Background: A thymectomy is considered effective for patients with myasthenia gravis (MG).
Although a few studies have described the role of a thymectomy in the treatment of MG in Asians
countries, there are no published data on the application of this surgical approach for MG in
Malaysia. We aimed to describe the clinical outcomes of MG patients who underwent a thymectomy
and the factors affecting these outcomes.
Methods: This was a retrospective study involving 16 patients with MG who underwent a
thymectomy at the Hospital Universiti Sains Malaysia (HUSM) from January 2002 until December
2012, with a follow-up period ranging from 3–120 months.
Results: The study consisted of 16 patients aged 22–78 years, 10 of whom were males. The overall
remission/improvement rate was 87.5%, and the rate of clinical outcomes classified as unchanged/
worsened was 12.5%. Thymomamatous or non-thymomamatous MG, histology features, Osserman
stage and the duration of follow-up were not significant prognostic factors. Post-operative mortality
was 6.2% (1 of 16 patients died of septic shock).
Conclusion: A thymectomy seems to be an effective treatment for MG, with low surgical
morbidity. Patients with a lower Osserman stage and those with/without thymomas had favourable
outcomes.

We report a case of open fracture of the clavicle with subclavian artery and vein laceration and
perforation of the parietal pleural below the first rib that caused massive haemothorax. Emergency
thoracotomy and exploration followed by repair of both vessels were able to salvage the patient and
the extremity.

Background: Perioperative red blood cell (RBC) transfusion in coronary artery bypass
grafting (CABG) has both benefits and harms. Our aim was to study the association between
perioperative RBC transfusion and its adverse outcomes.
Methods: This was a retrospective study of patients who underwent isolated CABG in
Hospital Universiti Sains Malaysia, Kelantan, Malaysia, from 1 January 2013 until 31 December
2017. Data were collected from medical records, and comparisons were made between patients
who received perioperative RBC transfusions and those who did not have adverse outcomes after
CABG.
Results: A total of 108 patients who underwent isolated CABG were included in our study,
and 78 patients received perioperative RBC transfusions. Patients who received perioperative
RBC transfusions compared to those who did not were significantly more likely to develop
prolonged ventilatory support (21.8% versus 0%, P = 0.003), cardiac morbidity (14.1% versus 0%,
P = 0.032), renal morbidity (28.2% versus 3.3%, P = 0.005) and serious infection (20.5% versus
3.3%, P = 0.037). With each unit of packed RBC transfusions, there was a significantly increased
risk of prolonged ventilatory support (adjusted odds ratio [AOR] = 1.45; 95% confidence interval
[CI] = 1.20–1.77; P < 0.001), cardiac morbidity (AOR =1.40; 95%CI = 1.01–1.79; P = 0.007), renal
morbidity (AOR = 1.23; 95%CI = 1.03–1.45; P = 0.019) and serious infection (AOR = 1.31; 95%CI =
1.07–1.60; P = 0.009).
Conclusion: Perioperative RBC transfusion in isolated CABG patients is associated with
increased risks of developing adverse events such as prolonged ventilatory support, cardiac
morbidity, renal morbidity and serious infection.
