BACKGROUND: Timely initiation of therapy for neonatal hyperbilirubinemia is routinely made based on total serum bilirubin levels. However, serial samplings by invasive needle pricks are needed for laboratory analyses. Studies comparing the correlation between serum bilirubin and transcutaneous bilirubin have yielded diverse results. A meta- analysis was done to find out the relationship between transcutaneous bilirubin measurements and serum bilirubin values. OBJECTIVE: This study aims to analyze scientific articles regarding the accuracy of transcutaneous bilirubin measurements among healthy neonates as an alternative screening for hyperbilirubinemia. STUDY DESIGN: Diagnostic Accuracy meta- analysis. METHODS: Studies on the accuracy of transcutaneous bilirubin measurements were identified through intensive literature search. Local studies were confirmed thru personal communication. RESULTS: Three hundred eighteen studies were identified through literature search. Ten studies met the eligibility criteria. Eight of the ten studies reported results as correlation coefficients. The pooled estimates of correlation coefficients is high at r = 0.85 (95% CI = 0.84 to 0.857). Five studies reported results with data for diagnostic accuracy. The pooled analysis for sensitivity and specificity are high at 0.84 (95% CI 0.8-0.88) and 0.79 (95% CI 0.77-0.81) respectively. The pooled likelihood ratio has a significant difference with a pooled positive LR of 4.19 (95% CI 2.98-5.9, P<0.01) while the negative likelihood ratio is 0.23 (95% CI: 0.17 to 0.29). The AUC for transcutaneous bilirubinometry is 0.89. CONCLUSIONS Transcutaneous bilirubin measurement can be an alternative in monitoring the risk of healthy neonates for hyperbilirubinemia based on the pooled analysis of correlation coefficient and diagnostic accuracy.

Myxoid liposarcoma is the major subtype of liposarcoma and commonly presents in the extremities, particularly in the thigh. We introduce an unusual case of a myxoid liposarcoma presenting as a large perineal swelling occupying the para-rectal and para-anal spaces in a 49-yearold male patient. The diagnosis, management, and prognosis of myxoid liposarcoma are discussed. A literature review is performed for myxoid liposarcoma.

In Malaysia, it is a common belief among health care workers that females and Indians have lower pain threshold. This experience, although based on anecdotal experience in the healthcare setting, does not allow differentiation between pain tolerance, and pain expression. To determine whether there is a difference in the tolerance to pain between the three main ethnic groups, namely the Malays, Chinese and Indians as well as between males and females. This was a prospective study, using a laboratory pain model (ischaemic pain tolerance) to determine the pain tolerance of 152 IMU medical students. The mean age of the students was 21.8 years (range 18-29 years). All of them were unmarried. The median of ischaemic pain tolerance for Malays, Chinese and Indians were 639s, 695s and 613s respectively (p = 0.779). However, statistically significant difference in ischaemic pain tolerance for males and females Indian students were observed. Possible ethnic difference in pain tolerance in casual observation is not verified by this laboratory pain model. Difference in pain tolerance between genders is shown only for Indians.
