Presence of Incipient Fungal Infection in Atypical Squamous Lesions of the Lip.

ABSTRACT: Epidermal barrier disruption caused by atypical squamous proliferations of the lip (SOL) creates an ideal environment for fungal growth. Histologic features of SOL include parakeratosis overlying partial- or full-thickness keratinocyte atypia with or without invasion of the dermis, dermal solar elastosis, and scattered inflammatory cells which are predominantly lymphocytes. Histologic features of SOL with fungal superinfections overlap those seen in primary fungal cheilitis with reactive atypia, creating a diagnostic challenge. One-hundred seventy SOL cases were examined for the presence of fungal elements, and the histological features associated with superinfection were identified. Cases diagnosed as actinic cheilitis with fungal superinfection were carefully examined to rule out the possibility of misdiagnosed primary fungal cheilitis with reactive atypia. Histopathological characteristics commonly present with fungal hyphae included intraepidermal or intradermal neutrophils, bacterial colonies, and erosion or ulceration. Medical record review of those patients treated conservatively with topical antifungals revealed persistent clinical neoplasm and histological evidence of residual SOL on repeat biopsy. Thus, when biopsies exhibit histological overlap between these 2 entities, clinicians should keep a high index of suspicion for underlying SOL and carefully follow these patients if conservative antifungal therapy is initially trialed.

Clinical features, cytology and bacterial culture results in dogs with and without cheilitis and comparison of three sampling techniques.

BACKGROUND: Cheilitis is a common presentation in dogs associated with a variety of skin diseases and often complicated by microbial infections. OBJECTIVES: To describe and compare clinical and cytological features and bacterial culture results from the lower lips of dogs with cheilitis (as compared to healthy controls), and to evaluate three cytology sampling techniques for their abilities to differentiate between the groups. ANIMALS: Fifty six dogs with cheilitis and 54 controls. METHODS: Anatomy and clinical signs of the lower lip were recorded. Cytology samples taken by tape strip, direct impression and swabs rolled over skin were scored semiquantitatively for microorganisms, inflammatory cells and keratinocytes. Cytology scores were correlated with semiquantitative bacterial culture scores. RESULTS: Pure breeds, frequency of lip folds and all cytology scores except keratinocytes were higher in dogs with cheilitis than in controls, but a substantial overlap was seen in all microorganisms between the groups. Hypersensitivity disorders were diagnosed in 40 of 56 dogs with cheilitis. The tape strip technique yielded the greatest differences between groups. Bacterial growth was reported in 100% of dogs with cheilitis and in 93% of the controls. Pathogens such as Staphylococcus pseudintermedius, Escherichia coli and Pseudomonas spp were found more frequently in dogs with cheilitis. Cytology and bacterial culture were poorly correlated. CONCLUSION: Cheilitis was associated with primary hypersensitivity disorders and the presence of a lip fold was a predisposing factor. Results of aerobic culture were similar to prior studies on pyoderma of other body sites, except for higher rates of Pseudomonas spp. isolation.

Candida infection in oral leukoplakia: an unperceived public health problem.

OBJECTIVES: The study aimed to determine the proportion, known risk factors and etiology for Candida infection in leukoplakia lesions among patients with oral leukoplakia attending the Oral and Maxillofacial Clinic at a Tertiary Care Hospital in Sri Lanka. MATERIALS AND METHODS: Eighty clinically suspected oral leukoplakia patients were included. Two oral swabs each, from leukoplakia patients: one swab from the lesion and the other one from the contralateral unaffected corresponding area (as a control) were collected. Direct microscopy and culture followed by colony count and phenotypic identification were performed to identify pathogenic Candida species. RESULTS: Candida infection was seen in 47% of patients with oral leukoplakia. Candida albicans (94.7%) was the most common Candida species followed by Candida tropicalis (5.3%). Majority of Candida-infected lesions were seen in the buccal mucosa region. Alteration of taste (p = 0.021), having other oral lesions (p = 0.008), angular cheilitis (p = 0.024) and periodontitis (p = 0.041) showed a significant association with Candida-associated leukoplakia. Increasing age showed a significant tendency for Candida infection (p = 0.020). Smoking (p = 0.026) and betel-quid chewing (p = 0.006) were also found to be significantly associated, although alcohol consumption alone did not show a significant association. Oral leukoplakia patients who had all three habits: alcohol consumption, smoking and betel-quid chewing had a significant association with Candida infection (p = 0.004). CONCLUSIONS: Patients who had a combination of risk factors: smoking, betel-quid chewing and alcohol consumption were seen to have a significant association with Candida infection. Further betel-quid chewing alone and smoking singly was also significantly associated with Candida infection in oral leukoplakia.

