Wound infection

Polydioxanone (PDS) is completely elirninated from the body upon absorption. The mechanism of polydioxanone degradation is similar to that observed for other synthetic bioabsorbable polymers. Polydioxanone degradation in vitro was affected by gamma irradiation dosage but not substantially by the presence of enzymes (39). The strength loss and absorption of braided PDS, but not monofilament PDS, implanted in infected wounds, however, was significantly greater than in noninfected wounds. 

Chloramine-T, sodium A/-chloro-/)-toluenesulfonamide [127-65-17, was widely used during World War I for the treatment of infected wounds, and subsequentiy for hygienic purposes such as mouthwashes, douches, etc. It can be used for sanitising food-handling equipment, but its activity is considerably slower than that of hypochlorites. The Grade A Pasteurized Milk Ordinance (1985) and the Ordinance and Code for Restaurants (1948) of the U.S. Pubhc Health Service permitted the use of chloramine-T. 

Botulism is a disease caused by ingestion of foods contaminated with Clostridium botulinum (food-borne botulism) or, very rarely, by wound infection (wound botulism) or colonization of the intestinal tract with Clostridium botulinum (infant botulism). The toxins block the release of acetylcholine. Botulism is characterized by generalized muscular weakness, which first affects eye and throat muscles and later extends to all skeletal muscles. Flaccid paralysis can lead to respiratory failure. 

Abseesses formed by streptoeoeei and staphyloeoeei ean be deep seated in soft hssues or associated with infected wounds or skin lesions. These beeome loealized through the deposition of fibrin eapsules around the infeehve site. Fibrin deposihon is... 

The acridine dyes, including proflavine, acriflavine and aminacrine, have also been employed for skin disinfection and treatment of infected wounds or burns. They are slow-acting and mainly bacteriostatic in effect, with no useful fungicidal or sporicidal... 

Phenazines — This large class of compounds includes more than 6,000 natural and synthetic representatives. Natural phenazines are secondary metabolites of certain soil and marine microorganisms. The main phenazine producers are Pseudomonas and Streptomyces species. Pseudomonas strains produce the most simple phenazines tubermycin B (phenazine-1-carboxylic acid), chlororaphine, pyocyanin, and iodinine. Pyocyanin is a blue pigment while chlororaphine is green both are produced by Pseudomonas aeruginosa. They can be seen in infected wounds of animal and human skins. Iodinine is a purple phenazine produced by Pseudomonas aureofaciens. 

The pathogenesis of diabetic foot infection stems from three key factors neuropathy, angiopathy, and immunopathy. Aerobic gram-positive cocci, such as S. aureus and P-hemolytic streptococci, are the predominant pathogens in acutely infected diabetic foot ulcers. However, chronically infected wounds are subject to polymicrobial infection and require treatment with broad-spectrum antibiotics. 

Erythema, edema, and purulent or malodorous drainage at the wound site are manifestations of infected wounds. The patient may be febrile. 

Two cases have been selected here to illustrate the targeting of pathologically overexpressed enzymes, namely peptidases overexpressed in infected wounds and in tumors. 

Like other semisynthetic penicillins, methicillin exhibits an antibacterial effect similar to that of benzylpenicillin. The main difference between methicillin and benzylpenicillin is that it is not inactivated by the enzyme penicillinase, and therefore it is effective with respect to agents producing this enzyme (staphylococci). It is used for infections caused by benzylpenicillin-resistant staphylococci (septicemia, pneumonia, empyemia, osteomyelitis, abscesses, infected wounds, and others). Synonyms of this drug are cinopenil, celbenin, staphcillin, and others. 

Cefalotin is used for bacterial infections of the lower respiratory tract, urinary tract, skin, soft tissues, bones and joints, sepsis, peritonitis, osteomyelitis, mastitis, infected wounds, and post-operational infections. Synonyms of this drag are ceflin, seffein, coaxin, and others. 

It is used for peritonitis, sepsis, meningitis, cholangitis, empyema of the gaU bladder, pneumonia, lung abscesses, pyelonephritis, infections of the bones, joints, skin, soft tissues, abdominal and gynecological infections, and for infected wounds and bums. The main synonym of this drug is rocefm. 

