Passive smoking is the problem all of us but the most harmful is for health of the children. The work aims was the assessment of frequency of occurrence of disease symptoms in the respiratory system in children up to 7 years of age depending on exposure to passive smoking. 100 children admitted to the Regional Children's Hospital in Bydgoszcz were subject to research; all of them living in the Kujawsko-Pomorskie Voivodeship. Research was conducted from May until December 2003. Information concerning family and social situation of the group examined was gathered; also data on disease history and environment was taken. The most frequently occurring respiratory system diseases were: rhinitis--in 69 (69%) children, pharyngitis--in 59 (59%) patients, bronchitis--58 (58%) children, laryngitis--30 % cases, and pneumonia was observed in 23 (23%) children examined. The lowest number--only 3 (3%) persons had sinusitis. The effort was also taken to determine the relation between the frequency of occurrence of symptoms and chronic diseases in the respiratory system and exposure to passive smoking. Research showed that the frequency of occurrence of bronchitis and hoarseness remains in significant statistical relation with passive smoking.

Respiratory tract infections are frequent and they are one of the commonest causes of antibiotic prescription. However, there are few clinical guidelines that consider this group of infections. This document has been written by the Andalusian Infectious Diseases Society and the Andalusian Family and Community Medicine Society. The primary objective has been to define the recommendations for the diagnosis and antibiotic treatment of respiratory tract infections apart from pneumonia. The clinical syndromes evaluated have been: a) pharyngitis; b) sinusitis; c) acute otitis media and otitis externa; d) acute bronchitis, laryngitis, epiglottitis; e) acute exacerbation of chronic bronchitis; and f) respiratory infectious in patients with bronchiectasis. This document has focused on immunocompetent patients.

The aim of this study is to assess the impact of some selected bacteriological factors on the occurrence of subglottic laryngitis in children. The research covered 72 children hospitalized in the Children's Hospital in Warsaw with the following symptoms: dry barking cough, stridor, inspiratory dyspnoea with the participation of auxiliary respiratory muscles, agitation and change of colour of skin. Subglottic laryngitis is one of the acute children's diseases, directly caused by a violently growing odema of the subglottic area. The disease constitutes 5-8% of all severe airways inflammations and states that subglottic laryngitis is responsible for 6.5% off all lower airways inflammation cases. Based on preliminary examinations, the patients were divided into two groups--one of them composed of 41 patients with simultaneous atopy, the other--of 31 patients with no atopy symptoms. The examination of each patient included subjective, objective (pediatric and laryngological) and auxiliary (primary-blood cell count, OB and specialized-bacteriological tests) examinations. Own research showed that out of 72 patients with subglottic laryngitis 56.95% had bacterial symptoms. 90.32% in non atopic group have higher NBT test, in atopic children it was 39.02%. We observed that 50.51% of the patients suffering from subglottic laryngitis had an inflammation of upper airways (otitis media, rhinitis, pharyngitis) and 13.89% of lower respiratory tract (bronchitis, pneumonitis). Many authors incline to say that bacteria may be a conductive factor for subglottic laryngitis to develop. However, many factors seem to suggest that the occurrence and symptoms of subglottic laryngitis are primarily caused by the reaction to an infection. The impact of bacteria onto the etiopathogenesis of subglottic laryngitis has been discussed for many years. Some experts are of the opinion that the disease develops on the bacteriologic background.

The objective of the study was to evaluate the possible association between maternal acute respiratory infectious diseases (ARID) during pregnancy and birth outcomes. Newborn infants born to mothers with or without ARID as reference were compared in the population-based large data set of newborns without any defect in the Hungarian Case-Control Surveillance System of Congenital Abnormalities. Main outcome measures were birth weight and gestational age at delivery, in addition the rate of preterm births and low birthweight newborns. Of 38,151 newborns, 3,455 (9.1%) had mothers with ARID during pregnancy which were differentiated according to six manifestations from sinusitis to the pneumonia. Mothers with ARID in pregnancy had a longer (0.3 week) gestational age at delivery (adjusted t = 5.4; p < 0.0001) and a lower rate of preterm births (6.7% vs. 9.4%) [adjusted odds ratio (OR) with 95% confidence interval (CI): 0.72, 0.63-0.83] than mothers without ARID. However, severe ARID (bronchitis-bronchiolitis and particularly pneumonia) associated with a higher rate of preterm births (13.0%, adjusted OR with 95% CI: 1.4, 1.1-1.8), while mild ARID (sinusitis, pharyngitis, tonsillitis, laryngitis-tracheitis) resulted in a lower rate of preterm births (5.5%, adjusted OR with 95% CI: 0.5, 0.4-0.7). In conclusion, there was an obvious correlation between severity of ARID in pregnant women and rate of preterm births.

A novel member of the parainfluenza virus family was identified in a bottlenose dolphin with respiratory disease. The case animal was a 19-year old male Atlantic bottlenose dolphin (Tursiops truncatus) that presented with signs of respiratory illness, including raspy, foul-odored breaths and cream-colored exudate from the blowhole. Focally extensive pyogranulomatous bronchointerstitial pneumonia with moderate numbers of intralesional yeast organisms was identified on histopathological examination. Other significant microscopic findings included multifocal erosive and ulcerative tracheitis and laryngitis consisting of active laryngeal lymphatic tissue and dilated glands with eosinophilic fluid. The cause of death was attributed to respiratory disease of unknown etiology. In addition to the postmortem isolation of Candida glabrata and mixed bacteria from lung tissue, a virus was isolated from two antemortem affected lung aspirates collected over a 2-month period and two postmortem samples (mediastinal lymph node and left lung tissue homogenate). The morphology of the virions on negative staining and transmission electron microscopy was consistent with that of paramyxoviruses. Two genomic fragments, comprising 532 and 419 nucleotides from the open reading frames that code for the viral polymerase and fusion protein, respectively, were amplified by polymerase chain reaction using degenerate primers. Phylogenetic analyses of the two viral RNA segments showed that the isolate comprised a novel virus strain, tentatively named T. truncatus parainfluenza virus type 1 (TtPIV-1). The virus is monophyletic with, but genetically distinct from, the various bovine parainfluenza virus type 3 strains.

