Pulmonary Madurella mycetomatis mycetoma secondary to knee eumycetoma, Senegal.

Mycetoma is a neglected tropical disease which is endemic in Senegal. Although this subcutaneous mycosis is most commonly found on the foot, extrapodal localisations have also been found, including on the leg, knee, thigh, hand, and arm. To our knowledge, no case of blood-spread eumycetoma has been reported in Senegal. Here, we report a case of pulmonary mycetoma secondary to a Madurella mycetomatis knee eumycetoma. The patient was a 41-year-old farmer living in Louga, Senegal, where the Sudano-Sahelian climate is characterised by a short and unstable rainy season and a steppe vegetation. He suffered a trauma to the right more than 20 years previously and had received treatment for more than 10 years with traditional medicine. He consulted at Le Dantec University Hospital in Dakar for treatment of a right knee mycetoma which had been diagnosed more than 10 years ago. He had experienced a chronic cough for more than a year; tuberculosis documentation was negative. Grains collected from the knee and the sputum isolated M. mycetomatis, confirmed by the rRNA gene ITS regions nucleotide sequence analysis. An amputation above the knee was performed, and antibacterial and antifungal therapy was started with amoxicillin-clavulanic acid and terbinafine. The patient died within a month of his discharge from hospital.

Systemic air embolism in a fungal pneumonia patient with lung cavities formation and review of literature.

Systemic air embolism is a rare but potentially fatal complication related to many factors. The purpose of this article is to alert clinicians once patients occurs an abnormal neurological and cardiovascular status, following minor traumatic treatment, air embolism should be considered. A 20-year-old man who presented with fungal pneumonia with lung cavities formation was admitted to an intensive care unit (ICU) and received positive airway pressure ventilation. Four days later, the fungal pneumonia was improved, but the patient's blood pressure and arterial oxygen saturation deteriorated, so computed tomography (CT) scans were preformed to reevaluate him. The scans detected air embolism in the left atrium and ventricle, ascending aorta, aortic arch and its branches (right brachiocephalic, bilateral common carotid and right subclavian arteries), descending aorta and right coronary artery. A CT scan of the abdomen revealed air in the spleen, cauda pancreatic, superior mesenteric artery and right external iliac artery. The patient died two days later from multiple organ dysfunction. We suggest that vascular air embolism should be considered under mechanical ventilation when patients' neurologic and cardiovascular status deteriorates, and hyperbaric oxygen therapy should be conducted immediately.

Itraconazole for the treatment of pulmonary aspergillosis in heart transplant recipients.

The objective of this study was to evaluate the effects of itraconazole as a first choice drug in the treatment of pulmonary aspergillosis in heart transplant recipients. Heart transplant recipients suffering from invasive pulmonary aspergillosis were included in this study. Group 1 included 4 patients treated with i.v. itraconazole (Janssen Pharmaceutica) 400 mg daily, as a first choice drug for 28 d. Itraconazole was discontinued and amphotericin-B was started before the 28th day if clinical or radiographic worsening was observed. Group 2 included 3 patients treated with amphotericin-B as a first choice drug. Itraconazole was discontinued in all patients of Group 1 after 12-26 d of treatment because of radiographic worsening (n = 3) or combined clinical and radiographic worsening (n = 1). Subsequent treatment with amphotericin-B resulted in improvement of all patients. On a 5-yr follow-up period no relapse of aspergillosis was observed in 3 of them. The fourth patient expired from cerebral hemorrhage. The 3 patients of Group 2 treated with amphotericin-B showed a gradual improvement, and all were doing well on a 2-yr follow-up. In conclusion, in our study population consisted of heart transplant recipients amphotericin-B was superior to itraconazole in the treatment of invasive pulmonary aspergillosis.

Topical treatment of pulmonary aspergilloma by antifungals. Relationship between duration of the disease and efficacy of therapy.

Twelve patients with aspergilloma were treated with intracavitary or endobronchial administration of antifungals. Patients with successful therapy had significantly shorter mean duration of the disease course (3.6 months) than the less effective group (44.4 months, p < 0.01). Minimal inhibitory concentrations of antifungal agents against isolated strains of aspergilli were considerably lower than estimated intracavitary concentrations of the antifungals. A pathologic examination suggested that the old mycetoma was for the most part comprised of dead mycelial cells, against which antifungal agents were not effective. However, clinical improvement was obtained, regardless of the roentgenographic improvement. Our study suggested that early diagnosis and therapy are recommended to achieve better therapeutic effect.
