Metastatic malignant melanoma of the oral cavity. A retrospective study.

Metastatic malignant melanoma of the oral cavity is rarely reported in the dental literature. This retrospective study identified metastatic oral lesions in 3.0% of 809 patients with melanoma treated at the National Institutes of Health between 1953 and 1989. Fifteen cases met established rigorous criteria for metastatic tumors and were reviewed for disease course and outcome. Nine white men and six white women, with an average age of 40.6 years, had cutaneous primary tumors predominantly of the trunk and head and neck region that commonly presented as moles that were enlarging, bleeding, or showing both of these signs. A mean of 4.2 years elapsed between primary tumor and oral metastasis diagnosis. Tongue, buccal mucosa, and parotid gland were the predominant oral sites. Enlarging oral masses, pigmented lesions, and nonhealing extraction sites with masses were common oral presentations. Surgery, chemotherapy, radiation therapy, and immunotherapy were used in various combinations for treatment of the primary lesion and oral metastasis. Prognosis, although poor, was highly variable.

Embryonal rhabdomyosarcoma of the floor of the mouth. A case report.

Rhabdomyosarcoma is a neoplasm composed of striated muscle. One of the most common types of soft tissue mesenchymal tumors in infants, children, and adolescents, rhabdomyosarcoma was considered an almost uniformly fatal cancer as recently as 30 years ago. Presently a multimodal approach consisting of surgery, radiation, and chemotherapy has significantly improved the outlook for the patient with rhabdomyosarcoma. This article presents a case of intraoral rhabdomyosarcoma that was initially poorly controlled because of a lack of patient compliance. After proper treatment, the cancer went into remission. The patient remained cancer-free for 7 years, albeit with significant morbidity. This case demonstrates the significantly improved prognosis achieved with multimodal therapy.

Body and orofacial cathexis in edentulous complete-denture-wearing clients.

This description cross-sectional study examines cathexis, or satisfaction, with the body and the orofacial region in relationship to eight major demographic and health status variables in a nonprobability sample of 34 male and 47 female edentulous subjects aged 36 to 77 years. Kiyak's 27-item Body Cathexis Scale (BCS), including an innovative five-item Orofacial Cathexis Scale (OFCS), was shown to be reliable for use in elderly clients at least to age 77 (Cronbach's alpha = .95). More research is needed to validate the OFCS. Overall scores were in the neutral range, with teeth being the most negatively cathected body part. Longer periods of edentulism were associated with more dissatisfaction with the teeth. Body and orofacial cathexis were highly positively correlated. Chronic illness, education level, race, and religion were not significantly related to cathexis. Edentulism, especially recent edentulism in the elderly, female gender, and divorced marital status could be important indicators for body image disturbance.

Implant rehabilitation in Erdheim-Chester disease: a clinical report.

Successful osseointegration of endosseous titanium implants is thought to be dependent upon close apposition of bone to the implant surface. The integration of implants in this patient was achieved despite the lipid-laden histiocytic infiltration of the bone marrow. Presumably, enough unaffected stromal cells were present to allow sufficient bone formation for osseointegration of the implant fixtures. This result invites speculation regarding both the mechanism of osseointegration and the minimum surface area of bone-implant interface necessary for achieving and maintaining osseointegration of titanium implants. This patient is periodically examined to determine if the loaded fixtures will remain clinically immobile for a prolonged period.

Human immunodeficiency virus (HIV) and HIV infected cells in saliva and salivary glands of a patient with systemic lupus erythematosus.

A young woman with systemic lupus erythematosus (SLE) was infected with human immunodeficiency virus 1 (HIV-1) and about 6 years later developed persistent bilateral parotid gland enlargement. It was unclear whether this represented salivary gland involvement as a component of her SLE (secondary Sjögren's syndrome) or the initial clinical manifestation of her HIV-1 infection. HIV proviral DNA was found in individual salivary glandular secretions and in whole saliva. Additionally, cells positive for HIV RNA were isolated from whole saliva. A parotid gland biopsy revealed infiltrating lymphocytes containing large amounts of HIV RNA.

Using endosseous dental implants for patients with ectodermal dysplasia.

Congenitally missing teeth and poorly developed or absent alveolar ridges are signs often associated with various types of ectodermal dysplasia. Endosseous dental implants may be used to support fixed mandibular prostheses in patients with ectodermal dysplasia. Anatomical factors and age considerations require careful attention to treatment planning.

Oral squamous cell carcinoma arising in a patient with long-standing lichen planus. A case report.

