Current state of musculoskeletal fellowship program directors and future directions.

OBJECTIVE: To better understand the current state of musculoskeletal fellowship program directors and identify opportunities for formal training that could increase job satisfaction, provide a broader knowledge base for mentoring/advising trainees and increase diversity in musculoskeletal radiology. MATERIALS AND METHODS: Eighty-one fellowship program directors who signed the Fellowship Match Memorandum of Understanding with the Society of Skeletal Radiology were sent a survey with questions about demographics, career, background, and training both for musculoskeletal radiology and for the fellowship director role. RESULTS: A 57/81 (70%) of program directors responded, representing 27 different states with a range of 1-9 fellowship positions. Nearly half are in their forties (48%) with most identifying as White (67%) followed by Asian (30%). The majority are male (72%) with over half (60%) remaining at the institution where they completed prior training. Over half plan to change roles within 5 years and do not feel adequately compensated. Top qualities/skills identified as important for the role include effective communication, being approachable, and clinical excellence. Other than clinical excellence, most do not report formal training in skills identified as important for the role. CONCLUSIONS: Given the high amount of interaction with trainees, program directors play a key role in the future of our subspecialty. The low diversity among this group, the lack of formal training, and the fact that most do not feel adequately compensated could limit mentorship and recruitment. Program directors identified effective communication, organizational/planning skills, and conflict resolution as the top skills they would benefit from formal training.

Anaplastic plasmacytoma: a rare tumor presenting as a pathological fracture in a younger adult.

Solitary plasmacytoma is the rarest type of plasma cell neoplasm, and the anaplastic form is even more uncommon. Plasmacytoma most commonly originates in bone and predominantly affects older patients. We describe the case of a 35-year-old woman with solitary osseous anaplastic plasmacytoma that presented initially with a pathological fracture following minor trauma. The patient was immunocompetent and had no predisposing conditions for a plasma cell tumor. Left lower extremity radiographs revealed an oblique fracture of the distal femur, and CT imaging indicated a primary osseous lesion at the fracture site. MRI confirmed the diagnosis of pathological fracture. Initial surgical pathology of the lesion was concerning because it could have been an osteosarcoma. Further immunostaining demonstrated CD138 positivity and kappa light chain restriction, confirming the diagnosis of plasmacytoma. In addition, the presence of marked anaplastic cellular changes confirmed the anaplastic variant. Further workup showed no evidence of multiple myeloma. This case is unusual given the age and gender of the patient. Awareness of the anaplastic variant of plasmacytoma is important to avoid erroneous diagnoses.

Purtscher's retinopathy associated with acute pancreatitis.

PURPOSE: Purtscher's retinopathy is a rare condition that is associated with complement-activating systemic diseases such as acute pancreatitis. After pancreatic injury or inflammation, proteases such as trypsin activate the complement system and can potentially cause coagulation and leukoembolization of retinal precapillary arterioles. Specifically, intermediate-sized emboli are sufficiently small enough to pass through larger arteries yet large enough to remain lodged in precapillary arterioles and cause the clinical appearance of Purtscher's retinopathy. This pathology may present with optic nerve edema, impaired visual acuity, visual field loss, as well as retinal findings such as cotton-wool spots, retinal hemorrhage, artery attenuation, venous dilation, and Purtscher flecken. CASE REPORT: A 57-year-old white man presented with an acute onset of visual field scotomas and decreased visual acuity 1 week after being hospitalized for acute pancreatitis. The retinal examination revealed multiple regions of discrete retinal whitening surrounding the disk, extending through the macula bilaterally, as well as bilateral optic nerve hemorrhages. The patient identified paracentral bilateral visual field defects on Amsler Grid testing, which was confirmed with subsequent Humphrey visual field analysis. Although the patient presented with an atypical underlying etiology, he exhibited classic retinal findings for Purtscher's retinopathy. After 2 months, best corrected visual acuity improved and the retinal whitening was nearly resolved; however, bilateral paracentral visual field defects remained. CONCLUSIONS: Purtscher's retinopathy has a distinctive clinical presentation and is typically associated with thoracic trauma but may be a sequela of nontraumatic systemic disease such as acute pancreatitis. Patients diagnosed with acute pancreatitis should have an eye examination to rule out Purtscher's retinopathy. Although visual improvement is possible, patients should be educated that there may be permanent ocular sequelae.

