study do not support the hypothesis of latent differences in adolescence.

Bone mineral density, bone metabolism and body composition of children with chronic renal failure, with and without growth hormone treatment.

OBJECTIVE: Osteopenia has been reported in adult patients with chronic renal failure (CRF). Only a few studies have been performed in children. The objective of this study was to evaluate bone mineral density (BMD), bone turnover, body composition in children with CRF and to study the effect of GH on these variables. DESIGN: Two groups were identified: patients with growth retardation who received GH (GH-group) and patients most of whom were not growth retarded who did not receive GH (no-GH-group). After an observation period of 6 months, the patients in the GH-group started GH treatment. Patients were studied every 6 months during 18 months. PATIENTS: Thirty-six prepubertal patients (27 boys and 9 girls), mean age 7.9 years, with CRF participated in the study. The GH-group consisted of 17 patients of whom 14 completed one year treatment. The no-GH-group consisted of 19 patients, of whom 16 were followed for 6 months, 14 for 12 months and 13 for 18 months. MEASUREMENTS: Lumbar spine BMD, total body BMD and body composition were assessed by dual energy X-ray absorptiometry, compared to age-and sex-matched reference values of the same population and expressed as standard deviation scores (SDS). BMD of appendicular bone was measured by quantitative microdensitometry (QMD). Blood samples were obtained to assess bone metabolism and growth factors. RESULTS: Baseline mean lumbar spine and total body BMD SDS of all patients were not significantly different from normal. Mean lumbar spine and total body BMD SDS did not change significantly in the GH-group during GH treatment. The change of QMD at the midshaft during the first 6 months of GH treatment was significantly smaller than during the observation period (P < 0.01). Height SDS and biochemical markers of both bone formation and bone resorption increased significantly during GH treatment; 1,25-dihydroxyvitamin D remained stable. Lean tissue mass increased (P < 0.001) and percentage body fat decreased (P < 0.01) during GH treatment. BMD, the biochemical markers of bone turnover which are independent of renal function, and body composition remained stable in the no-GH-group. CONCLUSIONS: Mean lumbar spine and total body BMD of children with chronic renal failure did not differ from healthy controls. The lack of a GH-induced increase in 1,25-dihydroxyvitamin D levels, probably due to treatment with alpha-calcidol, might be linked to the absence of a response in BMD during GH treatment in children with chronic renal failure.

Variation in measurements of grip strength. A study in reflex sympathetic dystrophy patients.

The clinical picture of reflex sympathetic dystrophy (RSD) is characterized by a combination of the triad: autonomic, motor and sensory changes. In this study, the grip strength is measured in 29 upper extremity RSD patients. We used the generalizability theory to assess the extent of the disagreement or differences (errors in measurement) within or between observers and interactions between observer-session and repetition of the measurements. The aims of our study were to determine the different sources of variation in grip strength tests and the smallest detectable differences (SDD) as well as the reliability of upper extremity grip strength tests in RSD patients. The main sources of variation of measurement errors were observer, patient/observer interactions and patient/session/observer interaction and a random source. We found that the generalizability theory is useful for estimating the sources of measurement error. Clinical examinations for muscle strength measurements, as a part of a total clinical examination, for example for a disability payment or worker's compensation in case of RSD patients should be done by more than one observer in more than one session and more than once.

The role of renal scintigraphy in the diagnosis and follow-up of unilateral ATN after complete bilateral distal ureteral obstruction as a complication of acute appendicitis.

Acute anuria due to bilateral distal ureteral obstruction developed in two boys, ages 7 and 13, several days after appendectomy, without sonographic signs of hydronephrosis or hydroureters. Decompression was achieved after introduction of ureteric stents. This failed on the left side in one patient, and unilateral acute tubular necrosis (ATN) subsequently developed on that side. Although bilateral decompression was successful in the second patient, ATN had already developed on the left side. In both patients, Tc-99m MAG3 renal scintigraphy proved to be an important tool in diagnosing unilateral ATN and for evaluating the recovery from this rare complication.
