REVIEW
Lorenzo Fagotti, Jakub Tatka, Mauro Jose Costa Salles, Marcelo C Queiroz
PURPOSE OF REVIEW: Although a two-stage exchange revision is reported to have a high success rate, this strategy may fail as a treatment for prosthetic joint infection (PJI). When it does, resection arthroplasty, arthrodesis, amputation, and chronic antibiotic suppression may play a role. The purpose of this review is to determine which are the main risk factors for a two-stage exchange failure and to analyze the indications and results of resection arthroplasty, arthrodesis, amputation, and antibiotic chronic suppression for PJI...

J D Sobel, R Sobel
Clinicians are increasingly challenged by patients with refractory vulvovaginal candidiasis (VVC) caused by azole-resistant Candida species. Fluconazole resistant C.albicans is a growing and perplexing problem following years of indiscriminate drug prescription and unnecessary drug exposure and for which there are few therapeutic alternatives. Regrettably, although the azole class of drugs has expanded, new classes of antifungal drugs have not been forthcoming, limiting effective treatment options in patients with azole resistant Candida vaginitis...

Amphotericin B (AmB), a potent antifungal drug, presents physicochemical characteristics that impair the development of suitable dosage forms. In order to overcome the AmB insolubility, several lipid carriers such as microemulsions have been developed. In this context, the bullfrog oil stands out as an eligible oily phase component, since its cholesterol composition may favor the AmB incorporation. Thus, the aim of this study was to develop a microemulsion based on bullfrog oil containing AmB. Moreover, its thermal stability, antifungal activity, and cytotoxicity in vitro were evaluated...

Yasuhiro Hori, Kazutoshi Shibuya
Echinocandins are antifungal agents that specifically inhibit the biosynthesis of 1,3-β-D-glucan, a major structural component of fungal cell walls. Echinocandins are recommended as first-line or alternative/salvage therapy for candidiasis and aspergillosis in antifungal guidelines of various countries. Resistance to echinocandins has been reported in recent years. The mechanism of echinocandin resistance involves amino acid substitutions in hot spot regions of the FKS gene product, the catalytic subunit of 1,3-β-D-glucan synthase...

Vulvovaginal candidiasis (VVC) is the second most common cause of vaginitis after bacterial vaginosis, affecting millions of women worldwide every year. Candida albicans is the most frequent agent of VVC followed by other species of Candida such as C. glabrata and C. parapsilosis. Out of a total of 100 clinical isolates of Candida spp. obtained from patients diagnosed with VVC, 84 were identified as C. albicans, while the remaining isolates were identified as non--albicans Candida strains. Phospholipases and proteinases were produced by a majority of the C...

Difficulties in the treatment of Candida spp. invasive infections are usually related to the formation of biofilms. The aim of this study was to determine the effects of molecular weight (MW) of chitosan (using high (HMW), medium (MMW) and low (LMW) molecular weight chitosan) on Candida albicans, Candida tropicalis and Candida parapsilosis sensu stricto. The deacetylation degree (DD) and molecular weight M were measured by potentiometric titration and viscosimetry, respectively. The planktonic shape activity was quantified by broth microdilution, and the activity against biofilm was quantified by metabolic activity through XTT 2,3-bis(2-methoxy-4-nitro-5-sulfophenyl)-5-[(phenylamino)carbonyl]- 2H-tetrazolium hydroxide and biomass formation (crystal violet)...

Thomas Neß
Endophthalmitis is a severe intraocular infection with potentially devastating consequences, such as becoming blind or loss of an eyeball. It can be exogenous (postoperative or posttraumatic) or endogenous. The most frequent causes of postoperative endophthalmitis are cataract surgery and intravitreal injections. Typical symptoms are pain and loss of visual acuity. Hypopyon and infiltration of the vitreous body with the loss of the red reflex are the most important clinical findings for endophthalmitis. The diagnosis is primarily clinical and supported by microbiological cultures and PCR from the vitreous body and/or anterior chamber and is of use for a targeted treatment...
