RESUMEN

INTRODUCTION: Pediculosis capitis infestation is endemic in both developing and developed countries leading to various physical, economical and psychological consequences. Our main objective was to determine the prevalence and predictors of pediculosis capitis among primary school children in Hulu Langat District, Malaysia. METHODS: An analytic cross-sectional study using cluster random sampling method was carried out in Hulu Langat District, Malaysia. Self-administered pretested questionnaires were used to collect the data. Hair and scalp examination was also carried out. Multivariate logistic regression was used to control for potential confounding and determine the predictors. RESULTS: The overall mean age of the 1,336 respondents was 9.3 years. Majority were males (52.8%), Malays (79.5%) and 81.3% of the fathers had secondary or tertiary education as compared to 77.3% for the mothers. The overall prevalence of pediculosis capitis was 15.3%. The prevalence of pediculosis was significantly higher among females (28.4%) than males (3.7%, p=0.001). Multivariate logistic regression analysis showed that age 10 years or more (Odds Ratio (OR) = 2.34, 95% Confidence Interval (CI) = 1.673 to 3.272), female gender (OR = 10.26, 95% CI = 6.620 to 15.903), history of contact with an infested person (OR = 2.11, 95% CI = 1.506 to 2.960), Indian compared to Chinese (OR = 3.55, 95% CI = 1.282 to 9.860), Malay to Chinese (OR = 2.59, 95% CI = .994 to 6.774) were associated with pediculosis capitis. CONCLUSIONS: Prevalence of pediculosis capitis among children aged 7 - 12 years in Hulu Langat District was high. There is a need for screening and treatment of pediculosis capitis in primary schools.

RESUMEN

Identification of pregnant women infected with Chlamydia trachomatis is essential to allow early antibiotic treatment in order to prevent adverse pregnancy outcomes. In this study, two nucleic acid amplification tests (NAAT) namely nested PCR (BioSewoom, Korea) and Amplicor CT/NG (Roche Diagnostic, USA) were evaluated in terms of sensitivity and specificity for the detection of C. trachomatis DNA in pregnant women with preterm complications. A cross-sectional study was carried out in two public hospitals in Southern Selangor, Malaysia. Endocervical swabs obtained were subjected to DNA amplification using nested PCR (BioSewoom, Korea) and Amplicor CT/NG (Roche Diagnostic, USA). A total of 83 endocervical swabs obtained from pregnant women of less than 37 weeks gestation and presented with preterm complications were subjected to chlamydial DNA detection using both assays. The study shows that Amplicor CT/NG assay is more effective in the detection of C. trachomatis DNA from endocervical swabs compared to Biosewoom nested PCR kit. Agreement between the two assays were poor (kappa=0.094) with nested PCR showing a low sensitivity of 10.81% and a 97.83% specificity when compared to Amplicor CT/NG. The results obtained indicated that BioSewoom nested PCR was less sensitive than Amplicor CT/ NG for detecting C. trachomatis in endocervical specimens and that another more reliable test is required for confirmatory result.

RESUMEN

Low birth weight is a key determinant in the risk of morbidity and mortality in the neonatal period and during childhood. This unmatched case-control study in Hamadan, Islamic Republic of Iran, compared the characteristics of mothers of low- and normal-birth-weight infants. Maternal sociodemographic data, pregnancy history, anthropometric data and cord plasma zinc level were collected from 134 mothers of low-birth-weight infants and 134 mothers of normal infants at the time of delivery. Significant differences in maternal characteristics namely gravida, parity, body mass index, maternal weight gain during pregnancy and plasma cord blood zinc were found between low- and normal-birth-weight infants. There were no significant differences in maternal age, maternal education, maternal occupation, family income, previous abortion, previous preterm labour, birth Iinterval, type of clinic and place of residence between the 2 groups.

