Oral and dental abnormalities in Barber-Say syndrome.

A previously unreported case of Barber-Say syndrome is described with special attention to dental manifestations. A 7-year-old female with multiple congenital anomalies such mammary gland hypoplasia, hypertrichosis, ectropion, and redundant skin was seen at the School of Dentistry of the University of São Paulo. Oral examination revealed macrostomia, broad alveolar ridges, gingival fibromatosis, taurodontism, delayed tooth eruption, and malocclusion. Dental treatment included gingivoplasty and orthodontic treatment.

Osteonecrosis of the jaw in a patient under treatment of osteoporosis with oral bisphosphonate.

Although uncommon in patients under oral therapy, bisphosphonate-related osteonecrosis of the jaw (BRONJ) can be a very severe issue. Early intervention with surgical resection should be the preferable method of treating any stage of the disease, resulting in better outcomes and decreasing the morbidity of this condition. A 77-year-old female patient attended the Special Care Dentistry Centre of the University of São Paulo Faculty of Dentistry (CAPE FOUSP) complaining mainly of "an exposed bone that appeared after tooth extraction performed six months earlier". The patient was diagnosed with osteonecrosis associated with bisphosphonate (sodium ibandronate) and surgically treated with removal of bone sequestration and antibiotic therapy. The patient was followed up for six years (a total of 6 appointments), presenting good general health and no sign of bone exposure. Imaging findings showed no changes related to BRONJ either.

Can children be affected by bisphosphonate-related osteonecrosis of the jaw? A systematic review.

Knowledge of bisphosphonate-related osteonecrosis of the jaw (BRONJ) is mostly based on adult cases, however bisphosphonates are also currently recommended for different paediatric diseases resulting in osteoporosis. The aim of this study was to review the literature on the risk of developing BRONJ in children and adolescents. The PubMed, LILACS, Web of Science, Scopus, and Cochrane databases were searched using the key words "bisphosphonates", "osteonecrosis", "jaw", and "children". Literature reviews, case reports, abstracts, theses, textbooks, and book chapters were excluded. Studies involving children and young adults (younger than 24 years of age) were included. A total of 56 publications were identified. After applying the eligibility criteria, only seven articles remained. Although no cases of osteonecrosis were identified, all studies had weaknesses such as a limited sample size or the absence of risk factors for the development of osteonecrosis. There is general consensus that this subject should be of concern and that further studies should be conducted before any definitive opinion is reached. It is believed that patients with secondary osteoporosis who use bisphosphonates continuously should be followed up during adulthood, since bone turnover decreases over the years.

Dental implants in patients seropositive for HIV: A 12-year follow-up study.

BACKGROUND AND OVERVIEW: Patients seropositive HIV and AIDS represent a group of patients who experience longer longevity at the expense of effective therapies for infection control and related opportunistic diseases. However, the prolonged use of these drugs is often associated with adverse events, which theoretically may influence dental management and the long-term stability of dental implants. The objective of this study was to prospectively evaluate a group of HIV-positive people from a previous study who had received dental implants for 12 years after oral rehabilitation and functional loading. CASE DESCRIPTION: Nine patients with a total of 18 implants participated in this study. Viral load was undetectable in 8 patients, with 1 who had 48 copies/milliliter. The cluster of differentiation 4 T lymphocyte count ranged from 227 through 1,000 cells/cubic millimeter, mean (standard deviation [SD]) 564 (271.13) cells/mm3. Five of the 9 (55.5%) patients had visible plaque, and 5 (55.5%) had bleeding on probing with no implant mobility. Radiographs obtained at 6 months, 12 months, and 12 years of functional loading showed mean (SD) marginal bone losses of 0.32 (0.23) mm, 0.37 (0.23) mm, and 2.43 (1.48), respectively. CONCLUSION AND PRACTICAL IMPLICATIONS: These results suggest that dental implant treatment in HIV-positive patients achieved long-term survival, with a success rate comparable with that observed in healthy patients, indicating that implant rehabilitation is not a contraindication for HIV-positive patients.

