Is Antihelminthics Necessary in Postoperative Treatment of Intraventricular Neurocysticercosis? A Systematic Review.

OBJECTIVE: Patients with intraventricular neurocysticercosis (IVNCC) may require cerebrospinal fluid diversion surgery for late-onset hydrocephalus in the postsurgical period. Controversy exists regarding cysticidal treatment. Our main objective was to compare surgically treated cases of IVNCC that received postoperative anthelmintics with those that did not regard the incidence and treatment of late-onset hydrocephalus. METHODS: We searched the Medline database and extracted the following data: age, gender, stage of development of cysticercosis, type of operation, frequency of delayed hydrocephalus, cerebrospinal fluid diversion surgery, outcome, and follow-up. RESULTS: We analyzed 130 articles on intraventricular cysticercosis and identified 117 cases of isolated IVNCC and 314 patients in the case-control series who met inclusion criteria. There was no significant difference in postoperative delayed hydrocephalus between isolated IVNCC and case-control study groups. Children under the age of 16 received anthelmintic drugs more frequently during the postoperative period. Statistical relevance was observed in all patient groups regarding the application of steroids in favor of cysticidal therapy Endoscopy was a better option than craniotomy for cases of isolated IVNCC and case-control studies. Other variables were not relevant. CONCLUSIONS: Patients who received antihelminths did not show a statistically significant reduction in delayed hydrocephalus compared to individuals who did not receive after surgical resection of the parasite. Corticosteroid therapy prevailed in people who have been treated with anthelmintics. Children under the age of 16 were administered anthelmintic drugs more frequently during the postoperative period. Endoscopy was the preferred method for all groups, but some patients with cysts in the fourth ventricle required a craniotomy.

Antifungal Activity and Type of Interaction of Melissa officinalis Essential Oil with Antimycotics against Biofilms of Multidrug-Resistant Candida Isolates from Vulvovaginal Mucosa.

(1) Background: Vulvovaginal candidosis (VVC) is a major therapy issue due to its high resistance rate and virulence factors such as the ability to form biofilms. The possibility of combining commonly used antifungals with natural products might greatly improve therapeutic success. (2) Methods: A total of 49 vulvovaginal isolates, causative agents of recurrent VVC, were tested for their susceptibility to fluconazole, nystatin, and Melissa officinalis essential oil (MOEO). This examination included testing the antibiofilm potential of antifungals and MOEO and the determination of their types of interaction with mature biofilms. (3) Results: Antimicrobial testing showed that 94.4% of the Candida albicans isolates and all the Candida krusei isolates were resistant to fluconazole, while all strains showed resistance to nystatin. The same strains were susceptible to MOEO in 0.156-2.5 mg/mL concentrations. Additionally, the results revealed very limited action of fluconazole, while nystatin and MOEO reduced the amount of biofilm formed by as much as 17.7% and 4.6%, respectively. Testing of the combined effect showed strain-specific synergistic action. Furthermore, the lower concentrations exhibited antagonistic effects even in cases where synergism was detected. (4) Conclusions: This study showed that MOEO had a very good antibiofilm effect. However, combining MOEO with antimycotics demonstrated that the type of action depended on the choice of antifungal drugs as well as the applied concentration.

Microfilaremic Dirofilaria repens Infection in Patient from Serbia.

We report a case of Dirofilaria repens infection causing microfilaremia in a patient from Serbia. Serum samples tested positive for D. repens IgG by ELISA. Our findings and those of others suggest the parasite's progressive adaptation to humans. Clinicians should be aware that microfilaremia can develop during Dirofilaria spp. infections.

Intraventricular Neurocysticercosis: Comparative Analysis of Different Localizations. Clinical Course and Treatment. A Systematic Review.

