OBJECTIVES: To determine the maternal characteristics with statistical probabilities of association with neo natal infection in patients rum premature rupture of membranes (PROM), both at term, as premature. Evaluate the perinatal morbidity and mortality MATERIAL AND METHODS: Retrospective observational study, case-control (infected-no newborn infected) between April 1998 and March 1999, according to protocol established in the Department of Obstetrics Loayza Hospital, entering pregnant with a single fetus, active, without fever and diagnosed with RPM. RESULTS: Of 3985 deliveries, 284 had RPM: 263 were to term and 21 preterm; 8 infants were not assessed (transferred by malformations, four mature, four premature). 259 pregnancies to term 42 infants were infected (16.2%) and 17 premature 11 were infected (64.7%). In term pregnancies, unmarried marital status was statistically significant i...

Objective: To determine the intrauterine growth retardation associated risk factors. Methods and design: Case control study in the obstetric service of Loayza Hospital during 1998. Of 396 alive neonates with intrauterine growth retardation, we took a representative sample (144). Maternal and perinatal Hospital Nacional natal indicators were evaluated. Results: Maternal age, prenatal control, preconceptional weight, maternal size, body mass index, maternal weight gain and hemoglobin during pregnancy do not show any significant differences. The most common associated pathologies concerning intrauterine growth retardation (p < 0,05) were multifetal gestotion, preeclampsia, uteroplacentol insufficiency, premature delivery and syphilis. The type of delivery was similar in both groups. Apgar score was significantly low in the cases, both atone and five minutes, without asphyxia compromise. Con...

OBJECTIVE: To determine the incidence and maternal characteristics, birth and neonatal delayed asymmetrical and symmetrical growth. MATERIALS AND METHODS: A descriptive, retrospective study of 396 live births with fetal growth retardation (RCF). RESULTS: The annual incidence was 10.1%, with asymmetrical 242 (61.1%) and symmetrical 154 (38.9%). In single mothers it was higher asymmetrical and cohabitants, symmetrical. There was adequate prenatal care in 71.7%. There were no differences between anthropometric measures, weight gain and maternal hemoglobin between the two types. Preeclampsia, urinary tract infection, premature rupture of membranes, previous cesarean section, premature birth and multiple pregnancy were associated pathologies more frequent, taking the last two significant relationship with symmetrical delay. The fetal malformations represented 4.5% and 4.1% in infants with sy...

OBJECTIVE: To evaluate the first experiences of HIV+ pregnant women who delivered at the Loayza General Hospital in 1996 and 1997. MATERIAL: Retrospective stay of 20 pregnant women HIV+. RESULTY: The incidence was 0,18% and increased from one year to anotherin about 50% (0,15% in 1996 to 0,22% in 1997). Four were classified as AIDS and sixteen as HIV+. Fourteen mothers were bettween 21 and 30 years old (70%) and four between 16 and 20 years (20%). Single mothers represent 35%. Secondary students or some with any year of high school total 95%, 20% of them began sexual activity before 15 years, 45% were pregnancy the first time. Twelve pregnant women (60%) bad an adequate prenatal care, they received zidovudine (AZT) during 10,7 weeks in average, giving hirth eight of them by elective cesarean section (5 arrived to the obstetric room with complete dilatation). Three patients presented cond...

Objectives: To determine the effectiveness of low dose salicylic acid acetate (aspirin) in preeclampsia prevention. Design: Clinical randomized trial. Setting: Loayza General Hospital Obstetrical Service. Material and methods: Forty-three primigravidae less than 20 weeks pregnant with hypocalciuria received 100 mg/d of salicylic acid acetate. Other 43 primigravidae with similar clinical characteristics were controls. Results: The incidence of preeclampsia was 16,3% in both groups. Conclusion: The use of low dose salicylic acid acetate did not change the incidence of preeclampsia in this group of patients.

Objetivos: Determinar la eficacia del uso de minidosis de ácido acetilsalicílico (aspirina) en la prevención de la preeclampsia. Diseño: Ensayo clínico aleatorio. Lugar: Servicio de Obstetricia del Hospital Arzobispo Loayza. Material y métodos: Se incluyó 43 primigestas con hipocalciuria, con menos de 20 semanas de gestación, a quienes se les administró 100 mg/día de ácido acetilsalicílico vía oral. Otras 43 primigestas con características clínicas similares no recibieron la medicación y sirvieron de control. Resultado: La incidencia de la preeclampsia fue 16,3% para ambos grupos. Conclusión: El uso de minidosis de ácido acetilsalicílico no disminuyó la incidencia de preeclampsia en este grupo de primigestas.

OBJECTIVES. To determine both endometrial hyperplasia associated risk factors and effective use of diagnostic procedures. DESIGN: Retrospective, clinical study. SETTING: Gynecology Service, Arzobispo Loayza National Hospital, a teaching hospital. PATIENTS: Women with abnormal uterine bleeding and/or thickened endometrium by ultrasound. INTERVENTIONS: Associated risk factors were determined in 196 women –152 premenopausal and 44 postmenopausal–, with histology diagnosis of either endometrial hyperplasia (with or without atypia) or normal endometrium (proliferative or secretory). x2, odds ratios, 95% confidence intervals and logistic regression were used. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were determined. MAIN OUTCOME MEASURES: Endometrial hyperplasia associated risk factors. ReSULTS. In the premenopausal group 34 had normal ...

OBJECTIVE. To determine fetal growth of appropriate and small for gestational age twins by ultrasound. MATERIAL AND METHODS. Live twin deliveries attended at A. Loayza General Hospital between January 1, 1996 and December 31, 2000, with minimum 3 ultrasound studies during pregnancy when biparietal diameter, abdominal circumference, femur length and estimated fetal weight were determined. Seventy-nine adequate (AGA) and small (SGA) for gestational age were studied, mcluding sexgender, placenta type and complications. RESULT. The abdominal circumference between twin AGA and SGA reaches a difference of 20 mm at 39,2 weeks, 15 mm at 35,6, and 10 mm at 31,1 weeks. Biparietal diameter differed 5 mm at 39,6 weeks, 4 mm at 30,4 and 3 mm at 25,2 weeks, Femur length reached maximum difference of 2,81 mm at 17,4 weeks and fetal weight 17% at 28,8 weeks.
