Co-occurrence of oral pemphigus vulgaris and herpes simplex virus infection in a young patient with Crohn's disease: report of a rare case of oral lesions during anti-TFN alpha and immunomodulator therapy.

BACKGROUND: Pemphigus vulgaris (PV) is a potentially life-threatening mucocutaneous autoimmune disease that affects desmoglein-1 and desmoglein-3, leading to intraepithelial vesiculobullous lesions. In the oral mucosa, PV lesions can mimic other diseases such as mucous membrane pemphigoid, other forms of pemphigus, recurrent aphthous stomatitis, erythema multiforme, Stevens-Johnson syndrome, and virus-induced ulcers like herpes simplex virus (HSV), making diagnosis challenging. The co-occurrence of PV with Crohn's disease is rare and predominantly seen in younger patients. The therapeutic mainstay for both PV and Crohn's disease usually involves systemic corticosteroids combined with immunosuppressants and immunobiological drugs. Literature indicates that the use of these drugs, particularly TNF-alpha inhibitors, for managing autoimmune diseases like Crohn's can potentially induce other autoimmune diseases known as autoimmune-like syndromes, which include episodes of lupus-like syndrome and inflammatory neuropathies. There are few cases in the literature reporting the development of PV in individuals with CD undergoing infliximab therapy. CASE REPORT: A young female with severe Crohn's disease, treated with the TNF-alpha inhibitor infliximab, developed friable pseudomembranous oral ulcerations. Histopathological and immunofluorescence analyses confirmed these as PV. The treatment included clobetasol propionate and low-level photobiomodulation, which resulted in partial improvement. The patient later experienced severe intestinal bleeding, requiring intravenous hydrocortisone therapy, which improved both her systemic condition and oral lesions. Weeks later, new ulcerations caused by herpes virus and candidiasis were identified, leading to treatment with oral acyclovir, a 21-day regimen of oral nystatin rinse, and photodynamic therapy, ultimately healing the oral infections. To manage her condition, the gastroenterologists included methotrexate (25 mg) in her regimen to reduce the immunogenicity of infliximab and minimize corticosteroid use, as the patient was in remission for Crohn's disease, and the oral PV lesions were under control. CONCLUSION: Young patients with Crohn's disease should be referred to an oral medicine specialist for comorbidity investigation, as oral PV and opportunistic infections can arise during immunosuppressive therapy. The use of TNF-alpha inhibitors in patients treated for inflammatory bowel disease, such as Crohn's, should be carefully evaluated for potential side effects, including oral PV.

Association between oral lesions and disease activity in lupus erythematosus.

BACKGROUND: Mucosal involvement is frequently seen in cutaneous lupus erythematosus (CLE) and systemic lupus erythematosus (SLE). There is no consensus regarding the prevalence, and a wide range of lesions has been reported. Its prognostic significance is currently unknown and a matter of controversy. OBJECTIVE: To classify oral lesions in lupus, evaluate their prevalence and assess their possible association with disease activity. METHODS: We conducted a descriptive study between 2016 and 2017. A total of 150 lupus patients were matched by sex, age and smoking status with 151 healthy individuals. All subjects underwent a careful evaluation of oral mucosa. On the same day of the clinical assessment, each patient underwent a peripheral venous blood and urine analysis. All patients underwent a full medical history, physical examination and a careful examination of the oral cavity. For each one, we obtained photographs of ten areas of the oral cavity. Two dermatologists of our group blindly recorded the presence and morphology of oral lesions. The disease activity of CLE patients was scored using the Revised Cutaneous Lupus Erythematosus Disease Area and Severity Index, and in SLE patients, activity was measured using the Systemic Lupus Erythematosus Disease Activity Index. RESULTS: In CLE patients, there was a statistically significant correlation between higher cutaneous disease activity and the following oral findings: discoid plaques, cobblestone and red/brown-pigmented macules. In patients with CLE, red macules on jugal mucosa were statistically associated with anaemia and positive antinuclear antibodies titres; additionally, the presence of gingivitis was related to systemic inflammation. In SLE patients, gingival telangiectases were statistically significantly associated with leucopenia, hypocomplementemia and systemic inflammation. LIMITATIONS: Biopsies on mucosal lesions were not performed. CONCLUSION: Some specific oral lesions correlate with disease activity in CLE and SLE.

