Gingiva is a common region of inflammatory and reactive lesions. Systemic conditions, including hormonal imbalance in pregnant women, may cause exaggerated response to irritations such as calculus or infection. Therefore, more accurate assessment is necessary to achieve the best decision making in the differential diagnosis and treatment of these patients. In this paper, we present a rea...

BACKGROUND Intraoral sebaceous carcinoma is a rare form of sebaceous carcinoma with only 9 published cases in the world literature to date. We present a 10th case of intraoral sebaceous carcinoma located in the anterior maxillary gingiva with metastases to the lung and subcutis and discuss 3 possible etiologies for this unique presentation. METHODS We analyze the clinical presentation, pathol...

BACKGROUND Acellular dermal matrix has been increasingly accepted in prosthetic breast reconstruction. Observed benefits include improved control and support of implant position, better implant coverage, and the suggestion of a decreased capsular contracture rate. Based on this positive experience, it is not surprising that acellular dermal matrix would be applied to other challenging implant-r...

There has been an increase in invasive breast carcinoma which many times end up with a mastectomy. The psychological effects of mastectomy can be overwhelming, urging the need for optimum reconstruction procedures. Acellular dermal matrices are widely used nowadays due to their favorable outcomes few complications. In this study, we review literature explore different types used, cons, and pros...

New acellular pertussis vaccines have recently been developed in China and India. In this context, potency testing and potential improvements of the protective animal models with inclusion of a reference material were recognized as critical issues in the quality assessment of acellular pertussis vaccines. One of these models, namely Modified Intracerebral Challenge Assay (MICA), is currently us...

The population-level safety benefits of the acellular pertussis vaccine may have been underestimated because only specific adverse events were considered, not overall impact on health services utilization. Using the Vaccine and Immunization Surveillance in Ontario (VISION) system, the authors analyzed data on 567,378 children born between April 1994 and March 1996 (before introduction of acellu...

OBJECTIVES/HYPOTHESIS To evaluate the effectiveness of free fat grafting in preventing Frey's syndrome (FS) and facial depression after parotidectomy compared with acellular dermis. METHODS A prospective randomized trial was performed. Patients who underwent parotidectomy were randomly assigned to abdominal free fat or acellular dermis grafting groups. The occurrence of FS, the aesthetic outc...

The acellular dermal matrix allograft has been used as an alternative to autogenous palatal mucosal graft. The aim of this study was the evaluation of the biocompatibility of an acellular dermal matrix (AlloDerm) in culture of macrophages. For hydrogen peroxidase determination we used the method of Pick & Kesari, and the Griess method for nitric oxide determination. Statistical analysis showed ...

Gingival augmentation procedures are indicated primarily to increase an insufficient amount of gingiva and sometimes to halt the progression of gingival recession. Inadequate or absence of attached gingival is considered detrimental to periodontal health by many researchers. Individuals with less than optimal oral hygiene practice can be helped by increasing the width of attached gingiva and ve...
