Introduction: The morphology of the condyles changes naturally with age, gender, face type, occlusal force, functional load, malocclusion type, and the right and left sides. Although condylar shape and size differ throughout populations, there have been few investigations on condylar morphology, particularly in the Malaysian population. Methods: This retrospective, observational, cross-sectional survey was conducted at the Oral and Maxillofacial Surgery Clinic of Sarawak General Hospital from September 2021 to March 2022, involving radiographic assessment of condylar morphology from 893 panoramic radiographs. Age, gender, ethnicity and dentition status using Eichner index were extracted from the data. Descriptive statistics were used. Pearson’s chi-square test was used to determine the association between the independent variables (age, gender, ethnicity and dentition status) and the shape of the mandibular condyle. A p-value of < 0.05 was considered statistically significant. Results: Only 450 panoramic radiographs were included in this study. The condyles were outlined and grouped into four categories, namely pointed (40.2%), round (32.8), angled (18.8), and flat (8.2%). Condylar morphology was found to be significantly associated with gender (p<0.005) and insignificant with other independent variables. Conclusion: The findings suggest that the most prevalent condylar morphology among the Sarawak population is the pointed shape, in contrast with other previous studies that reported the round shape condylar morphology as the majority shape.

Accessory cusps are occasional variations in tooth morphology that can be detected clinically. Third molars have a wide range of eruption patterns and shapes but are commonly impacted. Unlike root morphology, variations in the crown morphology of the third molar have rarely been reported. Variations in crown morphology are important because they can affect clinical outcomes. Here, we present a rare case of fully erupted mandibular third molar (MTM) with multiple accessory cusps. This case report describes a case of a 31-year-old female Kenyah with a unique crown morphology of her fully erupted, vital, and functional mandibular third molar (MTM) which has multiple accessory cusps seen on the buccal surface, giving the appearance of a double tooth. Her MTM presented with an incipient caries lesion, which was managed conservatively. Documenting variations in tooth morphology is crucial for individual identification. While most people opt to have their MTMs extracted, early management of well-erupted and functional teeth should be undertaken to prevent disease progression.

Stroke is a major cause of death and long-term disability worldwide. Diabetes is associated with an increased risk of cardiovascular complications, including stroke. People with diabetes have a 1.5–2 times higher risk of stroke compared with people without diabetes, with risk increasing with diabetes duration. These risks may also differ according to sex, with a greater risk observed among women versus men. Several mechanisms associated with diabetes lead to stroke, including large artery atherosclerosis, cerebral small vessel disease, and cardiac embolism. Hyperglycemia confers increased risk for worse outcomes in people presenting with acute ischemic stroke, compared with people with normal glycemia. Moreover, people with diabetes may have poorer post-stroke outcomes and higher risk of stroke recurrence than those without diabetes. Appropriate management of diabetes and other vascular risk factors may improve stroke outcomes and reduce the risk for recurrent stroke. Secondary stroke prevention guidelines recommend screening for diabetes following a stroke. The diabetes medications pioglitazone and glucagon-like peptide-1 receptor agonists have demonstrated protection against stroke in randomized controlled trials; this protective effect is believed to be independent of glycemic control. Neurologists are often involved in the management of modifiable risk factors for stroke (including hypertension, hyperlipidemia, and atrial fibrillation), but less often in the direct management of diabetes. This review provides an overview of the relationships between diabetes and stroke, including epidemiology, pathophysiology, post-stroke outcomes, and treatments for people with stroke and diabetes. This should aid neurologists in diabetes-related decision-making when treating people with acute or recurrent stroke.

Replantation of fingers is highly complex and technically challenging. Surgeons are serious with their selection criteria as many factors are involved in determining good surgical outcome. Improper storages of amputated parts are usually denied the option for replantation. We report a 42-year-old lady who was assaulted with a machete and presented with total amputation of left thumb. The amputated thumb was stored in a plastic bag directly on ice cubes which eventually melted; thumb immersed in water for two hours. On examination, the amputated thumb was neither macerated nor frozen. Replantation was attempted and was successful. There are limited reports on proper methods of storage of amputated fingers pertaining to daily practical scenario. Yet, it is a strict criterion for surgeons in attempting replantation. Direct contact of amputated fingers on ice and immersion in hypotonic solutions leads to irreversible tissue damage. In our case, two hours of unfavourable storage did not affect surgical outcome. In conclusion, clinical assessment of the amputated part is essential in deciding for replantation. Combination of direct contact with ice and immersion in hypotonic solution for two hours should not be a contraindication for replantation.

