xlomafota13 shared this article with you from Inoreader

Oper Neurosurg (Hagerstown). 2022 Jan 1;22(1):e1-e6. doi: 10.1227/ONS.0000000000000013.

ABSTRACT

BACKGROUND: Advances in technique and instrumentation have improved outcomes after resection of anterior skull base tumors. However, cerebrospinal fluid (CSF) leak occurs in 4%-20% of patients. To reduce the risk of CSF leak, we have developed a novel reconstruction technique that consists of a 4-layered graft with patchwork suturing and hard material.

OBJECTIVE: To evaluate the effectiveness of this reconstruction technique when used for resection of anterior skull base tumors.

METHODS: This case series included 59 patients with anterior skull base tumors in whom the 4-layered closure technique was used. The main outcome measures were complications, including CSF leak, meningitis, postoperative bleeding, and infection.

RESULTS: There were no CSF leak cases or serious complications after closure of the anterior skull base using t he 4-layered technique.

CONCLUSION: Closure of the anterior skull base in 4 layers prevented CSF leak and was not associated with any serious complications. However, further studies in larger numbers of patients are needed to confirm our outcomes using this closure method.

Arch Clin Cases. 2021 Dec 29;8(4):72-83. doi: 10.22551/2021.33.0804.10190. eCollection 2021.

ABSTRACT

Iodine uptake and organification are the hallmarks of thyroid cells differentiation. The loss of these characteristics in thyroid cancer leads to radioactive iodine refractoriness, a rare condition that bears a low survival rate and poor prognosis. We present a 52-year-old patient presenting dry cough and dyspnea in the supine position. Imaging examinations revealed a thyroid nodul e with a high suspicion of malignancy in the right thyroid lobe, multiple laterocervical and mediastinal lymph nodes, lung, bone, and brain metastases. Fine needle aspiration cytologic features have advocated for papillary thyroid cancer (PTC). The patient underwent total thyroidectomy and selective lymphadenectomy. Subsequently, the patient received suppressive treatment with levothyroxine and four courses of radioactive iodine therapy. In addition, to treat bone and brain metastases, the patient experienced external radiotherapy and glucocorticoid therapy. Despite this rigorous therapeutic management, the patient obtained an incomplete structural and functional response. Although the last two posttherapeutic 131I whole-body scans were negative, the patient had elevated stimulated thyroglobulin levels and loco-regional recurrence by thyroid ultrasound. This aspect would suggest that thyroid cells become unable to uptake 131I, most likely through the emergence of new genetic mutations in the cancer cells. In conclusion, our patient's case suggests a 131I-refractory PTC, requiring the initiation of novel targeted systemic agents such as tyrosine kinase inhibitors, in order to improve structural and functional outcomes of radioactive iodine therapy and to afford prolonged progression-free survival advantage.

Ear Nose Throat J. 2022 Jan 5:1455613211069349. doi: 10.1177/01455613211069349. Online ahead of print.

ABSTRACT

Cutaneous metastases from squamous cell carcinomas of the head and neck region are uncommon, and their location at the nasal tip is exceptionally rare. A patient, previously treated with surgery and chemoradiation for a hypopharyngeal squamous cell carcinoma, developed several red nodular skin lesions at the nasal tip. Biopsy revealed cutaneous metastasis from the primary tumor. This manifestation was previously described as a "clown nose," given their appearance and location. Skin lesions should raise suspicion of malignancy, despite their location at uncommon places, particularly in patients with previous diagnosed cancer. Clinicians must be aware that metastases from head and neck cancer can present as a "clown nose."

Eustachian Tube Functions in Concurrent Chemoradiotherapy for Head and Neck Cancer Patients

xlomafota13 shared this article with you from Inoreader

Abstract

Ototoxicity is a dose-limiting adverse event for concurrent chemoradiotherapy (CCRT) with high-dose cisplatin for locally advanced head and neck squamous cell carcinoma (HNSCC). Both irradiation to the Eustachian tube (ET) and weight loss are risk factors for patulous ET. The aim of this prospective, observational study was to elucidate the incidences of patulous ET conditions before and after CCRT in HNSCC patients by means of ET function tests. This prospective, observational study was conducted in 27 HNSCC patients who received CCRT with high-dose cisplatin, and ET function tests (sonotubometry and tubo-tympano-aerodynamic graphy) were performed before and 3 months after CCRT. Factors potentially affecting the incidence of patulous ET conditions after CCRT were evaluated. Of the 54 ears from 27 patients investigated, patulous ET conditions were observed in 12 ears (22.2%) from 9 patients (33.3%) before CCRT and 15 ears (27.8%) from 11 patients (40.7%) at 3 months after CCRT. Only patulous ET conditions before CCRT in each ear were significantly associated with patulous ET conditions after CCRT (p = 0.010). This is the first report to describe the incidences of patulous ET conditions before and after CCRT in HNSCC patients. HNSCC patients are potentially at higher risk of patulous ET.

