Surgical resection and liposomal amphotericin B to treat cavitary pulmonary zygomycosis in a patient with diabetes.

We describe a 24-year-old man with type 1 diabetes mellitus and a cavitary lesion in the right upper lobe, caused by a zygomycete. Surgical resection plus liposomal amphotericin B therapy was successful. We discuss predisposing condition, clinical findings, diagnosis, and treatment of pulmonary zygomycosis.

Pulmonary mucormycosis: the first case with preoperative diagnosis and successful surgical treatment in Taiwan.

Pulmonarycosis is a rare disease, which refers to an infection by fungi belonging to the order Mucorales. This organism usually invades the skin, nose mouth, paranasal sinus, gastrointestinal tract, lung, brain, eyes and so forth. It usually occurs in patients with diabetes mellitus, hematological malignancy or other immunocompromised states. Until recently, this disease was rarely diagnosed before death. We report a case of pulmonary mucormycosis in a woman with poorly controlled diabetes mellitus. This is the first case in Taiwan of pulmonary mucormycosis diagnosed preoperatively and treated successfully by lobectomy only. Persistent pulmonary lesions resistant to antibiotic treatment in high risk patients should arouse the suspicion of mucormycosis. Prompt bronchoscopic examination, open lung biopsy and transthoracic pulmonary aspiration cytology and biopsy should be done. Surgical resection of localized lesions remains the treatment of choice.

[An effective case of a new biological adhesive agent, gelatin-resorcinol formaldehyde-glutaralhyde glue (GRFG-glue) in treating refractory pulmonary fistula following lobectomy for pulmonary aspergilloma].

We report a successful case of thoracoscopic therapy using a new biological adhesive agent, Gelatin-Resorcinol Formaldehyde glue (GRFG glue) for refractory pulmonary fistula. A 69-year-old male underwent right upper lobectomy for lung aspergilloma. Air leakage began 11 days after lobectomy. Closing alveolar fistula was performed 28 days after first operation. Relapsing air leakage began 2 days after second operation. The insertion of fibrin glue through thoracoscope at two times was not effective for refractory pulmonary fistula. But the insertion of GRFG glue was effective to close the fistula completely.

[Chronic necrotizing pulmonary aspergillosis resistant to antimycotic drugs and treated by partial pulmonary resection].

A 46-year-old man with a history of left upper lobectomy for pulmonary tuberculosis was admitted to our hospital because of dilated cardiomyopathy. During hospitalization, fever and weight loss developed. The cause was suspected to be a round mass inside a cavity and a neighboring infiltrative shadow in the left upper lung field as seen on chest radiography. A percutaneous needle biopsy was done, and examination of the specimen showed an aggregate of Aspergillus fumigatus hyphae. Fluconazole (FCZ) was injected through an intracavitary catheter every day, and was then given by mouth. Treatment with FCZ was effective temporarily. However, he was again admitted to our hospital because of lower extension of the cavity and deteriorated inflammatory findings. From the clinical course, chronic necrotizing pulmonary aspergillosis was diagnosed. Treatment with all available antifungal agents did not improve his condition. Although he had decreased cardiac function due to dilated cardiomyopathy, partial pulmonary resection was done. The cavity with the fungus ball was resected completely. As of the time of this writing, he remains free of aspergillosis.

Postpneumonectomy esophageal fistula: a combined radiological-endoscopic technique.

We report a case of a 70-year-old man who presented with a long-standing esophagocutaneous fistula following a pneumonectomy for aspergilloma. Major surgical procedures, including a pectoralis major flap reconstruction, a pedicled omental transposition and a radial forearm flap transposition, failed to obliterate the fistula. Seven years after initial surgery the esophagocutaneous fistula was successfully treated by means of a minimally invasive joint endoscopic and radiological technique. A radiographic catheter was passed through the fistula. The catheter and the guide wire were manipulated into the esophageal defect and into the upper esophagus. Under endoscopic vision, the catheter was then advanced over the guide wire and out of the patient's mouth. A T-tube was sutured to the catheter outside the mouth, pulled down through the esophagus, and into the esophageal defect and out through the chest wall, leaving the T-part of the tube within the esophagus. The patient made a good recovery and was discharged 7 days later. He was able to resume oral intake 3 weeks after the procedure.

Treatment of invasive pulmonary aspergillosis in severely neutropenic children with malignant disorders using liposomal amphotericin B (AmBisome), granulocyte colony-stimulating factor, and surgery: report of five cases.

Five children with malignancies developed invasive pulmonary aspergillosis during chemotherapy-induced neutropenia. All patients were treated with liposomal amphotericin B and human recombinant granulocyte colony-stimulating factor. Two patients did not recover from bone marrow aplasia and died from organ-infiltrating fungal invasion. Two patients who recovered from bone marrow aplasia survived after surgery of the pulmonary lesions. The fifth patient had a complete resolution of invasive pulmonary aspergillosis after neutrophil recovery without surgical intervention. We conclude that not only the antifungal treatment but also the recovery of granulocytes are important in localizing invasive forms of Aspergillus infections in patients with profound immunosuppression.