RESUMEN

INTRODUCTION: The aim of this study was to investigate the knowledge, attitudes and behaviour of university students regarding acquired immunodeficiency syndrome (AIDS) and the human immunodeficiency virus (HIV). METHODS: A randomised controlled trial of 530 university students was done using peer-adult facilitators. Participants completed a questionnaire before and after the intervention, which was a four-hour group session. A prevention programme was developed by local experts, health educators and peer facilitators. The peer-adult-led programme was designed to provide a conceptual model of HIV risk reduction through information, motivational and behavioural skills, a harm reduction module and health promotion theme. RESULTS: The main outcome measured was the level of knowledge, attitudes and behaviour scores. The results suggest that relative to the control group, participants in the intervention group had higher levels of knowledge (30.37 vs. 25.40; p-value is 0.001) and a better attitude (12.27 vs. 10.84; p-value is 0.001). However, there was no difference in the behavioural score (9.47 vs. 9.41; p-value is 0.530). The correlation between the level of knowledge and age and the level of education was found in the intervention group, but not in the control group (p-value is 0.01). Attitude and gender were found to be correlated in the intervention group only (p-value is 0.01). CONCLUSION: Our programme was successful in increasing knowledge and improving attitudes towards AIDS and HIV. However, it did not improve risk-taking behaviour. Peer-adult-led educational programmes for youth using various interactional activities, such as small group discussions, poster activity and empathy exercises, can be successful in changing the prevailing youth perceptions of AIDS and HIV.

RESUMEN

Shifts in lifestyles and eating patterns have led to an increasing prevalence of chronic non-communicable diseases in the adult population in Mongolia. This article reports the prevalence of obesity, abdominal obesity and body fat among 408 Mongolian adults aged 25 years and above. The subjects included 61.2% from urban areas and 38.8% from rural areas, reflective of the 60: 40 urban rural ratio in the general population. Anthropometric measurements were taken according to standard methods. Classification of overweight/obesity was based on body mass index of WHO while abdominal obesity was based on WPRO for Asians. Men made up 47.8% (200) and women 52.2% (218) of the sample. The mean age of the subjects was 46.7±12.7 years. About one-third (32.8%) of the subjects were overweight and 10.5% obese. A higher proportion of women (13.3%) than men were obese (7.5%). The age groups of 35-54 years in men and 55-64 years in women showed the highest prevalence of overweight. Prevalence of abdominal obesity was found in 46.5% of the men and in 65.1% of the women. Women aged 55-64 years had the highest proportion (78.4%) of abdominal obesity. In terms of body fat, 20.0 % and 51.5% of the men had high and very high levels of body fat respectively, while among the women, 15.1% and 55.5% respectively had high and very high levels of body fat. Mongolian adults face serious risk of cardiovascular diseases and other aspects of ill-health brought about by obesity. Prevention and control of obesity should be targeted as an urgent public health agenda in Mongolia.

RESUMEN

In April 2004, an outbreak of acute diarrheal illness occurred among the Orang Asli (aborigine) in the Cameron Highlands, Pahang State, Peninsular Malaysia, where rotavirus was later implicated as the cause. In the course of the epidemic investigation, stool samples were collected and examined for infectious agents including parasites. Soil transmitted helminthes (STH), namely Ascaris lumbricoides (25.7%), Trichuris trichiura (31.1%) and hookworm (8.1%), and intestinal protozoa, which included Giardia lamblia (17.6%), Entamoeba histolytica/E. dispar (9.4%), Blastocystis hominis (8.1%) and Cryptosporidium parvum (2.7%), were detected. Forty-four (59.5%) were infected with at least one parasite, 24 (32.4%), 12 (16.2%) and 8 (10.8%) had single, double and triple parasitic infections, respectively. STH were prevalent with infections occurring as early as in infancy. Giardia lamblia, though the most commonly found parasite in samples from symptomatic subjects, was within the normally reported rate of giardiasis among the various communities in Malaysia, and was an unlikely cause of the outbreak. However, heavy pre-existing parasitic infections could have contributed to the severity of the rotavirus diarrheal outbreak.

