The principles of treatment of tibial pseudoarthroses complicated by skin and soft tissue loss with the use of cancellous bone grafts from posterolateral approach to the tibia by Harmon method were discussed. The detailed surgical technique was presented. Management of 3 patients that resulted in bone union was described. 相似文献

The aetiology of porphyria cutanea tarda (PCT) has not been elucidated, but the possibility of an autoimmune mechanism has been proposed. We report a case of an unknown clinical combination of PCT with autoimmune hypothyroidism, alopecia universalis and vitiligo with thyroid and parietal cell circulating antibodies. This is highly suggestive of underlying autoimmune damage in this patient. 相似文献

Histologic structure of Mueller's adenosarcoma has been studied in 5 patients subjected to uterine and its appendages extirpation. Microspectrophotometric assessment of the course of nuclear DNA accumulation, measurement of X-chromatin in two morphologic components of the tumor (epithelial and stromal) confirmed malignant morphological nature of the latter and benign one of the former. Basing on their experience with the 5 patients three of which died in the course of 5 years of relevant metastases, the authors believe the prognosis for uterine adenosarcoma to be poor. 相似文献

Analyses of serum vitamin D-binding protein, ceruloplasmin and copper levels in preterm infants. 总被引:1,自引:0,他引:1
The cord blood specimens of 12 preterm and 20 term babies were investigated. We determined serum calcium (Ca), phosphorus (P), magnesium (Mg), vitamin-D binding protein (DBP), ceruloplasmin (Cp) and copper (Cu) levels in two groups. We found that Ca, P, and MG levels of cord sera did not differ between the groups (p > 0.05), but DBP, Cp and Cu values showed a significant decrease in the preterm group (p < 0.05). The Cu and Cp values of the preterm infants correlated with those of the term infants. 相似文献

We studied pulmonary haemodynamics and nocturnal desaturation in 17 patients with an overlap syndrome (OS), all males, mean age 51.4 +/- 8.3 years, mean BMI 37 +/- 4.2 kg/m2. Diagnosis of COPD was based on pts history, clinical examination, lung function tests and chest radiography. Spirometry showed: FVC 2.7 +/- 0.7 L (59 +/- 16% N), FEV1 1.5 +/- 0.7 L (43 +/- 16% N), FEV1% FVC 54 +/- 13%, Raw 0.58 +/- 0.4 kP.s/L, RV 3.3 +/- 1.2 L (144 +/- 51% N), TLC 6.6 +/- 1.3 L (100 +/- 14% N) and RV% TLC (49.5 +/- 12.1%. Arterial blood gas values were: PaO2 56.9 +/- 9.5 mmHg, PaCO2 46.9 +/- 9.8 mmHg, pH 7.37 +/- 0.05. Mean apnoea/hypopnoea index (AHI) was 63.9 +/- 18.9. Pulmonary haemodynamics at rest (Swan Ganz thermodilution catheter) were: mean pulmonary artery pressure (PAP-SP) 24.2 +/- 7.4 mmHg, mean pulmonary wedge pressure (PW-SP) was 9.1 +/- 7.3 mmHg, cardiac output (CO-SP) was 5.6 +/- 2.3 L/min. and pulmonary vascular resistance (PVR) was 229 +/- 97 dyn.sec.cm-5. During exercise (40 Watts, 7 mins, in 8 pts) PAP rose from 19 +/- 6 mmHg to 41.2 +/- 15.1 mmHg, PW rose from 7.4 +/- 7.2 mmHg to 11 +/- 10.2 mmHg, CO rose from 5.8 +/- 2.7 L/min to 12.7 +/- 2.4 L/min. Overnight pulse oximetry showed: mean oxygen saturation (SaO2 mean) 80.2 +/- 8.5%, minimal saturation (SaO2 min) was 50.7 +/- 19.7%. Time spent in desaturation SaO2 < 90% (T 90) was 76.9 +/- 25.7%. We conclude that pts with OS have resting pulmonary hypertension and elevated PVR. During low grade exercise the rise in PAP was highly abnormal. Statistical analysis showed no correlations between nocturnal SaO2 and diurnal pulmonary haemodynamics data. 相似文献

Adrenaline was determined in injections containing procaine in a 1000-fold excess by reversed-phase high-performance liquid chromatography using UV detection at 205 nm and aqueous sulphuric acid (100 μmol/l) as eluent. The relative standard deviation was 2.1%, and the method was selective in the presence of adrenaline degradation products. Changes of the capacity factor with pH and ionic strength of the eluent were studied, and a simple model is suggested to explain the retention data. 相似文献

Participant attitudes are an explanatory factor for attrition in online health-related interventions. However, its assessment prior to interventions start is uncommon, partly because proper measures are missing. This study presents the psychometric properties of a new scale measuring attitudes towards online psychoeducational interventions (OPIs). Structural validity, reliability and screening performance of the Online Psychoeducational Intervention – Brief Attitudes Scale (OPI-BAS) were studied in a sample of 157 dementia caregivers. Scale cut-off scores were derived to categorise the participants into ‘OPIs sympathisers’ or ‘non-sympathisers’. Groups were compared across sociodemographic and internet use variables. A parsimonious five-item version of OPI-BAS demonstrated good structural validity, with one factor explaining 63.3% of variance. Internal consistency of the scale was high (α = 0.85). OPI-BAS showed good screening performance in identifying individuals with either a preference to use conventional face-to-face or online psychoeducational interventions (area under the curve = 0.84). An optimal cut-off score of 20 was suggested by the receiver operating characteristic graph, providing good sensitivity (74%) and specificity (84%). No significant differences were found between groups on sociodemographic and internet use variables. Attitudes towards OPIs were overall positive, but face-to-face interventions were preferred. This study offers preliminary support to the psychometric quality of OPI-BAS. This short scale has practical applications for research and intervention. 相似文献

Usually neglected is the role of neutrophils in causing of immunological disturbances in patients with multiple sclerosis (MS). Nevertheless, it has been indicated over the recent years that these cells possess a sufficient potential to affect both immune response and inflammation. This potential may result in MS through the process of priming of these cells by proinflammatory cytokines like TNF. We studied TNF and its soluble receptors sp55 and sp75 serum levels and binding of fluorescein isothiocyanate (FITC)-stained TNF by neutrophils. We studied three different groups of MS patients: 10 patients in relapse of the disease, 13 in its remission, and 11 in its chronic progressive form (CP-MS). The control was provided by 14 neurological patients (OND) with non-inflammatory diseases. The performed studies showed higher TNF sp55 and sp75 soluble TNF receptors serum levels in the patients with relapse, comparing with other MS patients and OND. TNF binding by neutrophils of MS patients during relapse was also higher, than other MS patients and OND. These result suggest the preactivation of neutrophils in the relapse of MS. 相似文献
