Objectives To evaluate the efficacy and safety of tacrolimus ointment 0.1% in adult and 0.03% in
pediatric patients with moderate to severe atopic dermatitis in Malaysia.
Methods This is an open-labeled and single arm multi-center study. 36 adult and 37 pediatric
patients were enrolled. Tacrolimus ointment is applied twice daily for four weeks. The primary
efficacy outcome is based on the Physician’s Global Evaluation of Clinical Response (PG) at Week
4. The secondary efficacy outcomes are Eczema Area and Severity Index (EASI) score, changes
from baseline in individual scores of signs and symptoms and body surface area affected and
Patients Assessment of Treatment Effects.
Results Overall success rate were 97.1% and 91.2% in the adult and pediatric groups respectively.
The decline in EASI, percentage of total BSA affected and patient’s assessment of pruritus were
significant (P<0.001). Of adults and pediatric patients, 97.2% and 75.7% respectively reported
adverse effect. The most common adverse effect reported was skin burning sensation in 91.7% adult
patients and pruritus in 67.6% pediatric patients.
Conclusion Tacrolimus ointment 0.1% in adult and 0.03% in pediatric patients is effective for the
treatment of moderate to severe atopic dermatitis in Malaysia.

INTRODUCTION:
Diabetes increases the risk of ischaemic stroke especially among Asians. This study aims to investigate contemporaneous long-term cardiovascular outcomes of ischaemic stroke patients with diabetes in a multi-ethnic Asian cohort.
METHODS:
Consecutive patients with ischaemic stroke were recruited from the National University Hospital, Singapore. Data on age, gender, ethnicity, risk factors (including diabetes status and body mass index [BMI]), stroke severity and mechanisms were collected. These patients were followed up until the day of the first cardiovascular event or July 2016, whichever was earlier. The primary endpoint was the time from enrolment to the first occurrence of a composite of cerebrovascular and coronary artery events.
RESULTS:
Between July 2011 and December 2013, 720 patients (mean age 60.6 years, 71% men, 43% with diabetes, median National Institute Health Stroke Severity scale 2) were enrolled and followed up. A total of 175 cardiovascular events occurred during a median follow-up of 3.25 years (6.90 events per 1,000 person-month), comprising 133 cerebrovascular and 42 coronary artery events. The adjusted hazard ratio of diabetes was 1.50 (95% CI 1.08-2.10). In a multivariable Cox proportional hazards model, Malay and Indian ethnicities, BMI <23kg/m2 and a prior diagnosis of diabetes were identified as independent predictors of recurrent cardiovascular events.
CONCLUSION
Our study provides quantitative data on the event rates of ischaemic stroke patients with diabetes. These findings provide insights on stroke predictors in a multi-ethnic Asian population, which may have implications in the design of future interventional studies.

Introduction: To evaluate the clinical relevance of the
painful anterior apprehension test in shoulder instability.
Materials and methods: We performed a retrospective
study of 155 patients that underwent arthroscopic anterior
Bankart repair between 2014–2016. Exclusion criteria were
previous ipsilateral shoulder surgery, bony Bankart lesions,
glenohumeral osteoarthritis and concomitant surgery
involving rotator cuff tears, biceps tendon pathology and
superior labrum from anterior to posterior (SLAP) lesions.
The study cohort was divided into three groups:
apprehension test with apprehension only, apprehension test
with pain only, and apprehension test with both apprehension
and pain. Patient demographics, clinical characteristics,
radiological imaging, arthroscopy findings and surgical
outcomes (Constant, American Shoulder and Elbow
Surgeons (ASES), SF-36 scores) were evaluated.
Results: A total of 115 (74.2%) had apprehension only, 26
(16.8%) had pain only and 14 (9.0%) had pain and
apprehension with the apprehension test. Univariate analysis
showed significant differences between the groups in
patients with traumatic shoulder dislocation (p=0.028),
patients presenting with pain (p=0.014) and patients
presenting with recurrent dislocations (p=0.046). Patients
with a purely painful apprehension test were more likely to
have a traumatic shoulder dislocation, more likely to present
only with pain, and less likely to present with recurrent
shoulder dislocations. Multivariate analysis showed that
none of these factors alone were significant as single
predictors for shoulder instability. All three groups were
otherwise similar in patient profile, MRI and arthroscopic
assessments, and clinical outcomes of surgery. Excellent
clinical outcomes were achieved in all groups with no
difference in pre-operative and post-operative scores across
all groups at all time points.
Conclusion: The painful apprehension test may suggest
underlying shoulder instability.

Introduction: To describe the duration of survival among
bone tumour patients with endoprosthesis reconstruction and
to determine frequency of implant failure, revision of
surgery, and amputation after endoprosthesis reconstruction.
Materials and methods: A retrospective cross-sectional
review of all patients with either primary bone tumour or
secondary bone metastases treated with en bloc resection and
endoprosthesis reconstruction from January 2008 to
December 2020.
Results: A total of 35 failures were recorded among the 27
(48.2%) patients with endoprostheses. Some of the patients
suffered from one to three types of modes of failure on
different timelines during the course of the disease. Up to
eight patients suffered from more than one type of failure
throughout the course of the disease. Out of all modes of
failure, local recurrence (type 5 failure) was the most
common, accounting for 25.0% of all failure cases. Four
patients (7.1%) eventually underwent amputation, which
were either due to infection (2 patients) or disease
progression causing local recurrence (2 patients).
Conclusion: The overall result of endoprosthesis
reconstruction performed in our centre was compatible with
other centres around the world. Moreover, limb salvage
surgery should be performed carefully in a selected patient
group to maximise the benefits of surgery.
