A study of facially expressed emotions as a function of age, exposure time, and sex in children.
Facial expressions and body language constitute a major component of communication in the human population. There are no studies in the dental literature that have examined children's ability to recognize facial expressions. The purpose of this study was to determine children's accuracy and latency to respond to facial expressions (photographs) as a function of age and sex. Sixty children were recruited randomly and placed into three groups according to their age (3, 6, and 9 years) with 20 children per group. They were shown photographs of three different emotions (happiness, anger, and sadness) expressed by actors at three different exposure times (0.2, 0.5, and 1.0 sec), tachistoscopically. The children's responses (accuracy and latency) were recorded. The results indicated that three year olds were significantly less accurate and took longer to respond than the older children. Factors that may have influenced the results and clinical implications are discussed.

Modes of transmission of cholera in a newly infected population on an atoll: implications for control measures.
To determine the modes of transmission in a cholera epidemic in a newly infected population on an atoll, two studies were conducted, in which persons with cholera were individually matched, by age and sex, with neighbourhood controls. Among the first recognised cases, cholera was associated with frequent (daily or weekly) consumption of raw lagoon fish that had been salted and partially dried. Vibrio cholerae was isolated from the lagoon, which was contaminated by human wastes. During the declining phase of the epidemic, cholera was associated with consumption of raw clams, salt-fish, sardines, and other fish from the lagoon. When seafood from enclosed bodies of faecally contaminated water is frequently eaten raw, imported V. cholerae can become established and can be extremely difficult to eradicate.

Cholera in the Gilbert Island. I. Epidemiological features.
An explosive epidemic of cholera due to Vibrio cholerae, biotype El Tor, serotype Inaba, was centered on the coral atoll of Tarawa, Gilbert Islands. This outbreak was a unique experience in the South and Central Pacific region. The principal mode of spread during the peak of the outbreak was probably through contamination of the main water supply. Tarawa lagoon water and shellfish were found to be contaminated with V. cholerae and ingestion of raw fish and shellfish from the lagoon also served as a source of transmission. This outbreak raises the concern of Rother outbreaks of cholera occuring on remote and poorly equipped Pacific islands where the environmental circumstances are conducive to cholera spread.

Cholera in the Gilbert Islands. II. Clinical and laboratory findings.
An epidemic of cholera due to Vibrio cholerae biotype El Tor occurred in 1977 on Tarawa in the Gilbert Islands. No cholera epidemic had occurred there previously and special problems were encountered in both the diagnosis and clinical management. The clinical features of the 585 hospital admissions on Tarawa during the first 64 days of the epidemic were recorded. Eight hospital deaths occurred in this period. A marked increase in cholera among malnourished Gilbertese children was noted. Simplified regimes for management were devised for the circumstances including schemes for oral and intravenous rehydration. Coconut water was used extensively in oral rehydration. Paramedical personnel were used effectively during the epidemic. Prophylactic tetracycline was used in household contacts of patients and was effective in reducing subsequent illness.