An interesting case of systemic lupus erythematosus in a patient with Moebius syndrome.

Moebius' syndrome (MS) is characterized by a nonprogressive facial palsy associated with impairment in eye abduction, which can be uni- or bilateral. Some authors raise the possibility that patients with MS may suffer from social stigmatism due to their facial dysmorphism and that constant teasing and bullying perpetrated by people in the same social circle are adjuvants in the development of low self-esteem, behavioral problems, and even psychiatric disorders. Psychological stress, anxiety, and depression are factors contributing to both development and impairment of autoimmune diseases, such as systemic lupus erythematosus (SLE). The objective of this work is to report the case of a patient with MS who developed SLE. In the present case report, we have emphasized the importance of both clinical dental examination and surgeon-dentist in the early diagnosis of systemic diseases by considering that these conditions can affect both syndromic and normoreactive patients.

Periodontal status of liver transplant candidates and healthy controls.

BACKGROUND: This study aimed to compare the periodontal status of liver transplant candidates (LTCs) with healthy controls. METHODS: Fifty liver transplant candidates (LTC group) and fifty patients without liver disease (control group) underwent a complete periodontal examination. The groups were matched according to sex, age, and smoking status. A structured questionnaire was applied to record demographic data, systemic health, and information related to liver disease. Full-mouth complete periodontal examination of six sites per tooth was performed: gingival recession (GR), probing depth (PD), attachment loss (AL), bleeding on probing (BOP), and visible plaque index (VPI). The groups were compared in regard to periodontal clinical variables. RESULTS: Patients with cirrhosis had greater prevalence of periodontitis than healthy controls (P < 0.001). In addition, they had greater mean percentage of sites with AL ≥3 mm (P = 0.008) and AL ≥5 mm (P = 0.023), greater mean AL (P = 0.003), greater mean gingival recession (P < 0.001), and more missing teeth than in the control group (P = 0.02). CONCLUSION: Liver transplant candidates presented greater prevalence, extent, and severity of periodontitis than matched control patients.

Distraction osteogenesis in Goldenhar Syndrome: case report and 8-year follow-up.

Goldenhar syndrome is a well-known condition featuring the following triad of anomalies: ocular abnormalities, microtia and vertebral anomalies. This syndrome involves structures arising from the first and second branchial arches. Craniofacial anomalies, including mandibular, zygomatic and/or maxillary hypoplasias are found in 50% of patients with Goldenhar syndrome. Patients with this syndrome may present unilateral or bilateral underdevelopment of the mandible. Several treatments for the correction of the dento-facial deformity have been described, among them distraction osteogenesis is one that shows promising results. Distraction osteogenesis is the process of bone formation that occurs during slow separation of the segments of bone after an osteotomy and it has been used to alleviate facial asymmetry. Mandibular distraction osteogenesis has been applied for many years, but long-term reports present controversial results. The purpose of the case report is to describe the immediate and long-term effects of distraction osteogenesis used to treat mandible asymmetry in a 5-year-old boy with Goldenhar syndrome.

Oral plasmablastic lymphoma as the first manifestation of AIDS.

Plasmablastic lymphoma is a non-Hodgkin lymphoma characterized by its plasmacytic differentiation and predilection for the oral cavity. It is among the lymphomas most commonly associated with AIDS. This report details a case of a HIV-positive patient with a 1-month history of an exophytic mass in the gingival area of the upper left quadrant. The diagnosis of plasmablastic lymphoma was made based on its histopathological and immunophenotypical features. She was treated with chemotherapy followed by autologous hematopoietic stem cell transplantation. Despite complete resolution of the lesion, the patient died of cardiorespiratory arrest. This case illustrates plasmablastic lymphoma as the first clinical manifestation of AIDS, highlighting the importance of differentiating between a potentially malignant lesion and other pathologic processes.

Polyomavirus BK and JC in individuals with chronic kidney failure, kidney transplantation, and healthy controls.

