RESUMEN
OBJECTIVES: Chemotherapy-induced peripheral neuropathy (CIPN) is a complication that may occur after treatment with various anticancer drugs. In refractory CIPN cases, spinal cord stimulation (SCS) has garnered increased attention. The use of gait analysis and psychophysical quantitative sensory testing (QST) as an objective measurement of CIPN-related damage has burgeoned; however, these changes have not been reported for patients with CIPN after SCS implantation using either burst or tonic stimulation. MATERIALS AND METHODS: This manuscript encompasses two parts: 1) a presentation of pain improvement in a series of patients who underwent tonic vs burst SCS for CIPN measured by gait and QST analysis and 2) a narrative review on gait and psychophysical QST outcomes between burst and tonic SCS stimulation pertaining to pain and the extrapolation to CIPN-related sequalae. RESULTS: In these cases, gait scores improved in both patients. Touch thresholds were higher before SCS whereas skin temperatures were lower at the dorsal foot, subtalus, and posterior calf. Sharpness detection was drastically improved after SCS. In the review, the patients aligned with pain relief, suggesting good response to interventional outcomes with SCS. QST outcomes, particularly touch, sharpness, heat, and cold stimuli, however, were not fully corroborated. Similarly to other non-CIPN SCS gait studies, both tonic and burst studies provided positive outcomes on spatiotemporal gait parameters, gait form, and standardized gait scales. CONCLUSION: We emphasize the use of different SCS waveforms as a therapy for CIPN management and the use of psychophysical testing as a measure for diagnosis and monitoring CIPN's progress in our case series and review.
RESUMEN
PURPOSE OF REVIEW: Spinal cord stimulation (SCS) is an increasingly utilized therapy for the treatment of neuropathic pain conditions. Though minimally invasive and reversable, there are several important device-related complications that physicians should be aware of before offering this therapy to patients. The aim of this review is to synthesize recent studies in device-related SCS complications pertaining to cylindrical lead implantation and to discuss etiologies, symptoms and presentations, diagnostic evaluation, clinical implications, and treatment options. RECENT FINDINGS: Device-related complications are more common than biologic complications. Device-related complications covered in this review include lead migration, lead fracture, lead disconnection, generator failure, loss of charge, generator flipping, hardware related pain, and paresthesia intolerance. The use of SCS continues to be an effective option for neuropathic pain conditions. Consideration of complications prior to moving forward with SCS trials and implantation is a vital part of patient management and device selection. Knowledge of these complications can provide physicians and other healthcare professionals the ability to maximize patient outcomes.
RESUMEN
BACKGROUND: Facet joint septic arthritis (FJSA) is an uncommon cause of neck pain, most frequently occurring in the lumbosacral spine. Cervical facet joint septic arthritis is particularly rare. Symptoms typically include spinal or paraspinal pain and tenderness, with severe infections potentially causing neurological impairments. This condition can progress to discitis and osteomyelitis. High clinical suspicion is required for accurate diagnosis and timely treatment. OBJECTIVE: To present the first known case of cervical spine FJSA caused by Moraxella species and provide an updated narrative review of cervical spine FJSA. METHODS: A case study of a 66-year-old male with cervical spine FJSA caused by Moraxella osloensis is detailed. Additionally, a librarian-assisted literature search was conducted on MEDLINE Pubmed, filtering for adult human trials and including various study types, resulting in the inclusion of 9 relevant manuscripts. RESULTS: The patient's symptoms included neck, right upper thoracic, and periscapular pain, with episodes of numbness and tingling. MRI revealed septic arthritis at the C7-T1 facet joint and associated osteomyelitis. Cultures identified Moraxella osloensis as the causative agent. The patient was successfully treated with antibiotics and experienced significant symptom improvement. Literature review highlights that Staphylococcus aureus is the most common causative agent of cervical FJSA, with diagnosis typically involving MRI and culture tests. Treatment generally includes long-term antibiotics, with some cases requiring surgical intervention. CONCLUSIONS: This report underscores the need for high clinical suspicion in diagnosing FJSA and highlights the importance of early intervention. It documents the first known case of cervical spine FJSA caused by Moraxella osloensis, contributing valuable information to the limited literature on this rare condition.
RESUMEN
Chronic knee pain, affecting over 25% of adults in the United States, has surged by 65% over the past two decades leading to rising functional deficits, mobility problems, and a diminished quality of life. While conservative management with pharmacologic and minimally invasive injections are pursued early in the disease process, total knee arthroplasty for refractory osteoarthritis of the knee is often considered. This procedure usually improves pain and functionality within the first three months. However, a significant portion of patients often suffer from postoperative pain that can become chronic and debilitating. We detail the case of a patient with a previous TKA as well as a non-operable patella fracture who obtained significant relief with PNS despite prior conservative and minimally invasive management.

