The prevalence of bronchiectasis decreased due to the effective use of vaccines and advances of antibiotic therapy after 1970. However, it remains an important long-term morbidity of lower respiratory tract infection in developing country. To evaluate the clinical features of bronchiectasis in a tertiary hospital, we collected 21 patients with a diagnosis of bronchiectasis in Taipei Veterans General Hospital from May, 1984 to Dec, 2001 in pediatric outpatient with the admission of age below 18 years old. The diagnosis was based on the history of recurrent cough with fetid sputum, hemoptysis, or recurrent lobar pneumonia for months at least and radiological findings of lobar infiltration, tram-track like patterns, bronchiolar dilatation or honeycomb patterns. The diagnostic examinations included chest plain radiography, bronchography and chest computed tomography (CT) scans. Respiratory tract infections were the commonest cause predisposing to bronchiectasis in our study. Tuberculosis is not rare in this study. In recent years, immunodeficiency disorders have been recognized. Most patients suffered from recurrent cough and fetid sputum for years before diagnosis was established. Hemoptysis was the second common symptom in our study. The plain chest radiograph of bronchiectasis revealed dilatation of bronchial trees with honeycomb pattern or infiltration only. In recent years, chest CT became the most accurate and being noninvasive diagnostic tool. The initial treatment was primarily medical conservative therapy. Only five patients in our cases underwent pulmonary resection due to persistent hemoptysis, recurrent bacterial pneumonia or pulmonary parenchyma destruction. Most patients still suffered from recurrent pneumonia or occasional exacerbation in the long-term follow-up. In conclusion, bronchiectasis is not uncommon in pediatric population in northern Taiwan. The history of recurrent cough with fetid sputum, hemoptysis, or recurrent pneumonia were the most important clues to early diagnosis of this disease. Early diagnosis and appropriate treatment are effective in order to prevent lung abscess, empyema and pneumothorax, bronchopleural fistula, hemoptysis or cor pulmonale.

To evaluate the usefulness of differentiation of atypical pneumonia and bacterial pneumonia in the community-acquired pneumonia guidelines of the Japanese Respiratory Society, we investigated 124 cases of three atypical pneumonias (Mycoplasma pneumonia, 62 cases; Chlamydia pneumoniae pneumonia, 46 cases; Chlamydia psittaci pneumonia, 13 cases) and 403 cases of bacterial pneumonia at our hospital over seven years. Overall, the sensitivity and specificity of the criteria in the guideline were 70.4% and 91.8%, respectively. High accordance was recognized in patients under 60 years old with atypical pneumonia. Items in the criteria that included subjective factors were considered inassessable. We found that the differentiation of pneumonias in the guideline is useful for the diagnosis of atypical pneumonia among younger patients, but it should be concise and objective. We therefore propose that the criteria would be more effective if they consisted of only 4 items: age under 60 years, no underlying disorders, presence of stubborn dry cough, and normal peripheral white blood cell count.

A prospective study was initiated to analyse the bacterial aetiology and clinical picture of mild community-acquired pneumonia in Slovenia using the previously described Pneumonia Severity Index. Radiographically confirmed cases of pneumonia in patients treated with oral antibiotics in seven study centres were included. An aetiological diagnosis was attempted using culture of blood and sputum, urinary antigen testing for Streptococcus pneumoniae and Legionella pneumophila, and antibody testing for Mycoplasma pneumoniae, Chlamydia pneumoniae, and Legionella pneumophila in paired serum samples. One hundred thirteen patients were evaluable for clinical presentation and 109 for aetiological diagnosis. At least one pathogen was detected in 62.4% patients. The most common causative agents were Mycoplasma pneumoniae in 24.8%, Chlamydia pneumoniae in 21.1%, and Streptococcus pneumoniae in 13.8% of patients. Dual infection was detected in 8.3% of patients. Most patients suffered from cough, fatigue, and fever. Patients with atypical aetiology of pneumonia differed from those with typical bacterial pneumonia or pneumonia of unknown aetiology in age, presence of dyspnea, and bronchial breathing on lung auscultation. Patients with pneumococcal, chlamydial, and mycoplasmal infections differed in age, risk class, presence of dyspnea, bronchial breathing, and proteinuria. There was an overlap of other clinical symptoms, underlying conditions, and laboratory and radiographic findings among the groups of patients classified by aetiology. Since patients with mild community-acquired pneumonia exhibit similar clinical characteristics and, moreover, since a substantial proportion of cases are attributable to atypical bacteria, broad-spectrum antibiotic treatment seems to be recommended.

