The effect of six different solutions (normal saline, ringer's lactate, chlorhexidine, povidone iodine, ceftriaxone, chloramphenicol) on articular cartilage was investigated in an in vivo rabbit model study. The right knees were aspirated and injected with one of these solutions for five days and, three days later, the patellae of the rabbits were excised and investigated histologically. Left knees were used as controls. There was no difference between the groups and the controls with respect to structure, cell density, and nuclei-to-lacunae ratio. These results suggest that, these solutions have no noxious effects on articular cartilage when used as irrigating fluids in orthopaedic practice. 相似文献

Chronic hepatitis C (CHC) patients with treatment failure (TF) remain at risk of continuing fibrosis progression. However, it has not been investigated whether there is an increased risk of accelerated fibrosis progression after failed interferon‐based therapy. We aimed to investigate long‐term influence of TF on fibrosis progression compared with untreated patients with CHC. We studied 125 patients with CHC who underwent paired liver biopsies from 1994 to 2012. Patients with advanced fibrosis were excluded from the analysis. Sixty‐three patients had TF, and 62 patients were treatment‐naïve (TN). Annual fibrosis progression rate (FPR) was calculated, and significant fibrosis progression (SFP) was defined as ≥2 stage increase in fibrosis during follow‐up. Multiple regression analyses were performed to find out independent predictors of FPR and SFP. Demographic characteristics and duration between paired liver biopsies were similar in TF and TN groups. Baseline alanine aminotransferase and gamma‐glutamyl transferase (GGT) levels (71 ± 31 vs 47 ± 22, P < 0.001 and 49 ± 39 vs 36 ± 28, P = 0.027, respectively), baseline mean fibrosis stage (2.2 ± 0.7 vs 1.9 ± 0.7, P = 0.018) and histologic activity index (6.3 ± 1.9 vs 4.3 ± 1.6, P < 0.001) were higher in the TF group compared with the TN group. In regression analyses, the strongest independent predictor of fibrosis progression was the GGT level (OR: 1.03, 95%CI 1.01–1.5, P < 0.001). Treatment experience (OR: 5.97, 95%CI 1.81–19.7, P = 0.003) also appeared as an independent predictor of both FPR and SFP. Failed interferon‐based CHC treatment may lead to accelerated FPR in the long‐term compared with the natural course. 相似文献

BACKGROUND AND OBJECTIVE: This study reports on the demographic features, clinico-pathological results and prognoses of patients aged less than 36 years diagnosed with non-small cell lung cancer (NSCLC). METHODS: This is an observational study of patients with primary NSCLC who had a surgical procedure at a tertiary thoracic surgery centre in Turkey. Data collected were age, gender, history of smoking, symptoms, postoperative histopathological diagnosis, stage, surgical procedure and survival. RESULTS: Of the 31 patients in the study, 27 were male (87%) and the median age was 32 years (10-35 years). Nineteen patients were smokers (61.2%). The most common presenting symptom was cough (n = 23, 67.7%). Histopathological diagnosis was squamous cell carcinoma (SCC, n = 17), adenocarcinoma (n = 12), lymphoepithelioma-like carcinoma (n = 1) and undifferentiated carcinoma (n = 1). Staging of the 17 patients with SCC (58.8%) was stage I and II (n = 10, 58%), and stage III (n = 7, 41%). Staging of the 13 patients with adenocarcinoma was stage IV (n = 2, 16%) and stage III patients (n = 8, 66%). Follow-up data were available on 22 patients (71%) and showed a median survival of 17.2 months. Two and 5-year survival rates were 54.5% and 45.5%, respectively. CONCLUSIONS: SCC comprised a relatively high proportion of NSCLC in these younger patients. Aggressive multimodality treatment may achieve satisfactory 2- and 5-year survival rates in young patients with NSCLC who usually present with advanced disease. 相似文献

Macrovascular changes in mice overexpressing human semicarbazide-sensitive amine oxidase in smooth muscle cells 总被引:1,自引:0,他引:1

