Throughout the world, chili and chili powders are spices of considerable economic importance. Rocoto (Capsicum pubescens R. & P.) is a chili pepper used in Andean cuisine. Fresh chili is perishable and therefore it is convenient to protect the capsaicin, color and other bioactive compounds through preservation methods such as encapsulation. The present study systematically evaluates the technical and environmental aspects of producing encapsulated Rocoto red chili powder using three different wall materials—maltodextrin, rice protein and rice flour—in conjunction with two drying methods, namely convection drying and vacuum drying. Our technical objectives focused on developing an encapsulated product with high heat and vibrant red color, key attributes that significantly influence consumer purchasing behavior. In addition, the study aimed to mitigate the loss of polyphenols, flavonoids and antioxidant activity. After identifying the optimal conditions for each wall material and drying process, a comprehensive environmental assessment was conducted to identify the most efficient and sustainable production methods. The results demonstrate that rice flour encapsulation (20%) in conjunction with hot air drying (40 °C) represents the most efficacious method for the preservation of chili powder’s pungency. This approach resulted in a mere 24% reduction in Scoville units while maintaining the powder’s vibrant red coloration. This method not only preserved key bioactive compounds, including capsaicin, polyphenols and flavonoids, but also significantly enhanced the antioxidant capacity of the product. From an environmental perspective, this approach offers significant sustainability benefits, reducing the overall environmental impact by approximately 72% compared to vacuum drying of unencapsulated chili. The use of rice flour as an encapsulant aligns with sustainability goals, making it the most efficient option for balancing product quality and environmental performance.
Monachophobia in Russia: Peter the Great and His Influence
Authors: Zapalskii Gleb
Published: October 2024

The reforms of Russian Tsar Peter I (1682–1725) touched all spheres of life, including the Church. The purpose of this paper is to bring into focus his approach to the reform of monasticism. It reflects on Peter’s personal remarks as reported both by his Russian and his foreign interlocutors, his legislation, including law drafts, and practical measures such as the All-Joking, All-Drunken Synod. The principal conclusion is that it was this Russian ruler who was the first to call into question the very existence of monasticism and who came close to the ultimate dissolution of monasteries. He did not abolish monasticism not because it was a too radical step but because he devised measures of reform to raise its standards and improve its public utility. His treatment of the monastic tradition should be interpretated not as secularization but rather as modernization. Peter’s personal “monachophobia” is best understood as a modernizing impulse. His objective was the creation of a “modern” state whose Church and clergy represented contemporary values. Traditional, unreformed monasticism presented an obstacle in his progress towards this goal. The legacy of Peter’s policy was an increasing monachophobia in Russia apparent from the 18th century onwards.

Published: October 2024

This paper presents a structural–parametric synthesis of the four-link and Stephenson I, Stephenson II, and Stephenson III six-link path-generating mechanisms. The four-link path-generating mechanism is formed by connecting the output point and the base using an active closing kinematic chain (CKC) with two DOFs and a negative CKC of the type RR. The six-link path-generating mechanisms are formed by connecting the output point and the base by active, passive and negative CKCs. Active CKC has active kinematic pair, passive CKC has zero DOF, and negative CKC has a negative DOF. Active and negative CKCs impose geometrical constraints on the movement of the output point, and the geometric parameters of their links are determined by least-square approximation. Geometric parameters of the passive CKC are varied to satisfy the geometrical constraints of the active and negative CKCs. The CKCs of the active, passive and negative types, connecting the output point and the base, are the structural modules from which the different types of the path-generating mechanisms are synthesized. Numerical examples of the parametric synthesis of the four-link and six-link path-generating mechanisms are presented.
A Numerical Integrator for Kinetostatic Folding of Protein Molecules Modeled as Robots with Hyper Degrees of Freedom
Authors: Kacem Amal , Zbiss Khalil , Mohammadi Alireza
Published: October 2024

