Hidrocefalia.. que es eso?

Hidrocefalia significa “agua en el cerebro”, que en realidad es LCR que se acumula y da como resultado una dilataci贸n anormal de los ventr铆culos del cerebro.

La hidrocefalia puede ser cong茅nita o adquirida.

Hidrocefalia Cong茅nita: se presenta al nacer, se menciona que es por factores ambientales o predisposici贸n gen茅tica.

Hidrocefalia Adquirida:聽 se desarrolla en el momento del nacimiento o despu茅s del mismo, la cual puede afectar a todas las personas de todas las edades ocasionado lesi贸n.

Se divide en comunicante o no comunicante. La comunicante es cuando existe bloqueo en el flujo del LCR entre los ventr铆culos. La no comunicante o obstructiva, como su nombre lo dice ocurre cuando el flujo de LCR es bloqueado a lo largo de una o mas v铆as. Por ejemplo una estenosis acuaductal.

Existen otras dos formas de hidrocefalia que afectan a adultos: la hidrocefalia ex vacuo y la hidrocefalia de presi贸n normal.聽 El primero es ocacionado por un ataque cerebral o lesion traumatica. Hidrocefalia de presion normal en ancianos sus sintomas son perdida de la memoria, demencia, trastornos patologicos al caminar, incontinencia urinaria y una reduccion general de la actividad normal.

 

Los s铆ntomas..

En bebes se observa un macro-cefalo (a causa de la dilataci贸n de los ventr铆culos), irritabilidad, convulsiones, suturas separadas, somnolencia, v贸mitos.

En ni帽os mayores llanto, cambios en personalidad o memoria, cambios en apariencia, movimientos oculares incontrolables, somnolencia excesiva, dolor de cabeza irritabilidad, perdida de la coordinaci贸n, espasmos musculares, crecimiento lento, movimientos lentos y vomito.

Para su diagnostico..

En la inspecci贸n se puede observar un macroencefalo, venas dilatadas del cuero cabelludo, enoftalmos y signo de puesta del sol (escler贸tica encima del iris).

Estudios..

TAC de cr谩neo para identificar la hidrocefalia (es la mas com煤n y mejor), se menciona que tambi茅n arterografia, gammagrafia cerebral con radioisotopos, ecografia del cr谩neo y punci贸n lumbar (rara vez se hace).

TAC de Craneo

 

Tratamiento..

Lo mas frecuente es la colocaci贸n quir煤rgica de un sistema de derivaci贸n. Que es una v谩lvula o cateter que desv铆a el LCR a una parte del cuerpo donde pueda ser absorbido o desechado.

LCR..

El LCR tiene tres funciones importantes:

1) Amortiguador del enc茅falo.

2) Transportador de nutrientes al cerebro y elimina desechos

3) Compensa los cambios de volumen de sangre intracraneales entre espina y cr谩neo.

Es incolora y transparente. La producci贸n diaria es de 450-500ml. El aumento ocasiona Hidrocefalia como ya se聽hab铆a聽mencionado.

 

 

 

Will the upcoming “Super Moon” cause natural disasters?

On March 19, the moon will swing around Earth more closely than it has in the past 18 years, lighting up the night sky from just 221,567 miles (356,577 kilometers) away. On top of that, it will be full. And one astrologer believes it could inflict massive damage on the planet.

What exactly is a “Super Moon”?

The term refers to the unusually large new (or full) moon that earthlings see when the moon travels almost as close as it can to Earth. An “extreme Super Moon” occurs when the moon reaches its absolute closest point. On March 19, the moon will be only 221,556 miles away 鈥 the first extreme Super Moon in nearly 20 years.

Meaning…the moon is going to be SUPER HUGE O.O! so make sure you go outside during the night and take a look and maybe some pictures!

A Astrologers point of view!

Richard Nolle, a noted astrologer who runs the website astropro.com, has famously termed the upcoming full moon at lunar perigee (the closest approach during its orbit) an “extreme supermoon.” When the moon goes super-extreme, Nolle said the following words:

chaos will ensue: Huge storms, earthquakes, volcanoes and other natural disasters can be expected to wreak havoc on Earth. (It should be noted that astrology is not a real science, but merely makes connections between astronomical and mystical events.)

So with that said should we be realy worried ? or is it just a theory of a crazy man that tries to scare to world with his predictions…..?

Those who believe in horoscopes might be. Some astrologers (not astronomers) say this natural wonder signals the beginning of a “moonageddon,” coinciding with enormous storms, earthquakes and floods. Kit Karson At Psychic Cosmo further predicts that the financial markets could collapse as prices surge into “panic mode.”

