The present study reports an effective strategy, which opens new avenues for the treatment of this public health problem. The MAC<sup>®</sup> Methodology, conventional laser light-emitting (LLLT)/LED) methods are based on the biphasic response demonstrated many times in LLLT research and as with other forms of drugs, a “drug” (irradiation parameters) and a “dose” (irradiation times) and the “Arndt-Schulz Law” is often cited as a suitable model to describe the dose-dependent effects of LLLT. This method uses photopharmaceuticals, cell markers and the use of correct parameters for each case to induce the acceleration of tissue repair. The present study shows a case of a 32-year-old patient diagnosed with recurrent candidiasis 4 years ago. Eighteen sessions were performed (every other day) using a photoactivated component (Methylene blue 1% + Clotrimazole 1%) and LED phototherapy (red, blue and violet) with emission times of 60 - 260 seconds for each applicator, according to the dose recommendations of the scar acceleration method (MAC<sup>®</sup>). At the sixth treatment session there was a noticeable decrease in the itching sensation reported by the patient. In session 11 she reported feeling a great improvement, indicating that she no longer felt itching in any area after 18 sessions. The present case demonstrates new methodologies to treat common problems in the population that have a positive impact on the quality of life. This methodology has a promising future because it is non-invasive and requires a great biological transformation for inflammatory, fungal and viral control.展开更多

Methods: This observational study included clinical vaginal secretion samples collected over four years from 88 women, ranging in age from 18 to 65 years, from medical centers of Sao Paulo and Mogi das Cruzes, Brazil. Thirty-six of these women were asymptomatic (control group) and 52 presented clinical condition compatible with vulvovaginitis (38 primary or episodic as non-recurrent forms, and 14 recurrent vulvovaginal candidiasis). A portion of each sample was plated on Sabouraud dextrose agar with chloramphenicol and grown on CHROMagar Candida for presumptive characterization. The identification of the species was obtained by sequencing of the ITS1 region of rDNA. α-DF genes were amplified for subsequent evaluation of polymorphisms by endonuclease restriction assay. Results: From 88 samples were isolated 60 Candida albicans and 28 non-albicans Candida spp. Resistant C. albicans strains and non-albicans Candida spp. were more prevalent in recurrence. In all groups, the number of resistant non-albicans Candida spp. was most high than susceptible strains. α-DF1, α-DF3 and α-DF1/α-DF3 genotypes were found in 32 (36.4%), 17 (19.3%), 6 (6.8%) vaginal samples, respectively. About 33 samples were not amplified. Recurrence and severe disease were more observed in homozygous population. Conclusions: Non-albicans Candida spp. and homozygotic α-DF genotipes (α-DF1 and α-DF3) were more related with severe clinical signs and recurrence. Further studies about vulvovaginal candidiasis and α-DF genes are necessary to access the more comprehensive role of defensins in clinical manifestations.展开更多

Combination therapy with topical antifungals may improve therapy outcome, but still standard agents as fluconazole or itraconazole often fail. Posaconazole is a new systemic triazole with a wide antifungal spectrum including rare Candida species. Up to now, no clinical trials with posa- conazole in chronic recurrent VVC have been undertaken. Here, first results of the application of a new therapy regimen consisting of oral posaconazole in combination with topical ciclopiroxolamine are presented. 15 patients with chronic recurrent VVC caused by C. glabrata have been treated. 14 of these patients experienced successful therapy, clinical and mycological cure 30 days after begin of therapy has been observed. Long-term results are promising, as in 4 patients clinical and mycologic cure persists for more than 1 year up to now.展开更多

