This prospective study represents our experiences in using fibreoptic bronchoscopy (FOB) in the evaluation of different thoracic lesions. Over a 20-month period, 203 patients (151 males and 52 females) (age range: 15-100 years) underwent bronchoscopies. The patients had a wide range of symptoms and/or radiographic abnormalities. The majority had cough and shortness of breath; haemoptysis was a common symptom. In all, 148 patients had neoplasms and 55 had non-neoplastic lesions. The most common malignancy was bronchogenic carcinoma (91 confirmed, 33 suspected). Other neoplasms included pulmonary metastases and mediastinal tumours. The non-neoplastic chest lesions included pulmonary tuberculosis, pulmonary hydatid cyst, lung abscess and resolving chest infection and chronic bronchitis. FOB was most useful in the diagnosis of bronchogenic carcinoma (positive diagnostic yield of 73%). It was least useful in diagnosing mediastinal tumours.

This article examines the health complaints of settled and nomadic Ngisonyoka Turkana of northwest Kenya. Samples of 152 nomadic and 124 settled men, aged 14 and over, were surveyed about their health status. The general pattern of disease reported concurs with previous studies of health among Turkana; that is, the primary complaints are respiratory tract infections and eye infections. The settled Turkana reported more severe complaints and higher rates of infectious disease than the nomads, including a significantly higher frequency of cold with cough, eye infection, and chest infection. Although the settled males as a group had slightly higher body mass index and other measures of body fat than the nomadic group, none of these indicators of body composition were predictive of health complaints. Observed differences in health patterns are possibly related to differences in dietary composition, exposure to pathogens associated with population density and environmental pollution, physical activity patterns, and psychosocial stress.

Professional and parental uncertainty regarding the natural history of cough and respiratory tract infection (R77) in pre-school children may in part be responsible for the high consultation, reconsultation, and antibiotic prescribing rates in this age group. The aim of the study was to review the evidence about the natural history of acute cough in children aged between 0 and 4 years presenting to primary care in terms of illness duration and complications. The study was a systematic review, with qualitative and quantitative data synthesis, of control and placebo arms of systematic reviews, randomised controlled trials (RCTs), and cohort studies set in primary care. Searches were done of MEDLINE (between 1966 and June 1998), EMBASE (between 1988 and September 1998), and the Cochrane Library databases, using the MeSH terms 'respiratory tract infection, 'cough, and 'bronchitis, and the textwords 'cough' 'bronchitis, and 'chest infection, limited to children aged between 0 and 4years, and English language articles. Eight RCTs and two cohort studies met the review criteria. At one week, 75% of children may have improved but 50% may be still coughing and/or have a nasal discharge. At two weeks up to 24% of children may be no better. Within two weeks of presentation, 12% of children may experience one or more complication, such as rash, painful ears, diarrhoea, vomiting, or progression to bronchitis/pneumonia. This review offers parents and clinicians more prognostic information about acute cough in pre-school children. Illness duration may be longer and complications higher than many parents and clinicians expect. This may help to set more realistic expectations of the illness and help parents to decide when and if to reconsult. This information may be useful to those designing patient information and self-help resources.

Underdiagnosis of asthma may lead to inappropriate management including undertreatment, and consequently to high morbidity and mortality. This study aimed at determining the rates of diagnosis and treatment of childhood asthma among medical practitioners. Relevant information on 45 asthmatic children was collected using pre-tested questionnaires. There were 30 (66.7%) males and 15 (33.3%) females (M:F, 2:1). Mean age, average ages for onset of symptoms and diagnosis of asthma were 9.4 years, 1.8 years and 6.6 years respectively. An average of 4 previous medical consultations were undertaken for asthma symptoms, but only 11 (24.4%) cases were labeled as asthma. Alternative diagnostic labels including allergy, bronchitis (wheezy), pneumonia (chest infection), and tuberculosis, were used in 29 (64.4%). Five (11.1%) cases were unlabelled. Alternative labeling for asthma was associated with frequent usage of non-bronchodilator medications including antihistamines, antibiotics, antituberculous drugs, cough mixtures, and herbal concoctions. Only 15 (33.3%) cases received bronchodilators, rarely prescribed regularly in the absence of asthma label. This study reveals low diagnosis and treatment rates for asthma, emphasising the need to audit the management of childhood asthma among medical practitioners, with the view of providing information.

In a study of the effects of indoor air pollution on the respiratory health of children in Newcastle, Australia, parental reports of symptoms experienced by children over the previous 12 months were compared with a prospective record of symptoms of cough and wheeze. Parents of 390 children aged 8-11 years completed a questionnaire about child and family respiratory health, which was used to assign children to one of four symptom groups: Wheeze (two or more attacks of wheezing in the last 12 months), Chest-Colds (two or more chest-colds in the last 12 months without wheezing), Cough Alone (a dry cough at night, without a cold or chest infection, that lasted for more than 2 weeks), or Control (none). A balanced sample of children (n=139) was invited to participate further by completing lung function tests, atopy testing, and keeping a daily diary of peak expiratory flow (PEF) and symptoms of cough and wheeze over a 7-week period. Valid data for the daily diary were provided by 66/85 (77.6%) of participants who commenced this stage (47.5% of the 139 invited to participate). The Wheeze group reported significantly more subsequent wheeze (median 16.8% of days) than the other three groups (median 0% of days). Parent reports of asthma-like symptoms over the previous 12 months were consistent with the subsequent experience of symptoms recorded in a daily diary.