Methicillin-resistant Staphylococcus Aureus Lip Infection Mimicking Angioedema.

BACKGROUND: It is rare for angioedema to be misidentified by the experienced clinician or for it to mimic another disease process. As an Emergency Physician, it is important to recognize and treat angioedema immediately. Of equal importance is the recognition and initiation of treatment of facial cellulitis. A case report follows that illustrates methicillin-resistant Staphylococcus aureus (MRSA) lip infection mimicking angioedema. CASE REPORT: Here, we describe a case of a 21-year-old man who presented with a swollen lower lip, initially diagnosed as angioedema. Further investigation revealed the cause of his lip swelling was actually a MRSA abscess and surrounding cellulitis, an unusual presentation for lip infection, which we discuss below. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Misidentifying MRSA lip infection for angioedema, with a delay in proper treatment, could result in serious morbidity or mortality.

[Bacterial lip abscess in an immunocompetent patient]. / Absceso bacteriano labial en paciente inmunocompetente.

Lip abscesses are a potentially serious condition rarely reported in the medical literature. This disease requires prompt diagnosis and treatment with hospitalization, intravenous antibiotics, and urgent surgical drainage. Clinical knowledge of this condition is essential to guide the differential diagnosis and correctly adapt the etiological treatment. The presence of necrotic and cavitated lesions requires ruling out immunosupression or methicillin-resistant agent. We report a necrotic and cavitated bacterial lip abscess caused by methicillin-sensitive Staphylococcus aureus in an immunocompetent male.

Angular cheilitis, part 1: local etiologies.

Angular cheilitis (AC) is a common condition characterized by erythema, moist maceration, ulceration, and crusting at the corners of the mouth. This article focuses on the common local factors that act alone and in combination to produce AC. These factors are categorized as irritant, allergic, and infectious causes. Identifying the underlying etiology of AC is a critical step in developing an effective treatment plan for this condition.

Oral candidiasis and angular cheilitis.

Candidiasis, an often encountered oral disease, has been increasing in frequency. Most commonly caused by the overgrowth of Candida albicans, oral candidiasis can be divided into several categories including acute and chronic forms, and angular cheilitis. Risk factors for the development of oral candidiasis include immunosuppression, wearing of dentures, pharmacotherapeutics, smoking, infancy and old age, endocrine dysfunction, and decreased salivation. Oral candidiasis may be asymptomatic. More frequently, however, it is physically uncomfortable, and the patient may complain of burning mouth, dysgeusia, dysphagia, anorexia, and weight loss, leading to nutritional deficiency and impaired quality of life. A plethora of antifungal treatments are available. The overall prognosis of oral candidiasis is good, and rarely is the condition life threatening with invasive or recalcitrant disease.

[Baker Rosenbach erysipeloid appearing as a granulomatous cheilitis]. / Erysipéloïde de Baker-Rosenbach prenant l'aspect d'une chéilite granulomateuse.