Historically, 90% of cultured yeast species were C. albicans. However, due to a variety of interventions, the proportion of non-albicans Candida (NAC) infections appears to be increasing. We sought to estimate the current prevalence of Candida vulvovaginitis and the species-specific distribution of such infections in recurrent cases. Methods: Women with recurrent vulvovaginal symptomatology referred to an Obstetrics and Gynecology practice were tested by genital fungus culture, Candida-specific polymerase chain reaction (PCR), or both between July 2010 and February 2013. Results: A total of 103 women were tested. Mean age was 45.6 years. Including only their most recent positive test result, 29.1% (30/103) of women tested positive for Candida by any of the above testing measures. Of those, 50% (15/30) tested positive for C. albicans and 50% (15/30) tested positive for a NAC species. Across all visits, 60% (18/30) tested positive for C. albicans, 56.7% (17/30) tested positive for NAC, and 16.7% (5/30) tested positive for both a C. albicans and a NAC species. Among all isolated NAC species, 28.6% (6/21) were determined to be C. glabrata, 23.8% (5/21) C. krusei, 23.8% (5/21) C. parapsilosis, and 23.8% (5/21) other Candida species. Conclusion: Approximately 30% of women with recurrent vulvovaginal symptomatology have detectable Candida strains and it appears that NAC species may cause half of all these infections. This is imperative because NAC infections are usually more difficult to diagnose and are resistant to most treatments.展开更多

Vulvovaginal candidiasis (VVC) is frequently related to vaginal carriage of Candida albicans, an opportunistic polymorphic fungus, which colonizes the human skin, the mucosa and the reproductive tract. Actually, standard treatments to counteract vaginitis include several topical and oral treatments. The aim of this study was to evaluate the efficacy of a new biguanide compound, polyhexamethylene biguanide (PHMB) in avaginal solution, in women affected by vaginal candidiasis. For this reason, 40 women showing the symptoms previously ascribed to vaginal candidiasis were recruited and treated with a single PHMB dose of vaginal solution. After a single dose of treatment, 80% of them had a complete resolution of the fungal infection;furthermore, all of them reported clinical benefits, statistically significant reduction in both clinical signs and symptoms of candidiasis and a score’s reduction of 50%.展开更多

The purpose of this study was to describe women’s life experiences in managing the symptoms of bacterial vaginosis and Candida. Sixteen women were recruited and participated in an interview study when they contacted a Swedish gynecology clinic with vaginal complaints that ranged from and included abnormal discharge, irritation itching along with serious malodor. An interpretive phenomenological approach was used with an individual interview to get a more intimate understanding of the women experiencing these problems. The finding of this study shows that managing the recurrent symptoms of the infections remains to be a challenge for women as it has a clearly negative impact on the quality of their lives. Four themes developed: frustration and mood disorders, intimacy changes in the relationship, exposure, hope and relief. The women had high hopes of eliminating the symptoms within the six-month study period. The treatment program, with its well-developed guidelines and continuity of care within the context of the study greatly improved the quality of life of these women. Women had feelings of frustration and anxiety when nothing could cure their problem while they had also a great hope to get rid of the symptoms with a long striking treatment. Well-developed guidelines and continuity of care can help these women to have an improved quality of life.展开更多

The purpose of this study was to describe the species distribution and in vitro antifungal susceptibility of Candida species (Candida spp.) isolated from patients with VVC over 8 years. Methods: Species which isolated from patients with VVC in Peking University First Hospital were identified using chromogenic culture media. Susceptibility to common antifungal agents was determined using agar diffusion method based on CLSI M44-A2 document. SPSS software (version 14.0, Inc., Chicago, IL, USA) was used for statistical analysis, involving statistical description and Chi-square test. Results: The most common strains were Candida (C.) albicans, 80.5% (n = 1775) followed by C. glabrata, 18.1% (n = 400). Nystatin exhibited excellent activity against all species (〈4% resistant JR]). Resistance to azole drugs varied among different species. C. albicans: clotrimazole (3.1% R) 〈 fluconazole ( 16.6% R) 〈 itraconazole (51.5% R) 〈 mieonazole (54.0% R), C. glabrata: miconazole (25.6% R) 〈 clotrimazole (50.5% R) 〈 itraconazole (61.9% R) 〈 fluconazole (73.3% R); Candida krusei: clotrimazole (0 R) 〈 fluconazole (57.7% R) 〈 miconazole (73.1% R) 〈 itraconazole (83.3% R). The susceptibility of fluconazole was noticeably decreasing among all species in the study period. Conclusions: Nystatin was the optimal choice for the treatment of VVC at present. The species distribution and in ~'itro antifungal susceptibility of Candida spp. isolated from patients with VVC had changed over time.展开更多

