[Occupational disability during pregnancy and lactation]. / Incapacidad laboral durante el embarazo y la lactancia.

Historically, women have been known for their role as housewives and were held responsible for children's education. This has changed throughout the years, and they have modified their role in our society. Nowadays, in developed countries, 50% of the working population is represented by women of reproductive age. An important number of these women end up pregnant, and most of them are willing to keep theirjobs after delivery. This is the main reason why pregnancy should not compromise their employment or economic stability. Several international treaties have been signed to defend women, improve their health and reduce child mortality. Even when most countries have developed measures to protect and defend maternity, there is still, a strong difference comparing legislations in this matter, between developed and non-developed countries like Mexico. This is why it is essential to get to know and analyze the main legal dispositions and regulations about maternity issues and protection. We must be aware of the differences in legislation between Mexico and other countries that might influence our own country secondary to sociocultural, commercial and financial exchange. There have been clear and evident improvements related to women's health and maternity matters in the past 15 years. These include longer periods of rest after delivery and making the employer responsible for financing maternity leave.

[Chronic pelvic pain and cervical endometriosis after a subtotal hysterectomy]. / Dolor pélvico crónico y endometriosis cervical después de histerectomía subtotal.

The ectopic location of endometrial glands and stroma may cause the formation of a tumor known as endometrioma. It almost always occurs in the ovary, and due to its characteristic appearance has been called "chocolate cyst". Cervical localization of this disease is extremely rare, and when it occurs, tends to be an exocervical and/or endocervical injury, as a result of cervical procedures. We communicate the case of a patient with cystic endometriosis in the cervix after a subtotal abdominal hysterectomy, performed by obstetric hemorrhage. Even though there have been reports about cases of cervical endometriosis, most of them have been reported as superficial cervical endometriosis and as a discovery after a total hysterectomy or cervical biopsy, in some cases even with original diagnosis ofAGUS (atypical glandular cells of undetermined significance). We concluded that in this case, instrumented uterine curettage and subtotal hysterectomy by obstetric indication are a possible origin of cervical endometriosis, due to "seeding" endometrial tissue during the curettage in a friable cervix.
