Med J Malaysia, 2005 Aug;60 Suppl D:32-4.

Members of the medical profession are expected to be well aware and abide by the revised code of ethics adopted by the Malaysian Medical Council on 9th December 1986. Under the Act Council may, in the exercise of its disciplinary jurisdiction, impose punishments related to misconduct or malpractices. When a complaint or information is made against any practitioner, the President shall forward such complaint to the Chairman of the Preliminary Investigation Committee. The procedure of the disciplinary inquiry is not exactly like those in the court of law but the same principle of justice is adhered to and all evidence used to make a decision must only be those that are admissible in accordance with the rule of evidence.

Radiocontrast-induced nephropathy in a pair of xiphaomphalopagus conjoined twins during the neonatal period

Boo NY, Mahmud MN, Samad SA

Acta Paediatr Scand, 1991 6 1;80(6-7):735-7.

PMID: 1867096

One of the babies in a pair of xiphaomphalopagus conjoined twins developed oliguria, transient rise in serum creatinine and persistent nephrogram on the sixth day of life following injection of radiocontrast medium for computerised axial tomography scanning of the urinary system. The other twin was spared but developed hypertension and "dialysed" the oliguric twin. The renal profiles of both neonates subsequently remained normal until they reached adequate weight for surgical separation at a later date.

INTRODUCTION: The study was performed to determine the psychological problems in children with idiopathic nephrotic syndrome (INS) while they were on steroid therapy, as compared to healthy children.

METHODS: This prospective cohort study was conducted in a paediatric clinic of a tertiary hospital. Parents of the participants in the INS group and control group (comprising children without chronic illness) completed questionnaires using the Child Behavioural Checklist (CBCL). The CBCL measures a range of age-specific emotional and psychological problems, including internalising and externalising domains. Analyses of the CBCL scores between groups were done using Mann-Whitney U test.

RESULTS: A total of 140 children were recruited with an equal number in the INS and control groups. There was a significant difference in the mean total CBCL scores between the INS group and the control group, specifically in the withdrawal, somatic, anxious and aggressiveness subdomains. Similar findings were demonstrated in correlation between total psychological problems and corticosteroid dosage. In the INS group, steroid dose and cushingoid features were found to have a significant positive association with internalising psychological problems.

CONCLUSION: Children with INS on corticosteroid treatment showed an increase in internalising and externalising scores, as compared to healthy children.

Fulltext Jaundice clearance and cholangitis in the first year following portoenterostomy for biliary atresia

Sixty-one patients with biliary atresia, who underwent portoenterostomy (PE) between 1992 to 1998 in the Institute of Pediatrics, Kuala Lumpur and were followed for a period of one year, were studied to analyze the factors associated with jaundice clearance and cholangitis following PE. Sex distribution was equal. Majority of patients were Malays. Mean age in days at admission to the surgical ward was 66.90 +/- 23.36 and mean age at PE was 75.85 +/- 24.05. At the end of one-year follow-up, six patients (10%) had died, 35 (57%) developed one or more attacks of cholangitis, 35 (57%) had portal hypertension, eight (13%) liver failure and six patients had esophageal variceal bleeding. Thirty-three patients (54%) had jaundice clearance with a mean clearance time of 85 days after PE. The study shows that when the ductules in the porta hepatis were < 150 mu in size, persistence of jaundice after PE and the incidence of cholangitis in the first post-operative year were higher; patients with cholangitis in the first year had lower rate of jaundice clearance. Jaundice clearance was achieved in more patients when their postnatal age at the time of PE was lower but the relationship was not linear. Age at PE also did not have a linear temporal relationship to the incidence of cholangitis and the size of portal ductules. Prospective, multi-center based local studies on a bigger patient population are needed to identify other indicators of successful outcome following PE. This would help to define the indications for primary liver transplantation in the local population.

The control effects on the convection dynamics in a viscoelastic fluid-saturated porous medium heated from below and cooled from above are studied. A truncated Galerkin expansion was applied to balance equations to obtain a four-dimensional generalized Lorenz system. The dynamical behavior is mainly characterized by the Lyapunov exponents, bifurcation, and isospike diagrams. The results show that within a range of moderate and high Rayleigh numbers, proportional controller gain is found to enhance the stabilization and destabilization effects on the thermal convection. Furthermore, due to the effect of viscoelasticity, the system exhibits remarkable topological structures of regular regions embedded in chaotic domains.

Data on the mineral composition and content of one heavy metal measured in three different fruit flours prepared from ripe and unripe fruits (pulp and peel) are presented. The mineral composition (sodium (Na), potassium (K), magnesium (Mg), calcium (Ca), zinc (Zn), copper (Cu), iron (Fe) and manganese (Mn)) and content of one heavy metal (lead (Pb)) of the flours were analyzed by atomic absorption spectrophotometry. The analysis showed that the data can be used for differentiation between different fruits and stages of ripeness, as revealed by discriminant analysis and cluster analysis. The data provided can be used by researchers and scientists in the differentiation of fruits based on major and minor mineral elements.

Fulltext Treatment of rubber wastewater using zinc sulphate as coagulants-data collection on removal efficiency for physicochemical and heavy metal parameters

Data Brief, 2021 Feb;34:106685.

PMID: 33409347 DOI: 10.1016/j.dib.2020.106685

This article provides data regarding the performance of zinc sulphate as a coagulant for treating rubber industry wastewater. The effect of four factors on removal efficiency of nine parameters is investigated, namely: pH, mixing speed, dosage of coagulant (zinc sulphate) and retention time. Response surface methodology was used to investigate the effect of selected variables. The data obtained from face centered composite design (FCCD) were analyzed by using analysis of variance (ANOVA) and regression model to find the optimum operating conditions for the selected factors.

PMID: 31011604 DOI: 10.1016/j.dib.2019.103894

This article presents data relating to the changes in absorbance of glucose during the acid hydrolysis of sugarcane bagasse using sulphuric acid. This dataset also contains the moisture content, volatile matter, and fixed carbon of the sugarcane bagasse. The results of the analysis of variance (ANOVA) and the interaction plots between reaction time, temperature, and ratio are also presented. The data revealed that absorbance of glucose is increasing by increasing the temperature and time. Moreover, the best ratio for the highest absorbance of glucose was achieved at 1:20.