Methods Totally 237 reproductive-aged women with RVVC in an acute episode were studied. Whereas 230 healthy reproductive-aged women were enrolled as the control. The vaginal pH was evaluated, while vaginal secretions were sampled for Gram's staining and oilmicroscopy. By Nugent score system, the composition of vaginal communities was determined, and other micro-ecological features were approached. To describe other features of vaginal microbiota, the community's bacteria density, species diversity and predominant species were evaluated at 1 000 X magnification. Results The vaginal pH (4.53 ~ 0.30) and Nugent score (4.31 ___+ O. 73) in RVVC group were significantly increased compared with vaginal pH (4.11 __+ 0.30) and Nugent score (1.32 _+ 1.29) in control group (P〈O.05, respectively). The density of Lactoba- cillus in RVVC group was significantly lower than that in control group (P〈O.05), while the densities of Gardnerella vaginalis, Gram-positive cocci and other species were significantly higher respectively than those in control group (P〈O. 05). Species diversity of women with RVVC significantly exceeded that of control group (P〈O.05). More than half of vaginal communities in R VVC group lost Lactobacillus-dominating and were predominated by other bacteria such as Gardnerella vaginalis and Gram-positive cocci. The prevalence of Gardnerella vaginalis-dominating and Gram-positive cocci-domi- nating communities in RVVC group (37.55% and 19.83%) were significantly higher than those in control group (1.30% and 1.73%) (P〈0.05). Conclusion The significant changes in vaginal bacterial community were observed in RVVC women. Such variations in community might relate to vaginal biological barrier compromising and increase the risk to the recurrence of VVC. It is still controversial whether probiotics can prevent recurrences of VVC, and more randomized, doubleblind, placebo-controlled trials with a larger sample size should be carried out, so as to clarify its effects for the prophylaxis of RVVC.展开更多

Estrogen benzoate (E2) was given to mice at different concentrations ranging from 0.0 to 0.05 mg/mouse (4 levels) beginning 72 h prior to vaginal inoculation, then mice were in- oculated intravaginally with various concentrations of stationary-phase C. albicans blastoconidia (ATCC90028) (5 levels) in 20 μL of phosphate-buffered saline (PBS) in each E2 level. General state, scores of genital pathology, the hyphae and vaginal fungal burden (CFU) in vaginal lavage fluid, the hydrops rate of uterus and vaginal tissues for pathological section in mice were observed and ob- tained at day 2, 4, 7, 14 and 21 after inoculation. The results showed the infection rate in mice was related to the dosage of E2 and concentration of C. albicans blastoconidia. Additionally there was better cross-effect between the two treated factors. The infection rate was about 80% on the day 4, and could reach 100% on the day 7 until the end of experiment after inoculated intravaginally in groups of E2I3, E2 0.025 mg/mouse injected hypodermically and inoculated intravaginally with 5×104 C. albicans blastoconidia, and large amount of hyphae and blastoconidia could be observe in superfi- cial layer tissue and canal of vaginal by PAS. From the results in our experiment it was concluded that E2I3 was the optima construction condition in kunming mice.展开更多

Methods: 40 Candida isolates from episodes of vulvovaginal candidiasis were identified by classic methodologies. The susceptibility testing of the in vitro fluconazole and ketoconazole activity against the isolates was accessed by E-test. Results: C. albicans was the most common species identified in 70% of the occurrences followed by C. glabrata (20%), C. tropicalis (7.5%), and C. guilliermondii (2.5%). In the susceptibility profile to antifungal agents, 12.5% and 16.7% of the isolates obtained from primary and episodic vulvovaginal candidiasis were resistant to fluconazole, respectively. To ketoconazole, we found that 6.25% and 12.5% of the isolates respectively from primary vulvovaginal candidiasis (PVVC) and episodic vulvovaginal candidiasis (EVVC) had high MIC values. Conclusions: E-test is a reliable method for the susceptibility testing of Candida spp. due to its simplicity, reproducibility, and lack of specialized equipment. Resistant strains and non-albicans species were verified more in cases of EVVC than in PVVC. Clinical and mycological cure of patients with episodic vulvovaginal candidiasis or complicated cases occurred after prolonged treatment and sometimes with multiple antifungals use.展开更多

