Improved detection of cardiac contusion with cardiac troponin I.

Detecting cardiac injury in patients with chest trauma is difficult because the level of the MB isoenzyme of creatine kinase (MBCK) can be elevated from skeletal muscle injury alone. However, the level of cardiac troponin I (cTnl) is not elevated by skeletal muscle injury. To determine whether its measurement would improve the ability to detect cardiac injury in patients with blunt chest trauma, 44 patients were studied. Serial echocardiograms and serial blood samples were obtained. Six patients had evidence of cardiac injury by echocardiography; all had elevations of MBCK and cTnl. One patient had elevations of both MBCK and cTnl with only a pericardial effusion. Twenty-six of the 37 patients without contusion had elevations of MBCK; none had elevations of cTnl. The ratio of MBCK to total creatine kinase improved specificity at the expense of sensitivity. Measurement of cTnl accurately detects cardiac injury in patients with blunt chest trauma and should facilitate the diagnosis and management of such patients.

Body composition in growth hormone deficient adults over the age of 60 years.

OBJECTIVE: Elderly patients with hypothalamic-pituitary disease exhibit a reduction in GH secretion distinct from the decline in GH secretion related to age. GH deficiency in young adults causes a change in body composition, with increased fat mass (FM) and reduced fat free mass (FFM), similar to that seen as a result of the normal ageing process. The aim of this study was to determine whether organic GH deficiency in elderly patients may cause changes in body composition beyond those due to ageing. SUBJECTS: Twenty-one patients (15 male) with documented pituitary disease and 24 controls (17 male) matched for age, height, weight and BMI, all over the age of 60, in whom GH status had been defined by a 24-hour GH profile and an arginine stimulation test. MEASUREMENTS: Serum was taken for fasting IGF-l and IGFBP-1 estimations. Total and regional FM and FFM were determined using dual-energy X-ray absorptiometry. RESULTS: FM (median (range)) was increased in the patients, 27.76 (19.25-50.24) vs 21.23 (8.81-49.15) kg in the controls (P < 0.005). FM was significantly increased in the arms, legs and trunk in the patients compared with the controls. The proportion of fat deposited centrally did not differ significantly between the two groups (57.0% (47.6-65.1) in the patients vs 55.3% (44.1-63.8) in the controls, P = 0.25). There was an inverse relation between total FM and serum IGFBP-1 present in the patients, p = -0.632, P < 0.005, and in the controls p = -0.467, P < 0.05, but the relation between total FM and area under the GH profile was significant only in the controls (p = -0.651, P < 0.001) and not in the patients. FFM (51.19 (26.96-69.18) kg in the patients vs 51.55 (32.35-60.53) kg in the controls, P = 0.99) and serum IGFBP-1 levels did not differ significantly between the two groups. CONCLUSION: Organic growth hormone deficiency causes changes in body composition beyond the changes associated with the ageing process. These changes differ from those seen in younger GH deficient adults in that they are limited to an increase in FM with no change in FFM. These findings indicate that even in the elderly, in whom GH secretion is normally very low, the additional imposition of GH deficiency due to organic disease has significant biological impact.

Mobility status and bone density in cerebral palsy.

The spinal bone mineral density (SBMD) and calcaneal broadband ultrasound attenuation (BUA) was measured in 27 children with cerebral palsy. They were categorised into four mobility groups: mobile with an abnormal gait, mobile with assistance, non-mobile but weight bearing, non-mobile or weight bearing. Mean SD scores for BUA and SBMD differed among mobility groups (analysis of variance, p < 0.001 and p = 0.078, respectively).

Risk factors, falls, and fracture of the distal forearm in Manchester, UK.

