Résumé
Introducción: Los delirios de embarazo como síntomas de distintos cuadros psicóticos hansido presentados usualmente en oposición a la naturaleza histérica y psicosomática de laPseudociesis, aunque diversos autores han advertido cierta intersección semiológica entreAmbos fenómenos. Método: Presentamos cuatro casos de pacientes psicóticas que presen-taron delirios de embarazo y revisamos y discutimos la bibliografía pertinente. Resultados: Constatamos la presencia de algunos síntomas compartidos entre psicosis con delirios de embarazo y pseudociesis, aunque sin desmedro de la respectiva diferenciación no sológicaentre los dos fenómenos; existe cierta confusión en los aspectos conceptuales y terminológicos que no contribuye a deslindarlos de forma precisa. Conclusión: Se plantea una visiónamplia y holística para el estudio de la pseudociesis y los delirios de embarazo, que podríanser más frecuentes en realidades como la latinoamericana
Introduction: Pregnancy delusions have usually been considered as symptoms of psychotic disorders in opposition to the hysterical and psychosomatic nature of pseudocyesis, though several authors have described some semiologic intersection between the two phenomena. Method: Introduction of four cases of patients with pregnancy delusions as well as review and discussion of relevant bibliography. Results: In fact, there are symptoms shared by pregnancy delusions psychosis and pseu- docyesis, without detriment of nosological differentiation between the two phenomena. There is certain confusion regarding con- ceptual and terminological issues that does not contribute to mark precise boundaries. Conclusion: A comprehensive and holistic approach for the study of pseudocyesis and pregnancy delusion is proposed. Maybe, these disorders are more frequently observed in Latin America

The decidua of pseudopregnant rats and of those effected by high dosage of luteinizing hormone-releasing hormone analogue (LH-RH-A) were studied histologically.After inducement of pseudopregnancy, 29 Wistar virgin rats were divided into experimental and control groups. The experimental group was injected with 200?g. of LH-RH-A subcutaneously daily for four days, while to the control group, physiological saline was injected instead. Both experimental and control animals were killed on the 9th, 11th and 13th day of pseudopregnancy.The uteri were fixed with appropriate fixatives and paraffin sections were processed with HE, phloxine-tartrazine, Foots and aldehyde fuchsin staihing methods.On the 9th day decidua of the control rats are well developed with many endometrial granulated cells, while in the decidua of the experimental group, the decidual cells become pyknotic, and the granulated cells are barely seen. The results suggest that a high dosage of LH-RH-A advances the necrosis of decidua of the pseudopregnant rats.
Résumé
29 virgin female Wistar rats were divided into experimental and control groupson the 5th day of pseudopregnancy.The experimental animals were injected with200 ?g.of LH-RH-A subcutaneously daily in 5th-8th day,while in the controlgroup physiological saline was used instead.Both experimental and control animalswere killed on 9th,11th,13th days of pseudopregnancy.Histochemical techniques were applied to cryostat sections to show the activityof the following enzymes:SDH,LDH,NE,~5△A-3?-HSD,G6Pase,TPPase,AlPand AcP;PAS,Oil red O,and gallocyanin-chromalum staining methods were usedto show carbohydrates,fats and RNA respectively.The above enzymatic reactions of the decidual cells of the experimental animalswere negative,while those of the stromal cells were positive on 9th day.Incomparison,the results of the decidua of the control group on 13th day are verysimilar to the decidua of the experimental group on the 9th day.The resultssuggest that a high dosage of LH-RH-A only advances degeneration of thedecidua.
