Extraction and analysis of cosmetic active ingredients from an anti-cellulitis transdermal delivery system by high-performance liquid chromatography.
(1/320)
A new transdermal delivery system that controls cellulitis is evaluated using reversed-phase high-performance liquid chromatography coupled with photodiode array detection. An extraction procedure and the validation of the analytical method to assay the active excipients from the Centella asiatica plant (asiaticoside, madacessic acid, and asiatic acid) are described. Excellent results ae obtained in terms of linearity, accuracy, and specificity of the analytical method. (+info)
Fulminant meningococcal supraglottitis: An emerging infectious syndrome?
(2/320)
We report a case of fulminant supraglottitis with dramatic external cervical swelling due to associated cellulitis. Blood cultures were positive for Neisseria meningitidis. The patient recovered completely after emergency fiberoptic intubation and appropriate antibiotic therapy. We summarize five other cases of meningococcal supraglottitis, all reported since 1995, and discuss possible pathophysiologic mechanisms. (+info)
Risk factors for erysipelas of the leg (cellulitis): case-control study.
(3/320)
OBJECTIVE: To assess risk factors for erysipelas of the leg (cellulitis). DESIGN: Case-control study. SETTING: 7 hospital centres in France. SUBJECTS: 167 patients admitted to hospital for erysipelas of the leg and 294 controls. RESULTS: In multivariate analysis, a disruption of the cutaneous barrier (leg ulcer, wound, fissurated toe-web intertrigo, pressure ulcer, or leg dermatosis) (odds ratio 23.8, 95% confidence interval 10.7 to 52.5), lymphoedema (71.2, 5.6 to 908), venous insufficiency (2.9, 1.0 to 8.7), leg oedema (2.5, 1.2 to 5.1) and being overweight (2.0, 1.1 to 3.7) were independently associated with erysipelas of the leg. No association was observed with diabetes, alcohol, or smoking. Population attributable risk for toe-web intertrigo was 61%. CONCLUSION: This first case-control study highlights the major role of local risk factors (mainly lymphoedema and site of entry) in erysipelas of the leg. From a public health perspective, detecting and treating toe-web intertrigo should be evaluated in the secondary prevention of erysipelas of the leg. (+info)
Staphylococcus intermedius cellulitis and toxic shock in a dog.
(4/320)
A Labrador retriever was examined for sudden lameness and cellulitis of the right forelimb. Bacterial culture of the dermis yielded a large number of Staphylococcus intermedius. The association of this bacterium with toxic shock is discussed. (+info)
Persistent Bacillus licheniformis bacteremia associated with an international injection of organic drain cleaner.
(5/320)
In recent years manufacturers have developed several products containing saprophytic bacteria, previously believed to be of minimal pathogenicity. We describe the first case of persistent Bacillus licheniformis bacteremia occurring after intentional injection of a consumer product that includes B. licheniformis spores. We postulate that these spores remained in the tissue, unaffected by antimicrobials, ultimately necessitating soft-tissue debridement of the area surrounding the injection site. On the basis of this case and a review of the literature, we submit that some consumer products contain bacteria with demonstrated pathogenicity. Manufacturers should study these bacteria in detail in order to rapidly provide information such as bacteriologic data and antimicrobial susceptibility data to clinicians. (+info)
Cost-effectiveness of blood cultures for adult patients with cellulitis.
(6/320)
To assess the cost-effectiveness of blood cultures for patients with cellulitis, a retrospective review was conducted of clinical and microbiological data for all 757 patients admitted to a medical center because of community-acquired cellulitis during a 41-month period. Blood cultures were performed for 553 patients (73%); there were a total of 710 blood samples (i.e., a mean of 1.3 cultures were performed per patient). In only 11 cases (2.0%) was a significant patient-specific microbial strain isolated, mainly beta-hemolytic streptococci (8 patients [73%]). An organism that was considered a contaminant was isolated from an additional 20 culture bottles (3. 6%). The cost of laboratory workup of the 710 culture sets was $36, 050. Isolation of streptococci led to a change from empirical treatment with cefazolin to penicillin therapy for 8 patients. All patients recovered. In conclusion, the yield of blood cultures is very low, has a marginal impact on clinical management, and does not appear to be cost-effective for most patients with cellulitis. (+info)
High prevalence of abscesses and cellulitis among community-recruited injection drug users in San Francisco.
(7/320)
The prevalence of and risk factors for abscesses and cellulitis were investigated among a community sample of injection drug users (IDUs). Participants were interviewed, and those with symptoms were examined. Of 169 IDUs, 54 (32%) had abscesses (n=35), cellulitis (n=5), or both (n=14); 27% had lanced their own abscesses; and 16% had self-treated with antibiotics they purchased on the street. IDUs who skin-popped (injected subcutaneously or intramuscularly) were more likely to have an abscess or cellulitis than those who had injected only intravenously (odds ratio, 4.9; 95% confidence interval, 2.2-11). The likelihood of abscesses and cellulitis increased with frequency of skin-popping and decreased with increasing duration of injection drug use. Abscesses are extremely prevalent among IDUs in San Francisco. Skin-popping is a major risk factor, and self-treatment is common. (+info)
Management and morbidity of cellulitis of the leg.
(8/320)
Ascending cellulitis of the leg is a common emergency. An audit was conducted in two district general hospitals to determine how it is managed and the long-term morbidity, and to formulate a treatment strategy. Case notes were reviewed for 92 patients admitted to hospital under adult specialties. Mean duration of inpatient therapy was 10 days. A likely portal of entry was identified in 51/92 cases, of which the commonest were minor injuries and tinea pedis. Pathogens were rarely identified, group G streptococci being the single most frequent organism. Benzylpenicillin was administered in only 43 cases. Long-term morbidity, identified in 8 of 70 patients with over six months' follow-up, included persistent oedema (6) and leg ulceration (2); an additional 19 patients had either suffered previous episodes or experienced a further episode subsequently. Ascending cellulitis of the leg has substantial short-term and long-term morbidity. Important but often neglected therapeutic suggestions are the inclusion of benzylpenicillin in all cases without a contraindication, assessment and treatment of tinea pedis, use of support hosiery, and serological testing for streptococci to confirm the diagnosis in retrospect. The high frequency of recurrent episodes suggests that longer courses of penicillin, or penicillin prophylaxis, might be useful. (+info)
