BACKGROUND Enchondromatosis represent a heterogenous group of disorders. Spranger et al attempted a classification into 6 types: Ollier disease, Maffuci syndrome, metachondromatosis, spondyloenchondrodysplasia, enchondromatosis with irregular vertebral lesions, and generalized enchondromatosis. Halal and Azouz added 3 tentative categories to the 6 in the classification of Spranger et al. CASE...

Space Situational Awareness (SSA) involves detecting, tracking, identifying and characterizing resident space objects (RSOs). Electro-optical measurements can be used to estimate important characteristics, such as the size, shape, configuration, rotational dynamics (attitude and angular velocity), and surface properties such as specular and diffuse albedo (reflectivity) of a resident space obje...

BACKGROUND Much of what is known about human monocytic ehrlichiosis (HME) is based upon studies with adult patients. PURPOSE To review our experience with HME to better understand the epidemiology, clinical manifestations, and outcome of this disease in children. METHODS Demographic, clinical, and laboratory data were gathered after review of the medical records of patients identified with ...

The purpose of this study was to investigate the influence of sodium bicarbonate on the physicochemical properties of controlled release hot-melt extruded (HME) tablets containing Eudragit RS PO and/or Eudragit E PO. Acetohydroxamic acid and chlorpheniramine maleate were used as model drugs. Sodium bicarbonate was incorporated into the tablet formulations and the drug release properties and buo...

OBJECTIVES/HYPOTHESIS Assessment of immediate postoperative airway humidification after total laryngectomy (TLE), comparing the use of an external humidifier (EH) with humidification through a heat and moisture exchanger (HME). STUDY DESIGN Randomized controlled trial (RCT). METHODS Fifty-three patients were randomized into the standard (control) EH (N = 26) or the experimental HME arm (N =...

OBJECTIVE To assess the endotracheal temperature and humidity and clinical effects of 2 models of a new heat and moisture exchanger (HME): Rplus, which has regular breathing resistance, and Lplus, which has lower breathing resistance. METHODS We measured endotracheal temperature and humidity in 10 laryngectomized patients, for 10 min each, with and without the HMEs. We sequentially tested 4 H...

INTRODUCTION When endotracheal intubation is required during ventilatory support, the physiologic mechanisms of heating and humidifying the inspired air related to the upper airways are bypassed. The task of conditioning the air can be partially accomplished by heat-and-moisture exchangers (HMEs). OBJECTIVES To evaluate and compare with respect to imposed resistance, different types/models of...

A 48-year-old man was referred to our unit for assessment of recurring episodes of painful torticollis. Family and past histories were unremarkable. There was no traumatic antecedent. During the previous three years he had experienced several episodes of torticollis and painful cervical movements without radiculopathy. His neurological examination was normal, except for a head tilt, decrease ra...
