Med J Malaysia, 2023 Nov;78(6):711-716.

INTRODUCTION: In gynaecology, laparoscopy is the choice of treatment for a lot of procedures as it is considered safe and effective. However, laparoscopic surgery requires skills that are different from those required for open surgery. In order to acquire the skills, a surgeon needs specific training. The aim of this study was to validate the AR Gynae endotrainer, a new mobile laparoscopic simulator, as a comparable box trainer for gynaecology laparoscopic training, comparing it with the well-established Karl Storz SZABO-BERCISACKIER laparoscopic trainer.

MATERIALS AND METHODS: A randomised prospective crossover study was designed to compare the AR Gynae endotrainer versus Karl Storz SZABO-BERCI-SACKIER laparoscopic trainer as a tool for training gynaecology laparoscopic skills. Participants were assigned to perform two specially designed tasks used for laparoscopic training using both endotrainers. All subjects evaluated both simulators concerning their performance by the use of a questionnaire comparing: design, ports placement, visibility, ergonomics, triangulation of movement, fulcrum effect, depth perception, ambidexterity, resources for training, and resources for teaching. The overall score was defined as the median value obtained. The ability and time taken for participants to complete the tasks using both endotrainers were also compared. A total of 26 participants were enrolled in this study, including 13 Masters's students from the Department of Obstetrics & Gynaecology and 13 Masters's students from the Department of Surgery, Hospital Universiti Sains Malaysia (HUSM), Kelantan, Malaysia.

RESULTS: A better performance was observed with AR Gynae as compared to Karl Storz endotrainer in five out of ten items evaluated in the questionnaire. Additionally, the overall score of AR Gynae endotrainer (median of 3.98) was comparable to that of Karl Storz endotrainer (median of 3.91) with p=0.519. For the items design and resources for teaching, the evaluation for AR Gynae endotrainer was significantly higher with p-values of 0.003 and 0.032, respectively. All participants were able to complete both tasks using both endotrainers. The time taken to complete both tasks was comparable on both endotrainers. Also, the AR Gynae endotrainer was cheaper.

CONCLUSIONS: The AR Gynae endotrainer was found to be a convenient and cost-effective laparoscopic simulator for gynaecology laparoscopic training and was comparable to the established Karl Storz SZABO-BERCI-SACKIER laparoscopic trainer.

PMID: 26358022 MyJurnal

BACKGROUND: Preoperative anxiety is a significant problem worldwide that may affect patients' surgical outcome. By using a simple and reliable tool such as the Amsterdam Preoperative Anxiety and Information Scale (APAIS), anaesthesiologists would be able to assess preoperative anxiety adequately and accurately.

OBJECTIVE: The purpose of this study was to develop and validate the Malay version of APAIS (Malay-APAIS), and assess the factors associated with higher anxiety scores.

METHODS: The authors performed forward and backward translation of APAIS into Malay and then tested on 200 patients in the anaesthetic clinic of University Malaya Medical Centre. Psychometric analysis was performed with factor analysis, internal consistency and correlation with Spielberger's State-Trait Anxiety Inventory (STAI-state).

RESULTS: A good correlation was shown with STAI-state (r = 0.59). Anxiety and need for information both emerged with high internal consistency (Cronbach's alpha 0.93 and 0.90 respectively). Female gender, surgery with a higher risk and need for information were found to be associated with higher anxiety scores. On the other hand, previous experience with surgery had lower need for information.

CONCLUSION: The Malay-APAIS is a valid and reliable tool for the assessment of patients' preoperative anxiety and their need for information. By understanding and measuring patient's concerns objectively, the perioperative management will improve to a much higher standard of care.

PMID: 12014766

Vaginal hysterectomy for the large uterus is seldom performed in Malaysia. The traditional operation is abdominal hysterectomy. This is a personal series of vaginal hysterectomies for enlarged uterus of more than 12 weeks size (>280g) carried out in a private hospital between 1/1/97 to 30/9/2000. A total of 40 cases were done with the weights of the uterus ranging from 290g to 790g. The mean weight of the uterus was 434g. The average operating time was 92.1 min. The complications were minimal with 2 cases of blood transfusion for intra-operative hemorrhage, 1 case of fever and 1 case of bladder perforation. This series demonstrates feasibility and safety of the operation. The excellent recovery due to the absence of an abdominal scar should be a strong incentive for specialists to learn the skill.

PMID: 30647224

Immune Thrombocytopenia Purpura (ITP) secondary to vaccinations is rare, especially after autologous hematopoietic stem cell transplantation (HSCT). A 31-yearold female received autologous HSCT for relapsed Hodgkin Disease, with platelet engraftment at Day+14. One week after receiving second scheduled vaccinations, she developed severe thrombocytopenia (3x109/L) associated with pharyngeal hematoma. Bone marrow (BM) examinations were consistent with ITP, possibly secondary to Influenza vaccine. Platelet increment was poor despite high dose corticosteroids, intravenous immunoglobulin (IVIG), Danazol and Eltrombopag. A repeated BM biopsy was in agreement with ITP. Re-treatment with tapering doses of prednisolone resulted in stable platelet counts at 120x109/L a year later.