The risk of malignant transformation of oral lichen planus remains a controversial point. Many previous reports have been discounted on the basis of inadequate information or lack of histologic confirmation of lichen planus. We report a well-documented case of long-standing cutaneous and oral lichen planus in which squamous cell carcinoma of the dorsal portion of the tongue occurred. There is an apparent difference in the sites of oral carcinomas in patients with lichen planus compared with the general population. This suggests that lichen planus increases the risk of oral cancer in affected sites.

Failure of surgery and isotretinoin to relieve jaw immobilization in fibrodysplasia ossificans progressiva: report of two cases.

Two patients with fibrodysplasia ossificans progressiva who presented with jaw immobilization due to formation of bone between the maxilla and mandible were treated with surgical resection of their ectopic bone in conjunction with experimental, adjunctive medical therapy using isotretinoin. Both patients had recurrence of their ectopic ossification within 2 months of surgery. Surgery to remove joint-bridging ossifications in FOP is not recommended.

Oral manifestations of human immunodeficiency virus infection.

It is important that both physicians and dentists recognize the earliest signs of HIV infection in order that a timely diagnosis and patient referral can be made for counseling and treatment. Candidiasis, hairy leukoplakia, and Kaposi's sarcoma are the most common oral manifestations, but there are other important lesions as well. They include severe necrotizing periodontitis, bacterial and viral infections, lymphomas, and carcinomas. The various oral lesions seen in patients with the acquired immunodeficiency syndrome are reviewed and managements are discussed.

Oral manifestations of AIDS: a study of 84 patients.

Early diagnosis of AIDS is vital in providing appropriate referral for medical care and counseling. Subtle intraoral signs and symptoms identified by the dental practitioner can aid in the diagnosis of the disease. Because the role of the practitioner in detection and treatment of AIDS patients is becoming greater, signs found in 84 patients are described.

Hemodynamic changes during isoflurane anesthesia.

Isoflurane is known to produce slight tachycardia in humans. This study examined the effects of isoflurane on cardiovascular parameters in dogs. Four groups, with six dogs per group, were anesthetized with isoflurane. Prior to isoflurane administration, a femoral artery catheter was inserted. Group 1 was anesthetized with isoflurane alone. Group 2 was pretreated with fentanyl prior to administration of isoflurane. Group 3, anesthetized with isoflurane alone, had a Swan-Ganz catheter introduced through the external jugular vein. Group 4 was pre-treated with fentanyl prior to administration of isoflurane, and had a Swan-Ganz catheter. Physiologic parameters were recorded at 15-min intervals as isoflurane was reduced from 3.5% to 1.5% by 0.5% increments. Heart rate increased while blood pressure decreased during induction (8.5 min) in Group 1 and then returned to control values. In Group 2, heart rate declined with no changes in blood pressure over all isoflurane concentrations. The induction time (time from initiation of the anesthetic until intubation was achieved) was 2 min. In Group 3, the heart rate increased and the blood pressure decreased, with an induction time of 10 min. Cardiac output and pulmonary artery pressure varied inversely to the isoflurane concentration. In Group 4, heart rate decreased with a minimal decrease in blood pressure, and an induction time of 3.5 min. Cardiac output and pulmonary artery pressure varied inversely to the isoflurane concentration. A fifth group of 6 dogs was monitored for heart rate only, while a mask was placed over their noses to simulate the procedure for the administration of an anesthetic. The heart rate increased similar to that of the dogs in Groups 1 and 3, but the tachycardia was abolished with the administration of fentanyl. Increased heart rate could not be directly attributed to isoflurane but was probably due to catecholamines released during induction. Fentanyl blocked this effect, resulting in a decrease in heart rate.

Comparison of single-dose ibuprofen lysine, acetylsalicylic acid, and placebo for moderate-to-severe postoperative dental pain.

In a single-dose, double-blind, parallel-group, single-site study, ibuprofen lysine 200 mg (IBL 200) was compared with acetylsalicylic acid 500 mg (ASA 500) and placebo in 183 patients with moderate-to-severe postoperative dental pain. The relative onset of analgesic response, duration and degree of analgesia, and safety were assessed over a 6-hour postdose period. Analgesic efficacy was assessed by patient self-rating of pain intensity, pain relief, time to meaningful pain relief, global evaluation, and requirement for additional analgesic medication; both IBL 200 and ASA 500 were significantly more effective than placebo. IBL 200 also had a significantly faster onset of action, greater peak and overall analgesic effect, and longer duration of analgesia than ASA 500. All treatments were generally well tolerated.
