Three millilitres of plain 0.5% bupivacaine were injected intrathecally at two different spinal interspaces (L2/3 and L4/5) and at two different speeds (15 and 30 sec) in four groups of ten patients. Injection at L2/3 over 15 sec produced a significantly higher mean maximum spread of analgesia (T6.4) when compared to injection at L4-5 over 15 sec (T10.3) (P < 0.05). Over the same interspace L2/3, injection over 15 sec also produced a higher level of spread as compared to the 30 sec group (p < 0.05). At 15 min there was a greater fall in blood pressure in the L2/3 15 sec group when compared to the other groups (p < 0.01). There was a further decrease in the blood pressure in L2/3 15 sec and L4/5 30 sec groups after 30 minutes of blockade (p < 0.01). Therefore close monitoring of cardiovascular parameters must be continued for at least 30 min in spinal anaesthesia with bupivacaine.
Thirty-one healthy women who underwent Caesarean section were studied in a double-blind trial to compare the effectiveness of epidural 0.5% bupivacaine plain, 0.5% bupivacaine plus 100 micrograms fentanyl and 0.5% bupivacaine plus 50 micrograms fentanyl in the prevention of intraoperative pain. There was no difference in the quality of analgesia between the three groups. The incidence of complications was significantly higher in the 0.5% bupivacaine plus 100 micrograms fentanyl group compared with the other two groups.
This was a prospective randomised, controlled, single-blind study done to determine the effect of intrathecal morphine 0.1 mg as compared with intrathecal fentanyl 25 microg in terms of analgesia and duration for postoperative pain relief after Caesarean section. Sixty ASA I or II parturients were randomised into two groups. Group 1 (n=33) received 1.8 ml of 0.5% hyperbaric bupivacaine combined with 0.1 mg morphine while Group 2 (n=27) received 1.8 ml of 0.5% hyperbaric bupivacaine combined with 25 microg fentanyl for spinal anaesthesia. Postoperatively, all patients were provided with patient controlled analgesia (PCA) morphine. Pain was assessed using visual analogue score (VAS) at 6, 12, 18 and 24 hours. Time to first demand of PCA morphine, cumulative PCA morphine requirement and opioid side effects were documented. The VAS for pain and the cumulative PCA morphine requirement were both significantly lower in Group 1 (p < 0.05) during the 24 hours study period. The time to first demand was also significantly longer in Group 1 (p < 0.05). Overall, there were no significant difference between the two groups in side effects, except for a high incidence of nausea and vomiting requiring treatment in Group B in the first six hours. In conclusion the addition of 0.1 mg morphine for spinal anaesthesia provided superior and longer postoperative analgesia after Caesarean section.
A prospective randomized double-blind study was conducted which involved, 60 ASA 1-2, aged 18-65 years patients, who had elective or emergency orthopaedic surgeries of the upper limbs. They were randomly divided into two groups: Group I received 30 mls of 0.5% ropivacaine; and Group II received 0.5% levobupivacaine for infraclavicular brachial plexus block based on the coracoid approach. The onset time required for sensory block of all required dermatomes (C5-T1) and the onset time of motor block were documented. Based on the Visual Analogue Score, pain scores were recorded every 30 minutes during surgery and at the 6th hour. The mean onset time (SD) for sensory block with ropivacaine was 13.5 +/- 2.9 minutes compared to levobupivacaine at 11.1 +/- 2.6 minutes (p = 0.003). The onset time for motor block was 19.0 +/- 2.7 minutes in Group I compared to 17.1 +/- 2.6 minutes (p = 0.013) in Group II. Patients in both groups experienced both mild to moderate pain at the 6th hour. In conclusion, there were statistically significant differences in the onset-time for sensory and motor block. However, there was no statistically significant difference in terms of effectiveness of analgesia at the 6th hour. Although the clinical advantage of levobupivacine is not substantial, its safety profile becomes a major consideration in the choice of local anaesthetic for brachial plexus block where a large volume is required for an effective result.
