Gretchen S Stuart, Shanthi S Ramesh
Female sterilization is relied on by nearly one in three women aged 35-44 years in the United States. Sterilization procedures are among the most common procedures that obstetrician-gynecologists perform. The most frequent sterilization procedures include postpartum tubal ligation, laparoscopic tubal disruption or salpingectomy, and hysteroscopic tubal occlusion. The informed consent process for sterilization is crucial and requires shared decision-making between the patient and the health care provider. Counseling should include the specific risks and benefits of the specific surgical approaches...

Long-acting reversible contraception, which include etonogestrel subdermal hormonal implants, has high efficiency rates in preventing teen pregnancy. Although these numbers are increasing, teens have the lowest long-acting reversible contraception usage rate of any group, which the American Congress of Obstetricians and Gynecologists addressed with recommendations for Nexplanon placement for teens. The American Congress of Obstetricians and Gynecologists has recommended support for increased use and training of practitioners and pediatricians to gain momentum...

BACKGROUND: Subdermal implantable contraceptives are highly effective, approved in over 60 countries, and used by millions of women. Due to simple insertion and removal protocols, these procedures are often performed in the outpatient clinic setting, and procedural complications are rare. However, given the location of the implant in the medial antebrachial interval, there is a risk of neurovascular injury, especially with malpositioned or deeply placed implants. METHODS: We present a case of proximal median nerve injury leading to severe neuropathy after attempted removal of a subdermal implantable contraceptive requiring neurolysis and tendon transfers...

BACKGROUND: Magnetic subdermal implants have never been studied in the context of magnetic fixation of an external device to the body's surface. Excessive attractive force between the implant and the external device may compromise local circulation due to mechanical compression, leading to necrosis. OBJECTIVE: To evaluate the feasibility of transcutaneous magnetic fixation and assess secondary skin changes when subjected to a continuous static magnetic field. METHODS: Using the pig as an animal model, 72 implants were introduced in 12 animals...

Soft-tissue augmentation and implants are increasingly seen by the radiologist as more techniques emerge for a variety of indications and locations. Some surgical and implant procedures are performed for purely cosmetic reasons in otherwise healthy patients seeking to improve their body image, and some are performed for reconstruction after cancer or other chronic illnesses. Abdominoplasty, liposuction, and autologous fat grafting can be performed for abdominal and gluteal contouring. Injection of liquid injectable silicone has historically been fraught with legal issues, although it continues to be used for augmentation in a variety of anatomic locations...

Andreas Bahmer, Youssef Adel, Uwe Baumann
HYPOTHESIS: Triphasic pulse stimulation of the auditory nerve can prevent unintended facial nerve stimulation (FNS) due to a different electromyographic (EMG) input-output function compared with biphasic pulses. BACKGROUND: FNS is sometimes observed in cochlear implant (CI) users as an unpleasant side effect of electrical stimulation using biphasic pulse patterns (BPP). Clinical remedies to alleviate FNS are 1) to extend stimulus phase duration or 2) to completely deactivate the electrode...

Absorbable implants made of magnesium alloys may revolutionize surgical intervention, and fine magnesium wire will be critical to many applications. Functionally, the wires must have sufficient mechanical properties to withstand implantation and in-service loading, have excellent tissue tolerance, and exhibit an appropriate degradation rate for the application. Alloy chemistry and thermomechanical processing conditions will significantly impact the material's functional performance, but the exact translation of these parameters to implant performance is unclear...

Percutaneous osseointegrated (OI) prostheses directly connect an artificial limb to the residual appendicular skeleton via a permanently implanted endoprosthesis with a bridging connector that protrudes through the skin. The resulting stoma produces unique medical and biological challenges. Previously, a study using a large animal amputation model indicated that infection could be largely prevented, for at least a 12-month period, but the terminal epithelium continued to downgrow. The current study was undertaken to test the longer-term efficacy of this implant construct to maintain a stable skin-implant interface for 24 months...

OBJECTIVE: To assess temporal trends in the uptake and continuation of the etonogestrel subdermal implant in a large private practice setting. METHODS: This was a retrospective cohort study based on billing records from a large multispecialty private practice in Las Vegas, Nevada. We looked at women of all ages seeking long-acting reversible contraception (LARC) between January 1, 2013, and December 31, 2016. The main outcome measure was uptake of the etonogestrel subdermal implant, expressed as a fraction of all insertions of LARC across four calendar years (2013-2016)...

PURPOSE OF REVIEW: Subdermal contraceptive implant insertions have rapidly increased worldwide. These devices are usually removed 3-5 years after insertion. Although removals are generally straightforward, difficult removals can occur. This review discusses the overall approach to potentially problematic removals and the appropriate steps to avoid complications and safely remove implants. RECENT FINDINGS: Given the rapid uptake of contraceptive implants and subsequent need for removals, an Implants Removal Task Force was formed to create standard protocols for difficult implant removals worldwide...

REVIEW
Richard N Rosenthal, Viral V Goradia
Opioid use disorders (OUDs) have long been a global problem, but the prevalence rates have increased over 20 years to epidemic proportions in the US, with concomitant increases in morbidity and all-cause mortality, but especially opioid overdose. These increases are in part attributable to a several-fold expansion in the prescription of opioid pain medications over the same time period. Opioid detoxification and psychosocial treatments alone have each not yielded sufficient efficacy for OUD, but μ-opioid receptor agonist, partial agonist, and antagonist medications have demonstrated the greatest overall benefit in OUD treatment...
