Cancer Risk Associated with Continuous Positive Airway Pressure: A National Study

paythelady.61 shared this article with you from Inoreader

Objective

In 2021 the U.S. FDA issued a Class 1 safety recall notice for specific devices due to a risk of carcinogen exposure. The objective of this study was to evaluate reports of cancer linked to CPAP devices to understand implications for the field of sleep medicine.

Methods

Cases of cancer involving CPAP devices were retrieved from the MAUDE database from 2014 to 2021 and analyzed with descriptive statistics.

Results

A total of 2571 patient injuries were associated with CPAP. Reports of cancer (n = 209; 4.62%) were the second most commonly documented patient problem associated with CPAP, although 1950 (43.13%) patients had a device problem without an associated injury. Of the 209 cancer cases associated with CPAP, 200 (95.7%) of the adverse event reports were received by the FDA in 2021. There were 174 (9.15%) descriptions of the CPAP polyurethane sound abatement foam degrading in association with a cancer diagnosis, but degradation was more commonly not associated with malignancy (n = 1728; 90.85%). Other frequently documented CPAP device problems included broken devices (n = 279; 6.92%), fire (n = 182; 4.51%), and patient–device incompatibility (n = 144; 3.57%).

Conclusion

Malignancy associated with CPAP devices has been reported; however, future studies are required to establish causation. Given 95.7% of those documented cases were reported in 2021, otolaryngologists should be prepared to discuss the risks of carcinogenesis associated with CPAP. The otolaryngology community should also be aware of the potential bandwagon effect and the implications for CPAP compliance.

Key Points on Functional Rhinoplasty Patient Evaluation

paythelady.61 shared this article with you from Inoreader

Abstract

Purpose of Review

The goal of this review is to discuss the key points in the evaluation of patients for functional nasal airway surgery to help optimize outcomes.

Recent Findings

Development of the clinical practice guideline for rhinoplasty was a recent effort to guide perioperative care and workup of patients undergoing rhinoplasty. This guideline highlighted the importance of patient reported outcome measures (PROMs) in evaluating surgical outcomes. There has also been an increase in publications regarding intervention in the pediatric population. Finally, there has been more work into the exact mechanics of nasal airway obstruction and lateral wall insufficiency.

Summary

Functional rhinoplasty lacks clear objective tests to help guide surgery. PROMs are important in evaluating surgical outcomes and advances in technology such as computational fluid dynamics, and virtual surgical planning will hopefully provide insight into airflow patterns and where surgical intervention should be focused to maximize patient outcomes.

Anatomical variations in the relationship between the spinal accessory nerve and internal jugular vein: a systematic review and meta-analysis

paythelady.61 shared this article with you from Inoreader
The relationship between the spinal accessory nerve and internal jugular vein is important for modified neck dissection surgery. Therefore, the aim of this review was to investigate variations in this relationship. Through a search of the PubMed, Scopus, Web of Science, LILACS, and SciELO databases, the review authors collected anatomical data for inclusion in a meta-analysis, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Four relationship patterns were identified and classified: type 1, the nerve lies superficial to the vein; type 2, the nerve lies deep to the vein; type 3, the nerve crosses the branches of the vein; type 4, the nerve splits and its branches pass around the vein.

Physiother Theory Pract. 2022 Mar 28:1-15. doi: 10.1080/09593985.2022.2056862. Online ahead of print.

ABSTRACT

OBJECTIVE: The aim was to investigate the effectiveness of Kinesio taping for lymphedema following head and neck cancer therapy and its effect on patient compliance and quality of life.

METHODS: A total of 66 patients with lymphedema following head and neck cancer therapy were randomly allocated to the therapeutic Kinesio taping group (n = 33) and the sham Kinesio taping group (n = 33). All participants received manual lymphatic drainage, Kinesio taping, and home exercises for the first four weeks, and only home exercises for the second four weeks. The tape measurements, a scale of external lymphedema, a scale of the internal ly mphedema, and quality of life were evaluated in both groups. The perceived discomfort consisting of limitation of daily living activities, pain, tightness, stiffness, and heaviness were also recorded.

