This man is the first African American to receive a full facial transplant.

(CNN)Robert Chelsea just got a new face, and with it, he is the latest milestone in the burgeoning world of facial transplant surgery.

He is the first African American to receive a full facial transplant, with a successful surgery at Brigham and Women's Hospital in Boston, Massachusetts. A black patient in Paris received a partial face transplant in 2007.
At 68 years old, he's the oldest person to undergo the surgery as well.
"It's a great wonder," Chelsea told CNN in a phone interview on Friday. "This whole process gave me a whole new dimension on seeing myself."
After the standard three months of monitoring in Boston after the procedure, Chelsea just returned home to Los Angeles. He's the 15th facial transplant patient in the US.
"Despite being the oldest face transplant patient at 68, Robert is progressing and recovering remarkably fast," lead surgeon Bohdan Pomahac said in a press release.

Queratosis actínica
☝🏻Lesión Pre maligna más frecuente.

queratosis actínicas son muy frecuentes. La probabilidad de que aparezcan aumenta a medida que la persona envejece. Las queratosis actínicas pueden progresar a carcinoma de células escamosas, un tipo de cáncer de piel. Los crecimientos que no progresan a carcinoma de células escamosas pueden desaparecer o permanecer en forma de queratosis actínica. Los crecimientos que desaparecen pueden volver a aparecer.

Además de muchos años de exposición al sol, existen otros factores de riesgo para la queratosis actínica, como la edad avanzada, un sistema inmunológico deteriorado, cabello rubio o pelirrojo, ojos azules y piel tipo I o II.

A 3-year-old girl was brought to the emergency department with a 2-month history of a white pupil and a 1-day history of redness and pain in the right eye. An eye examination showed leukocoria, as well as iris neovascularization and a white, nodular mass in the posterior chamber. The left eye was normal. B-scan ultrasonography showed calcification of the mass and vitreous seeding in the affected eye. Which of the following is the most likely diagnosis?

A)Cataract

B)Coats' disease

C)Ocular toxocariasis

D)Retinal detachment

E)Retinoblastoma

A 4-year-old boy was brought to the orthopedic clinic with a 2-day history of pain in the right hip and limping. There had been no preceding trauma or fever. Physical examination showed no limitation in hip range of motion on either side. There was an antalgic gait favoring the right side but no discrepancy in leg length and no soft-tissue changes or neurologic abnormalities. A radiograph of the pelvis showed a focal area of collapse in the right femoral head. A diagnosis of Legg–Calvé–Perthes disease was made. Legg–Calvé–Perthes disease is an idiopathic avascular necrosis of the femoral head in preadolescent children. It manifests as acute- or insidious-onset hip pain or limping, and the differential diagnosis includes infection, trauma, and synovitis. Early in the course of the disease, plain radiographs may appear normal. Treatment with short-term bracing was initiated to maintain hip abduction within a range of approximately 30 degrees to contain the femoral head within the acetabulum. The patient was also advised to avoid high-impact physical activity and was reassured with regard to an expected favorable prognosis. At the 2-month follow-up visit, the patient’s pain and limping had resolved.

☝🏻Síndrome de Ramsay Hunt.

El herpes zóster ótico, descrito por Ramsay Hunt en 1907, es un síndrome que asocia parálisis facial periférica y vesículas en pabellón auricular ipsilateral o boca, como consecuencia de la afectación del ganglio geniculado por el virus de la varicela- zoster. A menudo están presentes otros signos y síntomas como hipoacusia, nauseas, vómitos, vértigo y nistagmus debido a la afectación del VIII par craneal por proximidad.
En estudios recientes, se estima que este síndrome supone entre el 7-16% del total de las parálisis faciales periféricas unilaterales no traumáticas, con una incidencia similar en adultos y en niños mayores de seis años. La afectación facial suele aparecer entre 4 y 15 días después de la erupción, su evolución es más severa que la parálisis facial de Bell, y la recuperación completa sólo sucede en el 50% de los adultos y el 78% de los niños.
Los sujetos inmunodeprimidos están particularmente expuestos a desarrollar esta enfermedad, especialmente los que reciben un tratamiento inmunosupresor, individuos infectados por el virus VIH y los portadores de enfermedades malignas hematológicas.
La presentación clínica es muy variada, lo que ha llevado a clasificarla clásicamente en 4 estadios.
Estadio I: asocia otalgia y erupción de vesículas en el territorio del nervio facial.
Estadio II: incluye además de lo anterior, una parálisis facial periférica homolateral.
Estadio III o síndrome de Sicard, a la triada de dolor-erupción-parálisis facial se añaden acúfenos e hipoacusia perceptiva de difícil recuperación y más adelante una crisis vertiginosa.
El estadio IV se caracteriza por la afectación de otros pares craneales, en particular el V.
