Intravenous Diets-Peaston MEDIBALIJOURNAL balance for water. The results in six patients were compared with those obtained during intragastric feeding of the same patients. The intragastric diet of milk powder and glucose maintained metabolic balance except for a negative chloride balance. The urinary total nitrogen, ammonia, and aminoacids were similar on the two diets, but urea excretion was reduced on the intravenous diet, suggesting a decrease in protein catabolism.The investigation was suggested by Professor A. Wilson Although bromide poisoning was described by Huette (1850), it was Wuth (1927) who drew attention to its high incidence in psychiatric hospital wards. The "bromide hazard" was well recognized in the 1930s (Diethelm, 1930 ;Wagner and Bunbury, 1930;Barbour et al., 1936), when vast quantities of bromides were prescribed. Today, however, when their use has been largely replaced by barbiturates, phenothiazines, and other tranquillizers, it seems likely that bromide intoxication is not considered promptly enough in the differential diagnosis of obscure neuropsychiatric problems.
Case 1A 59-year-old woman had been in poor health for many years. Her main complaints were of constipation and fatigue, which were so extreme that she seldom went out and spent much of her day resting on a sofa. At times she was confused, her speech slurred, and her memory poor. In June 1965 she slipped and fractured the neck of her femur. Her post-operative condition gave cause for alarm. She was drowsy, disorientated, and incontinent. She was emaciated ; her tongue was dry and furred. She had bilateral ptosis, constricted pupils, extreme muscular weakness, and depressed tendon reflexes. There were no localizing signs in the central nervous system, and biochemical tests showed no evidence of renal, hepatic, or other metabolic disorder. It was then learned that she had for many years been taking an " innocuous sleeping mixture " prescribed originally for her husband in 1939. Each night she took at least three tablespoonfuls, containing in all 30 minims (1.5 ml.) of tincture of morphine and 60 gr. (3.9 g.) of ammonium bromide. The serum bromide level was found to be 380 mg./ 100 ml. Her mental and physical condition improved gradually but strikingly on withdrawal of the bromide mixture and the administration of ammonium chloride and mersalyl.
Case 3A 59-year-old man was admitted to hospital in May 1965 with a six-months history of progressive mental deterioration and a twomonths history of dragging his right foot. A week before admission he became paranoid and violent before lapsing into a semicoma. He was found at home, in bed, dehydrated, too weak to move, and surrounded by broken furniture. He was dysarthric and his pupils were constricted. Tendon reflexes were diminished in both legs but increased in the right arm, with an equivocal right plantar response.On admission to a general hospital medical ward, examination revealed sordes in the mouth and an acneiform rash on the chest.There was nominal dysphasia as well as dys...