RESUMEN

From July through December 1997, 11 previously healthy children in Peninsular Malaysia succumbed to an illness clinically characterised by an acute severe refractory left-ventricular failure, following a brief prodromal illness, in the midst of an outbreak of hand, foot and mouth disease (HFMD), similar to the reported experience in Sarawak and Taiwan. Retrospective reviews of the clinical features and results of laboratory, pathological and virological investigations of cases were conducted. The median age of the 11 case-patients was 31 months (range, 13 to 49 months); 6 were males. A brief prodromal illness of 3 days (range, 2 to 5 days) was characterised by fever (axillary temperature > 38 degrees C) (100%), oral ulcers (72%), extremity rashes (45%) and significant vomiting (55%). Upon hospitalisation, 7 of 11 case-patients had features suggestive of cardiogenic shock, while 4 of 11 case-patients developed shock during hospitalisation as evidenced by marked sustained tachycardia (heart rate > or = 180 beats per minute), poor peripheral pulses and peripheral perfusion, mottled extremities, pulmonary oedema (haemorrhagic pulmonary secretions in 8 of 11 cases during tracheal intubation, often precipitated by conservative crystalloid boluses, and radiographic evidence of acute pulmonary oedema in 5 of 7 cases) and markedly impaired left ventricular function on echocardiographic examination (7 of 7 cases). Three of 4 case-patients had aseptic meningitis while one case-patient also had an acute flaccid paraparesis. Despite supportive therapy, death occurred within a median of 13.4 hours following hospitalization. Post-mortem findings (all 8 specimens examined) consistently demonstrated brain-stem encephalitis with foci of neuronal necrosis and micro-abscesses. None of the 11 specimens examined revealed histological evidence of myocarditis. Enterovirus 71 (EV71) was detected in 10 of 11 case-patients, many (7) from various sterile tissue sites (5 from central nervous tissues). No other viruses were isolated or identified. Clinical features and pathological studies closely paralleled the reported experience in Sarawak and Taiwan. The uniform necropsy findings of necrotizing brain-stem encephalitis coupled with essentially normal myocardial histology, in concert with the concurrent and consistent detection of EV71 points to a primary EV71 encephalitis; as yet unclear neurogenic mechanisms may account for the cardiovascular manifestations.

RESUMEN

BACKGROUND: An outbreak of encephalitis primarily affecting pig farmers occurred during 1998-1999 in Malaysia and was linked to a new paramyxovirus, Nipah virus, which infected pigs, humans, dogs, and cats. Because five abattoir workers were also affected, a survey was conducted to assess the risk of Nipah infection among abattoir workers. METHODS: Workers from all 143 registered abattoirs in 11 of 13 states in Malaysia were invited to participate in this cross-sectional study. Participants were interviewed to ascertain information on illness and activities performed at the abattoir. A serum sample was obtained to test for Nipah virus antibody. RESULTS: Seven (1.6 %) of 435 abattoir workers who slaughtered pigs versus zero (0%) of 233 workers who slaughtered ruminants showed antibody to Nipah virus (P = 0.05). All antibody-positive workers were from abattoirs in the three states that reported outbreak cases among pig farmers. Workers in these three states were more likely than those in other states to have Nipah antibody (7/144 [4.86%] versus 0/291 [0%], P < 0.001) and report symptoms suggestive of Nipah disease in pigs admitted to the abattoirs (P = 0.001). CONCLUSIONS: Nipah infection was not widespread among abattoir workers in Malaysia and was linked to exposure to pigs. Since it may be difficult to identify Nipah-infected pigs capable of transmitting virus by clinical symptoms, using personal protective equipment, conducting surveillance for Nipah infection on pig farms which supply abattoirs, and avoiding handling and processing of potentially infected pigs are presently the best strategies to prevent transmission of Nipah virus in abattoirs.

RESUMEN

During 1998-1999, an outbreak of Nipah virus encephalitis occurred in Malaysia. To assess the possibility of nosocomial transmission, 338 health care workers (HCWs) exposed and 288 HCWs unexposed to outbreak-related patients were surveyed, and their serum samples were tested for anti-Nipah virus antibody. Needlestick injuries were reported by 12 (3%) HCWs, mucosal surface exposure to body fluids by 39 (11%), and skin exposure to body fluids by 89 (25%). No encephalitis occurred in either group. Three exposed and no unexposed HCWs tested positive by EIA for IgG antibodies. It is likely that these 3 were false positives; no IgM response occurred, and the serum samples were negative for anti-Nipah virus neutralizing antibodies. The risk of nosocomial transmission of Nipah virus appears to be low; however, given the high case-fatality rate and the presence of virus in respiratory secretions and urine of some patients, standard and droplet infection-control practices should be maintained with these patients.

