[Supra trochlear femoral erosions. Their relations with gonarthrosis and chondrocalcinosis (author's transl)].

Studying one hundred cases of simple gonarthrosis we found only one supra trochlear femoral erosion (STFE). Such a lesion was discovered in 14 cases among 150 chondrocalcinosis with arthrosic lesions. The cases involving STFE trend to a commun marked chondro-osteolytic evolution. The caracteristic patella sizes show clearly that STFE is not in relation with en anomaly of patella (patella alta...). The upper osteophyte of the patella presents only a minor importance in the formation of STFE. This STFE formation begins probably with a progressive chondro-osteolysis of patella and trochlea. Then, appears a progressive nipping between the upper point of patella and the supra trochlear femoral bone.

[Herpes gestationis. Apropos of 2 cases].

Herpes gestationis is an autoimmune disorder specific of pregnancy. The authors report two cases of this condition with distinctive clinical and immunological features. Both the pathogenesis and the nosologic connections between Herpes gestationis and Bullous pemphigoid are reviewed and discussed.

[Incontinentia pigmenti. Apropos of a new case].

This paper describes a new case of Incontinentia Pigmenti in a newborn. This genodermatosis develops mostly in females and three clinical stages are recognized. Other ectodermal abnormalities may be associated with a risk for the prognosis. The clinical, histological features and differential diagnosis are discussed.

[Computerized tomography of the distribution of N-isopropyl-p-123 iodoamphetamine in cerebrovascular pathology. Comparison with studies using the 133-xenon inhalation method].

123Iodo-Amphetamine (IAMP) brain distribution was studied with a specially dedicated multilevel tomographic system in 30 patients with vascular ischemic (18) or hemorrhagic (12) disorders. Results were compared with clinical data, CT scan and rCBF measurement obtained by the 133Xe continuous inhalation method. Abnormalities with IAMP were found in 27 cases, in good agreement with the results obtained by the Xenon inhalation technique in 21 studies from the 22 where that method was possible. For 80% cases there was also a good agreement between the results obtained by the IAMP and CT scan: one case normal, and 23 observations with abnormalities. This is true for the localization of lesions, but IAMP appears able to shown remote abnormalities, i.e. crossed cerebellar diaschisis or functional deactivation, in the absence of CT scan lesions in the corresponding areas. This is of particular interest in the protracted regressive ischemic neurologic disorders (PRIND): CT scan were normal in all five observations but IAMP showed abnormalities in four cases. IAMP is however very expensive, so it has to be used only when 133Xe inhalation is technically impossible.

[Induced hypocalcaemia test using salmon calcitonin as a means for the evaluation of osteoclastic activity (author's transl)].

The authors measured the degree of hypocalcaemia (delta Ca S), hypophosphataemia and the fall in urinary hydroxyproline excretion induced by an intramuscular injection of 100 MRC U of synthetic salmon calcitonin (S.C.T.) during the 24 hours following the injection. In 15 control subjects, the fall in plasma calcium was slight ( - 2.1 +/- 0.9 mg/l) but significant. In bone diseases involving hyperosteoclastosis, the degree of hypocalcaemia was much greater: 10.6 +/- 1.1 mg/l in 24 cases of Paget's disease, - 9.0 +/- 1.6 mg/l in 5 cases of diffuse malignant disease of bone, - 8.0 +/- 1.4 mg/l in 6 cases of primary hyperparathyroidism and - 3.5 +/- 0.8 mg/l in 13 cases of algodystrophy of the limbs. In the subjects studied as a whole there was a significant linear relationship between the delta Ca S and the extent of the trabecular surfaces of osteoclastic resorption, but not between delta Ca S and total 24 hour urinary hydroxyproline excretion. The S.C.T. hypocalcaemia test would appear to be a simple means for the evaluation of osteoclastic activity within the skeleton, and thus to select those bone disorders which should respond to antiosteoclastic therapy (calcitonin, diphosphonates).

[Hypophosphatemic vitamin D resistant osteomalacia with parathyroid adenoma (author's transl)].

The authors report a new case of parathyroid adenoma associated with hypophosphatemic vitamin D resistant osteomalacia. These troubles were simultaneously found. Major and isolated phosphate tubular loss was improved neither by parathyroidectomy nor vitamin D or 25 OHD therapy. On the contrary 25 OHD associated with oral phosphate intake was clinically, radiologically and histologically efficient. The actual pathogenic concepts about this affection are reviewed.
