Usefulness of SPECT in the early detection of avascular necrosis of the knees.

Single photon emission computerized tomography (SPECT), was performed on a female with an acutely painful knee. She had been on corticosteroids just before the onset of symptoms. Radiographs and planar scintigraphic views of the knees were unremarkable. SPECT images of the knees were instrumental in the diagnosis of avascular necrosis of the knee. The cases illustrates the usefulness of SPECT in the early detection of avascular necrosis of the knees.

Multidirectional instability of the shoulder in the athlete.

Laxity of the inferior glenohumeral ligament is the essential lesion in involuntary multidirectional instability of the shoulder. Most important in the diagnosis, which is difficult to make, is the physical examination. Treatment consists of strengthening the muscles in the direction of the greatest instability. If this fails after a year, surgery is indicated.

Inferior capsular shift for involuntary inferior and multidirectional instability of the shoulder. A preliminary report.

In thirty-six patients (forty shoulders) with involuntary inferior and multidirectional subluxation and dislocation, there had been failure of standard operations or uncertainty regarding diagnosis or treatment. Clinical evaluation of these patients stressed meticulous psychiatric appraisal, conservative treatment, and repeated examination of the shoulder. All patients were treated by an inferior capsular shift, a procedure in which a flap of the capsule reinforced by overlying tendon is shifted to reduce capsular and ligamentous redundancy on all three sides. This technique offers the advantage of correcting multidirectional instability through one incision without damage to the articular surface. One shoulder began subluxating again within seven months after operation, but there have been no other unsatisfactory results to date. Seventeen shoulders were followed for more than two years.

Late hematogenous infection of total joint replacement.

Late deep wound infection secondary to hematogenous spread of bacteria from a distant focus is an infrequent but devastating complication of total joint replacement. Nine patients (ten implants) with documented late hematogenous infection are reported, all of whom demonstrated several characteristic features. The initial operation was free of clinical evidence of infection and a long asymptomatic interval ensued, followed by a definite febrile illness and acute joint pain. The source of the infection often was not recognized until late and prophylactic antibiotics were not given when it was identified. Seven of the ten implants had to be removed. The primary responsibility for the prevention of this devastating complication lies with the surgeon, who must inform each patient of the risk of late hematogenous seeding from infection elsewhere in the body. It is also important to pay special attention to patients who are at particularly high risk, such as those with rheumatoid arthritis or other systemic diseases. A knowledge of the bacterial flora of the various areas of the human body is essential in choosing the appropriate prophylactic antibiotic.

A program to help asthmatic students reach their potential.

Asthma is the most common chronic disease of childhood, affecting 15 percent of Americans under the age of 15. It ranks first among the chronic disease in causing school absenteeism, and it has been linked to lowered academic performance. An educational program for elementary school teachers has been developed to assist the asthmatic student in reaching his or her potential. The program addresses needs expressed by members of the Montgomery, Ala., chapter of Parents of Asthmatic Kids (PAK). These parents voiced concern regarding the inadequate preparation of teachers for dealing with the needs of the asthmatic student. Results of a survey of teachers in local elementary schools confirmed their need for asthma education. The program, consisting of an audiovisual presentation, an informative brochure, and an instructional packet to use with first to sixth graders, is designed to be presented in faculty meetings throughout the school system. To evaluate the effectiveness of the module, a simple test is administered before and after the program. The program has been accepted by the American Lung Association of Alabama and is under consideration by the American Lung Association at the national level.
