Background
There is a lack of understanding on relationship between the femoral geometry and outcomes of total hip arthroplasty (THA). We investigated clinical and radiographic outcomes of THA using a cementless tapered wedge stem in patients with Dorr type A proximal femoral morphology and compared with those of type B femurs at a minimum follow-up of 5 years.Methods
We analyzed 1089 hips (876 patients) that underwent THA using an identical cementless tapered wedge stem. We divided all femurs into 3 types (Dorr type A, B, and C). Type A and B femurs were statistically matched with age, gender, body mass index, and diagnosis by using propensity score matching. Clinical, radiographic results, and stem survivorship were compared between the matched 2 groups.Results
A total of 611 femurs (56%) were classified as type A, 427 (39%) as type B, and 51 (5%) as type C. More radiolucent lines around femoral stems were found in type A femurs (7.8%) than in type B femurs (2.5%) (P < .001). Patients with radiolucency showed worse Harris Hip Score (86.2 points) compared with those without radiolucency (93.0 points) (P < .001). The stem survivorship of type A femur (97.8%) was lower than that of type B femur (99.5%) (P = .041). The reasons for femoral revision in type A femurs were periprosthetic fracture (67%), aseptic loosening (22%), and deep infection (11%).Conclusions
This study showed a higher rate of complications after THAs using a cementless tapered wedge stem in Dorr type A femurs than those performed in type B femurs. 相似文献122.

PURPOSE: To use a pooled analysis of the literature to find the incidence of and characteristics common to intracranial hemorrhage (ICH) associated with carotid artery stenting (CAS). METHODS: A search of the English-language literature (1996-2005) was performed in PubMed to find cases of CAS-associated ICH. Information was derived from the identified case studies in 5 categories and 19 aspects: (1) incidence of CAS-associated ICH; (2) demographic data (sex, age, symptom presentation, and presence of preexisting hypertension); (3) imaging data (side of lesion, degree of maximal stenosis, lesion location, status of the contralateral carotid artery, collateral circulation, and preprocedural imaging features); 4) procedure-related characteristics (antithrombotic medication, use of cerebral protection devices, residual stenosis, symptoms, interval from the procedure to ICH, type of ICH, and blood pressure changes); and (5) clinical outcome. RESULTS: Fifty-four cases of CAS-associated ICH were reviewed: 51 cases from 36 published articles and our own 3 cases. The incidence of CAS-associated ICH was 0.63% (95% CI 0.38% to 0.97%) in studies consisting of >100 cases, which was significantly lower (p<0.0001) than that of case series consisting of <100 cases (2.69%, 95% CI 1.75% to 3.94%). Distinctive features included symptomatic lesions, severe stenosis (> or =90%), maximal stenosis in the internal carotid artery (ICA) distal to the bifurcation, and preexisting cerebral infarction. CONCLUSION: The incidence of CAS-associated ICH was significantly lower in series consisting of >100 cases. More caution should be directed toward patients with symptomatic lesions, severe stenosis, maximal ICA stenosis distal to the carotid bifurcation, and preexisting cerebral infarction. 相似文献

We developed a blood glucose management system using the Internet and short message service (SMS) which can lessen the social economic burden and materialize an individualized diabetes mellitus management. A total of 185 diabetic patients participated in this study and their mean age was 42.4 years old (8-79 year-old). Participants sent their self-measured blood glucose levels, medication and its dosages, amount of meal, and degree of exercise to their health providers in this specialized web-based diabetes management system for 3 months. The health providers consisting of endocrinology specialists, dietitians, and nurses sent recommendations for individualized diabetes management according to the data on the web. Laboratory tests including lipid profiles and glycated hemoglobin (HbA1c), and a survey of satisfaction about this system were performed before and after the study period. The mean HbA1c improved from 7.5 +/- 1.5 to 7.0 +/- 1.1% after using the management program (P = 0.003). The mean serum triglyceride and HDL-cholesterol levels turned for the better also. HbA1c improved from 8.4 +/- 1.2 to 7.5 +/- 1.0% after applying this program to patients with the HbA1c of 7% or higher at baseline (P = 0.010). We propose this web-based diabetic patient management system as a new tool for communication between health care providers and patients. 相似文献

