alexandrossfakianakis shared this article with you from Inoreader
The aim of this study was to compare the effects of maxillomandibular advancement (MMA) on respiratory function between obstructive sleep apnoea (OSA) patients with and without maxillomandibular deficiency, and to compare the changes in facial aesthetics after MMA between the two groups. MMA-treated patients who had both baseline and follow-up polysomnography (PSG) data and lateral cephalograms were enrolled in this retrospective study. In addition to PSG and cephalometric data, patient satisfaction with postoperative breathing and facial aesthetics, and overall satisfaction with the treatment were assessed.

Comparative analysis of the clinical and epidemiological characteristics of human influenza virus vs. human respiratory syncytial virus vs. human metapneumovirus infection in nine provinces of China during 2009‐2021

alexandrossfakianakis shared this article with you from Inoreader

ABSTRACT

Background

A comparative analysis of confirmed cases of human influenza virus (HIFV), human respiratory syncytial virus (HRSV) and human metapneumovirus (HMPV) was conducted to describe their clinical and epidemiological characteristics.

Methods

During 2009 to 2021, active surveillance of acute respiratory infections (ARIs) was performed in nine provinces of China. Clinical and epidemiological information and laboratory testing results of HIFV, HRSV, and HMPV were analyzed.

Results

Among 11,591 ARI patients, the single-infection rates of HIFV, HRSV, and HMPV were 15.00%, 9.59% and 2.24%, respectively; the coinfection rate of these three viruses was 0.64%. HIFV infection was mainly in adults aged 15–59 years, accounting for 39.10%. HRSV and HMPV infections were mainly in children under 5 years old, accounting for 87.13% and 83.46%, respectively. Patients with HRSV infection were younger than HMPV. HRSV and HMPV had high similarity in clinical m anifestations, presenting with lower respiratory symptoms. HIFV mainly presented with upper respiratory infection. The epidemic peak of HRSV was earlier than that of HIFV, and that of HMPV was later than those of HRSV and HFIV. A total of 85.14% of coinfection cases were children under 5 years old. Coinfection might increase the risk of pneumonia in HIFV cases. During 2020-2021, the positive rates and seasonal patterns of these three viruses changed due to the impact of the COVID-19 pandemic.

Conclusions

Certain clinical and epidemiological features were observed in HIFV, HRSV and HMPV infections, which could be benefit for guiding clinical diagnosis, treatment, and prevention of these three viruses in China.

Long-term Outcomes of Vocal Fold Paralysis Following Patent Ductus Arteriosus Ligation in Neonates

Premature infants undergoing patent ductus arteriosus ligation are at risk for vocal fold paralysis leading to long term voice and swallowing complications. In this study, we review risk factors for vocal fold paralysis and offer insight into long term outcomes and further treatment needs in this unique patient population.


Introduction

In patients undergoing patent ductus arteriosus (PDA) ligation there is a significant risk of left vocal fold paralysis (LVFP) particularly in premature neonates who are small for gestational age. The objective of this study is to determine the incidence of LVFP in infants following PDA ligation and report on long-term outcomes in patients with LVFP.

Methods

We performed a prospective study of patients undergoing PDA ligation in the newborn intensive care unit (NICU) between April 2004 and May 2014. Following PDA ligation, flexible laryngoscopy was performed to assess vocal fold mobility. Patients were then followed longitudinally to determine long-term outcomes.

Results

A total of 163 infants underwent PDA ligation. Thirty-six patients (22%) developed LVFP following the procedure. Twenty-five percent of neonates <1500 g experienced LVFP versus 5% of patients >1500 g (p = 0.033). Patients with LVFP were more likely to require a feeding tube (64% vs. 19.6%; p < 0.05) and spent more time in the NICU (135 days vs. 106 days; p < 0.05). Twenty-four patients received long-term follow-up. Six (25%) had complete resolution of LVFP, 10 (42%) were compensated, and 8 (33%) demonstrated persistent LVFP with no improvement.

Conclusions

The incidence of LVFP after PDA ligation is high especially in extremely low birth weight children. The majority of patients recovered well with time, but further surgical intervention was required in uncompensated cases. Long-term follow-up of these patients is needed to ensure improvement.

Development and validation of prognostic nomograms in patients with ascending type of nasopharyngeal carcinoma: A retrospective study based on SEER database

alexandrossfakianakis shared this article with you from Inoreader

Abstract

Background

Nomograms specifically used to predict the prognosis of ascending type nasopharyngeal carcinoma (NPC) have not been constructed.

