Eighty-two patients were hospitalized following an accidental exposure to chlorine. All patients presented with dyspnoea and cough. The other symptoms included irritation of throat (53.6%), irritation of eyes (42.3%), headache (29.2%), abdominal pain (26.8%), vomiting (24.3%) and giddiness (9.7%). All of them had bronchospasm and 5 (6%) had cyanosis at the onset. An x-ray of the chest revealed patchy infiltrates in 3 (3.85%) and hilar congestion in 2 (2.44%). Pulmonary function tests showed an obstructive pattern in 27.4%, restrictive in 3.25% and mixed in 53.2%. Pulmonary functions were normal in 16.1% of the patients. Bronchoscopy revealed tracheobronchial mucosal congestion in all cases, hemorrhagic spots in 35.7%, erosions and ulcers in 12.5%. All patients were treated with oxygen, aminophylline, hydrocortisone and antibiotics. Haematemesis (n = 1) and pulmonary oedema (n = 2) developed 12 hours after the admission. Two other patients developed pneumonia 48 hours later. All patients recovered satisfactorily. On follow-up 16 patients had no sequelae after one year. Pulmonary functions were normal in 5 patients after 3 years of follow-up.

A 57-year-old man had suffered from poorly controlled diabetes mellitus and liver cirrhosis due to alcohol and hepatitis C for about 10 years. He developed fever and swelling of the right cheek and neck due to periodontal infection. The symptoms worsened in spite of antibiotic therapy and were accompanied by dyspnea. He was therefore referred to our hospital. Chest radiographs and computed tomographs revealed widening of the superior mediastinum, pulmonary infiltrates and right pleural effusion. He was diagnosed as having mediastinitis, right pyothorax and pneumonia caused by periodontal infection. Tracheotomy and mechanical ventilation were performed. Antibiotic therapy resulted in improvement of the mediastinitis and pyothorax. However, renal and liver dysfunction developed and the patient died of multiorgan failure after 35 days of hospitalization. Death due to periodontal infection is rare. We give a review of the literature.

Clinical and therapeutic features of 13 adult patients, diagnosed of Pneumonia Varicellosa are retrospectively reviewed, for the last ten years period, at Valle de Hebron General Hospital, Barcelona. Most of them had a cigarette consumption of over 20 per day, three of them showed simple chronic bronchitis criteria, and two had antibodies against HIV. Respiratory symptomatology, and dry cough, was present in 9 (75%), dyspnea in 7 (53%) and pleuritic pain in 6 (46%). Thorax radiology showed a bilateral interstitial pattern. IV aciclovir treatment was begun in patients with respiratory symptoms and hypoxemia (53%) with good therapeutic response.

The clinical features, microbiology, treatment, and outcome in 24 children diagnosed with lung abscess at Harare Central Hospital during 1979-88 were reviewed retrospectively. This condition is rare in children, and the present study is the first to address lung abscess in Zimbabweans. 17 (71%) of the 24 patients were male and their mean age was 4.9 years. The most common presenting symptoms were fever, cough, and breathlessness. Abnormal chest signs (e.g., localized dull percussion note, with amphoric or bronchial breathing) were detected in 18 cases. Foremost among the predisposing factors were measles (25%), empyema thoraxis (17%), and unconsciousness (13%). Bacteria were isolated from 18 children, with Staphylococcus aureus (8 cases), group A beta hemolytic streptococci (4 cases), and Pseudomonas aeruginosa (3 cases) the most common. Treatment consisted of bronchoscopy to aspirate pus from the bronchus and exclude foreign bodies as well as antibiotic administration. There were 6 deaths (25% case fatality rate). The prevention or prompt treatment of measles is urged to reduce further the incidence of this rare health condition. However, the spread of human immunodeficiency virus infection among children in sub-Saharan Africa is likely to be accompanied by pediatric lung abscess cases secondary to pneumonia.

The article describes one case of exogenic allergic alveolitis (EAA) developed in female engaged into shoe-making during 20 years and exposed to high concentrations of industrial multicomponent aerosols. Having pneumonia-like exacerbations, the disease demonstrated growing dyspnea and intercurrent pulmonary infiltrations. Such diagnoses as pneumonia, pulmonary tuberculosis, Loeffler syndrome, pulmonary sarcoidosis and EAA were discussed. The diagnosis of "shoe-maker's" EAA was based on the features of anamnesis, occupational life and manifestations confirmed by immunologic and morphologic data. Endobronchial lavage with hydrocortisone administration was proved to be effective. The importance of clinical and immunologic criteria, examination of ability to work in people suffering from EAA was stressed.

We report on a case of spontaneous torsion of the right lung in a 59 years old woman which occurred after an acute pneumonia followed by chronic empyema and progressive dyspnea with marked respiratory disability. Despite extensive diagnostic procedures including bronchoscopy and bronchography the true diagnosis could be established only by thoracotomy performed in order to cure the chronic empyema. The abnormal hilar rigidity by preexisting calcified sarcoidosis of the lymph-nodes is suggested to be a major risk factor for developing lung torsion as it has been emphasized in a few similar reports from the literature. Surgical reposition of the displaced lung is the most effective treatment and can save and restitute lung structure and function even in patients with prolonged course and delayed diagnosis.

