Neurologic Approach to Radiculopathy, Back Pain, and Neck Pain.

Back pain and neck pain are common in clinical practice, but significant challenges and pitfalls exist in their diagnosis, treatment, and management. From the neurologic standpoint, cervical radiculopathy and lumbosacral radiculopathy are characterized by neck pain or back pain accompanied by sensory and motor symptoms in an arm or leg. The basic neurologic examination is vital, but testing like electromyography and MRI is often needed especially in cases that fail conservative management. Oral medications, injection-based therapies, physical therapy, and surgical evaluation all have a place in the comprehensive neurologic management of back and neck pain and associated radiculopathy.

Real-world study of intranasal ketamine for use in patients with refractory chronic migraine: a retrospective analysis.

INTRODUCTION: Subanesthetic ketamine infusion has been used for managing refractory headache in inpatient or outpatient infusion settings. Intranasal ketamine may be an alternative option for outpatient care. METHODS: A retrospective study was conducted at a single tertiary headache center to assess the clinical effectiveness and tolerability of intranasal ketamine in patients with refractory chronic migraine. Candidates who received intranasal ketamine between January 2019 and February 2020 were screened through an electronic medical record query. Manual chart reviews and structured telephone interviews were conducted on obtaining informed consent. RESULTS: Of 242 subjects screened, 169 (79.9% women) of median (IQR) age 44 (22) years were interviewed. They reported a median (IQR) of 30 (9) monthly headache days and tried 4 (1) classes of preventive medications. Overall, they used 6 (6) sprays per day, with a median (IQR) of spray use of 10 (11) days per month. Intranasal ketamine was reported as 'very effective' in 49.1% and the quality of life was considered 'much better' in 35.5%. At the time of the interview, 65.1% remained current intranasal ketamine users and 74.0% reported at least one adverse event. CONCLUSION: In this descriptive study, intranasal ketamine served as an acute treatment for refractory chronic migraine by reducing headache intensity and improving quality of life with relatively tolerable adverse events. Most patients found intranasal ketamine effective and continued to use it despite these adverse events. Given the potential for overuse, it should be reserved for those clearly in need of more effective rescue treatment with appropriate safety precautions. Well-designed prospective placebo-controlled trials are necessary to demonstrate the efficacy and safety of intranasal ketamine in patients with migraine.

Supporting Women's BIA-ALCL Decision-making: Role of the Individual Consult in Empowering the Patient-Physician Team.

BACKGROUND: Breast implant associated anaplastic large cell lymphoma (BIA-ALCL) is a T-cell non-Hodgkin's lymphoma and an uncommon risk of textured breast implants. Over the past decade, concern about BIA-ALCL has been increasing among both patients and surgeons. Patients are seeking a better understanding of their BIA-ALCL risk toward identifying a personalized care plan. This quality improvement project examines the value added by pairing group-based patient education seminars with one-on-one consults. METHODS: Individual consults were held following educational group seminars. Consult field notes underwent qualitative thematic analysis. Themes were cross referenced against a quantitative chart review of patient BIA-ALCL prophylaxis decisions over time. RESULTS: Four key themes were identified: weighing, perceiving, guiding, and supporting. Weighing considers the risk-benefit assessments patients make when weighing their BIA-ALCL risk. Perceiving describes the underlying psychosocial factors that frame patient perceptions of BIA-ALCL risk. Guiding presents the levels of guidance that patients require when making BIA-ALCL prophylaxis decisions. Supporting explores the therapeutic value of the individual consult. Ultimately, 41% of post-seminar consult attendees sought explantation, compared with 4% among patients who did not participate in this program (P < 0.001). CONCLUSIONS: Key lessons include the following: (1) patients weigh BIA-ALCL risk against perceived surgical risks and the value of their reconstruction; (2) patients can benefit from a personalized balance of autonomy and surgeon guidance when selecting a BIA-ALCL prevention plan; (3) surgeons should seek to understand the psychosocial factors that may underlie patient perceptions of BIA-ALCL risk; and (4) individual consults can be therapeutic and help strengthen the patient-surgeon relationship.

