Can a nasal steroid spray mask the symptoms of a bacterial infection? Treated for allergy for 1 yr, but mucus sample shows Pseudomonas Aeruginosa.

Can a nasal steroid spray mask the symptoms of a bacterial infection? Treated for allergy for 1 yr, but mucus sample shows Pseudomonas Aeruginosa.

Yes, if you: use it too much or too often. Now you have a bacterial infection that hopefully will respond to antibiotics, but you can also get fungus or other atypical infections. Antibiotics will not help these. You need to consult with an ENT specialist for definitive treatment. Surgery might be necessary. ...Read more

Strep pneumoniae found in blood, had meningitis.Told from sinuses, but lots of blood tests year before.Possible germs from needles/tests caused it?

No: There is no way a contaminated needle gave you a germ that sat around for a year and then decided to infect you. Once it finds a way in, strep pneumonia will multiply fast enough to make you sick within 24 hrs.The germ is actually carried in the nasal airway at various times in normal people who never get sick from it. ...Read more

Re-evaluation : Not adding up, and what is exactly meant by sputum test? and from where was that sputum collected? was it a culture or a smear, was it from upper or lower respiratory tract? it can be a contaminant. Unfortunately there is no magic bullet, you need to be re-evaluated for a cause of your symptoms, better see an Allergist/Immunologist if you have access to one where you live, good luck ...Read more

Had meningitis last year from bad sinuses. Flu symptoms recently, flu swab of nose. Can sticking the swab in nose cause new infection or meningitis?

Had meningitis last year from bad sinuses. Flu symptoms recently, flu swab of nose. Can sticking the swab in nose cause new infection or meningitis?

Flu testing : When handled properly by a medical professional, the swab is taken from a sterile package, inserted to a specific depth, swirled, removed, and placed in a culture tube. When the flu test is performed this way, it should not cause infection. Of course, if someone drops the swab on the floor first, it could pick up germs which might then cause infection. I hope you feel better soon. ...Read more

Sputum test reports heavy growth of Candida albicans and pseudomonas aeruginosa. No symptoms excpt stuffy nose and throat clearing for 2 yrs. pls help?

Sputum test reports heavy growth of Candida albicans and pseudomonas aeruginosa. No symptoms excpt stuffy nose and throat clearing for 2 yrs. pls help?

More info needed: Pseudomonas and Candida often appear when normal bacteria are suppressed by antibiotics. Have you been taking antibiotics, maybe for your stuffy nose and cough? Or have you been hospitalized recently? If you are otherwise healthy, chest xray normal (no pneumonia), and you don't have severe bronchitis, probably these results can be ignored. Discuss with your doctor or infectious disease specialist. ...Read more

Nose swab tested positive for a gram negative bacilli and cocci colony. This was causing sore outbreaks on face.Took bactroban 2x daily for 10 days. Will bactroban eliminate both? Are these types of nasal colonies recurring? Or should I be fine now?

Nose swab tested positive for a gram negative bacilli and cocci colony.  This was causing sore outbreaks on face.Took bactroban 2x daily for 10 days. Will bactroban eliminate both? Are these types of nasal colonies recurring? Or should I be fine now?

Probably unrelated: Those kinds of bacteria are not likely cause of "sore outbreaks on face". If this is due to any bacteria at all, I would be more suspicious of strep or staph. Bactroban (mupirocin) may help. However, you should also speak with your doctor about the possibility of herpes, which is an entirely different problem. ...Read more

Unusual: Most sinus cysts do not cause symptoms although it may potentially impede sinus drainage -> sinusitis if present near the sinus opening (cancer is unusual ) and unusual to cause pain. I would recommend that you consult an ENT. A positive IgE test to a mold alone is not correlated with the presence of fungal sinus infection. In many instances, these cysts may disappear with time. ...Read more

Allergy related: Probably this is "cobblestoning," which is the finding of streaks of lymphoid tissue on the posterior pharynx (back of the throat). It's caused by chronic allergy type symptoms. A doctor should be able to confirm that with a look in the back of the throat. If your allergies are bad, there are various treatments that may help, such as antihistamines or even immunotherapy. Try an allergist if needed ...Read more

Had strep. pneumoniae blood infection, treated. Got imported down feather pillows at same time. Is possible feathers transmitted germ/illness to me?

Had strep. pneumoniae blood infection, treated. Got imported down feather pillows at same time. Is possible feathers transmitted germ/illness to me?

No association: Strep pneumoniae is a normal bacteria in the environment and carried by healthy people. It isn't caught from pillows, clothing, food, etc. You either were carrying it before you got sick or picked it up from almost anyone you have been around. For sure not from your imported pillows. Hope you've recovered well. Best wishes. ...Read more

Could the dtap vaccine (whooping cough shot) interfere with the results of a CBC test?

Could the dtap vaccine (whooping cough shot) interfere with the results of a CBC test?

Stress response: Any stress will potentially effect a cbc, usually producing a mild rise in the total WBC count, dominated by mature forms. It is less likely if the CBC is drawn at the same time or soon after the shot, & more an hour or so later as the stress response kicks in. The dr ordering the test will take a mild stress effect into account when interpreting the study. ...Read more

How come throat swabs are screened for beta-haemolytic colonies?

How come throat swabs are screened for beta-haemolytic colonies?

Quick diagnosis: A rapid strep test is a quick method of identifying a specific bacteria in the back of your throat. However, if you truly have a bacterial infection, this technique will miss other causes of infection. Furthermore, there are people who carry the organism in their throats and are asymptomatic. This is simply a quick method of ruling out strep. Infection when you have a sore throat. ...Read more

2nd opinion/: The presence of IgA to Asp merely means exposure. If you have sinus & lung problems, you need to consult an ENT and another allergist who is more familiar with fungal issues especially if you have been exposed to water damage. ...Read more

Swab on surgical wound tested positive for MRSA. No antibiotics have been started. Is this contagious to visitors?

Swab on surgical wound  tested positive for MRSA. No antibiotics have been started.  Is this contagious to visitors?

It could be.: Swab cultures only tell you what is on the surface of the skin/ wound. If the site is not showing the other signs of infection( redness, swelling, warmth, drainage) then you my not have an infection. We refer to it as a colonization or contamination. Topical Bactroban (mupirocin) my help clear it. As far as passing it on I would suggest not sharing a bath towel and wash you stuff seperately from your family. ...Read more
