Thyroid hormones and autoantibodies in pregnant patients with thyroid diseases

Goh KH, Ng ML, Roslan BA, Tan TT, Nasri BN, Khalid BA

Ann Acad Med Singap, 1993 Jul;22(4):539-43.
PMID: 8257054

Serum concentrations of thyroid stimulating hormone (TSH) and thyroid autoantibodies in pregnant patients with thyroid disease at various stages of pregnancy were determined by in-house ELISAs. In normal pregnancy, serum TSH levels were significantly elevated (p < 0.05) from 13 weeks of gestation. The normal reference ranges for TSH for the second (0.6-5.0 mIU/l) and third trimester (0.6-5.6 mIU/l) were significantly higher (p < 0.05; p < 0.01 respectively) compared to 0.4-4.5 mIU/l for the first trimester. In pregnant thyroid patients, serum TSH levels correlated highly (p < 0.001) to T4 (r = 0.740), FT4I (r = 0.683) and MicAb (microsomal antibodies) (r = 0.825) but weaker (p < 0.01) to T3 (r = -0.512), FT3I (r = 0.520) and TgAb (thyroglobulin antibodies) (r = 0.618). Thus, measurement of TSH with the highly sensitive ELISA (enzyme linked immunosorbent assay) would form a useful first line test for thyroid dysfunction in pregnancy while measurement of thyroid autoantibodies would aid in the diagnosis of autoimmune hypothyroidism.

Fulltext Variations of serum prolactin levels in Malay women from premenarche to the postmenopause

Rajikin MH, Satgunasingam N

Med J Malaysia, 1984 Jun;39(2):135-8.
PMID: 6513852

A double-antibody radioimmunoassay technique has been used to investigate the serum prolactin (hPRL) level in Malay females from premenarche to the postmenopause. The results showed that the hPRL level (mena ± SEM) in the premenarchal, postmenarchal and late pubertal/reproductive subjects were 23.6 ± 2.3, 19.1 ± 2.0 and 22.7 ± 1.9 ng/ml respectively. In premenopausal women, hPRL level (11.8 ± 2.4 ng/ml) was significantly reduced (p < 0.01) compared to that of late pubertal group; the level declined even further after menopause (9.5 ± 1.7 ng/ml). Although the difference in the mean prolactin levels between premenopause and postmenopause were not significant, 73% of the postmenopausal women had serum prolactin concentrations below 10 ng/ml compared to 44% of the premenopausal and 10% in late pubertal group.

Growth of weight, length and crown-rump length of Malaysian infants and pre-school children

Chen ST

J Singapore Paediatr Soc, 1990;32(3-4):65-80.
PMID: 2133760

126 Malaysian children, 65 boys and 61 girls from higher income families were followed-up regularly from birth to six years of age in the University Hospital, Kuala Lumpur. Their physical growth, development, dietary and illness patterns were measured at each visit. The study confirms the observations of previous studies that boys are, on the average, heavier and taller than girls and that Asians are smaller in size with relatively shorter legs compared with children of European ancestry. These racial differences are due to a combination of genetic and environmental differences. Since there are genetic differences in the size and shape of children, standards applicable to the specific population should be used to obtain the best results when assessing the health of an individual child. The growth charts presented in this paper can be used as standards to monitor the growth of Asian infants and pre-school children.

Growth of arm circumference and triceps skinfold of Malay children from birth to six years of age

Chen ST

J Singapore Paediatr Soc, 1990;32(3-4):87-96.
PMID: 2133762

126 Malaysian children, 65 boys and 61 girls from higher income families were followed-up regularly from birth to six years of age in the University Hospital, Kuala Lumpur. The study shows that for boys and girls, there is a progressive increase in the left mid-upper arm circumference from birth to six years of age. However the rate of growth is not even, being most rapid during the first four month of infancy, then rapidly decreases during the middle third of infancy and thereafter it decreases slowly and by the second year of life, there is hardly any increase in the arm circumference. The left triceps skinfold thickness curves for boys and girls rise rapidly after birth to reach a peak at about three to five months before commencing to decline and then flatten off from the second year of life. The study also shows that on the whole, boys have slightly bigger arm circumference than girls during the first two years of life. From two years of age, girls on the average have more fat than boys. However this difference is statistically not significant at the ages tested. This paper also presents the left mid-upper arm circumference and left triceps skinfold percentile charts of Malaysian boys and girls from birth to six years of age.

