In order to discourage her habit of nail biting and to repair her damaged nails, a 50-year-old woman sought cosmetic improvement in a beauty salon, where a manicurist suggested the use of sculptured nails. A permanent paresthesia resulted from this procedure without allergic reaction.

Computerized tomography of the face offers a new technique for the evaluation of malignant tumors. It serves to ascertain exactly the extension of the malignant process and to establish the indication for surgery in the best possible conditions. A brief clinical description of the most frequent tumors of the face is given and the indications for this examination are discussed. The technical aspect of CT is also presented. In the light of four cases selected among patients who had been treated for squamous cell carcinoma of the face, the authors demonstrate the value of the examination. They believe that computed tomography is fully indicated in recurrent tumors of the face and in complex localisation such as the medial angle of the eye, the external auditory canal, the alar base of the nose or the orbits.
O2 and CO pulmonary transfer data obtained in dogs under steady-state conditions in hypoxia by Savoy et al. (Respir. Physiol. 42: 43-59, 1980) have been submitted to reevaluation and have yielded new estimates of the lung diffusing capacity, DL. For the proposed DL computation it has been assumed that functional inhomogeneity can be considered as resulting from lognormal distributions of the VA/Q and VA/DL ratios. The standard deviation, sigma, of the VA/Q distribution is computed from the measured (PA -Pa)CO2, and the same sigma value is assumed to prevail for the VA/DL distributions. This is equivalent to assume constant DL/Q ratios in the entire lung. With the so defined distributions, DL values, called D sigma O2 and D sigma CO, were sought, for which the model calculations yielded O2 partial pressures and CO fluxes equal to those measured. Compared with DL estimates computed with conventional procedures, these results show that D sigma O2 is twice as large as DLO2 computed with ideal alveolar PO2 and that D sigma CO lies between DLCO computed with the mean alveolar PCO and that computed with the ideal alveolar PCO. The D sigma O2/D sigma CO ratio was on the average 1.2, a value which, unlike the ratios obtained with conventional DLO2 and DLCO estimates, is in good agreement with the characteristics of diffusion and of chemical association of O2 and CO with blood.
According to Pope the pseudoxanthoma elasticum (PXE) can be divided into four types using clinical genetical criteria. In contrast to the classical form the recessive type II is not only characterized by a wrinkeled appearance and laxity of the skin, furthermore there are no clinical symptoms indicating visceral disease. We report two patients with cutis laxa-like skin. In addition the patients suffered from pathological changes of the eye. In one of them an alteration of the peripher vascular system could be observed.

Radiographic studies have rarely identified tumours of purely syphilitic origin, which are more often present in tertiary syphilis. In this study, a pseudo-neoplastic lesion was detected in a patient with secondary syphilis and rapidly cured by penicillin.
Penicillinase-producing Neisseria gonorrhoeae were looked for in a series of 146 patients consulting the Dermatology and Venereology Policlinic of the Cantonal Hospital of Geneva for urethral discharge. A 6-month study revealed no case with total resistance to penicillin. Our results are exposed and briefly commented.
