Eficacia del econazol en embarazadas con candidiasis vulvo-vaginal

Among the female patients attending the out patient clinic of the Obstetric Service of the University Hospital of Caracas, Venezuela a hundred were chosen who presented vaginal discharge and itching. The presence of C. albicans and the existence of candidiasis in the vulvo-vagina of the 100 pregnant women was investigated. Those patients where candidiasis was found, were also investigated as to the simultaneous presence of C. albicans in the mouth and the anal skin. Gyno-Pevaryl therapy was performed by administering one 150 mg ovule daily for three consecutive days. At the same time, their partners were treated with Pevaryl 1% cream. The post-therapy control was made 36 hours after conclusion of treatment and further check-up were made one week and two weeks later. Only those patients who attended the post-treatment controls were taken into account for the evaluation of the results. C. albicans was identified in 60 cases by nascent culture of the vulvar secretions, using a bile-agar medium. Of these, 50 had vulvo-vaginal candidiasis (hyphae and blastospores on direct examination). 92% of the women with vulvo-vaginal candidiasis complained about pruritus at the moment of the examination. No significant differences were observed with respect to the age, the period of gestation and parity of the positive and negative patients. Of the 40 patients who attended only the first control, 23 were cured (57.5%), 9 improved (22.5%) and 8 (20%) were not cured. The cure rate increased to 70% and 72.5% taking into account those patients, who also attended the second and the third consecutive treatment sessions, respectively. In those patients suffering from vulvo-vaginal candidiasis, 37.5% were found to be carriers of C. albicans in the mouth and 70% also in the anal region. This seems to indicate that the mouth and the anal region can constitute the source of re-infection in the majority of the cases following topical vaginal treatment.     

The effect of vaginal candidiasis on the levels of the oxidative biomarkers in plasma and tissue samples of diabetic rats

The aim of this study is to determine the relation between diabetes and vaginal candidiasis in terms of oxidative biomarker levels in a vaginal candidiasis model of the diabetic rats by evaluating malondialdehyde (MDA), sulphydrile groups or glutathione (RSH), and ascorbic acid (C vit) levels. All rats were randomly divided into five groups. All of the groups were observed for 21 days. In the treated diabetes groups, MDA (0.90, 0.68 nmol/ml and 3.78, 3.79 nmol/g tissue, plasma and vaginal tissue, respectively) and RSH (227, 171 nmol/100 ml 0.38, 0.37 μmol/g tissue, plasma and vaginal tissue, respectively) levels were found to be decreased while the levels of C vit were found to be increased (0.49, 0.37 μmol/l 2.39, 2.01 nmol/g tissue plasma, and vaginal tissue, respectively) (P < 0.05). In the groups of untreated diabetes, vaginal candidiasis were found to be more serious and oxidative biomarkers were found to be increased (MDA 1.30, 1.26 nmol/ml and 7.82, 2.37 nmol/g tissue and RSH 258, 145 nmol/100 ml and 0.31, 0.46 μmol/g tissue) while the antioxidant C vit levels were found to be decreased (0.24, 0.17 μmol/l 1.33, 2.66 nmol/g tissue) (P < 0.05). RSH, plasma MDA, blood glucose, and tissue MDA levels of vaginal candidiasis embedeled diabetic rats, were found to be higher than those in untreated diabetic and untreated vaginitis enbedeled rats ‹P < 0.05’. Vaginal candidiasis caused oxidative stress in diabetic rats working together. Systemic oxidative stress biomarkers were found to be affected from vaginal candidiasis although it was a local mucosal infection. This study was presented as a poster in the conference of ‹2nd Trends in Medical Mycology, 23–26 October 2005, Berlin, Germany’.

Antifungal drug resistance pattern of Candida. spp isolated from vaginitis in Ilam-Iran during 2013-2014

Vaginal Candidiasis is the most common and important opportunistic fungal infection in women. By increasing use of antifungal drugs in recent years, it has caused drug resistance. This study aims to evaluate antifungal drugs susceptibility of Candida. spp isolated of women with vaginitis from Ilam-Iran during 2013-2014. samples were collected and cultured from 385 women with vaginitis, then Candida.spp was diagnosed by standard method. Antifungal drug susceptibility test for nystatin 100 unit/disk, fluconazole 10µg/disk, itraconazole 10µg/disk, ketoconazole 10µg/disk, amphotericinB 20µg/disk, clotrimazole 10µg/disk, posaconazole 5µg/disk, and voriconazole 1µg/disk were carried out by M44-A method(CLSI). From all culture positive samples, 150 isolates were Candida albicans and 89 isolates were non-albicans. The resistance to fluconazole, itraconazole, ketoconazole, clotrimazole, voriconazole, posaconazole, nystatin and amphotericin B was 76%, 62%, 72%, 55%, 6%, 7%, 1% and 0%. The highest resistance was seen for fluconazole , itraconazole, and the highest susceptible was seen for nystatin and amphotericin B. These results indicate nystatin and amphotericin B can be used as the first line for empirical therapy of vaginal candidiasis in the district.     

