[PMID: 38373939 PMCID: PMC10875808 DOI: 10.1186/s12879-024-09065-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2023] [Accepted: 01/27/2024] [Indexed: 02/21/2024] Open
Abstract
BACKGROUND Oral candidiasis is a common opportunistic infection in patients with human immunodeficiency virus (HIV). In addition, most of these patients suffer from vitamin D deficiency. This study aimed to investigate the association between vitamin D levels and oral candidiasis in patients with HIV infection. METHODS This case‒control study was conducted on HIV-infected patients. Cases were patients with oral candidiasis diagnosed based on physical examinations. Controls were age- and sex-matched individuals without oral candidiasis. The levels of 25-OH vitamin D and other laboratory markers (CD4 count and viral load) were compared between the case and control groups. RESULTS A total of 104 cases and 102 controls were included in the study. The cases had significantly lower 25-OH vitamin D3 levels (MD = 33.86 ng/mL, 95% CI= (31.85, 35.87), P < 0.001) and CD4 counts (MD = 267.48 cells/mm3, 95% CI= (189.55, 345.41), P < 0.001) than the controls. In addition, viral load was significantly higher in cases than in controls (MD = 7.03 × 105 copies/mL, 95% CI= (4.46 × 105, 9.61 × 105), P < 0.001). The multivariate logistic regression analysis revealed that educational status (OR = 0.032, 95% CI= (0.002, 0.100), P < 0.001), current HAART (OR = 0.005, 95% CI= (0.001, 0.014), P < 0.001), history of oral candidiasis (OR = 20.114, 95% CI= (18.135, 21.957), P < 0.001), CD4 count (OR = 0.004, 95% CI= (0.001, 0.006), P < 0.001), viral load (OR = 12.181, 95% CI= (1.108, 133.392), P < 0.001), and vitamin D level (OR = 0.011, 95% CI= (0.008, 0.015), P < 0.001) were significantly associated with the risk of developing oral candidiasis. CONCLUSIONS Based on the findings, most patients with HIV infection suffer from vitamin D deficiency, especially those with oral candidiasis. Hypovitaminosis D was significantly associated with an increased risk of oral candidiasis. Thus, vitamin D supplementation may assist HIV-positive patients in improving their oral health and preventing oral candidiasis.

Management of Chronic Atrophic Candidiasis (Denture Stomatitis)-A Narrative Review. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2023; 20:3029. [PMID: 36833718 PMCID: PMC9967389 DOI: 10.3390/ijerph20043029] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 01/01/2023] [Revised: 02/02/2023] [Accepted: 02/07/2023] [Indexed: 06/18/2023]
Abstract
One of the most common oral diseases affecting people wearing dentures is chronic atrophic candidiasis or denture stomatitis (DS). The aim of the paper is to provide an update on the pathogenesis, presentation, and management of DS in general dental practice settings. A comprehensive review of the literature published in the last ten years was undertaken using multiple databases, including PubMed via MEDLINE, EMBASE, and Scopus. The eligible articles were analyzed to identify evidence-based strategies for the management of DS. Despite its multifactorial nature, the leading cause of DS is the development of oral Candida albicans biofilm, which is facilitated by poor oral and denture hygiene, long-term denture wear, ill-fitting dentures, and the porosity of the acrylic resin in the dentures. DS affects between 17 and 75% of the population wearing dentures, with a slight predominance in elderly females. The mucosal denture surfaces and posterior tongue are the common sites of DS, and the affected areas exhibit erythema, the swelling of the palatal mucosa and edema. Oral and denture hygiene protocols, adjusting or re-fabricating poorly adapting dentures, smoking cessation, avoiding nocturnal denture wear, and the administration of topical or systemic antifungals are the mainstay of management. Alternate treatments such as microwave disinfection, phytomedicine, photodynamic therapy, and incorporation of antifungals and nanoparticles into denture resins are being evaluated for the treatment of DS but require further evidence before routine use in clinical practice. In summary, DS is the most common oral inflammatory lesion experienced by denture wearers. Most patients with DS can be managed in general dental practice settings. Effective management by general dental practitioners may be supported by a thorough understanding of the pathogenesis, the recognition of the clinical presentation, and an awareness of contemporary treatment strategies.

Enzyme production by Candida albicans and Candida dubliniensis in periodontal HIV-positive patients receiving and not receiving antiretroviral therapy. ACTA ODONTOLOGICA LATINOAMERICANA : AOL 2020; 33:104-111.

Abstract
Candida dubliniensis (Cd) and Candida albicans (Ca) are the most frequently isolated yeasts in HIV+ patients. Some of the enzymes produced by these yeasts are considered virulence factors since they contribute to pathogenicity of Candida spp. The aim of the present study was to compare production of enzymes such as phospholipase (Ph), proteinase (P), and hemolysin (H) by Cd and Ca strains isolated from periodontal HIV-positive patients receiving and not receiving highly active antiretroviral therapy (HAART). Subgingival biofilm samples were obtained using paper points, and a sample of oral mucosa was taken using a swab. Phenotypic and molecular methods were used to isolate 39 strains of Candida, including 25 strains of Cd and 14 strains of Ca, obtained from 33 periodontal pocket samples and 6 oral mucosa samples collected from 15 HIV+ patients (8 receiving and 7 not receiving HAART). Malt egg-yolk agar, albumin agar and blood agar were used to evaluate pH, P and H production respectively. The strains were inoculated in duplicate and incubated at 37 ºC. Colony and halo diameters were measured. A greater proportion of Ca was observed in patients not receiving HAART, and a higher proportion of Cd was observed in those under HAART, Chi2 p< 0.001. Phospholipase production was observed in 92.9% percent of isolated Ca strains but in none of the isolated Cd strains. Proteinase production was high in Ca and Cd strains isolated from patients not receiving HAART. Hemolysin production was observed in all the studied strains, though it was significantly higher (p=0.04) in Ca and Cd strains isolated from patients not receiving HAART. To sum up, the proportion of Candida dubliniensis strains was highest in the subgingival biofilm of patients receiving HAART, and Cd strains were found to express fewer virulence factors than Ca strains.