OBJECTIVE: To determine the risk factors associated with fracture of the distal forearm, and to evaluate the influence of falls on these risks. DESIGN: This was a case-control study. SETTING: Manchester, UK. PARTICIPANTS: The cases were 62 white women aged 45-82 years who had sustained a fracture of the distal forearm and had attended local hospitals. Two control groups were studied - 50 women who had fallen onto the hand but had not sustained a fracture (recruited from the same source as those with fracture) and 116 women randomly selected from primary care age and sex registers in the catchment area of the hospitals. Both cases and controls were sent a letter inviting them to take part in the study. Data were collected by questionnaire completed by an interviewer. MAIN RESULTS: Compared with the population control group, those with fracture were more likely to walk at a brisk pace (odds ratio (OR) = 3.5; 95% confidence interval (CI) 1.3, 9.6) though they had undertaken less physical activity at home or work on a daily basis throughout life (OR = 0.4; 95% CI 0.2, 0.9). The risk associated with brisk walking was less marked when the cases were compared with fall controls. Other lifestyle factors including calcium intake, smoking, and alcohol consumption were not associated with fracture. Analysis of gynaecological and hormonal factors suggested that compared with population controls, those with fracture of the distal forearm had had fewer fertile years (OR = 0.4; 95% CI 0.1, 0.9) and were less likely to have used oral contraceptives (OR = 0.3; 95% CI 0.1, 0.9). CONCLUSIONS: The data highlight the need for caution when advising middle aged and elderly subjects about exercise. Such advice should be combined with practical information about the prevention of falls. Hormonal factors seem to be additional determinants of fracture. Other lifestyle interventions seem unlikely to play an important part in preventing distal forearm fracture.

Mandibular bone mineral density as a predictor of skeletal osteoporosis.

A considerable amount of work has been performed on methods of detecting individuals with low bone mass at an early stage. Some researchers have considered if dental radiographs could have a role in the detection of individuals with osteoporosis. A basic requirement for this would be that bone mass in the jaw relates significantly to that of other skeletal sites in which osteoporosis is a significant problem. The first aim of this study was to investigate the relationship between mandibular bone mineral density (BMD) and that of other skeletal sites commonly used for bone densitometry in the detection of osteoporosis. The second aim was to assess the validity of mandibular BMD as a predictor of BMD in these other sites. 40 edentulous females underwent dual energy X-ray absorptiometry (DXA) of the lumbar spine (L2-L4), DXA of the right femoral neck, single photon absorptiometry (SPA) of the proximal and distal forearm and DXA of the mandible. Significant correlations were observed between BMD in the mandibular body, ramus and symphysis and all other skeletal sites (p < 0.02). Five patients (12.5%) had age matched Z-scores of -1.0 or lower in all three non-mandibular sites (lumbar spine, femoral neck and forearm). Using these patients as the proportion of the population with a positive finding of "low bone mass", the sensitivity and specificity of mandibular BMD in predicting low bone mass for these patients was determined. Where a diagnostic threshold for low mandibular BMD was set at one standard deviation below the mean, the mandibular body BMD measurement gave high sensitivity (0.8) and specificity (0.97), the symphysis BMD low sensitivity (0.4) but a high specificity (0.77), while the ramus BMD had a moderate level of sensitivity (0.6) and high specificity (0.91). It is concluded that mandibular BMD assessed by DXA correlates significantly with BMD measurements of other important skeletal sites. The higher correlation coefficients and the greater sensitivity and specificity for the body of mandible suggest that this site should be used for any potential clinical application of dental radiographs in detection of osteoporosis.

Further increase in forearm cortical bone mineral content after discontinuation of growth hormone replacement.

OBJECTIVE: Growth hormone replacement of adults with childhood onset GH deficiency results in an increase in bone mineral density (BMD) after 6-12 months of GH replacement. By measuring BMD 12 months after discontinuation of GH replacement we aimed to investigate whether there is an effect of GH replacement on BMD persisting after GH has been withdrawn. DESIGN: BMD was measured 13 +/- 1 (mean +/- SE, range 11-16) months after discontinuation of GH replacement. PATIENTS: Ten adults, age 23.2 +/- 1.4 (range 18.8-32.4) years, with childhood onset isolated GH deficiency (2 idiopathic, 8 irradiation induced) who had previously completed a study of the effect of 12 months of GH replacement on BMD. MEASUREMENTS: Forearm cortical bone mineral content (BMC) was measured using single-photon absorptiometry at the proximal site of the distal forearm. Forearm integral BMC at the ultradistal site of the forearm and bone width at both proximal and ultradistal sites of the distal forearm were measured by the same technique. Vertebral trabecular BMD was measured using quantitative computed tomography. RESULTS: Forearm cortical BMC was significantly greater than that measured at the time of discontinuation of GH (1.48 +/- 0.04 vs 1.44 +/- 0.05 g/cm). There was no significant change in forearm integral BMC or in vertebral trabecular BMD after discontinuation of GH. There was no significant change in bone width at proximal and ultradistal sites of the distal forearm after discontinuation of GH. CONCLUSION: After discontinuation of GH replacement the further increase in forearm cortical bone mineral content without a significant increase in forearm bone width suggests that the increase in cortical bone mineral content is due to a persisting effect of previous GH replacement, and not to further spontaneous attainment of bone mass before peak bone mass is reached. These findings emphasize the importance of continuing to monitor bone mass after the stimulus to increase bone turnover has been withdrawn.

