This review summarizes the discovery of oncogenes which are the activated versions of normal cellular protooncogenes which serve essential functions in the control of cell proliferation and differentiation. Their activation disrupts the normal control mechanism which rests on the subtle balance between their effects and those of anti-oncogenes or tumor suppressor genes. One may reasonably hope that defining a complete profile of alterations of both these types of essential genes in the tumor or in the clinically healthy individual will be invaluable to assess prognosis or genetic predisposition, respectively.

[Digestive insufficiency and artificial feeding. Theoretical and practical aspects (author's transl)].

The relatively new concept of digestive insufficiency was born as a result of prolonged artificial nutrition. Digestive insufficiency may be of organic, functional or mixed nature; its medical and surgical causes are numerous. Artificial nutrition has become a major therapeutic adjuvant in all types of digestive insufficiency. By acting as a substitute for the intestinal function, artificial nutrition permits better tolerance of specific treatments thanks to the nutritional rehabilitation and intestinal rest which it provides for as long as the patients' malnutrition and digestive lesions make it necessary.

[Case study--relationship between prevalence of shyness, social phobia and avoidant personality in male sexual disorders].

UNLABELLED: Social phobia, avoidant personality disorder and shyness are very akin disorders, despite the fact that the first two are mental disorders, whereas the third is found mainly in lay or psychological literature. The relationship between these disorders and male sexual disorders can only be hypothesized from clinical studies and psychopathological theories. Social phobia, avoidant personality disorder, and shyness, share a probable indirect responsibility in sexual disorders because they impair the ability of subjects to meet partners. There are only a few direct studies of the negative impact of shyness on sexual behavior. OBJECTIVE: The objective of this study was to compare males with sexual disorders to non-sexual disorder males on diagnosis of social phobia, avoidant personality disorder and shyness. METHODS: We conducted a case-control study comparing a group of male patients seeking care for sexual disorders (n = 87) and a control group of male subjects without sexual disorder (n = 87), regarding the diagnosis of social phobia, avoidant personality disorder and shyness. Diagnoses were appreciated with a structured diagnostic interview (CIDI for the diagnosis of social phobia) or a list of criteria (DSM IV criteria for avoidant personality disorder) and through standardized scales (Fear Questionnaire, CBSHY, Cottraux male sexual problems questionnaire). Severity of shyness was evaluated through visual analog scales. RESULTS: We found strong significant statistical differences between cases and controls regarding the percentage in each group of social phobia, avoidant personality disorder and shyness. For shyness, the mean score at CBSHY was 16.2 (+/- 12.63) for the cases and 6.07 (+/- 6.67) for the controls (p < 0.0001), whereas the percentage of cases with a score of > 19.5 was 41.4% vs 6.9% for the controls (p < 0.001); 27.6% of the cases had a CIDI diagnosis of social phobia vs 8% of the controls (p < 0.001); 31% of the cases implemented DSM IV criteria for the diagnosis of avoidant personality disorder vs 6.9% of the cases (p < 0.001). CONCLUSION: Our results are in favor of one or several factors in common between social phobia, avoidant personality disorder and shyness, which would be strongly related to male sexual disorders.