BACKGROUND: Baker-Rosenbach's erysipeloid is a skin infection caused by Erysipelothrix rhusiopathiae. It occurs essentially in humans exposed to animals colonized with this germ such as swine. The typical skin lesion, an erythematous macule generally localized to inoculation site, frequently in the extremities, quickly resolves spontaneously. The lips are an atypical site of this infection. We describe a case of chronic granulomatosis cheilitis in a farmer caused by E. rhusiopathiae. CASE REPORT: A 40-year-old farmer, a wild-boar hunter and chronic smoker with no history of tuberculosis, injury or insect bites, presented at our dermatology unit with ulcerative macrocheilitis of the lower lip ongoing for 1 year. Its surface was purulent. A biopsy specimen showed non-caseating epithelioid granulomas. Laboratory and radiological screening for tuberculosis, sarcoidosis and Crohn's disease, and parasitological examination for Leishmaniasis proved negative. Bacteriological examination identified E. rhusiopathiae and labial Baker-Rosenbach's erysipeloid was diagnosed. The lesion healed after 15 days of treatment with parenteral penicillin G (12m IU/d), totally disappearing after 3 months. DISCUSSION: Swine erysipelas usually occurs in man as Baker-Rosenbach's erysipeloid. This localized form of infection with E. rhusiopathiae is the most frequent and the lesion typically observed is a violaceous plaque, less inflammatory with induration; spontaneous regression occurs after a mean 3 months. To our knowledge, this case is the first report of ulceration associated with macrocheilitis. Histologically, the granuloma directed our investigation towards the principal aetiologies of granulomatosis cheilitis, such as tuberculosis considering the epidemiological context, sarcoidosis or Crohn's disease. The diagnosis of erysipeloid was supported by epidemiological evidence (occupational exposure), isolation of the germ at the lesion and its regression on treatment with penicillin G. CONCLUSION: Diagnosis of E. rhusiopathiae infection was confirmed by bacteriology. However, the hypothesis concerning the pathogenesis of its chronic course in our patient remains a subject of discussion.

The Oral HIV/AIDS Research Alliance: updated case definitions of oral disease endpoints.

The Oral HIV/AIDS Research Alliance (OHARA) is part of the AIDS Clinical Trials Group (ACTG), the largest HIV clinical trials organization in the world. Its main objective is to investigate oral complications associated with HIV/AIDS as the epidemic is evolving, in particular, the effects of antiretrovirals on oral mucosal lesion development and associated fungal and viral pathogens. The OHARA infrastructure comprises: the Epidemiologic Research Unit (at the University of California San Francisco), the Medical Mycology Unit (at Case Western Reserve University) and the Virology/Specimen Banking Unit (at the University of North Carolina). The team includes dentists, physicians, virologists, mycologists, immunologists, epidemiologists and statisticians. Observational studies and clinical trials are being implemented at ACTG-affiliated sites in the US and resource-poor countries. Many studies have shared end-points, which include oral diseases known to be associated with HIV/AIDS measured by trained and calibrated ACTG study nurses. In preparation for future protocols, we have updated existing diagnostic criteria of the oral manifestations of HIV published in 1992 and 1993. The proposed case definitions are designed to be used in large-scale epidemiologic studies and clinical trials, in both US and resource-poor settings, where diagnoses may be made by non-dental healthcare providers. The objective of this article is to present updated case definitions for HIV-related oral diseases that will be used to measure standardized clinical end-points in OHARA studies, and that can be used by any investigator outside of OHARA/ACTG conducting clinical research that pertains to these end-points.

Queilite angular em pacientes idosos: aspectos clínicos, microbiológicos, fatores etiológicos e manejo terapêutico / Angular cheilitis in elderly pacients: clinical and microbiological aspects, etiological factors and therapeutic management

Introdução: A queilite angular é uma lesão multifatorial de caráter essencialmente fúngico, que acomete as comissuras labiais e clinicamente se manifesta através de um padrão característico. Em idosos, em decorrência da idade avançada, o surgimento e a persistência da queilite angular ocorre em virtude da perda de dimensão vertical, edentulismo, imunossupressão, aumento da dobra cutânea, próteses mal adaptadas e redução da qualidade de vida. Objetivo: Realizar um levantamento na literatura científica acerca dos aspectos clínicos, microbiológicos, fatores etiológicos e tratamento da queilite angular em pacientes idosos. Métodos: Foram consultadas as bases de dados PubMed, SciELO e LILACS, utilizando os descritores DeCS/MeSH em português e inglês: "idosos", "queilite", "lesão", "elderly", "cheilitis" e "lesion". Após o cruzamento com o operador booleano AND, foi realizada apuração e análise, com a inclusão de 21 trabalhos. Para aprofundar a fundamentação teórica, 13 novas referências foram adicionadas, totalizando 34 estudos. Resultados: Clinicamente, a queilite angular se manifesta através de fissuras, eritemas, crostas uni/bilaterais, acompanhada de dor e prurido. A presença dos microrganismos Candida albicans, Staphylococcus aureus e Streptococcus pyogenes são comuns e dificultam no manejo terapêutico desta condição. Dentre as variadas formas de tratamento, destacam-se a Terapia Fotodinâmica antimicrobiana, uso de ácido hialurônico, além de antimicrobianos locais, especialmente os antifúngicos. Considerações finais: Por apresentar aspecto multifatorial e envolver diferentes tipos de microrganismos, seu manejo terapêutico é multimodal. Portanto, para um tratamento adequado, faz-se necessário que o cirurgião-dentista identifique as características clínicas e microbiológicas, além dos fatores etiológicos envolvidos no desenvolvimento da queilite angular.

