Abstract
We compared the coping strategies of 39 short-sleepers and 33 longer-sleepers to the stresses associated with the October 17, 1989 San Francisco Bay Area earthquake using their responses to the eight scales of the Ways of Coping Questionnaire. Over-all, the short-sleepers scored significantly higher on this questionnaire and in general, the pattern of their responses was consistent with inferences that could be drawn from a 1972 paper by Hartmann, Baekeland, and Zwilling.

Beginning in 1956, major San Francisco Bay area employers were sampled at 10-year intervals for a 30-year period to assess attitudes toward the employment of epileptic workers. In this time, we documented a trend of sustained positive change that appears to validate the efforts of organizations that have focused on raising public awareness of this disorder.

Abstract
While the etiology of nocturnal bruxism is unknown, three major categories of theories have been advanced to explain its cause(s), i.e., local-mechanical theories, psychological theories and systemic/neurophysiological theories. The recent report of a four-fold increase in the incidence of self-reported nocturnal bruxism in college students over the last 23-year period emphasizes the role that psychological variables may play in the development of this disorder and it is suggested that the personality traits which contribute to stress management are primary among these.

Abstract
Speculation and indirect evidence have suggested a relationship between habitual sleep duration and food intake. We tested this hypothesis by asking groups of short- and longer-sleeping students to keep 21-day sleep and food-intake diaries. We found no reliable evidence that sleep habits are linked to any major dietary variables as measured in this study and concluded that the differences between our results and those of an earlier study may reflect differences in the methodologies used.

Abstract
During a 2-year period after the introduction of an intensive chemotherapeutic protocol, alpha-hemolytic streptococci accounted for 75% of all episodes of sepsis among children with acute nonlymphocytic leukemia at our institution. Only one case had occurred in the previous 8 years. Fourteen of 15 episodes of streptococcal sepsis occurred after therapy with either continuous or large dosage intermittent cytosine arabinoside. Eleven episodes occurred at two specific treatment points. Septic episodes were complicated by shock (2 of 15), encephalopathy (2 of 15), pneumonia (3 of 15) and death (1 of 15). Oral mucosal lesions may provide a portal of entry for alpha-hemolytic streptococci. These data suggest that children receiving continuous or large dosage intermittent cytosine arabinoside for treatment of acute nonlymphocytic leukemia may be at increased risk for alpha-hemolytic streptococcal sepsis. Empiric antimicrobial therapy in these children when febrile and neutropenic should include antibiotics effective against alpha-hemolytic streptococci.

Abstract
A cost-benefit analysis of routine active immunization against hepatitis B virus (HBV) for 500 nursing personnel at The Children's Mercy Hospital in Kansas City, Missouri, is described. Based on outcomes of HBV infection, local charges for medical care and wages lost from illness, the authors calculate the average cost per case of HBV infection to be $1,990. Including the current system of postexposure prophylaxis and an annual attack rate of 1 percent the current annual cost of HBV infection in The Children's Mercy Hospital is $12,630. The HBV immunization program would have to continue for 15 years before its cumulative costs ($189,133) were exceeded by those of the current system ($189,450). Therefore routine immunization of nurses would not be cost effective in the near future. If, however, a subset of high-risk employees with a 2 percent attack rate is identified, or the cost of the HBV vaccine series fell from the current $103 to $27, then routine immunization would become cost beneficial within 6 years.

Abstract
Seroprevalence of hepatitis B virus markers was examined in employees participating in patient care at The Children's Mercy Hospital in Kansas City, Missouri. Of 377 workers tested in 1985-86, 36 (9.6%) were seropositive for any marker. Among 285 employees who presumably have only work-related hepatitis B exposure, 14 (4.9%) were seropositive. Age 50 years and older, black race, and education no more than 12 years were associated with seropositivity among workers with work-related exposure. Employees in the clinics, laboratories, emergency room, and operating room had an increased prevalence of hepatitis B markers compared to those in other work locations (8 vs. 2%, p less than 0.05). Traditional risk factors for infection were not predictive of seropositivity. Although the risk of acquiring hepatitis B infection from employment in a children's hospital is low, this study does identify work-related risk factors. Possible reasons for this association are discussed.