RESULTS: When the group x time effect was evaluated, it was observed that external lymphedema was significantly reduced in both groups according to neck and face composite measurements (p < .001). However, in these measurements, a significant difference was found between the groups in favor of the KT group (p = .001, p = .032, respectively). At the end of the study, there was no significant difference in terms of internal lymphedema in both groups (p = .860). The quality of life parameters such as global health status and swallowing were significantly better in the Kinesio taping group (p < .001). There was no significant difference in the parameters of perceived discomfort between the two groups (p = .282, p = .225, p = .090, p = .155, p = .183, respectively).

CONCLU SION: Kinesio taping is effective in tape measurements and positively affects the quality of life in lymphedema following head and neck cancer therapy.

Surg Clin North Am. 2022 Apr;102(2):209-231. doi: 10.1016/j.suc.2022.01.001. Epub 2022 Mar 8.

ABSTRACT

In this section, we discuss the management of benign salivary gland disease. Pathologies vary from sialolithiasis, salivary duct stenosis, sialadenitis, infectious glandular disease, autoimmune glandular disease, and radioactive iodine-induced disease. We discuss both novel techniques in the diagnosis and management of these diseases, including ultrasound, sialendoscopy, minor salivary gland biopsy, and botulinum toxin injection, which allow for both the alleviation of symptoms and gland preservation.

Classification of superficial lymphatic pathways in the upper extremity and incidence of lymphatic obstruction according to the lymphatic pathways in patients with unilateral upper extremity lymphedema

a.sfakia shared this article with you from Inoreader

J Plast Reconstr Aesthet Surg. 2022 Mar 2:S1748-6815(22)00133-4. doi: 10.1016/j.bjps.2022.02.049. Online ahead of print.

ABSTRACT

BACKGROUND: Indocyanine green (ICG) lymphography is frequently used in the diagnosis of lymphedema, as well as the planning of its surgical management, but the typical anatomy of the superficial lymphatic pathways is incompletely delineated. This study aims to evaluate the topographical anatomy of superficial lymphatic vessels of the upper extremity METHODS: Sixty consecutive patients undergoing lymphaticovenular anastomosis for unilateral upper extremity lymphedema were selected. Lymphatic mapping was performed on the normal contralateral arm with ICG lymphography. A single upper arm reference line and two separate forearm reference lines (anterior and posterior) were drawn between anatomic landmarks. Lymphatic pathways were analyzed based on distances (cm) from the reference lines and were compared with th ose in lymphedema arms.

RESULTS: Mean age of the patients were 54.6 ± 8.4 years. Three lymphatic flow pathways were identified: anterior (100%), posterior (96.6%), and posterior-ulnar lymphatic (33.3%) vessels. The anterior and posterior lymphatic vessels ran along the anterior and posterior reference lines, respectively, on the forearm (within 2 cm) and medial to the upper arm reference line. In arms with lymphedema, the absence of lymphatic flow was most commonly observed in posterior lymphatics (29/59, 49%), followed by anterior (15/60, 25%) and posterior-ulnar lymphatics (1/20, 5%). Compared to normal arms, new lymphatic flow through posterior-ulnar lymphatics was observed in 34.5% of patients (10/29) in whom posterior lymphatics was completely obstructed.

CONCLUSIONS: Superficial lymphatic vessels can be classified into anterior, posterior, and posterior-ulnar lymphatic vessels. Posterior-ulnar lymphatic vessels might be least affected by lymphosclerosis in patient s with lymphedema.

Design and Experimental Validation of a Master Manipulator with Position and Posture Decoupling for Laparoscopic Surgical Robot

a.sfakia shared this article with you from Inoreader

Abstract

Background

The master manipulator with position and posture decoupling and force feedback can improve the immersion of the operation, and the gravity balance can reduce the fatigue of surgeons.

Methods

A seven degree of freedom master manipulator is developed. The parallelogram structure and the angle conversion method contribute to the realization of decoupling position and posture. The calculating method based on the virtual work principle is adopted to achieve the passive gravity balance. The relationship between the master manipulator's joint torque and output force is established to achieve force feedback.

Results

A prototype of the master manipulator was built and its performance was experimentally evaluated. The maximum value of the positioning mean absolute error is 1.2 mm. The maximum absolute error of the force-feedback is 0.32 N, respectively.

