Implementing a paradigm shift: incorporating pain management competencies into pre-licensure curricula.

OBJECTIVE: The purpose of this article is 1) to present the historical context and rationale for competency-based pain management education; and 2) to suggest learning tools that faculty might apply into their teachings and their institutions' pre-licensure curricula for promoting conceptual learning based on competency-based pain management education. DESIGN: Based on the well-documented need to improve the competency of health care professionals in pain assessment and management, an interprofessional group of health care providers collaborated and then convened in August 2012 to develop core competencies for pain management for the pre-licensure programs of study across health care disciplines. This interprofessional group of pain educators achieved consensus on a common set of pain-related competencies intended to be implemented across a variety of pre-licensure professional programs. SETTING: A group of the interprofessional faculty, who participated in the development of the core competencies for pain management, provides a follow-up of how to implement learning tools within teaching and curricula, based on competency education in pre-licensure health care. RESULTS: Broad questions about how to incorporate competencies into pre-licensure curricula, for all health provider pre-licensure programs, including how to assess competency across individuals and how to teach in ways that emphasize the demonstration of conceptual learning, remain unanswered. This article reviews how the use of competencies creates historical context for a shift from teaching to learning and concludes with suggestions and exemplars in applying core competencies for pain management in pre-licensure programs.

Effects of Leg Length, Sex, Laterality, and the Intermediate Femoral Cutaneous Nerve on Infrapatellar Innervation.

Background: An iatrogenic injury to the infrapatellar branch of the saphenous nerve (IPBSN) is a common precipitant of postoperative knee pain and hypoesthesia. Purpose: To locate potential safe zones for incision by observing the patterns and pathway of the IPBSN while examining the relationship of its location to sex, laterality, and leg length. Study Design: Descriptive laboratory study. Methods: A total of 107 extended knees from 55 formalin-embalmed cadaveric specimens were dissected. The nerve was measured from palpable landmarks: the patella at the medial (point A) and lateral (point B) borders of the patellar ligament, the medial border of the patellar ligament at the patellar apex (point C) and tibial plateau (point D), the medial epicondyle (point E), and the anterior border of the medial collateral ligament at the tibial plateau (point F). The safe zone was defined as 2 SDs from the mean. Results: Findings indicated significant correlations between leg length and height (r P = 0.832; P < .001) as well as between leg length and vertical measurements (≥45°) from points A and B to the IPBSN (r P range, 0.193-0.285; P range, .004-.049). Male specimens had a more inferior maximum distance from point A to the intersection of the IPBSN and the medial border of the patellar ligament compared with female specimens (6.17 vs 5.28 cm, respectively; P = .049). Right knees had a more posterior IPBSN from point F compared with left knees (-0.98 vs-0.02 cm, respectively; P = .048). The majority of knees (62.6%; n = 67) had a nerve emerging that penetrated the sartorius muscle. Additionally, 32.7% (n = 35) had redundant innervation, and 25.2% (n = 27) had contribution from the intermediate femoral cutaneous nerve (IFCN). Conclusion: We identified no safe zone. Significant innervation redundancy with a substantial contribution to the infrapatellar area from the IFCN was noted and contributed to the expansion of the danger zone. Clinical Relevance: The location of incision and placement of arthroscopic ports might not be as crucial in postoperative pain management as an appreciation of the variance in infrapatellar innervation. The IFCN is a common contributor. Its damage could explain pain refractory to SN blocks and therefore influence anesthetic and analgesic decisions.

Palliative Care Practice During the COVID-19 Pandemic: A Descriptive Qualitative Study of Palliative Care Clinicians.

