Elastolytic matrix metalloproteinases (MMPs) have been implicated in the pathogenesis of abdominal aortic aneurysms (AAA), a disorder characterized by chronic aortic wall inflammation and destruction of medial elastin. The purpose of this study was to determine if human macrophage elastase (HME; MMP-12) might participate in this disease. By reverse transcription-polymerase chain reaction, HME m...
BACKGROUND Heat and moisture exchangers (HME) are often used to maintain humidity of breathing circuits during anesthesia. It is also known to increase dead space ventilation in respiratory distress syndromes. However, the effect of a pediatric HME in healthy pediatric patients has not yet been clarified. The purpose of this study was to evaluate the effect of a pediatric HME on dead space in h...
BACKGROUND total laryngectomy has several consequences such as loss of the laryngeal voice and alterations in the respiratory system. AIM to evaluate the influence of a tracheostoma humidifier (heat moisture exchanger - HME) on the control of lung secretion and esophageal and tracheoesophageal vocal quality in patients with total laryngectomy. METHOD nine male individuals, aged between 46 t...
EFFECTS OF HEAT AND MOISTURE EXCHANGERS DESIGNED TO ALLOW AEROSOL DELIVERY ON AIRFLOW RESISTANCE AND AEROSOL DEPOSITION By William Sonny Bowers Introduction: Several problems arise when HMEs are used while giving aerosolized medication including increased airway resistance (Raw) or the need to open the ventilator circuit. Recently, heat and moisture exchangers designed to allow aerosol delivery...
OBJECTIVE To compare the degree of bacterial circuit colonization, frequency of ventilator-associated pneumonia (VAP), character of respiratory secretions, rewarming of hypothermic patients, disposable costs, and air flow resistance in intensive care patients ventilated using either a heat and moisture exchanger (HME) or hot water (HW) humidifier circuit. DESIGN A prospective, randomized blin...
Bone exostosis has long been described in the literature, appearing in most cases as a torus palatinus or mandibularis. These two variations are relatively common and affect approximately 30% of the world's population. Incidence is even higher when human skulls are examined post mortem, indicating that in some cases the exostosis is small and cannot be seen under the soft tissue. Removal of an ...
Hemimegalencephaly (HME) is a rare disorder of cortical development with overgrowth of one cerebral hemisphere. Patients have intellectual delay, hemiparesis and severe epilepsy. Drug-resistant epilepsy is often treated with a hemispherectomy. We review the literature on HME natural history and report a 26-year-old man with HME who did not undergo hemispherectomy in childhood with recurrent foc...
INTRODUCTION AND OBJECTIVE Total laryngectomy leads to pulmonary problems such as excessive sputum production, forced expectoration and increased coughing. The use of a heat and moisture exchanger (Provox(®) HME) reduces these symptoms. The aim of this study was to quantify chronic adherence to HME use in laryngectomized patients. METHODS A prospective study of 115 patients laryngectomized at...
Over the past few decades hot melt extrusion (HME) has emerged as a powerful processing technology for the production of pharmaceutical solid dosage forms in which an active pharmaceutical ingredient (API) is dispersed into polymer matrices. It has been shown that formulations using HME can provide time-controlled, sustained and targeted drug delivery, and improved bioavailability of poorly sol...