The detection of Vibrio cholerae 01 from the aquatic environment of Daro and Bintulu in Sarawak was carried out following an outbreak of cholera. Conventional culture methods and detection of ctx gene by polymerase chain reaction technique were carried out on 80 water samples. Only one sample was positive by culture methods while 8 were positive by PCR. DNA finger printing by pulsed-field gel electrophoresis showed that the clinical isolates in Daro and Bintulu were genetically identical while the environmental isolate was closely related. Recovery of Vibrio cholerae by culture method is poor and newer methods of detection should be developed.
One thousand consecutive cases of carcinoma of the uterine cervix treated in the General Hospital Kuala Lumpur between January 1977 to December 1979 were studied. Epidemiological breakdown by race, age, parity, occupation, stage and histology of the disease were obtained. Treatment complications in survivors available for follow-up were analysed. The Chinese had the highest incidence, followed by the Indians and the Malays. Ninety six percent were squamous cell cancers, the remaining were adenocarcinomas. Eighty percent of patients were seen at an advanced stage (Stage IIB-IV). Late radiation complications were mainly proctitis, cystitis and fistula; (5%, 7.2% and 1.4% respectively). These figures are comparable to many centres but the incidence of cystitis is relatively higher. This is believed to be related to irradiation techniques in these cases.
From January to December 1992, 92 babies weighing 1000-1499 gm here to referred as very low birth weight (VLBW) were admitted to NICU (Neonatal Intensive Care Unit), Hospital University Sains Malaysia (HUSM). Sixty babies were inborn giving a VLBW rate of 7.5 per 1000 live births. Incidence of nosocomial sepsis was 32.6% (30/92) of whom 43.3% (13/30) died. Eighty percent (24/30) of the septic babies had blood culture positive for gram negative organisms of which 40% (12/30) were sensitive only to imipenem. Ventilator support within 24 hours of life was required in 41.3% (38/94) babies of whom 42% (16/38) babies developed nosocomial sepsis. Delayed initiation of feeding was significantly associated with nosocomial sepsis. A strict asepsis policy and early feeding of the VLBW infant are essential components of any strategy to prevent of sepsis due to nosocomial infection.
Spinal anaesthesia was performed on 101 patients with a 25-Gauge (0.52 mm) needle. We found a 13.9% overall incidence of postdural puncture headache (PDPH) in an orthopaedic population whose mean age was 33.6 years. This incidence is too high and an alternative technique may be needed.
An analysis of 105 consecutive patients with chronic hepatitis C at the gastroenterology outpatient's clinic in Hospital Kuala Lumpur was performed. The clinical, laboratory and virological data was prospectively recorded in the case notes and comprised of data on patient characteristics, risk factors, clinical features, laboratory features, virology screen and management. Chronic Hepatitis C cases accounted for 2.1% of the total number of cases seen at this clinic during the entire period. There were 78 (74%) males and 27 (26%) females. The ethnic breakdown consisted of Chinese (44.2%), Malays (39.4%), Indians (15.4%) and others (1%). There was higher male preponderance in all the ethnic groups. The main mode of transmission was blood transfusion comprising 51 patients (48.8%). A total of 35.2% of cases underwent treatment, of which a proportion had interferon monotherapy for 6 or 12 months and a subsequent group of naïve patients and non-responders underwent combination therapy with interferon and ribavarin.
This retrospective study was conducted in a state hospital set-up and aimed at identifying the magnitude of shoulder dislocations and their demographic data, characteristics of the injury, mechanism and predisposing factors, and the instituted treatment. Patients with radiographic evidence of shoulder dislocation admitted to the hospital from January 1999 to December 2002 were included. Data were recorded from the case notes. There were 105 shoulder dislocations with male predomination in 77% cases and age ranged between 11 and 90 years (average 30.9 years). The right shoulder was affected in 68% of the cases. The contributing events were fall in 37% of cases, road traffic accident 23%, sports 17% and pathological conditions 13%. Anterior dislocation occurred in 96.2% of the cases. Posterior and inferior dislocations encountered in two patients for each type. Twelve dislocations were associated fracture of the greater tuberosity, two each with humeral neck fracture and cerebral injuries. First time dislocation occurred in 73.6% of the cases. The recurrences ranged between 2 to 6 times (average 3.4 times). Closed manipulative reduction and strapping was the definitive treatment in 92.4% of the cases and the remaining needed surgical reconstruction. Four patients had open reduction and internal fixation of the associated fractures while another four had arthroscopic Bankart's repair. In conclusion, shoulder dislocation represents the most common shoulder problems. It afflicted young adults of reproductive age (21-40 years) and participation in sports was a risk factor in men. Women over 40 years and fall were at risk to develop shoulder dislocation.