Total neoadjuvant therapy (TNT) is the recommended treatment for locally advanced rectal cancer. The optimal sequence of TNT is debated: induction (chemotherapy first) or consolidation (chemoradiation first)? We aim to evaluate the practice patterns and clinical outcomes of total neoadjuvant therapy with either induction or consolidation regiments in the United States for patients with locally advanced rectal cancer. METHODS: This is a retrospective analysis of the National Cancer Database for patients with clinical stage II or stage III rectal cancer, diagnosed between 2006 and 2017, who underwent total neoadjuvant therapy followed by surgery. RESULTS: From 2006 to 2017, we identified 8999 patients and found that the utilization of induction chemotherapy increased from 2.0% to 35.0%. TNT resulted in pathologic downstaging 46.7% of the time and a pathologic complete response 11.6% of the time. Induction chemotherapy lead to higher pathologic downstaging (58% vs. 44.7%, p < 0.001) and pathologic complete responses (16.8% vs. 10.7%, p < 0.001). Similar trends held true in a multivariate analysis and subset analysis of stage II and III disease. CONCLUSIONS: These findings suggest that induction chemotherapy may be preferred over consolidation chemotherapy when downstaging prior to oncologic resection is desired. The optimal treatment plan for total neoadjuvant therapy is multi-factorial and requires further elucidation.
RESUMEN
Bertolotti's syndrome, also known as lumbosacral transitional vertebrae, is a relatively rare spinal condition characterized by an anatomical variation in the lower spine. Conservative approaches such as physical therapy, anti-inflammatory medications and lifestyle modifications may be recommended for mild cases. In more severe cases or when conservative measures fail to provide relief, injections such as may be considered to alleviate pain. This case is unique in that we document a challenging technique of ipsilateral transforaminal epidural steroid injection in a patient with Bertolotti's syndrome.

Treatment of hematologic malignancies with patient-derived anti-CD19 chimeric antigen receptor (CAR) T-cells has demonstrated long-term remissions for patients with otherwise treatment-refractory advanced leukemia and lymphoma. Conversely, CAR T-cell treatment of solid tumors, including advanced gastric cancer (GC), has proven more challenging due to on-target off-tumor toxicities, poor tumor T-cell infiltration, inefficient CAR T-cell expansion, immunosuppressive tumor microenvironments, and demanding preconditioning regimens. We report the exceptional results of autologous Claudin18.2-targeted CAR T cells (CT041) in a patient with metastatic GC, who had progressed on four lines of combined systemic chemotherapy and immunotherapy. After two CT041 infusions, the patient had target lesion complete response and sustained an 8-month overall partial response with only minimal ascites. Moreover, tumor-informed circulating tumor DNA (ctDNA) reductions coincided with rapid CAR T-cell expansion and radiologic response. No severe toxicities occurred, and the patient's quality of life significantly improved. This experience supports targeting Claudin18.2-positive GC with CAR T-cell therapy and helps to validate ctDNA as a biomarker in CAR T-cell therapy. Clinical Insight: Claudin18.2-targeted CAR T cells can safely provide complete objective and ctDNA response in salvage metastatic GC.

