    The fairness of raters in music performance assessment has become an important concern in the field of music. The assessment of students' music performance depends in a fundamental way on rater judgements. The quality of rater judgements is crucial to provide fair, meaningful and informative assessments of music performance. There are many external factors that can influence the quality of rater judgements. Previous research has used different measurement models to examine the quality of rater judgements (e.g., generalizability theory). There are limitations with the previous analysis methods that are based on classical test theory and its extensions. In this study, we use modern measurement theory (Rasch measurement theory) to examine the quality of rater judgements. The many-facets Rasch rating scale model is employed to investigate the extent of rater-invariant measurement in the context of music performance assessments related to university degrees in Malaysia (159 students rated by 24 raters). We examine the rating scale structure, the severity levels of the raters, and the judged difficulty of the items. We also examine the interaction effects across musical instrument subgroups (keyboard, strings, woodwinds, brass, percussions and vocal). The results suggest that there were differences in severity levels among the raters. The results of this study also suggest that raters had different severity levels when rating different musical instrument subgroups. The implications for research, theory and practice in the assessment of music performance are included in this paper.

    Bronchopulmonary lophomoniasis is rare but immunocompromised individual is susceptible to this infection. We reported a case of bronchopulmonary lophomoniasis in a Malaysian female with systemic lupus erythromatosus. She presented with productive cough, shortness of breath and high-grade fever for 2 weeks. Physical examination revealed bronchial sound and crackles over the left lung with, reduced expansion and dull percussion in lower left lobe. Chest radiography showed consolidation of the left lung. Routine laboratory tests revealed general low cell count. Blood and sputum culture were negative. Bronchoalveolar lavage stain and culture for bacterial and fungal were negative. Bronchoalveolar lavage for Lophomonas blattarum was positive. Patient was treated with antiprotozoal drug, metronidazole. All her clinical problems resolved and she was discharged 14 days after admission.

    Groundwater in fractured metasedimentary rock in Malaysia is a potential source of water for drinking and industrial uses. Industries including agricultural processing, mineral water bottling, manufacturing and golf courses pumped the water from the underlying fractured rocks. Fifty eight tubewells belong to private companies operating in various places in West Coast of Peninsular Malaysia were evaluated for their yield and quality of water. Rotary percussion methods were used for the drilling to a maximum depth of 200 m. The productivity of the wells and the characteristics of the aquifer were evaluated by pumping test using both the constant discharge rate and steps drawdown methods. The average yield of the wells at allowable drawdown of 40 m was found to be 416 m3 per day. Results from water quality analysis indicated that the water was fresh with an average total dissolved solids (TDS) concentration of 101 to 150 mg/L. The hardness of the water varies from as low as 13 mg/L to a maximum of 353 mg/L. On the average, the water was moderately hard with the average hardness value of 80 mg/L. The water facies of the groundwater was found to be of calcium-sodium-bicarbonate water.

    INTRODUCTION: Chest physiotherapy (CPT) may benefit children aged < 5 years who suffer from lower respiratory tract infection (LRTI). However, its effects are technique-dependent. This study aimed to determine whether mechanical CPT using the LEGA-Kid® mechanical percussion device is superior to manual CPT in children with LRTI.

    METHODS: Children aged 5 months to 5 years who were admitted and referred for CPT from January to April 2017 were randomised to either manual CPT or mechanical CPT with LEGA-Kid®. Outcomes measured at pre-intervention and 2 hours post-intervention were respiratory rate (RR), oxygen saturation and modified Respiratory Distress Assessment Instrument (mRDAI) score.

    RESULTS: All 30 enrolled patients had significant reduction in post-intervention RR and mRDAI scores. There was an 8% reduction in RR for the manual CPT group (p = 0.002) and a 16.5% reduction in the mechanical CPT group (p = 0.0001), with a significantly greater reduction in the latter (p = 0.024). mRDAI scores decreased by 2.96 in the manual group (p = 0.0001) and 3.62 in the mechanical group (p = 0.002), with no significant difference between the groups. There was no significant improvement in oxygen saturation, and no adverse events were observed after CPT.

    CONCLUSION: Children receiving either manual or mechanical CPT showed improvements in respiratory distress symptoms with no adverse effects. A combined strategy of nebulised hypertonic saline followed by CPT for LRTI removes airway secretions and results in improvements of moderately severe respiratory distress. The LEGA-Kid mechanical CPT method was superior in reducing RR.

    Objective: The purpose of this article was to report the finding of the disappearance of intracanal medication as a supporting evidence of vertical root fracture (VRF) through non-surgical intervention.

    Methods: A retrospective review of the dental records of patients seen by an endodontist in a private endodontic office from September 2013 to September 2016 was conducted by the same endodontist. Cases that met the inclusion and exclusion criteria were assigned as the subjects of this study, and data were extracted from their clinical and radiographic records. Patient's demographic features, pre-operative signs and symptoms, details of rendered clinical procedures, follow-up visits, clinical and radiographic findings were recorded. Seventeen teeth for which non-surgical exploratory re-treatment was initiated were included in this study. Calcium hydroxide-based intracanal medication was placed for 2-4 weeks. Obturation of the root canals was performed if the tooth showed improvement of clinical signs and symptoms. If not, a cone-beam computed tomography (CBCT) scan was proposed to the patient to rule out VRF.

    Results: After the non-surgical re-treatment was initiated, 13 teeth showed improvement of clinical symptoms and the re-treatment was therefore completed. The remaining 4 teeth presented with unresolved clinical presentations (deep pocket, presence of sinus tract and/or tender to percussion and palpation). Four teeth showed partial disappearance of intracanal medication where VRF was confirmed using CBCT in 3 teeth and with a conventional periapical (PA) radiograph in 1 tooth.

    Conclusion: The disappearance of intracanal medication during non-surgical intervention was often associated with VRF. Thus, this feature may serve as an aid in diagnosing VRF.

    Although the use of appropriate antibiotics has significantly improved the outcome of pneumonia, severe complications are still encountered. We report here of a case with invasive pneumococcal pneumonia with massive empyema. A 2-year-4-month old girl presented with fever for 8 days and intermittent cough for 2 weeks. On examination, reduced air entry with dullness on percussion was noted on the left lung. Chest ultrasound revealed moderate to gross pleural effusion with septations, for which left thoraco-centesis with insertion of pigtail tube was performed. Streptococcus pneumoniae was detected via polymerase chain reaction (PCR) test in the pleural fluid. Intravenous (IV) benzylpenicillin and ceftriaxone were given together with one course (5 days) of intrapleural urokinase to breakdown the septations. Timely and appropriate management of pneumonia including the use of thrombolytic agent is vital to ensure optimal outcome and reduce the need of invasive procedures in cases with massive empyema. Public awareness of pneumococcal vaccination is also essential as a part of preventive measures.
