Magnetic resonance imaging clearly identifies the anterolateral ligament of the knee in slightly more than half of cases, being partially visible in most of them. In all cases, a tibial insertion is characterized.

The user-friendly 308-nm excimer laser allows targeted treatments of localized vitiligo.

Ischiofemoral impingement is a syndrome defined by hip pain associated with narrowing of the space between ischial tuberosity and lesser trochanter. This phenomenon leads to abnormalities of the quadratus femoris muscle, ranging from deformity and edema to tears and atrophy. This review article presents an up-to-date discussion and imaging findings of ischiofemoral impingement, along with its related anatomy, clinical presentation, differential diagnosis and treatment.

In a randomized, double-blind study, cystic fibrosis patients 11-30 years of age with an acute exacerbation of their pulmonary disease were treated with either ticarcillin-tobramycin, azlocillin-tobramycin, or azlocillin-placebo for 10 days. There was significant improvement in Shwachman scores and pulmonary function tests. Concentrations of sputum bacteria were significantly reduced, but after therapy patients had a mean of 10(7) bacteria/ml of sputum. Pseudomonas was transiently eliminated in only one patient. The three regimens had similar impacts on pulmonary function and sputum bacterial concentration. Antibiotic resistance was noted more frequently in the azlocillin-placebo group, but this trend was not statistically significant. Improvement in pulmonary function did not correlate with bacteriological response. Four weeks after discharge, 62% of the improvement in forced expiratory volume in one second and 75% of the improvement in vital capacity remained, but concentrations of sputum bacteria had returned to pretreatment levels, and antibiotic-resistant bacteria persisted.

FDG PET/CT is an accurate technique for detection of skeletal metastases, and is superior to bone scan, especially in the spine and pelvis.

Paravertebral soft-tissue changes, when present, may be considered a viable target for biopsy in cases of diskitis-osteomyelitis, even in the absence of a paravertebral abscess.

Vitiligo, particularly in darker skinned individuals, is a psychosocial disaster. With patient education, proper therapeutic selection and persistence, favorable repigmentation can be achieved in the majority of individuals with vitiligo. Attention to the activity state of the disease, the type, location and extent of the vitiligo must be carefully balanced against the patient's expectations, time commitment and assumption of risks. In this review, Dr Taneja succinctly summarizes the wide range of therapeutic options available today for the vitiligo patient.

Magnetic resonance neurography is a high-resolution imaging technique that allows evaluating different neurological pathologies in correlation to clinical and the electrophysiological data. The aim of this article is to present a review on the anatomy of the lumbosacral plexus nerves, along with imaging protocols, interpretation pitfalls, and most common pathologies that should be recognized by the radiologist: traumatic, iatrogenic, entrapment, tumoral, infectious, and inflammatory conditions. An extensive series of clinical and imaging cases is presented to illustrate key-points throughout the article.
