We report the case of an elderly woman with cervical deformity due to a large diffuse goiter and predictive data for a difficult airway, alteration of all thyroid hormone levels and an exposed wrist fracture. After a pre-block ultrasound scan, the supraclavicular approach to the brachial plexus was selected because the gland growth was in the anterior to posterior axis, without displacement of ...

This paper addresses the issue of non-invasive investigation and functional assessment of pulmonary airways reconstructed from multi detector computed tomography clinical acquisitions. Such an analysis combines accurate 3D meshing of the inner bronchial wall surface and navigation and interactivity tools based on a robust central axis representation. A reliable endoluminal investigation of airw...

Subcortical lesions have been simultaneously implicated in both real and simulated movement deficits. However, the analysis of the simulated opposition axis in precision grasping reveals that, in individuals with idiopathic bilateral Parkinson' disease motor imagery is impaired and that execution of overt movements is spared. This constitutes the first lesion observation congruent with the anat...

The quadricuspid pulmonary valve is a rare congenital anomaly. It tends to be clinically quiescent. Its diagnosis by two-dimensional echocardiography could be very difficult because of the anatomical features. We report on the echocardiographic findings of a 66-year-old female patient with mitral and aortic regurgitation of rheumatic origin and severe pulmonary hypertension. There was an aneuri...

BACKGROUND AND PURPOSE Whether tibial torsion affects the positioning of extramedullary instrumentation and is a possible factor in malalignment of the tibial component in total knee arthroplasty (TKA) is unknown. We assessed the influence of tibial torsion on distal alignment of extramedullary systems for TKA, using the center of the intermalleolar distance as anatomical reference at the ankle...

Proprioceptive feedback is thought to play a significant role in controlling both lumbopelvic and intervertebral orientations. In the lumbar spine, a vertebra's positional history along the dorsal-ventral axis has been shown to alter the position, movement, and velocity sensitivity of muscle spindles in the multifidus and longissimus muscles. These effects appear due to muscle history. Because ...

A case study based on both simulated and actual images was performed. The simulated anatomical phantom used was obtained from CT data of a human leg provided by the “Visible Human” project. A virtual orthopedic nail was added to the data set and projection images were obtained using a simulated irradiation procedure. An actual phantom made of wax having an orthopedic nail inserted was also imag...

Craniovertebral junction surgery involves an appropriate philosophical, biomechanical and anatomical understanding apart from high degree of technical skill and ability of controlling venous and arterial bleeding. The author presents his 30-year experience with treating complex craniovertebral junction instability related surgical issues. The facets of atlas and axis form the primary site of mo...

urtica dioica l. is an iranian native pharmacological plant for which little attention has been paid to the anatomical structure. medical applications of this plant include diabetes therapy, digestive improvement, anemia and kidney disease therapy. because climatic conditions can affect the anatomical structure which in turn affects pharmacological compositions, research on the anatomy of this ...

case presentation a 30-year-old male patient with a history of severe, throbbing, constant pain in the lower mandibular molars was referred to the department of endodontics of hamedan dental university. the patient’s medical history was noncontributory. the buccal object rule (same-lingual opposite-buccal technique) confirmed the additional root as a distolingual root (radix entomolaris). follo...