Cárie de radiação: efeitos da radioterapia na estrutura dentária / Caries de radiación: efectos de la radiación en la estructura dental / Radiation caries: effects of radiotherapy on dental structure

Introdução: Pacientes submetidos à radioterapia para tratamento de neoplasias malignas na região de cabeça e pescoço são propensos a desenvolver complicações orais como a cárie de radiação, que evolui rapidamente e é altamente destrutiva.É reconhecido que o seu desenvolvimento está associado a alterações pós-radioterápicas nas glândulas salivares maiores, o que resulta em hipossalivação e alteração nos constituintes salivares. No entanto, tem sido aceito que danos diretos causados pela radiação à estrutura dentária podem acelerar a progressão da cárie e estudos têm demonstrado alterações morfológicas e físicas em dentes humanos após radioterapia. Objetivo: Propõe-se apresentar um caso de cárie de radiação e os efeitos diretos da radioterapia na estrutura dentária. Relato de caso: Paciente masculino, 60 anos de idade, com queixa principal de fragilidade dentária; relatou história de carcinoma epidermóide em língua há 18 meses e que o protocolo de tratamento aplicado foi quimioterapia (38 sessões), radioterapia (38 sessões) e cirurgia. Ao exame físico, dentre as alterações observadas, destacou-se a presença de regiões cervicais dentárias enegrecidas com coroas bastante fragilizadas em todos os dentes remanescentes, características de cárie de radiação. Foi realizado um tratamento atraumático, que está em acompanhamento. Conclusões: A cárie de radiação tem como principal fator etiológico alterações salivares qualitativas e quantitativas. A discussão sobre os efeitos diretos da radioterapia sobre a estrutura dentária ainda é bastante polêmica na literatura odontológica. Desta forma, sugere-se que mais estudos sejam realizados de forma sistemática, de maneira mais completa e padronizada(AU)

Introducción: Los pacientes sometidos a radioterapia para el tratamiento de tumores malignos en la cabeza y el cuello son propensos a desarrollar complicaciones bucales, tales como caries de radiación que evoluciona rápidamente y es altamente destructiva. Se reconoce que el desarrollo se asocia con cambios posradioterapia en las glándulas salivales, que resulta en hiposalivación y el cambio en los componentes salivales. Sin embargo, se ha aceptado que los daños por radiación directa a la estructura dental puede acelerar la progresión de la caries y los estudios han demostrado cambios morfológicos y físicos en los dientes humanos después de la radioterapia. Objetivo: presentar un caso de caries de radiación y los efectos directos de la radiación en la estructura dental. Presentación del caso: Paciente masculino de 60 años de edad, se quejaba de fragilidad dental, con historia notificada de carcinoma de células escamosas en la lengua hace 18 meses y con protocolo de tratamiento aplicado de quimioterapia (38 sesiones), terapia de radiación (38 sesiones) y cirugía. En el examen físico, de los cambios observados, se destacó la presencia de regiones cervicales dentarias negruzcas con coronas bastante frágiles en todos los dientes restantes, características de caries de radiación. El tratamiento atraumático se realizó y el paciente está bajo observación. Conclusiones: los cambios cuantitativos y cualitativos salivales actúa como el factor causal principal de la caries por radiación. La discusión acerca de los efectos directos de la radiación sobre la estructura del diente es todavía muy controvertido en la literatura dental. Por lo tanto, se sugiere que se realicen estudios adicionales de manera sistemática, más completa y estandarizada(AU)

Introduction: Patients undergoing radiotherapy as treatment for malignant head and neck tumors are prone to develop oral complications such as radiation caries, which evolves rapidly and is highly destructive. Such development is known to be caused by post-radiotherapy alterations in salivary glands resulting in hyposalivation and changes in salivary components. However, it has been accepted that damage by direct radiation to the dental structure may hasten the progress of caries development, and studies have shown the morphological and physical changes occurring in human teeth after radiotherapy. Objective: Present a case of radiation caries and the direct effects of radiation on dental structure. Case presentation: A 60-year-old male patient complains of dental fragility. The patient was diagnosed with squamous-cell carcinoma of the tongue 18 months ago and indicated chemotherapy (38 sessions), radiotherapy (38 sessions) and surgery. Physical examination revealed among other changes the presence of blackish cervical areas with quite fragile crowns in all remaining teeth, which are characteristic of radiation caries. Non-traumatic treatment was performed and the patient is now under observation. Conclusions: Salivary quantitative and qualitative changes are the main cause of radiation caries. Discussion about the direct effects of radiation on dental structure is still quite controversial in the literature on the topic. It is therefore suggested to conduct further studies in a more systematic, complete and standardized manner(AU)

Incidental finding of subgemmal neurogenous plaque upon retrospective evaluation of oral lymphoepithelial cysts.

