Fulltext Attitudes and perceptions of the general Malaysian public regarding family presence during resuscitation

Chew KS, Ghani ZA

Singapore Med J, 2014 Aug;55(8):439-42.
PMID: 25189307

INTRODUCTION: Family presence (FP) during resuscitation is an increasingly favoured trend, as it affords many benefits to the critically ill patient's family members. However, a previously conducted study showed that only 15.8% of surveyed Malaysian healthcare staff supported FP during resuscitation.

METHODS: This cross-sectional study used a bilingual self-administered questionnaire to examine the attitudes and perceptions of the general Malaysian public toward the presence of family members during resuscitation of their loved ones. The questionnaires were randomly distributed to Malaysians in three different states and in the federal territory of Kuala Lumpur.

RESULTS: Out of a total of 190 survey forms distributed, 184 responses were included for analysis. Of the 184 respondents, 140 (76.1%) indicated that they favoured FP during resuscitation. The most common reason cited was that FP during resuscitation provides family members with the assurance that everything possible had been done for their loved ones (n = 157, 85.3%). Respondents who had terminal illnesses were more likely to favour FP during resuscitation than those who did not, and this was statistically significant (95.0% vs. 73.8%; p = 0.04).

CONCLUSION: FP during resuscitation was favoured by a higher percentage of the general Malaysian public as compared to Malaysian healthcare staff. This could be due to differences in concerns regarding the resuscitation process between members of the public and healthcare staff.

Dent Res J (Isfahan), 2018 6 21;15(3):215-219.
PMID: 29922341

Background: Composite resin (CR) currently is one of the most commonly used material in restoring noncarious cervical lesions (NCCL) due to its strength and esthetics color but has microleakage problem. The aim of this study is to compare in vitro the microleakage depth between CR and porcelain in restoring NCCL.
Materials and Methods: This an in vitro study was done by preparing cavities on the buccocervical surface of 62 extracted premolar teeth which randomly assigned to two groups (n = 31) where Group 1 was restored with nanocomposite and Group 2 was cemented with porcelain cervical inlays. They were then subjected to thermocycling before immersion in 2% methylene blue dye for 24 h. Dye penetration depths were measured using Leica imaging system For statistical analysis, independent t-test was used to analyze the results (P < 0.05).
Results: Porcelain cervical inlay restorations demonstrated statistically lesser microleakage depth for the cervical margins (P = 0.018) when compared to CR. Deeper microleakage depth at the cervical compared to coronal margins of CR (P = 0.006) but no significant difference of both margins for porcelain cervical inlays (P = 0.600).
Conclusion: Porcelain cervical inlays show lesser microleakage than CR which could be alternative treatment option in restoring NCCL with better marginal seal and esthetics.

Despite growing number of intraocular lens power calculation formulas, there is no evidence that these formulas have good predictive accuracy in pediatric, whose eyes are still undergoing rapid growth and refractive changes. This study is intended to compare the prediction error and the accuracy of predictability of intraocular lens power calculation in pediatric patients at 3 month post cataract surgery with primary implantation of an intraocular lens using SRK II versus Pediatric IOL Calculator for pediatric intraocular lens calculation. Pediatric IOL Calculator is a modification of SRK II using Holladay algorithm. This program attempts to predict the refraction of a pseudophakic child as he grows, using a Holladay algorithm model. This model is based on refraction measurements of pediatric aphakic eyes. Pediatric IOL Calculator uses computer software for intraocular lens calculation.

PMID: 33969123 DOI: 10.1155/2021/6674400

The objective of this paper was to evaluate the existence of golden percentage in natural maxillary anterior teeth with the aid of 3D digital dental models and 2D photographs. And to propose regional values of golden percentage for restoration of maxillary anterior teeth. For this purpose, one hundred and ninety dentate subjects with sound maxillary anterior teeth were selected. Standardized frontal images were captured with DSLR, and the apparent width of maxillary anterior teeth was measured utilizing a software on a personal laptop computer. Once the dimensions were recorded, the calculations were made according to the golden percentage theory (GPT). The data were analyzed by independent and paired T-test. The level of significance was set at p < 0.05. The golden percentage values were not found in this study. The values obtained were 16%, 15%, 20%, 20%, 15%, and 16% moving from the right canine to the left canine teeth. There was no significant gender difference in the golden percentage values. Thus, golden percentage should not be used solely for the correction of anterior teeth or for determining dental attractiveness. Emphasis should be given to a range of dental proportion on regional basis.

