Introduction Most fungal infections are responsive to antifungal therapy. However, failure to diagnose the same can significantly affect the quality of lives of patients. Timely identification of fungal infections and their association with varied demographic and clinical parameters will help in improving the prognosis of the patient. The present study aims to evaluate the prevalence of fungal infections among various age groups and genders and also to evaluate the association of fungal infections with demographic parameters. Methods This study included a sample size of n = 600. The demographic and clinical details were compiled and transferred to IBM SPSS Version 23 software (IBM Corp., Armonk, NY) for statistical analysis. Descriptive and Pearson chi-square tests were used to analyze the association of the type of fungal infection with gender, age, and comorbidities. A p-value of less than 0.05 is considered statistically significant. Results Angular cheilitis (40%, 240), followed by denture stomatitis (37.5%, 225), were the most common type of fungal infection among the sample population, and the elderly age group (51-72 years) was the most affected. Angular cheilitis was the most common infection among both males (21.4%, 128) and females (18.6%, 112), but candidiasis was reported more in females (18%, 108) than males (3%, 18) (p = 0.00). Angular cheilitis (32%, 192) and candidiasis (18%, 108) were more observed in association with anemia; however, denture stomatitis (34%, 204) was significantly higher among diabetics (p = 0.00). Conclusion The identification of associated systemic and demographic factors is as important as the treatment of fungal infection itself. The recognition of fungal infections and the role of parameters like age, gender, and systemic comorbidities in the development of fungal infections will have valuable implications for public health. Future research is required for a clear understanding of the same.

UNASSIGNED: Assessing the knowledge of clinical dental students regarding prevalent geriatric oral diseases is crucial in evaluating their clinical competency. This study focuses on analyzing dental students\' knowledge of angular cheilitis (AC) and xerostomia in elderly patients.
UNASSIGNED: In this analytical cross-sectional investigation, clinical dental students from Universitas Airlangga were involved. We employed simple random sampling to select a minimum of 76 students and gathered data, including demographic information and knowledge about AC and xerostomia, through an online questionnaire. Respondents were then categorized into three groups based on their knowledge level: poor, moderate, and good. We utilized coefficient contingency and odds ratio analysis to explore relationships and effects between demographic factors and knowledge levels.
UNASSIGNED: The study findings indicated that a significant majority of respondents demonstrated a high level of comprehension regarding AC (58.4%). Conversely, a notable proportion of respondents exhibited limited knowledge regarding xerostomia (66.3%). Furthermore, our correlation analysis, which aimed to identify potential associations between knowledge levels and intrinsic factors such as gender, clinical interest, and proximity to geriatric individuals, did not reveal any statistically significant relationships (P > 0.05).
UNASSIGNED: Within the population of clinical dental students, there is a commendable level of knowledge concerning AC in the geriatric demographic. However, a substantial segment of students lacks adequate understanding when it comes to xerostomia.

BACKGROUND: Angular cheilitis, an infection mainly caused by Candida yeasts, is featured by the appearance of inflammatory lesions at the bilateral corners of the mouth, particularly in patients with poor oral hygiene, ill-fitting dentures and old age. The first isolation of an atypical yeast, Cystobasidium calyptogenae, from oral samples of a patient presenting with angular cheilitis is discussed in this study.
METHODS: Angular cheilitis was diagnosed in a 60-year-old denture-wearing woman who presented with an irritation fibroma on her right lower buccal sulcus over the premolar region. Primary cultures of her oral swab and oral rinse samples grew a pure culture of an uncommon yeast strain resembling Rhodotorula sp. Sequence analysis of the yeast internal transcribed spacer (ITS) gene region and D1D2 domain showed highest similarity (99.6% and 100%, respectively) to C. calyptogenae CBS 9125 type strain. Following 2 weeks of treatment with miconazole/fusidic acid and mouthwash, the oral lesion showed improvement with less erythema. C. calyptogenae was not isolated from the patient\'s oral samples upon repeat sampling.
CONCLUSIONS: This is the first report on the isolation of C. calyptogenae from human oral samples. The ability of C. calyptogenae to grow at 37 °C and the fact that it was the only yeast species isolated from the patient\'s oral samples suggests its pathogenic potential and possible involvement in angular cheilitis. The ubiquitous nature of the Cystobasidium yeast is believed to increase the likelihood of opportunistic infections among immunocompromised individuals. As Cystobasidium is phenotypically indistinguishable from Rhodotorula, an emerging opportunistic pathogen, surveillance using molecular identification in clinical settings is essential in providing accurate diagnosis and treatment of uncommon yeast infections.