PURPOSE: We aimed to compare the histomorphological features of oral lymphoepithelial cysts (OLC) in different locations of the oral cavity and to verify the association between oral lymphoepithelial cysts and subgemmal neurogenous plaque (SNP) on biopsies from the lateral border of the tongue. METHODS: All cases diagnosed as OLC from the Oral Pathology Service at the School of Dentistry/University of São Paulo were retrieved. For all the cysts located in the tongue, their association to SNP was analyzed. Immunohistochemical staining against S100 was performed to confirm the diagnosis of SNP. RESULTS: Thirty-one cases were selected for morphological analysis and SNP was identified in 40% of cases, all of them positive for S100. In these cases, macroscopic analysis demonstrated two independent fragments. Microscopic analysis showed that cysts located in the floor of the mouth and ventral surface of the tongue showed less intense exocytosis, less formation of lymphoid follicles, and predominantly a moderate inflammatory infiltrate. CONCLUSIONS: OLC have a similar histological pattern regardless the location within the oral cavity and. In some cases, the biopsy specimen may be accompanied by a SNP as an adjacent independent structure.

Oral Myiasis in a Patient With HIV Manifestations and Neurologic Toxoplasmosis Treated by Ivermectin.

Myiasis has been defined as a pathologic condition where dipterous larvae are lodged in mammalian hosts causing an infestation, which feeds on living or dead tissue for at least a certain period inside the host and develops itself as parasites. In humans, the most commonly affected sites are the nose, eyes, skin wounds, sinuses, lungs, ears, gut, gall bladder, vagina, nasal cavities, and rarely the mouth because the oral tissues are rarely exposed to the external environment. The etiology of oral myiasis is usually related to local factors such as poor oral hygiene, periodontal disease and labial incompetence, and systemic factors such as neurologic deficits.

Unusual Intestinal Involvement by Paracoccidioidomycosis Diagnosed After Oral Manifestation.

Paracoccidioidomycosis is a common deep fungus infection in South America, particularly in Brazil. It is acquired through inhalation and primary involvement of lungs. Subsequently, dissemination may occur and oral mucosa is frequently affected and actually, in most of the cases the diagnosis is established because of the oral lesions. Thus, the role of the dentist is fundamental to correct diagnosis. However, the involvement of intestine is rarely reported. The current case describes a 36-year-old man who presented abdominal pain and intestinal constipation, being suspected and then confirmed as paracoccidioidomycosis after already be diagnosed with this disease by a dentist through oral manifestations.

Condições bucais e metabólitos salivares de pacientes com mucopolissacaridose / Oral conditions and salivary metabolites of patients with mucopolysaccharidosis

