A 40-year-old woman who had recently undergone kidney transplantation was succesfully treated for diffuse influenza virus pneumonia. The illness was acute, with rapid onset, high fever, nonproductive cough, dyspnea, cyanosis, crepitations and rales over both lung bases, and associated arterial hypoxemia, leukopenia, and thrombocytopenia. Prophylactic use of antibiotics to prevent superimposed bacterial infection and reduction of immunosuppressive therapy to minimal dosage during the critical phase of the respiratory infection contributed to the patient's survival. An episode of graft rejection was reversed by resumption of immunosuppressive therapy at standard dosage levels.

Fibrosing alveolitis is a rare, diffuse lung disease characterized by varying combinations of two histological features: thickening of alveolar walls and the presence of large mononuclear cells in the alveolar spaces. Clinical details of 10 children with fibrosing alveolitis are reported. The main symptoms in children are tachypnoea or dyspnoea, cough, poor weight gain, and cyanosis. The condition is similar to that in adults, but it is usually a more acute illness, and if untreated, more predictably fatal. Respiratory failure, pulmonary hypertension, and cardiac failure are the major complications. Less commonly, superimposed bacterial infection and pneumothorax occur. Chest x-rays often show a sequence of changes with a ground-glass appearance and fine mottling in the early stage of the disease, progressing to a picture of mainly hilar linear markings in those children who recover. The histological features at lung biopsy or necropsy are described; these correlated poorly with the radiological features, steroid responsiveness, and clinical course. Lung function tests in 3 older children showed evidence of markedly reduced lung volumes in 2. Static lung compliance in 4 children in the acute stage of the illness was normal in 3 and diminished in one. The response to steroid therapy was analysed in cases from the literature and the 10 reported cases. No spontaneous remissions occurred, all the survivors having been treated with corticosteroids. In children fibrosing alveolitis is almost always a corticosteroid-responsive disease. An appropriate course of prednisolone would be of at least 4 week's, but preferably of 8 weeks' duration, at a minimum daily dose of 2 mg/kg. After improvement the steroid withdrawal should be cautious and protracted, comprising at least a year's continuous treatment.

A disorder caused by congenital ciliary dysfunction occurs in dogs. Most of the clinical signs are directly or indirectly attributable to immotile or dyskinetic cilia and spermflagella. Due to severely impaired mucociliary clearance, a continuous mucoid nasal discharge and intermittent sneezing and coughing are typically observed during the neonatal period. Recurrent bacterial rhinosinusitis and bronchopneumonia usually start within a few weeks of birth. Hypoplastic nasal sinuses and atresia of the frontal sinuses are variable features of the disease that may be caused by neonatal colonization of these structures by specific bacteria. Bronchiectasis is an acquired lesion resulting from chronic inflammation and obstruction of airways. A secretory otitis media is caused by dysfunction of the cilia in the middle ear, and is manifested in some dogs by sclerotic tympanic bullae. Male infertility is caused by live, but immotile to hypomotile spermatozoa; however, unexplained oligospermia and azoospermia have been reported. Hydrocephalus and situs inversus are common but variable features of the disease; the genesis of these lesions has not yet been determined. The probable mode of inheritance is autosomal recessive, but dominant mutations cannot be excluded. The diagnosis can be confirmed by demonstrating the absence or near absence of nasal or tracheal mucociliary clearance and the presence of a specific ultrastructural lesion in a large percentage of cilia from multiple sites (airways, middle ear, or oviduct). The ultrastructure of sperm flagella should mirror that of the cilia. Not all dogs have ultrastructural ciliary lesions, and in these cases, results of in vitro analysis of ciliary activity may be highly suggestive, if not diagnostic. In dogs without mucociliary clearance in which structural and functional analysis of cilia are not diagnostic, confirmation of congenital ciliary dysfunction can be established only by ruling out other diseases with similar signs (e.g., congenital immunodeficiency syndromes). The clinical course in an longevity of affected dogs are highly variable. Appropriate antibiotic treatment and pulmonary physical therapy may result in prolonged survival, although cor pulmonale and reactive systemic amyloidosis are potential sequelae of chronic hypoxia and chronic bacterial infection of the airways, respectively.

Bronchiectasis has come to be considered as a type of sinobronchial syndrome in Japan, but there exist some cases without chronic sinusitis. We studied the clinical features of 14 cases of bronchiectasis with definitely normal paranasal sinus roentgenogram, diagnosed during the past ten years. There were eleven middle-aged women and three men. Ten patients (71%) complained of hemoptysis, one (7%) of dry cough, one (7%) of productive cough, and the two (14%) had no complaint. In seven patients (50%) CT and bronchography showed localized cylindrical bronchiectasis in the right middle lobe and/or left upper lobe lingular division. They were considered to be middle lobe lingular syndrome. Three patients (22%) with localized varicose or cystic bronchiectasis had a history of pneumonia or pertussis in their infancy, so their bronchiectasis were considered secondary to infantile bronchopulmonary disease. Two patients (14%) had diffuse cystic bronchiectasis and were almost asymptomatic. They might be cases congenital bronchiectasis or Williams-Campbell syndrome. Pulmonary function tests were normal in most of the cases and sputum culture revealed no cases of persistent bacterial infection. These clinical features are quite different from those of bronchiectasis reported as sinobronchial syndrome, in which chronic productive cough, poor pulmonary function, persistent bacterial infection, etc. are significant. So we conclude that there are two distinct groups in bronchiectasis.

