RESUMO

INTRODUCTION: Tuberculosis (TB) and human immunodeficiency virus (HIV) co-infection is a global public health issue among people living with HIV. The objective was to assess the prevalence of TB treatment outcomes (successful and unsuccessful) and associated factors with TB treatment success among TB and HIV co-infected patients in Kelantan for 5 years (2014-2018). The successful TB treatment was defined as the sum of cured patients and those who completed the treatment. The unsuccessful treatment was defined as the sum of treatment failed, died, and default. MATERIALS AND METHODS: A cross-sectional study was conducted at the TB/Leprosy Unit of the State Health Department of Kelantan (JKNK) using secondary data from January 2014 to December 2018 assessed in the MyTB online system. The data were analyzed using SPSS 25.0 and STATA 14. Ethics approvals were obtained from Medical Research Ethics Committee (MREC) and UniSZA Human Research Ethics Committee (UHREC). RESULTS: Kelantan had 6,313 TB cases from January 2014 to December 2018. There were 703 (11.1%) cases of TB and HIV co-infection. The prevalence of successful treatment among TB and HIV co-infected patients was 57.1%. The duration of treatment and anatomy of TB location was significantly associated with TB treatment success. CONCLUSION: This study's findings showed that the prevalence of TB treatment success rate was 57.1%, and the unsuccessful rate was 42.9%. The treatment duration and the TB location's anatomy were significantly associated with the treatment success rate. Improving TB treatment outcomes should be started with anti-TB treatment immediately after TB diagnosis. Therefore, the government should strengthen the TB/HIV collaborative efforts to achieve good treatment outcomes among these vulnerable patients.

RESUMO

INTRODUCTION: High intakes of total fat are long known as a risk factor for coronary heart disease (CHD), but the association between fatty acids and CHD remains unclear. This scoping review aims to collate and analyze the association between types of fatty acid and risk of CHD. MATERIALS AND METHODS: This review uses the methodological framework of Arksey and O'Malley. A total of 19 studies were selected from 9456 studies screened from the electronic databases. RESULTS: Majority of the studies reported no association between saturated fat (SFA) and monounsaturated fat (MUFA) with CHD. Meanwhile, seven out of 12 studies reported inverse association between polyunsaturated fat (PUFA) and risk of CHD whilst 67% of the studies found that trans-fat intake was positively associated with CHD risk. CONCLUSIONS: This review finds that all the types of dietary fat have different effects on the risk of CHD. Nevertheless, intakes of healthy fat such as MUFA and PUFA in controlled amounts are expected to reduce CHD risk. In addition, the divergence of findings found between studies might be due to the methodological inconsistencies. More robust research is needed to determine the actual dietary determinants of CHD as it will provide important information for future development of dietary intervention.

RESUMO

OBJECTIVES: To design and develop a simple vision test algorithm for mobile application and perform a pilot study to determine its validity and reliability as a tool for vision test in the community. METHODS: A simple visual acuity test algorithm in the form of a single letter E display was designed as the optotype for development of a mobile application. The standardised optotype is presented at random to test visual acuity for corresponding level of 3/60, 6/60, 6/18, and 6/12. The final result is auto-generated based on the classification of the WHO for visual impairment and blindness. The Snellen chart was used as the gold standard to determine its validity while five different users were involved to determine its inter-rater reliability. A pilot study was performed between April till November 2019, in the Universiti Sultan Zainal Abidin Medical Centre (UMC) at Kuala Nerus and Mooris Optometrist Centre at Marang, Terengganu. A total of 279 participants aged four years old and above were involved in this study. RESULTS: The highest sensitivity was found at the vision level cut-off point of 6/12 with the percentage of 92.7% and 86.8% for the right and left eye, respectively. The specificity was more than 89% for all vision levels in both eyes. The Krippendorff's alpha value for the inter-rater reliability was 0.87 and 0.83. CONCLUSION: The relatively high level of validity and reliability obtained indicate the feasibility of using the designed optotype to develop a valid and reliable mobile app for vision test. The app can be used to screen vision by nonmedical persons, at anytime and anywhere to help improve public awareness and capability to correctly determine their visual status.

