Prophylactic photobiomodulation therapy using 660 nm diode laser for oral mucositis in paediatric patients under chemotherapy: 5-year experience from a Brazilian referral service.

The use of photobiomodulation therapy (PBMT) in the prevention of oral mucositis (OM) in paediatric care has increased. In this article, we report data of paediatric oncology/haematopoietic stem cell transplantation (HSCT) patients treated with PBMT to prevent chemotherapy-induced OM. A retrospective study was conducted at a Brazilian referral service.

Acinetobacter baumannii orofacial cellulitis: report of 2 cases.

Acinetobacter baumannii infection of skin and soft tissues is uncommon and usually associated with trauma. The present report describes 2 pediatric cases of cellulitis in the orofacial region, caused by A. baumannii infection with a fatal outcome.

Treatment of oral manifestations of toxic epidermal necrolysis with low-level laser therapy in a pediatric patient.

Drug-induced reactions are complications associated with high mortality and significant morbidity. Stevens-Johnson Syndrome (SJS) and toxic epidermal necrolysis (TEN) are examples of these conditions, which are characterized by skin and mucous lesions. Here, we report a case of a 9-year-old girl who presented with blisters associated with an extensive vesicular rash and multiple ulcerations on the lips and oral cavity.

Intraoral granulocytic sarcoma as a manifestation of myelofibrosis: A case report and review of the literature.

Granulocytic sarcoma (GS) is an extramedullary tumor associated with myelodysplastic syndromes or myeloproliferative diseases. Intraoral manifestations are considered uncommon, with a reasonable number of cases, and are mostly related to leukemia. The association of oral GS and myelofibrosis is very rare and only three cases have been published.

Mature dendritic cell density is affected by smoking habit, lesion size, and epithelial dysplasia in oral leukoplakia samples.

Objective: To compare the densities of CD1a + immature and CD83+ mature dendritic cells, and inflammatory infiltrate cells between smokers and non-smokers with oral leukoplakia. Parameters associated with malignant transformation were also evaluated.

Design: 21 smokers and 23 non-smokers diagnosed with oral leukoplakia were obtained.

Retrospective Study of 383 Cases of Fibro-Osseous Lesions of the Jaws.

Purpose: The aims of this study were to describe the clinical and radiologic features of 383 fibro-osseous lesions (FOLs) from an oral pathology reference service in Brazil and to compare the findings with previous studies. The hypothesis of the study was that the most common type of FOL would differ from other investigations.

Materials And Methods: We conducted a descriptive and retrospective study with review of the records of the clinical and biopsy services (1990 to 2015).

CD1a+ dendritic cells in oral lichen planus and amalgam lichenoid reaction.

Objective: To evaluate and compare the number of CD1a+ dendritic cells (DCs) in oral lichen planus (OLP), amalgam lichenoid reaction (ALR), and normal oral mucosa (NOM).

Study Design: Fourteen cases of OLP and ALR, diagnosed both clinically and histologically, were obtained from an archive of an oral pathology service. Seven specimens of NOM were collected and served as controls.
