    A proportion of patients with acute viral fever with thrombocytopaenia does not necessary have dengue infection. Managing them indiscriminately as dengue infection may not be appropriate. The prevalence of this problem is not exactly known. The objective of this study is to determine the prevalence of acute non-dengue febrile thrombocytopaenia among adult patients presenting with acute non-specific febrile illness in an outpatient setting. This was a clinic-based cross sectional study. Consecutive patients presenting with non-specific febrile illness of less than two weeks were selected from the Primary Care Centre of Hospital Universiti Kebangsaan Malaysia (HUKM) and the Batu 9 Cheras Health Clinic. Full blood count was done on the day of visit and dengue serology was done on day five of illness for all patients enrolled. Seventy three patients participated in this study from May to November 2003. Among the patients, 35 (47.9%) were noted to have thrombocytopaenia. Fourteen (40%) patients with thrombocytopaenia were serologically negative. The prevalence of non-dengue febrile thrombocytopaenia was 19.2%. A significant number of patients with acute non-specific febrile illness with thrombocytopaenia were negative for dengue serology. These patients should be differentiated from those with acute febrile thrombocytopaenia, as they might differ in their natural history from those with dengue infection, and hence require different management strategies.

    Fragile X syndrome is a result of an unstable expansion of (CGG)n trinucleotide sequences in the FMR-1 (Fragile X Mental Retardation 1) gene site at Xq27. In a normal person, n ranges from 6 to 40 repeats with an average of 30 repeats, whereas in a mutated FMR1 gene the sequence is repeated several times over (stuttering gene). Full mutation occurs when n equals 200 repeats or more. Where n equals 50 to 200 repeats, it is a premutation. Fragile X occurs when the FMR-1 gene is unable to make normal amounts of usable Fragile X Mental Retardation Protein, or FMRP. The amount of FMRP in the body is one factor that determines the severity of the Fragile X syndrome. A person with nearly normal levels of FMRP usually has mild or no symptoms, while a person with very little or no normal FMRP has more severe symptoms. The mechanism for the role of the FMRP gene is still being researched upon. However, it has been observed that large numbers of repeats (more than 200) inactivates the gene through a process of methylation and when the gene is inactivated, the cell may make little or none of the needed FMRP. Inheritance is X-linked with reduced penetrance and the frequency of occurrence goes up through generations. The phenotypic manifestations of fragile-X syndrome vary and are largely dependent on the size of the mutation or premutation. The identification of the fragile site on G banded metaphases is a time consuming and delicate process requiring experience and skill, however, molecular diagnosis using DNA analysis and Southern blotting, even though expensive, is more specific in determining the presence or absence of the gene. This study was aimed to establish a rapid polymerase chain reaction (PCR) based - touch down PCR, as a screening method for fragile X syndrome. A total of six cases were analysed. Of these, one was a known case of Fragile X (T1) diagnosed by conventional cytogenetics, two were from the latter’s family members namely, his mother (T2) and father (T3), and the other two (T4 and T5) were randomly selected from patients presenting with dysmorphic features and delayed development respectively. One normal control (TC) was included. Cytogenetic analyses for detection of the fragile site was carried out in all cases. Two culture systems were used, namely the synchronised lymphocyte culture and the folate - thymidine deficient culture. Stained metaphases from the fragile X cultures were screened for the presence of the fragile site on the X chromosome. G-banded karyotyping was done using an image analyser to exclude presence of chromosomal abnormalities. DNA was extracted from these samples and amplified by touch-down PCR. Cytogenetic analysis revealed a folate-sensitive fragile site in the affected male, but none in the other five samples. G-banded karyotyping exhibited no additional chromosomal abnormalities. All extracted DNA samples were successfully amplified. Five of the samples showed presence of the product at the expected band at 552bp, excluding the presence of an expansion of CGG segment of the FMR-1 gene. The absence of a band in an affected individual, suggested a fully mutated allele of FRAXA (Folate Sensitive Fragile Site at Xq28). We succeeded in establishing a slightly modified touch-down PCR analysis. Our study indicates that PCR testing offers a rapid and specific method for screening of normal allele and full mutation of the fragile X gene. We suggest this technique to be applied as a complementary tool for cytogenetic analysis to detect the FRAXA gene.