Zinc and Propolis Reduces Cytotoxicity and Proliferation in Skin Fibroblast Cell Culture: Total Polyphenol Content and Antioxidant Capacity of Propolis

It has been demonstrated that zinc exerts its beneficial influence on skin fibroblasts. Propolis, a complex mixture of plant-derived and bees’ products, was reported to stimulate cicatrization processes in skin and prevent infections. The aim of this study was to find out how zinc and propolis influence human skin fibroblasts in cell culture and to compare the effect of individual compounds to the effect of a mixture of zinc and propolis. In this study, zinc, as zinc aspartate, at a concentration of 16 μM, increased human fibroblasts proliferation in cell culture, whereas propolis at a concentration of 0.01 % (w/v) revealed antiproliferative and cytotoxic action followed by mild cell necrosis. In culture, zinc was effectively transported into fibroblasts, and propolis inhibited the amount of zinc incorporated into the cells. An addition of propolis to the medium caused a decrease in the Zn(II) amount incorporated into fibroblasts. The obtained results also indicate an appreciable antioxidant property of propolis and revealed its potential as a supplement when applied at doses lower than 0.01 % (w/v). In conclusion, the present study showed that zinc had a protective effect on human cultured fibroblasts’ viability, although propolis revealed its antiproliferative action and caused mild necrosis.     

Raman spectroscopic study of spatial distribution of propolis in comb of Apis mellifera carnica (Pollm.)

Micro-Raman spectroscopy and Raman mapping are applied to investigate the spatial distribution and chemical composition of wax and propolis in the comb of Apis mellifera carnica (Pollm). A thick layer of propolis at the rim of some cells is identified by Raman spectroscopy. Raman mapping is applied to resolve the distribution of propolis and wax on a micron scale. Both components are connected at the rim of the cell with a mixture of wax and propolis. A layer of almost pure propolis is found on top of the mixture. It appears that even in the mixture, where both components come into close contact, the propolis and the wax remain separated and keep their chemical identity.     

Co-administration of immunomodulator tuftsin and liposomised nystatin can combat less susceptible Candida albicans infection in temporarily neutropenic mice

In order to develop a prospective chemotherapeutic agent against opportunistic infections, it is important to know that host factors such as degree of immunological debility as well as recovery of immune functions to normality may contribute significantly to a successful elimination of the pathogens. We demonstrated previously that concomitant delivery of antimicrobial agents and immunomodulators to the pathogen harbouring-host contributes to the complete elimination of the deep-seated fungal infections (aspergillosis and candidiasis) in animals with normal immune status. Considering that neutropenic hosts are the main targets of such infections, it can be argued about the potential of the immunomodulator-based therapy in subjects with non-functional immune system. To resolve the hypothesis, we studied the role of immunomodulator tuftsin against experimental murine candidiasis in temporarily neutropenic Balb/c mice. The neutropenic mice were challenged with an isolate of Candida albicans that was showing less susceptibility to both free and liposomised-amphotericin B. The co-administration of tuftsin increased the efficiency of liposomised-polyene antibiotics (nystatin and amphotericin B) against experimental murine candidiasis in immunocompromised Balb/c mice. Pretreatment with liposomised tuftsin prior to C. albicans infection clearly enhanced protection against candidiasis, suggesting a prophylactic role of tuftsin in normal and temporarily neutropenic animals.     

Propolis as a novel antibacterial agent

Propolis (bee glue) is a bee glue, sticky resinous material released from various plant sources such as bud exudates, flowers, and leaves modified by bee secretions and wax propolis is composed of resins, waxes, polyphenols, polysaccharides, volatile materials, and secondary metabolites that are responsible for various bioactivity such as antibacterial, anti-angiogenic, antiulcer, anti-inflammatory, antioxidant, and anti-viral activities. The physico-chemical characteristics and the natural properties of various kinds of propolis have been studied for the past decade. Novel active anti-microbial compounds have been identified in propolis. Those compounds positively modulated the antimicrobial resistance of multidrug resistant bacteria. Published research has indicated that propolis and its derivatives has many natural antimicrobial compounds with a broad spectrum against different types of bacteria and that it enhanced the efficacy of conventional antibiotics. Besides, the combination of propolis with other compounds such as honey has been studied whereby, such combinations have a synergistic effect against bacterial strains such as Escherichia coli and Staphylococcus aureus. The activity of propolis is very much dependent on seasonal and regional factors, and Middle Eastern propolis have shown best antibacterial efficacy. Propolis and its main flavonoids ingredients should not be overlooked and should be evaluated in clinical trials to better elucidate their potential application in various fields of medicine. Clinical antibacterial potential and its use in new drugs of biotechnological products should be conducted. This review aims at highlighting some of the recent scientific findings associated with the antibacterial properties of propolis and its components.     

