Statistical heterogeneity of a meta-analysis of four trials was low quality atorlip-5 5mg, and the pooled 117 effect was consistent with the effect reported in the one trial not included in the meta-analysis buy 5 mg atorlip-5 with mastercard. The body of evidence supporting a conclusion of equivalence of combination therapy and intranasal corticosteroid for this outcome was therefore considered precise order atorlip-5 5mg without a prescription. All five trials showed greater improvement in sneezing with combination therapy than with 117 intranasal corticosteroid monotherapy purchase 5 mg atorlip-5 mastercard. In four trials purchase atorlip-5 5mg visa, including Hampel (2010), treatment effects were statistically significant and ranged from 0. For the outcome of sneezing, the risk of bias was rated as low based on the quality of the 115, 121 trials. Statistical heterogeneity of a meta-analysis of four trials was low, and the pooled 117 effect was consistent with the effect reported in the one trial not included in the meta-analysis. The body of evidence supporting a conclusion of equivalence of combination therapy and intranasal corticosteroid for this outcome was therefore considered precise. All five trials showed greater improvement in nasal itch with combination therapy than with 117 intranasal corticosteroid monotherapy. For the outcome of nasal itch, the risk of bias was rated as low based on the quality of the 115, 121 trials. Statistical heterogeneity of a meta-analysis of four trials was low, and the pooled 117 effect was consistent with the effect reported in the one trial not included in the meta-analysis. The body of evidence supporting a conclusion of equivalence of combination therapy and intranasal corticosteroid for this outcome was therefore considered precise. Statistical heterogeneity of a meta-analysis of four trials was low, and the 117 pooled effect was consistent with the effect reported in the one trial not included in the meta- analysis. The body of evidence supporting a conclusion of equivalence of combination therapy and intranasal corticosteroid for this outcome was therefore considered precise. The pooled effect from a meta-analysis of three trials (85 percent of 117 patients reporting this outcome; Hampel [2010] excluded) was 0. Statistical 115 heterogeneity of a meta-analysis of three trials was low, and the pooled effect was consistent 117 with the effect reported in the one trial not included in the meta-analysis. The body of evidence supporting a conclusion of equivalence of combination therapy and intranasal corticosteroid for this outcome was therefore considered precise.

Total ocular symptom score at 2 weeks meta-analysis: combination intranasal corticosteroid plus nasal antihistamine versus intranasal corticosteroid 131 Table 50. Results were consistent across trials, but effects were statistically and clinically nonsignificant, that is, imprecise. The evidence was insufficient to support the use of one treatment over the other for this outcome. Trial size ranged from 101 to 893 patients randomized to treatment groups of interest. In all five trials, the nasal antihistamine was azelastine, and the intranasal corticosteroid was fluticasone propionate. Three 115 trials from the same article used a newly approved combination product comprising both 117, 121 drugs, and two trials used a separate nasal inhaler for each drug in the combination. Of two 117, 121 121 trials that reported the proportions of other races, one included approximately 15 percent Hispanic patients. Individual nasal symptoms (congestion, rhinorrhea, sneezing, and itching) and eye symptoms (itching, tearing, and redness) were rated on a scale from 0 (no symptoms) to 3 (severe symptoms). Morning and evening scores were summed to give a maximum score of 6 for each individual symptom. These results are based on trials using one of eight intranasal corticosteroids (12. As shown in these tables and noted above, several trials reported on each outcome.

The multicellular exocrine glands known as serous glands develop from simple epithelium to form a secretory surface that secretes directly into an inner cavity buy 5 mg atorlip-5 with visa. These glands line the internal cavities of the abdomen and chest and release their secretions directly into the cavities cheap 5mg atorlip-5 otc. The duct is single in a simple gland but in compound glands is divided into one or more branches (Figure 4 order atorlip-5 5mg fast delivery. In tubular glands order atorlip-5 5mg with amex, the ducts can be straight or coiled 5 mg atorlip-5 with visa, whereas tubes that form pockets are alveolar (acinar), such as the exocrine portion of the pancreas. Methods and Types of Secretion Exocrine glands can be classified by their mode of secretion and the nature of the substances released, as well as by the structure of the glands and shape of ducts (Figure 4. The secretions are enclosed in vesicles that move to the apical surface of the cell where the contents are released by exocytosis. For example, watery mucous containing the glycoprotein mucin, a lubricant that offers some pathogen protection is a merocrine secretion. Apocrine sweat glands in the axillary and genital areas release fatty secretions that local bacteria break down; this causes body odor. Both merocrine and apocrine glands continue to produce and secrete their contents with little damage caused to the cell because the nucleus and golgi regions remain intact after secretion. In contrast, the process of holocrine secretion involves the rupture and destruction of the entire gland cell. New gland cells differentiate from cells in the surrounding tissue to replace those lost by secretion. The serous gland produces watery, blood-plasma-like secretions rich in enzymes such as alpha amylase, whereas the mucous gland releases watery to viscous products rich in the glycoprotein mucin. Unlike epithelial tissue, which is composed of cells closely packed with little or no extracellular space in between, connective tissue cells are dispersed in a matrix. The matrix usually includes a large amount of extracellular material produced by the connective tissue cells that are embedded within it. Connective tissues come in a vast variety of forms, yet they typically have in common three characteristic components: cells, large amounts of amorphous ground substance, and protein fibers. The amount and structure of each component correlates with the function of the tissue, from the rigid ground substance in bones supporting the body to the inclusion of specialized cells; for example, a phagocytic cell that engulfs pathogens and also rids tissue of cellular debris. Functions of Connective Tissues Connective tissues perform many functions in the body, but most importantly, they support and connect other tissues; from the connective tissue sheath that surrounds muscle cells, to the tendons that attach muscles to bones, and to the skeleton that supports the