Open surgery is a reliable choice for congenital subglottic stenosis, that represents the third most common congenital anomaly of the larynx. One of the procedures performed is anterior laryngotracheal reconstruction (LTR) with anterior rib graft. The objective of this preliminary study was to evaluate the potential of 3D printing technology for the realization of laryngo-tracheal scaffold in Polycaprolactone (PCL) implanted in vivo in ovine animal model.

A 3D computer model of a laryngeal graft and a tracheal graft was designed and printed with PCL through 3D additive manufacturing technology. The scaffolds were seeded with autologous mesenchymal stem cells and cultured in vitro for up to 14 days. Anterior graft LTR with 3D printed scaffolds was performed on 5 sheep. The animals underwent endoscopic examinations at the first, 3rd, 6th, and 12th weeks after surgery and before sacrifice. The integration of the material was evaluated by the pathologist.

Two animals showed a favourable postoperative courseaft, to achieve greater integration into surrounding tissues. Bioconstructed grafts could simplify surgery for the treatment of laryngo-tracheal stenosis, particularly in the treatment of long tracheal stenoses, which have, at the moment, very complex surgical options.

This analysis investigates any potential differences in pulmonary function test (PFT) outcomes among pediatric patients with cystic fibrosis (CF) receiving both medical management (MM) and functional endoscopic sinus surgery (FESS) versus MM alone for CF exacerbation.

Prospective cohort.

Pediatric tertiary care facility.

The data was prospectively collected from July 2011 to March 2020. Diagnosis of CF and age≤to 18 were required. All patients were hospitalized and treated for CF exacerbations with both FESS with MM and MM alone at variable time intervals, although the order of initial treatment received differed. Two-way ANOVA with repeated measures were used to determine the effect of receiving FESS with MM versus MM alone on PFT outcomes over time (during admission, at discharge, at 3 months, at 6 months, and at 12 months).

13 pediatric patients, 7 of which had FESS with MM initially and 6 who had MM alone initially, and 20 events of both FESS and MM were included for analysis. For PFT outcomes, there was no statistically significant two-way interaction between treatment type and time following treatment, p=0.492. The main effect of treatment did not show a statistically significant difference in FEV1 between treatment types, p=0.737. There was no statistically significant association between treatment type and time between hospital readmission in months, p=0.111.

There was no significant difference between PFT outcomes in pediatric patients hospitalized for CF exacerbation treated with MM with or without FESS at any time interval.

Metastatic spread of malignant melanoma to the abdomen presents a therapeutic challenge. Targeted and Immune-therapies dramatically improve patients' survival, yet some patients may still benefit from surgical intervention. This study investigates the outcomes of surgical treatment of abdominal metastatic melanoma in the era of modern therapy.

This is a retrospective study of all patients who underwent surgical resection for abdominal metastatic melanoma between the years 2009-2021 (n=80). We examined the clinical, operative, perioperative, and oncological outcomes of these patients.

The cohort included a therapeutic group (T, n=43) and palliative group (P, n=37). The rate of overall post-operative complications was lower in the T group (n=3, 9.3%) compared to the P group (n=10, 27.1%) (p=0.04), but no difference in major complications rate (p=0.41). The median follow-up was 13.4 months (range, 0.5-107), with an estimated 2- and 5-years survival of 66.5% and 45.3% respectively. The estimated 2- and 5-yestesectomy is a safe and oncologically efficacious therapy in selected patients. Especially in the era of modern therapeutics, patients with isolated disease site, limited resectable progression on therapy, or patients with symptomatic metastases should be considered for surgical resection.
Primary tumor resection (PTR) in patients with metastatic unresectable colorectal cancer is less and less used to prevent local complications. Although its therapeutic effect is debated, poor data are available about the activity of chemotherapy (CHT) after PTR. The study aims to evaluate trials that compared PTR followed by CHT vs. CHT alone.

After a literature search on two databases by predefined criteria, studies published from 2011 to 2021 were selected. All studies evaluating the progression-free survival (PFS) of patients receiving CHT after PTR or not were included in a meta-analysis. Finally, 18 possible moderating variables were extracted from each study and examined.

