OCT Biomarkers and Visual Acuity in the Treatment of Diabetic Macular Edema

At baseline, visual acuity and the extent of vertical intraretinal fluid were predictive of better visual outcomes for 196 patients with diabetic macular edema who received tightly controlled treatment with 2mg intravitreal aflibercept injections.

The Association of Season of Surgery and Patient Reported Outcomes following Total Hip Arthroplasty

Background

Understanding the impact of situational variables on surgical recovery can improve outcomes in total hip arthroplasty (THA). Literature examining hospital outcomes by season remains inconclusive, with limited focus on patient experience. The aim of this study is to investigate if there are differences in hospital and patient-reported outcomes measures (PROMS) after THA depending on the season of the index procedure to improve surgeon preoperative counseling.

Methods

A retrospective chart review was performed on patients undergoing primary THA at a single large academic center between January 2013 and August 2020. Demographic, operative, hospital, and PROMs were gathered from the institutional electronic medical record and our institutional joint replacement outcomes database.

Results

6418 patients underwent primary THA and met inclusion criteria. Of this patient population, 1636 underwent surgery in winter, 1543 in spring, 1811 in summer, and 1428 in fall. PROMs were equivalent across seasons at nearly time points. The average age of patients was 65 (+/- 10) years, with an average BMI of 29.3 (+/- 6). Rates of complications including ED visits within 30 days, readmission within 90 days, unplanned readmission, dislocation, fracture, or wound infection were not significantly different by season (P > .05).

Conclusion

Our findings indicate no differences in complications and PROMs at 1 year in patients undergoing THA during 4 distinct seasons. Notably, patients had functional differences at the second follow-up visit, suggesting variation in short-term recovery. Patients could be counseled that they have similar rates of complications and postoperative recovery regardless of season.

Rural-Urban Differences in Hospital and Patient-Reported Outcomes Following Total Hip Arthroplasty

Background

Rural patients have unique health-care factors influencing outcomes of arthroplasty, hypothetically putting these patients at increased risk for complications following total joint arthroplasty. The aim of this study is to better understand differences in patient outcomes and satisfaction between rural and urban patients receiving care in an urban setting and to provide more equitable care.

Methods

A retrospective chart review was performed on patients undergoing primary total hip arthroplasty at a single large academic center between January 2013 and August 2020. Demographic, operative, and hospital outcomes were obtained from the institutional electronic medical record. Rurality was determined by rural-urban code (RUC) classifications by zip code with RUC codes 1-3 defined as urban and RUC 4-10 defined as rural.

Results

Patients from urban areas were more likely to visit the emergency department within 30 days postoperatively (P = .006) and be readmitted within 90 days (P < .001). However, unplanned (P < .001) admissions were higher in the rural group. There was no statistical difference in postoperative complications (P = .4). At 6 months, rural patients had higher patient-reported outcome measures (PROMs) including Hip Disability and Osteoarthritis Outcome Score total (P = .05), Hip Disability and Osteoarthritis Outcome Score interval (P = .05), self-reported functional improvement (P < .05), improvements in pain (P < .05), and that the surgery met expectations (P < .05). However, these values did not reach minimal clinically important difference.

Conclusions

There may be differences in emergency department visits, readmissions, and PROMs in rural vs urban populations undergoing total hip arthroplasty in an urban setting. Patient access to care and attitudes of rural patients toward health care may underlie these findings. Understanding differences in PROMs, satisfaction, and hospital-based outcomes based on rurality is essential to provide equitable arthroplasty care.

Desmoid fibromatosis following surgical resection of spinal meningioma

A 42-year-old female patient with a history of cervicothoracic junction meningioma World Health Organization grade I, resected in early 2011, was admitted to the hospital with intractable headache and lower extremity weakness. Magnetic resonance imaging (MRI) showed an epidural mass compressing the spinal cord at the prior surgical site, which was interpreted as recurrent meningioma. Following surgical resection, histopathological analysis revealed desmoid fibromatosis (desmoid tumor). In retrospect, dynamic contrast-enhanced magnetic resonance imaging performed prior to surgery should have allowed for prospective exclusion of meningioma as the recurrent mass and suggested an alternative diagnosis such as post-traumatic desmoid fibromatosis or the need for biopsy to confirm diagnosis.

Calcified leiomyoma of the deltoid: pathophysiology and imaging review

Leiomyomas are benign tumors of smooth muscle cells. Leiomyomas of somatic soft tissue are a specific class of leiomyoma believed to arise from the smooth muscle cells found in the walls of blood vessels and represent less than 4% of benign, somatic soft tissue tumors. Of the somatic soft tissue tumors, approximately one-third will become calcified. We report an intramuscular, calcified leiomyoma arising from the left deltoid of a 47-year-old Caucasian male. To the best of the authors' knowledge, this is the first reported case of a calcified, intramuscular leiomyoma of the deltoid. Imaging studies and patient presentation were initially suggestive of tumoral calcinosis or myositis ossificans. It was not until pathologic examination that the correct diagnosis of the calcified leiomyoma was made. Leiomyoma should be included in the differential diagnosis of calcified soft tissue masses. If excised with adequate margins, recurrence is unlikely.