    Fine needle aspiration cytology under radiologic guidance for diagnosis of renal cell carcinoma is well established and is increasingly utilized. This is because renal cell carcinoma displays fairly characteristic cellular features permitting correct cytologic identification. We present a case of a 66-year-old man who had advanced renal cell carcinoma with spread to aortic and cervical lymph nodes, lungs and liver. Fine needle aspiration cytology of the para-aortic mass showed tight clusters of malignant cells with abundant and vacuolated cytoplasm consistent with renal cell carcinoma. Histology of the left cervical lymph nodes together with immunohistochemistry findings were consistent with the cytologic diagnosis of metastatic renal cell carcinoma. The patient succumb to his illness three years after the diagnosis was made.

     Myelofibrosis is a chronic myeloproliferative disorder characterised by splenomegaly, leukoerythroblastic anaemia, tear-drop poikilocytosis and marrow fibrosis. Splenectomy is indicated for patients requiring frequent transfusions or massive splenomegaly causing distressing symptoms and severe thrombocytopenia secondary to hypersplenism.A 56 year-old lady diagnosed to have primary myelofibrosis in year 2000 was referred to HUKM for further management of her increasing requirement of blood transfusion and massive splenomegaly. She has had two episodes of acute cholecytitis. Investigations done in our hospital showed that her hemoglobin level was 6.4g/dl, white cell count of 23.4x109/l, platelet count 163x109/l and peripheral blood showing leukoerythroblastic picture and tear-drop poikilocytosis. Leukocyte alkaline phosphatase score (NAP) was 184/100 neutrophils. Ultrasound of the abdomen showed massive splenomegaly with multiple gall stones. In view of the frequent transfusion requirements and symptomatic massive splenomegaly, splenectomy and cholecystectomy was performed. A review of her peripheral blood picture, post-splenectomy, showed marked reduction of the tear-drop poikilocytosis and leukoerythroblastosis. We believe that the spleen plays an important role in their formation, but the exact mechanism remains unclear.

    Villoglandular papillary adenocarcinoma was first described by Young and Scully in 1989 as a distinct entity with the histological features of exophytic growth proliferation, villous and papillary architecture and mild to moderate nuclear atypia. We report one case of villoglandular papillary adenocarcinoma (VGPA) of the uterine cervix with lymph node metastasis and reviewed the clinicopathological features of six other cases reported in the literature. Our patient is the seventh similar reported cases. They ranged in age from 29 to 54 (mean, 41) years. Five had lymphovascular invasion. All except our patient were treated with radical hysterectomy and radiotherapy. She was followed-up for 7 months and unfortunately died due to chest infection.

    In this report we demonstrate the role of fluorescence in situ hybridisation (FISH) and conventional cytogenetic methods in clinically and cytogenetically confirmed cases of microdeletion syndromes. A total of nine cases were referred to the Cytopathology and Cytogenetic Unit, Hospital Universiti Kebangsaan Malaysia (HUKM) from 2002 to 2004. They include three Prader-Willi syndrome, three DiGeorge syndrome, one Williams syndrome, one Miller-Dieker syndrome and one Kallmann syndrome. Blood samples from the patients were cultured and harvested following standard procedures. Twenty metaphases were analysed for each of the cases. FISH analysis was carried out for all the cases using commercial probes (Vysis, USA): SNRPN and D15S10 for Prader-Willi syndrome, LIS1 for Miller Dieker syndrome, ELN for Williams syndrome, KAL for Kallmann syndrome, TUPLE 1 and D22S75 for DiGeorge syndrome. Conventional cytogenetic analysis revealed normal karyotypes in all but one case with structural abnormality involving chromosomes 9 and 22. FISH analysis showed microdeletions in all of the nine cases studied. This study has accomplished two important findings ie. while the FISH method is mandatory in ruling out microdeletion syndromes, conventional cytogenetics acts as a screening tool in revealing other chromosomal abnormalities that may be involved with the disease.

