Background: Oral cavity is the most prevalent site of head and neck squamous cell carcinomas (HNSCCs). Most often diagnosed at a locally advanced stage, treatment is multimodal with surgery as the cornerstone. The aim of this study was to explore the molecular landscape of a homogenous cohort of oral cavity squamous cell carcinomas (OCSCCs), and to assess the prognostic value of tumor mutational burden (TMB), along with classical molecular and clinical parameters.

Coronaviruses did not invite attention at a global level and responsiveness until the series of 2003-SARS contagion followed by year-2012 MERS plus, most recently, 2019-nCoV eruptions. SARS-CoV &MERS-CoV are painstaking, extremely pathogenic. Also, very evidently, both have been communicated from bats to palm-civets & dromedary camels and further transferred ultimately to humans.

Background noise makes listening effortful and may lead to fatigue. This may compromise classroom learning, especially for children with a non-native background. In the current study, we used pupillometry to investigate listening effort and fatigue during listening comprehension under typical (0 dB signal-to-noise ratio [SNR]) and favorable (+10 dB SNR) listening conditions in 63 Swedish primary school children (7-9 years of age) performing a narrative speech-picture verification task.

Fanconi anemia (FA) due to biallelic mutations in the BRCA2 gene is very rare and associated with an extremely high risk of early-onset of aggressive childhood malignancies, predominantly brain tumors, leukemia, and nephroblastoma. Here, we present a consanguineous family with three affected children of the D1 subtype of FA and describe the clinical consequences of the earliest known biallelic nonsense/stop-gain germ-line mutation in BRCA2, exon 5 c.469A>T, that leads to a premature stop of translation, p.

In vivo diffusion-weighted magnetic resonance imaging is limited in signal-to-noise-ratio (SNR) and acquisition time, which constrains spatial resolution to the macroscale regime. Ex vivo imaging, which allows for arbitrarily long scan times, is critical for exploring human brain structure in the mesoscale regime without loss of SNR. Standard head array coils designed for patients are sub-optimal for imaging ex vivo whole brain specimens. Read More

Introduction: Primary pleomorphic pulmonary angiosarcomas are extremely rare tumors which could be easily mistaken for pulmonary emboli.

Background And Findings: We describe the successful perioperative management of a patient with a pulmonary arterial mass which turned out to be a primary pulmonary angiosarcoma. The severe pulmonary hypertension was a particular challenge compounded with the site and adhesions of the tumor, and pulmonary hemorrhage. Read More

Reduced inflammation, increased insulin sensitivity, and protection against cancer are shared between humans and mice with GH/IGF1 deficiency. Beyond hormone levels, miRNAs are important regulators of metabolic changes associated with healthy aging. We hypothesized that GH deficiency in humans alters the abundance of circulating miRNAs and that a subset of those miRNAs may overlap with those found in GH-deficient mice. Read More

Introduction: Nasogastric tube (NGT) insertion is sometimes required in intubated patients. NGTs are prone to kink and coil during blind insertion. We hypothesized that Wire rope guide-assisted NGT insertion with chin lift can significantly improve the first-attempt success rate over the conventional technique during its insertion in intubated patients.

Background: Pancreatoduodenectomy is the only treatment with a promise of cure for patients with pancreatic head adenocarcinoma, and a negative resection margin is an important factor related to overall survival. Complete clearance of the medial margin with removal of the so-called mesopancreas may decrease the recurrence rate after pancreatic resection. Here, we present some important information about the mesopancreas, total mesopancreas excision, and technical aspects to achieve negative resection margins. Read More

Uncontrolled activation of the Hedgehog (Hh) signaling pathway, operating through GLI transcription factors, plays a central role in the pathogenesis of cutaneous basal cell carcinoma and contributes to the development of several malignancies arising in extracutaneous sites. We now report that K5-tTA;tetO-Gli2 bitransgenic mice develop distinctive epithelial tumors within their jaws. These tumors consist of large masses of highly proliferative, monomorphous, basaloid cells with scattered foci of keratinization and central necrosis, mimicking human basaloid squamous cell carcinoma (BSCC), an aggressive upper aerodigestive tract tumor.

Hemorrhage in recurrent and/or metastatic (R/M) head and neck squamous cell carcinoma (HNSCC) may be attributed to chemotherapy and local tumor irradiation. Evidence of the relationship between hemorrhage in R/M HNSCC and targeted therapies, including epidermal growth factor receptor (EGFR) and vascular endothelial growth factor (VEGF) inhibitors, or immune checkpoint inhibitors, is limited. We aimed to identify epidemiological and clinical data related to the occurrence of hemorrhage in R/M HNSCC and to explore its relationship with various therapies. Read More

Purpose: Pignat's partial laryngectomy with crico-hyoido-epiglotto-plasty (CHEPL) is a vertical laryngectomy with resection of the anterior portion of the thyroid cartilage and reconstruction with a wires net and the subhyoid muscles. The aim of this retrospective study was to evaluate and analyze oncologic and functional outcomes in patients affected by laryngeal squamous cell carcinoma and treated with Pignat's partial laryngectomy.

Methods: Seventy patients with cT1-cT3 glottic cancer were surgically treated with Pignat's technique. Read More

The diagnosis and treatment of head and neck cancer (HNC) can have substantial impact on swallowing function, nutritional balance, physical function and quality of life (QoL). Early initiated swallowing exercises are hypothesized to improve swallowing function in HNC patients. The aim was to investigate the effects of swallowing exercises and progressive resistance training (PRT) during radiotherapy on swallowing function, physical function and QoL in patients with pharynx-, larynx-, oral cavity cancer or unknown primary compared to usual care.

Purpose: P-glycoprotein (P-gp) function is altered in several brain disorders; thus, it is of interest to monitor the P-gp function in vivo using PET. (R)-[C]verapamil is considered the gold standard tracer to measure the P-gp function; however, it presents some drawbacks that limit its use. New P-gp tracers have been developed with improved properties, such as [F]MC225. Read More