Low back pain (LBP) is a challenging clinical condition for both patients and physicians. It requires a comprehensive initial diagnosis to avoid missing potential causes. One less common cause is superior cluneal neuralgia (SCN), which can present with limited lumbar motion, LBP, buttock pain, or an antalgic gait. While conservative therapies are often first line for LBP, neuromodulation, such as peripheral nerve stimulation (PNS), can be considered for more refractory cases. This case report is unique in that SCN was treated with a temporary PNS system, which provided sustained analgesic benefits without the need for permanent implantation.
RESUMEN
Cervical radicular pain is commonly treated with cervical epidural steroid injections. The transforaminal approach allows for direct treatment of the steroid at a particular nerve root or level. Still, it carries a significant risk of morbidity and mortality with thromboembolism or injury to cervical vasculature. The interlaminar approach is commonly utilized as it avoids vascular structures. However, the epidural space becomes narrower at higher levels, limiting the ability to perform this approach at higher cervical levels. Cervical epidural catheters can be used and advanced to target higher cervical pathology through the interlaminar approach. We present clinical images demonstrating the utility of a cervical catheter for treating higher cervical levels.
RESUMEN
Non-invasive scar management typically involves pressure therapy, hydration with silicones or moisturizers, and UV protection. Moisture loss from scars can lead to hypertrophic scar formation. Pressure therapy reduces blood flow, fibroblast activity, and transforming growth factor beta 1 (TGF-ß1) release. This study examined various moisturizers and liquid silicone gel's impact on microcirculation. 40 volunteers participated in a study where superficial abrasions were created to induce trans epidermal water loss (TEWL). Five moisturizers (TEDRA®, TEDRA® NT1, TEDRA® NT3, Alhydran®, Lipikar®) and BAP Scar Care® silicone gel were tested. TEWL, hydration, and blood flow were measured up to 4 h post-application. Results showed that silicone had the least impact on occlusion and hydration. Alhydran® reduced blood flow the most, while Lipikar® increased it the most. TEDRA® NT1 had reduced flow compared to TEDRA® and TEDRA® NT3. All TEDRA® products exhibited high hydration, and all but silicone showed good occlusion. Moisturizers influenced skin microcirculation, with some causing decrease, while others increased flow. However, the clinical impact on scarring remains unclear compared to the evident effects of hydration and occlusion. More research is necessary to study moisturizers alone and with pressure therapy on scars, along with potential adverse effects of increased microcirculation on scars.
RESUMEN
PURPOSE OF REVIEW: The aim of this review is to educate healthcare professionals regarding buprenorphine for the use of opioid use disorder (OUD) as well as for chronic pain management. This review provides physicians and practitioners with updated information regarding the distinct characteristics and intricacies of prescribing buprenorphine. RECENT FINDINGS: Buprenorphine is approved by the US Food and Drug Administration (FDA) for acute pain, chronic pain, opioid use disorder (OUD), and opioid dependence. When compared to most other opioids, buprenorphine offers superior patient tolerability, an excellent half-life, and minimal respiratory depression. Buprenorphine does have notable side effects as well as pharmacokinetic properties that require special attention, especially if patients require future surgical interventions. Many physicians are not trained to initiate or manage patients on buprenorphine. However, buprenorphine offers a potentially safer alternative for medication management for patients who require chronic opioid therapy for pain or have OUD. This review provides updated information on buprenorphine for both chronic pain and OUD.

Congenitally absent or hypoplastic L5-S1 facet (zygapophyseal) joints are an aberrated rarity, with less than 30 reported cases. This absence of facet joint and contralateral hypertrophic facet provides a continuum of presentations that can complicate low back pain diagnoses and management. A broad differential including lumbar facet syndrome, disc degeneration, spinal stenosis, herniated radiculopathy, spondyloarthropathies and sacroiliac joint pain should be considered initially, with the flexibility for other diagnoses. Understanding the effects of different anatomical, biomechanical and physiological changes on spinal health is essential for patient care. We report a progression of lumbar radiculopathy complicated by the presence of a congenitally absent left L5-S1 facet joint and hypertrophic right L5-S1 facet joint. Furthermore, our discussion concentrates on pathophysiology, differential diagnoses and management of congenitally absent facet joints and the impact they can have on low back pain and spinal health.

