As part of a prospective study of acute bacterial meningitis in children, we studied for five years the hearing of 185 infants and children who had acute bacterial meningitis when they were more than one month of age. Nineteen (10.3 per cent) of the patients had persistent bilateral or unilateral sensorineural hearing loss. The incidence of hearing loss as determined by electric-response audiometry and conventional tests was 31 per cent with Streptococcus pneumoniae, 10.5 per cent with Neisseria meningitidis, and 6 per cent with Hemophilus influenzae infections. Transient conductive hearing impairment was found in 16 per cent of the sample, but in no case was there apparent improvement in a sensorineural deficit over time. The site of disease resulting in impaired hearing cannot be stated with certainty, but involvement of the inner ear or auditory nerve was suspected. The number of days of illness (symptoms) before hospitalization and institution of antibacterial treatment was not correlated with the development of sensorineural deafness.

After bacterial meningitis only children with permanent neurologic deficits are at high risk for epilepsy. Those with normal examinations after the acute illness have an excellent change of escaping serious neurologic sequelae, including epilepsy.

Case control studies are a reasonably rapid and inexpensive method of developing causal hypotheses concerning the role of early environment on the development of psychiatric pathology. The current study tested an interview designed to assess early home environment on a group of patients with alcoholism or depression, on a control group free of psychiatric disorder, and on close-in-age siblings in each group. Findings demonstrated substantial agreement, suggesting that interviews requiring recall of childhood environment may be reasonably valid; patient status did not appear to influence agreement or, presumably, validity.

The increasing number of mothers of young children in the work force and the resultant escalated use of child-care facilities has had a marked effect on the epidemiology of infectious diseases in young children. Children attending child care are at high risk for respiratory and gastrointestinal tract illnesses. The high prevalence of infectious diseases in the child-care setting is accompanied by high usage of antibiotics, which in turn has resulted in spread of antibiotic-resistant organisms. The infectious disease standards of the American Public Health Association/American Academy of Pediatrics guidelines were developed to prevent and limit transmission of infectious diseases in the child-care setting. Adherence to these standards is essential but will not completely eliminate the increased risk of infectious diseases in child-care settings. New challenges need to be addressed to assure that optimal health promotion and disease prevention is practiced in child-care settings. We approach the 21st century with a vast amount of medical knowledge, molecular technology, highly effective vaccines, and powerful antimicrobial agents. However, at the same time we face many unsolved serious problems, such as preventing or controlling the emergence and spread of antibiotic-resistant organisms that adversely affect our ability to treat infectious diseases. Further research is needed concerning the relations between child care, the use of antibiotics, and transmission of antibiotic-resistant organisms in order to design and implement the most effective strategies for preventing or controlling antibiotic resistance. The potential risk for transmission of HIV in the child-care setting also needs to be recognized, and procedures to prevent transmission of blood-borne pathogens need to be followed. Monitoring compliance with national standards for child-care facilities, dissemination of information concerning infectious diseases and use of antibiotics, and development and use of new vaccines are strategies which should be used to help protect the health of children in child-care environments.