Ethnic and other factors affecting birthweight in Singapore

Viegas OA, Ratnam SS, Cole TJ

Int J Gynaecol Obstet, 1989 Aug;29(4):289-95.
PMID: 2571528

Data on 1800 term babies, 600 from each of the Chinese, Malay and Indian racial groups, were used to identify the factors affecting birthweight in Singapore. After adjustment for gestation, maternal height and other variables, the mean Indian birthweight was 100 g less than for the Chinese (P less than 0.001), 0.001), while the Malays averaged 33 g less than the Chinese. The shortfall in Indian birthweight is thought to be due, at least partly, to environmental factors.

Fulltext Peak expiratory flow rate (PEFR) of Malaysian children

Omar AH, Henry RL

Med J Malaysia, 1991 Mar;46(1):82-7.
PMID: 1836043

Prediction equations for peak expiratory flow rate (PEFR) of Malay, Chinese and Indian children were obtained by analysing 1020 PEFR recordings of children free of respiratory symptoms and illnesses. Boys had significantly higher PEFR than girls. For both sexes the highest levels of PEFR were observed in Malays and the lowest in Indians. The differences between Malay and Chinese boys were not statistically significant but the levels of PEFR for Malay and Chinese boys were significantly higher than those for Indian boys. In girls the differences among the ethnic groups were not statistically significant. Although ethnic differences were observed in boys these differences might not be clinically important. A common prediction equation for each sex should be both practical and accurate. When compared with predicted levels for white American and Australian children the predicted levels of PEFR of Malaysian children were found to be lower; these differences could be clinically important and the use of standards for Western children when assessing Malaysian children might not be appropriate.

Fulltext Staphylococcus aureus carriage in selected communities and their antibiotic susceptibility patterns

Norazah A, Lim VKE, Munirah SN, Kamel AGM

Med J Malaysia, 2003 Jun;58(2):255-61.
PMID: 14569746

The carriage and antibiotic susceptibility patterns of Staphylococcus aureus in the community were determined. Nasal, throat and axillary swabs were taken from 100 healthy adults and 90 disabled nursing home inmates. Antibiotic disc susceptibility testing was conducted following the NCCLS method. Staphylococcus aureus carriage was noted in 29% of healthy adults and 47.7% of nursing home inmates. Out of 79 strains, resistance to antibiotics were as follows; penicillin (92.4%), genetamicin (2.5%), tetracycline (6.3%), fusidic acid (11.3%), erythromycin (3.8%), pefloxacin (5.1%), mupirocin (3.8%), amikacin (3.8%), ciprofloxacin (2.5%) and chloramphenicol (2.5%). Methicillin-resistant Staphylococcus aureus was not isolated. Multiple colonizations and multi-antibiotic resistant Staphylococcus aureus were shown to occur in healthy individuals without risk factors and not previously hospitalized.

Fulltext Assessment of autosomal and male DNA extracted from casework samples using Casework Direct Kit, Custom and Maxwell 16 System DNA IQ Casework Pro Kit for autosomal-STR and Y-STR profiling

Hakim HM, Khan HO, Ismail SA, Ayob S, Lalung J, Kofi EA, et al.

