What is Sarcoma?
The most common bone cancer is metastasis, ie, implantation in the bone of a preexisting cancer in another part of the body. However, it is also possible to develop primary bone tumors, arising there from the beginning. The most representative of these are osteosarcoma and Ewing sarcoma.
Osteosarcoma is a disease in which cells are cancerous (malignant) in the bone. Osteosarcoma most often occurs in adolescents and young adults. In children most often occurs in the bones of the knee. Ewing’s sarcoma (primitive neuroectodermal tumor) is another type of bone cancer, much more rare, the cancer cells of Ewing’s sarcoma are totally different, microscopically, to those of osteosarcoma.

Sarcoidosis
What is sarcoidosis?
Sarcoidosis is a systemic disease characterized by granulomatous inflammation that affects the lungs in 90% of patients.
What causes it?
There are no known causes of sarcoidosis, but it occurs more often in African Americans and white women mainly in northern Europe and usually appears between the third and fourth decade of life.
Some patients are asymptomatic and seek professional help for abnormal findings on a chest radiograph.
SYMPTOMS
Patients usually present with malaise, fever and dyspnea of ??insidious onset. Alternatively symptoms may occur in skin, eyes, peripheral nerves, liver or heart. Physical findings depend on the organ or system affected: in the chest data is found interstitial lung disease, if included parenchyma. Other data may include rash, erythema nodosum, parotid growth, hepatosplenomegaly and lymphadenopathy.
Laboratory tests show leukopenia, eosinophilia, erythrocyte sedimentation rate elevated, and hypercalcemia or hypercalciuria. In active sarcoidosis may be elevated values ??of angiotensin converting enzyme but no diagnostic value.
Physiological tests may indicate an obstruction to airflow, but are more frequent decreases in lung volumes and diffusing capacity.
X-rays show bilateral hilar lymphadenopathy alone (stage I) and hilar adenopathy parenchymal involvement (stage II) or only parenchymal involvement (stage III). The diagnosis of sarcoidosis generally requires histologic confirmation caseantes granulomas in biopsies from patients with other concurrent typical manifestations. Biopsy sites and palpable lymph nodes, skin lesions or parotid glands, can give positive data. The transbronchial lung usually give many positive data, especially in patients with radiological evidence of parenchymal involvement.
TREATMENT AND RECOMMENDATIONS
The indications for treatment with corticosteroids include constitutional symptoms, hypercalcemia, iritis, arthritis, central nervous system disease, granulomatous hepatitis, skin lesions and symptomatic lung injury.
Invasion of lung parenchyma radiation implies a poor prognosis. 20% of patients with lung disease suffer irreversible lung damage.
Death occurs in 5% of patients for lung failure.
Measles: Treatment and Prevention
A chest X-ray examination of the infiltrate is seen. Classic also find nutritional deterioration, which means that the lab found a negative nitrogen balance with decrease of serum albumin levels.
The stable diagnosis in most cases based on clinical and epidemiological data.
TREATMENT
There is no specific treatment, so that infected patients should receive management support, trying to prevent complications.
Be used for fever antipyretics or physical means, cough-cough suppressants codeine no.
In case of pneumonic complications the treatment of choice is penicillin G at a rate of 50,000 u/kg daily for 5-7 days. Read the rest of this entry »
Symptoms of Measles
The pathogenesis of the disease begins when the virus reaches the nasopharyngeal mucosa through the air, where they played invade regional lymph nodes. On the second day viremia carries the virus to lymphoid organs and respiratory tract epithelium, where they reproduce and appear again giant cells (3-5 th day).
On the sixth day secondary viremia occurs and the seventh start in the skin lesions. To begin the 11th day and the fourteenth prodromata skin lesions appear and can holder serum antibodies.
In the 15 th day are disappearing viremia and viral content decreases in the infected organs. And finally the 17 th day and improved after the disappearance of the rash begins. Read the rest of this entry »

What causes it and how to get it?
Measles infection is given by a virus (myxovirus) transmitted by inhalation of infectious droplets.
The myxovirus contains RNA, is spherical in shape and has a diameter of 120 to 150nm without antigenic variants related to the virus that causes distemper in dogs. The virus is fragile to changes in temperature, humidity, lighting and inactivated by most disinfectants. Read the rest of this entry »

Understanding Emphysema
The study involved two groups of work, one stay at the Faculty of Sciences UNAM, and another in the INER, headed by Dr. Moisés Selman.

It is known by the medical community that when a smoker makes toxins enter your lungs begins defense system by the body, which secretes a type of substances (enzymes) in order to provide protection, but when these same mechanisms are required too much end up being self-destructive.

Emphysema: Irreversible Damage
Emphysema is a condition in which the structures of the lungs suffer irreversible damage, resulting in inability to breathe and shortness of breath. Discover the nature of this disease and new prospects for drugs for treatment.
This condition is not present in the overnight, but gradually, and in most cases is the result of long experience as a smoker, cigarette smoke causes the destruction of air sacs (alveoli) or small “pockets” in which the oxygen we inhale is exchanged for carbon dioxide as waste carries blood cell activity, and then exhale.