Clinicopathological Difference Between Gingivobuccal and Oral Tongue Cancers: A Cross-Sectional Observational Study from a Tertiary Healthcare Centre in Northern India

xlomafota13 shared this article with you from Inoreader

Abstract

Gingivobuccal and oral tongue squamous cell carcinomas are commonly considered together as a single clinical entity for staging and treatment purposes. Though there is data suggesting a significant difference between SCC of various oral cavity subsites, very few studies have compared clinicopathological characteristics between the tongue and gingivobuccal primaries. We retrospectively analysed 225 patients with biopsy-proven gingivobuccal (GB) and oral tongue (OT) SCC operated between April 1, 2018 and April 30, 2021 in All India Institute of Medical Sciences, Rishikesh, India to compare their clinicopathological characteristics. Demographic, clinical and histopathological data were collected from electronic medical records. An independent sample t-test was used to compare means and Pearson chi-square test or Fisher exact test was applied to compare the distribution of categorical variables. A relative male preponderance (12:1 vs. 5:1, p = 0.036) and increased smokeless tobacco consumption (82% Vs. 69%, p = 0.003) was seen in GB-SCC. Significantly higher proportion of patients with OT-SCC presented with early primaries (T1/T2) (54.1% vs. 24.8%, p < 0.001). Similarly, a higher proportion of GB-SCC patients presented with palpable neck nodes (cN +) (81% Vs. 67%, p = 0.02). Due to early primary tumours at presentation, stage I/II disease was also significantly higher in cases of OT-SCC (36.5% Vs.13.7%, p < 0.001). No difference was noticed in age at presentation, neck node status, and other clinicopathological parameters. GB-SCC has a higher male preponderance than OT-SCC due to relatively higher consumption of smokeless tobacco in males. Oral tongue cancers presented at an earlier stage than gingivobuccal malignancies. No difference in neck node status, however, suggests a relatively aggressive disease behaviour and early regional metastasis in tongue cancers. Follow up data regarding recurrence and survival is required to further characterise the differences between these two common OSCC subsites.

Dose Response. 2021 Dec 14;19(4):15593258211062775. doi: 10.1177/15593258211062775. eCollection 2021 Oct-Dec.

ABSTRACT

The role of Iodine-131 therapy is well established as an adjuvant therapy and for thyroid remnant ablation in differentiated thyroid cancer (DTC); however controversy still exists regarding its appropriate dose. Purpose of this study was to compare the effectiveness of low-dose and high-dose Iodine-131 ablation therapies in low- and intermediate-risk PTC patients. Eighty-four patients were divided equally into Group I: Ablated with high dose of Iodine-131 and Group II: Ablated with low dose of Iodine-131. Iodine-131 WBS, serum TG levels and USG neck of all patients were performed at first presentation, 6 months, 1 year, and 2 years follow up. Results are as follows: Group I: 64%, 72%, and 76% intermediate-risk patients were disease free at the follow up intervals of 6 months, 1 year, and 2 years, respectively. Similarly 70%, 82%, and 82% low-risk patients were disease free at above mentioned intervals. Group II: 56%, 60%, and 64% were disease free among intermediate-risk patients while percentage of disease free low-risk patients was 70%, 76%, and 76% at follow up intervals. Low dose of radioactive Iodine-131 was found as effective as high dose in thyroid remnant ablation of PTC patients.

J Surg Case Rep. 2021 Dec 24;2021(12):rjab578. doi: 10.1093/jscr/rjab578. eCollection 2021 Dec.

ABSTRACT

Ectopic thyroid tissue, 90% presenting in lingual zone, is often scanned by ultra-sonography or computed tomography. Most surgeons regard ectopic thyroid as metastatic foci from thyroid cancer, thus resection is recommended. Here, we reported a man with bilateral papillary thyroid cancer, accompany with normal ectopic thyroid tissue in right sternocleidomastoid muscle. In this c ase, we highlighted: (i) It is rarely reported that ectopic normal thyroid tissue presented in sternocleidomastoid muscle. (ii) The ectopic thyroid tissue may not always be metastatic foci even though bilateral thyroid tumors were confirmed to be papillary cancer. (iii) Contrary to radical excision of all ectopic thyroid tissue, we advocate that only patients who need to receive the radioactive iodine therapy after total thyroidectomy should remove the ectopic normal thyroid tissue.

xlomafota13 shared this article with you from Inoreader

Eur Arch Otorhinolaryngol. 2022 Jan 6. doi: 10.1007/s00405-021-07194-6. Online ahead of print.

ABSTRACT

PURPOSE: Obstructive sleep apnea (OSA) increases the risk for olfactory dysfunction. However, the relationship between olfactory function and cognition in OSA patients is unclear. The present study aimed to investigate the relationship between cognition and olfactory dysfunction (OD) in patients with OSA.

METHOD: This was a cross-sectional study in which 74 patients with OSA and 22 controls were recruited. All subjects completed polysomnography, Sniffin' Sticks, and -neurocognitive assessments. According to results of Sniffin' Sticks, OSA patients were divided into two groups: OSA with OD (53 cases) and OSA without OD (21 cases). Neurocognitive function was assessed by Montreal Cognitive Assessment (MoCA), Memory and Executive Screening (MES), and Shape Trail Test (STT). Cognition was compared between OSA with and without OD. C orrelation between olfactory parameters and respiratory sleep parameters and neurocognitive assessments was analyzed.

RESULTS: Compared with OSA without OD, OSA with OD showed significantly decreased neurocognitive scores of MoCA (29-27 vs 27-23, p < 0.01), MES-5R (45-40.1 vs 43-33.5, p < 0.01) and increased consuming time of STT-B (91.66 vs 121.63, p < 0.01). A positive correlation was found between the scores of MoCA and MES-5R and all olfactory parameters. In addition, a negative correlation was present between the time consumed for STT-B and odor thresholds (r = - 0.344, p < 0.01), odor identification (r = - 0.335, p < 0.01), and threshold-discrimination-identification scores (r = - 0.448, p < 0.01).

CONCLUSION: Olfactory function is associated cognitive function in patients with OSA and may provide a new direction for early treatment interventions in OSA patients at risk for cognitive impairment.