RESUMO

INTRODUCTION: Brain tumour (BT) is a tremendous burden on patients, families as well as the surrounding communities, especially the healthcare services. It can be classified into either a benign slow growing tumour (non-cancerous) and malignant tumour (cancerous). The purpose of this study was to determine the incidence and pattern of brain tumour admitted to the Neurosurgery Department in Hospital Sultanah Nurzahirah (HSNZ), Terengganu, Malaysia. METHODS: This is a retrospective study of incidence and pattern of BT admitted to the Neurosurgery Department in HSNZ. Data was collected from the yearly census of BT registered from 2013 to 2018. RESULTS: A total number of 386 new cases of primary BT were registered. The number of cases of BT was found to be lowest among children (0 to 10 years old) with only 4.4% but at peak among elderly aged between 51 to 60 years old (26.2%). As for gender, males constituted about 44.5% (n=172) whereas females accounted for 55.5% (n= 214) of the cases. In total, meningioma was found to have the highest incidence (27.2%) followed by metastases brain tumour (18.1%) and glioma (17.4%). CONCLUSIONS: This study has shown that the incidence of BT was led by meningioma which had a high prevalence among the elderly population, followed by metastasis BT and gliomas.

RESUMO

OBJECTIVE: To investigate association between major depressive disorder (MDD) and quality of life in patients with neurological disorder. METHODS: This cross-sectional study was carried out at a Malaysian hospital between April 2016 and December 2016 using convenience sampling. Patients aged ≥18 years with intracranial tumour or other brain disorders were invited to participate. Quality of life was assessed using the European Organisation for Research and Treatment of Cancer Quality of Life questionnaire version 3.0; diagnosis of MDD was made using Mini International Neuropsychiatric Interview. RESULTS: Of 122 patients approached, 100 (66 women and 34 men) were included (response rate, 93.5%), with a mean age of 45.3 years. The prevalence of MDD in patients with neurological disorder was 30%. Compared with non-depressed patients, patients with MDD had poorer global health status / quality of life (p = 0.003), and reduced physical (p = 0.003), role (p = 0.021), emotional (p < 0.001), cognitive (p = 0.004), and social (p = 0.007) functioning, as well as more symptoms of fatigue (p = 0.004), pain (p < 0.001), dyspnoea (p = 0.033), insomnia (p < 0.001), appetite loss (p = 0.002), constipation (p = 0.034), diarrhoea (p = 0.021), and financial difficulties (p = 0.039). CONCLUSION: Patients with MDD had reduced quality of life. Fatigue, pain, dyspnoea, insomnia, appetite loss, constipation, diarrhoea, and financial difficulties were prevalent among patients with MDD.

RESUMO

SETTING: Two human immunodeficiency virus (HIV) clinics providing antiretroviral therapy (ART), Mandalay, Myanmar. OBJECTIVE: To assess prevalent TB at enrolment, incident TB during follow-up and associated risk factors in adult people living with HIV (PLHIV) between 2011 and 2017. DESIGN: Cohort study using secondary data. RESULTS: Of 11 777 PLHIV, 2911 (25%) had prevalent TB at or within 6 weeks of enrolment. Independent risk factors for prevalent TB were being male or single/widowed, daily alcohol consumption, CD4 count 200 cells/µl and anaemia. During 6 years follow-up in 8866 PLHIV with no prevalent TB, the rate of new TB was 2.9 per 100 person-years (95%CI 2.6-3.1). Cumulative TB incidence was 9.6%, with 370 (72%) of 517 new TB cases occurring in the first year. Independent risk factors for incident TB were being male and anaemia. Incident TB was highest in the first year of ART, in PLHIV with CD4 counts 200 cells/µl and those not receiving isoniazid preventive therapy (IPT). Incident TB declined with time on ART and rising CD4 counts. CONCLUSION: Prevalent and incident TB were high in PLHIV in the Mandalay clinics. Consideration should be given to earlier TB diagnosis using more sensitive diagnostic tools, effective ART and scaling up IPT.

