RESUMEN
In recent decades, opioid overdoses have increased dramatically in the United States and peer countries. Given this, emergency medicine physicians have become adept in reversing and managing complications of acute overdose. However, many remain unfamiliar with initiating medication for opioid use disorder such as buprenorphine, a high-affinity partial opioid agonist. Emergency department-based buprenorphine initiation is supported by a significant body of literature demonstrating a marked reduction in mortality in addition to increased engagement in care. Buprenorphine initiation is also safe, given both the pharmacologic properties of buprenorphine that reduce the risk of diversion or recreational use, and previously published literature demonstrating low rates of respiratory depression, sedation, and precipitated withdrawal. Further, barriers to emergency department-based initiation have been reduced in recent years, with publicly available dosing and up-titration schedules, numerous publications overviewing best practices for managing precipitated withdrawal, and removal of USA policies previously restricting patient access and provider prescribing, with the removal of the X-waiver via the Medication Access and Training Expansion Act. Despite reductions in barriers, buprenorphine initiation in the emergency room remains underutilized. Poor uptake has been attributed to numerous individual and systemic barriers, including inadequate education, provider stigma, and insufficient access to outpatient follow-up care. The following practice innovation aims to summarize previously published evidence-based best practices and provide an accessible, user-friendly initiation guide to increase emergency physician comfortability with buprenorphine initiation going forward.
RESUMEN
Nutmeg intoxication is an uncommon precipitant of hyperactive delirium with severe agitation (HDSA) with anticholinergic properties that require a high index of suspicion for diagnosis. We present a case of a young adult who presented to the emergency department (ED) with HDSA. The patient was intubated and transferred to the medical intensive care unit (MICU) due to increasing safety threats unresponsive to multimodal de-escalation. He ultimately self-extubated, reported excessive nutmeg ingestion, and was discharged home after a short period of observation. Improved detection and streamlined management pathways for nutmeg intoxication will minimize unnecessary invasive procedures and costs to the healthcare system.
RESUMEN
A female in her early 40s taking buspirone, quetiapine, and daily kratom presented to the emergency department two days after starting a course of Paxlovid for a mild COVID-19 infection with diffuse tremors, ocular clonus, diaphoresis, and confusion consistent with serotonin syndrome (SS). The patient was treated with oral lorazepam, and her symptoms significantly improved within one hour without the need for additional dosing. To our knowledge, this is the first reported case of SS in a COVID-19-positive patient who was prescribed Paxlovid. Clinicians should be mindful of the potential interactions of Paxlovid with serotonergic agents, and they should consider reducing the dose of these agents or selecting other therapeutics to treat COVID-19 infection in these patients.
RESUMEN
BACKGROUND: Patients intubated in the prehospital setting require quick and definitive confirmation of endotracheal (ET) tube placement upon arrival to the emergency department (ED). Direct and adjunct strategies exist, but each has limitations and there is no definitive gold standard. The utility of bronchoscopy in ED intubation has been studied, but scant literature exists on its use for ET tube confirmation. This study aims to assess effectiveness, ease and speed with which ET tube placement can be confirmed with disposable fiberoptic bronchoscopy. METHODS: Emergency medicine residents recruited from a 3-year urban residency program received 5 minutes of active learning on a simulation mannequin using a disposable, flexible Ambu aScope interfaced with a monitor. With residents blinded, the researcher randomly placed the ET tube in the trachea, esophagus or right mainstem. Residents identified ET tube position by threading the bronchoscope through the tube and viewing distal anatomy. Each resident underwent 4 trials. Accuracy, speed and perceptions of difficulty were measured. RESULTS: Residents accurately identified the location of the ET tube in 88 out of 92 trials (95.7%). The median time-to-guess was 7.0 seconds, IQR (5.0-10.0). Average perceived difficulty was 1.6 on a scale from 1-5 (1 being very easy and 5 being very difficult). No tubes were damaged or dislodged. CONCLUSION: While simulation cannot completely replicate the live experience, fiberoptic bronchoscopy appears to be a quick and accurate method for ET tube confirmation. Further studies directly comparing this novel approach to established practices on actual patients are warranted.
RESUMEN
Hepatocellular carcinoma (HCC) represents a unique challenge for physicians and patients. There is no definitively curative treatment. Rather, many treatment and management modalities exist with differing advantages and disadvantages. Both current guidelines and individual patient concerns must be taken into account in order to properly manage HCC. In addition, quality of life issues are particularly complex in patients with HCC and these concerns must also be factored into treatment strategies. Thus, considering all the options and their various pros and cons can quickly become complex for both clinicians and patients. In this review, we systematically discuss the current treatment modalities available for HCC, detailing relevant clinical data, risks and rewards and overall outcomes for each approach. Surgical options discussed include resection, transplantation and ablation. We also discuss the radiation modalities: conformal radiotherapy, yttrium 90 microspheres and proton and heavy ion radiotherapy. The biologic agent Sorafenib is discussed as a promising new approach, and recent clinical trials are reviewed. We then detail currently described molecular pathways implicated in the initiation and progression of HCC, and we explore the potential of each pathway as an avenue for drug exploitation. We hope this comprehensive and forward-looking review enables both clinicians and patients to understand various options and thereby make more informed decisions regarding this disease.