     We report two cases of biphenotypic acute leukaemia diagnosed in Hospital Universiti Kebangsaan Malaysia (HUKM), their clinical, haematological characteristics and response to chemotherapy. Both patients are middle-aged ladies who presented with hepatosplenomegaly and high white cell count, mainly composed of blast cells. Their bone marrow aspirations were hypercellular comprising of more than 90% heterogenous blast cells. Cytochemical analyses show more than 3% positivity towards peroxidase, with smaller blasts showing block positivity towards PAS. Immunophenotypically, the blasts showed dual expression of CD 33 and CD 19, CD 19 and CD34, intra CD22, intra TdT and intraMPO. One of the patients showed presence of the Philadelphia chromosome on cytogenetic analysis which was confirmed by Fluorecsence In Situ Hybridisation (FISH). Molecular analysis also showed presence of the BCR-ABL fusion protein. Both patients were given combination chemotherapy consisting of daunorubicin and cytosine arabinoside.However, the patient with positive Philadelphia chromosome BCR-ABL did not achieve morphological remission after induction chemotherapy. In view of the poor prognosis of this disease, both the patients were planned for upfront peripheral blood stem cell transplantation.

    Two case reports of retinal vasculitis in presumptive ocular tuberculosis are presented. Case 1 is a 26-year-old Malay woman who had phlebitis with choroidal lesions and case 2 is a 27 year old Malay woman who had occlusive arteritis. Both subjects had positive Mantoux tests with negative systemic screen. Both responded clinically to anti-tuberculous therapy within days of commencing therapy. There was however concurrent increase in vitritis which decreased following anti-inflammatory doses of oral corticosteroids. These two cases represent a rare mode of presentation of ocular tuberculosis for which a high index of suspicion is needed. Multidrug anti-tuberculous therapy should be combined with oral corticosteroids for effective treatment.

    Evidence of ossification was previously considered a relative contraindication to cochlear implantation. It was considered difficult or impossible to achieve safe electrode insertion because of bony obstruction. Either the electrodes or the inner ear structures could be damaged. Moreover, obstructed scala tympani could limit the number of electrodes that can be inserted. The efficacy of the electrical stimulation was also questioned, as a higher current would be needed on an ossified cochlea. Finally, the neural survival in ossified cochlea is unknown. This may complicate the surgical procedure and affect the long-term outcome. However, depending on the experience of the surgeon, cochlear implantation has been attempted even in grossly ossified cochlea. Here we illustrate that cochlear implantation is safe in labyrinthitis ossificans.

     The association of human papillomavirus (HPV) with juvenile laryngeal papillomatosis has been well documented. We report two cases of juvenile laryngeal papillomatosis and correlated these cases with presence of HPV, p53 and c-erbB-2 proteins. The first case was a one-year-old male patient and the second a six-year-old female patient. Formalin-fixed paraffin-embedded biopsy specimens were tested for the presence of HPV genome by the technique of in situ hybridisation using wide spectrum and type specific biotinylated probes while the immunohistochemical expression of p53 (D07, 1:50) and c-erbB-2 (DAKO A0485, 1:300) proteins were evaluated with commercially available antibodies. Histologically the tumours in both cases showed papillary configuration of squamous papilloma. The first case detected HPV type 6, HPV type 11 and p53 protein expression while the second case showed only HPV type 6. Both cases of HPV showed positive signals confined to the nuclei in the superficial squamous epithelium. The first case showed p53 positivity seen from the basal region up to one third of the epithelium of laryngeal papillomas and the subsequent recent repeat biopsy showed the positivity of p53 had extended throughout the upper layers of the epithelium. Expression of c-erbB-2 protein was not detected in both cases. These findings were similar as in other studies where follow-up of the cases was recommended since they tend to recur.

