The Singapore Health Services cluster (SingHealth) radiology film archives are a valuable repository of local radiological cases dating back to the 1950s. Some of the cases in the archives are of historical medical interest, i.e. cerebral angiography in the workup of patients with hemiplegia. Other cases are of historical social interest, being conditions seen during earlier stages of Singapore's development, i.e. bound feet. The archives form a unique portal into the development of local radiology as well as the national development of Singapore. A selection from the archives is published in commemoration of the International Day of Radiology in 2020, as well as the 200th anniversary of the Singapore General Hospital in 2021. This pictorial essay comprises gastroenterology, musculoskeletal and obstetrics and gynaecology cases from the archives.

Introduction: Diabetic foot infection, a complication that is
associated with lower-limb amputation, incurs a huge
economic burden to the hospital and health care system of
Malaysia. The bacteriological profile of pathogens in
diabetic foot infections in Malaysia has been sparsely
studied. We investigated the microbiology of diabetic foot
infections in patients admitted to the district hospitals on
the east coast of Malaysia.
Methods: A retrospective analysis was conducted in three
district hospitals (Hospital Kuala Lipis, Hospital Bentong
and Hospital Raub) in Malaysia from 1st of January 2016 to
31st December 2016. The clinical specimens were cultured
using Clinical and Laboratory Standards Institute (CLSI)
guidelines. Antibiotic sensitivity testing to different
antibiotics was carried out using the disc diffusion method.
Result: A total of 188 pathogens were isolated from 173
patients, with an average of 1.09 pathogens per lesion.
Majority of the pathogens isolated were gram negative
pathogens (73.4%). The most commonly isolated pathogens
were Staphylococcus aureus (17.5%). This was followed by
Klebsiella spp. (17%), Pseudomonas spp. (15.4%) and
Proteus spp. (13.8%). Gram positive pathogens were
sensitive to most of the antibiotics tested except penicillin
and fusidic acid. Gram negative pathogens were sensitive to
all antibiotics tested except ampicillin and
amoxicillin/clavulanic acid. Amikacin provide coverage for
all gram negative pathogens in DFI.
Conclusion: For the management of patient with infection in
diabetic foot, the choice of antibiotic therapy depends on the
sensitivity of the pathogens, the severity of the infection, the
patient’s allergies history, toxicity and excretion of the
antibiotics.
5.Epilepsy care: Work, upbringing, leisure, and Chinese culture
Neurology Asia 2019;24(3):197-202
Stigma in epilepsy arises from the misconceptions and prejudices rooted in the patient’s culture and
traditions. Upbringing also has an important impact on the quality of life of epilepsy patients. In Chinese tradition, the main purpose of life is to be a “gentleman” 君子, to fully express the true human nature. The essence of being a gentleman is “benevolence” and “virtue”. According to Zhuangzi’s concept of “virtue overcoming deformity” 德充符, virtue can prevail over physical deficiencies. Consistent with such a principle, a person with epilepsy should receive high honour if he can demonstrate the character of a “gentleman”. In - traditional Chinese culture, the sense of shame is the foundation of morality; “feeling shame” 知耻 and “being shameless” 无耻 are important moral concepts. A gentleman has a sense of shame, whereas a “petty person” 小人 is shameless. However, the ability to resist feeling inappropriate shame - “not feeling ashamed” 不耻 is also a trait of the gentleman. Thus, based on traditional Chinese philosophy, one should resist feeling ashamed for having epilepsy. Chinese culture emphasizes the importance of exerting vitality in the presence of adversity; people with epilepsy who do not feel ashamed of their deficiency is manifesting such a vitality. Traditional Chinese culture takes a positive attitude towards hardship and adversity, that it is essential for developing character and skills. Overcoming adversity requires responsibilities, the pre-requisite is personal freedom. Thus, allowing freedom and nurturing independence is consistent with traditional Chinese attitude to upbringing.

Introduction:
Solat or prayer, as one of the five pillars of Islam, is associated with bio-psycho-social benefits in Muslim patients. Many Muslim patients neglected solat while being hospitalized as they are unaware of the convenience (rukhsoh) available for them. Ibadah Friendly Hospital Courses have been conducted in different states of Malaysia to impart knowledge to the hospital staff who can in turn educate their patients. This study aims to construct a content-validated assessment tool to assess the effectiveness of a state-level Hospital Mesra Ibadah course.
Materials and methods:
A self-administered questionnaire was constructed and content-validated by a panel of three experts (two religious teachers and one consultant spine surgeon). All 15 questions achieved item-level content validity index (I-CVI) of 1.00 after two rounds of validation. The questionnaires were distributed to participants of a state-level Hospital Mesra Ibadah course to compare the participants’ pre-course and post-course test scores.
Results:
A total of 88 participants (48.9%) were included in this study. There was a significant difference in the pre-course test mean score and post-course test mean score among the participants. There was also a significant reduction of unsure answers after the course. There was no significant association found between the gender, place of work and occupation with the pre-post test score difference.
Conclusion
This study demonstrates that the Hospital Mesra Ibadah course is effective in imparting as well as consolidating the knowledge among participants, hence it should be routinely organized to benefit more participants.

