[Asymptomatic bacteriuria among pregnant women. An underestimated threat]. / Bacteriuria asintomática en mujeres embarazadas. Una amenaza subestimada.

BACKGROUND: Urinary tract infection is a common pregnancy complication. Asymptomatic bacteriuria (AB) can trigger the development of serious complications affecting both the mother and the fetus. OBJECTIVE: Determine the frequency of AB among pregnant women attending to antenatal care at the family medicine clinic number 1 of the Instituto Mexicano del Seguro Social, located in Ciudad Obregón, Sonora. METHODOLOGY: A longitudinal study was carried out from September to December 2004. Seventy-two 72 pregnant women with gestational age of 24 weeks or less were followed up during four months. All pregnant women were selected by a non-probabilistic method. Every patient had a monthly urine culture during the follow up period. RESULTS: Among the 72 pregnant women, 16.7% developed symptomatic urinary infections during the follow-up and 25% had at least one positive urine culture without urinary symptoms, being classified as AB, thus receiving treatment. Frequency of positive urine cultures was common at first and fourth months of follow-up. CONCLUSION: Urine culture is an important component of prenatal care, and helps in identifying a significant number of urinary tract infections that would go otherwise undetected.

[Comparison between hysterosonography and hysterosalpinography in the study of endometrial abnormalities in infertility patients]. / Comparación entre histerosonografía e histerosalpingografía en el estudio de anormalidades endometriales en pacientes con esterilidad.

OBJECTIVE: We compare effectiveness between HSS and HSG for detection of endometrial abnormalities among patient with infertility. DESIGN OF THE STUDY: Prospective, cross section, comparative. MATERIAL AND METHODS: 33 patients were studied. HSS and HSG were carried out. The images of both studies were compared, settled down a presumptive diagnosis of normality or abnormality. The analysis included percentage of agreement, coefficient of agreement Kappa, square Ji, reason of verisimilitude. RESULTS: Of 33 studied patients was diagnostics correlation in 17 (52%). The pathologies with more correlation were congenital malformations and submucous miomas, with less correlation were adherences. Other opposing pathologies were polyps and corioplacentary remains. In 9 patients (27%) we find normality in both studies. When comparing the positive studies in each group we don't find differs statistically significant (P > 0.05). The association among both techniques was high (K = 0.70). The reason of verisimilitude of the tests was 98% for HSS and 90% for HSG. CONCLUSIONS: Both studies are useful to evaluate the uterine cavity. However histerosonography has bigger sensibility and specificity, besides is a quick, easy, and economic study, with less discomfort and complications than histerosalpingography.
