    INTRODUCTION: Procalcitonin (PCT) has recently emerged as a marker for diagnosing infection. This study aimed to compare the performance of PCT and other infection markers in diagnosing infected diabetic foot ulcer (IDFU).

    MATERIALS AND METHODS: A total of 128 diabetic patients with foot ulcers were recruited and divided into two groups, consisting of 73 patients in the IDFU group and 55 in the non-infected diabetic foot ulcer (NIDFU). The severity of infection in IDFU patients was graded based on the Infectious Disease Society of America-International Working Group on the Diabetic Foot classification. Blood samples from all the patients were collected for measurement of PCT, high sensitivity C-reactive protein (hs-CRP) and white cell count (WBC). The area under the receiver operating curves (AUC) were then constructed and analysed.

    RESULTS: PCT, hs-CRP and WBC levels were significantly higher in the IDFU group compared to NIDFU with hs-CRP demonstrated the highest AUC (0.91; p <0.001) followed by PCT (0.814; p < 0.001) and lastly WBC (0.775; p < 0.001). The best cut off value, sensitivity and specificity for the presence of infection in diabetic foot, were 3.47 mg/dL, 80% and 89% for hs-CRP, 0.11 ng/ml, 70% and 87% for PCT and 11.8x109/L, 60% and 90% for WBC. All the infection markers showed significant positive correlations with infection severity of DFU.

    CONCLUSION: This study showed that hs-CRP is a more sensitive marker for diagnosing IDFU. Although PCT is useful in differentiating IDFU from NIDFU, the use of PCT is not necessary as it adds little value to the current practice.

    BACKGROUND: The placenta is a most interesting but unfortunately often ignored and misunderstood organ. Placental abnormalities, therefore, can be an "early warning system" for fetal problems. A complete prenatal sonographic examination of the placenta is an essential component as its abnormalities can have a direct effect on fetal or maternal outcomes, obstetrical management and future fertility.

    OBJECTIVE: To determine whether any association exists between the finding of an increased thickness of placenta, abnormal placenta shape, placental calcification, placental lake and abnormal cord insertion site at 20-22 and 30-32 weeks gestation with an increased risk of uteroplacental complications or a poor pregnancy outcome.

    METHODOLOGY: A real-time ultrasound was used at the time of detail scan (at 20-22 weeks gestation) and at 30-32 weeks gestation to look for placenta appearance, fetal growth and anomaly. The main outcome measures were risk of hypertension disease in pregnancy, fetal growth restriction and poor fetal outcomes such as low Apgar score and low cord pH.

    RESULT: The majority of the participants were Malay (77.9%). Abnormal placenta found at both gestations were placental lakes and thickness, and only one case had marginal cord insertion. Approximately 6% of the cases were confirmed placenta previa. No abnormal shape or abnormal calcification found at both gestations. About 10% patient developed hypertensive disease in pregnancy, 15% of the fetus was found to have growth restriction and another 16% have low umbilical cord pH. Majority of them delivered at term (90%) and via vaginal delivery (81%). There was no significance between presence of abnormal placental lake and thickness at both gestations with the maternal and fetal outcome.

    CONCLUSION: Presence of abnormal placental thickness and lakes at 30-32 weeks scan associated with maternal hypertensive disease, fetal growth restriction and low umbilical cord pH, however these were not statistically significant.

    The incidence of wrist tuberculosis is rare. Clinical features and radiographs are not conclusive in the beginning, happen to delay the achievement of the diagnosis, and thus result in poor treatment. We present a case report of wrist tuberculosis that had delayed diagnosis. Hence, the initiation of antituberculous treatment was delayed, as the initial investigations were not conclusive of tuberculous infection. The patient was treated surgically multiple times before tuberculosis was diagnosed. Antituberculous chemotherapy was started for the patient for one year until she became afebrile and infective markers returned to normal. However, the patient developed left wrist stiffness due to arthrofibrosis and bony destruction of the wrist joint.

    The Internet of Things (IoT) plays an important role in various healthcare applications. Radio Frequency IDentification (RFID) is widely used as a leading identification technology in a variety of IoT-health applications. In 2020, the number of cases of novel Corona Virus Disease 2019 ( n COVID-19) was increased rapidly throughout the world. Herein, IoT-Health enables the more convenient ways to access remotely and efficiently the medical services for the patients, also provides health monitoring by the doctors, physicians, and nurses over the Internet. However, security and privacy are considered key concerns in RFID-based IoT-health systems due to wireless communication over the channel. There could be huge risks of leakage of the patient's sensitive information, medical data, privacy of the patients, and so forth. To overcome these shortcomings, we have put forward a secure and reliable RFID authentication protocol using Digital Schnorr Cryptosystem for IoT-Health in COVID-19 patients care named S R 2 AP-DSC. Compared with the similar existing protocols, the security analysis followed by the performance evaluation of our proposed protocol demonstrates the minimal computation overheads and also provides resistance to various well-known security attacks. The AVISPA and Scyther simulation results confirm that the proposed protocol is safe under active and passive attacks. The overall analysis shows that the S R 2 AP-DSC is relatively superior to the other similar existing protocols.