The kinetostatic compliance method (KCM) models protein molecules as nanomechanisms consisting of numerous rigid peptide plane linkages. These linkages articulate with respect to each other through changes in the molecule dihedral angles, resulting in a kinematic mechanism with hyper degrees of freedom. Within the KCM framework, nonlinear interatomic forces drive protein folding by guiding the molecule’s dihedral angle vector towards its lowest energy state in a kinetostatic manner. This paper proposes a numerical integrator that is well suited to KCM-based protein folding and overcomes the limitations of traditional explicit Euler methods with fixed step size. Our proposed integration scheme is based on pseudo-transient continuation with an adaptive step size updating rule that can efficiently compute protein folding pathways, namely, the transient three-dimensional configurations of protein molecules during folding. Numerical simulations utilizing the KCM approach on protein backbones confirm the effectiveness of the proposed integrator.
Optimistic Third-Party Sellers in E-Commerce Supply Chains
Authors: Li Jialu , Tayi Giri K.
Published: October 2024

This paper investigates the effects of optimism in an e-commerce supply chain where two third-party sellers offer substitutable products through a shared e-commerce platform. In this context, optimism is defined as a cognitive bias in which third-party sellers underestimate the probability of encountering low market potential. We present a game-theoretic model to characterize the equilibrium strategies of both the platform and the sellers. Our analysis reveals that when both sellers exhibit optimism bias, this bias invariably leads to lower expected profits for them. However, seller optimism can benefit both the platform and the whole system. That is, as sellers become more biased, the profits of the platform and the entire supply chain increase. Moreover, when a biased seller competes with a sophisticated one, unilateral optimism can result in a win–lose outcome in which the optimistic seller benefits from her bias at the expense of her sophisticated rival. Indeed, we demonstrate that optimism can confer a competitive advantage in a duopoly, allowing the more biased seller to earn higher profits than its less biased competitor—even if the latter is unbiased or sophisticated. Our work sheds light on the conditions under which optimism bias may have detrimental or beneficial impacts on e-commerce supply chain operations.

Published: October 2024

Developing efficient and sustainable pollution control technologies has become a research priority in the context of escalating global environmental pollution. Nano zero-valent iron (nZVI), with its high specific surface area and strong reducing power, demonstrates remarkable performance in pollutant removal. Still, its application is limited by issues such as oxidation, passivation, and particle aggregation. White rot fungi (WRF) possess a unique enzyme system that enables them to degrade a wide range of pollutants effectively, yet they face challenges such as long degradation cycles and low degradation efficiency. Despite the significant role of nZVI in pollutant remediation, most contaminated sites still rely on microbial remediation as a concurrent or ultimate treatment method to achieve remediation goals. The synergistic combination of nZVI and WRF can leverage their respective advantages, thereby enhancing pollution control efficiency. This paper reviews the mechanisms, advantages, and disadvantages of nZVI and WRF in pollution control, lists application examples, and discusses their synergistic application in pollution control, highlighting their potential in pollutant remediation and providing new insights for combined pollutant treatment. However, research on the combined use of nZVI and WRF for pollutant remediation is still relatively scarce, necessitating a deeper understanding of their synergistic potential and further exploration of their cooperative interactions.

Published: October 2024

Recently, there has been fast-growing interest among researchers in discovering bioactive peptides from insects and evaluating their potential applications in livestock production. The present study aimed to assess the antioxidant properties and stability of fly maggot peptide (FMP) and its effects on Arbor Acres (AA) broilers’ oxidative stress induced by lipopolysaccharide (LPS) and hemocoagulase (HC). A total of 108 one-day-old AA broilers were randomly divided into six groups: CG (normal saline, basal diet), DG (LPS + HC, basal diet), VG (DG + vitamin C 50 ug/kg), LPG (DG + FMP 5 mg/kg), MPG (DG + FMP 15 mg/kg), and HPG (DG + FMP 25 mg/kg). The results showed that the addition of FMP to the diet promoted LPS+ HC-induced increases in average daily gain (ADG), total superoxide dismutase (T-SOD), total antioxidant capacity (T-AOC). Meanwhile, FMP regulated the intestinal morphology. Additionally, FMP decreased the increase in the contents of malondialdehyde (MDA), the relative weight of immune organs, interleukin-1β (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α). In conclusion, this research suggested that the addition of FMP can relieve the LPS+ HC-induced oxidative stress of AA broilers and the recommended dose of FMP is 25 mg/kg. This study presents a theoretical foundation for the addition of an FMP supplement for the purpose of protecting broilers’ growth.
Optimizing the Activation of WWTP Wet-Weather Operation Using Radar-Based Flow and Volume Forecasting with the Relative Economic Value (REV) Approach
Authors: Courdent Vianney , Munk-Nielsen Thomas , Mikkelsen Peter Steen
Published: October 2024

