Postparotidectomy sialocele: A 6‐year review of underlying factors

xlomafota13 shared this article with you from Inoreader Postparotidectomy sialocele: A 6‐year review of underlying factors Via Head & Neck Abstract Background Postparotidectomy sialocele is a frustrating challenge. Published rates of postparotidectomy fluid collections range from 6% to 39%. We report our experience of 398 parotidectomies performed over a 6-year period. Methods A retrospective chart review of parotidectomies performed over a 6-year period was completed. Drain placement, smoking status, tumor size, and postoperative utilization of scopolamine were analyzed. Binary logistical regression and odds ratio calculations were performed. Results Postparotidectomy sialocele occurred in 25% of patients. Neither suction drain placement nor usage of immediate postoperative scopolamine (in a 22-patient subset) prevented sialocele formation. Smoking status also did not correlate. Increasing resection size was linearly correlated with the risk of sialocele. Conclusion Drain placement and smoking status do not correlate with sialocele prevention after parotidectomy. Sialocele formation directly correlates with the resection size. These data may guide preoperative counseling; however, additional work is necessary to identify effective prevention mechanisms for postparotidectomy sialocele. View on the web Inoreader.

The role of fungus in the pathogenesis of chronic rhinosinusitis

xlomafota13 shared this article with you from Inoreader The role of fungus in the pathogenesis of chronic rhinosinusitis Via Current Opinion in Otolaryngology & Head and Neck Surgery - Current Issue Purpose of review The etiologic role of fungi in chronic rhinosinusitis remains controversial. The purpose of this review is to further our understanding of molecular immunologic pathways activated by fungi and clinical trials of antifungals in severe subtypes of asthma and allergic fungal rhinosinusitis. Recent findings Various fungal components such as protease and chitin are capable of eliciting a type 2 innate and adaptive immune response. However, definitive studies on the etiologic role of fungi in chronic rhinosinusitis (CRS) is dependent on the development of a fungi-induced murine model of CRS. Short of this model, extrapolations of observations and results from clinical trials in fungi-induced asthma subtypes support a key role of fungi in the pathophysiology of allergic fungal rhinosinusitis and possibly other CRS endotypes. Summary Fungi plays a key role in the pathophysiology of several subtypes of chronic inflammatory respiratory diseases. However, a fungi-induced murine model of CRS is needed to explicitly investigate the molecular pathways and potential therapeutic targets. View on the web Inoreader.

The role of nasopharyngectomy in the management of nasopharyngeal carcinoma

xlomafota13 shared this article with you from Inoreader The role of nasopharyngectomy in the management of nasopharyngeal carcinoma Via Current Opinion in Otolaryngology & Head and Neck Surgery - Current Issue Purpose of review Recently, endoscopic nasopharyngectomy (ENPG) has become an effective treatment for locally recurrent nasopharyngeal carcinoma (NPC). This article reviews recent publications on ENPG and specifically addresses the surgical anatomy of the nasopharynx and discusses several important issues regarding ENPG. Recent findings The surgical techniques for ENPG have been previously described in several studies. The latest published data revealed good outcomes of ENPG compared with intensity-modulated radiation therapy (IMRT) in recurrent NPC. In addition, ENPG avoids severe reirradiation side effects. This review highlights the surgical anatomy of ENPG, which is important in preventing possible serious complications. Summary ENPG is a good option for managing recurrent NPC. Careful preoperative evaluation and a full understanding of the surgical anatomy help in preventing damage to nearby critical neurovascular structure. Long-term follow-up is still needed to evaluate its eventual morbidity and efficacy. View on the web Inoreader. Take back control of your news feed. Follow us on Twitter and Facebook.

Emerging concepts in sinonasal tumor research

xlomafota13 shared this article with you from Inoreader Emerging concepts in sinonasal tumor research Via Current Opinion in Otolaryngology & Head and Neck Surgery - Current Issue Purpose of review Sinonasal malignancies are rare and understudied, often diagnosed at late stages, and may behave aggressively. This review explores investigative diagnostic, therapeutic, and scientific advances specific to sinonasal undifferentiated carcinoma (SNUC), intestinal-type adenocarcinoma (ITAC), and olfactory neuroblastoma (ONB). Recent findings A number of studies have recently contributed more robust knowledge of the genetic and molecular landscapes of SNUC, ITAC, and ONB. These analyses have identified SMARCB1 and IDH2 mutations in SNUC, potentially allowing for the tumor's subdivision. Recent studies have also defined a role for induction chemotherapy in SNUC. Somatic mutations for ITAC have been identified and may be potentially targetable with FDA approved therapies. Studies defining the tumor microenvironment for ITAC and ONB have introduced the possibility of immune checkpoint inhibition for these tumor types. Summary Studies reviewed here detail promising results of the most current and novel characterization of SNUC, ITAC, and ONB genetic and molecular landscapes, which have informed ongoing therapeutic discovery. With continued multi-institutional efforts, the field of sinonasal tumor research will achieve higher disease control and improved treatment outcomes for patients afflicted with these rare cancers.

