Dimethyl sulfoxide “activated” by oxalyl chloride at low temperatures in methylene chloride
reacts rapidly with alcohols to give alkoxysulfonium salts, convertible to carbonyls in high to …

Selected examples of the use of activated dimethyl sulfoxide reagents in organic synthesis
are discussed with emphasis being placed on low tem-perature studies conducted in the …

PURPOSE: To compare the abilities of magnetic resonance (MR) imaging and computed
tomography (CT) in detection of lymph node metastasis from head and neck squamous cell …

OBJECTIVE. This study was undertaken to create an imaging-based classification for the
lymph nodes of the neck that will be readily accepted by clinicians, result in consistent nodal …

Over the past 18 years, numerous classifications have been proposed to distinguish among
the diverse nodal levels. Some classifications have used surgical landmarks, others physical …

“Activation” of dimethyl sulfoxide (Me2SO) by oxalyl chloride (OC) at low temperatures in
methylene chloride yields an unstable intermediate that instantaneously loses C02 and CO. …

Joubert syndrome is characterized by episodic hyperpnea and apnea, developmental delay,
hypotonia, truncal ataxia, ophthalmologic abnormalities, and vermian dysgenesis. We …

Objectives/Hypothesis: To discuss our experience with the diagnostic evaluation in patients
with squamous cell carcinomas (SCCAs) of the head and neck metastatic to the cervical …

Purpose: To analyze the pretreatment imaging findings and outcome of patients with
perineural spread of squamous or basal cell carcinoma of the face and scalp treated with …

Purpose. To evaluate the outcome and patterns of relapse in patients treated for skin carcinoma
of the head and neck with either microscopic or clinical perineural invasion. Methods …