Abstract
Twenty-nine intubated pediatric patients were prospectively studied to determine whether nontypable Haemophilus influenzae (NTHI) is associated with the development of nosocomial pneumonia. Throat cultures and tracheal Gram stains, leukocyte counts and cultures were obtained immediately following intubation, then serial studies on tracheal secretions were performed. Median patient age was 13 months. One patient had preexisting lung disease and 14 (48%) had pneumonia when intubated. There were five deaths. NTHI was recovered from the initial throat or tracheal culture in seven patients (24%); none developed a nosocomial lower respiratory tract infection. NTHI was not associated with any of three cases of nosocomial pneumonia. Three of 12 NTHI isolates were beta-lactamase producers. Tracheal leukocyte counts and Gram stains were not predictive of pneumonia, either at the time of intubation or subsequently. We conclude that NTHI in the oropharynx or trachea is not predictive of pneumonia among intubated pediatric patients.

Abstract
A mild hypothermia was produced in female rats during treatment with pyridoxine HCl (Vitamin B6), 100 mg/kg, administered in the drinking water. The hypothermic effect appeared by day 3 and persisted through 15 days of treatment. The reduction in core temperature was greater early in the day, just following the nocturnal period of maximum food and water consumption of the rat. Tail tendon temperatures of control and pyridoxine-treated animals showed no evidence of increased heat loss. Thus the hypothermia appears to reflect decreased heat production. The implications of a reduced metabolic rate for gerontological research are discussed.

As a means of providing psychometric validation of Friedman and Rosenman's (1977) clinical observation that Type A individuals show excessive levels of covert hostility, groups of Type A and Type B students were tested with the Buss-Durkee (1957) Hostility Inventory. Type A students expressed higher levels of hostility than the Type B students. However, this difference was due primarily to the relatively greater level of overt hostility of the Type A group. These groups did not differ in level of covert hostility.

The handedness distribution of a group of 578 gifted elementary school children (I.Q. = 132) was compared to handedness distribution of 391 non-gifted children (I.Q. less than 132), with the result that the gifted group was significantly less right-handed than their non-gifted peers. These data were discussed relative to Bakan's hypothesis that left-handedness results from stressful prenatal and birth conditions. In addition attention was paid to the possibility of a non-linear relationship between intelligence and degree of right-handedness.

In an attempt to clarify the relationship between self-reported birth complications and handedness, the handedness distributions of 181 college students who reported birth complications and 1320 students who reported no complications were compared. The results suggest a clear but modest shift in the birth complications group away from the dextral end of the continuum. However these data did not validate the hypothesis that left-handedness results from birth complications.

Abstract
Recently Leviton and Kilty reported that the birth dates of left-handed girls in elementary school display a seasonal trend which peaks in November. We report here a failure to replicate this finding for 257 male and 323 female college students. Further, we have considered the likelihood that the original finding was due to sampling error rather than speculating that environmental factors associated with the season of birth are implicated in the etiology of left-handedness, as Leviton and Kilty have stated.

Abstract
As a further test of the hypothesis that REM deprivation decreases fear, the behavior of 40 male rats was measured in a Y-maze adapted to test for preference for novelty. Prior to this test, the animals were exposed for 4 days to one of four treatments, i.e., either a dry environment control, a wet environment control, a 2-day REM deprivation period or a 4-day REM deprivation period. During the test both number of grid crossing in the novel and non-novel arms of the Y-maze and three indices of emotionality were recorded. The results were congruent with data we had reported earlier and offered convincing evidence in support of the hypothesis.

Abstract
Using 30 Sprague-Dawley female rats, threshold to pain was measured over the course of recovery from REM sleep deprivation. Relative to the untreated controls and to their own pretreatment thresholds, the REM-deprived animals showed significantly reduced pain thresholds which were still evident 96 hours after the termination of the REM deprivation. Possible implications of these data for research with analgesic drugs were noted.
