A new case of AIDS-associated, small noncleaved cell (Burkitt's) lymphoma that presented as an orbital mass is described. Extraocular muscle involvement was documented by computed tomography and confirmed by orbital biopsy. Extensive abdominal involvement was subsequently diagnosed and this caused the patient's death only 15 days after the initial consultation and orbital biopsy. A literature review discloses only eight previous case reports of AIDS-associated non-Hodgkin's lymphoma (NHL) involving the orbit: two cases of Burkitt's type and six cases of large cell immunoblastic type. Three additional cases of orbital NHL can be found among larger series of AIDS cases. Affected patients are uniformly young adult males with a history of homosexuality and/or IV drug abuse. Variations in clinical presentation are discussed. Although the morphology of the histopathologic specimen in our case was consistent with a high-grade, small noncleaved cell NHL, flow cytometry revealed an atypical immunophenotype for Burkitt's lymphoma in that CD20 and immunoglobulin light chain antigens were not expressed. Morphologic classification and immunophenotypic characteristics of AIDS-associated NHLs are discussed.

Morton's neuroma: a microscopic evaluation.

Microscopic evaluation of the interdigital neuroma is described in 24 nerves which were evaluated at six cross-section areas for size of the nerve and width of the perineural along with the fascicle diameter and the size and number of blood vessels inside each fascicle. A relationship was noted between the level of the distal edge of the intermetatarsal ligament. Cross-section that was taken at that area showed changes distally in nerve diameter, fascicle number and size, blood vessel number and size, and perineural width. These changes are consistent with the interdigital neuroma as an entrapment condition.

Impact of changes in asthma severity on health-related quality of life in pediatric and adult asthma patients: results from the asthma outcomes monitoring system.

The goals of asthma treatment have broadened beyond managing traditional clinical markers of disease severity, and now include a focus on benefits of treatment in terms that are most meaningful to patients. Measurement of both generic and disease-specific health-related quality of life (HQL) is advocated because each provides complementary information about how the condition affects everyday functioning and well-being and whether treatments have their intended effects. The purpose of this study was to determine the impact of changes in asthma severity (defined using NHLBI/NAEPP severity staging) on patient-assessed HQL. Two hundred and thirty-three pediatric asthma patients and 269 adult asthma patients were evaluated in a one-year observational study. Analyses were performed to compare the generic and asthma-specific scores for patients whose asthma severity improved, stayed the same, or worsened over one year. The asthma-specific scales are sensitive to changes in disease severity. Of the generic scales, those tapping areas of physical health are more affected than the mental/emotional scales. This confirms that HQL measures are responsive to changes in asthma severity. They complement traditional clinical markers used to evaluate changes in a patient's disease state and thus give the physician another useful tool in following the clinical progress of the child with asthma.