PMID: 17682565 MyJurnal

Allogeneic stem cell transplantation is a treatment option for malignant and non-malignant disorders in children. For children with no HLA-matched sibling or related stem cell donors, there is the option of unrelated cord blood donors. At the University of Malaya Medical Centre (UMMC) in Kuala Lumpur, the first unrelated cord blood transplantation (CBT) was performed in October 1997. All unrelated CBT performed in UMMC relied on cord blood units imported from overseas. DNA typing with variable number of tandem repeat (VNTR) loci was done to qualitatively evaluate engraftment in 15 unrelated CBT. In all the fifteen cases that were evaluated, molecular evidence of engraftment or non-engraftment correlated with the clinical findings.

PMID: 10972002

A provisional clinical diagnosis of exanthem subitum was made in six febrile infants seen in the Paediatric Unit of Assunta Hospital, Petaling Jaya, Malaysia with uvulo-palatoglossal junctional ulcers prior to the eruption of maculopapular rash. On follow-up, all six infants developed maculopapular rash with the subsidence of fever at the end of the fourth febrile day. Human herpesvirus 6 was isolated from the peripheral blood mononuclear cells during the acute phase of the illness and HHV 6 specific genome was also detected in these cells by nested polymerase chain reaction. All the six infants showed seroconversion for both specific IgG and IgM to the isolated virus. This study suggests that the presence of uvulo-palatoglossal junctional ulcers could be a useful early clinical sign of exanthem subitum due to human herpesvirus 6.

PMID: 12733195

OBJECTIVE: The objective of this survey was to obtain a self-reported assessment of the use of Information and Communication Technology (ICT) by medical students at the International Medical University, Malaysia.
MATERIALS AND METHODS: Students' perceived skills and extent of usage of ICT were evaluated using a questionnaire. Chi-square analysis were performed to ascertain the association between variables. Further statistical testing using Chi-square test for trend was done when one of the variables was ordered, and Spearman rank correlation when both variables were ordered.
RESULTS: Overall, (98%) of students responded to the questionnaire. Twenty seven students (5.7%) did not use a computer either in the university or at home. Most students surveyed reported adequate skills at word processing (55%), e-mailing (78%) and surfing the internet (67%).
CONCLUSION: The results suggests that in order to increase the level of computer literacy among medical students, positive steps would need to be taken, for example the formal inclusion of ICT instruction in the teaching of undergraduate medicine. This will enhance medical students' ability to acquire, appraise, and use information in order to solve clinical and other problems quickly and efficiently in the course of their studies, and more importantly when they graduate.

Fulltext Utilization of beta blockers post-myocardial infarction

PMID: 23466769 MyJurnal

Beta blockers provide both morbidity and mortality benefits for post-myocardial infarction (MI) patients. Despite this, beta blockers are still often underused or used at suboptimal dosages. This was a retrospective observational study with the objectives of estimating the proportion of post-MI patients who are receiving beta-blocker therapy in University Malaya Medical Centre (UMMC), assessing the number of them receiving beta blockers at optimal dosages and determining the factors associated with beta-blocker prescribing post-MI. Of 315 patient case notes reviewed, 77.5% were prescribed beta blockers. However, dosages were optimized in only 39.3% of patients. Reasons for not optimizing the dosages were typically not due to the presence of contraindications to beta blockers. Elderly (> 65 years old), ejection fraction (EF) < 40%, a history of cerebrovascular accident (CVA) or mild asthma, use of calcium channel blocker (CCB), digoxin or anti-asthmatic agents were all significantly associated with a reduced rate of beta-blocker prescribing post-MI. More effort should be placed in improving its use in specific patient populations. Initiatives to optimize the dosage of beta blockers to recommended dosages that matched those in clinical trials with proven mortality benefits will also need to be intensified.

Fulltext Utilisation of specialist medical manpower in Malaysia

Wong SL, Mohan AJ, Suleiman AB

Med J Malaysia, 1998 Sep;53(3):245-50.

PMID: 10968161

One hundred and twenty specialists from the Ministry of Health, the Universities and the private sector provided information on 4,802 patients seen over a total of two hundred and forty working days. This information was used to classify the patients into four categories based on a disease complexity classification. Each specialist's perception on the appropriateness of utilisation of his expertise was obtained. Complex cases requiring specialist expertise in management made up 69.8%, 73.5% and 19.1% of the cases of the Ministry of Health, University and private sector specialists respectively. Underutilisation was most marked with paediatricians and obstetricians in the private sector. The Specialist Register, the Programme for Accreditation of Hospitals and a National Health Financing Plan can be used to influence positively the case-mix of specialists.

