Good afternoon Doctor/ Dr Tryelaar,

My question is about myo cardial fibrosis.

In a recent Post Mortem investigation minor myocardial fibrosis (1cm) was found in the heart of a 95 year old female and was described as "there is a small focus of subendocardial scarring in the lateral wall of the left ventricle about 1 cm in diameter."

I would like to know;

1) Whether the minor myo cardial fibrosis could have impaired the functioning of the heart and if so to what possible extent?
2) Possible origins of the cardial fibrosis; for example could it be consequentially related to coronary artery atheroma with moderate stenosis a condition the deceased suffered from?
3) Whether it might be consequentialy related to the prescription of the antibiotic "nitrofurantoin" known for its posible adverse effect of pulmonary fibrosis and especially contraindicated for elderly people by the British Medcial Journal 1982 and the Beers Report 2012?

Thanking you.

I had a PA and lateral CXR yesterday. It resulted normal per the radiologist's report, with the exception of chronic, mild interstitial findings in the middle and lower lungs bilaterally. Please refer to the attached CXR. I am a never smoker. I do experience occasional DOE. What should I do next? See a pulmonologist? Have a high resolution CT scan of my chest? Undergo pulmonary function testing? I do not have insurance. Thank you.

Pulmonology question: How effective at assessing lung scarring are (a) chest x-rays, and (b) chest CT scans?

doctor1 MD

Brief Answer:
CT scan is more effective over chest x ray.

Detailed Answer:
Thanks for your question on Healthcare.
I can understand your concern.
For lung scarring, CT thorax is far superior than chest x ray.
In CT scan, HRCT (high resolution CT) thorax is more informative.
So chest x ray is...

Hello doctor (s),

I am 34y old female, unmarried. Wt: 46Kg, Ht: 5.6". I am an ovo-lacto vegetarian and I do not exercise or do any heavy physical work. I have been experiencing irregular body pain, muscle aches, mood swings and fatigue past several months. Diet is okay, don't feel loss of appetite and I consume plenty of fluids. Experiencing shortness of breath and persistent cough, inflammation in tonsils. Can't breathe when I bend my knees in fetal position. Have to take deep breaths through the mouth every few hours.

There is extreme joint pain in the knees, makes it difficult to stand or sit quickly. I did an X-ray for my right knee joint which came back completely normal but the pain still persists, I am out of breath even after climbing one flight of stairs and my legs feel limp.

There is random stomache-ache on the left side which appears and then disappears on it's own. But when it appears, it hurts causing frequent urination. A sonography done 2 months ago of the pelvis and abdomen indicated 5 fibroids.

I am experiencing a sharp shooting pain radiating in the Rhomboid Major region on my upper back right side that spreads to my chest and a sharp acute pain in my lower back that happens randomly but feels like an electric shock immobilizing me for a couple of seconds when it happens. A back MRI was done recently on suggestion by a neurologist to get to the root of my back pain and it said "Cervical lordosis is attenuated" and "Mild to moderate right paracentral disc protrusion and peridiscal osteophytes are seen at C5-6 level indenting on the anterior subarachnoid space and right C6 nerve root". He suggested some mild exercises and use of ergonomic chairs saying there was nothing much to worry. My back pain still hasn't subsided.

I had done a routine blood test just 5 months ago in July and all the values were normal except MPV (it was 7.5 at the time but it's normal now). I also did a B12 test back in July and the value was normal - 41.10.

My Hemogram done this week said "Predominantly Normocytic normochromatic with macrocytes and ovalocytes. Anisocytosis."

Are the low values from the recent blood report causing me bodyaches? Are there any additional tests that need to be in conjunction?

I have attached my reports for review. Thanks.

I have had a cough, fatigue and some breathing issues on and off since my Trip to AZ in Feb.2016.
My last "bout" has lasted since 24SEP16 to present. This last bout was horrible, I coughed up something similar to a liquid jellyfish, or rubber cement in consistency, twice (this scard me). 2 trips to ER and 2 chest xrays were clear. The only relief I get at all is from inhalers (only use when I can't breath or have wheezing) and acupuncture. I'm concerned about the cause. Could it be "valley Fever'? and what is NMT respiratory infection? My local health care system (not my PCP) is treating symptoms but not looking at the big picture.
I have an appointment to see a Pulmonary Dr. at XXXXXXX Clinic but I just found out my insurance won't cover any out of state treatments. Your advise. . .