Mucopolissacaridose (MPS) é uma doença genética hereditária causada pela deficiência de enzimas lisossômicas que afetam o catabolismo de glicosaminoglicanos, acarretando seu acúmulo em diferentes órgãos e tecidos causando alterações sistêmicas e bucais. O objetivo do estudo foi avaliar e descrever as manifestações bucais e caracterizar os metabólitos salivares de pacientes com MPS e através de relatos de caso investigar as manifestações presentes em pacientes com MPS-II com diferentes tempos de diagnóstico e tratamento. Foram selecionados pacientes de dois Centros de Referência em MPS no Rio de Janeiro (Instituto de Puericultura e Pediatria Martagão Gesteira e Instituto Fernandes Figueira) os quais foram atendidos na Faculdade de Odontologia ­ UFRJ. Treze pacientes portadores de MPS dos tipos I, II, IV e VI foram avaliados quanto às manifestações bucais (tecidos moles, relação oclusal, exame periodontal e dental). Amostras salivares foram coletadas de um paciente de cada tipo de MPS e de um paciente saudável para caracterização dos metabólitos salivares usando espectroscopia de Ressonância Magnética Nuclear. Os dados foram analisados descritivamente (SPSS 23.0) e empregados os testes Fisher e Kruskal-Wallis (p<0,05). A amostra foi composta por 3 pacientes MPS-I, 5 MPS-II, 1 MPS IV e 4 MPS-VI, 4 do sexo feminino e 9 masculino, com idades variando de 2-38 anos. A média de ceo-d/CPO-D variou entre 0-5 e a macroglossia foi a manifestação mais prevalente (61,5%) especialmente no tipo II (p=0,019). O índice de sangramento gengival variou entre os tipos de MPS (p=0,038), maior em pacientes do tipo II. O transpasse horizontal acentuado foi mais prevalente no tipo IV (p=0,005). Foram observadas diferenças nos metabólitos salivares entre os tipos de MPS em relação ao paciente saudável. As manifestações bucais e craniofaciais de pacientes com MPS tipo II com diferentes tempos de diagnóstico e tratamentos foram descritas em dois relatos de casos. Um paciente, gênero masculino, 7 anos de idade com diagnóstico intrauterino recebeu transplante de células-tronco hematopoiéticas aos 70 dias de vida. As principais manifestações bucais e radiográficas foram: macroglossia, mordida cruzada posterior, apinhamento, atraso na erupção, retenção de dentes decíduos, hipoplasia de esmalte, dentes posteriores com raízes curtas e alongamento dos processos estiloides bilateralmente. No segundo relato de caso dois pacientes portadores de MPS-II com diagnóstico tardio apresentaram manifestações craniofaciais e bucais acentuadas, reveladas através do exame tomográfico e avaliação da simetria através da sobreposição de imagens em 3D. Foram observados nesses pacientes: mordida aberta total, arcos dentários expandidos, severa hipoplasia condilar, processos coronoides aumentados além de macroglossia e maloclusão do tipo classe III. Pode-se concluir que a macroglossia e o transpasse horizontal acentuado foram associados respectivamente aos tipos de MPS II e VI. Há evidências da importância do diagnóstico/tratamento precoce na redução das manifestações craniofaciais em paciente com MPS-II. Diferenças nos metabólitos salivares de baixo peso molecular entre paciente saudável e portadores de MPS podem ser promissoras no entendimento da doença. (AU)

Mucopolysaccharidosis (MPS) is a hereditary genetic disease caused by the deficiency of lysosomal enzymes that affect the catabolism of glycosaminoglycans, causing their accumulation in different organs and tissues causing systemic and oral alterations. The objective of the study was to evaluate and describe oral manifestations and to characterize the salivary metabolites of patients with MPS and through case reports we also investigate the manifestations present in patients with MPS-II with different moments of diagnosis and treatment. Patients were selected from two MPS Reference Centers in Rio de Janeiro (Instituto de Puericultura e Pediatria Martagão Gesteira and Instituto Fernandes Figueira), which were attended at the Faculty of Dentistry - UFRJ. Thirteen patients with MPS types I, II, IV and VI were described of oral manifestations (soft tissue, occlusal relationship, periodontal and dental examination). Salivary samples were collected from one patient of each type of MPS as well as healthy ones to characterize the salivary metabolites using Nuclear Magnetic Resonance Spectroscopy. The data were analyzed descriptively (SPSS 23.0) and the Fisher and Kruskal-Wallis tests were used (p <0.05). The sample consisted of 3 MPS-I, 5 MPS-II, 1 MPS IV and 4 MPS-VI, 4 females and 9 males, with ages varying from 2-38 years. Mean of dmft / DMFT varied between 0-5 and macroglossia was the most prevalent manifestation (61.5%), especially type II (p = 0.019). The gingival bleeding index varied among MPS types (p = 0.038), higher in type II patients. The accentuated horizontal transpiration was more prevalent in type IV (p = 0.005). Differences were observed in salivary metabolites between MPS types in relation to the healthy patient. The oral and craniofacial manifestations of patients with MPS type II with different moments of diagnosis and in addition the treatment were described in two case reports. A 7-year-old male patient with intrauterine diagnosis received hematopoietic stem cell transplantation at 70 days of age. The main oral and radiographic manifestations were: macroglossia, posterior crossbite, crowding, delayed eruption, retention of deciduous teeth, enamel hypoplasia, posterior teeth with short roots and stretching of styloid processes bilaterally. In the second case report, two patients with MPS-II with late diagnosis showed marked craniofacial and buccal manifestations revealed by tomographic examination and evaluation of symmetry through the overlapping of 3D images. These patients were: total open bite, expanded dental arches, severe condylar hypoplasia, increased coronoid processes in addition to macroglossia and class III malocclusion. We concluded that the macroglossia and the accentuated horizontal transpiration were associated respectively with the MPS II and VI types. The importance of early diagnosis / treatment in the reduction of craniofacial manifestations in patients with MPS-II has been demonstrated. Differences in low molecular weight salivary metabolites between healthy and MPS patients may be promising on understanding this disease. (AU)

