CASE DESCRIPTION: A 25-years old Chinese female, with no history of systemic or ocular disease, presented to the eye clinic with one-month history of right eye (RE) blurring of vision with foreign body sensation. On examination, there were dense white crystalline needle-like projections over inferior paracentral corneal stroma with intact epithelium. There was also presence of lower eyelid epiblepharon with lashes rubbing against the diseased area. Corneal scraping cultures were suggestive of bacterial infection. Patient responded well with corneal epithelium debridement, intensive topical antibiotics and epiblepharon correction to prevent further microtrauma.
CONCLUSIONS: The only contributing factor for ICK in our patient was trichiasis from epiblepharon. Repetitive microtrauma caused by the eyelashes lead to direct penetration and inoculation of normal ocular flora into the corneal stroma. Clinicians need to be vigilant in ruling out other possible causes such as lid abnormalities when managing an ICK patient without apparent risk factors.
METHODS: This retrospective cohort study included 40 patients with chronic knee OA who received GNB, 20 of whom underwent treatment with the USG technique and the other 20 with the ALG technique. Pain, stiffness, and functional limitation scores were assessed using the Western Ontario and McMaster Universities Osteoarthritis Index Questionnaire (WOMAC) and Numeric Rating Scale (NRS-11) at baseline and post-treatment day one, three weeks, and six weeks.
RESULTS: Both groups reported a significant reduction in WOMAC and NRS-11 scores as per their feedback on day one, three weeks, and six weeks post-treatment. Greater reductions in WOMAC and NRS-11 scores were reported by patients who received GNB via USG than by ALG technique, the difference achieving statistical significance at six weeks after treatment (p =0.026).
CONCLUSIONS: GNB administration using USG and ALG techniques are both effective in significantly reducing pain, stiffness, and functional limitation in patients suffering from chronic knee OA. Among the two techniques, USG appears to be more effective. Nevertheless, GNB guided by ALG continues to be a viable treatment modality, especially in healthcare settings with limited to no USG facilities.
METHODS: The protocol was registered prospectively in PROSPERO (CRD42021244823). Guidelines published over the last decade providing insights into cancer pain management and incorporating safe opioid practice were evaluated. The review's primary outcome was to evaluate the quality of cancer pain guidelines. Appraisal of guidelines for research and evaluation II (AGREE II) instrument was used to assess a guideline's quality. The ADAPTE collaboration-guideline adaptation resource tool kit (ADAPTE) provided insights into its adaptation based on specific questions within the guideline.
RESULTS: Fourteen cancer pain guidelines met the eligibility criteria and were included for quality evaluation. Eight guidelines were evaluated with combined AGREE II and ADAPTE process, attaining >66.7% in the rigour of development domain score, summated scaled domain score, and specific ADAPTE tools to evaluate the quality of each guideline. The intra-class correlation coefficient was utilised for resolving inter-rater agreement. 'Safe opioid practice' within a guideline was assessed for quality content implementation.
CONCLUSION: Combined AGREE II and ADAPTE identified four cancer pain guidelines, namely Ministry of Health Malaysia, National Comprehensive Cancer Network, NCEC-National Clinical Guideline, and World Health Organization, which were of the highest quality and incorporated safe opioid practice effectively.
CASE PRESENTATION: A 37 year old Malaysian Chinese parturient was admitted at 25 weeks gestation following a scan which suggested intrauterine death and placenta accreta. She was diagnosed to have congenital complete heart block after her first delivery eight years previously but a pacemaker was never inserted. These medical conditions make her extremely likely to experience massive bleeding and haemodynamic instability. Among the measures taken to optimise her pre-operatively were the insertion of a temporary intravenous pacemaker and embolization of the uterine arteries to minimize peri-operative blood loss. She successfully underwent surgery under general anesthesia, which was relatively uneventful and was discharged well on the fourth post-operative day.
CONCLUSION: Congenital heart block in pregnancies in the presence of potential massive bleeding is best managed by a team, with meticulous pre-operative optimization. Suggested strategies would include insertion of a temporary pacemaker and embolization of the uterine arteries to reduce the risk of the patient getting into life threatening situations.
Methods: Bedside instruments that can be used includes a measuring tape, compass, goniometer, inclinometer and cervical range of motion (CROM) instrument.
Discussion: Cervical flexion-extension, lateral flexion and rotation will be assessed with bedside instruments. This would aid in increasing accuracy and precision of objective measurement while conducting clinical examination to determine the cervical range of motion.
METHODS: This retrospective study comprised 284 right eyes. Patients aged 18 years or older with myopia up to -12.00 D and/or astigmatism up to -6.00 DC and who underwent femtosecond LASIK were recruited. Patients were divided into three subgroups: low myopia (-0.50 to -3.00 D), moderate myopia (>-3.00 to ≤-6.00 D), and high myopia (>-6.00 D), according to their pre-LASIK spherical equivalent (SE). The variables included for analysis were PCC (central 0-3.0 mm, pericentral 3.0-6.0 mm, and peripheral region 6.0-9.0 mm), PCE, PCA, internal anterior chamber depth, intraocular pressure, and central cornea thickness at the pre- and post-LASIK stages.
RESULTS: The central PCC remained unchanged across all three myopia subgroups at 1 month when compared to the pre-LASIK stage and remained stable at 6 months. The pericentral regions became flatter across all myopia subgroups at 1 month postsurgery (P < 0.001) and remained unchanged at 6 months. This trend was not seen in the peripheral cornea regions, which remained unchanged at 1 and 6 months post-LASIK when compared to pre-LASIK mean readings. There were minimal changes in post-LASIK posterior cornea astigmatism throughout follow-up. There was no incidence of post-LASIK surgery ectasia in this study population.
CONCLUSION: Post-LASIK, the different cornea subregions behaved differently. Overall, the posterior cornea surface remained stable post-LASIK across all myopia subgroups throughout follow-up.
METHODOLOGY: This study was conducted using daily confirmed cases of COVID-19 collected from the official Ministry of Health, Malaysia (MOH) and John Hopkins University websites. An Autoregressive Integrated Moving Average (ARIMA) model was fitted to the training data of observed cases from 22 January to 31 March 2020, and subsequently validated using data on cases from 1 April to 17 April 2020. The ARIMA model satisfactorily forecasted the daily confirmed COVID-19 cases from 18 April 2020 to 1 May 2020 (the testing phase).
RESULTS: The ARIMA (0,1,0) model produced the best fit to the observed data with a Mean Absolute Percentage Error (MAPE) value of 16.01 and a Bayes Information Criteria (BIC) value of 4.170. The forecasted values showed a downward trend of COVID-19 cases until 1 May 2020. Observed cases during the forecast period were accurately predicted and were placed within the prediction intervals generated by the fitted model.
CONCLUSIONS: This study finds that ARIMA models with optimally selected covariates are useful tools for monitoring and predicting trends of COVID-19 cases in Malaysia.
