SuP‐Ring: A pneumatic tactile display with substitutional representation of contact force components using normal indentation

xlomafota13 shared this article with you from Inoreader SuP‐Ring: A pneumatic tactile display with substitutional representation of contact force components using normal indentation Via The International Journal of Medical Robotics and Computer Assisted Surgery Abstract Background Shear force is important for tumor detection and can contribute to minimally invasive surgery (MIS). A popular method uses lateral skin stretch to produce shear force but has some limitations. Methods We have developed a ring-type pneumatic tactile display that employs normal indentation substituted for lateral skin stretch to represent normal and shear feedback, called SuP-Ring. Psychophysical experiments were conducted to evaluate how users perceive the provided feedback and the effectiveness of SuP-Ring in tumor localization. Results The experimental results show that the participants could perceive the provided normal and shear feedback well. Shear feedback enables users to enhance their performance in localizing the tumor and normal feedback could contribute to ensuring the safety requirements in MIS. Conclusions The proposed tactile display could be useful for intraoperative tumor localization and has the potential to be used in a wide variety of applications.

Incidental paratracheal air cyst in papillary thyroid cancer patient: a case report

xlomafota13 shared this article with you from Inoreader Incidental paratracheal air cyst in papillary thyroid cancer patient: a case report Via radioactive iodine Gland Surg. 2021 Jul;10(7):2334-2339. doi: 10.21037/gs-21-139. ABSTRACT Paratracheal air cyst (PTAC) is a collection of air in the right posterior side of the trachea with an uncertain etiology. We report a papillary thyroid cancer patient with a PTAC that was removed during thyroid cancer surgery. A 68-year-old woman was diagnosed with right papillary thyroid cancer with suspicion of central lymph node metastasis. She had a history of hypertension and a rear-end collision car acci dent 20 years prior. On computed tomography, an ovoid cyst was incidentally found in the paratracheal region at the thoracic inlet level. Emphysematous lung with an obstructive lung defect was noted without any symptoms. Bilateral total thyroidectomy with ipsilateral central compartment neck dissection was indicated for the patient. During surgery, removal of the cyst was inevitable for complete central neck dissection. Histopathologic analysis revealed an etiology of tracheal mucus sprouting through weak trachea points. No postoperative complications occurred. The patient continued on levothyroxine medication without further radioactive iodine therapy. After 6 months, follow-up ultrasound showed no evidence of recurrence. We hypothesized that obstructive lung disease with impaired lung function or trauma history might have contributed to the development of PTAC. Future studies are needed to determine if PTACs have any association with obstructive lung disease or trauma. PMID: 34422604 | PMC:PMC8340328 | DOI:10.21037/gs-21-139 View on the web Inoreader.

Comparison of the abilities of staging and risk stratification systems to predict the long-term structural recurrence in patients with differentiated thyroid carcinoma after total thyroidectomy and radioactive iodine remnant ablation

xlomafota13 shared this article with you from Inoreader Comparison of the abilities of staging and risk stratification systems to predict the long-term structural recurrence in patients with differentiated thyroid carcinoma after total thyroidectomy and radioactive iodine remnant ablation Via radioactive iodine Gland Surg. 2021 Jul;10(7):2200-2210. doi: 10.21037/gs-21-8. ABSTRACT BACKGROUND: In patients with differentiated thyroid carcinoma (DTC), various staging and risk stratification systems have been applied to estimate long-term recurrence, which is a major issue during the postoperative follow-up period. However, the efficacy of these systems remains unclear in this context. METHODS: The present historical cohort study included 510 patients with DTC who underwent a total thyro idectomy followed by radioactive iodine (RAI) remnant ablation. Enrolled patients were categorized according to the 8th edition of American Joint Committee on Cancer/Union for International Cancer Control (AJCC/UICC) Tumor Node Metastasis (TNM) staging system, the 2015 American Thyroid Association (ATA) initial risk stratification system, and the dynamic risk stratification (DRS) system. The ability of each system to predict long-term structural recurrence was compared using proportion of variance explained (PVE) by logistic regression models. RESULTS: The median follow-up period was 108 months. Structural recurrence occurred in 7.6% of the patients (n=39/510). Disease-free survival (DFS) curves of the patients within each category in the TNM staging system, the ATA initial risk stratification system, and the DRS system were significantly different (P<0.001). The PVE of the DRS system (20.7%) was higher than those of the TNM staging system and the ATA initial ris k estimates. CONCLUSIONS: The DRS system may effectively predict long-term structural recurrence and guide long-term management and follow-up strategies in patients with DTC undergoing total thyroidectomy and RAI remnant ablation.

