[Profile dipper/non-dipper in patient with severe preeclampsia, eclampsia and HELLP syndrome during pregnancy and puerperium].

Background: Blood pressure (BP) has a circadian rhythm, decreases at night and increases in the morning (dipper), have been observed in patients with impaired in this profile, increased at night and lower in the morning (no dipper) have increased cardiovascular risk. Preeclampsia-eclampsia complicates about 7% of pregnancies, preeclampsia is known to reverse the normal circadian cycle of the BP.

Objective: To determine the profile dipper/non-dipper in patients with severe preeclampsia, eclampsia and HELLP syndrome patients in Intensive Care and Obstetrics Hospital Juárez of México.

[Primary cervical cancer screening].

Cervico-uterine cancer screening with cytology decrease incidence by more than 50%. The cause of this cancer is the human papilloma virus high risk, and requires a sensitive test to provide sufficient sensitivity and specificity for early detection and greater interval period when the results are negative. The test of the human papilloma virus high risk, is effective and safe because of its excellent sensitivity, negative predictive value and optimal reproducibility, especially when combined with liquid-based cytology or biomarkers with viral load, with higher sensitivity and specificity, by reducing false positives for the detection of cervical intraepithelial neoplasia grade 2 or greater injury, with excellent clinical benefits to cervical cancer screening and related infection of human papilloma virus diseases, is currently the best test for early detection infection of human papillomavirus and the risk of carcinogenesis.

Increased serum levels of inflammatory mediators and low frequency of regulatory T cells in the peripheral blood of preeclamptic Mexican women.

Regulatory T cells (T(regs); CD4+CD25(high)Foxp3+) are critical in maintaining immune tolerance during pregnancy and uterine vascularization. In this study, we show that, in Mexican women with different preeclamptic severity levels, the number of T(regs) and the subset of CD4+CD25(high)Foxp3+ are decreased compared with those of normotensive pregnant women (NP). Moreover, a systemic inflammatory state is a pivotal feature in the pathogenesis of this disorder and could be related to hypertension and endothelial dysfunction.

[Giant cystic lymphangioma breast. Report of a case with 20-year follow-up and review of the literature].

Background: Lymphangiomas are congenital malformations or acquired (secondary to trauma, infection or neoplasia) in the mammary gland, are extremely rare. These lesions tend to infiltrate surrounding tissues and malignant degeneration is extremely rare. Clinically manifests as benign masses, slow growing; diagnosed clinically and by imaging studies.

[Serum hormones that regulate the reproductive axis in men with testicular germ cell cancer and its impact on fertility].

Background: Epidemiological studies treat testicular germ cancer as a single disease, the behavior of the two histological types of cancer; seminoma and nonseminoma have differences in reproductive hormone secretion and impair fertility differently.

Objective: To demonstrate that the serum concentration of pituitary hormones involved in fertility and spermatogenesis in the affected male is different in the two histological types.

Methods: Were determined by radioimmunoassay or inmunoradiometric assay, luteinizing hormone, follicle stimulating hormone, total testosterone, prolactin, estradiol, human chorionic gonadotropin and alpha fetoprotein in 37 patients with germ cell cancer (15 seminoma and 22 nonseminoma) and 35 controls.

[Clinic characteristics of patients with trophoblastic gestational disease complicate with hypertension].

Background: The molar pregnancy is complicated with hypertension before 20 weeks, divided into complete mole and partial mole, and in diploid and triploid hydatidiform mola depending on the fetal chromosomes.

Objective: To determine clinical and laboratory characteristics of patients with hydatidiform mole with and without hypertension, and choriocarcinoma, correlate serum chorionic gonadotropin (hCG) and hypertension.

Material And Methods: We reviewed 55 cases with histopathologically proven mole, separately analyzed clinical, laboratory and hCG.

[The religious aspects of maternal mortality at the time of the Aztecs. Cihuateteo: dead women at first birth].

Women who die during pregnancy or childbirth, the Aztec goddess regarded with the same value that was given to the warriors who died on the battlefield, accompanied the sun during its journey through the land, but were also feared and regarded as witches who could fly and cause damage and disease to children, could occupy bodies and produce paralysis, at the funeral the relatives of the Cihuateteo should take care of the woman's body because there was a possibility that parts of soldiers stealing him to gain courage in battle. The governing Cihuateteo magical occupations of women.

[Fertility and testicular function in a patient with germ cell extragonadal tumor. A report of a case].

Males are affected from primary extragonadal germ cell tumors with a frequency of 2 to 5%. There is a high incidence of infertility of more than 60% and most of the cases have azoospermia due to testicular damage. The hormonal profile of these patients shows normal luteinizing hormone, normal follicle stimulating hormone and normal testosterone and estradiol.

[Epidemiological analysis of infertility in a Mexican population].

Background: Infertility is defined as the failure to conceive after a year of sexual life without a method of birth control. Most studies indicate that 15% of all couples will experience primary or secondary infertility in some moment of their reproductive life.

Objective: To gain knowledge of general characteristics from patients with infertility in our environment (social, clinical, diagnostic and therapeutic) that attended the Reproductive Biology Department of Hospital Juárez de Mexico.

[Craniopharyngioma and its impact upon human reproduction: analysis of 15 cases at the Hospital Juarez de Mexico].

Background: Craniopharyngiomas are intracranial tumors of non-glial origin derived from cellular remnants of the Rathke's pouch. Their frequency is 1-3% of intracranial tumors and 13% of suprasellar neoplasms. Histologically, it is a benign lesion, albeit clinically severe with a high index of relapse and sequelae upon the reproductive function.

[Heterosexual precocious puberty due to arrhenoblastoma. Postsurgical spontaneous pregnancy].

It is presented the case of a female with heterosexual precocious puberty associated to hyperandrogenism and virilization due to arrhenoblastoma, who became pregnant after surgery. Clinical study: a 14-year-old female initiated at age 6 years with premature pubarche and telarche. By age 11, the patient only had one menstrual period along with virilization.

[Epidemiologic assessment of erectile function in a selected mexican population].

Unlabelled: We determined the incidence, epidemiology and type of erectile dysfunction, as well as risk factors related to erectile function in a Mexican population.

Material And Methods: 452 surveys were applied in direct form, integrated by 38 questions with open answers, dichotomics and multiple to men that accompanied patients that requested medical attention in our clinic and to workers of the Hospital Juárez de México, 18 years or older, with active sexual life, that knew how to read and write. An analytic, prospective and transverse study was performed; obtaining the incidence, frequency of presentation (organic or psychological) of erectile dysfunction and the odds ratio of risk factors observed in the study.

[Polycystic ovarian disease: clinical and biochemical expression].

Unlabelled: The policystic ovary (PO) results from a systemic hormonal dysfunction, characterized by hyperandrogenemia, insulin resistance and anovulation.

Objective: Assessment was made of clinical and biochemical features of patients with PO.

Material And Methods: A retrospective analysis of 211 clinical of charts of patients with ultrasonographic diagnosis of PO seen at the Hospital Juárez de México from 1996 to 2000 was performed.

[Frequency of altered male factor in an infertility clinic].

Unlabelled: Infertility is the incapacity of a couple to conceive after a year of regular sexual life without using a method for family planning. The infertility state is dependent on the female factor as well as masculine factor; an altered masculine factor is designated when any cause or causes of infertility reside in the male. The masculine factor as a cause of infertility is present in 40 to 50% of cases hence the importance of an integral evaluation of male alterations and its fertility.
