Fulltext The effect of a user-guided request form for chest radiographs in a neonatal intensive care unit

Med J Malaysia, 2004 Dec;59(5):598-603.

PMID: 15889561

The objectives of this prospective, observational study were to determine the current indications of requesting chest radiograph in sick infants in a neonatal intensive care unit (NICU) and the effect of a user-guided request form for chest radiographs of sick infants. During the three-month study period, a total of 423 chest radiographs were requested on 159 sick newborn infants in the intensive area of this NICU. A majority (55.6%) of these chest radiographs were performed to verify positions tips of either central catheters (27.4%) or endotracheal tubes (28.1%). The number of chest radiographs done during the period when the user-guided request forms were utilised was significantly lower (1.24 per patient) than before (1.37 per patient) or after (1.58 per patients) the period when these forms were in use (p=0.01). The rate of radiological abnormalities detected in radiographs requested to verify position of tips of endotracheal tubes were significantly greater during the period when user-guided forms were used than when they were not (p=0.01). A significantly higher proportion of changes in management were instituted when the user-guided forms were in use than during the period when they were not used (p=0.03). We conclude that a user-guided radiographic request form helps doctors in NICU to carry out their management more effectively.

Fulltext Turn-around-time of radiographs in a neonatal intensive care unit

PMID: 16379189 MyJurnal

A quality assurance study was carried out prospectively in two phases at the Neonatal Intensive Care Unit (NICU) of Hospital Universiti Kebangsaan Malaysia. The objectives of the study were to determine the turn-around-time (TAT) of radiographs requested for infants undergoing intensive care treatment in the NICU and the effects of a standard operating procedure introduced based on initial findings of first phase of the study on subsequent TAT. The TAT was defined as the time taken for the radiograph to be ready for viewing after the attending doctor had requested for it to be done on an infant. During phase one of the study, none of the requested radiographs was ready to be viewed by the doctors within the standard TAT of 45 minutes. The problems identified were ward staffs delay in sending request forms to the radiology department, radiographers' delay in shooting and processing the films, and delay by NICU porter in collecting the processed films. Based on these findings, a standard operating procedure (SOP) was drawn up jointly by the staff of NICU and Department of Radiology. During phase two of the study conducted at one month after implementation of the SOP, there was a reduction of TAT by 50%. However, only 3 (4.3%) of the radiographs achieved the standard TAT. The main problems identified during phase two were delay in sending request forms and in collecting processed radiographs by the porter system. The dismal TAT of radiographs in NICU was related primarily to human behaviour. Besides continuous staff education, replacement of the porter system with electronic system may improve the TAT.

Successful clot lysis using low dose of streptokinase in 22 neonates with aortic thromboses

Cheah FC, Boo NY, Rohana J, Yong SC

J Paediatr Child Health, 2001 Oct;37(5):479-82.

PMID: 11885713

OBJECTIVE: To determine whether intravenous infusion of low dose of streptokinase was effective in lysing umbilical arterial catheter (UAC)-associated aortic thrombi.

METHOD: A prospective cohort study of 31 consecutive newborn infants with UAC-associated aortic thrombi which were detected by abdominal ultrasonography after removal of UAC. Twenty-two infants were treated with intravenous infusion of low dose (1000 U/h) streptokinase, while nine others were not treated due to various contra-indications. Thrombolysis occurred after a mean interval of 2.2 days (standard deviation (SD) = 1.8) in the treated infants. In the untreated infants, spontaneous thrombolysis occurred significantly later, after a mean interval of 16.9 days (SD = 14.7) (95% confidence intervals of difference between mean intervals - 26.0, - 3.4; P = 0.02). Only one treated infant developed mild bleeding directly attributed to streptokinase therapy.

CONCLUSION: Low dose streptokinase infusion was effective and safe in thrombolysing UAC-associated aortic thrombi.

Fulltext The usefulness of early ultrasonography, electroencephalography and clinical parameters in predicting adverse outcomes in asphyxiated term infants

Ong LC, Kanaheswari Y, Chandran V, Rohana J, Yong SC, Boo NY

Singapore Med J, 2009 Jul;50(7):705-9.

PMID: 19644627

The early identification of asphyxiated infants at high risk of adverse outcomes and the early selection of those who might benefit from neuroprotective therapies are required. A prospective observational study was conducted to determine if there were any early clinical, neuroimaging or neurophysiological parameters that might predict the outcome in term newborns with asphyxia.

The aim of this study was to compare the response and survival rates of term infants with persistent pulmonary hypertension of the newborn (PPHN) on high frequency oscillatory ventilation (HFOV) treated with either inhaled nitric oxide (iNO) or intravenous magnesium sulphate (MgSO4).

Fulltext Transient abnormal myelopoeisis in newborns with Down syndrome

Zarina AL, Hamidah A, Yong SC, Rohana J, Hamidah NH, Azma RZ, et al.

Malays J Pathol, 2007 Dec;29(2):107-11.

PMID: 19108403 MyJurnal

Transient abnormal myelopoeisis (TAM) is a haematological phenomenon commonly seen in newborns with Down syndrome. Although the majority show spontaneous resolution, this condition should not be dismissed too readily as there have been associated fatalities. Furthermore, even for those who do show spontaneous resolution, a significant percentage will develop acute megakaryoblastic leukaemia within the next few years of life. We report a series of four patients with TAM who presented with hepatosplenomegaly and leucocytosis detected on preliminary investigations.

Fulltext Unbalanced chromosomal translocation: a cause of recurrent spontaneous abortion

Zarina AL, Jamil MA, Ng SP, Rohana J, Yong SC, Salwati S, et al.

Med J Malaysia, 2006 Jun;61(2):260-2.

PMID: 16898328 MyJurnal

Recurrent spontaneous abortion, defined as three consecutive abortions, occurs in approximately 1% to 2% of couples. Although the cause is unknown in up to 50% of cases, about 5% of these couples are found to be a balanced translocation carrier. We report a case in which the mother was identified to be a translocation carrier following the birth of a baby with multiple congenital abnormalities.

Obtaining assent for research involving children in Malaysia: a position statement from the Academy of Medicine of Malaysia College of Paediatrics

Khoo EJ, Zilfalil BA, Thong MK, Yong SC, Chee SC, Lee JK, et al.

Med J Malaysia, 2024 Jul;79(4):494-497.

PMID: 39086351

The Academy of Medicine of Malaysia College of Paediatrics acknowledges the role of children in research and this position statement explores the ethical considerations in obtaining assent from minors in the Malaysian context. It highlights the importance in respecting children's agency and navigating cultural complexities. The College proposes flexibility in the minimum age for assent of at least nine years old, while emphasising the need for a tailored assent procedure. Addressing language and cultural diversities and expanding local empirical research on a formal assent process are some building blocks in developing a standardised nationwide process in obtaining assent from children.
