Managing epilepsy in Ramadan: Guidance for healthcare providers and patients.

Ramadan is a regularly recurring period of fasting that takes place in the ninth month of the Islamic calendar. For this period, adult Muslims refrain from eating and drinking between dawn and sunset. The variation in summer daylight hours means that at temperate latitudes, fasting can last up to 20 h. It is already recognized that epilepsy control can deteriorate during Ramadan, and this may be explained by fasting-related changes to adherence to antiseizure drug regimes. This article provides specific advice to help Muslim patients prepare for Ramadan and reduce chances of exacerbation in epilepsy. In addition to advice around sleep hygiene, it explores the use of drugs or preparations of drugs that will demonstrate reduced variation during periods of fasting.

Hypocupremia associated cytopenia and myelopathy: a national retrospective review.

Copper is an essential trace element that is involved in a number of important enzymatic processes throughout the body. Recent single case reports and small studies have shown that deficiency of copper can cause reversible haematological changes and irreversible neurological injury. We chose to undertake a national study, looking at all cases of copper deficiency in Scotland over a 5-yr period using information from a national reference laboratory. From 16 identified patients, we determined that 86% had both haematological and neurological features of copper deficiency, while 18% had haematological features only at presentation. Twelve of the sixteen patients had high serum zinc concentrations (>18 µm/L) nine patients were using zinc-containing dental fixatives at time of diagnosis. 94% of patients had haematological features as an initial manifestation of copper deficiency, which included anaemia, thrombocytopenia and neutropenia. Patients who underwent later bone marrow testing had appearances in keeping with refractory cytopenia with multilineage dysplasia, refractory anaemia with excess of blasts, unclassified marrow dysplasia or probable myelodysplasia (MDS). 75% of patients had neurological symptoms or signs, including progressive walking difficulties and paraesthesia, or gait difficulties without sensory signs. Clinical examination was in keeping with spastic paraparesis (either with or without sensory neuropathy). Magnetic resonance imaging (MRI) showed multifocal T2 hyper intense foci in the subcortical white matter, and atrophy of the cerebrum and cerebellum was also seen on computerised tomography (CT). MRI of the spinal cord showed signal change in the dorsal columns in either the cervical or thoracic cord. 93% of cytopenias responded to copper replacement and addressing the original cause of the copper deficiency, but only 25% of patients had improvement in their neurological function, while 33% deteriorated and 42% remained unchanged. Our study demonstrates that copper deficiency is an under-recognised cause of several types of cytopenia, which are reversible but can progress to significant neurological injury if left untreated. We illustrate the importance of identifying these patients early to prevent irreversible neurological injury.
