Pitfalls of CT findings in post-therapy testicular carcinoma.
Computed tomography demonstrated fibrotic or necrotic lesions in the retroperitoneum and liver that were indistinguishable from viable tumor in three patients who had undergone therapy for testicular carcinoma. Therefore, residual masses after therapy may not signify viable disease.

Severe pulmonary involvement in mixed connective tissue disease.
Pulmonary involvement in mixed connective tissue disease has been considered a benign manifestation that is easily treated with corticosteroids. We followed 5 patients who had mixed connective tissue disease and severe, rapidly progressive, lung disease. Two types of lung disease were found, interstitial lung disease and pulmonary hypertension. Histologic sections from our patients were compared with sections from patients who had interstitial lung disease and systemic lupus erythematosus or pulmonary hypertension and scleroderma. Although clinical presentations were similar, the immunofluorescent and electron microscopic findings for interstitial lung disease were somewhat different in patients with systemic lupus erythematosus. Histologic findings for pulmonary hypertension appeared different in patients with mixed connective tissue disease and patients with scleroderma. For patients with either type of lung disease, corticosteroid therapy proved inadequate, but nearly cytotoxic therapy may be beneficial.

Percutaneous needle biopsy in abdominal lymphoma.
Percutaneous needle biopsy of lymph nodes and abdominal masses was performed in 48 patients with abdominal lymphoma. A correct diagnosis was obtained in 15 of 28 biopsies performed on lymph nodes and in 17 of 25 abdominal masses or organs. The overall success rate was 64%. No false-positive diagnoses were rendered. No complications related to the procedure were encountered. The value of this technique in the management of selected patients with abdominal lymphoma is detailed.

Primary carcinoma of the male urethra.
Of 27 men with primary urethral carcinoma, 11 had tumors that rose at or anterior to the penoscrotal junction; 16 had tumors arising between the membranous urethra and the penoscrotal junction. Surgery was the only effective definitive therapy, and only palliative methods could be used for half of those patients with posterior tumors. A good prognosis was possible if primary treatment controlled the malignant process, but all patients in whom tumor recurred locally eventually died of their disease.

Fine-needle aspiration biopsy of the liver.
Percutaneous fine-needle aspiration biopsy of focal liver lesions was performed in 36 patients. Of the biopsies, 83% yielded enough cytologic material for a correct diagnosis, without significant complications. The primary indication for the biopsy was to document the presence of malignancy and avoid a diagnostic laparotomy.

Pain assessment from patients with burns and their nurses.
We investigated pain experienced during burn wound debridement. Forty-nine adult patients with burns and 27 nurses submitted 123 pairs of visual analog scale pain ratings for burn wound debridements. While patients' overall visual analog scale pain scores were found to be evenly distributed, worst pain scores yielded a bimodal distribution with groups centered around means of 2.0 (low pain group) and 7.0 (high pain group). Low and high pain groups did not differ in age, sex, or total body surface area burned. Patient and nurse pain ratings were found to be highly correlated. According to one researcher's criteria, 53% of nurse pain ratings were accurate. Accuracy of nurses' ratings was unrelated to nursing experience or educational level. Future strategies are presented for comparing high and low pain groups and increasing nurse pain rating accuracy.