Background Neurocysticercosis is significant due to its high prevalence and considerable morbidity and mortality. The intraventricular form of NCC is less common than parenchymal, may have a rapidly progressive course and it requires a corresponding therapeutic response. Despite the extensive literature dealing with NCC and intraventricular cystic lesions, no systematic reviews have addressed similar work related to the clinical course and treatment of the infestation. Our main objective was to analyze the clinical type of the disease and the management for each ventricle separately on the basis of case reports or series of patients with individual data on the course of the disease and its treatment. As a control group, we used data on signs&symptoms and treatment of patients from published series on intraventricular neurocysticercosis. Method We performed a search in the Medline database. Google Scholar was also randomly searched. We extracted the following data from the eligible case/series: age and gender, symptoms, clinical signs, diagnostic examinations and findings, localization, treatment, follow-up period, outcome, and publication year. All data are presented in the form of absolute and relative numbers. The frequency of signs and symptoms, treatment and outcomes of the observed groups were checked by the Chi-square test and Fisher's test. The hypothesis was tested with p <0.05 as statistical significance. Results We selected 160 cases of intraventricular neurocysticercosis (IVNCC) and divided them according to their localization into five categories. Hydrocephalus was recognized in 134 cases (83.4%). Patients with isolated IVNCCare are younger (P=.0264) and have a higher percentage of vesicular cysts (p <.00001). In mixed IVNCC, degenerative and multiple confluent cysts predominate (p = 0.00068). Individuals carrying fourth + third ventricular cysts (potentially obstructive form) are younger than individuals with lateral ventricles (potentially less obstructive forme) (p = .0083). The majority of patients had individual symptoms for a longer period before the acute onset of the disease (p <.00001). The predominant clinical manifestation is headache (88.7%); the proportion within the groups ranged from 100% to 75% without statistical significance (p.074214). The same was true for patients with symptoms of vomiting or nausea, who had a lower and roughly balanced percentage of 67.7% to 44.4% (p.34702). Altered level of consciousness (ranging from 21% to 60%) and focal neurological deficit (from 51.2% to 15%) are the only clinical category with statistical significance (p <0.001 and p.023948 ). Other signs and symptoms were less frequent and statistically irrelevant. Surgical resection of the parasite was the predominant type of treatment, varying from 55.5% to 87.5% (p- .02395); endoscopy (48.2%) and craniotomy (24.4%), each individually, showed statistical significance (.00001 and .000073, respectively). The difference was also relevant among patients who had CSF diversion performance with/without medical treatment (p-.002312. Postoperatively, 31.8% of patients received anthelmintics with/without anti-inflammatory or other drugs. Endoscopy, open surgery, and postoperative antiparasitic therapy showed statistical differences (p < 0.001). Favorable outcomes or regression of symptoms were recorded in 83.7%, mortality 7.5%. In the case series, the clinical signs&symptoms were as follows: headache-64%, nausea and vomiting 48.4%, focal neurological deficit 33.6% and altered level of consciousness 25%. Open surgery was the predominant form of intervention (craniotomy (57.6% or endoscopy 31.8%); with statistical significance between them (p< .00001). Conclusion. Ventricular neurocysticercosis is an alarming clinical condition. Hydrocephalus is the dominant diagnostic sign. Isolated IVNCC patients were recognized at a younger age than Mix.IVNCC individuals; poeple with cysts in the fourth and third ventricles (as a potentially more occlusive type of disease), presented their symptoms at a younger age than individuals with LVNCC. The majority of patients had long-term signs and symptoms before the acute onset of the disease. Headache, nausea& vomiting are the most common symptoms of infestation accompanied by altered sensorium and focal neurological deficits. Surgery is the best treatment option. A sudden increase in ICP due to cerebrospinal fluid obstruction with a successive cerebral hernia is the leading cause of fatal outcomes.

Etiology, Predisposing Factors, Clinical Features and Diagnostic Procedure of Otomycosis: A Literature Review.

