Introduction: coughing is a physiological response to protect the airway, it produces aerosols that are identified by imaging reaching a speed of up to 8 meters per second. Extubation produces cough, hypertension, tachycardia, apnea and laryngospasm, there are methods to minimize its occurrence. Due to the COVID-19 pandemic, intravenous lidocaine and superior laryngeal nerve block have been used as cough reflex prophylaxis. The aim was to compare them in cough inhibition. Material and methods: patients aged 18-60 years, elective surgery with balanced general anesthesia, ASA 1-3, with intubation less than 3 hours, were selected. A total of 90 patients were randomized, 45 in each group. A total of 10 patients were eliminated because they presented hemodynamic instability at the end of surgery, and because the intravenous dose of lidocaine was not administered within the established time. Results: there was no statistically significant difference in the number of patients who presented cough in both groups (13 vs 10, p = 0.4684), of these there was a statistically significant difference in the number of decibels in favor of the block group (75.6 vs 67, p < 0.001). Conclusions: block presents less aerolization than intravenous lidocaine in extubation. [ABSTRACT FROM AUTHOR]

OBJECTIVE: To determine the respiratory symptoms in women from Paipa, Colombia, who have been exposed to wood smoke. MATERIALS AND METHODS: Observational study, single cohort with analytical phase. Women over 18 years of age exposed to wood smoke, who resided in the area of direct influence of the thermal plant, were included in the study. Data was collected from January 23 to November 22, 2019; they consisted of a consultation with two doctors belonging to the research, in which they were inquired about the research variables by applying a data collection sheet and later spirometry was performed. RESULTS: One hundred seven women exposed to wood smoke were included; all participants had respiratory symptoms. The average age was 53.14 years, 68.3% had some degree of overweight; 48.6% had dyspnea, 38.3% cough, 21.5% expectoration and on auscultation 7.5% had rhonchi, 4.7% had wheezing and 1.9% rales. CONCLUSIONS: Women in rural areas are at high risk of exposure to wood smoke and all patients presented respiratory symptoms, which is associated with these exposure factors. In addition, people who stop smoking are likely to reduce respiratory symptoms. [ABSTRACT FROM AUTHOR]

Introduction: Post-COVID-19 Syndrome has been the most coined terminology for the diagnosis of sequelae that persist for more than 3 months following SARS-CoV-2 virus infection. Objective: To determine the prevalence of post-COVID-19 diagnosis. Methodology: Descriptive, cross-sectional, retrospective, and observational study. The universe consists of all hospitalized patients of legal age who required oxygen therapy at the Centro Integral de Atención Provisional para Pacientes Moderados COVID-19 (FIGALI) during the first quarter of 2021. Demographic data, comorbidities, main persistent symptoms, and attendance to Post-COVID Clinics are described. Results: Predominantly those older than 50 years (66%), with an average stay of 10 days, most (79%) requiring low-flow oxygen therapy (moderate COVID-19), with equal distribution of sex and most respondents had a minimum of 5 months of discharge. The main comorbidities reported were hypertension (57%) and diabetes mellitus (31%). The prevalence of post-COVID-19 Diagnosis was 74% (131/177), with fatigue, cough and dyspnea being the main symptoms reported (45%, 32%, 29%) respectively. In the neuro-psychiatric aspect, anxiety was evident with 18% and depression in 14% of the patients surveyed. Conclusions: three out of four patients who required oxygen therapy persisted with at least one symptom more than 5 months after hospitalization, with fatigue being the predominant symptom. Despite the high prevalence described in this study, only one out of four patients reported having attended Post-COVID Clinics. [ABSTRACT FROM AUTHOR]

Chronic Obstructive Pulmonary Disease (COPD) is a pathological entity characterized by a series of persistent physical manifestations such as cough, fatigue, dyspnea and sputum production; symptoms that generate discomfort in the patient from the moment of diagnosis and that, being an irreversible disease due to the tissue damage it causes, progressively has a negative impact on quality of life. On the other hand, the presence of psychological symptoms such as depression, insecurity, anxiety and emotional disturbances has been reported in patients diagnosed with COPD. Likewise, patients with this diagnosis tend to develop behaviors that alter their family and work social relationships, as they tend to isolate themselves due to the symptoms, especially physical. This situation generates the need to develop a research work with the objective of recognizing the cluster of physical, psychological and social symptoms of patients diagnosed with COPD, and to identify if a palliative care approach is proposed. The study was developed through a systematic literature review in which 1,776 articles were identified, of which 41 were evaluated for the identification of the symptom cluster. The binomial dyspnea and cough, fatigue and expectoration were identified as the physical symptom cluster; depression and anxiety constitute the psychological symptom cluster, and the impact on quality of life and the perception of isolation or social exclusion.

