Sacral tumours often present surgical resection and reconstruction challenges. Wide resections result in large sacral defects and neoadjuvant radiotherapy impairs wound healing. The wounds need to be covered with bulky, well-vascularised, healthy tissues. We present 2 cases where large sacral defects were reconstructed following tumour resection. Both defects were reconstructed with inferiorly based, transpelvic, pedicled vertical rectus abdominis myocutaneous flaps. This is a robust flap and carries a well-vascularised muscle bulk and skin paddle. The donor site is distant from the lesion site and is thus unaffected by both the resection and radiotherapy. This is a useful flap for reconstructing large sacral defects.
BACKGROUND: Public knowledge regarding Parkinson's disease (PD) is important to facilitate good health-seeking behavior, but the literature on this topic is scarce.
OBJECTIVE: We aimed to explore the level of public knowledge regarding PD in a large multiethnic urban Asian cohort, and (as a secondary aim) in a smaller cohort of PD patients and caregivers.
METHODS: A Knowledge of PD Questionnaire (KPDQ) was developed and administered to members of the Malaysian general public, and to PD patients and caregivers. The KPDQ tests recognition of PD symptoms and general knowledge regarding PD.
RESULTS: 1,258 members of the general public completed the KPDQ. Tremor was the most widely recognized symptom (recognized by 79.0% of respondents); however, 83.7% incorrectly believed that all PD patients experience tremor. Memory problem was the most widely recognized NMS. Overall, motor symptoms were better recognized than NMS. Common misperceptions were that there is a cure for PD (49.8%) and that PD is usually familial (41.4%). Female gender, Chinese ethnicity, tertiary education, healthcare-related work, and knowing someone with PD were independently associated with higher KPDQ scores. PD patients (n = 116) and caregivers (n = 135) demonstrated superior knowledge compared with the general public group, but one-third of them believed that PD is currently curable.
CONCLUSIONS: This is the only study on public knowledge regarding PD in Asia. Important gaps in knowledge were evident, which could present a barrier to early diagnosis and appropriate treatment of PD. This highlights the need for targeted education campaigns and further research in this area.
