RESUMEN
The aim of this study was to investigate current epidemiology of several types of oral clefts among the patients receiving treatment at two tertiary care hospitals, namely University Malaya Medical Centre [UMMC] Kuala Lumpur, and Hospital Kota Bharu / Hospital Raja Perumpuan Zainab II [HKB/ HRPZII] Kelantan. This study evaluated the records of 526 cleft lip and palate [CLP] patients with or without additional malformations, who came for treatment during 2003 to 2007. Of the total 526 patients registered in the study hospital records during the study period, 338 were from HKB/ HRPZ II and 188 from UMMC. Majority 86.7% of these patients were in the age group - =18years. The results of this study show that 57% females and 43% males were affected by oral cleft. Out of the total patients, 77.8% were CLP, 13.5% were cleft palate [CP], and 8.7% were cleft lip [CL] patients. Moreover 57.2% patients were with unilateral cleft, 32.7% were left sided and 24.5% were right sided. Total 42.8% patients were with bilateral oral cleft. To best of our knowledge this is the first reported multi-center study on CLP in Malaysia with regard to the proportion of different types of oral clefts

Cervical cancer is the third most common cancer among women in Malaysia. The objective of this study was to estimate the effect of explanatory variables on survival time of cervical cancer patients receiving treatment at a hospital in Malaysia. In this retrospective record review study, cervical cancer data obtained from Hospital Universiti Sains Malaysia [HUSM] was analyzed. The data comprises of 120 patients who had been diagnosed as cervical cancer between 1[st] July 1995 and 30[th] June 2007, and obtained treatment from the hospital. The outcome variable was survival time [in months] from cervical cancer diagnosis to death. A stratified Weibull model was applied to study the effect of explanatory variables on survival time when there was time-dependent covariate in the model. Stage of disease and metastases were important prognostic variables. However, metastasis had been stratified because this variable did not satisfy the proportional hazard assumption. In without metastasis stratum, patients who were diagnosed at stage III and IV are at 2.30 times the risk of death as those in stage I and II. Meanwhile, in with metastasis stratum, patients in stage III and IV group had 3.53 times the hazard faced by patients in stage I and II. The prognosis of cervical cancer patients was dependent upon the stage at diagnosis, after the stratification of the metastasis variable. A poorer prognosis on survival was observed for patients in stage III and IV than those in stage I and II
