Integrated approach of naqli and aqli knowledge is applied in most educational
activities conducted in Faculty of Dentistry, Universiti Sains Islam Malaysia (USIM). Naqli is
knowledge from al-Quran and as-Sunnah while aqli is rational knowledge or knowledge based on
scientific evidence. Currently the integration of naqli and aqli knowledge in periodontology subject
is at the initial stage of implementation. Motivational session for periodontitis patients is identified
to be one of the educational activities that integrates the naqli and aqli knowledge. Therefore, this
study is aimed to identify elements of naqli knowledge that can be included during motivational
session in periodontal clinic. (Copied from article).
Introduction: Transposition is a rare dental anomaly in positional interchange between two adjacent teeth. Studies indicated that tooth transpositions are more frequent unilateral than bilateral (12:1). It is a very rare phenomenon when the anomaly is bilateral and affects same teeth on both sides. The case of a 17 year old girl, with class I incisor relationship on class 1 skeletal base with bilateral transposition of maxillary canines-first premolars, severe crowding and posterior crossbite, is presented. This case report demonstrates the orthodontic management of bilateral transposition of maxillary canines-first premolars and by the end of treatment, the transpositions were maintained while achieving a good functional and aesthetic result.
KEYWORDS: transposition, maxillary canine, malocclusion
Introduction: Smoking is a well-known cause of oral disease and oral cancer. Several dysplastic cytological changes occur before the appearance of the clinical lesion. This study aimed to investigate the cytopathological effects of smoking in clinically normal oral mucosa of cigarette smokers.
Materials and Methods: A total of 40 cigarette smokers and 40 nonsmokers (control group) were included in this study. All participants had clinically normal oral mucosa. Oral smears were obtained from the side of the tongue and floor of the mouth using a Cytobrush. The smears were stained by Papanicolaou stain and examined under light microscope for inflammation, hyperkeratinization and dysplasia.
Results: There was a significantly higher rate(p<0.005) of inflammation 63%, hyperkeratiniztion 62% and mild dysplasia 26% among smokers than non-smokers where the rates were 35%, 12% and 2% respectively.
Conclusion: Smoking causes significant cytopathological changes in normal oral mucosa, the detection of which is important to prevent progression into carcinoma. The procedure is fast, painless and inexpensive.
KEYWORDS: Papanicolaou stain, brush biopsy, cigarette smokers, dysplasia, oral mucosa
Copy denture technique is a classic technique for construction of a new denture
based on the favourable aspects of the original denture using a replica. This technique helps in
adaptation of new denture in elderly population. The aim of this paper was to assess the knowledge
and practice of copy denture technique among dentists and dental technologists. (Copied from article).
Non-syndromic tooth agenesis defined as developmental absence of more than one
tooth that appears as independent congenital oral trait. Its prevalence, pattern and distribution
rates vary by populations. The aim of this study was to identify the pattern and distribution of
tooth agenesis in permanent dentition among IIUM dental polyclinic patients. (Copied from article).
The skeletal remains of Late Pleistocene-early Holocene humans are exceptionally rare in island Southeast Asia. As a result, the identity and physical adaptations of the early inhabitants of the region are poorly known. One archaeological locality that has historically been important for understanding the peopling of island Southeast Asia is the Niah Caves in the northeast of Borneo. Here we present the results of direct Uranium-series dating and the first published descriptions of three partial human mandibles from the West Mouth of the Niah Caves recovered during excavations by the Harrissons in 1957. One of them (mandible E/B1 100") is somewhat younger than the 'Deep Skull' with a best dating estimate of c30-28 ka (at 2σ), while the other two mandibles (D/N5 42-48" and E/W 33 24-36") are dated to a minimum of c11.0-10.5 ka (at 2σ) and c10.0-9.0 ka (at 2σ). Jaw E/B1 100" is unusually small and robust compared with other Late Pleistocene mandibles suggesting that it may have been ontogenetically altered through masticatory strain under a model of phenotypic plasticity. Possible dietary causes could include the consumption of tough or dried meats or palm plants, behaviours which have been documented previously in the archaeological record of the Niah Caves. Our work suggests a long history back to before the LGM of economic strategies involving the exploitation of raw plant foods or perhaps dried and stored meat resources. This offers new insights into the economic strategies of Late Pleistocene-early Holocene hunter-gatherers living in, or adjacent to, tropical rainforests.
There are different types of nutritionally mediated oxidative stress sources that trigger inflammation. Much information indicates that high intakes of macronutrients can promote oxidative stress and subsequently contribute to inflammation via nuclear factor-kappa B- (NF-κB-) mediated cell signaling pathways. Dietary carbohydrates, animal-based proteins, and fats are important to highlight here because they may contribute to the long-term consequences of nutritionally mediated inflammation. Oxidative stress is a central player of metabolic ailments associated with high-carbohydrate and animal-based protein diets and excessive fat consumption. Obesity has become an epidemic and represents the major risk factor for several chronic diseases, including diabetes, cardiovascular disease (CVD), and cancer. However, the molecular mechanisms of nutritionally mediated oxidative stress are complex and poorly understood. Therefore, this review aimed to explore how dietary choices exacerbate or dampen the oxidative stress and inflammation. We also discussed the implications of oxidative stress in the adipocyte and glucose metabolism and obesity-associated noncommunicable diseases (NCDs). Taken together, a better understanding of the role of oxidative stress in obesity and the development of obesity-related NCDs would provide a useful approach. This is because oxidative stress can be mediated by both extrinsic and intrinsic factors, hence providing a plausible means for the prevention of metabolic disorders.