positions of the body. Protection is another major function of connective tissue, in the form of fibrous capsules and bones that protect delicate organs and, of course, the skeletal system. Transport of fluid, nutrients, waste, and chemical messengers is ensured by specialized fluid connective tissues, such as blood and lymph. Adipose cells store surplus energy in the form of fat and contribute to the thermal insulation of the body. The first connective tissue to develop in the embryo is mesenchyme, the stem cell line from which all connective tissues are later derived. Clusters of mesenchymal cells are scattered throughout adult tissue and supply the cells needed for replacement and repair after a connective tissue injury. A second type of embryonic connective tissue forms in the umbilical cord, called mucous connective tissue or Wharton’s jelly. This tissue is no longer present after birth, leaving only scattered mesenchymal cells throughout the body. Classification of Connective Tissues The three broad categories of connective tissue are classified according to the characteristics of their ground substance and the types of fibers found within the matrix (Table 4. Dense connective tissue is reinforced by bundles of fibers that provide tensile strength, elasticity, and protection. Supportive connective tissue—bone and cartilage—provide structure and strength to the body and protect soft tissues. In fluid connective tissue, in other words, lymph and blood, various specialized cells circulate in a watery fluid containing salts, nutrients, and dissolved proteins. Connective Tissue Examples Connective tissue proper Supportive connective tissue Fluid connective tissue Loose connective tissue Cartilage Areolar Hyaline Adipose Fibrocartilage Blood Reticular Elastic Dense connective tissue Bones Regular elastic Compact bone Lymph Irregular elastic Cancellous bone Table 4. Fibrocytes, adipocytes, and mesenchymal cells are fixed cells, which means they remain within the connective tissue. Macrophages, mast cells, lymphocytes, plasma cells, and phagocytic cells are found in connective tissue proper but are actually part of the immune system protecting the body.

The epiglottis order atorlip-5 5mg free shipping, attached to the thyroid cartilage 5mg atorlip-5 overnight delivery, is a very flexible piece of elastic cartilage that covers the opening of the trachea (see Figure 22 order 5mg atorlip-5 with mastercard. The glottis is composed of the vestibular folds generic atorlip-5 5 mg on line, the true vocal cords 5 mg atorlip-5 sale, and the space between these folds (Figure 22. A true vocal cord is one of the white, membranous folds attached by muscle to the thyroid and arytenoid cartilages of the larynx on their outer edges. The size of the membranous folds of the true vocal cords differs between individuals, producing voices with different pitch ranges. The act of swallowing causes the pharynx and larynx to lift upward, allowing the pharynx to expand and the epiglottis of the larynx to swing downward, closing the opening to the trachea. These movements produce a larger area for food to pass through, while preventing food and beverages from entering the trachea. Continuous with the laryngopharynx, the superior portion of the larynx is lined with stratified squamous epithelium, transitioning into pseudostratified ciliated columnar epithelium that contains goblet cells. Similar to the nasal cavity and nasopharynx, this specialized epithelium produces mucus to trap debris and pathogens as they enter the trachea. The cilia beat the mucus upward towards the laryngopharynx, where it can be swallowed down the esophagus. The trachea is formed by 16 to 20 stacked, C-shaped pieces of hyaline cartilage that are connected by dense connective tissue. The trachealis muscle and elastic connective tissue together form the fibroelastic membrane, a flexible membrane that closes the posterior surface of the trachea, connecting the C-shaped cartilages. The fibroelastic membrane allows the trachea to stretch and expand slightly during inhalation and exhalation, whereas the rings of cartilage provide structural support and prevent the trachea from collapsing. In addition, the trachealis muscle can be contracted to force air through the trachea during exhalation. The trachea is lined with pseudostratified ciliated columnar epithelium, which is continuous with the larynx. These bronchi are also lined by pseudostratified ciliated columnar epithelium containing mucus-producing goblet cells (Figure 22. The carina is a raised structure that contains specialized nervous tissue that induces violent coughing if a foreign body, such as food, is present. Rings of cartilage, similar to those of the trachea, support the structure of the bronchi and prevent their collapse. The primary bronchi enter the lungs at the hilum, a concave region where blood vessels, lymphatic vessels, and nerves also enter the lungs. A bronchial tree (or respiratory tree) is the collective term used for these multiple-branched bronchi. The main function of the bronchi, like other conducting zone structures, is to provide a passageway for air to move into and out of each lung. Bronchioles, which are about 1 mm in diameter, further branch until they become the tiny terminal bronchioles, which lead to the structures of gas exchange. This muscular wall can change the size of the tubing to increase or decrease airflow through the tube. Respiratory Zone In contrast to the conducting zone, the respiratory zone includes structures that are directly involved in gas exchange. The respiratory zone begins where the terminal bronchioles join a respiratory bronchiole, the smallest type of bronchiole (Figure 22. Alveoli An alveolar duct is a tube composed of smooth muscle and connective tissue, which opens into a cluster of alveoli. An alveolus is approximately 200 μm in diameter with elastic walls that allow the alveolus to stretch during air intake, which greatly increases the surface area available for gas exchange. Alveoli are connected to their neighbors by alveolar pores, which help maintain equal air pressure throughout the alveoli and lung (Figure 22. A type I alveolar cell is a squamous epithelial cell of the alveoli, which constitute up to 97 percent of the alveolar surface area. Roaming around the alveolar wall is the alveolar macrophage, a phagocytic cell of the immune system that removes debris and pathogens that have reached the alveoli. The simple squamous epithelium formed by type I alveolar cells is attached to a thin, elastic basement membrane. Taken together, the alveoli and capillary membranes form a respiratory membrane that is approximately 0. Asthma is a chronic disease characterized by inflammation and edema of the airway, and bronchospasms (that is, constriction of the bronchioles), which can inhibit air from entering the lungs. In addition, excessive mucus secretion can occur, which further contributes to airway occlusion (Figure 22.

