Headache, nausea, vomiting, papilledema, somnolence, seizures, personality changes and focal neurological deficits develop within days or weeks.

Lassa Fever

Monday, May 24th, 2010

Lassa fever is part of the viral hemorrhagic fevers (FEV), diseases of viral origin in systemic nature, characterized by sudden onset, acute and often accompanied by hemorrhagic manifestations. In general, the staff responsible for Fev are RNA viruses (arena-viruses, bunyavirus, filo-virus, flavivirus), whose survival is ensured by natural reservoirs such as animals or insects. The viruses are geographically confined areas where the host species live.

Lassa fever is named after the Nigerian city where, in 1969, two missionary nurses died from the disease, hitherto unknown. The causative agent is a RNA virus belonging to the family of Arenaviridae, widespread mainly in Africa, which are the main reservoir rodent Mastomys.

Transmission Mode
As for all the hemorrhagic fevers, men are not natural reservoirs for the virus, but can be infected through contact with infected animals or arthropod vectors. Lassa fever was transmitted by direct contact with rodent excreta or through aerosol excreta and saliva of rodents.

In some cases, after the accidental transmission, can be transmitted between humans, direct contact with blood, tissue, secretions, or excretions of infected people, especially within the family and nosocomial. (more…)

HPV Infections

Sunday, May 23rd, 2010

Human papillomaviruses (HPV) are DNA viruses that are sexually transmitted and replicated in cells. There are over 120 types of HPV, which differ in the types of tissue they infect. More than 40 types affect the anal and genital epithelium (cervix, vagina, vulva, rectum, urethra, anus, penis) and some of these are defined HPV high-risk are those related to the emergence of various types of tumors, especially of the cervix, but also the penis, anus, vulva, and others.

Of high-risk HPV, HPV 16 and the 18 are those most frequently implicated in cervical cancer, being responsible respectively for about 60% and 10% of all cervical cancers. Other high-risk types are associated with cervical cancer, but less frequently, while low risk HPV (those not linked to cancers) can still cause anogenital warts in both sexes.

Most HPV infections are transient, because the virus is eliminated by the immune system before developing a pathogenic effect. In case of persistent infection, the time between infection and the occurrence of precancerous lesions is about five years, while the latency for the onset of cervical cancer can be 20-30 years.

A successful transplant not only frees the patient from a long dialysis, but also provides other metabolic functions of the kidney.

kidney transplant

The survival of patients one year after transplantation from living relative donor is> 95%, with approximately 90% of allografts functioning. Subsequently, there has been an annual loss of transplants varies from 3 to 5%, including those due to death of the patient. The one-year survival rate of patients undergoing cadaveric transplantation is approximately 90% and graft survival varies between 70 and 90%, depending on the centers. In subsequent years, you lose a 5-8% of transplants each year. At present, many renal transplant recipients are carrying bodies are working more than 30 years. Although it was previously believed that patients over 55 years, the transplant would entail an unacceptable risk, the more sophisticated use of immunosuppressive drugs and the close immunological control allow you to allografts in selected patients during the 7th decade of life and beyond.
