[Peritonsillar abscesses (quincy)].

Objectives: To study the circumstances of diagnosis, the supporting factors, the bacteriology, and the therapeutic management of peritonsillar abscesses (quinsy).

Material And Methods: This was a retrospective study over a period of 10 years in 98 patients hospitalized in an ENT and Head and Neck Surgery department for peritonsillar abscess.

Results: Ninety percent of cases of peritonsillar abscesses complicated angina.

A histological investigation on early tissue response to titanium implants in a rat intramedullary model.

Miniature grade 1 titanium screws were inserted in the tibias of 12 mature Wistar rats. Animals were sacrificed at 4, 7, and 21 days postimplantation. A combination of two morphological approaches was used to examine the tissue response to implants.

[Hearing status of Robin sequence patients].

Objective: To determine wether Robin sequence is a risk factor for conductive and/or sensorineural hearing loss.

Patients: 13 children with type III Robin sequence, admitted in our institution between 1984 and 1997 for tracheotomy were enrolled in this retrospective study.

Methods: Each child had several audiological evaluations including subjective and objective methods adapted to their age.

[Ostial stenosis of the common trunk of the left coronary artery 20 years after mediastinal irradiation].

A 43-year-old woman with no risk factors received mediastinal radiotherapy of 35 Grays at the age of 23 years for Hodgkin's disease, followed by cure of the neoplastic disease. Twenty years later, following a threatened infarction syndrome, coronary angiography revealed ostial stenosis of the left coronary trunk. The course was rapidly unfavourable immediately following the examination.

[Value of the exercise test after aortocoronary bypass].

The 100 patients who underwent an exercise test and a follow-up coronary arteriogram at a mean interval of 10.1 months after an aorto-coronary bypass had suffered preoperatively from incapacitating angina 50%), a threatened infarction syndrome (35%), or Prinzmetal's angina (15%). The majority had a single bypass graft (72%), but 28% had two or three grafts.
