Tooth discolouration is a common problem and affects people of all ages. Apart from the conventional treatment modalities for the same, newer options are available today with better techniques and materials. The present case report describes a 17-year-old girl who had stained and pitted teeth, attributable to dental fluorosis and she desired aesthetic treatment for the same. The pros and cons of all treatment options were carefully weighed and a multistep treatment process involving ceramic veneers and direct bonding were planned. The execution of the planned treatment yielded a good aesthetic and functional outcome.
Four hundred and one cases of ameloblastoma of the jaw diagnosed in the Division of Stomatology, Institute for Medical Research, Kuala Lumpur, between 1967 and 1991 have been analysed. There were 214 males and 187 females. Of these, 50.1% were Malays, 34.7% Chinese, 8.2% Indians and 7.0% other races. Seventy-two percent of patients were in the second, third and fourth decades of life (mean age: 30.8 years). Ninety-three percent of tumours occurred in the mandible and 6.5% in the maxilla. There were 337 cases of conventional ameloblastoma, 49 cases of the unicystic variant and four cases of peripheral ameloblastoma. The predominant histologic patterns were plexiform (34.2%), follicular (16.5%) and mixture of both (17.7%). Majority of the cases were conservatively treated by enucleation. Fifty-nine cases presented with recurrences. Present findings were generally compatible with regional serial studies reported from Thailand, Singapore and Japan.
A study is made of the accuracy and repeatability of the Humphrey autorefractor (HAR) objective refraction for different refractive groups as measured against subjective refraction. The value of the autofogging mechanism in objective refraction for different refractive groupings is assessed.
Thirty-one (31) patients undergoing electroconvulsive therapy (ECT) over a three-week period in October 1982 in the Psychiatric Unit, University Hospital, Kuala Lumpur, were studied. The main indications for ECT in these patients were poor response to drug therapy, depression with suicidal ideation, and aggression, which together accounted for 87 percent of all patients started on ECT during this period. The majority of patients (86 percent) showed some improvement, and 73 percent improved by the third ECT. The most common side-effects experienced by patients were memory disturbance (45 percent) and post ECT headache (45 percent). No serious side-effects were encountered.
Forty nine patients with sick sinus syndrome seen at the University Hospital, Kuala Lumpur are reviewed. The ages of patients ranged from 17 to 85 years. There were 21 males and 28 females. The diagnostic criteria were sinus bradycardia in 8 patients (Group I), sinus arrest or sinoatrial block in 24 patients. (Group Il), and bradycardia tachycardia syndrome in 17 patiens (Group Ill). The aetiology was unknown in the majority of patients. Ischaemic heart disease was the commonest known aetiological factor. Patients with symptomatic sinus bradycardia and sinus arrest were initially treated with oral isoprenaline, and if this failed, they were paced. Temporary transvenous pacing was necessary in 27 patients and subsequent permanent pacing performed on 23 patients.
Early-onset periodontitis in children, teenagers and young adults is quite rare. This form of periodontitis progresses very rapidly and cause massive destruction to the periodontium. Various names have been given to this condition since it was first recognised in the 1920s. Through time the nomenclature changed from one to the other. Currently 3 forms of early-onset periodontitis are recognised--i.e. prepubertal periodontitis (PPP), localised juvenile periodontitis (LJP) and rapidly progressive periodontitis (RPP). The clinical features of juvenile periodontitis as it was first described together with that of the present 3 clinical entities mentioned above are presented. Concepts on the aetiology of the disease have also changed through time, and include degenerative process, bacterial infection, defects in the host defense system and heredity. Current thought is that there is an interplay of most of these factors in pathogenesis of the disease. Treatment modalities changed too. At the moment, comprehensive periodontal therapy with meticulous oral hygiene measures seem to be the treatment of choice. Concurrently, systemic tetracycline administration might have some added benefits.
This is a case report of a patient with a stab injury into the heart. It highlights the successful management in view of the limited facilities and personnel in a district hospital. This may probably be the first operation of its kind in the country.
