    Abstract The infarct exclusion technique with a xeno-pericardial patch which Komeda and associates firstly reported in 1990 is one of the best procedure to close ventricular septal perforation. A large patch can protect the perforation and the surrounding weak tissue from the internal left ventricular pressure. However, suturing this large patch to the left ventricular wall through the small incision is not technically easy because of the patch design in the ventricle. We modified the design of the patch. This round shaped bovine pericardial patch was sutured continuously to the left ventricular wall. Then, excessive part of the patch was trimmed to make a corn shape. Finally, the corn shaped patch fit the left ventricular wall naturally.

    Abstract Objectives: Daily numbers of COVID-19 in Singapore from March to May 2020, the cause of a surge in cases in April and the national response were examined, and regulations on migrant worker accommodation studied.
    Methods: Information was gathered from daily reports provided by the Ministry of Health, Singapore Statues online and a Ministerial statement given at a Parliament sitting on 4 May 2020.
    Results: A marked escalation in the daily number of new COVID-19 cases was seen in early April 2020. The majority of cases occurred among an estimated 295 000 low-skilled migrant workers living in foreign worker dormitories. As of 6 May 2020, there were 17 758 confirmed COVID-19 cases among dormitory workers (88% of 20 198 nationally confirmed cases). One dormitory housing approximately 13 000 workers had 19.4% of residents infected. The national response included mobilising several government agencies and public volunteers. There was extensive testing of workers in dormitories, segregation of healthy and infected workers, and daily observation for fever and symptoms. Twenty-four dormitories were declared as 'isolation areas', with residents quarantined for 14 days. New housing, for example, vacant public housing flats, military camps, exhibition centres, floating hotels have been provided that will allow for appropriate social distancing.
    Conclusion: The COVID-19 pandemic has highlighted migrant workers as a vulnerable occupational group. Ideally, matters related to inadequate housing of vulnerable migrant workers need to be addressed before a pandemic.

    Abstract Objectives: Long COVID may be a public health concern resulting in a hidden toll of the pandemic years later, on workers and their work ability in the workforce. We illustrate the challenges in diagnosing long COVID in a patient, its associated psychological impact on work and how return-to-work can be better managed and supported from an occupational health perspective.
    Methods: An Occupational Health trainee working as a government public health officer experienced persistent fatigue, decreased effort tolerance, and difficulties in concentration after contracting COVID-19. There were unintended psychological effects arising from the functional limitations that were not explained with a proper diagnosis. This was further complicated with a lack of access to occupational health services for return-to-work.
    Results: He developed his own rehabilitation plan to improve his physical tolerance. Progressive efforts to build up his physical fitness complemented with workplace adjustments helped to overcome his functional limitations and allowed him to effectively return-to-work.
    Conclusion: Diagnosing long COVID continues to remain challenging due to a lack of consensus on a definitive diagnostic criterion. This may give rise to unintended mental and psychological impact. Workers with long COVID symptoms can return-to-work, involving a complex individualized approach to the symptoms' impact on work, and workplace adjustments and job modifications available. The psychological toll on the worker must also be addressed. Occupational health professionals are best placed to facilitate these workers in their journey to return-to-work, with multi-disciplinary delivery models providing return to work services.

    Abstract Tar Ching Aw (1948-2017) or Ching, as he was known to many of us, was highly regarded as an excellent occupational physician and role model. He was an inspirational teacher, a selfless mentor and a great advocate for the discipline of occupational medicine. Among the lessons we can learn from Ching on how to be an excellent occupational physician are the importance of: getting the right training (including clinical training); having good teachers and role models; believing in and being passionate about one's work; delivering quality work on time; networking and being culturally sensitive; thinking of future generations and mentoring them; and having fun and a healthy work life balance.
