Chile has approximately 600 psychiatrists for its 15 million people. Although in the capital city, Santiago, the provision (per capita) is twice as high as in the rest of the territory, it is possible to see over the past decade a progressive increase in the number of these specialists in the other main cities. There are no more than 50 child psychiatrists and several cities have no local resource in this sub-speciality.

The paper describes the current provision of psychiatric services in Algeria – in particular, in-patient and out-patient facilities, child psychiatry and human resources. Education, training, associations and research in the field of mental health are also briefly presented. The challenges that must dealt with to improve psychiatric care and to comply with international standards are listed, by way of conclusion.

The Kingdom of Bahrain is an archipelago of 33 islands, located in the Arabian Gulf, covering 2400 km2. The main island, Manama, is the nation's capital. The total population stands at 742 562, 62.3% of whom are local Bahrainis and the remaining 37.7% expatriates (Central Statistics Organisation Directorate, 1991). Bahrain first entered the historical stage around 3000 BC, and for almost 2000 years was the centre of the old Dilmun civilisation (Bibby, 1969). Dilmun was perceived as a sacred land by the Sumerians and Babylonians; it was a burial ground for their dead, and Bahrain has over 100 000 burial mounds each containing 200-250 bodies. In the old Babylonian epic of Gilgamesh, which antedates Homer's Iliad, Dilmun is described as a paradise where the worthy enjoy eternal life (Clarke, 1981).

For over a thousand years, the Hippocratic system of medicine prevailed in Europe. It went into oblivion during the Dark Ages, when there was a reversion to the demoniacal theories of mental illness. Hippocrates’ works survived, however, in the library at Alexandria, where they were translated into Arabic. These and other classical works were retranslated into Latin and Greek from the 12th century on, ushering in the Renaissance.

Romania is now in a period of transition from communism to democracy. Geographically, Romania, like other Eastern European countries, is on the border between the Western world and the Middle East and Asia; until December 1989 it was behind the ‘Iron Curtain’.

Malaysia is a tropical country in the heart of South East Asia, at the crossroads of the ancient east–west sea trade routes. Although independent from British colonial rule only in 1957, it has a recorded history dating back to at least the first century CE, when the region was already the source of valuable mineral and forest produce that found markets in China, India and further west.

Portugal is in the south-west of Europe; its territory includes the Azores and Madeira islands, giving it an area of 91 900 km2. The total resident population of Portugal was 10 579 000 in 2006. The population density was 115 per km2. The birth rate has been declining, from 20.0 per 1000 population in 1970 to 10.4 in 2004. Life expectancy at birth in 2006 was 75 for males and 82 years for females. Healthy life expectancy at birth in 2003 was 67 and 72 years, respectively. The infant mortality rate decreased from 10.8 per 1000 in 1991 to 3.5 per 1000 in 2005. The median age of the population has been steadily rising.

Afghanistan's historic strategic position between the great civilisations of India, Persia and Central Asia has made it from the very beginning both a crossroads for trade and cultural exchange and an almost continuous battlefield. In the years since the Soviet invasion in 1979 the country has become the stage of an ongoing complex humanitarian emergency. The period of Soviet occupation was characterised by massive human rights violations. The Soviet army and its allies were involved in indiscriminate bombardments and targeted executions, while the mujahedeen were involved in guerrilla warfare. The USSR was forced to withdraw in 1989 and the remnants of Afghanistan's communist regime were defeated in 1992.

Austria covers an area of some 84000 km2 and has a population of 8.1 million. According to World Bank criteria, Austria is a high-income country. The overall health budget represents 8% of gross domestic product (World Health Organization, 2005). The state of Austria is divided into nine federal provinces, which have significant legislative rights, including in healthcare provision.

The People's Republic of Bangladesh is located in South Asia. The total land area of Bangladesh is 147570 km2. Its total population in 2001 was about 123 million. The population growth rate is 1.47%; of the total population, 75% live in rural areas and 25% in urban areas (Bangladesh Bureau of Statistics, 2000).

The Kingdom of Belgium is a high-income country in northern Europe with an approximate area of 33 000 km2 and a population of 10.5 million. The proportion of the population under the age of 15 years is 17% and the proportion of the population above the age of 60 years is 22%. Life expectancy at birth is 75.2 years for males and 81.5 years for females. As a founding member of what is now the European Union, it hosts the headquarters of the European Commission and the European Parliament, as well as other major organisations, including NATO.

Brunei Darussalam occupies a sliver of land on the northwest coast of the island of Borneo with a geographical area of just 5765 km2 (Government of Brunei, 2004). It is divided into the four districts: Brunei-Muara, Temburong, Tutong and Belait. Two-thirds of the land is covered by lush tropical rainforest and the climate is perpetually warm and humid. It is ruled by Sultan Hassan Al-Bolkiah, the head of a dynasty which has governed Brunei for 650 years.

