Methods: This is a retrospective observational study, using data from Electronic Health Records between 2017 and 2021.

Combined Stellate Ganglion Blockade and Epidural Thoracic Anesthesia for the Management of Ventricular Storm: A Case Report.

The term "ventricular storm (VS)" is defined as the occurrence of two or more separate episodes of ventricular tachycardia or fibrillation (VT/VF) or three or more appropriate discharges of an implantable cardioverter defibrillator for VT/VF during a 24-h period. A patient in his early 40s was observed in the emergency department of our hospital and was admitted to the cardiac intensive care unit due to multiple episodes of VT. This led to the need for deep sedation with orotracheal intubation and mechanical ventilation.

Patients with Spondylodiscitis following Chemoradiotherapy for Head and Neck Cancer in a Portuguese Cancer Hospital: A Case Report.

Introduction: Head and neck cancer is an umbrella term for tumor manifestations across the head and neck regions, including the oral cavity, pharynx (including the naso, oro, and hypopharynx), larynx, and sinuses. Treatment options for head and neck cancer include surgery, radiation therapy, chemotherapy, and immunotherapy, with specific treatment plans depending upon individual tumor location and staging, together with overall patient health status. Furthermore, definitive chemoradiotherapy (CRT) has emerged as a highly effective therapeutic option for locoregional advanced head and neck squamous cell cancer.

Alternative Extraction and Downstream Purification Processes for Anthocyanins.

Anthocyanins are natural pigments displaying different attractive colors ranging from red, violet, to blue. These pigments present health benefits that increased their use in food, nutraceuticals, and the cosmetic industry. However, anthocyanins are mainly extracted through conventional methods that are time-consuming and involve the use of organic solvents.

Does Octreoscan add value in the differential diagnosis of parapharyngeal space lesions?

Objective: We sought to evaluate the added value of complementary functional imaging in the differential diagnosis of parapharyngeal space lesions, as well as the benefit of performing a structured evaluation of diagnostic cross-sectional examinations.

Materials And Methods: This was a retrospective study of 16 patients with parapharyngeal space lesions who were referred to our facility following a cross-sectional imaging study listing head and neck paraganglioma as a possible diagnosis. Each patient underwent somatostatin receptor scintigraphy withIn-pentetreotide (Octreoscan) prior to surgical resection of the lesion.

Invasive aspergillosis of the skull base in an immunocompetent patient: a diagnostic challenge.

We describe the case of a 32-year-old man from Cape Verde having headache and increasing visual loss. Clinical and radiological investigations disclosed a massive destructive lesion involving the anterior and central skull base, orbit and nasoethmoid region initially interpreted as a malignant small round cell tumour. Surgical biopsies were negative for neoplasm, showing an intense inflammatory infiltrate together with fungus, later characterised as spp.

Calvarial tuberculosis in a paediatric patient: a diagnosis not to forget.

We report the case of a 10-year-old boy that presented with a palpable, painless, frontal lesion. Laboratory assessments were unremarkable and the patient was asymptomatic. Initial investigation, with a skull radiograph and unenhanced CT scan, showed a lytic midline frontal lesion involving the inner and outer tables of the skull and a large subgaleal hypodense component.

Ghost cell odontogenic carcinoma of the left maxilla.

We report the case of a 25-year-old man with a maxillary ghost cell odontogenic carcinoma (GCOC). The patient presented to the maxillofacial and head and neck surgery clinic with a growing lump in the left maxilla. Initial workup with CT revealed a cystic lesion in the left upper jaw with associated bone erosion and an enhancing soft-tissue component.

Chemoradiation induced multiple sclerosis-like demyelination.

We report the case of a 28-year-old man, diagnosed with a non-secreting, non-metastatic suprasellar germinoma treated with chemoradiation who developed, four months after completion of radiation therapy, multiple discrete demyelinating lesions mimicking multiple sclerosis (MS). The patient had no previous diagnosis of MS and the neuroimaging studies performed both at the time of diagnosis and after chemotherapy, pre-irradiation, showed no evidence of white matter lesions. He remained asymptomatic, with no focal neurological deficits.

Localised laryngotracheal amyloidosis: a differential diagnosis not to forget.

We present a case of multifocal laryngotracheal amyloidosis (LTA) in a 43-year-old man with persistent and progressive dysphonia and dyspnoea, and a first inconclusive histology. Although laryngeal amyloidosis accounts for fewer than 1% of all benign laryngeal tumours, it is in fact the most common site of amyloid deposition in the head, neck and respiratory tract. The clinical scenario is non-specific and diagnosis depends on a high degree of suspicion and on histology.

Solitary neurofibroma of the larynx: a diagnostic challenge.

Solitary neurofibromas of the larynx are extremely rare, with a total of 15 cases described in the literature. Nonetheless, acquaintance with this diagnosis is important, as misdiagnoses can have negative consequences. Presenting symptoms are non-specific and depend on tumour size and location.

Paediatric desmoid tumour of the head and neck: a complete response to chemotherapy and the paradigm shift towards non-surgical management.

Desmoid tumours are rare locally aggressive mesenchymal tumours with a high local recurrence rate, particularly in the head and neck locations. We present the case of a 5-year-old child with a locally invasive inoperable desmoid tumour of the masticator space who underwent a low-dose chemotherapy regimen for 17 months, obtaining a long-term complete response. Definitive evidenced-based treatment guidelines are lacking.

