BACKGROUND: Anagrelide is an established treatment option for essential thrombocythemia (ET). Cardiovascular adverse events can occur with its use including heart failure and cardiomyopathy. CASE REPORT: A 52-year-old African American male with ET presented with chest pain, shortness of breath, and dyspnea on exertion. His ET was managed with hydroxyurea 1500 mg by mouth twice a day and anagrelide 1 mg by mouth 3 times a day. The patient was receiving anagrelide for approximately 2 years prior to presentation...

INTRODUCTION: Rapid maxillary expansion (RME) can change the form and function of the nose. The skeletal and soft tissue changes can influence the esthetics and the stability of the results obtained by the RME. OBJECTIVE: The aim of this retrospective study was to evaluate the short-term effects of RME on the skeletal and soft tissue structures of the nose, in mouth-breathing patients, using a reliable and reproducible, but simple methodology, with the aid of computed tomography...

The aim of the present study was to determine whether lung volume recruitment (LVR) acutely increases respiratory system compliance (Crs) in individuals with severe respiratory muscle weakness (RMW). Individuals with RMW resulting from neuromuscular disease or quadriplegia (n=12) and healthy controls (n=12) underwent pulmonary function testing and the measurement of Crs at baseline, immediately after, 1 h after and 2 h after a single standardised session of LVR. The LVR session involved 10 consecutive supramaximal lung inflations with a manual resuscitation bag to the highest tolerable mouth pressure or a maximum of 50 cmH2O...

Breastfeeding is the nourishment designed by nature for the newborn and the infant; however its prevalence is nowadays not optimal. The aim of this article is to review the current evidence of the benefits of breastfeeding for children and society, and to elaborate the risks associated with the replacement of lactation with baby formulas. Breastfeeding is a protective factor for several infectious, atopic, and cardiovascular diseases as well as for leukaemia, necrotising enterocolitis, celiac disease, and inflammatory bowel disease...

Multiple breath washout (MBW) and oxygen-enhanced MRI techniques use acute exposure to 100% oxygen to measure ventilation heterogeneity. Implicit is the assumption that breathing 100% oxygen does not induce changes in ventilation heterogeneity, however, this is untested. We hypothesized that ventilation heterogeneity decreases with increasing inspired oxygen concentration in healthy subjects. We performed MBW in 8 healthy subjects (4 female, 4 male, Age=43±15y) with normal pulmonary function (FEV1=98±6% predicted) using 10% Argon as a tracer gas and oxygen concentrations of 12...

Many people sometimes experience pain when they inhale breath across the cingula or when they consume, for example, cold drinks. The most important method of prevention is to ensure that the dentine does not become exposed. If the dentine is exposed, both chemical and mechanical damage to the surface of the tooth must be prevented. Optimal treatment should be minimally invasive and primarily consist of advising the patient to brush his or her teeth and/or rub the sensitive area with a toothpaste especially developed to ease the pain of hypersensitive teeth...

Wireless sensors are an emerging technology that allows to assist physicians in the monitoring of patients health status. This approach can be used for the non-invasive recording of the electrical respiratory muscle activity of the diaphragm (EMGdi). In this work, we acquired the EMGdi signal of a healthy subject performing an inspiratory load test. To this end, the EMGdi activity was captured from a single channel of electromyography using a wireless platform which was compared with the EMGdi and the inspiratory mouth pressure (Pmouth) recorded with a conventional lab equipment...

Scientific studies have demonstrated that an atypical respiratory rate (RR) is frequently one of the earliest and major indicators of physiological distress. However, it is also described in the literature as "the neglected vital parameter", mainly due to shortcomings of clinical available monitoring techniques, which require attachment of sensors to the patient's body. The current paper introduces a novel approach that uses multisensor data fusion for an enhanced RR estimation in thermal videos. It considers not only the temperature variation around nostrils and mouth, but the upward and downward movement of both shoulders...

OBJECTIVES: This review examined the efficacy of intranasal corticosteroids for improving adenotonsillar hypertrophy. METHOD: The related literature was searched using PubMed and Proquest Central databases. RESULTS: Adenotonsillar hypertrophy causes mouth breathing, nasal congestion, hyponasal speech, snoring, obstructive sleep apnoea, chronic sinusitis and recurrent otitis media. Adenoidal hypertrophy results in the obstruction of nasal passages and Eustachian tubes, and blocks the clearance of nasal mucus...

BACKGROUND: Re-titrations, an atypical approach to reverse PAP failure, was investigated retrospectively. METHODS: Application of our re-titration of PAP (REPAP) protocol in subjects with previous PAP failure assessed original technology (masks, modes, and pressures) in 273 subjects, of which 70% reported co-occurring psychiatric conditions. The REPAP protocol emphasized changes in pressure modes and settings to address expiratory pressure intolerance and residual breathing events; mask changes were facilitated...

Rajoshi Biswas, Nicola A Hanania, Ashutosh Sabharwal
BACKGROUND: The effectiveness of metered-dose inhalers (MDIs) in delivering medication to the lungs highly depends on its correct usage technique. Current guidelines state optimal technique for high lung deposition should include a slow inhalation (>5 seconds) at an inspiratory flow rate of 30 L/min and inhaler actuation at the start of inhalation. However, these recommendations were based on clinical studies using CFC (chlorofluorocarbon)-MDIs and in vitro studies of HFA (hydrofluoroalkane)-MDIs using idealized MDI techniques of uniform inhalation and actuation, disregarding the nonuniform techniques of actual patients...

In an attempt to obtain a deeper understanding of the factors which determine the characteristics of expirated bloodstain patterns, the mechanism of formation of airborne droplets was studied. Hot wire anemometry measured air velocity, 25 mm from the lips, for 31 individuals spitting, coughing and blowing. Expirated stains were produced by the same mechanisms performed by one individual with different volumes of a synthetic blood substitute in their mouth. The atomization of the liquid at the lips was captured with high-speed video, and the resulting stain patterns were captured on paper targets...

PURPOSE: The prevalence of sleep-disordered breathing (SDB) in patients with heart failure (HF) is high. Positive airway pressure (PAP) is first-choice therapy, but recent data indicates that PAP therapy may increase mortality in HF patients with reduced ejection fraction (HF-REF) and predominant central sleep apnea (CSA). This study investigated long-term effects of PAP therapy on pulmonary function, including respiratory muscle strength. All patients underwent multichannel cardiorespiratory polysomnography (PSG) and comprehensive lung function testing at baseline and follow-up (mean 588±43days)...

The potential for a simple, non-invasive measure of respiratory effort based on the pulse oximeter signal - the photoplethysmogram or 'pleth' - was investigated in a pilot study. Several parameters were developed based on a variety of manifestations of respiratory effort in the signal, including modulation changes in amplitude, baseline, frequency and pulse transit times, as well as distinct baseline signal shifts. Thirteen candidate parameters were investigated using data from healthy volunteers. Each volunteer underwent a series of controlled respiratory effort maneuvers at various set flow resistances and respiratory rates...