BACKGROUND: The most common clinical presentation of thoracic outlet syndrome stems from compression of the lower trunk of the brachial plexus or ulnar nerve. A plethora of anatomical variations have been implicated in the cause of thoracic outlet syndrome. Roos' identification and classification of scalene muscle and fibrous bands have added an additional dimension to understanding its cause and subsequent treatment. Understanding the anatomy and relationship of this band with the lower trunk of the brachial plexus is of paramount importance. METHODS: As part of the authors' long-term study of the type 3 band in relation to the brachial plexus, 70 embalmed cadavers were dissected to yield 100 first thoracic ribs. Fibrous bands, when present, were studied in relation to the brachial plexus. RESULTS: A fibrous band consistent with Roos' type 3 was identified and found to occur in 35 percent of first ribs and 41 percent of cadavers. The mean size was 3.45 × 0.27 cm. Origins and insertions are described. Contrary to Roos' own description, however, the authors observed that Roos' type 3 band was anterior to the T1 nerve root, creating a tunnel through which the T1 nerve root must pass before joining the C8 nerve root. CONCLUSIONS: The authors believe that the type 3 band, when present, can create a tunnel that compresses the T1 nerve root against the first rib, potentially predisposing susceptible individuals to thoracic outlet syndrome. Clinical studies are needed to determine whether correlations between type 3 bands and thoracic outlet syndrome exist.

BACKGROUND: Turnover flaps are often utilized as alternatives to more traditional flaps, especially in situations where traditional flap viability is limited. Most turnover flaps are currently used in the lower extremities. METHODS: This study examined the senior author's use of the turnover flap in 103 cases between 1987 and 2004. Postoperative follow-up ranged from 3 months to 10 years, with an average follow-up of 9 months. RESULTS: The majority (n = 90) of the cases involved the lower extremities and carried high success rates; there were 72 successful operations (complete graft take), 10 partial flap losses (partial graft take that could be treated postoperatively without surgery), and eight complete flap losses (no graft take and the necessity of additional surgery). Three of the partial flap losses and two of the complete flap losses involved patients with end-stage vascular disease. End-stage vascular disease cases represented 20.0 percent of the lower extremity cases and carried a significantly higher percentage of partial or complete flap loss (27.8 percent). These circumstances were examined in detail; the authors found that the turnover flap provided improved outcome to such end-stage patients who otherwise would have undergone amputation. In 13 cases, turnover flaps were utilized in nontraditional regions, such as the chest wall, abdominal wall, head and neck region, and upper extremities, with a high degree of success (zero partial or complete flap losses). These approaches are discussed in detail. The surgical approach is examined with recommendations regarding preferred wound size and type and overall flap design. CONCLUSIONS: This study indicates that turnover flaps are effective and useful as an alternative and, in some cases, primary procedure. In addition, the results serve to expand the present scope of the turnover flap by examining nontraditional regions in which the flap was highly successful. The authors believe the turnover flap should be given higher priority as a reconstructive option, but more research is needed to explain the sources of blood supply in these flaps.