Wastewater treatment plants (WWTPs) connected to combined sewer systems must cope with high flows during wet-weather conditions, often leading to bypass and thus pollution of water bodies. Radar rainfall forecasts coupled with a rainfall-runoff model provides flow and volume forecasts that can be used for deciding when to switch from normal to wet-weather operation, which temporarily allows for higher inflow. However, forecasts are by definition uncertain and may lead to potential mismanagement, e.g., false alarms and misses. Our study focused on two years of operational data from the Damhuså sewer catchment and WWTP. We used the Relative Economic Value (REV) framework to optimize the control parameters of a baseline control strategy (thresholds on flow measurements and radar flow prognosis) and to test new control strategies based on volume instead of flow thresholds. We investigated two situations with different objective functions, considering higher negative impact from misses than false alarms and vice versa, and obtained in both cases a reduction of the rate of false alarms, higher flow thresholds and lower bypass compared to the baseline control. We also assess a new control strategy that employs thresholds of predicted accumulated volume instead of predicted flow and achieved even better results.

Currently, water pollution caused by dyes is a serious problem since they are toxic and carcinogenic to living beings. To reduce the presence of these contaminants, natural adsorbents have been considered as they are easy to obtain, inexpensive, and have high removal efficiency. In this work, the adsorption process using natural brushite (nDCPD) was studied for the removal of phenol red (PR), achieving a removal rate of 99.15% and an adsorption capacity of 82.24 mg/g, and gentian violet (GV), achieving a removal rate of 97.03% and an adsorption capacity of 74.22 mg/g. Equilibrium adsorption occurs for both dyes in multiple layers on the surface. The adsorption process is spontaneous for both dyes. The kinetics of the adsorption process involve using a single active site on the surface for PR adsorption, while for GV, two active sites on the surface are required. Analysis via FTIR, EDS, and XRD revealed various mechanisms that intervene in the adsorption process of both dyes on the surface of nDCPD, such as electrostatic forces, functional groups, physisorption, and ion exchange.

Key Points

Health-related quality of life in dialysis depends on many nonclinical factors.

Psychosocial determinants contribute to explaining variance in health-related quality-of-life domains better than demographic and medical variables alone.

In comparison with past small-scale studies, self-efficacy showed significant associations with all aspects of health-related quality of life.

Background

We investigated whether psychosocial determinants self-efficacy and social support are associated with health-related quality of life in patients on hemodialysis enrolled in the CONVINCE trial.

Methods

We used baseline data from the cohort of patients involved in the CONVINCE randomized trial of hemodiafiltration versus hemodialysis. Measures included age, sex, relationship status, children, housing, education, employment, comorbidities, dialysis schedules, time of first dialysis, residual kidney function, general self-efficacy and social support scores, and Patient-Reported Outcomes Measurement Information System measurements for health-related quality of life. Associations were analyzed using hierarchical regression.

Results

One thousand three hundred sixty patients from the CONVINCE trial were the cohort of interest. The mean age was 62±13.5 years (range, 20–92), and 66.9% were male. Self-efficacy was a significant predictor for all health-related quality-of-life domains: depression (β=−0.36, P < 0.001), anxiety (β=−0.35, P < 0.001), social participation (β=0.32, P < 0.001), cognition (β=0.29, P < 0.001), fatigue (β=−0.29, P < 0.001), physical function (β=0.27, P < 0.001), sleep disturbance (β=−0.23, P < 0.001), pain interference (β=0.21, P < 0.001), pain intensity (β=−0.17, P < 0.001), interdialytic symptoms (β=−0.14, P = 0.002), and intradialytic symptoms (β=−0.14, P = 0.002). Social support was a significant predictor for cognition (β=0.21, P < 0.001), sleep disturbance (β=−0.11, P = 0.017), and intradialytic symptoms (β=−0.11, P = 0.02).