Abstract
Oral candidiasis infection is generally treated with antifungal agents. However, it often requires long-term treatment, and epithelial dysplasia may persist even after the infection has been resolved depending on the case. Malignant transformation has been reported in long-term cases involving chronic inflammation, and surgical excision should be performed as the treatment of choice when the treatment period is prolonged. This report describes a case of maxillary gingival carcinoma caused by chronic inflammation related to oral candidiasis. The patient was an 85-year-old man who was admitted to our hospital with maxillary gingival pain. Cytology and biopsy revealed oral candidiasis and squamous cell carcinoma(cT1N0M0, Stage Ⅰ). He underwent partial maxillectomy. Post-operative recovery was uneventful, and there was no sign of recurrence or metastasis at the 1-year follow-up.

Abstract
Aim of this paper is to give an overview about topical and systemic therapy options for the oral candidiasis. The clinical presentation of oral candidiasis is mostly white, easily wiped off coatings or erythematous efflorescences, with several subtypes. Antifungal therapy is indicated in case of clinical symptoms or as prevention for immune-compromised patients. In addition, local or systemic factors should be revealed and improved. An appropriate oral hygiene is essential for the treatment and prevention of possible reinfection.

Abstract
Candida species are commensal yeasts of the oral cavity, which, under predisposing systemic and/or local circumstances, are responsible for a wide variety of clinical manifestations, globally known as oral candidiasis. Candida-associated denture stomatitis is an oral candidiasis particularly affecting the oral mucosa covered by a dental prosthesis, with several degree of severity. Diabetics suffer oral candidiasis more frequently than healthy individuals do and if they are denture wearers, the risk increases. Since various controversies still remain regarding the interrelationship among diabetes, oral Candida spp. strains involved in denture stomatitis and the presence of dentures, the present review aims to investigate the differences in Candida species frequencies and degree of denture stomatitis severity existing among diabetic and non- diabetic individuals, with and without dentures.

Abstract
OBJECTIVES The aim of this cross-sectional observational study was to compare the prevalence of different oral Candida spp. in patients with Type 2 Diabetes and chronic periodontitis in two oral sites: dorsal surface of the tongue and subgingival area. In order to determine subgingival areas as potential reservoirs of yeasts, this study aimed to find differences in the yeasts' detection between the dorsum of the tongue, as the oral site most commonly inhabited with microorganisms, and subgingival samples. Additionally, potential predictors for the yeasts prevalence were determined. MATERIAL AND METHODS Subjects (N = 146) were divided into four groups: group A- healthy individuals without periodontitis, group B- healthy individuals with chronic periodontitis, group C- Type 2 Diabetes patients with good glycoregulation and Chronic periodontitis and group D- Type 2 Diabetes patients with poor glycoregulation and Chronic periodontitis. Samples were obtained from the tongue by swabbing. Subgingival plaque samples were taken by paper points and periodontal curette. Isolation and identification of different Candida spp. was done using ChromAgar medium. In addition, germ-tube production and carbohydrate assimilation tests were performed. RESULTS The prevalence of Candida spp. was higher in diabetics with poor glycoregulation. The most frequently isolated species was Candida albicans followed by Candida glabrata and Candida tropicalis. In 15.6% of cases, Candida spp. was present in the subgingival area while absent on the tongue. Multivariate regression model showed that HbA1c was Candida spp. predictor for both locations. CONCLUSIONS Our results confirmed that there are Candida spp. carriers among subjects with clinically healthy oral mucosa. Also, this study identified subgingival areas as potential reservoirs of these pathogenic species. Glycoregulation has been recognized as a positive predictor factor of Candida spp.

Abstract
We present a case of a suspect splenic hematoma in an anticoagulated patient with an ignored diabetes mellitus, come to our emergency department. Lab tests showed increased CRP and INR, with an incoming hepatorenal syndrome. During the CT-scan the patient became unstable and the hemoglobin decreased. We decided for an emergency explorative laparotomy finding instead purulent collections with no evidence of bleeding, so we drained the pus and performed a splenectomy. After we excluded all the common primary sites of infection, we found out a severe chronic parodontopathy caused by multiple colonies of Candida albicans.

Abstract
PURPOSE The purpose of this study was to assess whether there is an association between oral thrush or other Candida-related conditions in infancy and early childhood caries (ECC) diagnosed by pediatricians. METHODS We conducted a retrospective cohort study using electronic health records from six national children's hospitals that participate in the PEDSnet research network. There were 1,012,668 children with a visit at ages one to 12 months and another visit at ages 13 to 71 months. The independent variables were diagnosis of thrush or Candida-related conditions in the first year of life, while the dependent variable was diagnosis of ECC between 13 to 71 months old. RESULTS Oral thrush detection was strongly associated with ECC, particularly between 13 and 36 months (rate ratio between 2.7 [95 percent confidence interval (95% CI) equals 2.5 to 2.9; P<.001] and 3.0 [95% CI, equals 2.8 to 3.4; P<.001]). A similar trend was observed with other Candida-related conditions. CONCLUSIONS Oral thrush may be a risk factor for early childhood caries.

