1.Immune Mechanism: A ‘Double-Edged Sword’
Malaysian Journal of Medical Sciences 2013;20(3):61-67
Immunology has now developed into an independent discipline in medicine which covers not only germ infection which is related to immunity solely but also covers a lot of non-infectious diseases such as autoimmune disease, allergies, and others. Therefore, “The Immune Mechanism: “a double-edged sword” means that the immune mechanism (consisted of antibody mediated mechanism and T cell mediated mechanism), just like one edge playing the role of giving benefit (immunity) as it destroys the agent of infection, and another one can be detrimental as it will cause tissue/cell damages and then give rise to immune diseases (immunopathology). Now, the prevalence of these immune diseases is on the rise and has become a new challenge to our country towards developed country in 2020. Therefore, we have to make ample preparation (laboratory facilities/services, main power, and research) from now on in order to face the problems and challenges.
2.Excision of tracheocutaneous fistula under local anaesthesia
Archives of Orofacial Sciences 2009;4(1):29-31
Tracheocutaneous fistula (TCF) is a known complication of
tracheostomy. It can cause problems such as saliva leak, predispose
to infection from external skin into respiratory tract and cosmetically
not acceptable. Treatment of the underlying infection is paramount
important. Persistence of tract after sufficient duration of observation
period should be surgically treated. Cases reported in the literature
are mainly regarding paediatric TCF and the procedures are usually
done under general anesthesia. We describe a case of surgical
treatment of an adult TCF which was done under local anaesthesia.

Background: Up to date, there are handful questionnaires that have been validated in Bahasa
Malaysia (BM). This study aimed to translate the Depression Anxiety Stress Scales 21-item
(DASS-21) and measure its psychometric properties. Objectives: To determine the construct
validity and acceptability of the DASS, BM. Methods: Two forward and backward translations
were done in BM in accordance to guideline, and its validation was determined by using
confirmatory factor analysis. A total of 263 subjects were selected by systematic random
sampling to represent Malaysian population for reliability and validity purposes. Results: The
BM DASS-21 had very good Cronbach’s alpha values of .84, .74 and .79, respectively, for
depression, anxiety and stress. In addition, it had good factor loading values for most items
(.39 to .73). Correlations among scales were between .54 and .68. Conclusions: BM DASS-21
is correctly and adequately translated to Bahasa Malaysia with high psychometric properties.
Further studies are required to support these findings.

To investigate the toxic implications of ethanolic stem bark extract of Azadirachtaindica (A. indica) at 50, 100, 200 and 300 mg/kg body weight in Wistar rats. Methods: Fifty male rats of Wistar strains were randomly grouped into five (A-E) of ten animals each. Animals in Group A (control) were orally administered 1 mL of distilled water on daily basis for 21 days while those in Groups B-E received same volume of the extract corresponding to 50, 100, 200 and 300 mg/kg body weight. Results: The extract did not significantly (P>0.05) alter the levels of albumin, total protein, red blood cells and factors relating to it whereas the white blood cell, platelets, serum triacylglycerol and high-density lipoprotein cholesterol decreased significantly (P<0.05). In contrast, the final body weights, absolute weights of the liver, kidney, lungs and heart as well as their organ-body weight ratios, serum globulins, total and conjugated bilirubin, serum cholesterol, low-density lipoprotein cholesterol and computed atherogenic index increased significantly. The spleen-body weight ratio, alkaline phosphatase, alanine and aspartate transaminases, sodium, potassium, calcium, feed and water intake were altered at specific doses. Conclusions: Overall, the alterations in the biochemical parameters of toxicity have consequential effects on the normal functioning of the organs of the animals. Therefore, the ethanolic extract of A. indica stem bark at the doses of 50, 100, 200 and 300 mg/kg body weight may not be completely safe as an oral remedy and should be taken with caution if absolutely necessary.

Objective: To investigate the phytochemical properties and the anticonvulsant potential of the ethyl acetate soluble fraction of ethanol leaf extract of Globimetula braunii, a plant used in ethnomedicine for the treatment of epilepsy.
Methods:The phytochemical screening was carried out using standard protocol while the anticonvulsant activity was studied using maximal electroshock test in chicks, pentylenetetrazole and 4-aminopyridine-induced seizures in mice.
Results: The preliminary phytochemical screening carried out on the crude ethanol extract revealed the presence of saponins, carbohydrates, flavonoids, tannins, anthraquinones and steroids. Similarly, tannins, flavonoids and steroids/terpenes were found to be present in the ethyl acetate fraction. In the pharmacological screening, 150 mg/kg of the fraction protected 83.33% of animals against pentylenetetrazole-induced seizure in mice whereas sodium valproate a standard anti-epileptic drug offered 100% protection. In the 4-aminopyridine-induced seizure model, the fraction produced a significant (P<0.05) increase in the mean onset of seizure in unprotected animals. The fraction did not exhibit a significant activity against maximal electroshock convulsion. The median lethal dose of the fraction was found to be 1261.91 mg/kg.
Conclusions:These results suggest that the ethyl acetate fraction of Globimetula braunii leaves extract possesses psychoactive compound that may be useful in the management of petit mal epilepsy and lend credence to the ethnomedical use of the plant in the management of epilepsy.

