September 2015 Arizona Thoracic Society Notes

The September 2015 Arizona Thoracic Society meeting was held on Wednesday, September 23, 2015 at the Scottsdale Shea Hospital beginning at 6:00 PM. This was a dinner meeting with case presentations. There were 13 in attendance representing the pulmonary, critical care, sleep, and radiology communities.

There were 6 case presentations:

1. Dr. Gerald Schwartzberg presented a case of a 58-year-old woman with a history of Mycobacterium avium presented with cough and malaise. CT revealed a history of lower love centrilobular nodules and scattered ground glass opacities and some bronchiectasis. Sputum revealed Aspergillus fumigatus. IgE was normal but IgA was deficient at 20 mg/dl (normal 80-350 mg/dl). She was started on itraconazole and clinically improved. Many questioned whether the Aspergillus was the cause of her pneumonia and some questioned the association of the IgA deficiency with her overall clinical picture.
2. Dr. Schwartzberg presented a second case of a 92-year-old former opera singer who had a past diagnosis of asthma but without airflow obstruction, gastroesophageal reflux disease, and myelodysplastic syndrome. CT scan revealed mosaic areas most consistent with hypoperfusion secondary to air trapping. Complete pulmonary function testing revealed only a markedly decreased DLco. She had oxygen desaturation with exercise. Clinically she did not respond to a bronchodilator. Most were perplexed as the cause of her overall clinical picture.
3. Dr. Schwartzberg presented a third case of a morbidly obese 61-year-old woman who presented with shortness of breath. CT scan showed some scattered lung nodules in her lower lobes. Laboratory evaluation including cocci serologies were negative. A needle biopsy of one of the lung nodules was nondiagnostic and she was empirically begun on fluconazole. She clinically improved. Many thought this could be possibly Valley fever and she should be followed.
4. Dr. Alan Thomas presented a 66-year-old man with a history of lymphoma about 10 years earlier who presented with some enlarging lymph nodes. Thoracic CT scan was performed as part of his evaluation and showed some areas of emphysema with scattered ground glass opacities. It was felt the radiologic pattern was most consistent with respiratory bronchiolitis with fibrosis (2).
5. Dr. Thomas also presented a case of an 82-year-old former smoker who quit about a year ago who presented with weight loss and minimal cough. Thoracic CT scan showed a large pleural mass with pleural effusion surrounding the right lung as well as pleural plaques. He did have a history of asbestos exposure in the Navy. Thoracentesis showed a nondiagnostic exudative effusion. A biopsy was performed which was consistent with a large cell neuroendocrine tumor.
6. Dr. Lewis Wesselius presented a 65-year-old man with exertional dyspnea and possible interstitial lung disease. He has a history of a Ross procedure (replacement of a bicuspid aortic valve with the pulmonic valve) and obstructive sleep apnea. Chest x-ray was unremarkable. Complete pulmonary function testing was normal. Thoracic CT scan showed peripheral reticulations especially in the lower lobes. A video-assisted thorascopic biopsy (VATS) was performed. Histology showed scattered fibroblast foci with scattered fibrosis with airway centricity. It was unclear whether this was usual interstitial fibrosis or chronic hypersensitivity pneumonitis. He was started on prednisone because his picture was felt to be most consistent with chronic hypersensitivity pneumonitis (1). Unfortunately, chronic hypersensitivity pneumonitis with features of UIP appears to carry a worse prognosis.

There being no further business, the meeting was adjourned about 7:30 PM. The next meeting will be in Phoenix at Scottsdale Shea on Wednesday, November 18 at 6:30 PM.

July 2015 Arizona Thoracic Society Notes

The July 2015 Arizona Thoracic Society meeting was held on Wednesday, July 23, 2015 at the Scottsdale Shea Hospital beginning at 6:30 PM. This was a dinner meeting with case presentations. There were 16 in attendance representing the pulmonary, critical care, sleep, and radiology communities.

It was decided to continue holding the meeting on the fourth Wednesday of the odd numbered months.

Lewis Wesselius relayed a request from the Mayo Clinic regarding a survey on how physicians in Arizona treat Valley Fever. There were no objections to using our mailing list to send out the survey.

Dr. Parides formed a committee to encourage younger clinicians to attend the Arizona Thoracic Society meetings.

Richard A. Robbins was chose as the Arizona Thoracic Society's nominee for clinician of the year.

There were 3 case presentations:

1. George Parides presented a 58-year-old woman with a past medical history of cavitating coccidioidomycosis in both upper lobes from which she had recovered. However, on thoracic CT scan she had traction bronchiectasis as well as narrowing of the inferior vena cava. It had been recommended that a vena cava filter be placed to prevent pulmonary embolism. She had no history of deep venous thrombosis. None in the audience knew of any data suggesting placement of a filter was indicated.
2. Lewis Wesselius presented a case of a 19-year-old man who presented with dyspnea and bilateral large pulmonary nodules. He had a history of smoking about 5 cigarettes per day and use of medical marijuana for sinusitis. Laboratory workup showed an elevated white blood cell count but a cANCA and cultures was negative. Bronchoscopy with bronchoalveolar lavage demonstrated alveolar hemorrhage. Open biopsy was consistent with pulmonary pyoderma gangrenosum. The patient was begun on corticosteroids and had resolution of both his symptoms and nodules.
3. Rick Robbins presented Drs. Ling and Boivin's case of a 40 year old man with a history of opioid abuse who was mechanically ventilated but failed an extubation trial (1). The videos of the diaphragm were presented along with a discussion of the diaphragm thickening fraction (DTF) assessed by ultrasound as a predictor for the success of extubation. DTF is calculated using the following formula: Thickness at end inspiration - Thickness at end expiration / Thickness at end expiration. Based on the study published by Ferarri and associates (2), they found that a DTF > 36% would provide a sensitivity of 0.82, a specificity of 0.88, a positive predictive value (PPV) of 0.92 and a negative predictive value (NPV) of 0.75.