Conclusion

With the functions of positioning, gravity balance, and force feedback, our manipulator shows the potential for single port laparoscopic surgery.

ABSTRACT

Objective: To evaluate the curative effect of Potassium titanyl phosphate (KTP) laser and pingyangmycin injection for adult laryngeal hemangiomas (ALH). Methods: This was a retrospective study conducted on patients treated with either KTP laser or pingyangmycin injection to assess the efficacy of both treatment and compare the effects on different types of adult laryngeal hemangioma. Results: The ordinal logistic regression test showed the surgery methods had no effect on the therapeutic results. On the contrary, the shape of ALH and the interaction between surgical procedures and ALH shape affected the p rognosis of the ALH. This meant that the shape of ALH might be a confounding factor affecting the therapeutic effect of ALH. Thus, the Cochran-Mantel-Haenszel test which is a stratification analysis was used to assess the interaction between surgical procedures and ALH shape. Then better results were achieved using the KTP laser for the plane and raised types of ALH. Conclusions: The selection of surgical procedures (the KTP laser or pingyangmycin injection approaches) affects the treatment of ALH. For plane and raised ALH, the KTP laser may be recommended.

Migration of a Fish Bone From the Esophagus to the Thyroid Gland

a.sfakia shared this article with you from Inoreader

pubmed-meta-image.png

Ear Nose Throat J. 2022 Mar 29:1455613221086032. doi: 10.1177/01455613221086032. Online ahead of print.

ABSTRACT

Accidental swallowing of fish bone is one of the most common emergencies in the otolaryngology department. The impacted fish bones are usually found in the palatine tonsil, base of the tongue, valleculae, pyriform sinus, and esophagus, which can be successfully removed after a thorough examination. However, in some cases, the fish bone may penetrate into the neck soft tissue and migrate to extraluminal organs, causing infection, abscess formation, or rupture of vessels. In such cases, prompt recognition and immediate removal of the impacted fish bone are necessary. Herein, we report a rare case of a 60-year-old woman who had accidently swallowed a fish bone 10 days prior to visiting the outpatient department. The fiberoptic scope and head and neck computed tomography scans were obtained from the outpatient department. The fish bone was found to migrate from the upper esophagus to the left thyroid gland. First, a rigid esophageal endoscopy was performed in the operating room, but no obvious fish bone was noted over the esophagus. Finally, the fish bone was removed via exploratory cervicotomy with left-sided total lobectomy of the thyroid. The patient recovered after the operation, and there were no further complications during the 3 years of follow-up.

A model to predict a risk of allergic rhinitis based on mitochondrial DNA copy number

a.sfakia shared this article with you from Inoreader

Eur Arch Otorhinolaryngol. 2022 Mar 29. doi: 10.1007/s00405-022-07341-7. Online ahead of print.

ABSTRACT

PURPOSE: To determine whether mitochondrial DNA copy number (mtDNA-CN) is associated with allergic rhinitis (AR), and further establish a nomogram model for the early diagnosis of AR.

METHODS: We carried out a case-control study involving a total of 134 subjects, including 66 healthy controls and 68 AR patients. The mtDNA-CN in peripheral blood of all subjects was detected by real-time fluorescence quantitative polymerase chain reaction, and general information of patients was recorded. And, least absolute shrinkage selection operator (LASSO) regression was used to screen clinically significant variables, which were substituted into a logistic regression analysis to determine independent risk factors. Next, a nomogram model was developed for the risk prediction of AR. Then, internal validation was performed with the bootstrap resampling. Ultimately, the clinical benefit and validity of the nomogram were assessed by receiver operating characteristic (ROC) curve, bias-corrected curve, and decision curve analysis (DCA).

RESULTS: MtDNA-CN and total IgE were determined as independent risk factors of AR. The final model achieved an area under the ROC curve (AUC) of 0.869, and the DCA curve demonstrated that the nomogram was clinically beneficial for practical application.

CONCLUSION: An increase of the mtDNA-CN was linked to the occurrence risk of AR. The nomogram prediction model based on mtDNA-CN showed the potential clinical utility in improving risk prediction and providing new insights for exploring the pathogenesis of AR.