Foreign body aspiration is a leading cause of death in children 1-3 years old, although mortality is low for children who reach the hospital. Presenting symptoms of an inhaled foreign body depends on time since aspiration. Immediately after inhalation the child starts to cough, wheeze, or have laboured breathing. If the early signs are missed, the child usually presents with fever and other signs and symptoms of chest infection. A plain chest X-ray has relatively low sensitivity and specificity for inhaled foreign body. The gold standard for diagnosis and management of this condition is rigid open tube bronchoscopy under general anaesthesia. For late presentations, time should be taken to fast the child and complete a thorough evaluation before bronchoscopy. The procedure should be performed in a well-equipped room with at least two anaesthesiologists, one with paediatric experience, in attendance. Most experienced anaesthesiologists prefer inhalational rather than intravenous induction of anaesthesia and a ventilating bronchoscope rather than intubation. Equally good results have been reported with spontaneous ventilation or positive pressure ventilation; jet ventilation is not advocated for foreign body removal in children.

In this study the records of 45 patients with sickle cell disease involved in 63 presentations of acute chest syndrome at the Princess Margaret Hospital in Nassau, the Bahamas, between 1997 and 2001 were examined. Patients were divided into three groups on the basis of age (<13 years, 13-18 years, >/=19 years) with a view to assessing clinical presentation. The incidence of symptoms, physical signs, and laboratory findings were enumerated and significant differences between age groups determined. The data were analysed using analysis of variance, t test, and chi(2) test and compared with existing knowledge on the subject. This study proposed to evaluate the clinical presentation of acute chest syndrome with emphasis on historical and physical findings, and to encourage the physician to maintain a high index of suspicion for the condition in susceptible patients. It was found that presentation varied significantly with age groups, children presenting most classically with fever and cough and adults, with chest pain. The 13-18 age group emerged as the group which presented most frequently with the typical symptoms of chest infection, thus potentially making diagnosis easier. Of note, the most frequent finding was a normal examination, while the second commonest physical finding was crepitations on auscultation of the chest.

Many textbooks describe symptoms and signs of lung cancer but refer to old series of patients. To update knowledge about lung cancer presentation, a study was carried out on 1,277 consecutive lung cancer patients, who were seen in a single Institution from January 1989 to October 2002. A set of 33 anthropometric, clinical, physical, laboratory, radiological, pathological and follow-up variables was prospectively recorded for all patients. In addition, information was obtained concerning symptoms of alarm (i.e. potential concern), times to specialist referral and the mix of symptoms at presentation. Patients were carefully followed-up and their subsequent clinical course was recorded. Casual discovery with absence of symptoms occurred more frequently towards the end of the study period and the prevalence of chest pain became less common. No other time-dependent changes were found in the presenting symptoms. Delay in specialist referral was longer when presentation was provoked by cough or by the occurrence of systemic symptoms, such as weight loss, anorexia and asthenia. Referral delay was longer towards the end of the study, perhaps related to an increase in the number of elderly patients with co-morbidities. Both alarm and prevalence symptoms were strong predictors of the clinical outcome, as found in both univariate analysis (favourable: casual discovery and chest infection; unfavourable: chest pain, dyspnoea, systemic symptoms and symptoms of local or systemic dissemination) and in multivariate analysis (favourable: chest infection). Early presentation of lung cancer is characterised by a specific symptomatic pattern. Knowledge of this pattern may help to improve the rate of early diagnosis.

Chest infections are serious complications in neuromuscular disorders. The predictive values of lung and respiratory muscle function including peak cough flow still remain unclear. We performed retrospective analysis of 46 children and adolescents (12.7+/-3.7 years) in whom lung function, respiratory muscle function and peak cough flows had been obtained. Data were related to: (1). number of chest infections and days of antibiotic treatment the year prior to the study and (2). history of severe chest infection requiring hospital admission. The number of chest infections and the number of days treated with antibiotics correlated with Inspiratory Vital Capacity IVC, peak cough flow PCF and Peak Expiratory Pressure PEP. Twenty-two patients were hospitalized at least once due to severe chest infection. IVC (0.65 vs. 1.44 l; P<0.0001) and PCF (116 vs. 211 l/min; P<0.0005) in these patients were significantly lower than in the non-hospitalized group. IVC<1.1l and PCF<160 l/min were specific and sensitive thresholds to discriminate between patients who had already suffered severe chest infections and those who had not. Therefore, spirometry and peak cough flow are reliable tests to identify patients at high risk for severe chest infections. Patients with IVC below 1.1l and/or PCF below 160 l/min should be well monitored and introduced to assisted coughing techniques.

Lower respiratory tract infection is easily suggested on clinical signs (cough and sputum) associated with fever. To discriminate between pneumonia and acute bronchitis is crucial because of the mortality associated with pneumonia and of its specific management. Chest X-ray is a key exam for the diagnosis and should be performed on the basis of validated clinical signs that are however of weak diagnostic value. Clinical as well as radiological signs cannot be reliably used to identify the causative germ. Sputum examination, the search for pneumococcal and legionella urinary antigens are of good diagnostic value. An associated COPD may lead to an acute respiratory failure. Acute exacerbation of chronic bronchitis results from various causes but infection is involved in about 50% of the cases, mostly viral and most often due to a rhinovirus. Viral infection can be associated to bacterial infection and the most frequently isolated germs are Streptococcus pneumoniae, Haemophilus influenzae, and B. catarrhalis. Severity assessment relies on the value of basal FEV1 that is often non available. Therefore Afssaps suggests using a dyspnea index to assess exacerbation severity.