BACKGROUND: Brick kiln workers exposed to smoke and dust have an increased risk of developing respiratory diseases. OBJECTIVE: To identify respiratory symptoms and their characteristics in brick workers of Tunja Boyacá, Colombia. MATERIALS AND METHODS: A cross-sectional descriptive study was done applying a questionnaire on respiratory symptoms, which met the reliability and validity criteria of brick kiln workers in the city of Tunja, based on inclusion and exclusion criteria previously established, in 2017. RESULTS: There were included 82 workers. There was evidence of respiratory symptoms, particularly waking up due to cough, whistling and problems with breathing. There is an important relationship between the sociodemographic variable position in the brickyard and the lack of air after exercise (p = 0.003); years of work in the brickyard with expectoration day and night in winter (p = 0.004) and the age of the brick maker with expectoration day and night in winter (p = 0.001). CONCLUSIONS: Respiratory symptoms are present in brickworkers; An important relationship is found between the respiratory symptoms referred by the population and certain sociodemographic variables [ABSTRACT FROM AUTHOR]

Introduction: pneumonia, named by Sir William Osler "the captain of the hosts of men's death", represents one of the main health problems in the world. Both the incidence and the mortality rate increase with age because in the geriatric patient there are diseases that increase the risk of pneumonia. In addition, due to their own health conditions and immune senescence, the probability of dying from this cause is very high. Objective: to study the main characteristics of pneumonia in the elderly and mainly the increased risk factors for developing it. Methods: a prospective quantitative-qualitative research was carried out in 950 patients aged 60 years or older with a diagnosis of community-acquired pneumonia admitted to the "Arnaldo Milián Castro" Hospital, in Villa Clara Province, from January 2016 to December 2018 with the aim of determining the risk factors of community-acquired pneumonia in the elderly. Results: the most frequent clinical manifestations were: fever, cough, decay, tachypnea and tachycardia, in various combinations. Smoking, chronic obstructive pulmonary disease, bronchial asthma, heart failure, diabetes mellitus and alcoholism were risk factors. Age was an independent prognostic factor associated with higher mortality, longer hospital stay and longer recovery time. Conclusions: the most frequently found risk factors were smoking, alcoholism, chronic obstructive pulmonary disease, cancer, diabetes mellitus and heart failure. [ABSTRACT FROM AUTHOR]

We present the case of a comorbid patient with Chronic Obstructive Pulmonary disease who developed a pulmonary herniation secondary to a coughing episode. He complained of severe and invalidating somatic pain in the herniation area, pain score was 4 out of 10 in the Verbal Numeric Scale (VNS) at rest, that worsened with cough to 9 out of 10. Buprenorphine and acetaminophen were initiated with only slight improvement in pain. Surgical reparation was discarded. An erector spinae plane nerve block (ESP block) was performed with improvement in the VNS to 0 out of 10 at rest and 6 out of 10 with cough. After the procedure, the patient only needed acetaminophen as analgesic for pain relief, and the improvement was maintained in time. The ESP block was described in 2016, and since then there has been growing evidence of its safety and efficacy in post-operative analgesia for breast, thoracic and abdominal surgery. The main ESP block benefits compared to similar blocks are the relative less incidence of pneumothorax, less systemic absorption of local anaesthetics and the simplicity of its performance. Although there is less evidence in chronic pain, it has been described in the treatment of post thoracotomy chronic pain with good results. This case is described because of the great clinical improvement in an uncommon and very symptomatic disease. [ABSTRACT FROM AUTHOR]

