OBJECTIVES: To evaluate and compare the depth and distances from various points of the orbital rim to the fissures and foramina of the orbital apex between genders in the local population.
METHODOLOGY: Linear measurements were conducted on 60 orbits from 30 patients who had undergone head computed tomography scan. These measurements were done utilizing the multiplanar reconstruction modes on computed tomography images with minimum slice thickness of 1 mm.
RESULTS: Males have statistically significant larger orbits than females with higher mean measurements in all parameters, except for the distance from posterior ethmoidal foramen to the optic canal which was the same. However, there were no significant differences in all parameters between the right and left orbits.
CONCLUSION: This study provides the absolute limit of safe internal orbital dissection in respect to the local population. Despite males having larger orbits than females, it is clinically negligible.
CASE PRESENTATION: Herein, we report on a middleaged male who presented with left-sided spontaneous epistaxis and aural fullness with no neck node which turned out to be basaloid cell carcinoma of nasopharynx.
DISCUSSION AND CONCLUSION: We highlight high clinical suspicion of rare variant of nasopharyngeal carcinoma although no palpable node was evident upon presentation.
Discussion: The scenario is made worst if the aspiration causes acute hypoxemic respiratory failure immediately post intubation. However, in the event of desaturation, the quick decision to proceed with bronchoscopy is a challenging task to the anesthesiologist without knowing the causes.
Case presentation: We present a case of a 12-year-old boy who had a difficult-to-ventilate scenario post transferring and immediately connected to ventilator in operation theatre (OT) from portable ventilator from the emergency department. She was successfully managed by bronchoscopy.
Conclusion: Special attention should be given to the difficult-to-ventilate scenario post intubation of traumatic brain injury patient prior to operation. Prompt diagnosis and bronchoscope-assisted removal of foreign body was found to be a successful to reduce morbidity and mortality.
METHODOLOGY: A quasi-experimental study was conducted at three time-points (pre-intervention, post-intervention and one-month after working as a HO) on the level of confidence and readiness of medical graduates. The intervention was the Medicorp module, which included information and training needed for the HO such as common clinical cases in the wards, case referrals, experience sharing and hands on clinical training. We recruited eligible participants undergoing the course between April-November 2018. The adapted IMU Student Competency Survey was used to measure the confidence and readiness levels, which were scored from a Likert scale of 1-5. The higher score indicated higher levels of confidence or readiness.
RESULTS: A total of 239 participants were recruited at baseline (90% response rate). They were mostly female (77.8%), Malays (79.1%), single (90.0%), graduated overseas (73.6%), in 2018 (65.3%). The mean (SE) confidence scores significantly increased from 2.18 (1.00) pre-course to 3.50 (0.75) immediately after course and 3.79 (0.92) after one-month of work (p <0.001, η2 = 0.710). The mean (SE) readiness scores at pre-course, immediately and one-month post work were 2.36 (1.03), 3.46(0.78) and 3.70(0.90), respectively (p< 0.001, η2 = 0.612).
CONCLUSION: The HO Preparatory Course module was effective in increasing levels of confidence and readiness for medical graduates, most of whom are overseas graduates; namely Egypt, Russia and Indonesia.
MATERIALS AND METHODS: The clinic-based prospective evaluation included all suspected measles cases captured by routine measles surveillance at 34 purposely selected clinics in 15 health districts in Malaysia between September 2019 and June 2020, following day-long regional trainings on RDT use. Following informed consent, four specimens were collected from each suspected case, including those routinely collected for standard surveillance [serum for EIA and throat swabs for quantitative reverse transcriptase polymerase chain reaction (RT-qPCR)] together with capillary blood and oral fluid tested with RDTs during the study. RDT impact was evaluated by comparing the rapidity of measles public health response between the pre-RDT implementation (December 2018 to August 2019) and RDT implementation periods (September 2019 to June 2020). To assess knowledge, attitudes, and practices of RDT use, staff involved in the public health management of measles at the selected sites were surveyed.
RESULTS: Among the 436 suspect cases, agreement of direct visual readings of measles RDT devices between two health clinic staff was 99% for capillary blood (k = 0.94) and 97% for oral fluid (k = 0.90) specimens. Of the total, 45 (10%) were positive by measles IgM EIA (n = 44, including five also positive by RT-qPCR) or RT-qPCR only (n = 1), and 38 were positive by RDT (using either capillary blood or oral fluid). Using measles IgM EIA or RT-qPCR as reference, RDT sensitivity using capillary blood was 43% (95% CI: 30%-58%) and specificity was 98% (95% CI: 96%-99%); using oral fluid, sensitivity (26%, 95% CI: 15%-40%) and specificity (97%, 95% CI: 94%-98%) were lower. Nine months after training, RDT knowledge was high among staff involved with the public health management of measles (average quiz score of 80%) and was highest among those who received formal training (88%), followed by those trained during supervisory visits (83%). During the RDT implementation period, the number of days from case confirmation until initiation of public response decreased by about 5 days.
CONCLUSION: The measles IgM RDT shows >95% inter-reader agreement, high retention of RDT knowledge, and a more rapid public health response. However, despite ≥95% RDT specificity using capillary blood or oral fluid, RDT sensitivity was <45%. Higher-powered studies using highly specific IgM assays and systematic RT-qPCR for case confirmation are needed to establish the role of RDT in measles elimination settings.