Pulmonary hernias are typically a result of trauma, thoracic operations, or congenital defects. Spontaneous lung hernias without a prior overt injury are notably rare. The presence of spontaneous lung hernias has not been reported in post-polio syndrome. Post-polio syndrome is a late sequela of poliomyelitis that usually presents 30-40 years after the initial illness with new presentations of progressive muscle weakness, abnormal muscle fatigue, muscle atrophy, and myalgia. This case report describes the presentation and imaging of a post-polio patient with an atraumatic, spontaneous lung hernia. A discussion on pulmonary hernias, diagnostic imaging, and management is also included.
RESUMEN
The nation's opioid epidemic requires a paradigm shift in the way patients with co-occurring opioid use disorder are treated during episodes of acute pain. Patients are often introduced to prescription opioids after an extremity fracture or sprain or resulting from musculoskeletal back, abdominal, or dental pain. Opioid naive patients who receive their first opioid prescription on discharge from the emergency department may be more likely to develop chronic opioid use compared to patients receiving non-opioid pain medications. This case report will highlight one patient's journey including initial prescription opioid use, escalation into illicit opioids, entry to a recovery and treatment program, discussions with her physician about alternative therapies, and barriers to satisfactory pain relief. A shared decision-making model will be explored.

Aim: Serotonin syndrome (SS) is a life-threatening syndrome that occurs with the use of serotonergic drugs, most commonly due to two or more agents. Cerebral palsy is associated with mood disorders, and more commonly pain, with a prevalence of up to 50-80%. Case presentation: A 58-year-old female with cerebral palsy, metastatic malignancy and mood disorder who presented to the emergency department with acute-on-chronic pain, and signs of SS. She was initiated on iv. dilaudid, titrated off oral medications and scheduled for a left-sided sacroiliac joint injection. Results: It was suspected that due to additional doses of hydrocodone and cyclobenzaprine, she developed moderate-SS. Conclusion: Physicians need to be cognizant of comorbidities and uncommon pain medications that can predispose patients to SS.

The treatment of acute pain over the years has changed with increasing alternative therapies and increased scrutiny of opioid prescriptions. Shared Decision Making (SDM) has become a vital tool in increasing patient engagement and satisfaction in treatment decisions. SDM has been successfully implemented in the management of pain in a variety of settings; however, information regarding the use of SDM for treating acute pain in patients with a history of opioid use disorder (OUD) remains scarce. Following the Preferred Reporting Items for Systematic Reviews and Meta-analysis Extension for Scoping Reviews (PRISMA-ScR), we conducted a review to understand how SDM is used in acute pain management in patients with OUD. We searched Medline, Embase, CINAHL, and PsychInfo databases for relevant articles. Articles were screened and SDM outcomes of eligible articles were charted. The results were grouped by sub-theme based on a 1997 SDM model. There were three original research studies and one quality improvement study. The remaining articles were split evenly between reviews and reviews of clinical guidelines. Four themes emerged from the review: prior judgment and stigma related to OUD, trust and sharing of information, clinical tools, and interprofessional teams. This scoping review consolidated and expounded the current literature on SDM in the management of acute pain in patients with OUD. More work is needed to address prior judgments by both providers and patients and to build greater dialogue. Clinical tools may aid this process as well as the involvement of a multidisciplinary team.
RESUMEN
We present a case report and a literature review of the awake craniotomy procedure for mass resection, with emphasis on the historical aspects, anatomical and surgical considerations, and, uniquely, a patient's experience undergoing this procedure. This procedure is a safe and effective method for lesion resection when working in and around eloquent brain. We have described our process of guiding a patient through an awake craniotomy procedure and detailed the patient's experience in this study. We also conducted a systematic literature review of studies involving awake craniotomy over three years, 2018-2021. Lastly, we compared the methodology used by our institution and the current mostly used methods within the neurosurgical community. Several studies were identified using PubMed and Google Scholar. Awake craniotomy is a safe and effective method of achieving a high rate of resection of lesions located in and around the eloquent cortex with a low degree of postoperative neurological deficit.