Nail-based reconstruction strategies for Wassel-Flatt type IVh thumb polydactyly with a floating ulnar digit: A preliminary report with 63 thumbs

xlomafota13 shared this article with you from Inoreader Nail-based reconstruction strategies for Wassel-Flatt type IVh thumb polydactyly with a floating ulnar digit: A preliminary report with 63 thumbs Via Journal of plastic, reconstructive & aesthetic surgery : JPRAS J Plast Reconstr Aesthet Surg. 2021 Nov 30:S1748-6815(21)00617-3. doi: 10.1016/j.bjps.2021.11.071. Online ahead of print. ABSTRACT PURPOSE: To present a surgical regimen based on nail morphology for Wassel-Flatt type IVh thumb polydactyly with a floating ulnar digit. METHODS: Cases within six years were retrospectively analyzed and followed up for an average of 18 months. Three types of classifications were defined based on nail morphology ‒ ulnar nail dominant type with two subtypes of nail lateral fold symmetric or asymmetric, radial nail dominant type, and equal nail size type. One out of three procedures, on-top plasty (Ⅰ), soft tissue augmentation (Ⅱ), and the combination of the above two (Ⅲ), was performed. The Tada scoring system was used to evaluate the results. RESULTS: Sixty-three thumbs were enrolled, forty-one of better ulnar nail type underwent top transposition, and in cases of asymmetric nail lateral fold subtype, the result of procedure Ⅲ was better than that of procedure Ⅰ, thirteen of the radial nail dominant type and nine of equal nail size type both had procedure Ⅱ. The equal nail size type was the least effective among groups, with an average Tada of four points. Six cases underwent secondary revision surgery. According to the Tada scoring system, the results were excellent in 61, fair in two. CONCLUSIONS: Classifications based on the morphology of the nail can guide surgical planning. On-top plasty is suitable for symmetric nail lateral fold subtype. Soft tissue augmentation is ideal for radial nail dominant type and equal nail size type, and the combination of the two procedures is a better option for asymmetric nail lateral fold subtype.

Flap survival and functional outcomes in elbow soft tissue reconstruction: A 25-year systematic review

xlomafota13 shared this article with you from Inoreader Flap survival and functional outcomes in elbow soft tissue reconstruction: A 25-year systematic review Via Journal of plastic, reconstructive & aesthetic surgery : JPRAS J Plast Reconstr Aesthet Surg. 2021 Dec 2:S1748-6815(21)00637-9. doi: 10.1016/j.bjps.2021.11.091. Online ahead of print. ABSTRACT INTRODUCTION: Different elbow flap reconstructions have been described in the literature. We aim to define the optimal flap technique based on defect size and etiology. METHODS: A systematic review was undertaken using the terms "(Elbow reconstruction) AND ((Soft tissue) OR (flap))". Flaps were grouped under fasciocutaneous (FCF), muscular (MF), distant pedicled (DPF), and free flaps (FF). The primary outcome was flap survival. The secondary outcomes were postoperative complications and range of motion (pROM). RESULTS: Twenty articles with 224 patients were included. Defect sizes were small (<10 cm2) (18%), medium (10-30 cm2) (23%), large (30-100 cm2) (43%), and massive (>100 cm2) (16%). Etiologies included trauma (26%), burn contractures (26%), i nfection (26%), hardware coverage (16%), and others (6%). FCF (54%) was the preferred flap followed by MF (28%), DPF (13%), and FF (5%). The rate of flap necrosis was 4% and that of other complications was 10%. The postoperative range of motion (pROM) (reported in 154 patients) was >100°, 50-100°, and <50° in 82%, 17%, and 1% of the cases, respectively. Small defects were most commonly reconstructed with MFs (83%), medium defects were reconstructed with MFs (52%) or FCFs (46%), and large defects were reconstructed with FCFs (91%). Massive defects predominantly required DPFs (60%) and FFs (26%). FCFs were the most common reconstruction method for burn contractures (84%), infections (55%), and traumatic defects (51%). Hardware coverage was predominantly performed using MFs (86%). No difference in complications and pROM was found between flap techniques. CONCLUSION: Elbow flap reconstruction can be performed using different techniques. FCFs are the most commonly used rec onstruction method. MFs are useful for smaller defects and hardware coverage. DPFs and FFs are needed for massive injuries. PMID:34961697 | DOI:10.1016/j.bjps.2021.11.091 View on the web Inoreader. Take back control of your news feed. Follow us on Twitter and Facebook.