Five Years of the Musculoskeletal Radiology Fellowship Match: Trends and Perspectives.

RATIONALE AND OBJECTIVES: The 2023 Match marks 5 years since the Musculoskeletal (MSK) Radiology Fellowship Match first took place in June 2019. The objective of this study is to analyze trends in the MSK Match over its 5-year course. MATERIALS AND METHODS: Data from the National Resident Matching Program were evaluated for the number of applicants, medical school type of matched applicants, number of programs, and number of positions. Programs were grouped according to geographic region, program size, and ACGME accreditation status. These data were plotted to look for trends over time and by program characteristics. RESULTS: There has been little variation in the number of eligible programs registering for the Match (range 80-83). The number of available positions has had a wider variation (range 204-218), and the number of applicants preferring MSK has varied from 156 to 178. The gap between positions and applicants has resulted in a percentage of positions filled that has ranged from 70.9% to 82.4%. Program size is positively correlated with Match rates, with 100% of programs with five or more positions filling ≥ 50% in 4 out of 5 years. CONCLUSION: The variable numbers of fellowship positions and applicants have resulted in variable success of the Match by all metrics. Maintaining or increasing the number of applicants is the most critical factor for ongoing Match success.

Increasing Utilization and Improving Documentation in a Radiology Critical Alert System.

Effective communication of critical imaging findings is an important patient safety issue. Despite an increase in exam volumes, our institution saw a decrease in the number of alerts sent through our critical alert system, indicating that critical findings were not being communicated. The purpose of our interventions was to increase the number of critical alerts, while also improving documentation and improving our provider database. We used a program of education for our radiologists and systematic reinforcement to increase the usage of our critical alert system. We also implemented a new time-stamp macro in our dictation system to improve documentation of emergency alerts, and engaged with other departments to improve the contact information in our provider database. Our interventions led to an increase in the monthly number of critical alerts, most notably for findings that require clinical or imaging follow-up (17 alerts per month). There was also a steady improvement in documentation (96.9% compliance), along with an increase in the number of alerts to providers with current contact information (0.5% per month). Our efforts show that educational and collaborative efforts can result in improved communication of radiologic critical results.

Chondroblastoma-like Osteosarcoma.

CONTEXT.­: Chondroblastoma-like osteosarcoma is an exceedingly rare variant of osteosarcoma, with 22 cases reported in the English-language literature. The tumor is slightly more common in males, with a broad age range (from childhood to elderly). The most commonly involved bones are the metatarsus and tibia, followed by the femur. Most tumors have malignant or worrisome radiographic findings. Prognosis is variable, depending on the presence or absence of lung metastases, local recurrence, and probably tumor location. Histologically, chondroblastoma-like osteosarcoma is characterized by monotonous, minimally to moderately atypical rounded cells with ovoid nuclei resembling chondroblastoma, and abnormal osteoid deposition with destruction of the bone. OBJECTIVE.­: To review the clinical, radiographic, and histopathologic features of chondroblastoma-like osteosarcoma. DATA SOURCES.­: PubMed-published chondroblastoma-like osteosarcoma cases in the English-language literature. CONCLUSIONS.­: Although exceedingly rare, chondroblastoma-like osteosarcoma should be considered in the differential diagnosis of chondroblastoma, especially in the presence of radiologic findings suggestive of an aggressive lesion.

Umbilical Cord Teratomas Associated With Congenital Malformations.

CONTEXT.­: Congenital mature teratomas of the umbilical cord are extremely rare and pose a challenge in prenatal diagnosis. Mature teratomas are defined as tumors composed of mature tissues derived from more than 1 germ cell layer. The tumor often shows solid and cystic components, which adds to the difficulty of prenatal diagnosis. Although benign, mature teratomas of the umbilical cord are commonly associated with congenital malformations of the fetus with variable severity and rarely, with chromosomal abnormalities. OBJECTIVE.­: To review the clinical, radiologic, gross, and histologic features of umbilical cord teratoma; its differential diagnosis; and to emphasize the increased risk of associated congenital malformations. DATA SOURCES.­: Umbilical cord teratoma cases published in the literature. CONCLUSIONS.­: Umbilical cord teratomas are difficult to diagnose by imaging studies alone and require histopathologic examination for diagnosis. Given the increased risk of associated anomalies and malformations, the finding of umbilical cord teratoma should trigger a detailed and comprehensive evaluation of the neonate for additional abnormalities.

