Cystic fibrosis (CF) is a hereditary disease, characterized by chronic pulmonary disease, pancreatic insufficiency and abnormal electrolytes in the sweat. In order to evaluate the clinical manifestations and laboratory findings of Iranian children with CF during a 10-year period, 243 CF patients, with a median age of 5 months, were investigated in this study. The most common manifestations were gastrointestinal disorders and respiratory manifestations. Cough was the most common symptom, followed by malnutrition, diarrhea, respiratory distress, and vomiting. The frequency of these findings after treatment was significantly decreased in comparison with the period before diagnosis. During the mean follow-up of 40.9 months, seven cases died due to severe infections. Cystic fibrosis as a common genetic disorder should be considered in any child with recurrent gastrointestinal and respiratory manifestations, since delayed diagnosis could lead to severe complications and even death in this group of patients.

Oropharyngeal dysphagia is a major complaint among older people. Dysphagia may cause two types of complications in these patients: (a) a decrease in the efficacy of deglutition leading to malnutrition and dehydration, (b) a decrease in deglutition safety, leading to tracheobronchial aspiration which results in aspiration pneumonia and can lead to death. Clinical screening methods should be used to identify older people with oropharyngeal dysphagia and to identify those patients who are at risk of aspiration. Videofluoroscopy (VFS) is the gold standard to study the oral and pharyngeal mechanisms of dysphagia in older patients. Up to 30% of older patients with dysphagia present aspiration-half of them without cough, and 45%, oropharyngeal residue; and 55% older patients with dysphagia are at risk of malnutrition. Treatment with dietetic changes in bolus volume and viscosity, as well as rehabilitation procedures can improve deglutition and prevent nutritional and respiratory complications in older patients. Diagnosis and management of oropharyngeal dysphagia need a multidisciplinary approach.

Although noninvasive ventilation (NIV) use in severe acute exacerbation of COPD has substantially reduced the need for intubation, an important number of COPD patients still are mechanically ventilated through a tracheal tube in the ICU. Intubation is a major risk factor for lower respiratory tract colonization (LRTC) in ICU patients. Other risk factors for LRTC include colonization of the oral cavity, nasopharynx, and gastric content. Aspiration of contaminated oropharyngeal secretions is increased by supine position, underinflation of tracheal cuff, coma, and sedation. Tracheal tube biofilm formation plays an important role as a reservoir for microorganisms. Reduced cough reflex, altered mucocilliary clearance, hypersecretion and retention of mucus are frequent in COPD patients. In addition, malnutrition and corticosteroid use are common in this population resulting in altered cellular, and humoral immunity and higher risk for LRTC. Incidence of LRTC varies from 22-95% of intubated patients. Pseudomonas aeruginosa is the most frequently isolated microorganism at day 3 after intubation in COPD patients. LRTC is a major risk factor for ventilator-associated pneumonia, which is associated with increased mortality and morbidity in ICU patients. Several measures could be suggested to reduce LRTC in critically ill COPD patients. NIV use in severe acute exacerbations reduces the need for intubation. In addition, the early use of NIV averts respiratory failure after extubation and could reduce the duration of invasive mechanical ventilation. Other measures might be efficient in preventing LRTC such as semirecumbent position, avoidance of gastric distension, polyurethane-cuffed tracheal tubes, silver-coated tracheal tubes, subglottic aspiration, and continuous control of cuff pressure. Further studies should determine the impact of preventive measures aiming at preventing LRTC on outcome of COPD patients requiring intubation and mechanical ventilation in the ICU.