In th...The breast cancer care continuum entails detection, diagnosis, treatment, and survivorship. During this time, focus on the whole woman and medical concerns beyond the breast cancer diagnosis itself is essential. In this comprehensive review, we critically review and evaluate recent evidence regarding several topics pertinent to and specific for the woman living with a prior history of breast cancer. More specifically, we discuss the most recent recommendations for contraceptive options including long-acting reversible contraception and emergency contraception, fertility and pregnancy considerations during and after breast cancer treatment, management of menopausal vasomotors symptomsand vulvovaginal atrophy which often occurs even in young women during treatment for breast cancer. The need to directly query the patient about these concerns is emphasized. Our focus is on non-systemic hormones and non-hormonal options. Our holistic approach to the care of the breast cancer survivor includes such preventive health issues as sexual and bone health,which are important in optimizing quality of life. We also discuss strategies for breast cancer recurrence surveillance in the setting of a prior breast cancer diagnosis. This review is intended for primary care practitioners as well as specialists caring for female breast cancer survivors and includes key points for evidence-based best practice recommendations.展开更多

It was found that Sap2 and Sap5 were the most common genes expressed during infection; Sap3 and Sap4 were detected in all subjects and all 6 SAP genes were simultaneously expressed in some patients with vaginal candidiasis. It was suggested that the SAP family is expressed by Candida albicans during infection in human and that Candida albi- cans infection is associated with the differential expression of individual SAP genes which may be involved in the pathogenesis of vaginal candidiasis.展开更多

文摘Objective: To evaluate the alpha-defensin (α-DF) genes polymorphism in women with vulvovaginal candidiasis and recurrence. Methods: This observational study included clinical vaginal secretion samples collected over four years from 88 women, ranging in age from 18 to 65 years, from medical centers of Sao Paulo and Mogi das Cruzes, Brazil. Thirty-six of these women were asymptomatic (control group) and 52 presented clinical condition compatible with vulvovaginitis (38 primary or episodic as non-recurrent forms, and 14 recurrent vulvovaginal candidiasis). A portion of each sample was plated on Sabouraud dextrose agar with chloramphenicol and grown on CHROMagar Candida for presumptive characterization. The identification of the species was obtained by sequencing of the ITS1 region of rDNA. α-DF genes were amplified for subsequent evaluation of polymorphisms by endonuclease restriction assay. Results: From 88 samples were isolated 60 Candida albicans and 28 non-albicans Candida spp. Resistant C. albicans strains and non-albicans Candida spp. were more prevalent in recurrence. In all groups, the number of resistant non-albicans Candida spp. was most high than susceptible strains. α-DF1, α-DF3 and α-DF1/α-DF3 genotypes were found in 32 (36.4%), 17 (19.3%), 6 (6.8%) vaginal samples, respectively. About 33 samples were not amplified. Recurrence and severe disease were more observed in homozygous population. Conclusions: Non-albicans Candida spp. and homozygotic α-DF genotipes (α-DF1 and α-DF3) were more related with severe clinical signs and recurrence. Further studies about vulvovaginal candidiasis and α-DF genes are necessary to access the more comprehensive role of defensins in clinical manifestations.

Long-term results are promising, as in 4 patients clinical and mycologic cure persists for more than 1 year up to now.
文摘Background: Candida vulvovaginitis is one of the most frequently diagnosed conditions in women’s care practices. Historically, 90% of cultured yeast species were C. albicans. However, due to a variety of interventions, the proportion of non-albicans Candida (NAC) infections appears to be increasing. We sought to estimate the current prevalence of Candida vulvovaginitis and the species-specific distribution of such infections in recurrent cases.