Introduction: thymic cyst is a condition that sits in the thymus gland. It can be congenital or acquired. Case report: It is presented a male patient who started about a year ago with a wet cough, accompanied by mucous expectoration. In the study performed, a mediastinal cystic lesion was detected and interpreted radiologically as a pleuropericardial cyst; he was operated and the lesion was completely resected by right thoracotomy. The anatomopathological diagnosis reported multilocular thymic cyst. The patient evolved satisfactorily and was discharged on the third post-operative day. Conclusions: cystic lesions of the anterior mediastinum are many times a finding because there are no symptoms until they reach great size. They must be treated surgically, with total resection, to avoid complications inherent to growth and compression and to arrive at a histopathological diagnosis. [ABSTRACT FROM AUTHOR]

The article discusses pharmaceutical assessment of patient with cough. It notes that cough is the most common symptom of the patient with disorders of the respiratory system. It adds that it is an expiratory maneuver explosive and brusque that tries to remove the sputum of the airway. It states that cough protects the lung from aspiration, with the different types of stimuli that can generate cough explaining the differences in the sounds and patterns of it.

Introduction: arterial hypertension is a health problem with high prevalence worldwide, considered one of the main cardiovascular risk factors, being a very frequent reason for consultation, both in primary care and in emergency services. Objective: to determine the Therapeutic effectiveness of two homeopathic remedies in the treatment of Hypertensive Urgency and the comparison of these remedies. Method: quasi-experimental study of 60 patients with Hypertensive Urgency in the Emergency Department of the José Martí Cast of the "Marta Abreu" polyclinic, between January 2018 and December 2018. Patients with characteristics from the homeopathic point of view of Lachesis and Aconitum were chosen and they were also randomly divided into each of the remedies in a study group that applied the homeopathic remedy to the (200CH); 5 sublingual drops every 10 minutes and another control with Captopril (25 mg) 1 tablet in both cases the blood pressure was taken systematically. Results: the ages of 50 to 60 years and the female sex predominated, in addition in both remedies the BP was reduced fundamentally at 45 minutes in both the study group and the control group, the adverse effect in the study groups that prevailed was burning in the tongue and cough in the control groups. Conclusions: it was evidenced that the homeopathic remedies studied are effective in the Treatment of Hypertensive Urgency, lowering blood pressure as well as Captopril with minimal undesirable effects in relation to conventional treatment.

OBJECTIVE: To evaluate the association between the respiratory symptomatic status and sleep disturbance in Peru's inhabitants over 15 years of age. MATERIAL AND METHOD: Secondary analysis of the Demographic and Family Health Survey (ENDES) 2015. A person with respiratory symptomatic status was one who reported having cough and phlegm for more than 14 days. A person with sleep disturbance was one who reported sleep disorders, fatigue and lack of concentration for more than 11 days in the last 14 days. The proposed association was evaluated using a generalized linear model. RESULTS: Data from 34,583 individuals were analyzed, evidencing a frequency of sleep disturbance and respiratory symptomatic status of 1.8% (590/33,478) and 2.8% (921/33,298), respectively. It was observed that participants with respiratory symptomatic status had sleep disturbances at a frequency of 1.54 times compared to those who did not have this characteristic, after adjusting for variables of interest. There was no significant difference in the frequency of sleep disturbances in relation to the duration of the respiratory symptomatic status (p = 0.992). CONCLUSIONS: There is enough evidence to suggest the possible relationship between the variables of interest, establishing that some or all the diseases associated with the respiratory symptomatic status are related to sleep disturbance.

The cough reflex is a protective mechanism of the airway; it avoids bronchoaspiration and its complications and, when it is altered, it can appear as a hypersensitivity syndrome; cough per se is the most common symptom for which medical consultation is sought. Chronic cough represents a public health problem with a high degree of morbidity; It represents a syndrome by itself, regardless of the underlying condition. Recent evidence suggests an abnormal and altered neurophysiologic process. Recent literature and new therapeutic mechanisms were reviewed. We are in the process of understanding the cough syndrome.

