[INTRODUCTION - Herpes simplex virus is a rare and severe disease, which is often lethal, especially in children and those who underwent transplantation. Rapid diagnostic help determines therapy and facilitates recovery of the patient. CASE REPORT - The authors present a case of a 46-year-old patient with no underlying disease, in whom the diagnosis of hepatitis caused by herpes simplex-1 virus was suggested after histological evaluation of a blind liver biopsy specimen. The diagnosis was later confirmed by immunomorphological examination. The patient’s hepatitis resolved following acyclovir therapy, but he developed nosocomial pneumonia, sepsis caused by Candida albicans and anuria. The patient recovered due the joint efforts of an infectologist, a pathologist, an intensive care specialist and a nephrologist. CONCLUSION - During examination of the patient, immune suppression was not indicated either by HIV-serology or bone marrow biopsy. thus the findings were presumably explained by a generalised infection in an immunocompetent host. In the case described, histological examination of the liver biopsy was a life-saving procedure, because it allowed timely and efficient treatment.]

[INTRODUCTION - Sarcoidosis is a relatively common multisystemic disorder. Chest involvement is most frequent, but any organ can be involved. In case of abdominal lesions the suspicion of sarcoidosis rarely arises. CASE REPORT - A 53-year old female patient with a history of crural pain unresponsive to medications and weight loss of unknown origin was sent to the internist. Hypercalcemia and bone pain suggested multiple myeloma, however, this diagnosis could not be confirmed. Chest X-ray examination was negative. Splenomegaly and multiple hypodens splenic and hepatic lesions were detected by ultrasound and abdominal computed tomography. Finally, ultrasound guided biopsy of the liver proved stage II sarcoidosis. Steroid therapy was initiated and the splenic and hepatic lesions seen with ultrasound and CT scan disappeared. CONCLUSION - Sarcoidosis is usually suspected following chest X-ray or during chest CT examination. Nevertheless, our case demonstrates that multiple lesions in the spleen or liver may indicate sarcoidosis even in the absence of thoracic lesions. Biopsy taken from the lesions can lead to adequate diagnosis.]

[The rapidly spreading SARS-CoV2 respiratory virus has evoked an epidemic with serious aftermath around the world. In addition to the health effects, the global economic damage is actually unpredictable. At the same time, the pandemic has launched a series of unprecedented collaborative scientific research, including the development of vaccines. This study summarizes up-to-date information on vaccines, immune memory, and some emerging clinical effects.]
