Nationwide Survey in Greece about Knowledge, Risk Perceptions, and Preventive Behaviors for COVID-19 during the General Lockdown in April 2020.

Background: The aim of this study was to investigate the knowledge, attitudes, and practices of the Greek general population toward coronavirus disease 2019 (COVID-19) during the lockdown period in April 2020, to examine factors associated with misperceptions and to determine behavioral patterns that may require interventions.

Methods: A cross-sectional study of the general Greek population ( = 1858) was conducted. A geographically stratified cluster sampling was implemented.

Metastatic acinic cell carcinoma of the parotid gland to the abdominal wall.

Acinic cell carcinoma (ACC) is a low-grade malignant salivary neoplasm. The parotid gland is the predominant site of origin. ACC has a tendency to recur and metastasize, rarely enough to soft tissue as well as other sites.

Successful Living-Related Renal Allograft in a Recipient With Factor V Leiden Deficiency: A Case Report.

Thrombophilia due to activated protein C resistance (Leiden mutation) is the most common inherited thrombophilic disorder with 5% incidence in whites. Renal transplant of these patients entails a risk of vascular thrombosis soon after the transplant; and acute rejection episodes and graft loss within the first year. We present a case of a successful living-related renal transplant in man with a recent history of repeat episodes of vascular access thrombosis attributed to inherited thrombophilia (heterozygosity for factor V mutation Q506 and homozygosity for mutation T677 for methylene-tetrahydrofolate reductase).

Cystinuria: current diagnosis and management.

Cystinuria is an inherited disorder of the dibasic amino acid transport system in the proximal tubule and the small intestine. Two responsible genes have been identified, the SLC3A1 on chromosome 2 and the SLC7A9 on chromosome 19. The inability of renal tubules to reabsorb cystine and the relative insolubility of cystine at physiological urine pH lead to stone formation.

Spontaneous thrombus formation in a normal left ventricle following administration of large doses of epoietin.

We present a case of a thrombus formation within the left ventricle of a patient with a normal heart, who had previously been receiving high doses of erythropoietin for an inappropriately prolonged period.