A neonatal case of legionnaires' disease (LD) is reported. A male neonate was admitted to our hospital with high fever and dyspnea, which had started 5 days after birth, and died due to severe pneumonia at 10 days old. An autopsy revealed small areas of granular consolidation scattered diffusely in the bilateral lungs. Microscopic examination of the lungs showed mainly lobularly distributed pneumonia. Extensive exudation of macrophages and neutrophils was observed in the terminal respiratory tract and alveolar spaces. Warthin-Starry and Gimenez staining and electron microscopy detected many coccobacilli in the cytoplasm of exudated macrophages and neutrophils. Immunofluorescence staining using antiserum against Legionella pneumophila, serogroup 1, showed a positive reaction. Bacteriological examinations of aspirate from the respiratory tract and autopsied lung tissue confirmed the presence of Legionella pneumophila, serogroup 1. Extrapulmonary LD was not detected. LD usually affects aged or immunocompromised hosts, but there was no evidence of immune deficiency in this case. Pediatric cases of LD have rarely been reported, and a survey of the literature revealed few neonatal cases. The present case may alert neonatologists and other medical personnel to the possibility of neonatal LD infection.

Physicians analyzed December 1982-November 1989 data on 48 2-60 month old children with empyema thoracis at the University of Calabar Teaching Hospital in southeastern Nigeria to determine the incidence and etiology of empyema thoracis in this region. The incidence rate stood at 2/1000 pediatric admissions. 3 children died (6.3%), all of heart failure. 47 children suffered from fever, cough, and breathlessness, the symptoms for pneumonia. Even though bronchopneumonia is a common complication of measles which occurs frequently in Calabar, only 3 children (6.25%) also had measles. The most frequent complication of this accumulation of pus in the thoracic cavity was congestive heart failure (16 cases). 47 patients suffered from anemia (hemoglobin levels 11 gm/dl). Hemoglobin levels of 54% of all patients decreased over time to 8 gm/dl. In fact, 2 children had hemoglobin levels of 4.4 gm/dl and they experienced cardiac failure. Laboratory personnel were only able to examine pleural aspirates from 37 patients. They did not detect any organisms in 27% of these aspirates. This may have been due to parent's widespread practice of giving medication to all the children before coming to the hospital. 45.9% of the aspirates only grew Staphylococcus aureus while another 8.1% grew it and other pathogens. About 90% of the pathogens were resistant to ampicillin and penicillin and almost 90% were sensitive to cloxacillin, gentamicin, and erythromycin. Cloxacillin was very expensive and parenteral erythromycin was unavailable. Nevertheless the pediatricians used parenteral gentamicin and cloxacillin. The parents were responsible for buying the antibiotics which tended to be costly. All the patients required emergency closed tube thoracostomy drainage within 24 hours of admission. 83.3% remained in the hospital for 2 weeks and 33.3% for 1 month. Despite the rarity of empyema, long hospitalization and expensive drugs make it an important disease in Calabar.

The aim of this study was to evaluate whether the amount of Pneumocystis carinii organisms found at fiberoptic bronchoscopy (FB) performed on HIV-positive patients correlated to the character of the P. carinii pneumonia (PCP). A consecutive series of 105 patients presented with 131 episodes of pulmonary symptoms requiring FB, and in 75 of these episodes a diagnosis of PCP was made. Specimens were stained with Giemsa and methenamine silver nitrate and the number of parasites found was given as: numerous, many, few or none. The following signs and symptoms were registered: cough, dyspnoea, fever, loss of weight, chest radiograph, haemoglobin, WBC, CD4 cell count, PO2 and HIV p24 antigen. The PCP was characterized by the clinical course: mild, moderate, severe, and by the outcome: pulmonary healthy, pulmonary insufficiency and death. No correlations between the number of P. carinii organisms and the clinical course or outcome of the PCP, the symptoms before the FB or the paraclinical examinations were found. In conclusion, the routinely obtained quantitative results of the microbiological examinations of material from the lungs were not correlated to the severity of the PCP.

It has been previously demonstrated that serum lactate dehydrogenase is elevated among HIV patients with pneumocystis carinii pneumonia (PCP). To evaluate the clinical utility of this test we analyzed the admission LDH levels of patients hospitalized for the first time due to the secondary complications of AIDS. Among 76 patients without a prior history of PCP, 41 (54%) had PCP diagnosed during their hospitalization while 35 (46%) did not have PCP. Serum LDH was significantly higher among PCP patients than in patients without PCP (mean = 423 IU/L vs 234 IU/L). Receiver operating characteristic curve analysis demonstrated that at an optimal cutoff point of LDH greater than or equal to 240 IU/L, the test sensitivity and specificity were 0.78 and 0.74 respectively among all hospitalized patients. However, when only patients with dyspnea were considered, the optimal test sensitivity and specificity improved to 0.94 and 0.78 at a cutoff point of LDH greater than or equal to 220 IU/L. Comparing the areas under fitted ROC curves, serum LDH was a significantly better discriminator among patients with dyspnea than among those who were not short of breath. We conclude that while serum LDH is strongly associated with the presence of PCP among AIDS patients, it is a poor screening test for PCP when applied to all hospitalized AIDS patients with and without respiratory complaints. Serum LDH is no substitute for appropriate microbiological studies. However, with further evaluation, it may prove to be a useful test in guiding the clinical management of dyspneic patients in whom sputum or bronchial examinations are negative or not immediately available.
