Management includes histopathologic analysis, identification of etiologic factors
, and attempts to alleviate or eradicate these factors.
If there are previously determined etiologic factors
(allergen materials, etc.) that cause DG, those should be eliminated and oral hygiene practices should be improved.
Falling as a result of walking or running was the most common etiologic factor
. Subluxation was the most common type of trauma.
Consider traumatic brain injury as an etiologic factor
in patients with personality changes.
Possible environmental, occupational, and other etiologic factors
for Parkinson's disease: a case-control study in Germany.
Using human papillomavirus (HPV) testing is likely to replace Papanicolaou (Pap) testing for primary screening for cervical cancer for a variety of reasons--detection of the etiologic factor
should predate the development of disease; urine testing for HPV may remove patient barriers to screening; and reduced interpretation error.
From these reports it is evident that the organism traverses the gastrointestinal tract, and the investigation of H pylori in these sites will assume increasing importance, since its presence may be an etiologic factor
in inflammatory lesions of the gut.
A: Early sexual activity is the most significant etiologic factor
in the causation of cervical cancer.
An etiologic factor
was identified in 20 patients (40%) (upper respiratory tract infection in 4 patients, vestibular neuritis in two patients, head trauma in three patients, long-term bed rest in two patients, otosclerosis surgery in four patients, bone anchored hearing aid implantation in one patient, and migraine in four patients), and 60% of the cases were accepted as idiopathic or primary BPPV.
Although UVR is the primary extrinsic etiologic factor
in BCC carcinogenesis, this association is not straightforward.5 Compared with cutaneous SCC, the relationship between chronic UVR exposure and BCC is relatively modest5 and even association between morphologic markers of cutaneous photo-damage and an increased risk of BCC has been proven only moderate.6
Trauma was found to be the main etiologic factor
in TMJ ankylosis( n=46, 92%), followed by infections (n=3).
Prognosis depends on cause, the interval between clinical spasm and hypsarrythmia, rapidity of start of treatments The prognosis is better in the idiopathic or cryptogenic cases without known etiologic factor
, and those having normal development status before the onset of the spasm, and normal neuroimaging prior to therapy Earlier studies, observed that in the subgroup of cryptogenic patients, a delay in initiation of treatment may be associated with worse outcome.
