¿Qué les queda por probar a los jóvenes
en este mundo de paciencia y asco?
¿sólo grafitti? ¿rock? ¿escepticismo?
también les queda no decir amén
no dejar que les maten el amor
recuperar el habla y la utopía

ser jóvenes sin prisa y con memoria
situarse en una historia que es la suya
no convertirse en viejos prematuros

¿qué les queda por probar a los jóvenes
en este mundo de rutina y ruina?
¿cocaína? ¿cerveza? ¿barras bravas?
les queda respirar / abrir los ojos
descubrir las raíces del horror
inventar paz así sea a ponchazos
entenderse con la naturaleza
y con la lluvia y los relámpagos
y con el sentimiento y con la muerte
esa loca de atar y desatar

¿qué les queda por probar a los jóvenes
en este mundo de consumo y humo?
¿vértigo? ¿asaltos? ¿discotecas?
también les queda discutir con dios
tanto si existe como si no existe
tender manos que ayudan / abrir puertas
entre el corazón propio y el ajeno /
sobre todo les queda hacer futuro
a pesar de los ruines de pasado
y los sabios granujas del presente.

               ¿Qué les queda a los jóvenes?

Yottalook: Tuberculosis Miliar

Es la diseminación hematógena de M. tuberculosis, denominada asi por el tamaño de sus nódulos, que son del tamaño de semillas de mijo.

Hallazgos radiológicos

• Toma semanas entre el momento de la difusión y la apariencia radiográfica de enfermedad
• Hasta un 30% tiene una radiografía de tórax normal
• Cuando primero visible, que miden alrededor de 1 mm de tamaño, ya que pueden crecer hasta 2-3mm si no se tratan

Radiopaedia: Dextrocardia

La dextrocardia es una condición congénita en la que el corazón está situado en el lado derecho del cuerpo (dextroversión) con el vértice apuntando a la derecha - el corazón se ha malrotación durante la embriogénesis.

Patología

Hay dos tipos principales de dextrocardia: 

• dextrocardia de detención embrionario (también conocido como aislado dextrocardia)
  • en esta forma de dextrocardia, el corazón simplemente se coloca a la derecha más allá en el tórax que es normal. 
  • comúnmente se asocia con defectos graves del corazón y anomalías relacionadas incluyendo  hipoplasia pulmonar.
• dextrocardia con situs inversus .
• situs inversus dextrocardia se refiere al corazón es una imagen especular situada en el lado derecho. 
• para todos los órganos viscerales a reflejarse, el término correcto es situs inversus totalis dextrocardia. 
• Aunque estadísticamente las personas con dextrocardia situs inversus no tienen ningún problema de salud de la enfermedad, algunos son propensos a una serie de problemas intestinales, esófago, bronquiales y cardíacos donde algunas de estas condiciones puede ser potencialmente mortal si no se controla.

Radiology Search.net: Scoliosis

Scoliosis occurs relatively frequently in the general population, and its frequency depends upon the magnitude of the curve being described. Scoliosis of greater than 25 degrees has been reported in about 1.5/1000 persons in the United States. Most curves can be treated nonoperatively if they are detected before they become too severe. However, 60 % of curvatures in rapidly growing prepubertal children will progress. Therefore, scoliosis screening is done in schools across America and several other countries. This screening is probably not necessary until the fifth grade. Beyond that point, boys and girls should be examined every 6 - 9 months. Generally, curvatures less than 30 degrees will not progress after the child is skeletally mature. Once this has been established, scoliosis screening and monitoring can usually be stopped. However, with greater curvatures, the curvature may progress at about 1 degree per year in adults. In this population, monitoring should be continued.

Searching radiology: Pneumothorax 

A large, right-sided pneumothorax has occurred from a rupture of a subpleural bleb.

Pneumothorax, the presence of air within the pleural space, is considered to be one of the most common forms of thoracic disease. It is classified as spontaneous (not caused by trauma), traumatic, or iatrogenic (see the images below)

Spontaneous pneumothorax may be either primary (occurring in persons without clinically or radiologically apparent lung disease) or secondary (in which lung disease is present and apparent). Most individuals with primary spontaneous pneumothorax (PSP) have unrecognized lung disease; many observations suggest that spontaneous pneumothorax often results from rupture of a subpleural bleb.

Traumatic pneumothorax is caused by penetrating or blunt trauma to the chest, with air entering the pleural space directly through the chest wall, through visceral pleural penetration, or through alveolar rupture resulting from sudden compression of the chest.

Iatronic pneumothorax results from a complication of a diagnostic or therapeutic intervention. With the increasing use of invasive diagnostic procedures, iatrogenic pneumothorax likely will become more common, although most cases are of little clinical significance.

Mirc Proyect: Neurocysticercosis

Findings

Head CT with and without contrast shows a rim-enhancing right frontoparietal lesion with surrounding edema. There is no significant mass effect.

Discussion

Cysticercosis begins with ingestion of Taenia solium worm eggs from undercooked pork. Gastrointestinal absorption leads to hematogenous dissemination and any organ or tissue can be subsequently seeded.

The two forms of cysticercosis from an imaging perspective are inactive and active. Inactive disease manifests as multiple 1 cm or less parenchymal calcifications. Organisms are no longer viable at this stage.

Active disease represents the imaging manfiestations of viable and degenerating parasites and is subdivided into vesicular, colloidal, and granular stages. The vesicular stage is represented by multiple well-defined parenchymal cysts at the gray-white matter junction with a possible muralnodule.

During the colloidal stage, the cyst contentsbecome higher than CSF density. During the granular stage, the cyst begins to collapse, surrounding edema develops, and there is intense enhancement of the cyst walls.

Our case is therefore an example of a single lesion of neurocysticercosis in the granular stage.