Abstract
INTRODUCTION Acute esophageal necrosis, also known as black esophagus, is a rare digestive complication, frequently manifested by an upper gastrointestinal hemorrhage and occurs in patients with comorbidities. AIM To report the case of a patient with a black esophagus revealed by an upper gastrointestinal hemorrhage. OBSERVATION A 72-year-old patient with a history of diabetes mellitus, hypertension and ischemic heart disease was hospitalized in surgical intensive care unit for hemorrhagic shock induced by cholecystectomy. On the 7th postoperative day, the patient developed acute hematemesis. Gastroscopy showed circumferential necrosis, localized in the middle and lower third of the esophagus and stopped abruptly at the gastroesophageal junction. Gastric mucosa was strictly normal. The bulb and the first part of duodenum showed multiple superficial ulcers without signs of recent hemorrhage. The patient was placed on absolute diet and total parenteral nutrition associated with high-dose intravenous proton pump inhibitor. Second-look gastroscopy, performed six days later, showed a significant improvement in esophageal lesions. The evolution was marked by the occurrence of pneumonia complicated by septic shock which caused patient's death. CONCLUSION Black esophagus is a rare pathology of multifactorial etiology. Treatment is based on proton pump inhibitors in combination with resuscitation measures to control comorbidities. Mortality remains high due to the seriousness of comorbid disease states often associated with this condition.

Abstract
HIV infection is a major global health problem affecting developing and developed countries alike. Oral lesions that are associated with this disease are important, since they affect the quality of life of the patient and are useful markers of disease progression and immunosuppression. Oral lesions in HIV infection have been well-documented in developed countries, but there are fewer reports on oral lesions from developing countries. Oral candidiasis is the most common opportunistic infection seen in all continents. Kaposi’s sarcoma has been reported only from Africa and Latin America, while histoplasmosis and penicilliosis were reported in patients with advanced disease from Thailand. HIV-associated salivary gland disease has a high prevalence in Africa and Latin America, especially in the pediatric group. It is clear that there are considerable regional variations in the oral manifestations of HIV infection, depending both on the populations studied and on the clinical expertise available, among other factors. Well-designed and -documented studies are necessary for the correct assessment of the nature and magnitude of the problem in developing countries, if oral health measures are to be effectively formulated for the HIV-infected.

Abstract
The epidemiology of HIV-related oral disease in industrialized nations has evolved following the initial manifestations described in 1982. Studies from both the Americas and Europe report a decreased frequency of HIV-related oral manifestations of 10–50% following the introduction of HAART (highly active antiretroviral therapy). Evidence suggests that HAART plays an important role in controlling the occurrence of oral candidosis. The effect of HAART on reducing the incidence of oral lesions, other than oral candidosis, does not appear as significant, possibly as a result of low lesion prevalence in industrialized countries. In contrast to other oral manifestations of HIV, an increased prevalence of oral warts in patients on HAART has been reported from the USA and the UK. HIV-related salivary gland disease may show a trend of rising prevalence in the USA and Europe. The re-emergence of HIV-related oral disease may be indicative of failing therapy. A range of orofacial iatrogenic consequences of HAART has been reported, and it is often difficult to distinguish between true HIV-related oral disease manifestations and the adverse effects of HAART. A possible association between an increased risk of oral squamous cell carcinoma and HIV infection has been suggested by at least three epidemiological studies, with reference to the lip and tongue. These substantial and intensive research efforts directed toward enhancing knowledge regarding the orofacial consequences of HIV infection in the industrialized nations require dissemination in the wider health care environment.

Abstract
The workshop addressed the following questions with respect to periodontal diseases and bacterial infections seen in HIV infection: (1) What is linear gingival erythema? Is it prevalent only in HIV disease? A crude Delphi technique was used to ascertain whether LGE existed, but a consensus could not be reached. It was agreed that a diagnosis of LGE should be considered only if the lesion persists after removal of plaque in the initial visit. (2) Do periodontal pockets contribute to viremia in HIV infection? At present, the data are not available to answer this question. (3) Do anti-viral drugs reach the sulcular fluid in significant concentrations? No one at the workshop was aware of data that could answer this question. (4) Does concurrent tuberculosis infection modify the oral manifestations of HIV infection? Though analysis of data from the developing countries does suggest an association between tuberculosis and oral candidiasis, more data and multivariate analysis considering immunosuppression as a confounding factor are necessary, for any conclusions to be derived. (5) What pathogens are involved in periodontal diseases in HIV infection? Periodontal disease may be initiated by conventional periodontal pathogens. But the progression and tissue destruction depend upon the presence of typical and atypical micro-organisms, including viruses, their by-products, increased secretion of potentially destructive inflammatory mediators, and overwhelming host response. (6) How can we diagnose the diseases seen in HIV infection? The answer can be obtained only with data from controlled and blinded studies. It is necessary to design collaborative multi-center longitudinal studies. The results obtained from such large sample sizes can contribute eventually to interpretation of the outcome.

Abstract
Superficial fungal infection of the mucous membranes (thrush) isolated to the larynx is neither widely reported nor well recognized clinically. Therefore, it is often associated with ineffective treatment and delay in diagnosis, and sometimes associated with unneeded surgical intervention. Eight cases of thrush isolated to the larynx, with no oral or oropharyngeal manifestations, are presented. Four of these were isolated to the vocal folds alone. All patients were adults, and 4 were smokers. Hoarseness was always present. Pain was present inconsistently, and there was no dysphagia or odynophagia, in contrast to other forms of upper aerodigestive tract candidiasis. On average, diagnosis was not made until 6 months after the onset of symptoms. Possible causative factors included use of systemic steroids (3 cases), broad-spectrum antibiotics (1 case), or inhaled steroids (5 cases); diabetes (2 cases); and neutropenia (1 case). In 3 cases, all with thrush isolated to the vocal folds, inhaled steroids were the only causative factor identifiable — a feature reported only twice previously. Three patients underwent surgical procedures that might have been avoided had an accurate diagnosis been made. All patients responded readily to oral fluconazole and removal of predisposing factors where possible. The signs, symptoms, predisposing factors, and treatment are compared to those of 14 cases reported in the literature over 35 years.

