Using the Perimeter-Derived Diameter and Ellipticity Index of the Left Atrial Appendage Landing Zone to Predict Watchman Occluder Size
CONCLUSIONS: The longest diameter and the PDD methods predicted occluder size with a high degree of accuracy when the LAAs EI < 1.198; the PDD method is suggested to be a preferred method to treatAF.PMID:37708542

Case report of CT-guided lung biopsy complicated by air embolism
Undersea Hyperb Med. 2023 Third Quarter;50(3):273-281.ABSTRACTRATIONALE: Cerebral arterial air embolism is a rare but potentially fatal complication of computed tomography (CT) guided lung biopsy. Hyperbaric oxygen (HBO2) is the first line of treatment for arterial gas embolism and needs to be administered immediately after the event. Early HBO2 can reduce the mortality rate of cerebrovascular air embolism.PATIENT CONCERNS: A 65-year-old woman was diagnosed with a pulmonary nodule with a diameter of approximately 0.8 cm in the right lower lung. The patient developed consciousness, convulsions, and arrhythmia after CT-guide...

Benefits and drawbacks of CT scan as a triple rule-out exam in acute chest pain to exclude acute coronary syndrome, pulmonary embolism and aortic dissection
Ann Cardiol Angeiol (Paris). 2023 Sep 11;72(5):101641. doi: 10.1016/j.ancard.2023.101641. Online ahead of print.ABSTRACTChest pain is one of the major causes for admission in the Emergency Room in most countries and one of the principal reasons for urgent consultation with a cardiologist or a general practitioner. After clinical examination and initial biological measurements, substantial patients require further explorations. CT scan allows the search for pulmonary embolism in the early stage of pulmonary arteries iodine contrast exploration. During the same exam at the systemic arterial phase, the search for aortic disse...

Nondeformed Ultrasound Image Production Method for Ultrasound-Guided Radiotherapy
Conclusion: The pixel displacement-based deformation correction method can solve the limitation imposed by image deformation on image alignment in US-guided radiotherapy. Compared with USdef, the alignment results of USrev with CT were better.PMID:37700675 | DOI:10.1177/15330338231194546

Clinical Observation and Analysis of Thyroglossal Duct Cyst Carcinoma: A Report of 5 Cases
This study aimed to address these gaps by analyzing and summarizing the clinical features of 5 cases of papillary carcinoma arising in thyroglossal duct cysts (TGDC).Five patients with papillary carcinoma in TGDC treated by modified Sistrunk's procedure were included. Their clinical manifestation, physical examination findings, iconography, pathological findings, treatment, and outcomes were analyzed in aiding the diagnosis and treatment of TGDCCa. Immunohistochemistry was used to confirm the papillary carcinoma subtype. The BRAFV600E mutation was detected in 2 patients. No evidence of cancer recurrence, distant metastases...

Dose-Dependent Testicular Injury and Recovery after Total-Body Irradiation in Rhesus Monkeys
We examined the testes from 143 irradiated and control male rhesus monkeys, who were part of the Radiation Late Effects Cohort over a four-year period. Irradiated animals were exposed to doses ranging from 3.5 to 8.5 Gy of total-body irradiation. The testes were assessed using computed tomography (CT) volumetry, serum testosterone, and histology for deceased members of the cohort. Irradiated animals exhibited dose-dependent testicular atrophy as well as decreased serum testosterone during the winter breeding season when compared to age-matched unirradiated controls. No significant difference in summer testosterone levels w...

Improvement in Lung Clearance Index and Chest CT Scores with Elexacaftor/Tezacaftor/Ivacaftor Treatment in People with Cystic Fibrosis Aged 12 Years and Older - The RECOVER Study
CONCLUSIONS: ETI is associated with substantial improvements in LCI2.5, spirometry and PRAGMA-CF CT scores in people with CF aged 12 years and older. ETI led to improved nutrition and quality of life. People in the F508del/F508del group have significantly lower sweat chloride on ETI treatment compared to the F508del/MF group.

Proton range uncertainty caused by synthetic computed tomography generated with deep learning from pelvic magnetic resonance imaging
CONCLUSION: The sCT model was shown to be robust, i.e., had a low random model error. However, further investigation to reduce and even predict and manage systematic error is still needed for future MRI-only proton therapy.PMID:37703314 | DOI:10.1080/0284186X.2023.2256967

Miliary tuberculosis mimicking COVID-19 multisystemic inflammatory syndrome in children
We present the case of a 6-year-old girl with no remarkable history who had recurrent fever for 3 months. She was initially diagnosed with, and treated for, refractory multisystem inflammatory syndrome in children (MIS-C). When the study was extended to other differential diagnoses, thoraco-abdominopelvic computed tomography revealed miliary pulmonary nodules in addition to lymph nodes and spleen lesions. Magnetic resonance imaging of the brain revealed multiple tuberculomas. The tuberculin test results were positive. The course of the disease was favorable under quadruple therapy.PMID:37704522 | DOI:10.1016/j.arcped.2023.08.003

Does unenhanced computerized tomography as imaging standard post-retrograde intrarenal surgery paradoxically reduce stone-free rate and increase additional treatment for residual fragments? Outcomes from 5395 patients in the FLEXOR study by the TOWER group
CONCLUSIONS: CT is the only reliable imaging to assess the burden of RFs following RIRS and urologist should consider at least one CT scan to determine the same and definitely plan reintervention only based on CT rather than ultrasound and X-ray combination.PMID:37701535 | PMC:PMC10493056 | DOI:10.1177/17562872231198629

Association of Coronary Artery Calcium Detected by Routine Ungated CT Imaging With Cardiovascular Outcomes
CONCLUSIONS: Incidental CAC ≥100 was associated with an increased risk of all-cause death and adverse cardiovascular outcomes, beyond traditional risk factors. DL-CAC from routine non-ECG-gated CTs identifies patients at increased cardiovascular risk and holds promise as a tool for opportunistic screening to facilitate earlier intervention.PMID:37704309 | DOI:10.1016/j.jacc.2023.06.040

Food texture and vitamin D influence mouse mandible form and molar roots
Anat Rec (Hoboken). 2023 Sep 13. doi: 10.1002/ar.25315. Online ahead of print.ABSTRACTIndustrialization influenced several facets of lifestyle, including softer nutrient-poor diets that contributed to vitamin D deficiency in post-industrzialized populations, with concomitantly increased dental problems. Here we simulated a post-industrialized diet in a mouse model to test the effects of diet texture and vitamin D level on mandible and third molar (M3) forms. Mice were raised on a soft diet with vitamin D (VitD) or without it (NoD), or on a hard diet with vitamin D. We hypothesized that a VitD/hard diet is optimal for norma...
