Four elderly women with chronic oral ulcerations are described. The lesions are chronic, erosive, or ulcerative; occur on the gingival, buccal, or lingual mucosa; and may occur in the form of desquamative gingivitis. The histopathologic findings are nondiagnostic. The disease is refractory to local and systemic corticosteroids, but treatment with hydroxychloroquine may be effective. Both in vivo binding to the oral mucosa and skin of a stratified epithelium-specific antinuclear antibody and high titers of these antibodies in serum are markers of this disease, which we refer to as chronic ulcerative stomatitis associated with stratified epithelium-specific antinuclear antibody.

Chlorhexidine's structural characteristics give it potent antimicrobial activity, effectiveness at low concentrations, substantivity that prolongs its therapeutic effect in the oral environment, minimal resorption from the gastrointestinal tract, and the ability to reduce plaque. The use of this agent for oral stomatitis in neoplasia patients has recently been studied. Treatment-associated oral soft tissue inflammation and ulceration were significantly reduced by chlorhexidine in patients undergoing intensive chemotherapy. Reductions in total streptococci and yeast counts were also observed. When used in conjunction with systemic antifungal agents, such as nystatin or clotrimazole, a significantly decreased incidence of clinical oral candidiasis and Candida septicemia was observed. In contrast, in two studies in which high-dose head and neck radiation therapy was applied, there was no reduction in stomatitis. Oral gram-negative bacilli have been shown to increase in high-dose chemotherapy patients who are taking chlorhexidine during the treatment period (3 wk to 2 mo). However, no increase in systemic gram-negative infections or other adverse negative medical consequences were observed. This agent appears to be of therapeutic benefit in reduction of dental plaque, gingivitis, and stomatitis in the high-risk chemotherapy population when used in conjunction with other topical and systemic antimicrobial agents as prophylaxis. Although no toxic or serious adverse effects of chlorhexidine rinse have been observed in the short-term studies to date, the effects of longer-term chlorhexidine administration should be evaluated.

From January 1988-September 1989, dental practitioners performed a comprehensive oral examination on 83 HIV positive patients at the Department of Infectious Diseases, University Clinic of Internal Medicine in Kinshasa, Zaire for a study on prevalence and clinical aspects of oral lesions associated with HIV infection. Women comprised 55.5% of these AIDS patients. They all had oral lesions: 94% fungal, 33% bacterial, 23% viral, 14% unknown origin, and 12% neoplasms. The majority of these oral lesions developed in 31-40 year olds. Further, the 21-30 year olds were more likely to have bacterial infections, especially aggressive periodontitis. Fungal infections occurred most often on the lips, palate, and tongue, while viral infections occurred mainly on the tongue. Kaposi's sarcoma only afflicted the palate. Pseudomembranous candidiasis was the leading fungal infection (32% of all oral lesions) then atrophic (22.8%) and hyperplastic (6%) types. 17% and 16% of all lesions included these bacterial infections: aggressive periodontitis and necrotizing gingivitis respectively. the leading viral infection was hairy leukoplakia (14%) followed by leukoplakia (8%), and herpetic stomatitis (4%). The unknown lesions included ulcers (12%) and a swollen salivary gland )2%). 12% of the examined AIDS patients, mostly 31-50 year olds, had oral Kaposi's sarcoma. They also had it on other parts of the body. Since HIV prevalence in Zaire ranges between 3-8%, all dentists should be cognizant of oral manifestations of HIV which may indeed be the 1st clinical indications of HIV. They should refer any patients with such lesions to a health facility with AIDS specialists for diagnosis and care.

Recently, sedative and antiphlogistic treatment is conducted with low energy laser irradiation. The purpose of the this study was to evaluate the effectiveness to decrease of pain just after irradiation by a GaA1As semiconductor laser. The irradiation apparatus was SEMI LASER NANOX (LX-800: G-C. Co.) with the following features: a wave length of (around) 780nm: the laser energy, 30mW; exposure time, 30sec to 180sec/per treatment. Diagnosis of pre- and post-operative sensitivity were classified into the following four grades: Grade 0 no pain. Grade I mild pain. Grade II strong but tolerable pain. Grade III intolerable pain (simultaneous with stimulation). The results were as follows: 1. In the hypersensitivity of dentin, the treatment was not effective with 2 cases of grade III, but with all of grade I, II (35 cases) the pain decreased just after irradiation. 2. It was effective in all cases with pain like periodontitis after root canal filling and pain after extraction of teeth. 3. It was effective in all cases with gingivitis, stomatitis, and gingival ulcers after infiltration anesthesia etc..

The fundamental basis of allergy, particularly in relation to contact allergy, is described, together with the importance and frequency of sensitization to nickel, chromium and cobalt in both the consultant and general population. 139 published cases of allergy to dental restorations containing these metals are reviewed involving 92 female and 47 male patients, 115 of whom recovered when the restorations were removed. The most frequent symptoms were local (99/139), particularly gingivitis and stomatitis, while general or remote symptoms occurred in 33 cases. This probably underestimates the true prevalence of the condition, because a large number of reported cases have not been due to their "current appearance". The influence of the occupational environment of the patient is described with special reference to dental technicians. The persistence of contact allergy to metals for which no desensitization is possible is also emphasised. The discussion includes experimental investigations and an appraisal of other methods of revealing hypersensitivity. Finally, some simple recommendations for prevention are made which are of value to practitioners.

