The study evaluated the function of median sensory nerve fibers, as well as determining the relationship between its function with the duration of Carpal
Tunnel Syndrome (CTS) and body mass index (BMI) among CTS patients in Physiotherapy Unit, Universiti Kebangsaan Malaysia Hospital (HUKM). Thirty
subjects (6 males and 24 females) with mean age 53.30 ± 9.20 years and duration of the CTS 51.17 ± 50.22 months participated in this study. The sensitivity of median sensory nerve was evaluated using Current Perception
Threshold (CPT) Test with stimulation frequencies of 5 Hz, 250 Hz and 2000 Hz; which demonstrated the function of C, Aδ and Aβ nerve fiber respectively.
Majority of the CTS patients had normal function in the 3 types of median sensory nerve fiber. Forty percents of the subjects had abnormality in the Aâ function, 7% had abnormality of the Aβ function and 27% demonstrated
abnormality in the C fiber function. Spearman Correlation Test showed no significant relationship between the function of median sensory nerve and the
duration of CTS and body mass index (BMI) (p > 0.05). In conclusion, although majority of the patients demonstrated normal median sensory nerve function,
abnormality of the Aβ, Aδ and C fibers sensitivity in some patients requires attention to prevent worsening of the nerve function thus avoiding related
complications. Physiotherapists in HUKM may intensify the use of nervestimulating modalities such as Transcutaneous Electrical Nerve Stimulation (TENS) to normalize the nerve functions of these patients.

At least three major antigenic dengue 2 virus proteins were recognized by pooled dengue fever patients' sera in infected Aedes albopictus (C6/36) mosquito cells. Dengue virus envelope (E), premembrane (PrM) and non-structural protein 1 (NS 1) dimer were detected beginning on day 3 postinfection in both the cell membrane and cytosolic fractions. Using the patients' sera, the presence of antigenic intermediate core protein (C)-PrM and NS1-non-structural protein 2a (NS2a) in the cytoplasmic fraction of dengue 2 virus infected cells was revealed. The presence of a approximately 92 and approximately 84 kDa NS 1 dimer in the membrane (NS 1m) and cytosolic (NS 1c) fractions of C6/36 cells, respectively, was also recognized. Using individual patient's serum, it was further confirmed that all patients' sera contained antibodies that specifically recognized E, NS 1 and PrM present in the dengue 2 virus-infected cell membrane fractions, suggesting that these glycosylated virus proteins were the main antigenic proteins recognized in vivo. Detection of dengue 2 virus C antibody in some patients further suggested that C could be antigenic if presented in vivo.