BACKGROUND: New clinical approaches to diagnose and monitor individuals with systemic diseases have been employed through the use of oral fluids. Polyomavirus BK (BKPyV) and JC (JCPyV) infect asymptomatically around 80% of general population worldwide remaining latent in the body. In case of immunosuppression, a replication can occur, leading to diseases. OBJECTIVE: The aim of this study was to detect and quantify BKPyV and JCPyV in oral fluids of individuals with chronic kidney failure (CKF), kidney transplantation (KT) and controls compared with their detection in blood and urine, traditionally used for this test. STUDY DESIGN: Forty six subjects were included and distributed into 3 groups: 14 with CKF (Group 1), 12 with KT (Group 2) and 20 healthy individuals (Group 3). In a total, 315 samples were collected and analyzed through RT-PCR, being 151 of gingival crevicular fluid, 46 of saliva, 46 of mouthwash, 43 of blood and 29 of urine. RESULTS: All subjects from group 1 were positive for BKPyV in at least one collected samples and 14% were positive for JCPyV. In Group 2, 91.7% were positive for BKPyV and 51.7% for JCPyV. Among subjects of Group 3, 80% were positive for BKPyV and 45% for JCPyV. CONCLUSIONS: Oral fluids exhibited high prevalence of BKPyV and JCPyV and were equally efficient compared to urine and blood. The use of oral fluids to detect these polyomaviruses enhances positivity in screening, even in cases of absence of viremia and especially in individuals who are not able to urinate.

Treatment of central giant cell lesions using bisphosphonates with intralesional corticosteroid injections.

Central giant cell lesions are benign intraosseous proliferative lesions that have considerable local aggressiveness. Nonsurgical treatment methods, such as intralesional corticosteroid injections, systemic calcitonin and interferon have been reported. Recently, bisphosphonates have been used to treat central giant cell lesions. A case of a 36-year-old male with a central giant cell lesion crossing the mandibular midline was treated with intralesional corticosteroids combined with alendronate sodium for the control of systemic bone resorption. The steroid injections and the use of bisphosphonates were stopped after seven months when further needle penetration into the lesion was not possible due to new bone formation. After two years, the bony architecture was near normal, and only minimal radiolucency was present around the root apices of the involved teeth. The patient was followed up for four years, and panoramic radiography showed areas of new bone formation. Thus far, neither recurrence nor side effects of the medication have been detected.

Dental team management for a patient with Klippel-Feil syndrome: case report.

Klippel-Feil syndrome (KFS) is a rare congenital abnormality characterized by a short neck, a low posterior hairline, and limited head movement. Occasionally, patients with KFS may also show signs of deafness, intellectual disability, cardiac malformation, palpebral ptosis, facial nerve paralysis, cleft palate, and scoliosis. Although some researchers have documented this syndrome, scant attention has been paid to craniomaxillofacial manifestations and dental treatment of patients with KFS. The objective of this case report was to describe the planning and execution of dental treatment for a 10-year-old male patient with KFS.

Conhecendo o HTLV e suas implicações no atendimento odontológico / Getting to know HTLV and their implications during dental care

Os vírus T Linfotrópico humano representam um grupo de retrovírus que possuem tropismo por linfócitos T e são transmitidos pelas vias parenteral, vertical e sexual. Foram identificados os tipos 1, 2, 3 e 4 sendo que o vírus T Linfotrópico humano -1 tem sido o mais associado ao desenvolvimento de doenças nos pacientes infectados. A estimativa global é de que 15 a 20 milhões de pessoas estejam infectadas pelo vírus T Linfotrópico humano -1. No Brasil o vírus é endêmico, apresentando o maior número absoluto de casos no mundo e sendo incluído na triagem hematológica realizada nos hemocentros. As principais doenças associadas ao vírus T Linfotrópico humano -1 são a leucemia/linfoma de células T do adulto e a paraparesia espástica tropical. A única manifestação bucal associada ao vírus T Linfotrópico humano é o linfoma de células T do adulto, sendo que alguns autores apontam para a possibilidade de pacientes com paraparesia espástica tropical também apresentarem a síndrome de Sjõgren relacionada à infecção pelo vírus. O fato de o vírus T Linfotrópico humano ser um vírus contagioso e com capacidade oncogênica requer a atenção do cirurgião-dentista tanto no manejo odontológico quanto no diagnóstico de possíveis doenças associadas.