PMID: 15190634

Between 1st January 1999 and 31st December 2000, 452 foreign nationals were treated at the Department of Ophthalmology, Hospital Sultanah Aminah, Johor Bahru. Eighty-five percent were male. The peak age range was from 21 to 30 years old. The patients were predominantly Indonesians (61%). A history of trauma was present in 63% of patients. Eight percent of eyes had severe visual impairment. Six patients (1.3%) were blind by WHO standards. Traumatic eye conditions, inflammatory/allergic eye conditions and degenerative eye conditions comprised 66%, 13% and 10% respectively of ocular pathology seen. The commonest ocular findings were corneal foreign body, corneal abrasion and subconjunctival haemorrhage.

PMID: 32467549

Uterine artery pseudoaneurysm (UAP) is a rare acquired vascular malformation associated with vaginal bleeding or intraabdominal haemorrhage occurring after pelvic surgery. Pseudoaneurysm may present with delayed, severe haemorrhage after a seemingly uncomplicated initial postoperative period. Treatment is therefore necessary to prevent further complications. We describe here a case of a 32-year-old mother, who presented with abdominal pain and intraabdominal bleeding, 20 days after Caesarean Section. Computerised Tomography (CT) scan showed the presence of haemoperitoneum, suggestive of pseudoaneurysm at the right cervical artery which was successfully managed with emergency angiographic embolisation.

PMID: 14556339

A case of spontaneous rupture of uterine artery in the second trimester of pregnancy is described. Haemorrhage from rupture of uterine artery during pregnancy was discovered at laparotomy. This was an unusual but serious complication of pregnancy. This condition is extremely rare and one must consider it in cases of incomprehensible abdominal pain with or without haemodynamic collapse. A review of the literature revealed only four similar cases so far. This pregnancy continued till 37 weeks pregnancy and had a spontaneous vaginal delivery. Immediate institution of effective resuscitative measures and early surgical intervention were essential to both foetal and maternal survival.

Uterine arteriovenous malformation - Possible association to uterine fibroids?

Gan F, Vikneswaran V, Yu KK

Med J Malaysia, 2021 03;76(2):273-274.

PMID: 33742646

A 32-year-old, gravida 2 para 0+1, was managed in Selayang Hospital, Selangor for uterine fibroids in pregnancy and placenta previa major. The lady went into preterm labour at 33 weeks, requiring emergency Caesarean section. Intraoperatively, we found a thinned-out bulge between the intramural uterine fibroids at the posterior uterine wall, which then perforated and was repaired. Persistent bleeding post operatively led to relaparotomy and hysterectomy. Histology of the uterus reported arteriovenous malformation (AVM). We postulate the possibility of these lesions coexisting with uterine fibroids. Screening for uterine AVMs in patients with fibroids may lead to early detection with option of embolization; deferring the need for hysterectomy.

PMID: 26032536 MyJurnal

There is little information about the willingness of medical students to participate in Facebook for education. I analyzed my interactions with students for the past 14 months to estimate the quantity of student interaction. A Facebook Group was created. Students friend requests were accepted, but "friending" was never solicited. Questions were created around a clinical situation and posted. Forty questions were posted. 5/40 questions were about physics/chemistry. 24 questions focused on basic medical sciences. 11 questions were primarily about clinical medicine. In fourteen months, 533/810 (66%) college students joined the Group. In all, 163/533 students (30%) responded at least once. Half of all responses were comments; the rest were clicks on the "like" button. The average number of responses was 9.5 unique students/question. If participation is voluntary, and targeted students are large in number, one can expect about 66% of students to become members of a site, and about 30% of these to interact. For any given question posted on the site, about 2% of members will respond, regardless of the nature of question: clinically oriented or basic.

Fulltext Usefulness of cytological specimens from bronchial brushings and bronchial washings in addition to endobronchial biopsies during bronchoscopy for lung cancer: 3 years data from a chest clinic in a general hospital

Fauzi AR, Balakrishnan L, Rathor MY

Med J Malaysia, 2003 Dec;58(5):729-34.

PMID: 15190660

A retrospective review of all bronchoscopy cases for investigation of lung cancer between January 1997 and December 1999 was done. The cases were included if endobronchial mass was visible (Group A) or when there was an abnormal mucosa and/or bronchial narrowing in the absence of a mass (Group B). All patients in Group A (n = 177) underwent endobronchial biopsy (EB) bronchial brushings (BB) and bronchial washings (BW). All cases in Group B underwent transbronchial biopsy (TBB), BB and BW. Only a small increase in the positive results for cancer was seen when cytology specimens (BB and BW) were added to EB (85.3% vs 88.1%, McNemar's P = 0.06) in Group A but there was a significant increase in Group B (37.3% vs 54.2%. McNemar's, P = 0.001). Therefore although cytology specimens did not significantly add to overall yield of positive results when endobronchial lesions were visible, when mass lesions were not visible, cytology specimens increased the yield by 16.9%.
