Ng CS, Lim LS, Chng KP, Lim P, Cheah JS, Yeo PP, et al.

Ann Acad Med Singap, 1985 Apr;14(2):297-302.
PMID: 4037689

225 women with diabetes in pregnancy were managed by a team of obstetricians, physicians (endocrinologists) and paediatricians from the National University of Singapore. A protocol of management was formulated and followed. The incidence of 1.1% or 1 in 90 pregnancies was found, with significantly higher incidence in Indians and lower in Malays. There were 37 established diabetics and 188 diagnosed during pregnancy. Of these (188), 74 were gestational diabetics. All the women were treated with Insulin and Diet or Diet alone. 177 (79%) were treated with Insulin and Diet. Blood sugar profiles were done for monitoring diabetic control. 72.8% of the women were between para 0 and 1 and 85.2% between the ages of 20 and 34. 72.5% of the women delivered at 38 weeks gestation or later. 48.9% went into spontaneous labour, 32.4% were induced and 18.7% had elective caesarean section. 62.2% of the women had labour of less than 12 hours. The overall caesarean section rate was 41.7%. There were 3 stillbirths and 2 neonatal deaths. The perinatal mortality rate was 2.2%. Thirteen babies had congenital malformations (5.8%). 77.8% of the babies had Apgar score of 7 or more at 5 minutes after delivery. 79.1% of the babies weighed between 2.5 kgm and 3.9 kgm. Pre-eclamptic toxaemia was the commonest complication in pregnancy followed by Urinary Tract Infection and Polyhydramnios. Postpartum complications in the mother were confined to 14 women (6.2%), and wound infection or breakdown was the commonest cause.

PMID: 28417133

INTRODUCTION: The objectives of this current study were to: 1) examine the prevalence and correlates of diabetes mellitus (DM) among older adults (aged 60 years and above) in a multi-ethnic population; 2) examine the prevalence and correlates of comorbid DM and depression among them; and 3) assess the effect of comorbid depression on disability, cognition and healthcare utilisation.
MATERIALS AND METHODS: Data for the current study came from the Well-being of the Singapore Elderly (WiSE) study; a single phase, cross-sectional survey conducted among Singapore residents aged 60 years and above. A total of 2565 respondents completed the survey; depression was assessed using the Automated Geriatric Examination for Computer Assisted Taxonomy (AGECAT) while a diagnosis of DM was considered if respondents stated that a doctor had diagnosed them with DM.
RESULTS: DM was reported by 25.5% of the population. The prevalence of depression was significantly higher in those diagnosed with DM than those without DM (6% vs 3%). After adjusting for sociodemographic correlates, smoking and other chronic conditions, DM remained significantly associated with depression and subsyndromal depression. However, after including measures of functioning and cognitive impairment as covariates, DM was not significantly related to depression and subsyndromal depression. Those with comorbid DM and depression were more likely to be of Indian and Malay ethnicity, aged 75 to 84 years (versus 60 to 74 years) and widowed.
CONCLUSION: Given the significant association of certain sociodemographic groups with comorbid depression among those with DM, targeted interventions for prevention and early diagnosis in these groups should be considered.
Fulltext Comparison of adults with insulin resistance (IR) in latent autoimmune diabetes versus IR in glutamic acid decarboxylase antibody-negative diabetes

Salem SD, Saif-Ali R, Muniandy S, Al-Hamodi Z, Ismail IS

Ann Acad Med Singap, 2014 Feb;43(2):107-12.
PMID: 24652431

INTRODUCTION: Insulin resistance in latent autoimmune diabetes in adults (LADA) patients is controversial. The aim of this study was to evaluate insulin resistance and its related factors (metabolic syndrome parameters) among subjects with LADA and glutamic acid decarboxylase antibodies (GADA) negative diabetes, as well as the impact of these factors on insulin resistance.

MATERIALS AND METHODS: GADA levels were investigated in 1140 diabetic patients aged between 30 and 70 years. Insulin resistance and metabolic syndrome parameters were assessed in LADA and GAD-negative diabetic patients by general linear model. In addition, the impact of metabolic syndrome factors on insulin resistance was assessed in LADA and glutamic acid decarboxylase (GAD)-negative diabetic patients.

