Leucine-rich-α-2-glycoprotein 1 (LRG1) is considered as a potential biomarker as it is aberrantly expressed in various malignancies. However, there is limited information regarding its role in head and neck squamous cell carcinoma (HNSCC). In the present study, we aimed to explore the expression pattern of LRG1 in HNSCC and its clinicopathological significance. We first analyzed LRG1 gene expression in HNSCC by investigating data obtained from the Gene Expression Omnibus (GEO) database. The results showed that LRG1 was downregulated in HNSCC tissues and its expression level was negatively related to tumor T and N stages and degree of malignancy...

Multidrug resistance (MDR) is a significant barrier to the effective treatment of bladder cancer. In order to improve the management of bladder cancer, it is crucial to identify strategies that may reverse MDR. The effects of three herbal medicines, ginsenoside Rh2, (‑)‑epigallocatechin gallate (EGCG) and resveratrol (RES) on bladder cancer were determined. The effect of these three herbal medicines against the drug resistance in adriamycin (ADM)‑resistant pumc‑91 cells (pumc‑91/ADM) was assessed using the Cell Counting Kit‑8 cell proliferation assay system...

A 73-year-old man was referred for F-FDG PET/CT study for staging of biopsy-proven pancreatic adenocarcinoma. The scan demonstrated focal intense FDG uptake in the pancreatic head, localizing the primary tumor. Additional moderate diffuse uptake was seen throughout the pancreas, suggestive of acute pancreatitis. Concurrent diagnostic CT showed diffuse pancreatic hypoenhancement consistent with edema. Serum lipase level was elevated, confirming a diagnosis of acute pancreatitis.

: We present the case of a 59-year-old man with a growing mass in his left axillary area. A biopsy and immunostainings demonstrated neuroendocrine carcinoma, which is Merkel cell carcinoma (MCC). The disease is characterised by neurosecretory granules in tumor cells. MCC is a rare entity. The disease is predominantly seen in the inguinal region or the axilla and typically found incidentally. It presents clinically as multiple lymph nodes enlargement. Yet controversy exists regarding treatment modality of MCC...

We report a fatal case of disseminated Emmonsia sp. infection in a 55-year-old man who received an orthotopic liver transplant. The patient had pneumonia and fungemia, and multisystem organ failure developed. As human habitats and the number of immunocompromised patients increase, physicians must be aware of this emerging fungal infection.

Nasopharyngeal carcinoma (NPC) is an aggressive head and neck cancer characterized by Epstein-Barr virus (EBV) infection and dense lymphocyte infiltration. The scarcity of NPC genomic data hinders the understanding of NPC biology, disease progression and rational therapy design. Here we performed whole-exome sequencing (WES) on 111 micro-dissected EBV-positive NPCs, with 15 cases subjected to further whole-genome sequencing (WGS), to determine its mutational landscape. We identified enrichment for genomic aberrations of multiple negative regulators of the NF-κB pathway, including CYLD, TRAF3, NFKBIA and NLRC5, in a total of 41% of cases...

Thromboembolic disease is an important and frequent complication in patients with the nephrotic syndrome (NS), and the consequences are often severe. Usually, the venous system is affected. Arterial thrombosis has rarely been reported and occurs mainly in children. We report the case of a 27-year-old man with a history of NS due to focal and segmental glomerulosclerosis resistant to steroids and cyclosporine, admitted for bilateral pain in the calves. Aortogram revealed a suspended thrombus in the abdominal aorta just below the origin of the renal arteries with embolism into the left tibioperoneal trunk and the right anterior tibial artery...

The incompatibility causing fetal and neonatal alloimmune thrombocytopenia (FNAIT) results from a fetus inheriting a paternal human platelet antigen (HPA), which is different from the maternal HPA. We present a unique case of FNAIT in a pregnancy involving an oocyte recipient mother with Turner syndrome. This is the first report of FNAIT in which the suggested mechanism involves antibodies produced by a gestational mother against the incompatible HPA of the oocyte donor.

Salmeterol is a man-made beta-2-adrenergic receptor agonist used to relieve bronchospasm associated with inflammatory airway disease in horses. Whilst judicious use is appropriate in horses in training, they cannot race with clinically effective concentrations of medications under the British Horseracing Authority's Rules of Racing. Salmeterol must therefore be withdrawn prior to race day and pharmacokinetic (PK) studies used to establish formal detection time advice. Salmeterol xinafoate (Serevent Evohaler(®) ) was administered (0...

Quadricuspid aortic valve is an extremely rare congenital heart anomaly that often causes valve incompetence, requiring surgical intervention. Care must be taken to avoid surgical complications in patients with quadricuspid aortic valve; thus, preoperative diagnosis is important. A 76-year-old man presented with exertional dyspnea due to aortic regurgitation. Transthoracic and transesophageal echocardiography revealed severe aortic regurgitation caused by quadricuspid aortic valve. To avoid interference with the cardiac conduction system, we performed aortic valve replacement using an ingenious technique, in which pledgeted sutures on the accessory leaflet were placed from outside the sinus of Valsalva to above the aortic annulus...