Effect of growth hormone replacement on bone mass in adults with adult onset growth hormone deficiency.

OBJECTIVE: Previous studies of the effect of GH replacement on bone mass in adults with GH deficiency have produced conflicting results. We have studied the effect of 6 and 12 months of GH replacement on bone mass in adults with adult onset GH deficiency. DESIGN: Double blind placebo controlled study of GH replacement (0.125 IU/kg/week for the first month and 0.25 IU/kg/week thereafter) for 6 months and an open study for a further 6 or 12 months. PATIENTS: Twenty-two adults (10 men, 12 women), aged 41.5 +/- 2.1 years (mean +/- SE, range 23.6-59.5), with adult onset GH deficiency. MEASUREMENTS: Single-energy quantitative computed tomography was used to measure vertebral trabecular bone mineral density (BMD), single-photon absorptiometry (SPA) was used to measure forearm cortical and integral bone mineral content and BMD and dual-energy X-ray absorptiometry (DXA) was used to measure lumbar spine, femoral neck, trochanteric and Ward's triangle integral BMD. RESULTS: After 6 months of GH replacement (n = 21) there was a significant decrease in forearm cortical BMD (SPA: median change -0.009 g/cm2, P = 0.01), forearm integral BMD (SPA: median change -0.016 g/cm2, P = 0.03), lumbar spine BMD (DXA: median change -0.22 g/cm2; P = 0.003) and femoral neck BMD (DXA: median change -0.029 g/cm2, P = 0.006). After 12 months of GH replacement (n = 13) there was a significant decrease in lumbar spine BMD (DXA: median change -0.035 g/cm2, P = 0.002) from baseline. There was no significant increase in bone mass at any site after 6 or 12 months of GH replacement. Change in bone mass was not influenced by sex of the patient or by presence or absence of additional pituitary hormone deficiencies. CONCLUSION: The response of bone mass to 6 and 12 months of GH replacement in adults with adult onset GH deficiency is disappointing. Longer-term studies are required to determine whether prolonged GH replacement has a beneficial effect on bone mass.

Osteopenia, neurological dysfunction, and the development of Charcot neuroarthropathy.

OBJECTIVE: To determine factors that might be associated with the development of Charcot neuroarthropathy. RESEARCH DESIGN AND METHODS: This cross-sectional prevalence study examined neurological function and bone density in matched groups of neuropathic diabetic patients with and without radiological evidence of Charcot neuroarthropathy. RESULTS: Patients with Charcot neuroarthropathy had a global impairment of neurological function that was significantly greater than that of otherwise matched non-Charcot neuropathic patients. All 17 Charcot patients had evidence of autonomic neuropathy compared with 10 of the control subjects (P = 0.03). The Charcot patients had evidence of reduced bone density in the lower limbs compared with the neuropathic control subjects (P = 0.009), but relatively preserved bone density in the spine (P = 0.4 vs. control subjects). CONCLUSIONS: We conclude that minor trauma in diabetic patients with peripheral neuropathy might result in a fracture in those with a reduced bone density and thus trigger the development of Charcot neuroarthropathy.

Diagnosis of perioperative myocardial infarction with measurement of cardiac troponin I.