    A bent intramedullary (IM) nail becomes challenging and technically demanding to the orthopaedic surgeon for nail extraction. A broken nail can be easily removed through the fracture site. However, a bent nail has to be broken before it can be removed. Several studies and case reports outline the strategies and techniques for removing a bent IM nail. However, there is a paucity of guidelines and standard protocol describing the best and inexpensive strategy. We report a case where two years following surgery for intramedullary nailing of the right femur, the IM mail was bent following secondary trauma. We used a technique based on the principles of an ability to fully cut the nail and extract it in two pieces by using a Jumbo cutter which is available in the orthopaedic armamentarium. This technique is simple yet economical, with the likelihood of causing less soft tissue damage and thermal necrosis.

    INTRODUCTION: Charcot arthropathy is a condition which is progressive, non-infectious, destructive and debilitating that commonly affect foot and ankle. This systematic review is to evaluate the occurrence of common outcomes associated with each intervention of Charcot neuroarthropathy in midfoot.

    MATERIALS AND METHODS: A systematic review on literatures that were published from Jan 2010 to Jan 2020 were collected, reviewed and selected regarding the surgical treatment procedures of Charcot neuroarthropathy in midfoot.

    RESULTS: The initial search yielded 231 reports and after exclusion, nine out of the total studies were included in the outcome analysis for review. These were studies that included data concerning surgical reconstruction of Charcot arthropathy in the midfoot.

    CONCLUSION: It is suggested that soft tissue preparation and usage of combination of implants thus reduce the risk of infection as well as increase rigidity of construct, respectively. These factors will aid to improve outcome of midfoot Charcot arthropathy reconstruction.

    Hypertrophic scar formation is a major clinical problem that results in both cosmetic issues and functional loss. The management of a hypertrophic scar varies according to the severity of the sequelae from the scar. We describe a method of treatment in a patient who had a history of multiple debridements due to snake bite resulting in severe contracture of the fourth toe complicated with a hypertrophic scar.

    The injection of a local anesthetic in combination with a corticosteroid is an accepted choice in the treatment of plantar fasciitis with recalcitrant heel pain. When the injection is performed properly, post-injection infection is extremely rare. We are reporting a rare case of chronic calcaneal osteomyelitis that developed secondary to a local corticosteroid injection. A 56-year-old lady diagnosed with right plantar fasciitis presented with a 6-month history of pain and a persistent sinus with serous discharge of her right heel following a local infiltration of a corticosteroid. A Magnetic Resonance Imaging demonstrated right calcaneal osteomyelitis with intramuscular abscess. Surgical drainage and debridement were done, followed by antibiotic therapy. A recurrence of infection was not detected throughout the duration of follow-up. It is suggested that a plantar heel injection be done in a more controlled environment, such as in operating theatre, to reduce the risk of infection and to avoid injecting a steroid as compared to platelet-rich plasma (PRP) in view of their safety profiles. However, such an injection should only be offered after conservative treatment has failed, as 80% of patients recover well after initial conservative management.

    We describe a series of three patients who sustained multiplanar sacral fracture with spinopelvic dissociation treated with bilateral triangle osteosynthesis supplemented with a gullwing plate. Multiplanar sacral fracture causes the sacrum to divide into two parts which in severe cases, fracture displacement results in neurological injury. Spinopelvic fixation supplemented with a gullwing plate surgical treatment is still a viable option with an acceptable outcome. The average waiting time prior to surgery is 3 weeks.

    Objectives: To evaluate the feasibility of ultrasonographic examination in predicting 4-strand semitendinosus and gracilis tendon (4S-STG) autograft size preoperatively in anterior cruciate ligament reconstruction and to evaluate the use of anthropometric measurement to predict the 4-strand semitendinosus and gracilis tendons (4S-STG) autograft size pre-operatively in anterior cruciate ligament reconstruction.

    Method: Twenty-seven patients were included in this study conducted from 1st January to 31st December 2013. All patients were skeletally mature and scheduled to undergo primary anterior cruciate ligament reconstruction using 4S-STG autograft. Ultrasonographic examination of semitendinosus and gracilis tendons to measure the cross sectional area was conducted and anthropometric data (weight, height, leg length and thigh circumference) was measured one day prior to surgery. True autograft diameters were measured intraoperatively using closed-hole sizing block in 0.5 mm incremental size.