BACKGROUND: The Sensory Processing and Self-Regulation Checklist (SPSRC) is a parent or caregiver-reported instrument that measures a child’s self-regulation and sensory processing ability as they perform daily activities. The original version in Chinese and a more recent English version has reported favorable reliability and validity. While the SPSRC has undergone translation into a Tagalog version, its psychometric properties are unknown. OBJECTIVES: This study aims to examine the psychometric properties of the SPSRC-Tagalog. METHODS: Reliability and validity properties were tested among a sample of Filipino children with (n= 45) and without disability (n= 45), based on the reports of the parents or caregivers on the SPSRC-Tagalog. RESULTS: This study found that the SPSRC-Tagalog has good internal consistency, excellent test-retest reliability, and good crosscultural, discriminant, structural, construct, and criterion validity. CONCLUSION The psychometric properties of the SPSRC-Tagalog corroborate with its other language versions in its reliability and validity to measure the sensory processing and self-regulation abilities in Filipino children with and without a disability. The information obtained from the SPSRC-Tagalog may be useful in informing our understanding of sensory processing difficulties among children.

Introduction: Post-implantation rod deformation is anticipated in scoliosis surgery but the difference in rod deformation between titanium and cobalt chrome rod has not been elucidated. This study aims to compare the difference in rod deformation between two groups. Materials and Methods: Twenty-one adolescent idiopathic scoliosis (AIS) patients were recruited from a single center. The over-contoured concave rods were traced prior to insertion. Post-operative sagittal rod shape was determined from lateral radiographs. Rod deformation was determined using maximal rod deflection and angle of the tangents to rod end points. The differences between pre- and post-operative rod contour were analysed statistically. Rod deformation and thoracic kyphosis between two types of implants were analysed. Results:Both rods exhibited significant change of rod angle and deflection post-operatively. Curvature of the titanium rod and cobalt chrome rod decreased from 60.5° to 37°, and 51° to 28° respectively. Deflection of titanium rod and cobalt chrome rod reduced from 28mm to 23.5mm and 30mm to 17mm respectively. There was no significant difference between titanium and cobalt chrome groups with regard to rod angle (p=0.173) and deflection (p=0.654). Thoracic kyphosis was increased from 20° to 26° in titanium group but a reduction from 25° to 23° was noticed in cobalt chrome group, but these findings were not statistically significant. Conclusion: There was no statistical difference in rod deformation between the two groups. Thus, the use of titanium rod in correction of sagittal profile is not inferior in outcome compared with cobalt chrome but with lower cost.

The cochlea of children with congenital sensorineural hearing loss with normal inner ear structure was measured and analyzed by high-resolution temporal bone CT(HRCT) imaging technique,its application value before cochlear implantation was evaluated and the appropriate electrode was selected.We collected temporal bone HRCT images of 120 patients with congenital sensorineural hearing loss,according to gender divided into two groups,including 60 males and 60 females.We used the PACS software to measure the distance A(the largest distance from the round window to the lateral wall) and the distance H(height of the cochlea) and calculate the cochlear duct length. Reproducibility of these data were evaluated and the results between the different groups were compared.Measurement of parameter values between the intraobserver and interobserver showed great reproducibility. In the male children group,the measured values are shown as distance A［(8.55±0.31)mm］,distance H［(4.57±0.28)mm］and the cochlear duct length(CDL)［(27.59±1.23)mm］; and in the female children group, the measured values are shown as distance A［(8.45±0.32)mm］,distance H［(4.42±0.34)mm］and the cochlear duct length(CDL)［(27.20±1.17)mm.The A,H,and CDL of the male cochlea were greater than those of the female, the difference was statistically significant(<0.05).Measuring the distance A and distance H of the cochlea and calculating the cochlear duct length CDL can be used to select a suitable length of electrode or to customize a personalized electrode. This is a simple and effective assessment method before cochlear implantation..

INTRODUCTION: Respiratory virus (RV) infections have been implicated in acute exacerbation cardiopulmunary conditions. This study aimed to determine the prevalence of RV infections in patients admitted to the cardiology unit with acute decompensated heart failure (ADHF) in a tertiary hospitals in Singapore. MATERIALS AND METHODS: This was a single-centre, prospective observational study. A total of 194 adults (aged >21) admitted to the Singapore General Hospital with ADHF were recruited. A nasopharyngeal swab was taken for multiplex polymerase chain reaction (PCR) detection of influenza virus, rhinovirus, parainfluenza virus (HPIV), human coronavirus (HcoV), adenoviurs, human bocavirus (HboV), human metapneumovirus (hMPV), and respiratory syncytial virus (RSV). RESULTS: Twenty-five (13%) had RVs detected by RV multiplex PCR. There comprised 9 rhinoviruses (36%), 4 influenza A viruses (16%), 3 HPIV (12%), 3 HCoV (12%), 2 adenoviruses (8%), 1 human HBoV (4%), 1 hMPV (4%), and 1 RSV (4%). Symptoms-wise, cough was significantly more common in the PCR-positive group (48% vs 24%, = 0.02). There were no statistically significant differences in laboratory investigations (haemoglobin, leukocytes, platelets, creatine kinase, creatine kinase-muscle/brain, troponin T), and radiology findings between RV PCR-positive and -negative groups. The PCR-positive group did not have increased mortality or length of hospital stay. CONCLUSION This study identified a considerable burden of RVs in our ADHF cohort, and highlights the need for prevention of RVs in this group of patients. We also recognised the difficulty with clinical diagnosis of RVs in ADHF patients.