BACKGROUND: Perioperative myocardial infarction is the most common cause of morbidity and mortality in patients who have had noncardiac surgery, but its diagnosis can be difficult. The present study was designed to determine whether the measurement of serum levels of cardiac troponin I, a highly sensitive and specific marker for cardiac injury, would help establish the diagnosis of myocardial infarction. METHODS: We obtained preoperative measurements of MB creatine kinase, total creatine kinase, and cardiac troponin I, in addition to base-line electrocardiograms and two-dimensional echocardiograms, in 96 patients undergoing vascular surgery and 12 undergoing spinal surgery. Blood samples were obtained every 6 hours for at least the first 36 hours after surgery, and electrocardiograms were obtained daily; a second echocardiogram was obtained approximately three days after surgery. The appearance of a new abnormality in segmental-wall motion on the postoperative echocardiogram (that is, an abnormality that had not been seen on the preoperative echocardiogram) was considered to be indicative of perioperative infarction. RESULTS: Eight patients who underwent vascular surgery had new abnormalities in segmental-wall motion and received a diagnosis of perioperative infarction. All eight had elevations of cardiac troponin I, and six had elevations of MB creatine kinase. Of the 100 patients without perioperative infarction detected by echocardiography, 19 had elevations of MB creatine kinase, and 1 had a slight elevation of cardiac troponin I. CONCLUSIONS: The measurement of cardiac troponin I is a sensitive and specific method for the diagnosis of perioperative myocardial infarction. It avoids the high incidence of false diagnoses associated with the use of MB creatine kinase as a diagnostic marker.

Reproductive performance of dairy cows following treatment with fenprostalene, dinoprost, or cloprostenol between 24 and 31 Days post partum: a field trial.

Three hundred and one Holstein cows (n=301), calving at a commercial free-stall dairy farm, were randomly assigned to 1 of 3 prostaglandin treatment groups or a placebo group. The placebos were packaged 3 ways to mimic the 3 commercial prostaglandin preparations. Group 1 received 1 mg fenprostalene and 1.6 mg oxytetracycline; Group 2 received the fenprostalene placebo (2 ml polyethylene glycol and 1.6 mg oxytetracycline); while Group 3 was given 25 mg dinoprost. Group 4, the dinoprost placebo received 5 ml saline; Group 5 received 500 microg cloprostenol; and Group 6 the cloprostenol placebo received 2 ml saline. The treatments were administered between Days 24 and 31 post partum. Double blind techniques were used in administering treatments and in assessing the response to treatment. There were no significant differences among treatment groups with respect to incidence of retained fetal membranes, endometritis, pyometra, anestrus, number of services per pregnancy, calving-to-first estrus interval, services per conception, number of prostaglandin treatments other than those administered between Days 24 and 31 post partum, the percentage culled for reproductive reasons and all factors combined. Cows receiving fenprostalene, dinoprost or cloprostenol had a decreased calving-to-conception interval compared with that of the controls (P = 0.05). It is concluded that, in the herd studied, treatment with any of the 3 commercially available prostaglandin products between Days 24 and 31 post partum was beneficial for reproductive performance.

European semi-anthropomorphic phantom for the cross-calibration of peripheral bone densitometers: assessment of precision accuracy and stability.

A semi-anthropomorphic 'distal radius like' phantom, developed by Kalender and Ruegsegger for use in peripheral bone densitometry using single photon (DPA) dual X-ray (DXA) and quantitative computed tomography (QCT) machines, has been studied with a view to cross-calibrating different types and brands of densitometers in current use. In the context of an EU 'Concerted Action' (second Framework Programme) the phantom was repeatedly measured on six SPA machines, three DXA machines and nine QCT machines (545 measurements). Linear regression equations were derived, individual to each machine, which allowed the derivation of 'standardized densities'. In this way we converted measurements made by machines of the same modality to a common scale of measurements. Two machines (one DXA, one SPA) showed statistically significant instability over time emphasising the need for rigorous quality control in the application of densitometry. In other respects these results provide an encouraging basis for the derivation of standardized normative ranges and the more effective use of peripheral densitometry in future clinical and epidemiological studies.

Reduced bone mineral density in men following chemotherapy for Hodgkin's disease.

