A survey of exposure to the use of Xiaflex for the treatment of Peyronie's disease among United States urology residency programs.

Xiaflex® (collagenase clostridium histolyticum) is a Food and Drug Administration-approved treatment for patients with Peyronie's disease. Despite its approval and implementation, there is concern that urologists in training are offered minimal exposure to its use. Thus, the purpose of this study was to evaluate the exposure of urology residents to Peyronie's disease and its management, particularly Xiaflex®. A Google Forms survey regarding the exposure of residents to Peyronie's disease and use of Xiaflex® was created and disseminated through email to urology programs. Overall, 47 institutional responses were received. At 45 institutions (95.7%), residents receive training in directly evaluating and caring for patients with Peyronie's disease. At 46 institutions (97.9%), residents receive training in observing and/or performing surgical procedures for Peyronie's disease. Residents at 31 institutions (66.0%) receive observational or procedural training for non-surgical management of Peyronie's disease, specifically Xiaflex®. Residents receive non-surgical training from an academic faculty who is fellowship trained in sexual medicine at 25 institutions and an academic faculty not trained in sexual medicine at six institutions. There exists a glaring disparity in residency exposure to Xiaflex®. Further research is warranted to elucidate how programs can provide residents with further exposure to the use of Xiaflex® in patients with Peyronie's disease.

Maxine Deborrah Hyde: First Female Graduate of Case Western Reserve University's Neurologic Surgery Residency Program and Second Black Female Neurosurgeon in the United States.

BACKGROUND: The historical diversity gap in the neurosurgical workforce persists to this day. Women, despite constituting over half of the yearly total of medical school graduates, comprise only 6% of certified practicing neurosurgeons in the United States. Furthermore, Black Americans make up under 4% of U.S. neurosurgeons, despite making up around 14% of the national population. The purpose of this account is to highlight the life and career of Dr. Maxine Deborrah Hyde and illustrate the importance and necessity of diversity and inclusivity in advancing the field of neurosurgery. Through this paper, we aspire to encourage the development of new diversity initiatives. METHODS: Original scientific and bibliographic materials of Hyde were examined, and an extensive analysis of her life was compiled. RESULTS: Despite growing up during the era of Jim Crow, Dr. Hyde persevered and became the valedictorian of Oak Park High School. As a first-generation college student at Tougaloo College, she later earned her MS from Cleveland State University. Dr. Hyde graduated with honors from Case Western Reserve University School of Medicine in 1977. Thereafter, she became the first female and first Black graduate of Case Western's neurosurgery residency and the second Black woman to receive certification from the American Board of Neurological Surgery. Later in life, Dr. Hyde established the Beacon of Hope Scholarship Foundation to assist disadvantaged students in overcoming educational barriers. CONCLUSIONS: Dr. Hyde was a trailblazer who overcame systematic barriers and paved the way for future generations of aspiring neurosurgeons.

Calcified spinal meningiomas: a systematic review of clinical characteristics, treatment strategies, and outcomes.

BACKGROUND: Calcified meningiomas involving the spine are rare but can pose significant surgical challenges. We systematically reviewed the literature on calcified spinal meningiomas. METHODS: PubMed, EMBASE, Web-of-Science, and Scopus databases were searched to include studies reporting clinical data of patients with calcified spinal meningioma. Included articles were analyzed for symptoms, imaging, spine level of the tumor, tumor location relative to the spinal cord, calcification status, treatment regimen, recurrence, progression-free survival, and outcomes. RESULTS: A total of 35 articles encompassing 94 patients were included. Most patients were female (90.4%), presenting with lower extremity weakness (44%) and/or lower extremity paresthesia (38.1%). Most calcified spinal meningiomas occurred in the thoracic spine (82%) and on the dorsal (33.3%) or ventral (27.2%) side relative to the spinal cord. Most tumors were intradural (87.2%). Histologically, most calcified spinal meningiomas were WHO grade I (97.4%) and psammomatous (50.7%). Most tumors demonstrated macroscopic calcification (48.9%). Most patients underwent gross total resection (91.5%) through a posterior approach (100%). Two patients (2.1%) received adjunctive radiotherapy. The most common treatment related complication was CSF leakage. Post-operatively, most patients demonstrated symptomatic improvement (75.5%) and 2 (2.1%) had local tumor recurrence. CONCLUSIONS: Calcified spinal meningiomas are uncommon but benign entities. These neoplasms tend to adhere to surrounding tissues and nerves and, thus, can be surgically challenging to remove. In most patients, safe gross total resection remains the standard of care, but accurate surgical planning is necessary to reduce the risks of postoperative complications.

Impact of obesity on complications and surgical outcomes after adult degenerative scoliosis spine surgery.

OBJECTIVE: To compare perioperative outcomes of obese versus non-obese adult patients who underwent degenerative scoliosis spine surgery. METHODS: 235 patients who underwent thoracolumbar adult spinal deformity (ASD) surgery (≥4 levels) were identified and categorized into two cohorts based on their body mass indices (BMI): obese (BMI ≥30 kg/m2; n = 81) and non-obese (BMI <30 kg/m2; n = 154). Preoperative (demographics, co-morbidities, American Society of Anesthesiologists (ASA) score and modified frailty indices (mFI-5 and mFI-11)), intraoperative (estimated blood loss (EBL) and anesthesia duration), and postoperative (complication rates, Oswestry Disability Index (ODI) scores, discharge destination, readmission rates, and survival) characteristics were analyzed by student's t, chi-squared, and Mann-Whitney U tests. RESULTS: Obese patients were more likely to be Black/African-American (p < 0.05, OR:4.11, 95% CI:1.20-14.10), diabetic (p < 0.05, OR:10.18, 95% CI:4.38-23.68) and had higher ASA (p < .01) and psoas muscle indices (p < 0.0001). Furthermore, they had greater pre- and post-operative ODI scores (p < 0.05) with elevated mFI-5 (p < 0.0001) and mFI-11 (p < 0.01). Intraoperatively, obese patients were under anesthesia for longer time periods (p < 0.05) with higher EBL (p < 0.05). Postoperatively, while they were more likely to have complications (OR:1.77, 95% CI:1.01 - 3.08), had increased postop days to initiate walking (p < .05) and were less likely to be discharged home (OR:0.55, 95% CI:0.31-0.99), no differences were found in change in ODI scores or readmission rates between the two cohorts. CONCLUSIONS: Obesity increases pre-operative risk factors including ASA, frailty and co-morbidities leading to longer operations, increased EBL, higher complications and decreased discharge to home. Pre-operative assessment and systematic measures should be taken to improve peri-operative outcomes.
