Crinum asiaticum and Hymenocallis littoralis, commonly known as spider lilies are bulbous perennial and herbaceous plants that widely planted in Malaysia as ornamental. During 2015–2016, symptom of leaf blight was noticed on the hosts from several locations in Penang. The symptom appeared as irregular brown to reddish lesions surrounded by yellow halos. As the disease progressed, the infected leaves became blighted, dried, and fell off with the presence of black microsclerotia and pycnidia on the lesions parts. The present study was conducted to investigate the causal pathogen of leaf blight on C. asiaticum and H. littoralis. Based on morphological characteristics and DNA sequences of internal transcribed spacer (ITS) region and translation elongation factor 1-alpha (TEF1-α) gene, the causal pathogen was identified as Macrophomina phaseolina. Phylogenetic analysis of combined dataset of ITS and TEF1-α grouped the isolates studied with other isolates of M. phaseolina from GenBank. The grouping of the isolates was supported by 96% bootstrap value. Pathogenicity test proved the role of the fungus in causing leaf blight on both hosts.

INTRODUCTION: Arthroscopic Bankart repair is a widely accepted procedure to treat recurrent shoulder dislocation. This study aims to describe our experience with arthroscopic Bankart repair and its functional outcome. METHODS: 107 patients who underwent arthroscopic Bankart repair from 2008 to 2013 were followed up for a minimum of three years and reviewed by an independent observer. 80 consented to being interviewed using the Oxford Shoulder Instability Score (OSIS) and Simple Shoulder Test. RESULTS: 82 shoulders (two bilateral) were studied. Mean age at first dislocation was 19.4 ± 3.4 (12.0-31.0) years. Mean follow-up was 4.4 ± 1.3 (3.0-9.0) years and 2.5 ± 3.0 (0.1-15.4) years elapsed from first dislocation to surgery. 41 (50.0%) patients played overhead or contact sports and 44 (53.7%) played competitive sports before injury; 8 (9.8%) patients reported recurrence of dislocation, which was significantly associated with playing competitive sports before injury (p <0.039), 5 (6.1%) underwent revision surgery and 22 (26.8%) reported residual instability after surgery. 49 (59.8%) patients returned to playing sports, 75 (91.5%) were satisfied with their surgery and 79 (96.3%) were willing to undergo the surgery again. 74 (90.2%) patients had two-year good/excellent OSIS, which was significantly associated with playing competitive sports before injury (p = 0.039), self-reported stability after surgery (p = 0.017), satisfaction with surgery (p = 0.018) and willingness to undergo surgery again (p = 0.024). CONCLUSION Arthroscopic Bankart repair yields good functional outcomes and is associated with high patient satisfaction, although not all patients return to sports.

Introduction: Multitude studies have shown perception is an integral factor associated with smoking, However, no such tool was available in Malay language. In this study, we established a Bahasa Malaysia version of PTSQ (BM-PTSQ) and tested the validity and reliability among secondary school adolescents. Methods: The English version of PTSQ originally consists of 12 items. It was translated into Bahasa Malaysia and back-translated again into English to check for consistency. After face validity (face-to-face query) was determined among 20 secondary school adolescents, only 10 items were included in the survey. Construct validity was established from 407 school adolescents through random selection in the same locality. More than 60% of the respondents were female, a majority (67.3%) were schooling in rural areas. Then, the reliability of the questionnaire was determined with Cronbach's alpha. Results: EFA has grouped PTSQ into two components, they are associated with either knowledge or attitude towards smoking. The variance and Cronbach's alpha for the first and second component were 38.24% and 0.861 (7 items) and 21.62% and 0.661 (3 items) respectively. Conclusion The PTSQ showed good validity and reliability for measurement of perception in smoking among school adolescents in Malaysia, thus this is a viable measurement tool. More importantly this study shows an urgent need to improve the smoking education among adolescents in Malaysia.