Sci Rep, 2019 10 10;9(1):14558.
PMID: 31601905 DOI: 10.1038/s41598-019-51154-4

Short repetitive regions in autosomal and Y chromosomes known as short tandem repeats (STRs) are currently used for DNA profiling in crime investigations. However, DNA profiling requires a sufficient quality and quantity of DNA template, which is often not obtained from trace evidence or degraded biological samples collected at the scene of a crime. Here, we assessed autosomal and male DNA components extracted from crime scene and mock casework samples using the Casework Direct Kit, Custom and compared the results against those obtained by extraction of matching samples using well-established Maxwell 16 System DNA IQ Casework Pro Kit. The quantity and quality of extracted DNA obtained using both Casework Direct Kit, Custom and Maxwell 16 System DNA IQ Casework Pro Kit were analyzed using PowerQuant Systems followed by autosomal and Y-chromosome STR profiling using GlobalFiler Express PCR Amplification Kit and PowerPlex Y23 System, respectively. Our results showed that the Casework Direct Kit and Maxwell 16 DNA IQ Casework Pro Kit have more or less equal capacity to extract inhibitor free DNA, but that the latter produces slightly better quality and more DNA template and subsequently higher numbers of STR allele calls for autosomal and Y-STR analyses. Nonetheless, the Casework Direct Kit, Custom is the quicker and cheaper option for extraction of good, clean DNA from high content material and might best be used for extraction of reference samples. Such reference DNA samples typically come from buccal swabs or freshly drawn blood. So, in general, they can confidently be expected to have a high nucleic acid content and to be inhibitor-free.

Dental age estimation in Malay children based on all permanent teeth types

Yusof MY, Thevissen PW, Fieuws S, Willems G

Int J Legal Med, 2014 Mar;128(2):329-33.
PMID: 23370574 DOI: 10.1007/s00414-013-0825-8

The applicability of the Willems et al. model was verified on a collected sample of Malay (Malaysian nationality) children. This sample was split in a reference sample to develop a Malay-specific prediction model based on the Willems et al. method and in a test sample to validate this new developed model. Next, the incorporation of third molars into this model was analyzed. Panoramic radiographs (n = 1,403) of Malay children aged between 4 and 14.99 years (n = 702) and subadults aged between 15 and 23.99 years (n = 701) were collected. The left mandibular seven permanent teeth of the children were scored based on the staging technique described by Demirjian and converted to age using the Willems et al. method. Third molar development of all individuals was staged based on the technique described by Gleiser and Hunt modified by Kohler. Differences between dental age and chronological age were calculated and expressed in mean error (ME), mean absolute error (MAE), and root mean square error (RMSE). The Willems et al. model verified on the collected Malay children overestimated chronological age with a ME around 0.45 year. Small differences in ME, MAE, and RMSE between the verified Malay-specific prediction model and the Willems et al. model were observed. An overall neglected decrease in RMSE was detected adding third molar stages to the developed permanent teeth model.

Pediatric Perceived Cognitive Functioning: Psychometric Properties and Normative Data of the Dutch Item Bank and Short Form

Marchal JP, de Vries M, Conijn J, Rietman AB, IJsselstijn H, Tibboel D, et al.

J Int Neuropsychol Soc, 2019 09;25(8):845-856.
PMID: 31179957 DOI: 10.1017/S1355617719000572

OBJECTIVE: With increasing numbers of children growing up with conditions that are associated with acquired brain injury, efficient neuropsychological screening for cognitive deficits is pivotal. Brief self-report measures concerning daily complaints can play an important role in such screening. We translated and adapted the pediatric perceived cognitive functioning (PedsPCF) self- and parent-report item bank to Dutch. This study presents (1) psychometric properties, (2) a new short form, and (3) normative data for the short form.
METHODS: A general population sample of children and parents was recruited. Dimensionality of the PedsPCF was assessed using confirmatory factor analyses and exploratory bifactor analyses. Item response theory (IRT) modeling was used to evaluate model fit of the PedsPCF, to identify differential item functioning (DIF), and to select items for the short form. To select short-form items, we also considered the neuropsychological content of items.
RESULTS: In 1441 families, a parent and/or child participated (response rate 66% at family level). Assessed psychometric properties were satisfactory and the predominantly unidimensional factor structure of the PedsPCF allowed for IRT modeling using the graded response model. One item showed meaningful DIF. For the short form, 10 items were selected.
CONCLUSIONS: In this first study of the PedsPCF outside the United States, studied psychometric properties of the translated PedsPCF were satisfactory, and allowed for IRT modeling. Based on the IRT analyses and the content of items, we proposed a new 10-item short form. Further research should determine the relation of PedsPCF outcomes with neurocognitive measures and its ability to facilitate neuropsychological screening in clinical practice.