CONTEXT: COVID-19 created unprecedented demand for palliative care at a time when in-person communication was highly restricted, straining efforts to care for patients and families. OBJECTIVES: To qualitatively explore the challenges presented by the COVID-19 pandemic from the perspective of palliative care clinicians. Specifically we sought to: 1) Describe the strategies adopted by palliative care clinicians to cope with new challenges including patient and clinician isolation, prognostication of an emergent disease, and rapidly rising numbers of severely ill patients; 2) Identify additions or adjustments to in-person and system-related palliative care training, methods, and tools made during pandemics. METHODS: This descriptive qualitative study utilized a thematic approach for data analysis of individual, semi-structured interviews with palliative care clinicians (n = 25). Codes, categories, and emerging themes were identified through an iterative, comparative method. Methods align with the Consolidated Criteria for Reporting Qualitative Research (COREQ) RESULTS: A theme of "Expanding the reach of palliative care for today and the future" was identified with three subthemes: 1) Redefining attitudes and hardship due to collective uncertainty, 2) Breaking with the past towards integrated concept of palliative care, and 3) Building capacity through primary palliative care training. CONCLUSION: COVID-19 forced hospital systems to consider the inclusion of palliative care in unforeseen ways due to an uncontrollable, unpredictable disease. Faced with unprecedented uncertainty, palliative care clinicians utilized strategies for integration and innovation across hospitals, particularly in intensive care units and emergency departments. A need to build capacity through increased primary palliative care access and training was identified.

Mapping a Danger Zone of the Dorsal Nerve of the Clitoris: Implications in Female Cosmetic Genital Surgery.

BACKGROUND: The literature regarding the route of the dorsal nerve of the clitoris is sparse and lacks surgical focus. With an increasing number of procedures being performed on the labia, it is important to elucidate the route and note any variation from normal of the nerve. METHODS: Fifty-one cadavers were dissected to yield 97 dorsal nerve of the clitoris samples. Measurements were taken from (1) the dorsal nerve of the clitoris penetration point of the perineal membrane to the urethra, (2) the nerve's penetration point of the perineal membrane to the pubic bone, (3) the angle of the clitoris to the branch point of the dorsal nerve of the clitoris, and (4) the branch point of the nerve to the distalmost point of the glans clitoris. Any anomalous branching patterns of the dorsal nerve of the clitoris were recorded and classified. RESULTS: The means and standard deviations of each measurement were used to create a surgical danger zone. The mean of each measurement was (1) 34.63 mm, (2) 5.74 mm, (3) -3.07 mm, and (4) 30.40 mm, respectively. In addition, six distinct branching patterns were observed, organized, and classified based on the location and number of branches observed. CONCLUSIONS: The dorsal nerve of the clitoris has multiple branching patterns and typically travels along the same course in most women. Further investigation of the course and three-dimensional position of the dorsal nerve of the clitoris is warranted to preserve sexual sensation as the frequency of procedures involving the female pudendum increases.

Role of lipid microdomains in P/Q-type calcium channel (Cav2.1) clustering and function in presynaptic membranes.

Lipid microdomains can selectively include or exclude proteins and may be important in a variety of functions such as protein sorting, cell signaling, and synaptic transmission. The present study demonstrates that two different voltage-gated calcium channels, which both interact with soluble N-ethyl-maleimide-sensitive fusion protein attachment protein receptor (SNARE) proteins but have distinct subcellular distributions and roles in synaptic transmission, are differently distributed in lipid microdomains; presynaptic P/Q (Cav2.1) but not Lc (Cav1.2) calcium channel subtypes are mainly accumulated in detergent-insoluble complexes. The immunoisolation of multiprotein complexes from detergent-insoluble or detergent-soluble fractions shows that the alpha1A subunits of Cav2.1 colocalize and interact with SNARE complexes in lipid microdomains. The altered organization of these microdomains caused by saponin and methyl-beta-cyclodextrin treatment largely impairs the buoyancy and distribution of Cav2.1 channels and SNAREs in flotation gradients. On the other hand, cholesterol reloading partially reverses the drug effects. Methyl-beta-cyclodextrin treatment alters the colocalization of Cav2.1 with the proteins of the exocytic machinery and also impairs calcium influx in nerve terminals. These results show that lipid microdomains in presynaptic terminals are important in organizing membrane sites specialized for synaptic vesicle exocytosis. The cholesterol-enriched microdomains contribute to optimizing the compartmentalization of exocytic machinery and the calcium influx that triggers synaptic vesicle exocytosis.
