Accumulation of oxidized proteins and impaired antioxidant system have been shown to be associated with arthritis. Serum sialic acid (SA) is known as a parameter of inflammation. In the present study, to explore the potential role of SA in arthritis, we measured serum SA levels, plasma protein oxidation, and antioxidant status in patients with primary osteoarthritis (POA) and inactive rheumatoid arthritis (RA). Inactive RA (iRA) was defined upon the American College of Rheumatology criteria for clinical remission of RA. A total of 40 patients (20 POA patients, including 4 male subjects, and 20 iRA female patients) and 20 healthy female subjects were included in this study. SA, antioxidants, and protein oxidation levels were determined spectrophotometrically in serum or plasma samples. Serum SA levels were significantly increased in POA (3.34 +/- 0.37 mM, p < 0.0001) and iRA (3.11 +/- 0.47 mM, p < 0.05), compared with healthy controls (2.41 +/- 0.16 mM). Plasma total antioxidant activity, plasma superoxide dismutase activity and serum reduced glutathione levels were significantly decreased in patients with POA and those with iRA, whereas plasma carbonyl content and serum total protein were increased in those patients. Moreover, plasma total thiol levels were significantly increased in iRA and decreased in POA. Thus, increased SA and protein oxidation levels are associated with the decreased antioxidant levels in POA and iRA patients. These results suggest that SA may be considered as a potent defense molecule against oxidative damage in arthritis. Antioxidant therapy may halt or ameliorate the progression of arthritis. 相似文献

The aim of this study was to determine the clinical, laboratory, and endoscopic findings that might be related to poor prognoses,
such as rebleeding or death, in patients admitted to the emergency room with upper gastrointestinal (UGI) bleeding. A prospective
evaluation was conducted in 99 patients with UGI bleeding who were admitted to the emergency room of Hacettepe University
Medical School between May and December 2001. Twenty-four patients were considered to have a poor prognosis. In multivariate
analyses, presence of diabetes mellitus or of visible vessel at endoscopy, treatment with proton pump inhibitors, and decrease
in mean blood pressure were found to be independent predictors for poor prognoses in this population. Several factors, such
as comorbidities, type of treatment, or clinical and endoscopic findings, were found to be related to rebleeding or death
in patients admitted to the emergency room with UGI bleeding necessitating intensive care. 相似文献

Sweet's syndrome is a multisystem inflammatory disorder characterized by painful, erythematous plaques and aseptic neutrophilic infiltration of various organs. The absence of vasculitis is a histological criterion for diagnosis, but recent reports suggest that vasculitis can occur in Sweet's syndrome. Involvement of the central nervous system and the pulmonary system is very rare. In this case study we describe a chronic alcoholic man with Sweet's syndrome associated with acute-onset encephalitis and severe pulmonary involvement. The patient's symptoms responded dramatically to steroid treatment, and notably, a skin biopsy of his lesions showed vasculitis. 相似文献

Objective: To verify effects of kinesio taping (KT) in shoulder subacromial impingement syndrome (SIS) when compared to sham taping applied in the same way with KT. Patients and Methods: Patients were randomized as group 1 (n = 21) KT group and group 2 (n = 20) sham-taping group. Taping was applied every three days, three times during the study period. We assessed all the patients at baseline, at the end of the taping period (12th day), and at one-month post-intervention. We assessed pain on the 100 mm visual analog scale (VAS). Shoulder range of motion (ROM), Constant Scores, and Nottingham Health Profile (NHP) scores were evaluated. Results: Of the 41 participants, 13 were males (32%) and 28 were females (68%). The mean age was 45 ± 15 years (range 20–65 years). We documented a significant decrease in VAS for nocturnal pain, and Constant Score in both groups. The KT group showed additional significant change in NHP pain and physical activity scores. Conclusion: KT and sham taping generated similar results regarding pain and Constant Scores. 相似文献

Despite the presence of various nerve coaptation materials and techniques, achievement of the functional nerve regeneration is still inadequate. This study was aimed to compare
the effectiveness of conduit composed of collagen biomatrix and omentum graft on peripheral nerve regeneration. Thirty-five
male Wistar rats were divided into four groups. In the control group, the right sciatic nerve was skeletonized from the sciatic
notch till the point of bifurcation. In the primary epineural repair group, the nerve was transected 1 cm proximal to the
bifurcation with a sharp pair of micro scissors and then repaired with four epineural sutures. In the collagen biomatrix group,
the epineural repaired nerve was wrapped with collagen biomatrix. In the collagen group, the epineural repaired nerve was
wrapped with the nonpediculated omentum. Assessment of the nerve regeneration was based on functional (Walking Track Analysis,
Electrophysiological Measurements), histological, and morphometric criteria. Light and electron microscopic examinations showed
that collagen-biomatrix-wrapped specimens have the best regeneration. The electrophysiological study confirmed the recovery
of electrical activity in the regenerated axons. 相似文献

In order to get early information on the functional state of smaller myelinated fibers this article investigated the applicability of conduction velocity distribution on compound action potential recorded in experimentally demyelinated frog sciatic nerve. Conduction velocity distribution histograms were estimated by using the mathematical model the authors enhanced. The results suggest that by using appropriate conduction velocity distribution model the diagnosis time in demyelinating neuropathy may be shortened at least three times as compared with conventional conduction velocity assessment. Therefore, it may be concluded that a well-defined model designed for the estimation of the conduction velocity distribution may be used as a diagnostic tool for the early phase of peripheral demyelinating neuropathies. 相似文献

Background Typical hypomimia develops in almost all Parkinson’s disease (PD) patients. We observed the presence of hemihypomimia (HH)
in some of our PD patients.
Objective To discern the presence of hemihypomimia, to compare clinical features of these patients with the patients without HH and
then to evaluate HH prospectively.
Methods Among 353 patients with PD followed-up between September 2003 and December 2004, 204 patients in stage 2 of Hoehn-Yahr were
evaluated and hemihypomimia was observed in 13 PD patients (6.4%). Two groups were compared with respect to the age of onset
of the first PD symptom, duration of PD and the body side affected predominantly. In addition, persistence of HH was prospectively
evaluated in 11 of 13 patients with HH up to two-year-follow up period.
Results Hemihypomimia was interestingly on the right side of the face in all patients. Of these 13 HH patients, all but one had predominantly
right-sided PD symptomatology. In the comparison of HH patients with the remaining group (n = 191), patients with HH had significantly
earlier onset of PD symptoms (mean: 53.9 vs 58.5 years), and shorter PD duration (mean: 4.0 vs 6.2 years) (p < 0.01). Up to
two-year-follow up, hemihypomimia, which was not changed by several triggered emotional facial expressions, clinically persisted.
Conclusion Our observations suggest that hemihypomimia is a rare phenomenon in PD, especially in PD patients having early-onset and shorter
PD duration which may persist for several years in concordance with typical asymmetrical involvement of the limbs. HH developed
in the right side, prominently on the lower part of the face. Understanding the underlying mechanism(s) about how hemihypomimia
appears, and why it dominantly affects the right side of the face deserves further assessment.

Pancreatic cystadenocarcinoma is an extremely rare neoplasm in pregnancy. To our knowledge, there have been 2 published cases of pancreatic mucinous cystadenocarcinoma (PMC) during pregnancy in the literature; one of which was reported to have ruptured into the abdominal cavity. We present a second case of ruptured PMC resulting in acute abdomen in 36 weeks of pregnancy. Rupture of mucinous cystic neoplasms of pancreas including PMC should be remembered in acute abdomen during pregnancy. 相似文献
