Comparison of immediate and conventional loading protocols with respect to marginal bone loss around implants supporting mandibular overdentures: A systematic review and meta-analysis

ConclusionThe MBLCs of immediately-loaded implants for mandibular IODs seems comparable to those of conventional loading.

Publication date: Available online 6 January 2020Source: Radiation Physics and ChemistryAuthor(s): Seyed Milad Vahabi, Mojtaba Shamsaei ZafarghandiAbstractAccording to the principles of radiation protection, the patient and personnel dose should be decreased to a reasonably achievable level. Therefore, it is essential to use reliable dosimeters in the radiation dosimetry course. One of these dosimeters is an extrapolation chamber. It is a plane-parallel ion chamber (PPIC), which its sensitive volume can be varied. In this paper, the performance of an extrapolation chamber has been evaluated in 60–200 kVp X-rays. It...

The recommended imaging tests for nonatherosclerotic peripheral artery disease include ultrasound duplex Doppler (ultrasound), intravascular ultrasound (inside arteries), MR angiography (MRA; MRI of arteries with or without intravenous [IV] contrast dye), CT angiography (CTA; CT scan of arteries using IV contrast), arteriography (x-rays of arteries with IV contrast).

ConclusionIn such cases, whenever the conventional imaging modalities like the X-rays such as intra oral peri-apical views and orthopantomograms are unavailable, or where use of ionizing radiation is a grave concern (especially in children and pregnant patients), ultrasonography offers a non-invasive diagnostic imaging method which helps in diagnosis of the condition and also helps in supplementing the clinical information, thereby helping in better understanding of the underlying condition.

ConclusionsThis study showed that a substantial number of patients with partially stable and unstable pelvic ring fractures have an increased cancer risk due to trauma-related medical imaging. Physicians should be aware of the amount of radiation their patients are exposed to, and minimize imaging related increase of cancer risks during initial assessment, treatment and follow-up.

Authors: Zhang M, Fan Q, Lei Y, Thapa B, Padula G Abstract BACKGROUND: Versa HD linear accelerators (linacs) are used for stereotactic radiosurgery treatment. However, the mechanical accuracy of such systems remains a concern. OBJECTIVE: The purpose of this study was to evaluate the accuracy of an Elekta Versa HD linac. METHODS: We performed measurements with a ball bearing phantom to calculate the rotational isocenter radii of the linac's gantry, collimator, and table, and determine the relative locations of those isocenters. We evaluated the accuracy of the cone-beam computed tomography (CBCT) guidance wi...

ConclusionTrauma on the neck leads most frequently to fractures of the superior horn of the thyroid cartilage and second most to fractures in the greater horn of the hyoid bone. (Forensic) radiologists should be aware of uncommon fracture locations, anatomical variations, and dislocations in the hyoid-larynx complex.

CONCLUSION: The approach is simple with minimal blood loss as it does not involve splitting or cutting of trapezius, rhomboid major or subscapularis muscles. PMID: 31916491 [PubMed - in process]

Conclusions Based on the literature, we recommend a period of nonoperative management before surgery in undisplaced nonunions. In displaced nonunions, open reduction and internal fixation ± bone grafting is necessary. In pediatric scaphoid fractures, similar to adult cases, we identified that suspicious scaphoid fractures should be considered for initial immobilization, and repeat X-rays and early magnetic resonance imaging (MRI) or computed tomography (CT) scans should be considered at follow-up. Immobilization time and type of plaster should be appropriate in relation to the fracture site, simil...

CONCLUSION:  Since LC was present in almost 40% of the severely injured and was related to higher morbidity, LC should be detected and managed at the earliest possible time. Proper follow-ups employing chest X-rays and computed tomography (CT) scans are recommended. PMID: 31858497 [PubMed - as supplied by publisher]
