A 58-year-old woman presented with chronic cough felt to be multifactorial secondary to asthma, gastroesophageal reflux disease, and chronic sinusitis. Additional medical history included obstructive sleep apnea, type 2 diabetes, and hypertension. She had a 40- year history of tobacco use, but quit 10 years ago. Her examination was significant for obesity and cobble stoning of the oropharynx. Pulmonary function testing and arterial blood gases were unrevealing. Chest films were normal. High-resolution computed tomography revealed multiple focal lucencies in a mosaic pattern consistent with air trapping and small airways disease. Bronchoscopy revealed normal airways and a noninflammatory bronchoalveolar lavage. Transbronchial biopsies revealed inflammatory infiltrates of the peribronchiolar interstitium. Lung biopsy revealed pulmonary neuroendocrine cell hyperplasia with tumorlets that stained positive for neuroendocrine tissue. We present the case of a woman with chronic cough, multiple medical problems, and pulmonary neuroendocrine cell hyperplasia with tumorlets.

Clinical practice guidelines for the management of acute sinusitis in children have been published by the American Academy of Pediatrics. Of note is that in this document, a brief discussion of chronic disease concluded that the pathogenesis and management are essentially unknown. Although there are insufficient data in the literature to develop evidence-based clinical guidelines, a careful review of the literature and clinical experience of experts who manage pediatric chronic sinusitis is presented in an effort to develop specific recommendations and to offer practical treatment options. Factors associated with chronic sinusitis should be addressed individually and include recurrent viral upper respiratory infections, allergic and nonallergic rhinitis, ciliary dyskinesia, cystic fibrosis, immunodeficiency, and anatomic abnormalities. Bacteriology includes the 3 pathogens associated with acute disease i.e., Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis but with chronic sinusitis also includes Staphylococcus aureus, anaerobic bacteria, and fungi. Medical interventions discussed include endoscopic sinus surgery, saline nasal irrigation, intranasal decongestant therapy, intranasal steroids, and oral antibiotics. Clinical ranking without regard to side effects and cost suggests that endoscopic sinus surgery and antral irrigation have the highest probability of substantial symptom improvement. Other issues discussed include identification and management of gastroesophageal reflux disease (GERD), allergy, and immune deficiency.

A variety of pulmonary and ear, nose, and throat (ENT) symptoms and disorders are considered to be extraoesophageal manifestations of gastro-oesophageal reflux disease (GORD). These extraoesophageal manifestations include asthma, chronic cough, laryngeal disorders, and various ENT symptoms. Recent studies have established that GORD underlies or contributes to chronic sinusitis, chronic otitis media, paroxysmal laryngospasm, excessive throat phlegm, and postnasal drip. Traditionally, management of extraoesophageal GORD manifestations relies on prolonged empiric therapy with high doses of proton pump inhibitors (PPI), followed by pH monitoring under PPI in refractory cases. Recent studies found no benefit of empiric long term high dose PPI therapy. The diagnostic yield of endoscopy in extraoesophageal GORD manifestations seems higher than previously appreciated while pH monitoring under PPI therapy has a low yield. Based on these new findings, a new management algorithm can be proposed that uses short term empiric PPI therapy and GORD investigations off PPI. Well designed controlled studies evaluating the proposed management algorithms and treatment approaches in this area are urgently needed.

Clinical practice guidelines for the management of acute bacterial rhinosinusitis in children were published by the American Academy of Pediatrics in 2001. Changes in the antibiotic susceptibility patterns for the common pathogens causing both acute and chronic rhinosinusitis warrant a reevaluation and update of these recommendations. In addition, there was only a very brief discussion of chronic disease in this publication, with the conclusion that the pathogenesis and management of recurrent or prolonged infection were essentially unknown. Although there are still insufficient data in the literature to develop evidence-based clinical guidelines, a careful review of recent literature and the clinical experience of experts who manage pediatric chronic sinusitis are presented in an effort to provide some specific recommendations and to offer practical treatment options. Factors associated with chronic rhinosinusitis should be addressed individually and include environmental pollution, recurrent viral upper respiratory infections, allergic and nonallergic rhinitis, ciliary dyskinesia, cystic fibrosis, immunodeficiency, gastroesophageal reflux, and anatomic abnormalities.

Although recent studies suggest that gastroesophageal reflux disease (GERD) may contribute to a variety of ear, nose and throat and pulmonary diseases, the cause-and-effect relationship for the vast majority remains far from proven. In this article, the evidence supporting a possible causal association between GERD and chronic sinusitis has been reviewed. The evidence would suggest that: (i) a higher prevalence of GERD and a different esophagopharyngeal distribution of the gastric refluxate occurs in patients with chronic sinusitis unresponsive to conventional medical and surgical therapy compared to the general population; (ii) a biologically plausible pathogenetic mechanism exists whereby GERD may result in chronic sinusitis; and (iii) clinical manifestations of chronic sinusitis respond variably to antireflux therapy. While these findings suggest that GERD may contribute to the pathogenesis of chronic sinusitis in some patients, it is apparent that the quality of the evidence supporting each of these three lines of evidence is low and therefore does not conclusively establish a cause-and-effect relationship. A number of unresolved issues regarding prevalence, pathophysiological mechanism, diagnosis and treatment exist that deserve further investigation in order to solidify the relationship between GERD and chronic sinusitis. In conclusion, given the possible relationship between GERD and chronic sinusitis, until more convincing data are available, it may be prudent to investigate for GERD as a potential cofactor or initiating factor in patients with chronic sinusitis when no other etiology exists, or in those whose symptoms are unresponsive to conventional therapies.