This article presents distinctive and essential features in the transformations of the Cuban health system that have allowed the eradication and reduction of the incidence rates of some communicable diseases at levels lower than 0.1 per 100 000 inhabitants. The results obtained are a consequence of the importance given to the prevention and control, as well as to the risks and potential damages, of these diseases. The structure and functioning of the hygiene and epidemiology subsystem and its interrelations with the rest of the system, based on the different models of service provision, have been permanent integration scenarios for decision making. Diseases such as poliomyelitis, malaria, diphtheria, whooping cough, rubella, mumps, post-mumps meningitis, measles, yellow fever, cholera, severe forms of tuberculosis, human rabies transmitted by canines, leishmaniasis, Chagas disease, vertical transmission of HIV, congenital syphilis and clinical forms such as neonatal tetanus and congenital rubella syndrome were eliminated. Some communicable diseases are analyzed in more detail and, in particular, the social response developed against tuberculosis, leprosy, AIDS and vector- borne diseases. However, the current health context presents challenges for the sustainability of the achievements made in the country. Assuring the maintenance of universal coverage with access of the Cuban population to health services will always be a principle of Cuban public health. [ABSTRACT FROM AUTHOR]

Pneumomediastinum is the presence of air in the mediastinal space, originated in bronchi, alveoli or esophageal rupture, which runs through the vascular tissue pods and towards the mediastinal space. Pneumomediastinum is classified as spontaneous or traumatic. Secondary pneumomediastinum is considered an unusual entity in children, with very variable incidence. It is associated with acute asthma airway infections, trauma, vomiting, intense efforts, anxiety with hyperventilation and drug use. This is a case report of a previously healthy, 4 year old female toddler with secondary pneumomediastinum, without trauma or thoracic procedures or instrumentation in child's pathophysiology associated with cough, with communityacquired pneumonia. It was confirmed by chest and neck radiographs. The pathology was of short duration and required treatment during a short time in the hospital. According to the chest CT scan performed at admission, air was observed migrating from the perivascular bronchial sheaths to the mediastinum ("Macklin effect"). [ABSTRACT FROM AUTHOR]

Introduction: Cough at the time of extubation may trigger anaesthesia-related adverse events. A technique that has been found to limit cough during this stage of the anaesthesia procedure is the use of remifentanil. Objective: To compare cough frequency and intensity at the time of extubation with two different plasma concentrations of remifentanil, 3-4 ng/ml and 2-3 ng/ml, using target controlled anaesthesia. Materials and methods: Randomised controlled clinical trial carried out at the Institute for Blind and Deaf Children in Valle del Cauca, in patients taken to elective ear surgery. Patients were randomly assigned to one of two groups. The first group (T) received an infusion of remifentanil at a plasma concentration of 3-4 ng/ml (n = 50). The second group (U) received an infusion of remifentanil at a plasma concentration of 2-3 ng/ml (n = 51). Data were analysed using the Student t test and the non-parametric Mann Whitney U test; the Chi square test was used for determining associations. Results: Cough intensity and frequency were less in group T compared to group U (OR: 3.73; 95% CI: 1.3-10.7), and there was no difference between the two groups regarding emergence from anaesthesia. Conclusions: The presence of at least one cough episode during extubation is less with plasma concentrations of remifentanil of 3-4 ng/ml than 2-3 ng/ml. [ABSTRACT FROM AUTHOR]

The objective of this study was to estimate the prevalence of symptomatic respiratory (SR) cases in the Peruvian population aged 15 years and over between 2013 and 2015. A secondary analysis of the Demographic and Family Health Survey (ENDES) was carried out. The subjects of the study were people aged 15 years and over who answered these interview questions: Do you currently have a cough with phlegm? How long have you had a cough with phlegm? People who had had a cough and phlegm for 15 days or more were defined as having SR. The prevalence of SR was 3.3% in 2013 (95% confidence interval [95% CI]: 2.8-3.9%), 3.8% in 2014 (95% CI: 3.5-4.1%), and 3.3% in 2015 (95% CI: 3.0-3.6%). The prevalence of SR was greater than 5% in people aged 60 years and over, in people in the poorest quintile, and in residents of rural areas. We conclude that 3-4% of Peruvian people aged 15 years and over report cough with phlegm for =15 days. The proportion with SR varies according to the region of the country. It is recommended that the expected number of symptomatic SR cases be assessed and that Peruvian healthcare be adjusted as necessary. [ABSTRACT FROM AUTHOR]

It describe the clinical case of a possible resistance to fenbendazole in a Jersey calf infested by Dictyocaulus viviparous described. In the municipality of Entrerrios (Antioquia, Colombia) a female Jersey breed of 6 months of age, presented serious sings of bronchopneumonia. which did not improve with the application of fenbendazole and enrofloxacin as maintenance therapy. At the necropsy, a large number of live parasites compatible with Dictyocaulus viviparus were observed, determining a verminous bronchitis. This nematode, which is routinely treated with fenbendazole in Colombian dairy farms, has been proved resistance when is trated with some benzimidazoles. This specific case shows the possible causes of the Dictyocaulus viviparus resistance in Jersey calf. [ABSTRACT FROM AUTHOR]