We have measured bone mineral density (BMD) in 29 men, mean age 35.0 (range 19.7-58.0) years, with testicular damage following MVPP or hybrid chemotherapy for Hodgkin's disease. Forearm cortical bone mineral content (BMC) and lumbar spine and femoral neck integral BMD were measured 3.4 (1.1-6.8) years after completion of chemotherapy, and results expressed as Z (standard deviation) scores. There was a significant reduction in forearm cortical BMC (median BMC 1.727 g cm-1, median Z-score -0.8, P < 0.0005), in lumbar spine integral BMD (median BMD 1.141 g cm-2, median Z-score -0.6, P < 0.0005) and in femoral neck integral BMD (median BMD 0.991 g cm-2, median Z-score -0.4, P < 0.05). There was no significant correlation between Z-score and time elapsed since completion of chemotherapy, and no significant difference in Z-score according to type of chemotherapeutic regimen or number of cycles of chemotherapy received. In conclusion, men who are in complete remission following treatment of Hodgkin's disease have reduced cortical and trabecular BMD. Possible causes include mild hypogonadism secondary to chemotherapy-induced impairment of Leydig cell function, a direct effect of chemotherapy on bone, an effect of high-dose glucocorticoid on bone or an effect of Hodgkin's disease per se.

Histological, radiological, and biochemical features of the adynamic bone lesion in continuous ambulatory peritoneal dialysis patients.

Adynamic bone is being found with increasing frequency in dialysis patients. Little is known about its aetiology, and even less about its natural history. We found 10 cases of asymptomatic adynamic bone among a group of 32 continuous ambulatory peritoneal dialysis patients, most of whom had never been exposed to aluminium-containing phosphate binders. Compared to the remaining 22 patients, they had an older mean age (54 +/- 11.4 vs. 42 +/- 11.8 years; p < 0.05), probably a longer pre-dialysis duration of renal failure (10.9 vs. 7.1 years), higher mean ionized calcium (1.30 +/- 0.04 vs. 1.15 +/- 0.02 mmol/l; p < 0.01), and lower mean intact parathyroid hormone (31.5 vs. 200.3 pg/ml; p < 0.001). The bone density was not different between the two groups, but 9 of the 10 adynamic patients had significant vascular calcification seen on plain radiology as compared with only 7 of 20 in the comparison group (p < 0.05). Follow-up of the adynamic patients showed a close association with serum intact parathyroid hormone and ionized calcium levels. With one exception, adynamic bone did not appear to be associated with lower bone density than other types of osteodystrophy, but a longer-term study is required to determine the complete natural history of this lesion.

Reduced bone mineral density in patients with adult onset growth hormone deficiency.

We have demonstrated previously that adults with isolated GH deficiency of childhood onset have a reduced bone mineral density (BMD) of vertebral trabecular bone [quantitative computed tomography (QCT): median Z score -1.3, P < 0.01, n = 12] and of cortical bone in the forearm [single photon absorptiometry (SPA): median Z score -2.9, P = 0.001, n = 7]. We have now examined BMD in 26 patients (13 men, 13 women), aged between 23.6 and 59.5 (mean 42.4) yr, with adult onset GH deficiency, defined as a GH response of less than 5 micrograms/L to provocative testing, of at least two years duration. BMD was measured using QCT for vertebral trabecular bone, dual energy x-ray absorptiometry (DXA) in the lumbar spine and femoral neck, and SPA in the forearm. There was a highly significant reduction in QCT (median Z score -1.07, P < 0.00005), in DXA of the lumbar spine (median Z score -0.76, P = 0.0001) and in SPA of the forearm (median Z score -0.86, P = 0.0001) but not in DXA of the femoral neck (median Z score -0.38, P = 0.35). There were no significant differences in Z scores between those patients with isolated GH deficiency and those with GH and gonadotrophin deficiency. There was a significant positive correlation between age at which BMD was measured and Z score (the older the patient, the higher the Z score) for QCT (r = 0.38, P < 0.05) and SPA (r = 0.48, P < 0.01) with a trend to a positive correlation for DXA of the lumbar spine and femoral neck. Patients were grouped according to estimated duration of GH deficiency (less than 5 yr, n = 7; 5-10 yr, n = 10; greater than 10 yr, n = 9). These groups did not show a significant difference in BMD at any site. We conclude that patients with adult onset GH deficiency (isolated or in conjunction with other pituitary hormone deficiencies) have a reduced BMD. Age at development of GH deficiency may be more important than duration of GH deficiency in determining the degree of reduction in bone mass. The impact of GH treatment on BMD in adults with adult onset GH deficiency requires investigation.

Radiographic abnormalities in the feet of patients with diabetic neuropathy.

