Cervical vaporization in LSIL and persistent HPV infection.

OBJECTIVE: To assess rates of negative cytology and high-risk HPV testing after CO2 laser treatment for low-grade lesions and persistent infection with high-risk HPV as well as factors that can influence these rates. MATERIAL AND METHODS: Between February 2011 and January 2015, 124 cervical vaporizations were performed with a CO2 laser in patients presenting persistent infection with high-risk HPV or LSIL of CIN I that had persisted for more than 2 years. Data on parity, condom use, oral contraceptive use, smoking, vaccination against HPV, and immune status were collected and the relationship with rates of negative cytology and high-risk HPV testing was studied. RESULTS: We performed cytology, colposcopic and high-risk HPV detection 6 months after treatment in 116 patients (93%). Seventy-nine percent of patients had benign cytology in this control and 60% had negative results for HPV. Both parameters were normalized in 54% of patients. Mean follow-up was 22.35 months. Rates of negative cytology testing showed no significant relationship with any of the variables studied. Regarding rates of negative high-risk HPV testing, there is a statistically significant relationship with age younger than 45 years; type of high-risk HPV other than 16 and 18; and nulliparity and condom use. Among patients with persistent HPV infection and abnormal cytology at 6 months of vaporization, 55% had normalized cytology results but only 14.7% had negative results for high-risk HPV at the end of follow-up. CONCLUSIONS: CO2 laser vaporization is a simple, safe, and successful outpatient treatment that can be performed without anesthesia.

[External cephalic version]. / Versión cefálica externa.

Objetives: To analyze the rate of successful external cephalic versions in our center and caesarean sections that would be avoided with the use of external cephalic versions. Material and methods: From January 2012 to March 2016 external cephalic versions carried out at our center, which were a total of 52. We collected data about female age, gestational age at the time of the external cephalic version, maternal body mass index (BMI), fetal variety and situation, fetal weight, parity, location of the placenta, amniotic fluid index (ILA), tocolysis, analgesia, and newborn weight at birth, minor adverse effects (dizziness, hypotension and maternal pain) and major adverse effects (tachycardia, bradycardia, decelerations and emergency cesarean section). Results: 45% of the versions were unsuccessful and 55% were successful. The percentage of successful vaginal delivery in versions was 84% (4% were instrumental) and 15% of caesarean sections. With respect to the variables studied, only significant differences in birth weight were found; suggesting that birth weight it is related to the outcome of external cephalic version. Probably we did not find significant differences due to the number of patients studied. Conclusion: For women with breech presentation, we recommend external cephalic version before the expectant management or performing a cesarean section. The external cephalic version increases the proportion of fetuses in cephalic presentation and also decreases the rate of caesarean sections.
