A study to evaluate the efficacy and safety of Cefuroxime Axetil in enteric fever was carried out in 30 adult hospitalised patients of either sex. A positive blood culture for S. typhi and sensitivity to cefuroxime axetil were confirmed prior to treatment. On admission, the baseline signs and symptoms were recorded and treatment initiated with cefuroxime axetil in a dose of 500 mg bd; which was continued for 7 days after normalization of temperature. The various clinical parameters were followed up daily during the treatment period and discharge permitted on normalization of temperature. Blood culture for S. typhi was repeated 3 days after stopping treatment. Follow-up Widal, stool and urine cultures were done wherever possible to check for relapse or carrier state. All the patients responded clinically to treatment and had bacteriologically negative blood cultures by the end of 14 days treatment. 87% of the patients responded within 7 days of treatment of which 60% were graded as Excellent responders as they responded within 4 days itself; while 13% took a longer time to respond. There were no relapses or carrier state as indicated by negative follow-up stool cultures. Only one patient reported a side-effect of mild headache confirming the safety of the drug. We conclude that Cefuroxime axetil in a dose of 500 mg bd is an effective and safe drug in the treatment of multi drug resistant enteric fever. 相似文献

One possible mechanism that accounts for the alterations observed in varicose veins is the activation of endothelial cells by ischemia occurring in the leg veins during blood stasis and the cascade of reactions that follows. Because in vitro data suggest that endothelium alteration is a key event in the development of the pathology, it was important to confirm this hypothesis in patients. We used the number of circulating endothelial cells detached from the vascular wall as a criterion of the endothelium injury. We first compared the number of circulating endothelial cells (CECs) in patients with chronic venous insufficiency (CVI) with those of a control population. A twofold increase in the CEC count (1,001+/-127 CEC/ml of plasma compared with 514+/-82 CECs/ml) was observed in CVI patients, which indeed suggests an alteration of the endothelium in this disease. Second, the protective effect of a venotropic drug, Ginkgo biloba extract, troxerutine, and heptaminol (Ginkor Fort), was tested by a randomized double-blind, placebo-controlled clinical trial. In the active-treatment group, the mean values of the CEC count decreased by 14.5% after a 4-week treatment, whereas in the placebo group, the decrease was less (8.4%). The decrease from week 0 to the end of treatment was significantly higher in the active-treatment group than in the placebo group. These results confirm the important role of the endothelium alterations in the development of varicose veins and suggest a potential beneficial action of a venotropic drug on the venous wall. 相似文献

BACKGROUND: The value of antibiotics in acute rhinosinusitis is uncertain. Although maxillary sinusitis is commonly diagnosed and treated in general practice, no effectiveness studies have been done on unselected primary-care patients. We used a randomised, placebo-controlled design to test the hypothesis that there would be an improvement associated with amoxycillin treatment for acute maxillary sinusitis patients presenting to general practice. METHODS: Adult patients with suspected acute maxillary sinusitis were referred by general practitioners for radiographs of the maxillary sinus. Those with radiographic abnormalities (n = 214) were randomly assigned treatment with amoxycillin (750 mg three times daily for 7 days; n = 108) or placebo (n = 106). Clinical course was assessed after 1 week and 2 weeks, and reported relapses and complications were recorded during the following year. FINDINGS: After 2 weeks, symptoms had improved substantially or disappeared in 83% of patients in the study group and 77% of patients taking placebo. Amoxycillin did not influence the clinical course of maxillary sinusitis nor the frequency of relapses during the 1-year follow-up. Radiographs had no prognostic value, nor were they an effect modifier. Side-effects were recorded in 28% of patients given amoxycillin and in 9% of those taking placebo (p < 0.01). The occurrence of relapses was similar in both groups (21 vs 17%) during the follow-up year. INTERPRETATION: Antibiotic treatment did not improve the clinical course of acute maxillary sinusitis presenting to general practice. For these patients, an initial radiographic examination is not necessary and initial management can be limited to symptomatic treatment. Whether antibiotics are necessary in more severe cases warrants further study. 相似文献

The development of resistance among the bacterial pathogens causing acute otitis media and sinusitis in children is causing considerable concern. Although normally a mild infection, acute otitis media can produce serious complications with sequelae that can have long-lasting effects. High levels of resistance are now being seen in the three principal pathogens. Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis. Most clinical trials comparing the efficacy of different antibiotics have failed to show differences in clinical efficacy. To overcome this problem, alternative methods of assessing antibiotics have been developed including the "in-vivo sensitivity test" proposed by Howie and retrospective analyses of treatment failures. The treatment of sinusitis is complicated by the difficulty in establishing a clear differential diagnosis. To date, no definitive trials of bacteriologic efficacy in children have been published. 相似文献