Two types of pneumonia are well recognized during influenza: primary viral pneumonia and secondary bacterial pneumonia. Primary viral pneumonia occurs after a typical onset of influenza with rapid progression of dyspnea and cough leading to acute respiratory distress syndrome. Treatment consists of respiratory assistance, but mortality is high. Secondary bacterial pneumonia occurs more frequently in the elderly and in patients with chronic pulmonary diseases. Staphylococcus aureus, Streptococcus pneumoniae and Haemophilus influenzae are the most frequently isolated bacteria. After an initial phase of clinical improvement, manifestations of bacterial infection with pulmonary consolidation occur. The outcome is favorable with antibiotics but depends on the patient's underlying conditions.

We report four cases of Q fever pneumonia diagnosed using PanBio Coxilla burnetii ELISA. The patients, a 21-year-old woman, a 53-year-old man, a 74-year-old man and a 87-year-old man, were among 284 with community-acquired pneumonia who were treated as inpatients from March 2001 till March 2003. The frequency of Q fever pneumonia in community-acquired pneumonia was 1.4%. The 21-year-old woman was a typical case of Q fever pneumonia, since her clinical features showed 1. the breeding of cats, 2. development from a fever and non-productive caught in March, 3. multiple soft consolidations in the chest radiograph, 4. normal WBC count, 5. cure by administration of clarithromycin. The pneumonias of the other 3 cases were considered to be mixed infections, with bacteria such as Streptococcus pneumoniae and Haemophilus influenzae. Their clinical features were 1. elderly male patients with underlying diseases, 2. development from fever and cough with purulent sputum in winter, 3. coarse crackle on auscultation, 4. consolidation with pleural effusion in chest radiograph, 5. leukocytosis, elevation of BUN, hyponatremia, 6. a few cases with unfavorable prognoses despite medication with carbapenem and minocycline. These findings suggested that two types of pneumonia exist; one with the usual features of atypical pneumonia, and the other presenting the clinical features of bacterial pneumonia of the elderly due to a mixed infection including C. burnetti.

The aim of the study was to assess the clinical features of Q fever pneumonia in Japan. Four cases of Q fever pneumonia (a female aged 21 and males aged 53, 74 and 87 years) who were diagnosed using the PanBio ELISA test kit, were assessed and their clinical features are described. The frequency of Q fever pneumonia among our cases of community-acquired pneumonia was 1.4% (4/284). A 21-year-old female had a typical case of the disease with (i) a history of owning a cat, (ii) onset with fever and dry cough, (iii) multiple soft infiltrative shadows on CXR, (iv) a normal white blood cell count, and (v) good response to clarithromycin. The pneumonias in the other three cases were considered mixed infections with bacteria such as Streptococcus pneumoniae and Haemophilus influenzae. Their clinical features included the following: (i) an elderly person with an underlying disease, (ii) onset with fever and purulent sputum, (iii) coarse crackles on auscultation, (iv) infiltrative shadows and pleural effusion on CXR, (v) increased white blood cells with elevated BUN and hyponatraemia, and (vi) modest responses to combined therapy with carbapenem and minocycline. Our observations suggest that two types of pneumonia caused by Coxiella burnetti exist; one with the usual features of atypical pneumonia, and the other presenting with the clinical features of bacterial pneumonia in the elderly due to mixed bacterial infection.

We retrospectively reviewed 34 consecutive patients with serologically confirmed leptospirosis admitted during years 1992-2002. Nine patients (26.5%) had respiratory symptoms on admission including cough (n = 4), shortness of breath (n = 4), cyanosis (n = 2), and hemoptysis (n = 1). Six patients had pulmonary radiographic findings including (1) diffuse, ill-defined, ground-glass density (n = 3); (2) diffuse alveolar opacities (n = 2); and (3) small nodular density (n = 1). Male/female ratio was 8/1 and mean age was 47 years. Seven patients reported their exposure source including hunting (n = 2), fishing (n = 2), fresh water swimming (n = 2), and canoeing (n = 1). All patients had fever (mean = 40.1 degrees C). Other common symptoms were headache (n = 4), vomiting (n = 3), and myalgia (n = 3). Biological abnormalities included elevated liver enzymes (n = 8), proteinuria (n = 7), lymphopenia (n = 6), hematuria (n = 5), renal failure (n = 4), anemia (n = 4), and elevated neutrophil count (n = 4). PaO(2 )was measured for 3 patients while they were breathing room air (32, 55, and 66 mmHg). Suspected diagnosis on admission included leptospirosis (n = 2), bacterial pneumonia (n = 2), intoxication, influenza, viral hepatitis, biliary tract lithiasis, and rapidly progressive glomerulonephritis (one patient each). The first serologic testing for leptospirosis was positive for 5 patients (55%). Serovar was presumptively identified for 7 patients: Australis (n = 3), Grippotyphosa (n = 2), and Icterohaemorrhagiae (n = 2). Seven patients were treated with penicillin; two patients received no antibiotics. All patients were cured. In conclusion, patients with leptospirosis may present predominantly with nonspecific pulmonary symptoms. In these patients, leptospirosis must be suspected when there is a potential exposure to rats, especially in case of high-grade fever, myalgia, hepatitis, and renal abnormalities.