BACKGROUND: The purpose of this article is to report the increased incidence of community-acquired methicillin-resistant S. aureus in hand infections at an urban medical center. METHODS: The authors performed a retrospective review of all patients with hand infections over a 21-month period, and all patients with culture-positive methicillin-resistant S. aureus were identified. Cases determined to be nosocomial were excluded. The study period was divided into three 7-month periods. RESULTS: A total of 343 hand infections were treated over a 21-month period. Eighty-nine patients (26 percent) with culture positive methicillin-resistant S. aureus were identified; of these, 75 were determined to be community-acquired methicillin-resistant S. aureus patients. Statistical analysis was performed using the Fisher's exact test (p < 0.0001), the chi-square test for equal proportions, the Cochran-Armitage trend test, and two-way analysis of variance. The demographics of the patients were compared using two-way analysis of variance, and patients were found to be similar in all three time periods with respect to mean age and sex. The incidence of community-acquired methicillin-resistant S. aureus increased to 40 percent during the last 7-month period compared with 14 percent during the first two periods. Overall, the incidence of methicillin-resistant S. aureus increased to 47 percent during the last 7 months compared with 16 percent and 17 percent in the first two 7-month periods, respectively. Based on their treatment approach and literature review, the authors have developed an algorithm to treat community-acquired methicillin-resistant S. aureus hand infections. CONCLUSIONS: The authors' findings at Temple University Hospital may help to alert health care providers to take necessary steps to control the spread of methicillin-resistant S. aureus in the community and in the inpatient setting. Cultures should be carefully followed and infections should be treated with appropriate antibiotics.

OBJECTIVE: The infection of an aortic prosthetic graft presents a difficult challenge for surgeons. Conservative treatments such as debridement and antibiotic irrigation routinely fail, and patient survival rates are low. Literature has indicated that flap procedures often provide better treatment. In the present article, we report our experience utilizing pectoralis major muscle flaps, occasionally coupled with latissimus dorsi, rectus abdominis, and/or serratus anterior flaps, to wrap infected grafts and fill dead space. PATIENTS: Between 1990 and 2004, 10 patients were brought to our attention with infections of prosthetic grafts of the great vessels (7 men and 3 women; mean age, 53 years). Infections in nine patients involved an ascending aortic graft, while one patient had an infected pulmonary artery graft. DESIGN: Following diagnosis and exploration, an initial debridement is performed, followed by 48 h of antibiotic irrigation. A definitive muscle flap procedure is then utilized to fill dead space and clear the infection, followed by an appropriate antibiotic regimen. RESULTS: The infections in all 10 patients were cleared using the muscle flap procedure. Two patients required a tapered-dose regimen of oral steroids, one of whom also required a secondary flap procedure due to the advanced stage of infection. Two other patients later died due to unrelated complications; however, autopsies revealed that operative sites had healed successfully. Patients were followed up for a period of 2 months to 2 years, and recurrence was not found. CONCLUSIONS: Our outcomes suggest that muscle flap procedures, specifically utilizing the pectoralis major and regional muscles, should be kept in mind in the management of life-threatening infections of aortic grafts. Due to the limited number of patients in this study, we feel more research with a larger volume of cases is warranted.

Closure of thoracolumbar wounds and vertebral osteomyelitis after scoliosis surgery often proves difficult due to tautness and lack of usable tissue, and the resulting dead space containing metallic fixation devices is predisposed to infections and complications. The authors present their experience with 33 patients in whom massive thoracolumbar wounds and vertebral osteomyelitis developed following scoliosis surgery. Postoperative infection, due to the lack of vascularized tissue and presence of metallic hardware near the wound, is common and extremely counterproductive; within these cavernous wounds lie infected vertebrae, metallic hardware, and bone graft. The use of a modified and extended latissimus dorsi myocutaneous flap to close and supply blood to wounds in the lower thoracic and thoracolumbar areas is described. This surgical approach, predicated on effective débridement along with reconstruction by transposition of vascularized tissue, allows the wound to close and drastically decreases the risk of postoperative infection. Furthermore, for wounds already infected, the procedure allows for closure and increased blood supply to the area, thus giving the wound a much greater ability to heal. For wounds involving the lumbosacral area, the authors combine this with a transposed gluteus maximus muscle flap to obtain coverage over the caudal extent of the wound. In this study, all flaps accomplished their intended purpose: to secure the healing of once-infected wounds and to allow preservation of orthopedic instrumentation and bone graft. Follow-up revealed no flap losses, pseudarthroses, or loss of orthopedic instrumentation in the study group.