    Results: There is a statistically significant correlation between the measured combined cross sectional area (semitendinosus and gracilis tendons) and 4S-STG autograft diameter (p = 0.023). An adequate autograft size (at least 7 mm) can be obtained when the combined cross sectional area is at least 15 mm2. There was no correlation with the anthropometric data except for thigh circumference (p = 0.037). Autograft size of at least 7 mm can be obtained when the thigh circumference is at least 41 mm.

    Conclusions: Both combined cross sectional area (semitendinosus and gracilis tendons) and thigh circumference can be used to predict an adequate 4S-STG autograft size.

    Background: The study aims to evaluate the short-term functional outcome of open reduction and internal fixation of extraarticular scapular neck and body fractures treated at our center over a period of 2-year duration at a tertiary referral center. Patients and Methods: Between October 2015 and October 2017, we operated on 20 extraarticular scapular neck and body fracture. Ten were available for a one-off assessment. The mean time to surgery was 10 days (range, 3-19 days) and one-off assessment was done within 6-24 months (mean, 13 months). Indications includes (1) medial/lateral displacement (M/L) ≥ 20 mm, (2) M/L ≥ 15 mm if angular deformity ≥ 30°, (3) Angular deformity ≥ 45°, (4) Double lesion of superior shoulder suspensory complex (SSSC), with displacement ≥10 mm in both lesion, (5) Glenopolar angle (GPA) ≤ 22°, and (6) open scapular fracture. The functional outcome was measured using range motion and strength. Patient-reported outcome was assessed using Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire and Short-Form-36 (SF-36) version 1. Results: All patients achieved radiological union at time of assessment. None of the patients had post-operative complications. The mean DASH score was 19.3 (range, 1.7-39.3). All subcategories of SF-36 questionnaire scores between 70 and 89.6, with exception to REE (role limitations due to emotional problems) and REP (role limitations due to physical health). The average range of motion for the injured shoulders; forward flexion 157°, abduction 114°, and external rotation 42°. The strength of operated and non-operated shoulders, respectively, 6.5 and 8.1 kgF of forward flexion, 5.5 and 7.2 kgF of abduction, and 4.1 and 6.3 kgF of external rotation. Conclusion: Open reduction and internal fixation of surgically indicated scapular neck and body fracture is feasible with predictably good functional outcome. The reduced external rotation ROM and strength may be due to the use of Classic Judet approach, however we do not enough data to support this.

    Virtual reality (VR) is one of the state-of-the-art technological applications in the healthcare domain. One major aspect of VR applications in this domain includes virtual reality-based training (VRT), which simplifies the complicated visualization process of diagnosis, treatment, disease analysis, and prevention. However, not much is known on how well the domain knowledge is shared and considered in the development of VRT applications. A pertinent mechanism, known as ontology, has acted as an enabler toward making the domain knowledge more explicit. Hence, this paper presents an overview to reveal the basic concepts and explores the extent to which ontologies are used in VRT development for medical education and training in the healthcare domain. From this overview, a base of knowledge for VRT development is proposed to initiate a comprehensive strategy in creating an effective ontology design for VRT applications in the healthcare domain.

    The application of bone substitutes and cements has a long standing history in augmenting fractures as a complement to routine fracture fixation techniques. Nevertheless, such use is almost always in conjunction with definite means of fracture fixation such as intramedullary pins or bone plates. The idea of using biomaterials as the primary fixation bears the possibility of simultaneous fixation and bone enhancement. Intramedullary recruitment of bone cements is suggested in this study to achieve this goal. However, as the method needs primary testings in animal models before human implementation, and since the degree of ambulation is not predictable in animals, this pilot study only evaluates the outcomes regarding the feasibility and safety of this method in the presence of primary bone fixators. A number of two sheep were used in this study. Tibial transverse osteotomies were performed in both animals followed by external skeletal fixation. The medullary canals, which have already been prepared by removing the marrow through proximal and distal drill holes, were then injected with calcium phosphate cement (CPC). The outcomes were evaluated postoperatively by standard survey radiographs, morphology, histology and biomechanical testings. Healing processes appeared uncomplicated until week four where one bone fracture recurred due to external fixator failure. The results showed 56% and 48% cortical thickening, compared to the opposite site, in the fracture site and proximal and distal diaphyses respectively. This bone augmentative effect resulted in 264% increase in bending strength of the fracture site and 148% increase of the same value in the adjacent areas of diaphyses. In conclusion, IMCO, using CPC in tibia of sheep, is safe and biocompatible with bone physiology and healing. It possibly can carry the osteopromotive effect of the CPCs to provide a sustained source of bone augmentation throughout the diaphysis. Although the results must be considered preliminary, this method has possible advantages over conventional methods of bone fixation at least in bones with compromised quality (i.e. osteoporosis and bone cysts), where rigid metal implants may jeopardize eggshell cortices.

