Abstract: A retrospective study was undertaken to determine whether the Denver Developmental Screening Test (DDST) language sector is a sensitive screen of speech and language development. Seventy-one children between 18 and 66 months of age with suspected developmental problems were referred to screening clinics conducted by a child evaluation team. Each child was screened using the DDST (revised) and another screening measure of speech and language development. Statistically significant differences were found between the DDST language sector and the speech-language screening in identification of expressive language and articulation problems. No significant difference was found with receptive language. The DDST failed to identify more than one half of the children with expressive language and/or articulation problems. These results demonstrate that the DDST may fail to identify children with speech and language impairment. Professionals involved in developmental screening need to be advised of alternative speech and language screening measures.

Abstract: Information obtained for all persons with the acquired immunodeficiency syndrome (AIDS) reported to the Centers for Disease Control, Atlanta, includes a question about employment in a health care or clinical laboratory setting. As of May 1, 1986, a total of 922 (5.5%) of 16,748 adults with AIDS reported employment in such settings. Ninety-five percent of these health care workers belonged to recognized high-risk groups for AIDS; the proportion with "no identified risk" has not increased with time. All AIDS patients (including health care workers) who do not belong to high-risk groups are referred for further investigation. Of 88 health care workers initially reported with no identified risk, ten were from countries where heterosexual transmission is believed to play a major role; additional information was unobtainable or incomplete for 17 individuals. Of 61 persons on whom interviews or other follow-up information was obtained, 44 (73%) were reclassified. Specific occupational exposures that could be implicated as the source of human immunodeficiency virus infection were not identified for any health care workers with AIDS. A review of surveillance data supports other studies indicating that the risk of human immunodeficiency virus transmission in the occupational setting is low.

Acquired Immunodeficiency Syndrome

question:
Abstract: This article presents a protocol for the examination of the shoulder complex. The examination is divided into subjective and objective components. A primary focus of this article is on the functional portion of the objective examination and its interpretation. The functional examination consists of active and passive range-of-motion tests, accessory mobility tests, resisted tests, and palpation. This approach enables the examiner to classify movement disorders of the shoulder complex into dysfunctions of the noncontractile tissues and of the contractile tissues. Factors that enable the examiner to determine the severity of a pathological condition or to identify stages of the healing process are discussed. This information will assist the physical therapist in establishing treatment goals and in selecting appropriate strategies of therapeutic intervention.
