RESUMEN
BACKGROUND: Emergency physicians commonly perform ultrasound-assisted abdominal paracentesis, using point of care ultrasound (POCUS) to identify ascites and select a site for needle insertion. However, ultrasound-guided paracentesis has the benefit of real-time needle visualization during the entire procedure. Our objective was to characterize the performance of emergency physician-performed ultrasound-guided paracentesis using POCUS, their ability to achieve good in-plane needle visualization, and factors associated with procedural success. METHODS: A POCUS database was retrospectively reviewed for examinations where abdominal paracentesis was performed by an emergency physician at two academic urban emergency departments over a six-year period. Medical records were reviewed for demographics, presenting history, complications, and hospital course. Descriptive statistics were used to summarize the data. RESULTS: 131 patients were included in the final analysis. The success rate for ultrasound-guided paracentesis was 97.7% (84/86 [95% CI: 92-100%]) compared to 95.6% (43/45 [95% CI: 85-99%]) for ultrasound-assisted paracentesis (p=0.503). 58% (50/86) demonstrated good in-plane needle visualization; 17% (15/86) had partial or out-of-plane visualization; and 24% (21/86) did not demonstrate needle visibility on their saved POCUS images. All four procedural failures were performed by first- or second-year residents using a curvilinear transducer, while all procedures using a linear transducer were successful. The most common complications were ascites leak, infection at the site, and minor bleeding. CONCLUSIONS: Emergency physicians with training in real-time needle guidance with ultrasound were able to use POCUS to perform ultrasound-guided paracentesis in the emergency department with a high success rate and no fatal complications. Based on our experience, we recommend performing ultrasound-guided paracentesis using a linear transducer, with attention to identifying vessels near the procedure site and maintaining sterile technique.
RESUMEN
BACKGROUND: We aimed to evaluate the utility of point-of-care ultrasound (POCUS) in the assessment of hand infections that present to the emergency department (ED) and its impact on medical decision making and patient management. METHODS: We conducted a retrospective review of patients who presented to two urban academic EDs with clinical presentations concerning for skin and soft tissue infections (SSTI) of the hand between December 2015 and December 2021. Two trained POCUS fellowship physicians reviewed an ED POCUS database for POCUS examinations of the hand. We then reviewed patients' electronic health records (EHR) for demographic characteristics, history, physical examination findings, ED course, additional imaging studies, consultations, impact of POCUS on patient care and final disposition. RESULTS: We included a total of 50 cases (28 male, 22 female) in the final analysis. The most common presenting symptoms and exam findings were pain (100%), swelling (90%), and erythema (74%). The most common sonographic findings were edema (76%), soft tissue swelling (78%), and fluid surrounding the tendon (57%). POCUS was used in medical decision making 68% of the time (n=34), with the use of POCUS leading to changes in management 38% of the time (n=19). POCUS use led to early antibiotic use (11/19), early consultation (10/19), and led to the performance of a required procedure (8/19). The POCUS diagnosis was consistent with the discharge diagnosis of flexor tenosynovitis 8/12 times, abscess 12/16 times, and cellulitis 14/20 times. CONCLUSION: POCUS is beneficial for evaluating of hand infections that present to the ED and can be used as an important part of medical decision making to expedite patient care.
RESUMEN
Background: This retrospective review aimed to assess if open payments made by industry arthroplasty companies to physicians and hospital systems were significantly affected by implant type and geographic variation. Methods: Data was obtained from the Centers for Medicare and Medicaid Services (CMS) publicly available open payment datasets (2016-2019). Geographic locations were identified using regions as defined by the US Census Bureau. A linear regression was calculated to predict the open payment made based on the created variable region, the most used implant type (reverse vs anatomic, n > 30 to be included), and their hypothesized interaction. Results: A significant regression equation was found for the hypothesized interaction between implant and region, F(13,11â 186) = 3.446, P < .0001, with an R2 of 0.005. Within the regression, the implant type alone was not significantly related to the open payment (P = .070) but only became significant when paired with the region in the South (US$5807; P < .0001) and West (US$5638; P = .0012) compared to the Northeast. Discussion: Our multivariate linear regression model revealed that reverse total shoulder implants were associated with higher open payments, but only within the South and West regions. This indicates that the contributions made by industry arthroplasty companies are a function of both implant and region.
RESUMEN
INTRODUCTION: Wrong level surgery is a preventable event in spine surgery. The thoracic spine given its length and anatomical landmarks remains the most challenging spine section for accurate localization during surgery. Traditionally, counting the ribs with intraoperative fluoroscopy is the preferred method. The incidence of 11 ribs instead of the conventional 12 ribs is not examined in current scientific literature, even though the incidence of 11 ribs may have a substantial impact on spinal procedures and the outcomes. This is especially relevant if patients have a potential surgical pathology of their thoracic spine. In this case series we sought to investigate the prevalence of 11 ribs in a trauma population. METHODS: A retrospective review was conducted of patients presenting with thoracolumbar fractures at our Level I Trauma Center between 2017 and 2018. CT scans were obtained and analyzed by counting the number of ribs. RESULTS: Out of 234 patients who were consulted for thoraco-lumbar fractures by spine specialists, 8 patients had 11 ribs which results in a prevalence of 3.4 % in this population. Within these 8 patients, 5 were male (62.5 %). CONCLUSIONS: Spine surgeons should consider the possibility of numeric variation of ribs when evaluating thoracolumbar spine imaging. In a trauma population with spine fractures, the prevalence of 11 ribs is 3.4 %. Given the not insignificant prevalence of this variant in potentially surgical spine patients, the spine surgeon should remain vigilant of this anatomical variant.

BACKGROUND: Mucosa-associated lymphoid tissue (MALT) lymphomas are a subtype of non-Hodgkin lymphoma stemming from marginal zone B-cells. In this case report, we present two patients with an extremely rare localization of MALT lymphoma to the larynx. METHODS: Case 1 is of a 78-year-old male presenting with a six-month history of progressive hoarseness with a past medical history significant for marginal zone lymphoma of the right orbit. Diagnosis was confirmed with a biopsy for extranodal marginal zone B-cell lymphoma of MALT type. An FDG-PET scan was done but did not show any sign of FDG avid malignancy, including at the primary site. Case 2 is a 60-year-old female presenting with one year of worsening throat discomfort, intermittent cough, and dyspnea with exertion. Pathology confirmed a diagnosis of extranodal marginal zone B-cell lymphoma of MALT type. RESULTS: Case 1 was treated with low-dose radiation at 4 Gy delivered over two fractions of 2 Gy each. Upon completion of radiation treatment, he reported a resolution of his hoarseness and normalization of his voice. A four-month follow-up in May 2018 with flexible nasolaryngoscopy revealed a normal exam with fully mobile vocal folds bilaterally and no evidence of left false vocal fold submucosal mass. At seven months following treatment, the patient died unexpectedly of unknown causes. Case 2 was treated with radiation at 30 Gy in 15 fractions over the course of one month. Following completion of radiation therapy, she had improvement of her sore throat, nausea, dysphagia, dysgeusia, and dry mouth. At 21-month follow-up, she had no evidence of disease. CONCLUSION: This case report demonstrates that MALT lymphoma can present with much more benign and subtle symptoms. This highlights the importance of clinicians to keep broad differentials and consider MALT lymphomas in the setting of laryngeal masses.
