[Role of uric acid in preeclampsia-eclampsia].

Uric acid is a terminal metabolite of the degradation of nucleotides, which increases their blood levels in patients with preeclampsia-eclampsia, increasing its synthesis by damage and death of trophoblastic cells in proliferation and decreased urinary excretion due a lower glomerular filtration rate and increased absorption in the proximal tubule. Hyperuricemia (> 4.5 mg/dL) is the first biomarker of the clinical chemistry considered as an early evidence of disease (< or = 20 weeks gestation).

[Perinatal complications in patients with chronic renal failure].

Background: Pregnant patients with chronic renal insufficiency (CRI) have a high risk of perinatal complications and deterioration of renal filtration (RF).

Objective: To report perinatal complications and changes of RF according to disease severity.

Material And Method: Cross-sectional study including 28 pregnant patients grouped into three categories of CRI according to initial creatinine (Cr): mild CRI < 1.

[Correlation index amylase-creatinine clearance to endogenous creatinine clearance in severe preeclampsia].

Introduction: Tubular lesion may cause acute renal insufficiency in pregnant patients with severe preeclampsia.

Objective: To describe the correlation between the amylase/creatinine clearance ratio and endogenous creatinine depuration in pregnant patients with severe preeclampsia.

Material And Method: Transversal study (pilot study) twenty eight women with pregnancies of 20 to 40 weeks complicated by severe preeclampsia were studied.

[Control of blood pressure mean and its correlation with renal function in patients with severe preeclampsia treated with three oral antihypertensive agents].

Background: In severe preeclampsia, the lack of blood pressure average is a factor for adverse renal function.

Objective: To describe the control of blood pressure mean and its correlation with the endogenous creatinine clearance in severe preeclampsia treated with three oral antihypertensive agents

Patients And Methods: cross-sectional study on 123 pregnant women with severe preeclampsia, treated with 500 mg every 8 h methyldopa, hydralazine 50 mg every 6 h, or 100 mg of metoprolol every 12 hours from admission to the unit intensive care to the care delivery. At time of delivery were compared blood pressure average, endogenous creatinine clearance and the correlation between two of the 123 patients were divided into two groups with matching blood pressure treatment goal of < or = 95 mmHg half: group A, < or = 95 mmHg (25 cases, 20.

[TNF-alpha, C-reactive protein and serum adiponectin modified in infertile patients with insulin resistance].

Background: Women's reproductive potential is closely related to nutritional status. Some of the molecules that participate in ovarian regulation are produced in the adipose tissue, and therefore their production is associated with adiposity.

Objective: To determine serum leptin, adiponectin, C-reactive protein, interleukin-6, and tumor necrosis factor alpha in infertile women with or without insulin resistance; and to associate these molecules with adiposity.

[Diagnostic and frequency of fetal heart disease by echocardiography in pregnancies with high-risk factors].

Background: Fetal heart diseases are increasingly frequent. These are part of birth defects and, therefore, appear in early phases of the gestation. Diagnosis or early detection of functional and structural abnormalities of the heart allows to the obstetrician and the pediatric cardiologist to plan, in a timely manner, the treatment and prenatal and postnatal monitoring with the purpose of preventing complications.

[Active management of the premature membrane rupture in pregnancies of 34 to 37 weeks].

Background: Premature rupture of membranes is considered an obstetrical emergency since it has been associated with an increment of sepsis and maternal-fetal morbidity. For this reason, controversy exists among conservative and active management for the obstetrical resolution.

Objective: To determine if active management of premature rupture of membranes in pregnancy of 34 to 37 weeks diminishes the cesarean section incidence and the maternal-fetal morbidity.

[Therapeutic assessment of emergency cerclage. Analysis of a cases series].

Background: Cervical incompetence is the incapacity of cervix to retain a pregnancy until term or until feasibility of the fetus. Patients present cervical enlargement without pain or contractions, vaginal strange sensation and membranes protrusion through most minimum degrees of enlargement. The cervical incompetence management can be rest in bed or cerclage.

Spontaneous pregnancy in a woman with premature ovarian failure: a case report.

Background: Women with premature ovarian failure often receive hormonal replacement therapy as part of the management strategy. However, it is very unusual for patients to become pregnant while on hormonal therapy.

Case: A 33-year-old woman with a history of infertility and secondary amenorrhea was diagnosed with premature ovarian failure.

[Hormonal replacement therapy and breast cancer. A case-control study].

Aims: Breast cancer is the second more frequently neoplasia in the woman and the first cause of mortality after 35 years old. It is considered a multifactorial illness, since is influenced for genetic, dietary and endocrine factors. Among these, hormonal replacement therapy (HRT) have been assigned benefits effect, as well as risks to increase the breast cancer incidence, because presence of estrogens receptor in the neoplasia cells makes think that the estrogens and other sexual hormones constitute a factor promoter of this cancer.

[Sacropexy with abdominal fascia in treatment of vaginal prolapse vault of menopausal women].

Introduction: Vaginal vault prolapsed is a rare complication, with a frequency from 0.2 to 1% after hysterectomy, which is presented due to a bad surgical technique in fixation of the vault suspension elements, as well others factors as the multiparity, menopause, chronic lungs disease, obesity, smoking and weak physical activity. There are many techniques reported to correct this pelvic disease, although the conventional sacropexy has been established for abdominal way, where the diversity of materials of fixation is varied, including natural material as the abdominal fascia and aponeurosis of muscle rectos.