Conclusions

Higher general self-efficacy scale scores are associated with improvements in cognition, depression, anxiety, social participation, fatigue, physical function, sleep disturbance, pain interference, interdialytic symptoms, pain intensity, and intradialytic symptoms. Associations for self-efficacy are larger than those for social support and stronger than previously reported. It is plausible that targeted psychosocial interventions may improve health outcomes in people on hemodialysis.

Sodium-ion batteries (SIBs) have been commercialized in 2023 and are expected to capture a substantial market share in the future. However, the material systems in SIBs are very similar to those in lithium-ion batteries (LIBs), which necessitate consideration of recycling in terms of safety issues, environmental concerns, and economic values. In this study, we present the first evaluations of the disassembly of spent commercialized SIBs and the leaching and regeneration of their cathode material (NaNi

The primary challenge in recycling is that failed cathode materials are difficult to dissolve in traditional inorganic acids, with an extraction rate of only 57.4% even when a reducing agent is added. Fortunately, there is a possibility for the failed NaNi

Published: October 2024

Background: There are many growth and development problems that occur in children, including stunting. Stunting is a condition of growth failure in children under five due to chronic malnutrition so that children are too short for their age. Malnutrition occurs from the time the baby is in the womb and in the early period after the baby is born, however, stunting conditions are only visible after the baby is 2 years old. Thus the period of 1000 HPK should receive special attention because it determines the growth rate of physique, intelligence, and productivity in the future. In 2020, the national stunting prevalence rate was 27.6%. In Bukittinggi city, the stunting rate in 2021 is 19%. This figure is still far from the national target for 2024 to 14%. Given the importance of stunting prevention, researchers are interested in conducting research on the Influence of 1000 HPK Video Media on Increasing Knowledge and Attitudes of Uisa Subur Couples as Stunting Prevention Efforts at the Guguk Panjang Health Center.Purpose: To determine the influence of health promotion media videos about 1000 HPK on increasing knowledge and changing attitudes of mothers of couples of childbearing age as an effort to reduce the incidence of stuntingMethods: This study is a quasi-experimental study, which uses a one-group pre-test post test design, with a sample of 18 people in the Guguk Panjang Health Center work area.Results: The results showed that before being given education through video media about 1000 HPK, the average maternal knowledge was 7.44 and after it was carried out it became 9.61. The average attitude of mothers before being given education was 34.88 and after it was carried out it was 37.88.Conclusion: There is an influence of 1000 HPK video media education as an effort to prevent stunting on increasing the knowledge and attitudes of mothers of couples of childbearing age at the Guguk Panjang health center..

The prevailing features of the environment of modern countries are uncertainty, chaos and a completely new quality of emerging changes. The contemporary international environment is complex and multidimensional, and the conflict in Ukraine that has been ongoing since 2014 is a factor that significantly destabilizes it. When analyzing the situation in the region in the context of regional security complexes, issues related to Poland’s security should also be viewed through the prism of the situation in Ukraine, which is its direct neighbor. Russia’s attack on Ukraine destabilized the security environment in Europe and strengthened the concerns of those in power to ensure Poland’s security and mobilized the international community to take active action. The aim of this article is therefore to try to find an answer to the question: what is the state of Poland’s security environment? What implications does the war in Ukraine have for Poland’s security?In order to effectively solve the research problem, an attempt will be made to answer the following research questions: What is Poland’s security environment in terms of the changes that have occurred in the international arena as a result of Russia’s aggression against Ukraine? What consequences does the war in Ukraine have for the security of Poland? Is it possible to predict, albeit to a limited extent, scenarios for Poland’s security environment in the Ukrainian context? This article is an attempt to look at Poland’s security environment in the aspect of changes that have occurred in the international arena as a result of the Russian invasion of Ukraine.