Abstract
A 16-year-old girl with vertical HIV disease treated since birth suffered from six different AIDS-defining disorders until now. Even during the highly active antiretroviral therapy, multiple AIDS-related opportunistic infections may complicate the course of long-term congenital HIV disease, showing a strict relationship with immunological deterioration, which occurs shortly after virologic failure, due to an extensive genotypic resistance to all available antiretroviral compounds.

Abstract
BACKGROUND/AIM Dermatologic findings differ among countries but no sufficient data about Turkish HIV-infected patients exist in the literature. Therefore, our aim in this study was to document the dermatologic manifestations and their relationships with CD4 cell counts among HIV/AIDS patients visiting our clinic for the first time in Istanbul, Turkey. MATERIALS AND METHODS A retrospective analysis of 306 HIV/AIDS patients (260 men, mean age: 38.3 years) was done in a tertiary hospital in Istanbul from January 2006 to September 2012. Information on age, sex, transmission routes, socioeconomic and educational status, CD4 counts, and dermatologic findings was collected retrospectively from medical records. RESULTS Our analyses revealed at least 1 dermatologic disease in 111 of the 306 (36.2%) patients. Mean CD4 count of the patients was 393.64 cells/mm3 (range: 4-1270 cells/mm3). Oral candidiasis (12.4%), herpes zoster (5.9%), dermatophytosis (5.4%), hyperpigmentation (5.2%), and folliculitis (4.6%) were the most common skin problems. Statistically significant correlation (P < 0.05) with low CD4 cell counts was found for oral candidiasis, folliculitis, herpes zoster, hyperpigmentation, xerosis, and Kaposi's sarcoma. CONCLUSION Dermatologic manifestations in this study were identical to those described in most studies from Asia, and there were more manifestations as the HIV infection progressed and immune functions declined.

Abstract
OBJECTIVE This study presents the clinicopathologic features of a series (N = 35) of patients with non-human immunodeficiency virus (HIV)-associated oral hairy leukoplakia (OHL). METHODS Patients with non-HIV-associated OHL were identified from three centers. Epstein-Barr virus infection was demonstrated by using EBV early ribonucleic acid in situ hybridization. The presence of Candida co-infection was evaluated by diastase periodic acid-Schiff staining. The clinical features were determined by review of the medical records. RESULTS Twenty-eight patients had intercurrent respiratory problems requiring long-term steroid inhaler use, four suffered from autoimmune diseases requiring immunosuppressant therapy, and four had diabetes. The majority of lesions were located on the tongue, and 24 showed evidence of Candida co-infection. CONCLUSIONS In the twenty-first century, the presence of OHL should not be regarded as pathognomic for HIV infection or significant systemic immunosuppression. Local and systemic immunosuppression, in the form of steroid inhaler use, is a risk factor for the development of OHL.

Oral yeast samples were collected from 150 individuals: group A was 43 patients with prediabetes (fasting blood glucose levels and hemoglobin A1c, 100 to 125 mg/dL and ≥5%, respectively); group B was 37 individuals previously considered prediabetic but having fasting blood glucose levels <100 mg/dL and hemoglobin A1c <5%; and group C was 70 medically healthy individuals. Oral yeasts were identified using standard techniques. Unstimulated whole salivary flow rate and number of missing teeth were recorded. RESULTS Oral Candida was isolated from 100% of patients with prediabetes and from 65.7% of control participants. Candida albicans carriage was higher among patients with prediabetes (48.7%) (P < .01) and patients in group A (51.2%) (P < .01) than among controls (25.7%). Candida carriage, unstimulated whole salivary flow rate, and number of missing teeth were similar in groups A and B. CONCLUSIONS Oral Candida carriage was higher in patients with prediabetes than in controls and was independent of glycemic status in patients with prediabetes.

Abstract
OBJECTIVE To assess the incidence of oral candidiasis and its influencing factors in patients with human immunodeficiency virus infection/acquired immunodeficiency syndrome (HIV/AIDS). METHODS An oral examination was conducted in the 1 566 HIV/AIDS patients in the Third Hospital of Kunming from March 2008 to September 2012 (M/F: 1 062/504, age range: 0.2 to 84.0 years old). The HIV viral load (HIV- RNA) and peripheral blood CD4 count were respectively analyzed by Bayer Q340 fluorescence signal surveying instrument (bDNA method) and flow cytometry analysis. The information on usage of highly active anti-retroviral (HAART) drugs and transmission of HIV were obtained through questionnaires. The incidence of oral candidiasis in patients with different HIV-RNA levels and CD4 count and the use of HAART was analyzed and compared. RESULTS The total incidence of oral candidosis was 31.0% (486/1 566) and there was no difference in sex. The oral lesions were presented by three types, psudomembranous candidosis (PC), erythematous candidosis (EC) and angular cheilitis (AC), and the morbidity was 13.9% (217/1 566), 17.0% (267/1 566) and 4.9% (77/1 566), respectively. The average level of CD4 count in psudomembranous candidosis, erythematous candidosis and angular cheilitis [81.0 (146.0), 74.0 (152.0) and 69.0 (121.5) cell/µl] showed no significant difference (P > 0.05). The incidence of oral candidiasis in non-HAART and HAART subjects were 36.3% (402/1 107) and 18.3% (84/459), respectively (P = 0.000). The CD4 count and absolute counts of HIV viral load in oral candidiasis patients and non-oral candidiasis patients had significant difference (Z = -10.261, P = 0.000 and Z = -4.762, P = 0.000). CONCLUSIONS The morbidity of oral candidiasis in HIV/AIDS patients in Yunnan Province was high, including PC, EC and AC and hyperplastic candidosis was not detected. The incidence was related to the degree of immune suppression and HIV viral load.