    This is a retrospective descriptive study done to look at common presentation and method of detection of breast cancer. A total of 366 case records of patients attending the Breast and Endocrine Clinic at Hospital Kuala Lumpur were reviewed. The peak age of breast cancer presentation was 40 to 49 years (39.6%). Most (81.4%) patients presented with a lump in the breast and the lump was mainly self-detected (97.3%). The mean tumour diameter on presentation was 4.7± 3 cm. Medical staff detected the disease in 1.6% cases and 1.1% of cases were detected by mammogram. Most women detected the lump themselves, suggesting that Breast Self Examination (BSE) can be used for detection of the disease in places where there is cost and availability constrains for mammogram. Early detection with BSE can possibly offer better treatment options and quality of life despite the evidence that it does not reduce the mortality due to breast cancer.

    The reciprocal translocation t(9;22)(q34;q11) which gives rise to the Philadelphia (Ph1) chromosome and BCR/ABL fusion gene, plays a pivotal role in the diagnosis and pathogenesis of chronic myeloid leukemia (CML). In this study, we evaluated the role of fluorescence in situ hybridisation (FISH) in detecting the BCR/ABL rearrangement in CML patients. The sensitivity, specificity and detection rate of BCR/ABL gene using FISH, PCR and conventional cytogenetics (karyotyping) methods were also compared. 18 bone marrow samples of patients with clinically diagnosed CML and suspected of CML were collected. The sensitivity, specificity and positive predictive values of FISH were altogether 100% while the sensitivity, specificity and positive predictive values for conventional cytogenetics (karyotyping) were 85%, 100% and 100% respectively. Convetional cytogenetics (karyotyping) detected an additional chromosomal aberration in addition to the Ph1 chromosome. In conclusion, FISH is a highly sensitive method in detecting the BCR/ABL gene. Conventional cytogenetics (karyotyping) remains an important investigation in the work up of suspected CML patients since there is a possibility of detecting chromosomal aberrations in addition to the Ph1 translocation. Therefore, conventional cytogenetics (karyotyping) and FISH are complementary techniques and their results should be interpreted together with clinical information.

    Quality nursing care has a great impact on patient satisfaction. Quality nursing care is perceived by the post cardiac surgery patient, as the degree of physical, emotional and spiritual needs that have to be fulfilled while hospitalisation. The objective of this study was to identify factors in quality nursing care that determine post cardiac patient satisfaction. This single cross-sectional descriptive study using ‘NURSQUAL’ instrument consisted of four elements; technical competence, information giving, assurance and empathy to measure patient satisfaction with quality nursing care. It consisted of four research questions with 33 items to measure the four elements. Between January to March 2005, 52 post cardiac surgery patients from Institute Jantung Negara (IJN), who fulfilled the inclusion criteria were recruited for this study. There was a significant difference between technical competence, information giving, assurance and empathy with patient satisfaction with p value < 0.05. The element of assurance made the strongest statistically significant unique contribution to the prediction of patient satisfaction with a p value < 0.05.

    Fifty Non Insulin Dependent Diabetes Mellitus (NIDDM) patients undergoing surgery under epidural anaesthesia were studied. All patients received dextrose 5% infusion at 100 ml/hr from the period of fasting until upon arrival to the operation room. Patients were randomly divided into two groups. Patients in Group 1 (n=25) received normal saline while patients in Group 2 (n=25) were given Ringer’s lactate. Both groups received their infusion throughout the operative period up to four hours postoperatively. Blood glucose level was measured at baseline, 45 minutes intra operatively and postoperatively at 30 minutes and four hours by using a glucometer. Patients in Group 2 has a larger mean increase in blood glucose level of 1.5 mmol/L between 4 hours postoperatively and baseline compared to 0.96 mmol/L in Group 1. However, this was not statistically significant. There was no difference in the increase of mean glucose level at 30 minutes when compared to baseline. There was a significant increase in mean blood glucose level in both groups in the postoperative period when compared to baseline. This study demonstrated that patients with NIDDM receiving Ringer’s lactate has a larger increase in mean blood glucose level compared to those receiving normal saline, but the magnitude is not statistically significant.