Of those, 50% (15/30) tested positive for C. albicans and 50% (15/30) tested positive for a NAC species. Across all visits, 60% (18/30) tested positive for C. albicans, 56.7% (17/30) tested positive for NAC, and 16.7% (5/30) tested positive for both a C. albicans and a NAC species. Among all isolated NAC species, 28.6% (6/21) were determined to be C. glabrata, 23.8% (5/21) C. krusei, 23.8% (5/21) C. parapsilosis, and 23.8% (5/21) other Candida species. Conclusion: Approximately 30% of women with recurrent vulvovaginal symptomatology have detectable Candida strains and it appears that NAC species may cause half of all these infections. This is imperative because NAC infections are usually more difficult to diagnose and are resistant to most treatments.

文摘Background: Vulvovaginal candidiasis (WC) was a common infection associated with lifelong harassment of woman's social and sexual life. The purpose of this study was to describe the species distribution and in vitro antifungal susceptibility of Candida species (Candida spp.) isolated from patients with VVC over 8 years. Methods: Species which isolated from patients with VVC in Peking University First Hospital were identified using chromogenic culture media. Susceptibility to common antifungal agents was determined using agar diffusion method based on CLSI M44-A2 document. SPSS software (version 14.0, Inc., Chicago, IL, USA) was used for statistical analysis, involving statistical description and Chi-square test. Results: The most common strains were Candida (C.) albicans, 80.5% (n = 1775) followed by C. glabrata, 18.1% (n = 400). Nystatin exhibited excellent activity against all species (〈4% resistant JR]). Resistance to azole drugs varied among different species. C. albicans: clotrimazole (3.1% R) 〈 fluconazole ( 16.6% R) 〈 itraconazole (51.5% R) 〈 mieonazole (54.0% R), C. glabrata: miconazole (25.6% R) 〈 clotrimazole (50.5% R) 〈 itraconazole (61.9% R) 〈 fluconazole (73.3% R); Candida krusei: clotrimazole (0 R) 〈 fluconazole (57.7% R) 〈 miconazole (73.1% R) 〈 itraconazole (83.3% R). The susceptibility of fluconazole was noticeably decreasing among all species in the study period. Conclusions: Nystatin was the optimal choice for the treatment of VVC at present. The species distribution and in ~'itro antifungal susceptibility of Candida spp. isolated from patients with VVC had changed over time.
文摘OBJECTIVE:To summarize and evaluate the effectiveness and safety of Redcore lotion on treating vulvovaginal candidiasis(VVC)using a systematic review and Meta-analysis of randomized controlled trials.METHODS:A systematic literature search was performed in five English and three Chinese electronic databases up to October 2019.Randomized controlled trials in the treatment for VVC were included;only studies which compared the effectiveness and safety of Redcore lotion plus miconazole with miconazole alone were included.Relative risk(RR)and 95%confidence intervals(CI)were used in the Meta-analysis.RESULTS:Seven studies involving 768 patients suffering from VVC were identified;468 of the patients were pregnant women(60.9%).Combination group(Redcore lotion plus miconazole)was more effective in redu CIng symptomatic episodes of VVC than miconazole alone,with respect to cure rate(RR,1.31;95%CI,1.09-1.57;P=0.01),fungal culture negative rate(RR,1.21;95%CI,1.04-1.41;P=0.01),and effective rate(RR,1.18;95%CI,1.05-1.35;P=0.01).Subgroup analyses for pregnant women also showed that the combination group had superior outcomes with respect to VVC cure rate(RR,1.48;95%CI,1.16-1.88,P<0.01),fungal culture negative rate(RR,1.26;95%CI;1.09-1.47;P<0.01),and effective rate(RR,1.25;95%CI,1.10-1.42;P<0.01).Additionally,the observed risk of adverse events was lower in the combination medication group(RR,0.30;95%CI,0.14-0.65;P<0.01).CONCLUSIONS:Though overall quality of individual studies was low,Redcore lotion plus miconazole can significantly improve clinical effectiveness and safety compared with miconazole alone.
文摘Objective To investigate the features of vaginal bacteria community in women with recurrent vulvovaginal candidiasis (R VVC) and its etiological risk in vaginal health. Methods Totally 237 reproductive-aged women with RVVC in an acute episode were studied. Whereas 230 healthy reproductive-aged women were enrolled as the control. The vaginal pH was evaluated, while vaginal secretions were sampled for Gram's staining and oilmicroscopy. By Nugent score system, the composition of vaginal communities was determined, and other micro-ecological features were approached. To describe other features of vaginal microbiota, the community's bacteria density, species diversity and predominant species were evaluated at 1 000 X magnification. Results The vaginal pH (4.53 ~ 0.30) and Nugent score (4.31 ___+ O. 73) in RVVC group were significantly increased compared with vaginal pH (4.11 __+ 0.30) and Nugent score (1.32 _+ 1.29) in control group (P〈O.05, respectively). The density of Lactoba- cillus in RVVC group was significantly lower than that in control group (P〈O.05), while the densities of Gardnerella vaginalis, Gram-positive cocci and other species were significantly higher respectively than those in control group (P〈O. 05). Species diversity of women with RVVC significantly exceeded that of control group (P〈O.05). More than half of vaginal communities in R VVC group lost Lactobacillus-dominating and were predominated by other bacteria such as Gardnerella vaginalis and Gram-positive cocci. The prevalence of Gardnerella vaginalis-dominating and Gram-positive cocci-domi- nating communities in RVVC group (37.55% and 19.83%) were significantly higher than those in control group (1.30% and 1.73%) (P〈0.05). Conclusion The significant changes in vaginal bacterial community were observed in RVVC women. Such variations in community might relate to vaginal biological barrier compromising and increase the risk to the recurrence of VVC. It is still controversial whether probiotics can prevent recurrences of VVC, and more randomized, doubleblind, placebo-controlled trials with a larger sample size should be carried out, so as to clarify its effects for the prophylaxis of RVVC.