Abstract
Impairments in taste perception may be caused by a number of factors, including the presence of Candida albicans in the oral cavity. We attempted to establish whether the presence of Candida albicans on the tongue is a cause of taste disorders by studying taste disorders in patients with candidosis of the tongue and in healthy "carriers" and "non-carriers" of C. albicans. Taste disorders and their severity were objectively assessed by the filter-paper disk method in 18 patients with candidosis of the tongue and in 33 healthy "carriers" and 167 healthy "non-carriers" of C. albicans. The gustatory function was re-tested in 7 patients and 8 "carriers" after treatment with topical anti-mycotic medication to detect any improvement. Patients with candidosis of the tongue and "carriers" of C. albicans demonstrated significantly higher incidences (p<0.001) of taste disorders than did "non-carriers". The mean taste threshold of each of the four individual taste qualities was significantly higher in patients with candidosis than in "non-carriers". The average taste threshold was significantly higher in "carriers" than in "non-carriers". Post-treatment improvement or recovery from taste disorders was obtained in 5 out of 7 patients (71.4%) with candidosis and in 7 out of 8 "carriers" (87.5%) of C. albicans. This study clearly demonstrates that not only overt candidosis of the tongue but also commensal harboring of C. albicans is a cause of taste disorders.

Abstract
PURPOSE To review 22 patients with globus pharyngis among a group of 39 patients who presented with burning mouth syndrome and to highlight the clinical presentation and treatment outcome of these oropharyngeal symptoms, often ignored by practicing oral surgeons. PATIENTS AND METHODS We carried out a retrospective review of 39 patients with burning mouth syndrome seen at oral surgery units of three specialist hospitals in Enugu, Nigeria between 2001 and 2010. The focus was on the 22 of these patients with burning mouth syndrome and globus pharyngis (the persistent sensation of having phlegm, a pill or some other sort of obstruction in the throat when there is none). Relevant information included patients' oral habits and dental status, past medical history, sociodemographic data, onset of symptoms and treatment outcome. RESULTS Amongst the 22 patients, 8 (36.4%) were males while 14 (63.6%) were females, giving a male to female ratio of 1:1.8. Of the 8 male patients, 3 (37.5%) were retrenched workers, 2 (25%) were drug addicts, 2 (25%) had a history of psychiatric problems and 1 (12.5%) had post-radiation therapy due to diagnosis of adenocystic carcinoma. Amongst the 14 female patients, 6 (42.8%) were divorcees, 3 (21.4%) were unemployed and unmarried, 2 (14.3%) had menopausal problems, 2 (14.3%) had dental prostheses and 1 (7.2%) had a history of mental disorder. CONCLUSION Globus pharyngis can present at the same time in some individuals with burning mouth syndrome. The emotional aetiological factor in this unusual ailment calls for proper examinations and a multidisciplinary approach in the management of patients who presented with burning mouth syndrome, especially with a history of depression.

Abstract
The purpose of this cross-sectional survey was to assess the knowledge and attitudes towards patients with HIV/AIDS among dental students in H.P. Government Dental College, Shimla, India. In November 2011, a survey was conducted of all the dental students of the college using a forty-five-item, self-administered questionnaire. The total mean knowledge score was 68.3 percent (good knowledge). The mean knowledge score was statistically higher in the clinical group than in the preclinical group. A majority of the students were aware of the association between HIV and oral candidiasis (89.1 percent), major aphthous (83.2 percent), and Kaposi's sarcoma (68.9 percent). Only 4.9 percent had professional attitudes about treating patients with HIV/AIDS. Male students had significantly fewer negative attitudes and higher positive attitudes than female students. The overall attitude score was significantly higher in the clinical group than in the preclinical group. Although a majority of the students had good knowledge, there were some inadequacies in their knowledge; those were more frequently seen in the preclinical students. It is important that dental students, as future dentists, develop not only the necessary practical skills but also knowledge and attitudes that will prepare them to treat patients with HIV/AIDS.

Abstract
With increasing numbers of people with HIV/AIDS receiving oral dental care, dentists should have sufficient knowledge of the disease, and their attitude should meet professional expectations. HIV and AIDS-related knowledge among dental students provides a crucial foundation for efforts aimed at developing appropriate education on these topics. Accordingly, the aim of this study was to assess the HIV/AIDS-related knowledge and attitudes amongst the 460 dental students of the Institute of Dental Sciences, Bareilly (UP), India. A self-administered survey consisting of fifty-three structured questions was conducted with the students. Overall, the response rate was 79.7 percent. The total mean knowledge and attitudes scores were 78.8 percent (excellent) and 77.7 percent (positive). There was no statistically significant difference between the knowledge and attitude scores of males and females. Regarding oral manifestations, Kaposi's sarcoma and candidiasis were the most identified. The results indicated that the students' knowledge on HIV/AIDS generally increased as they progressed through the curriculum, but their utilization of all barrier techniques for infection control and clinical protocol lacked consistency and compliance. Hence, there is a need to address, more clearly, the students' misconceptions and attitudes towards the disease.

