ABSTRACT

OBJECTIVE: The relationship between ankyloglossia and speech is controversial. The objective of this study was to determine the effect of tongue-tie release on speech articulation and intelligibility.

METHODS: A prospective cohort study was conducted. Pediatric patients (>2 years of age) being referred for speech concerns due to ankyloglossia were assesse d by a pediatric otolaryngologist, and speech articulation was formally assessed by a speech language pathologist using the Goldman-Fristoe Test of Articulation 2 (GFTA-2). Patients then underwent a tongue-tie release procedure in clinic. After 1 month, speech articulation was reassessed with GFTA-2. Audio-recordings of sessions were evaluated by independent reviewers to assess speech intelligibility before and after tongue-tie release.

RESULTS: Twenty-five participants were included (mean age 3.7 years; 20 boys). The most common speech errors identified were phonological substitutions (80%) and gliding errors (56%). Seven children (28%) had abnormal lingual-alveolar and interdental sounds. Most speech sound errors (87.9%) were age/developmentally appropriate. GFTA-2 standard scores before and after tongue-tie release were 85.61 (SD 9.75) and 87.54 (SD 10.21), respectively, (P=.5). Mean intelligibility scores before and after tongue-tie release were 3.15 (SD .22) and 3.21 (SD .31), respectively, (P=.43).

CONCLUSION: The majority of children being referred for speech concerns thought to be due to ankyloglossia had age-appropriate speech errors at presentation. Ankyloglossia was not associated with isolated tongue mobility related speech articulation errors in a consistent manner, and there was no benefit of tongue-tie release in improving speech articulation or intelligibility.

Objective This study aimed to improve age-independent risk stratification for patients undergoing endoscopic transnasal transsphenoidal (TNTS) approach to pituitary mass resection by investigating the associations between frailty, American Society of Anesthesiologists (ASA), and comorbidity scores with severe complications following TNTS. Design This study is a retrospective review. Setting This review was conducted utilizing the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database. Participants A total of 680 cases of TNTS identified from 2010 to 2013 were included in this study. Main Outcome Measures The modified frailty index (mFI) was calculated to quantify frailty. ASA and Charlson's comorbidity index (CCI) scores were obtained as physiologic status and comorbidity-based prognostic markers. Severe complications were separated into intensive care unit (ICU)-level complications, defined by Clavien–Dindo grade IV (CDIV) criteria, and mortality. Results Overall, 24 CDIV complications (3.5%) and 6 deaths (0.9%) were recorded. Scores for mFI (p = 0.01, R 2 = 0.97) and ASA (p = 0.04., R 2 = 0.87) were significantly correlated with CDIV complications. ASA scores were significantly correlated with mortality (p = 0.03, R 2 = 0.87), as well as independently associated with CDIV complication by multivariable regression models (odds ratio [OR] = 2.96, 95% confidence interval [CI]: 1.35–6.83, p < 0.01), while mFI was not. CCI was not significantly associated with CDIV complications or mortality. A multivariable regression model incorporating ASA had a lower Akaike's Information Criteria (AIC; 188.55) than a model incorporating mFI (195.99). Conclusion Frailty and physiologic status, as measured by mFI and ASA scores respectively, both correlate with ICU-level complications after TNTS. ASA scores demonstrate greater clinical utility than mFI scores; however, as they are more easily generated, uniquely correlated with mortality and independently associated with ICU-level complication risk on multivariable regression analysis.

pubmed-meta-image.png

Endocrinol Metab (Seoul). 2021 Dec 16. doi: 10.3803/EnM.2021.1251. Online ahead of print.

ABSTRACT

BACKGROUND: The detrimental effects of excessive thyroid hormone on glucose metabolism have been widely investigated. However, the risk of diabetes in patients with long-standing hyperthyroidism, especially according to treatment modality, remains uncertain, with few longitudinal studies.

METHODS: The risk of diabetes in patients with Graves' disease treated with antithyroid dru gs (ATDs) for longer than the conventional duration (≥2 years) was compared with that in age-and sex-matched controls. The risk was further compared according to subsequent treatment modalities after a 24-month course of ATD: continuation of ATD (ATD group) vs. radioactive iodine ablation (RIA) group.

RESULTS: A total of 4,593 patients were included. Diabetes was diagnosed in 751 (16.3%) patients over a follow-up of 7.3 years. The hazard ratio (HR) for diabetes, after adjusting for various known risk factors, was 1.18 (95% confidence interval [CI], 1.10 to 1.28) in patients with hyperthyroidism. Among the treatment modality groups, the RIA group (n=102) had a higher risk of diabetes than the ATD group (n=4,491) with HR of 1.56 (95% CI, 1.01 to 2.42). Further, the risk of diabetes increased with an increase in the ATD treatment duration (P for trend=0.019).