    Sharps injury among health care workers in HUKM has received serious attention lately due to the possible transmission of diseases like HIV, Hepatits B and Hepatitis C, which can cause serious consequences for the victim. The aim of the study was to gain a deeper understanding of the emotional problems experienced by health care workers who had incurred a sharps injury and the coping strategies adopted by them to overcome the problem. A 28 item semi-structured questionnaire was designed by the supervisors and the researcher as there was no existing questionnaire to be adopted, as no research had been carried out in this area prior to this. The target group consisted of 64 health care workers of different categories working in HUKM. Data was collected over a period of five months from November 2000 to March 2001. The results of the study revealed that the most frequently injured were the staff nurses, nearly 90% of whom were emotionally upset and were worried that they might contract a disease. There was no significant difference in the emotional stress experienced by the different categories of the health care workers, all were equally upset about the injury but each category of staff adopted different methods to overcome the tragedy. Open comments and opinions about prevention and the management of the sharps injury in HUKM as given by the respondents here are taken into account. Several views given by the participants were explored and discussed. Finally, several implications for nursing and recommendations have been presented.

    Thyroid nodules are common but thyroid malignancies are not. Fine needle aspiration (FNA) cytology is a diagnostic tool used to screen patients with thyroid nodules who require surgery. We study the diagnostic accuracy of FNA as the initial diagnostic modality in the clinical assessment of thyroid nodules. Between January 1995 until December 2000, 2131 FNA of thyroid nodules were performed. Four hundred and forty-one (20.7%) of these were unsatisfactory and 1690 (79.3%) cases were satisfactory for cytological evaluation. Histopathological diagnosis were available for 361 cases. Cyto-histopathological correlation was carried out  for these cases. Our results showed a diagnostic accuracy of 96.2% with sensitivity and specificity rates of 87.7% and 98.4% res- pectively. Our positive predictive value is  93.4% and our negative  predictive value is 96.8%.  From this study, we conclude that fine needle aspiration is an important initial screening diagnostic tool for the investigation of thyroid nodules.

    Cancers of the ovary and corpus uteri afflict 5% and 3.6% Malaysian women respectively. Ovarian cancer (OC) remained the deadliest gynaecological malignancy in perimenopausal women mainly due to the lack of symptoms until the disease had spread. Ultrasonography could provide a preliminary screening allowing the clinician to tailor subsequent management and counselling for these women.  To support the basis for selective screening, a study on 517 urban disease free women aged 45 years and above, uterus-intact, non-users of HRT was undertaken. This study presented normograms of ovary, uterus and endometrium derived from entry ultrasound assessment. The sample comprised of 58.0% premenopaused and 42.0% postmenopaused women with an average age of 51.27±5.35 years old. Over two thirds were Chinese followed by Malays and Indians. The findings indicated that the average uterine size and endometrial thickness (ET) was 7.21±1.67x4.36±1.30cm and 6.36±3.73mm respectively. Premenopausal women had larger uterus compared to those postmenopaused (p

    Smoking in adolescence is a great health concern as it is related to many chronic diseases and mortality in later life. It is also associated with other high-risk behaviours among adolescents. The objective of this study was to determine the prevalence and reasons for smoking among upper secondary schoolboys. This was a cross-sectional study conducted among Form 4 and Form 5 students. Three schools in the District of Hulu Langat were identified and students from these schools were selected randomly. The students were given a self-administered questionnaire. A total of 343 students were included in the study. The prevalence of smoking among the schoolboys was 37%. Although the majority of them initiated smoking between 13-15 years old (67%), 21% of them began smoking below 12 years of age (primary school). There was a significant association between adolescent smoking and smoking among family members (p<0.05). The common reasons reported for
    initiating smoking were curiosity (69%) and peer pressure (51%). However, the common reasons for continuing smoking were stress (70%) and addiction (49%). Schoolwork was reported as the most important factor which contributed to their stress. Smoking prevention programmes should begin early in primary schools. Adolescents should be educated on effective coping strategies in managing stress and learning to be assertive.
