Burkitt's lymphoma in a patient presenting with inferior alveolar nerve hypoesthesia in the absence of a regional tumor

Burkitt's lymphoma is a malignant lymphoma of high malignancy grade and accounts for less than 1% of all cases of malignant lymphoma. Patients with malignant lymphoma in the oral and maxillofacial region including Burkitt's lymphoma, frequently present with gingival swelling, or a tumor mass/ulcers as the initial symptoms. We present an extremely rare case with bilateral mental nerve paralysis as the initial symptom without not only regional tumor but also brain and nose-pharyngeal area. This report indicates that the unexplained oral abnormalities such as inferior alveolar nerve hypoesthesia must be considered, potentially prodromal symptoms of Burkitt's lymphoma. © 2010 Asian Association of Oral and Maxillofacial Surgeons.

In this study, we investigated the use of perforated sheet platforms to improve the attachment of percutaneous devices to surrounding tissues. The model platform was created by a poly(methyl methacrylate) (PMMA) sheet with a matrix of 200-μm diameter perforations covering the groove (width, 3 mm; depth, 0.5 mm) prepared on the PMMA cylinder (diameter, 10 mm; length, 6 mm). Velour cuffs from peritoneal dialysis catheters were used as controls. Specimens were implanted percutaneously in rats, harvested with the surrounding tissues at 4 weeks after surgery, and subjected to mechanical tests and histological observations. The attachment strength of the experimental specimens to tissue was 138.4 ± 123.6 kPa (n = 5, mean ± SD); although it was greater than the 67.23 ± 45.78 kPa (n = 5) of the controls, no statistical significance was found. Histological observations of the experimental specimens revealed the collagen fibers originating from the surrounding tissues, passing through the perforations of the sheet, merging into the collagen fibers running behind the sheet, and thus anchoring the tissues to the device. In contrast, such anchoring of collagen fibers was not evident in the controls. These results suggest that the proposed perforated sheet structures are effective for soft tissue attachment.

Objectives: Increase of soft tissue attachment is a major concern for improving the design of novel dental implants. This study evaluated the use of mesh structures placed on the implant surface for the anchorage of fibrous tissues. Material and methods: Specimens were prepared by covering their surfaces with a nylon mesh. The following mesh spacings were used: 30, 46, 100, 200, and 500 μm. The specimens were retrieved along with the surrounding subcutaneous tissues at 4 weeks after their implantation into the dorsal subcutaneous tissues of rats. A tensile test was performed by using a material testing machine, and the load required to tear the tissue from the mesh was measured. Histological sections stained with hematoxylin-eosin or Azan were prepared and examined by performing light microscopy. The amount of fibrous tissue contributing to the mechanical attachment of the fibers to the mesh was qualitatively evaluated by performing image analysis. Results: The attachment strength was the greatest in the 200-μm mesh-spacing group and considerably greater than that in the 30-μm mesh-spacing group. In addition, the effective width of the anchoring fibrous tissues was the greatest in the 200-μm mesh-spacing group. As compared with the other groups, the 200- and 500-μm mesh-spacing groups exhibited a considerably greater width of the anchoring fibrous tissues. Conclusions: The efficiency of mesh structures for the attachment of soft tissues to implants was demonstrated. A mesh spacing of approximately 200 μm was observed to be favorable for the anchorage of fibrous tissues. © 2008 The Authors.
