Intravascular ultrasound of the transverse sinus in two patients with pseudotumor cerebri: technical note
No full textTumeurs malignes de la choroide. Confrontation anatomo-ultrasonographique. [The echography of ocular tumours and their microscopic architecture (author's transl)]
No full textThe echography of ocular tumours (7 malignant melanomas and 2 metastatic tumours) is presented in correlation with their microscopic architecture. A metastatic tumour presenting echographic characteristics typical of malignant melanoma was considered as such at the ultrasound test. All 7 malignant tumours were diagnosed through the ultrasound test, but it was impossible to foretell a predominant type of cell
Principes physiques et application du laser en chirurgie esthétique. [Principles of physics and application of the laser in plastic surgery]
No full textRecent advances in laser technology have expanded the surgeon's possibilities to treat various cutaneous lesions, as well as proposing a new tool for skin rejuvenation. Review of the basic physical principles of laser energy then overview of the different lasers used in plastic surgery as well as some of their clinical applications
Mastectomie et reconstruction: quelle securite, quelle attitude? [Mastectomy and reconstruction: what kind of safety, which attitude?]
No full textBreast reconstruction should be regarded as a significant part of breast cancer treatment. Immediate reconstruction has the advantages of a better cosmetic result, a better illness approach and of avoiding the need of a second major operative procedure. Immediate and early delayed reconstruction does not significantly increase the risk of local or systemic disease recurrence and the type of surgery performed should depend on the further therapy chosen. Skin-sparing mastectomy--a new technique--preserves the skin envelope and should be proposed to patients with central breast cancer
Cicatrices hypertrophiques et chéloides: quelles options thérapeutiques aujourd'hui? [Hypertrophic scars and keloids: which therapeutic options today?]
No full textHypertrophic scars and keloids are a hyperproliferative response of connective tissue to trauma. Histologically the difference between the two is that keloids invade normal tissue whereas hypertrophic scars remain confined within the original wound. A variety of treatments have been proposed, which we will review according to their efficiency. Prevention of pathological scarring will also be discussed, and we will present our current attitude to treat these scars. As a surgical treatment for keloids, we have been using the intralesional technique which we think gives better results
Le melanome de la papille, nouvelle observation. [Malignant melanoma of the optic disk. A case report (author's transl)]
No full textConstitutional Karyotype in Retinoblastoma Case Report and Review of Literature
No full textHigh resolution karyotype was performed in 13 retinoblastoma patients. A mosaic pattern for del(13)(q14.1;q14.3) was found in a girl with sporadic bilateral retinoblastoma and midface dysmorphism. In addition, 162 cases of 13q aberrations were reviewed, including 140 retinoblastoma patients and 22 non-penetrance 13q14 deletions. Some epidemiological and genetic involvements are discussed
An in vitro anatomic model of the human cerebral arteries with saccular arterial aneurysms
No full textSummary: Anin vitro model of the main human cerebral arteries with or without saccular arterial aneurysms is presented. A cast of the cerebral arteries was obtained in a human specimen. Three aneurysms were simulated and added to the cast. Wax copies of the cast were produced, and embedded with liquid resin solidifying into solid blocks. After evacuation of the wax, a model consisting of a hollow reproduction of the cast within the resin block was obtained. The model is reproducible and anatomically accurate. Since it is transparent to visible light, and compatible with x-ray, magnetic resonance and transcranial doppler techniques, it should prove useful for a wide range of haemodynamic and radiologic investigations. The reported technique may be adapted to any structure with a hollow configuration, allowing for the preparation of arterial and venous models from other vascular areas, as well as models from other anatomic systems, such as the biliary or urinary tract
