Objective The aim of this study was to compare in vivo effect of five pharmacological options on inflammation and pulmonary fibrosis induced by paraquat. Methods 54 Wistar SPF rats were used. After 2 h post-intoxication with paraquat ion, groups of 9 animals were randomly assigned to (1) cyclophosphamide plus dexamethasone (2) low molecular weight heparin (3) unfractionated heparin (4) vitamin C every 24 h, (5) atorvastatin or (6) placebo with intraperitoneal saline. Lung inflammation, alveolar injury, hepatocyte damage, hepatic regeneration, acute tubular necrosis and kidney congestion were evaluated. Results In the control group 100% of animals presented moderate and severe lung inflammation, while in the groups with atorvastatin and intratracheal heparin this proportion was lower (55.5%; CI 26.6–81.3%) (p = 0.025). A lower degree of moderate or severe hepatic regeneration was evident in the treatment groups with atorvastatin (p = 0.009). In this study was demonstrated that statins and heparin might have a protective effect in the paraquat-induced destructive phase. More evidence is needed to evaluated of dose–response effects of these drugs before to study in clinical trials.

Hepatosplenic T-cell lymphoma (HSTCL) is a rare, aggressive type of peripheral T -cell lymphoma characterized by infiltration and proliferation of atypical T-cells within the sinusoids of the spleen, liver, and bone marrow. This case report consists of a young male, who was admitted to a local hospital with a history of unexplained fever, odynophagia, and rash, initially mimicking infectious disease. The patient died due to multiorgan failure and the correct diagnosis only was accomplished in the autopsy. This case highlights the difficulty of diagnosing HSTCL and the necessity of considering it in patients with unknown origin fever with hyperferritinemia.

La malacoplaquia es una enfermedad granulomatosa crónica inicialmente descrita en las vías urinarias, pero posteriormente encontrada en múltiples órganos. La presentación clínica depende del sitio comprometido; en el tracto urinario produce disuria, dolor pélvico o abdominal, fiebre, malestar general y, a veces, sensación de masa. Su etiopatogenia aún no ha sido completamente entendida, pero se cree que es debida a un trastorno en la función lisosomal de los macrófagos que afecta la destrucción de las bacterias. Histológicamente se caracteriza por presentar macrófagos llamados "células de von Hansemann" e inclusiones de Michaelis-Gutmann. Describimos el caso de una paciente con diabetes mellitus de larga evolución y malacoplaquia renal que le produjo síntomas debilitantes crónicos.

Objective : The aim of this study was to compare in vivo effect of five pharmacological options on inflammation and pulmonary fibrosis induced by paraquat. Methods: 54 Wistar SPF rats were used. After 2 hours post-intoxication with paraquat ion, groups of 9 animals were randomly assigned to : (1) cyclophosphamide plus dexamethasone (2) low molecular weight heparin (3) unfractionated heparin (4) vitamin C every 24 h , (v) atorvastatin or (vi) placebo with intraperitoneal saline .Lung inflammation, alveolar injury, hepatocyte damage, hepatic regeneration, acute tubular necrosis and kidney congestion were evaluated. Results: In the control group 100% of animals presented moderate and severe lung inflammation, while in the groups with atorvastatin and intratracheal heparin this proportion was lower (55.5% ; CI 26.6 – 81.3%) (p = 0.025). A lower degree of moderate or severe hepatic regeneration was evident in the treatment groups with atorvastatin (p = 0.009). In this study was demonstrated that statins and heparin may have a protective effect in the paraquat-induced destructive phase. More evidence are needed to evaluated of dose response effects of these drugs before to study in clinical trials.