Abstract
OBJECTIVES The objective of this study was to investigate oral Candida colonization and candidosis in a group of patients with psoriasis and controls. STUDY DESIGN A total of 100 patients with psoriasis and matched controls underwent the concentrated oral rinse test for Candida isolation. Candida species were identified by the VITEK 2 Identification System. Categorical variables were evaluated using the χ(2) test. The median Candida count was compared using the Mann-Whitney U test. RESULTS Oral candidiasis was diagnosed in 3% of the patients with psoriasis. The Candida count and prevalence were significantly higher in the patients with psoriasis compared with controls (69% vs 44%, P < .001), but with no relationship to the severity or treatment of psoriasis. Oral Candida was significantly higher in late-onset (at age ≥30 years) compared with early-onset psoriasis (at age <30 years). CONCLUSIONS Patients with psoriasis have increased oral Candida colonization and candidiasis. Further studies are needed to clarify the predisposing factor(s) for oral Candida in patients with psoriasis.

Abstract
There is a paucity of information about the factors associated with oral colonization with Candida species and the changes associated with antiretroviral (ARV) therapy. This study investigated the role of ARV therapy and other factors in a study population. Relevant clinical and laboratory information was obtained and oral rinse specimens were tested for yeast identification. The findings were compared with previous data from the same clinic before ARV therapy was available. Of 197 patients, 117 (59.4 %) were colonized. Candida albicans was the dominant species (71 %) and Candida dubliniensis was the most frequent non-albicans Candida. The colonized group had a higher rate of concurrent tuberculosis (TB) infection (77.4 % compared with 56 % in the non-colonized patients, P = 0.03) and a lower median CD4(+) count (346.5 cells mm(-3)) compared with the non-colonized group (418 cells mm(-3)). Participants not on ARV therapy and those having oral prosthesis were all colonized (P = 0.003 and P = 0.022, respectively). The oral Candida count was negatively correlated with the CD4(+) count in participants on ARV therapy (P = 0.006). Associated factors using logistic regression were dental caries (odds ratio = 1.30; 95 % confidence interval = 1.07-1.60] and diabetes mellitus (odds ratio = 5.52; 95 % confidence interval = 1.68-18.12). The colonization rate was higher (81.3 %) as well as the yeast count before ARV therapy was available, while the prevalence of C. dubliniensis was found to have increased from 6.3 to 11 %. Dental caries, diabetes mellitus, oral prostheses and TB infection were associated with oral colonization. The colonization rate, variety and yeast counts declined with ARV therapy.

Abstract
Mycotic stomatitis is one of the most frequent oral complications in cancer patients, but the effects of drug therapy for the disease are unknown. A prospective study was conducted to determine the effects of drug therapy for mycotic stomatitis in hospitalized patients, including cancer patients. ITCZ-OS and MCZ-GEL were used as antifungal agents. Atotal of 104 hospitalized patients were the study subjects for whom the Department of Dentistry was requested to provide dental treatment or oral care by other departments between March and May 20XX. Mycotic stomatitis was seen in 29%(n=30)of the subjects. Among subjects with mycotic stomatitis, 60%(n=18)had cancer, 57%(n=17)received steroids for two weeks or less, 57%(n=17)showed a performance status of 3 or 4, 70%(n=21)had mild to more severe xerostomia, and 53%(n=16)had an unclean oral cavity. As a result of drug therapy, the clinical symptom scores for white coat and flare and the total score were significantly improved on days 3 and 7 compared with before treatment, and the overall improvement rate was 83% on day 3 and 88% on day 7. Many patients hospitalized with mycotic stomatitis have cancer, and it was suggested that drug therapy is effective for them.

Abstract
BACKGROUND Oral microbial flora and a damaged oral mucosa may increase the risk of bacteriemia, fungemia and complications in immunocompromised patients. AIM OF THE STUDY Assessment of presence: bacteria and Candida spp. in different oral lesions, and the incidence of bacteremia in the case of a damaged mucosa in transplant recipients and patients receiving anti-tumour chemotherapy. MATERIAL AND METHOD Forty-five patients – 18 months to 18 years of life, were included (20 – organ recipients, 14– anti-tumour chemotherapy, 11 – control group). Clinical, oral mucosa examination focused on the type, severity and site of lesions, and microbiology assessed the presence of bacteria and fungi in the material from lesions. Blood cultures were performed in ten immunocompromised patients with manifestations of systemic infection. The control material consisted of blood cultures made prior to the onset of oral lesions and after 4–6 weeks following their remission in a diagnosed bacteremia. The statistical analysis was performed. RESULTS In the subjects with secondary immunodeficiency, among other coagulase-negative Staphylococcus (CoNS), Candidia spp. were more frequent. In cancer patients, mucositis was associated with Candida spp., Streptococcus spp. Organ recipients with stomatitis exhibited the presence of CoNS, Streptococcus viridians and other. Oral lesions in the control group contained Haemophilus parainfluenzae, Neisseria spp. and Staphylococcus aureus. In 30% of immunocompromised patients, oral lesions were accompanied by bacteremia. CONCLUSIONS A correlation has been found between oral lesions and the presence of S. aureus in patients without secondary immunodeficiency, and of CoNS, Enterococcus spp., Candida spp. in immunocompromised patients.

