Effect of l-carnitine supplementation on muscle cramps induced by stroke: A case report.

l-carnitine, a compound responsible for transportation of acyl groups across cell membranes and modulating intracellular acyl-coenzyme A levels, is reported to reduce muscle cramps in patients with liver cirrhosis and diabetes and those on dialysis. A 79-y-old man with right-sided paralysis was admitted to our hospital and diagnosed with cerebral infarction. Nocturnal leg cramps appeared in the affected side and caused sleep disturbance. Supplementation with l-carnitine reduced the number of nocturnal leg cramps and alleviated sleep disturbance. It also plays an important role in nerve protection and treatment for carnitine deficiency. Patients with stroke-induced paralysis experience muscle wasting, which might reduce pooled carnitine in the affected side. This case suggests that stroke may cause localized carnitine deficiency, and l-carnitine supplementation might be effective for muscle cramps induced by stroke. To the best of our knowledge, this is the first case of l-carnitine supplementation for muscle cramps triggered by cerebral infarction.

[A case of mucinous adenocarcinoma of the sigmoid colon with disseminated carcinomatosis of the bone marrow successfully treated with FOLFOX4/bevacizumab].

A 68-year-old man complaining of back pain was given the diagnosis of mucinous adenocarcinoma of the sigmoid colon with disseminated carcinomatosis of bone marrow and disseminated intravascular coagulation(DIC). We started chemotherapy using FOLFOX4. After we confirmed that DIC had improved following 2 courses of FOLFOX4, bevacizumab was added to FOLFOX4. Laboratory studies revealed a serum CEA level of 11, 432 ng/mL, which improved to 245 ng/mL after a total of 9 courses of chemotherapy. Chemotherapy is continuing as scheduled at 6 months from the onset of this disease.

[Dropped head plus syndrome; a case report].

We reported a patient with so-called "dropped head plus syndrome", a non-progressive myopathy characterized by striking neck extensor weakness followed by progressive limb weakness which is well controlled by azathioprine. This 74-year-old man complained of neck and shoulder fatigue followed by progressive neck extensor weakness over 7 months. On physical examination, neck extensor strength was 4/5 on the MMT scale, but the remainder of the neurological examination and blood tests were normal. Needle EMG showed myopathic changes in the right trapezius and biceps brachialis muscles. Without any treatment, he developed weakness of upper and lower limb muscles about 8 months later, and Gowers' sign was positive. Blood test and needle EMG was unchanged. Muscle biopsy of the left trapezius, deltoid and supraspinatus muscles disclosed nonspecific myopathic changes consisting of variation in fiber size with disorganized intermyofibrillar networks in all the fibers, and there were rimmed vacuoles in some fibers of the deltoid muscle. There was no change on corticosteroids, but there was a dramatic improvement with azathioprine and his muscle symptoms disappeared. We, therefore, made the diagnosis of "dropped head plus syndrome". This appears to be the first such case in Japan.