Gastroesophageal reflux disease (GERD) is associated with a variety of extraesophageal symptoms including asthma, chronic cough, laryngeal disorders, and various ENT symptoms. Recent studies suggest that GERD underlies or contributes to chronic sinusitis, chronic otitis media, dental erosion, and obstructive sleep apnea syndrome (OSAS). In this article, we review the prevalence, diagnosis, and treatment of extraesophageal symptoms and including Montreal definition, a new definition and classification of GERD by an International Consensus Group.

Observations about the natural history of aging in Cornelia de Lange syndrome (CdLS) are made, based on 49 patients from a multidisciplinary clinic for adolescents and adults. The mean age was 17 years. Although most patients remain small, obesity may develop. Gastroesophageal reflux persists or worsens, and there are early long-term sequelae, including Barrett esophagus in 10%; other gastrointestinal findings include risk for volvulus, rumination, and chronic constipation. Submucous cleft palate was found in 14%, most undetected before our evaluation. Chronic sinusitis was noted in 39%, often with nasal polyps. Blepharitis improves with age; cataracts and detached retina may occur. Decreased bone density is observed, with occasional fractures. One quarter have leg length discrepancy and 39% scoliosis. Most females have delayed or irregular menses but normal gynecologic exams and pap smears. Benign prostatic hypertrophy occurred in one male prior to 40 years. The phenotype is variable, but there is a distinct pattern of facial changes with aging. Premature gray hair is frequent; two patients had cutis verticis gyrata. Behavioral issues and specific psychiatric diagnoses, including self-injury, anxiety, attention-deficit disorder, autistic features, depression, and obsessive-compulsive behavior, often worsen with age. This work presents some evidence for accelerated aging in CdLS. Of 53% with mutation analysis, 55% demonstrate a detectable mutation in NIPBL or SMC1A. Although no specific genotype-phenotype correlations have been firmly established, individuals with missense mutations in NIPBL and SMC1A appear milder than those with other mutations. Based on these observations, recommendations for clinical management of adults with CdLS are made.

Risk factors of recurrent sinusitis involve upper respiratory infections, bacterial load of the adenoids, day care attendance and exposure to tobacco smoke as well as sinonasal abnormalities, including septal deviation, choanal atresia, polyps and hypoplasia of sinuses. Furthermore, several systemic disorders can facilitate the development of chronic sinusitis, such as allergic rhinitis, gastro-esophageal reflux disease (GER), cystic fibrosis, primary ciliary dyskinesia, and immunodeficiency diseases. A clinical practice guideline for the management of sinusitis is available only for the acute disease, but does not include for the management of the chronic form (i.e. chronic/recurrent sinusitis) and even less for the prevention strategies. As several studies indicate that the majority of children respond to sequential medical followed by surgical interventions, when needed, the best prevention of recurrence or chronicity is to properly treat acute sinusitis; in addition, children should be removed from larger and crowded day care whenever possible and should not be exposed to cigarette smoke. If allergic rhinitis co-exists, it can be managed with nasal steroids sprays and anti-histamines, although the long-term results are controversial. In case of chronic sinusitis, the strategy of prevention is to assess and to cure the associated conditions.

Although sinusitis is one of the most common problems encountered in clinical practice, it can be a challenge to diagnose and treat appropriately. Sinusitis refers to inflammation (infectious or noninfectious) in the paranasal sinuses. Infectious sinusitis can be bacterial or viral. This article focuses on bacterial sinusitis. Acute bacterial sinusitis usually follows a viral upper respiratory infection (URI) but can also present with severe symptoms 3 to 5 days after onset. Chronic sinusitis has less prominent symptoms and can be easily missed. When antibiotic therapy is warranted, the antibiotic should be chosen based on knowledge of antimicrobial resistance in specific geographic areas and populations. Adjunctive measures include saline irrigation, steam inhalation, nasal and systemic steroids, mucolytics, and decongestants. It is important to identify and treat predisposing factors, including viral URIs, allergic rhinitis, nasal structural abnormalities, gastroesophageal reflux disease, and immune deficiencies.

Asthma control is a key point in patient management. GINA's most recent report emphasises the need to investigate uncontrolled asthma, of which non-compliance with treatment, COPD, smoking, chronic sinusitis, gastroesophageal reflux disease and obesity are the usual causes. The aim of this work is to evaluate the role of pulmonary thromboembolism (PTE) in cases of difficult- -to-treat asthma. We reviewed the case reports of patients with severe persistent asthma followed in our Asthma Outpatients Clinic between 2004 and 2006. We selected the ones that maintained uncontrolled disease despite an optimal therapeutical approach and investigated the causes. In this group (n=254), 28 (11%) had severe persistent asthma and their mean age was 44 +/- SD18 years old. 86% were females. Of these, 57% (n=16) had uncontrolled disease: 35% (n=6) due to non-compliance with treatment; 29% (n=5) pulmonary thrombombolism (scintigraphic confirmation); 12% (n=2) severe rhinosinusitis; 6% (n=1) hypereosinophilic syndrome; 6% (n=1) persistent allergen exposure and 6% (n=1) are still being investigated. Patients with TPE (mean age 56 +/- SD9 years old; 80% females; 80% Caucasians) were diagnosed with asthma as adults (mean age 37 +/- SD14 years old). The mean time until the diagnosis of TPE was 18 +/- SD12 years. Predisposing factors for TPE were venous insufficiency (40%), hypertension (40%) and deficit of functional protein C and S (20%). All these patients received anticoagulant therapy (80% are still medicated). It should be noted that after the beginning of anticoagulants, 40% of the patients achieved control of their asthma and 40% have partially controlled disease. There were no hospital admissions for asthma exacerbations after the beginning of anticoagulation in this group. This study supports the inclusion of TPE in the group of comorbidities to consider while investigating uncontrolled asthma.
