Alternative Insertion Site of Nexplanon: Description of a Case Report and Systematic Review of the Literature

''Inserting the etonorgestrel implant into the thigh: A case report''

Etonorgestrel implant is inserted on the inner surface of the non-dominant medial upper arm in women, over the triceps area. However, this case report aims to describe an alternative insertion site for etonorgestrel implant - the medial side of the thigh - in nephropathic patients with arteriovenous fistulas undergoing hemodialysis.

The influence of factors associated with past reproductive histories on migraines in middle-aged premenopausal women: a nationwide population-based study in Republic of Korea

Introduction

Women can experience various reproductive events, such as pregnancy, childbirth, lactation, and contraception, which cause long-term changes in female hormones. In middle-aged women, the prevalence of migraine is high, and a clear gender difference is evident. This study investigated the effects of factors associated with past reproductive events on the risk of new migraine in middle-aged premenopausal women.

Methods

The influence of reproductive factors on migraine in middle-aged women was investigated using the Korean National Health Insurance Service (KNHIS) and Korean Health Examination (KHE) databases. The reproductive factors of interest were parity, breastfeeding, and oral contraceptive (OC) use. The study included 949,704 middle-aged premenopausal women 40-60 years of age. The study population was divided into two groups based on new diagnosis of migraine during the follow-up period (2009-2018).

Results

The risk of new migraine tended to increase in the primiparous (hazard ratio, HR: 1.179; 95% confidence interval, CI: 1.137-1.221) and multiparous groups (HR: 1.181; 95% CI: 1.142-1.221) compared with the nulliparous group. The breastfeeding ≥12 months group (HR: 1.071; 95% CI: 1.052-1.091) showed a significantly increased risk of new migraine compared with the non-breastfeeding group. All women in the OC groups (< 1 year, HR: 1.048; 95% CI: 1.028-1.069 and ≥ 1 year, HR: 1.100; 95% CI: 1.067-1.134) showed a higher risk of new migraine than those in the non-OC group.

Conclusion

The results of the current study indicate that childbirth, longer breastfeeding, and OC use may be associated with a higher risk of new migraine in middle-aged premenopausal women.

Nonpalpable implant removals at centre of experience in France: a cohort study

STUDY DESIGN

In this retrospective study, we reviewed all cases referred to our specialised centre for nonpalpable contraceptive implants from January 2018 to August 2022.

RESULTS

Out of the cohort studied, 47 female subjects exhibited nonpalpable implants. The implant was nonpalpable for thirty-six patients (76,6%) immediately after the insertion whereas it was not palpable several months after the insertion for eleven patients (23.4%). Twelve patients (25.5%) had one or more failed removal attempts before referral.All 47 implants were successfully visualised via ultrasound in the upper arm: 40 implants (85.1%) were located in the subdermal tissue, 4 (8.5%) were intrafascial and 3 (6.4%) were intramuscular. Depth of the implant was 4.0 mm [1.7 - 12.0]. No clinical factors were statistically associated with differences in depth or location (subdermal vs subfascial). Removal procedures were mainly under local anaesthesia in 74.5% of cases in an outpatient setting. There were two Clavien-Dindo grade 1 complications (one case of cutaneous scar dehiscence and one transient postoperative neuropathic complaint in the upper arm resolved within 3 months under analgetics).

CONCLUSIONS

Identification of deep implants requires following the ultrasound modality protocol. Ultrasound detection makes easy and safe implant removal. Training programs for the insertion as well as for the removal of correct and incorrect inserted implants should be continued and developed all around the world.

Major Depression and Panic Disorder Associated with Implanon Implant: A Case Report

This report presents a case study of a patient who experienced depression and panic disorder symptoms associated with the use of Implanon, a contraceptive implant. This is a rare case of related prevalence data. The purpose of this report is to explore the potential relationship between Implanon and the development of these psychiatric conditions. The findings suggest a possible link between Implanon and the onset or exacerbation of depression and panic disorder symptoms. Further research is warranted to investigate the underlying mechanisms and determine the prevalence of such adverse effects.

Special Issue "New Insights into Contraception"

Today, a diverse range of contraceptive techniques is available to women; this, coupled with continued positive trends in female children and adults' educational attainment, will hasten declines in fertility and continue to slow population growth [...].