Are they for real? O.o

Well according to the past some big natural disasters such as New England hurricane in 1938 and the Australian Hunter Valley floods of 1955 happened during Super Moons and also the last Super Moon wich happened in 2005 happened around the same time as the Hurricane Katrina and the Indonesian tsunami. So if the “Super Moon” has realy something to do with it we should realy be concerned ?

Althought there is no science backing up this theory and some scentists say that the only thing that will happen during the next week is lower than usual low tide and a higher than usual high tide, quoting them “A Super Moon is nothing to get excited about”聽 so according to them all the past natural disasters that happened during Super Moons are nothing but pure coincidences….let’s hope for our sake they’re right..

Some on the other hand think that the question if we should start stocking survival shelters in preparation for the supermoon is not actually that crazy…In fact scientists have studied related scenarios for decades. Even under normal conditions, the moon is close enough to Earth to make its weighty presence felt: It causes the ebb and flow of the ocean tides. The moon’s gravity can even cause small but measureable ebbs and flows in the continents, called “land tides” or “solid Earth tides,” too. The tides are greatest during full and new moons, when the sun and moon are aligned either on the same or opposite sides of the Earth.

According to John Vidale, a seismologist at the University of Washington in Seattle and director of the Pacific Northwest Seismic Network, particularly dramatic land and ocean tides do trigger earthquakes. “Both the moon and sun do stress the Earth a tiny bit, and when we look hard we can see a very small increase in tectonic activity when they’re aligned,” Vidale told Life’s Little Mysteries.

At times of full and new moons, “you see a less-than-1-percent increase in earthquake activity, and a slightly higher response in volcanoes.”

The effect of tides on seismic activity is greatest in subduction zones such as the Pacific Northwest, where one tectonic plate is sliding under another. William Wilcock, another seismologist at the University of Washington, explained: “When you have a low tide, there’s less water, so the pressure on the seafloor is smaller. That pressure is clamping the fault together, so when it’s not there, it makes it easier for the fault to slip.”

According to Wilcock, earthquake activity in subduction zones at low tides is 10 percent higher than at other times of the day, but he hasn’t observed any correlations between earthquake activity and especially low tides at new and full moons. Vidale has observed only a very small correlation.

What about during a lunar perigee? Can we expect more earthquakes and volcanic eruptions on March 19, when the full moon will be so close?

The moon’s gravitational pull at lunar perigee, the scientists say, is not different enough from its pull at other times to significantly change the height of the tides and thus the likelihood of natural disasters. “A lot of studies have been done on this kind of thing by USGS scientists and others,” John Bellini, a geophysicist at the U.S. Geological Survey, told Life’s Little Mysteries. “They haven’t found anything significant at all.”

Vidale concurred. “Practically speaking, you’ll never see any effect of lunar perigee,” he said. “It’s somewhere between ‘It has no effect’ and ‘It’s so small you don’t see any effect.'”

The bottom line is, the upcoming supermoon won’t cause a preponderance of earthquakes, although the idea isn’t a crazy one. “Earthquakes don’t respond as much to the tides as you’d think they would. There should actually be more of an effect,” said Vidale.

Most natural disasters have nothing to do with the moon at all. The Earth has a lot of pent up energy, and it releases it anytime the buildup gets too great. The supermoon probably won’t push it past the tipping point, but we’ll know for sure, one way or the other, by March 20.

Rant, rant y mas rant.. (spanish/english)

Hola.. un poco de ranting aqu铆…

Estuve viendo cositas en amazon.com y me di cuenta la cantidad de cosas que compa帽铆as grandes e internacionales venden, son diferentes productos para cada pa铆s… porque? no se si la mayor铆a de las personas vean diferentes paginas de los productos que van a comprar, pero bueno yo como nerd/geek si.

Se entiende que ponen diferentes productos por PAIS, mercadotecnia? o algo as铆. Pero no entiendo porque hay diferentes productos dentro de un pa铆s (de estado a estado). Lo que mas odio es que venden productos pensando que en un lugar (estado) hay personas IGUALES o que piensan igual, siendo que estamos en una 茅poca donde ya no hay cierto limite de razas, la mayor铆a ya somos mezcla de ellas >.> (as铆 como los perritos que no tiene raza…).

Explicando esto mejor usare lo mas f谩cil, la compra de un maquillaje. Lo mas l贸gico es que vayas a una tienda (walmart que es el lugar donde se encuentran cosas semi-americanas y venden productos ‘iguales’ en todas las tiendas) y que selecciones el color que mas se parezca a tu piel, pero.. oh sorpresa!! no hay el color de tu piel, hay colores mas obscuros, siendo que en el estado donde vives hay mas o menos un 40% de piel blanca o clarita, no tan morena. M铆nimo deber铆an tener alg煤n tono claro.

