Natural history of HIV-associated salivary gland disease.
To describe the natural history of HIV-associated salivary gland disease, which is characterized by enlarged major salivary glands and/or xerostomia in HIV-infected persons, we assessed 22 patients at an initial and follow-up examinations (median span of examinations, 15 months). Sixteen patients (73%) had bilateral parotid gland enlargement, 17 had symptoms of dry mouth, and 11 had both conditions. Parotid gland enlargement remained unchanged in 10 patients, it progressed in 2, and it regressed in 4 during treatment with zidovudine or steroids. Those patients with parotid gland enlargement had a significantly lower mean stimulated parotid flow rate (0.27 ml/min/per gland) than a control group of HIV+ persons without salivary gland disease (0.48 ml/min/per gland) (p less than 0.05), whereas the mean unstimulated whole salivary flow rates did not did not differ significantly between the two groups. The mean salivary flow rate of the study group did not change during the observation period. When HIV-associated salivary gland disease was diagnosed, 5 patients (23%) had AIDS, and at follow-up 10 (46%) had AIDS. Seven of these had Kaposi's sarcoma. The mean peripheral blood CD4 cell count was 280 and 225 per mm3 at the initial and follow-up examinations, respectively. The corresponding CD8 counts were 1138 and 900. The pathogenesis of HIV-associated salivary gland disease may include hyperplasia of intra-parotid lymphoid tissue. Because HIV-associated salivary gland disease can clinically resemble Sjögren's syndrome, the differential diagnosis of bilateral parotid enlargement should include HIV infection.

Unusual oral presentation of non-Hodgkin's lymphoma in association with HIV infection.
In 4.4% of human immunodeficiency virus-associated non-Hodgkin's lymphoma the presenting lesion is seen in the mouth. Often the lesion may clinically resemble a less sinister process, and a definitive diagnosis of lymphoma may be delayed. We describe three unusual cases of non-Hodgkin's lymphoma, appearing intraorally in association with other oral lesions, in HIV-positive homosexual men. The three patients reported here were all diagnosed as having diffuse, large-cell malignant non-Hodgkin's lymphoma. We performed Epstein-Barr virus DNA in-situ hybridization on our cases and Epstein-Barr virus DNA sequences were not seen. We review the pertinent literature and stress the importance of including non-Hodgkin's lymphoma in the differential diagnosis of oral lesions in patients at risk of HIV infection.

Sialochemistry in human immunodeficiency virus associated salivary gland disease.
Human immunodeficiency virus (HIV) associated salivary gland disease is defined as the presence of enlargement of one or more major salivary glands and/or diminished salivary function in an HIV infected individual. It has a number of similarities to, as well as differences from, Sjögren's syndrome (SS). We studied the sialochemistry of stimulated parotid saliva of 11 patients with HIV associated salivary gland disease and bilateral parotid gland enlargement, and compared these findings with those of 15 HIV negative controls, 13 HIV positive individuals with no salivary gland involvement and 18 individuals with SS. The patients with HIV associated salivary gland disease had a significant decrease in the level of salivary protein, with increases in salivary IgA, lysozyme and albumin compared to the HIV negative controls. There were no changes in concentration of electrolytes. The sialochemistry among the patients with HIV associated salivary gland disease was unrelated to the degree of immune suppression and did not change over a 6 month period. The observed changes were similar to those of SS but less pronounced. The similar clinical, histologic and sialochemical features of HIV associated salivary gland disease and SS suggest that these conditions share common pathogenetic mechanisms, which may be modified in the former by the HIV infection.

Oral Kaposi's sarcoma in a woman as a first indication of HIV infection.
Although Kaposi's sarcoma has been well described in homosexual men at risk for infection with the human immunodeficiency virus, there have been fewer reports of KS in women, and most of these have been in women who became infected with HIV through intravenous drug use. This report describes a woman who had no history of intravenous drug use in whom intraoral KS and hairy leukoplakia were the first indication of her infection with HIV.

Oral candidiasis in HIV infection: pseudomembranous and erythematous candidiasis show similar rates of progression to AIDS.
Candidiasis is the most common oral fungal infection seen in association with HIV infection. It may present in a number of clinical forms, including pseudomembranous and erythematous candidiasis. To determine whether erythematous candidiasis, like the pseudomembranous form, is predictive of the development of AIDS, we reviewed the records of 169 HIV-seropositive patients seen at clinic of the Oral AIDS Center, University of California, San Francisco who were diagnosed with pseudomembranous or erythematous (or both) forms of oral candidiasis at their first examination. Kaplan-Meier analysis showed a rapid rate of progression to AIDS (median, 25 months) and to death (median, 43.8 months) in all three groups. We conclude that erythematous candidiasis is as serious a prognostic indicator as pseudomembranous candidiasis. Because the erythematous form is more difficult to recognize and hence is underdiagnosed, efforts should be made to teach non-dental clinicians who care for HIV-infected patients to diagnose and treat this lesion.

Peripheral argon laser iridectomy in narrow-angle glaucoma.
Gas argon laser peripheral iridectomy was attempted as an alternative to surgical peripheral iridectomy in the treatment of acute angle-closure glaucoma and the prophylactic treatment of fellow eyes. Success was achieved in eyes with a blue iris if sufficient energy was given to achieve a permanent red reflex. Reasons for failure in eyes with a heavily pigmented iris are discussed. The procedure must be greatly improved before surgical peripheral iridectomy is superseded as the treatment of choice.
