Verification of the Optimal Chest Compression Depth for Children in the 2015 American Heart Association Guidelines: Computed Tomography Study
This study evaluated the appropriateness of these two types by comparing their safeties in chest compression depth simulated by CT. Design: Retrospective study with data analysis conducted from January 2005 to June 2015 Setting: Regional emergency center in South Korea. Patients: Three hundred forty-nine pediatric patients 1–9 years old who had a chest CT scan. Interventions: Simulation of chest compression depths by CT. Measurements and Main Results: Internal and external anteroposterior diameter of the chest and residual internal anteroposterior diameter after simulation were measured from CT scans. The safe cutoff levels were differently applied according to age. One-third external anteroposterior diameters were compared with an upper limit of chest compression depth recommended for adults. Primary outcomes were the rates of overcompression to evaluate safety. Overcompression was defined as a negative value of residual internal anteroposterior diameter—age-specific cutoff level. Using a compression of 5-cm depth simulated by chest CT, 16% of all children (55/349) were affected by overcompression. Those 1–3 years old were affected more than those 4–9 years old (p
A 17 year old girl presented with a progressively increasing swelling in her neck since 9 months. On examination a2*3 cm, firm, pulsatile swelling was felt in the left anterior triangle. The CT scan of the mass was suggestive of a carotid body tumor and urinary cathecholamines were negative. The mass was excised completely.
CONCLUSIONS AND CLINICAL RELEVANCE Results indicated that for a 64-slice CT scanner, the optimal protocol for the acquisition of CT images of the dentition in alpacas was a sequential scan with a slice thickness of 1.25 mm. PMID: 29466047 [PubMed - in process]
Summary Non‐invasive imaging techniques like X‐ray computed tomography have become very popular in zoology, as they allow for simultaneous imaging of the internal and external morphology of organisms. Nevertheless, the effect of different staining approaches required for this method on samples lacking mineralized tissues, such as soft‐bodied invertebrates, remains understudied. Herein, we used synchrotron radiation‐based X‐ray micro‐computed tomography to compare the effects of commonly used contrasting approaches on onychophorans – soft‐bodied invertebrates important for studying animal evolution. Repr...
CONCLUSIONS PF is a potential agent against osteolysis-related diseases caused by excessive osteoclast activity. PMID: 29459582 [PubMed - in process]
Conclusions: QCT metrics demonstrate stronger correlations with FEV1 and are better predictors of pulmonary function than SQS. SQS performs moderately well in bilateral LTx, but poorly on unilateral LTx. In unilateral LTx, QCT metrics from the transplanted lung are better predictors of FEV1 than QCT metrics from the nontransplanted lung.
Conclusion This study provides an innovative method for assessing the symmetry of the zygomatic bone based on surface analysis. Results may provide useful indications for the reconstruction of zygomatic bones in maxillofacial surgery.
AbstractPurposeUsing a cementless femoral stem in total hip arthroplasty (THA), optimal filling of the proximal femoral metaphyseal volume (PFMV) and restoration of the extramedullary proximal femoral (PF) parameters (i.e., femoral offset (FO), neck length (FNL), and head height (FHH)) constitute key goals for optimal hip biomechanics, functional outcome, and THA survivorship. However, almost 30% of mismatch between the PF anatomy and implant geometry of the most widely implanted non-modular cementless femoral stem has been demonstrated in a computed tomography scan (CT scan) study. Therefore, this anatomic study aimed to ...
ConclusionOur case report contributes to the accruing evidence on the effectiveness of denosumab for the treatment of spinal ABCs. However, long-term safety, risk of recurrence, optimal duration of treatment and consistency of denosumab are yet to be determined.
Pancreatic schwannomas are uncommon. About 60% of pancreatic schwannomas develop cystic lesions, and the differential diagnosis from other cystic pancreatic tumors is difficult. A 43-year-old man presented for evaluation of liver dysfunction detected during a medical checkup. Blood testing detected obstructive jaundice. A computed tomography scan revealed a well-defined polycystic tumor of about 5 cm at the pancreatic head. We performed surgical resection to treat the patient ’s symptoms and facilitate long-term management. Histopathological examination revealed spindle-shaped cells. Immunohistochemical studies showe...
Conclusions We found that T SUVmax, stage, and para-aortic lymph node status assessed by FDG-PET were independent prognostic factors of DFS, whereas only T SUVmax correlated with OS.