Mycoplasma bovis was identified by a specific lesion, conventional bacterial culture, immunohistochemistry, and polymerase chain reaction in 2 feedlot bison found dead with severe, chronic, caseonecrotic pneumonia; polyarthritis; and laryngitis. On microscopic examination, pulmonary lesions were characterized by prominent, well-defined areas of caseous necrosis and bronchiectasis. Immunohistochemical analysis of lung exhibited staining in bronchiolar epithelium and in random areas of caseous necrosis. On gross examination, the laryngeal lesion observed in 1 animal was typical of changes seen in cases of calf diphtheria. Nasal swabs taken from 6 clinically ill bison from the same feedlot revealed 1 animal shedding M. bovis by the nasal route. No other pathogens were recovered from the pulmonary or laryngeal lesions; however, Mannheimia haemolytica was cultured from the nasal swabs of 2 clinically ill bison, although not from the animal found to be shedding M. bovis. Several other affected bison had swollen joints and exhibited lameness and a reluctance to move. Changes observed in dead and clinically ill bison from this feedlot are similar to what has been described in the literature as chronic pneumonia and polyarthritis syndrome in feedlot cattle caused by M. bovis. Based on the severity of the lesions, and the number of dead and affected animals, bison in a feedlot setting appear to exhibit sensitivity to infection with M. bovis.

Neonatal respiratory tract infections, in particular pneumonia, can be life-threatening. Lower respiratory tract infections may be acquired before, during, or after birth. Upper respiratory tract infections include otitis, sinusitis, rhinitis, laryngitis, tracheitis and bronchitis. Treatment of septicaemia and respiratory infections is based on the nature of the infection.

This study was conducted to determine the seasonal distribution of human metapneumovirus (hMPV) infection in the Suzhou area of China, to discuss the epidemiological and clinical features of the disease, and to examine the genetic variation of the virus in China. From November 2005 to October 2006, a total of 1932 children with acute respiratory infections, admitted to the Children's Hospital Affiliated to Soochow University, were tested for the presence of hMPV using a reverse-transcription polymerase chain reaction. Of the 1932 collected samples, 128 (6.6%) tested positive for hMPV. Most hMPV-positive cases occurred during November 2005 to March 2006, with sporadic activity through the whole season. The main reported clinical manifestations in the children with hMPV infection were fever, cough, rhinorrhoea, and wheezing. Clinical diagnoses included upper respiratory tract infection (1.6%), laryngitis (3.3%), bronchiolitis (41.5%), pneumonia (47.1%), and asthma exacerbation (6.5%). Sequence analysis of the hMPV N genes showed 99-100% homology with the registered sequence in GenBank. hMPV circulates in the Suzhou area of China y-round, peaking in the period of lowest temperature. Clinical characteristics and diagnoses associated with hMPV infection are similar to other respiratory viral infections. The gene sequence of hMPV in China is highly homologous to those reported in GenBank.

Chlamydophila (Chlamydia) pneumoniae is a common, non-zoonotic cause of community-acquired pneumonia (CAP) in ambulatory young adults. C. pneumoniae clinically presents as a mycoplasma-like illness frequently accompanied by laryngitis. C. pneumoniae CAP may also cause nursing home outbreaks in the elderly. Similar to Mycoplasma pneumoniae in immunocompetent hosts, C. pneumoniae CAP usually manifests as a mild/moderately severe CAP. In contrast with Legionnaire's disease, central nervous system involvement is usually not a feature of C. pneumoniae CAP. M. pneumoniae may rarely present with meningoencephalitis accompanied by high cold agglutinin titers. We present the case of a young man who presented with M. pneumoniae-like illness and was hospitalized for severe CAP that was accompanied by a pertussis-like cough and severe headache. Although his chest x-ray showed a right upper lobe infiltrate, a lumbar puncture was performed to rule out meningitis, but his cerebrospinal fluid profile was unremarkable. Titers for non-zoonotic atypical pneumonia pathogens were negative except for a highly elevated C. pneumoniae immunoglobulin-M titer (1:320). Testing for legionella and pertussis was negative. Q fever and adenoviral titers were also negative. Cold agglutinin titers were repeatedly negative. The patient was successfully treated with moxifloxacin but developed permanent asthma after C. pneumoniae CAP. This case is unusual in several aspects. First, C. pneumoniae usually presents as a mild to moderate CAP, but in this case it was severe. Second, hoarseness was absent, which would have suggested C. pneumoniae. Third, wheezing was an important clue to the diagnosis of C. pneumoniae, which is not a clinical finding with other causes of CAP. Fourth, permanent asthma may follow C. pneumoniae, as well as M. pneumoniae CAP. Fifth, severe headache mimicking M. pneumoniae meningoencephalitis may rarely accompany C. pneumoniae CAP.
