    Objectives: The objective of the study was to understand and analyze the prescription patterns of dentists across various demographic locations for managing oral infections and pain with antibiotics and explore the evidence-based practices by clinicians as well as the need for further education. Materials and methods. This cross-sectional study was carried out using an online questionnaire framed to explore the knowledge, attitude, and practices among dentists with varying levels of experience and qualifications, regarding antimicrobial prescription. The questions were validated from previous published studies that explored the knowledge, attitude, and practice (KAP) with respect to antimicrobial prescription. In total, N = 300 of dentists from four different countries responded to the online questionnaire out of which 53% were specialists while 47% were general dentists. After data collection, descriptive analysis was carried out along with a one-sided hypothesis test to depict the power of the sample.

    Results: It was seen from the results of the study that the first-choice antibiotics for 67.8% of dentists were found to be the β-lactam group while sulfonamides and tetracyclines at 20% were the second most prescribed group. Another important finding was that 45.6% of dentists ignored hypersensitivity testing before prescription of antibiotics even though 83.3% of the total dentists interviewed were aware of the increase in antibiotic resistance.

    Conclusion: In conclusion, the dentists are partially aware of the guidelines but need further training and education on antimicrobial prescription that enables evidence-based decision-making for better practices and outcomes.

    Background: Appendicitis complicated with appendiceal perforation is common among children. The delay in diagnosis of appendicitis is due to children's varied presentations and their difficulty in communicating symptoms. We aimed to identify clinical factors that aid in predicting acute appendicitis (AA) and perforated appendicitis (PA) among children.

    Methods: This retrospective study involved 215 children aged 12 years and below with the initial diagnosis of AA and PA. Clinical factors studied were demographics, presenting symptoms, body temperature on admission (BTOA), white cell count (WCC), absolute neutrophil count (ANC), platelet count and urinalysis. Simple and multiple logistic regressions were used to determine the odds ratio of the statistically significant clinical factors. Results: The mean age of the included children was 7.98 ± 2.37 years. The odds of AA increased by 2.177 times when the age was ≥ 8 years (P = 0.022), 2.380 times when duration of symptoms ≥ 2 days (P = 0.011), 2.447 times with right iliac fossa (RIF) pain (P = 0.007), 2.268 times when BTOA ≥ 38 °C (P = 0.020) and 2.382 times when neutrophil percentage was ≥ 76% (P = 0.045). It decreased by 0.409 times with non-RIF pain (P = 0.007). The odds of PA was increased by 4.672 times when duration of symptoms ≥ 2 days (P = 0.005), 3.611 times when BTOA ≥ 38 °C (P = 0.015) and 3.678 times when neutrophil percentage ≥ 76% (P = 0.016). There was no significant correlation between WCC and ANC with AA and PA.

    Conclusion: Older children with longer duration of symptoms, RIF pain and higher BTOA are more likely to have appendicitis. The risk of appendiceal perforation increases with longer duration of symptoms and higher BTOA.

    This An Ergonomic hazard often exists in any industry. However, majority of the employees are not aware of practicing good body posture until the MSDs symptoms become permanent and chronic. The main objective of this study is to determine the manual handling problems among workers at an electronic component manufacturing company. The scope of this study focused on the study entire body disorders among workers on electronic manufacturing company using the Rapid Entire Body Assessment (REBA). A cross sectional study involving observation of the workplace, the work task and the working environment, photographs and videos taken during the observation. Later, a survey questionnaire was given to the respondents to obtain their socio-demography information, work activity and health problems. Rapid Entire Body Assessment (REBA) was conducted on all respondents to determined REBA scores in different work positions. The study was conducted at an electronic component manufacturing company located in Klang Valley, Selangor. A total of 124 workers were surveyed and REBA assessment was performed on 20 workers at Company X production area. It includes 5 categories of position at Company X, such as:loading steel bar into casing; pushing the steel bar, turning movement while adjusting the steel bar, adjusting steel bar into the loading area, unloading steel bar from casing into the machine. The study found that turning section has the highest MSDs problems regarding manual handling because majority of the respondents in the turning department felt the pain while performing their work. This is due to their job demand, which they need to handle with tools weighing from 200 to 400 kg. The REBA scores showed that17 out of 20 respondents performing turning operations, moving and pushing the steel bar recorded the highest score of 11 or more which are categorize in the very high risk group. The position of pushing and turning steel bar while moving the steel bar has higher risk that contributed to the ergonomics risk factor, which in-turn can contribute to Muscular Skeletal Disorders (MSDs). More detailed investigation and remedial measures should be taken immediately, especially for the workers performing the manual handlings activities.

