The neuropeptide alpha-MSH has been proposed to influence learning and memory by increasing visual attention. To test the possibility that MSH selectively affects visual learning, rats were tested in learning tasks in which the cues were either visual or auditory. Maze and bar-press tasks were used. MSH administration increased the rate of learning of the visual tasks, regardless of the task difficulty or the type of response required of the rat. MSH had no effect on the rate of learning of the auditory tasks. These results support the hypothesis that MSH facilitates learning by influencing some aspect of visual information processing.

A trial with fluocinonide in recalcitrant dermatoses.

The effectiveness and safety of fluocinonide 0.05% in a cream base (FAPG cream: fatty acid propylene glycol) were evaluated in 105 patients with recalcitrant corticosteroid-responsive dermatoses that had failed to respond adequately to at least two weeks' previous treatment with one of 21 other topical corticosteroid preparations. At the end of the three weeks, 66 (71.0%) of the 93 patients who qualified for analysis showed excellent to moderate improvement with fluocinonide. Side effects were rare and of a minor nature. The general effectiveness of fluocinonide is indicated in this single-blind trail in which excellent or moderate results predominated in 8 of the 12 different diagnosis.

Non-Hodgkin's lymphoma of the thyroid gland occurring after treated Hodgkin's lymphoma.

OBJECTIVE: To present a case report of the occurrence of non-Hodgkin's lymphoma in the thyroid gland of a patient who had previously undergone successful treatment of Hodgkin's lymphoma. METHODS: We describe pertinent historical features and current symptoms and laboratory findings in a 62-year-old man who had had successful treatment of Hodgkin's lymphoma 10 years previously and had been free of disease for a decade. We also review the related medical literature on the course of patients after therapy for Hodgkin's lymphoma. RESULTS: Because of a progressively enlarging anterior neck mass, hoarseness, and difficulty with breathing, a patient sought medical attention. Ten years previously, he had undergone irradiation and splenectomy for treatment of Hodgkin's lymphoma. In the current assessment, fine-needle aspiration and open biopsy yielded the diagnosis of non-Hodgkin's lymphoma, for which the patient received irradiation and chemotherapy. Review of the literature pertaining to diseases after treated Hodgkin's lymphoma, including second cancers, failed to identify any such prior reported case. CONCLUSION: Because the clinical profile of our patient was consistent with primary non-Hodgkin's lymphoma of the thyroid gland developing after radiation-treated Hodgkin's lymphoma, we conclude that this represents the first such reported example.

Intermittent gastroesophageal intussusception in a cat with idiopathic megaesophagus.

An adult female domestic shorthair cat was evaluated for chronic upper respiratory disease and vomiting. A diagnosis of idiopathic megaesophagus with intermittent gastroesophageal intussusception (GEI) was made based on radiographic and endoscopic examinations. The GEI was manually reduced by use of a stomach tube during the endoscopic procedure. An incisional gastropexy was performed to prevent recurrence. Gastroesophageal intussusception is a rare condition in cats. In dogs it is usually associated with rapid progression of clinical signs, culminating in death. In this cat, the condition was associated with chronic signs, probably due to the intermittent nature of the GEI.