The pattern of illness in 60 consecutive children with homozygous sickle cell disease who attended the Paediatric Emergency Room of a busy Lagos hospital with acute illness was studied prospectively. Their ages ranged from 3 months to 13 years with a peak in the 2nd year. There were twice as many boys as girls. The commonest symptoms were fever, limb or abdominal pain and cough, and the commonest signs were pallor and hepatomegaly. Painful crises occurred in 27, anaemic crises in 11, and a combination of these in 12 children. Infection was detected in 76% of subjects in crises. Infection was found in 82% of all the children and was mainly bacterial. The commonest infections were pneumonia (35%), bacteraemia (32%), tonsillitis/pharyngitis (17%) and osteomyelitis (8%). The predominant bacteria isolated were Klebsiella spp (38%), E. coli (23%), Staph. aureus (23%), Staph. albus (23%) and Pseudomonas spp (23%). Some children had multiple isolates. Bacterial infection was a major cause of morbidity in very young children and merits appropriate control and preventive measures in this age group. The spectrum of bacteria isolated makes it unlikely that the specific anti-pneumococcal measures widely advocated in Europe and America for young children with SCA would be appropriate in Nigeria.

Allergic rhinitis in children is often complicated by bacterial sinusitis, which can lead to chronic illness and dysfunction. Sinus disease manifests differently in children than in adults, with cough, rhinorrhea, and middle ear disease being common and pain, headache, and fever being uncommon. Sinusitis may exacerbate asthma, and as many as 70% of children with allergy and chronic rhinitis have abnormal findings on sinus x-ray studies. Nasal cytologic specimens showing large numbers of polymorphonuclear cells with intracellular bacteria are also evidence of sinusitis. Obstruction of the nasal airways by allergic rhinitis or enlarged adenoids can lead to deviations in facial growth, specifically increased facial length. With the removal of the obstruction and a return to nasal breathing, facial length may become more normal. Sinusitis in children is treated with antibiotics, usually for 3 to 4 weeks, to eliminate the infection. Adjunctive therapy with antihistamines, decongestants, cromolyn, and corticosteroids may also be helpful. Topical steroids, such as flunisolide and beclomethasone, can be very useful in pediatric patients. These steroids decrease edema and prevent the release of allergic mediators that may be responsible for an environment favoring the bacterial infection causing sinusitis.

Filaroides hirthi infection was diagnosed in 2 related Yorkshire Terriers. Dog 1 had a chronic nonproductive cough, but results of fecal flotation examination were negative. Dog 2 was a 1-year-old female progeny of dog 1. Both dogs came from the same kennel and were raised together for 8 weeks. Dog 2 had generalized demodicosis accompanied by secondary bacterial infection and had been treated with corticosteroids. Dog 2 also was given 68 micrograms of ivermectin, PO, and then 50 mg of fenbendazole/kg, PO, q 24 h for 14 days. After the 14-day treatment, results of 3 fecal examinations were negative for Filaroides sp and other parasites, and the dog improved without complications. Fecal examination of the other dogs in the kennel were negative for F hirthi.

To determine if parainfluenza type II (P2) virus infections in dogs could be used as a model for viral airways disease in children, we studied pulmonary function and histopathology in 12 P2-infected and 8 control beagle dogs. Ten infected animals developed symptoms of cough and rhinitis within 9 days of virus exposure. Histologic changes in infected dogs included ciliated epithelial denudation and peribronchial and peribronchiolar lymphocytic infiltrates involving airways of all sizes; most notably, 19 to 57% of nonrespiratory airways less than 1 mm in diameter were affected. Two weeks after the onset of symptoms, infected dogs were asymptomatic, but they had lower functional residual capacities (p less than 0.05) and lower specific lung conductance (p less than 0.05) than control dogs. Additionally, dynamic compliance did not increase with lung growth in infected dogs as it did in control dogs. These results suggest that parainfluenza type II infections can be experimentally produced in dogs (without concomitant bacterial infection), that these viral infections are similar to human viral lower respiratory tract illnesses, and that such viral infections may alter lung development in rapidly growing dogs.

Signs, symptoms, and radiographic abnormalities of sinusitis are frequent in children with asthma; it is not known whether sinus inflammation is associated with bacterial infection or other mechanisms. Eight asthmatic patients with exacerbation of asthma despite bronchodilator therapy were studied after maxillary sinusitis was confirmed by radiographs. All had cough, wheezing, nasal stuffiness, rhinorrhea and were afebrile. Four patients had headaches, and two had facial pain. Maxillary sinus aspirates were obtained, and bacterial cultures were positive in five: Branhamella catarrhalis (2), nontypeable Hemophilus influenzae (2), Streptococcus pneumoniae (1). Nose and throat cultures did not correlate with sinus cultures. All patients received bronchodilators, and four of eight patients received steroids. All were treated for 14 to 28 days with antibiotics during which seven of the eight patients improved clinically including all with positive sinus cultures. Asthma-symptoms diary scores were kept by five; all demonstrated improvement. Pulmonary-function tests improved in five of seven patients after the antibiotic and asthma therapy including the four patients with positive cultures. Sinus radiographs cleared in three, improved in three, and were unchanged in two patients after antibiotic therapy.

Legionnaires disease, which is commonly manifested as pneumonia, was only recently recognized to be a bacterial infection. Diagnosis can be difficult because Gram's stain does not readily stain the bacterium in pulmonary secretions, the organism is not readily cultured, and legionellae is not affected by many commonly used antibiotics. In a retrospective review of all of our transplant patients, we identified 14 cases of Legionnaires' disease after 101 renal transplants. The patients characteristically had high fever, polymorphonuclear leukocytosis, dyspnea and an unproductive cough accompanied by radiographic changes of consolidating pneumonia. Legionnaires' disease can be diagnosed by direct immunofluorescent antibody staining, culture on special media or increases in serum titers of legionella antibodies in surviving patients. Since the recognition of Legionnaires' disease in 1977, we have successfully treated seven renal transplant patients using erythromycin with or without rifampin.
