[Reactive airway dysfunction syndrome. Clinical case]. / Síndrome de disfunción reactiva de las vías respiratorias. Caso clínico.

The reactive airway dysfunction syndrome (RADS) is a type of occupational asthma without any period of latency and induced by irritants of low molecular weight. It is a clinical illness diagnosed with scarce information of prevalence in our medical service, that is why it receives a deficient treatment with more morbidity. A clinical case of a 60 year old patient is reported with a sudden, intense and long exposure to clorhidric acid and the consequent development of RADS. We performed a complete study of her signs and symptoms as well as some diagnostic tests, such as respiratory function tests and a positive test to the clorhidric acid. Once the diagnosis was confirmed, the patient was treated with high doses of corticosteroids and bronchodilators of long action for a period of three months. She had complete remission of symptoms, with normal respiratory tests and return to her every day work activities. It is important to consider that this illness in patients with respiratory symptoms and exposed to irritants should receive an appropriate treatment, which makes a better prognosis of it.

[Combined cefotaxime and amikacin for immunomodulation in the treatment of actinomycetoma resistant to conventional treatment]. / Cefotaxima más amikacina asociadas a inmunomodulación en el tratamiento de actinomicetoma resistente a tratamiento convencional.

Actinomycetoma is a chronic disease that affects subcutaneous tissue. We present a case of a patient with abdominal actinomycetoma caused by Nocardia brasiliensis resistant to different treatments over several years, who also presented phagocyte immunodeficiency. He received two cycles (23 day cycles) of cefotaxime, 1 g every 8-h, and amikacin, 500 mg every 12 hours. Immunomodulation was carried out with levamisole 300 mg per week, during 4 weeks and bacterial antigen (at a concentration of 600,000,000 bacteria per mL), twice for a week during 20 months. The importance of susceptibility testing and immunological function investigation in this type of patients is discussed.
