May 2013 Arizona Thoracic Society Notes

A dinner meeting was held on Wednesday, 5/15/2013 at Scottsdale Shea beginning at 6:30 PM. There were 13 in attendance representing the pulmonary, critical care, sleep, thoracic surgery, and radiology communities.

Dr. George Parides will have served his 2 year tenure as Arizona Thoracic Society President by July, 2013. However, he will be unable to attend the June meeting and for this reason Presidential elections were held. Dr. Lewis Wesselius was nominated and unanimously elected as President.

Three cases were presented:

1. Dr. Gerald Schwartzberg presented the case of a 49 year old woman with a history of Valley Fever in 2009. She was a nonsmoker and had no other known medical diseases.  However, she developed shortness of breath beginning earlier this year along with a cough productive of clear, jelly-like sputum. Her physical was normal. Pulmonary function testing revealed restrictive disease with significant improvements in the FEV1 and FVC after bronchodilators.  Eosinophils were increased in her CBC at 12%. IgE was moderately increased at 286 IU/ml.  Chest x-ray was normal. A high resolution thoracic CT scan revealed scattered bronchiectasis and mucoid impaction.  Some speculated that this could be a case of allergic bronchopulmonary aspergillosis (ABPA) although all agreed that the level of IgE was lower than commonly occurs with ABPA. It was felt that an Aspergillus specific IgE might be useful. It was also suggested that the coccidiomycosis might have caused the bronchiectasis, noting that mycosis other than Aspergillus sp. may cause the syndrome similar to ABPA which has been termed allergic bronchopulmonary mycosis.
2. Dr. Jud Tillinghast presented a case of 45 year old woman who worked as a nurse practioner. She had developed rheumatoid arthritis a few years earlier and was being treated with plaquenil and steroids. Recently she had developed shortness of breath. A few squeaks were normal on auscultation of the lungs. Pulmonary function testing was normal. However, a thoracic CT scan revealed a mosaic pattern consistent with air trapping. An open lung biopsy was performed and was consistent with constrictive bronchiolitis. The biopsy did not show inflammation but obliteration of the small bronchioles. Considerable discussion centered on treatment with most agreeing that there were no known efficacious treatments. 
3. Dr. Allen Thomas presented a case of a 72 year old man with 2 small pulmonary nodules discovered incidentally in Northern California. However, at the time of discovery he was in the process of moving to Arizona and presented a year later. Follow up thoracic CT scan revealed multiple small nodules and mediastinal nodes. Mediastinoscopy revealed noncaseating granulomas. A repeat CT showed that the mediastinal nodes have resolved but the nodules persisted. A PET scan showed markedly enhanced uptake by the nodules and in the mediastinum raising a question of carcinoma. Most felt that this was likely a manifestation of sarcoidosis and not necessarily an indication of cancer.

There being no further business the meeting was adjourned at about 8 PM. The next meeting is scheduled for Wednesday, June 26. The July meeting will be in Tucson on July 24^th at 6:30 PM. Location to be determined.