OBJECTIVE: The aim of this pilot study was to clarify the acceptability and clinical efficacy of an oxygen-enriched oil-based gel for treatment of angular cheilitis.
METHODS: A class IIb medical preparation, packaged in appropriate syringes, was tested. Patients were instructed how to use the gel for 10 days: finger rub application (3 times daily) on the dried lesion after meals, without eating, drinking, or speaking for at least 30 min thereafter. The Wilcoxon signed-rank test was used to assess whether there were any differences in the distributions of reported pain and lesion dimension. A microbiological examination was also performed with oral swabs; chi-squared test was used to compare the difference in the presence of microorganisms before and after treatment.
RESULTS: Thirty patients were treated. A significant improvement in reported outcome and a significant reduction in the initially measured largest dimension of the lesion were observed after use of the clinical protocol. Additionally, a significant reduction in the pathogen count was found.
CONCLUSIONS: Even if with limitations, data showed that this medical preparation facilitated prompt recovery from reported pain, without adverse reactions. Further work with a larger study population, and possibly a randomized control medication, will be needed.

BACKGROUND: Melkersson-Rosenthal syndrome is a rare disorder that is characterized, in its full form, by recurrent facial nerve palsy, fissured tongue, and orofacial edema. Most cases present as oligosymptomatic or monosymptomatic forms. Its etiology is still unknown and its course is chronic and it may be progressive.
METHODS: We present the case of a nine-year-old girl with recurrent episodes of peripheral facial nerve palsy. During the study, lip edema, benign migratory glossitis, and angular cheilitis were observed, which is why a clinical diagnosis of Melkersson-Rosenthal syndrome was made.
CONCLUSIONS: This syndrome must be considered in the differential diagnosis with the presence of acute peripheral facial nerve palsy and/or facial edema due to its behavior and progressive evolution.
Antecedentes: El síndrome de Melkersson-Rosenthal es una entidad poco frecuente caracterizada, en su forma completa, por parálisis facial recurrente, lengua fisurada y edema orofacial. La mayoría de los casos se presentan como formas oligosintomáticas y monosintomáticas. Su etiología es aún desconocida y tiene un curso crónico que puede ser progresivo. Caso clínico: Presentamos el caso de una niña de nueve años de edad con episodios recurrentes de parálisis facial periférica. Durante su estudio se observó edema labial, glositis migratoria benigna y queilitis angular, por lo que se formuló el diagnóstico clínico de síndrome de Melkersson-Rosenthal. Conclusión: Debemos considerar este síndrome dentro del diagnóstico diferencial ante la presencia de parálisis facial periférica recurrente o edema facial, debido a su comportamiento y evolución progresiva.

Crohn\'s disease (CD) is a chronic and granulomatous inflammatory disease of the entire gastrointestinal tract. The etiopathogenesis is not fully elucidated. The most common symptoms in the active phase of the disease include abdominal pain, prolonged diarrhea, fever, fatigue, malaise and weight loss. Oral manifestations of CD are classified into specific for CD with granulomatous changes and non-specific ones. This rare extraintestinal manifestation of CD in adults may precede gastrointestinal tract involvement, occur together or appear after years of its duration. Oral lesions can be initiated by malnourishment, poor absorption of nutrients or side-effect of medications.
UNASSIGNED: We describe a 28-year-old female with a 9-years CD history, who presented in the active disease with oral lesions. They were classified as non-specific ones, and included oral candidiasis, irregular erythematous patches on the cheek mucosa, exfoliative lip inflammation, and angular cheilitis. The patient was treated with azathioprine, and since the last exacerbation of symptoms, induction therapy with adalimumab, (anti-TNF-alpha), has been prescribed. Nystatin was applied to treat the oral lesions, based on the microbiological assessment of the Candida albicans susceptibility, and symptomatic treatment. After a two-week treatment the oral mucosa was healed and angular cheilitis showed marked improvement compared to the initial presentation.
CONCLUSIONS: The young female with active CD presented the nonspecific lesions in the oral cavity. The lesions coexisted with the active inflammatory process in the intestinal tract with characteristic clinical symptoms, and were associated with sideropenic anemia. The implementation of the local therapy, systemic CD treatment and supplementation of micronutrient deficiencies have led to a healing of the oral lesions. We emphasize a personalized approach to treatment and close cooperation between the dentist and the gastroenterologist.

