Wernicke encephalopathy (WE) is an acute neurological disorder resulting from vitamin B1 deficiency, which is common in chronic alcoholism. We report a rare case of WE due to hyperemesis gravidarum in a 25-year-old pregnant patient at 13 weeks and 5 days of gestation. Initially, the disease manifested as weakness, mental confusion, anterograde amnesia, and visual and auditory hallucinations. The diagnosis was established after the detection of suggestive findings of WE in the thalamus by magnetic resonance imaging (MRI) and a rapid improvement in the patient's clinical status subsequent to treatment with thiamine. Hyperemesis is a rare cause of WE, which makes the reported case important in the literature and reinforces the need for attention in clinical practice to rare but important complications of this common condition (hyperemesis gravidarum).

Objective To describe the feasibility of an ultrasound‐guided repositioning technique for partially expelled intrauterine devices (IUDs) without use of sedation. Methods This was a descriptive feasibility study of patients with a partially expelled IUD managed in our outpatient clinic from January 2016 to February 2020. The partially expelled IUDs (vertical arm extending partially or entirely through the cervical canal) were repositioned at the uterine fundus using Hartmann alligator forceps under ultrasound guidance. Paracervical or intracervical anesthesia and prophylactic antibiotics were not used. Data related to the procedure and 6‐month follow‐up were extracted from patient medical records. The primary outcome was the success rate of the repositioning procedure, defined as ultrasound confirmation of the entire IUD located above the internal os. Secondary outcomes included the retention and expulsion rates of the repositioned IUD at 6 months after the procedure and description of complications. Results We included data from 55 women with a partially expelled IUD (35 levonorgestrel IUDs and 20 copper IUDs) referred for repositioning. Ultrasound‐guided repositioning of the IUD was successful in 51 (92.7%) cases, while the procedure was not completed in four patients due to pain. Of the 55 procedures, 48 (87.3%) were performed by obstetrics and gynecology trainees under the supervision of a senior specialist. Among the 51 successfully repositioned IUDs, nine (17.6%) were expelled within 6 months after the procedure and six patients were lost to follow‐up. No uterine perforation or infection‐related complications occurred within 6 months of the procedure. Conclusion The ultrasound‐guided repositioning technique appears to be a safe and feasible approach for partially expelled IUDs. © 2022 International Society of Ultrasound in Obstetrics and Gynecology.
