Clinical evaluation of chemiluminescent lighting: an adjunct for oral mucosal examinations.

OBJECTIVE: The purpose of this study was to describe the utility of oral chemiluminescent lighting (FDA-cleared ViziLite) as an adjunct to standard visual examination (SVE) to enhance visualization of mucosal lesions, particularly those "clinically suspicious" for oral pre-cancer or cancer. Subjects were considered at risk for oral cancer or pre-cancer if they have no a priori knowledge of the presence or absence of an oral lesion at the time of examination. METHODOLOGY: Five-hundred and one consecutive consenting subjects, over 40 years of age and with a positive tobacco history, received a standard visual examination with conventional incandescent lighting, followed by chemiluminescent lighting. All lesions were recorded, and for lesions detected by both screening modalities, comparisons were made of the subjective parameters of lesion brightness, sharpness, surface texture, and relative size. RESULTS: A total of 410 epithelial lesions were detected in 270 subjects by standard visual examination, of which 127 were clinically "suspicious" for oral cancer and pre-cancer. Ninety-eight lesions were also visualized by chemiluminescent lighting as "aceto-white" (CL+), in addition to six lesions not previously seen by standard visual examination. Seventy-seven of the CL+ lesions (78.5%) were clinically suspicious; all "suspicious" lesions with an ulcerative component and ulcerated lesions consistent with trauma were CL+. Leukoplakias were significantly more likely to be CL+ than erythroplakias (p < 0.01). Overall, those lesions illuminated by chemiluminescent lighting appeared brighter, sharper, and smaller compared to incandescent illumination. CONCLUSION: The results of this study suggest that oral chemiluminescent lighting, when used as a screening adjunct following the standard visual oral examination, provides additional visual information. Leukoplakias may be more readily visualized by chemiluminescence. Studies are underway to explore the clinical significance and predictive value of oral chemiluminescent lighting.

Locally aggressive solitary fibrous tumor in the infraorbital region: a case report and review of the literature.

We describe a case of a soft tissue neoplasm in the infraorbital region of a 31-year-old African-American man that met histologic and immunohistochemical criteria for solitary fibrous tumor. This uncommon spindle cell neoplasm was first described in the pleura, but it has since been reported in many other soft tissue locations. The lesion was locally aggressive and successfully treated by local excision. Solitary fibrous tumor can be locally destructive and can occur in a wide variety of tissues or organs; this is the seventh published case of solitary fibrous tumor in the orofacial region.

Clinicopathological findings consistent with primary Sjögren's syndrome in a subset of patients diagnosed with chronic fatigue syndrome: preliminary observations.

OBJECTIVE: Some patients diagnosed with chronic fatigue syndrome (CFS) have symptoms commonly observed in Sjögren's syndrome (SS), particularly xerophthalmia and xerostomia, leading to speculation that some patients with CFS might have primary SS or that the 2 disorders share common pathophysiological features. We investigated the prevalence of symptoms of mucosal dryness, salivary gland pathology, lacrimal hyposecretion, and autoantibodies (antinuclear antibody, SSA/SSB) among patients diagnosed with CFS. METHODS: Twenty-five subjects with CFS and 18 healthy control subjects were interviewed and examined, had a Schirmer test and fluorescein tear dilution, and underwent minor salivary gland (MSG) biopsy. Antibody to nuclear antigen as well as anti-La (SSA) and anti-Ro (SSB) antibody were available for subjects with CFS. Pathologists unaware of the subject group assignment examined labial salivary gland biopsy specimens and calculated a standard MSG score for each specimen. RESULTS: Mucosal dryness was reported by 13/25 (52%) subjects with CFS, of which 8 (32%) also had MSG score, low Schirmer test value, and symptoms consistent with primary SS (p = 0.05). No control subject met diagnostic criteria for primary SS. MSG focus scores < or =1 were common among both groups (CFS 14/25; controls 15/18). MSG results without pathological alteration were rare, seen in only one control and no CFS patients. Low Schirmer values were found in 10/25 (40%) CFS patients and 1/18 (6%) control (p = 0.01). CONCLUSION: A subset of patients with CFS may have primary SS.

Chronic oral mucosal ulceration in a 54-year-old female.

Pemphigus vulgaris most often begins in the mouth but is often overlooked in the differential diagnosis of chronic, multiple oral ulcerations and erosions. Accurate diagnosis requires perilesional biopsy including intact epithelium, submitted for hematoxylin and eosin as well as direct immunofluorescence staining. Early and aggressive treatment with moderate to high dose prednisone in combination with steroid sparing drugs such as azathioprine and mycophenolate allow complete remission in most patients.

Oral manifestations of HIV disease.

Oral disease is frequently associated with HIV. While nearly all oral disorders associated with HIV infection also occur in other conditions characterized by immunosuppression, no other condition is associated with as wide and significant a spectrum of oral disease as is HIV infection. Many HIV-associated oral disorders occur early in HIV infection, not infrequently as the presenting sign or symptom. Thus, early detection of associated oral disease should, in many cases, result in earlier diagnosis of HIV infection. Likewise, awareness of the variety of oral disorders which can develop throughout the course of HIV infection, and coordination of health care services between physician and dentist, should improve overall health and comfort of the patient. This paper reviews the clinical, diagnostic and therapeutic aspects of HIV-associated oral disorders.

Oral manifestations of cutaneous T-cell lymphoma. A report of eight cases.

Cutaneous T-cell lymphoma rarely involves the oral cavity. Only 14 detailed cases of oral cutaneous T-cell lymphoma have been described in the English-language literature; this report describes eight additional cases observed among 824 patients evaluated at our cutaneous T-cell lymphoma center since 1968. Oral involvement occurs late in the course of cutaneous T-cell lymphoma and usually is associated with poor prognosis; most patients die of disease complications within 3 years of the diagnosis of oral involvement.

Maxillofacial plasmacytoma resulting in intraoral hemorrhage in a patient with multiple myeloma.

Oral symptoms of multiple myeloma are common. A patient with refractory multiple myeloma is described because of this unusual orofacial manifestations, including severe intraoral hemorrhage, a massive, erosive maxillofacial lesion with extension into the cranial fossa, and rapid growth of a large intraoral mass.

The differentiation of intraoral ulcers.

Oral lesions commonly seen by primary care physicians represent manifestations of local or systemic disease of infectious, immunogenic, malignant, or traumatic etiology. The patient's history will readily show whether the lesions are acute or chronic, single or multiple, primary or recurrent--classifications that greatly simplify the differential diagnosis.