Results: 150 medical records of children under 5 who are aged between 0 and 60 months were included, of which 60% were men and 55.3% were from urban areas. The most common symptoms were cough (75%) and fever (70%). The most common diagnosis was pneumonia in 33% of cases and 56% of cases have the condition at discharge with outpatient treatment. Conclusion: The most common disease was pneumonia, over 50% came from the urban area. In most patients, the presented symptoms were fever and cough. [ABSTRACT FROM AUTHOR]

Background: Cough and laryngotracheal pain are caused when tracheal pain receptors are activated. The purpose of applying continuously a local anesthetic to block these nociceptive block these nociceptive receptors would be a logic attempt to reduce its incidence. Objective: The aim of this body of work (study) is to determine whether or not the flush of the endotracheal tube cuff with alkalized lidocaine reduces the postoperative cough and laryngotracheal pain. Material and methods: Two groups, of thirty four (34) patients each, were studied. Within the first group, the endotracheal tube cuff was flushed using alkalinized lidocaine; while in the second group, the endotracheal tube cuff was flushed using a saline solution. Using a time frame: starting at the 0 hour, then 1 hour, 6 hours and 12 hours after the procedure, the cough incidence and laryngotracheal pain were evaluated. Results: There was a direct association between the presence of cough, laryngotracheal pain and the use of a saline solution, which demonstrated a protective effect when using lidocaine. Conclusion: The use of alkalized lidocaine into the endotracheal tube cuff has a protective effect/result, which diminishes cough and laryngotracheal in the interim between the extubation and twelve hours after surgery in patients under general anesthesia.

Objective: To review the existent literature regarding chronic rhinosinusitis in children. Material and method: PubMed search using the keywords: chronic sinusitis, chronic rhinosinusitis, chronic cough in children, persistent cough, gastroesophageal reflux in children, cystic fibrosis, ciliary diskinesia. Articles were selected based on their relevance to this review. Results: Chronic rhinosinusitis in children and adults appear to have different etiology and therefore different diagnostic and treatment strategies. It is becoming more apparent that adult chronic rhinosinusitis has a relatively greater inflammatory component whereas childhood chronic rhinosinusitis has a relatively greater infectious component. This is secondary to immaturity of the pediatric immune system, the increased incidence of viral upper respiratory tract infections, the smaller ostia of the sinuses and adenoidal hypertrophy. Concentrations of eosinophils in adult mucosa are greater than those noted in children. There is a greater degree of collagen deposition and expansion of submucosal mucous glands in the adult sinus indicating more tissue remodeling and potentially greater irreversible scarring. Immune deficiencies, cystic fibrosis, and ciliary dyskinesia are more likely to occur in children. Conclusions: Careful history and physical examination, together with appropriate investigations, enable the clinician to make a correct diagnosis in the majority of cases of chronic rhinosinusitis. For the difficult cases the referral to a pediatric specialist in allergy, clinical immunology and respiratory diseases is warranted. [ABSTRACT FROM AUTHOR]

Introduction. Asthma is the most common chronic disease in children. It is characterised by coughing, wheezing and breathlessness. Symptoms, seasonality and triggering factors differ for each individual. Objective. To describe the clinical and spirometric characteristics of Mexican asthmatic children, as well as triggering factors, use of rescue therapy, seasonality and allergic sensitization. Method. Medical history, clinical evaluation, spirometric tests, and skin prick tests were performed in children attending an allergy outpatient clinic for the first time, with symptoms suggestive of asthma in the last year. Asthma severity was classified according to GINA 2002. Results. A total of 104 patients between 7 and 18 years old (10.1±2.79) were included. Male gender predominated with a 1.3:1 ratio. 58.7% had mild asthma; 29.8% mild to moderate asthma, and 11.5% moderate to severe asthma. Coughing, wheezing and nocturnal asthma were the predominant symptoms. Forced expiratory volume in one second (FEV1) (%) was between 80 and 117% (92.1±7) in the first group; between 80 and 105% (90±7.4) in the second group; and between 72 and 89% (79.2±4.8) in the third group. 58.2% of the patients had received bronchodilators in the last year (average 1.3 times/week). Most children (89.4%) were sensitized to at least one allergen. Conclusions. Asthma symptoms, triggering factors, as well as FEV1 vary individually according to asthma severity.