Fulltext Extreme Thrombocytosis in a Child: Laboratory Approaches and Diagnostic Challenges

Zulkafli Z, Janaveloo T, Wan Ab Rahman WS, Hassan MN, Abdullah WZ

Oman Med J, 2019 Jul;34(4):336-340.
PMID: 31360323 DOI: 10.5001/omj.2019.65

Thrombocytosis in children as well as in adult is defined as platelet count ≥ 450 × 109/L, and it is usually a reactive feature to various medical disorders. However, extreme thrombocytosis (platelet count ≥ 1000 × 109/L) is an uncommon finding among pediatric and adult patients, which may indicate more than a reactive phenomenon. We describe a case of a five-year-old boy who was admitted due to recurrent epistaxis. He had no history of allergic tendency or trauma. Physical examination was unremarkable except for shotty neck nodes. Laboratory results at presentation showed normal hemoglobin and total leukocyte count with eosinophilia (0.92 × 109/L), and extreme thrombocytosis. Other relevant investigations including coagulation profile, serum ferritin, liver, and renal function tests were all within normal ranges. Stool samples for ova and cysts were negative. The peripheral blood smear and bone marrow aspirate confirmed thrombocytosis with increased megakaryocytic proliferation and no artefactual reasons for the high platelets such as red blood cell fragments. Different causes of thrombocytosis in childhood were investigated after considering the possible differential diagnoses for extreme thrombocytosis.

Chee, Yik Chang

Borneo Journal of Medical Sciences, 2020;14(3):61-62.
MyJurnal

A 24-year-old female complained of a 2-week history of fever and right-eye swelling. There was no ocular pain, blurring of vision, or history of prior trauma to the affected eye. On examination, she was febrile and not in respiratory distress. The right lower eyelid appeared swollen with skin erythema (Figure 1), while the visual acuity was normal. The white cell count was 14.8 × 103/μL (normal range = 4 – 10 × 103/μL). Her liver and renal function tests were within the normal range. The abdominal ultrasonography revealed multiple splenic microabscesses, while chest radiograph was normal. Contrast-enhanced computed tomography of the orbit showed a right lower eyelid abscess with extension into the right nasolacrimal duct (Figure 2). Incision and drainage of the eyelid abscess were performed and the culture of the pus, as well as the blood, yielded Burkholderia pseudomallei. She received intravenous ceftazidime 2 g every 8 hours for 4 weeks, followed by oral trimethoprim-sulfamethoxazole for 20 weeks’ duration. The right eyelid abscess and splenic microabscesses resolved completely post-treatment. Please interpret the figures and suggest the provisional diagnosis.

Re-visiting pH-adjusted potassium to avoid hypokalemic crisis during management of diabetic ketoacidosis: A conceptual framework

Usman A, Shaikh MF, Dujaili JA, Mustafa N, Gan SH

Diabetes Metab Syndr, 2021 Mar 05;15(2):573-580.
PMID: 33706189 DOI: 10.1016/j.dsx.2021.03.001