Dorsal Column Spinal Cord Stimulation for Sacral Radiculopathy Due to Sacroiliac Joint Fusion to Hardware: A Case Report
Authors: Fisher Kristy
Published: October 2024

BACKGROUND: A complication of sacroiliac joint (SIJ) fusion is neuropathic pain due to intruding hardware. CASE REPORT: We present the novel management of a 57-year-old man who presented with S1 radiculopathy that began immediately after SIJ fusion, which had been performed 2 years prior. Physical exam and electromyography confirmed right S1 radiculopathy. Imaging confirmed hardware protrusion into the S1 neural foramen. The patient failed conservative management, and an outside tonic spinal cord stimulator trial (SCS) trial, but experienced 100% relief during the anesthetic phase of S1 transforaminal epidural steroid injections. A neurosurgical consult deemed the patient to be an inappropriate candidate for surgical revision due to the complete fusion of the hardware to bone. The patient successfully underwent a burst SCS trial with 100% relief as measured by the Numeric Rating Scale and increased his quality of sleep and activity with subsequent permanent implantation. CONCLUSION: SCS utilizing burst stimulation can offer a unique treatment option for resultant neuropathic pain from SIJ fusion to hardware in the event that surgical revision is not recommended. KEY WORDS: Spinal cord stimulator, scral radiculopathy, sacroiliac joint, failed back surgery syndrome, case report
Systemic Allergic Reaction to a Spinal Cord Stimulator Trial: A Case Report
Authors: Heard Sara
Published: October 2024

BACKGROUND: Spinal cord stimulation (SCS) is commonly used for the management of chronic pain conditions, such as intractable axial and radicular back pain, complex regional pain syndrome, and painful peripheral vascular disease. Patients have had adverse complications with SCS trials and permanent implants. Cases of contact dermatitis from SCS devices have been reported, but a systemic allergic reaction to an SCS trial has not yet been published to date. CASE REPORT: A 52-year-old woman with complex regional pain syndrome type II and a history of a presumed infectious reaction to a previous SCS trial 8 years prior presented with chronic right L5, S1 radicular pain. Having failed conservative measures, she underwent a repeat SCS trial. The lead was placed at the T8 vertebral body, migrated several days later to the T9 vertebral body, and was subsequently adjusted back to T8 under fluoroscopic guidance. The patient reported improvement in her back and leg pain. Three days later, she presented to the emergency department with subjective fever, headache, rigors, chills, diaphoresis, nausea, vomiting, and diarrhea. The lead was removed, and the patient’s acute symptoms resolved within 48 hours. CONCLUSIONS: Systemic allergic reactions to SCS can be significant and lead to device removal despite improvement in pain symptoms. Further case reports and studies are needed to elucidate the risks associated with SCS placement, such as allergic reaction, infection, and neurologic injury.

Superior Cluneal Nerve Schwannoma as a Cause of Intractable Ipsilateral Low Back Pain: A Case Report
Authors: Simha Siddartha
Published: October 2024

BACKGROUND: Superior cluneal nerve (SCN) entrapment is an infrequent, yet commonly missed etiology of low back pain (LBP). The SCN is prone to entrapment as it travels through the iliocostalis muscle and exits thoracolumbar fascia via an osseofibrous tunnel as it courses over the iliac crest. CASE REPORT: A patient with chronic LBP exhibited new provocative sacroiliac joint testing not responsive to injections. Subsequent pelvis magnetic resonance imaging revealed a peripheral nerve sheath tumor of the right SCN. Although she exhibited an excellent response to therapeutic nerve blocks, her silicone allergy excluded her from peripheral nerve stimulation as a treatment option. She underwent SCN neurolysis and tumor resection by the neurosurgery department resulting in symptom resolution. CONCLUSION: Interventional pain physicians should consider SCN entrapment when diagnosing intractable LBP. In the event of rare etiologies of SCN entrapment, such as neurogenic tumors, a multidisciplinary patient-centered care approach should be sought for symptom management. KEY WORDS: Superior cluneal nerve, pain management, chronic pain, nerve block, schwannoma
Percutaneous Femoral Nerve Stimulation for Overactive Bladder: A Case Report
Authors: Helm Standiford
Published: October 2024