BACKGROUND: The catalytic activity of semicarbazide-sensitive amine oxidase (SSAO) is increased in diabetes, as well as in other disorders of cardiovascular origin. Our hypothesis is that SSAO is involved in the synthesis or maturation of elastin in vascular tissue. An increased SSAO activity can thereby be involved in the development of vascular damage. METHODS: Elastin quantification was performed in aorta of transgenic mice overexpressing the human form of SSAO, using electron microscopy. Furthermore, lung capacity was measured using a spirometry-mimicking method, developed for mice. The effect of vasoactive substances was estimated by measuring mean arterial pressure and pulse pressure under anesthesia. RESULTS: No differences in elastin quantity or lung capacity could be observed between transgenic or nontransgenic littermates. Pulse pressure was higher in transgenic mice, and electron microscopy of aorta showed elastin fibers parallel with the aorta wall (ie, straight fibers instead of folded compared with control mice). No difference in the response to adrenaline or sodium chloride was observed between the transgenic and control mice. The control mice had a clear decrease in blood pressure (BP) with a longer duration as a response to injection of a nitric oxide (NO) donor, sodium nitroprusside, compared with transgenic mice where only a minor response was observed. The SSAO activity in serum of control mice was elevated in response to injection of the NO donor, but not in response to a ganglion blocker. CONCLUSIONS: An elevated pulse pressure, together with an abnormal elastin structure in the aorta, suggests a rigidity of large arteries as a result of an elevated SSAO activity as well as a physiologic role for SSAO in elastin maturation. 相似文献

Keles S, Artac H, Kara R, Gokturk B, Ozen A, Reisli I. Transient hypogammaglobulinemia and unclassified hypogammaglobulinemia: ‘Similarities and differences’.Pediatr Allergy Immunol 2010: 21: 843–851.© 2010 John Wiley & Sons A/S Transient hypogammaglobulinemia of infancy (THI) is characterized by recurrent infections and one or more reduced serum immunoglobulin (Ig) levels. Usually, this clinical picture resolves spontaneously by 3 yr of age. However, hypogammaglobulinemia persists until adolescence in some patients. In recent years, those patients have been classified as undefined/unclassified hypogammaglobulinemia (UCH). We aimed to evaluate the clinical and immunologic features of patients with THI and UCH considering age of recovery and to assess relationships between hypogammaglobulinemia, infections, and allergic manifestations. We reviewed the medical records of children followed with a diagnosis of hypogammaglobulinemia from 2001 to 2007. Patients with decreased levels (<2 s.d.) of one or more major Ig isotypes (IgG, IgA, IgM) with normal antibody responses and lymphocyte subpopulations were included (n = 374). Those patients whose Igs normalized during the follow‐up period were classified as THI and the others as UCH. The THI group consisted of 71 patients (27 females, 44 males) with a mean recovery age of 68.87 ± 36.5 months. About 95% of patients with THI recovered before 10 yr of age. The UCH group consisted of 303 patients (105 females, 198 males) with a mean age at diagnosis of 52 ± 42 months. The most common presenting manifestations in the THI and UCH groups were upper respiratory tract infections (URTIs), lower respiratory tract infections, and asthma (42%, 50%, and 52% in the THI group vs. 39%, 53%, and 55% in the UCH group, respectively). In the THI group, the prevalence of atopic disease was related to age and found to be increased markedly after 44 months. In all patients, the prevalence of asthma was independently and positively associated with family history of atopy and age, whereas it was negatively associated with recurrent URTIs. Patients with THI and UCH have similar clinical and immunologic features. The normalization of Igs may be delayed in a majority of the patients with hypogammaglobulinemia. This observation may be a contribution to the classical definition and diagnostic criteria for THI. 相似文献

An unusual and rare gastric mucosal lesion histologically consisting of Russell bodies and plasma cell infiltration and termed as Russell body gastritis is presented. In the literature there are only ten such case reports and of these, seven including this present case were associated with Helicobacter pylori infection. The high rate of Helicobacter pylori infections in cases of Russell body gastritis suggests that the correlation is not merely coincidental. All data in the literature related to Russell body gastritis were scanned, and histopathologic findings and the clinical characteristics associated with such lesions were discussed. 相似文献

Spinal tuberculous abscesses usually respond to anti-tuberculous drugs. The purpose of this study was to evaluate the results of surgical drainage after failure of first-line anti-tuberculous drugs. Patients with spinal instability or vertebral collapse were excluded from the study. The authors retrospectively reviewed 11 patients. The operation was successful in all patients. Anterior/posterior spinal fusion or curettage was not performed. Drains were removed after two to three days. None of the patients required a second operation. Complications, such as spinal instability, vertebral collapse, or death did not occur. 相似文献