RESUMEN

A hospital-based case-control study of viral encephalitis was carried out at Port Dickson Hospital, in the state of Negeri Sembilan, Malaysia. Between March and May 1999, 69 clinically diagnosed viral encephalitis cases and 31 controls were interviewed. Job histories on pig farming activities were assessed by a group of epidemiologists and veterinary surgeons. Results show that among clinical cases of viral encephalitis, 52 (75.4%) cases were diagnosed to have Nipah virus infection based on positive serology for antibodies to the cross-reacting Hendra virus antigen. The Nipah virus encephalitis was significantly associated with a history of working in pig farms (p < 0.001, OR = 196.0, 95% CI = 20.4-4741.6), history of contact with animals (p < 0.001, OR = 38.3, 95% CI = 8.2-209.0) and with history of direct contact with pigs (p = 0.002, OR = 34.4, 95% CI = 2.6-1,024.4). The Nipah virus infection was also significantly associated with history of feeding/cleaning pigs (p < 0.001, OR = 102, 95% CI = 11.9-2,271.5). These results provide evidence that involvement in pig farming activities is significantly associated with the risk of getting Nipah virus infection. They are potential risk factors for Nipah virus transmission in the major pig-producing area of Bukit Pelandok, Port Dickson Negeri Sembilan.

RESUMEN

Between September 1998 and May 1999, 265 cases of encephalitis were reported from among those involved in pig rearing. A few cases were also reported among abattoir workers. This raised questions of the risk of transmission among those who handled raw pork. A serosurvey was conducted among pork sellers in Seremban town, which is about 20 km from one of the pig rearing areas which had reported cases of encephalitis. It was found that out of the 28 pork sellers tested, only one tested positive for Nipah virus antibodies and that this pork seller also worked in an abattoir in the same district, removing the urinary bladders from slaughtered pigs. Based on these findings, it was concluded that the risk of transmission of the virus from handling raw pork appeared to be low.

RESUMEN

BACKGROUND: During 1990-1992, 282 Chinese residents of Selangor and the Federal Territory, Malaysia with histologically confirmed nasopharyngeal carcinoma (NPC) were interviewed about occupational history, diet, alcohol consumption, and tobacco use, as were an equal number of Malaysian Chinese population controls, pair-matched to cases by age and sex. METHODS: Exposures to 20 kinds of workplace substances, solar and industrial heat, and cigarette smoke, were analysed by univariate and multivariate methods. RESULTS: Nasopharyngeal carcinoma was associated with occupational exposures to construction, metal and wood dusts; motor fuel and oil; paints and varnishes; certain other chemicals; industrial heat; solar heat from outdoor occupations; certain smokes; cigarette smoking; and childhood exposure to parental smoking. After adjustment for risk from diet and cigarette smoke, only wood dust (OR = 2.36; 95% CI : 1.33- 4.19), and industrial heat (OR = 2.21; 95% CI : 1.12-4.33) remained clearly associated. Wood dust remained statistically significant after further adjustment for social class. No significant crude or adjusted association was found between NPC and formaldehyde (adjusted OR = 0.71; 95% CI : 0.34-1.43). CONCLUSIONS: This study supports previous findings that some occupational inhalants are risk factors for NPC. The statistical effect of wood dust remained substantial after adjustment for diet, cigarette smoke, and social class. Intense industrial heat emerged as a previously unreported risk factor, statistically significant even after adjustment for diet and cigarette smoke. No association was found between NPC and formaldehyde.

RESUMEN

An observational study was carried out in the Kuala Lumpur Maternity Hospital to determine the risk factors associated with feed intolerance in very low birthweight (VLBW, <1501 g) infants given intermittent 3-hourly enteral feeds within 72h after birth. Feed intolerance developed in 85 (64.4 per cent) of 132 infants. Logistic regression analysis showed that the only significant risk factor associated with feed intolerance was the age when the first feed was commenced. For each hour delay in the age of the infants when the first feed was given, the adjusted odds ratios of feed intolerance was 1.03 (95 per cent confidence intervals: 1.01-1.05; p = 0.01). Other factors (modes of delivery, Apgar score at 1 min, sex, ethnicity, history of resuscitation at birth, birthweight, gestation, multiple pregnancy, perinatal asphyxia, types of milk, hypothermia before first feed, hypotension before first feed, respiratory distress syndrome, patent ductus arteriosus, septicaemia, theophylline therapy, indomethacin therapy, ventilatory support, continuous positive airway pressure, umbilical catheterization, and surfactant therapy) were not significantly associated with feed intolerance. Our study suggests that to promote tolerance of enteral feeds in VLBW infants, intermittent orogastric feeds should be commenced as soon as possible during the first 72 h of life.