Pulmonary disease is sometimes treated empirically as tuberculosis (TB) in the absence of microbial confirmation if the clinical suspicion of active TB is high. In a country of relatively high TB and low HIV burden, we retrospectively studied 107 patients (69.2% male; mean age (SD): 45 (17) years) who received empirical anti-TB treatment for intrapulmonary opacities or pleural effusions suspected of active TB in our hospitals between 1998 and 2002. The diagnosis of definite or probable 'smear-negative' pulmonary TB was made based on treatment outcome at two months with rifampicin, isoniazid, pyrazinamide and ethambutol (or streptomycin). At this end-point, 81 patients (84.4%) had both clinical and radiological improvement (definite cases), 12 (12.5%) had clinical improvement alone and 3 (3.1%) had radiological improvement alone (probable cases). Confirmation of acid-fast bacilli was subsequently obtained in 12 patients (all definite cases) from culture of initial pulmonary specimens. Eleven patients (10.5%) were diagnosed as 'non-TB' based on absence of both clinical and radiological improvement or discovery of another cause for the pulmonary condition at or before this two-month study end-point. In the 'non-TB' group, 2 had carcinoma, 2 had HIV-related pulmonary diseases, 1 had bronchiectasis, while in 6 causes were indeterminate. Six (6.3%) and 3 (27.3%) patients reported adverse effects from anti-TB drugs from the 'TB' and 'non-TB' groups respectively. Our findings suggest that empirical anti-TB treatment is an acceptable practice if clinical suspicion is high in patients coming in our region.
The common investigations done were pure tone audiometry, electronystagmography, X-ray of the internal auditory meatus, CT-scan of the internal auditory meatus and X-ray of the cervical spine. After the examinations and investigations only 52 patients out of the 107 could be given any diagnosis. The most common diagnosis for the vertigo was Meniere's disease.
This study reviews surgery on acoustic neuromas by the second author using retrosigmoid approach from January 2000 to June 2010 in the state of Sarawak. There was a total of 32 patients in this study. The commonest presenting symptom was hearing loss (81.3%), followed by headache and tinnitus (each 37.5%), ataxia (34.4%) and facial numbness (21.9%). Twenty-seven patients (84.4%) had large tumor (≥ 3cm) while 5 patients (15.6%) had medium size tumor (1.5-2.9cm). The mean tumor size was 3.6 cm. Facial nerve outcome was good to moderate in 93.7% (House and Brackmann Grade I-IV). The most common complications were CSF leak with 3 patients(9.4%) and facial numbness with 2 patients(6.3%). All either resolved with treatment or improved. There was no mortality. Excision of acoustic neuromas using retrosigmoid approach could achieve acceptable facial nerve outcome with a low incidence of morbidity without mortality.
The susceptibility gene for hereditary Medullary Thyroid Carcinoma (MTC) is the RET proto-oncogene. The aim of this study was to evaluate the prevalence of common germline RET mutations in exons 10 and 11 among Iranian MTC patients. Fifty-seven non-related MTC patients were examined in this study (Females: Males =1.2:1.0, Mean age = 40.0 +/- 11.5 years) and the existence of mutations was assessed through the PCR-RFLP technique. The only Multiple Endocrine Neoplasia type 2A (MEN2A) patient displayed a C634W mutation in exon 11. Among 53 apparently sporadic MTC patients, one patient showed a C620R mutation in exon 10 and two other patients displayed C624Y mutations in exon 11 of RET proto-oncogene. Neither the only Multiple Endocrine Neoplasia type 2B (MEN2B) patient nor two Familial MTC patients was found to carry germline mutations in exons 10 and 11. This study reports, for the first time, the prevalence of common RET mutations among Iranian, apparently sporadic MTC patients, underlining the critical importance of screening for RET mutations in such patients.