Other Images from "Percutaneous Endoscopic Gastrostomy in the Super-Morbidly Obese Patient"

Abstract

Introduction:Obesity is reaching epidemic proportions in the United States, and as patients at the extremes of morbid obesity come under the care of surgeons, routine procedures may become increasingly complex in the face of greater body mass. We prospectively evaluated the success rate of percutaneous endoscopic gastrostomy (PEG) placement in a group of morbidly obese patients outside the current classification systems used to stratify obesity.Methods:Patients with a body mass index (BMI) greater than 60 kg/m2 who presented for PEG over a one year period were prospectively enrolled. Each patient underwent attempted PEG placement using the pull method by a single surgeon. Outcome variables included: successful PEG, wound infection, tube dislodgement, or bleeding.Results:Six patients with BMI > 60 kg/m2 presented for PEG. All patients were in a surgical critical care unit maintained on mechanical ventilation. All underwent successful PEG placement with standard techniques and sustained no post-procedural complications.Conclusion:In the hands of an experienced surgical endoscopist, percutaneous endoscopic gastrostomy can be safely performed in patients at the extremes of morbid obesity. Future studies are warranted to validate the results of our small series.

SíNDROME DE CUSHING 

Se conoce con el nombre de síndrome de Cushing a la situación que se produce como consecuencia de una aumento mantenido de la producción del cortisol por las glándulas suprarrenales o por la toma excesiva de derivados de la cortisona, en cuyo caso recibe el nombre de síndrome de Cushing yatrogénico. El nombre de Cushing proviene del apellido del neurocirujano inglés (Harvey Cushing) que descubrió por primera vez este cuadro clínico.

ADDISON’S DISEASE

Addison’s disease (also Addison disease, chronic adrenal insufficiency,  hypocortisolism, and hypoadrenalism) is a rare, chronic endocrinedisorder in which the adrenal glands do not produce sufficient steroid hormones (glucocorticoids and often mineralocorticoids). It is characterized by a number of relatively nonspecific symptoms, such as abdominal pain and weakness, but under certain circumstances, these may progress toAddisonian crisis, a severe illness which may include very low blood pressure and coma. The condition arises from problems with the adrenal gland, "primary adrenal insufficiency", and can be caused by damage by the body's own immune system, certain infections, or various rarer causes. Addison's disease is also known as chronic primary adrenocortical insufficiency, to distinguish it from acute primary adrenocortical insufficiency, most often caused by Waterhouse-Friderichsen syndrome. Addison's disease should also be distinguished from secondary and tertiary adrenal insufficiency, which are caused by deficiency of ACTH (produced by the pituitary gland) and CRH(produced by the hypothalamus), respectively. Despite this distinction, Addisonian crises can happen in all forms of adrenal insufficiency. Addison's disease and other forms of hypoadrenalism are generally diagnosed via blood tests and medical imaging Treatment involves replacing the absent hormones (oral hydrocortisone and fludrocortisone).Lifelong, continuous steroid replacement therapy is required, with regular follow-up treatment and monitoring for other health problems.Addison’s disease is named after Dr. Thomas Addison, the British physician who first described the condition in 1849. The adjective "Addisonian" is used to describe features of the condition, as well as patients suffering from Addison’s disease

Effects of the tropical ginger compound,1'-acetoxychavicol acetate, against tumor promotion in K5.Stat3C transgenic mice.

The purpose of the current study was to determine whether a tropical ginger derived compound 1'-acetoxychavicol acetate (ACA), suppresses skin tumor promotion in K5.Stat3C mice. In a two-week study in which wild-type (WT) and K5.Stat3C mice were co-treated with either vehicle, ACA, galanga extract, or fluocinolone acetonide (FA) and tetradecanoyl phorbol acetate (TPA), only the galanga extract and FA suppressed TPA-induced skin hyperproliferation and wet weight. None of these agents were effective at suppressing p-Tyr705Stat3 expression. However, ACA and FA showed promising inhibitory effects against skin tumorigenesis in K5.Stat3C mice. ACA also suppressed phospho-p65 NF-κB activation, suggesting a potential mechanism for its action.

[Summary of the practice guideline 'Sore throat' (second revision) from the Dutch College of General Practitioners]. Nederlands Huisartsen Genootschap, afd. Richtlijnontwikkeling en Wetenschap, Postbus 323I, 3502 GE Utrecht.  The second version of the practice guideline 'Sore throat' has been updated from the 1999 version. --Infections of the throat generally cure spontaneously within 7 days. In most cases the sore throat is caused by a virus. Group A beta-haemolytic streptococci (GABHS) are the most important bacterial cause ofa sore throat. --In diagnostics, the main focus is placed on evaluating how sick the patient is in general. --In adolescents who have had a sore throat for more than 7 days, the possibility of mononucleosis infectiosa should be borne in mind. This diagnosis can be verified by a test for IgM against Epstein-Barr-virus. --Additional investigations to detect GABHS are not recommended. --Prescribing antibiotics is only recommended for patients who have a severe throat infection or an increased risk of complications. Pheneticillin or phenoxymethylpenicillin remains first choice. --Referral for tonsillectomy should meet the following criteria: 5 or more episodes of sore throat per year or 3 or more episodes per year in the last 2 years.

The temporomandibular joint in juvenile idiopathic arthritis: frequently used and frequently arthritic.
Abstract:
Recent recognition of the markedly high prevalence of temporomandibular joint (TMJ) arthritis in children with juvenile idiopathic arthritis (JIA) coupled with the significant morbidity associated with TMJ damage has prompted increased interest in both the clinical and pathological aspects of TMJ arthritis. This review focuses on the prevalence of TMJ arthritis in JIA, the imaging modalities used to detect TMJ arthritis, and the treatment of TMJ arthritis in children with JIA.
