Of the laryngeal granulomas, the best prognoses were given by the postintubation ones, whereas the worst were those of undefined cause. Those ascribed to gastroesophageal reflux and vocal abuse have a high resolution rate, although some cases need rescue procedures.

The chondroitin sulfate excreted in the urine of 10 patients with cancer of the head and neck and 27 healthy subjects was analyzed. The disaccharide products formed from chondroitin sulfate excreted by these 10 patients by action of chondroitinase ABC show a significant (P < 0.0001) relative increase of nonsulfated disaccharide (35.6% +/- 5.7%) when compared with the nonsulfated disaccharide (10.0% +/- 0.9%) present in the chondroitin sulfate of 27 healthy subjects. In 6 patients the structure of the excreted compound was analyzed up to 4 months after surgery. After removal of the cancer, the percent amounts of the nonsulfated disaccharide tend to approach the values found for the chondroitin sulfate of healthy subjects. A significant (P < 0.0001) change in the ratio of urinary chondroitin sulfate and heparan sulfate and a decrease in the electrophoretic migration of chondroitin sulfate were also observed. All of the patients with head and neck cancer analyzed so far have shown this structural anomaly of urinary chondroitin sulfate. This assay may be useful in the diagnosis and follow-up of cancer therapy.

We report the case of a 72 year-old man with advanced, stage IV, prostate cancer who underwent osteosynthesis of the cervical spine for nerve root decompression due to metastasis which was causing severe pain in his right upper limb. After three months in the hospital, he developed occlusive thrombosis of the right axillosubclavian vein as a complication of prolonged catheterization of the right subclavian vein for treatment of septicemia secondary to a hospital acquired pneumonia. The patient received thrombolytic therapy with IV streptokinase in the contralateral arm in the following dosage: 250,000 units in 15 minutes followed by 100,000 units per hour during five days. This led to total recanalization of the thrombus, with significant reduction of the arm edema. Twenty-four hours after the end of the thrombolytic therapy, the patient started to complain of dysfagia to solids and liquids and a contrasted esophagogram revealed extensive extrinsic compression of the esophagus due to a probable retroesophageal hematoma. The patient required enteral nutrition via nasoenteral tube during three months after which swallowing returned to normal and a repeat upper GI series confirmed that the hematoma had been reabsorbed, with normal passage of contrast through the esophagus. On late follow-up, the patient did not show evidence of any sequelae of deep venous thrombosis nor any residual dysfagia and is currently in use of elastic stockings and low molecular weight heparin.