Confinement homes are private institutions that provide full-time care for newborn babies and their respective postpartum mothers up to one month after delivery. An outbreak of fever and diarrhoea amongst newborns occurred in one such confinement home in Penang between the months of September to October 2004. An outbreak investigation was carried out including all babies, their respective mothers and workers in the home to determine the source of the outbreak and to institute control measures. Based on a working case definition of febrile illness with or without diarrhoea, 11 out of the 13 babies in the confinement home met the case definition. One hundred percent had symptoms of fever. 36.4% had symptoms of diarrhea and other respiratory conditions respectively. The attack rate of among babies in the confinement home was 90%. Echovirus 11 was isolated from 3 out of the 11 febrile cases. Echovirus 11 was isolated from the cerebrospinal fluid and stool of another baby at a private hospital that was epidemiologically linked to the first case. In conclusion, the outbreak of febrile illness amongst newborn babies in the affected confinement home was due to echovirus 11. The source was probably health-care associated with efficient transmission within the confinement home. The faecal-oral route was the most likely mode of transmission.
Parotid swellings are uncommon. Over a twelve-year period, 110 cases of parotid swellings were treated at the Department of Plastic Surgery, Hospital Kuala Lumpur, of which 97 cases were histologically proven to be parotid tumours. 75% of these tumours were benign tumours, and 80% of the benign tumours were pleomorphic adenomas. Among the malignant tumours, 6 cases were adenoid cystic carcinoma and 5 were carcinoma ex-pleomorphic adenoma. There were equal number of male to female patients, with an age range of 14 to 83 years. There is a positive correlation between the final histological diagnosis and FNAC results in 74% of cases. Surgical treatment of choice for benign parotid tumours was near-total parotidectomy whilst for malignant tumours was total radical parotidectomy with sural nerve graft.
A study was conducted at the Army Garrison Hospital at Port Dickson in Peninsular Malaysia to determine the attitudes of 110 married men towards family planning. The sample included 80 Malays and 30 Indians who are army personnel attending the hospital either for medical treatment or a check-up. The study instrument was a pre-tested questionnarie administered by 2 male nurses during the November-December 1975 period. 76 of the respondents were between the ages of 20-34 years. 81 of the respondents had been married for a duration of up to 11 years. A breakdown by religion showed that 80 were Muslims, 25 were Hindus, and 5 were Christians, the latter being all Roman Catholics. All of the respondents were able to read and write in at least 1 language, 36 had had schooling varying from standard 1-6, 40 had had schooling varying between Form 1-Form 3, and 34 had had schooling varying from Form 4-to either Malaysian Certificate of Education Level or Higher School Certificate Level. 103 of the respondents approved of family planning, and of these 63 had always felt this way in the past. 6 respondents indicated that they had not thought about family planning in the past. 87 respondents did not approve of the practice of family planning before having the 1st child. Only 7 of 80 Malays in contrast to 16 of 30 Indian respondents -- a significant difference -- approved of family planning before the 1st child. 89 of the 110 respondents had discussed family planning with their wives; 21 respondents had not. 93 respondents disapproved of induced abortion; 17 approved of it. Only 3 of 80 Malay respondents approved induced abortion, but 14 of 30 Indian respondents indicated approval. 98 of the respondents indicated that they were interested in learning more about family planning, and 96 approved of their wife practicing family planning. 56 respondents were practicing family planning, and 20 indicated that they would do so in the future. 6 said they would not practice family planning, and 28 were uncertain as to whether they would practice family planning. It appears that the better educated approve as well as practice family planning more than those with less education.
One thousand one hundred and sixty three patients (male-852, female-311) with ureteric calculi requiring intervention were treated between April 1988 to July 1992. Four hundred and eleven cases were treated by ESWL Monotherapy, 414 by stone manipulation plus ESWL, 301 by retrograde ureteroscopic lithotripsy, 36 by percutaneous antegrade ureteroscopic lithotripsy and 1 case by open ureterolithotomy. There were 25 failures of the initial procedures. Only three cases that failed primary procedures required open surgery. Other complications include minor ureteric mucosal perforation (3%), infection (3%), transient moderate to gross haematuria (20%), loin ache (26.4%), irritative urination (34.4%) and low grade fever (30.1%). Current modalities used in the treatment of ureteric calculi produce good results and there is generally no primary role for any open surgery.