Vulvovaginal candidiasis in girls (guidelines for a practitioner)]

There are many publications on the problems of the vaginal candidiasis treatment. Still, the actuality is in the frequency of the relapses and registration of the pediatric cases. Unfortunately, the majority of the pediatrists prescribe antibiotics but either forget to prescribe the simultaneous use of antifungal drugs, or prescribe nystatin, an antimycotic, that is known to be active only in the intestine lumen. As a result, candidiasis of the stomatopharynx or vagina is developed. Of no less importance is the fact of marketing many generics in Russia, which often prove to be false after their detailed investigation. The paper presents specific characteristics pertaining to the origin and development of vulvovaginal candidiasis in girls and indicates drugs with proved efficacy in normalization of the vagina microbiocenosis in girls.

Anti-fungal resistance in candida isolated from oral and diaper rash candidiasis in neonates

The purpose of the present study is to evaluate the sensitivity of Candida species isolated from oral candidiasis and diaper dermatitis infections in children. The children referring to private and public clinics in Ilam, Iran were exmined for oral candidiasis and diaper dermatitis. In this study, 248 oral candidiasis and diaper dermatitis samples were collected and cultured.Candida species were identified by using standard methods. Resistance and sensitivity to amphotericin B, nystatin, ketoconazole, fluconazole, itraconazole, clotrimazole, and posaconazole were determined using the CLSI M44-A standard disk diffusion method. From the 248 studied samples, 149 were positive for Candida, among which the Candida albicans was the most prevalent (64.4%). The resistance of different Candida species to nystatin, itraconazole, fluconazole, ketoconazole, clotrimazole, voriconazole, and posaconazole were 4, 43, 34.2, 34.9, 21.5, 6, and 6.7%, respectively. No resistance to amphotericin B was observed. Considering rather low resistance to nystatin, this drug is the best choice for oral candidiasis and diaper dermatitis.     

Strain-dependent migration of lymphocytes to the vaginal mucosa after peripheral immunization

We have previously demonstrated a genetic predisposition among mice regarding their ability to be protected against vaginal candidiasis after peripheral immunization. Both BALB/c and (BALB/cx C57BL/6) F1 mice are protected against vaginal candidiasis after subcutaneous immunization with Candida albicans extract and C57BL/6 mice are not protected by this immunization. In the present study, the ability of F1-derived immune cells to transfer protection to naive parental strains was observed in BALB/c recipient mice, but not apparent in B6 recipient mice. This result is highly suggestive that the microenvironment of the B6 mouse is responsible for the susceptible phenotype. Genetic studies using (BALB/cx C57BL/6)F1x C57BL/6 backcross mice demonstrated that two genes appeared to regulate the protective effect of peripheral immunization to vaginal challenge. Microsatellite mapping indicated that candidate loci involved in controlling the immune response to vaginal candidiasis after peripheral immunization included the intercellular adhesion molecule-1 (ICAM-1), the Icam-1 related sequence 1, and the Fc epsilon RII (P<0.01). Thus, the ability of cells to bind to vaginal endothelial cells may play an important role in protection against vaginal candidiasis mediated by peripheral immunization.     

Linking hyperelastic theoretical models and experimental data of vaginal tissue through histological data

Mechanical characterization of living tissues and computer-based simulations related to medical issues, has become increasingly important to improve diagnostic processes and treatments evaluation. This work proposes a link between the mechanical testing and the material model predictions through histological data of vaginal tissue. Histological data was used to link tensile testing experiments with material-dependent parameters; the approach was adequate to capture the nonlinear response of ovine vaginal tissue over a large strain range.The experimental data obtained on a previous study, has two main components: tensile testing and histological analysis of the ovine vaginal tissue. Uniaxial tensile test data and histological data were collected from three sheep groups: virgins, pregnant and parous. The distal part of vaginal wall was selected since it is prone to tears induced by vaginal delivery.The HGO (Holzapfel-Gasser-Ogden) model parameters were fitted using a stochastic approach, namely the Simple Genetic Algorithm (SGA). The SGA was able to fit the experimental data successfully (R² > 0.986). The dimensionless coefficient ξ, was highly correlated with histological data. The ratio was seen to increase linearly with increasing collagen content.Coefficient ξ brings a new way of interpreting and understanding experimental data; it connects the nonlinear mechanical behaviour (tensile test) with tissue’s morphology (histology). It can be used as an ‘inverse’ (approximate) method to estimate the mechanical properties without direct experimental measurements, through basic histology.In this context, the proposed methodology appears very promising in estimating the response of the tissue via histological information.     