Alteraciones bucales asociadas a Diabetes mellitus tipo 1 en niños y adolescentes. Instituto de Endocrinología. Cuba. 2014-2015 / Buccal alterations associated to Type 1 Diabetes Mellitus in children and adolescents. Institute of Endocrinology. Cuba. 2014-2015

Introducción: La Diabetes Mellitus tipo 1 es una enfermedad sistémica crónica con repercusión a nivel bucal. Elevadas concentraciones de glucosa sanguínea de manera sostenida generan disminución del flujo salival, disminución de la respuesta vascular periférica lo que contribuye a la acumulación de placa bacteriana y tártaro, al desarrollo de caries, halitosis y enfermedad periodontal. Objetivo: Determinar la asociación de las alteraciones bucales y la Diabetes Mellitus tipo 1 en niños y adolescentes. Material y Métodos: Se realizó un estudio observacional de casos y controles, con un grupo de niños y adolescentes con Diabetes Mellitus tipo 1 (Grupo 1), de edades comprendidas entre 3 a 18 años y un grupo de niños y adolescentes sin Diabetes Mellitus (Grupo 2) de edades y sexo comparables. Resultados: Los pacientes con diabetes resultaron más afectados por xerostomía (37.8 por ciento), úlceras (55.6 por ciento) y periodontopatías (71.1 por ciento) que los pacientes sin diabetes, siendo estos resultados muy significativos estadísticamente, a diferencia de la afectación por caries dental y el comportamiento de la higiene bucal donde las diferencias no fueron estadísticamente significativas. Conclusiones: La Diabetes Mellitus tipo 1 se relaciona con las alteraciones bucales, así los niños y adolescentes diabéticos presentan mayor frecuencia de periodontopatías, xerostomía y úlceras que los niños y adolescentes sin diabetes, no sucede así con la caries dental ni la higiene bucal(AU)

Introduction: Type 1 Diabetes Mellitus is a chronic systemic disease with a repercussion upon a buccal level. High concentrations of maintained blood glucose generate a decrease of both the salivary flow and the peripheral vascular response, which contributes to the accumulation of bacterial plaque and tartar, the growth of cavities, halitosis, and periodontal diseases. Objective: To determine the association between buccal alterations and Type 1 Diabetes Mellitus in children and adolescents. Material and Methods: A case-control observational study was done in a group of children and adolescents with Type 1 Diabetes Mellitus (Group 1), from ages 3 to 18, and in a group of children and adolescents without Diabetes Mellitus (Group 2), of compared ages and sexes. Results: The patients with diabetes were more affected by xerostomia (37.8 percent), ulcers (55.6 percent), and periodontopathies (71.1 percent) than the patients without diabetes, being these results very significant statistically, unlike the affectation by dental cavities and the behavior of buccal hygiene where the differences were not statistically significant. Conclusions: Type 1 Diabetes Mellitus is related to buccal alterations; this way, diabetic children and adolescents present more frequent periodontopathies, xerostomies and ulcers than children and adolescents without diabetes, but it does not happen with dental cavities or buccal hygiene(AU)

Oral problems and quality of life of preschool children: self-reports of children and perception of parents/caregivers.

The purpose of this study was to evaluate the association between oral health problems and oral health-related quality of life (OHRQoL) of preschool children according to both self-reports and the reports of parents/caregivers. A school-based, cross-sectional study was conducted with 769 preschool children and their parents/caregivers. The OHRQoL was evaluated using the Scale of Oral Health Outcomes for Five-Year-Old Children (SOHO-5). Based on logistic regression for complex samples, the following variables were found to be associated with poorer OHRQoL in the parent/caregiver version: toothache (OR = 6.77; 95% CI: 3.95-11.59); consequences of untreated dental caries (OR = 2.69; 95% CI: 1.27-5.70); and anterior open bite (OR = 2.01; 95% CI: 1.13-3.56). The following variables were associated with poorer OHRQoL in the child self-report version: toothache (OR = 3.34; 95% CI: 2.11-5.29); cavitated lesions (anterior teeth) (OR = 2.20; 95% CI: 1.26-3.84); occurrence of traumatic dental injury (OR = 1.77; 95% CI: 1.19-2.61); and anterior open bite (OR = 1.95; 95% CI: 1.16-3.29). We conclude that children with dental caries (or its sequelae) had poorer OHRQoL. Having experienced a traumatic dental injury and having a malocclusion were also associated with a poorer OHRQoL.

