RESUMEN

BACKGROUND: Increasingly patients with unilateral breast cancer elect to undergo bilateral mastectomy with subsequent reconstruction. Studies have aimed to better identify the risks associated with performing mastectomy on the noncancerous breast. Our study aims to identify differences in complications between therapeutic and prophylactic mastectomy in patients undergoing implant-based breast reconstruction. METHODS: A retrospective analysis of implant-based breast reconstruction from 2015 to 2020 at our institution was completed. Patients with less than 6-month follow-up after final implant placement had reconstruction using autologous flaps, expander or implant rupture, metastatic disease requiring device removal, or death before completion of reconstruction were excluded. McNemar test identified differences in incidence of complications for therapeutic and prophylactic breasts. RESULTS: After analysis of 215 patients, we observed no significant difference in incidence of infection, ischemia, or hematoma between the therapeutic and prophylactic sides. Therapeutic mastectomies had higher odds of seroma formation ( P = 0.03; odds ratio, 3.500; 95% confidence interval, 1.099-14.603). Radiation treatment status was analyzed for patients with seroma; 14% of patients unilateral seroma of the therapeutic side underwent radiation (2 of 14), compared with 25% patients with unilateral seroma of the prophylactic side (1 of 4). CONCLUSIONS: For patients undergoing mastectomy with implant-based reconstruction, the therapeutic mastectomy side has an increased risk of seroma formation.

RESUMEN

Stiff-person syndrome (SPS) is a rare, autoimmune, neuromuscular disorder that manifests with axial and proximal muscle stiffness, rigidity, and painful muscle spasms, often causing progressive disability due to limited movement. First-line therapies comprise symptomatic management with γ-aminobutyric acid-modulating drugs such as benzodiazepines and baclofen. Patients resistant to these treatments are often given intravenous immunoglobulin (IVIg). Severe disease refractory to first-line therapy and IVIg may be treated with therapeutic plasma exchange (TPE) or immunomodulatory agents such as rituximab. Current evidence derived from case reports and case series has shown that roughly half of SPS patients treated with TPE report benefits. Here, we report the case of a 68-year-old man with a 20-year history of severe SPS and recurrent falls who was admitted to the emergency department for a traumatic hip fracture. He had significant rigidity in the axial and extremity muscles with persistent spasms of the quadriceps femoris muscle. Postoperatively, he was unable to participate in physical therapy (PT) due to these symptoms. He previously failed treatment with diazepam, baclofen, and monthly IVIg. Under our care, he underwent seven TPE treatments. By the end of treatment, he reported significant improvement in mobility with a resolution of muscle spasms and was able to be discharged to inpatient rehabilitation. This suggests that TPE may offer an effective, safe treatment modality for patients with severe refractory SPS that may significantly improve mobility and disability associated with the disease.
