Trainee Insight into Pain Fellowship Programs: A Critical Evaluation of the Current Educational System by the APPD.

BACKGROUND: Since 1992, when the Accreditation Council of Graduate Medical Education (ACGME) acknowledged pain medicine as a subspecialty, the field has experienced significant growth in its number of programs, diversity of sponsoring specialties, treatment algorithms, and popularity among applicants. These shifts prompted changes to the educational model, overseen by program directors (PDs) and the ACGME. The pool of pain fellowship applicants also changed during that period. OBJECTIVES: This study aims to investigate trainees' reasons for applying to pain medicine fellowship programs as well as the applicants' specific expectations, interests, and motivations, thereby contributing to the remodeling and universal improvement of programs across the country. STUDY DESIGN: Online survey via SurveyMonkey. The online questionnaire targeted pain fellowship applicants in 2023 and current fellows in the US. METHODS: Our study was designed by board members of the Association of Pain Program Directors (APPD). The board disseminated a survey to those who applied to ACGME Pain Medicine fellowships in 2023 as well as to existing fellows. The survey was emailed to residency and fellowship PDs for dissemination to their trainees. The participants answered a 12-question survey on their reasons for pursuing pain medicine fellowships, expectations of and beyond those fellowships, and educational adjustments. RESULTS: There were 283 survey participants (80% applicants in residency training and 20% fellows). Participants ranked basic interventional procedures and a strong desire to learn advanced procedures as the most significant factors in pursuing a pain fellowship. Most trainees (70%) did not wish to pursue a 2-year fellowship, and 50% desired to go into private practice. LIMITATIONS: The relatively small number of respondents is a limitation that could introduce sampling error. Since most of the respondents were from the fields of physical medicine and rehabilitation (PM&R) and anesthesia, the use of convenience sampling reduced our ability to generalize the results to the wider community. Furthermore, approximately 80% of the trainees were residents, who might have had less experience in or knowledge of the survey's particulars than did the fellows. CONCLUSION: This survey demonstrated that procedural volume and diversity were important factors in trainees' decisions to apply to the field of pain medicine; however, extending the duration of a pain fellowship was not an option survey participants favored. Therefore, PDs and educational stakeholders in pain fellowship training need to develop creative strategies to maintain competitive applicants' interest while they adapt to our evolving field.

COVID-19 Proned Ventilation and Its Possible Association With Foot Drop: A Case Series.

The novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus causing the coronavirus disease 2019 (COVID-19) pandemic is known to lead to the complicated sequelae of severe acute respiratory distress syndrome. Proning has been used as an adjunctive treatment to improve oxygenation in both ventilated and non-ventilated patients. Although patients respond well to this strategy, complications from this arise as well. It is hypothesized that COVID-19 intensive care unit (ICU) proned ventilation is associated with new cases of foot drops or compressive unilateral ankle dorsiflexion weakness during the early 2020 COVID-19 pandemic. Five patients presented to an acute rehabilitation facility with unilateral ankle dorsiflexion weakness after ICU proned ventilation during the COVID-19 pandemic. Three patients were found to have primarily subacute left sensory-motor dysmyelinating common peroneal neuropathies located around the fibular head. Two patients were found to have primarily subacute sensory-motor dysmyelinating right-sided common peroneal neuropathies above the fibular head and distal to biceps femoris muscle. Compressive unilateral common peroneal neuropathies during the pandemic are possibly related to the impromptu, unconventional, and unfamiliar use of proned ventilation.

Mosaic fungal individuals have the potential to evolve within a single generation.

Although cells of mushroom-producing fungi typically contain paired haploid nuclei (n + n), most Armillaria gallica vegetative cells are uninucleate. As vegetative nuclei are produced by fusions of paired haploid nuclei, they are thought to be diploid (2n). Here we report finding haploid vegetative nuclei in A. gallica at multiple sites in southeastern Massachusetts, USA. Sequencing multiple clones of a single-copy gene isolated from single hyphal filaments revealed nuclear heterogeneity both among and within hyphae. Cytoplasmic bridges connected hyphae in field-collected and cultured samples, and we propose nuclear migration through bridges maintains this nuclear heterogeneity. Growth studies demonstrate among- and within-hypha phenotypic variation for growth in response to gallic acid, a plant-produced antifungal compound. The existence of both genetic and phenotypic variation within vegetative hyphae suggests that fungal individuals have the potential to evolve within a single generation in response to environmental variation over time and space.

