Winter pollinosis in Paris.

Pollen is rarely investigated as a cause of winter respiratory symptoms. Infectious coryza and asthma are particularly common during winter, and it has been shown that environmental antigens can cause at least some cases in Paris. Recent experimental data from Calhoun et al. (1991) indicate that pollen may act synergistically with viral respiratory infections, which are particularly prevalent in winter. In the present study, we investigated, in 130 consecutive patients presenting with winter aggravation of asthma or rhinitis, winter pollinosis by skin test, radioallergosorbent test (RAST), and specific endonasal challenge test. Totals of 35, 24, and 21 patients reacted positively in skin, RAST (> 0.70 PRU/ml), and endonasal tests, respectively. Clinical features during the season established the diagnosis of winter pollinosis in 20 cases; it was due to alder pollen in 10 patients and hazel pollen in 12. The positive predictive value of the skin test was only 0.57, as compared with 0.86 for the specific endonasal test, which had a negative predictive value of 1. Our results indicate that hazel and alder pollens should be prick-tested for more often as causes of winter respiratory symptoms in Paris, even if similar manifestations were absent during previous winters, were previously present during spring or summer, or were both absent in previous winters and present in spring or summer.

Comparison of costs linked to the preparation and administration of fluorouracil as a continuous infusion based on three techniques.

The approach in treatment in medical oncology and particularly in the management of solid tumours has to integrate--at least--two targets: the enhancement of therapeutic efficacy, and the respect of global budget assigned to health. Different teams are implicated in such an approach and especially physicians and pharmacists. We decided to conduct a comparative study of three techniques of administering drugs as a continuous infusion. We analysed time and materials required for the preparation in the centralized preparation unit, and for dispensing and nursing in the health units. The use of programmable pumps (CADD-1) leads to overall saving costs of 27 to 40% compared to administration by means of an infusion bag or a motor-drive syringe.

[Multicenter study of the clinical efficacy and tolerance of roxithromycin compared to erythromycin ethylsuccinate in lower respiratory tract infections].

In a double blind, randomised investigation in 193 hospitalized patients, with low respiratory infections, roxithromycin (150 mg bd) and erythromycin ethylsuccinate (1 g bd) were compared. Assessment of safety was made in 183 patients and clinical response in 155 patients. The mean duration of treatment was 11 days in both groups. Clinical effectiveness was 82% (67/82) for roxithromycin and 77% (56/73) for erythromycin ethylsuccinate. Roxithromycin appears to have a good effectiveness and to be effective as erythromycin ethylsuccinate. The safety profile is satisfactory in both groups.

[Reduction using an immunomodulator of the level of respiratory infections in chronic bronchitis].

Fifty-six patients with recurrent bronchopulmonary infections associated with chronic bronchitis were randomly allocated to 2 groups, to assess whether treatment with an immunomodulator, Diribiotin CK, could enhance resistance to infection. The double-blind, placebo-controlled prospective trial over a 9 month period showed that this immunomodulator was well tolerated and significantly reduced the rate of respiratory tract infection. The drug also significantly reduced the prescribing of antibiotic medication and the rate of absenteism from work. These effects have been demonstrated in a rigorously designed clinical study. This is the first time that a clear clinical activity has been attributed to an inducer of soluble mediators of immunity.

[Occupational asthma caused by formalin in a hospital milieu. Apropos of 3 cases].

Three cases of formalin-induced occupational asthma observed in 2 hospital nurses and 1 hospital medical secretary are reported. The characteristics of this type of occupational asthma which seems to be infrequent, probably because it is often undiagnosed, are described. The prognosis is often severe, even after discontinuation of exposure to the risk. These patients are eligible to disability pensions as compensation for occupational disease.

[A case of diffuse pulmonary amyloidosis associated with peripheral neurologic signs].

The authors report a case of well-tolerated and prolonged diffuse parenchymal amyloidosis of the lungs associated with signs of peripheral neuropathy. The latest classifications of amyloidosis generally and of bronchopulmonary amyloidosis specifically are reviewed. The problems raised by this particular case, and notably its relation with the neurological signs observed, are discussed.

[Focus on Kartagener's syndrome. Apropos of a case].

Kartagener syndrome, identified 40 years ago, is an obstructive bronchopulmonary condition of early onset which rapidly becomes chronic and linked to immobility of the bronchial cilia. This clinical entity is based upon a kinetic problem secondary to ultrastructural abnormalities of the cilia. Current techniques for the study of ciliary movement and electron microscopy in particular are sufficiently accurate to be able to link certain ciliary abnormalities to particular clinical manifestations. Although it is a frequent neonatal condition, Kartagener syndrome may be compatible with prolonged survival. The authors report a case in an adult, with a favorable course, and give an updated review of the condition.

[A case of acquired immunodeficiency syndrome (AIDS) in a homosexual].

There is increasing number of cases of acquired immune deficiency syndrome (AIDS) and in France there have been about 100 cases. The authors report one case who died within 10 months. The patient presented a Pneumocystis carinii pneumonia, extensive peri-anal herpes, gastro-intestinal candidiasis and, in the final stage, severe diarrhoea. In the context of this case, the authors review the principal manifestations of this new clinical entity.

[Haemophagocytic sinus histiocytosis or Destombes-Rosai-Dorfman syndrome (author's transl)].

Haemophagocytic sinus histiocytosis usually presents as cervical lymphadenopathy developing in a context of severe inflammatory reaction. The lymph nodes contain numerous large cytophagic histiocytes capable of absorbing all kinds of blood cells, and diffuse plasmocytic infiltrates. Other organs may be involved, notably the skin and bones, as in the case presented here. The course of the disease if prolonged, irrespective of the treatment administered.

[Cefotaxime in bronchopulmonary infections (author's transl)].

Thirty-nine patients, 17 to 80 years old, were admitted to a pneumology department. The diagnosis was acute serious or severe respiratory tract infection in 25 patients, exacerbation of chronic bronchopulmonary infection in 6, purulent pneumonia in 4, purulent bronchitis in 4. 28 infecting organisms were identified: Gram-positive cocci (Pneumococcus: 6, Streptococcus: 8. Staphylococcus: 1) and 6 Haemophilus influenzae (3 of which were associated with 1 Pneumococcus) 7 Enterobacteria (isolated or associated). Local, biological and systemic tolerance was generally very good in the majority of patients. Cefotaxime at a daily dose of 2 g intramuscularly for 12 days, showed very good efficacy in the treatment of various bacterial infections of the lower respiratory tract. The activity was evident against a variety of organisms in respiratory infections. The in vitro results of the antibiogram which indicated a superiority of cefotaxime in some cases on other antibiotics currently used in these indications were confirmed by the clinical results.

[Observation of a pulmonary histoplasmosis with Histoplasma capsulatum (author's transl)].

From an observation of pulmonary histoplasmosis with Histoplasma capsulatum in a Haiti woman living in France for 2 years, the authors recall the mycological and epidemiological data of this fungus as well as the main clinical radiological and biological signs of the disease. Because of its tendancy to dissemination, histoplasmosis can have a bad prognosis. It is difficult to diagnose in our countries and facing a chronic pulmonary form, a diagnosis of tuberculosis is often thought of. But its possibility is to be envisaged in case of a journey in countries of endemia, and the disease should be confirmed by: -- several samplings to trace the fungus, bringing the mycological prove of the disease; -- serum uses; -- modalities and difficulties of the treatment by Amphotericin B are also recalled.