Abstract
Dysphagia following cardiac surgery is a frequently encountered problem, being most commonly due to the sternotomy incision and/or prolonged intubation. Oesophageal candidiasis is an increasing problem that is usually associated with immunosuppression or immunodeficiency. We report a 59 years age, immunocompetent lady whom had developed dysphagia and odynophagia following open cardiac surgery and long term course of antibiotics. Diagnosis of Candida oesophagitis was established after radiological, endoscopic and microbiological evidence, and successful treatment with combined topical and systemic antifungal therapy was achieved. Possibility of immunodeficiency was excluded. We believe that this lady developed oesophageal candidiasis due to a long-term course of broad spectrum antibiotics. We discuss the various diagnostic modalities and treatment options.

Abstract
OBJECTIVES Candida albicans is the most common fungal pathogen in humans, but other Candida species cause candidosis. Candida species display significant differences in their susceptibility to antimycotic drugs. Patients with symptomatic or erythematous oral lichen planus (OLP) commonly have Candida infection requiring correct identification of Candida species in order to initiate adequate antimycotic therapy. Therefore, conventional cytosmear and culture tests were compared with genetic diagnostics on oral rinse followed by agar culture and material collected by cytobrush from OLP patient mucosal lesion. METHODS The genetic approach was validated on a reference panel of 60 well-defined unrelated fungal species. The study included 37 OLP patients. Oral candidosis (OC) was established based on clinical signs of OC and/or oral mucosal symptoms and at least one hypha in lesional cytosmear. Antimycotic treatment was initiated after OC diagnosis, and symptomatic treatment was initiated in no-candidosis situations. RESULTS The composition of Candida species in oral rinse/culture test was different from that of lesional cytobrush sampling as more non-albicans species were detected by the latter. Unexpectedly, Candida dubliniensis was found to be overrepresented among patients with a history of antimycotic treatment indicating unintentional iatrogen selection. Of the 22 OLP patients receiving treatment, 27% of these should have been offered alternative therapy based on the improved diagnostic approach. CONCLUSION This study highlights the importance of lesional sampling in OLP patients with suspected OC. CLINICAL RELEVANCE Correct fungal identification is critical in order to initiate adequate antimycotic therapy, thus minimizing iatrogen selection of non-albicans species.

Abstract
OBJECTIVE The main objective of this study was to investigate the effect of brief exposure to subtherapeutic concentrations of chlorhexidine gluconate on germ tube formation of Candida albicans isolates obtained from smokers, diabetics, asthmatics using steroid inhalers and healthy individuals. MATERIALS AND METHODS Forty isolates of C. albicans were used in this study. All these isolates were quantified for germ tube formation without exposure to the drug and were used as the control group for data analysis. Isolates were also exposed to three subtherapeutic concentrations of chlorhexidine gluconate (0.00125, 0.0025 and 0.005%) for 30 min (limited exposure); the antiseptic was then removed and germ tube formation of these isolates was quantified microscopically following incubation in a germ tube-inducing medium. RESULTS Compared with the unexposed controls, brief exposure to all concentrations of chlorhexidine gluconate suppressed the ability of the C. albicans isolates to form germ tubes in increasing order by 13.72% (p < 0.001 to p = 0.02), 46.16% (p < 0.001) and 72.46% (p <0.001). CONCLUSIONS These findings show that brief exposure to subtherapeutic concentrations of chlorhexidine gluconate may modulate germ tube formation of C. albicans isolates, thereby suppressing their pathogenicity, and further elucidate the pharmacodynamic mechanisms by which chlorhexidine gluconate may operate in vivo.

Abstract
Investigations into the complex interaction between the fungal pathogen Candida albicans and its human host require the use of animals as in vivo models. A major advance is the creation of a low-oestrogen murine model of concurrent oral and vaginal C. albicans colonisation that resembles human candidal carriage at both mucosal sites. Weekly intramuscular (5 μg) and subcutaneous (5 μg) oestrogen administration was determined as optimal, enhancing oral colonisation but essential for vaginal colonisation. Using a clinical C. albicans oral isolate, persistent colonisation for up to 6 weeks can be achieved at both sites in two strains of mice (BALB/c and C57BL/6). This concurrent model of mucosal colonisation reduces the numbers of experimental mice by half, and opens up new avenues of research in assessing potential mucosal vaccine candidates and in studying delicate host-pathogen interactions during the most natural state of C. albicans epithelial colonisation.

Abstract
OBJECTIVE Our aim was to quantify prevalence, incidence, and recurrence of oral lesions (OL) among a population in the Southeast. METHODS A retrospective study based on chart review was conducted among patients (n = 744) who were ≥19 years of age and initiated highly active antiretroviral therapy (HAART) between January 2000 and June 2006 at the University of Alabama at Birmingham (UAB) 1917 Clinic. Patients' laboratory data and oral conditions were recorded for 2 years after enrollment into the study. RESULTS During 2 years of follow-up, the period prevalence of individuals experienced at least one OL was 35.6% (266/744). Among all of the 374 episodes of OL, 183 were new cases, while 57 were recurrences. The OL person-visit incidence rate was 0.02 per 100 person-visits. Oropharyngeal candidiasis (OPC) was the most frequent manifestation in terms of period prevalence (74.9%) with a person-visit incident rate of 0.01 per 100 person-visits. CONCLUSIONS Patients undergoing HAART continue to be affected by HIV-related oral conditions, especially OPC. These results clearly indicate that OL during HIV infection are still highly prevalent in spite of the improvements in medical care and the availability of HAART.

Abstract
Inflammatory papillary hyperplasia of the palate (IPHP) is a tissue-reactive overgrowth characterized by hyperemic mucosa with nodular or papillary appearance in the palate. The exact pathogenesis is still unclear. In this study, the presence of Candida albicans in the epithelial lining was evaluated using the indirect immunofluorescence staining technique. Strongly stained C albicans was observed only in the lesions of the IPHP group. Therefore, the detection of C albicans in almost all samples from IPHP tissue enabled a suggestion as to the microbial etiology of the disease, since the use of dental prostheses was reported.