Endonasal Free Flap Reconstruction Combined With Draf Frontal Sinusotomy for Complex Cerebrospinal Fluid Leak: A Technical Report & Case Series

xlomafota13 shared this article with you from Inoreader Endonasal Free Flap Reconstruction Combined With Draf Frontal Sinusotomy for Complex Cerebrospinal Fluid Leak: A Technical Report & Case Series Via leak of cerebrospinal fluid Oper Neurosurg (Hagerstown). 2021 Aug 23:opab309. doi: 10.1093/ons/opab309. Online ahead of print. ABSTRACT BACKGROUND: Frontal sinus cranialization with closure via bifrontal pericranial flaps is the gold standard for separating the nasofrontal recess from the intracranial cavity for posterior table defects. Despite the high success rate, cerebrospinal fluid (CSF) leak may persist and is particularly challenging when vascularized reconstructive options from the bicoronal incision are exhausted. OBJECTIVE: To assess a novel endonasal technique using an adipofascial radial forearm free flap delivered to the frontal recess through a Draf sinusotomy to repair complex CSF leaks from the frontal sinus. METHODS: A retrospective review of 3 patients (all male; ages 42, 43, and 69 yr) with persistent CSF leak despite frontal sinus cranialization and repair with bifrontal pericranium was performed. Etiology of injury was traumatic in 2 pat ients and iatrogenic in 1 patient after anaplastic meningioma treatment. To create space for the flap and repair the nasofrontal ducts, endoscopic Draf III (Case 1, 3) or Draf IIb left frontal sinusotomy (Case 2) was performed. The forearm flap was harvested, passed through a Caldwell-Luc exposure, and placed within the Draf frontal sinustomy. The flap vessels were tunneled to the left neck and anastomosed to the facial vessels by the mandibular notch. RESULTS: Intraoperatively, the flaps were well-seated and provided a watertight seal. Postoperative hospital courses were uncomplicated. There were no new CSF leaks or flap necrosis at 12, 14, and 16 mo. CONCLUSION: Endoscopic endonasal free flap reconstruction through a Draf procedure is a novel viable option for persistent CSF leak after failed frontal sinus cranialization.

Outcome of Eustachian Tube Balloon Dilation in Children: A Systematic Review

xlomafota13 shared this article with you from Inoreader Outcome of Eustachian Tube Balloon Dilation in Children: A Systematic Review Via otol rhinol Ann Otol Rhinol Laryngol. 2021 Aug 22:34894211041340. doi: 10.1177/00034894211041340. Online ahead of print. ABSTRACT OBJECTIVE: Eustachian tube dysfunction (ETD) is a chronic entity that has been historically managed with adenoidectomy and ventilation tube insertion. Recently, balloon dilation of the eustachian tube has shown promising results in recalcitrant eustachian tube dysfunction. We reviewed the literature to determine the outcome of eustachian tube balloon dilation in children. METHODS: A literature search was conducted for the period from 1990 to 2020 by searching several databases over a 1-month period (January 2021) according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and the Cochrane Handbook for Systematic Reviews for Interventions. Primary outcome was defined as the success of the intervention determined by the resolution of symptoms, and secondary outcome was determined by revisions surgery and presence of complications. RESULTS: Only 7 articles were identified based on our objectives and selection criteria. All studies included are retrospective cohort case series (Level IV) and 1 cohort of matched controls (Level III). A total of 284 patients were included in this review, with a mean age of 7.8 years. A total of 463 balloon dilation were performed either bilaterally or unilaterally. The most common finding of ETD is middle ear effusion in 5 studies. Balloon dilation of eustachian tube was second-line treatment in 6 studies and first-line treatment in 1 study. Improvement of symptoms was identified in all studies through various assessments performed. Revision surgery was performed in 1 study with no major complications reported. CONCLUSIONS: Balloon dilation of the eustachian tube may be considered as an alternative procedure following failed standard treatment in children. The quality of evidence is inadequate to recommend widespread use of the technique until a better-quality study has been completed. Future randomized controlled studies with a large sample size are warranted to determine the efficacy of this procedure amongst children.

