Unusual case of inflammatory myofibroblastic tumor in maxilla.

Inflammatory myofibroblastic tumor (IMT) is a rare lesion found mostly in children and young adults and originates from the lung, abdominopelvic region, and retroperitoneum. Clinical manifestations of IMT or imaging are nonspecific and diagnosis is based on histopathological and immunohistochemical findings. Minority of all IMTs will metastasize.

Comparison of the stability of bioabsorbable and titanium osteosynthesis materials for rigid internal fixation in orthognathic surgery. A prospective randomized controlled study in 101 patients with 192 osteotomies.

The purpose of this study was to evaluate the stability of rigid internal fixation in orthognathic surgery with either bioabsorbable or titanium osteosynthesis. Orthognathic surgery was performed on 101 patients. Bilateral sagittal ramus osteotomy was performed on 55 patients using bioabsorbable osteosynthesis in 26 and titanium osteosynthesis in 29 patients.

Differences in retinal neovascular tissue and vitreous humour in patients with type 1 and type 2 diabetes.

Aims: The aim of the study was to evaluate the histopathology of neovascular tufts and vitreous samples collected from patients with diabetes.

Methods: Vitreous samples and neovascular tufts were collected from patients with type 1 (n = 13) and (n = 17) type 2 diabetes with proliferative retinopathy, and from controls with a macular hole (n = 5). Neovessels were analysed using immunohistochemistry and vitreous samples with an enzyme-linked immunosorbent assay (ELISA).

Penetration of topically applied levofloxacin 0.5% and ofloxacin 0.3% into the vitreous of the non-inflamed human eye.

Background: The aim of the study was to evaluate the vitreous penetration of two commercially available ophthalmic fluoroquinolones: ofloxacin and levofloxacin.

Methods: This prospective, double-blind, randomized clinical trial comprised 16 patients scheduled for vitrectomy surgery of one eye for macular hole or macular pucker. The patients were randomly assigned to receive topical ofloxacin 0.

Mast cell subpopulations in gingival overgrowth induced by immunosuppressive and nifedipine medication.

Background: An immunohistochemical study was conducted to compare distributions of mast cell subpopulations in normal human gingiva and in gingival overgrowth induced by nifedipine and immunosuppressive medication.

Methods: Gingival samples were collected from 12 triple-medicated organ transplant recipients (immunosuppression group), 11 triple-medicated organ transplant recipients taking nifedipine (immunosuppression plus nifedipine group), 11 nifedipine-medicated cardiac outpatients (nifedipine group), and 20 generally healthy individuals (control group). Cryostat sections were stained with mAbs for tryptase and chymase, and an avidin-biotin enzyme complex method was used to detect tryptase-positive mast cells (MC(T)), tryptase- and chymase-positive mast cells (MC(TC)), and chymase-positive mast cells (MC(C)).