Reconstruction of speech from whispers.

This paper investigates a method for the real-time reconstruction of normal speech from whispers. This system could be used by aphonic individuals as a voice prosthesis. It could also provide improved verbal communication when normal speech is not appropriate. The normal speech is synthesized using the mixed excitation linear prediction model. Differences between whispered and phonated speech are discussed and methods for estimating the parameters of this model from whispered speech for real-time synthesis are proposed. This includes smoothing the noisy linear prediction spectra, modifying the formants, and synthesizing of the excitation signal. Trade-offs between computational complexity, delay, and accuracy of different methods are discussed.

Atypical presentation and review of the ICE syndrome.

BACKGROUND: The different variants of the iridocorneal endothelial (ICE) syndrome were separately described in the early to mid-1900's and were eventually linked to a common etiology of an abnormal corneal endothelium. The ICE syndrome typically manifests in early to middle adulthood, usually occurs in women, and is almost always unilateral. Management of patients with any variant of the ICE syndrome challenges even the best clinicians. CASE REPORT: We present a 52-year-old patient with Chandler's syndrome. Our patient shared many of the classic characteristics of Chandler's syndrome, including peripheral anterior synechiae and corneal edema, with one unusual aspect--the patient was male. Details regarding the subsets of the ICE syndrome, differential diagnosis, and current understanding of the pathophysiology are also reviewed. CONCLUSION: The ICE syndrome is a progressive anterior segment disease that is quite difficult to manage. Corneal edema, increased IOP, and glaucoma are all sequelae of these conditions and, even in the best hands, are extremely challenging to manage. Today, nearly 100 years after Harms described the first patient with an ICE syndrome, we still do not know the exact mechanism for the corneal endothelial changes. Many investigations have been made into the causative agent or stimulus for abnormal endothelial growth in the ICE syndrome. No definitive proof has been established, but a relationship may exist with the Herpes Simplex and Epstein-Barr viruses. Further investigation is needed to determine the most-appropriate treatment and management of the ICE syndrome.

Nonclassic retinitis pigmentosa: A challenging clinical diagnosis solved by pedigree analysis and electrodiagnostic testing.

PURPOSE: The aim of this study was to describe a case of nonclassic retinitis pigmentosa, to highlight ancillary testing tools for proper diagnosis, and to differentiate between common hereditary fundus dystrophies. METHODS: Methods used in this study included complete ophthalmologic evaluation, optical coherence tomography, visual field testing, pedigree analysis, and electrodiagnostic testing. RESULTS: Reduced vision and photopsia were the initial complaints of a patient who had an overall normal ocular appearance. However, a strong family history of retinitis pigmentosa and depressed scotopic and photopic electroretinograms confirmed the diagnosis of autosomal dominant retinitis pigmentosa. CONCLUSION: In cases of atypical-appearing retinitis pigmentosa, both pedigree analysis and electrodiagnostic testing are fundamental in correct diagnosis of this multifaceted hereditary fundus disorder.

Advanced visual field loss secondary to optic nerve head drusen: case report and literature review.

BACKGROUND: Optic nerve head drusen (ONHD) is a relatively uncommon condition that results from calcific degeneration of axons within the optic nerve. The abnormal drusen bodies can enlarge, compressing normal nerve structures, and ultimately may result in vision loss. Drusen often are discovered through clinical evaluation with a dilated funduscopic examination. Ancillary testing, including computed tomographic (CT) imaging, B-scan ultrasonography, autofluorescence imaging, nerve fiber layer imaging, and threshold visual field evaluation are helpful to confirm the existence of ONHD and to evaluate for progression of this condition. CASE REPORT: This case report discusses the clinical presentation of a patient with advanced visual field loss from ONHD and the ancillary testing used to confirm the diagnosis. A complete review of literature on ONHD is discussed. CONCLUSIONS: Currently, there is no cure or direct treatment for progressive vision loss or complications that may develop from ONHD. Useful diagnostic tools include serial automated threshold visual fields, nerve fiber layer analysis, and fundus photography. It is suggested that ocular hypotensive agents be used to lower intraocular pressure prophylactically to prevent further nerve fiber layer and optic nerve damage.
