Introduction: Hamstring tendon (HT) and bone patellar tendon bone (BPTB) are the commonly used
autograft in an anterior cruciate ligament reconstruction surgery. The BPTB is said to have more incidence of
anterior knee pain compared to HT. The study aimed to compare the severity of knee pain during Islamic
prayer kneeling. Methods: A cross sectional cohort analysis of patients undergoing ACL reconstruction surgery
using BPTB with HT autografts was conducted to determine differences in postoperative pain while kneeling
and ability to pray in normal position. Kneeling during prayer and the ability to sit while performing prayer
were assessed at 3rd, 4th, 5th and 6th month. Results: There were no significant differences in mean pain score
while kneeling at 3rd, 4th, 5th and 6th month. The mean difference of patient’s ability to perform normal
prayers for BPTB (3.56+1.16) and HT (3.30+1.05) was found insignificant. The average number of patients in
both groups was able to pray between 3 to 4 months post operatively as full range of motion of knee is
allowed within this period. Total 49 patients (BPTB 23, HT 26) out of 60 were able to pray normally within 4
months post-operation. Mostly delayed due to anterior knee pain. Conclusion: There is no different in term of
knee pain during kneeling while performing Islamic prayer between those who had their ACL reconstructed
either using BPTB or HT autograft.

The WOMAC questionnaire is used extensively in the assessment of knee osteoarthritis but not as an indicator of total knee arthroplasty (TKA). We aimed to assess if the WOMAC score can be used as an assessment tool to indicate TKA in primary knee osteoarthritis. Materials and Methods:Patients with primary knee osteoarthritis Kellgren and Lawrence grades 3 or 4 were assessed separately by either one of two arthroplasty surgeons for indications to undergo TKA and evaluated using the WOMAC score. Patients who had received any form of intra-articular knee injection within six months before assessment were excluded. Patients were divided into two groups; indicated for TKA, and for non-surgical treatment. The mean WOMAC score of patients from both groups was compared using Independent t-test. The accuracy at different cut-off points in the score indicated for TKA was determined using the receiver operating characteristic (ROC) curve plotted on sensitivity and 1-specificity graph. Results:The study included 74 patients with a mean age of 62.5 years (SD=8.26). There was a significant difference in the total WOMAC score (p

Irreducible dislocation of the interphalangeal joint (IPJ) big toe is a rare injury Hitori et al. (2006) . We report a case of the right big toe IPJ dislocation following a trauma. The problem was diagnosed and managed at other medical centers with standard treatment of closed manual reduction and splint. The right big toe was splinted accordingly and the patient was referred to our orthopedic outpatient clinic. At the clinic, a repeat plain radiograph was ordered due to high suspicion of the irreducible IPJ.

Chondrosarcoma of the mandible: a case report

Saini R, Abd Razak NH, Ab Rahman S, Samsudin AR

J Can Dent Assoc, 2007 Mar;73(2):175-8.
PMID: 17355810

Chondrosarcomas are malignant tumours of cartilaginous origin. They range from a well-differentiated growth resembling a benign cartilage tumour to a high-grade malignancy with aggressive local behaviour and the potential to metastasize. Only 5% to 10% of chondrosarcomas are known to occur in the head and neck region. A case of chondrosarcoma of the anterior region of the mandible is presented, along with a review of the relevant literature.
Fulltext HLA-Haploidentical Family Donors: The New Promise for Childhood Acute Lymphoblastic Leukaemia?

Allogeneic haematopoietic stem cell transplantation (HSCT) is indicated in children with high-risk, relapsed or refractory acute lymphoblastic leukaemia (ALL). HLA-matched grafts from cord blood and stem cell repositories have allowed patients without suitable sibling donors to undergo HSCT. However, challenges in procuring matched unrelated donor (MUD) grafts due to high cost, ethnic disparity and time constraints have led to the exponential rise in the use of stem cells from human leukocyte antigen (HLA)-haploidentical family donors. Whilst HLA-haploidentical HSCT (hHSCT) performed in adult patients with acute leukaemia has produced outcomes similar to MUD transplants, experience in children is limited. Over the last 5 years, more data have emerged on hHSCT in the childhood ALL setting, allowing comparisons with matched donor transplants. The feasibility of hHSCT using adult family donors in childhood ALL may also address the ethical issues related to selection of minor siblings in matched sibling donor transplants. Here, we review hHSCT in paediatric recipients with ALL and highlight the emergence of hHSCT as a promising therapeutic option for patients lacking a suitable matched donor. Recent issues related to conditioning regimens, donor selection and graft-vs.-host disease prophylaxis are discussed. We also identify areas for future research to address transplant-related complications and improve post-transplant disease-free survival.
Fulltext Manipulating the Gut Microbiome as a Therapeutic Strategy to Mitigate Late Effects in Childhood Cancer Survivors