Introduction: ‘InTec Blood Grouping Test kit’ using solid-phase technology is a new method which may be used at outdoor blood donation site or at bed side as an alternative to the conventional tile method in view of its stability at room temperature and fulfilled the criteria as point of care test. This study aimed to compare the efficiency of this solid phase method (InTec Blood Grouping Test Kit) with the conventional tile method in determining the ABO and RhD blood group of healthy donors. Methods: A total of 760 voluntary donors who attended the Blood Bank, Penang Hospital or offsite blood donation campaigns from April to May 2014 were recruited. The ABO and RhD blood groups were determined by the conventional tile method and the solid phase method, in which the tube method was used as the gold standard. Results: For ABO blood grouping, the tile method has shown 100% concordance results with the gold standard tube method, whereas the solid-phase method only showed concordance result for 754/760 samples (99.2%). Therefore, for ABO grouping, tile method has 100% sensitivity and specificity while the solid phase method has slightly lower sensitivity of 97.7% but both with good specificity of 100%. For RhD grouping, both the tile and solid phase methods have grouped one RhD positive specimen as negative each, thus giving the sensitivity and specificity of 99.9% and 100% for both methods respectively. Conclusion: The ‘InTec Blood Grouping Test Kit’ is suitable for offsite usage because of its simplicity and user friendliness. However, further improvement in adding the internal quality control may increase the test sensitivity and validity of the test results.

ervical spine injury is commonly associated with road-traffic accidents. The true incidence of cervical spine injuries is unknown due to under-reporting of such injuries. Cervical spine injury is associated with high morbidity and mortality if it is missed. With the advancement of imaging modalities, the number of missed cervical injuries has reduced. Nevertheless, some clinicians are dependent solely on imaging tools to rule out cervical spine injury in a trauma victim. We report two cases of “near miss” C6 fracture to highlight the importance of a detailed clinical history and clinical examination with imaging as an adjunct to rule out cervical injury.

Introduction: Microparticles are membrane bound vesicles, measuring less than 1.0 um, which are released during cellular activation or during apoptosis. Studies have shown that these circulating microparticles play a role in coagulation, cell signaling and cellular interactions. Increased levels of circulating microparticles have been observed in a number of conditions where there is vascular dysfunction, thrombosis and inflammation. The objective of this study was to determine the various plasma-derived microparticles in patients with polycythaemia vera (PV) in Universiti Kebangsaan Malaysia Medical Centre and to compare them with normal control. Methods: A total of 15 patients with PV and 15 healthy volunteers were included in this cross-sectional descriptive study. Plasma samples from both patients and healthy volunteers were prepared and further processed for isolation of microparticles. Flow cytometry analyses were then carried out in all samples to determine the cellular origin of the microparticles. Full blood count parameters for both groups were also collected. Data collected were analyzed using SPSS version 12.0. Results: Patients with PV had a significantly higher percentage of platelet derived microparticles compared to healthy controls (P <0.05). The control group had a higher level of endothelial derived microparticles but the differences were not statistically significant (P > 0.05). Conclusion: The median percentage of positive events for platelet derived microparticles was higher in patients with PV compared to normal healthy controls.

Objective: To evaluate antifungal and cytotoxic activities of four underutilised fruit species, i.e. Artocarpus altilis (breadfruit), Cynometra cauliflora (nam-nam), Mangifera pajang (M. pajang) (Bambangan) and Physalis minima (wild gooseberry). Methods: Extracts from the fresh flesh of Artocarpus altilis and Cynometra cauliflora, the flesh and kernel of M. pajang, and the whole fruit of Physalis minima were obtained by sequential extraction using hexane, chloroform, ethyl acetate, ethanol, methanol and distilled water. Each extract was assessed against six species of human fungal pathogens using a colourimetric broth microdilution method. The cytotoxicity was evaluated using African monkey kidney epithelial (Vero) cells. Results: All 30 extracts showed inhibitory activity against Cryptococcus neoformans. However, none of the extracts were active against Aspergillus fumigatus. The ethanol, methanol and water extracts from the kernel of M. pajang fruit showed the strongest activity against three species of Candida and Trichophyton interdigitale, with a minimum inhibitory concentration range of 0.001 - 0.630 mg/mL. The corresponding mean 50% cytotoxic concentrations for these three extracts were 358.7, 158.4 and 261.3 μg/mL, respectively against Vero cells. In contrast, the flesh of M. pajang fruit (hexane, chloroform and ethyl acetate extracts) showed statistically significant (P<0.001; ANOVA) strong toxicity against the cells, with 30.6, 13.5 and 22.2 μg/mL of mean values of 50% cytotoxic concentrations, respectively. Conclusions: The results suggest that the bioactivity of the kernel of M. pajang fruit is more selective towards fungi and thus is a potential source of new antifungal agents.