Introduction. From long time back it has been tried by several methods to mitigate the haemodynamic changes and the cough during intubation like in the tracheal extubation, being this it completes the one of but interest by the complexity that represents the drug combination to suppress to the haemodynamic changes and the cough, having the described schemes from calcium channel bloc-ker, local anesthetics to the extubation still anesthetized, with the purpose of to maintain without haemodynamic changes to the patient during the tracheal extubation. Material and methods. One hundred five patients divided in three groups of the following way: an experimental group (Group 1, n = 35) handled with 0.5 mg/kg of endotracheal lidocaine 15 minutes previous to the extubation and 0.5 mg/kg intravenous route 3-7 minutes previous to the extubation, an experimental group (Group 2, n = 34) handled with 0.5 mg/kg of endotracheal lidocaine 15 minutes previous to the extubation and 1.0 mg/kg of previous intravenous lidocaina 3-7 minutes to the extubation, and the group control (n = 36) to which minister saline solution by both routes, to simulate the placebo effect. Results. Was a suitable suppression of the cough in both experimental groups (p < 0.001), the control of the tachycardia and hypertension were mitigated following the dose (p < 0.05), and I am not observed delay in waking up in any of the groups (p = 0.364). Conclusions. We concluded that the lidocaine in low doses, combining the routes intravenous and endotracheal reduces to the cough and haemodynamic changes during the tracheal extubation.

Objective: To review and to analyze the existing literature regarding chronic cough in children. Material and methods: We searched published articles in PubMed using the key words: cough, chronic cough, chronic cough in children, persistent cough, gastroesophageal reflux in children. Results: Cough in children is common; the majority of cases reflect respiratory infections. Cough is rarely associated to a serious disorder. All children with cough persisting for more than 8 weeks should be evaluated. A careful history, physical examination, chest x-ray, and spirometry (in an able child) are recommended for all children with chronic cough. If a diagnosis is no evident (nonspecific cough), then an approach based on characterizing the cough as “wet” or “dry” is helpful. In each case, specific etiology-based treatment is recommended when possible; otherwise, a therapeutic trial is indicated with inhaled corticosteroids (ICS) for children with dry cough (for possible asthma) and antibiotics for wet cough (for possible protracted bacterial bronchitis [PPB] or sinusitis). The treatment should be reviewed within the specified time frame for normal response. If no effect is obvious, the treatment should be stopped and alternative diagnosis considered. Multiple etiologies may need to be treated concomitantly. Every effort should be made to identify the underlying cause. Data suggests potential harmful effects of medications used for symptomatic relief of acute or chronic cough in children. Conclusions: Medical history and physical examination, together with appropriate investigations allow the correct diagnosis of chronic cough. The diagnostic approach is summarized in Figures 1 and 2. Most cases can be managed with this algorithm. For the difficult, complex and rare cases referral to a Pediatric specialist in Allergy, Clinical Immunology and Respiratory Diseases is warranted.

Asthma is a chronic inflammatory disorder of the airway pathways characterized by an obstruction of airflow, which may be completely or partially reversed with or without specific therapy. Airway inflammation is the result of interactions between various cells, cellular elements and cytokines. In susceptible individuals, airway inflammation may cause recurrent or persistent broncho spasm, which causes symptoms including wheezing, breathlessness, chest tightness, and cough. Childhood asthma includes several different clinical phenotypes with different management strategies. The diagnosis of asthma in children requires a careful review of the child's current and past medical history, family history and a physical examination. Specialized testing is sometimes needed to diagnose asthma and to rule out other possible causes. [ABSTRACT FROM AUTHOR]

Asthma is a disorder defined by its clinical, physiological and pathological conditions. The predominant characteristic of the medical history are the episodes of breathing difficulty, particularly at night, and frequently accompanied by cough. Factors that influence the risk of developing asthma can be divided into those that cause the development of asthma and those that precipitate asthma exacerbations. Now asthma is considered a controllable disease with a combination of appropriate therapeutic and health education to the family and the patient with asthma. This education is geared primarily toward avoiding risk factors identified in each patient and the proper adherence to established treatment. [ABSTRACT FROM AUTHOR]