RESULTS: LADA was diagnosed in 33 subjects from 1140 Malaysian diabetic patients (prevalence = 2.9%). The results showed that LADA patients had higher insulin resistance and high density lipoprotein cholesterol (HDLc) (P = 0.003 and 0.00017 respectively) and lower body mass index (BMI) (P = 0.007) compared to GAD-negative diabetic patients. The HDLc was associated with decreased insulin resistance in LADA patients (P = 0.041), whereas HbA1c, triacylglycerides (TG) and waist were associated with increased insulin resistance in GAD-negative diabetic patients (P = 3.6×10⁻¹², 1.01×10⁻⁵ and 0.004 respectively). HbA1c was highly associated with decreasing β-cell function in both LADA (P = 0.009) and GAD-negative diabetic subjects (P = 2.2×10⁻²⁸).

CONCLUSION: Insulin resistance is significantly higher in LADA than GAD-negative diabetic Malaysian subjects.

Dayangku Norsuhazenah PS, Baki MM, Mohamad Yunus MR, Sabir Husin Athar PP, Abdullah S

Ann Acad Med Singap, 2010 Jul;39(7):565-4.
PMID: 20697675

INTRODUCTION: In laryngectomised patients, tracheoesophageal speech is the gold standard for voice rehabilitation. This study evaluated complications related to the tracheoesophageal puncture (TEP) and the success rate in voice prosthesis after total laryngectomy at our institution over a 10-year period.
MATERIALS AND METHODS: A retrospective review of 22 TEPs was performed between January 1998 and December 2008. The timing of TEP, type of voice prosthesis, surgical and prosthesis-related complications, and TEP closure were noted.
RESULTS: Eighteen percent of the patients underwent primary and 82% secondary TEP. Our patients were predominantly males (95.4%) of Chinese descent with a mean age of 62.1 years. The types of voice prostheses used were ProvoxTM (n = 15), Voicemasters (n = 6), and Blom-Singer (n = 1). Prosthesis- related complications occurred in 77.3%. Notable complications were leakage (82.5%), prosthesis displacement (41.2%), intractable aspiration (29.4%), and aspiration of prosthesis (23.5%). The most common surgical-related complication was tracheostomal stenosis. An array of interventions comprising resizing or changing prosthesis type, nasogastric catheter insertion, stomaplasty, purse string suturing, and bronchoscopic removal of bronchial aspirated prosthesis were implemented to address encountered complications. In a mean follow-up of 34.8 months, 68.2% of patients achieved functional tracheoesophageal speech (75% of primary TEP and 67% of secondary TEP). There were 7 TEP closures indicated by persistent leakage, recurrent dislodgement, phonatory failure and, in 1 patient, persistent pain.
CONCLUSIONS: TEP has become an integral part in the rehabilitation of a laryngectomee. However, management of the frequent complications related to TEP requires specific efforts and specialistic commitments in order to treat them.
Conduction abnormalities in thyrotoxicosis--a report of three cases

Yusoff K, Khalid BA

Ann Acad Med Singap, 1993 Jul;22(4):609-12.
PMID: 8257070

Cardiac arrhythmias are common in patients with thyrotoxicosis. Conduction abnormalities have been seen in a few thyrotoxic patients, but these, in particular high grade atrioventricular (AV) block, often occur in the presence of other conditions. Three thyrotoxic patients with conduction abnormalities are described: two were associated with severe hypokalaemia and the third had congestive cardiac failure. Conditions predisposing to conduction abnormality should be identified when this occurs in a thyrotoxic patient as their correction may help resolve or explain the conduction abnormality.
Congenital cleft lip and palate in Singapore

Fong PH, Yeap CL, Lee ST

Ann Acad Med Singap, 1983 Apr;12(2 Suppl):363-5.
PMID: 6625521

Cleft lip and palate is the most common congenital abnormality seen in the Department of Plastic Surgery, Singapore General Hospital. A total of 461 operative cases seen over a period of 5 years (1977 to 1981) is analysed. There is a relatively high incidence in the Singapore population of 2.0 per 1000 live births. In both cleft lip and cleft palate deformities, there is no significant difference in the sex distribution. The cleft patterns show that 78% of the cases are unilateral clefts, 53% are left sided, 25% are right sided and 22% of the cases are bilateral clefts.
Congenital limb reduction defects: report of two cases

