Extensive oral lesion colonized with 601 myiasis larvae.

Myiasis is a type of infection caused by the larvae of flying insects. This paper reports a case of a 72-year-old Caucasian man who was referred to the Infectology Department of Oswaldo Cruz University Hospital (Pernambuco-Brazil) for urgent treatment as he was malnourished and dehydrated. He had a facial and buccal lesion colonized with larvae and was extremely debilitated. The surgical and clinical treatment indicated at the first moment was the surgical removal of the larvae. But, after two days, some larvae were still present and therefore 12 mg of ivermectin was administered. At the end of the treatment, 601 larvae had been removed and the therapeutics established were suitable.

Treatment of chronic mandibular dislocations using miniplates: follow-up of 8 cases and literature review.

Temporomandibular joint (TMJ) dislocation is an excessive forward movement of the condyle beyond the articular eminence with complete separation of the articular surfaces and fixation in that position. This study reports 8 cases using miniplates for chronic mandibular dislocations, evaluates the results and critically reviews the literature. The sample was obtained from the records of the Oswaldo Cruz University Hospital and comprises patients undergoing chronic mandibular dislocation treatment using 2.0mm titanium miniplates between August 2002 and March 2004. Pre- and postoperative assessment included a thorough history and physical examination to determine the maximal mouth opening, presence of pain and sounds, frequency of luxations, recurrence rate and presence of facial nerve paralysis. The mean maximal mouth opening preoperatively was 42.75+/-11.53 mm and was 45.62+/-8.52 mm postoperatively. There was no facial nerve paralysis. Miniplate fracture was observed in 2 cases and there was one recurrence. Treating chronic mandibular dislocation using miniplates was shown to be efficient in relation to postoperative maximal mouth opening, recurrence and articular function, however, the possibility of the miniplate fracturing must be considered.
