Frank Billings, professor of medicine at Rush Medical College and Presbyterian Hospital in Chicago, who originally coined the term "focal infection
." Fifteen years after Hunter's trailblazing article, Billings published Focal Infection--The Lane Medical Lectures.
NTS may also present as a focal infection
. In a large study of NTS infections in New York, investigators noted that 7.4% of cases presented with focal infections
rather than diarrhea .
The manifestations of salmonellosis are classified into four categories: gastroenteritis, enteric fever, focal infection
, and a chronic carrier state .
Ectopic tooth outside the oral cavity is rarely reported in the literature (1, 2) Ectopic teeth can be asymptomatic or can form odontogenic cysts, cause degradation of the bone, and can be the source of focal infection
Possible eliciting factors of CU revealed focal infection
as the etiology of urticaria in 43% of the patients, out of which Helicobacter pylori (HP) was responsible for 60%.2 Recent observations have suggested a possible causative role of HP in few cases of CU.3 A possible association between HP gastritis and chronic urticaria currently remains to be conrmed by double-blind studies of eradication therapy.
Cheney, a staff psychiatrist, attempted to evaluate the popular theory of focal infection
as a cause of major psychiatric illness.
Staphylococcus aureus from biological samples was employed to induce focal infection
. Individual colonies were diluted to attain the turbid suspension of S.
[2,4] However, a febrile child with bacteraemia needs to be identified and treated in order to prevent progression to focal infection
and sepsis, which can be fatal.
Dental and gynaecological examination did not reveal any focal infection
. Her systemic examination was essentially within normal limits.
(9) The Rochester scale includes a good general appearance in a previously healthy child, the absence of focal infection
, and certain laboratory values (leucocyte count of 5000-15 000/[mm.sup.3], 1500 band neutrophils, urinalysis with 10 leucocytes per high power field, and 5000 leucocytes per high power field in faeces in patients with diarrhoea) as indicators of good prognosis; the negative predictive value of this scale was 98.9% for SBI and 99.5% for bacteraemia.
Immunohistochemistry has proved to be excellent immunological technique for effective identification of MG antigens in predilection tissues for focal infection
(Nunoya et al., 1997).
Although bone-anchored devices are usually well tolerated, the skin around the abutment of the device can develop local wound problems, such as granulation tissue and focal infection
. Hypertrophic scar formation may result in skin growth over the abutment, causing pain and inability to attach the processor.