Leukemic pulmonary infiltration, as an initial presentation of acute leukemia, is rare and poses a therapeutic dilemma. Leukemic infiltrate of the lung may be unrecognized, as patients can present with cough, fever and localized roentgenographic infiltrate, all suggestive of bacterial pneumonia. Acute promyelocytic leukemia (APL) is a subtype of acute myeloid leukemia (AML) with distinct clinicopathologic features, such as: younger age of patients, shorter duration of symptoms before diagnosis, pulmonary infiltration with atypical promyelocytes and bleeding tendency due to disseminated intravascular coagulation (DIC). APL can become rapidly fatal if not treated early in its course. We report a case of APL with diffuse pulmonary infiltration and abnormal complete blood count. He was initially diagnosed and treated as an outpatient for community-acquired pneumonia. The patient returned with worsening pulmonary infiltrate, abnormal peripheral smear and respiratory failure, resulting in death within three months of his initial presentation. As evidenced by this case, acute leukemia should be considered in the differential diagnosis for pulmonary infiltrate and abnormal hematological findings.

This prospective study was conducted at Bamrasnaradura Hospital from November 11, 2002, until January 5, 2003, in order to describe the clinical manifestations and determine the aetiologies as well as to assess the short-term outcome of interstitial pneumonitis in HIV/AIDS patients. 59 patients with interstitial infiltrates on chest radiographs were included in the study. Tuberculosis (TB) was the most common diagnosis (44%), followed by Pneumocystis pneumonia (PCP) (25.4%), bacterial pneumonia (20.3%) and fungal pneumonia (10.2%). In TB, compared to other diagnoses, a mild cough (p = 0.031), pallor (p = 0.021), lymphadenopathy (p < 0.001), an absence of skin lesions (p = 0.003), a higher mean body temperature (p = 0.004) and an absence of dyspnoea on exertion (p = 0.042) were significant findings. In PCP, compared to other diagnoses, dyspnoea on exertion (p = 0.014), nonpurulent sputum production (p = 0.047), a higher mean respiratory rate (p < 0.001), and an absence of lymphadenopathy (p < 0.001) were significant factors. In bacterial pneumonia, compared to other diagnoses, production of purulent sputum (p = 0.014), haemoptysis (p = 0.006), skin lesions (p = 0.002) and severe cough (p = 0.040) were significantly associated factors. In fungal pneumonia, compared to other diagnoses, headache and papulonecrotic skin lesions were common findings, but no factor showed a significant association. After four weeks, 59.3% patients were alive and 13.6% had died. Among those alive, 88.6% had clinically improved. The cumulative survival after 28 days was highest among PCP patients, followed by bacterial pneumonia, TB and fungal pneumonia, but these differences were statistically not significant (p = 0.453).

Influenza is a common respiratory condition that has a history of developing into epidemics and pandemics. Individuals at risk of influenza and related complications include older people, young children and individuals with chronic renal, cardiac and respiratory diseases. Influenza can begin suddenly and is accompanied by fever, chills, aches, pains, headaches, fatigue, cough and generalized weakness that can last up to 14 days. Complications of influenza include secondary bacterial pneumonia, post-influenza encephalitis, changes in cardiac electrocardiogram and secondary bacterial infections, such as Staphylococcus aureus-induced myositis. The influenza vaccine is the main form of treatment. Suitably qualified nurse prescribers and nurses who supply and administer the vaccine under patient group directions should be sufficiently knowledgeable about the virus and how its transmission can be prevented in order to educate patients at risk of developing influenza about the role of the vaccine in the prevention of the disease.
