A population based hybrid design combining element of cohort and cross-sectional approach was used to develop a simple clinical algorithm to predict individual probability of developing hypertension (systolic BP > 140 mm Hg and/or diastolic BP > 90 mmHg). 3615 soldiers initially normotensive at the time of induction into high altitude, were studied by systematic random sampling. Multiple logistic regression analysis showed a high significant association between hypertension and age, body mass index (BMI), tobacco smoking and alcohol consumption. Using the constant/coefficient values obtained from the logistic model and the receiver operating characteristics (ROC) curve analysis, the following predictive rule was developed – To the age in years, add (BMIx 3.86); also add 5.53 if he is a smoker; and add 19.81 if he consumes alcohol. If the total exceeds 142, the individual is at high risk of developing hypertension. This algorithm carries a sensitivity of 68.2% and specificity of 78.5%.KEY WORDS: Hypertension, High altitude 相似文献

Two-hundred and eighty bacterial isolates from wound and soft tissue infections were studied for species identification and antibiotic resistance pattern. Amongst them 122 isolates were from community acquired infection and 158 were from nosocomial infections. The common community acquired pathogens were Staphylococcus aureus (67.8%) and Streptococcus pyogenes (10.7%), whereas Staphylococcus aureus (60.1%) and E. Coli (8.9%) were common in nosocomial infection. Only two anaerobes (Cl perfringens) were isolated. Penicillin resistance was found to be 87% and 92% for Staphylococccus aureus in community acquired and noscomial infections respectively. 85% of Proteus isolates were resistant to ampicillin. There was relatively lower level of resistance by all isolates to cefotaxime. Gentamicin showed higher rate of resistance than netilmicin and amikacin. Resistance of E. coli isolates to fluoroquinolones being 79% for norfloxacin, 81% for ciprofloxacin and 60% for ofloxacin. The study showed a higher resistance of methicillin resistant Staphylococcus aureus (MRSA) to other antibiotics. Amikacin and ofloxacin were the best recommended drugs for empirical therapy for all organisms, the susceptibility rate being 80.7% and 80.4%.KEY WORDS: Antibiotic resistance, Soft tissue infections, Wound infections 相似文献

India is home to a large patient population of both rheumatoid arthritis (RA) and tuberculosis (TB). As the usage of biologic agents in RA increases in India, the issue of TB reactivation and prophylaxis becomes very pertinent. The consensus view of an expert group from the Indian Rheumatology Association is presented. Tuberculin testing has limited utility in India and isoniazid prophylaxis seems to be a reasonable option. It is hoped that this report shall pave the way for formal guidelines. 相似文献

Abstract Ascitic fluid total protein, albumin, cholesterol, their ascites/serum ratios, serum-ascites albumin and cholesterol gradients were measured for their ability to differentiate cirrhotic, malignant and tuberculous ascites in 76 patients. The mean ± s.d. ascitic fluid total protein, albumin, cholesterol, their respective ascitic fluid/serum ratios in cirrhotic ascites were lower than malignant and tuberculous groups ( P < 0.001 for each). The difference between malignant and tuberculous groups was significant for ascitic fluid/serum total protein ( P < 0.05) and ascitic fluid/serum albumin ( P < 0.01) only. Mean serum-ascites albumin gradient in cirrhotics was higher than in the malignant and tuberculous groups ( P < 0.001 for each). The difference between malignant and tuberculous groups was significant ( P < 0.01). Mean ± s.d. serum-ascites cholesterol gradient in cirrhotics was higher than that in malignant and tuberculous groups ( P < 0.001 for each). The difference between malignant and tuberculous groups was also significant ( P < 0.01). Both serum/ascitic fluid total protein less than 0.5 and ascitic fluid cholesterol less than 55 mg/dL had 94% diagnostic accuracy for differentiating cirrhotic from malignant and tuberculous ascites. Serum ascitic fluid albumin gradient greater than 1.1 g/dL, ascitic fluid/serum albumin less than 0.65 and ascitic fluid albumin less than 2 g/dL had diagnostic accuracy of 92, 92 and 91%, respectively. Ascitic fluid total protein had diagnostic accuracy of 88%. None of the tests was able to differentiate between malignant and tuberculous ascites. Measurement of ascitic fluid cholesterol concentration is a simple method of differentiating cirrhotic from non-cirrhotic ascites. 相似文献

