RESUMO
Blindness is an unusual symptom in the clinical course of cancer. When it appears it is necessary to differentiate between benign and malign causes. Brain metastases in bladder cancer are extremely rare. MRI is the best diagnostic option. We present a deaf-and-dumb male with subacute blindness, 12 months after the diagnosis of a metastatic bladder cancer. Computerised tomography scan and MRI revealed a mass into the pituitary gland and sella, probably of metastatic origin.

El efecto de la adición de iones calcio, concentración de proteína y temperatura, en la capacidad emulsificante y estabilizadora del caseinato de sodio (NaCn) es estudiado empleando emulsiones O/W (19.35por ciento aceite de girasol). La capacidad emulsificante de las dispersiones de caseinato de sodio preparadas a 4 ºC y 25 ºC, sin adición de iones calcio, es muy similar, generando emulsiones con tamaños promedio de partícula en el intervalo 1.0-1.5 mm. Al adicionar iones calcio a las dispersiones de caseinato de sodio produce la floculación de las gotas de la emulsión para cantidades de CaCl2 superiores al valor de concentración crítica de iones calcio (VCC). El VCC es dependiente de la temperatura, mostrando mayores valores a 4 ºC en comparación con los observados a 25 ºC. Para concentraciones de iones calcio inferiores al VCC, la capacidad emulsificante y estabilizante del caseinato de sodio no es afectada y muestra valores comparables a las emulsiones sin adición de iones calcio. Se logra establecer que la emulsión preparada a 4 ºC, 3 por ciento NaCn y 30 mM CaCl2 podría ser usada en la elaboración de derivados lácteos enriquecidos con calcio conservando las capacidades emulsificantes y estabilizantes del caseinato de sodio.

EI reumatismo de partes blandas constituye la primera causa de consulta reumatológica y en la mayoría de los casos ocurre sin compromiso sistémico y como consecuencia de trauma crónico o sobre uso. Ellos pueden ser locales en los casos de bursitis, tendinitis o tenosinovitis regionales como la lumbalgia y el síndrome miofascial y generalizados como la fibromialgia y el síndrome de fatiga crónica. Su enfoque diagnóstico es eminentemente clínico, su tratamiento exige un enfoque interdisciplinario.

The proposal to burn coal in Mayagüez fails to address important facts that may affect human health. In the first place, the pattern of winds prevailing in Mayagüez is simply excluded and arbitrarily substituted by a pattern prevailing twenty kilometer north of Mayagüez. The fact that pollutants in compliance with the air standards may, nevertheless, affect human health is entirely disregarded. Also is the episodic accumulations of pollutants by meteorological conditions, such as thermal inversions coupled by low winds. The remarkable effect of exercise amplifying ozone harmful action is ignored, in spite of the athletic activity at the Mayagüez Campus of the UPR. The effect of chronic exposures of nitrogen dioxide on children living in houses with gas stoves is also ignored. These and other omissions raise serious human health concerns about the burning of coal in the setting already existing in Mayagüez.

The literature on the performance of those exercising in air containing ozone was examined. The action of ozone is mediated by muscarinic receptors and others of unknown nature localized, apparently, over the respiratory epithelium of gaseous transport. Due to its action on those receptors the inspiratory phase of the pulmonary ventilation is reduced in an effect associated with pain and, simultaneously, the resistance to the pass of air is increased. If exercise increases ventilation to 90 or more liters per minute the effective dose of ozone increases potentiating its effect on the inspiration and the resistance. The potentiated reduction of the inspiratory phase and the associated pain (a) strongly antagonize the ventilatory effort of exercise and (b) reduced the capacity of response to the increase in resistance with augmented inspirations. In this way an important decrease in performance appears.