Malik AS, Ram SP, Seng QB, Noor AR

Ann Acad Med Singap, 1994 Nov;23(6):914-6.
PMID: 7741513

We describe two Malay male term neonates with congenital limb reduction defects. The first neonate had hypodactyly of limbs associated with micrognathia, microstomia, glossopalatine ankylosis and congenital mitral stenosis. He developed gram-negative septicaemia and died on day 14 of life. The second neonate had tetraperomelia without any other associated congenital abnormality. He developed staphylococcal skin infection which was treated conservatively. Very few cases of congenital limb reduction defects have been reported in the Asian population and we are not aware of any other reports describing Malay infants with the congenital abnormalities described in this report.
Continuing medical education

Todd D

Ann Acad Med Singap, 1987 Apr;16(2):366-9.
PMID: 3688816

With the rapid advances in medical science and increasing complexities of patient care, the need for continuing medical education (CME) is widely accepted by the profession. CME follows general and higher professional training, and should be a life long process. Teaching hospitals and postgraduate professional institutions play vital roles in organising, promoting, and monitoring this activity. CME directorates should be established. University authorities must recognise the important role of medical teachers in postgraduate and continuing medical education, and the staff establishment and terms of service should be held regularly. Medical libraries should have easy borrowing facilities. Self-assessment and audio-visual material are particularly helpful to the busy practitioner and inexpensive local or regional journals of quality can provide pertinent and up-to-date information. All charges for attending scientific meetings and educational material should be tax deductible or subsidized. The effectiveness of CME is difficult to assess and participation is almost impossible to enforce. Much depends on the standard of medical practice wanted by society. Recertification of general practitioners or specialists poses many problems. On the other hand, completion of self-assessment programmes, active participation at medical meetings, contributions to scientific literature, and membership of medical societies with built-in peer review could be monitored and regularly used to evaluate professional status.
Coronary artery calcification across ethnic groups in Singapore

Chia PL, Earnest A, Lee R, Lim J, Wong CP, Chia YW, et al.

Ann Acad Med Singap, 2013 Sep;42(9):432-6.
PMID: 24162317

INTRODUCTION: In Singapore, the age-standardised event rates of myocardial infarction (MI) are 2- and 3-fold higher for Malays and Indians respectively compared to the Chinese. The objectives of this study were to determine the prevalence and quantity of coronary artery calcification (CAC) and non-calcified plaques across these 3 ethnic groups.
MATERIALS AND METHODS: This was a retrospective descriptive study. We identified 1041 patients (810 Chinese, 139 Malays, 92 Indians) without previous history of cardiovascular disease who underwent cardiac computed tomography for atypical chest pain evaluation. A cardiologist, who was blinded to the patients' clinical demographics, reviewed all scans. We retrospectively analysed all their case records.
RESULTS: Overall, Malays were most likely to be active smokers (P = 0.02), Indians had the highest prevalence of diabetes mellitus (P = 0.01) and Chinese had the highest mean age (P <0.0001). The overall prevalence of patients with non-calcified plaques as the only manifestation of sub-clinical coronary artery disease was 2.1%. There was no significant difference in the prevalence of CAC, mean CAC score or prevalence of non-calcified plaques among the 3 ethnic groups. Active smoking, age and hypertension were independent predictors of CAC. Non-calcified plaques were positively associated with male gender, age, dyslipidaemia and diabetes mellitus.
CONCLUSION: The higher MI rates in Malays and Indians in Singapore cannot be explained by any difference in CAC or non-calcified plaque. More research with prospective follow-up of larger patient populations is necessary to establish if ethnic-specific calibration of CAC measures is needed to adjust for differences among ethnic groups.
Correlation between oestrogen receptor protein expression in infiltrating ductal carcinoma of the breast by immunohistochemistry and cytosol measurements

