Procalcitonin for Early Detection of Pharyngocutaneous Fistula after Total Laryngectomy: A Pilot Study.

OBJECTIVES: The aim of this prospective study was to investigate the role of procalcitonin as an early diagnostic marker of pharyngocutaneous fistula (PCF) in a cohort of head and neck patients treated with total laryngectomy for squamous cell carcinoma. METHODS: This prospective study was conducted on a sample of patients enrolled from January 2019 to March 2022. All patients were subjected to a "protocol" of blood chemistry investigations, scheduled as follows: complete blood count with formula, ESR dosage, CPR, and PCT. PCT was also dosed by salivary sampling and a pharyngo-cutaneous swab in patients who presented with PCF. The dosage scheme was systematically repeated: the day before the intervention (t0); the 5th day postoperative (t1); the 20th day postoperative (t2); and at time X, the day of the eventual appearance of the pharyngocutaneous fistula. RESULTS: A total of 36 patients met the inclusion criteria. The patients enrolled in the study were subsequently divided into two groups: 27 patients underwent total laryngectomy (TL) for laryngeal cancer without postoperative complications, and 9 patients were undergoing TL with postoperative PCF. Using the Cochran's Q test, statistical significance was found for PCT among T0, T1, Tx, and T2 (p-value < 0.001) between the PCF and non-PCF groups. The Z test demonstrated that there is a difference in PCT levels at T1 and T2 and that this difference is statistically significant (p < 0.001). CONCLUSIONS: PCT could be considered an early marker of complications in open laryngeal surgery. According to our results, it could be useful in the precocious detection of pharyngocutaneous fistulas and in the management of antibiotic therapy.

New Therapeutic Strategies in the Treatment of Stomal Recurrence After Total Laryngectomy: Role of Immunotherapy.

OBJECTIVE: The aim of this study was to investigate the incidence of stoma recurrence and the therapeutic strategy outcomes in relation to survival that have been adopted over the past few decades using a monoclonal antibody, specifically nivolumab. METHODS: This study included a total of 487 patients diagnosed with laryngeal carcinoma undergoing either a laryngectomy or salvage surgery after conservative interventions at the ENT Unit of Federico II University in Naples, Italy, between 2011 and 2021. Following a minimum 2.5-year follow-up and a maximum 21-year follow-up, the results revealed that only 38 patients suffered a stomal recurrence. RESULTS: Despite various adopted treatment strategies, the literature reports lower patient survival rates. Following a total laryngectomy, stomal recurrence represents a therapeutic management challenge due to a poor prognosis for nearly every treated case. According to the literature, in fact, despite a low incidence (ie, 0.8-31.3%), the overall mortality rate increases from 77% to 100% after three years. Nevertheless, introducing immunotherapy into cancer treatment has resulted in an observable revolution in the treatment of different types of cancers over the years. CONCLUSION: In light of recorded data on survival following the use of the nivolumab, the case presented in this study allows a new perspective of successfully treating recurrences of squamous carcinoma of the head and neck.

Usefulness of transthoracic echocardiogram in management of cardiac involvement in large B-Cell lymphoma: a case report.

Primary lymphoma often involve the heart, especially the right side. Prompt diagnosis is necessary to start the right therapy and decrease symptoms and death risk rate. Transthoracic echocardiogram is the first line exam to perform when symptoms are suspicious of mediastinal mass.

Intravenous versus intracoronary bolus of glycoprotein IIb/IIIa inhibitor administration during primary percutaneous coronary intervention on long-term left ventricular systolic and diastolic function.

BACKGROUND: In primary percutaneous coronary intervention (PCI), glycoprotein (GP) IIb/IIIa inhibitors are often given in order to attain and maintain better myocardial perfusion. We tested the hypothesis that intracoronary (IC) bolus of GP IIb/IIIa inhibitors might produce a greater improvement in left ventricular (LV) systolic and diastolic function than an intravenous(IV) bolus. METHODS AND RESULTS: Seventy seven patients undergoing primary PCI for their first ST elevation myocardial infarction (STEMI) were randomly assigned to either an IC or IV bolus of GP IIb/IIIa inhibitor, followed by IV infusion. Compared with the echocardiographic findings within 3 days after PCI, LV ejection fraction was higher at 1 year, with no significant differences between the IV and IC groups (IV: 44% vs. 49%, p = 0.001; IC: 43% vs. 48%,p < 0.001). LV diastolic function (E/E') did not significantly change at 1 year by either approach. CONCLUSIONS: LV systolic function improved by a similar magnitude following primary PCI, with either IC or IV bolus administration of GP IIb/IIIa inhibitor therapy. However, no significant changes were observed in LV diastolic function.

Sudden death and physical exercise: timely diagnosis of congenital anomalies of the coronary arteries with the new 320-slide multi-detector computed tomography.

Congenital abnormalities of the coronary arteries here described are an uncommon form of structural heart disease. Nevertheless, they deserve attention because may cause chest pain and, in some cases, sudden cardiac death even during exercise. Traditional angiography has limitations due to its projectional and invasive nature. The recent development of the 320-slide multi-detector computer tomography with low radiation exposure has the potential to modify the current diagnostic work-up, as it allows even in young people a timely identification of clinical significant coronary anomalies minimizing the risks related to radiation exposure.