    Osteonecrosis is a disruption of blood supply to the bone which results in bone cell death. Post-traumatic osteonecrosis of distal tibia rarely happens as compared to osteonecrosis which affects other parts of the musculoskeletal system. We report a case of osteonecrosis of distal tibia in an adult male following an open fracture dislocation of the right ankle. Initial surgery of wound debridement with a temporary external fixator was performed for ankle stabilization. The patient underwent internal fixation once the subcutaneous tissue was deemed suitable. A year later, he had worsening ankle pain which affected his daily activities. Magnetic resonance imaging showed osteonecrosis of the distal tibia, osteochondral injury of the medial tibial plafond, and medial talus with lateral ligament complex injuries. Autologous iliac bone grafting was applied to the distal tibia and a cell-free hyaluronic acid-based scaffold (Hyalofast®) was used to address the bone osteonecrosis and osteochondral injury respectively. Visual analog score (VAS), AOFAS hindfoot score, and ankle range of motion improved at three months and significantly increased after six months and one year post-operatively.

    Tuberculosis is an infection that can occur in every organ of the body, but it rarely affects the wrist joint. We report a rare case of a male patient with wrist tuberculosis with a subtle presentation. Our patient's left wrist had been swollen for four months and progressively worsened, becoming ulcerated one week prior to presentation to our center. He was asymptomatic, but a previous radiograph showed global destruction of the wrist joint. Clinical investigations, that is, polymerase chain reaction test for tuberculosis and histopathological examination, showed classic findings of tuberculosis, which lead to the initiation of anti-tuberculosis treatment.

    In the field of medical imaging, the classification of brain tumors based on histopathological analysis is a laborious and traditional approach. To address this issue, the use of deep learning techniques, specifically Convolutional Neural Networks (CNNs), has become a popular trend in research and development. Our proposed solution is a novel Convolutional Neural Network that leverages transfer learning to classify brain tumors in MRI images as benign or malignant with high accuracy. We evaluated the performance of our proposed model against several existing pre-trained networks, including Res-Net, Alex-Net, U-Net, and VGG-16. Our results showed a significant improvement in prediction accuracy, precision, recall, and F1-score, respectively, compared to the existing methods. Our proposed method achieved a benign and malignant classification accuracy of 99.30 and 98.40% using improved Res-Net 50. Our proposed system enhances image fusion quality and has the potential to aid in more accurate diagnoses.

    We report the case of a 14-year-old girl who presented with a one-month history of back pain and bilateral lower limb weakness preceded by constitutional symptoms. She neither had a family history of malignancy nor a previous history of trauma. A series of imaging procedures revealed an aggressive lesion of the T12 vertebra with a large soft-tissue component and intraspinal extension leading to spinal cord compression causing cord edema. She underwent urgent posterior instrumentation and fixation of T9 to T12 vertebrae due to worsening neurological deficits. Adjuvant and neoadjuvant chemotherapy with palliative spinal stabilisation were also performed. Features of the lesion were highly consistent with ES on immunohistochemical study and fluorescence in situ hybridization (FISH) analysis for the EWSR1 gene. Postoperatively, both of her lower limbs improved in power and she benefited from regular physiotherapy.

    BACKGROUND: Diabetic foot infection is a worldwide health problem is commonly encountered in daily practice. This study was conducted to identify the microbiological profile and antibiotic sensitivity patterns of causative agents identified from diabetic foot infections (DFIs). In addition, the assessment included probable risk factors contributing to infection of ulcers that harbour multidrug-resistant organisms (MDROs) and their outcomes.

    METHODS: We carried out a prospective analysis based on the DFI samples collected from 2016 till 2018. Specimens were cultured with optimal techniques in addition to antibiotic susceptibility based on recommendations from The Clinical and Laboratory Standards Institute (CLSI). A total of 1040 pathogens were isolated with an average of 1.9 pathogens per lesion in 550 patients who were identified with having DFIs during this interval.

    RESULTS: A higher percentage of Gram-negative pathogens (54%) were identified as compared with Gram-positive pathogens (33%) or anaerobes (12%). A total of 85% of the patients were found to have polymicrobial infections. Pseudomonas aeruginosa (19%), Staphylococcus aureus (11%) and Bacteroides species (8%) appeared to be the predominant organisms isolated. In the management of Gram-positive bacteria, the most efficacious treatment was seen with the use of Vancomycin, while Imipenem and Amikacin proved to be effective in the treatment of Gram-negative bacteria.

    CONCLUSION: DFI's are common among Malaysians with diabetes, with a majority of cases displaying polymicrobial aetiology with multi-drug resistant isolates. The data obtained from this study will be valuable in aiding future empirical treatment guidelines in the treatment of DFIs. This study investigated the microbiology of DFIs and their resistance to antibiotics in patients with DFIs that were managed at a Tertiary Care Centre in Malaysia.
