Medullary thyroid carcinoma (MTC) is a type of thyroid neoplasm which originates from parafollicular cells, and it is commonly diagnosed by calcitonin screening. Besides the sporadic form, the heritable form of MTC is characterized by constitutive activation of the RET (REarranged during Transfection) proto-oncogene caused by different mutations. ⋯ The RET gene mutation profile has a unique distribution in this study population when compared with the other European populations. The mutations in codon 634 are most common; therefore the cost-reducing genetic screening should primarily target this codon, and if the negative outcome appears, then other codons should be examined in the order that depends on their occurrence.

Although effective treatment in terms of inducing virological and biochemical response for chronic hepatitis B (CHB) is available, its effect on the clinical course of the disease has not yet been accurately estimated. Objective of this study was to evaluate the effect of antiviral therapy and its type [interferon +/- nucleos(t)ide analogs (NAs) vs. NAs] on the occurrence of a clinical event (liver decompensation, liver transplant, hepatocellular carcinoma and death from a liver-related cause) in CHB patients. ⋯ Data from observational studies can provide useful inference, provided they are analyzed appropriately. The current study has shown that the available treatment options for CHB offer a significant clinical benefit to CHB infected individuals. Hippokratia 2016, 20(3): 214-221.

Bone involvement represents a common symptom at diagnosis in children with acute lymphoblastic leukemia, and its prognostic value is not entirely clarified. The aim of this study was to evaluate bone involvement at diagnosis in children with acute lymphoblastic leukemia as a predictive factor and to correlate its presence with other demographic, clinical, and laboratory findings. ⋯ The presence of bone involvement at diagnosis is related with immunophenotype of B-acute lymphoblastic leukemia, lower mean age, lower mean white blood cell count and good prednisone response. According to presented data, we conclude that the presence of bone involvement at diagnosis represents a positive predictive factor for outcome/survival. Hippokratia 2016, 20(3): 227-230.

Left atrial appendage pericardial fluid: contrast-enhanced transesophageal echocardiography makes it visible.
Contrast-enhanced transesophageal echocardiography (TEE) for the opacification of left atrial appendage (LAA) is not clearly suggested by the current guidelines and only scarce data are available. ⋯ Contrast-enhanced TEE has been demonstrated to safely and accurately enlighten LAA anatomy.

Case Reports
Unusual case of stroke related to Kocuria Kristinae endocarditis treated with surgical procedure.
We report the case of a 35-year-old man with stroke related to infective endocarditis (IE) caused by Kocuria kristinae. ⋯ The patient with chronic hepatitis C virus infection and a former intravenous drug user developed a stroke suddenly, after three months duration of fever and malaise. Duplex ultrasonography of the carotid arteries (zero level diastolic flow, diastolic reversed flow) focused attention to cardiac valve pathology and endocarditis (definite confirmation was made by transesophageal echocardiography). Kocuria kristinae was grown from the blood culture and antibiotic therapy administered, according to the antibiogram, did not cure the infection and the patient underwent an aortic valve replacement with a mechanical prosthesis and debridement of the mitral valve. One year after the surgery, the patient had no subjective problems and neurological findings were normal. Conclusion: To our knowledge, this is the first case of IE caused by Kocuria kristinae, which was diagnosed after the development of stroke, where IE was suspected based on Duplex ultrasonography of the carotid arteries. This is the second case of infection by this bacterium which could not be cured by antibiotics only and had to be submitted to surgical intervention. Hippokratia 2016, 20(3): 231-234.