Recent studies have identified causal links between altered gut microbiome, chronic inflammation, and inflammation-driven conditions such as diabetes and cardiovascular disease. Childhood cancer survivors (CCS) show late effects of therapy in the form of inflammaging-related disorders as well as microbial dysbiosis, supporting a hypothesis that the conditions are interconnected. Given the susceptibility of the gut microbiome to alteration, a number of therapeutic interventions have been investigated for the treatment of inflammatory conditions, though not within the context of cancer survivorship in children and adolescents. Here, we evaluate the potential for these interventions, which include probiotic supplementation, prebiotics/fiber-rich diet, exercise, and fecal microbiota transplantation for prevention and treatment of cancer treatment-related microbial dysbiosis in survivors. We also make recommendations to improve adherence and encourage long-term lifestyle changes for maintenance of healthy gut microbiome in CCS as a potential strategy to mitigate treatment-related late effects.

J Periodontal Implant Sci, 2013 Aug;43(4):153-9.
PMID: 24040567 DOI: 10.5051/jpis.2013.43.4.153

The level of the implant above the marginal bone and flap design have an effect on the bone resorption during the healing period. The aim of this study is to detect the relationship between the level of the implant at the implant placement and the bone level at the healing period in the mesial and distal side of implants placed with flapless (FL) and full-thickness flap (FT) methods.

Nandakumal G, Ismail F, Mohamad NF, Lott PW, Chew KS, Ab Rahman S, et al.

J Pediatr Hematol Oncol, 2021 04 01;43(3):101-103.
PMID: 33560075 DOI: 10.1097/MPH.0000000000002077

Hemolacria is a rare condition that causes a person to produce tears that are partially composed of blood. It can be a presenting feature of certain ocular and systemic conditions. Here, the authors describe an interesting case of a 12-year-old boy with an underlying beta-thalassemia trait, who presented with a 2-day history of bilateral blood-stained tears, and an episode of epistaxis. Ocular examination was normal, and syringing showed no nasolacrimal duct blockage. Systemic examination was unremarkable. Laboratory investigations confirmed type 2 von Willebrand disease. Management of hemolacria remains a clinical challenge given the rare occurrence of the disease. In this case report, the authors discuss the differential diagnosis and management approach to hemolacria.
Fulltext Intraoperative Patella Dimension Measurement in Asian Female Patients and Its Relevance in Patellar Resurfacing in TKA

Ab Rahman S, Ahmed Shokri A, Ahmad MR, Ismail AF, Termizi NS

Adv Orthop, 2020;2020:4539792.
PMID: 32411483 DOI: 10.1155/2020/4539792

Background: Implants used for total knee arthroplasty (TKA) in Asian patients are mostly produced based on anthropometry of the Western population, thus causing problem with patella sizing, especially in Asian females where the patellae are regarded to be smaller. This study is to define intraoperative patella dimensions in our female populations and compare them with current prosthetic systems available at our institution.
Methods: This is a cross-sectional study involving 156 TKA female patients with normal patellae. The patella height, width, thickness, medial and lateral articular facets' width and thickness, and the dome position were measured. The smallest implant size from 3 manufacturers was compared to the data obtained. Analysis using descriptive statistics was used to get the mean and median of anatomical patella dimensions, whereas the independent T test and one-way ANOVA test were used to compare the Malaysian female's patella dimensions with various implant sizes.
Results: The articular surface of the patella was found to have an oval shape with a width-height ratio of 1.31. The mean (SD) patella thickness, width, and height were 20.7 (1.85) mm, 40.7 (3.79) mm, and 31.3 (2.81) mm, respectively. Only 17.9% fit for smallest implant size from all 3 manufacturers. The oval-shape implant was suitable in 53.8% patients based on their width-height ratio. The dome position is 2.2 mm medial to centre.
Conclusion: These female patients have thinner and smaller patella, which are generally unable to accommodate patellar components based on the Caucasian database. Therefore, orthopaedic implant manufacturers should consider optimizing the thicknesses as well as widths of their patellar prostheses.

