Abstract: Extensive animal testing and 30 years of human experience have established the general safety of DEET when applied episodically to skin or bedclothes. Local and systemic toxic and allergic reactions to DEET have been observed in man. Three weeks prior to admission, for the purpose of self-medication, a 30 year old man began daily applications of the insect repellant, DEET followed by a 1-2 hour period in a light-bulb heated box. Sedation and incoherence were noted for short periods following each application session. Aggressiveness and psychotic ideation led to hospital admission where he displayed psychomotor hyperactivity, rapid and pressured speech, tangentiality, flight of ideas, and grandiose delusions. Treatment was begun with haloperidol. Clinical improvement was complete within 6 days, atypical for classic endogenous mania. Drug and metabolites were identified in the urine more than 2 weeks after the last drug application.

Abstract: We treated a case of congenital membranous stenosis of the esophagus successfully by transendoscopic incision. We discuss various types of true congenital esophageal stenosis and their treatment, to distinguish these rare anomalies from the more frequently encountered acquired variety.

Abstract: A rare case of arteriovenous fistula between an internal mammary artery and a pulmonary artery is presented. The clinical history of recurrent bronchitis and dyspnoea during exercise, the presence of right parasternal murmur with normal heart size and normal blood gases justified the execution of an arteriovenous thoracic angiography which revealed the presence of a cirsoid aneurysm supplied by the internal and external mammary arteries. Diagnostic investigation and surgical indication in patients with the rare fistulous communication between the internal mammary artery and the systemic or pulmonary circulation are analysed.
