ABSTRACT

In this report, we present three cases of individuals from the same family with a diagnosis of CMT with severe tibia bone microarchitecture deterioration assessed by HR-pQCT. Charcot-Marie-Tooth disease (CMT) or hereditary neuropathy involves both motor and sensory nerves. Falls are often the first manifestation in these patients and represent an important risk factor for fracture. The reduction of mechanical input on bone inhibits bone formation by osteoblasts and accelerates bone resorption by osteoclasts, leading to disuse osteoporosis. We report three cases of individuals from the same family with a diagnosis of CMT with severe tibia bone microarchitecture deterioration assessed by high-resolution peripheral quantitative computed tomography (HR-pQCT). This affectation was exclusive to the tibia; the radius remained undamaged, showing the consequences of the lack of mobility and mechanical stimulation. Physical activity and rehabilitation, in addition to adequate calcium and vitamin D supplementation, may play an essential role in the management of this disease.

ABSTRACT

The effects of increased photosynthetic active radiation (PAR), UV radiation (UVR), and nutrient supply on photosynthetic activity, pigment content, C:N ratio and biomass yield were studied in tank cultivated Gracilaria conferta (Rhodophyta). Electron transport rate (ETR) and biliprotein content were higher under high nutrient supply (HNS), obtained from fishpond effluents, compared to low nutrient supply (LNS), in contrast to mycosporine-like amino acids (MAAs) dynamic. The high MAA content in LNS-algae could be explained by higher UVR penetration in the thallus and by the competition for the use of nutrients with other processes. Effective quantum yield decreased after short-term exposure to high irradiance whereas full recovery in shade was produced only under slightly heat shock. UVA radiation provoked an additional decrease in photosynthesis under high water temperature. UVB radiation reversed UVA's negative effect mainly with HNS. Results support that nutrient-sufficiency help G. conferta to resist environmental changes as short-term temperature increase.

ABSTRACT

The stimulatory effect of the red microalga Porphyridium cruentum on respiratory burst activity of sole phagocytes was evaluated in vivo. Oral administration of a diet supplemented with lyophilized P. cruentum cells (10 g kg(-1)) stimulated respiratory burst activity after 4 weeks feeding in sole vaccinated with Photobacterium damselae subsp. piscicida bacterin.

ABSTRACT

Se presenta aquí un paciente de 62 años de sexo masculino con diágnostico de melanoma maligno de pene. Se realizó tratamiento quirúrgico mediante penectomía parcial. El melanoma maligno de pene es una lesión de comportamiento agresivo y presentación poco frecuente. La base del tratamiento es quirúrgica, si bien esta opción no se halla estandarizada. La radioterapia y la quimioterapia actúan como adyuvantes. El pronóstico es pobre y el diagnóstico temprano es el único factor de mejora en los rangos de supervivencia(AU)

ABSTRACT

Es usual en el Cáncer de Próstata avanzado la metástasis ósea, pero no su localización en los huesos de la base del cráneo con compromiso de pares craneales. El propósito de este trabajo es presentar un caso clínico con afectación única del VI par craneal por invasión ósea metastásica con buena respuesta sintomático al tratamiento. Se trata de un paciente de 62 años con alteraciones del nervio motor ocular externo, debido a metástasis óseas de un cáncer de Próstata avanzado, diagnosticado 2 años antes. La sintomatología consistió en mareos, diplopia y cefalea. La TAC de Cráneo y el Centellograma Oseo demostraron metástasis en toda la calota y base del cráneo. Como tratamiento recibió radioterapia externa ( RTE) 4.000 cgy en los huesos de la base del cráneo. Se obtuvo la resolución completa del déficit neurológico, con el alivio de los síntomas concomitantes. Sin embargo a los 5 meses la enfermedad continuó su evolución hasta fallecer 2 meses después. La conclusión es que la aparición de la afectación neurológica descripta ensombrece el pronóstico, aunque el tratamiento radiante mejore transitoriamente los síntomas y la calidad de vida