BACKGROUND AND AIMS: Diabetic ketoacidosis (DKA) treatment guidelines recommend to initiate potassium-replacement when serum potassium (SK) drops within normal range, and to withhold insulin if SK is below normal. Despite strict recommendations, hypokalemia is frequently observed in DKA.
METHODS: Scientific literature was thoroughly searched to find 1) DKA treatment guidelines, 2) studies reporting hypokalemia in DKA, 3) and literature elaborating mechanisms involved in hypokalemia.
RESULTS: Acidosis affects SK and its regulators including insulin, catecholamines and aldosterone. Current conceptual framework is an argument to gauge the degree of hypokalemia before it strikes DKA patients utilizing SK level after adjusting it with pH. Suggested approach will reduce hypokalemia risk and its associated complications. The nomogram calculates pH-adjusted potassium and expected potassium loss. It also ranks hypokalemia associated risk, and proposes the potassium-replacement rate over given time period. The differences between current DKA treatment guidelines and proposed strategy are also discussed. Moreover, reasons and risk of hyperkalemia due to early initiation of potassium replacement and remedial actions are debated.
CONCLUSION: In light of proposed strategy, utilizing the nomogram ensures reduced incidence of hypokalemia in DKA resulting in improved clinical and patient outcomes. Pharmacoeconomic benefits can also be expected when avoiding hypokalemia ensures early discharge.

Fulltext Nutritional status and self-reported nutrition education exposure in women with gestational diabetes mellitus at primary health clinic

Nurul-Alia Samiun, Barakatun-Nisak Mohd Yusof, Irmi Zarina Ismail, Norfarhana Mohd Anuar, Winnie Chee Siew Swee

Journal of Clinical and Health Sciences, 2019;4(2):66-74.
MyJurnal

Introduction: Optimal nutritional status is of utmost importance not only for foetal
development but also to maintain normoglycemia in women with gestational diabetes mellitus
(GDM). This cross-sectional study described the nutritional status of women with GDM and
explored whether self-reported nutrition education (NEd) exposure before a GDM diagnosis
would be able to promote better nutrition status. Methods: GDM women (n= 60; age= 31.6 ±
5.0 years) diagnosed between 13th and 28th week of gestation participated in the study. We
assessed nutritional status that included anthropometric and blood pressure assessments,
biochemical data, and dietary intake. The respondents self-reported their NEd exposure before
a GDM diagnosis was made. Results: The pre-pregnancy BMI of the participants was 27.9 ±
6.8 kg/m2
, which was categorised as overweight. Total (4.3 ± 5.6 kg) and rate (0.2 ± 0.3
kg/week) of gestational weight gain were within the recommendations. Glycemic parameters
and blood pressure were also within the normal range. Nevertheless, they had high intakes of
fat (35.5%) and sugar (14.4%) proportionate to their energy intake. They did not meet the
recommended nutrient intakes for fibre, calcium, and iron. Only 28.3% of women had prior
NEd exposure. Among them, almost all (94.1%) had recurrent GDM. Those with NEd
exposure had lower pre-prandial blood glucose profiles, systolic blood pressure, and
proportion of protein intake from energy than those without (p< 0.05). Conclusions:
Suboptimal maternal nutritional status and low exposure to NEd are evident in women with
GDM. Those with self-reported NEd exposure had better parameters of nutritional status. The
findings recognised the need of having proper nutrition education for women who are at high
risk of GDM since at early pregnancy.

Ulcerative colitis with concomitant primary sclerosing cholangitis

Mohamed AK, Seow CE

Med J Malaysia, 2020 11;75(6):756-758.
PMID: 33219195

Primary sclerosing cholangitis (PSC) is the most common liver disease and known hepatobiliary complication of ulcerative colitis (UC). Concomitant PSC in UC is associated with increased risk of rapid progression of primary sclerosing cholangitis, and malignancy including colon carcinoma as well as hepatobiliary carcinoma. We report a case of a 26-year-old woman who was diagnosed as ulcerative colitis during her second pregnancy. Her liver function test showed a significant elevation of alkaline phosphatase (ALP) and gamma glutamyl transferase (GGT) with other parameters being within normal range. A clinical suspicion of primary sclerosing cholangitis was then made. Magnetic resonance cholangiopancreticography (MRCP) revealed beaded appearance of the right and left intrahepatic ducts with focal narrowing seen at the ducts, suggestive of primary sclerosing cholangitis. She was subsequently started on oral Ursodeoxycholic acid (UDCA) with improvement in her liver function test within 3 weeks of initiation of treatment.

