Reducing distress in cancer patients with an orientation program.

The purpose of this study was to test a brief orientation program for reducing anxiety, depressive symptoms, and overall distress in cancer patients at their initial clinic visit. One hundred and fifty consecutively referred patients seen in an oncology outpatient clinic were randomly assigned to an intervention or usual care control group. The intervention group received a clinic tour, general information about clinic operations, and a question and answer session with an oncology counselor. Outcome measures included the State-Trait Anxiety Inventory (STAI), the Brief Profile of Mood States (POMS), the Center for Epidemiologic Studies-Depression (CES-D) Scale, and an oncology clinic questionnaire which were administered at the initial clinic visit and follow-up. There were no statistically significant clinical or demographic differences between groups at initial assessment. At follow-up, the intervention group had lower state anxiety, lower overall distress, and fewer patients reporting depressive symptoms. Patients in the intervention group demonstrated significantly more knowledge about clinic operations and greater satisfaction with care. These data provide evidence that anxiety, distress and depressive symptoms can be reduced with an orientation program. This finding has particular relevance in the early stages of diagnosis where patients may suffer symptoms of anxiety and depression.

The potential role of various species of intermediate hosts of Schistosoma haematobium in Saudi Arabia.

The potential role of 3 species of Bulinus in the transmission of Schistosoma haematobium in Saudi Arabia was assessed on the basis of their susceptibility to experimental infection, their geographical distribution and numbers, and the type of habitats in which they were found. B. truncatus, distributed mainly in the mid- and south-western regions, showed extremely low susceptibility to strains of S. haematobium from Yemen, Egypt and Sudan. The same species from one area in the north-west was refractory to a strain of the parasite from Yemen. In contrast, B. wrighti was very susceptible to infection but is found only in a few habitats far from human settlements, thus probably playing little part in the transmission of the disease. As B. beccarii is highly susceptible to the infection and is distributed widely, this snail is probably the main intermediate host of schistosomiasis in Saudi Arabia.
