Hi, My wife underwent a pericardial centesis on 12/27/2016. The surgeon's procedure resulted in about 700 cc having been drained from the pericardial sac, and she was discharged from the hospital in 24 hours The fluid was later tested and no problems in the fluid were found. Prior to her surgery, she had a blood test for pre admission on 12/232016. The results of the blood test were good and her ALP was 134, and her ALT was 30. On 02/15/2017, she had another blood test. That blood test showed that her ALP was 231, and her ALT was 65. This dramatic increase of both ALP and ALT suggest that the drugs used in the hospital caused the spike. What do you think? Should we be concerned?

Hi! My period is not due for another 6 days. Last period was January 12 and lasted until the 18th. 32 day cycle, usually. Have gone up to 37 before. Well for the past 2 days, my boobs have been really sore and I've been nauseous. Not normal for my period symptoms or feelings. I usually don't get sore boobs until my period is right about to start and never nausea. Would a blood test tell me if I am pregnant since I think it's too early to test with a pee test?

Started as burning urination. Felt like I was urinating razors. Then a clear but thickish discharge started appearing at the tip of my penis. About 2 days went by, and then sores started appearing all over the shaft of the penis. I went to a doctor initially and he gave me valtrex and zithromax to treat the infections. Said I had probably had herpes and chymydia.

Took the medication and the burning urination stopped. The sores started to scab over. No pain on the sores. Just highly annoying and somewhat itchy.

I then went to another doctor just to get tested for everything. They did a urine test and a blood test. This was 9 days after I first experienced symptoms.

So here I am today, and everything on blood test and urine test came back negative. What is the likely diagnosis? And yes I have had unprotected sex in the last month or so with 1 partner.

Brief Answer:
Repeat the test after 3-4 weeks

He has ICD implanted on October 2006.He was seen recently for his complaint of bilateral edema and pain on his feet. Though the swelling does not occur at the same time. He s been experiencing the pain and swelling since August of 2010. The swelling and pain is alternating on each feet. He shows elevation on his uric acid level and responds on Naproxen. Due to his other medical condition, the provider has concern on putting him on Naproxen for a long period of time.

Bony mineralization is normal. No fracture or acute osseous abnormality is evident. The joint spaces are well maintained with minor osteophyte formation. He is presently scheduled for his ICD battery replacement on February 4, 2011. Today, I ll take him for the following lab works: Renal Panel, 24-hr Urine Protein and Creatine and Hba1c. The patient is currently taking the following medication: Micardis 40mg once a day, Coreg 6.25 Twice a day, Furosemide 80mg Twice a day, Theragran-M once a day, Zocor 40mg once daily, Singulair 10mg once daily. I am his daughter and I am the one responsible for his health care. Thank you very much for your time. I need your guidance. I have concern about his stability prior to his scheduled procedure. I know that it is a n out-patient procedure. However, I cannot afford to overlook any other possible medical condition. I look forward to your reply.

My son was discovered to have liver calcifications incidently at the age of 7. He was followed by CT scans for a couple of years but not for the last 3 as nothing had changed previously. Last year at the age of 12 he lost a signficant amount of weight (18 lbs) but had started Citalopram 10 mg just prior and they felt it to be related to that until blood tests showed him to be neutropenic. We were also told IF it was the med things would level off and weight would return. Well they havent and since that time appetite has been decreased more so than previously, gets chilled easily (teeth chatter) will occ have a fever of 100-102 which lasts only a few hours and returns to normal. We have checked blood sugars as well and noted him to have a few minimally low blood glucose readings 72 to 68 at the lowest, he develops hives all over his body which seem to just occur randomly and sometimes take days to clear even with benadryl. We took him to MD for eval. She suspected anemia and possibly a virus causing the hives and said it would pass. She did blood tests only to appease us however Ferritin came back oddly high at 312 along with elevated CRP and neutropenia again. We questioned liver involvement and she didn t agree, we went to another MD as more symptoms had developed of joint pains who felt a referral to GI should be done and ordered additional blood tests which showed again elevated CRP, ALT, AST and Ferritin 278 and again is noted to be neutropenic. Mono tests were negative as was RA and Lupus. We continue to wait to get in to see the specialist and in the meantime he has developed cramping in arms, legs and abdomen (all over not just the right side) continues with chills, has worsening fatigue, tips of fingers were cold and blue for a few hours on two occasions now and then return to normal, feels dizzy at times. What could this be? Does this sound like hemochromatosis which the doctors seem to know nothing about or is something else being missed?

re: fasting blood sugar and autonomic neuropathy. I have hyperadrenergic postural orthostatic tachycardia syndrome. mild peripheral neuropathy in my legs with pain and swelling, blurred vision. I am hearing from other friends with POTS that they are finding overlapping sugar issues and wonder if I am in that category. I have many symptoms, which I won t go into regarding my condition, but would like to know if there is new data out about autonomic dysfunction and prediabetes. Also, if catecholamines have anything to do with it. My norepinephrine is high standing. I began testing my glucose at home, and I have a high fasting glucose most days. 100-116. During my period, or when I am cramping it is at about 96-99. I have no other high readings throughout the day. And my a1c was normal at 5.4. But I have always craved sweets to combat my fatigue. Not as much now that I am older (41) but it was always a major factor. My question is, do you know about relationships to diabetes/prediabetes and autonomic dysfunction. And do you think I am heading towards prediabetes. Are high fasting numbers something that should concern me, considering my history with hypertension, tachycardia and neuropathy due to the POTS.