Singapore Med J, 2016 Mar;57(3):138-43.
PMID: 26996450 DOI: 10.11622/smedj.2016055

INTRODUCTION: Physiotherapy is an important part of rehabilitation following arthroplasty, but the impact of preoperative physiotherapy on functional outcomes is still being studied. This randomised controlled trial evaluated the effect of preoperative physiotherapy on the short-term functional outcomes of primary total knee arthroplasty (TKA).
METHODS: 50 patients with primary knee osteoarthritis who underwent unilateral primary TKA were randomised into two groups: the physiotherapy group (n = 24), whose patients performed physical exercises for six weeks immediately prior to surgery, and the nonphysiotherapy group (n = 26). All patients went through a similar physiotherapy regime in the postoperative rehabilitation period. Functional outcome assessment using the algofunctional Knee Injury and Osteoarthritis Outcome Score (KOOS) scale and range of motion (ROM) evaluation was performed preoperatively, and postoperatively at six weeks and three months.
RESULTS: Both groups showed a significant difference in all algofunctional KOOS subscales (p < 0.001). The mean score difference at six weeks and three months was not significant in the sports and recreational activities subscale for both groups (p > 0.05). Significant differences were observed in the time-versus-treatment analysis between groups for the symptoms (p = 0.003) and activities of daily living (p = 0.025) subscales. No significant difference in ROM was found when comparing preoperative measurements and those at three months following surgery, as well as in time-versus-treatment analysis (p = 0.928).
CONCLUSION: Six-week preoperative physiotherapy showed no significant impact on short-term functional outcomes (KOOS subscales) and ROM of the knee following primary TKA.

Fulltext Case Report: Severe Hyponatremia in Infants With Urinary Tract Infection

Abu Bakar K, Jalaludin MY, Zainal N, Woon SL, Mohd Zikre N, Samingan N, et al.

Introduction: Many reports on investigations and treatments in UTI, however little, have been mentioned with regard to electrolyte abnormalities. Secondary pseudohypoaldosteronism (PHA) in UTI, though less common, is a known association. Features include hyponatremia and concomitant hyperkalemia. Objectives: We aim to highlight these uncommon sequelae in UTI to avoid incorrect diagnosis and unnecessary investigations. Study Design: Clinical data of patients admitted and referred to a pediatric nephrologist at the University Malaya Medical Center between May 2019 and October 2020 were collated and elaborated. Results and Discussion: We report three infants with hyponatremia and hyperkalemia during UTI episodes. Two infants were known to have posterior urethral valve (PUV) before the onset of UTI and one infant had UTI, which led to investigations confirming the diagnosis of bladder vaginal fistula. The electrolyte derangements were temporary and resolved within 48 to 72 h of treatment with intravenous fluid and appropriate antibiotic therapy. Out of three, only one had a hormonal study, which confirms PHA. Reduced aldosterone activity could be due to absolute reduction in aldosterone titer or lack of aldosterone responsiveness at tubular (other tissues) level. In the latter, aldosterone titer is elevated. The infant in our cohort who had hormonal evaluation had the mentioned electrolyte abnormalities with a markedly elevated aldosterone titer. This demonstrated defective action of the hormone at the level of mineralocorticoid receptor. Although the remaining two infants had no confirmatory hormonal study, all of them recovered within 48 h of hospital admission, after receiving appropriate management for the primary problem, which was UTI. We observed a slower recovery of hyponatremia in relation to hyperkalemia, but none of these infants required salt replacement upon discharge. Conclusion: Infants with severe UTI and deranged electrolytes should be screened for structural abnormality and vice versa. Not all infants require hormonal screening, but those who required prolonged salt replacement or showed involvement of other systems warrant further evaluation.

