The purpose of this study was to determine the microbiological profile of diabetic foot infections (DFIs) and assess the antibiotic susceptibility of the causative agents. Data were obtained from a retrospective analysis of DFI samples collected from June 2007 to July 2008. Specimens were cultured using optimal aerobic and anaerobic microbiological techniques, and antibiotic susceptibility testing was performed according to the methods recommended by the Clinical and Laboratory Standards Institute (CLSI). Extended-spectrum β-lactamase (ESBL) production was measured using the double disk synergy test and the ESBL Etest. A total of 440 patients were diagnosed with DFIs during this period, and a total of 777 pathogens were isolated from these patients with an average of 1.8 pathogens per lesion. We isolated more Gram-negative pathogens (51.2%) than Gram-positive pathogens (32.3%) or anaerobes (15.3%). Polymicrobial infection was identified in 75% of the patients. The predominant organisms isolated were members of the Enterobacteriaceae family (28.5%), Pseudomonas aeruginosa (17.4%), Staphylococcus aureus (11.8%), methicillin-resistant S. aureus (7.7%), anaerobic Gram-negative organisms (10.8%), and Enterococcus spp. (7%). Vancomycin was the most effective treatment for Gram-positive bacteria, and imipenem, piperacillin-tazobactam and amikacin were the most effective treatments for the Gram-negative bacteria. In conclusion, DFI is common among diabetic patients in Kuwait, and most of the cases evaluated in this study displayed polymicrobial etiology. The majority of isolates were multi-drug resistant. The data gathered in this study will be beneficial for future determinations of empirical therapy policies for the management of DFIs.
We studied whether tramadol administered at the time of wound closure can prevent postanaesthetic shivering. One hundred and fifty patients scheduled for general anaesthesia and surgery were randomly allocated and tramadol was administered intravenously at a dose of 2 mg.kg(-1) in the high-dose group, 1 mg.kg- in the low-dose group and 0.9% saline in the control group. In the high-dose group, 2% of patients had postanaesthetic shivering, compared to 4% in the low-dose group and 48% in the control group (p < 0.001 vs. tramadol groups). There was no delay in tracheal extubation after reversal of neuromuscular blockade. The incidence of adverse side-effects such as sedation and vomiting did not differ statistically and were clinically not significant. This study strongly supports the use of tramadol at wound closure for prevention of postanaesthetic shivering.
Objectives: To determine the microbiological profile of breast abscess and assess the antibiotic susceptibility of the causative agents. Materials and Methods: Data obtained from cases of breast abscess over a period of 3.5 years, June 2006 to December 2009, were retrospectively analyzed. Specimens were cultured using optimal aerobic and anaerobic microbiological techniques. The antibiotic susceptibility test was carried out using the methods recommended by the Clinical and Laboratory Standards Institute. One specimen per patient was analyzed. Results: Of the 114 patients, 107 (93.8%) non-lactating and 7 (6.1%) lactating women were diagnosed with breast abscess during this period. Of the 114 specimens, 83 (73%) yielded bacterial growth. Of these, 115 pathogens were isolated with an average of 1.4 pathogens per abscess. Eighteen (22%) of the 83 specimens yielded mixed bacterial growth. There were more Gram-positive pathogens (60, 52%) than anaerobes (32, 28%) and Gram-negative pathogens (22, 19%). The predominant organisms were methicillin-susceptible Staphylococcus aureus (37, 32%), methicillin-resistant S. aureus (MRSA; 11, 10%), Bacteroides spp. (16, 14%), anaerobic streptococci (14, 12%) and Pseudomonas aeruginosa (9, 8%). Of the 48 S. aureus, MRSA accounted for 11 (23%). All MRSA isolates were susceptible to trimethoprim-sulfamethoxazole and vancomycin. Conclusion:S. aureus was the most common pathogenic organism isolated in breast abscesses at Al-Amiri Hospital, Kuwait, of which 23% were MRSA. Nearly a third of the cases were caused by anaerobes, particularly B. fragilis. The data present a basis for the formation of empirical antimicrobial therapeutic policy in the management of breast abscess.
A woman presented with erythema nodosum followed by bilateral breast abscesses without a gastrointestinal manifestation, due to a rare serotype of Salmonella , namely, Salmonella enterica serotype Poona. This is the first reported case of erythema nodosum presumably associated with Salmonella infection without a gastrointestinal manifestation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