    Introduction: Tropical phagedenic ulcer is a skin disease caused by a cocktail of bacteria. This painful ulcer forms over the lower limbs. It is also associated with necrotic slough and foul-smelling discharge that eventually lead to amputation and permanent disabilities. Tropical phagedenic ulcer in Malaysia has not been given much attention. In light of this situation, this research was conducted to assess the knowledge, attitude and practice regarding tropical phagedenic ulcer among the public in Shah Alam, Selangor. Methods: The total respondents were 384, consisting of 164 males and 220 females who were randomly selected. Data were obtained qualitatively through structured questionnaires and analysed using the chi-square test to study the association between the dependent variables and demographic factors. Results: The collected data showed that the respondents (67.2%) had poor knowledge of trop- ical phagedenic ulcer; merely 65.4% considered it to be a health problem, whereas 29.7% believed it is contagious. Also, the data revealed an association between age (χ2=13.587, p =0.004), marital status (χ2=15.435, p=0.001), time spent in community (χ2=6.438, p=0.04) and knowledge of the local name of tropical phagedenic ulcer. About 74.7% of the respondents did not know the cause of tropical phagedenic ulcer. Only 22.1% of the respondents had encoun- tered tropical phagedenic ulcer patients and an association was found between the variable with gender (χ2=4.672, p =0.031), age (χ2=24.134, p =0.000) and marital status (χ2=17.143, p =0.001). Conclusion: This study reveals mis- conceptions about the aetiology and transmission of tropical phagedenic ulcer which greatly influence the attitude of community members towards tropical phagedenic ulcer patients.

    Our purpose is to report on the epidemiological variables and their association with the results of the exercise tolerance test (ETT) in the series of patients referred for standard diagnostic ETT at Seremban Hospital during the year 2001. ETT is widely performed, but, in Malaysia, an analysis of the associations between the epidemiological data and the results of the ETT has not been presented. All patients referred for ETT at Seremban Hospital who underwent exercise treadmill tests for the year 2001 were taken as the study population. Demographic details and patients with established heart disease (i.e. prior coronary bypass surgery, myocardial infarction, or congestive heart failure) were noted. Clinical and ETT variables were collected retrospectively from the hospital records. Testing and data management were performed in a standardized fashion with a computer-assisted protocol. This study showed that there was no significant predictive epidemiological variable on the results of the ETT. However, it was found that there was statistically significant difference between the peak exercise time of males and females undergoing the ETT.

    This is a follow-up study to assess the socio demographic profile of a sample of 28,605 women seeking pregnancy terminations at a private clinic in Penang over a seven year period as compared to an earlier study in 1995 of a sample of 23,986 women over a six and a half year period at the same clinic. This study was conducted using computerized patient medical records and paper reports generated from the computer data. The earlier 1995 study showed that the profile of a typical abortion client was a Chinese (60%), housewife (45%) in her late twenties (47%) with a monthly household income of less than RM1,200 (58%), having her first abortion (51%) and who had used contraception before (78%). For the seven year period from 1998-2005, the follow-up profile of a woman seeking an abortion in the same clinic in urban Malaysia was one with a monthly household income of less than RM2,000 (100%) in her late twenties (54%) who had used contraception in the past (85%). It is noted that the percentage of Malay respondents has increased (34%). The percentage of women who had a prior abortion at this clinic or elsewhere has also increased (68%), as compared to the preliminary study. Non-use of contraception remained an issue and traditional methods still outweighed the use of more effective contraceptive methods. In conclusion, fewer housewives and more Malay and Indonesian factory workers contributed to the clinic client profile over these seven years compared to that of the earlier study in 1995.

    A canonical/lognormal model for human demography is established, specifying the net maternity function and the age distribution for mothers of new-borns using a single macroscopic parameter vector of dimension five. The age distribution of mothers is canonical, while the net maternity function normalizes to a lognormal density. Comparison of an actual population with the model serves to identify anomalies in the population which may be indicative of phase transitions or influences from levels outside the demographic. Tracking the time development of the parameter vector may be used to predict the future state of a population, or to interpolate for data missing from the record. In accordance with classical theoretical considerations of Backman, Prigogine, et al., it emerges that the logarithm of a mother's age is the most fundamental time variable for demographic purposes.

    BACKGROUND/OBJECTIVE: Postoperative pancreatic fistula (POPF) remains an important cause of morbidity and mortality after pancreaticoduodenectomy. Pancreaticogastrostomy (PG) as a reconstruction method after pancreaticoduodenectomy is a safe and optional surgical technique in decreasing the risk of POPF. In this study, a retrospective analysis was carried out to evaluate a new modification of PG technique that uses a two-layer anastomoses with an internal stent.