The body of evidence was therefore imprecise discount 5mg atorlip-5 free shipping, and evidence to support the use of one treatment over the other for these outcomes is insufficient cheap atorlip-5 5mg otc. Both 124 atorlip-5 5 mg without prescription, 125 trials were rated poor quality due to lack of blinding and lack of maintenance of 125 comparable groups atorlip-5 5 mg online. Both reported statistically significant results favoring intranasal corticosteroid order atorlip-5 5mg fast delivery. One small 128 trial included 29 patients, and the others included 285 to 736 patients. The oral leukotriene 126-129 receptor antagonist, montelukast, was compared to fluticasone propionate in four trials and 97 to beclomethasone in one trial. In two trials that reported on 97, 126, 129 race, most patients were white (approximately 78 percent). Baseline symptom scores for the 128 97, 127 trials represented a range of severity, with patients reporting mild, moderate, and 126, 129 127 severe baseline symptoms. One trial included asthma outcomes and considered prior asthma treatment as a baseline characteristic in the analysis model. To calculate the mean change from baseline, most trials 128 subtracted baseline scores from scores averaged over the entire treatment duration. One trial averaged data for intervals (weeks 1 and 2, weeks 3 to 5, weeks 6 to 8) and compared the mean change during each interval to baseline. Morning and evening peak expiratory flow were self- measured (average of three readings) with flow meters provided to patients. Albuterol use and number of nighttime awakenings due to asthma were recorded in diaries. Individual nasal symptoms (congestion, rhinorrhea, sneezing, and nasal itch) at 2 weeks: High strength evidence for equivalence of intranasal corticosteroid and oral leukotriene receptor antagonist based on three trials 126, 127, 129 with low risk of bias and consistent, precise results. These results are based on trials using two of eight intranasal corticosteroids (25 percent) in comparison with montelukast (100 percent). As shown in Table 37, variance estimates of treatment effects were provided for nasal outcomes at 2 weeks. Nasal Symptoms 126, 127, 129 Three of five trials (2014 of 2328 patients, 87 percent) assessed individual nasal symptoms (congestion, rhinorrhea, sneezing, and nasal itch) at 2 weeks. For each symptom, the treatment effect favored intranasal corticosteroid over oral leukotriene receptor antagonist and was statistically significant. Meta-analyses of the three trials for each symptom favored intranasal corticosteroid with statistically significant treatment effects ranging from 7. Treatment effects consistently favored intranasal corticosteroid in all three trials. The body of evidence to support a conclusion of equivalence of intranasal corticosteroid and oral leukotriene receptor antagonist for each of these outcomes is therefore precise. Three good quality trials of 2014 patients represented 87 percent of patients reporting this outcome. Thirteen percent of 97, 128 patients were in two trials that were rated poor quality due to inappropriate analysis of results (not intention to treat). Treatment effects favored intranasal corticosteroid over oral 128 leukotriene receptor antagonist and were statistically significant in all but one trial. Of two poor quality trials reporting on this outcome 128 using an interval rating scale, one (n=29) reported a statistically nonsignificant effect of 0. The fifth trial was excluded due to lack of a variance estimate for the treatment effect. The meta-analysis yielded a statistically significant pooled effect (standardized mean difference) of 0. Treatment effects consistently favored intranasal corticosteroid for all patients reporting this outcome. The one trial excluded from the meta-analysis did not alter the precision assessment because this trial represented 1 percent of patients reporting this outcome. The body of evidence supporting a conclusion of equivalence of intranasal corticosteroid and leukotriene receptor antagonist for this outcome is therefore considered precise. All comparisons favored intranasal corticosteroid and were statistically significant. The risk of bias for this outcome was rated as low based on the good quality of the trial reporting.