Intranasal meningoencephalocoele is a rare clinical entity especially in the adult population. It is usually a congenital anomaly but can occur as a result of traumatic head injury or increased intracranial hypertension. We report the case of 25-year-old Malay man who presented with persistent headache of one-year duration that was associated with bilateral nasal blockage and intermittent right nasal discharge. He was also treated for meningitis and previously had two episodes of closed head injuries. Investigations showed that he had an intranasal transethmoidal meningoenchepalocoele. This was successfully treated with an endoscopic excision and fistula repaired using cartilage graft and tissue glue.

Dental treatment under general anaesthesia may be needed for some children and
adolescents due to medical or behaviour problem. The objective of the study is to
identify the type of treatment that has been carried out under GA in Hospital
Universiti Sains Malaysia (HUSM). A retrospective record review study from
hospital records of dental patients (under 18 years old) receiving dental treatment
under GA from 2003 until 2007 were retrieved from the database. Information
such as the reason for GA, and the type of treatment provided was recorded in
data sheet. The data were analyzed using SPSS 12.0.1 for Windows. It was checked
and verified for errors. A total of 349 cases were treated of which 43.6% had medical
problems. Patients were mostly diagnosed to have rampant caries (77.1%) and
some of them have behavioural problems (34.4%). Treatment pattern in deciduous
dentition revealed more extraction (97.8%) as compared to restoration (75.7%)
whereas in permanent dentition more restoration was done (24.3%) as compared
to extraction (2.2%). Majority of the restorations were done using Glass Ionomer
Cements (47.5%). Biopsy (4.3%) contributed mainly to the surgery (24.1%) done
during GA. General anesthesia is necessary when dental disease is interfering with
health and general well-being of patient and it can facilitated dental treatment
allowing dentists to benefit from improved treatment conditions and provide a
higher quality of care.

The purpose of this study was to determine the sawmill workers’ knowledge, attitude and practice (KAP) in relation to noise-induced hearing loss (NIHL). A
cross-sectional study was conducted involving 83 workers from 3 factories in Kota Bharu, Kelantan. Questionnaires were distributed to obtain the socio-demography,
knowledge, attitude and practice level in relation to noise-induced hearing loss (NIHL). The weak areas identified in the knowledge section were treatment aspects
(15.5%), signs and symptoms of NIHL (20.2%) and risk factors (31%). As for attitude; the prevention aspects were the lowest (25.3%), followed by risk taking
attitude (26.2%), and causes of hearing loss (42.1%). Overall, the practice was not encouraging at all. It is important to have an education program to raise workers’
awareness and to improve their attitude and practices towards noise-induced hearing loss.

Background: Traumatic brain injury (TBI) has been associated with an acute stress response mediated by the sympathoadrenomedullary axis, which can be assessed by measuring blood glucose level.
Methods: This prospective observational study was conducted for a year in 2007 among 294 patients who had been treated for TBI in Hospital Kuala Lumpur. Patients fulfilling the set criteria were recruited into the study and data, including blood glucose level and Glasgow Outcome Score at 3-month follow-up, were collected.
Results: 294 patients were included in the study: 50 females (17.0%) and 244 males (83.0%). The majority of cases were young adult patients (mean age of 34.2 years, SD 13.0). The mean blood glucose level during admission and post-surgery were 6.26 mmol/L (SD 1.30, n = 294) and 6.66 mmol/L (SD 1.44, n = 261), respectively. Specifically, the mean admission glucose level associated with mild TBI was 5.04 mmol/L (SD 0.71); moderate TBI, 5.78 mmol/L (SD 1.02); and severe TBI, 7.04 mmol/L (SD 1.18). The mean admission glucose level associated with a poor outcome in patients with isolated TBI was 6.98 mmol/L (SD 1.21). Patients with admission glucose of 5.56 mmol/L (SD 1.21) were more likely to have a favourable outcome.
Conclusion: Mild, moderate, and severe TBI were associated with an increase in blood glucose levels during admission, and the mean increase in glucose levels is based on the severity of the isolated TBI. Surgical intervention did not cause further significant changes in blood glucose levels. Patients with isolated TBI and minimal increases in blood glucose levels were more likely to have a favourable outcome.