Viability of plum ovules at different temperatures

The viability of ovules was studied in five plum cultivars under laboratory conditions at four constant temperatures: 5°C, 10°C, 15°C and 20°C and under field conditions over two years. During 10 days from the onset of full bloom, ovule viability in cvs ‘?a?anska Rana’, ‘?a?anska Najbolja’ and ‘?a?anska Lepotica’ was between 80–100 % at the temperatures of 5°C, 10°C and 15°C, in both years. In the same period, ovule viability in cvs ‘Wangenheims Frühzwetsche’ and ‘Po?ega?a’ was lower, but never below 50%. At the constant temperature of 20°C, all plum cultivars showed a decline in longevity of ovule viability, which was pronounced in cv. ‘?a?anska Rana’. During the 10 days from the onset of full bloom, ovule viability in all five plum cultivars under field conditions showed a high viability, which approximated to the ovule viability of the cultivars at the constant temperatures of 5°C, 10°C and 15°C, in both years. Determination of the longevity of ovule viability in the mentioned plum cultivars is of great importance due to its effect on the effective pollination period and fertilisation success. This paper deals in detail with the interrelations between the temperature effects on ovule viability, pollen tube growth and fertilisation, as well as on fruit setting.     

阴道菌群结构分析在 宫腔粘连患者中的临床意义

目的对宫腔粘连患者菌群结构进行评价,探讨阴道微生态在宫腔粘连中的临床意义。方法选取2014年8月至2016年8月在我院计划生育病区诊断为宫腔粘连的患者100例为试验组,同期门诊100例健康体检者为对照组。对其阴道分泌物进行湿片镜检及微生态学检测,比较两组研究对象的阴道微生态情况。结果宫腔粘连组与对照组在阴道分泌物的多样性、密集度、优势菌、pH、清洁度和病原体检出率等方面比较差异有统计学意义(Ps0.05)。宫腔粘连组阴道微生态失调检出率(48%)高于对照组(31%),差异有统计学意义(P0.05)。结论宫腔粘连患者阴道微生态失调发生率明显增高,阴道微生态失调可能与宫腔粘连的发生有关。     

Brazilian green propolis on Helicobacter pylori infection. a pilot clinical study

Recent in vitro studies suggest that propolis and some of its phenolic components are able to inhibit Helicobacter pylori growth. To date, there are no clinical studies. AIMS: To evaluate the effect of Brazilian green propolis on H. pylori-infected individuals. PATIENTS AND METHODS: Eighteen (11 females, 7 males, mean age 47 years) participants were included. Before treatment, all participants were submitted to gastroscopy, and H. pylori infection was confirmed by histology, urease test, and (13)C-urea breath test (UBT). Participants with UBT showing a delta over baseline (DOB) value higher than 4 per thousand were considered positive for H. pylori infection. Twenty drops from an alcoholic preparation of Brazilian green propolis were administered three times a day for 7 days. Clinical evaluation and UBT were performed at 1-3 days and at 40 days after the end of therapy to evaluate H. pylori suppression or eradication, respectively. RESULTS: All participants took all medication and completed the study. Eighty-three percent of the subjects did not succeed in suppressing or eradicating H. pylori. Two participants reached partial suppression after treatment, but became positive again at UBT performed 40 days after treatment. Another participant presented negative at UBT 40 days after treatment, not confirmed by a second UBT performed 100 days after treatment. CONCLUSIONS: Brazilian green propolis used in popular dose showed minimal effect on H. pylori infection. Larger studies with longer duration, larger dose, and different frequency of administration of propolis extract should be undertaken to define its role on H. pylori therapy.     

True vaginal prolapse in a bitch

Frequently, vaginal fold prolapse is the protrusion of edematous vaginal tissue into and through the opening of the vulva occurring during proestrus and estrus stages of the sexual cycle. True vaginal prolapse may occur near parturition, as the concentration of serum progesterone declines and the concentration of serum oestrogen increases. In the bitch, this type of true vaginal prolapse is a very rare condition.

This short communication describes a 5-year-old female, cross-breed dog in moderate condition, weighing 33 kg, with distocia and true vaginal prolapse. Abdominal palpation and transabdominal ultrasonography revealed live and dead foetuses in the uterine horns. One dead and four live fetuses were removed from uterus by cesarean section. The ovariohysterectomy was performed after repositioning the vaginal wall with a combination of traction from within the abdomen and external manipulation through the vulva. Re-occurrence of a vaginal prolapse was not observed and the bitch recovered completely after the surgical therapy.

Compared to other vaginal disorders, vaginal prolapse is an uncommon condition in the bitch. In the present case, extreme tenesmus arising from distocia may have predisposed to the vaginal prolapse. The cause of dystocia was probably the disposition of the first foetus. We concluded that the vaginal prolapse was the result of dystocia in the present case.
