August 21, 2007. A new rule from the Department of Homeland Security (DHS) is set to take effect that establishes procedures for employers to follow when they receive âno-matchâ letters from the Social Security Administration (SSA).
Atypical organisms such as Mycoplasma pneumoniae, Chlamydia pneumoniae, and Legionella pneumophila are implicated in up to 40 percent of cases of community-acquired pneumonia. Antibiotic treatment is empiric and includes coverage for both typical and atypical organisms.
In certain cases, atypical cells are found to be precancerous, though many are benign and do not spread to other parts of the body. During microscopic evaluation, cells may appear abnormal even when they are benign. Atypical cells are different from normal cells in that many appear to be flat, with borders that are well-defined. Although treatment is commonly required for these atypical cells to revert back to normal, the process may sometimes take place spontaneously, despite the absence of treatment.
