RESUMEN
Vaccine-preventable diseases (VPDs) such as measles and pertussis are becoming more common in the United States. This disturbing trend is driven by several factors, including the antivaccination movement, waning efficacy of certain vaccines, pathogen adaptation, and travel of individuals to and from areas where disease is endemic. The anesthesia-related manifestations of many VPDs involve airway complications, cardiovascular and respiratory compromise, and unusual neurologic and neuromuscular symptoms. In this article, we will review the presentation and management of 9 VPDs most relevant to anesthesiologists, intensivists, and other hospital-based clinicians: measles, mumps, rubella, pertussis, diphtheria, influenza, meningococcal disease, varicella, and poliomyelitis. Because many of the pathogens causing these diseases are spread by respiratory droplets and aerosols, appropriate transmission precautions, personal protective equipment, and immunizations necessary to protect clinicians and prevent nosocomial outbreaks are described.

OBJECTIVE: In this review, we define learning goals and recommend competencies concerning focused basic critical care ultrasound (CCUS) for critical care specialists in training. DESIGN: The narrative review is, and the recommendations contained herein are, sponsored by the Society of Critical Care Anesthesiologists. Our recommendations are based on a structured literature review by an expert panel of anesthesiology intensivists and cardiologists with formal training in ultrasound. Published descriptions of learning and training routines from anesthesia-critical care and other specialties were identified and considered. Sections were written by groups with special expertise, with dissent included in the text. RESULTS: Learning goals and objectives were identified for achieving competence in the use of CCUS at a specialist level (critical care fellowship training) for diagnosis and monitoring of vital organ dysfunction in the critical care environment. The ultrasound examination was divided into vascular, abdominal, thoracic, and cardiac components. For each component, learning goals and specific skills were presented. Suggestions for teaching and training methods were described. DISCUSSION: Immediate bedside availability of ultrasound resources can dramatically improve the ability of critical care physicians to care for critically ill patients. Anesthesia--critical care medicine training should have definitive expectations and performance standards for basic CCUS interpretation by anesthesiology--critical care specialists. The learning goals in this review reflect current trends in the multispecialty critical care environment where ultrasound-based diagnostic strategies are already frequently applied. These competencies should be formally taught as part of an established anesthesiology-critical care medicine graduate medical education programs.

We report a case of a patient undergoing esophagectomy for end-stage achalasia, a rare condition associated with potentially catastrophic ventilatory and circulatory complications. The complexity of the case necessitated preoperative planning with the surgical specialist, development of a novel algorithm for airway management, and careful implementation of our plan. Isolation of the lungs from the esophagus presented unique challenges due to not only the anatomic derangements that are the hallmark of this disease process but also an unusual anatomic finding seen in this patient.
RESUMEN
RATIONALE: The mechanistic basis for cardiac and renal dysfunction in sepsis is unknown. In particular, the degree and type of cell death is undefined. OBJECTIVES: To evaluate the degree of sepsis-induced cardiomyocyte and renal tubular cell injury and death. METHODS: Light and electron microscopy and immunohistochemical staining for markers of cellular injury and stress, including connexin-43 and kidney-injury-molecule-1 (Kim-1), were used in this study. MEASUREMENTS AND MAIN RESULTS: Rapid postmortem cardiac and renal harvest was performed in 44 septic patients. Control hearts were obtained from 12 transplant and 13 brain-dead patients. Control kidneys were obtained from 20 trauma patients and eight patients with cancer. Immunohistochemistry demonstrated low levels of apoptotic cardiomyocytes (<1-2 cells per thousand) in septic and control subjects and revealed redistribution of connexin-43 to lateral membranes in sepsis (P < 0.020). Electron microscopy showed hydropic mitochondria only in septic specimens, whereas mitochondrial membrane injury and autophagolysosomes were present equally in control and septic specimens. Control kidneys appeared relatively normal by light microscopy; 3 of 20 specimens showed focal injury in approximately 1% of renal cortical tubules. Conversely, focal acute tubular injury was present in 78% of septic kidneys, occurring in 10.3 ± 9.5% and 32.3 ± 17.8% of corticomedullary-junction tubules by conventional light microscopy and Kim-1 immunostains, respectively (P < 0.01). Electron microscopy revealed increased tubular injury in sepsis, including hydropic mitochondria and increased autophagosomes. CONCLUSIONS: Cell death is rare in sepsis-induced cardiac dysfunction, but cardiomyocyte injury occurs. Renal tubular injury is common in sepsis but presents focally; most renal tubular cells appear normal. The degree of cell injury and death does not account for severity of sepsis-induced organ dysfunction.