BACKGROUND: Peripheral nerve stimulation has been used to treat overactive bladder. A possible mechanism of action may be retrograde neuromodulation of the parasympathetic system via the sacral plexus. If the retrograde neuromodulation theory is correct, then stimulation of any nerve not arising from the sacral plexus should not improve overactive bladder symptoms. CASE REPORT: We present a case of femoral nerve stimulation for neuropathic pain. While the stimulation did not relieve the neuropathic pain, it did successfully treat our patient’s hyperactive bladder. CONCLUSIONS: The femoral nerve arises in part from L2, the lowest level of the sympathetic system. The sympathetic system is involved with relaxation of the bladder. This report shows that nerves not arising from the sacral plexus can relieve overactive bladder symptomology. A refinement of the retrograde neuromodulation theory may be called for, with the inclusion of sympathetic neuromodulation as an alternative means to treat hyperactive bladder. KEY WORDS: Overactive bladder, tibial nerve stimulation, femoral nerve stimulation, peripheral nerve stimulation, mechanism of action, case report
Sphenopalatine Ganglion Block for Postacute Sequelae SARS-CoV-2 Infection Headaches: A Case Report and Review of the Literature
Authors: Bruel Brian
Published: October 2024

BACKGROUND: In a subset of patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), neurological symptoms including “brain fog” and headache persist beyond the acute phase of the infection, often referred to as postacute sequelae SARS-CoV-2 infection (PASC), or Long COVID. Current practice supports a multi-modal approach to address PASC symptoms. One technique for chronic headaches not utilized for PASC is sphenopalatine ganglion blocks (SPGB). We evaluate the pathophysiology of PASC headaches, review the utilization of sphenopalatine ganglion blocks in primary headaches, and discuss the potential for SPGB in PASC headaches. CASE REPORT: We present a patient with PASC headaches who failed various conservative and interventional therapies. Worsening symptoms resulted in pursuing bilateral SPGB, resulting in an 80% improvement in symptoms. To our knowledge, we report the first PASC headache treated with an SPGB via infrazygomatic injection. CONCLUSION: SPGB can treat PASC headaches and improve a patient’s quality of life. KEY WORDS: Sphenopalatine ganglion block, Long COVID, PASC, headaches, case report
Peripheral Nerve Stimulation with a High Frequency Electromagnetic Coupled (HF-EMC) Powered Implanted Neurostimulator with Receiver at the Suprascapular and Supraclavicular Nerves for the Treatment of Chronic Shoulder Pain: Case Report
Authors: Patel Silky
Published: October 2024

Background: Over 20% of adults are affected by chronic shoulder pain that can limit the use of the upper extremity and decrease the overall quality of life. Peripheral nerve stimulation (PNS) is an emerging treatment for refractory cases of chronic pain that has been receiving heightened attention in recent years with growing documentation of favorable results. This report discusses a case of chronic shoulder pain effectively managed with PNS. Case Report: A 58-year-old man, with a history of cervical laminectomy presented with persistent pain of the left shoulder, radiating down the medial aspect of the left upper arm to the elbow, and pain along the upper trapezius between the neck and shoulder that did not ease after successful shoulder joint replacement. The pain averaged 8/10 and escalated to 10/10 with arm movement or lifting over 5 pounds. Once agitated, the pain would stay elevated for several hours. The patient eventually withdrew completely from social activities and stopped leaving his home except when absolutely necessary to avoid additional pain brought on by activity. Previous treatments, including physical therapy, opioids, nonsteroidal anti-inflammatory drugs (NSAIDS), and cervical epidural steroid injection, were unsuccessful in managing pain. The patient did, however, achieve relief with peripheral nerve stimulation. Pain scores at 3-month follow-up decreased from 8/10 without and 10/10 with activity to an average of 1/10 with increased activity, complete cessation of pain medication, and reported improvement in quality of life. These results have been maintained at 12 months post-implant. Conclusion: Sub-threshold peripheral nerve stimulation with an externally powered system at the suprascapular and supraclavicular nerves was an effective treatment for a patient suffering from debilitating pain in the shoulder, upper arm, and upper trapezius after a successful, structurally sound shoulder replacement did not reduce persistent chronic pain.