Thirty one cases of malignant tumours of the maxillary sinus presenting to the Department of Otolaryngology, Universiti Kebangsaan Malaysia over a four year period from 1982 to 1986 are reviewed. 18 cases (58.1%) were squamous cell carcinoma while seven cases (22.5%) were Non-Hodgkin's lymphoma. There were four cases (12.0%) of adenoid cystic carcinoma while in two cases (6.5%) the tumours were undifferentiated. Presentation was generally late. Nasal obstruction, facial swelling and epistaxis were the main presenting symptoms. Nasal involvement was found in 61.3% of cases, while 51.6% had involvement of the palate as well. Metastasis to the cervical lymph node were uncommon (6.5%). Surgery and radiotherapy with or without chemotherapy were the main modes of treatment in the management of malignant tumours of the maxillary sinus.
Acute dacroadenitis is a rare condition. This case illustrates the acute onset, typical pain and tenderness in the upper outer eye of an enlarged lacrimal gland with purulent discharge. Good response to antibiotics is usual.
This study investigates the effectiveness of the school-based Shine Through Any Roadblocks (STAR) CBT intervention, by a screening conducted on 634 students from eight secondary schools in Malaysia. Participants (n = 85) who fulfilled the eligibility criteria were assigned randomly to either the intervention group (n = 42) or the assessment-only waitlist control group (n = 43). The intervention consisted of eight group-based sessions over a period of 2 months. Sessions were 60-min each and conducted according to the STAR module. Outcome measures (depressive symptoms and automatic negative thoughts) were administered at five intervals: baseline/pre-intervention, mid-intervention, post-intervention, 1-month after intervention, and 3-months after intervention. Results showed significant and lasting lower levels of depressive symptoms and automatic negative thoughts in the intervention group, indicating that the STAR intervention could be an effective means of reducing depressive symptomatology among adolescents. Clinical implications for the Malaysian secondary school context are further discussed.
Sensitive High-Resolution Ion Microprobe (SHRIMP) U-Pb analyses of zircons from Paleoarchean (~3.4 Ga) tonalite-gneiss called the Older Metamorphic Tonalitic Gneiss (OMTG) from the Champua area of the Singhbhum Craton, India, reveal 4.24-4.03 Ga xenocrystic zircons, suggesting that the OMTG records the hitherto unknown oldest precursor of Hadean age reported in India. Hf isotopic analyses of the Hadean xenocrysts yield unradiogenic 176Hf/177Hfinitial compositions (0.27995 ± 0.0009 to 0.28001 ± 0.0007; ɛHf[t] = -2.5 to -5.2) indicating that an enriched reservoir existed during Hadean eon in the Singhbhum cratonic mantle. Time integrated ɛHf[t] compositional array of the Hadean xenocrysts indicates a mafic protolith with 176Lu/177Hf ratio of ∼0.019 that was reworked during ∼4.2-4.0 Ga. This also suggests that separation of such an enriched reservoir from chondritic mantle took place at 4.5 ± 0.19 Ga. However, more radiogenic yet subchondritic compositions of ∼3.67 Ga (average 176Hf/177Hfinitial 0.28024 ± 0.00007) and ~3.4 Ga zircons (average 176Hf/177Hfinitial = 0.28053 ± 0.00003) from the same OMTG samples and two other Paleoarchean TTGs dated at ~3.4 Ga and ~3.3 Ga (average 176Hf/177Hfinitial is 0.28057 ± 0.00008 and 0.28060 ± 0.00003), respectively, corroborate that the enriched Hadean reservoir subsequently underwent mixing with mantle-derived juvenile magma during the Eo-Paleoarchean.
Purpose: To examine the relationship between sleeping quality and behavioural outcomes of UiTM Seremban 3 students.
Methods and sample: A quantitative approach using a modified questionnaire of Pittsburgh Sleep Quality Index Score was employed to examine the sleeping quality and modified version of the Adolescent Behavioral Checklist was used to obtain the response on the behavioural of UiTM Seremban 3, students. 428 respondents from three (3) faculties in the Seremban campus
participated in this study.
Findings: The result shows that there is a significant relationship between sleeping quality and behavioural outcomes of the students (r=.118, p<0.05).
Discussion and Conclusion: This study revealed that there is no significant relationship between sleeping quality and positive behavioural outcomes. However, the result indicated that there is a weak relationship between sleep quality and negative behavioural outcomes. The behaviours of the respondents tend to become
more negative if they were having poor quality of sleep. The results also suggest that poor sleep quality is not only prevalent among college students but are also associated with negative behavioural outcomes. Therefore, sleeping quality should be considered in the management of students’ health and there is a need for an investigation for possible intervention on sleeping quality of the college students.