We studied the prevalence of raised serum CA125 in patients with pleural effusions and explored factors affecting its level. Sixty four patients with benign effusions and 36 patients with malignant effusions admitted to the University Malaya Medical Centre from May 2001 to January 2002 were included in the study. There were no significant differences in age, gender and ethnicity of the patients with benign and malignant effusions. There was also no difference in the frequency of the side of pleural effusion between the two groups but compared to benign effusions, a higher proportion of malignant effusions was moderate to large in size (66% versus 39%, p = 0.011). Serum CA125 levels were above 35U/dL in 83.3% and 78.1% of patients with malignant and benign effusions, respectively (p = 0.532). All patients with underlying malignancy and 95.3% of patients with benign effusions had pleural fluid CA125 levels above 35U/dL (p = 0.187). The median levels of CA125 were higher in the pleural fluid than in the serum in all aetiological groups. Higher serum CA125 levels were more likely to be found in patients with moderate to large effusions (p = 0.015), malignant effusions (p = 0.001) and in female patients (0.016). Serum CA125 level showed significant correlation with pleural fluid CA125 level (r = 0.532, p < 0.001) but not with pleural fluid total white blood cell count (r = -0.092, p = 0.362), red blood cell count (r = -0.082, p = 0.417) and lactate dehydrogenase level (r = 0.062, p = 0.541). We conclude that serum CA125 is commonly elevated in patients with benign and malignant pleural effusions.
Spirometry was performed on 1,999 subjects (1,385 males and 614 females) ranging in age from 13 to 69 years and comprising of all the main races in Malaysia. They were divided into 6 age groups. Mean forced vital capacity (FVC) in the males and females was 3.49 +/- 0.02 L and 2.51 +/- 0.02 L respectively. Both FVC and FEV1 correlated negatively with age. Regression analysis on data between the ages of 20 to 69 years revealed an age-related decline in FVC of about 30 ml per year of life in the males and 22 ml per year in the females. Multiple stepwise regression of the data for the prediction of an individual's FVC above the age of 20 years gave an equation for the males: FVC = 0.0407 (height)-0.0296 (age)-2.343 L and for the females: FVC = 0.031 (height)-0.022 (age)-1.64 L. Predicted FVC values derived from equations based on other populations were considerably higher than the observed mean in this study, re-emphasizing the need to be cautious when applying formulae derived from one population to another. Grossly erroneous conclusions may be reached unless predicted equations for lung-function tests for a given population group are derived from studies based upon the same population group.
132 consecutive cases of supracondylar fractures of the humerus admitted between July, 1997 and February, 1999 were included in a prospective study. There were 93 boys and 39 girls. The age ranges from one to 14 years old. The non-dominant arm was more often injured. Ethnic Malay constituted the majority. Accidents mainly occurred at home with a peak between 4 pm and 8 pm. Majority was presented within 24 hours of injury. Type III fracture with distal fragment in extension predominated. Nerve injuries occurred in 9 cases in which median nerve was the most commonly affected. There was only one open fracture and it was complicated by absent radial pulse and median nerve injury.
Inherited anti-thrombin deficiency is an autosomal dominant disorder which is associated with increased risk for venous thromboembolism (VTE). This condition is very rare in Malaysia and there has been no documented report. Thus, the aim of the present study is to investigate the type of an inherited anti-thrombin deficiency mutation in a 25-year-old Malay woman who presented with deep vein thrombosis in her first pregnancy.
DNA was extracted from the patient's blood sample and buccal mucosal swabs from family members. Polymerase chain reaction(PCR) assays were designed to cover all seven exons of the serpin peptidase inhibitor, clade C (antithrombin), member 1 (SERPINC1) gene; and the products were subjected to DNA sequencing. Sequences were referred to NCBI Reference Sequence: NG_012462.1.
A heterozygous substitution mutation at nucleotide position 13267 (CCT->ACT) was identified in the patient and two other family members, giving a possible change of codon 439 (Pro→Thr) also known as anti-thrombin Budapest 5. The genotype was absent in 90 healthy controls.
The study revealed a heterozygous antithrombin Budapest 5 mutation in SERPINC 1 giving rise to a possible anti-thrombin deficiency in a Malay-Malaysian family.