Looi LM, Yap SF, Cheah PL

Ann Acad Med Singap, 1997 Nov;26(6):750-3.
PMID: 9522973

Fresh frozen neoplastic tissues from 70 infiltrating ductal breast carcinomas were analysed for cytosolic oestrogen receptor (ER) protein content using a solid phase enzyme immunoassay (EIA) method based on a "sandwich" principle (Abbott ER-EIA monoclonal). Formalin-fixed, paraffin-embedded sections from the same carcinomas were examined for nuclear immunoreactivity against a monoclonal antibody for ER protein (Dako) using the standard avidin-biotin complex immunoperoxidase (IP) method after microwave antigen retrieval. The degree of ER positivity by IP was also scored according to a visual estimation of the percentage of cells expressing immunopositivity and the intensity of staining. Twenty-eight (40%) of the carcinomas were ER-positive by EIA and 34 (48.6%) were positive by IP. Twenty-five (35.7%) were ER-positive and 33 (47.1%) were ER-negative by both methods. Nine (12.9%) were ER-negative by EIA but were positive by IP, this discrepancy being ascribed to sampling inadequacy for EIA. However, 3 (4.3%) tumours were ER-positive by EIA and negative by IP. This discrepancy may be variously due to inadequate antigen retrieval, faulty technique and the possibility that the two methods do not measure identical ER proteins. IP appears to have an advantage over EIA in that it has a higher pick-up rate, does not require fresh tissue and can be applied to archival material. However, to reduce false negative estimations, it may be necessary to run IP staining using more than one ER antibody. Standardisation of the IP method for ER is desirable before this method is to be widely adopted in Malaysian laboratories. Quantitation of ER positivity by IP scoring correlated poorly with actual cytosolic levels. Caution should be exercised in attaching patient management value to visual IP scoring.
Critiques on the Objective Structured Clinical Examination

Barman A

Ann Acad Med Singap, 2005 Sep;34(8):478-82.
PMID: 16205824

INTRODUCTION: The main aim of medical education is to foster the development of clinical competence in students at all levels. Differences in experiences, methods of instruction and ambiguous forms of assessment are obstacles to attaining this goal. Dissatisfaction with the conventional methods of clinical assessment on the part of teachers and students led assessors to search for appropriate alternatives and in 1975, Harden and his colleagues introduced the objective structured clinical examination (OSCE). It is nearly impossible to have a test that satisfies all the criteria of a good test. Sometimes, a compromise has to be made between the available resources (in terms of man, money and time), and the method and quality of assessment (in terms of reliability, validity, objectivity and practicability).
METHODS: This critique on the OSCE is based on the published findings of researchers from its inception in 1975 to 2004.
RESULTS: The reliability, validity, objectivity and practicability or feasibility of this examination are based on the number of stations, construction of stations, method of scoring (checklists and/ or global scoring) and number of students assessed. For a comprehensive assessment of clinical competence, other methods should be used in conjunction with the OSCE.
CONCLUSION: The OSCE can be a reasonably reliable, valid and objective method of assessment, but its main drawback is that it is resource-intensive.
Cross-cultural adaptation and validation of Singapore Malay and Tamil versions of the EQ-5D

Wee HL, Loke WC, Li SC, Fong KY, Cheung YB, Machin D, et al.

Ann Acad Med Singap, 2007 Jun;36(6):403-8.
PMID: 17597964

INTRODUCTION: The aims of this study were to cross-culturally adapt and evaluate the validity of the Singaporean Malay and Tamil versions of the EQ-5D.
MATERIALS AND METHODS: The EQ- 5D was cross-culturally adapted and translated using an iterative process following standard guidelines. Consenting adult Malay- and Tamil-speaking subjects at a primary care facility in Singapore were interviewed using a questionnaire (including the EQ-5D, a single item assessing global health, the SF-8 and sociodemographic questions) in their respective language versions. Known-groups and convergent construct validity of the EQ-5D was investigated by testing 30 a priori hypotheses per language at attribute and overall levels.
RESULTS: Complete data were obtained for 94 Malay and 78 Indian patients (median age, 54 years and 51 years, respectively). At the attribute level, all 16 hypotheses were fulfilled with several reaching statistical significance (Malay: 4; Tamil: 5). At the overall level, 42 of 44 hypotheses related to the EQ-5D/ EQ-VAS were fulfilled (Malay: 22; Tamil: 20), with 21 reaching statistical significance (Malay: 9; Tamil: 12).
CONCLUSION: In this study among primary care patients, the Singapore Malay and Tamil EQ-5D demonstrated satisfactory known-groups and convergent validity.
Current understanding of auditory neuropathy

Boo NY

Ann Acad Med Singap, 2008 Dec;37(12 Suppl):60-3.
PMID: 19904452

Auditory neuropathy is defined by the presence of normal evoked otoacoustic emissions (OAE) and absent or abnormal auditory brainstem responses (ABR). The sites of lesion could be at the cochlear inner hair cells, spiral ganglion cells of the cochlea, synapse between the inner hair cells and auditory nerve, or the auditory nerve itself. Genetic, infectious or neonatal/perinatal insults are the 3 most commonly identified underlying causes. Children usually present with delay in speech and language development while adult patients present with hearing loss and disproportionately poor speech discrimination for the degree of hearing loss. Although cochlear implant is the treatment of choice, current evidence show that it benefits only those patients with endocochlear lesions, but not those with cochlear nerve deficiency or central nervous system disorders. As auditory neuropathy is a disorder with potential long-term impact on a child's development, early hearing screen using both OAE and ABR should be carried out on all newborns and infants to allow early detection and intervention.
Curricular trends in Malaysian medical schools: innovations within