Navigating Women's BIA-ALCL Information Needs: Group Seminars May Offer an Opportunity to Empower the Patient-Surgeon Team.

BACKGROUND: Breast Implant Associated Anaplastic Large Cell Lymphoma (BIA-ALCL) is a T-cell non-Hodgkin's lymphoma that has been linked to textured breast implants, and is an emerging concern within the plastic and reconstructive surgery community. Many surgeons are struggling with how best to inform their patients and manage BIA-ALCL care without overwhelming their standard clinical practice. METHODS: Five educational group seminars were held for 53 patients. A thematic analysis of the field notes taken at each seminar was conducted to identify recurring patient and surgeon behaviors. RESULTS: The thematic analysis identified 5 key themes: seeking, amplifying, framing, trusting, and empowering. Seeking describes the knowledge sought by patients and their varying engagement in their care. Amplifying underlines how the emotionally charged topic of BIA-ALCL impacted patient and surgeon behaviors. Framing presents surgeon efforts to help patients understand the risk level of BIA-ALCL. Trusting addresses the ways BIA-ALCL has impacted patient trust in the medical community and the mechanisms to rebuild this trust. Empowering outlines surgeon efforts to engage patients in shared decision-making. CONCLUSIONS: Herein is presented a possible framework for efficient BIA-ALCL patient education that can be adapted to different surgical practices. Lessons learned are: (1) patients want information on BIA-ALCL's clinical features and prophylactic implant removal; (2) BIA-ALCL discussions are emotionally charged and surgeons must remain cognizant of group dynamics and that the physician-patient power differential may impact patient decision-making; (3) patient trust has been strained but can be restored; and (4) patient responses to BIA-ALCL are variable and subjective; thus, surgeons should emphasize patient-centered care.

Transgenic mouse model with deficient mitochondrial polymerase exhibits reduced state IV respiration and enhanced cardiac fibrosis.

Mitochondria produce the energy required for proper cardiac contractile function, and cardiomyocytes that exhibit reduced mitochondrial electron transport will have reduced energy production and decreased contractility. Mitochondrial DNA (mtDNA) encodes the core subunits for the protein complexes of the electron transport chain (ETC). Reduced mtDNA abundance has been linked to reduced ETC and the development of heart failure in genetically engineered mice and in human diseases. Nucleoside reverse-transcriptase inhibitors for HIV/AIDS are used in antiretroviral regimens, which cause decreased mtDNA abundance by inhibiting the mitochondrial polymerase, pol-γ, as a limiting side effect. We explored consequences of AZT (1-[(2R,4S,5S)-4-azido-5-(hydroxymethyl)oxolan-2-yl]-5-methylpyrimidine-2,4-dione) exposure on mtDNA abundance in an established transgenic mouse model (TG) in which a cardiac-targeted mutant form of pol-γ displays a dilated cardiomyopathy (DCM) phenotype with increased left ventricle (LV)-mass and increased LV-end diastolic dimension. TG and wild-type littermate mice received 0.22 mg per day AZT or vehicle for 35 days, and were subsequently analyzed for physiological, histological, and molecular changes. After 35 days, Y955C TGs exhibited cardiac fibrosis independent of AZT. Reduced mtDNA abundance was observed in the Y955C mouse; AZT treatment had no effect on the depletion, suggesting that Y955C was sufficient to reduce mtDNA abundance maximally. Isolated mitochondria from AZT-treated Y955C hearts displayed reduced mitochondrial energetic function by oximetric measurement. AZT treatment of the Y955C mutation further reduced basal mitochondrial respiration and state IV(0) respiration. Together, these results demonstrate that defective pol-γ function promotes cardiomyopathy, cardiac fibrosis, mtDNA depletion, and reduced mitochondrial energy production.