    METHODS: Forty-seven patients underwent this newly modified PG technique between February 2012 and August 2016. Demographics, histopathological findings, type of surgery performed, perioperative parameters, postoperative length of stay, postoperative complications and interventional procedures, follow-up, and mortality data were collected and analyzed. Clavien-Dindo classification was used to grade the complications' severity.

    RESULTS: Postoperative mortality was 4.25%, unrelated to POPF, and postoperative morbidity was 44.68%. Thirteen patients had severe (>Grade IIIa) complications, according to Clavien-Dindo classification. As classified in accordance to the International Study Group of Pancreatic Fistula, 24 (51.06%) patients developed Grade A POPF, and no occurrence of Grade B/C POPF was noted. All patients recovered uneventfully with successful treatment interventions.

    CONCLUSION: The reported PG anastomotic technique is a safe and dependable reconstruction procedure with acceptable morbidity and mortality.

    The prevalence of oral mucosal lesions in Malaysia was determined by examining a representative sample of 11,707 subjects aged 25 years and above throughout the 14 states over a period of 5 months during 1993/1994. A two-stage stratified random sampling was undertaken. A predetermined number of enumeration blocks, the smallest population unit in the census publication, was selected from each state. With the selected enumeration block, a systematic sample of living quarters was chosen with a random start. The survey instrument included a questionnaire on sociodemographic characteristics and a clinical examination. The clinical examination was carried out by 16 specially trained dental public health officers and the diagnosis calibrated with a final concordance rate of 92%. The age in the sample ranged from 25 to 115 years with a mean of 44.5+/-14.0. The sample comprised 40.2% males and 59.8% females; 55.8% were Malays, 29.4% Chinese, 10.0% Indians and 1.2% other ethnic groups. Oral mucosal lesions were detected in 1131 (9.7%) subjects, 5 (0.04%) had oral cancer, 165 (1.4%) had lesions or conditions that may be precancerous (leukoplakia, erythroplakia, submucous fibrosis and lichen planus) and 187 (1.6%) had betel chewer's mucosa. The prevalence of oral precancer was highest amongst Indians (4.0%) and other Bumiputras (the indigenous people of Sabah and Sarawak) (2.5%) while the lowest prevalence was amongst the Chinese (0.5%).

    A new insular species Cnemaspis bidongensis sp. nov. (Squamata: Gekkonidae), is described from Pulau Bidong, Terengganu, Peninsular Malaysia and bears a unique suite of morphological and color pattern characters that differentiate it from all other congeners. Cnemaspis bidongensis sp. nov. is the sister species to C. kendallii (Gray) and represents the fifth insular endemic species of Cnemaspis on archipelagos along the east coast of Peninsular Malaysia. This species survived massive deforestation of the small island of Bidong (260 ha) from the mid 1970s to the early 1990s when the island served as a Vietnamese refugee camp and harbored as many as 40,000 people at one time. We hypothesize that this species' generalized lifestyle contributed to its survival, allowing it to seek refuge in rocky microhabitats.

    A new species of Bent-toed Gecko Cyrtodactylus guakanthanensis sp. nov. of the C. sworderi complex is described from a limestone forest in Perak, Peninsular Malaysia whose karst formations at the type locality are within an active quarry. Cyrtodactylus guakanthanensis sp. nov. can be distinguished from all other Sundaland species by having the following suite of character states: adult SVL 77.7-82.2 mm; moderately sized, conical, weakly keeled, body tubercles; tubercles present on occiput, nape, and limbs, and extend posteriorly beyond base of tail; 37-44 ventral scales; no transversely enlarged, median, subcaudal scales; proximal subdigital lamellae transversely expanded; 19-21 subdigital lamellae on fourth toe; abrupt transition between posterior and ventral femoral scales; enlarged femoral scales; no femoral or precloacal pores; precloacal groove absent; wide, dark postorbital stripes from each eye extending posteriorly to the anterior margin of the shoulder region thence forming a transverse band across the anterior margin of the shoulder region; and body bearing five (rarely four) wide, bold, dark bands. Destruction of the karst microhabitat and surrounding limestone forest will extirpate this new species from the type locality and perhaps drive it to complete extinction given that it appears to be restricted to the particular microhabitat structure of the type locality and is not widely distributed throughout the karst formations. As with plants and invertebrates, limestone forests are proving to be significant areas of high herpetological endemism and should be afforded special conservation status rather than turned into cement.