STATEMENT OF PROBLEM: The color and form of teeth are 2 of the 3 main determinants of success in an esthetic restoration; the third is dental proportion. A recent systematic review of the literature devoted to the evaluation of dental proportion is lacking.
PURPOSE: The purpose of this systematic review was to investigate the quality and outcome of studies into maxillary anterior tooth proportion and to determine whether dental proportion ratios based on different geographic regions are appropriate.
MATERIAL AND METHODS: An electronic search was conducted using PubMed, MEDLINE, Google Scholar, Embase, Scopus, Cochrane Library, Web of Science, and Science Direct databases. English-language articles reporting with the specific combination of medical subject heading (MeSH) key words were analyzed by 2 investigators. The titles, full text, and abstracts were scanned by investigators independently to identify articles that fulfilled the inclusion criteria. The general characteristics, outcomes, and quality of each study were reviewed and analyzed systematically.
RESULTS: The search plan resulted in a total of 73 articles until September 2020; of which, 16 articles fulfilling the inclusion criteria were selected. The geographic distribution of the selected article revealed 12 articles from Asia, 2 from Continental Europe, and 2 from the United Kingdom. Golden percentage values of 25%, 15%, and 10% for central, lateral incisor, and canine teeth were not found. The mean predicted dental percentage was either larger or smaller than the successive widths of maxillary natural anterior teeth.
CONCLUSIONS: The golden percentage could not be used to formulate a smile design. Rather, the dental ratios should be set on a racial and ethnic basis for a population.

This study determined the optimum conditions for preparation and adsorptive treatment of landfill leachate from banana pseudo-stem based activated carbon. Response surface methodology (RSM) based on Box-Behnken was applied to optimize the combination effect of three important reaction variables, i.e. activation temperature (°C), activation time and impregnation ratio (IR). The reaction was performed via a single step activation with ZnCl2 in a closed activation system. A series of 17 individual experiments were conducted and the results showed that the RSM based on BBD is very applicable for adsorptive removal of pollutants from landfill leachate treatment. The optimum conditions obtained by Design of Experiments (DOE) was at 761°C activation temperature, 87min activation time and 4.5g/g impregnation ratio with product yield (27%), iodine number (1101mg/g), color removal (91.2%) and COD removal (83.0%).

This study aims to describe the epidemiology of ocular burns and related injuries due to fireworks during the Aidil Fitri celebration on the East Coast of the Peninsular Malaysia. A prospective analysis of all patients with ocular burns and related injuries due to fireworks attended three tertiary hospitals in East Coast of Peninsular Malaysia during Aidil Fitri, which was from 10 September to 17 October 2008. We observed the demographic and injury characteristics, extent of the injuries and presenting visual symptoms. Thirty patients with 34 eyes with ocular burns and related injuries were identified. Patients ranged between 2 and 43 years of age. 70.00% of the patients were 12 years old and below. Of the 30 patients, 29 (96.67%) were male and the left eye was affected in 14 (46.70%). Thermal injuries accounted for 60.0% of the injuries whereas 40.0% were due to exploding firework. Burns to the eyelid and cornea (35.29%) were the most common injuries noted. Fifteen patients (50%) were bystanders whilst a majority of patients (96.67%) had no eye protection. At presentation, 15 (44.12%) eyes had a visual acuity of 6/6 to 6/9 in the injured eyes, while 3 out of 34 eyes (8.82%) had vision acuity 6/60 or worse. In conclusion, fireworks cause serious preventable ocular burns and related injuries especially in children who are the most affected age group. It affects mainly eyelid and anterior segment structures which result in moderate visual loss on presentation. Health education, public awareness and tighter legislation are essential preventive measures to limit the effect of fireworks to the public.
