Thymic carcinoid.

Carcinoid of the thymus is a rare neoplasm. Differentiation from thymoma is important because they have entirely different prognosis. A patient in whom a 19 x 18 x 12 cm carcinoid tumor of the thymus was surgically removed is presented. The tumor metastasized to peritracheal and internal mammary nodes, and invaded the SVC, pleura, lung, and pericardium. This is apparently the largest reported tumor of its kind. Prior to induction of anesthesia cardiopulmonary bypass and rigid bronchoscopy were readily available. Awake intubation was utilized. Even though long-term prognosis is poor, an aggressive surgical approach and adjuvant radiotherapy may achieve extended survival with excellent quality of life. Central aspects of the disease as well as pivotal therapeutic points are discussed.

Cup arthroplasties in teen-agers and children.

Review of cup arthroplasties performed prior to 1970 in sixty hips of fity-one consecutive patients less than twenty years old, with follow-up on fifty-three hips, revealed that fifteen (28%) of the cup arthroplasties were followed by other salvage operations, usually total hip arthroplasty. Of the remaining thirty-eight hips, only twenty-four (63%) were rated satisfactory clinically, although most of the patients considered their cup arthroplasty an improvement over their preoperative status. Patients with bilateral hip disease did very poorly, and results were inconsistent in others. The final range of motion was frequently poor. Results were improved in hips in which acetabular reaming was not required.

Osteomyelitis following puncture wounds of the foot in children.

Review of the laboratory and clinical findings and treatment of eight patients with osteomyelitis of the foot after puncture wounds revealed that: 1) osteomyelitis after puncture wounds is a infrequent but potentially serious complication, with significant morbidity; 2) osteomyelitis is frequently preceded by inadequate primary care for simple puncture wounds, and when treatment is appropriate, osteomyelitis usually can be avoided; 3) P. aeruginosa is the most commonly recovered organism; 4) the clinical presentation is characterized by a lack of systemic toxicity, paucity of laboratory abnormalities, and evidence of a localized infection process and the patient may be asymptomatic for a few days to several months after the injury before presentation of the osteomyelitis; and 5) once the infection has become established, treatment must be aggressive, including surgical debridement.