Community acquired pneumonia is the leading killer of children under the age of 5 years. In ER, a diagnosis of pneumonia may be made and the severity graded on basis of WHO's classification for pneumonia in children up to 5 years of age. It relies on age-specific respiratory rate, presence of lower chest indrawing and signs of severe illness. A diagnosis of pneumonia is made if a febrile child has history of cough and difficult or rapid breathing and a respiratory rate above age specific threshold; however, signs of airway obstruction should be ruled out. Severe pneumonia is diagnosed if with the above features lower chest wall retraction is present; nonetheless, all infants below 2 months and children with moderate to severe malnutrition with pneumonia are categorized as having severe pneumonia. A chest radiograph is indicated only if the diagnosis is in doubt; complications are suspected and there is severe/very severe or recurrent pneumonia. Non-severe pneumonia is treated at home with oral amoxicillin for 3-5 days. If there is no improvement in 48 h it is changed to amoxicillin-clavulanate. Azithromycin is added for atypical pneumonia. Indications for hospitalization include age <2 months, treatment failure on oral antibiotics, severe/very severe or recurrent pneumonia, shock, hypoxemia, severe malnutrition, immunocompromised state. Severe pneumonia is treated with injectable ampicillin; Cloxacillin is added if clinical/radiographic features suggest Staphylococcal infection. On review after 48 h, if improved, the child may be sent home on oral amoxicillin for 5 more days; if not, it is treated as very severe pneumonia. Very severe pneumonia is treated with injectable Ampicillin plus gentamicin. If improved after 48 h, oral amoxicillin and gentamicin are continued for 10 days. If not, respiratory support is enhanced, antibiotics are changed to intravenous ceftriaxone and amikacin and further work up is planned. Children with chronic diseases and recurrent pneumonia require specific antibiotics depending on the underlying cause.

Accidental aspiration of kerosene is a common problem among children in developing countries. This descriptive study involved the retrospective analysis of children admitted with kerosene aspiration in a tertiary care hospital in South India for a year. Kerosene aspiration contributed to 60.4% of poisoning cases. Boys aged less than three years and from a rural background formed a significant proportion. Tachypnoea, cough and crepitations were the predominant clinical findings. Male gender and malnutrition (weight for age <80%) were significantly associated with prolonged hospital stay.

The purpose of this study was to find out the current pattern and prevalence of acute lower respiratory tract infections in children at Nepal Medical College Teaching Hospital in Katmandu, Nepal. A retrospective study was done in 73 children, admitted to the Pediatric ward over a period of one year from January 2010-December 2010. This study showed, 52.0% children below two years of age had acute lower respiratory tract infections, where 68.4% had pneumonia and 31.6% had acute bronchiolitis. The prevalence of infections was 58.9% in male children. The occurrence of infections was common in January and April month. Pneumonia was detected in 37.7% children with malnutrition. The most common presenting symptoms was fever observed in 90.4%, cough in 71.2% and fast breathing in 34.2% children. The WBC count was high in 47.9% children, out of which 43.8% had pneumonia and 4.1% had bronchiolitis. Increased neutrophil count in 36.9% and increased ESR in 50.7% seen in patients only with pneumonia. Chest x-ray showed, lobar pneumonia in 45.2% children where right middle zone was most commonly involved in 42.4% patients. Six (8.2%) children were diagnosed as pulmonary tuberculosis. The average duration of hospital stay was 6 days.

Nontuberculous mycobacterial lung disease (NTMLD) in immunocompetent patients is an increasingly important epidemiologic concern. However, risk factors associated with susceptibility to NTMLD are not completely known. A prevalence of NTMLD appears to be rising, mainly in some populations such as middle-aged or elderly thin women, (a group including those with Lady Windermere syndrome) with neither remarkable history of respiratory disease nor smoking habit. Right middle lobe (RML) and lingula are often involved. Various predisposing factors and genetic defects have been described as possible causes of development of NTMLD, namely: voluntary suppression of cough, RML anatomical factors, menopause and mutations in cystic fibrosis transmembrane conductance regulator (CFTR). Malnutrition is also an important and common risk factor associated with other mycobacterial disease like tuberculosis (TB) and its probable association with NTMLD as have been pointed out for some authors. However, a real description of all nutritional aspects and eating habits of patients prior to NTMLD diagnosis is lacking. We hypothesized that malnutrition and eating disorders like anorexia nervosa could be risk factors that may promoting NTMLD. From a clinical viewpoint, if this hypothesis proves to be correct, eating habits and nutritional aspects should be taken into account in the diagnosis process of suspected NTMLD, since they are easily identifiable and treatable conditions.

