March 2015 Arizona Thoracic Society Notes

The March 2015 Arizona Thoracic Society meeting was held on Wednesday, March 25, 2014 at the Scottsdale Shea Hospital beginning at 6:30 PM. This was a dinner meeting with case presentations. There were 14 in attendance representing the pulmonary, critical care, sleep, radiology and oncology communities.

Dr. Richard Robbins made a presentation entitled "The History of Exhaled Nitric Oxide Measurement" focusing on the development of exhaled nitric oxide in the early 1990's.

There were 3 case presentations:

1. Sandra Till, a third year pulmonary fellow at the Good Samaritan/VA program, presented an elderly man admitted to the Phoenix VA with an exacerbation of chronic obstructive pulmonary disease (COPD). His CT findings showed with centrilobular emphysema, bronchial edema, and scattered ground glass opacities. It was felt that the CT findings most likely represented a bronchiolitis from his exacerbation of COPD.
2. Richard Robbins presented a 49 year old man with a positive PPD and Gold QuantiFERON who has extensive psoriasis and had biological therapy with etanercept recommended. He had an extensive past medical history of diabetes and sleep apnea secondary to obesity which resolved with gastric bypass. His liver was palpable at his right costal margin and his liver enzymes were mildly elevated. Chest x-ray was normal. Most felt that therapy for latent tuberculosis was indicated with some recommending isoniazid, others recommending rifampin and others recommending both drugs. He was treated for one month with isoniazid and his liver enzymes all declined into the normal range. He has begun etanercept and 6-9 months of isoniazid therapy are planned.
3. Stephanie Fountain, a second year internal medicine resident from the Good Samaritan/VA program presented an elderly man with a history of adenocarcinoma of the pancreas treated with chemotherapy and radiation in Chicago just prior to moving to Phoenix. He presented with abdominal pain secondary to an ileus which spontaneously improved. A CT scan performed during the abdominal evaluation showed multiple small nodules and some scattered ground glass opacities which was reminiscent of idiopathic interstitial pneumonia with cystic changes. Biopsy showed adenocarcinoma which special stains were most consistent with a pancreas primary. Discussion ensued about this unusual presentation CT presentation of metastatic pancreatic cancer.

The next meeting in Phoenix will be at Scottsdale Shea on Wednesday, May 27 at 6:30 PM.

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.