This study sought to determine the prevalence of pathogenic and non-pathogenic bacteria in the oral cavities of children with cancer. There were 68 paediatric patients with cancer who were included in this study. Oral swab samples from the dorsum of tongues and mouth floors of these patients were subjected to culture, staining, and molecular methods to detect the bacteria. The overall prevalence of gram-positive and gram-negative bacteria was 79.4% (54/68; 95% CI = 68.4 - 87.3) and 25% (17/68; 95% CI = 16.2 - 36.4), respectively. Streptococcus salivarius and Streptococcus parasanguinis were the predominant pathogenic grampositive bacteria, while Neisseria subflava and Neisseria perflava were the most common pathogenic gram-negative bacteria. The results revealed that the number of bacteria isolates recovered in patients receiving cancer treatment was higher (55.9%) than those who had not received treatment (16.2%). Therefore, more isolated pathogenic bacteria were observed post-therapy (54.4%). Pathogenic organisms can have significant implications on patient health. Awareness of the types of bacteria inhabiting the oral cavity is essential to predict and prevent dental problems, and their associated systemic complications. Findings on the diversity of oral microflora can also provide a better understanding of the aetiology of oral diseases in paediatric patients receiving cancer treatment.

Diabetes mellitus is known to compromise the various aspects of homeostasis, including the immune response and the composition of oral microflora. One of the oral manifestations of diabetes mellitus is tooth loss and the survival rate of dental implants chosen as a treatment modality for its rehabilitation is controversial. The current study aims to evaluate and compare the failure rate of dental implants between well-controlled diabetic and healthy patients. A retrospective study of case-control design was conceptualized with 121 well-controlled diabetic and 136 healthy individuals. Records of subjects who had undergone oral rehabilitation with dental implants between the periods of January 2013 to January 2016 were retrieved. Post-operative evaluation was carried out for all patients for about three years to assess the immediate and long-term success of the procedure. From a total of 742 dental implants, 377 were placed in well-controlled diabetic patients (case group) and 365 in healthy subjects (control group). A comparable (9.81%), but non-significant (p = 0.422) failure rate was found in the case group in comparison to the control group (9.04%). A non-significant (p = 0.392) raised number (4.98%) of failure cases were reported among females in comparison to males (4.44%). In respect to arch, the mandibular posterior region was reported as the highest failure cases (3.09%; p = 0.411), with 2.29% of cases reported in the mandibular anterior (p = 0.430) and maxillary posterior (p = 0.983) each. The maxillary anterior region was found to have the least number (1.75%; p = 0.999) of failure cases. More (4.98%; p = 0.361) cases were reported to fail during the functional loading stage in contrast to osseointegration (4.44%; p = 0.365). A well-controlled diabetic status does not impose any additional risk for individuals undergoing dental implant therapy.
Haematopoietic stem cell transplantation for inborn errors of immunity: 25-year experience from University of Malaya Medical Centre, Malaysia

Ariffin H, Ab Rahman S, Jawin V, Foo JC, Amram NF, Mahmood NM, et al.

J Paediatr Child Health, 2020 Mar;56(3):379-383.
PMID: 31479560 DOI: 10.1111/jpc.14621

AIM: Inborn errors of immunity (IEI) comprise a heterogeneous group of disorders of the immune system, most of which are curable by haematopoietic stem cell transplantation (HSCT). We present a 25-year audit of HSCT for IEI at a tertiary-level academic hospital in Malaysia.
METHODS: Review of medical records of all cases of IEI who underwent HSCT between January 1993 and December 2018 at our centre. Diagnoses, complications, HSCT protocols and outcome data were studied.
RESULTS: There were 20 patients (19 boys) with a median age at diagnosis of 11 months (range: 2 months to 12 years). Eleven of 19 (58%) had malnutrition at presentation. Donor sources were variable: 13 (65%) matched sibling donor (MSD), 4 (20%) human leukocyte antigen-haploidentical donor (HD) and 3 (15%) matched unrelated donor (MUD). Conditioning regimens were physician-dependent and adapted to each patient's clinical status. Grades III-IV acute graft-versus-host disease occurred in two of three cases who received MUD grafts, 50% in those who received HD, and 8% in the MSD group. Transplant-related mortality at day +100 was 5%. With a median follow-up of 7.5 years, 18 (90%) patients are alive and free of infections.
CONCLUSION: Outcome of HSCT for IEI in our centre is comparable with international reports. HSCT results using HD and MUD grafts are also good despite challenges from acute graft-versus-host disease, providing a feasible alternative for patients without matched donors.