Azila NM, Rogayah J, Zabidi-Hussin ZA

Ann Acad Med Singap, 2006 Sep;35(9):647-54.
PMID: 17051282

INTRODUCTION: Various curricular innovations were adopted by medical schools worldwide in an attempt to produce medical graduates that could meet future healthcare needs of society locally and globally. This paper presents findings on curricular approaches implemented in Malaysian medical schools, in trying to meet those needs.
METHODS: Information was obtained from published records, responses from various questionnaires, personal communication and involvement with curricular development.
RESULTS: Curricular innovations tended to be implemented in new medical schools upon their establishment. Established medical schools seemed to implement these innovations much later. Curricular trends appear to move towards integration, student-centred and problem-based learning as well as community-oriented medical education, with the Student-centred learning, Problem-based learning, Integrated teaching, Community-based education, Electives and Systematic programme (SPICES) model used as a reference. The focus is based on the premise that although the short-term aim of undergraduate medical education in Malaysia is to prepare graduates for the pre-registration house officer year, they must be able to practise and make decisions independently and be sensitive to the needs of the country's multiracial, multi-religious, and often remote communities.
CONCLUSION: In most cases, curricular planning starts with a prescriptive model where planners focus on several intended outcomes. However, as the plan is implemented and evaluated it becomes descriptive as the planners reassess the internal and external factors that affect outcomes. A common trend in community-oriented educational activities is evident, with the introduction of interesting variations, to ensure that the curriculum can be implemented, sustained and the intended outcomes achieved.
Cutaneous adnexal neoplasms in biopsy specimens processed in the Department of Pathology, University of Malaya

Jayalakshmi P, Looi LM

Ann Acad Med Singap, 1996 Jul;25(4):522-5.
PMID: 8893922

A review of consecutive biopsies of adnexal tumours from 112 patients, received by the Department of Pathology, University of Malaya, over a 13-year period was undertaken. The age range of the patients was from 1 to 84 years, with a mean of 29.8 years. Thirty-three (32%) patients were under 20 years of age. There were 68 females with a male to female ratio of 1.0:1.5. In 105 cases (93.7%), the neoplasm was solitary. The tumour measured less than 2 cm in the largest dimension in 103 cases (92%). The common sites of occurrence were the head and neck region (59%) and extremities (25%). Neoplasms of hair follicle origin accounted for 63.4% (71 cases) of all lesions. Intra-tumour deposition of amyloid was noted in one of the 14 cases of trichoepithelioma.
Delays in thrombolytic therapy in acute myocardial infarction: an audit from the east coast of peninsular Malaysia

Loke YK, Hwang SL, Tan MH

Ann Acad Med Singap, 1997 May;26(3):285-9.
PMID: 9285018

The objectives of this study were to evaluate the time delays between the onset of symptoms and admission to hospital and provision of thrombolytic therapy in patients with suspected acute myocardial infarction; and to examine the accuracy of the clinical diagnosis and the therapeutic decision on thrombolysis in these patients. An observational study of 96 patients with suspected myocardial infarction was undertaken over a period of 15 months in the Coronary Care Unit of Hospital Kuala Terengganu. Seventy per cent of the patients arrived in the hospital within 6 hours of the onset of symptoms. After arrival in the emergency room, it took a median time of 85 minutes before the administration of thrombolytic therapy. Of the 67 patients who were given thrombolysis, 46 were treated within 6 hours of the onset of symptoms. About a quarter of patients said that they had delayed seeking treatment at the hospital. Treatment delays occurring in the hospital were mainly due to admission procedures as well as late diagnosis. Eighty-one patients had confirmed myocardial infarction of whom 59 received thrombolytic therapy. Eight patients receiving thrombolytic therapy had no confirmation of myocardial infarctions. Improvements in diagnostic accuracy and reduction of delays in the provision of thrombolytic therapy could be achieved by better training of health care staff as well as by further streamlining of admission procedures.
Dengue virus infection--the Malaysian experience

