My husband is taking mestinon, (pyridostigmine) methotrexate, and prednisone for myasthenia gravis. Are all 3 needed?

My husband is taking mestinon, (pyridostigmine) methotrexate, and prednisone for myasthenia gravis.  Are all 3 needed?

Quite possibly: About 1/3 can see spontaneous remission, 1/3 stabilize on chronic medications, and 1/3 have progressive difficulties. In appropriate candidates, minimally invasive thoracic surgery to remove thymus (thymectomy) can possibly cure or stabilize disease or decrease amount and/or types of meds.

Results: Hep C quant. : 2,802,680 
HCV log10: 6.448. Reflex to genotype was unable to determine genotype even though there was sufficient HCV RNA?

Hepatitis C virus: Sometimes it's not possible to determine the genotype of this virus, which thus makes the expected response to treatment more uncertain. This is a 'slippery virus' -there are 11 major genotypes (designated 1-11), and many subtypes (a, b, c, etc.) A hepatologist (GI subspecialist) or an ID doctor who works with Hep C patients can help you. You'll need an established relationship for treatment... ...Read more

HC worker. 1992 Hep B vac, 2004 titer & booster. 2012 labs hep B neg. Labs done last wk; now told that Hep B test is positive?? How can this be?

HC worker. 1992 Hep B vac, 2004 titer & booster. 2012 labs hep B neg. Labs done last wk; now told that Hep B test is positive?? How can this be?

Two possibilities...: Lab tests aren't perfect and sometimes can be wrong. Or maybe the negative result was from the wrong kind of test. Vaccination makes hepatitis B surface antibody (HBsAb) positive. Tests for surface antigen (HBsAg) or core antibody (HBcAb) remain negative. Most important, you can be sure you are immune and protected by the vaccine -- so no worries. ...Read more

Dose dalacin c 300 mg works correctly for infection ?

Dose dalacin c 300 mg works correctly for infection ?

Depends . . .: Whether any given antibiotic works depends upon whether the infection is caused by a sensitive bacteria. For instance, common cold is caused by a virus and thus won't be affected by any antibiotic. Anyway, dalacin c is a brand not sold in the states. Whether the generic Clindamycin will work "correctly" depends upon what caused your infection. Ask your doc for culture & sensitivity. ...Read more

(28 male) hb 11.5, hct 35.9, MCH 25.3, uibc 380, serum iron 18, iron saturation 5, serum ferritin 5. Have taken oral iron drops? Any concerns?

IDA - cause?: The best measure of iron deficiency anemia (ida) is serum ferritin (which is low here). The gold standard is a bone marrow biopsy (bmb), but that is rarely needed. The real question is what is the cause of the ida in a 28 year old male? Iron can help improve the iron stores and ability to produce rbcs and raise hgb. Need to find root cause. ...Read more