Patients with mild cognitive impairment diagnosed at dementia clinic display decreased maximum occlusal force: a cross-sectional study

xlomafota13 shared this article with you from Inoreader Patients with mild cognitive impairment diagnosed at dementia clinic display decreased maximum occlusal force: a cross-sectional study Via swallowing exercises BMC Oral Health. 2021 Dec 27;21(1):665. doi: 10.1186/s12903-021-02027-8. ABSTRACT BACKGROUND: Previous research indicates that patients with mild cognitive impairment (MCI) are more likely to have poor oral health and impairments in oral functions, which may be due to few remaining teeth and impaired tongue and lip motor function. However, the oral health of those patients following comprehensive cognitive assessment by a dementia specialist has not been sufficiently investigated. Therefore, this study aimed to clarify the oral function of patients with MCI and the association between oral health and lower cognitive function. METHODS: This cross-sectional study included 96 participants (men: 35; women: 61; mean age: 73.3 ± 8.5 years) who visited a dementia clinic between December 2017 and January 2020. Participants' cognitive function was assessed by a dementia specialist using neuropsychological and hematological tests and neuroimaging immediately after enrollment. The participants were divided into the healthy and MCI groups according to comprehensive cognitive assessment. Participants' age, sex, body mass index, primary disease, education level, drinking habits, smoking habits, living environment, employment status, and exercise habits were evaluated. Moreover, oral outcomes, including the number of existing teeth, number of functional teeth (natural and prosthetic teeth which were occluded with antagonists), denture use, oral dryness, tongue and li p motor function, tongue pressure, occlusal force, masticatory ability, and swallowing ability were recorded. The Mann-Whitney U test, χ2, and Fisher's exact tests were used for between-group comparisons. Furthermore, logistic regression analysis using MCI diagnosis as the target variable was performed. RESULTS: A comprehensive evaluation of the cognitive function of the study participants by the dementia specialist revealed that 48 participants (mean age: 69.8 ± 8.8 years) were healthy and 48 (mean age: 76.9 ± 6.7 years) had MCI. MCI participants were significantly older (p < 0.001) and had significantly fewer existing teeth (p = 0.031) and lower maximum occlusal force (p = 0.019) than healthy participants. Age (odds ratio: 1.126, p = 0.002) and maximum occlusal force (odds ratio: 0.978, p = 0.048) were significantly associated with lower cognitive function. CONCLUSIONS: Patients with MCI had poorer oral health than healthy individuals. Decreased maximu m occlusal force was independently associated with lower cognitive function, even when adjusted for age and sex.

Reversible Iodine Capture by Nonporous Adaptive Crystals of a Bipyridine Cage

xlomafota13 shared this article with you from Inoreader Reversible Iodine Capture by Nonporous Adaptive Crystals of a Bipyridine Cage Via radioactive iodine J Am Chem Soc. 2021 Dec 28. doi: 10.1021/jacs.1c11731. Online ahead of print. ABSTRACT The ability to capture radioactive iodine species is crucial for nuclear accident preparedness and nuclear waste treatment; however, it remains a challenge. Here we report a new readily obtainable nitrogen-rich nonporous cage (BPy-Cage) based on bipyridine building blocks that supports iodine capture. This cage is able to capture not only volatile iodine in vapor form but also iodine disso lved in various organic solvents or aqueous media with an iodine uptake capacity of up to 3.23 g g-1. The iodine within the cage (I2@BPy-Cage) can be released quickly upon immersing the bound solid form in DMF, allowing for control over acylation reactions. The cage solids reported here could be reused several times without substantial loss in their iodine capture performance. The effectiveness of the present system is ascribed to its ability to support strong iodine-bipyridine nitrogen lone pair interactions.
