T he limping child may present a significant challenge to the physician. In order to arrive at the correct diagnosis, the clinician must approach each patient in an organized fashion. In general, disorders that cause limping vary from age group to age group. This article will examine three different age groups relative to the disorders leading to gait disturbances. The three groups are toddlers...

Background Nasopharyngeal carcinoma, common in Southeast Asia, is mainly a non-keratinizing, squamous cell carcinoma (NK-NPC) and clinically heterogeneous. Methods Herein, we analyzed three human gene expression microarray datasets characterizing 81 NK-NPC tumors and 21 normal nasopharyngeal (NP) tissues to identify molecular subtypes of NK-NPC. In one of the datasets, QRT-PCR measurement of ex...

MiR-125b is aberrantly expressed and has a role in the various types of tumors. However, the role and mechanism of miR-125b in nasopharyngeal carcinoma (NPC) are unclear. In this study, we investigated the role and mechanism of miR-125b in NPC. We observed that miR-125b was significantly upregulated in the NPC tissues relative to normal nasopharyngeal mucosa (NNM), and its increment was correla...

To identify metastasis-related proteins in nasopharyngeal carcinoma (NPC), iTRAQ-tagging combined with 2D LC-MS/MS analysis was performed to identify the differentially expressed proteins (DEPs) in high metastatic NPC 5-8F cells and non-metastatic NPC 6-10B cells, and qRT-PCR and Western blotting were used to confirm DEPs. As a result, 101 DEPs were identified by proteomics, and 12 DEPs were se...

OBJECTIVES Alberta maintains a universal screening program for congenital hypothyroidism, a condition which, when treated promptly prevents neurological impairment. Because the program relies on multiple stakeholders working in different areas, it is not known how effective the overall process is in achieving timely treatment initiation. Our objective was to analyze and describe the informatics...

OBJECTIVE Epidermoid growth factor receptor (EGFR, HER1) is overexpressed in a majority of head-and-neck cancers, including nasopharyngeal carcinoma (NPC). Although EGFR inhibitors appear to be effective for some head-and-neck cancers, their efficacy in NPC remains unclear. METHODS The effect of EGFR-specific tyrosine kinase inhibitors, including PD153035 and ZD1839, were studied in NPC-TW01,...

Radioresistance continues to be a major problem in the treatment of nasopharyngeal carcinoma (NPC). This study aimed to identify novel proteins associated with NPC radio-resistance. We used a mass spectrometry driven-proteomic strategy to identify novel proteins associated with NPC radio-resistance, and differential proteins were subsequently proc...

IT is a great pleasure to be able unreservedly to recommend any book-and this is one of those occasions. To the physician or rheumatologist this small volume outlines precisely what can be expected from the various modes of imaging on patients suffering from bone or joint disease. To the radiologist it presents clearly the requirements of the clinician. The chapters are well chosen. The illustr...

We explore several machine learning techniques to model clinical decision making of 6 dermatologists in the clinical task of melanoma diagnosis of 177 pigmented skin lesions (76 malignant, 101 benign). In particular we apply Support Vector Machine (SVM) classifiers to model clinician judgments, Markov Blanket and SVM feature selection to eliminate clinical features that are effectively ignored ...
