Pain relief and palliative care in Hong Kong.

Palliative care started in Hong Kong in 1982. It gradually established an increasingly important role in cancer care. Hong Kong is fortunate because analgesic drugs and expertise from various disciplines and specialties in pain management are readily available.

Personal exposure to nitrogen dioxide and its association with respiratory illness in Hong Kong.

In 1985, 362 primary schoolchildren and their 319 mothers were surveyed in Hong Kong to study the possible relationship of air pollution to respiratory illnesses. Using nitrogen dioxide (NO2) measured by personal samplers as a measure of air pollution, the study aimed to identify the major sources of NO2 in the indoor environment and see whether its increased presence was associated with respiratory symptoms. The levels of NO2 among the mothers was found to increase by 21% if dust exposure was reported from the workplace, 18% if they used such cooking fuels as liquid petroleum gas or kerosene, 11% when kitchens did not have ventilating fans, and 10% when incense was burned at home.

Worldwide epidemiological patterns of lung cancer in nonsmokers.

A review of published reports on lung cancer was done to describe its worldwide epidemiological pattern and to elucidate the contribution of smoking and nonsmoking risk factors in its aetiology. Among lung cancer patients, roughly 98% of males worldwide, and 70-90% of European and American females, reported a history of smoking. Asian women had much lower (6-57%) rates of smoking.