Recently, it has been recognized that cell-bound heparan sulfate (HS) proteoglycans (HSPG) are able to bind and subsequently initiate degradation of lipoproteins. Two mediators of lipoprotein catabolism, both with HS binding capacity, lipoprotein lipase (LPL) and apolipoprotein E (apoE), are involved in this process. This mechanism is known as the secretion-capture process of apoE. Lipoprotein(a) [Lp(a)] was shown to have a strong binding capacity to cell-associated HSPG. This binding capacity was increased by LPL addition. We investigated the effects of recombinant apoE (r-apoE) enrichment of Lp(a) on the binding to HS. Lp(a), isolated by ultracentrifugation and gel filtration, was incubated with r-apoE and reisolated by ultracentrifugation, resulting in r-apoE-enriched Lp(a). ApoE-enriched Lp(a) and control Lp(a) were coated to microtiter plates. The capacity to bind biotin-conjugated HS (b-HS) in the presence or absence of inactivated bovine LPL was studied. R-apoE-enriched Lp(a) showed increased b-HS binding capacity versus control Lp(a). Addition of LPL resulted in an increased b-HS binding capacity of both control and r-apoE-enriched Lp(a). To investigate whether binding of Lp(a) to endothelial cell HSPG occurred in vivo, 39 volunteers were injected with heparin (50 U/kg) and plasma lipid and Lp(a) levels were determined before and 20 minutes after heparin injection. No significant increase in plasma Lp(a) concentrations was found. The results showed that Lp(a) can be enriched with apoE and that this resulted in increased LPL-enhanced binding to HSPG. From the in vitro studies, it can be concluded that the secretion-capture process of apoE is a possible catabolic route for Lp(a). However, whether this also occurs in vivo remains to be confirmed. 相似文献

Acute sinusitis is common and usually the result of edema around the sinus ostia from the common cold. Chronic sinusitis and recurrent sinusitis are common complications of untreated or undertreated infection. Serious and life-threatening complications are uncommon but demand a high index of suspicion, accurate diagnosis, and rapid intervention by medical and surgical methods. Immediate parenteral administration of antibiotics may be necessary to prevent permanent disabilities or death, and early consultation with an otolaryngologist or neurosurgeon is prudent. Computed tomography is the imaging method of choice for detection of serious intracranial complications of acute sinusitis. Increasing numbers of immunocompromised patients and seriously ill hospitalized patients with problems related to complications of acute sinusitis are being seen. 相似文献

Brodimoprim, a new dehydrofolate reductase inhibitor, was compared with cephalexin in the treatment of patients with acute sinusitis. A total of 49 patients were randomly assigned to receive either brodimoprim 200-mg tablets once a day (400 mg on the first day as a loading dose) or cephalexin 500-mg tablets three times a day for 8 to 12 days. Nearly all patients treated were judged clinically cured/improved; in fact, only one failure (in the cephalexin group) was noted. In the 45 assessable patients, the time until disappearance of the symptoms and the duration of treatment did not differ significantly between the two groups. A bacteriologic examination was performed in all patients at baseline as well as at the end of therapy. Bacteriologic eradication was obtained in 88% of the patients treated with brodimoprim and in 76% of those receiving cephalexin. Both compounds were generally well tolerated (one patient in the brodimoprim group complained of skin reactions). These results suggest that once-daily treatment with brodimoprim represents safe and effective therapy for adults with acute bacterial sinusitis. 相似文献

The introduction of cranial radiotherapy (CRT) has provided efficient control of overt or subclinical meningeosis in acute leukemia. Especially due to the long-term toxicity of CRT, reduction or elimination of radiotherapy appeared mandatory after cure rates of more than 70% had been achieved in acute lymphoblastic leukemia (ALL). Several large clinical trials of the Berlin-Frankfurt-Münster (BFM) Study Group with more than 3500 patients since 1981 have demonstrated that intensive systemic and intrathecal chemotherapy without or with limited CRT can efficiently prevent central nervous system (CNS) relapses in a large percentage of patients. However, only in low-risk patients prophylactic radiotherapy can be completely and safely replaced by conventional doses of methotrexate. In addition, reduction of chemotherapy in low-risk ALL increased the rate of relapses with CNS involvement. Thus, only a combination of multidrug induction, high-dose methotrexate (HD-MTX) consolidation, and reintensification allowed safe elimination of CRT in low-risk ALL. This approach combined with CRT with 12Gy and 18 Gy in medium and high risk ALL, respectively, reduced the incidence of relapses with CNS involvement to less than 5% (trial ALL-BFM 86). Patients with inadequate response to therapy, or with T-cell ALL, or with overt CNS disease are at particularly high risk for relapse with CNS involvement, and require more systemic and intrathecal chemotherapy combined with cranial irradiation. In B-cell ALL, short intensive chemotherapy pulses including HD-MTX could completely replace radiotherapy. In AML, post-consolidation CRT appears to be advantageous with regard to control of extramedullary as well as systemic relapses. 相似文献

