Laryngeal chondrosarcoma as a late-appearing cause of "idiopathic" vocal cord paralysis.

A case of laryngeal chondrosarcoma is presented as a late-appearing cause of idiopathic vocal cord paralysis. Twelve cases are cited from the literature in which the cause of so-called idiopathic vocal cord paralysis was discovered with long-term followup. The natural history of idiopathic vocal cord paralysis is addressed, and recommendations for patient management are discussed.

Immunizations among hospital personnel.

To minimize the likelihood of transmission of certain infectious diseases within the hospital, the 5 million US health care personnel are becoming a special target group for immunization programs. A review of immunizations conducted by a hospital employee health service demonstrated that 80% of hospital employees are adequately protected against tetanus/diphtheria, and 97% are immune to rubella. In contrast, only 28% of at-risk employees are immunized against hepatitis B and only 2% are immunized against influenza. Vaccination programs for tetanus/diphtheria and rubella, which are supported by appropriate legislation, are more effective than vaccination programs for hepatitis B and influenza, which are not supported by appropriate legislation.

Alcoholism in house staff physicians: an occupational hazard.

Alcohol abuse is a major public health problem among physicians. To assess the extent of alcohol abuse among house staff physicians, the self-administered version of the Michigan Alcoholism Screening Test was mailed to each of the 417 house staff physicians at the Presbyterian Hospital in the City of New York at the Columbia Presbyterian Medical Center. There was a 45% response rate. Of the respondents, 12.7% had scores that indicated either suspicion or presumption of alcoholism. Alcohol abuse among house staff physicians is an occupational hazard that needs to be addressed through preventive and treatment programs.

Preplacement examination of temporary hospital workers.

One hundred ninety-nine temporary hospital employees were given preplacement medical examinations during the New York City hospital strike in 1984. Major findings pertain to susceptibility to communicable disease and to drug abuse. Sixty-three percent of individuals examined were found to be inadequately immunized against diphtheria and tetanus, 41% to be susceptible to rubella, and 12.6% to be tuberculin skin test positive. Three percent had positive urine toxicologies for either cocaine, heroin, or phencyclidine and were subsequently denied employment. Thirteen percent had potentially significant physical findings. One individual was denied employment pending treatment; two individuals with seizure disorders were placed in noncritical areas. Forty-one percent of individuals examined smoked and were eligible for smoking cessation programs.

Preemployment qualitative urine toxicology screening.

Five hundred routine preemployment urine toxicology examinations were performed on prospective hospital employees in 1981. Thirty-three (6.6%) examinations were positive for one or more of either Valium, barbiturates, amphetamines, phencyclidine or opiates. Only 13 (2.6%) were confirmed to be positive. Of those with confirmed positive results, only one applicant was denied employment. Significantly, that case would have been suspected during the clinical preemployment examination. These results indicate that including a routine urine toxicology screen in a preemployment examination may not be cost-effective.

Glycerine injection and crystal formation in the larynx: a negative study.

Glycerine as a vehicle may be injected alone or with Teflon to reposition a lateral lying paralyzed vocal cord. During the study of a particular patient, crystal formation was observed in laryngeal tissues injected with glycerine. It was hypothesized that glycerine metabolized to oxalic acid crystals via the glyoxylic acid pathway. To confirm this proposition, the gluteus muscle of guinea pigs was injected with glycerine, and at weekly intervals submitted for ordinary and polarized light microscopic examination. The formation of crystals after glycerine injection was not found in the guinea pig. Similarly, no foreign material or crystals were found after centrifuging the stored glycerine.