Abstract
We report the case of a 16 years old female patient, with a pregnancy history of 11.4 weeks by ultrasound and intrauterine fetal death. In a private clinic were prescribed methotrexate 500 mg intramuscular single dose, and vaginal misoprostol. She had a clinical feature of five days of evolution characterized by fever of 39 degrees C, nausea, general attack and vomiting. The initial diagnosis was severe sepsis secondary to septic abortion, oral candidiasis and acute poisoning by methotrexate. After that, she was referred to the Instituto Nacional de Perinatologia, where stayed with fever for four days, and was managed with hydration, antibiotics, folinic acid and alkalizing. Her recovery was gradual. She was discharged after 12 days with significant clinical improvement. The literature review describes that the use of methotrexate for abortion purpose with therapeutic-dose presents a similar adverse effects to those found in our patient, however there are no case reports that describe the use of this drug in macrodosis for the same purpose, and their cytotoxic effects. We present this case because the patient used a macrodosis of this antimetabolite and due to the premature and empirical management with folinic acid, joined with alkalinization of urine, is the ideal treatment and as it is illustrated in our case.

Aicardi syndrome: a case report. EUROPEAN JOURNAL OF PAEDIATRIC DENTISTRY 2010; 11:146-148. [PMID: 21080756] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 05/30/2023]
Abstract
BACKGROUND Aicardi Syndrome is an X-linked autosomal recessive neurodegenerative encephalopathy. The diagnostic triad is composed by infantile spasms, agenesis of corpus callosum and chorioretinal lacunae. Additional common findings are: microencephaly, spasticity and severe mental delay. It affects only females because of early embryonic lethality in males. A significant number of females with Aicardi syndrome are of normal birth and develop normally until three months of age when infantile seizures begin. Psychomotor retardation is usually severe, neuromotor retardation is commonly present with lack of motor and language skills. Literature reports only few information about the dentofacial features of the syndrome. CASE REPORT We present the case of a patient, by describing the dental and facial characteristics with focus on dental prevention in order to avoid dental pain and the risks connected to general anaesthesia, and ultimately for improving the quality of life.

Abstract
Denture stomatitis is a primarily oral disease that affects denture wearers. The presence of Candida albicans in the palatal mucosa, on the internal surface of the maxillary denture, and in the blood of patients with denture stomatitis was evaluated. Although the results did not show C albicans in the bloodstream of patients, a strong relationship between denture stomatitis and Candida sp was confirmed for both the palatal mucosa and maxillary denture.

Abstract
BACKGROUND This study aimed to determine the prevalence of various oral and peri-oral manifestations in people living with HIV/AIDS in Tanzania. METHODS A cross sectional study. A total of 187 persons with HIV infection were recruited from non-governmental organisations serving people living with HIV/AIDS, 16.6% were males and females 83.4%. Information on weight and height, as well as extra oral and intra oral examinations for different manifestations were gathered. Treatment and referral for special care were offered. RESULTS At least one oral lesion was present in 45% of the participants. Candidiasis (28.9%) and non-tender lymphadenopathy (11.8%) were the most common lesions. Candidiasis occurred most frequently on lips/mucosa, and the tongue, and pseudomembranous candidiasis was the most frequent type. Candidiasis occurred with several other conditions and was statistically significantly associated with low body mass index (BMI). CONCLUSION This community survey carried out in an African sub-Saharan country showed that oral lesions are frequent among people living with HIV/AIDS. As emphasised by the World Health Organization Global Oral Health Programme, national HIV/AIDS programmes should incorporate oral health components.

Abstract
This study sought to compare techniques used to make a quantified evaluation of Candida spp. in children infected with HIV. Twenty-four HIV-infected children (age 3 to 13) were selected. Three sterilized swabs were used for each child: one for the dorsum of the tongue, one for the hard palate mucosa, and one for the right jugal mucosa; each swab was rubbed for 10 seconds and transferred to sterilized test tubes containing 1 mL of 0.9% saline solution. Candida spp. growth was observed in 95.8% of all samples, including 95.7% of tongue samples (Group T), 87.0% of saliva samples, 56.6% of hard palate mucosa samples (Group P), and 47.8% of right jugal mucosa samples (Group J). There was no statistical difference in Candida spp. growth between saliva samples and Group T samples, although both had higher growth compared to Groups P and J (p < 0.05; chi(2)). Regarding the sensitivity of each site for positive Candida spp. growth, Group T samples showed 69.5%, while saliva samples showed 52.2%, Group P samples showed 21.7%, and Group J samples showed 13.04%, with no significant statistical difference between Group T and saliva; however, both were more sensitive than Groups J and P (p < 0.05, chi(2)). It was concluded that whole stimulated saliva and swabbing the tongue were considered satisfactory for measuring Candida spp. in HIV-infected children.

Abstract
The increased incidence of invasive candidosis in numerous categories of patients, including neonates, cancer patients, AIDS patients and patients who have undergone organ transplantation, is of great concern for the physicians involved. The manifestations of candidosis are numerous, and various clinical entities such as localized and disseminated infection have to be considered separately. All types of localized candidosis per se are usually not the main cause of disseminated disease. However, spreading of the mycotic pathogens in the gastrointestinal tract could induce disseminated candidosis. Prophylactic measurements in risk patients and consequent local and, if necessary, systemic treatment is recommended in these clinical entities.