文摘Inflammation of the vagina and vulva caused by Candida is called vulvovaginal candidiasis(VVC).Risk factors for VVC include pregnancy,diabetes mellitus,frequent oral sexual intercourse,and the use of tight synthetic underwear and systemic antibiotics.Candida albicans,which belongs to the normal flora of the vagina,is the most common cause of VVC.However,an increase in VVC episodes caused by non-albicans Candida species,including Candida glabrata,Candida tropicalis,Candida krusei and Candida parapsilosis,has been reported.In this study,a total of 100 Candida isolates obtained from patients with vaginitis symptoms were evaluated.The susceptibility of the Candida strains to amphotericin B,itraconazole,fluconazole,ketoconazole,voriconazole and caspofungin was investigated using the reference broth microdilution method.Risk factors and demographic characteristics of the patients and the identified Candida species were also investigated.Among the 100 Candida strains isolated from vaginal samples,47(47%)were C.albicans,43(43%)C.glabrata,5(5%)C.kefyr,2(2%)C.krusei,2(2%)C.tropicalis and 1(1%)was Candida guilliermondii.The incidences of Candida susceptibility to caspofungin,fluconazole,itraconazole,voriconazole,ketoconazole and amphotericin B were 75%,35%,27%,80%,97%and 100%,respectively.Also,there was a significant difference in antifungal susceptibility among patients belonging to certain risk groups,such as patients previously using antibiotics and recurrent cases.Prevalence of non-albicans Candida species and antifungal resistance,especially against azoles,are both increasing,and certain risk factors should be monitored strictly.

