Intranasal tooth and associated rhinolith in a patient with cleft lip and palate

We report the case of a 9-year-old girl who presented with a complaint of a malodorous bloody discharge from the left naris. The patient had previously undergone a complete repair of left-sided cleft lip and palate. Clinical examination revealed hyperplasia of the nasal mucosa on the left side. X-ray examination of the nasal cavity demonstrated a radiopaque structure that resembled a tooth and a radiopaque mass similar to an odontoma that was adherent to the root of the suspected tooth. With the patient under general anesthesia, the structure was removed. On gross inspection, the structure was identified as a tooth with a rhinolith attached to the surface of its root. Microscopic examination revealed normal dentin and pulp tissue. A nonspecific inflammatory infiltrate was observed around the rhinolith, and areas of regular and irregular mineralization were seen. Some mineralized areas exhibited melanin-like brownish pigmentation. Areas of mucus with deposits of mineral salts were also observed. Rare cases of an intranasal tooth associated with a rhinolith have been described in the literature. We believe that this case represents only the second published report of an intranasal tooth associated with a rhinolith in a patient with cleft lip and palate

Peripheral compound odontoma erupting in the gingiva

Background: Peripheral odontoma arising in the extraosseous soft tissues is rare and if not removed early, may enlarge over time and eventually erupt in the oral cavity. Case presentation: A 15-year-old girl presented with “denticles on the gingiva”. During the intraoral examination, seven small tooth-like structures were found. These were exposed in the anterior left gingiva between the permanent maxillary lateral incisor and canine teeth, and the left first premolar was absent. Radiographic examination revealed irregular tooth-like structures without evidence of bone involvement. Conclusion: The lesion was surgically removed, and the specimens were analyzed histopathologically. The diagnosis of compound odontoma was established. Clinical significance: This is the twelfth reported case of peripheral odontoma in the gingiva and the first one that erupted in the oral cavity.

Drug reaction with Eosinophilia and Systemic Symptoms (DRESS) / Drug-induced Hypersensitivity Syndrome (DIHS): a review of current concepts

The Drug Reaction with Eosinophilia and Systemic Symptoms syndrome, also known as Drug Induced Hypersensitivity Syndrome presents clinically as an extensive mucocutaneous rash, accompanied by fever, lymphadenopathy, hepatitis, hematologic abnormalities with eosinophilia and atypical lymphocytes, and may involve other organs with eosinophilic infiltration, causing damage to several systems, especially to the kidneys, heart, lungs, and pancreas. Recognition of this syndrome is of paramount importance, since the mortality rate is about 10% to 20%, and a specific therapy may be necessary. The pathogenesis is related to specific drugs, especially the aromatic anticonvulsants, altered immune response, sequential reactivation of herpes virus and association with HLA alleles. Early recognition of the syndrome and withdrawal of the offending drug are the most important and essential steps in the treatment of affected patients. Corticosteroids are the basis of the treatment of the syndrome, which may be associated with intravenous immunoglobulin and, in selected cases, Ganciclovir. The article reviews the current concepts involving this important manifestation of adverse drug reaction.

Irrupção dentária estimulada pelo enxerto ósseo alveolar na região da fissura

Introdução: Esse trabalho tem como objetivo relatar um caso clínico de irrupção dentária estimulada após a realização de enxerto ósseo alveolar num paciente com fissura transforame unilateral. Relato clínico: Paciente DMS de 8 anos de idade compareceu ao setor de Ortodontia para dar início ao tratamento. Verificou-se a presença de fissura transforame unilateral direita, padrão esquelético Classe I, mordida cruzada posterior unilateral direita e presença de dentes supranumerários na região da fissura. Após o planejamento, foi realizada a Expansão Rápida da Maxila com HAAS borboleta seguida da instalação de contenção fixa. O Enxerto Ósseo Alveolar foi realizado posteriormente, a fim de corrigir o defeito ósseo causado pela fissura e favorecer a irrupção dos dentes adjacentes a essa região, possibilitando uma adequada finalização ortodôntica. Resultados obtidos: Após a realização do Enxerto Ósseo Alveolar e reanatomização dos dentes satisfatoriamente irrompidos na região da fissura, verificou-se uma adequada harmonia funcional e estética, também favorecida pela ortodontia corretiva. Conclusões: A presença de dentes na região da fissura constitui um fator que ocorre comumente e deve ser ponderado a fim de possibilitar melhores resultados no tratamento destes pacientes.
