Imaging Features and Complications of Facial Cosmetic Procedures.

Facial aesthetic procedures have become increasingly popular and complex, making knowledge of facial anatomy crucial for achieving desired outcomes without complications. Some of the most common procedures include blepharoplasty, bichectomy, face-lifts, facial implants, thread lifting, and fillers. Blepharoplasty and bichectomy are surgical procedures that respectively aim to restore youthful contours to the periorbita and create a slimmer lower face by removing Bichat fat from the maxillofacial region.

Adverse Radiation Therapy Effects in the Treatment of Head and Neck Tumors.

Whether used as a single modality or as part of a combined approach, radiation therapy (RT) plays an essential role in the treatment of several head and neck malignancies. Despite the improvement in radiation delivery techniques, normal structures in the vicinity of the target area remain susceptible to a wide range of adverse effects. Given their high incidence, some of these effects are referred to as expected postradiation changes (eg, mucositis, sialadenitis, and edema), while others are considered true complications, meaning they should not be expected and can even represent life-threatening conditions (eg, radionecrosis, fistulas, and radiation-induced neoplasms).

Postoperative Imaging of the Temporal Bone.

The anatomy of the temporal bone is complex, and postoperative imaging evaluation of this bone can be challenging. Surgical approaches to the temporal bone can be categorized didactically into tympanoplasty and ossicular reconstruction, mastoidectomy, and approaches to the cerebellopontine angle and internal auditory canal (IAC). In clinical practice, different approaches can be combined for greater surgical exposure.

In comparison to the myocardial perfusion scintigraphy, a treadmill stress test is a viable, efficient and cost effective option to predict cardiovascular events in elderly patients.

Objective: To define the prognostic value and cost-effectiveness of the treadmill stress test (TST) in comparison to the dipyridamole myocardial perfusion scintigraphy (DIP), in individuals > or = 75 years of age.

Methods: Consecutive and prospective assessment of 66 patients (40% male) aged 81 +/- 5 years of which 57% were hypertensive, 38% had dyslipidemia and 28% were diabetics. The Bruce protocol was adapted for a tilt treadmill and the TST prognostic value was obtained using the Duke treadmill score.

Exercise stress testing is useful, safe, and efficient even in patients aged 75 years or older.

Objective: To describe the clinical and hemodynamic variables obtained with exercise testing in elderly patients SW >75 years.

Methods: This study assessed 100 patients aged 75-94 years (80+/-4 years) undergoing symptom-limited exercise testing, 65% of whom were asymptomatic, 25% had nonanginal chest pain, and 10% had typical precordialgia. Of the 100 patients, 32% were males, 50% were hypertensive, 36% were dyslipidemic, 14% were diabetic, and 9% had had previous coronary artery disease.