Otomycosis (OM) is a superficial fungal infection of the external auditory canal (EAC) with a worldwide prevalence ranging from 9% to 30%. Commonly, otomycoses are caused by Aspergillus (A.) niger complex and Candida spp. Other causative agents are yeasts of the genera Cryptococcus spp., Rhodotorula spp., Geotrichum candidum, dermatophytes (Trichophyton mentagrophytes), and non-dermatophytes molds (Fusarium spp., Penicillium spp., Mucorales fungi). The widest range of different species causing OM are found in the territories of Iran, India, China, Egypt, Mexico, and Brazil. Fungal infection of the EAC varies from mild to severe forms. It can be acute, subacute, or chronic, and is often unilateral, while the bilateral form is more common in immunocompromised patients. From an epidemiological point of view, tropical and subtropical climates are the most significant risk factor for the development of otomycosis. Other predisposing conditions include clothing habits, EAC hygiene practices, long-term antibiotic therapy, diabetes, and immunodeficiency. Since it is often difficult to distinguish otomycosis from an infection of a different origin, laboratory-based evidence, including standard procedures (microscopy and cultivation), is essential for diagnosis. For the treatment of this superficial fungal infection, there are no official therapeutic guidelines and protocols. However, many antifungals for local application, such as polyene, imidazoles, and allylamines, can be applied, as well as systemic antimycotics (triazoles) in severe forms of infection.

Prevention of Thelazia callipaeda Reinfection among Humans.

Thelazia callipaeda is a zoonotic vector-borne nematode that infects and causes eye disease among a wide range of domestic and wild mammals, including humans. We describe an unusual case of reinfection by this nematode in Serbia and call for a focus on preventive measures in endemic areas.

Relationship between socio-descriptive characteristics, burnout syndrome, and quality of life of employees.

Introduction: Burnout syndrome develops as a consequence of chronic stress among employees. The study objective was to examine what socio-descriptive characteristics of employees might be associated with the appearance of the occupational burnout and to evaluate the relationship between job burnout and the quality of life among security employees of the professional private security sector in Central Serbia. Methods: A multicenter cross-sectional questionnaire-based study was performed. A multivariate logistic regression analysis and ANOVA post choc test was applied. Results: A total of 353 respondents (330 male and 23 female) participated in the study. Female sex and older age were associated with a higher risk of total burnout and the development of emotional exhaustion while male sex, higher education, and managerial position were associated with higher personal achievement and lower risk of total burnout. Male sex, marital union, two or more children, and direct contact with clients were significantly associated with a lower quality of life of employees. A significant negative correlation was found between total burnout and the Physical Health Composite Score (PHC) score with a correlation coefficient (rs) of -0.265 (95%CI from -0.361 to -0.163); between total burnout and the and Mental Health Composite Score (MHC) score with a rs of -0.391 (95%CI from -0.480 to -0.301); and between total burnout and TQL score with a rs of -0.351 (95%CI from -0.445 to -0.258). Conclusion: Female sex and older age were associated with a higher risk of total burnout and the development of EE while a managerial position and higher education were protective factors in relation to the development of burnout. Male sex, marital union, two or more children, and direct contact with clients were significantly associated with a lower quality of life of the employees. Shift work significantly reduced the total quality of life, while managerial positions increased the quality of life.

Knowledge about HPV Infection and the HPV Vaccine among Parents in Southeastern Serbia.

