We herein report the case of a patient with pancreatic cancer who manifested features of chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) and autoimmune hemolytic anemia (AIHA). A 78-year-old Japanese man presented with AIHA and was treated with steroids and splenectomy. Although the AIHA improved following splenectomy, the patient suffered from sensorimotor neuropathy soon after undergoing surgery. The electrophysiological features indicated demyelinating neuropathy. The neuropathy was refractory to immunomodulatory treatment, and intensive investigations revealed pancreatic cancer. The patient's neurological deficits improved significantly after the surgery for cancer. Although the combination of AIHA and CIDP has been reported anecdotally, this is the first case of the coexistence of these diseases as paraneoplastic syndromes.

Parathyroid hormone (PTH) is vasoactive, and the endothelium is one of the target tissues of this hormone. Hyperparathyroidism is frequently associated with hypertension. To determine if hyperparathyroidism, which develops particularly in elderly women as a compensatory mechanism to osteoporosis, may be a risk factor for ischemic stroke. Serum PTH levels and bone mineral density (BMD) in 107 elderly patients with ischemic stroke (>or=65 years old) were assessed on the day of onset. The control group consisted of 107 healthy volunteers matched for age and sex. BMD was significantly lower and serum PTH higher in female stroke patients than in control subjects; there was a negative correlation between these two measurements. One-third of the female stroke patients had a serum PTH level higher than the mean + 2 SD of the control subjects (high PTH group), and the interval between menopause and the stroke was significantly longer in the high PTH group than in the normal PTH group. Multiple logistic analyses revealed hypertension and ischemic heart disease were more prevalent in the high PTH group. BMD and PTH were normal in male stroke patients. High serum PTH level may be associated with high incidence of ischemic stroke in women, possibly through the increased incidence of hypertension.

OBJECTIVESA high prevalence of hip and other fractures in elderly patients with Parkinson’s disease has been linked to reduced bone mass arising from a defect of renal synthesis of 1, 25-dihydroxyvitamin D (1, 25-[OH]2D). Treatment with 1α-hydroxyvitamin D3 (1α(OH)D3; an active form of vitamin D) was evaluated for maintaining bone mass and reducing the incidence of hip and other non-vertebral fractures in patients with Parkinson’s disease.METHODSIn a double blind, randomised trial, 86 elderly patients with Parkinson’s disease (mean Hoehn and Yahr stage, 3; mean age 70.6 years) were randomised to receive either 1 μg 1α(OH)D3 daily (treatment group, n=43) or a placebo (n=43) for 18 months. Bone mineral densities in the second metacarpals were determined by computed radiographic densitometry. Serum bone turnover indices were measured serially, and incidence of non-vertebral fractures was recorded.RESULTSBone mineral densities decreased 1.2% in the treatment group compared with 6.7% in the placebo group during 18 months (p<0.0001). At baseline in both groups, the serum concentration of 1, 25-[OH]2D was reduced. Parathyroid hormone was abnormally increased in 15 patients (17%) and correlated negatively with serum 25-hydroxyvitamin D, indicating compensatory hyperparathyroidism. Eight patients sustained fractures (six at the hip and two at other sites) in the placebo group, and one hip fracture occurred among treated patients (odds ratio 9.8; p=0.0028).CONCLUSIONBy increasing serum 1, 25-[OH]2D concentrations, treatment with 1α(OH)D3 can reduce the risk of hip and other non-vertebral fractures in osteoporotic elderly patients with Parkinson’s disease by slowing the loss of bone mineral densities.

The incidence of hepatitis virus type C (HCV) in an area, Futase, of Iizuka city in Chikuho province in the northeastern part of Fukuoka prefecture in Kyushu, Japan, was estimated by screening sera for anti-HCV antibodies. Titers of anti human T-lymphotropic virus type I (HTLV-I) antibodies and hepatitis virus type B surface antigens (HBs) were also determined. The area of the present study is known to have a particularly high prevalence of chronic liver diseases, because coal mining was the key industry until a few decades ago. Also, in the old days it was rather isolated from the neighboring vicinities by surrounding mountains. The subjects of the present survey were 310 patients (117 males and 193 females) with various chronic diseases who visited Futase Social Insurance Hospital during a two year period from 1991 to 1992. Anti-HCV antibodies were detected in the sera of 55 patients, which is an overall positive rate of 18% (26% in male and 14% in female patients). This is extremely high compared to an estimated nationwide average positive rate of 1.6%. Even in 270 patients with normal liver function, the incidence was as high as 10%. The incidences were particularly high in groups of patients aged 40 through 49, 50 through 59 and 60 through 69, ranging from 20 to 23%, while they were as low as 13 and 17% in those aged 70 through 79 and 80 through 89 years, respectively. A high incidence, 57% was estimated for the patients with impaired liver function due to chronic liver diseases, especially in those concomitantly having diabetes mellitus (DM), 91%. The incidence of anti-HCV antibodies was the highest, 100%, in patients having both liver cirrhosis (LC) and DM. This was followed by those having chronic hepatitis (CH) and DM concomitantly and by those with LC alone, 86% each, and by those with CH alone 44%. Furthermore, the genotypes of the HCV in the sera of nine randomly selected carrier patients who had anti-HCV antibodies, even though they had diseases other than hepatic diseases and their liver functions were normal, were examined by the polymerase chain reaction method employing type-specific primers for DNA amplification. As a result, all the HCV strains were type II. On the other hand, there were no apparent differences in the incidences of HTLV-I in the area of the present study and in neighboring provinces of the same prefecture, Fukuoka.(ABSTRACT TRUNCATED AT 400 WORDS)