The human T-lymphotropic viruses represent a group of retroviruses that possess tropism for T lymphocytes and are transmitted parenterally, vertically and sexually. Four types have been identified, 1, 2, 3 and 4. Type 1 has been most frequently associated with disease in infected individuals. It is estimated that 15 to 20 million people are affected by human T-lymphotropic virus type 1. In Brazil, the virus is endemic, presenting the greatest absolute number of cases in the world and included in blood bank screening tests. The main diseases associated with human T-lymphotropic virus type 1 are adult T-cell leukemia/lymphoma and tropical spastic paraparesis. The only oral manifestation associated with human T-lymphotropic virus is adult T-cell lymphoma. Some authors believe it is possible for some patients with tropical spastic paraparesis to also present virus-related Sjõgren?s syndrome. Since human T-lymphotropic virus is contagious and potentially oncogenic, it demands attention from the dental surgeon not only for dental management but also for diagnosing associated diseases.

Condição bucal de hepatopatas pré- transplantados e transplantados hepáticos: revisão da literatura / Oral Health Status of liver transplant candidates and post–liver transplant patients: a literature review

O transplante de fígado é o tratamento preconizado para a doença hepática terminal. Infecções são complicações frequentes e estão associadas à alta morbidade e mortalidade de pacientes pré e pós-transplantados. Assim, a prevenção de processos infecciosos é fundamental para reduzir a progressão da cirrose e diminuir o risco de complicações após o transplante. Portanto, o objetivo desta revisão de literatura é verificar quais são as condições bucais de candidatos ao transplante de fígado e de pós-transplantados, bem como verificar se a doença hepática está associada com pior condição bucal. Os artigos incluídos demonstraram higiene bucal ruim, alta prevalência de doença periodontal e de doença cárie. Alguns estudos observaram maior perda óssea e maior perda de inserção clínica em pré e pós-transplantados do que em pacientes sadios. A literatura é controversa em relação à associação entre condição hepática e doença cárie. Não há evidência suficiente para suportar a hipótese de que a doença hepática seja um fator de risco para doenças bucais

Liver transplantation is the indicated treatment for endstage hepatic disease. Infections are frequent complications in patients waiting for liver transplant and post-transplant patients, and have been associated with high morbidity and mortality.Thus, prevention of infections is important in the reduction of the progression of hepatic disease and in the reduction of complications in the transplanted patient. The aim of the review is to describe the oral conditions of liver transplant candidates and transplanted patients, and to verify if hepatic disease is associated with poor oral conditions. The included articles demonstrated poor oral hygiene, high prevalence of periodontal disease and caries disease. Some of the studies observed greater bone loss and clinical attachment loss in liver transplant candidates and transplanted patients, when compared to healthy controls. The literature is controversial regarding association between liver disease and dental caries. We concluded that there is not enough evidence to support the hypothesis that liver disease increases the risk for oral diseases

Secondary syphilis in an HIV positive patient.

The incidence of oral manifestations of HIV infection is changing markedly. Oral afflictions previously uncommon in HIV condition are now emerging in this scenario and may be underestimated. Clinical characteristics of some oral diseases could change in the presence of HIV/AIDS infection and health care professionals must be made aware of such changes. Oral lesions of secondary syphilis are rare, however they can occur and the dentist should be able to diagnose them. In some cases the anamnesis and the clinical features of the lesions are not enough to diagnose this disease. Histological features and an acute knowledge on laboratory exams, as well as its applicability and limitations are necessary to diagnose it. The present report describes a case of secondary syphilis in an HIV positive patient. The patient showed red spots in the torso of skin and abdomen. The spots were also present on the hands but the color was darker. The oral mucosa had several ulcers, with variable shapes, sometimes recovered by a white and resistant membrane. They were present in the buccal mucosa, palate, gingiva, tongue and labial mucosa. Those clinical manifestations appeared 6 months earlier. Exams were performed (VDRL, FTA-abs, direct fungal exams in the skin and oral mucosa and a biopsy in the oral mucosa) but the diagnose remained unclear. Clinical and laboratory features disagreed and postponed the final diagnosis and the treatment for more than 6 months.

