INTRODUCTIONThis study aimed to explore the level of knowledge of Muslim patients with diabetes mellitus (DM) regarding DM and the self-management of DM when fasting during Ramadan.
METHODSMuslim patients with DM attending the Diabetes Centre of Singapore General Hospital, Singapore, were surveyed on their knowledge of DM and self-management of DM when fasting during Ramadan. Data on patient demographics, DM history and management of DM during the previous Ramadan was also collected. RESULTS A total of 92 patients (34 male, 58 female) were surveyed. The mean age of the patients was 53.4 ± 13.3 years.The patients were either Malay (91.3%) or Indian (8.7%), and most (66.3%) had at least a secondary school education. Most (89.1%) had Type 2 DM. The mean duration of DM was 8.7 ± 5.1 years and mean pre-Ramadan haemoglobin A1c was 8.4% ± 1.8%. DM treatment consisted of insulin therapy (37.0%), oral glucose-lowering drugs (35.9%) and combined therapy (22.8%). The mean DM knowledge score was 58.8% for general knowledge and 75.9% for fasting knowledge. During the previous Ramadan, although 71.4% of the patients consulted their physicians, 37.3% did not monitor their blood glucose levels and 47.0% had hypoglycaemic episodes. Among those who had hypoglycaemia, 10.8% continued to fast.CONCLUSION Unsafe self-management practices were observed among DM patients who fasted during Ramadan. Efforts should be made to bridge the gap between knowledge of DM and self-management of DM.
A 24-year-old Chinese woman with Graves' disease presented with myositis two months after treatment with carbimazole. The patient's myositis resolved with hydration and cessation of carbimazole. No other causes of myositis were found, and a change in the medication to propylthiouracil was uneventful. Review of the literature suggests a possible genetic susceptibility, as the majority of reported cases are Asian in origin, similiar to patients who present with thyrotoxic periodic paralysis. Changing the antithyroid drugs (ATDs) administered, decreasing the dose of pre-existing ATDs in the treatment regimen or addition of levothyroxine has been shown to result in clinical improvement of this complication. These observations suggest various mechanisms of carbimazoleinduced myositis in the treatment of Graves' disease, including the direct effect of ATDs on myocytes, immune-related responses secondary to ATDs and rapid decrements in thyroid hormone, with ensuing myositis.
Head and neck paragangliomas that are exclusively or predominantly dopamine-secreting are rare. Surgery and/or radiotherapy are modalities for locoregional tumoral control. Little is known about the efficacy of radiotherapy for biochemical control in such tumors. We report a 62-year-old Chinese man with bilateral carotid body tumors which were exclusively dopamine secreting. The left-sided tumor invaded the skull base and encased the left carotid artery. Surgery was not performed due to high risk of morbidity and mortality. The patient received external beam radiotherapy to bilateral neck regions. Progressive decline and eventual normalization of urinary dopamine excretion was seen together with a slight reduction in tumor size. This is the first report demonstrating the efficacy of radiotherapy for both biochemical and locoregional control of functioning carotid body paragangliomas.
Hyperglycemia rarely manifests as hemichorea-hemiballism (HH), which is characterized by simple partial motor seizures. One of the difficulties in the management of hyperglycemia-induced HH is the failure to recognize this entity due to its relatively uncommon presentation. We herein present a case series of hyperglycemia-associated dyskinesias, highlighting the different possible clinical presentations of this entity. Both hyperglycemia and hyperosmolality are probable predisposing factors, while ketoacidosis has a protective role in preventing the dyskinesias. One of our patients had ketotic hyperglycemia leading to HH, a previously unreported finding. Early recognition of this entity is crucial as prompt glycemic control leads to the resolution of symptoms and signs.
