This is a case report of subcutaneous mycosis presenting
as a non-healing left calf ulcer in an immunocompromised
patient. Traumatic inoculation of the causative agent is the
most likely route of infection. The diagnosis requires a
detailed history and high clinical suspicion, confirmed by
histopathological examination. The management requires a
multidisciplinary team approach involving surgeon,
pathologist, physician sub-specialised in infectious disease,
wound care nursing team as well as social support services.
The literature review recommended that the treatment of
choice for such infection is surgical debridement in addition
to optimal antifungal therapy.

Bullous pemphigoid (BP) has a recognized association with solid organ tumors, but is relatively rare in hematological malignancies. We report a 67-year-old male who developed BP after being diagnosed with myelodysplastic syndrome and refractory anemia with excess of blast (RAEB). Skin biopsy elucidated sub-epidermal bulla using direct immunofluorescence, revealing linear C3 and IgG deposits along the basement membrane. His BP was recalcitrant to the conventional treatment and only responded to a combination of high dose oral prednisolone and azathioprine. The relative refractory nature of his condition and concurrent RAEB supports a paraneoplastic nature.

INTRODUCTIONThis study aimed to evaluate the two-year clinical outcomes of arthroscopic Bankart repair augmented by plication of the inferior glenohumeral ligament (IGHL) via horizontal mattress suturing.
METHODSThis study was a retrospective analysis of 76 arthroscopic Bankart repairs by a single surgeon from 2004 to 2008. Bioabsorbable suture anchors were used, with anchors placed at the 5:30, 4 and 3 o'clock positions of the right shoulder (correspondingly at the 6:30, 8 and 9 o'clock positions for the left shoulder). The lower most anchor was tied via horizontal mattress suture with plication of the IGHL, while the remaining two anchors were tied using simple sutures. The patients were postoperatively assessed, clinically and using the University of California Los Angeles (UCLA) shoulder rating scale.
RESULTSThe mean age of the patients at the time of presentation was 24.09 ± 7.98 years, and the mean duration of follow-up was 28.7 months. The postoperative recurrence rate of dislocation was 7.89% (six shoulders), of which five shoulders required revision surgeries. Excluding the revision cases, clinical assessment of the strength of the supraspinatus and the range of motion of the operated shoulders at two years post operation were either maintained or full in all patients. Analysis of the UCLA results showed pre- and postoperative mean scores of 25.94 ± 3.43 and 33.77 ± 3.07, respectively (p < 0.05).
CONCLUSIONArthroscopic Bankart repair augmented by plication of the IGHL and anchored via horizontal mattress suturing is a safe and reliable treatment for shoulder instability, with good clinical outcomes and low recurrence rates.

INTRODUCTIONThe fabella, a sesamoid bone sometimes found in the lateral head of the gastrocnemius muscle, often articulates directly with the lateral femoral condyle. This study aimed to determine the incidence of fabellae in an Asian population and to characterise the radiological features of the fabella.
METHODSElectronic radiographs and magnetic resonance imaging films of 80 consecutive patients who underwent knee arthroscopy between May 2005 and October 2009 were reviewed to determine the presence and characteristics of the fabella.
RESULTSThe incidence of fabellae was 31.25% in our study cohort. The median length, thickness, width and distance of the fabella from the lateral femoral condyle were 7.06 mm, 4.89 mm, 6.12 mm and 33.19 mm, respectively. The fabella was consistently bony and located in the lateral head of the gastrocnemius, with 52% of the fabellae having an articulating facet. Fabellae in men were found to be larger than in women, although the difference was not statistically significant. The presence of an articulating groove was associated with increased size of the fabella, but not with the distance between the fabella and its insertion onto the lateral head of the gastrocnemius.
CONCLUSIONThe incidence of fabellae in our population was lower than that in regional studies. They were consistently bony and not all had articulating grooves on the lateral femoral condyle. We found that the larger the fabella, the higher the chances of it having an articulating groove. By defining the radiological characteristics of the fabella, we provide objective parameters to help differentiate the fabella from other loose bodies or calcifications in the knee.

INTRODUCTION:
The impact of noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP) on the risk of malignancy (ROM) in fine-needle aspiration cytology (FNAC) per The Bethesda System for Reporting Thyroid Cytopathology has not been well reported in Singapore.
METHODS:
We retrospectively identified 821 thyroid nodules with preoperative FNAC from 788 patients out of 1,279 consecutive thyroidectomies performed between January 2010 and August 2016 in a tertiary general hospital in Singapore. Possible cases of NIFTP were reviewed for reclassification and the impact of NIFTP on ROM was analysed.
RESULTS:
The incidence of NIFTP was 1.2% (10 out of 821). If NIFTP is considered benign, ROM in Bethesda I through VI were 8.6%, 3.5%, 26.3%, 20.0%, 87.7%, 97.0% versus 8.6%, 4.2%, 28.1%, 26.7%, 89.2% and 100% if NIFTP is considered malignant. Eight patients with NIFTP had follow-up of 15 to 110 months. One had possible rib metastasis as evidenced by I131 uptake but remained free of structural or biochemical disease during a follow-up period of 110 months. None had lymph node metastasis at presentation, nor locoregional or distant recurrence.
CONCLUSION
Classifying NIFTP as benign decreased ROM in Bethesda II through VI, but the benignity of NIFTP requires more prospective studies to ascertain. The impact of NIFTP on ROM in our institution also appears to be lower than that reported in the Western studies.