Background and Objectives: The vaccine against human papilloma virus (HPV) infection is recommended, according to the Serbian National Immunization Program, for children and adolescents aged 9−19 years. Three doses are given keeping in mind the recommendation that the second dose should be administered at least one month after the first dose, and the third at least three months after the second dose. No children who participated in this first study received the third dose because they did not meet these criteria. The study explored parents' knowledge about HPV infection and their awareness of the HPV vaccine. Materials and Methods: A cross-sectional questionnaire-based study was carried out in the city of Nis, in southeastern Serbia. According to the 2011 population census, the sample of children aged 9 to 19 was 850, and during the observed period, 631 children received the vaccine. A total of 615 fully completed questionnaires filled out by parents were included in the study. The study was carried out from 6 June 2022 to 7 October 2022. Multivariable logistic regression analysis was used. The odds ratio (OR) and 95% confidence intervals (CI) were calculated. The statistical significance was p < 0.05. Results: A total of 615 children were included in the study (499 were vaccinated with the first dose and 116 with the second). Out of 499 children vaccinated with the first dose, 398 (79.6%) were girls, which is significantly higher than the rate for boys (101). The independent variable sex was statistically significant at the level of p = 0.84, OR = 2.664 (95% CI from 0.879 to 7.954). Boys are 164% less likely to be vaccinated with the HPV vaccine than girls. We determined that the independent variable place of residence was significant at the level of p = 0.041, (OR = 3.809, 95% CI from 1.702 to 8.525). Based on these findings, we determined that parents who came from rural areas were 82% less likely to know about HPV infection and HPV vaccination. Children under 15 years of age were significantly more vaccinated than those ≥15 years (OR = 3.698, 95% CI from 1.354 to 12.598). The independent variable parental education was significant at the level of OR = 0.494, 95% CI from 0.301 to 0.791. Parents who had medical education showed significantly higher awareness about the infection caused by HPV and about the HPV vaccine (p = 0.004) than parents with no medical education. The possibility that a parent would decide to vaccinate a child significantly increased upon a pediatrician's recommendation, p = 0.000 with OR = 0.250 (95% CI from 0.127 to 0.707). Health insurance coverage of HPV vaccination for children aged 9−19 years significantly increased the probability of a positive parental decision to vaccinate a child, p = 0.001 with OR = 3.034 (95% CI from 1.063 to 8.662). Conclusion: We identified several significant factors that were important for HPV vaccination such as: children under 15 years, female sex, urban place of residence, medical education of parents, pediatrician's recommendation of the HPV vaccination, and HPV vaccination free of charge. Health education and the promotion of HPV vaccination as well as healthy sexual behavior are important factors in the preservation and improvement of the health of the whole population.

Poly(methyl methacrylate) with Oleic Acid as an Efficient Candida albicans Biofilm Repellent.

Poly(methyl methacrylate) (PMMA), widely used in dentistry, is unfortunately a suitable substrate for Candida (C.) albicans colonization and biofilm formation. The key step for biofilm formation is C. albicans ability to transit from yeast to hypha (filamentation). Since oleic acid (OA), a natural compound, prevents filamentation, we modified PMMA with OA aiming the antifungal PMMA_OA materials. Physico-chemical properties of the novel PMMA_OA composites obtained by incorporation of 3%, 6%, 9%, and 12% OA into PMMA were characterized by Fourier-transform infrared spectroscopy and water contact angle measurement. To test antifungal activity, PMMA_OA composites were incubated with C. albicans and the metabolic activity of both biofilm and planktonic cells was measured with a XTT test, 0 and 6 days after composites preparation. The effect of OA on C. albicans morphology was observed after 24 h and 48 h incubation in agar loaded with 0.0125% and 0.4% OA. The results show that increase of OA significantly decreased water contact angle. Metabolic activity of both biofilm and planktonic cells were significantly decreased in the both time points. Therefore, modification of PMMA with OA is a promising strategy to reduce C. albicans biofilm formation on denture.

Adolescent Scalp Dermatitis Associated with Dermatophagoides spp. (Acariformes; Pyroglyphidae) Mite.

PURPOSE: Dermatophagoides spp. (Acariformes; Pyroglyphidae), house dust-mite well known as the causative agent of atopic hypersensitivity and allergy could potentially cause severe dermatitis. Herein we report an uncommon case of scalp dermatitis associated with the presence of Dermatophagoides spp. METHODS: A 17-year old male presented with patchy alopecia on the scalp without intense peeling or itching, surround by unchanged skin and hair. Initially, superficial fungal infection was suspected; however, parasitological examination revealed the presence of live mites. RESULTS: All the anatomical measurements and parameters from the specimens were compatible with Dermatophagoides spp. CONCLUSIONS: Dermatophagoides spp. are not yet confirmed as causative agents of parasitic infestation, but the presence of these mites could have caused an allergic reaction followed by dermatitis with mild-to-moderate clinical manifestations. However, true parasitism as well as phoresy could also be considered. The clinical manifestations caused by house-dust mite cannot be easily recognized and the lack of diagnostic tools is a hindrance that often leads to misdiagnosis and inadequate therapy.

