Homophobia is still a scourge in the modern era. Despite a greater acceptance of sexual variations and same-sex marriage in many countries, homophobia is widely sustained by religious, political and cultural values and beliefs at individual and social level. Most of homophobic attitudes are based on the principle of heteronormativity according to which heterosexuality is the standard for legitimating social and sexual relationships and homosexuality is considered as an abnormal variant. Homophobia may be also recognised at institutional level (state-sponsored homophobia, social homophobia) and supported by laws or religious beliefs. Moreover, internalised homophobia (IH) is defined as the inward direction of societal homophobic behaviours at individual level and refers to the subjective psychological impact of these negative attitudes. In fact, IH is significantly associated with a high prevalence of internalising mental disorders such as depression, anxiety, stress/trauma-related disorders, etc. We believe that a set of immediate actions are needed in order to contrast homophobia and its impact on mental health, in particular political initiatives, educational trainings and scientific research should be promoted with a specific focus on mental health needs of people target of homophobia.

Pollutant agents are exponentially increasing in modern society since industrialization processes and technology are being developed worldwide. Impact of pollution on public health is well known but little has been described on the association between environmental pollutants and mental health. A literature search on PubMed and EMBASE has been conducted and 134 articles published on the issue of pollution and mental health have been included, cited, reviewed, and summarized. Emerging evidences have been collected on association between major environmental pollutants (air pollutants, heavy metals, ionizing radiation [IR], organophosphate pesticides, light pollution, noise pollution, environmental catastrophes) and various mental health disorders including anxiety, mood, and psychotic syndromes. Underlying pathogenesis includes direct and indirect effects of these agents on brain, respectively, due to their biological effect on human Central Nervous System or related to some levels of stress generated by the exposure to the pollutant agents over the time. Most of emerging evidences are still nonconclusive. Further studies should clarify how industrial production, the exploitation of certain resources, the proximity to waste and energy residues, noise, and the change in lifestyles are connected with psychological distress and mental health problems for the affected populations.

Rapid urbanization worldwide is associated to an increase of population in the urban settings and this is leading to new emerging mental health issues. This narrative mini-review is based on a literature search conducted through PubMed and EMBASE. A total of 113 articles published on the issue of urban mental health have been selected, cited, reviewed, and summarized. There are emerging evidences about the association between urbanization and mental health issues. Urbanization affects mental health through social, economic, and environmental factors. It has been shown that common mental syndromes report higher prevalence in the cities. Social disparities, social insecurity, pollution, and the lack of contact with nature are some of recognized factors affecting urban mental health. Further reserach studies and specific guidelines should be encouraged to help policy makers and urban designers to improve mental health and mental health care facilities in the cities; additional strategies to prevent and reduce mental illness in the urban settings should be also adopted globally.

Human beings are social animals, and familial or social relationships can cause a variety of difficulties as well as providing support in our social functioning. The traditional way of looking at mental illness has focused on abnormal thoughts, actions and behaviours in response to internal causes (such as biological factors) as well as external ones such as social determinants and social stressors. We contend that psychiatry is social. Mental illness and interventions in psychiatry should be considered in the framework of social context where patients live and factors they face on a daily basis.

The clinical practice of psychiatry should incorporate a biopsychosocial model of illness, acknowledging both cultural and social influences on the patient's experience. Medical humanities include a number of academic disciplines that complement the clinical practice of psychiatry. The medical profession, including psychiatry, has a social responsibility to study the psychosocial context within which people become ill and have to be treated. Although the biopsychosocial model of illness has strong theoretical foundations, its application in clinical practice is limited. A new approach would be to restructure medical student teaching to include medical humanities in the first year, and to share such education with other professions.