The affected patients who did not receive opportune health care suffered complications (AU).

Oral Nodular Lesions in Patients with Sjögren's Syndrome: Unusual Oral Implications of a Systemic Disorder.

Sjögren's syndrome (SS) is a systemic chronic autoimmune disorder affecting the lacrimal and salivary glands. SS may manifest as primary SS (pSS) or secondary SS (sSS), the latter occurring in the context of another autoimmune disorder. In both cases, the dry eyes and mouth affect the patient's quality of life. Late complications may include blindness, dental tissue destruction, oral candidiasis and lymphoma. This paper reports two cases of SS, each of them presenting unusual oral nodular lesion diagnosed as relapsed MALT lymphoma and mucocele. The importance of the diagnosis, treatment and management of the oral lesions by a dentist during the care of SS patients is emphasized, as the oral manifestations of SS may compromise the patient's quality of life.

[Laugier-Hunziker syndrome in a patient with Sjögren’s syndrome: Report of one case]. / Posible asociación autoinmune entre síndrome de Laugier-Hunziker y síndrome de Sjögren: reporte de un caso y revisión de la literatura.

Laugier-Hunziker syndrome is a rare benign idiopathic condition characterized by acquired macular pigmentation of lips and buccal mucosa, often accompanied with melanonychia. The main concern with this condition is to rule out other differential diagnosis with systemic repercussions and similar hyperpigmentation patterns, such as Peutz-Jeghers syndrome, adrenal insufficiency and melanoma. We report a 58-year-old female with a 20-year history of Sjögren’s syndrome, presenting with melanonychia and hyperpigmentation in the buccal mucosa. She had no relevant medication history and is a non-smoker. The patient denied any other symptoms. The histopathology confirmed the diagnosis of Laugier-Hunziker syndrome.

A saúde bucal de crianças menores de 5 anos de idade no município de Diadema / Oral health status of children under 5 years-old in Diadema

O objetivo desse trabalho foi avaliar a prevalência, gravidade e os fatores associados à cárie dentária(CD), lesão dentária traumática (LDT) e desgaste dentário erosivo (DDEr) em crianças menores de 5 anos de idade no município de Diadema, São Paulo. Cirurgiões-Dentistas treinados e calibrados examinaram o total de 1215 crianças de 1, 2, 3 e 4 anos de idade para CD e LDT e 839 crianças de 3 e 4 anos de idade para DDEr nas 19 Unidades Básicas de Saúde, durante a campanha de Multivacinação Infantil, em 2012. Utilizou-se os índices de Knutson, ceo-d e ceo-s para CD, os critérios modificados de Andreas en para LDT e o índice de O´Brien modificado para DDEr. Foram realizadas análises descritivas e regressões de Poisson (IC 95%). As prevalências encontradas levando em consideração o totalda amostra examinada foram: CD (20,3%), LDT (20,1%) e DDEr (51,3%). Os fatores associados para CDforam a idade da criança e ter dois ou mais filhos na família; para LDT a idade e a presença de mordida aberta anterior e/ou sobressaliência acentuada; para DDEr consumir refrigerante e suco mais de 3 vezes ao dia, deixar a bebida na boca ou beber na mamadeira e relato de refluxo gastroesofágico. No município de Diadema, a prevalência de CD é baixa; LDT é moderada, sendo fratura de esmalte a mais frequente; DDEr é alta, no entanto a maioria das lesões acometem somente o esmalte.

This study aimed to assess the prevalence, severity and associated factors of Dental Caries (DC),Traumatic Dental Injury (TDI) and Erosive Tooth Wear (ETW) in children under 5 years-old in the municipality of Diadema, São Paulo. Trained and calibrated dentists examined a total of 1215 children aged 1-4years-old for DC and TDI, and 839 children aged 3 and 4 years-old for ETW in 19 Primary Health Centres during the National Children’s Vaccination in 2012. For the assessment of DC the Knutson, dmf-t and dmf-s indexes were used, a modified And reasen criteria was used for TDI and a modified version of theO’Brien index for ETW. Descriptive analysis and Poisson regression (CI 95%) were used. The prevalence of DC, TDI, ETW was 20.3%, 20.1% and 51.3% respectively. The Factors associated with DC were age and having more than one child in the family, for TDI the factors were age and presence of anterior openbite and/or increased overjet and for ETW, the factors were drinking soft drink or juice more than 3 timesa day, keeping it in the mouth without swallowing or using baby’s bottle, report of gastroesophageal reflux. In Diadema, the prevalence and severity of DC lesions is low; LDT is moderate enamel fracture being the most common; DDEr is high, however most lesions only affect the enamel.

