Lipomas are benign soft tissue tumours composed mainly of mature adipose tissue. Histological variants of lipomas have been named according to the type of tissue present and they include fibrolipoma, angiolipoma, osteolipoma, chondrolipoma and others. Osteolipoma, a classic lipoma with osseous metaplasia, is a very rare histological variant. Owing to the rarity of oral osteolipomas, we report an uncommon case of osteolipoma located on the floor of the mouth of a 20-year-old female patient and include a review of the literature.

Disorders relating to short gestation and low birth weight are among the leading causes of death and disability in infants. About 25% of pre-term low birth weight (PLBW) cases occur without even a suspected risk factor. Of all PLBW cases, 18.2% may be attributable to periodontitis (Offenbacher et al. 1996). Therefore, this study was conducted to assess the views and knowledge of gynaecologist's on association between periodontal disease and pre-term low birth weight and their willingness to advise their patients to seek dental treatment. © 2011 Informa UK, Ltd.

Objectives: The present study was undertaken to assess and compare the immunohistochemical expression of Bcl-2 in selected benign and malignant salivary gland tumors. Study Design: A total of 50 cases of buffered formalin-fixed, paraffin embedded tissues of previously diagnosed cases of benign and malignant salivary gland tumors from the archives of Department of Oral and Maxillofacial Pathology and Microbiology, SDM College of Dental Sciences and Hospital, Dharwad, India, were taken for the study. The immunohistochemical staining procedure was performed using monoclonal anti Bcl-2 antibody, as directed by the manufacturer. Results: Thirty six cases (72%) out of 50 cases showed a positive expression for Bcl-2. Benign salivary gland tumors showed a positive expression in 8 out of 14 cases (~57%) and malignant salivary gland tumors in 28 out of 36 cases (~78%). The staining was intense in the normal lymph node, which is used as a positive control. Bcl-2 expression was seen in both benign and in malignant salivary gland tumors taken for the study except in "canalicular adenoma". Conclusion: The immunohistochemical expression of Bcl-2 was greater and more intense in malignant salivary gland neoplasms, suggesting a high survival rate of tumor cells in malignant neoplasms. © Medicina Oral S.

To describe the different patterns of the intraoral distribution of enamel fluorosis in permanent dentition. This cross-sectional analysis was conducted in Nalgonda district of Andhra Pradesh, India. A group of 1000 school children aged 13-15 years were selected by stratified cluster sampling from four different areas with different levels of naturally occurring fluoride in the drinking water. Fluorosis was recorded using the Thylstrup and Fejerskov index (TFI). The prevalence of fluorosis (TFI score >=1) was 100% at all four fluoride levels. This study revealed two patterns of fluorotic enamel changes in dentition. In high fluoride areas, incisors exhibited lower TFI values than canines, premolars and molars, with the maximum affected being second molars followed by first molars. In low fluoride areas, a steeper profile of dental fluorosis, starting from incisors and first molars through canine and premolars to second molars, was noticed. With the exception of permanent second molars and permanent first molars in high fluoride communities, the intraoral distribution of different degrees of dental fluorosis was related to the completion of primary enamel formation.

Sympathetic ophthalmia (SO), also known as sympathetic uveitis, is a rare bilateral granulomatous panuveitis that occurs after a penetrating injury to an eye. After injuryfrom either surgery or accident, a variable period of time passes before a sightthreatening inflammation develops in both the eyes. The disease usually responds rapidly to corticosteroid therapy, but recalcitrant cases may require the addition of other immunosuppressive agents. A severely injured eye with no prognosis for vision should be enucleated within 2 weeks of injury to prevent SO. The purpose of this article is to highlight the risks of SO associated with the orbital fractures involving soft tissue components of the orbit. Though unusual, a maxillofacial surgeon, while operating on the orbital walls involving the soft tissue disruption, has to be aware of this condition so that the postoperative complications related to vision can be avoided. © 2012 Elsevier, Inc.
