Coriocarcinoma no gestacional: reporte de un caso / No gestational choriocarcinoma: case report

Resumen ANTECEDENTES: El coriocarcinoma es una neoplasia maligna del epitelio trofoblástico, agresiva pero susceptible de curación, incluso cuando hay metástasis. Puede ser de origen gestacional o no, el primero aparece después de un embarazo molar o aborto. CASO CLÍNICO: Paciente de 14 años, acudió a Urgencias debido a un cuadro de abdomen agudo, con prueba en orina positiva de embarazo; además, una tumoración en la región anexial derecha. En la laparotomía se encontró una tumoración dependiente del anexo derecho, con la cápsula rota, adherida al colon. Un día después de la intervención quirúrgica (por no contar con recursos en la unidad) se tomó la fracción beta de gonadotropina coriónica. El diagnóstico definitivo se estableció con base en el reporte del estudio histopatológico de la pieza quirúrgica. CONCLUSIÓN: El coriocarcinoma es una neoplasia maligna del epitelio trofoblástico, muy agresiva pero susceptible de curación, incluso cuando se detectan metástasis. La incidencia en México de coriocarcinoma gestacional es de 0.133 por cada 100,000 mujeres, mientras que la incidencia del cariocarcinoma no gestacional se desconoce. Se reporta como un tumor muy raro; por ello el diagnóstico preciso y oportuno es difícil en este tipo de tumores; la presentación más habitual es el abdomen agudo.

Abstract BACKGROUND: Choriocarcinoma is a malignant neoplasm of the trophoblastic epithelium, very aggressive but highly curable, even when there is metastasis. It can be of gestational and non-gestational origin, the first one can develop after a pregnancy, abortion or molar pregnancy; in Mexico it is calculated with an incidence of 0.133 per 100,000 women. While the incidence of non-gestational choriocarcinoma is unknown as it is reported as a very rare tumor. The objective is present the first case reported in our hospital, there are few cases reported in Mexico, it is important to know them in order to identify, diagnose and refer them on time. CLINICAL CASE: A 14-year-old patient who presented to the emergency department with a picture of acute abdomen with pregnancy test in positive urine and tumor in the right adnexal region, laparotomy was performed, finding a tumor dependent on the right annex with a broken capsule attached to the colon, one day after the surgical event (due to lack of resources in the unit) beta fraction of chorionic gonadotropin, the definitive diagnosis was made by the histopathological study of the surgical piece. CONCLUSION: Choriocarcinoma is a malignant neoplasm of the trophoblastic epithelium, very aggressive but highly curable, even when metastases are detected. In Mexico, the incidence of gestational choriocarcinoma is 0.133 per 100,000 women, while the incidence of non-gestational cariocarcinoma is unknown, it is reported as a very rare tumor, which is why accurate and early diagnosis is difficult in this type of tumors. , since the most common presentation is an acute abdomen.

Las ambivalencias de la interrupción voluntaria del embarazo / The ambivalence of voluntary termination of pregnancy Summary

La interrupción voluntaria del embarazo es una opción con la que cuenta la mujer, si una vez embarazada se ve inmersa en alguna causal que le facilite terminar, de manera consciente, la gestación en curso. Si la mujer ejecuta los requisitos para las circunstancias en que se puede solicitar la interrupción voluntaria del embarazo, esta debe contar con la asesoría en opciones de terminación de la gestación; con lo cual se le ratifican sus derechos a la autonomía y la autodeterminación reproductiva. No obstante, también se le debe informar que aun estando inmersa en alguna causal puede optar por continuar con la gestación y asumir la crianza o dar el producto del embarazo en adopción..(AU)

The voluntary interruption of pregnancy is an option with which the woman counts, if once pregnant she is immersed in some cause that facilitates her to finish, in a conscious way, the gestation in progress. If the woman executes the requirements for the circumstances in which the voluntary interruption of the pregnancy can be requested, this one must count on the advising in options of termination of the gestation; with which his rights to autonomy and reproductive self-determination are ratified. However, you should also be informed that even if you are immersed in some cause you can choose to continue with the pregnancy and assume the upbringing or give the product of the pregnancy for adoption..(AU)

Are the Requirements of Propofol Decreased in Early Pregnancy during Anesthetic Induction? / 대한마취과학회지

BACKGROUND: Minimum alveolar concentration (MAC) is decreased during pregnancy, but there are no data regarding the requirements for intravenous agents. Recently only one study showed that the requirement for thiopental in pregnant women of 7-13 weeks' gestation was less than the requirement obtained in nonpregnant women. Thus we wanted to determine whether pregnant patients needed less propofol for hypnosis and anesthesia than nonpregnant patients. METHODS: One hundred nonpregnant women having gynecologic surgery and 100 pregnant women of 5-13 weeks' gestation undergoing elective abortions were recruited. They were randomly allocated 10 groups according to the doses of propofol and each group had 10 patients. During a period of 30 seconds, one of the doses of propofol 1.0, 1.25, 1.5, 1.75, 2.0, 2.25, 2.5, 2.75, 3.0 or 3.25 mg/kg was administered. Two minutes later, patients were asked to open their eyes as a test for hypnosis. Patients who did not open their eyes were given a 10 seconds, 50-Hz, 80-mA transcutaneous tetanic electrical stimulus to the ulnar nerve as a test for anesthesia. Estimates of ED50 and ED95 for hypnosis and anesthesia were obtained by logistic regression. RESULTS: In the pregnant women, the median effective doses (ED50) (95% confidence interval) for hypnosis and anesthesia were 1.25 (1.13-1.35) mg/kg and 2.71 (2.49-3.04) mg/kg, the ED95 (95% CI) were 1.51 (1.16-1.87) mg/kg and 3.04 (2.80-3.58) mg/kg respectively. Whereas in the nonpregnant women, the ED50 for hypnosis and anesthesia were 1.27 (1.39-1.90) mg/kg and 4.12 (3.50-6.01) mg/kg, the ED95 were 1.53 (1.41-1.93) mg/kg and 4.35 (3.66-7.26) mg/kg respectively. CONCLUSIONS: In early pregnant women, the doses of propofol for hypnosis and anesthesia were 1.6% and 34.2% less compared with those in nonpregnant women.