Introduction: Angular cheilitis is a multifactorial lesion of essentially fungal character, which affects the labial commissures and clinically manifests itself through a characteristic pattern. In the elderly due to advanced age, the onset and persistence of angular cheilitis occurs due to loss of vertical dimension, edentulism, immunosuppression, increased skinfold, poorly adapted prostheses and reduced quality of life. Objective: To conduct a survey in the scientific literature about the clinical and microbiological aspects, etiological factors and treatment of angular cheilitis in elderly patients. Materials and methods: The PubMed, SciELO and LILACS databases were consulted, using the DeCS/MeSH descriptors in Portuguese and English: "idosos", "queilite" and "lesão"; "elderly", "cheilitis" and "lesion". After crossing with the Boolean operator AND, a survey and analysis was performed, with the inclusion of 21 studies. To deepen the theoretical foundation, 13 new references were added, totaling 34 studies. Results: Clinically, angular cheilitis manifests itself through fissures, erythemas, unilateral or bilateral crusts, accompanied by pain and itching. The presence of the microorganisms Candida albicans, Staphylococcus aureus and Streptococcus pyogenes are common and hinder the therapeutic management of this condition. Among the various forms of treatment, we highlight the antimicrobial Photodynamic Therapy, use of hyaluronic acid, as well as local antimicrobials, especially antifungals. Final considerations: Because it presents a multifactorial aspect and involves different types of microorganisms, its therapeutic management is multimodal. Therefore, for an adequate treatment, it is necessary for the dentist to identify the clinical and microbiological characteristics, in addition to the etiological factors involved in the development of angular cheilitis.

Angular cheilitis: A clinical and microbial study.

AIMS: The aim of the present study was to examine clinical types and microbiological flora isolated from angular chelitis. MATERIALS AND METHODS: An eroded and/or erythematous, with or without fissure formation, nonvesicular lesion radiating from the angle of the mouth was considered to be angular chelitis. A sample of the present study comprised of 40 patients having unilateral or bilateral angular chelitis and 20 healthy individuals without any lip lesions. Clinical examination was done. In both test and control groups, the sample for microbial analysis was obtained from angle of the mouth. RESULTS: Clinically, four types of angular cheilitis lesions were found, Type I, II, III, and IV. The most common type of lesion found was Type I lesion. Microorganisms isolated from the lesion were Staphylococcus aureus, Candida or Streptococci in 33 (82.5%) cases either in pure culture or mixed culture. Among these 33 patients, S. aureus was found in 25 (75.5%) cases, Candida in 16 (48.4%) cases, and Streptococci in 5 (13.5%) cases, respectively. Out of 16 cases positive for Candida, in 13 cases further isolation of Candida was possible. Candida albicans was found in 6 cases and Candida stellastodia in 7 cases. In majority of the dentulous and edentulous patients, S. aureus showed profuse growth. CONCLUSIONS: There are microorganisms associated with angular cheilitis.

Managing complications of radiation therapy in head and neck cancer patients: Part VI. Management of opportunistic infections.

Head and neck cancer is becoming a more recognizable pathology to the general population and dentists. The modes of treatment include surgery and/or radiation therapy. Where possible, pretreatment dental assessment shall be provided for these patients before they undergo radiation therapy. There are occasions, however, whereby head and neck cancer patients are not prepared optimally for radiation therapy. Because of this, they succumb to complicated oral adverse effects after radiation therapy. The last part of this series reviews the opportunistic infections that can occur to the perioral structure. Their management is briefly discussed.

