[Analysis of the organ allocation system for liver transplantation in Chile].
In Chile, organ allocation for liver transplantation (LT) in adults is prioritized according to the MELD-Na score. Exceptions such as Hepatocellular Carcinoma (HCC) and other non-HCC exceptions receive a score called Operational MELD score. ⋯ MELD-Na score can discriminate very well patients who have a higher risk of death in the short and medium term. However, the assignment of operational scores for situations of exception produces inequities in the allocation of organs for LT and must therefore be carefully adjusted.

[Prevalence of transmitted drug resistance in HIV-infected treatment-naive patients in Chile].
Transmitted drug resistance (TDR) occurs in patients with HIV infection who are not exposed to antiretroviral drugs but who are infected with a virus with mutations associated with resistance. ⋯ These results should prompt a change in recommendations for starting antiretoviral therapy, especially in first-line regimens that include non-nucleoside reverse transcriptase inhibitors.

[Cannabis use among hospitalized young people experiencing a first episode of psychosis: a case control study].
Cannabis use among young people in Chile has increased significantly in the last years. There is a consistent link between cannabis and psychosis. ⋯ Cannabis use is related to psychosis in this Chilean group of patients. This relationship is stronger in patients with early exposure to the drug and longer the regular use. One of every five admissions due to psychosis is associated with cannabis consumption. These data should influence cannabis legisla-tion and the public policies currently being discussed in Chile.

Case Reports[Lupus erythematosus associated with erythema multiforme or Rowell's syndrome. Report of one case].
Rowell's syndrome is characterized by an association of lupus erythematosus and erythema multiforme, with distinctive laboratory findings. Its treatment is similar to lupus. We report a 16-year-old female presenting with skin lesions, laboratory and histology consistent with this entity. Because of the spread of cutaneous involvement and development of epidermal detachment, she required therapy with intravenous corticosteroids and gamma globulin.

Giant cell arteritis (GCA) is a primary granulomatous systemic vasculitis involving the aorta and its main branches that affects people aged over 50 years with a genetic predisposition. Its main phenotypes are cranial and extracranial involvement, with or without symptoms of polymyalgia rheumatica. These phenotypes can overlap. ⋯ These imaging techniques are complementary, and their use is highly recommended. GCA treatment is based on steroidal therapy, often associated with a corticosteroid-sparing immunosuppressive agent. The follow-up is eminently clinical.