This study was aimed to observe that extremely low frequency magnetic field (ELF-MF) may be relevant to changes of major neurotransmitters in rat brain. After the exposure to ELF-MF (60 Hz, 2.0 mT) for 2 or 5 days, we measured the levels of biogenic amines and their metabolites, amino acid neurotransmitters and nitric oxide (NO) in the cortex, striatum, thalamus, cerebellum and hippocampus. The exposure of ELF-MF for 2 or 5 days produced significant differences in norepinephrine and vanillyl mandelic acid in the striatum, thalamus, cerebellum and hippocampus. Significant increases in the levels of serotonin and 5-hydroxyindoleacetic acid were also observed in the striatum, thalamus or hippocampus. ELF-MF significantly increased the concentration of dopamine in the thalamus. ELF-MF tended to increase the levels of amino acid neurotransmitters such as glutamine, glycine and γ -aminobutyric acid in the striatum and thalamus, whereas it decreased the levels in the cortex, cerebellum and hippocampus. ELF-MF significantly increased NO concentration in the striatum, thalamus and hippocampus. The present study has demonstrated that exposure to ELF-MFs may evoke the changes in the levels of biogenic amines, amino acid and NO in the brain although the extent and property vary with the brain areas. However, the mechanisms remain further to be characterized. 相似文献

Hypernatremic dehydration is an important cause of intracranial hemorrhage. A possible association of intraventricular hemorrhage (IVH) with hypernatremia and/or high sodium intake has been suggested in preterm infants. To investigate the associations of early fluid and sodium intake or serum sodium concentrations with severe intraventricular hemorrhage (IVH) in extremely low birth weight (ELBW) infants, we reviewed the medical records of 169 inborn ELBW infants. Daily fluid and sodium intake, urine output, weight loss and serum sodium concentration during the first 4 days of life were obtained. Patients were divided into the severe IVH (grade 3/4) and the control (no or grade 1/2 IVH) group. The maximum serum sodium concentration and the incidence of hypernatremia did not differ between the two groups. Related to the fluid balance and sodium intake, the risk for severe IVH was strongly associated with total fluid and sodium intake during the initial four days of life. With respect to the fluids other than transfusion, severe IVH can be discriminated only by sodium intake but not by fluid intake. Large randomized controlled trials are required to clarify the causal relationship between the early sodium intake and severe IVH in ELBW infants.

The aim of this study was to investigate the whole picture regarding pregnancy, prenatal care, obstetrical complications, and delivery among disabled pregnant women in Korea. Using the data of National Health Insurance Corporation, we extracted the data of women who terminated pregnancy including delivery and abortion from January 1, 2010 to December 31, 2010. Pearson''s chi-square test and Student-t test were conducted to examine the difference between disabled women and non-disabled women. Also, to define the factors affecting inadequate prenatal care, logistic regression was performed. The total number of pregnancy were 463,847; disabled women was 2,968 (0.6%) and 460,879 (99.4%) were by non-disabled women. Abortion rates (27.6%), Cesarean section rate (54.5%), and the rate of receiving inadequate prenatal care (17.0%), and the rate of being experienced at least one obstetrical complication (11.3%) among disabled women were higher than those among non-disabled women (P < 0.001). Beneficiaries of Medical Aid (OR, 2.21) (P < 0.001) and severe disabled women (OR, 1.46) (P = 0.002) were more likely to receive inadequate prenatal care. In conclusion, disabled women are more vulnerable in pregnancy, prenatal care and delivery. Therefore, the government and society should pay more attention to disabled pregnant women to ensure they have a safe pregnancy period up until the delivery.