Mucinous cystadenocarcinoma of the oral tongue: malignant transformation from a mucinous cystadenoma?

Mucinous cystadenocarcinoma of minor salivary glands is an extremely rare entity that has only recently been described, with a few published cases in the English literature. A 42-year-old woman with a history of a surgically excised mucinous cystadenoma of the oral tongue, presented with a painful swelling in the oral tongue slowly growing for 1 month. On clinical examination, there was a firm, relatively well-circumscribed mass in the left posterior border of the mobile tongue.

Solid Lipid Nanoparticles as Carriers of Natural Phenolic Compounds.

Phenolic compounds are one of the most widespread classes of compounds in nature, with several beneficial biological effects being associated with their anti-oxidant and anti-carcinogenic activities. Their application in the prevention or treatment of numerous chronic diseases have been studied, but a major drawback is still the low bioavailability of these compounds, as well as their instability towards pH, temperature, and light in some cases. Nanotechnology has emerged as an alternative to overcome these limitations, and the use of lipidic encapsulation systems is a promising technique to achieve an efficient drug delivery, protecting molecules from external factors and improving their bioavailability.

Recurrent giant cell tumour of the maxillary sinus and pterygoid process treated with denosumab.

We report the case of a 74-year-old man with a giant cell tumour (GCT) of the right maxilla and pterygoid process. The patient presented to the maxillofacial and head and neck surgery clinic with an ulcerated lesion of the hard palate. Initial workup with CT revealed a mass within the right maxillary sinus and pterygoid process with associated bone expansion and erosion.

Atypical mandibular metastasis as the first presentation of a colorectal cancer.

We describe a case of a 70-year-old man presenting with a mandibular metastasis as the first sign of a mucinous adenocarcinoma of the rectum. After 6 months of a protracted toothache, the patient presented with a palpable mandibular mass and trismus, precluding adequate clinical evaluation. A CT scan was performed, and imaging findings suggested an aggressive primary jawbone tumour, most likely an osteosarcoma.

Ganglioneuroma of the retropharyngeal space in a patient with glottic cancer.

We describe the case of a 71-year-old man with a ganglioneuroma of the retropharyngeal space. The patient presented with a submucosal bulge of the left oropharyngeal wall during follow-up examination of a treated vocal cord carcinoma. CT and MRI revealed a non-specific, well-defined retropharyngeal soft tissue lesion.

Microbleeds and cavernomas after radiotherapy for paediatric primary brain tumours.

Background: With the expected growth and aging of the population of primary central nervous system tumours (PCNST) survivors, attention to the radiation-induced late brain injury is fundamental. Late focal hemosiderin deposition (FHD) lesions, namely microbleeds and cavernomas, are among the presumable late cerebrovascular complications associated with radiotherapy for PCNST.

Objective: To explore association between PCNST radiotherapy and the occurrence FHD lesions and to address the correlation between the topographic location of these microvascular lesions with the focal radiotherapy location.

Primary intraosseous squamous cell carcinoma of the mandible: a case with atypical imaging features.

Primary intraosseous squamous cell carcinoma is a rare malignant tumour that exclusively arises within the jaws. Its diagnosis requires an appropriate clinical, imaging and histological correlation. The exclusion of primary oral mucosa lesions and metastatic disease is mandatory.

Chondrosarcoma of the hyoid bone: an atypical site of a sarcoma of the head and the neck.

We describe a case of a 73-year-old man with a chondrosarcoma of the hyoid bone. The patient presented with a painless palpable lump in the upper anterior cervical region that had been growing for over 10 months. Fine-needle aspiration cytology suggested pleomorphic adenoma but further imaging investigation with CT revealed an exophytic tumour originating from the body of the hyoid bone with prominent chondroid-like calcifications typical of a chondrosarcoma.

Preconditioning with peristaltic external pneumatic compression does not acutely improve repeated Wingate performance nor does it alter blood lactate concentrations during passive recovery compared with sham.

Application of dynamic external pneumatic compression (EPC) during recovery from athletic activities has demonstrated favorable effects on flexibility, soreness, swelling, and blood lactate (BLa) concentrations. However, the effects of "preconditioning" with a peristaltic pulse EPC device on subsequent performance and BLa concentrations have not been characterized. Herein, we demonstrate that pretreatment for 30 min with EPC has no effect on subsequent supramaximal exercise performance or BLa concentrations during passive recovery.

Peripheral conduit and resistance artery function are improved following a single, 1-h bout of peristaltic pulse external pneumatic compression.

Introduction: External pneumatic compression (EPC) is being employed for a widening range of clinical and non-clinical populations. However, EPC devices vary markedly in treatment pressures, duty cycles and application sites, and the acute effects of whole limb, lower pressure EPC on peripheral vascular function have not been determined.

Purpose: The purpose of this study was to determine the acute effects of a single bout of peristaltic pulse EPC on peripheral conduit and resistance artery function.

Considerations for SphygmoCor radial artery pulse wave analysis: side selection and peripheral arterial blood pressure calibration.

Methods employed for pulse wave analysis (PWA) and peripheral blood pressure (PBP) calibration vary. The purpose of this study was to evaluate the agreement of SphygmoCor PWA parameters derived from radial artery tonometry when considering (1) timing (before vs. after tonometry) and side selection (ipsilateral vs.