A 3-year-old girl with facial dysmorphic features suggestive of Cornelia de Lange syndrome was seen in the ophthalmology unit for a right leukocoria. The leukocoria was found to be caused by a large retinoblastoma and the right eye was enucleated. Chromosomal analysis revealed partial chromosome 13q deletion involving band 14 which is associated with a high risk of retinoblastoma. This case shows that patient with chromosome 13q deletion syndrome cannot be diagnosed based on dysmorphic features only. Chromosomal analysis is warranted in all infants with facial dysmorphism suggestive of Cornelia de Lange syndrome so that those with chromosome 13q deletion can be referred early for early detection of retinoblastoma.
Sixty-three breath samples were collected from patients who underwent a 14C-urea breath test. Following ingestion of a radiolabelled 14C-labelled urea solution, breath samples containing 14C-labelled carbon dioxide were trapped in a solution containing hyamine hydroxide. Samples were then counted in a liquid scintillation counter. Breath samples were collected at 2, 15, 20, 25 and 30 minutes following ingestion of the urea solution. The presence or absence of Helicobacter pylori (HP) infection was determined on the basis of endoscopic biopsy tests which included culture, histological examination, rapid urease test and a gram stain of a fresh tissue smear. Thirty-two HP positive and 31 HP negative samples were collected. The mean counts at 15, 20, 12 and 30 minutes time points were: 4413, 4458, 4109 and 3795 dpm respectively for the positive samples and 1275, 877, 690 and 565 dpm respectively for the negative samples. Based on a cutoff value (mean of the negative samples + 3 standard deviations) for every time point, HP positive and negative samples could be clearly differentiated giving a sensitivity and specificity of 100%. The 14C-urea breath test is a reliable and convenient diagnostic test for H. pylori.
The aim of this study was to evaluate the in vitro cytotoxicity of biomaterials; Hydroxyapatite (HA), Natural coral (NC) and Polyhydroxybutarate (PHB). Three different materials used in this study; HA (Ca10(PO4)6(OH)2), NC (CaCO3) and PHB (Polymer) were locally produced by the groups of researcher from Universiti Sains Malaysia. The materials were separately extracted in the complete culture medium (100mg/ml) for 72h and introduced to the osteoblast cells CRL-1543. The viability of osteoblast CRL-1543 cultivated with these extraction materials after 72h incubation period was compared to negative control with neutral red assay by using spectrophotometer at 540nm. The results showed the non-cytotoxicity of the materials. After 72h of incubation period, HA showed 123% viable cells, NC was 99.43% and PHB was 176.75%. In this study, cytotoxicity test dealt mainly with the substances that leached out from the biomaterial. The results obtained showed that the materials were not toxic and also promoted cells growth in the sense of biofunctionality.
The concept of Palliative Care is still quite new in Malaysia and there is a need to promote the awareness of its importance for patients with incurable and advanced illnesses, not only to the public but also to the nursing and medical professionals. These patients especially the poor ones very often have no one to turn to; they cannot afford to seek treatment from the private hospitals, they are turned away from acute General Hospitals and are told that there is nothing more to be done because their illnesses are no longer curable, they cannot pay for GPs to come to their homes, and there is difficulty in purchasing opiate drugs for pain relief. This is a retrospective observational study of the palliative care services we try to provide to those few patients referred to us. This study showed that out of the total of 156 patients, majority were Chinese, peak age between 50-59 years, referrals were mainly from the community and the Obstetrics + Gynaecology department, patients were referred rather late, 60% of patients died at home, most common malignancies being those of the breast, colorectal and cervix, common sites of metastases being the lungs, liver, bones, peritoneum and local infiltration, 87% of patients experienced pain, about 40% of patients were not fully aware of both diagnosis and prognosis, common drugs used being opiate analgesics followed by dexamethasone, H2 antagonist, antiemetics and NSAID.
Alpha thalassaemia is wide spread in Malaysia and is a public health problem. This study aimed to describe the carrier frequencies of α‒thalassaemia and its distribution among major ethnic groups in three states of Malaysia.
Educational forums were organised and study was explained to students from three schools. Students were invited to take part in the screening with parent consent. A total of 8420 adolescent students aged 16 years volunteered to participate in the study. Peripheral blood samples were analysed for complete blood counts, haemoglobin quantification and typing, and serum ferritin levels. Genomic DNA was used for screening alpha thalassaemia alleles by PCR based molecular methods.
