The prognostic significance of AgNOR counts in lymph node deposits of breast carcinomas.

Low AgNOR counts in metastatic lymph node deposits confer a longer 5-year survival rate in patients with breast carcinoma compared with those having high AgNOR counts. This was demonstrated in a series of 30 axillary lymph nodes from an equal number of patients with malignant breast disease. The beneficial effect of the low AgNOR status was independent of tumour differentiation, tumour size and the patients' age using univariate analysis, but it was related to the number of lymph nodes with metastatic disease.

[Aseptic necrosis of the femur head in congenital hip dysplasia. Radiological signs for a prediction or an early diagnosis (author's transl)].

Radiographs an patient histories of 36 children were examined in order to determine radiological signs that would allow a prediction or an early diagnosis of the aseptic necrosis of the femur head nucleus (Luxations-Perthes) during the treatment of hip dysplasia. Necrosis of the nucleus appeared in 17 joints (of 15 children). We had the following findings: a) Mikroepiphyses have a high risk (59%).

[Correction osteotomies of the knees. Factors altering the static angles on the radiographies through fault projection (author's transl)].

Comparing radiographies we have examined the degree in which the static angles of the knee are affected, because of a fault projection under the influence of some factors. We have found that an inwards or an outwards turn, even of a small degree (IQ), a bending or preexistent (pathological) anomalies, each alone or in combination, affected the right projection of the angles in a face radiography. Physiological knees possibly are presented like "varum" or "valgum" projectional.

Carcinoma on old frostbites.

Two cases of carcinoma developing on old frostbite scars of the heel are presented. A short review of the subject follows, stressing the rarity of these "secondary" tumors and their general context within the skin cancers and the tragic experience of Greece with frostbite in the campaign of 1940-1941.

[Intertrochanteric displacement osteotomy. Is displacement useful (author's transl)].

When displacement intertrochanteric osteotomy is performed for osteoarthritis of the hip, the factor "displacement" does not affect at all the pressure exerted on the articular faces of the hip (basic aim in prevention and treatment of osteoarthritis). The good effect of osteotomy should be attributed to the factor "biological stimulation" or "blood circulation". Therefore displacement should be avoided because it causes complication (pseudarthrosis) and difficulties when eventually total arthroplasty has to be performed which is (sooner or later) necessary in most cases.
