Percutaneous tracheostomy is a minimally invasive operation performed in patients, in order to provide an air passage through the windpipe. A rare cause of severe bleeding during such operation is the injury of the thyroidea-ima artery. This case report presents a patient with hemorrhage after thyroidea-ima injury during percutaneous dilatational tracheostomy. Surgeons should always be aware of such anatomic variation, in order to prevent urgent sternotomy.

Background: The purpose of this study is to investigate the levels of burnout among Greek residents, highlighting potential differences between those practicing at home and abroad, as well as to investigate correlations with demographic, individual and labor factors. Methods: The research was conducted on a sample of 131 residents, using an anonymous questionnaire which included demographic, individual and labor characteristics, Maslach’s Burnout Inventory, questions regarding job and life satisfaction levels, working conditions and the impacts of the economic recession. Results: Fifty two point seven percent of the sample were training in the Greek National Health Service (N.H.S.), 27.5% in Germany and 19.8% in the United Kingdom. One out of three residents in the Greek system showed high levels of burnout in all three dimensions of the syndrome, while 51.1%, 72.2% and 30.8% of the Greek, British and German team, respectively, appeared burnt out simultaneously in two dimensions. Levels of job and life satisfactions ranged on average, while workload appeared heavy. Conclusions: The occurrence of burnout was associated with gender, specialty, employment characteristics (working hours, autonomy, support etc.), proneness to accidents, country, job satisfaction and quality of life, but was not associated with age or marital status. No correlation was found with susceptibility to medical errors.

BACKGROUND:The worldwide spread of the severe acute respiratory syndrome-coronavirus-2 (SARS-COV-2) has created unprecedented situations for healthcare professionals and healthcare systems. Although infection with this virus is considered the main health problem currently, other diseases are still prevalent. CASE REPORT:This report describes a 59-year-old man who presented with symptoms of dyspnea and fever that were attributed to Covid-19 infection. His clinical condition deteriorated and further examinations revealed a subjacent severe aortic regurgitation due to acute infective endocarditis. Surgical treatment was successful. CONCLUSIONS:The results of diagnostic tests for Covid-19 should be re-evaluated whenever there are clinical mismatches or doubts, as false-positive Covid-19 test results can occur. Clinical interpretation should not be determined exclusively by the Covid-19 pandemic. This case report highlights the importance of using validated and approved serological and molecular testing to detect infection with SARS-CoV-2, and to repeat tests when there is doubt about presenting symptoms.

Perceval-S has become a reliable and commonly used option in surgical aortic valve replacement (AVR) since its first implantation in humans 15 years ago. Despite the fact that this aortic valve has been proven efficient enough in the short and mid-term period, there is still lack of evidence for the long-term outcomes. This is an observational retrospective study in a high-volume cardiovascular center. Pertinent data were collected for all the patients in whom Perceval-S was implanted from 2013 to 2020. The total number of patients was 205 with a mean age 76.4 years. Mean survival time was 5.5 years (SE = 0.26). The overall survival probability of patients undergoing aortic valve replacement with Perceval-S at 6 months was 91.0% (Standard Error SE = 2.0%), at one year 88.4% (SE = 2.3%) and at 5-years 64.8% (SE = 4.4%). A detrimental cardiac event leading to death was the probable cause of death in 35 patients (55.6%). The initiation of Transcatheter Aortic Valve Replacement (TAVR) program in our center in 2017 was associated with a decline in the number of very high-risk patients treated with sutureless bioprosthesis. This fact is demonstrated by the significant shift towards lower surgical risk cases, as median Euroscore II was reduced from 5,550 in 2016 to 3,390 in 2020. Mini sternotomy was implemented in 79,5% of cases favoring less invasive approach. Low incidence of reinterventions, patient prosthesis mismatch and structural valve degeneration was detected. The survival rate after aortic valve replacement with implantation of Perceval-S is satisfactory in the long-term follow-up. Cases of bioprosthesis dysfunction were limited. Mini sternotomy was used in the majority of cases. TAVR initiation program impacted on the proportion of patients treated with Perceval-S with reduction of high-risk patients submitted to surgery.

Gynecomastia with mastodynia and galactorrhea as a paraneoplastic syndrome due to lung cancer with complete response after surgical excision is rare. A 62-year-old Caucasian male presented with mastodynia, galactorrhea and right breast enlargement. Chest x-ray revealed a left upper lobe tumor. The patient had high levels of serum beta-human chorionic gonadotropin (b-HCG) and prolactine. Complete staging was negative for metastases. A typical left upper lobectomy with radical mediastinal lymph node dissection was performed. Pathology report was consistent with a poorly differentiated adenocarcinoma (T2N1M0). Immunohistochemically, multinucleate cells and occasional mononucleate tumor cells showed positivity for human chorionic gonadotropin. The patient received adjuvant chemotherapy with cisplatin - navelbine. One year later physical examination showed regression of both gynecomastia and mastodynia and there was no nipple discharge, while he is free from local or distant metastatic disease and the b-HCG level is normal (1,59 mIU/ml). This case represents a very rare, first manifestation of lung cancer. Galactorrhea, mastodynia and gynecomastia were the initial symptoms, which totally resolved following the successful surgical resection and adjuvant chemotherapy. In this case, prolactin and b-HCG are useful biomarkers during follow up for checking local or distal recurrence of the disease.
