Combined Nasal Endoscopic and Subfrontal Craniotomy for Resection Tumors of Anterior Skull Base.

Objective: Sinonasal tumors invading anterior skull base is difficult to treat in Otorhinolaryngology and Neurosurgery. Treatment requires the collaboration of ear, nose and throat (ENT) and neurosurgeon to remove the tumor completely. This study was to evaluate the outcome of combined technique nasal endoscopic and subfrontal approach in case of sinonasal tumors involving anterior skull base.

Hypermethylation of the gene promoter as the tumor DNA marker for nasopharyngeal carcinoma.

Background: is a tumor suppressor gene. The methylation of has been reported to be associated with nasopharyngeal tumorigenesis. However, the heterogeneity was high among different studies.

Upregulation of miRNA-155 in Nasopharyngeal Carcinoma Patients.

Background: The upregulation of miRNA-155 (miR-155) has been associated with oncogenesis of many human tumors, including nasopharyngeal carcinoma (NPC). However, the profile of miR-155 in Vietnamese NPC patients has not been investigated. The current study aimed to evaluate the miR-155 expression and assess whether miR-155 is a potential biomarker for diagnosis of NPC in Vietnamese patients.

Molecular Screening of Nasopharyngeal Carcinoma: Detection of LMP-1, LMP-2 Gene Expression in Vietnamese Nasopharyngeal Swab Samples.

Objective: This study aimed to characterize the expression of LMP-1, LMP-2 in clinical swab samples in order to find out the potential molecular based biomarker for NPC diagnosis and screening, which could offer a chance in development of rapid method for NPC diagnosis in Vietnamese population. Materials and Methods: A total of 93 nasopharyngeal carcinoma swab samples and 100 healthy nasopharyngeal swab samples were collected to evaluate LMP-1, LMP-2 expression by Real-time reversed PCR. Results: we figured out the significant association between the expression of LMP-1 (counting for 48.

Vascular access for hemodialysis: Current practice in Vietnam.

A well-functioning vascular access is a mainstay to perform an efficient hemodialysis procedure, which directly affects the quality of life in hemodialysis patients. We use three main types of access: native arteriovenous fistula, arteriovenous graft, and central venous catheter. Arteriovenous fistula remains the first and best choice for chronic hemodialysis.

miR-141 is up-regulated in biopsies from Vietnamese patients with nasopharyngeal carcinoma.

Novel biomarkers for screening, diagnosis and monitoring the treatment of nasopharyngeal carcinoma (NPC), one of the most common cancers in Vietnam, are urgently required. Increasing evidence suggests that microRNA-141 (miR-141) is associated with NPC, owing to its ability to affect the expression of genes that modulate tumorigenesis. Unfortunately, research on miR-141 expression in Vietnamese patients is limited.

Molecular Screening for Epstein-Barr virus (EBV): Detection of Genomic EBNA-1, EBNA-2, LMP-1, LMP-2 Among Vietnamese Patients with Nasopharyngeal Brush Samples.

Epstein-Bar virus (EBV) is considered to be intimately associated with development of nasopharyngeal carcinoma (NPC), the most common and high incidence cancer of the head and neck in Asian countries, especially in Vietnam. In this study, we validated associations between highly conserved segments of the EBV genome, including EBNA-1, EBNA-2, LMP-1, LMP-2 and nasopharyngeal cancer, with the aim of applications with non-invasive brush samples for early diagnosis and as a prognostic biomarker. The polymerase chain reaction (PCR) was performed to assess the presence of EBNA-1, EBNA-2, LMP-1, LMP-2 in nasopharyngeal brush samples from Vietnamese NPC patients and non-cancer controls.

Prevalence of zoonotic metacercariae in two species of grouper, Epinephelus coioides and Epinephelus bleekeri, and flathead mullet, Mugil cephalus, in Vietnam.

Fishborne zoonotic metacercariae have not been reported from brackish water and marine fish from Vietnam waters although these parasites are common in the country's freshwater fish. Both wild-caught and cultured grouper (Epinephelus coioides and Epinephelus bleekeri), and mullet (Mugil cephalus) from brackish and marine waters located in Khanh Hoa province in central coastal Vietnam were examined, and found positive for zoonotic trematode metacercariae. From grouper, Heterophyopsis continua and Procerovum varium were recovered.