xlomafota13 shared this article with you from Inoreader Use of 532 nm Potassium Titanyl Phosphate Laser on Vocal Fold Scars Under Topical Anesthesia: A Pilot Study Via otol rhinol Ann Otol Rhinol Laryngol. 2021 Aug 23:34894211041819. doi: 10.1177/00034894211041819. Online ahead of print. ABSTRACT OBJECTIVE: This pilot study aims to evaluate the efficacy of 532 nm potassium titanyl phosphate (KTP) laser under topical anesthesia in patients with vocal fold scars. METHODS: A series of 18 patients with vocal fold scars of varying degrees were treated. The KTP laser was used under local anesthesia in the outpatient clinic. It was set to deliver 6 W o f power using a continuous output mode. Close-to-contact mode was used for laser irradiation, and contact mode was used for ablation and excision of the lesions. Some of the patients received laser scar ablation on both vocal folds; the scarred vocal fold on one side and the hypertrophic vocal fold on the other. Parameters include glottic closure, amplitude, and mucosal wave pattern were measured using laryngeal stroboscopic examination. Aerodynamic and voice evaluations were carried out using maximum phonation time (MPT), jitter, shimmer, Voice Handicap Index questionnaire (VHI-30), and GRBAS scale. RESULTS: In total, 21 surgeries were performed on 18 patients. Glottic closure, amplitude, and mucosal wave pattern showed improvement 2 months postoperatively (P < .05). There was significant improvement in the postoperative scores for VHI-30, VHI-emotional sub-scale, VHI-physical sub-scale, and GRBAS (P < .05). There was no significant difference in the MPT a nd VHI-functional sub-scale before and after the operation (P > .05). Re-adhesion of the anterior commissure was observed in 2 patients with Type III scars. CONCLUSION: The 532 nm KTP laser is an effective tool for the treatment of vocal fold scars. Further research is required to determine if serial laser applications could improve outcomes for this challenging condition. LEVEL OF EVIDENCE: Level IV.

Online ahead of print. ABSTRACT OBJECTIVE: Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, can result in persistent loss of taste and smell. This study was performed to assess acoustic reflex threshold (ART) in patients with taste disorders caused by SARS-CoV-2. MATERIAL AND METHODS: This retrospective study enrolled 11 patients (9 men, 2 women; average age = 22.3 years) with a history of COVID-19 and had complaints of taste disorder and sensitivity to loud sounds. The control group consisted of 13 healthy participants (10 men, 3 women; average age = 23.4 years). Anamnesis, neuro-otological, ear, nose and throat, and eye examinations, as well as a taste test, pure tone audiometry, speech discrimination test, and impedance audiometry were performed in all participants. RESULTS: All participants in the study group had a negative taste test result. In addition, ART values were significantly higher in the study group than the control group at all frequencies. CONCLUSIONS: SARS-CoV-2 could be a neurotropic virus that can cause facial nerve neuropathy. PMID:34420420 | DOI:10.1177/01455613211039808 View on the web Inoreader.

Online ahead of print. ABSTRACT Granular cell tumor (GCT) is a rare benign soft tissue neoplasm that develops primarily in the skin and subcutaneous tissue of the head and neck, frequently in the tongue, but has not been observed in the auditory meatus. These tumors generally present as slow-growing nodules with few unique clinical or radiological features, and so must be confirmed by pathologic al examination. Here, we present the case of a 62-year-old female with right hearing loss and benign GCT in the right auditory meatus initially misdiagnosed as cholesteatoma.
