Online ahead of print. ABSTRACT PURPOSE: Auricular pseudocyst (AP) is a benign, noninflammatory swelling to the ear, located on either the front or side surface. Deroofing surgery with variable compression methods is considered the most effective method. However, post-operative wound pain is the main drawback following compression. We are introducing a novel painless surgical procedure which involves deroofing technique followed by Merocel® compression dressing. METHODS: From 2015 to 2020, thirty-one patients with AP received this new surgical compression method in our university-affiliated tertiary hospital. Retrospective chart review and the analysis of the results were conducted. RESULTS: All patients had unilateral lesions, with left side lesions (58.1%) predominant. The concha cymba (38.7%) and concha cavum (35.8%) were the most common sites. Pre vious aspiration or drainage had been performed for the cysts in eight patients (25.8%). Only one patient had the recurrence after post-operative 3 months and received the revised surgery without following recurrence and discomfort. Among all patients, 29 (93.5%) patients claimed minimal pain around 0 or 1 in numeric rating scale of pain score. Three patients had mild ecchymosis but recovered after conservative treatment. One patient had mild auricular deformity after surgery due to pre-treatment partial cartilage necrosis. All patients had follow-up for at least 6 months. CONCLUSION: This novel Merocel® compression dressing technique to treat AP after deroofing is an effective procedure. Minimal pain, simple to do and easily acquired materials were the advantages of this novel procedure. PMID:34704136 | DOI:10.1007/s00405-021-07152-2 View on the web Inoreader.

HPV‐Positive Status Is an Independent Factor Associated With Sinonasal Inverted Papilloma Recurrence

xlomafota13 shared this article with you from Inoreader HPV‐Positive Status Is an Independent Factor Associated With Sinonasal Inverted Papilloma Recurrence Via The Laryngoscope Abstract Objectives The present study aimed to evaluate human papillomavirus (HPV) occurrence in sinonasal inverted papilloma (SNIP), and to assess factors associated with HPV positivity and SNIP recurrence. Study Design Prospective study. Methods We prospectively collected clinical data and fresh tissue specimens from 90 consecutive patients treated for SNIP at Helsinki University Hospital, between 2015 and 2019. Fourteen patients with recurrent SNIP underwent repeated tumor sampling. All tissue specimens were analyzed for the presence of HPV. Factors associated with SNIP recurrence and HPV positivity were assessed. Results Among 107 SNIP specimens, 14 (13.1%) were positive for low-risk HPV and 6 (5.6%) were positive for high-risk HPV. HPV positivity was associated with an increased risk of recurrence (P = .004). Smoking was significantly associated with HPV positivity in SNIP (P = .01), but a history of HPV-related diseases or patient sexual habits did not correlate with HPV positivity. The recurrence rate was lower among patients with SNIP that underwent an attachment-oriented resection, compared to patients treated without attachment-oriented resections (78.6% vs 25.8%, P < .001). Conclusions The risk of SNIP recurrence was highly associated with 1) HPV positivity and 2) surgery without an attachment-oriented resection. Oncogenic HPV was rare in SNIP.

Evolution of Voice Quality in Type 1–2 Transoral CO2 Laser Cordectomy: A Prospective Comparative Study

xlomafota13 shared this article with you from Inoreader Evolution of Voice Quality in Type 1–2 Transoral CO2 Laser Cordectomy: A Prospective Comparative Study Via The Laryngoscope Abstract Objectives/Hypothesis To compare the 12-month evolution of voice quality outcomes in patients who benefited from types 1–2 transoral CO2 laser cordectomy (TLC) for an early-stage vocal fold squamous cell carcinoma (VFSCC). Study Design Prospective uncontrolled study. Methods Sixty patients with cT1 VFSCC were consecutively recruited from a single medical center. Thirty patients benefited from type 1 TLC, while type 2 TCL was performed in 30 patients. The following voice quality outcomes were evaluated at baseline, 3-, 6-, and 12-month post-TLC: voice handicap index (VHI), GRBAS, speech rate, maximum phonation time (MPT), and acoustic parameters. Voice quality evolution was compared between type 1 and type 2 TLC. Results Fifty-seven patients completed the evaluations. Type 1 TLC patients reported significant improvements of VHI, grade of dysphonia, and breathiness at 3-, 6-, and 12-month post-TLC. Speech rate and jitter values improved 6- and 12-month post-TLC. A few voice quality outcomes reported 3- or 6-month post-TLC improvements in type 2 TLC group, while VHI, grade of dysphonia improved at 6- and 12-month post-TLC. MPT significantly decreased at 6- and 12-month post-TLC, while there were no acoustic measurement changes in type 2 TLC. Conclusions The effect of TLC on voice quality may depend on the type of TLC. Type 1 TLC was associated with faster voice quality improvements compared with type 2 TLC. VHI and dysphonia grade were identified as the most relevant tool of voice changes irrespective to the TLC type. Level of Evidence 3 Laryngoscope, 2021 View on the web Inoreader.

