Heat-tempered composite resin laminate veneers.

Laminate veneers have rapidly become the restoration of choice for the conservative esthetic restoration of anterior teeth. The historical development of the process for veneering teeth is presented, and the significant advancements since the introduction of the concept nearly 60 years ago are highlighted. Heat-tempered composite resin laminate veneers are evaluated, including their advantages and disadvantages relative to bonded porcelain veneers. A new technique for the creation of one-appointment heat-tempered hybrid composite resin laminate veneers is discussed. Recent research into the critical features and properties of heat-tempered composite resin inlays and onlays and laminate veneers is reviewed, as are suggestions for technique improvements based on scientific investigations.

Pneumocystis carinii pneumonia studied by gallium-67 scanning.

The validity and reliability of gallium-67 (Ga-67) scanning for diagnosis and follow-up of Pneumocystis carinii pneumonia (PCP) were assessed in 34 patients thought to have pulmonary complications of acquired immunodeficiency syndrome (AIDS). Overall sensitivity was 94% and specificity 74%. Among patients with normal or equivocal chest radiographs at the time of admission, sensitivity was 86% and specificity 85%. The authors consider Ga-67 scanning a valid and reliable adjunct in the diagnosis of PCP in AIDS patients with respiratory symptoms when the chest radiograph is normal or equivocal.

Lyme disease in northern California.

Lyme disease is a recently described clinical entity with cutaneous, neurologic, articular and cardiac manifestations. Since the original description of the disease in 1977, more than 500 cases have been reported. Although the vast majority of patients have been from the area near Lyme, Connecticut, we have seen four patients from northern California with various aspects of Lyme disease. This diagnosis should be considered in patients who have traveled to tick regions and who have a distinctive skin lesion (erythema chronicum migrans). Clinical and epidemiologic evidence suggests the disease is transmitted by a tick, lxodes dammini in the eastern United States, lxodes pacificus in the West and lxodes ricinus in Europe. The etiologic agent, a new spirochete, may have been recently discovered.

Histocompatibility antigens in progressive systemic sclerosis (scleroderma).

A study was undertaken to determine the distribution of major histocompatibility (HLA) antigens in progressive systemic sclerosis (PSS) (scleroderma). A total of 106 patients with PSS and 208 normal controls were tested for the presence of 18 different HLA antigens by the microcytotoxicity technique. These patients were equally divided between patients with classical diffuse scleroderma (53 patients) and those with the CREST syndrome variant of the disease (53 patients). When the P values were multiplied by 18, to correct for the number of antigens studied, no significant alteration in the frequency of any HLA antigen was found for the entire group of scleroderma patients or for either of the two subpopulations.

Direct oven-tempered hybrid composite-resin laminate veneers.

The difficulty in achieving optimal aesthetics of the single-tooth indirect laminate veneer has prompted the author to develop a direct technique for fabricating oven-tempered hybrid composite resin veneers. These restorations exhibit excellent physical properties, marginal integrity, and aesthetics.
