Previous research has indicated that postoperative distress is influenced by diverse biographic, medical and psychological variables, such as personality, coping behaviours and anxiety. The influence of state variables, apart from anxiety and coping behaviour, has received scant attention. Furthermore, the influence of coping behaviour has remained unclear. The present study investigated coping behaviour and indications of physical distress, i.e., preoperative fatigue, leg pain and back pain, besides preoperative anxiety, as predictors of postoperative anxiety and physical complaints in 126 patients undergoing lumbar surgery. Preoperative anxiety and leg pain independently predicted more postoperative anxiety beyond the influence of age, sex and medical variables. Preoperative anxiety and fatigue independently predicted more postoperative physical complaints. No associations were found between the coping behaviours and the postoperative variables. The implications of these results are discussed in relation to intervention strategies aimed at diminishing the stress of surgery.

Fracture of the tibia is a well-known, often occult cause of limping and leg pain in young children. This fracture is typically a hairline, oblique fracture of the shaft of the tibia, and in some cases the fracture can be so subtle that bone scintigraphy or follow-up radiography may be required for its detection. In addition, a variety of other fractures that are less well known and just as difficult to detect can occur in the tibia and the foot in young children. These fractures include plastic bowing and buckle-type fractures, especially of the fibula; impaction, compression, or stress (fatigue) fractures of the tibia and fibula; and fractures of the metatarsal and tarsal bones. All of these fractures can be remarkably similar to the non-displaced spiral tibial fracture in their clinical appearance and should be included under the rubric of "toddler's fracture."

Childhood sarcoidosis is a disease with multisystem organ involvement, and initial presentation as fever of unknown origin (FUO) is relatively common. We describe herein three children (aged 9, 7, and 11 years) with sarcoidosis who were seen initially with FUO. Common clinical and laboratory features include fever of > 2 weeks' duration, weight loss, fatigue, leg pain, anemia, increased erythrocyte sedimentation rate, elevated immunoglobulin G level, negative antinuclear antibodies and rheumatoid factor, and negative purified protein derivative and Candida skin tests. Two patients had iridocyclitis, one had hilar adenopathy, and two had angiotensin-converting enzyme serum levels. All three had no evidence of pulmonary infiltrates on chest radiographs. Bone marrow biopsies for all three were normal, and with no evidence of malignancy. Plain radiographs of the lower extremities and bone scan were normal. Magnetic resonance imaging (MRI) of the lower extremities revealed intact bone architecture and multifocal nodular lesions within the marrow. Bone biopsy from the tibia performed on two patients showed normal bone trabeculae and a solitary noncaseating epithelioid cell granuloma. Noncaseating granuloma was found on reevaluation of the bone marrow biopsy in the third patient. All three patients had negative marrow stains and cultures for fungi and mycobacteria. We conclude that MRI was very useful in the diagnosis of sarcoidosis in children with FUO.

The aim of this study was to evaluate the results of surgical treatment of coarctation of the aorta. All patient files on patients operated at Haukeland Hospital, Bergen, Norway, in the period 1975-95 (n = 102) were surveyed. We sent a questionnaire to all patients alive in 1996 (n = 84), and 82 (98%) responded. Six patients (6%) died within 30 days of surgery, and 12 (12%) died later. These mortality numbers were smaller among patients operated in the period 1988-95. Among patients with associated heart defects (n = 28) the numbers were 14% and 25%, respectively. Four patients required reoperation and three patients balloon dilatation. Six of these patients were operated in the period 1975-87. Among the 82 patients that responded to the questionnaire, clinical follow-up by a cardiologist had been discontinued in 35 cases. 31 patients (38%) were not satisfied with the follow-up. Many patients reported muscle fatigue in the legs (30%), reduced exercise performance (29%), headache (26%), general fatigue (22%), and leg pain (17%). 38% did not report any symptoms. Our results are in accordance with previously reported studies, and the mortality numbers were reduced in the second period. The number of recurrences was also reduced in this period. The symptoms reported by many patients may be caused by recoarctation or an abnormal blood pressure. This group of patients should, therefore, be monitored systematically for abnormal blood pressure, recoarctation and aortic valve disease.

Progressive diaphyseal dysplasia (PDD), a rare disorder of bones, in recent years has been accepted as a systemic disease within the spectrum of connective tissue disorders associated with immunological abnormalities. Steroids have been used in the treatment of PDD with variable success. In this report PDD is described in a 5-year-old boy who presented with leg pain, fatigue, headache and anorexia with an onset in infancy. Physical examination revealed a waddling gait, thorax deformity and thickening in the upper extremities. The diagnosis was made by radiologic demonstration of cortical thickening and a narrowed medullary cavity of the long bones of extremities. Bone scintigraphy showed areas of increased osteoblastic activity in the diaphyseal part of the long bones of extremities and the skull. Electron microscopic examination revealed myopathic and vascular changes. Serum immunoglobulin A, G and M levels were elevated and CD4 positive T cell numbers were low. Deflazacort, a steroid with a similar anti-inflammatory effect to prednisolone but with fewer adverse effects, was started in a dose of 1.2 mg/kg/day. Deflazacort treatment resulted in clinical and radiological improvement within 12 months with no side effects. In conclusion, steroids may be recommended as an effective method of treatment in PDD and deflazacort may be a safe alternative steroid.