Severe Versus Very Severe Pediatric Obstructive Sleep Apnea Outcomes After Adenotonsillectomy

xlomafota13 shared this article with you from Inoreader Severe Versus Very Severe Pediatric Obstructive Sleep Apnea Outcomes After Adenotonsillectomy Via The Laryngoscope Objectives/Hypothesis Adenotonsillectomy (AT) is generally considered the first line treatment for pediatric patients with obstructive sleep apnea (OSA). Pediatric patients with severe OSA have worse outcomes after AT than patients with milder OSA. It is currently unclear if this group of higher morbidity patients should be subdivided further. This study investigates patients with severe pediatric OSA to determine if there are differences in postsurgical outcomes based on initial severity of sleep disordered breathing, medical comorbidities, or demographic factors. Study Design Retrospective cohort study at a single tertiary referral center. Methods Patients aged 2–18 who underwent polysomnogram (PSG) from October 2012 to January 2019, had an apnea-hypopnea index (AHI) >10, and subsequently underwent AT were identified using a filter through electronic medical record. A total of 112 patients underwent both pre- and postoperative PSG. Bivariate analysis was conducted via Pearson chi-square test. Univariate and multivariate analyses via binary logistic and multinomial linear regressions were performed using SPSS. Results Of the 112 patients included in this study, 68 patients were identified as having severe OSA (AHI = 10–20) and 44 as having very severe OSA (AHI > 20). Very severe OSA patients were significantly less likely to be cured of sleep disordered breathing or have their OSA reduced to mild OSA. Obese patients were found to have less reduction in AHI after AT. Conclusions The postsurgical outcomes of patients with severe and very severe OSA are significantly different indicating that patients traditionally categorized as having severe OSA may need to be further subcategorized.

Transcriptomic profiling of recessive dystrophic epidermolysis bullosa wounded skin highlights drug repurposing opportunities to improve wound healing

xlomafota13 shared this article with you from Inoreader Transcriptomic profiling of recessive dystrophic epidermolysis bullosa wounded skin highlights drug repurposing opportunities to improve wound healing Via Experimental Dermatology Abstract Chronic wounds present a major disease burden in people with recessive dystrophic epidermolysis bullosa (RDEB), an inherited blistering skin disorder caused by mutations in COL7A1 encoding type VII collagen, the major component of anchoring fibrils at the dermal-epidermal junction. Treatment of RDEB wounds is mostly symptomatic and there is considerable unmet need in trying to improve and accelerate wound healing. In this study, we defined transcriptomic profiles and gene pathways in RDEB wounds and compared these to intact skin in RDEB and healthy control subjects. We then used a reverse transcriptomics approach to discover drugs or compounds which might restore RDEB wound profiles towards intact skin. Differential expression analysis identified >2000 differences between RDEB wounds and intact skin, with RDEB wounds displaying aberrant cytokine-cytokine interactions, Toll-like receptor signalling, and JAK-STAT signalling pathways. In silico prediction for compoun ds that reverse gene expression signatures highlighted methotrexate as a leading candidate. Overall, this study provides insight into the molecular profiles of RDEB wounds and underscores the possible clinical value of reverse transcriptomics data analysis in RDEB, and the potential of this approach in discovering or repurposing drugs for other diseases.