Novel and Effective Use of Peripheral Nerve Stimulation to Treat Trauma-induced Chronic Shoulder Pain: A Case Report
Authors: Mendelson Andrew
Published: October 2024

Background: Peripheral nerve stimulators (PNS) are an option when medications, injections, physical therapy, and transcutaneous electrical stimulation are not effective. Rotator cuff muscle disorders and acromioclavicular or glenohumeral joint pathologies commonly lead to chronic shoulder pain. However, this case report documents a PNS treating chronic shoulder pain following traumatic humeral fracture. Case Report: Our patient presented years after her orthopedic team recommended nonoperative management for her traumatic humeral fracture. She described pain at rest (3-5/10), which was exacerbated by forward flexion and abduction (9/10). After her PNS, she noted greater than 80% pain relief (rating it a 3/10), as well as improved range of motion and improved pain with movement, 4/10 with movement. Conclusion: This case is the first report of PNS use for traumatic humeral fracture, when the patient’s clinical status precluded operative intervention. Our patient reported satisfaction with her pain relief and improved range of motion.

Postdural Puncture Headache, Subdural Hematoma, and Sixth Cranial Nerve Palsy Lumbar Following Spinal Drain, Resolved with Epidural Blood Patch: Case Report
Authors: Walton Edward
Published: October 2024

BACKGROUND: Postdural puncture headache (PDPH) is a known potential complication of lumbar drain placement. Data regarding incidence of PDPH after lumbar drain placement varies, with a range of 0% to 47%. Furthermore, spinal drain placement has been associated with a significantly increased risk of debilitating neurologic complications. CASE REPORT: In this article, we describe the case of a patient who developed PDPH, subdural hematoma, and abducens nerve palsy after lumbar drain. The patient was treated successfully with epidural blood patch. To our knowledge, this is the first case report of a patient who developed all 3 of these complications following spinal drain placement. CONCLUSION: Dural puncture, whether accidental or purposeful, carries a risk of multiple serious neurological sequelae. After spinal drain placement, close monitoring for symptoms of intracranial hypotension should ensue with a plan for treatment in the event the patient develops a PDPH or other neurologic sequelae. KEY WORDS: Epidural blood patch, headache, postdural puncture headache
Treatment of a Patient with Severe Rash Pain Secondary to Monkeypox Virus: A Case Report
Authors: Nguyen Trong
Published: October 2024

BACKGROUND: The following case describes a multimodal analgesic approach for pain control in a patient with monkeypox (mpox) lesions. CASE REPORT: A 48-year-old man presented with a positive mpox test, an inability to tolerate solid foods due to severe throat pain and painful oral lesions, and severe genital burning and rectal pain. The pain management team utilized a multimodal analgesia regimen, which included a viscous lidocaine mouth solution, lidocaine jelly for perineal pain, acetaminophen, ketorolac, gabapentin, and oxycodone. On the following day, he was able to tolerate solid food and reported significantly less pain with defecation and urination. CONCLUSION: This case report introduces an effective multimodal approach for pain control of mpox related lesions, which utilizes viscous and/or jelly lidocaine, acetaminophen, gabapentin, nonsteroidal antiinflammatory drugs, such as ketorolac, and opioids, such as oxycodone.

Cooled Radiofrequency Ablation for Lumbar Facet Pain in Context of Lumbar Instrumentation and Cardiac Pacemaker: A Case Report
Authors: Wang Eric
Published: October 2024

BACKGROUND: Many patients with severe axial lumbar pain due to the facet joints (i.e., facet arthropathy) have pain refractory to lumbar surgical instrumentation. Patients who have facet-mediated pain refractory to surgical management may benefit from radiofrequency ablation (RFA) of any remaining medial branch nerves, but RFAs in proximity to spinal instrumentation can cause thermal damage. In addition, many of these patients are older and potentially have cardiac implantable electrical devices (CIEDs). RFAs generate electromagnetic interference, which may damage or interrupt the function of CIEDs. Pain physicians may have safety concerns regarding performing RFAs for patients with lumbar instrumentation and CIEDs. CASE REPORT: We describe a case in which we safely performed 2 lumbar cooled RFAs in a staged fashion in a patient who had previous lumbar instrumentation, as well as a cardiac pacemaker. The patient reported near-complete bilateral pain relief without periprocedural pain, and no changes on electrocardiography or complications were observed. CONCLUSION: RFAs may be safely performed in patients with CIEDs and pre-existing instrumentation if society-based practice guidelines are followed.