RESUMO

Assessment of schoolchildren's knowledge, attitudes, and practices towards influenza A (H1N1) is crucial as schools play a major role in spreading the infection. The aims of this study were to determine the level of knowledge, attitudes, and practices on influenza A (H1N1) and the factors associated with practices of preventive behavior.A cross sectional study was conducted from July until December 2010. Two public secondary schools for two districts in Kelantan, Malaysia were randomly selected. Data were collected using a self-administered questionnaire. The questionnaire consisted of five constructs: sociodemographic, risk factors of containing influenza A (H1N1) infection, knowledge, attitudes, and practices. The questionnaire had been te,sted for its construct validity and reliability. General linear regression was applied in the data analysis. A sample of 436 secondary school students were recruited in this study involved Malay students aged 16 years old. The total knowledge, attitudes and practices scores for the overall respondents were 69.4, 82.2, and 73.8%, respectively. The significant influencing factors for the practices of preventive behavior were attended talk on H1N1 and attitudes score.This study suggested that health education is important for promoting the health of adolescents and contributing to the overall health of the public so that they will take precautions against the H1N1 infection.

RESUMO

INTRODUCTION: The aim of this study was to determine whether there was a difference in the pain indicators and effectiveness between venipuncture (VP) and heel prick (HP) for blood glucose monitoring in term neonates (recently, venipuncture was shown superior for the Guthrie test). METHODS: 66 term neonates undergoing blood glucose monitoring underwent VP or HP. Primary outcome measures included the Neonatal Facial Scoring System (NFCS) score, duration of the first cry, total duration of cry and duration of procedure. Secondary outcome measured was the number of skin punctures needed to obtain blood. RESULTS: The NFCS score was not significantly different between the two groups and the duration of the procedure was significantly longer for the VP than the HP group (median 27 s vs. 7 s; p-value is less than 0.001). The differences between the two groups in the duration of the first cry, total duration of cry and number of skin punctures needed to obtain blood were not statistically significant, but these parameters displayed a trend, favouring the HP. CONCLUSION: The HP is still the preferred method of drawing blood in neonates for blood glucose monitoring, as only one drop of blood is required.

RESUMO

This study was conducted to determine the prevalence of Helicobacter pylori (H. pylori) and its associated factors among patients with peptic ulcer disease in Taiping Hospital. Consecutive peptic ulcer disease patients who had undergone esophagogastro-duodenoscopy were included. The H. pylori status was assessed by the rapid urease test. We excluded those who had active bleeding, a perforated peptic ulcer, severe vomiting, a history of gastric surgery, peptic ulcer disease or renal or liver diseases, carcinoma of the stomach, and recent use of antibiotics or proton pump inhibitors. Socio-demography, H. pylori status, medication history and other relevant clinical data were collected from case notes. A total of 416 subjects were selected, 49.7% were positive and 50.3% were negative for H. pylori infection. There were significant associations between H. pylori and age, ethnicity, smoking status and NSAID usage. However, there were no significant relationships between H. pylori status and gender or type of peptic ulcer. Multiple logistic regression showed that other ethnicities than Malays and smokers had a higher risk of H. pylori. Our prevalence rate was low and the identified risk factors were consistent with previous studies. Ethnic differences may be related to genetic and sociocultural behaviors. Quitting smoking may benefit peptic ulcer patients with H. pylori infection.

