The authors give an annotated list of venomous Invertebrates occurring off Tunisian seas. They point out the action of their venom, the injuries about man, and different therapeutic and prophylactic methods. They conclude that the Cnidaria are the most abundant and most dangerous.
The authors present some eatable benthic Invertebrates like Muricidae and chiefly Mytilidae which could become poisonous under the action of biological et physical and chemical factors of the environment. The symptoms caused by poisonings due to ingestion of contaminated shells are described and therapeutic and prophylactic methods are proposed.

This series of patients was gathered to assess the use of last and slow titration dosage of venlafaxine in in-patients with major depression and to evaluate the action onset. An observational open study was performed in 3 centers in 18 in-patients. Nine patients were included in fast titration dosage group (FT) and 9 in slow titration dosage group (ST). As results, it was found that the FT group showed faster improvement than the ST group in HAM-D score. This improvement was sustained to the final visit, with a lower score in the FT group (6.75) than the ST group (10.67). MADRS scores up to the 15th visit were similar; however, the score was lower in the ST group on the 20th visit. Improvement was sustained to the final visit, the FT group score being lower (6.50) than the ST group score (14). CGI - i mprovement and CGI-seve rity scores we re similar to the above mentioned results. The most common events in both groups were considered mild. The data of these patients show faster response to antidepressant therapy with faster titration dosage, with maintenance of the molecule's tolerability profile.

An evaluation was made of the influence of different psychiatric co-morbidities on the symptoms of the disorder popularly known as "ataque de nervios" (nervous breakdown) among the US Hispanic population. Using a self-completed instrument designed specially for both traditional nervous breakdown and for panic symptoms, and structured or semi-structured psychiatric interviews for Axis I disorders, and evaluation was made of Hispanic subjects who sought treatment for anxiety in a clinic (n = 156). This study centered on 102 subjects who presented symptoms of "nervous breakdown" and comorbidity with panic disorder, other anxiety disorders, or affective disorder. Variations in co-morbidity with "nervous breakdown" enabled the identification of different patterns of "nervous breakdown" presenting symptoms. Individuals with "nervous breakdown" and panic disorder characteristically expressed a greater sense of asphyxiation, fear of dying, and growing fear (panic-like) during their breakdowns. Subjects with "nervous breakdown" and affective disorder had a greater sensation of anger and more tendency toward screaming and aggressive behavior such as breaking things during the breakdown (emotional anger). Finally, subjects with "nervous breakdown" and co-morbidity with another anxiety disorder had fewer "paniclike" or "emotional anger" symptoms. These findings suggest that: a) the widely used term "nervous breakdown" is a popular label for different patterns of loss of emotional control; b) the type of loss of emotional control is influenced by the associated psychiatric disorder; and c) the symptoms characteristics of the "nervous breakdown" can be useful clinical markers for associated psychiatric disorders. Future research is needed to determine whether the known Hispanic entity "ataque de nervios" is simply a popular description for different aspects of well-known psychiatric disorders, or if it reflects specific demographic, environmental, personality and/or clinical characteristics of the population.