A case of mycotic keratitis due to Fusarium sp. with an undesirable outcome.

Fungal keratitis, an infective disease of the cornea, represents a serious diagnostic and therapeutic problem that, if not recognized on time, could lead to irreversible eye damage. Herein we report a case of fungal keratitis due to Fusarium spp. infection. The 60-year-old man was admitted to our clinic due to an atraumatic acute onset of the disease, with a decrease in the visual acuity, photophobia, redness, and severe pain in the right eye. Clinical observation revealed an ulcer that affected 1/3 of the cornea and a hypopion in the anterior chamber. After the first results of microbiological analyzes, local and systemic antifungal therapy was applied. Due to the fact that the patient voluntarily left the treatment, there was a drastic worsening of the local findings as a full thickness total corneal infiltrate with more intense anterior chamber reaction. Finally, evisceration was performed. Given the fact that fungal keratitis is more prevalent in developing countries, official protocols and available effective antifungals are crucial for adequate treatment and a favorable outcome of this infection.

Molecular Survey of Dirofilaria and Leishmania Species in Dogs from Central Balkan.

Dirofilariosis and leishmaniosis are severe parasitic diseases in dogs, and their causative agents can also be pathogenic to humans. In this study, we conducted a multicentric survey in the regions of Serbia and North Macedonia with the goal to establish an epidemiological scenario of dirofilariosis and leishmaniosis in the territory of Central Balkan. Using molecular analyses, a total of 535 dogs from Northern Serbia (NS), Southern Serbia (SS) and North Macedonia (NM) were screened for the presence of Dirofilaria spp. and Leishmania spp. We confirmed that Central Balkan is an endemic region for Dirofilaria (D.) immitis, as it was found to be the dominant species in this area, with the highest prevalence of 8.75% in NM, followed by NS (6.68%) and a significantly lower prevalence in SS (1.51%). Two dogs (2.5%) from NM were positive for Leishmania (L.) infantum infection. None of the dogs from Serbia tested positive for Leishmania spp. High prevalence and dominance of D. immitis species, and the rising threat of L. infantum spread to the territory of Serbia, suggest that preventive measures are of a great necessity to combat the spread of these vector-borne zoonoses.

Clinical Presentations, Cluster Analysis and Laboratory-Based Investigation of Aspergillus Otomycosis-A Single Center Experience.

Species of Aspergillus (A.) niger complex and A. flavus complex are predominant molds that are causative agents of otomycoses. The goal of this study was to investigate the clinical presentation, diagnostic procedure, and appearance of relapse in patients with Aspergillus-otomycosis, as well as to determine the biofilm production ability of species isolated in relapse. Thirty patients with laboratory evidenced Aspergillus-otomycosis followed by two check-ups (30 and 60 days after initiation of treatment with antimycotics for local application) were included in the study. For isolation and identification of Aspergillus spp. the standard mycological procedure was applied. Results showed very high sensitivity of microscopy, but 16.7% Aspergillus species required the optimal temperature of 27-28 °C for cultivation. Applied statistical cluster analysis showed a defined specific cluster/group of patients with A. niger complex-otomycosis. Sixty days after diagnosis and treatment initiation, six patients had a relapse, with the same species of Aspergillus genus being the cause. To establish the ability of biofilm production, the modified method described by Pierce and Kvasnicková was performed, and all six species isolated in the relapse episode had the ability to produce biofilm. Official criteria and recommendations are needed due to the possibility of misdiagnosis, which leads to the prolongation and complication of the disease.

Cancer of unknown primary - incidence, mortality trend, and mortality-to-incidence ratio is associated with human development index in Central Serbia, 1999-2018: Evidence from the national cancer registry.