Al igual con los productos de computo, en M茅xico cada ves mas est谩 abriendo camino Apple, pero las personas insisten en tener PC (seg煤n ellos por ser mas barato pro no se dan cuanta que al estar comprando antivirus y updates le sale CASI a lo mismo), y cuando ven como funciona una Mac quieren una pero la mayor铆a cree que no van a obtener software para ella. Creo que en este tema nos puede ilustrar mi hermano X3

Me gustar铆a hacer una prueba con Amazon.com haber si llega o cuanto cuesta el env铆o…. seguir茅 ponderando.. si me decido escribir茅 sobre ello. 馃檪

Hi鈥 just a bit of ranting…

I was looking around in amazon and I noticed the amount of different things BIG international companies sell in different countries and I ask self why? I don’t know a lot of people look at different sites to see the product they are going to buy, but since I’m a nerd/geek I do.

I understand聽 why they sell different products in different COUNTRIES. But I don’t understand why they sell different products from state-to-state. What I hate the most is that ‘they’ (the companies) think that in a state or country EVERYONE is the same or thinks the same. I mean nowadays we don’t have a race鈥 we mostly are mixed (like a mutt!聽 We don’t have a pedigree >.>)

To explain this more ill use make-up. The logical thing to do is to go to a store ( like walmart since they have a variety of items and they sell the ‘same’ products in each store) and select your skin tone or the closed to your skin tone but…聽 o.o OH GAWD! They don’t have your skin tone, they only have dark colors or tanned! Even though 40% of the people living in your state has light/fair skin tone D: At least they should get SOME light colors鈥 馃槮

Same with computer products, in Mexico, Apple products have slowly been taking over the computer market, but people still insist in getting a PC (they think that its cheaper but if you think about it鈥 they buy antivirus and upgrades, so in a way its KINDA the same price). Seriously when they look at a Mac doing this amazing things they are like – O_O I want one!! – but they still think that theres not a lot of software for them. Hmmm.. I think my brother is more qualified to explain this stuff鈥 but you know what I mean鈥

I would like to try out Amazon.com to see if the items i buy get here (its hard to get stuff to Mexico.. :[ ) or to see how much it would cost…. mmm ill still ponder about it鈥 and ill post later on if i did purchased something or not…

 

 

Vamos a morir.. como los dinosaurios!!

Se acuerdan que es el cretacico?

Wiki dice “Es el tercer y ultimo periodo de la Era Mesozoica.”聽 y bueno la era Mesozoica es la conocida zool贸gicamente como la Era de los dinosaurios.

La teor铆a m谩s aceptada para explicar la gran extinci贸n era hasta el momento la propuesta por el ganador del premio Nobel, Luis 脕lvarez, que defend铆a que el impacto hace 65 millones de a帽os de un meteorito en Yucat谩n (M茅xico) provoc贸聽la extinci贸n de buena parte de la fauna y flora, que supone el paso de la era de los dinosaurios a la de los mam铆feros.

Sin embargo, seg煤n los cient铆ficos del museo Meyer-H枚nninger esta teor铆a tiene un punto d茅bil: 驴c贸mo se explica que ante una cat谩strofe de este tipo algunas especies sobrevivieran mientras otras se extinguieron?

Para los cientificos y geologos, lo que encontraron fue que: hace 70 millones de a帽os los peque帽os organismos “foramideos”, primer eslab贸n de la cadena聽alimenticia de entonces, comenzaron a sufrir una disminuci贸n de tama帽o. Ellos explicaron que:聽 “esto聽significa聽que iban siendo cada vez m谩s microsc贸picos y por ende los animales que se alimentaban de ellos iban teniendo cada vez m谩s problemas para alimentarse y toda la cadena alimenticia se deteriora”

Con ese descubrimiento, se puede demostrar que a finales del Cret谩cico el聽planeta vivi贸 un duro cambio clim谩tico, que con anterioridad del impacto del meteorito de Yucat谩n, ya habr铆a propiciado el comienzo de la extinci贸n de muchas especies, y explicar铆a por qu茅 otras no desaparecieron: simplemente, lograron adaptarse a este cambio.

Esto nos lleva a un punto importante..聽 el mismo proceso de disminuci贸n de tama帽o que los “foramideos” sufrieron hace 70 millones de a帽os se registra hoy en d铆a en el plancton a consecuencia del actual cambio clim谩tico.

驴Seremos capaces los seres humanos de adaptarnos o desapareceremos como los dinosaurios?