Effect of sodium hypochlorite disinfection of impressions on the size and quality of plaster models is studied. Twenty-minute submerging of silicone impressions in 0.5% sodium hypochlorite solution did not change their size and did not deteriorate the quality of surface and hardness of plaster models. Stomalgin impressions cannot be disinfected by sodium hypochlorite solution because of expressed destructive effect of this disinfectant on the impressions. 相似文献

The purpose of the investigation was to examine the diagnostic value of various symptoms, clinical findings, erythrocyte sedimentation rate (ESR) and serum C-reactive protein (CRP) in acute maxillary sinusitis using the aspiration of purulent or mucopurulent from the sinus of a patient with a pathological CT-scanning as the golden standard. Of 174 patients with suspected acute maxillary sinusitis seen in general practice we found 70% to have a pathological CT-scanning and 53% to have pus or mucous pus in the sinus aspirate. Only the ESR and CRP level were found to be significantly and independently associated with a positive diagnosis as defined by the golden standard. A clinical criterion based on either an elevated ESR and/or CRP level in a patient with pain related to the maxillary sinus region had sensitivity of 0.82, a specificity of 0.57, a positive predictive value of 0.68 and a negative predictive value of 0.75, and was diagnostically superior to the clinical examination. The investigation also confirms that this disease is most likely overdiagnosed in general practice. 相似文献

The effects of Vitamin E administration on antioxidant enzyme activities and nitrite-nitrate levels of the reperfused rat kidney tissues were investigated by performing a 60 min ischemia followed by 24 and 72 hours of reperfusion. Vitamin E administration or the placebo (SF) was applied as 100 mg/kg BW. As expected, catalase (CAT) (p<0.05) and superoxide dismutase (SOD) (p<0.05) activities of ischemia/reperfused (I/R) kidney tissue were lower and malondialdehyde (MDA) levels were higher than control kidneys in both SF and vitamin E treated groups following 24 h reperfusion. During reperfusion of long term (72 h), vitamin E triggered a decrease in the MDA levels in the ischemic tissue, while it did not provoke a significant effect on SOD and catalase activities. Total nitrite levels of ischemic tissues in both of the groups were higher than matched control kidneys and this elevation was more clear in the vitamin E treated group. Our results showed that vitamin E has a protective effect on I/R injury, by a direct chain breaking effect on lipid peroxidation (LPO) and hence preventing the nitric oxide (NO) reservoir of ischemic tissue. Alfa-tocopherol may be a promising agent for the prevention of tissue injury caused by free oxygen radicals. 相似文献

Local application of hydrogels based on the sorbent regencur with dioxidine was tried for efficacy against chronic purulent maxillary sinusitis in 30 patients versus matched controls. Changes in the subjective and objective manifestations of the disease were registered on the sensor-analog and visual-analog scales. The findings indicate higher efficacy of regencur hydrogels with dioxidine. 相似文献

Gastroenteritis in children is usually treated with the graded introduction of milk feeds after rehydration. Although having never been rigorously tested, the practice of gradually increasing milk strength over several days has been considered an appropriate means of warding against lactose intolerance and preventing sensitization to cow's milk antigens. These guidelines were formulated in Europe and North America and invariably lead to a reduction in nutrient intake. Malnourished children in developing countries, however, may experience an average 5-6 episodes of acute diarrhea per year and the nutrient effects are cumulative. A recent study from Latin America explored whether continued feeding is safe for infants under age 6 months and whether malnourished children respond adversely. Infants randomly assigned to receive full strength cow's milk immediately after rehydration did not have more treatment failures, higher stool outputs, or longer lasting diarrhea than those whose feeds were regarded to full strength over 48 hours. It is unclear, however, whether the youngest or more malnourished subjects were overrepresented in the treatment failures. Results also indicate that deciding to change treatment should not be dictated by the presence of reducing substances in the faeces; the majority of infants with reducing substances in their stools did well. This study offers the first scientific support for rapidly reintroducing full-strength milk formula after gastroenteritis is malnourished patients under 6 months of age. The 10% of infants in which dehydration recurs after reintroducing milk feeds are still difficult to manage. In the absence of yogurt or lactose-free formula, a locally-produced modular feed of chicken, starch, and vegetable oil may be suitable. 相似文献