Posible asociación autoinmune entre síndrome de Laugier-Hunziker y síndrome de Sjögren: reporte de un caso y revisión de la literatura / Laugier-Hunziker syndrome in a patient with Sjögren’s syndrome: report of one case

Laugier-Hunziker syndrome is a rare benign idiopathic condition characterized by acquired macular pigmentation of lips and buccal mucosa, often accompanied with melanonychia. The main concern with this condition is to rule out other differential diagnosis with systemic repercussions and similar hyperpigmentation patterns, such as Peutz-Jeghers syndrome, adrenal insufficiency and melanoma. We report a 58-year-old female with a 20-year history of Sjögren’s syndrome, presenting with melanonychia and hyperpigmentation in the buccal mucosa. She had no relevant medication history and is a non-smoker. The patient denied any other symptoms. The histopathology confirmed the diagnosis of Laugier-Hunziker syndrome.

Oral Manifestations of Inflammatory Bowel Diseases: Two Case Reports.

Inflammatory bowel diseases (IBD) are known as chronic inflammatory disorders of the digestive tract, represented mainly by Crohn's disease (CD) and ulcerative colitis (UC). Among the main oral manifestations of IBD are cobblestoning of the oral mucosa, labial swellings with vertical fissures, pyostomatitis vegetans, angular cheilitis, perioral erythema, and glossitis. In this sense, understanding these nosological entities by dentists would help reach early and differential diagnosis. Thus, two case reports are presented and discussed based on theoretical references obtained by a literature review. The first case report refers to an adult patient whose IBD diagnosis was established after stomatological assessment. The second case was a patient with CD diagnosed in childhood with characteristic oral lesions.

High Accuracy of Common HIV-Related Oral Disease Diagnoses by Non-Oral Health Specialists in the AIDS Clinical Trial Group.

OBJECTIVE: Many studies include oral HIV-related endpoints that may be diagnosed by non-oral-health specialists (non-OHS) like nurses or physicians. Our objective was to assess the accuracy of clinical diagnoses of HIV-related oral lesions made by non-OHS compared to diagnoses made by OHS. METHODS: A5254, a cross-sectional study conducted by the Oral HIV/AIDS Research Alliance within the AIDS Clinical Trial Group, enrolled HIV-1-infected adults participants from six clinical trial units (CTU) in the US (San Francisco, New York, Chapel Hill, Cleveland, Atlanta) and Haiti. CTU examiners (non-OHS) received standardized training on how to perform an oral examination and make clinical diagnoses of specific oral disease endpoints. Diagnoses by calibrated non-OHS were compared to those made by calibrated OHS, and sensitivity and specificity computed. RESULTS: Among 324 participants, the majority were black (73%), men (66%), and the median CD4+ cell count 138 cells/mm(3). The overall frequency of oral mucosal disease diagnosed by OHS was 43% in US sites, and 90% in Haiti. Oral candidiasis (OC) was detected in 153 (47%) by OHS, with erythematous candidiasis (EC) the most common type (39%) followed by pseudomembranous candidiasis (PC; 26%). The highest prevalence of OC (79%) was among participants in Haiti, and among those with CD4+ cell count ≤ 200 cells/mm(3) and HIV-1 RNA > 1000 copies/mL (71%). The sensitivity and specificity of OC diagnoses by non-OHS were 90% and 92% (for EC: 81% and 94%; PC: 82% and 95%). Sensitivity and specificity were also high for KS (87% and 94%, respectively), but sensitivity was < 60% for HL and oral warts in all sites combined. The Candida culture confirmation of OC clinical diagnoses (as defined by ≥ 1 colony forming unit per mL of oral/throat rinse) was ≥ 93% for both PC and EC. CONCLUSION: Trained non-OHS showed high accuracy of clinical diagnoses of OC in comparison with OHS, suggesting their usefulness in studies in resource-poor settings, but detection of less common lesions may require OHS.
