Sounds like a: Polyp report, but it would help to know where the biopsy was taken (what organ). Translation: its cancer, it needs to be removed, it is of low risk, but if indeed colon, lymph nodes need to be evaluated. An endoscopic ultrasound may better describe nodes and depth of invasion, particularly if a rectal polyp. ...Read more

Gram Stain (Definition)

The two major families of common bacteria are distinguished by the chemistry of their walls, specifically the ability of iodine to mordant their staining with crystal violet and prevent its being removed with strong solvent. Gram positives include staph and strep, while gram negatives include e. Coli. The stain has been in use for around 150 years and remains the ...Read more

How can type 1 inner ear decompression sickness be differentiated from combined hypothermia, overexertion, and exhaustion? Normal dive, 47ft for 38min with an ascent rate of 58 ft/min. Flooded drysuit in 38f water combined with 200 yd hike uphill with 80

Inner : Inner ear dcs is an extremely rare form of dcs and is not likely based on your dive profile. It is most commonly seen in deep dives with heliox mixtures (edmonds et al, diving and subaquatic medicine, 2002) and may be associated with changes of breathing gas at deep depths as a result of isobaric counterdiffusion (brubakk and neuman, physiology and medicine of diving, 2003), neither of which was present in your dive history. Additional history with regard to the onset of symptoms (during the dive, immediately after dive, delayed onset after dive) could help to differentiate iedcs from other etiologies. It would also be helpful to know whether the symtoms have improved or resolved, and if so, when. Physical examination would provide helpful information in making an accurate diagnosis. Iedcs can be associated with acute sensorineural hearing loss, vertigo and tinnitis (ringing in the ears). Inner ear barotrauma may present with many overlapping symptoms, so direct visualization of the ear drum and hearing tests would be mandatory before a diagnosis of iedcs can be made. Although i believe that iedcs is very unlikely in your case, the only way to be sure is to be examined by a qualified physician. ...Read more

CULT & GRAM STAIN SPUTUM ,is this type of test is good to look for  actinomyces ,mold and fungis?I

Need more info: This organism can be difficult to isolate since they are facultative anaerobes, but the Gram's stain of clinical materials is usually very very suggestive, depending upon the site from which the specimen was obtained. This is a common cause of osteomyelitis of the bones of the jaw. Routine cultures are not a good way to look for molds and other fungi except for yeast-like fungi. Good luck. ...Read more

What is the best treatment for color differentiation difficulties?

What is the best treatment for color differentiation difficulties?

Depends: Tooth whitening is the first non-invasive choice. You can selectively whiten darker teeth if you want. Stay away from the one hour in office whitening as it is the least effective, most expensive, most side effects. And the light used with it has no effect. In my office we also offer internal bleaching if root canal treated teeth. As a last resort porcelain veneers can be done. ...Read more
