Myocardial infarction with normal coronary artery is ussually inaugural, with electric and clinical characteristics similar to those with atheroma. The role of constitutional or acquired abnormalities of haemostasis has been more incriminated in the pathogenesis of myocardial infarction with normal coronary. The aim of our study was to research abnormalities of haemostasis in patients with myocardial infarction and angiographically absolutely normal coronary arteries. PATIENTS AND METHODS: Thirty nine patients with myocardial infarction and normal coronary arteries where included in our study. They were 33 males and 6 females aged between 22 and 75 years (44 + 13 years), in whom the deficiency in protein C and S. antithrombin, activated protein C resistance and antiphospholipid antibodies were assessed. RESULTS: Concurrent abnormalities of haemostasis were found in 10 patients: Antiphospholipid antibodies, found in 5 patients constitute the most frequent abnormality. The other abnormalities were deficiency in protein C in two cases, deficiency in protein S 2 cases, deficiency in antithrombin in 2 ceses and activated protein C resistance in 3 cases . CONCLUSION: In our study. in face of the high prevalence of these abnormalities, it seems reasonable to research them, especially in young patients with myocardial infarction with normal coronary artery. This should have an impact on the management of these patients. 相似文献

Many new lipid- and water-soluble contrast media can be used in sialography, the three main criteria of choice being the cost, the quality of filling, particularly of the parenchyma, and its evacuation and clinical tolerance. Duroliopaque possesses very similar physicochemical properties to those of Lipiodol UF, but a sufficiently satisfactory filling of the parenchyma is not obtained. Comparison of Lipiodol UF and Hexabrix in parotid and submaxillary contrast imaging showed good clinical tolerance for both products, but improved parenchymatous filling with Lipiodol UF. However, the more effective glandular evacuation with Hexabrix makes this the product most suitable at the present time for morphologic exploration of salivary glands. 相似文献

Caffeine metabolites were extracted from urine samples collected 4 h after consumption of a cup of coffee and were separated by high-performance liquid chromatography (HPLC) on a C18 (5 microm) reverse-phase column using an acetonitrile (5%), acetic acid (0.05%) solution as the mobile phase. The elution profiles indicated the constant presence of a major and a minor components eluting between the caffeine metabolites 5-acetamido-6-formyl-3-methyluracil (AFMU) and 7-methylxanthine (7X) in an approximate nine. A procedure was developed for the isolation of the major component in an apparent pure form, and the yield was 10-20 mg from 400 ml of urine. The minor component was isolated in an apparent pure form by this procedure as well, and the yield was 0.5 mg from 200 ml of urine. The average ratio of the two components in urine, UV absorption and 1H-NMR spectra of the two components, and 13C-NMR spectrum, mass spectrum and elemental analysis of the major component identified the major and minor components as N(1)-methyl-2-pyridone-5-carboxamide and N(1)-methyl-4-pyridone-5-carboxamide, respectively, two major metabolites of the vitamin niacin present in a significant amount in coffee beans. The two metabolites were present in the same average amount in urine extracts of individuals irregardless of coffee consumption. The findings are briefly discussed in relation to the nutritional sources of niacin and to current procedures for measuring amounts of the two metabolites in urine samples. 相似文献

Few reports are available on bone turnover in type 2 diabetes. Impaired bone turnover in type 2 diabetes appears to result from decreased bone formation. Studies also suggest that poor glycaemic control in type 2 diabetes may contribute to osteopaenia. The aim of this study was to investigate biochemical markers of bone turnover in males with poorly controlled type 2 diabetes and look for correlations with glycaemic control and gonadal and hypophyseal hormonal axis. Consecutive male patients with poorly controlled type 2 diabetes and attending the internal medicine department during a period of 6 months were enrolled. The patients were receiving oral hypoglycaemic agents (metformin or sulphonylureas or both). None of the patients had any evidence of macroangiopathy, nephropathy or neuropathy. Only two patients had proliferative retinopathy. Serum osteocalcin, crosslaps (C-telopeptide, CTx), parathyroid hormone (PTH), testosterone, oestrogen, prolactin, follicle-stimulating hormone (FSH) and luteinising hormone (LH) were measured in 35 patients and 35 controls. The mean age of the study population was 53.7 (10.3) years (range: 50.2–57.3) and the mean disease duration was 8.6 (6.0) years (range: 6.5–10.7). No differences between patients and controls were observed in serum calcium, phosphorus, creatinine, albumin, PTH, CTx, oestrogen, testosterone, LH, FSH, prolactin and urinary calcium. Patients had lower serum levels of osteocalcin than controls with a significant statistical difference [15.3 (4.1) vs 18.3 (5.3), p=0.012]. There was a negative significant statistical correlation between CTx levels and HbA1c (r=–0.41, p< 0.05). Our study suggested that bone formation is altered in type 2 diabetes and that bone turnover is affected by glycaemic control status. 相似文献

Ceftaroline (CPT), the active metabolite of the prodrug ceftaroline-fosamil (CPT-F), demonstrates in vitro bactericidal activity against methicillin-resistant Staphylococcus aureus (MRSA) and is effective in rabbit models of difficult-to-treat MRSA endocarditis and acute osteomyelitis. However, its in vivo efficacy in a prosthetic joint infection (PJI) model is unknown. Using a MRSA-infected knee PJI model in rabbits, the efficacies of CPT-F or vancomycin (VAN) alone and combined with rifampin (RIF) were compared. After each partial knee replacement with a silicone implant that fit into the tibial intramedullary canal was performed, 5 × 107 MRSA CFU (MICs of 0.38, 0.006, and 1 mg/liter for CPT, RIF, and VAN, respectively) was injected into the knee. Infected animals were randomly assigned to receive no treatment (controls) or CPT-F (60 mg/kg of body weight intramuscularly [i.m.]), VAN (60 mg/kg i.m.), CPT-F plus RIF (10 mg/kg i.m.), or VAN plus RIF starting 7 days postinoculation and lasting for 7 days. Surviving bacteria in crushed tibias were counted 3 days after ending treatment. Although the in vivo mean log10 CFU/g of CPT-treated (3.0 ± 0.9, n = 12) and VAN-treated (3.5 ± 1.1, n = 12) crushed bones was significantly lower than those of controls (5.6 ± 1.1, n = 14) (P < 0.001), neither treatment fully sterilized the bones (3/12 were sterile with each treatment). The mean log10 CFU/g values for the antibiotics in combination with RIF were 1.9 ± 0.5 (12/14 were sterile) for CPT-F and 1.9 ± 0.5 (12/14 were sterile) for VAN. In this MRSA PJI model, the efficacies of CPT-F and VAN did not differ; thus, CPT appears to be a promising antimicrobial agent for the treatment of MRSA PJIs. 相似文献