RESUMEN

From April through June 1997, 29 previously healthy children aged <6 years (median, 1.5 years) in Sarawak, Malaysia, died of rapidly progressive cardiorespiratory failure during an outbreak of hand, foot, and mouth disease caused primarily by enterovirus 71 (EV71). The case children were hospitalized after a short illness (median duration, 2 days) that usually included fever (in 100% of case children), oral ulcers (66%), and extremity rashes (62%). The illness rapidly progressed to include seizures (28%), flaccid limb weakness (17%), or cardiopulmonary symptoms (of 24 children, 17 had chest radiographs showing pulmonary edema, and 24 had echocardiograms showing left ventricular dysfunction), resulting in cardiopulmonary arrest soon after hospitalization (median time, 9 h). Cardiac tissue from 10 patients showed normal myocardium, but central nervous system tissue from 5 patients showed inflammatory changes. Brain-stem specimens from 2 patients were available, and both specimens showed extensive neuronal degeneration, inflammation, and necrosis, suggesting that a central nervous system infection was responsible for the disease, with the cardiopulmonary dysfunction being neurogenic in origin. EV71 and possibly an adenovirus, other enteroviruses, or unknown cofactors are likely responsible for this rapidly fatal disease.

RESUMEN

OBJECTIVES: To identify the types of early cranial ultrasound changes that were significant predictors of adverse outcome during the first year of life in asphyxiated term infants. METHODOLOGY: This was a prospective cohort study. Shortly after birth, cranial ultrasonography was carried out via the anterior fontanelles of 70 normal control infants and 104 asphyxiated infants with a history of fetal distress and Apgar scores of less than 6 at 1 and 5 min of life, or requiring endotracheal intubation and manual intermittent positive pressure ventilation for at least 5 min after birth. Neurodevelopmental assessment was carried out on the survivors at 1 year of age. RESULTS: Abnormal cranial ultrasound changes were detected in a significantly higher proportion (79.8%, or n = 83) of asphyxiated infants than controls (39.5%, or n = 30) (P < 0.0001). However, logistic regression analysis showed that only three factors were significantly associated with adverse outcome at 1 year of life among the asphyxiated infants. These were: (i) decreasing birthweight (for every additional gram of increase in birthweight, adjusted odds ratio (OR) = 0.999, 95% confidence interval (CI) 0.998, 1.000; P = 0.047); (ii) a history of receiving ventilatory support during the neonatal period (adjusted OR = 8.3; 95%CI 2.4, 28.9; P = 0.0009); and (iii) hypoxic-ischaemic encephalopathy stage 2 or 3 (adjusted OR = 5.8; 95%CI 1.8, 18.6; P = 0.003). None of the early cranial ultrasound changes was a significant predictor. CONCLUSIONS: Early cranial ultrasound findings, although common in asphyxiated infants, were not significant predictors of adverse outcome during the first year of life in asphyxiated term infants.

RESUMEN

A case-control study was carried out on 152 extremely low birthweight (ELBW, < 1000 g) infants born consecutively in a large Malaysian maternity hospital during a 21-month period to determine the significant predictors associated with survival at discharge. Forty-nine (32.2 per cent) of these infants survived and 103 (67.8 per cent) died. The survivors weighed significantly heavier (mean = 888 g, SD = 99) than infants who died (mean = 763 g, SD = 131; p < 0.0001). They were also of higher gestational age (mean = 28.7 weeks, SD = 2.2) than those who died (mean = 26.7 weeks, SD = 2.5; p < 0.0001). Logistic regression analysis showed that, after controlling for various confounders, only three factors were significantly associated with the survival of these infants. These were: (1) increasing birthweight of the infants (with every gram increase in birthweight, adjusted odds ratio of survival was: 1.009; 95 per cent CI 1.004, 1.015; p = 0.0006); (2) given nasal continuous positive airway pressure for treatment of respiratory distress syndrome (adjusted odds ratio of survival: 4.2; 95 per cent CI 1.2, 14.0; p = 0.02); and (3) given expressed breastmilk (adjusted odds ratio of survival: 57.5; 95 per cent CI: 7, 474; p = 0.0002). Maternal illness, intrapartum problems, ethnicity, gestational age, use of antenatal steroid, modes of delivery, Apgar scores, congenital anomalies, respiratory distress syndrome, persistent ductus arteriosus, septicemia, necrotising enterocolitis, chronic lung disease, oxygen therapy, intermittent positive pressure ventilation, surfactant therapy, and blood transfusion were not significant factors associated with increased survival.