A representative sample of the pet cat population of the United Kingdom was surveyed. Blood samples from 1204 sick and 1007 healthy cats of known breed, age and sex were tested for antibodies to feline immunodeficiency virus (FIV) and feline leukaemia virus (FeLV). The prevalence of FIV was 19 per cent in sick cats and 6 per cent in healthy cats, and the prevalence of FeLV was 18 per cent in sick cats and 5 per cent in healthy cats; both infections were more common in domestic cats than in pedigree cats. Feline immunodeficiency virus was more prevalent in older cats but FeLV was more prevalent in younger cats. There was no difference between the prevalence of FeLV in male and female cats but male cats were more likely to be infected with FIV than female cats. No interaction was demonstrated between FIV and FeLV infections. Of the cats which were in contact with FIV in households with more than one cat, 21 per cent had seroconverted. The prevalence of FeLV viraemia in cats in contact with FeLV was 14 per cent. The clinical signs associated with FIV were pyrexia, gingivitis/stomatitis and respiratory signs, and with FeLV, pyrexia and anaemia. It was concluded that both viruses were significant causes of disease, and that the cats most likely to be infected with FIV were older, free-roaming male cats and for FeLV, younger, free-roaming cats.

Inorganic bismuth salts are poorly soluble in water: solubility is influenced by the acidity of the medium and the presence of certain compounds with (hydr)oxy or sulfhydryl groups. The analysis of bismuth in biological material is not standardised and is subject to large variation; it is difficult to compare data from different studies, and older data should be approached with caution. The normal concentration of bismuth in blood is between 1 and 15 micrograms/L, but absorption from oral preparations produces a significant rise. Distribution of bismuth in the organs is largely independent of the compound administered or the route of administration: the concentration in kidney is always highest and the substance is also retained there for a long time. It is bound to a bismuth-metal binding protein in the kidney, the synthesis of which can be induced by the metal itself. Elimination from the body takes place by the urinary and faecal routes, but the exact proportion contributed by each route is still unknown. Elimination from blood displays multicompartment pharmacokinetics, the shortest half-life described in humans being 3.5 minutes, and the longest 17 to 22 years. A number of toxic effects have been attributed to bismuth compounds in humans: nephropathy, encephalopathy, osteoarthropathy, gingivitis, stomatitis and colitis. Whether hepatitis is a side effect, however, is open to dispute. Each of these adverse effects is associated with certain bismuth compounds. Bismuth encephalopathy occurred in France as an epidemic of toxicity and was associated with the intake of inorganic salts including bismuth subnitrate, subcarbonate and subgallate. In the prodromal phase patients developed problems in walking, standing or writing, deterioration of memory, changes in behaviour, insomnia and muscle cramps, together with several psychiatric symptoms. The manifest phase started abruptly and was characterised by changes in awareness, myoclonia, astasia and/or abasia and dysarthria. Patients recovered spontaneously after discontinuation of bismuth. Intestinal lavage, forced diuresis and haemodialysis have been tried without positive effects on the clinical condition of the patient or on blood bismuth concentration, and the use of dimercaprol as an antidote has produced reports of both positive and negative findings. To confirm the diagnosis of bismuth encephalopathy, it is essential to find elevated bismuth concentrations in blood, plasma, serum or CSF. A safety level of 50 micrograms/L and an alarm level of 100 micrograms/L have been suggested in the past, but no proof is available to support the choice of these levels.(ABSTRACT TRUNCATED AT 400 WORDS)

A new retrovirus was recently discovered in cats affected with an immunodeficiency syndrome (AIDS). The virus shows morphological and biological similarities with the human immunodeficiency virus (HIV), which causes AIDS in human individuals. As the T-lymphocyte is the primary target of the virus, it is termed Feline T-Lymphotropic Lentivirus (FTLV). FTLV is not antigenically related to HIV. Transmission of the virus from animals to human subjects has not been recorded. Cats infected with this virus showed lymphadenopathy, leukopenia, anorexia, chronic stomatitis/gingivitis and other opportunistic forms of infection. Neurological symptoms were also observed. Research is focused on diagnosis, treatment and prevention. Results obtained may contribute to research on AIDS in human subjects.

Since many years ago are known curative effects of propolis on different lesions due, mainly, to more than 30 biologically active elements isolated from it. It is a wordly accepted opinion that propolis is one of the most useful substances elaborated by bees. Despite it, its use in our country is relatively recent. Several investigators, specially in Matanzas, study curative effects of propolis in the field of human and animal medicine. In other countries it has been used in stomalogy, but we have no knowledge about its therapeutical effects in the periodontal disease or its effectiveness in oral ulcers. Therefore, a therapeutical form has been elaborated, which is provisionally called Propolan, for the treatment of two entities: chronic gingivitis and stomatitis of different etiology. The clinical cases supporting effectiveness found with the treatment applied in our setting are presented.

Between the 2 of january and the 31 of december 1985 there was done a study of 215 children in ages between 0-15 years in the Department of Oral Diagnosis of the Ibadan University Hospital, where they were external patients with oral infections/swelling. The male-female proportion was 1.3:1. 42.33% were from 0 to 5. 70.24% belonged to the lowest social group of the community, with a high risk of oral-facial infections. The situation of their oral hygiene didn't reflect their social and economical state, and meant no predisposition to infection. The common infections were alveolar abscess, acute necrotizing ulcerative gingivitis and primary herpetic gingivo-stomatitis. They could be complicated with measles and for nutritive failure. Neoplasms were uncommon. Infections were frequent in jaw; antibiotic therapy and "depridement" were often enough to eliminate them.