Clinically obvious reasons why children with neurological impairment (NMI) may be more severely affected in case of a viral respiratory tract infection include reduced vital capacity due to muscular weakness or spastic scoliosis, disturbed clearance of respiratory excretions (weak coughing and dysphagia), inability to comply actively with physiotherapeutic interventions, recurrent micro-aspirations (gastroesophageal reflux disease, vomiting related to coughing), a history of frequent exposure to antibiotics and health care institutions, colonization with resistant pathogens, impaired immunologic defence mechanisms due to severe malnutrition and cachexia, and early clinical deterioration in case of high fever with metabolic acidosis and hypercapnia, and maybe associated seizures or febrile convulsions.Data from the literature suggests that in all children with NMI, who have to be hospitalized with severe clinical deterioration due to an airway infection, at least one specimen of nasopharyngeal secretions should be sent as soon as possible to a virologic laboratory to detect viral pathogens. Children with severe NMI and those mechanically ventilated for other reasons being hospitalized during the RSV season must be strictly protected against nosocomial RSV infection by means of standard and droplet precautions. Finally, children with severe NMI and age below 24 months of life should receive passive immunization with palivizumab following international recommendations.

Bidens biternata, belonging to the family Asteraceae, is an erect annual herb, up to 1 cm in height, and a widespread weed of cultivated areas. This plant is common, particularly in the Western Ghats regions of Kerala state in India. It is used as a leafy vegetable by the Paniya and Kattunaayika tribes of Waynadu Districts in Kerala and also to cure hepatitis, cold, cough, dysentery, etc. The multiplication and utilization of this leafy vegetable will help to overcome the nutritional deficiency problem and also to maintain the biodiversity. For effective biochemical analysis, plant extract was taken using different solvents. Various phytochemicals like reducing sugar, glycosides, flavonoids, alkaloids, tannins, steroids, terpenoids, coumarins, saponins, anthraquinones, phlobatannins and iridoids were estimated. Different nutritional factors like total carbohydrates, total proteins, total reducing sugar, different amino acids, free fatty acids, crude fibre, lipids, total moisture content, vitamins, etc. were tested by standard estimation methods. Anti-nutritional factors like phytic acid, total phenol, tannic acid, etc., were also estimated. Micronutrients and different pigments were quantified. The present studies revealed that this wild leafy plant has numerous nutritional factors with a low level of anti-nutritional factors. Therefore, this nutritive herb with diverse health-promoting compounds can be effectively utilized to overcome the nutritional deficiency problem around the globe.

Bacterial pneumonia has hitherto been considered the key cause of the high respiratory morbidity and mortality in children under five years of age (under-5s) in low-income countries, while asthma has not been stated as a significant reason. This paper explores the definitions and concepts of pneumonia and asthma/wheezing/bronchiolitis and examines whether asthma in under-5s may be confused with pneumonia. Over-diagnosing of bacterial pneumonia can be suspected from the limited association between clinical pneumonia and confirmatory test results such as chest x-ray and microbiological findings and poor treatment results using antibiotics. Moreover, children diagnosed with recurrent pneumonia in infancy were often later diagnosed with asthma. Recent studies showed a 10-15% prevalence of preschool asthma in low-income countries, although under-5s with long-term cough and difficulty breathing remain undiagnosed. New studies demonstrate that approximately 50% of acutely admitted under-5s diagnosed with pneumonia according to Integrated Management of Childhood Illnesses could be re-diagnosed with asthma or wheezing when using re-defined diagnostic criteria and treatment. It is hypothesised that untreated asthma may contribute to respiratory mortality since respiratory syncytial virus (RSV) is an important cause of respiratory death in childhood, and asthma in under-5s is often exacerbated by viral infections, including RSV. Furthermore, acute respiratory treatment failures were predominantly seen in under-5s without fever, which suggests the diagnosis of asthma/wheezing rather than bacterial pneumonia. Ultimately, underlying asthma may have contributed to malnutrition and fatal bacterial pneumonia. In conclusion, preschool asthma in low-income countries may be significantly under-diagnosed and misdiagnosed as pneumonia, and may be the cause of much morbidity and mortality.
