In this paper, we use a computable general equilibrium model to simulate the effects of drought and a decrease in agricultural productivity caused by climate change in Guatemala. A reduction in agricultural productivity would mean a considerable drop in crop and livestock production, and the resulting higher prices and lower household income would mean a significant reduction in the consumption of agricultural goods and food. The most negative effects of a drought would be concentrated in agriculture, given its intensive use of water. Because agricultural production is essential to ensuring food availability, these results suggest that Guatemala needs a proper water-distribution regulatory framework.

Mental health research funding priorities in high-income countries must balance longer-term investment in identifying neurobiological mechanisms of disease with shorter-term funding of novel prevention and treatment strategies to alleviate the current burden of mental illness. Prioritising one area of science over others risks reduced returns on the entire scientific portfolio.

Worldwide, patients with common mental disorders, such as depression and anxiety, have a tendency to present first to primary care exhibiting idiopathic physical symptoms. Typically, these symptoms consist of pain and other physical complaints that remain medically unexplained. While in the past, traditional psychopathology emphasized the relevance of somatic presentations for disorders, such as depression, in the last few decades, the “somatic component” has been neglected in the assessment and treatment of psychiatric patients. Medical specialties have come up with a variety of “fashionable” labels to characterize these patients and the new psychiatric nomenclatures, such as the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, attempt to classify these patients into a separate “somatoform disorders” category. These efforts fall short, and revisionists are asking altogether for the elimination of “somatoform disorders” from future nomenclatures.

This review emphasizes the importance of idiopathic physical symptoms to the clinical phenomenology of many psychiatric disorders, offers suggestions to the diagnostic conundrum, and provides some hints for the proper assessment and management of patients with these common syndromes.

To test further the highly successful outcomes of a controlled study of in-home behavioural family management (BFM) for schizophrenic patients, a clinic-based version of this intervention was compared with customary care alone for 41 schizophrenic patients in a Veterans Administration (VA) mental health clinic. Monthly Brief Psychiatric Rating Scale (BPRS) ratings, conducted by clinic psychiatrists who were ‘blind’ to the patients' assignment, revealed that 3 (14%) patients who received behavioural family management as well as customary care, as compared with 11 (55%) patients who received customary care alone, had symptomatic exacerbations during the first year of treatment.

‘Hypochondria’, ‘hypochondriasis’, and ‘somatisation’ are terms long used to characterise individuals who display unrelenting somatic symptoms that cannot be medically explained. A psychiatric aetiology for such phenomena is often assumed on the basis of potential psychological gain, the presence of ‘stressors’, the co-existence of unexplained somatic symptom and symptoms of depression or anxiety, or merely the absence of a medical explanation.
