Antimicrobial photodynamic therapy using optical fiber for oral fistula resulting from mandibular osteoradionecrosis.

Osteoradionecrosis (ORN) is considered one of the most severe complications of radiotherapy (RT). Treatment modalities for ORN may vary considerably, including conservative or surgical procedures. Recently, alternative managements such as the combination of photobiomodulation therapy (PBMT) and antimicrobial photodynamic therapy (aPDT) have also yielded promising results in patients presenting ORN or delayed healing post-RT. Herein, it is reported a case of ORN manifested as an oral fistula on the mandibular alveolar mucosa in which a combination of PBMT and aPDT was used every 15 days for six weeks. A laser device with an optical fiber was introduced into the fistula for light delivery. Seven days after the first laser session, it was noted complete resolution of both edema and erythema; after six weeks, the ORN fistula was no longer present. According to the current case, the combination of PBMT and aPDT with an optical fiber to deliver the laser light seems to be a suitable alternative for restricted areas such as fistula paths.

[Multiple intra-oral fistulae]. / Multipele intraorale fistels.

A 20-year-old man presented with multiple intra-oral fistulae in the anterior part of the mandible. The patient was diagnosed with secondary osteomyelitis. Microbiologic survey revealed positive cultures for Staphylococcus aureus, Haemophilus para-influenzae and alpha-haemolytic streptococci. After sequestrectomy and decortication, the mobile teeth were splinted. The patient was treated with intravenous antibiotics, followed by long-term oral antibiotics. Complete healing was achieved.

[Conservative treatment of a case of periapical lesion with complications. Report of a case and calcium hydroxide therapy]. / Szövödményes periapicalis elváltozás konzervatív kezelése. Egy eset kapcsán a kalcium-hidroxidról.

A case and treatment of extraoral fistula on the chin-caused by necrotic pulp of lower left canine--is being presented. In this case an endodontic origin should always be considered from the aspect of differential diagnosis. Nonsurgical endodontic therapy, sometimes complimented by surgery, or extraction are the treatment modalities of these cases. For the treatment calcium hydroxide powder mixed with chlorhexidin gluckonat (0.1%) was used. Usage of calcium hydroxide paste was leaded to rapid and successful healing of extraoral lesions communicating with necrotic tooth.

The management of fistulizing oral Crohn's disease with infliximab.

A 20-year-old female patient with oral Crohn's disease developed a fistula in her neck from a focus of intra-oral infection. Despite repeated courses of antimicrobial therapy over a period of several months, the fistula failed to resolve. However, following administration of infliximab, a monoclonal antitumour necrosis factor-alpha antibody, the fistula resolved spontaneously without the need for any further treatment.

Miíase órbito-maxilo-bucal: relato de um caso / Orbital-maxillobucal myiasis: report of a case

Os autores apresentam um caso de oftalmomiíase com fístula orbito-maxilo-bucal por larvas da espécie Dermatobia hominis. O tratamento clínico foi realizado com éter sulfúrico, para retirada das larvas, curativos com óxido amarelo de mercúrio 1 por cento e medicação sistêmica que incluía antibiótico e antiinflamatório via oral. Apesar da resolução satisfatória com involução espontânea da fístula, foi necessária enucleação do globo ocular.