RESUMO

Non-traumatic Altered States of Consciousness (ASC) are a non-specific consequence of various etiologies, and are normally monitored by Glasgow Coma Scale (GCS). The GCS gives varriable results among untrained emergency medicine personel in developing countries where English is not the first language. An In House Scoring System (IHSS) scale was made by the first author for the purpose of triaging so as to quickly asses patients when seen by medical personel. This IHSS scale was compared to the GCS to determine it's specificity and sensitivity in the accident and emergency department (ED) of Hospital University Sains Malaysia (HUSM). All patients with non-traumatic ASC were selected by purposive sampling according to pre-determined criteria. Patients were evaluated by the two systems, IHSS and GCS, by emergency physicians who were on call. Patient demographics, clinical features, investigations, treatment given and outcomes were collected and followed for a period of 14 days. A total of 221 patients with non-traumatic ASC were studied, 54.3% were males. The mean age of the patients was 56 years old. The mean overall GCS score on presentation to the ED was 10.3. The mean duration of ASC was 11.6 hours. One hundred thirty patients (58.8%) experienced ASC secondary to general or focal cerebral disorders. The mortality rate was 40.3% 2 weeks after the ED visit. Fifty-four point three percent of the patients were awake and considered to have good outcomes while 45.7% of the patients had poor outcomes (comatose or dead) 2 weeks after the ED visit. The mean overall GCS score, verbal and motor subscores as well as the IHSS had significantly decreased (worsened) after treatment in the ED. A poor IHSS scale, hypertension, current smoking, abnormal pupillary reflexes and acidosis were associated with a worse 2-week outcome. The mean age and WBC count was lower and the mean overall GCS score and eye, verbal and motor subscores were higher as well as those having a lower IHSS scale for the good outcome category. Multivariate analysis revealed that smokers and hypertensives were at higher risk for a poor outcome. Higher eye scores on the GCS were associated fewer poor outcomes. There was significant agreement between the IHSS scale and GCS scores in the assessment of non-traumatic ASC. The sensitivity and specificity of the IHSS score versus GCS were 71.9% and 100.0%, respectively.

RESUMO

The aim of this study was to screen and identify the types of thalassemia among blood donors at the Hospital Universiti Sains Malaysia (HUSM). Thalassemia screening was performed by hemoglobin electrophoresis. A total number of 80 blood samples were obtained from donors at the Transfusion Medicine Unit, HUSM. The ethnic origins of the donors were Malays (n=73, 91.3%) and non-Malays (n=7, 8.75%). Males comprised 88.1% of the donors. Thalassemia was detected in 16.25% (n=13) of the blood donors. Of those with thalassemia, 46.2% (6/13) were anemic. Microcytosis and hypochromia were detected in 84.6% (n=l1) and 84.6% (n=l1) of these donors, respectively. The types of thalassemias detected were Hb E, 11.25% (n=9/80) and beta thalassemia trait, 5% (n=4/80). Among the thalassemias detected, the Hb E hemoglobinopathy was comprised of Hb E/ alpha-thalassemia (38.5%: n=5), Hb E /beta-thalassemia (23.1%: n=3), Hb E trait (7.6%: n=1) and beta-thalassemia (30.8%: n=4). In conclusion, screening for thalassemia trait should be included as part of a standard blood testing before blood donation. Further studies are required to look at the effects of donated thalassemic blood.

RESUMO

There is very little data regarding the factors related to intima-media thickness (IMT) of the common carotid artery in normal individuals in those with non-insulin diabetes mellitus and perimenopausal women in Southeast Asian countries. Ultrasound imaging evaluating the carotid artery IMT in those with diabetes and those on hormone replacement therapy (HRT) was performed beginning in August 2000 for a period of nearly two years at the Department of Radiology, Hospital Universiti Sains Malaysia, Kubang Kerian, Kelantan, Malaysia. A total of 153 participants were included. Significant differences between the women on HRT and not on HRT were IMT and systolic blood pressure. When comparing those with non-insulin dependent diabetes mellitus (NIDDM) and normal individuals, the significant differences were IMT, total cholesterol level, systolic blood pressure and diastolic blood pressure. IMT was high in those with NIDDM but not in those on HRT. Both those with NIDDM and those on HRT had associated dyslipidemia and systolic hypertension.

