Unroofed coronary sinus syndrome (UCSS) is rare and often associated with the left superior vena cava (LSVC). We report our experience of the clinical features, diagnosis, associated anomalies, surgical procedures, and late outcomes of UCSS during a 20-year period.
One hundred and fifty-nine patients with UCSS were treated surgically and followed up between May 1998 and May 2019. UCSS was confirmed by preoperative echocardiography or computerized tomography (CT) scan in 97 patients and by the surgeons intraoperatively in 62 cases, and 100 cases were associated with LSVC. Among these patients, eight cases underwent ligation, and the intracardiac tunnel or baffle was reconstructed in 71 cases to ensure drainage of the LSVC into the right atrium (RA), and the extracardiac procedure was to lead the LSVC into the RA in three patients. Coronary sinus opening was diverted to the RA by the atrial septal patch in three cases. Thirteen patients underwent the reroof procedures, and two patients had untreated LSVC. The associated cardiac lesions were corrected concomitantly.
There were five in-hospital deaths. Follow-up of 143 patients of early survivors was done, and no deaths were reported. No serious complications were observed, with the exception of avulsion of the internal tunnel patch in one patient.
UCSS is often misdiagnosed during preoperative evaluation of congenital heart diseases. Preoperative transthoracic echocardiography remains the most important method in the diagnosis of UCSS. We adopted multiple surgical approaches to manage the different types of UCSS with LSVC with good results.

Hypothermia in combination with cerebral perfusion offers optimal results by maintaining the brain's metabolic supply. Both retrograde cerebral perfusion and antegrade cerebral perfusion, used in combination with hypothermia, produce comparable results when the hypothermic circulatory arrest times are short; in contrast, for longer perfusion times, most aortic surgery centers are trending toward the use of antegrade rather than retrograde cerebral perfusion. Our own preference has been to use a bilateral mode of delivering antegrade cerebral perfusion instead of a unilateral approach, as bilateral perfusion appears to be more protective. We maintain that there is no harm in perfusing both brain hemispheres, so long as an appropriate balloon-tipped catheter is used carefully and manipulation of the head vessels is avoided.
Swallowing disorders are common problems after partial laryngectomy. The aim of this study is to illustrate the long-term functional results of rehabilitation of swallowing by polydimethylsiloxane (PDMS) injection.
Twenty-eight patients with dysphagia after partial laryngectomy who underwent injection of PDMS for rehabilitation of swallowing were included in the study. Impairment of swallowing and quality of life (QoL) were investigated with questionnaires M. D. Anderson Dysphagia Inventory (MDADI) and Performance Status Scale for Head and Neck Cancer (PSS-HNC). Functional results at fiberoptic endoscopic evaluation of swallowing (FEES) were analyzed using a modified penetration-aspiration scale.
Mean follow-up was 8.5 years. Twenty-six patients showed an improvement at questionnaires (p < 0.001). Median improvement was 6 (p < 0.001) in the modified penetration-aspiration scale. Total laryngectomy was required in one patient.
PDMS injection is a good option for rehabilitation of swallowing in case of dysphagia after partial laryngectomy. It improves QoL and the results persist after a long follow-up period.

In Europe, the SARS-CoV-2 pandemic had its first epicenter in Italy. Despite a significant mortality rate, the severity of most cases of COVID-19 infection ranges from asymptomatic to mildly symptomatic, and silent infection affects a still-unknown proportion of the general population. No information is available on the prevalence and clinical impact of SARS-CoV-2 silent infection among patients with cancer receiving anticancer treatment during the pandemic.
From April 1, 2020, to the end of the same month, 560 consecutive patients with cancer, asymptomatic for COVID-19 and on anticancer treatment at Papa Giovanni XXIII Hospital in Bergamo, were evaluated and tested for SARS-CoV-2. We implemented a two-step diagnostics, including the rapid serological immunoassay for anti-SARS-CoV-2 immunoglobulin (Ig) G/IgM and the nasopharyngeal swab reverse transcriptase-polymerase chain reaction (RT-PCR) test in case of seropositivity to identify SARS-CoV-2 silent carriers.
In 560 patients, 172 (31%) resulted positictive two-step diagnostics was implemented to ascertain SARS-CoV-2 silent carriers. In this series, consisting of consecutive and unselected patients with cancer, the prevalence of both SARS-CoV-2-seropositive patients and silent carriers is substantial (31% and 10%, respectively). Trametinib clinical trial The early safety profile of the different anticancer therapies, in patients previously exposed to SARS-CoV-2, supports the recommendation to continue the active treatment, at least in case of RT-PCR-negative patients.