[Tuberculous cheilitis revealing pulmonary tuberculosis]. / Chéilite tuberculeuse révélant une tuberculose pulmonaire.

Tuberculosis of the oral cavity is rare. It is associated with clinical polymorphism and poses above all a diagnostic problem. We report the case of a 42-year-old male patient with tubercular cheilitis. This study aims to focus attention on tuberculosis that can be detected exceptionally in specific locations, such as the oral lip.

Oral candidiasis.

Oral candidiasis (OC) is a common fungal disease encountered in dermatology, most commonly caused by an overgrowth of Candida albicans in the mouth. Although thrush is a well-recognized presentation of OC, it behooves clinicians to be aware of the many other presentations of this disease and how to accurately diagnose and manage these cases. The clinical presentations of OC can be broadly classified as white or erythematous candidiasis, with various subtypes in each category. The treatments include appropriate oral hygiene, topical agents, and systemic medications. This review focuses on the various clinical presentations of OC and treatment options.

Multiple suppurative cystic lesions of the lips and buccal mucosa: a case of suppurative stomatitis glandularis.

Cheilitis glandularis (CG) is a rare inflammatory salivary gland disease that usually affects the lips. Although the etiology of CG is still unknown, it is believed to be a hereditary disease with an autosomal dominant pattern of inheritance. Three clinical presentations of CG are described in the literature: simple, superficial suppurative, and deep suppurative. A case of deep suppurative CG that extended to the buccal mucosa has been previously reported as suppurative stomatitis glandularis (SSG). Here we report a case of SSG in a 64-year-old white female with a history of bilateral renal transplants for adult polycystic kidney disease, who presented with painful swollen lips and bilateral buccal mucosal lesions. The diagnosis and management of the case is discussed. To the best of our knowledge, this is the second report of SSG, a rare condition affecting the minor salivary glands in the oral cavity.

In-vitro proteinase production by oral Candida albicans isolates from individuals with and without HIV infection and its attenuation by antimycotic agents.

In-vitro proteinase production by oral Candida albicans isolates from patients with and without HIV infection (18 isolates from each group) was assessed by image analysis of a plate assay, with bovine serum albumin (BSA) as a substrate. The effect of sub-minimal inhibitory concentrations (sub-MICs) of nystatin, amphotericin B, clotrimazole and miconazole on in-vitro proteinase production by these yeast isolates was also investigated. Proteinase production by C. albicans isolates from patients with HIV infection was significantly greater than production by those from individuals without infection. All 18 isolates from HIV-infected individuals produced proteinase, in comparison to 56% of isolates from uninfected individuals. Pre-exposure of C. albicans isolates (seven proteinase producers from each group) to 1/4 and 1/16 MICs of nystatin, amphotericin B, clotrimazole and miconazole resulted in decreased proteinase production in all isolates tested. However, after exposure to the four antimycotic agents, proteinase production was decreased to a significantly greater extent in isolates from uninfected individuals than in those with HIV disease. Furthermore, when the relative concentration effect of antimycotic agents on proteinase production was compared, C. albicans isolates from the HIV-free group demonstrated a salient dose-response relationship compared with the HIV-infected group. These results indicate that C. albicans from patients with HIV infection are significantly more proteolytic than those from individuals without the infection, and that polyenes and imidazoles curtail the proteolytic activity of all C. albicans isolates, albeit to a lesser extent in those from HIV-infected patients. It appears that HIV disease favours oral colonisation by more proteolytic C. albicans isolates, with resilient proteolytic activity.

Antibiotic sensitivity and phage typing of Staphylococcus aureus isolated from non-hospitalized patients with angular cheilitis.

Strains of Staphylococcus aureus were isolated from 360 patients with angular cheilitis. Of these 24 per cent were sensitive to penicillin G, 74 per cent to tetracycline, 93 per cent to fusidic acid and 96 per cent to erythromycin. Twenty per cent belonged to bacteriophage Group I, 9 per cent to Group II, 13 per cent to Group III, 39 percent miscellaneous and 19 per cent were untypable. A number of phage typing patterns which have been reported for strains associated with specific forms of staphylococcal disease were present in the 360 isolates. In investigations involving cross infection of Staph. aureus, both patients and staff should be examined for evidence of infection at the angles of the mouth.
