Clinical evaluation and surgical treatment of hemangiomata

We report on the histologic and anatomopathologic aspects of cutaneous hemangiomas, stressing the involutive and noninvolutive aspects of these malformations. We analyze its clinical evolution, approaching the propedeutic and therapeutic methods, and present a detailed commentary on the conservative methodology of a series of 473 consecutive patients, encompassing a follow-up of 1 to 18 years.     

Antiinflammatory agents protect opossum esophagus during radiotherapy

Eighteen opossums received 2250 rad⁶⁰Co to the entire esophagus and lower esophageal sphincter. Animals received treatment with 600 mg aspirin, 25 mg/kg hydrocortisone, or saline before irradiation and twice daily for 1 week after irradiation. At 10 days postirradiation, animals were evaluated for signs of acute esophagitis by esophagoscopy and barium esophagram. Each animal was then killed and the esophagus removed and evaluated histologically. Animals treated with either aspirin or hydrocortisone had significantly milder esophagitis than control irradiated animals.Supported by IN-121 from the American Cancer Society.     

Factitial aplastic anemia

A 29-year-old married nurse with pancytopenia was discovered to be surreptitiously ingesting alkylating agents. Despite her life-threatening behavior, there was no evidence that she was psychotic, depressed, or cognitively impaired. Psychological testing was indicative of a sociopathic personality. The patient and her behavior elicited considerable affect and controversy among members of her health team. It is hypothesized that the patient's behavior resulted from longstanding low self-esteem. The production of a dramatic illness gratified dependency needs and fooling physicians gave her a sense of power.