Eleven trials reported a reduced risk of progression after first-line CHT among patients receiving PTR (HR 0.72, CI 0.66-0.79). The heterogeneity was moderate (Q=17.52; p-value=0.093) and the grade of inconsistence intermediate (I
=37.21%). Among moderating variables, female sex and low percentage of patients with liver metastases were related with a stronger effect size of PTR on PFS, whereas a longer OS and a trend to better PFS was evident after poly-chemotherapy regimens.

PTR could improve the results of first-line CHT in patients with unresectable colorectal cancer with low tumor burden only in the subgroup receiving more aggressive chemotherapy.

Map regional lymph node metastases for lateralized oral cavity squamous cell carcinoma (OCSCC) and evaluate factors associated with regional metastases and recurrence.

Retrospective cohort study of 715 patients with lateralized OCSCC surgically treated in 1997-2011. Analysis was performed using log-rank, Kaplan-Meier, and multivariable logistic and Cox regression.

Regional metastases were identified in ipsilateral levels IIA (24%), IB (18%), III (13%), V (9%), IV (7%), IA (2%) and IIB (1%) and the contralateral neck (3%). Lymphovascular invasion (LVI) (Hazard Ratio [HR] 2.2, 95% Confidence Interval [CI] 1.2-3.9) and T category (T3 vs. T1 HR 4.1, 95% CI 1.9-9.3; T4 vs. T1 HR 2.3, 95% CI 1.2-4.3) were associated with regional metastases. Most (71%) isolated regional metastatic recurrences were in undissected levels of the neck, including 58% in levels IV and V. Tumors of the hard palate (HR 4.3, 95% CI 1.2-16.1), upper alveolus (HR 3.2, 95% CI 1.0-4.7) or with LVI (HR 2.0, 95% CI 1.0-3.9) were associated with isolated regional recurrence. For upper alveolar/hard palate tumors, depth of invasion (DOI) ≥4mm(P= .003) and LVI (P= .04) were associated with regional metastases.

For lateralized OCSCC, elective neck dissection of level IIB or the contralateral neck may rarely be needed, but additional surgical or radiation treatment of levels IV and V may be considered based on patient risk factors, including T category 3-4 or LVI. For upper alveolar/hard palate tumors, DOI ≥4mm is an appropriate threshold for elective neck dissection.

There were two outbreaks of SARS-CoV-2 infection in the facility at the beginning and end of October 2021, respectively. All residents in the facility were screened for SARS-CoV-2 infection using RT-PCR as part of the investigation of the second outbreak. Twelve residents, who had infection confirmed during the first outbreak, were found to be re-positive for RT-PCR test at the second outbreak. 8 Of 12 RT-PCR re-positive cases were confirmed as reinfections based on investigation through the whole genome sequencing, viral culture, and serological analysis, despite of the short interval between the first and second outbreaks (29-33 days) and a history of full vaccination for 7 of the 12 re-positive cases. This study suggests that decreased immunity and underlying health condition in older adults makes them susceptible to reinfection, highlighting the importance of prevention and control measures regardless of vaccination status in long-term care settings.
To compare adverse outcomes among preterm births that underwent cesarean delivery (CD) for non-reassuring fetal heart rate tracing (NRFHT) versus those that did not.

Consortium on Safe Labor Database was utilized for this secondary analysis. Inclusion criteria were non-anomalous, singleton at 23.0 to 36.6weeks who labored for at least 2h. Composite adverse neonatal outcomes included any of the following intraventricular hemorrhage grade III or IV, seizures, mechanical ventilation, sepsis, necrotizing enterocolitis 2 or 3, or neonatal death. Composite adverse maternal outcomes included any of the following postpartum hemorrhage, endometritis, blood transfusion, chorioamnionitis, admission to intensive care unit, thromboembolism, or death.

Of 228,438 births, 29,592 (13.0%) delivered preterm, and 16,679 (56.4%) labored for at least 2 hrs. CD for NR FHRT was done in 1,220 (7.3%). The rate of composite adverse neonatal outcome was different among those that had CD for NR FHRT (26.7%) versus those that did not (16.6%; aRR 1.59, 95% CI 1.43-1.76). Composite adverse maternal outcomes did not differ between the groups. The area under the curve for risk factors to identify composite adverse neonatal outcome was 0.81, and for composite adverse maternal outcomes, 0.64.

Subsequent to CD for NR FHRT, composite adverse neonatal outcome is 59% higher among preterm births when compared to delivery with reassuring tracing; composite adverse maternal outcomes did not differ between the groups.
