AbstractMisdiagnosis of myelopathies is common and can lead to irreversible disability when diagnosis- and disease-specific treatments are delayed. Therefore, quickly determining the etiology of myelopathy is crucial. Clinical evaluation and MRI spine are paramount in establishing the correct diagnosis and subsequently an appropriate treatment plan. Herein, we review an approach to myelopathy diagnosis focused on the time course of neurologic symptom progression and neuroimaging pearls, and apply them to a variety of inflammatory, structural, and vascular myelopathy cases.

AbstractSeptic pulmonary embolism (SPE) is a rare clinical entity that is distinct from the classic and more common non-septic thrombotic pulmonary embolism. SPE should be suspected in patients with a systemic acute inflammatory reaction or sepsis who develop signs and symptoms of pulmonary involvement. The diagnosis of SPE depends on the specific radiologic finding of multiple, peripheral, nodular, possibly cavitated lesions. SPE should prompt an immediate search for the primary source of infection; typically, right-sided infective endocarditis, cardiac implantable electronic devices, and septic thrombophlebitis as a complication of bone, skin, and soft tissue infection including Lemierre's syndrome, indwelling catheters, or direct inoculation via injection drug use. Invasive treatment of the infection source may be necessary; in thrombophlebitis, the efficacy and safety of anticoagulation remain undefined. Blood cultures may be negative, particularly among patients with recent antibiotic exposure, and broad-spectrum antimicrobial therapy should be considered. The in-hospital mortality of SPE ranges up to 20% in published case series. While trends in the incidence of SPE are unknown, the opioid epidemic, the growing use of cardiac implantable electronic devices worldwide, and the reported increase in cases of septic thrombophlebitis may be leading to an escalation in SPE cases. We provide a contemporary profile of SPE and propose a clinical management algorithm in patients with suspected or confirmed SPE.

AbstractDespite being relatively uncommon in the general population, thumb amputations cause severe disability. More than 3,300 thumb amputations occurred in the United States. The thumb makes up around 40% of the function of the hand. Therefore, losing it would result in significant medical, hospital, and societal costs. Thumb reconstruction surgery's primary goal is to restore grip strength, including the range of motion, fine and tripod pinch, power grasp, strength, and sensibility, while secondary goals include restoring hand aesthetics. In cases of thumb replantation, like-for-like replacement is possible; however, when thumb replantation is not possible, great toe-to-hand transplantation is the best available reconstruction. When compared with other reconstructive options such as osteoplastic thumb reconstruction, pollicization, second toe transplantation, and the use of a thumb prosthesis, great toe transplantation provides superior function and aesthetics. For restoring pinch, sensitivity, strength, and aesthetics of the hand with well-tolerated donor site morbidity, toe to thumb transplantation is regarded as the gold standard.

AbstractThe scope of conditions managed by embolization, which was initially used for the treatment of hemorrhage and vascular malformations, is constantly expanding. Apart from oncologic indications, embolization is used to treat a wide range of benign pathology, including uterine fibroids and benign prostatic hyperplasia. While various particulate embolic agents are successfully used for benign embolization, there is growing evidence that unique properties of these may result in different outcomes. This article reviews available evidence comparing various particles used for uterine fibroid embolization and prostate artery embolization. In addition, we provide an overview of periprocedural pharmacology and protocols facilitating same-day discharge for these interventions.

Abstract Background and study aims Gastric outlet obstruction (GOO) is traditionally managed with surgical gastroenterostomy (surgical-GE) and enteral stenting (ES). Endoscopic ultrasound-guided gastroenterostomy (EUS-GE) is now a third option. Large studies assessing their relative risks and benefits with adequate follow-up are lacking. We conducted a comparative analysis of patients who underwent EUS-GE, ES, or surgical-GE for GOO. Patients and methods In this retrospective comparative cohort study, consecutive patients presenting with GOO who underwent EUS-GE, ES, or surgical-GE at two academic institutions were reviewed and independently cross-edited to ensure accurate reporting. The primary outcome was need for reintervention. Secondary outcomes were technical and clinical success, length of hospital stay (LOS), and adverse events (AEs). Results A total of 436 patients (232 EUS-GE, 131 ES, 73 surgical-GE) were included. The median duration of follow-up of the entire cohort was 185.5 days (interquartile range 55.25–454.25 days). The rate of reintervention in the EUS-GE group was lower than in the ES and surgical-GE groups (0.9 %, 12.2 %, and 13.7 %, P < 0.0001). Technical success was achieved in 98.3 %, 99.2 %, and 100 % (P = 0.58), and clinical success was achieved in 98.3 %, 91.6 %, and 90.4 % (P < 0.0001) in the EUS-GE, ES, and surgical-GE groups, respectively. The EUS-GE group had a shorter LOS (2 days vs. 3 days vs. 5 days, P < 0.0001) and a lower AE rate than the ES and surgical-GE groups (8.6 % vs. 38.9 % vs. 27.4 %, P < 0.0001). Conclusion This large cohort study demonstrates the safety and palliation durability of EUS-GE as an alternative strategy for GOO palliation in select patients.

