Difficult etonogestrel implant removals in South Africa: A review of 74 referred cases.
Ontology highlight
ABSTRACT: Objectives
To assess etonogestrel contraceptive implant location and outcomes among women referred for "difficult" removal to a specialist clinic in South Africa.Study design
We performed a retrospective review of cases referred to our clinic for removal of nonpalpable, deep, migrated, or damaged implants, or failed removals from March to August 2017.Results
Most (n = 68, 92%) of the 74 referrals were nonpalpable in our clinic. We used ultrasound for localization and successfully removed 72 implants (97%) in the outpatient clinic.Conclusion
With proper protocols and equipment, localization and removal of nonpalpable implants can be safely and effectively achieved in an outpatient African setting.Implications
Access to providers specially trained in ultrasound localization should be available in all settings where implants are offered. Providing timely access to safe and effective implant removals in routine and difficult cases is essential to ensuring that implant programs are in alignment with rights-based, client-centered family planning principles.

Project description:OBJECTIVE:To describe our experience with office removal of nonpalpable contraceptive implants at our referral center. METHODS:We performed a retrospective cohort study by reviewing the charts of patients referred to our family planning specialty center for nonpalpable or complex contraceptive implant removal from January 2015 through December 2018. We localized nonpalpable implants using high-frequency ultrasonography and skin mapping in radiology, followed by attempted removal in the office using local anesthesia and a modified vasectomy clamp. We abstracted information on demographics, implant location, and outcomes. RESULTS:Of 61 referrals, 55 patients attended their scheduled appointments. Seven patients had palpable implants; six elected removal. The other 48 patients had ultrasound localization, which identified 47 (98%) of the implants; the remaining patient had successful localization with computed tomography imaging. Nonpalpable implants were suprafascial (n=22), subfascial (n=25) and intrafascial (n=1); four of these patients opted to delay removal. Of 50 attempted office removals, all palpable (n=6), all nonpalpable suprafascial (n=21 [100%, 95% CI 83-100%]), and 19 out of 23 (83%, 95% CI 67-98%) subfascial implants were successful. Three of the four patients with failed subfascial implant office removal had successful operating room removal with a collaborative orthopedic surgeon; the other patient sought removal elsewhere. Transient postprocedure neuropathic complaints were noted in 7 out of 23 (30%, 95% CI 12-49%) subfascial and 1 out of 21 (5%, 95% CI 0-13%) suprafascial removals (P=.048). Nonpalpable implants were more likely to be subfascial in nonobese patients (24/34, 71%) as compared with obese (1/13, 8%) patients (P<.001). Seven (28%) of the 25 subfascially located implants had been inserted during a removal-reinsertion procedure through the same incision. CONCLUSION:Most nonpalpable contraceptive implants can be removed in the office by an experienced subspecialty health care provider after ultrasound localization. Some patients may experience transient postprocedure neuropathic pain. Nonpalpable implants in thinner women are more likely to be in a subfascial location.

Project description:ObjectivesTo describe the presentation, influence of previous treatment and diagnosis in juvenile dogs presenting with pyrexia to a UK referral centre.Materials and methodsClinical records of dogs aged 1 to 18 months presenting with a problem list including pyrexia (??39?2°C) that was reproducible during referral hospitalisation were retrospectively reviewed. Signalment, history - including previous treatment, clinical examination findings and diagnosis were recorded. Diagnoses were categorised as non-infectious inflammatory, infectious, congenital, neoplastic and miscellaneous. The influence of previous treatment on the ability to reach a final diagnosis was analysed.ResultsA total of 140 cases was identified. Diagnosis was reached in 115 cases. Non-infectious inflammatory disease was identified in 91 cases (79%), infectious disease in 19 cases (17%), a congenital disorder in four dogs (3%) and neoplasia in one dog (1%). Breeds most commonly identified were Border collies (17/140; 12%), beagles (16/140; 11%), Labrador retrievers (11/140; 8%), springer spaniels (9/140; 6%) and cocker spaniels (8/140; 6%). Before presentation, most dogs had received antibiotics (83/140; 59%), non-steroidal anti-inflammatory drugs (84/140; 60%) or steroids (9/140; 6%), either alone or in combination. Neither antibiotics nor non-steroidal anti-inflammatory drugs influenced the ability to reach a diagnosis. Steroid-responsive meningitis-arteritis comprised 55 of 91 (60%) individuals of the non-infectious inflammatory cohort. All four dogs diagnosed with congenital disorders were Border collies.Clinical significanceNon-infectious inflammatory disease, particularly steroid-responsive meningitis-arteritis, immune-mediated polyarthritis and metaphyseal osteopathy, was commonly diagnosed in this population of pyrexic juvenile dogs.