OBJECTIVES: The aim was to estimate the trend of incidence, mortality and mortality-to-incidence ratio (MIR) in Central Serbia in 1999-2018 and its possible association with the human development index (HDI). METHODS: In this study, cancer of unknown primary (CUP) was included as C77-C80 codes. Trend analysis was performed in the Joinpoint Regression Programme version 4.8.0.1. HDI combines life expectancy, educational attainment and gross national income. HDI values for Serbia are extracted from the global bank site. RESULTS: Joinpoint regression analysis of the age-standardised incidence rate of CUP showed a significantly increasing trend with annual percent change (APC) of 8.5% (95% confidence interval [CI] 3.0-14.3%) in males and 7.8% (95%CI 2.7-13.2) in females. The age-standardised mortality rate of CUP showed a significantly decreasing trend with APC of -1.7% (95%CI -2.8 to -0.5%) in males and -1.4% (95%CI -2.7 to -0.1%) in females. MIR showed a significantly decreasing trend with APC of -9.3% (95%CI -14.6 - -3.6%) in males and -7.1% (95%CI -10.5% to -4.2%) in females. The linear regression showed significant inverse association among HDI and the MIR of CUP in males (r2 = 0.464, p = 0.002) and in females (r2 = 0.612, p < 0.001). CONCLUSIONS: Decline of MIR was associated with HDI, suggesting that CUP prognosis follows socio-economic status.

New cases of human dirofilariosis on the Balkan Peninsula - "Masked intruders" uncovered by a surgeon.

Dirofilaria spp. nematodes are accidental parasites of humans causing mild to serious, superficial or visceral infections. Superficial dirofilariosis is rather common in Europe and is typically manifested as subcutaneous form. Herein we report 46 new cases of human dirofilariosis (19 patients with subcutaneous, 18 patients with ocular, 4 patients wih genital, 2 patients with submucosal, 2 patients with pulmonary and 1 patient with intramuscular form of infection) that were recorded from the beginning of 2015 to May 2021 on the Balkan Peninsula with a goal to update the prevalence of this parasitosis and point out potential problems in diagnosis and treatment. Besides, given the high possibility of misinterpretation as tumor, our second aim was to encourage the inclusion of this pathogen in the differential diagnosis of subcutaneous nodules. Although quite common forms, subcutaneous and ocular dirofilariosis can be very often misdiagnosed in clinical practice due to the absence of specific clinical manifestations. Therefore, raising awareness of clinicians about this zoonosis is needed as well as closer collaboration between physicians and veterinarians.

Health-Related Quality of Life in Stroke Survivors in Relation to the Type of Inpatient Rehabilitation in Serbia: A Prospective Cohort Study.

Background and objectives: Health-related quality of life after stroke is an important public health issue. The objective of the study was to investigate the relationship between the perceived health-related quality of life in stroke survivors in relation to the type of inpatient rehabilitation. Materials and Methods: Using a random selection method out of a total of 688 patients, every fourth survivor who had a stroke in the period from 1 January 2017 to 31 December 2019 was selected from the admission protocol of the Clinic for Rehabilitation and Physical Medicine of the Clinical Centre Nis, Serbia. A total of 160 first-ever stroke survivors were included (80 underwent additional inpatient rehabilitation and 80 underwent only inpatient rehabilitation in a tertiary health institution) in a twelve-month prospective study. The EuroQuol-5 Dimension (EQ5D) questionnaire and Stroke Impact Scale were used for the assessment. Multivariate linear regression analysis was done. Results: Multivariate linear regression analysis showed that additional inpatient rehabilitation from six up to eight weeks after discharge was significantly associated with better self-reported health condition by 3.9 times (from 1.9 to 8.2), significantly decreased the ranks of EQ5D by 1.78 times (from 1.02 to 3.11), and showed a higher health-related quality of life. We determined a significant increase of strength, emotions, mobility, and participation role in survivors who underwent additional inpatient rehabilitation compared with those who did not. Conclusions: There was a significant difference in health-related quality of life perceived by stroke survivors who underwent additional hospital rehabilitation in relation to those who underwent only inpatient rehabilitation.

Seroepidemiological Study of Canine and Human Dirofilariasis in the Endemic Region of Northern Serbia.

