Fertility and early pregnancy outcomes after conservative treatment for cervical intraepithelial neoplasia

BACKGROUND: Cervical intra-epithelial neoplasia (CIN) typically occurs in young women of reproductive age. Although several studies have reported the impact that cervical conservative treatment may have on obstetric outcomes, there is much less evidence for fertility and early pregnancy outcomes. OBJECTIVES: To assess the effect of cervical treatment for CIN (excisional or ablative) on fertility and early pregnancy outcomes. SEARCH METHODS: We searched in January 2015 the following databases: the Cochrane Gynaecological Cancer Specialised Register, Cochrane Central Register of Controlled Trials (CENTRAL; The Cochrane Library, Issue 12, 2014), MEDLINE (up to November week 3, 2014) and EMBASE (up to week 52, 2014). SELECTION CRITERIA: We included all studies reporting on fertility and early pregnancy outcomes (less than 24 weeks of gestation) in women with a history of CIN treatment (excisional or ablative) as compared to women that had not received treatment. DATA COLLECTION AND ANALYSIS: Studies were classified according to the treatment method used and the fertility or early pregnancy endpoint. Pooled risk ratios (RR) and 95% confidence intervals (CI) were calculated using a random-effects model and inter-study heterogeneity was assessed with I(2). Two review authors (MK, AM) independently assessed the eligibility of retrieved papers and risk of bias. The two review authors then compared their results and any disagreements were resolved by discussion. If still unresolved, a third review author (MA) was involved until consensus was reached. MAIN RESULTS: Fifteen studies (2,223,592 participants - 25,008 treated and 2,198,584 untreated) that fulfilled the inclusion criteria for this review were identified from the literature search. The meta-analysis demonstrated that treatment for CIN did not adversely affect the chances of conception. The overall pregnancy rate was higher for treated (43%) versus untreated women (38%; RR 1.29, 95% CI 1.02 to 1.64; 4 studies, 38,050 participants, very low quality), although the inter-study heterogeneity was considerable (P < 0.01). The pregnancy rates in treated and untreated women with an intention to conceive (88% versus 95%, RR 0.93, 95% CI 0.80 to 1.08; 2 studies, 70 participants, very low quality) and the number of women requiring more than 12 months to conceive (14% versus 9%, RR 1.45, 95% CI 0.89 to 2.37; 3 studies, 1348 participants, very low quality) were no different. Although the total miscarriage rate (4.6% versus 2.8%, RR 1.04, 95% CI 0.90 to 1.21; 10 studies, 39,504 participants, low quality) and first trimester miscarriage rate (9.8% versus 8.4%, RR 1.16, 95% CI 0.80 to 1.69, 4 studies, 1103 participants, low quality) was similar for treated and untreated women, CIN treatment was associated with an increased risk of second trimester miscarriage, (1.6% versus 0.4%, RR 2.60, 95% CI 1.45 to 4.67; 8 studies, 2,182,268 participants, low quality). The number of ectopic pregnancies (1.6% versus 0.8%, RR 1.89, 95% CI 1.50 to 2.39; 6 studies, 38,193 participants, low quality) and terminations (12.2% versus 7.4%, RR 1.71, 95% CI 1.31 to 2.22; 7 studies, 38,208 participants, low quality) were also higher in treated women.The results should be interpreted with caution. The included studies were often small with heterogenous design. Most of these studies were retrospective and of low or very low quality (GRADE assessment) and were therefore prone to bias. Subgroup analyses for the individual treatment methods and comparison groups and analysis to stratify for the cone length was not possible. AUTHORS' CONCLUSIONS: This meta-analysis suggests that treatment for CIN does not adversely affect fertility, although treatment was associated with an increased risk of miscarriage in the second trimester. These results should be interpreted with caution as the included studies were non-randomised and many were of low or very low quality and therefore at high risk of bias. Research should explore mechanisms that may explain the increase in mid-trimester miscarriage risk and stratify this impact of treatment by the length of the cone and the treatment method used

Long-term retinal changes after strabismus surgery, suspected signs of past scleral perforations

Purpose: Scleral perforation during strabismus surgery is considered a rare complication that usually results in no significant consequences. The true rate of such occurrences is difficult to evaluate due to the young age of most patients and the occult nature of most events. This study aimed to evaluate long-term retinal changes under the suture areas in patients post-strabismus surgery as presumed signs indicating past undiscovered scleral perforations. Methods: The study population consisted of patients with a follow-up of at least 10 years post-strabismus surgery at the [redacted for review] Eye Institute and with no known retinal conditions as well as with wide fundus visibility. We performed slit-lamp retinal periphery examinations in search of retinal scars or changes at the suture sites. Results: Seventy-one eyes from 43 patients were examined. The mean age (±standard deviation [SD]) at the time of examination was 27 years (±14), and the mean number of strabismus surgeries per patient was 1.8. Three of the examined eyes showed retinal changes at the suture sites, yielding an overall incidence rate of suspected perforation/penetration of 4.2% per eye and 3.6% per strabismus surgery. These three patients were all asymptomatic. Conclusion: Scleral perforations during strabismus surgeries could remain unnoticed since a comprehensive exam of the retinal periphery is challenging in young children, especially during the postoperative period. While retinal changes caused by inadvertent scleral perforations appear to have no clinical sequelae in a time frame of 10 years, such changes should be noted for future fundoscopic examinations