Angular cheilitis (AC) is a clinical entity first described in the XIX century, characterized by erythema, rhagades, ulcerations, and crusting of one or both lip commissures and perilabial skin, responsible of an unpleasant and painful discomfort. Aim of this manuscript was to examine and evaluate the therapeutic options actually available for AC. Despite antifungals being the first-line treatment for most of clinicians, very limited scientific evidence supports their reliability, with just two RCTs published between the 70\'s and the 80\'s. Furthermore, alternative topical treatments, various techniques of occlusal vertical dimension restoration, B-vitamin supplementation, anti-drooling prosthetic device, and photodynamic therapy have been experimented and proposed, mostly in the form of case reports or case series on a small number of individuals. Our group found in 1% isoconazole nitrate (ISN) and 0.1% diflucortolone valerate (DFV) ointment the most consistent AC treatment, due to the broad spectrum of ISN against many species of dermatohpytes and bacteria, and the anti-inflammatory properties displayed by DFV. However, further and well-designed trials on larger samples of patients are needed to assess the differential profile of consistency of the treatments outlined in literature and claimed by the authors of this paper.

OBJECTIVE: Vitamin B12 deficiency in infants is uncommonly reported from developed countries and generally lacks dermatologic manifestations. On the contrary, infantile vitamin B12 deficiency is common in India and cutaneous manifestations are a constant feature, although often overshadowed by neurologic and hematological manifestations. The aim of this study was to describe the skin changes of vitamin B12 deficiency in infants.
METHODS: A retrospective chart review of vitamin B12 deficient infants for clinical and laboratory parameters was performed and data analyzed.
RESULTS: Forty-three infants, 30 boys and 13 girls, aged 4 to 27 months, with vitamin B12 deficiency were identified. Skin hyperpigmentation was present in 41 infants; it was localized to the dorsa of hands and feet in 26. Fifteen infants had generalized hyperpigmentation; 10 had a reticulate pattern, and 5 had a homogeneous pattern. Brown and sparse scalp hair were present in all. Glossitis was seen in 5 infants and cheilitis in 3. Of the 32 infants who underwent laboratory investigations, 28 had anemia and 21 macrocytosis. Serum vitamin B12 was measured in 30 infants; it was low in 19. Of the 11 with normal serum vitamin B12 , 9 had received vitamin B12 before referral but had macrocytosis and low maternal serum vitamin B12 . The infants were treated with vitamin B12 . Skin pigmentation and mucosal changes resolved completely by 3-4 weeks, but hair changes were slower to reverse.
CONCLUSIONS: Cutaneous findings are a common feature of vitamin B12 deficiency in Indian infants and resolve with treatment.

OBJECTIVE: To report conservative treatment based on the use of dermal fillers for a case of recurrent angular cheilitis.
METHODS: An 80-year-old patient with a history of recurrent angular cheilitis that was not resolved with a conventional approach sought treatment. Complete remission of the pathology was achieved with the injection of hyaluronic acid fillers.
CONCLUSIONS: This case illustrates the potential of nonsurgical facial aesthetics (NSFA) for treating this common pathology among elderly people. This case report shows that, aside from achieving aesthetic goals, NSFA approaches can also help treat some oral pathology.

Radiotherapy of head and neck tumours causes numerous complications in the oral cavity. The most frequent side effects are: mucositis, osteoradionecrosis, hypogeusia or dysgeusia, xerostomia, dental caries, dentinal hypersensitivity. It is recomended to prevent, reduce or relieve these complications in the oral cavity.