Investigation of miR‐126‐3p loaded on adipose stem cell‐derived exosomes for wound healing of full‐thickness skin defects

xlomafota13 shared this article with you from Inoreader Investigation of miR‐126‐3p loaded on adipose stem cell‐derived exosomes for wound healing of full‐thickness skin defects Via Experimental Dermatology Abstract Objective To investigate the function of miR-126-3p loaded on adipose stem cell (ADSC)-derived exosomes (ADSC-Exos) in wound healing of full-thickness skin defects. Methods ADSCs transfected with miR-126-3p mimic, miR-126-3p inhibitor or pcDNA3.1-PIK3R2, or PKH26-marked ADSC-Exos were cultured with fibroblasts or human umbilical vein endothelial cells (HUVECs). The proliferation and migration rates of fibroblasts and angiogenesis of HUVECs were measured. Rats with full-thickness skin defects were injected with ADSC-Exos or exosomes extracted from ADSCs transfected with miR-126-3p inhibitor and the wound healing rates were measured. The wound bed, collagen deposition and angiogenesis in injured rats were assessed. Results ADSC-Exos could be ingested by fibroblasts and HUVECs. Co-incubation with ADSCs or ADSC-Exos promoted the proliferation and migration of fibroblasts and angiogenesis of HUVECs, which was further enhanced by miR-126-3p overexpression. Inhibition of ADSC-Exos or miR-126-3p or PIK3R2 overexpression suppressed the proliferation and migration of fibroblasts and angiogenesis of HUVECs. ADSC-derived exosomal miR-126-3p increased wound healing rate, collagen deposition and newly formed vessels in injured rats. Conclusion ADSC-derived exosomal miR-126-3p promotes wound healing of full-thickness skin defects by targeting PIK3R2. View on the web Inoreader. Take back control of your news feed.

xlomafota13 shared this article with you from Inoreader Revision surgery for chronically discharging mastoid cavities: mastoid obliteration with canal wall reconstruction versus non-obliteration surgery Via http://link.springer.com/journal/405,European archives of oto-rhino-laryngology,The European Federation of Oto-Rhino-Laryngological Societies (EUFOS) : affiliated with the German Society for Oto-Rhino Eur Arch Otorhinolaryngol. 2021 Oct 27. doi: 10.1007/s00405-021-07138-0. Online ahead of print. ABSTRACT PURPOSE: To evaluate the surgical results of revision canal wall down (CWD) surgery for chronically discharging mastoid cavities and to compare the non-obliteration approach to mastoid obliteration with canal wall reconstruction. METHODS: This is a retrospective cohort study. All adult patients (≥ 18 years) who underwent revision surgery for chronically draining mastoid cavities between January 2013 and January 2020 were included. Primary outcome measures included the dry ear rate, complications and postoperative hearing. RESULTS: 79 ears were included; 56 ears received revision CWD with mastoid obliteration and posterior canal wall reconstruction and 23 ears received CWD without mastoid obliteration. The dry ear rate at the most recent outpatient clinic visit (median 28.0 months postoperative) was significantly higher in the obliteration group with 96.4% compared to 73.9% for the non-obliteration group (p = .002). There were no differences in audiological outcome and incidence of complications between the two techniques. CONCLUSION: We show that in our study population revision CWD surgery with mastoid obliteration and posterior canal wall reconstruction is superior to revision CWD surgery without mastoid obliteration in the management of chronically discharging mastoid cavities. In the obliteration group, a dry ear was achieved in 96.4% as this was 73.9% in the non-obliteration group. We found no differences in audiological outcome and in incidence of complications between the two techniques. PMID:34705081 | DOI:10.1007/s00405-021-07138-0 View on the web Inoreader.