Fulltext Can we IMPROVE cardiovascular outcomes through phosphate lowering in CKD? Rationale and protocol for the IMpact of Phosphate Reduction On Vascular End-points in Chronic Kidney Disease (IMPROVE-CKD) study

Lioufas N, Toussaint ND, Pedagogos E, Elder G, Badve SV, Pascoe E, et al.

BMJ Open, 2019 02 21;9(2):e024382.
PMID: 30796122 DOI: 10.1136/bmjopen-2018-024382

INTRODUCTION: Patients with chronic kidney disease (CKD) are at heightened cardiovascular risk, which has been associated with abnormalities of bone and mineral metabolism. A deeper understanding of these abnormalities should facilitate improved treatment strategies and patient-level outcomes, but at present there are few large, randomised controlled clinical trials to guide management. Positive associations between serum phosphate and fibroblast growth factor 23 (FGF-23) and cardiovascular morbidity and mortality in both the general and CKD populations have resulted in clinical guidelines suggesting that serum phosphate be targeted towards the normal range, although few randomised and placebo-controlled studies have addressed clinical outcomes using interventions to improve phosphate control. Early preventive measures to reduce the development and progression of vascular calcification, left ventricular hypertrophy and arterial stiffness are crucial in patients with CKD.
METHODS AND ANALYSIS: We outline the rationale and protocol for an international, multicentre, randomised parallel-group trial assessing the impact of the non-calcium-based phosphate binder, lanthanum carbonate, compared with placebo on surrogate markers of cardiovascular disease in a predialysis CKD population-the

nd-points (IMPROVE)-CKD study. The primary objective of the IMPROVE-CKD study is to determine if the use of lanthanum carbonate reduces the burden of cardiovascular disease in patients with CKD stages 3b and 4 when compared with placebo. The primary end-point of the study is change in arterial compliance measured by pulse wave velocity over a 96-week period. Secondary outcomes include change in aortic calcification and biochemical parameters of serum phosphate, parathyroid hormone and FGF-23 levels.
ETHICS AND DISSEMINATION: Ethical approval for the IMPROVE-CKD trial was obtained by each local Institutional Ethics Committee for all 17 participating sites in Australia, New Zealand and Malaysia prior to study commencement. Results of this clinical trial will be published in peer-reviewed journals and presented at conferences.

Reference ranges for D-dimer levels in Malaysian women in the three trimesters of pregnancy

Mohmad Sallih N, Subbiah I, Ali A, Jackson N

Malays J Pathol, 2019 Apr;41(1):7-13.
PMID: 31025632

INTRODUCTION: Plasma D-dimer levels rise progressively during pregnancy, so one cannot apply normal reference ranges, or the usual cut-off value (500ng/mL), for the exclusion of venous thromboembolism (VTE), in pregnant women. This study was carried out in pregnant Malaysian women in order to build applicable reference ranges for D-dimer.
MATERIALS AND METHODS: A cross-sectional study was conducted to measure D-dimer in healthy pregnant women, and a non-pregnant control group, using the quantitative HaemosIL D-dimer HS500 assay. Reference ranges were derived using CLSI 'Robust' methods, and differences between group medians were tested using the Kruskal-Wallis and Mann-Whitney U tests.
RESULTS: Plasma D-dimer levels were measured in 92 pregnant women (distributed across the three trimesters)and 31 control women. The medians (and reference ranges) in ng/mL were: control 265 (<799); first trimester 481 (<1070); second trimester 1073 (357-1748); 3rd trimester 1533 (771-2410). There were significant differences between the D-dimer levels of each group and each of the other groups (P<0.001).
CONCLUSIONS: Reference ranges for D-dimer in pregnant Malaysian women have been establised by this study. Whether these ranges can be used to determine cut-off levels for the exclusion of VTE at different stages of pregnancy is doubtful, as the levels rise continuously through pregnancy, and some very high outlying values occur in apparently normal near-term pregnancy.