Dirofilariasis is a vector-borne zoonotic disease caused mainly by Dirofilaria immitis and Dirofilaria repens that affect dogs and humans all over the world. Serbia is considered an endemic country to both forms of dirofilariasis, although most of the population is concentrated in the north of the country. The aims of this study were to show the prevalence of D. immitis and D. repens in dogs and the seroprevalence in humans compared to previous studies in Northern Serbia. In total, 346 dog sera samples and 265 human samples were analyzed. Dog blood samples were analyzed using the modified Knott's method to check whether there were Dirofilaria spp. microfilariae and serum samples were checked by a commercial D. immitis antigen test. Human serum samples were analyzed with a non-commercial ELISA for detection of specific anti-D. immitis, anti-D. repens, and anti-Wolbachia IgG antibodies, and confirmed by western blotting. The overall prevalence for Dirofilaria spp. in dogs was 29.19%. The overall prevalence for D. immitis was 26.30%. The percentages of D. immitis and D. repens microfilaremia in dogs were 25.72 and 1.45%, respectively, while D. immitis./D. repens microfilaremia co-infections were also 1.45%. The overall seroprevalence for Dirofilaria spp. in humans was 3.77%. The overall seroprevalence for D. immitis was 1.51, 1.13% for D. repens, and for D. immitis/D. repens co-infections was 1.13%. The results indicate that D. immitis and D. repens are present in dogs and humans in the province of Vojvodina, in the northern part of Serbia. It is most likely associated with the presence of many rivers, the climate, and presence of mosquitoes in the area, so there could be a real public health risk.

Knowledge about Cervical Cancer and Awareness of Human Papillomavirus (HPV) and HPV Vaccine among Female Students from Serbia.

Background and objectives: Persistent infection with carcinogenic human papillomavirus (HPV) is the leading cause of cervical cancer. The study explored students' knowledge about cervical cancer and awareness of human papillomavirus and the HPV vaccine. Materials and Methods: A questionnaire-based survey was carried out among 1616 first-year female college students at the University of Nis. It examined socio-demographic characteristics, measured the score of knowledge about cervical cancer, assessed awareness regarding HPV and the HPV vaccine and inquired about the source of information about cervical cancer and HPV. Results: The average cervical cancer knowledge score was 16.35 ± 7.92 (min 0, max 30), with medical professional education, parents' education level, place of residence and relationship status having significant effects on the score. The awareness about HPV and the HPV vaccine was low, with only 14.2% of students having heard about both HPV and its vaccine. The most commonly reported sources of information were the media, while the most competent one was organized health education. Conclusions: Health promotion campaigns and educational programs are necessary in order to reduce cervical cancer burden and should be directed particularly towards those who have demonstrated low cervical cancer knowledge and low awareness regarding HPV and its vaccine.

Recurrent Vulvovaginal Candidosis and Cluster Analysis of Clinical Signs and Symptoms: A Laboratory-Based Investigation.

Recurrent vulvovaginal candidosis (RVVC) represents a major health problem that significantly affects a patient's quality of life (QoL). This infection presents with a plethora of clinical manifestation, and this is the first study that carries out a cluster analysis of these signs and symptoms (SS). The goals are to evaluate the distribution of species causing RVVC, their in-vitro susceptibility to antifungals, and the patient's QoL. Additionally, the clinical characteristics are analyzed using cluster analysis. Prospective analysis of data was performed for women diagnosed with RVVC in the period from January 2016 to December 2019 based on the analysis of data from a single-center's records. The standard mycological methods and antifungal susceptibility testing were done. Clinical characteristics and QoL were examined by appropriate questions. The cluster analysis was used to identify clusters of SS. A total of 320 women were diagnosed. The dominant species was Candida (C.) albicans. Non-albicans Candida (NAC) yeast was found in 24.4%, and the most common was C. glabrata. Interestingly, Saccharomyces (S.) cerevisiae was detected in 2%. All of the isolated species, except C. parapsilosis and C. kefyr, demonstrated reduced susceptibility to antifungals. We confirmed the emergence of the NAC species and S. cerevisiae with reduced susceptibility to antifungals. Cluster analysis represented by a dendrogram revealed three SS clusters: irritation, uncommon, and discharge, but further studies are needed to examine the relationship between clusters, Candida strains, and outcomes.