There being no further business, the meeting was adjourned about 8 PM. The next meeting will be in Phoenix at Scottsdale Shea on Wednesday, September 28 at 6:30 PM.

May 2015 Arizona Thoracic Society Notes

The May 2015 Arizona Thoracic Society meeting was held on Wednesday, May 27, 2015 at the Scottsdale Shea Hospital beginning at 6:30 PM. This was a dinner meeting with case presentations. There were 16 in attendance representing the pulmonary, critical care, sleep, and radiology communities.

Ms. Georgann VanderJagt, RN, MSN gave an update on clinical trials at Dignity Health including idiopathic pulmonary fibrosis and alpha-1 antitrypsin deficiency. To contact Ms. VanderJagt call her office at 602-406-3825, her cell at 602-615-2377 or by email at georgann.vaderjagt@digniftyhealth.org.  

Dr. Michael Smith, the surgical director for the lung transplant program at Dignity Health, gave an overview of their lung transplant program. They are currently the fifth busiest transplant program in the US.  They have done 46 lung transplants so far this year. They are on a par with UCLA in number of transplants and survival has been at the National average. Average wait time is only abut 2 weeks. He also discussed recent and ongoing transplant protocols. To contact Dr. Smith call 602-406-7564.

There were 4 case presentations:

1. Jud Tillinghast presented a case of a large man who was short of breath. His CT scan showed multiple calcifications in the lower lobes. It was felt that clinically he was most likely aspirating as a cause of the calcifications.
2. Gerald Swartzberg presented a case of a large man who had some minimal dyspnea and an elevated right hemidiaphragm. His chest x-ray showed consolidation in this right lower lung. He had been seen at the Mayo Clinic and Dr. Lewis Wesselius reviewed his pathology from a needle biopsy of a right lower lobe nodule which was nonspecific. Reviewing his case he also had a biopsy from Sloan Kettering in 2006 which was also nonspecific. Further history was obtained and the patient admitted he was using Vick's Vaporub in his nose since he was 7 years old. It was unclear if this was the cause of his right lower lobe consolidation.
3. Dr. Swartzberg presented a second case of a 70-year-old woman with multiple medical problems. She has a cockatiel but is remarkably asymptomatic. A chest x-ray was taken showed nonspecific lower lobe changes. Pulmonary function tests showed a reduced vital capacity but a normal to high total lung capacity. A DLCO was not able to be obtained. CT scan showed small nodules with ground glass in her lower lobes. It was felt that most likely this was a hypersensitivity pneumonitis secondary to her bird. She got rid of the bird but did not improve.  The cause of her abnormal pulmonary radiology remains unclear.
4. Dr. Wesselius presented a case of a patient with a chronic cough which had been treated with antibiotics and corticosteroids. When he as on oral corticosteroids he was perhaps somewhat better. He was seen at the University of Massachusetts without a diagnosis being made. He subsequently moved to the Phoenix area and was evaluated at the Mayo Clinic. Chest x-ray showed consolidation in his right upper lobe. On bronchoscopy he had some whitish plaques along his trachea and main bronchi. Bronchoalveolar lavage showed 89% eosinophils and his transbronchial biopsy was consistent with chronic eosinophilic pneumonia. Apparently, this association has previously been sporadically reported. He was started on prednisone and improved.

Dr. Jud Tillinghast was acknowledged as the Arizona Thoracic Society Clinician of the Year and one of the four finalists as ATS Clinician of the Year.

After a brief discussion, the membership agreed to encourage and help Nevada form a state thoracic society.

There being no further business, the meeting was adjourned about 8 PM. The next meeting will be in Phoenix at Scottsdale Shea on Wednesday, July 22 at 6:30 PM.

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.

January 2015 Arizona Thoracic Society Notes

Dr. Judd Tillinghast was presented a plaque in recognition of being chosen by his colleagues as the Arizona Thoracic Society Physician of the Year In 2014.  

Dr. Rajeev Saggar made a presentation entitled "Pulmonary fibrosis-associated pulmonary hypertension: a unique phenotype".  This presentation focused on new echocardiographic methods of assessing right ventricular (RV) function and the pathophysiology of RV dysfunction. Dr. Saggar presented data from a paper he authored on parenteral treprostinil in patients with idiopathic pulmonary fibrosis and pulmonary artery hypertension which was published in Thorax (1).

There were 2 case presentations, both from the Phoenix VA by Dr. Elijah Poulos:

1. A 65 year-old man presented with cough and chills.  His past medical history included multiple myeloma treated with chemotherapy, radiation therapy to spine and bone marrow transplant.  He had a prior vertebroplasty. His symptoms did not improve with doxycycline.  Computerized tomography angiography was done and showed areas of unusual abnormalities in lung that were very high density.  This was determined to be cement emboli from the prior vertebroplasty (pulmonary cement emboli, PCE) which has been previously reported as a complication of this procedure.  The appropriate treatment options in this case were discussed.
2. A 69 year-old man presented with dyspnea on exertion over past couple of years.  Chest radiography showed abnormal areas of central fibrosis with sparing of the lung periphery.  A thoracic CT scan also demonstrated central fibrotic/cystic changes.  The patient subsequently admitted to use of crack cocaine which started at age 59.  There are reports of similar pulmonary fibrosis associated with use of crack cocaine (2).  The possible pathophysiologic mechanisms were discussed.

The next meeting in Phoenix will be at Scottsdale Shea on Wednesday, March 25 at 6:30 PM.