Phyllodes tumour is a rare entity, affecting mainly middle aged women. It consists of a spectrum of disease
from benign tumour to highly aggressive malignant form. We present a case of massive ruptured malignant
Phyllodes tumour, and its subsequent management.
Bilateral clavicle fractures are not frequently seen. To treat these injuries surgically or non-surgically is still a debatable issue. Implant option for surgical management is also in doubt. We would like to share our experience in treating a patient with bilateral clavicle fracture surgically. He had excellent outcomes in terms of function and radiology. Surgical option for bilateral clavicle fractures promises excellent outcome in terms of early rehabilitation and return in function.
In the current study, we report a new technique to place a tunnelled peripherally inserted central catheter
(PICC) at the upper arm of patient under real-time ultrasound-guided venipuncture using disposal equipment
provided within a standard PICC set. The tunnelling of the PICC required an extra time of 5 minutes but was
well tolerated by all patients involved in the study. The tunnelled PICC was applied on 50 patients and the
infection rate as well its catheter dwell time were compared to another 50 patients with conventional PICC.
The rate of patients who developed infection decreased from 34% for conventional PICC to 16% in tunnelled
PICC patients. The central line-associated blood stream infections rate was also decreased from 4.4 per 1000
catheter-days for conventional PICC to 1.3 per 1000 catheter-days for tunnelled PICC. The mean time to infection
development for tunnelled PICC (24 days) was longer than those observed with conventional PICC (19 days).
Tunnelled PICC has also increased the mean catheter dwell time from 27 days (for conventional PICC) to 47
days. Tunnelling a PICC has the potential to reduce the infection rate while increase the catheter dwell time.
Individuals with Diabetes Mellitus (DM) are at increased risk for developing
diabetic ocular complications. This study was carried out to determine factors
influencing eye screening among Diabetes Mellitus patients. The descriptive findings of
participants’ sociodemographic data will be discussed. (Copied from article).
Currently, it is almost impossible to diagnose a patient at the onset of
sepsis due to the lack of real-time metrics with high sensitivity and specificity. The
purpose of the present study is to determine the diagnostic value of model-based insulin
sensitivity (SI) as a new sepsis biomarker in critically ill patients, and compare its
performance to classical inflammatory parameters. (Copied from article).
Patient undergoes orthodontic treatment with fixed appliances have more plaque
retentive area compare to normal person. Therefore, this patient requires higher standard of oral
hygiene care. One of adjunctive cleaning device for oral hygiene care is water irrigator. There are
several types of water irrigator available in the market such as syringe type, electricity and battery
operated. However, the problem is the available water irrigators are expensive. (Copied from article).
This paper presents a modified design of low power recovery circuit in micro-system implanted device to stimulate the human nerve and muscle. The amplitude shift keying ASK was used to modulate data by using operating frequency 6.78MHz ISM industrial scientific medical band to be less invasive to tissue. The proposed system consists of an external part which has ASK modulator and class-E power amplifier with 94.5% efficiency. The internal part has half wave rectifier and voltage regulator to generate very stable 1.8VDC using 0.35um CMOS technology. The Orcad pspice 16.6 and MULTISIM 11 software were used to simulate the design of power recovery and class-E power amplifier respectively. The regulated voltage utilised to power the sub-electronic device implanted inside human body with very stable voltage even change implanted load resistance. The proposed system has 12.5%modulation index and low power consumption.
Eagle's syndrome (ES) refers to a group of various types and patterns of pain which spans over the head-and-neck region owing to an elongated styloid process or calcified stylohyoid ligament. These symptoms are often confused with those attributed to a wide variety of facial neuralgias. The diagnosis of ES is usually made through clinical exclusion which is then confirmed radiographically. Patients with ES are initially managed with nonsurgical therapy, but surgical resection seems to be the treatment of choice. The styloid process shortening can be achieved through an intraoral or extraoral approach. This clinical case report describes such a case of ES after sustaining neck trauma.
Carbon nanotubes (CNTs) possess outstanding properties that could be useful in several technological, drug delivery, and diagnostic applications. However, their unique physical and chemical properties are hindered due to their poor solubility. This article review's the different ways and means of solubility enhancement of single-wall carbon nanotubes (SWNTs). The advantages of SWNTs over the multi-walled carbon nanotubes (MWNTs) and the method of non-covalent modification for solubility enhancement has been the key interest in this review. The review also highlights a few examples of dispersant design. The review includes some interesting utility of SWNTs being wrapped with polymer especially in biological media that could mediate proper drug delivery to target cells. Further, the use of wrapped SWNTs with phospholipids, nucleic acid, and amphiphillic polymers as biosensors is of research interest. The review aims at summarizing the developments relating to wrapped SWNTs to generate further research prospects in healthcare.
Psychotherapies were offered to alleviate psychological and physical symptoms; however, most psychological interventions were only delivered after cancer treatment. Newly diagnosed cancer patients experienced psychological distress while waiting for treatments. This review paper focused on randomized control trial studies, aimed to investigate the effectiveness of psychological intervention among newly diagnosed cancer patients. Eight randomized control trial papers were found in recent 10 year period through electronic database. A moderate to large effect size was detected on the outcomes, ranging from 0.43 to 0.89. This indicated that psychological-based prehabilitation with standard care yielded better outcomes than standard care alone. Psychological-based prehabilitation provides evidence in its effectiveness to reduce psychological distress, functional impairment, recurrence of cancer, numbers of immune reactivity and sleeping quality; however, inconsistent with longer survival result among cancer patients. In conclusion, psychological-based prehabilitation before cancer treatment is necessary for better treatment outcome, and future research is needed to investigate more directly the outcome.
