Glaucoma topical preparations are generally found safe in terms of sterility, though bacterial growth may be found in a small percentage. In most cases, the cause of the loss of sterility could not be determined. However, in two preparations, contamination was related to the noncompliance of the patient who continued using the same preparation longer than instructed. It is imperative to increase the awareness of glaucoma patients to the fact that improper use can lead to eye-drop contamination.
The 15 patients with the highest numbers of assaultive incidents over a one year period in a state mental hospital were identified and information collected regarding a variety of clinical and demographic characteristics. The results showed a group of patients who are relatively young, manifest severe symptomatology that is generally unresponsive to treatment, and have now been hospitalized continuously for greater than four years. The patients experienced the onset of symptoms as teenagers in most cases, showed poor psychosocial adjustment beyond childhood, and had positive family histories for mental illness or alcohol abuse. Patients with psychotic disorders predominated and tended to have positive symptoms rated as severe to very severe on the Global Rating Scale for Psychosis. Patients with nonpsychotic or personality disorders always showed a high frequency of self-injurious behavior in addition to their aggressive behavior toward others. A number of patients had a history of head trauma with EEG abnormalities. This information provides a starting point for subsequent studies examining potential distinctions between this subpopulation of patients and others, the motivation and circumstances of such incidents, and the interaction between the behaviors and their effects on those around them.
Using the criterion of early morning urinary specific gravity (SPGR) of 1.008 or less to define the presence of polyuria, we identified 26 of 72 male (36 percent) and 14 of 31 female (45 percent) institutionalized chronically psychotic patients as polyuric during a comprehensive survey of one of the chronic care units at a State mental hospital. Factors including diagnosis, sex, age, weight, and serum sodium did not distinguish the polyuric from the nonpolyuric patients. For men, administration of lithium was associated with polyuria. Urinary creatinine concentration (UCR) correlated well with SPGR, and UCR may provide an alternate index to separate polyuric from nonpolyuric patients. The clinical implications of our findings are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