High Altitude pulmonary edema is a type of acute pulmonary edema, non cardiogenic, whose causes are unknown. The risk of catching the disease is higher among those who live at greater altitudes; specially children returning back home after spending 7 to 10 days at sea-level zones. It generally occurs between 24 and 96 hours alter the ascent. Subjects prone to the disease display a ventilation response to the reduced hypoxia. The case of a 10 year-old girl arriving to the emergency room with acute symptoms of breathing problems, hacking cough and chest pain has been reported. [ABSTRACT FROM AUTHOR]

The frequency of diagnosis of chest pain in children is one case in 1,000. The mean age of children is between 12-14 years. The muscleskeletal causes (in our experience 30% of cases) happen during muscular contraction. The pleural origin (20% of the cases) pain worsens at deep inspiration and when coughing. The bronchial inflammation is related to the pain in 20% of cases. The pain in intercostals nerves (seen in 1%) is in children with herpes zoster. Among the esophagus-gastric causes (5%) is due to esophagic reflux of gastric content. The psychogenic cause is seen in 10% of the children. Among the miscellaneous causes (5%) are included patients with sickle cell anemia crisis, chest wall tumors and inflammatory miopathies. The idiopathic causes (20%) are related to patients without clinical of disease, with normal laboratory and cabinet reports. Finally the causes related to the heart near to 20% of cases, but it could be some selection bias, because we are cardiologist. [ABSTRACT FROM AUTHOR]

It is define as the first wheeze episode in patients with 2 years or less, proceeded by sings and symptoms from a high respiratory tract infection. This is the most common low infection of the respiratory tract in the first 2 year of age, diagnostic criteria and its etiology is well defined, instead of that, the attitude in pharmacologic therapeutic takes personal experience and poor confidential information as its base.

Chronic cough is defined as persistent cough for more than eight weeks without a defined diagnosis. Irwin and other authors have identified sinusitis, asthma and gastroesophageal reflux as the most common causes of chronic cough. Objectives: To know the clinical spectrum and the most common causes of chronic cough, as well as lo perform a comparative analysis with the literature. Material and methods: A retrospective and transversal study was performed analyzing the clinical records of patients attending consultation because of chronic cough at Dr. Jose E. Gonzalez University Hospital at the Autonomous University of Nuevo Leon, and the Clínica Cuauhtemoc y Famosa, in Monterrey, Nuevo Leon, Mexico, from January, 1998, to December, 2000. The main symptoms and signs of each patient were analyzed, as well as the final diagnosis of the cough's cause and the response to treatment. In addition, a comparative analysis of the data found. In this population and those reported by Irwin et al on the main cause of this symptom. For the statistical analysis, multivarianza analysis, x2 test and Mantel Haenszel with 2x2 table were used considering a p < 0 05 as significant. Results: One hundred eight records were reviewed, but only 91 were included. The most common final diagnoses were gastroesophageal reflux in 75 patients (82%), followed by sinusitis in 34 cases (37%) and mixed causes (more than two) in 25 subjects (27%) (p = 0 016). All patients responded properly to specific treatment directed to the identified base-disease, with which symptoms were solved. Conclusions: In our population, unlike described by Irwin, the most frequent cause of chronic cough is gastroesophageal reflux, followed by sinusitis and mixed causes. [ABSTRACT FROM AUTHOR]

Cough is the common symptom of patients who seek medical attention; chronic cough being defined as persistent cough longer than three weeks without a definite diagnosis. Cough is a vagal phenomenon which can be initiated in structures with afferences of the vagus or its branches; besides, cough receptors have been described in different parts of the body, mainly tracheobronchial and digestive tract structures, which send afferents to the central nervous system to form the cough reflex. Main causes of chronic cough are retronasal discharge syndrome, gastroesophagic reflux and asthma. The diagnosis of chronic cough requires a careful history and physical examination and paraclinic tests focused on the most frequent causes. Treatment is oriented to identify and correct the disease; anticough medication should be used carefully since cough is a defense mechanism and an alarm sign. [ABSTRACT FROM AUTHOR]