A odontologia hospitalar no serviço público do Estado de São Paulo / Hospital dentistry in the public service of the State of São Paulo

O projeto Sorria mais São Paulo, recentemente lançado pelo Governo do Estado, prevê, em uma de suas vertentes, a instituição da "Odontologia Hospitalar" e, visando a integralidade da atenção à saúde, incluiu o Cirurgião-Dentista (CD) à equipe hospitalar. O objetivo deste estudo foi mapear os atuais serviços de Odontologia na Rede Hospitalar Pública do Estado de São Paulo. Para tanto, foi consultado o Cadastro Nacional de Estabelecimentos de Saúde (CNES). A rede pública conta com 199 hospitais, sendo apenas 20% dos municípios contemplados. O Departamento Regional de Saúde I apresenta a maior concentração desses estabelecimentos (37). A esfera administrativa da maioria dos hospitais é privada (87,4%) e 66,3% são de gestão municipal, sendo que 17% atendem exclusivamente ao SUS. Existem 859 CDs contratados, porém mais da metade desses profissionais possuem perfil de atuação diferente do proposto pelo programa de "Odontologia Hospitalar". Em relação à jornada de trabalho, 58% trabalham menos de 20 horas semanais e pelo menos metade do tempo desses profissionais é destinado ao atendimento ambulatorial de pacientes. 58,20% dos CDs possuem vínculo de "autônomo", e 40,39% das contratações são intermediadas por entidades filantrópicas. Ao avaliar os CDs que possuem o perfil designado no programa "Odontologia Hospitalar", verifica-se que a relação leito/CD é de 87,57:1. Com CDs com uma carga horária pequena e dividida entre o atendimento ambulatorial e hospitalar, parece apropriado tanto à estruturação de novos serviços como o aumento de contratações específicas para suprir a demanda crescente desse profissional de saúde em hospitais.

The Sao Paulo state government recently began a project known as "Sorria Mais São Paulo" ("Smile More São Paulo"). which, among other measures, instituted a Hospital Dentistry Program within the state's public healthcare system. In an attempt to be more comprehensive, the state government has added dental surgeons (DSs) to hospital staff. The goal of this study was to chart the dentistry services available in Sao Paulo's public healthcare system. To do so, Brazil's National Health Establishment Registry (CNES) was consulted. The state's public healthcare network includes 199 hospitais, though only 20% of the state's cities are covered. The largest concentration of establishments (37) are in the DRS I region. In these hospitais, the administrative sectors are often private (87.4%). 66.3% are under city management, and 17% are exclusively public hospitais. Though 859 DSs have been hired, more than half of them per- form tasks that were not proposed by the Program, 58% work fewer than 20 hours per week, and more than half of their time is spent on ambulatory care services. Of these DSs, 58.20% are considered "independent contractors." and 40.39% of their hirings are initiated by philanthropic entities. When one considers only the DSs that perform the tasks of the Program, the ratio of hospitalized patients to doctors is 87.57:1. With DSs working few hours and dividing their time between surgery and ambulatory care, it seems that the state needs to develop new servicesand increase hirings in order to meet the demand for these healthcare professionals.

Manejo clínico ambulatorial do paciente portador de hepatite viral / Clinical management of patients with viral hepatitis

O fígado pode ser afetado por agentes químicos, físicos ou biológicos. Atualmente, aceita-se a existência de 9 vírus hepatotrópicos capazes de causar hepatites virais. Independentemente do tipo de hepatite viral, as alterações hepáticas podem estar presentes no paciente e representar distúrbios funcionais importantes. O cirurgião-dentista deve estar apto a tratar o paciente hepatopata, sendo capaz de avaliar as alterações sistêmicas relacionadas ao mau funcionamento do órgão.
