Aim
Sarcopenia has been increasingly reported as a prognostic factor for outcome in settings such as cirrhosis, liver transplantation, and emergent surgery. We aimed to elucidate the significance of sarcopenia in severe blunt trauma patients.
Methods
We retrospectively analyzed 84 patients emergently admitted to the intensive care unit at Kyushu University Hospital (Fukuoka, Japan) from May 2012 to April 2015. We assessed the amount of skeletal muscle present according to computed tomography and its relevance to ventilation‐free days, patients' length of stay in the intensive care unit, and 28‐day mortality.
Results
Twenty‐five (29.7%) patients were defined as sarcopenic. Sixteen (19.7%) patients required 15 days or more in the intensive care unit. The major reason was a prolonged ventilation requirement due to flail chest (n = 7) or pneumonia (n = 3). Sarcopenic patients' stays in intensive care were significantly longer than those of non‐sarcopenic patients (18.7 versus 6.4 days, respectively; P < 0.001). Univariate and multivariate analyses showed sarcopenia to be a significant risk factor for prolonged intensive care unit stay.
Conclusion
Sarcopenia is a risk factor that predicts prolonged intensive care unit stay in high‐energy blunt trauma patients.
Objectives:
To characterize the real size and morphology of tracheas in childhood for the optimal selection of endotracheal tube.
Design:
A retrospective cohort study of pediatric patients who received CT scan of the cervical spine from July 2011 to March 2018. Cross-sectional CT images vertical to trachea were reconstructed and the accurate tracheal diameters were measured. The validity of the traditional age-based formula for predicting the endotracheal tube size was assessed for the best fit to trachea.
Setting:
Tertiary Emergency and Critical Care Center of Kyushu University Hospital.
Patients:
Children, who are 1 month to 15 years old, received CT scan of the cervical spine.
Interventions:
None.
Measurements and Main Results:
We enrolled 86 children with median age of 53 months. The cross-sectional shape of pediatric trachea was circular at the cricoid level and elliptical at the infraglottic level. The narrowest part of pediatric trachea was the transverse diameter at the infraglottic level at any age. Significant positive correlation between age and the narrowest diameter was observed. When compared the transverse diameter at the infraglottic level with the outer diameter of endotracheal tubes, uncuffed endotracheal tubes selection based on the traditional age-based formula ran a significant risk of oversized endotracheal intubation until 10 years old compared with cuffed endotracheal tubes selection (60.0% vs 23.8%; p < 0.05).
Conclusions:
These findings indicate the safety and efficacy of cuffed endotracheal tubes in infants and children and the reconsideration for the airway management in pediatric anesthesia and intensive care.
BackgroundStreptococcus pyogenes is an uncommon pathogen of purpura fulminans, and the pathogenesis of S. pyogenes-purpura fulminans remains unclear because of paucity of cases. We reported a pediatric case of S. pyogenes-purpura fulminans with literature review of the disease.Case presentationA 3-year-old boy showed limping, lethargy and acral gangrene within 24 h. A diagnosis of S. pyogenes-purpura fulminans was made for bacterial isolation from throat and peripheral blood. Intensive therapy led to a survival with amputation of the left distal metatarsal bone, and normal development. The isolated M12 carried no mutation of csrS/R or rgg. Thrombophilia or immunodeficiency was excluded.DiscussionTwelve-reported cases (9 pediatric and 3 elderly) of S. pyogenes-purpura fulminans started with shock and coagulopathy. Five patients age < 8 years had no underlying disease and survived. One youngest and two immunocompromised patients died.ConclusionStreptococcus pyogenes-acute infectious purpura fulminans is a distinctive rare form of aggressive GAS infections.
We report a case of juvenile xanthogranuloma (JXG) having progressive pancytopenia for 6 months until the proliferating skin lesions. A 2-month-old infant presented recurrent fever, anemia, and hepatosplenomegaly mimicking hemophagocytic lymphohistiocytosis (HLH) or juvenile myelomonocytic leukemia (JMML). At 8 months of age, the biopsy of a growing papule on the elbow made the diagnosis. Bone marrow (BM) specimens showed clustering foamy cells including hemophagocytosis by histiocytes. Treatment with etoposide followed by vinblastine plus prednisolone (PSL) therapy improved the disease. Although JXG is a benign non-Langerhans cell histiocytosis, the multisystem-visceral form should be considered as a potential aggressive disease when associated with BM failure in early infancy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
