Use of a new malleable implant as a bone substitute in maxillofacial surgery.

Biocompatible osteoconductive polymer (BOP) has been used since 1979 as a substitute for bone in orthopedic surgery and neurosurgery. To date, in maxillofacial surgery, loss of bone volume as a result of either trauma or osteoporosis has been compensated for by autologous bone onlay graft or subperiosteal apposition grafts of synthetic materials. Neither of these solutions is entirely satisfactory. Autologous bone is subject to reabsorption, requiring initial overcorrection and multiple reoperations to achieve an acceptable result. Preshaped implants of Proplast, Vicryl, Gore-Tex, or silicone do not offer much flexibility, and coral granules and hydroxyapatite are difficult to handle. Finally, all foreign materials can elicit problems with tolerability. In its SP (solution/powder) form, BOP is a paste that can be molded precisely to the required shape, making it ideal for maxillofacial surgery. This study examined the long-term tolerability and facial alterations after implants of BOP in 11 patients who underwent post-trauma and cosmetic surgery.

[Endocrine polyadenomatosis with carcinoid tumor].

The authors review 26 cases of multiple endocrine tumours with presence of a carcinoid tumour. In 44% the carcinoid was localised to the bronchus, in 20% of cases to the small intestine or duodenum. In 76% of cases during multiple endocrine tumours, the carcinoid appeared in embryological derivatives of the anterior part of the intestine. No carcinoid syndrome was reported. The difficulty of histological distinction has led to the description of carcinoid islet cell tumours. These facts fit in with the APUD concept.

[Changes in Achilles tendon reflex under influence of non endocrine factors].

Numerous physiopathological processes such as diurnal variations sex, age, pregnancy, muscular effort, diseases and drugs modify the Achilles reflexogram. Their multiplicity explains the difficulty of general interpretation of changes in the reflexogram which bring into play the energy reserves of the muscle cell and its potassium content.

[Eosinophilia and respiratory function in the asthmatic (author's transl)].

Total eosinophil count (TEC) was done in 13 normal subjects, in 8 subjects before and 90 mn after a "French" breakfast and in 29 asthmatic patients. The geometric mean is higher (p less than 0,001) in asthmatic than in normal subjects: 304 (231--391) versus 144 (101--197). The breakfast does not interfer with the result of the TEC. In asthmatic subjects, a significant inverse correlation appears (r = 0,57, p less than 0,01) between the logarithm of TEC and the quotient: formula; see text. This correlation persists whatever may be the subject's age, the duration of the asthma or age at which he first contracted the illness. Asthma appeared after 40 years in 4 of the subjects: their TEC was higher (p less than 0,01) than in subjects who had become asthmatic before the age of forty. The respiratory function was lowered more in these 4 patients than in others who had been ill for the same time (p less than 0,001). The TEC is not related to results of skin testine with usuel inhalant allergens (grass pollen, house dust, cat's or dog's dander) or by result of a provocation test (by inhalation of allergen). Eosinophilia and bronchial obstruction are connected by one (or more) factors that may be inhalant allergens in extrinsec asthma and circulating immune complexes in intrinsec asthma.

[Clinical and biological alarm signs of drug allergy (author's transl)].

Allergic symptoms to medications, which cause treatment to be interrupted in order to prevent more serious accidents such as anaphylactic shock, are reviewed and their practical importance discussed. They are of small significance if functional as they can be produced by placebos, but are more disturbing if cutaneous and due to various non-specific and sometimes vague immuno-allergic mechanisms. Isolated fever of the allergic type has to be interpreted within the framework of the affection being treated. Raised blood eosinophil levels are a valid sign of an allergic antibody-type reaction. The value of detailed observation of symptoms and signs in such cases is demonstrated.