RESUMO

INTRODUCTION: The aim of this study was to identify the prognostic factors that influence the survival of differentiated thyroid cancer patients treated at Hospital Universiti Sains Malaysia (HUSM). METHODS: A total of 178 patients diagnosed with and treated for differentiated thyroid cancer in HUSM between January 1974 and July 2003 were included in this retrospective cohort study. The additional follow-up period was one year after the end of the recruitment phase. The data was collected from the medical records of the patients. RESULTS: The overall five- and ten-year relative survivals of differentiated thyroid cancer patients in HUSM were 90.6 percent (95 percent confidence interval [CI] 84.4-94.4) and 85.3 percent (95 percent CI 76.0-91.2), respectively. The significant prognostic factors for differentiated thyroid cancer were age (hazard ratio [HR] 6.9; 95 percent CI 1.7-28.6), loss of appetite (HR 10.9; 95 percent CI 2.7-43.7), tumour size (HR 3.7; 95 percent CI 1.1-13.8), regional recurrences (HR 3.2; 95 percent CI 1.1-9.8), high-risk stage (HR 19.9; 95 percent CI 4.4-90.4), and treatment (HR 0.2; 95 percent CI: 0.1-0.5). CONCLUSION: The survival rates obtained in this study were slightly lower than other studies but the pattern of survival rates between groups were similar. Prognostic factors identified in this study were similar to those of other studies, suggesting that the experience of HUSM was almost similar with that of other institutions.

RESUMO

The aims of this study were to determine the prevalence, knowledge and factors that influence smoking in Malay primary school children in Tumpat, Kelantan. A cross-sectional study was conducted in February 2004 among primary school children in Tumpat District. Two hundred-twelve children in standard one to six were randomly selected from three rural schools. An interview that included information on history of ever smoking, knowledge related to smoking and health, and potential factors that could influence smoking was done. Twenty-five children had previously smoked, with a prevalence of 11.8% (95%CI=8.0, 17.0) and 8 were current smokers (3.8%, 95%CI=1.2, 6.4). More than half (64.6%) of the children had a good knowledge of smoking. However, only 105 (49.5%) of them knew that passive smokers have a higher risk of developing diseases. Of those who had ever smoked, 12 (36.6%) were influenced by peers and 17 (51.5%) had a self-desire to smoke. The earliest age to start smoking was at 6 years. Factors found to be significantly associated with smoking on multivariate analysis were increasing age (OR=2.8, 95%CI=1.6, 5.1), being boys (OR=5.8, 95%CI=2.0, 16.8), being at second school level (standard 4, 5, 6)(OR=7.8, 95%CI=1.3, 45.3) and having other family members (excluding father) who smoked (OR=2.8, 95%CI=1.2, 6.5). However, having a father who smoked and a good knowledge were not reported as influencing factors.

RESUMO

INTRODUCTION: Computed tomography (CT) perfusion is a new method to diagnose ischaemic stroke especially in developing countries. It identifies the area and is useful to predict the size of final infarction. The aim of this study was to assess cerebral ischaemia with CT perfusion (CTP) among patients with acute ischaemic stroke in Hospital Universiti Sains Malaysia, a tertiary referral centre in a rural setting. METHODS: 42 consecutive unenhanced CT and CTP examinations of the brain in adult patients were evaluated prospectively. Unenhanced CT images were divided into normal, suspicious or frank infarction. CTP images was classified as normal or ischaemic. Subgroup analysis was carried out with a limit of six hours from time of ictus. RESULTS: Out of 42 patients, 20 had frank infarction on unenhanced CT, 15 had suspicious CT studies, while seven were normal. There was no significant association of demographical, clinical and radiological parameters to CTP in the whole group among acute stroke patients without frank infarction. Among the subgroup of patients without frank infarction, there was no significant association between unenhanced CT and CTP in patients who were studied less than six hours after stroke (p-value is 0.063) as well as those after six hours (p-value is 0.317). The prevalence of a normal unenhanced CT and positive CTP for ischaemia was 22.7 percent (95 percent confidence interval 7.8, 45.4). CONCLUSION: CTP may be a useful imaging tool for determining cerebral infarction in a rural-based community population, especially in cases where the unenhanced CT is normal. Thrombolysis is a therapeutic option, even when the history of onset of stroke is unclear.