文摘The model of vaginal candidiasis in Kunming mice was constructed in order to search for the optima construction conditions and provide an economic animal model of Candida albicans (C. albicans) vaginitis. Estrogen benzoate (E2) was given to mice at different concentrations ranging from 0.0 to 0.05 mg/mouse (4 levels) beginning 72 h prior to vaginal inoculation, then mice were in- oculated intravaginally with various concentrations of stationary-phase C. albicans blastoconidia (ATCC90028) (5 levels) in 20 μL of phosphate-buffered saline (PBS) in each E2 level. General state, scores of genital pathology, the hyphae and vaginal fungal burden (CFU) in vaginal lavage fluid, the hydrops rate of uterus and vaginal tissues for pathological section in mice were observed and ob- tained at day 2, 4, 7, 14 and 21 after inoculation. The results showed the infection rate in mice was related to the dosage of E2 and concentration of C. albicans blastoconidia. Additionally there was better cross-effect between the two treated factors. The infection rate was about 80% on the day 4, and could reach 100% on the day 7 until the end of experiment after inoculated intravaginally in groups of E2I3, E2 0.025 mg/mouse injected hypodermically and inoculated intravaginally with 5×104 C. albicans blastoconidia, and large amount of hyphae and blastoconidia could be observe in superfi- cial layer tissue and canal of vaginal by PAS. From the results in our experiment it was concluded that E2I3 was the optima construction condition in kunming mice.
文摘Purpose: To evaluate the profile of in vitro susceptibility of yeasts isolated from cases of primary and espisodic vulvovaginitis to two antifungal agents. Methods: 40 Candida isolates from episodes of vulvovaginal candidiasis were identified by classic methodologies. The susceptibility testing of the in vitro fluconazole and ketoconazole activity against the isolates was accessed by E-test. Results: C. albicans was the most common species identified in 70% of the occurrences followed by C. glabrata (20%), C. tropicalis (7.5%), and C. guilliermondii (2.5%). In the susceptibility profile to antifungal agents, 12.5% and 16.7% of the isolates obtained from primary and episodic vulvovaginal candidiasis were resistant to fluconazole, respectively. To ketoconazole, we found that 6.25% and 12.5% of the isolates respectively from primary vulvovaginal candidiasis (PVVC) and episodic vulvovaginal candidiasis (EVVC) had high MIC values. Conclusions: E-test is a reliable method for the susceptibility testing of Candida spp. due to its simplicity, reproducibility, and lack of specialized equipment. Resistant strains and non-albicans species were verified more in cases of EVVC than in PVVC. Clinical and mycological cure of patients with episodic vulvovaginal candidiasis or complicated cases occurred after prolonged treatment and sometimes with multiple antifungals use.

文摘The breast cancer care continuum entails detection, diagnosis, treatment, and survivorship. During this time, focus on the whole woman and medical concerns beyond the breast cancer diagnosis itself is essential. In this comprehensive review, we critically review and evaluate recent evidence regarding several topics pertinent to and specific for the woman living with a prior history of breast cancer. More specifically, we discuss the most recent recommendations for contraceptive options including long-acting reversible contraception and emergency contraception, fertility and pregnancy considerations during and after breast cancer treatment, management of menopausal vasomotors symptomsand vulvovaginal atrophy which often occurs even in young women during treatment for breast cancer. The need to directly query the patient about these concerns is emphasized. Our focus is on non-systemic hormones and non-hormonal options. Our holistic approach to the care of the breast cancer survivor includes such preventive health issues as sexual and bone health,which are important in optimizing quality of life. We also discuss strategies for breast cancer recurrence surveillance in the setting of a prior breast cancer diagnosis. This review is intended for primary care practitioners as well as specialists caring for female breast cancer survivors and includes key points for evidence-based best practice recommendations.
文摘In order to analyze the in vivo expression of Candida albicans secreted aspartyl pro- teinases (SAP) in human vaginal infection, the vaginal secretion from 29 human subjects was col- lected by vaginal swab, and the expression of SAP1–SAP6 was detected by reverse-transcriptase po- lymerase chain reaction using specific primer sets. It was found that Sap2 and Sap5 were the most common genes expressed during infection; Sap3 and Sap4 were detected in all subjects and all 6 SAP genes were simultaneously expressed in some patients with vaginal candidiasis. It was suggested that the SAP family is expressed by Candida albicans during infection in human and that Candida albi- cans infection is associated with the differential expression of individual SAP genes which may be involved in the pathogenesis of vaginal candidiasis.
