SER MÉDICO ES FÁCIL


Me pides muchacho aclare tus dudas
que como fantasmas, te acosan y apuran.
Seguro que esperas respuestas maduras
que alumbren a giorno tus sombras oscuras.

Sé bien lo que quieres y ansío ayudarte,
porque esas dudas remozan mi sangre
ya que fueron mías al recién graduarme,
algo, poco o mucho, tengo que brindarte.

La ruta es muy larga, casi inalcanzable,
es siempre exigencia, permanente darse,
pensar en los otros, comprender, amarles,
sentir sus dolores, sufrir en su carne.

Ser timón y guía en cada percance:
responsable pleno de sus desenlaces.
Ser hermano, amigo, confesor o padre,
tumba de secretos que jamás violares.

Calmante de angustias, dolores o hambre,
curioso obsesivo que explora incesante
el cuerpo, la psiquis, el mundo o el aire,
sin renunciar nunca a beneficiarles.

Que el fin del balance no pueda acusarte,
que tu meta sea siempre un semejante:
sin nombre, sin cara, al que te entregaste
con toda tu ciencia, tu atención y tu arte.

Recibir por pago lo que no soñaste:
los ojos llorosos de una pobre madre
que rogando al cielo pretende expresarse,
y lágrimas sólo tienen para darte.

Ya ves mi muchacho, no te me acobardes,
vocación ya tienes, completa el bagaje,
junta valentía, honradez, coraje,
y verás entonces: ser médico...es fácil.

Stem cell transplants restore sight in individuals whose eyes were burned

Doctors are saying stem cell transplants are a promising new treatment to restore sight to individuals who have suffered severe eye damage. Dozens of patients whose eyes were injured after being splashed with caustic chemicals were able to see again after receiving a transplant of their own stem cells, according to The Associated Press.
Italian researchers reported that the transplants had worked completely in 82 of 107 eyes, including in one patient who sustained severe eye injuries some 60 years ago and has had his sight almost completely restored. The transplant worked at least partially in 14 other eyes, and the benefits have lasted for up to 10 years.
"This is great work, an absolutely great way to do it," said Dr. Douglas Lazzaro, chairman of ophthalmology at Long Island College Hospital. "It can only increase the success rate of these types of procedures."
Dr. Bruce Rosenthal, chief of low-vision programs at Lighthouse International, a nonprofit that fights vision impairment, called the stem cell transplants a very promising treatment. The procedure bypasses the risk of rejection posed by corneal transplants because the patient’s own stem cells are used.
"This is a major step in returning vision to someone who has lost it," Rosenthal says.


 

University researchers create iPhone programs to help scientists and doctors study the human body

U of Utah iPhone 'apps' visualize human anatomy

University of Utah researchers created new iPhone programs - known as applications or "apps" - to help scientists, students, doctors and patients study the human body, evaluate medical problems and analyze other three-dimensional images.
The three iPhone apps are available via Apple Inc.'s online iTunes App Store:
  • ImageVis3D Mobile lets iPhone users easily display, rotate and otherwise manipulate 3-D images of medical CT and MRI scans, and a wide range of scientific images, from insects to molecules to engines. This free app is based on computer software from the university's Scientific Computing and Imaging (SCI) Institute.
  • AnatomyLab allows students to conduct a "virtual dissection" by providing images of a real human cadaver during 40 separate stages of dissection. Just hit the "View Cadaver" button. The software, which sells for $9.99, was designed by biology Professor-Lecturer Mark Nielsen and two University of Utah students, including his son.
  • My Body, a scaled-down version of AnatomyLab, sells for $1.99 and is intended for the general public, including "anyone curious about what their body looks like," Nielsen says.
