The cases are reported of two patients with chronic Lyme arthritis resistant to the recommended antibiotic regimens who were cured by long term treatment with benzathine penicillin. It is suggested that the sustained therapeutic levels of penicillin were effective either by the inhibition of germ replication or by lysis of the spirochaetes when they were leaving their sanctuaries.  相似文献

Plasma fibronectin in psoriatic arthritis subgroups   总被引:1,自引:0,他引:1  
Summary Plasma from 38 patients suffering from one of the five broad clinical subgroups of Psoriatic Arthritis (PA) were studied for soluble plasma Fibronectin (pFn). The mean total concentration of pFn was 453.03g/ml ± 142.83 SD, with a significant statistical difference (p<0.01) versus a healthy control group matched with respect to sex and age. In order to evaluate the biological role that pFn might play in this pathological condition, observed concentrations were correlated with the degree and duration of the psoriasis and arthritis. In addition, pFn was correlated to some biohumoral parameters that are modified during inflammatory processes (ESR, CRP, sCu, sFe, Hb) and to uric acid levels. Tissue typing (HLA) was done where possible. From our observations, we suggest that pFn most likely is not an acute phase protein and rather than having specificity for a particular disease, might, in widespread and severe cases be,a general and useful marker of the connective-tissue organizing and repairing response, following its injury.  相似文献

We characterize and decipher the resistome and the virulence factors of Shewanella algae MARS 14, a multidrug-resistant clinical strain using the whole genome sequencing (WGS) strategy. The bacteria were isolated from the bronchoalveolar lavage of a hospitalized patient in the Timone Hospital in Marseille, France who developed pneumonia after plunging into the Mediterranean Sea. Results: The genome size of S. algae MARS 14 was 5,005,710 bp with 52.8% guanine cytosine content. The resistome includes members of class C and D beta-lactamases and numerous multidrug-efflux pumps. We also found the presence of several hemolysins genes, a complete flagellum system gene cluster and genes responsible for biofilm formation. Moreover, we reported for the first time in a clinical strain of Shewanella spp. the presence of a bacteriocin (marinocin). Conclusion: The WGS analysis of this pathogen provides insight into its virulence factors and resistance to antibiotics.  相似文献

Urinary incontinence is a common problem in older subjects, very often wrongfully accepted as a normal part of the aging process. A total of 520 subjects (208 males and 312 females; mean age 74.8 +/- 11.8 years), from both private- and nursing-home dwelling populations, were included in this study aimed to estimate the incidence of urinary incontinence and identify factors associated with condition, in aged subjects. The incidence and type of urinary incontinence (stress, urge or mixed incontinence) were assessed by structured questionnaires and diagnosis was confirmed by a seven-day consecutive voiding diary. Assessment of physical, cognitive and emotional functions was performed on each subject using the Mini Mental State Examination (MMSE), Instrumental Activities of Daily Living Scale (IADL), Tinetti Scale (gait), Tinetti Scale (balance) and Geriatric Depression Scale (GDS) instruments. In the total population sample the incidence of urinary incontinence was 47.9%. The incontinence cases were classified, according to the different types, as: stress incontinence (males: 3.4%; females: 8.7%; males+females: 6.5%); urge incontinence (males: 27.4%; females: 31.4%; males+females: 29.8%); mixed incontinence (males: 20.2%; females: 5.8%; males+females: 11.5%). In the total population sample, no significant relationship was found between age and prevalence of urinary incontinence. In the elderly female group, age significantly correlated in a direct manner with urge incontinence (P<0.01) and inversely with stress incontinence (P<0.001). Only in the male sex group age significantly correlated with mixed incontinence (P<0.005). Multiple linear regression analysis showed that the dependent variable 'incontinence' could be predicted by MMSE (P<0.001) in the male sex group and by the Tinetti Scale (gait) (P<0.001) in the female sex group.  相似文献

The parietal lobes contribute to body-space representation. The present work aims at characterizing the functional role of the inferior parietal lobe in body-space representation and at studying the different roles of the angular gyrus in the right and left hemisphere. We conducted three separate transcranial direct current stimulation (tDCS) experiments using “tactile distance task” as an implicit measure of body representation. Whereas anodal tDCS on the right angular gyrus influences vocal reaction times (vRT) for stimuli delivered on the ipsilateral body parts without changes of accuracy, right tDCS improved both vRT and accuracy for tactile stimuli on the contralateral limbs. Sham or left parietal anodal tDCS had no effect. These evidences support the view that right parietal areas have a crucial role in the metric component of the body representation.  相似文献