George R, Lam SK

Ann Acad Med Singap, 1997 Nov;26(6):815-9.
PMID: 9522985

Since dengue was first documented in Malaysia in 1902 and made notifiable in 1973, the disease pattern has changed from major outbreaks every four years to one of increasing trend yearly. The largest outbreak was seen in 1996 with 14,255 dengue cases reported and 32 deaths. The case fatality rate varied from a high of 10.43% in 1985 when dengue type 3 was the predominant type to a low of 1.29% when dengue type 1 predominated. Severe disease patterns have been observed with dengue 2 and 3 serotypes in the country. The clinical spectrum has also been changing and multisystem involvement with more severe manifestations are being seen. Liver involvement has been documented since 1987. Fulminant hepatitis with encephalopathy can resemble Reye's syndrome. Dengue type 3 has been isolated from liver biopsy specimens. Neurological manifestations can very from irritability, convulsions, coma to peripheral neuritis. The isolation of dengue viruses from cerebrospinal fluids recently strongly suggests that dengue viruses can be neurovirulent. Adult respiratory distress syndrome was seen in three children admitted with shock. Deaths were more frequent in children in the early period but since 1982, over 50% of deaths have occurred in patients over the age of 15 years.
Diabetes mellitus in peninsular Malaysia: ethnic differences in prevalence and complications

Mustaffa BE

Ann Acad Med Singap, 1985 Apr;14(2):272-6.
PMID: 4037685

Estimated prevalence of diabetes mellitus in Malaysia was about 2%. Diabetes was most common in Indians especially males and least common in Chinese. There was a slight male preponderance seen in Malays and Indians. Positive family history was obtained in 14% of cases most commonly in Malays, almost 1/3 of whom had more than one family member with diabetes. Familial association was uncommon in Chinese. Over 50% of patients were overweight. Obesity was noted in nearly 70% of female Malays and Indians while the majority of Chinese were not overweight. More than 80% of patients were non insulin requiring. Youth onset diabetes was considered rare; those 10 years and below were estimated to be only 0.4% and below 20 years of age between 2%-4% of the diabetic population. Females were twice as common than males in this type of diabetes and familial association was greater. Malnutrition-related diabetes and pancreatic calcification were not well-documented but youth-onset non insulin requiring diabetics with mild symptoms but strong family history of diabetes were observed. More than half of hospital-based patients had evidence of complications, mainly amongst Malays and Indians. Hypertension was the most frequent associated disease followed by foot ulcers and ischaemic heart disease. Hypertension usually associated with chronic renal failure was most common amongst Malays while gangrenic ulcers and heart diseases were seen mainly in Indians. The major causes of death were chronic renal failure, myocardial infarction, ketoacidosis, stroke and septicaemia related to gangrene.(ABSTRACT TRUNCATED AT 250 WORDS)
Diarrhoeal diseases in rural Malaysia: risk factors in young children

Lye MS

Ann Acad Med Singap, 1984 Apr;13(2):156-62.
PMID: 6497315

A survey was conducted in six selected rural villages to obtain baseline data on socioeconomic status, nutrition, environmental sanitation and behavioural aspects in relation to diarrhoeal diseases, using a standard questionnaire. Subsequent to this, children 0-4 years of age were followed weekly for six months for diarrhoeal disease. Eleven variables representing socioeconomic status, nutritional status, housing condition, environmental sanitation, mother's knowledge and beliefs were investigated using stepwise logistic regression to determine significant predictors of diarrhoeal disease. Children who were below two years of age, living in conditions of poor sanitation and poor quality water supply, whose houses were prone to flooding and who had mothers whose sanitary habits were not influenced by their religious beliefs, were at significantly greater risk of diarrhoeal disease.
Disseminated Penicillium marneffei infection: a report of five cases in Singapore

Kurup A, Leo YS, Tan AL, Wong SY

Ann Acad Med Singap, 1999 Jul;28(4):605-9.
PMID: 10561784

Penicillium marneffei has emerged as an important opportunistic pathogen in HIV-infected patients in Southeast Asia. We report the first 5 cases of P. marneffei diagnosed in Singapore. All the patients were HIV-infected and were either Thai nationals or had frequently travelled to Thailand. Fever, weight loss, anaemia and papular skin lesions were common clinical manifestations in our patients, all of whom had the organism isolated from blood. Skin biopsy specimens showed histological evidence of P. marneffei in 2 patients. In 1 patient each, the organism grew in cultures of specimens from bone marrow and respiratory secretions. Amphotericin B therapy followed by itraconazole were used in 3 of our 5 patients and was associated with good clinical response and outcome.