Subjective versus objective refraction in healthy young adults

Abstract Purpose To evaluate objective and subjective refraction differences in healthy young adults. Methods Data concerning candidates for the Israeli Air Force Flight Academy, as well as active air force pilots in all stages of service who underwent a routine health checkup between the years 2018 and 2019 were retrospectively analyzed. Objective refraction measured using a single autorefractometer was compared with subjective refraction measured by an experienced military optometrist during the same visit. The results were converted to power vectors (spherical equivalent [SE], J0, and J45). To interpret astigmatism using power vector values, the cylinder power (Cp) was determined. Results This study included 1,395 young adult participants. The average age was 22.17 years (range, 17–39, 84.8% males). The average SE was − 0.65 ± 1.19 diopter (D) compared with − 0.71 ± 0.91D in the auto- and subjective refraction, respectively (p = 0.001). Cp was 0.91 ± 0.52D and 0.67 ± 0.40D, respectively (p < 0.001). This difference was more common in older participants (p < 0.001). J0 and J45 value differences were not significant. The absolute SE value of subjective refraction was lower in the myopic (p < 0.001) and hyperopic (p < 0.001) patients. Conclusions Young hyperopic participants tended to prefer “less plus” in subjective refraction compared with autorefraction. Young myopic participants tended to prefer “less minus” in subjective refraction compared with autorefraction. All participants, but mainly older participants, preferred slightly “less Cp” than that measured using autorefraction; The astigmatic axis did not differ significantly between the methods

COVID-19’s Influence on Ocular Emergency Visits at a Tertiary Referral Center and Its Relationship to Emergency Indications by the American Academy of Ophthalmology

Purpose. To examine the trends of ocular emergency admissions during the COVID-19 pandemic at a tertiary care center. Methods. The study’s sample consisted of all patients who were seen in the ophthalmic emergency room (OER) between March 15 and April 15, 2020 (during the COVID-19 pandemic) and in the same time frame of the previous year. The cases were categorized as urgent vs. nonurgent according to the AAO urgency guidelines during the coronavirus period, and the ability to treat the case with telemedicine was evaluated retrospectively. Results. A total of 553 patients were admitted to the OER during the pandemic period, whereas in the same time frame of the previous year, 1,069 were admitted. The female/male proportion was 526/543 (49.2%/50.8%) in 2019 and 258/259 (46.7%/53.3%) the following year. Age (years, average ± SD) was 44.7 ± 24.5 in 2019 and 47.9 ± 23.4 in 2020. There were more self-referrals in 2020 compared to 2019 (41.1% vs. 32.6%; p=0.0004). The time spent in the OER was reduced from 109 ± 74 (minutes, average ± SDV) in 2019 to 73 ± 51 in 2020 (p<0.0001). The most common cause of OER examinations in 2020 was related to the posterior segment of the eye (23.9%), whereas infection and inflammation of the anterior segment were the most common causes in 2019 (35.5%). Urgency by AAO standards was in agreement in 26.7% admissions in 2019 and 35.6% in 2020 (p=0.0002). Conclusion. The COVID-19 pandemic has influenced several aspects of the OER, including the number of referrals, type of ophthalmic emergency, the time spent in the OER, and the need for emergent treatment. Our change in the treatment algorithm was in agreement with the AAO recommendations during the pandemic

Fertility conserving management of early cervical cancer

Background: Presently, for those diagnosed with early cervical cancer who wish to conserve their fertility, there is the option of radical trachelectomy. Although successful, this procedure is associated with significant obstetric morbidity. The recurrence risk of early cervical cancer is low and in tumors measuring less than 2 cm; if the lymphatics are negative, the likelihood of parametrial involvement is less than 1%. Therefore, pelvic lymph nodes are a surrogate marker of parametrial involvement and radical excision of the parametrium can be omitted if they are negative. Objective: The aim of this study was to report our experience of the fertility conserving management of early cervical cancer with repeat large loop excision of the transformation zone and laparoscopic pelvic lymph node dissection. Methods: Between 2004 and 2011, a retrospective review of cases of early cervical cancer who had fertility conserving management within Glasgow Royal Infirmary was done. Results: Forty-three patients underwent fertility conserving management of early cervical cancer. Forty were screen-detected cancers; 2 were stage IA1, 4 were stage IA2, and 37 were stage IB1. There were 2 central recurrences during the follow-up period. There have been 15 live children to 12 women and there are 4 ongoing pregnancies. Conclusions: To our knowledge, this is the largest case series described and confirms the low morbidity and mortality of this procedure. However, even within our highly select group, there have been 2 cases of central recurrent disease. We, therefore, are urging caution in the global adoption of this technique and would welcome a multicenter multinational randomized controlled trial