CONCLUSION: The risk of diabetes was significantly higher in patients with long-standing Graves' disease than in t he general population, especially in patients who underwent RIA and prolonged ATD treatment. Special attention to hyperglycemia during follow-up along with effective control of hyperthyroidism may be necessary to reduce the risk of diabetes in these patients.

Thyroid Cancer Incidence Trends

xlomafota13 shared this article with you from Inoreader

Objective

To analyze thyroid cancer incidence trends among Filipinos relative to non-Filipino Asians and non-Hispanic Whites in the US.

Study Design

Population-based analysis of cancer incidence data.

Methods

Population-based analysis of cancer incidence data from Surveillance, Epidemiology, and End Results 9 detailed Asian/Pacific Islander subgroup incidence and population datasets. Adult patients aged 20 and older with thyroid cancer diagnosed in 2004 to 2014 were included. Annual percent change (APC) of the incidence rates were calculated using joinpoint regression analysis.

Results

The incidence rates were 19.57 (95% CI 19.03–20.12) per 100,000 for Filipinos, 10.45 (95% CI 10.22–10.68) per 100,000 for non-Filipino Asians, and 13.94 (95% CI 13.85–14.02) per 100,000 for non-Hispanic Whites. The highest increase was seen among non-Hispanic Whites (average APC 5.04, 95% CI 4.61–5.46). Incidence rates of tumors ≤ 2 cm remained stable among Filipinos but increased in non-Filipino Asians (average APC 5.38, 95% CI 2.51–8.34) and non-Hispanic Whites (average APC 5.81 95% CI 4.52–7.11).

Conclusion

Filipinos have high incidence of thyroid cancer compared with other racial/ethnic groups. However, non-Hispanic Whites have the highest increase in incidence rates, resulting in a significant narrowing of the gap in incidence rates between Filipinos and non-Hispanic Whites. This is most likely due to enhanced detection of small tumors in non-Hispanic Whites. Laryngoscope, 2021

Concomitant Variants in NF1, LZTR1, and GNAZ Genes Probably Contribute to the Aggressiveness of Plexiform Neurofibroma and Warrant Treatment with MEK Inhibitor

xlomafota13 shared this article with you from Inoreader

Abstract

Neurofibromatosis 1 (NF1) is caused by germline mutations in the NF1 gene and manifests as proliferation of various tissues, including plexiform neurofibromas. The plexiform neurofibroma phenotype varies from indolent to locally aggressive, suggesting contributions of other modifiers in addition to somatic loss of NF1. Here, we investigated a life-threatening plexiform neurofibroma in a 9-month-old female infant with NF1. Germline mutations in two Rasopathy-associated genes were identified using whole exome sequencing - a de-novo pathogenic variant in the NF1 gene, and a known pathogenic variant in the LZTR1 gene. Somatic analysis of the plexiform neurofibroma revealed NF1 loss of heterozygosity and a variant in GNAZ, a gene encoding a G Protein Coupled Receptor. Cells expressing mutant GNAZ exhibited increased ERK 1,2 activation compared to those expressing wild type GNAZ. Taken together, we suggest the variants in NF1, LZRT1, and GNAZ act synergistically in our patient, leading to MAPK pathway activation and contributing to the severity of the patient's plexiform neurofibromatosis. After treatment with the MEK inhibitor, trametinib, a prominent clinical improvement was observed in this patient. This case study contributes to the knowledge of germline and somatic non-NF1 variants affecting the NF1 clinical phenotype and supports use of personalized, targeted therapy.

Ear Nose Throat J. 2021 Dec 14:1455613211065510. doi: 10.1177/01455613211065510. Online ahead of print.

ABSTRACT

Middle ear tumors are relatively rare, and among them, the diagnoses of middle ear lesions originating from cartilage-like tissue are even rarer. Use of transcanal endoscopic ear surgery (TEES) has increased in recent years because of its advantages, such as clear visual field and minimally invasive procedure. Here, we report a middle ear mass originating from car tilage-like tissue treated with TEES. A 62-year-old woman presented with progressive right-sided hearing loss. A white mass was revealed through the tympanic membrane, and pure-tone audiometry detected a mean 50.0 dB conductive hearing loss. Computed tomography showed a mass in the tympanic cavity. TEES was performed for diagnosis and treatment. A white translucent tumor was observed intraoperatively, and it was completely resected. Histopathological examination confirmed the diagnosis of a mass originating from degenerated cartilage-like tissue. To the best of our knowledge, this is the first study of a middle ear mass originating from cartilage-like tissue treated with TEES. TEES with its clear visual field and precise techniques was beneficial in treating the middle ear lesions circumscribed in the tympanic cavity.

pubmed-meta-image.png

Curr Oncol. 2021 Nov 9;28(6):4577-4586. doi: 10.3390/curroncol28060387.

