The aim of the study was clinical and X-ray evaluation of two patients treated because of fractures of shaft of femur with coexisting hip joint osteoarthritis with cemented THR. Both patients were treated just after the injury. Reduction of fractures were made to both patients. Stabilization of fracture in one patient was made with metal plate and cables, stabilization with only cables was made to second patient. Exeter THR with standard stem was implanted to first patient, and with long stem to the second one. Both patients have good clinical results - 90 and 92 pts. in Harris Hip Score after 36 and 48 months accordingly. The fracture healed in the first patient. The evidence of fracture healing of the second patient was impossible to examine because of lack of X-ray. Conclusions. 1) The use of THR in the treatment of femoral shaft fractures with coexisting osteoarthritis gives a chance of simultaneous fracture treatment and joint replacement. 2) Fracture stabilization requires the use of metal plates and cables. 相似文献

BACKGROUND: Asthma and rhinitis often coexist, and there is evidence to suggest that they have similar histopathologic features. OBJECTIVE: To examine whether the inflammatory infiltration in the nasal mucosa in rhinitis is affected by the presence of asthma and allergy. METHODS: Nasal mucosa biopsy samples were collected from 44 individuals: 18 with rhinitis and asthma (9 allergic and 9 nonallergic), 16 with rhinitis and no asthma (8 allergic and 8 nonallergic), and 10 nonallergic control subjects. The alkaline phosphatase-anti-alkaline phosphatase method was applied to 6-microm-thick cryostat sections using monoclonal antibodies against T cells (CD4 and CD8) and eosinophils (EG2). Slides were counted blindly, and results are expressed as cells per high-power field. RESULTS: Eosinophil counts were higher in the nasal mucosa of rhinitic patients vs controls. No differences in cellular infiltration were detected between rhinitic patients with and without asthma or between allergic and nonallergic patients. A trend toward higher CD4+ T-cell counts in the nasal mucosa of rhinitic patients was observed, whereas no differences were noted in CD8+ T-cell infiltration among the groups. CONCLUSION: Inflammatory infiltration, characterized by the presence of eosinophils and CD4+ T cells, was similar in the nasal mucosa in noninfectious rhinitis irrespective of the presence of asthma or the allergic status of the patient. 相似文献

We have studied the influence of grass pollen immunotherapy on cellular infiltration and cytokine mRNA expression during allergen-induced late-phase cutaneous responses. In a double-blind, placebo-controlled trial of immunotherapy in 40 adult hay fever sufferers, clinical improvement was accompanied by a decrease in the size of the late-phase skin response. When the immunotherapy-treated group was compared with the placebo group, analysis of skin biopsies obtained 24 h after intradermal allergen revealed a significant reduction in the number of infiltrating CD3+ (P = 0.04) and CD4+ (P = 0.009) cells and a trend for a decrease in EG2+ eosinophils (P = 0.08). Treatment did not influence allergen-induced recruitment of CD8+ cells, neutrophils, or macrophages. Unexpected increases in expression of CD25 (P = 0.006) and HLA-DR (P = 0.007) were observed in the actively treated group. In situ hybridization using a panel of riboprobes demonstrated "TH2-type" (IL-4, IL-5) cytokine mRNA responses in both groups of patients. In contrast, significant hybridization for IL-2 (8/16 patients, P = 0.02) and for interferon-gamma (6/16 patients, P = 0.04) was observed only in the actively treated group. These findings indicate that immunotherapy is associated with suppression of allergen-induced CD4+ T lymphocyte infiltration, but among the cells that are recruited, there is upregulation of CD25 and HLA-DR. At least in this model, immunotherapy does not appear to affect expression of TH2-pattern cytokines in response to allergen exposure, but expression of mRNA for Th1-type cytokines was enhanced in half of the patients. The results support the view that immunotherapy may possibly be working through induction of T cell tolerance. 相似文献

Severe asthma affects fewer than 10% of patients with asthma, is associated with a severe risk of death and disability, has a great impact on health and quality of life, and represents a huge cost to patients and society. Given the poor response to treatment and the side effects associated with medications for severe asthma, more efficient, cost-effective, and phenotype-specific medications are needed. Considering severe asthma as an orphan disease could encourage the pharmaceutical industry to stratify studies based on a more detailed characterization of study subjects at baseline, resulting in the development of novel therapeutic approaches. 相似文献

Recently, we have shown that the expired CO2 gas volume versus tidal volume (VCO2-VT) curve is a useful tool for assessing unevenness of ventilation because it allows the separation of tidal volume into three functional compartments: (a) the CO2-free expired air (V0), (b) the transitional volume (Vtr), (c) the alveolar volume (VA) and the measurement of alveolar FCO2 during resting breathing in normal subjects and patients with COPD. In this paper, we have investigated whether changes pertaining to unevenness of ventilation taking place immediately after the administration of methacholine can be assessed using the VCO2-VT curve in asthmatic patients. The VCO2-VT curve was obtained during tidal breathing from 16 stable asthmatic patients who underwent a methacholine challenge test. It has been found that the Vtr, and hence Bohr's dead space (VD,Bohr = V0 + Vtr), over tidal volume ratios were significantly increased immediately after the methacholine administration, whilst the V0 over tidal volume ratio was not affected. The change of the above ratios was not related to the percentage decrease of FEV1.0 following methacholine administration. 相似文献

Background. Clinical material collected from 1989 to 1999 from three orthopedic centers is discussed: the Orthopedic Clinic at the Center for Postgraduate Medical Education in Otwock, the Orthopedic Clinic at the Lublin Academy of Medicine, and the Orthopedic Clinic at the Warsaw Academy of Medicine.
Material and methods. During this period 511 patients with an average age of 66 were treated. The authors explain the reasons for aseptic loosening of hip prostheses, the types of implants replaced, and the methods of surgical treatment.
Analysis of results. The importance of correct surgical technique and modern cementing methods during primary arthroplasty for the duration of good prosthesis functioning is discussed. A good outcome from revision arthroplasty can be expected only when the decision to treat is made early. The authors confirm the usability of impacted camcellous allografts for revision hip arthroplasty. Complications during and after surgery are also discussed. Difficulties in the clinical and radiological evaluation of treatment outcomes caused by differing criteria used in each orthopedic treatment are also discussed in this article.
Conclusions. In the conclusion the authors propose rules for surgical treatment to reduce the number of revision procedures. 相似文献
