BACKGROUND Dacryocystorhinostomy (DCR) is commonly performed for epiphora, dacryocystitis and during tumor surgery. External (EXT-DCR) and endoscopic DCR (END-DCR) are both practiced. END-DCR was initially performed with laser (EL-DCR) but has shifted to careful bone removal with mechanical drills (EM-DCR). High level evidence from comparative cohorts was(More)
Head and neck cancer consists of a diverse group of cancers that ranges from cutaneous, lip, salivary glands, sinuses, oral cavity, pharynx and larynx. Each group dictates different management. In this review, the primary focus is on head and neck squamous cell carcinoma (HNSCC) arising from the mucosal lining of the oral cavity and pharynx, excluding(More)
The TGF-beta superfamily of proteins produces a wide range of frequently opposing effects in different cells and tissues in the body. However, its activation and mode of action are only partially understood because of its complexity in structure and functions and the variability in its downstream targets. Current work on these cytokines focuses on their(More)
Over 90% of all adults human cancers are of epithelial origin comprising mainly of skin and aero-digestive tract cancers. A significant proportion of our discipline's workload consists of management of these cancers. This review article is to provide clinicians with a summary of the current research findings in invasion and metastasis of epithelial cancers(More)
OBJECTIVES Gene expression profiling has provided many insights into tumor progression but translation to clinical practice has been limited. We have previously identified a list of potential markers by the differences of expression profiling of seven matched head and neck cancer (HNSCC) tumors with autologous normal oral mucosa (NOM). Alpha B-crystallin(More)
Of all human cancers, HNSCC is the most distressing affecting pain, disfigurement, speech and the basic survival functions of breathing and swallowing. Mortality rates have not significantly changed in the last 40 years despite advances in radiotherapy and surgical treatment. Molecular markers are currently being identified that can determine prognosis(More)
BACKGROUND Chronic rhinosinusitis (CRS) is a heterogeneous disease defined by epithelial inflammation. The link between measures of traditional disease severity and markers of epithelial inflammation is poorly understood as prior research has focused on presence of polyps or degree of eosinophilia. The expression of 3 epithelial derived cytokines implicated(More)
OBJECTIVE To compare patients treated for acute myocardial infarction (AMI) in a Veterans Health Administration (VHA) facility to similar patients treated under Medicare. DATA SOURCES Administrative data on 13,129 elderly male veterans hospitalized for AMI in a VHA facility between October 1, 1996, and September 30, 1999, and a matched set of male(More)
Head and neck cancer (HNSCC) is one of the most distressing human cancers, causing pain and affecting the basic survival functions of breathing and swallowing. Mortality rates have not changed despite recent advances in radiotherapy and surgical treatment. We have compared the expression of over 13,000 unique genes in 7 cases of matched HNSCC and normal(More)
PURPOSE OF REVIEW Recent literature in chronic rhinosinusitis with nasal polyps (CRSwNP) has focussed on inflammatory mechanisms underlying the disease. Endotyping the histopathological features of the disease, rather than simple clinical phenotypes, reflects a change in our understanding of the disease and approach to management. This is paralleled by(More)