TOPICAL PHENYTOIN IN WOUND HEALING 总被引:1,自引:0,他引:1
ARVIND K. PENDSE M.S. AKHILESH SHARMA M.B. B.S. ASHA SODANI M.B. B.S. SUMAN HADA M.B. B.S. 《International journal of dermatology》1993,32(3):214-217
Background. Phenytoin, introduced in 1937 as an antiseizure medication, has since been reported to promote wound healing when applied as a topical agent. This study was undertaken to evaluate its effectiveness in chronic skin ulcers. Methods. Seventy-five inpatients with chronic skin ulcers were included in this controlled trial. Forty patients were treated with topical phenytoin, and 35 patients with conventional saline dressings. Assessment of the wounds included wound area, bacteriologic cultures, and clinical assessment by blind observers at baseline and every 7 days thereafter over the 4-week treatment period. Results. Wound area reduction was greater in the phenytoin group than in controls. Fifty percent of phenytoin-treated wounds had negative cultures by day 7, compared to 17% of controls. Healthy granulation tissue appeared earlier with phenytoin. At the end of the fourth week, 29 of 40 phenytoin-treated ulcers had healed completely versus 10 of 35 controls. Conclusions. Topical phenytoin appears to be an effective, inexpensive, and widely available therapeutic agent In wound healing. Further clinical use and evaluation is merited. 相似文献

Abstract Loeffler's methylene blue, commonly used as a counter-stain for acid fast bacilli, was used to detect Helicobacter pylori in paraffin sections and touch smears of gastric mucosal biopsies from 15 patients with duodenal ulcer and 35 with non-ulcer dyspepsia, and the results were compared with the modified Giemsa stain. The time taken to stain smears by Loeffler's methylene blue was approximately 10 min and the results correlated well with those stained by the modified Giemsa stain. However, the Loeffler's methylene blue method was found to be simpler, quicker and cheaper than the modified Giemsa stain. 相似文献

We have measured plasma levels of somatomedin-C, one of the principal mediators of growth hormone action, in 25 patients with plaque-type psoriasis of varying severity and compared these levels with those found in healthy controls. Plasma somatomedin-C levels were not elevated in the psoriatic patients regardless of the severity of their disease, suggesting that in these patients growth hormone secretion is within normal limits. 相似文献

Abstract— The effects of ethanol alone and in combination with sulphanilyl fluoride on some of the antioxidant defences in the stomach of rats have been examined. These effects were correlated with lesion formation in the gastric mucosa. Oral administration of ethanol induced gastric lesions which were prevented by sulphanilyl fluoride pre-treatment. N-Ethylmaleimide antagonized the anti-lesion action of sulphanilyl fluoride. Ethanol administration lowered the glucose-6-phosphate dehydrogenase activity in the gastric mucosa, an effect potentiated by N-ethylmaleimide pre-treatment. The total superoxide dismutase activity was unaffected by the drugs used in the present study. Ethanol, however, markedly increased mucosal catalase activity which was reduced by sulphanilyl fluoride pretreatment and reversed by N-ethylmaleimide. It is concluded that the ulcerogenic mechanism of ethanol is mediated at least in part by the depression of the hexose monophosphate shunt and the production of active oxygen species, whereas the anti-lesion action of sulphanilyl fluoride is probably not mediated through these mechanisms. 相似文献

Background. When multidrug therapy was introduced a decade ago to shorten the duration of treatment, paucibacillary leprosy was advocated 6 months of treatment. The diagnosis is based mainly on clinical and histopathologic examination, negative slit-skin smear examination, and positive lepromin test. Methods. The case records of 508 paucibacillary leprosy patients attending our urban leprosy center have been analyzed with reference to regularity of therapy, response to multidrug regimen, follow-up, and relapse. Results. The incidence of paucibacillary leprosy was found to be 37%. Defaulter rate was 45%. Nine percent of the cases attended the center with deformities emphasizing the need for corrective surgery and early case detection to prevent them. Conclusions. The main problem that we faced was the optimum duration of treatment, which is as yet an unsettled question. The opinions of other workers have been given, and a slight modification in current WHO regimen has been suggested without significantly affecting the cost of therapy. 相似文献