Cambodia is a low-income country in south-east Asia. It covers an area of 181 035 km2 and has a population of 14.5 million, of whom 42% are less than 15 years old. Life expectancy is 56.8 years and 36% of the population live on less than US$0.50 per day. Cambodia experienced a brutal civil war and genocide in the 1970s under the Khmer Rouge regime, during which approximately 1.7 million Cambodians were killed (Chandler, 1999) and the social and medical infrastructure was almost completely destroyed. No mental health services existed throughout the conflict and subsequent Vietnamese occupation, despite the incalculable impact of the Khmer Rouge regime on Cambodians' mental health. The current political situation is more stable, although there remain concerns about human rights abuses (Khan, 2005).

Ethiopia, in the Horn of Africa, is one of the ancient independent nations of the world and has a rich diversity of peoples and cultures. The country covers 1.1 million km2 (Central Statistical Authority, 2000a). It has a population of about 70 million people (Central Statistical Authority, 2002), 80 different ethnic groups and some 200 dialects. Ethiopia is the second most populous nation in sub-Saharan Africa, after Nigeria (Hailemariam & Kloos, 1993). Forty-eight per cent of the population are under 15 years of age and over 80% live in rural areas (Central Statistical Authority, 1995). Islam and Christianity are the main religions.

Germany has an approximate area of 357 000 km2. Its population is 82.526 million. The life expectancy at birth is 75.6 years for men and 81.6 years for women (World Health Organization, 2005). The proportion of gross domestic product allocated to the health budget is 10.8%. The per capita total expenditure on health is $2820 (international dollars here and below) and the per capita government expenditure on health is $2113 (World Health Organization, 2005). A major factor in recent German history was reunification, which had a pronounced effect on the German healthcare system.

India is a low-income country that is characterised by huge diversity within and between its 35 states and union territories. For example, the infant mortality rate (per 1000 live births) ranges from a low of 16.3 in Kerala to a high of 86.7 in Uttar Pradesh, over a fivefold difference (International Institute for Population Sciences & ORC Macro, 2001). This considerable variation is evident in virtually every aspect of human development in India, and any summary figures are likely to be unrepresentative of most parts of the country. Within the scope of this short article, this important limitation of averages must be recognised at the outset.

The Islamic Republic of Iran is located in the Middle East between the Caspian Sea and the Persian Gulf. Iran's total land area is 1 648 000 km2. Its total population in 2003 was about 68 920 000 (UNICEF, 2003). The population growth rate is 1.41%. Of the total population, 60.4% live in urban and 39.6% in rural areas (Yasamy et al, 2001).

Ireland is the third largest island in Europe and the twentieth largest island in the world, with an area of 86 576 km2; it has a total population of slightly under 6 million. It lies to the north-west of continental Europe and to the west of Great Britain. The Republic of Ireland covers five-sixths of the island; Northern Ireland, which is part of the United Kingdom, is in the north-east. Twenty-six of the 32 counties are in the Republic of Ireland, which has a population of 4.2 million, and its capital is Dublin. The other six counties are in Northern Ireland, which has a population of 1.75 million, and its capital is Belfast. In 1973 both parts of Ireland joined the European Economic Community. This article looks at psychiatry in the Republic of Ireland.

The intense historical relationship linking Jamaica and Britain to 300 years of the transatlantic slave trade and 200 years of colonialism has left 2.7 million souls living in Jamaica, 80% of African origin, 15% of mixed Creole background and 5% of Asian Indian, Chinese and European ancestry. With a per capita gross domestic product of US$4104 in 2007, one-third of the population is impoverished, the majority struggling for economic survival. The prevailing religion is Protestant, although the presence of African retentions such as Obeah and Pocomania are still widely and profoundly experienced, and the powerful Rastafarian movement emerged as a countercultural religious force after 1930. The paradox and contradictions of five centuries of Jamaican resistance to slavery and colonial oppression have spawned a tiny, resilient, creative, multicultural island people, who have achieved a worldwide philosophical, political and religious impact, phenomenal sporting prowess, astonishing musical and performing creativity, and a criminal underworld that has stunned by its propensity for violence.

Jordan, one of the most recently established countries in the Middle East, was part of the Ottoman Empire. It was declared a political entity known as Transjordan under the mandate of the British government in 1923, until it gained independence and was declared a Kingdom in 1946. In 1950, Transjordan and the West Bank were united and assumed the current name of the Hashemite Kingdom of Jordan. The next major change for the Kingdom came in 1967, when the occupation of the West Bank and Gaza Strip by Israeli forces caused a massive influx of migrants to the East Bank.
