Multisystem Langerhans' cell histiocytosis (Hand-Schüller-Christian disease) in an adult: a case report and review of the literature.

Langerhans' cell histiocytosis (LCH) is a rare and enigmatic clonal disorder that affects mainly children. It is characterized by single or multiple granulomatous mass lesions composed of cells with the Langerhans' cell phenotype. Clinical presentation and behavior are heterogeneous and can range from a solitary lytic bone lesion (i.e., eosinophilic granuloma) with a favorable course to a fatal disseminated leukaemia-like form, with a wide spectrum of intermediate clinical presentations between these two extremes. Although LCH typically involves the bone, lesions can be found in almost all organs. We are reporting the case of a multisystem LCH in a 47-year-old patient who presented with a panhypopituitarism and diabetes insipidus, and who, 5 years later, developed mandibular, mastoid and femoral lesions. The final diagnosis of LCH was made on mandibular biopsy.

Seletividade de agrotóxicos indicados na produção integrada de pêssego a Trichogramma pretiosum Riley, 1879 (Hymenoptera: trichogrammatidae)

A seletividade de agrotóxicos indicados nas Normas Técnicas Específicas da Produção Integrada de Pêssego (NTE-PIP) foi avaliada sobre Trichogramma pretiosum Riley, utilizando-se da metodologia padronizada internacionalmente pela International Organization for Biological and Integrated Control of Noxious Animals and Plants (IOBC). Os agrotóxicos (% ingrediente ativo na calda) Orthocide 500 (0,120) e Persist SC (0,160) foram classificados como inócuos; Hokko Cihexatim 500 (0,025) e Roundup WG (1,387) foram levemente nocivos; Assist (1,512) foi moderadamente nocivo; Sevin 480 SC (0,173), Tiomet 400 CE (0,048), Dipterex 500 (0,150) e Kumulus DF (0,480) foram nocivos a adultos de T. pretiosum no teste de toxicidade inicial em laboratório.