ABSTRACT

Cervical cancer is the fourth most common cancer in females worldwide. Patients with stage III and IV cervical cancer based on the Federation of Gynecology and Obstetrics (FIGO) classification have higher recurrence rates. Because of organs at risk (OAR) protection and the low indication rate of salvage surgery, the choice of treatment is always challenging. Systemic chemotherapy is palliative and can be performed in conjunction with surgery or radiotherapy; however, it has no significant benefit to survival. Brachytherapy and stereotactic body radiotherapy (SBRT) are characterized by extremely high radiation doses applied to tumor cells while sparing the normal tissues. Several studies have investigated the efficacy of these technologies in recurrent cervical cancer and showed promising results. The immune checkpoint inhibitors approach was also investigated and showed promising results too. Herein, we report a case of a patient with cervical cancer that recurred five months after adjuvant chemotherapy and concurrent chemoradiotherapy. The disease prognosis after interstitial implantation brachytherapy (IIB) was determined. Then, the patient underwent radioactive 125I-seed implantation combined with PD-1 inhibitor treatment. The patient exhibited a partial response after seed implantation, and up to now, the duration of this partial response was 24 months.

Chromophobe renal cell carcinoma-like thyroid carcinoma: possible misdiagnosis as metastatic renal cell carcinoma

xlomafota13 shared this article with you from Inoreader

Int J Clin Exp Pathol. 2021 Nov 15;14(11):1095-1101. eCollection 2021.

ABSTRACT

To date, multiple thyroid cancer variants have been reported. Herein, we report a rare case of chromophobe renal cell carcinoma-like thyroid carcinoma (CRETHCA) in a 60-year-old woman, for which the morphologic findings resembled those of chromophobe renal cell carcinoma (ChRCC). ChRCC of the kidney is characterized by large polygonal tumor cells with distinct cell borders, perinuclear clearing, multiple binucleate cells, and strongly positive immunostaining for paired box gene 8 (PAX8) and carbonic anhydrase IX (CA IX). In our case, the thyroid gland tumor was incidentally detected by routine medical screening without sufficient medical information; it showed similar histology and immunohistochemical features to ChRCC and was initially misdiagnosed as metastatic ChRCC. Additional tests, including kidney computed tomography and positron emission tomography, revealed no abnormalities in the patient's kidney; therefore, we diagnosed the tumor as CRETHCA. Focal weak staining for thyroid transcription factor 1 (TTF-1) was the only supporting evidence that it was a primary thyroid neoplasm. To the best of our knowledge, this is the second report of CRETHCA in literature. This novel variant is very difficult to distinguish from metastatic ChRCC and can be a diagnostic challenge for pathologists. Further studies of similar cases should be done to define this new entity.

Mucosal Epithelial Preservation of Free Nasal Grafts Depending on the Recipient Site

xlomafota13 shared this article with you from Inoreader

Objectives/Hypothesis

Reconstruction of mucosal defects using free mucosal grafts has become a common procedure during endoscopic sinus surgery. Epithelialization of mucosal grafts affects postoperative complications and outcomes, which could be influenced by different recipient tissue. However, morphological changes occurring in the grafts transplanted over different tissues remain unexplored.

Study Design

An animal study.

Methods

Free mucoperichondrial grafts were prepared from the nasal septum of rabbits; the cartilage group had reconstruction on the nasal septal cartilage, and the perichondrium group had reconstruction on the contralateral perichondrium. The nasal septum was removed after 1 and 4 weeks of reconstruction, and the graft was histologically evaluated.

Results

After 1 week of reconstruction, the mucosal epithelium of grafts in the cartilage group disappeared, whereas the columnar epithelium of grafts was preserved in the perichondrium group. After 4 weeks of reconstruction, the mucosal defect site was covered with mucosal epithelium in both groups. However, while squamous epithelium was mostly observed in the cartilage group, columnar epithelium containing the healthy ciliary and goblet cells was observed in the perichondrium group. Statistically significant differences were detected in the parameters of epithelial morphology between the two groups, which were higher in the perichondrium group.

Conclusions

In the reconstruction of mucosal defects using free mucosal grafts, difference in recipient tissue affects the graft epithelial morphology.
