Correlations between skin prick tests using commercial extracts and fresh foods, specific IgE, and food challenges.

The skin prick test is the most widely used test for detecting IgE-mediated food hypersensitivity. Our study aimed to define firstly the correlations between results obtained with prick tests using commercial extracts and fresh foods, and secondly the correlations between these results and those obtained with labial and/or oral challenge. We compared the wheal diameters read at 15 min with commercial extracts and fresh foods, for four foods, in 430 children with suspected food allergy.

Microrevascularisation of the penis in vascular impotence.

Purpose: We evaluated the results of microvascular penile revascularization in impotent men and carefully selected those whose vasculogenic impotence was defined as arteriogenic impotence, veno-cavernous leakage or mixed vasculogenic impotence.

Materials And Methods: Over a period of 11 y, 114 patients were treated for vasculogenic impotence with two surgical procedures: Michal II arterial bypass (44 patients) and modified Furlow-Fisher technique of deep dorsal vein arterialization (DDVA) (70 patients). Initial evaluation included history, physical and neurological examination, hormonal level determination, pharmacological erection test, Rigiscan, duplex ultrasonography, selective pudendal arteriograpy, dynamic cavernosometry and cavernosography.

Labial food challenge in children with food allergy.

The current increase in the prevalence of food allergies appears to have several causes including better screening, improved diagnosis and changes in both the techniques used by food manufacturers and eating habits. Labial food challenge (LFC)is simple, rapid to perform and is associated with only low risks of systemic reaction. It is thus an appealing alternative to the oral food challenge (OFC) for pediatric use.

Activation of association auditory cortex demonstrated with functional MRI.

Activations in the temporal lobes previously observed using positron emission tomography and auditory stimuli were partially reproduced with functional MRI and echo-planar imaging at 1.5 T in six volunteers performing tone and phoneme monitoring tasks. Verbal processing compared to a tone recognition task significantly activated a cortical area located in the left anterior temporal region (P < 0.

Morbidity using subcutaneous ports and efficacy of vancomycin flushing in cancer.

An evaluation of totally implanted venous access systems inserted in 163 consecutive children with cancer is reported. From 1988 to 1994, 180 subcutaneous ports were inserted in children more than 1 year old. Initial diagnosis was acute leukaemia (n = 79), non-Hodgkin's lymphoma (n = 33), and solid tumour (n = 51).

Photosensitive and phototriggered pityriasis rubra pilaris.

We report a 59-year-old man with photosensitive and photodistributed pityriasis rubra pilaris. The phototriggering of the lesions was obtained by the iterative polychromatic phototest (3 times the minimal erythema dose (MED) on 3 consecutive days) and was also observed on the supra MED sites, which began the 10th day and persisted several months. Our results are comparable to those already obtained in photosensitive psoriasis, which helped us to identify the clinical similarities of photosensitivity in these two instances of dermatosis.

[Acoustic emissions from the ear].

In this paper we study the phenomenon of the acoustic emissions. This study presents two cases with different auditif pathology and their clinics applications.

The organogenesis and anatomy of vascular malformation.

According to an embryological basis, the Authors analyze the development of the vascular system and try to establish a differentiation between angiodysplasias and abnormalities. They define the characteristics of each group and make an attempt at classification. The major characteristics of differentiation are the evolutional aspects and the presence of arteriovenous fistulas.