We described longitudinal changes of movement performance in a population-based sample of women followed from age 70 to 78. We also studied the cross-sectional relationships between medical conditions and movement performance at baseline, and longitudinal relationships between baseline medical conditions and changes of movement performance. Two hundred and thirty-four women aged 70 years participated in the baseline study, and 88 women participated in a follow-up study 8 years later. Movement performance was measured by an optoelectronic test, the postural-locomotor-manual (PLM) test, which objectively and precisely measures the subject's mobility of lower and upper extremities. Information on medical conditions including selected diseases and symptoms were obtained by self-report and/or by physical examination. Movement time (MT), an indicator of the overall movement performance of the PLM test, increased over 8 years. This change was mainly related to prolonged duration of the locomotor phase (walking forward), but not to the duration of the manual phase (goal-directed arm reaching). At baseline, poor PLM performance was related to hypertension, orthostatic hypotension, cerebrovascular diseases, chronic bronchitis, depression, arthritis, dizziness, chest pain, dyspnea, joint problems, leg pain, tiredness, number of diseases and number of symptoms at baseline. Increased MT during follow-up was associated with arthritis and dyspnea at baseline, and newly developed diseases during follow-up. Our study results indicated that 70-year-old women had a general slowing of their movement performance over 8 years. Age-related decrements of movement performance were more striking in the lower extremities than in the upper extremities. Arthritis and dyspnea at baseline, and incident diseases during follow-up were related to this age-related decline of movement performance.

We report a collegiate field hockey player who sustained a sacral fatigue-type stress fracture that manifested as persistent low back and leg pain. The diagnosis of sacral stress fracture was suggested by history and physical examination and confirmed by magnetic resonance imaging. Our patient experienced complete resolution of symptoms after a 3-mo interval of activity restriction. This article describes the first reported case of a sacral stress fracture in a field hockey player.

McArdle's disease is a rare, inherited deficiency of myophosphorylase, an enzyme required for the utilization of glycogen. Patients with myophosphorylase deficiency classically present with exercise intolerance, leg pain and muscle fatigue. The case of a young woman with exertional dyspnea and leg cramps is described. Exercise testing confirmed the presence of exercise intolerance and demonstrated an accelerated heart rate response, despite the absence of an anaerobic threshold and a respiratory exchange ratio of less than 1.0. Subsequent ischemic forearm testing and muscle biopsy confirmed the diagnosis of myophosphorylase deficiency. Evaluation of lung mechanics with esophageal pressure measurements demonstrated the presence of respiratory muscle weakness and early fatiguability, suggesting that the patient's dyspnea might have been attributable to an increased respiratory effort. Dyspnea is not a classic symptom associated with myophosphorylase deficiency, although subclinical respiratory muscle impairment may be present. No previous studies have evaluated respiratory muscle function during exercise in patients with myophosphorylase deficiency.

The syndrome of chronic heart failure (CHF) becomes increasingly prevalent in older patients, and while mortality rates are declining in most cardiovascular diseases, both prevalence and mortality in CHF remain high. The heart is unable to meet the demands of the skeletal musculature, and symptoms manifest as dyspnoea and signs of fatigue during exercise. The cardiopulmonary exercise test (CPET) can provoke symptoms which may be useful in improving the accuracy of diagnosis in CHF in a non-invasive setting. CPET also provides important information on the pathophysiology of exercise limitation, risk stratification and can establish exercise-training protocols. The information provided by the CPET allows suitable pharmacological or device-based adjustments to be considered in the management of CHF, which can be crucial in maintaining a patient's quality of life. This manuscript provides a useful insight into the theoretical rationale and practical recommendations for CPET in patients with CHF. Prior to CPET, it is important to consider the mode of exercise, as cycle ergometry or treadmill protocols will yield different outcomes in patients with CHF. We discuss how pre-CPET set-up procedures should be conducted and also the significance of electrocardiographic abnormalities found in CHF patients, and how these should be interpreted. The assessment of lung function is integral to the underlying pathophysiological basis of exercise limitation and we explain how this should be performed. CHF patients display the following abnormal exercise responses which can be identified by CPET: peak oxygen uptake ( [Formula: see text] peak), anaerobic threshold (AT), DeltaVO(2)/Delta work rate (WR), peak oxygen pulse, estimated peak stroke volume and predicted peak heart rate are reduced. The [Formula: see text] slope is abnormally high and the breathing reserve is normal or high. An immediate post-exercise increase in O(2) pulse is evident, and/or a regular oscillatory breathing pattern has been observed at lower exercise intensities in some CHF patients. Symptoms of breathlessness, fatigue, and/or leg pain occur earlier during CPET and may cause the CPET to be aborted early. We explain the significance of the 9-panelled array, and how it can help to determine the underlying pathophysiology of exercise intolerance in these patients.

We performed a multicenter survey using a semistructured interview in 1,072 consecutive patients with Parkinson's disease (PD) enrolled during 12 months in 55 Italian centers to assess the prevalence of nonmotor symptoms (NMSs), their association with cognitive impairment, and the impact on patients' quality of life (QoL). We found that 98.6% of patients with PD reported the presence of NMSs. The most common were as follows: fatigue (58%), anxiety (56%), leg pain (38%), insomnia (37%), urgency and nocturia (35%), drooling of saliva and difficulties in maintaining concentration (31%). The mean number of NMS per patient was 7.8 (range, 0-32). NMS in the psychiatric domain were the most frequent (67%). Frequency of NMS increased along with the disease duration and severity. Patients with cognitive impairment reported more frequently apathy, attention/memory deficit, and psychiatric symptoms. Apathy was the symptom associated with worse PDQ-39 score but also presence of fatigue, attention/memory, and psychiatric symptoms had a negative impact on QoL. These findings further support a key role for NMS in the clinical frame of PD and the need to address them specifically in clinical trials using dedicated scales.