OBJECTIVE: To investigate the prevalence of radiographic bone and joint abnormalities in the feet of diabetic patients. RESEARCH DESIGN AND METHODS: In a blinded randomized study, 94 diabetic patients with peripheral neuropathy (54 with a history of foot ulcers) and 43 non-neuropathic patients were drawn at random from the data base of a large university diabetes clinic in the United Kingdom. Fifty nondiabetic age-matched control subjects also were studied. Lateral and dorsi-plantar weight-bearing plain radiographs of the foot and ankle were taken by a single radiographer. Abnormalities in the bones and joints were determined according to a structured reading of the radiographs by a single radiologist. RESULTS: Diabetes per se resulted in no excess of bony abnormality. Diabetic patients with neuropathy had significantly more radiographic abnormalities of the bones and joints than non-neuropathic and age-matched nondiabetic control subjects. However, except for periosteal reaction, this was predominantly caused by an excess of abnormalities in diabetic patients with a history of foot ulceration. Traumatic fractures (most previously unrecognized) were found in 12 (22%) of the 54 neuropathic patients with previous foot ulceration, and 9 (16%) patients who had experienced foot ulcers exhibited characteristic Charcot changes. CONCLUSIONS: These results suggest that bony abnormalities, particularly Charcot changes and traumatic fractures, are more frequent than previously recognized in neuropathic diabetic patients, especially in those with a history of foot ulceration. Early recognition of bony abnormality and appropriate treatment may prevent progression of foot deformity and thereby reduce the morbidity caused by ulceration or reulceration.

Comparable detection of acute myocardial infarction by creatine kinase MB isoenzyme and cardiac troponin I.

Although measurement of cardiac troponin I (cTnI) is, in some situations, more specific for detection of cardiac injury than is measurement of the MB isoenzyme of creatine kinase (MBCK), its sensitivity and specificity relative to MBCK for detection of myocardial infarction has not been established. Accordingly, we studied prospectively 199 consecutive patients admitted to the coronary care unit. Values of MBCK and cTnI mass were determined in all samples. Of the 188 patients admitted with a suspicion of acute myocardial ischemia, 89 were diagnosed as having an acute myocardial infarction on the basis of the patterns of MBCK values. Eighty-six of these patients also had increased cTnI (concordance, 96.6%); three did not. Of the patients diagnosed as without infarction, five with unstable angina and symptoms in the day(s) prior to admission had increased cTnI, for a cTnI specificity of 94.9%. Receiver operating characteristic curve analysis indicated that cTnI and MBCK had statistically indistinguishable diagnostic accuracies for the detection of acute myocardial infarction.

Medial arterial calcification in the feet of diabetic patients and matched non-diabetic control subjects.

The prevalence and distribution of medial arterial calcification was assessed in the feet of four subject groups; 54 neuropathic diabetic patients with previous foot ulceration (U), median age 60.5 (50.5-67 interquartile range) years, duration of diabetes 19.5 (9.9-29.9) years; 40 neuropathic diabetic patients without a foot ulcer history (N), age 68 (62-73) years, duration of diabetes 14.0 (8.0-28.0) years; 43 non-neuropathic diabetic patients (NN), age 60.5 (52-68.5) years, duration of diabetes 14.0 (8.0-28.0) years and 50 non-diabetic control subjects, age 62.5 (53.7-70) years. A single radiologist graded medial arterial calcification as absent, mild or severe, at the ankle, hind-foot, mid-foot, metatarsals and toes on standardised plain lateral and antero-posterior foot radiographs taken by a single radiographer. Diabetes history, vibration perception threshold, ankle systolic pressure and serum creatinine were also assessed. Medial arterial calcification was significantly greater (total score 18 [3-31]) in neuropathic diabetic patients with previous ulceration (U vs N p < 0.01, U vs NN p < 0.001). Non-neuropathic diabetic patients did not have significantly higher arterial calcification scores than age-matched non-diabetic control subjects. Medial arterial calcification correlated with vibration perception threshold (r = 0.35), duration of diabetes (r = 0.32) and serum creatinine (r = 0.41), (all p < 0.01). Logistic regression models showed vibration perception and duration of diabetes to predict the probability of any calcification. Serum creatinine level was added to predict severe calcification.(ABSTRACT TRUNCATED AT 250 WORDS)
