Carcinoma of unknown primary is uncommon, estimated to represent only 3% to 5% of all head and neck cancers. Squamous cell carcinoma accounts for 70% to 90% of these lesions, most commonly from sites in the upper aerodigestive tract, including tonsils, base of tongue, nasopharynx, and piriform sinus. Magnetic resonance, computed tomography (CT), and positron emission tomography all play a role in the assessment of patients with an unknown primary. The location of a metastatic lymph node may give an indication of the primary tumor site, and knowledge of lymph node drainage patterns is important for anyone evaluating these patients. Magnetic resonance and CT are both used for evaluation for extracapsular nodal disease, perineural tumor spread, osseous skull base or perivertebral space involvement, and vascular invasion, findings that seriously impact treatment and prognosis. Positron emission tomography/CT also plays a significant role in detecting primary tumor sites and identifying distant metastatic disease.

Background: With the growing number of high-risk pregnant women, echocardiography frequently reveals pericardial effusion (PE). However, the clinical implications of PE are unknown.
Method: We analyzed a cohort of 406 high-risk pregnant women who underwent echocardiography in the third trimester between November 2019 and December 2022.

Introduction: Preclinical studies have shown that oxygen therapy can improve ischaemic brain tissue oxygen tension, reduce reperfusion injury after revascularisation, promote neuroregeneration and inhibit inflammatory responses potentially exerting a beneficial effect after endovascular treatment (EVT) in patients with acute ischaemic stroke (AIS). However, the optimal fraction of inspired oxygen (FiO) during EVT under general anaesthesia is currently unknown. Therefore, we are conducting a randomised controlled trial (RCT) to evaluate the impact of high-concentration oxygen vs low-concentration normobaric oxygen on early neurological function after EVT.

Carcinoma of unknown primary (CUP) comprises 2-5% of cancer diagnoses worldwide, with a prevalence that has modestly declined with increased availability of advanced diagnostic tools such as next-generation sequencing (NGS). This case presentation illustrates the possibilities and gaps that remain with improving diagnostic capabilities in identifying and effectively treating CUP. This is the case of a rapidly enlarging right axillary mass without a primary tumour site and histological evaluation demonstrating a poorly differentiated neoplasm.

Psoriasis is a noncontagious, autoimmune chronic inflammatory disease with an unknown root cause. It is classified as a multifactorial and chronic skin disorder that also affects the immune system and is genetic. Environmental factors such as stress, infections, and injuries all play an important role in the disease's development.