We identified seven α‒globin gene defects in 341 (4.08%) students: amongst them α(+)‒ and α(0)‒thalassaemias were detected in 232 (2.77%) and 107 (1.28%) students respectively. Genotype ‒α(3.7)/αα was the most prevalent among sub-populations of Malay, indigenous communities of Sahab and Indian, while ‒‒(SEA)/αα deletion is more prevalent in Malaysian Chinese. It is estimated that 63 pregnancies annually are at risk of Hb Bart's hydrops fetalis.
We have demonstrated the prevalence and mutation patterns of α‒thalassaemia in the 16 year olds in three states of Malaysia. High α(0)‒thalassaemia deletions amongst the study subjects place these carriers at an increased risk of conceiving fetuses with HbH disease and Hb Bart's hydrops fetalis should they choose another heterozygous partner. It is therefore highly recommended to institute community screening programmes and provide prospective carriers with genetic counselling to help them make informed choices.
A series of 167 cases of amoebic liver abscess are studied. The importance of a clinical awareness of amoebic liver abscess in many pyrexic conditions of acute abdomen is mentioned. A review of the management is discussed with the light of experience in 167 cases.
A prospective descriptive study of Primary Biliary Cirrhosis at Hospital Kuala Lumpur was undertaken from January 1992 to December 1999. A total of 17 patients were seen with a female to male ratio of 3.25:1. The mean age at presentation was 45.9 years (range: 14 years to 67 years) with a mean follow-up of 33.4 months (range: 3 months to 95 months). Fatigue was the most common clinical symptom at presentation. Alanine transaminase and alkaline phosphatase levels were elevated in 93% of patients at presentation. The antimitochondrial antibody was positive in 87% of patients. Ursodeoxycholic acid therapy resulted in significant symptomatic relief and biochemical improvement in all those who were treated.
Vancomycin-resistant Enterococcus faecium (VREF) in human infections mostly belong to the high-risk, epidemic, clonal complex-17 (CC17) group. Treatment limitation and high conjugation frequency makes it dominant in hospitals worldwide. We investigated positive cultures by Pulse-field gel electrophoresis (PFGE), multi locus sequence typing (MLST). DNA of two strains (A2 and C) appeared to be clonally related by PFGE. Three strains were of ST 18 type (A1, B and C) and strain A2 is of a new ST 596. This ST 18 type strain found in our study is crucial and is believed to be the first in Malaysia.
Cholera has been in existence in Sarawak for many years and since 1873 many major epidemics have occurred. The epidemics usually occur during the dry months of May, June and July and the population affected are those in coastal areas. As in other outbreaks the areas affected were those which had poor environmental sanitation, poor water supply, poor refuse disposal and indiscriminate disposal of faeces. Malays are more affected as in Peninsular Malaysia outbreaks. The classical biotype was common prior to 1961. In later years the El Tor (biotype) has been responsible for most outbreaks.
The tumour marker CA19-9 is a sensitive marker for pancreatic, gastric and hepatobiliary malignancies. High CA 19-9 level indicates unresectable lesions and a poor prognosis. The objective of the study was to determine the significance and implications of elevated CA 19-9 levels in the serum. A one-year retrospective review of all patients who had CA19-9 measured in our Medical Centre was undertaken; 69 patients were found to have CA 19-9 level above the cut-off value (37 U/ml). Thirty-six patients had malignant and the remaining 33 had benign lesions. CA 19-9 was found to be elevated in malignancies of pancreas, colorectum, lung, liver and ovary. Benign conditions associated with elevation of CA 19-9 included disease of the hepatobiliary system, pneumonia, pleural effusion, renal failure and SLE. In two individuals, there was no obvious cause for the elevation of this marker. CA 19-9 levels were significantly lower in benign than in malignant conditions. In conclusion, elevated CA 19-9 may be found in patients with benign as well as malignant disease. Therefore, it is important (1) that elevated levels of CA 19-9 are interpreted in the light of the clinical presentation of the patient and (2) to be aware of the benign conditions that can be associated with increased levels of this marker. With these factors in mind, CA 19-9 can be used to assist in the diagnosis of pancreatic cancer and assessment of resection adequacy post-operatively.