RESUMO

A total of 31 adult patients with moderate and severe head injury were assessed clinically on admission for Glasgow Coma Scale (GCS) and short test of mental status (STMS) on follow-up and compared to their initial and follow up CT scan. Good predictors were admission GCS, midline shift, volume of subdural haemorrhage in the initial CT scan of the brain as well as the presence of post-traumatic hydrocephalus, gliosis and site of gliosis in the follow-up CT scan. There was no direct correlation between the significant predictors on the first CT scan and the follow-up CT scan of the brain.

RESUMO

Advances in neuroimaging techniques, particularly Magnetic Resonance Imaging (MRI), have proved invaluable in detecting structural brain lesions in patients with epilepsy in developed countries. In Malaysia, a few electroencephalography facilities available in rural district hospitals run by trained physician assistants have Internet connections to a government neurological center in Kuala Lumpur. These facilities are more commonly available than MRI machines, which require radiological expertise and helium replacement, which may problematic in Southeast Asian countries where radiologists are found in mainly big cities or towns. We conducted a cross-sectional study over a two year period begining January 2001 on rural patients, correlating EEG reports and MRI images with a clinical diagnosis of epilepsy to set guidelines for which rural patients need to be referred to a hospital with MRI facilities. The patients referred by different hospitals without neurological services were classified as having generalized, partial or unclassified seizures based on the International Classification of Epileptic Seizures proposed by the International League Against Epilepsy (ILAE). The clinical parameters studied were seizure type, seizure frequency, status epilepticus and duration of seizure. EEG reports were reviewed for localized and generalized abnormalities and epileptiform changes. Statistical analysis was performed using logistic regression and area under the curve. The association between clinical and radiological abnormalities was evaluated for sensitivity and specificity. Twenty-six males and 18 females were evaluated. The mean age was 20.7 +/- 13.3 years. Nineteen (43.2%) had generalized seizures, 22 (50.0%) had partial seizures and 3 (6.8%) presented with unclassified seizures. The EEG was abnormal in 30 patients (20 with generalized abnormalities and 10 localized abnormalities). The MRI was abnormal in 17 patients (38.6%); the abnormalities observed were cerebral atrophy (5), hippocampal sclerosis (4), infarct/gliosis (3), cortical dysgenesis (2) and tumors (2). One patient had an arachnoid cyst in the right occipital region. Of the 17 patients with an abnormal MRI, 14 had an abnormal EEG, this difference was not statistically significant. There was no significant associaton between epileptographic changes and MRI findings (p = 0.078). EEG findings were associated with MRI findings (p = 0.004). The association between an abnormal EEG and an abnormal MRI had a specificity of 82.4%, while epileptogenic changes had a specificity of 64.7% in relation to abnormal MRI findings. This meants that those patients in rural hospitals with abnormal EEGs should be referred to a neurology center for further workup and an MRI to detect causes with an epileptic focus.