RESUMEN

AIM OF STUDY: With a five-year survival rate of 20% in 1970 and 40-45% in 1990, and highest incidence and mortality in early and middle adult years, nasopharyngeal carcinoma (NPC) may have a severe social impact on families and households. The aim of this study was to measure the social impact of NPC in the Chinese population of Selangor, Malaysia. METHOD: Cases were pooled from three epidemiological case-control studies conducted in 1973-74, 1980, and 1990-92 for a total of 442. They lived in households with a grand total of 2,598 persons. Interviewers collected data on household composition: number of residents; each resident's age, sex, occupation, and relationship to the head of the household; and position of the NPC case in the household. RESULTS: Ninety-four percent of cases supported 93% of household members in some way. Most cases were employed as income earners or homemakers and 80% had a key role as head of household and/or parent of dependent children. CONCLUSION: The illness and death caused by NPC had a major social impact on immediate families and on extended family and non-kin households as well.

RESUMEN

OBJECTIVE: To determine the risk factors associated with umbilical vascular catheter-associated thrombosis. METHODS: All consecutive inborn infants with umbilical arterial (UAC) and/or umbilical venous catheters (UVC) inserted for more than 6 h duration were included in the study. Each infant was screened for thrombosis in the abdominal aorta and inferior vena cava by 2-D abdominal ultrasonography within 48-72 h of insertion of umbilical vascular catheters. Subsequent serial scanning was performed at intervals of every 5-7 days, and within 48 h after removal of catheters. RESULTS: Upon removal of umbilical catheters, abdominal aortic thrombi were detected in 32/99 (32.3%) infants with UAC. Small thrombi were detected in the inferior vena cava of 2/49 (4.1%) infants with UVC (one of whom had both UAC and UVC). When compared with those who received only UVC (n = 18), infants who received either UAC alone (n = 68) or both UAC and UVC (n = 31) had significantly higher risk of developing thrombosis (odds ratio (OR): 7.6, 95% confidence interval (CI): 1.1, 325.5)). Logistic regression analysis of various potential risk factors showed that the only significant risk factor associated with the development of abdominal aortic thrombosis following insertion of UAC was longer duration of UAC in situ (for every additional day of UAC in situ, adjusted OR of developing thrombosis was: 1.2, 95% CI: 1.1, 1.3; P = 0.002). CONCLUSION: Umbilical arterial catheter-associated thrombosis was common. Umbilical arterial catheter should be removed as soon as possible when not needed. Upon removal of UAC, all infants should be screened for abdominal aortic thrombus by 2-D ultrasonography.

RESUMEN

OBJECTIVES: To compare the neurobehavioural outcome of children aged 6-12 years with severe closed head injury [sCHI] (coma > 24 h), mild-to-moderate head injury [mCHI] (coma < 6 h) and orthopaedic controls. METHODS: Twenty-nine children in each group, matched for age, sex and ethnicity, were assessed using the Glasgow outcome Scale (GOS), Weschler Intelligence Scale for Children (WISC-III), Movement Assessment Battery for Children (Movement ABC), Wide Range Assessment of Learning and Memory (WRAML) and a standardised neurological examination 6 months post-injury. Parental reporting of pre- and post-injury behaviour was documented using the Child Behaviour Checklist (CBCL). RESULTS: Seven (24.1%) children with sCHI and three (10.3%) orthopaedic controls had residual motor deficits. Three (10.3%) children with sCHI and none in the other groups faced problems with independent ambulation. Twenty-seven (93.1%) of those with sCHI and all children in the other groups had GOS scores of good recovery or moderate disability. Twenty-two (81.5%) sCHI, five (18.5%) mCHI and one (3.7%) orthopaedic control reported a deterioration in school performance. MANOVAS identified a significant injury group effect for performance skills (P = 0.007), verbal skills (P = 0.002), memory and learning (P = 0.001) and motor skills (P = 0.001). Repeated measures ANOVA for pre- and post-injury CBCL scores showed significant differences related to somatic complaints (P = 0.004), problems of socialising (P = 0.003), delinquency (P = 0.004), aggressiveness (P = 0.010), thought (P < 0.001) and attention (P < 0.001). Post-hoc univariate analysis showed the significant differences were between that of the sCHI children and the other two groups. CONCLUSION: Although most sCHI children seemed to have made good physical recovery, there were cognitive, motor, memory and learning difficulties and behavioural problems concomitant with a deterioration in school performance compared with those with lesser or no head injury. This highlights the need for better integrated rehabilitation services to enable a gradual return into mainstream school.