It is used for various gastrointestinal diseases caused by microorganisms sensitive to it, including enteritis, which is caused by microbes that are resistant to antibiotics. However, because of its high oto- and nephrotoxicity, its local use is preferred for infected skin diseases, infected wounds, conjunctivitis, keratitis, and others. Synonyms of this drug are framycetin, soframycin, tautomycin, and others. 

It is used for treating sepsis, meningitis, osteomyelitis, periotonitis, pneumonia, pyelonephritis, pyelocystitis, infected wounds, and post-operational purulent complications caused by microorganisms sensitive to the drug. Synonyms of this drug are karmycin, kamaxin, resistomycin, and many others. 

It is used for pyelonephritis, cystitis, pneumonia, pleural empyema, peritonitis, sepsis, meningitis, purulent skin and soft tissue infections, infected wounds, bums, and so on, which are caused by microorganisms that are sensitive to the dmg. Gentamicin is the dmg of choice for severe bacterial infections caused by undetermined stimuli. Synonyms of this drug are garamycin, gentacylin, ribomycin, and many others. 

For debridement of necrotic tissue and liquefication of slough in acute and chronic lesions such as pressure ulcers, varicose, diabetic, and decubitus ulcers, burns, postoperative wounds, pilonidal cyst wounds, carbuncles, and miscellaneous traumatic or infected wounds. Also stimulates vascular bed activity to improve epithelization. 

Colombia. The Witotos and Boras used the fresh leaf as poultice over boils and infected wounds. The Tikuna men mix the crushed leaves with oil from palms and used as a hair treatment to prevent baldness. The juice is taken orally by the Tukanos to induce vomiting and narcosis . 

Peru. Decoction of the leaf with ayahuasca beverage (Banisteriopsis caapi and Psychotria viridis) is taken orally for hallucinating effect during shamanic training. A diet of cooked plantain and smoked fish follows each use . Hot water extract of the dried flower and leaf is used externally for snake and spider bites . The Witotos and Boras used the fresh leaves as poultice over boils and infected wounds. The Tikuna men mix the crushed leaves with oil from palms as a hair dressing to prevent baldness.

Cytochemical identification of peroxidase was conducted in infected wound margins in the cell walls and degenerating cytoplasm of wheat leaves with 3,3 -diaminobenzidine (Thorpe and Hall, 1984). The same substrate... 

In practice, further important aspects of BC are the focus of interest, concerning cooling of overtaxed muscles and particularly wound treatment of animals such as horses, sheep, cows, cats, and dogs. Extremely highly infected wounds are frequent in dogs after car crashes or similar accidents [143]. Furthermore, treatment of badly healing and permanent wounds, e.g., ulcers, and in the clinical and home-care sector both for human and veterinary medicine, as well as specific applications in tissue engineering will be major future developments. 

Folklore is rich in references to the healing properties of urea. The Babylonians of about 800 b.c. are known to have used it. In the beginning of this century, urea was employed in the treatment of infections, particularly infected wounds and ulcers, infection of the ears, infected tooth sockets, infected malignant growths, and of burns.4,5... 

Although the aminoglycosides such as streptomycin, neomycin and the gen-tamicins have a long and storied history as treatments for antibacterial infections, particularly in the early days when streptomycin was a treatment for both infected wounds and also for tuberculosis, few modifications of the basic molecule(s) went into clinical use, mainly due to the complexity of chemical modification of saccharidic-based structures. Thus, we do not discuss this class further or molecules such as the rifamycins and their manifold derivatives. Instead, due to space constraints, we show how p-lactams,... 

A 56-year-old Caucasian developed acute delirium having taken diphenhydramine 300 mg/day for 2 days to treat a pruritic rash. He subsequently developed visual and auditory hallucinations with erratic aggressive behavior. The author concluded that the drug-induced delirium was associated with the combination of treatment for an infected wound with linezolid with diphenhydramine given for secondary drug-induced rash (74). 

Recently, film dressings impregnated with an antibacterial (silver) for the management of infected wounds or a deodorizer (charcoal) for malodorous wounds have been introduced. 

Severe anaphylaxis has been reported in two patients with infected wounds that had been treated with topical rifamycin for several months (82). There was urticaria, angioedema, and hypotension in one case, and urticaria, wheezing, dyspnea, and hypotensive shock in the other. In both cases, prick tests with 10% rifamycin solution were positive, while there were no positive reactions in 20 controls.