Project description:ObjectiveTo evaluate topiramate and etonogestrel pharmacokinetic interactions in contraceptive implant users.MethodsWe conducted a prospective, noninferiority study with healthy women using etonogestrel implants continuously for 12-36 months. We measured baseline serum etonogestrel concentrations and then began a 6-week titrated topiramate regimen to standard migraine (100 mg/day) and epilepsy (400 mg/day) dosages. We repeated serum etonogestrel concentrations at 3 weeks (100 mg/day), 4 weeks (200 mg/day), and 6 weeks (400 mg/day) of topiramate therapy. We measured etonogestrel using a validated liquid chromatography-tandem, mass-spectrometry assay and tested for noninferiority (less than 30% decrease) in serum etonogestrel concentrations from baseline.ResultsWe enrolled 48 total participants; 32 completed 3 weeks, 31 completed 4 weeks, and 27 completed all follow-up visits. Participants' median age was 25.3 years (range 18.3-37.2), median body mass index (BMI) was 25.5 kg/m2 (range 18.7-42.2), and median duration of implant use was 24 months (range 12-36). Median etonogestrel concentrations were 142 pg/mL (range 76.2-771) at baseline, 126 pg/mL (range 72.4-585) at 3 weeks, 119 pg/mL (range 65.6-542) at 4 weeks, and 105 pg/mL (46.2-859) at 6 weeks. The 95% CIs for mean percent change in serum etonogestrel concentrations from baseline were [-37.3%+16.9%], [-45.4%+5.2%], and [-66.8%+24.8%] at 3 weeks, 4 weeks, and 6 weeks, respectively. Excluding one participant who had a serum etonogestrel concentration less than 90 pg/mL at baseline, 30.8% of participants (8/26, 95% CI 14.3-51.8%) had a serum etonogestrel concentration less than 90 pg/mL at 6 weeks.ConclusionThough only a mild enzyme-inducing antiepileptic drug, concomitant topiramate use led to inferior serum etonogestrel concentrations among implant users, with a significant proportion reaching etonogestrel concentrations below the threshold for ovulatory suppression when taking antiepileptic dosages of topiramate.Funding sourceThis study was primarily funded through an Investigator-Initiated Study grant from Merck Sharp & Dohme Corp [MISP#57073].

Project description:ObjectiveTo estimate whether serum etonogestrel concentrations influence bleeding patterns and related side effects in contraceptive implant users.MethodsWe conducted a prospective cross-sectional study with healthy, reproductive-aged women using etonogestrel implants for 12-36 months. Participants completed a brief questionnaire to assess their current bleeding pattern and any experience of abnormal bleeding with the implant. We then measured serum etonogestrel concentrations. We also reviewed the charts of participants to determine whether a prescription for oral contraceptive pills was ever given for treatment of implant-related bothersome bleeding. We performed multivariable logistic regression to test for associations between serum etonogestrel concentrations and both bleeding patterns and related side effects.ResultsWe enrolled 350 women, and 59.4% reported having experienced abnormal bleeding with the contraceptive implant. Only 14.9% of participants reported amenorrhea and 37.7% reported monthly periods. Among participants with reviewable medical records (n=253), roughly 20% had received a prescription for oral contraceptive pills during implant use. Increasing serum etonogestrel concentrations were significantly associated with increasing odds of reporting abnormal bleeding (adjusted odds ratio [aOR] 1.005, P=.015) and increasing odds of having received an oral contraceptive pill prescription (aOR 1.008, P=.002). For every 100 pg/mL increase in serum etonogestrel concentration, contraceptive implant users in this study had 1.6 times the odds of reporting abnormal bleeding and 2.3 times the odds of having received a prescription as treatment for bothersome bleeding.ConclusionWe found both objective and subjective evidence that higher levels of progestin from the contraceptive implant were associated with bleeding side effects experienced by women in this study. Pharmacologic variation may influence the side effects women experience with a variety of hormonal contraceptive methods, in turn affecting patient satisfaction and discontinuation rates.

Project description:ObjectiveTo compare plasma etonogestrel concentrations sampled from the contralateral- versus ipsilateral-to-implant arm.Study designSub-analysis of a cross-sectional study in Botswana in 33 participants who provided contralateral and ipsilateral blood samples.ResultsPlasma etonogestrel concentrations in contralateral and ipsilateral specimens were highly correlated (correlation coefficient = 0.99; p < 0.0001). Bland-Altman analysis of agreement showed that etonogestrel levels were on average 5.9 pg/mL higher (2.1%) in ipsilateral compared to contralateral specimens (95% confidence interval: -4.1, 15.9 pg/mL).ConclusionsWe found no meaningful differences in plasma etonogestrel concentrations between samples taken from the contralateral- versus ipsilateral-to-implant arm.ImplicationsOur data suggest that etonogestrel plasma concentrations are unlikely to be meaningfully different between samples drawn from the ipsilateral- versus the contralateral-to-implant arms in etonogestrel contraceptive implant users.

Project description:ObjectiveTo determine whether serum etonogestrel concentrations in contraceptive implant users are associated with certain individual patient characteristics.Study designWe enrolled reproductive-age women using etonogestrel contraceptive implants between 12-36 months duration and measured a single serum etonogestrel concentration. Participants also completed a questionnaire about demographics.ResultsWe enrolled 350 participants; median age was 22.5 years (range 18.0-39.1), median months of implant use was 26.0 (range 12.0-36.0), and median body mass index was 25.7 kg/m2 (range 18.5-52.0). Our study population was primarily white/Caucasian (46.6% [163/350]) and Hispanic/Latina ethnicity (51.4% [180/350]). The median serum etonogestrel concentration was 137.4 pg/ml and etonogestrel concentrations varied 12.4 fold in the population (range 55.8-695.1 pg/ml). Using forward stepwise linear regression, months of implant use (β=-1.74, p<.001) and body mass index (β=-3.10, p<.001) were both significantly associated with decreased serum etonogestrel concentration with Black/African American race as a positive effect modifier (β=18.24, p=.099); R-squared for the model=0.13.ConclusionsIndividuals demonstrated a wide variability in serum etonogestrel concentrations, which can potentially affect side-effect profiles and efficacy. Increasing body mass index and longer duration of implant use were associated with small decreases in serum etonogestrel concentrations, while self-reported Black/African American race was associated with a non-significant increase. Despite these findings, most of etonogestrel variability was unaccounted for, suggesting that other clinical, pharmacologic, and genetic factors contributing to variability in etonogestrel concentrations remain to be determined.ImplicationsAlthough increases in body mass index are associated with lower etonogestrel levels in contraceptive implant users, the majority of women will maintain serum concentrations that consistently suppress ovulation. Furthermore, certain patient characteristics can only explain a small portion (13%) of the variability in serum etonogestrel levels among contraceptive implant users.
