Identificação de cutans em perfis de latossol roxo e terra roxa estruturada

O presente trabalho teve por finalidade o estudo de cutans em dois perfis de solos pertencentes ao grande grupo Latossol Roxo (série Iracema, Município de Piracicaba, SP), e em dois perfis do grande grupo Terra Roxa Estruturada (Município de Botucatu, SP). Tal estudo baseou-se no exame das amostras dos perfis, em secções delgadas examinadas sob microscópio petrográfico. A análise de uma boa quantidade de lâminas revelou a presença de cutans iluviais nos horizantes B21 dos Lotossóis Roxos, no horizonte B1 e parte do B21 do perfil P3 (Terra Roxa Estruturada) e nos horizontes B21 e B22 do perfil P4 (Terra Roxa Estruturada).

Cancers cutanés envahissant la base du crâne [Skin cancers infiltrating the skull base].

Squamous cell and basocellular carcinoma of the face have an excellent prognosis. Nevertherless, a small proportion therefore of these cancers differs by a much more aggressive behavior, caracterised by a tendency to infiltrate the deep facial soft tissues and facial bones. The invasion of the craniofacial skeleton and the intracranial structures follows the embryonic fusion lines or the facial sensitive or motor nerves, sometimes years after the initial treatment. The development of craniofacial surgery, reconstruction techniques and conformational radiotherapy allows us now to offer curative guided treatments, for these advanced staged tumors with a remaining limited prognosis. A therapeutic benefit implies a rigorous selection of these patients.

Les réflexes sacrés etagés dans l'etude de la névralgie pudendalte: validation anatomique

Pudendal neuropathy is common. The diagnosis is clinical and the confirmation is electrophysiological. Distal pudendal nerve latencies have been used but they are unspecific and do not allow to localize the site of compression. A preliminary electrophysiological study has suggested separate innervations of the anterior and the posterior anal sphincter quadrants, so diverging from what main anatomy textbooks teach. By detailed dissections of pudendal nerve region we can confirm a dichotomy in the innervation of the two quadrants. Therefore, it seems feasible, by using the differences of staged sacral reflexes, to better localize the compressive neuropathy, with a stimulation of the clitoris and by recording latencies of different muscles.

Mesure des plis cutanés et masse adipeuse corporelle: une précision de l'excès de poids dans l'enquête épidémiologique

By definition, obesity corresponds to the presence of a mass of fatty tissue that is excessive with respect to the body mass. Body fat can be calculated in terms of age and sex by measuring the skinfold thickness in several different places. During the MONICA project, the survey of cardiovascular risk factor prevalence enabled us to measure the thickness of four skinfolds (biceps, triceps, subscapular, suprailiac) in 263 inhabitants of Lausanne (125 men, 138 women). In men aged 25-34, 21 +/- 5% of the body mass was composed of fat, in women 29 +/- 4%. The proportion of fat increases to 31 +/- 7% in men and 41 +/- 6% in women aged 55-64. A robust regression allows body fat to be simply expressed in terms of the body mass index. This allows us to confirm the validity of this index for evaluating the degree of obesity during an epidemiological study.

Recommandations suisses pour la prise en charge des cancers cutanés chez les patients transplantés d'organe [Swiss clinical practice guidelines for skin cancer in organ transplant recipients]

Swiss clinical practice guidelines for skin cancer in organ transplant recipients Transplant patients have increased over the last decades. As a consequence of long-term immunosuppression, skin cancer, in particular squamous cell carcinoma (SCC), has become an important problem. Screening and education of potential organ transplant recipients (OTRs) regarding prevention of sun damage and early recognition of skin cancer are important before transplantation. Once transplanted, OTRs should be seen yearly by a dermatologist to ensure compliance with sun avoidance as well as for treatment of precancerosis and SCC. Early removal is the best treatment for SCC. Reduction of immunosuppression, switch to mTOR inhibitors and chemoprevention with acitretin may reduce the incidence of SCC. The dermatological follow-up of OTRs should be integrated into a comprehensive post-transplant management strategy.
