We show that the basic dynamical rules of quantum physics can be derived from its static properties and the condition that superluminal communication is forbidden. More precisely, the fact that the dynamics has to be described by linear completely positive maps on density matrices is derived from the following assumptions: (1) physical states are described(More)
PURPOSE The detection of an infraclinical primary by tonsillectomy in case of cervical lymph node of an epidermoid carcinoma with unknown primary after a radical neck dissection, allows avoiding irradiation of the normal larynx. The aim of this study is to quantify the rate of tonsil primary to justify this procedure. METHODS AND MATERIALS From 1969 to(More)
Immunohistological investigations were performed on a series of samples from 37 patients with nasal polyps, 22 with chronic sinusitis, and 15 controls with healthy nasal and sinusal mucosa. Mean numbers of plasma- and mast cells were not different in the various groups. Immunoglobulin isotypes were always predominantly IgA and IgM; IgE were scarce.(More)
We report two cases of intra-auditory canal lipoma, presenting as acoustic neuroma, observed in respectively 45 and 53 year old patients. Cerebellopontine angle lipomas are unusual lesions, more exceptional than their intracranial counter-parts. The knowledge of these tumoral lesions and of their close relationships with cranial nerves incite to perform a(More)
Declining physical function is a major health problem for older adults as it is associated with multiple comorbidities and mortality. Exercise has been shown to improve physical function, though response to exercise is variable. Conversely, drugs targeting the renin–angiotensin system (RAS) pathway, including angiotensin-converting enzyme inhibitors (ACEi)(More)
In a prospective pilot study, we performed breast fine needle aspirations (FNAs) on 224 high-risk and 30 low-risk women and analyzed these aspirates for cytologic changes and biomarker abnormalities of aneuploidy and overexpressed estrogen receptor (ER), epidermal growth factor receptor (EGFR), p53 and HER-2/neu. High-risk women had a first-degree relative(More)
Recently a clinical prediction rule (CPR) for lumbar regional spinal thrust manipulation (STM) has shown predictive success in patients with back pain who met specific selection criteria. The purpose of this study was to compare the effectiveness of STM and mechanical diagnosis and therapy (MDT) in patients who are positive for the STM CPR. Following(More)
STUDY DESIGN Descriptive bibliometric analysis. BACKGROUND Content and bibliometric studies are useful for describing the publication patterns of a given profession, such as physical therapy, within the medical and allied health fields. However, few studies have conducted these analyses on specialty physical therapy journals. OBJECTIVES To conduct a(More)
Fine needle aspirates (FNA) from 106 high-risk women and 25 low-risk women were evaluated for overexpression of estrogen receptor (ER), epidermal growth factor receptor (EGFR), mutant p53, and HER-2/neu by immunocytochemistry, and for aneuploidy by image analysis. Aspirates were also classified cytologically as normal, apocrine metaplasia, epithelial(More)
