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 Anatomical variations in the relationship between the spinal accessory nerve and internal jugular vein: a systematic review and meta-analysis Via International Journal of Oral and Maxillofacial Surgery 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.

Fibrin immobilization vestibular extension (FIVE): A case series

paythelady.61 shared this article with you from Inoreader Fibrin immobilization vestibular extension (FIVE): A case series Via Clinical Implant Dentistry and Related Research Abstract Aims The objective of the present case series is to report on the rationale, surgical technique and outcome of a protocol for peri-implant mucosal phenotype modification therapy, referred to as "fibrin immobilization vestibular extension (FIVE)". Material and Methods The protocol utilized entailed apical positioning and stabilization of peri-implant flap with modular screws. The screws were also used for the immobilization of solid matrix platelet-rich fibrin to fill the gap created between apically positioned flap and the crestal margin of the flap. Results A total of 30 patients (12 male, 18 females) with 93 implants were treated with FIVE protocol for various indications, including for vestibular extension following alveolar ridge augmentation (N = 6), preprosthetic (N = 9), postprosthetic (N = 2), and peri-implantitis (N = 13). The keratinized mucosal width preoperatively was 1.67 mm with 95% confidence interval [CI] (1.46, 1.88). Immediately following FIVE surgery, the vestibule was extended to 9.10 with 95% CI (8.44, 9.76). At 3 months, 4.9 mm (95% CI: 4.5–5.2 mm) of peri-implant keratinized mucosal width was present. The keratinized mucosal width remained relatively stable thereafter and was 4.0 mm (95% CI: 3.5–4.5 mm) at 3 years post-FIVE surgery. When overall group means across all time points were analyzed, maxilla had mean of 6.1 mm (95% CI: 5.8–6.5) versus mandible exhibited mean of 5.1 mm (95% CI: 4.6–5.6 mm). The mean of maxilla was si gnificantly higher than that of the mandible (p < 0.0001) across all time points. Treatment of peri-implantitis with FIVE lead to significant pocket reduction and wide band of keratinized mucosa. Seven of 38 implants in 3 of 13 peri-implantitis patients were removed due to advanced peri-implantitis. Discussion The present case series provides proof-of-principle data for efficacy of FIVE for peri-implant phenotype modification therapy that generated attached keratinized mucosa in a variety of applications. This protocol provides an alternative to procedures involving harvesting of autogenous mucosal graft. View on the web Inoreader. Take back control of your news feed.

a.sfakia shared this article with you from Inoreader The efficacy of Kinesio taping on lymphedema following head and neck cancer therapy: a randomized, double blind, sham-controlled trial Via swallowing exercises 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.

Management of Benign Salivary Gland Conditions

a.sfakia shared this article with you from Inoreader Management of Benign Salivary Gland Conditions Via radioactive iodine 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.

Natural history, predictive factors of apparent disease (structural or biochemical) and spontaneous excellent response in patients with papillary thyroid carcinoma and indeterminate response to initial therapy with radioiodine

a.sfakia shared this article with you from Inoreader Natural history, predictive factors of apparent disease (structural or biochemical) and spontaneous excellent response in patients with papillary thyroid carcinoma and indeterminate response to initial therapy with radioiodine Via radioactive iodine Endocrine. 2022 Mar 28. doi: 10.1007/s12020-022-03040-9. Online ahead of print. ABSTRACT BACKGROUND: About 20% of patients with papillary thyroid carcinoma (PTC) submitted to total thyroidectomy followed by radioactive iodine (RAI) exhibit an indeterminate response to therapy. The aim was to evaluate the natural history, predictive factors of apparent disease (structural or biochemical), and spontaneous excellent response in patients with PTC and an initial indeterminate response to RAI therapy defined based on unstimulated Tg (u-Tg). METHODS: We evaluated 164 patients who were initially treated with total thyroidectomy and RAI and who had an indeterminate response to therapy (u-Tg between 0.2 and 1 ng/ml, undetectable anti-Tg antibodies [TgAb], and neck ultrasonography [US] without anomalies). None of the patients received empirical therapy with RAI. The patients were followed up for 24 to 144 months (median 72 months). RESULTS: Apparent disease occurred in 16 patients (9.7%), including 13 with structural disease and 3 with u-Tg elevation > 1 ng/ml, but no tumor was detected by the imaging methods (biochemical disease). A higher frequency of disease was observed in patients with >3 lymph node metastases (LNM) and initial u-Tg >0.35 ng/ml. The frequency was only 2% among patients with ≤3 LNM and u-Tg ≤0.35 ng/ml and 9.7% among patients with > 3 LNM or u-Tg >0.35 ng/ml, while the frequency was 27% in patients with >3 LNM and u-Tg >0.35 ng/ml. In the absence of any additional therapy, u-Tg was <0.2 ng/ml (excellent response) in the last assessment in 70 patients (42.7%). Only initial u-Tg was associated with a higher probability of spontaneously achieving an excellent response: 40/72 patients (55.5%) with u-Tg ≤0.35 ng/ml versus 30/92 patients (32.6%) with u-Tg >0.35 ng/ml. CONCLUSIONS: A minority of patients with PTC and an initial indeterminate response to RAI defined based on u-Tg develop apparent disease (structural or biochemical) and many spontaneously achieve an excellent response. The risk of disease can be refined based on parameters such as the extent of lymph node involvement and initial Tg concentration.

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 Design and Experimental Validation of a Master Manipulator with Position and Posture Decoupling for Laparoscopic Surgical Robot Via The International Journal of Medical Robotics and Computer Assisted Surgery 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. This article is protected by copyright.

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

a.sfakia shared this article with you from Inoreader Migration of a Fish Bone From the Esophagus to the Thyroid Gland Via ear nose throat 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. PMID:35348022 | DOI:10.1177/01455613221086032 View on the web Inoreader.
