Although the definition for a confirmed case is more specific, all variables analyzed are similar for confirmed and probable cases except clinical presentation.
Based on clinical presentation and probable etiology, HUS is commonly divided into diarrhea-associated HUS (D+HUS) and non-diarrhea-associated HUS (D−HUS), also called atypical HUS.
Probable hypotheses for this presentation would be direct compression of the spinal cord from the psoas abscess or vascular compromise of spinal cord secondary to thrombosis or septic embolisation from the infected psoas muscle or due to exotoxin induced myelitis and demyelination.
The specific presentation of probable late Lyme disease, including untreated patients with a history of subjective symptoms and a positive IgG immunoblot, differs in two important ways from those meeting criteria for post-treatment Lyme disease syndrome (PTLDS), a disease category recently added to the Infectious Disease Society of America IDSAA) guidelines [ 10].
A probable etiological mechanism for the presentation of such a myopathy in the elderly is the accumulation of mitochondrial tRNA pathogenic mutations that affect aging tissues [ 9].
Patients who agreed to participate in the study were similar in terms of age, sex, and temperature (on clinic presentation) to all probable SARS case-patients without a history of contact with another SARS patient (n = 1,091).
However, preliminary information relating a probable time course for the presentation of statin-induced myopathy supports the need to monitor symptoms and CK levels carefully, particularly in the first year, so that timely reassurance and intervention can be instituted where necessary.
Rational credibility, or belief that is warranted or justified, Lewis thought, is probable on the evidence, but the presentation of his views on probability was complex and sometimes confusing.
In this analysis, we did not apply this exclusion criterion to allow for a complete presentation of suspect and probable cases captured and monitored by national surveillance.
Though rare, the amnestic presentation diagnosed clinically as probable Alzheimer's disease has been observed across many in the series [ 20, 21, 25, 26], including one analysis focused on late-onset Alzheimer's disease [ 34].