Methods

Data of ascending type (T3-4N0-1M0) NPC from the Surveillance, Epidemiology, and End Results (SEER) database between 2004 and 2015 were extracted.

Results

Altogether 862 patients with ascending type NPC were enrolled, including 603 in training cohort and 259 in validation cohort. Age, marital status, pathology, grade, tumor size, T classification, and chemotherapy were the independent prognostic factors for overall survival (OS). Age, marital status, pathology, grade, and chemotherapy were the independent prognostic factors for cancer-specific survival (CSS). In training cohort, the concordance index of the OS and CSS nomograms were 0.694 (95% confidence interval [CI], 0.677–0.711) and 0.678 (95%CI, 0.659–0.697), respectively, while those in validation cohort were 0.740 (95%CI, 0.715–0.765) and 0.708 (95%CI, 0.679–0.737), separately.

Conclusion

The as-constructed nomograms for ascending type NPC could provide accurate prognostic predictions of OS and CSS.

Survival rates, patient satisfaction, and prosthetic complications of implant fixed complete dental prostheses: A 12‐month prospective study

alexandrossfakianakis shared this article with you from Inoreader

Abstract

Purpose

To determine the survival rate, incidence of prosthetic complications and patient satisfaction of implant fixed complete dental prostheses (IFCDPs) after a mean observation period of 1.4 years.

Materials and Methods

Twenty-eight (28) eligible participants were recruited according to specific inclusion and exclusion criteria. The definitive metal-acrylic resin IFCDPs consisted of titanium bars veneered with acrylic resin and acrylic denture teeth. Prosthodontic complications, divided into major and minor, were monitored. Parameters such as gender, jaw location, bruxism, and occlusal scheme were evaluated. Moreover, a questionnaire was administered throughout the study to assess patient satisfaction. Poisson regression as well as repeated measures ANOVA were used for statistical analysis.

Results

Fourteen (14) males and 14 females were enrolled and followed-up at 3, 6, and 12 months. All IFCDPs survived (100% survival rate). The most frequent minor complication was the loss of material used to close the screw access hole (20% out of total complications). The most frequent major complication was chipping of the acrylic denture teeth (77.14% out of total complications). Gender (P = 0.008) and bruxism (P = 0.030) were significant predictors for the total major complications (major wear and major chipping) while occlusal scheme was a significant predictor for major chipping events (P = 0.030).

Conclusions

While IFCDPs demonstrated high prosthetic survival rates, they also exhibited a high number of chipping events of the acrylic veneering material, especially in males, bruxers, and individuals with canine guidance occlusion. However, the occurrence of these prosthetic complications did not negatively affect patient satisfaction.

Middle Fossa Decompression for Recurrent Facial Palsy: Prevalence and Surgical Outcomes

Our study examined the facial nerve and audiometric outcomes of patients undergoing middle fossa decompression for recurrent facial nerve paresis. We found that facial nerve decompression for patients with incomplete functional recovery may be an effective treatment for decreasing the frequency and severity of facial palsy episodes.


Objective

To investigate the surgical outcomes in patients treated for recurrent facial nerve palsy (RFP) at a quaternary facial nerve referral center.

Methods

A retrospective chart review was performed on 132 patients with RFP who presented to our institution's facial nerve clinic from 2001 to 2021. Records were analyzed for etiology of palsy, facial nerve function, and recurrence rates. Pre- and post-operative audiometric outcomes were also assessed in surgically managed patients.

Results

6.8% of RFP patients underwent surgical decompression. For patients who did not undergo surgery, the House-Brackmann (HB) score was 2.9 ± 1.3 (SD) at the initial clinic visit, and 2.4 ± 1.3 (SD) at the last clinic visit. This difference was significantly different (p = 0.01, t-test). For surgical patients, the pre-operative HB score was 2.9 ± 0.9 (SD) and post-operative HB score was 1.8 ± 0.6 (SD), which were significantly different (p = 0.01, t-test). The number of facial palsy episodes also decreased pre- and post-operatively from 3.5 ± 0.8 (SD) to 0.2 ± 0.4 (SD) episodes, which were significantly different (p < 0,001, t-test). Audiometric outcomes were not significantly different pre- and post-surgery (p = 0.31, t-test for PTA; p = 0.34, t-test for WRS).

Conclusion

Facial nerve decompression for RFP patients with incomplete functional recovery may be an effective treatment for decreasing the frequency and severity of facial palsy episodes.