Abstract Background Scapholunate (SL) ligament injuries are rarely diagnosed in children. This study reports the outcomes of surgically treated SL ligament injuries in patients younger than 18 years. Methods A retrospective review was performed on 20 pediatric patients with SL ligament injuries. Records were reviewed for preoperative and postoperative radiographic data, intraoperative findings, classifications of interosseous ligament injury, and postoperative course. Results Thirteen girls and seven boys sustained SL injuries requiring operative intervention and were followed for an average of 26 months. Magnetic resonance imaging (MRI) was performed in 15 patients, which revealed an SL tear in 7 patients. Arthroscopically, SL injuries were classified as Geissler grade III in 12 patients and grade IV in 5 patients. Based on the Mayo Wrist Score, nine patients had excellent or good results, while six demonstrated fair results. The mean wrist flexion–extension arc was 109 degrees, while the mean grip strength was 82% of the unaffected side. Patients treated >1 year following injury had significantly decreased grip strength and Mayo Wrist Score. Conclusion In this study, worse results were seen in children with a protracted course prior to treatment of an SL injury. A high index of suspicion is necessary to detect an SL injury in the younger age group and should be in the differential for those with persistent dorsal wrist pain, tenderness over the dorsal SL joint, and/or positive Watson's test. MRI may assist in diagnosis but is not definitive to rule out injury. Arthroscopy is valuable to determine the extent of injury.

Abstract Background Spanning bridge plates were first popularized for fixation of complex distal radius fractures. However, indications for their use have expanded including the surgical treatment algorithm for treating conditions such as Kienböck's disease. Traditionally, initial surgical treatment of Lichtman Stages II to III Kienböck's disease included lunate decompression, unloading, and revascularization procedures. The addition of a dorsal spanning bridge plate further facilitates lunate offloading and may improve bone revascularization. Case Description We report a complication of proximal carpal row dorsal subluxation secondary to dorsal spanning plate fixation in a patient with Stage IIIb Kienböck's disease. The patient had undergone wrist arthroscopy, lunate forage, radius core decompression, and spanning plate fixation. At 6 weeks after surgery, radiographic imaging demonstrated dorsal subluxation of the proximal carpal row that was corrected upon bridge plate removal. Serial radiographs during follow-up showed no further carpal subluxation without Kienböck's disease progression at 12 months postremoval of hardware. Patient remains pain free and has returned to elite level sport. Literature Review To our knowledge no previous cases of proximal carpal row subluxation with the use of dorsal bridge plate has been reported in the literature. Clinical Relevance Proximal row carpal subluxation can occur with dorsal bridge plate fixation.

Background Complete closure of large mucosal defects following colorectal endoscopic submucosal dissection (ESD) with through-the-scope (TTS) clips is oftentimes not possible. We aimed to report our early experience of using a novel TTS suturing system for the closure of large mucosal defects after colorectal ESD. Methods We performed a retrospective multicenter cohort study of consecutive patients who underwent attempted prophylactic defect closure using the TTS suturing system after colorectal ESD. The primary outcome was technical success in achieving complete defect closure, defined as a < 5 mm residual mucosal defect in the closure line using TTS suturing, with or without adjuvant TTS clips. Results 82 patients with a median defect size of 30 (interquartile range 25–40) mm were included. Technical success was achieved in 92.7 % (n = 76): TTS suturing only in 44 patients (53.7 %) and a combination of TTS suturing to approximate the widest segment followed by complete closure with TTS clips in 32 (39.0 %). Incomplete/partial closure, failure of appropriate TTS suture deployment, and the need for over-the-scope salvage closure methods were observed in 7.3 % (n = 6). One intraprocedural bleed, one delayed bleed, and three intraprocedural perforations were observed. There were no adverse events related to placement of the TTS suture. Conclusion The TTS suture system is an effective and safe tool for the closure of large mucosal defects after colorectal ESD and is an alternative when complete closure with TTS clips alone is not possible.

AbstractPosttraumatic headache (PTH) is the most common symptom following mild traumatic brain injury (mTBI) (also known as concussion). Migraine and PTH have similar phenotypes, and a migraine-like phenotype is common in PTH. The similarities between both headache types are intriguing and challenge a better understanding of the pathophysiological commonalities involved in migraine and PTH due to mTBI. Here, we review the PTH resting-state functional connectivity literature and compare it to migraine to assess overlap and differences in brain network function between both headache types. Migraine and PTH due to mTBI have overlapping and disease-specific widespread alterations of static and dynamic functional networks involved in pain processing as well as dysfunctional network connections between frontal regions and areas of pain modulation and pain inhibition. Although the PTH functional network literature is still limited, there is some evidence that dysregulation of the top-down pain control system underlies both migraine and PTH. However, disease-specific differences in the functional circuitry are observed as well, which may reflect unique differences in brain architecture and pathophysiology underlying both headache disorders.

AbstractAcute treatments for migraine and cluster headache are necessary to abort attacks, relieve pain and associated symptoms, and restore an individual's ability to function. Acute headache treatments consist of a variety of medication and nonmedication options. In this article, we discuss the approach to acute treatment of migraine and cluster headache. We summarize the level of evidence to support each acute medication class according to recent systematic reviews and meta-analyses, as well as guideline recommendations from the American Headache Society, American Academy of Neurology, and European Federation of Neurological Society.
