The!Northern!Ohio!Foot!and!Ankle!Journal!!! ! ! ! !!!!!!!!!Official!Publication!of!the!NOFA!Foundation! ! A literature review of Pseudomonas aeruginosa infection and the appropriate regimen of antibiotics whether Combination antibiotic therapy or monotherapy. by Hazim Ibrahim DPM 1 The Northern Ohio Foot and Ankle Journal Abstract: Pseudomonas aeruginosa is a common cause of gram-negative infection, especially in patients with compromised host defense mechanisms. It is the most common pathogen isolated from patients who have been hospitalized longer than 1 week, and it is a frequent cause of nosocomial infections. Pseudomonas infections are complicated and can be life-threatening. The choice of antibiotic monotherapy or combination therapy to treat Pseudomonas aeruginosa bacteremia is controversial. The aim of this review is to discuss the infection by pseudomonas with its characteristics and to compare both types of therapy to determine which delivers the best outcome for P. aeruginosa bacteremia. Neither combination therapy nor monotherapy treatment appears to have a significant effect on mortality rates in patients with P. aeruginosa bacteremia. Further studies evaluating the effects of combination therapy or monotherapy in more specialized cases, such as when encountering a multidrug-resistant organism, are necessary.

Moreover, studies have not specifically examined the Combination empirical antimicrobial therapy directed effect of administering combination antimicrobial against Gram-negative bacteria may be a more agents [9,10].

    Read Ebook {PDF EPUB} Pseudo by dysonrules Pseudoreplication: choose your data wisely¶ Many studies strive to collect more data through replication: by repeating their measurements with additional patients or samples, they can be more certain of their numbers and discover subtle relationships that aren’t obvious at first glance. We’ve seen the value of additional data for improving statistical power and detecting small differences. But what exactly counts as a replication? Let’s return to a medical example. I have two groups of 100 patients taking different medications, and I seek to establish which medication lowers blood pressure more. I have each group take the medication for a month to allow it to take effect, and then I follow each group for ten days, each day testing their blood pressure. I now have ten data points per patient and 1,000 data points per group. Brilliant! 1,000 data points is quite a lot, and I can fairly easily establish whether one group has lower blood pressure than the other. When I do calculations for statistical significance I find significant results very easily. But wait: we expect that taking a patient’s blood pressure ten times will yield ten very similar results. If one patient is genetically predisposed to low blood pressure, I have counted his genetics ten times. Had I collected data from 1,000 independent patients instead of repeatedly testing 100, I would be more confident that differences between groups came from the medicines and not from genetics and luck. I claimed a large sample size, giving me statistically significant results and high statistical power, but my claim is unjustified.

Serological and pyocin typing was performed on 152 isolates, and serological type 1 was found to be the most prevalent (34.2%). Pyocin typing was found to be the most efficient method of differentiation, although serological typing was more practical. A comparison of the total number of positive ~· aeruginosa samples fran each sample type showed that this pseudomonad was most commonly isolated fran sediment samples.

  • Yellow Nail Syndrome: a Review Stéphane Vignes1* and Robert Baran2
    Vignes and Baran Orphanet Journal of Rare Diseases (2017) 12:42 DOI 10.1186/s13023-017-0594-4 REVIEW Open Access Yellow nail syndrome: a review Stéphane Vignes1* and Robert Baran2 Abstract Yellow nail syndrome (YNS; OMIM 153300, ORPHA662) is a very rare disorder that almost always occurs after 50 years of age but a juvenile or familial form has also been observed. YNS is diagnosed based on a triad associating yellow nail discoloration, pulmonary manifestations (chronic cough, bronchiectasia, pleural effusion) and lower limb lymphedema. Chronic sinusitis is frequently associated with the triad. YNS etiology remains unknown but a role of lymphatic impairment is usually evoked. YNS is more frequently isolated but may be associated in rare cases with autoimmune diseases, other clinical manifestations implicating lymphatic functions or cancer and, hence, is also considered a paraneoplastic syndrome. YNS management is symptomatic and not codified. YNS can resolve spontaneously. Oral vitamin E alone or even better when associated with triazole antifungals may achieve partial or total disappearance of nail discoloration. Pleural effusion can be treated surgically, with decortication/pleurectomy or pleurodesis. Antibiotic prophylaxis is prescribed for bronchiectasia with chronic sputum production. Lymphedema treatment is based on low-stretch bandages and the wearing of elastic compression garments combined with skin care, exercises and, as needed, manual lymph drainage.
