Estimation of the dose received by accidentally irradiated victims is based on a tripod: clinical, biological, and physical dosimetry. The DosiKit system is an operational and mobile biodosimetry device allowing the measurement of external irradiation directly on the site of a radiological accident. This tool is based on capillary blood sample and hair follicle collection.

The utility of early-phase (≤5 days) radiation-induced clinical signs and symptoms (e.g., vomiting, diarrhea, erythema and changes in blood cell counts) was examined for the prediction of later occurring acute radiation syndrome (ARS) severity and the development of medical management strategies.

Purpose: Our goal was to evaluate the five-year follow-up results of the Scorpio single radius total knee arthroplasty.

Method: We performed a retrospective study based upon a multicentre database to evaluate the minimum five-year follow-up clinical and radiological results of 747 patients (831 knees) who underwent primary Scorpio single radius total knee arthroplasty.

Results: The mean age of the patients was 71.

Well-fixed, all-polyethylene acetabular components may have to be removed in cases of recurrent dislocations, infection, or fracture of ceramic femoral heads. We describe a simple technique using acetabular reamers that allow cup thinning. Through this technique, the polyethylene rigidity is diminished considerably, allowing its easy removal without any risk of fracture, particularly of the acetabulum walls.

The paper reports a case of ureteral [correction of urethral] stenosis with ureterorectal [correction of urethro-rectal] fistula due to diverticulitis of the sigmoid [correction of sigma] which resolved following reconstruction of the urinary tract by ureterocystostomy [correction of urethrocystotomy] using a modified version of Boari's technique, with satisfactory renal functional recovery. On the basis of an analysis of the literature, the authors comment on ureteral [correction of urethral] stenosis and its etiological diagnosis.

The authors have used an original technique of repair for lateral instability of the ankle. The method utilises the fibro-periosteal covering of the lateral malleolus as a strip which is inserted either into the talus only, or into the talus and the calcaneum in cases with severe talar tilt. The advantages of this technique are to preserve the peroneus brevis tendon and to leave sub-talar joint mobility unimpaired.

Analysis of 5 cases of primary breast lymphoma highlights the marked rarity of the lesion and the extreme difficulty of pre-operative diagnosis. It is also shown that the disease generally runs a rapid course and that prognosis is usually unfavourable. The most effective treatment appears to be a combination of surgery and radiation therapy, while chemotherapy--although widely used--still requires further confirmation.