RESUMO

INTRODUCTION: Paediatric minor head injuries (MHI) are just as common in both bigger and smaller towns in Malaysia. Urban-based MHI are due more to motor vehicular injuries compared to rural-based MHI which are mainly due to non-motor vehicular injuries. The main objectives of this study were to compare incidence of admitted patients to accident and emergency departments of hospitals in two different settings in Malaysia, namely: Ipoh (urban-based) and Kota Bharu (rural-based); and to correlate to demographical characteristics, types of accident, clinical signs and symptoms, radiological and computed tomography (CT) findings, management; and finally, to determine clinical predictors of intracranial injury in MHI. METHODS: A cross-sectional study of 153 paediatric patients aged 2-18 years who were admitted to the Ipoh Hospital, Perak and 112 patients of the same age group admitted to Hospital Universiti Sains Malaysia, Kelantan were included in this study. The study period was between 1 January 1998 and 31 December 2001. Data collection was done prospectively. Chi-square and independent t-tests were applied to compare characteristics of patients admitted to these two hospitals. Backward stepwise multiple logistic regression was applied to determine clinical predictors of intracranial injury. RESULTS: There were significant differences of age, race, types of accidents, clinical signs and symptoms, Glasgow coma scale (GCS), skull fracture and CT findings between two hospitals. Significant clinical predictors were headache (OR 20.8, 95 percent CI 3.9-25.2, p-value is less than 0.001), unequal pupils (OR 8.4, 95 percent CI 4.3-17.9, p-value is equal to 0.0413) and GCS score of 13 (OR =3.8, 95 percent CI 1.9-6.8, p-value is equal to 0.005). Skull fractures and intracranial injuries were more common in Kota Bharu due to children riding motorcycles without helmets than in Ipoh (p-value is less than 0.001). CONCLUSION: In the rural Malaysian community, both the police and physicians must be alerted to the fact that unhelmeted children riding motorcycles are more likely to sustain morbidity than those in urban areas. More aggressive traffic policing of the village roads should be done by the relevant authorities.

RESUMO

The monitoring of craniospinal compliance is uncommonly used clinically despite it's value. The Spiegelberg compliance monitor calculates intracranial compliance (C = deltaV/deltaP) from a moving average of small ICP perturbations (deltaP) resulting from a sequence of up to 200 pulses of added volume (deltaV = 0.1 ml, total V = 0.2 ml) made into a double lumen intraventricular balloon catheter. The objective of this study was thus to determine the effectiveness of the decompressive craniectomy done on the worst brain site with regard to compliance (Cl), pressure volume index (PVI), jugular oximetry (SjVo2), autoregulation abnormalties, brain tissue oxygen (TiO2) and cerebral blood flow (CBF). This is a prospective cohort study of 17 patients who were enrolled after consent and approval of the ethics committee between the beginning of the year 2001 and end of the year 2002. For pre and post assessment on compliance and PVI, all 12 patients who survived were reported to become normal after decompressive craniectomy. There is no significant association between pre and post craniectomy assessment in jugular oxymetry (p > 0.05), autoregulation (p > 0.05), intracranial brain oxymetry (p = 0.125) and cerebral blood flow (p = 0.375). Compliance and PVI improved dramatically in all alive patients who received decompressive craniectomy. Compliance and PVI monitoring may be crucial in improving the outcome of severe head injured patients after decompressive craniectomy.

RESUMO

Minor head injury in a developing country like Malaysia is managed by primary care physicians and/or medical assistants in district hospitals. These patients are seen initially in their local hospitals, which have at least an X-ray machine for the purpose of screening. This study aimed to guide these physicians to manage these patients at a primary care level. A cross-sectional study was conducted and the study revealed significant predictors of significant computed tomographic (CT) findings. The presence of a Glasgow coma scale (GCS) score of 14 or 13 was associated with the risk of developing significant CT findings compared to patients with a GCS of 15 (p<0.001). Thirty-seven out of 50 patients with GCS of 14 or 13 developed clinically significant brain injury on CT scan. Similarly, the presence of skull fracture was associated with the risk of developing CT abnormalities (p<0.001). Forty-two out of 51 patients with skull fracture developed clinically significant CT findings. Vomiting was associated with developing CT abnormalities (p=0.017). Twenty-seven out of 40 patients with vomiting showed significant CT findings. Soft tissue injury was also found to be associated with developing CT abnormalities (p=0.007). Therefore, we propose reclassifying minor head injury based on the GCS score. Patients with a GCS score of 15 were classified as having mild head injury, while patients with a GCS score of 13 or 14 were at higher risk of developing brain injury and therefore categorized as high risk mild head injury. This group requires emergency CT scan examination, especially when associated with non-motor vehicle accidents, abnormal central nervous system (CNS) examination, craniofacial injuries or skull fractures. They should be referred to a general surgical unit which can treat head injuries or a neurosurgical tertiary centre.