Med Oral Patol Oral Cir Bucal. 2021 Oct 27:24708. doi: 10.4317/medoral.24708. Online ahead of print. ABSTRACT BACKGROUND: Kaposi's sarcoma (KS) is an uncommon, multifocal and angioproliferative lesion, which demonstrates a poor prognosis. The aim of the present research was to explore the association of HIV viral load, CD4+ and CD8+ counts and the CD4+/CD8+ ratio on the risk of oral Kaposi's sarcoma (KS) development. MATERIAL AND METHODS: A total of 62 patients were retrieved from March 2008 to October 2020 from the files of two oral pathology centres. Clinical, laboratory and follow-up data were retrieved from their medical files. Poisson regression was used to explore the role of history of immunosuppression and its association with oral KS development. A P-value <0.05 was considered significant. RESULTS: Sixty-two patients were included in the present study (32 with oral KS and 30 with no presentation of lesions anywh ere on the body). Patients with oral KS presented a mean age of 32.6 years, and male patients were more affected. The hard palate (15 cases; 46.8%) was the main anatomical site affected. The lesions were mostly presented as swellings (13 cases; 40.6%) and nodules (12 cases; 37.5%). Systemic manifestations were also observed, including candidiasis (4 cases; 12.5%), bacterial infection (3 cases; 9.3%), tuberculosis (3 cases; 9.3%), herpes simplex (3 cases; 9.3%) and pneumonia (3 cases; 9.3%). A significant correlation was observed between HIV viral load, CD4+ count and the CD4+/CD8+ ratio with oral KS development. CONCLUSIONS: HIV viral load, CD4+ count and the CD4+/CD8+ ratio are associated with oral KS development. PMID:347 04977 | DOI:10.4317/medoral.24708 View on the web Inoreader.

Med Oral Patol Oral Cir Bucal. 2021 Oct 27:24980. doi: 10.4317/medoral.24980. Online ahead of print. ABSTRACT BACKGROUND: Data regarding the inter- and intraobserver variability in the radiological assessment of sialolithiasis using cone beam computed tomography are missing in the current literature. This study assessed the inter- and intraobserver variability in the radiological assessment of sialolithiasis using cone beam computed tomography (CBCT). MATERIAL AND METHODS: In 107 patients, 130 salivary glands (65 parotid and 65 submandibular) with clinical signs of obstruction were assessed by four independent observers; 2 residents OMFS and 2 experienced OMFS. The observers analyzed the CBCT images and determined the absence or presence of one or more salivary stones in the affected gland. This procedure was repeated after three months. RESULTS: Interobserver agreements showed kappa values of 0.84 for the parotid gland, an d 0.93 for the submandibular gland. Intraobserver agreements for the whole group reported kappa values between 0.83 - 0.95. There was no significant difference between residents and experienced OMFS. CONCLUSIONS: Due to the good inter- and intraobserver agreement, CBCT appears to be a reproducible imaging modality for detecting salivary stones in patients with signs and symptoms of obstructed parotid and submandibular glands.

Is periapical surgery follow-up with only two-dimensional radiographs reliable? A retrospective cohort type sensitivity study

xlomafota13 shared this article with you from Inoreader Is periapical surgery follow-up with only two-dimensional radiographs reliable? A retrospective cohort type sensitivity study Via pubmed: "med oral patol oral... Med Oral Patol Oral Cir Bucal. 2021 Oct 27:24447. doi: 10.4317/medoral.24447. Online ahead of print. ABSTRACT BACKGROUND: Two-dimensional (2D) radiographic techniques are commonly used for assessing lesion prognosis after endodontic surgery. The present retrospective cohort study analyzes the sensitivity and ability of different radiographic techniques in obtaining area and volume measurements of periapical lesions. MATERIAL AND METHODS: Preoperative and follow-up (6-48 months) periapical and panoramic radiographs (index test) and cone-beam computed tomography (CBCT) images (reference standard) were selected from an endodontic microsurgery database. Sensitivity was analyzed independently by two examiners. The areas of the 2D radiographic images and CBCT volumes were studied using Itk-Snap software and Romexis viewer. RESULTS: The sample comprised 105 patients and 105 teeth, with a mean follow-up of 21 months (range 6-48). P reoperatively, CBCT detected all the periapical areas, periapical radiography detected 67, and panoramic radiography detected 60. Postoperatively, of the 52 cases in which CBCT detected remains of the periapical area, periapical radiography detected 22, and panoramic radiography detected 17. The measurements of the areas obtained by the 2D methods, and the volumes obtained by CBCT, had to be transformed into linear measures for comparison purposes. The measurements were found to be significantly different in both the preoperative and the follow-up images. CONCLUSIONS: Periapical radiography showed greater sensitivity than panoramic radiography, both preoperatively and at follow-up. The lesions measured with CBCT were larger, with significant differences than as evidenced by the periapical and panoramic radiographs.