Adverse Event Profiles of High Dose Botulinum Toxin Injections for Spasticity.

BACKGROUND: Botulinum toxin injections are effective in relieving focal spasticity resulting from upper motor neuron injuries. Doses approved in the United States for onabotulinumtoxinA and incobotulinumtoxinA are up to 400 units, yet higher doses are often used. OBJECTIVE: To determine differences in risk of adverse events when using higher (>600 units) as compared to lower doses within clinically applicable categories; the difference in adverse events between types of botulinum toxin-A, and any association of the injection of cervical muscles with increased risk for adverse events. DESIGN AND SETTING: Retrospective analysis of injections performed over a 3-year period at a freestanding rehabilitation hospital network. PARTICIPANTS: Persons with spasticity or dystonia undergoing ona- and/or incobotulinumtoxinA injections. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Adverse events for injections were divided into the three dose ranges (≤400 units, 401-600 units, or > 600 units). RESULTS: 889 injections in 342 patients met inclusion criteria with 65% ≤400 units, 21% 401-600 units, and 14% >600 units. Adverse events were not significantly increased in doses of 401-600 units relative to ≤400 units (OR 0.97, 95% CI 0.31, 2.98). Doses of toxin over 600 units were associated with significantly increased relative risk of adverse events (OR 2.98, 95% CI 1.12, 8.13). There were no significant differences between adverse event rates for onabotulinumtoxinA or incobotulinumtoxinA (P >.99). Inclusion of cervical muscles in isolation did significantly increase the risk of adverse events (OR 4.21, 95% CI 1.15, 15.46). CONCLUSION: Risk for adverse events were not significantly increased in doses of ona- and/or incobotulinumtoxinA up to 600 units, suggesting that the current 400 units upper bound of approved dose may need to be reexamined. Doses above 600 units were found to increase the rate of adverse effects and clinical benefit versus risk should be taken into account. LEVEL OF EVIDENCE: III.

Use of osteopathic manipulative treatment to manage recurrent bouts of singultus.

Singultus, or hiccups, are involuntary spasms of the diaphragm that in most cases are harmless and self-limited. Treatments are reserved for those cases that persist, and current options include pharmacotherapeutics, complementary methods (such as acupuncture), and osteopathic manipulative treatment. A 32-year-old woman with stiff person syndrome and concurrent aminoacidopathy in the setting of acute inpatient rehabilitation was experiencing daily bouts of singultus, ranging from 20-minute to 5-hour durations. Osteopathic manipulative treatment at the onset of spasm resulted in immediate cessation of and further suppression of singultus for approximately 12 to 24 hours. Overall, there was a noted reduction in singultus frequency, duration, and intensity, as well as better tolerance of physical and occupational therapy. The authors theorize that OMT could be a useful adjunct to, or replacement of, pharmacologic interventions for singultus, especially when pharmacologic therapies have failed.

Association of vitamin D deficiency, secondary hyperparathyroidism, and heterotopic ossification in spinal cord injury.

Our objective was to explore the relationship between low vitamin D, secondary hyperparathyroidism, and heterotopic ossification (HO) in patients with spinal cord injury (SCI). Ninety-six subjects with acute or chronic motor complete SCI participated. Levels of serum vitamin D25(OH), calcium, and intact parathyroid hormone (PTH) were collected, and information regarding nutritional patterns and fracture history was obtained from subjects. Evidence of current or previous HO was ascertained through chart review. Of the 96 subjects, 12 were found to have developed HO, 11 with serum vitamin D25(OH) between 5 and 17 ng/mL. Nine subjects exhibited secondary hyperparathyroidism in the range of 72 to 169 pg/mL. Only one subject demonstrated HO in the absence of low vitamin D. However, many subjects with low vitamin D (5-31 ng/mL) did not have hyperparathyroidism or HO. Statistical testing demonstrated a correlation between hyperparathyroidism and HO (p < 0.001) as well as hyperparathyroidism and vitamin D deficiency (<20 ng/mL). Direct correlation between HO and low vitamin D was not observed, but hyperparathyroidism may increase this risk. We believe that those patients who demonstrate low vitamin D and elevated PTH should be screened for HO in addition to beginning vitamin supplementation. Initiating early treatment of low vitamin D to restore therapeutic levels may prevent development of HO.