Introduction: Sarawak has a population that is
geographically and characteristically widely varied. This
study aimed to determine the demographic profile of
patients in Sarawak, Malaysia.
Materials and Methods – A cross-sectional study was
conducted in 2019 at four major haemophilia treatment
centres in Kuching, Sibu, Bintulu and Miri Hospitals,
Sarawak. Demographic and clinical data were collected with
consents from patients.
Results and Discussion: Ninety-six haemophilia patients
were identified - 79(82.3%) haemophilia A(HA) and 17(17.7%)
haemophilia B(HB). Severe haemophilia patients were noted
in 45.6% (36/79) of HA and 64.7% (11/17) of HB. In all 44.3%
of the HA and 52.9% of the HB population had no identifiable
family history of haemophilia. Two-thirds of the patients with
severe HA were on prophylaxis [24/36 (66.7%)] and only onethird [4/11 (36.4%)] in severe HB. Inhibitors developed in 9/79
(11.4%) of the HA population [3/79 (3.8%) high responders].
The median inhibitor titre was not significantly different
between the different treatment groups – on demand versus
prophylaxis (1.0BU versus 2.0BU; z statistic -1.043, p-value
0.297, Mann-Whitney test). None of the patients developed
inhibitory alloantibodies to factor IX. Four HA patients (5.1%)
underwent immune tolerance induction where one case had
a successful outcome. Three severe HA patients received
emicizumab prophylaxis and showed remarkable reduction
in bleeding events with no thromboembolic events being
reported. One female moderate HA patient received
PEGylated recombinant anti-haemophilic factor. Eleven
patients underwent radiosynovectomy. One mild HB patient
succumbed to traumatic intracranial bleeding. Our data
reported a prevalence (per 100,000 males) of 5.40 cases for
all severities of HA, 2.46 cases for severe HA; 1.16 cases for
all severities of HB, and 0.75 cases for severe HB. The
overall incidence of HA and HB was 1 in 11,500 and 1 in
46,000, respectively.
Conclusion: This study outlines the Sarawakian haemophilia
landscape and offers objective standards for forward
planning. Shared responsibilities among all parties are of
utmost importance to improve the care of our haemophilia
population.

INTRODUCTIONWe assessed the predictors of poor glycaemic control among older patients with type 2 diabetes mellitus (T2DM) in Malaysia.
METHODSThis cross-sectional study used the data of 21,336 patients aged ≥ 60 years with T2DM from the Adult Diabetes Control and Management Registry 2008-2009.
RESULTSPredictors of poor glycaemic control were: age groups 60-69 years (odds ratio [OR] 1.96, 95% confidence interval [CI] 1.66-2.33) and 70-79 years (OR 1.43, 95% CI 1.20-1.71); Malay (OR 1.53, 95% CI 1.41-1.66) and Indian (OR 1.32, 95% CI 1.19-1.46) ethnicities; T2DM durations of 5-10 years (OR 1.46, 95% CI 1.35-1.58) and > 10 years (OR 1.75, 95% CI 1.59-1.91); the use of oral antidiabetic agents only (OR 5.86, 95% CI 3.32-10.34), insulin only (OR 17.93, 95% CI 9.91-32.43), and oral antidiabetic agents and insulin (OR 29.42, 95% CI 16.47-52.53); and elevated blood pressure (OR 1.10, 95% CI 1.01-1.20), low-density lipoprotein cholesterol (OR 1.48, 95% CI 1.38-1.59) and triglycerides (OR 1.61, 95% CI 1.51-1.73). Hypertension (OR 0.71, 95% CI 0.64-0.80), hypertension and dyslipidaemia (OR 0.68, 95% CI 0.61-0.75), pre-obesity (OR 0.89, 95% CI 0.82-0.98) and obesity (OR 0.76, 95% CI 0.70-0.84) were less likely to be associated with poor glycaemic control.
CONCLUSIONYoung-old and middle-old age groups (i.e. < 80 years), Malay and Indian ethnicities, longer T2DM duration, the use of pharmacological agents, and elevated blood pressure and lipid levels were associated with poor glycaemic control. The presence of comorbidities, pre-obesity and obesity were less likely to be associated with poor glycaemic control.
