We report clinicopathological features of a Japanese family with hereditary motor and sensory neuropathy associated with cerebellar atrophy (HMSNCA). Four affected members from a single generation were examined. They shared common clinical features, including insidious onset in teenage, slowly progressive cerebellar ataxia, amyotrophy, sensory disturbance, and dementia. In addition, all the patients showed hypoalbuminemia and hyperlipidemia and a marked atrophy of the cerebellum on magnetic resonance images. Autopsy of the proband revealed a severe loss of Purkinje cells, degeneration of posterior columns and spinocerebellar tracts of the spinal cord, and a marked loss of myelinated and unmyelinated fibers in the peripheral nerves. We consider that HMSNCA is a distinct form of hereditary multisystem neuronal degeneration.

The characteristics and metabolism of lipoproteins were reviewed. Apolipoproteins has been studied in the fields of neurological diseases as well as hyperlipidemia. A highly significant association between apolipoprotein E (ApoE) epsilone 4 allele and late-onset familial and sporadic Alzheimer's disease (AD) was reported. The recent studies also described the following: (1) late-onset familial AD linked to the proximal long arm of chromosome 19; (2) the presence in the CSF of several proteins, one of which was ApoE, what bound to immobilized amyloid beta-peptide (beta A4) with high avidity; and (3) staining by antisera to ApoE of senile plaques, neurofibrillary tangles, and cerebral vessel amyloid deposits in AD brains. Furthermore, (4) both purified ApoE isomers, ApoE3 and ApoE4, bound to beta A4 synthetic peptide, forming a complex that resisted dissociation by boiling in sodium dodecyl sulfate, but the isomers showed different kinetics in doing so: binding by ApoE4 was observed in minutes, while binding by ApoE3 required hours; and (5) ApoE4 did not bind to beta A4 peptide at pH less than 6.6, while ApoE3 bound to beta A4 peptide from pH7.6 to 4.6. We studied ApoE phenotype expression and the corresponding allele frequencies (epsilon 2, epsilon 3 and epsilon 4) in Japanese patients with late-onset sporadic AD. The frequency of the ApoE epsilon 4 allele was obviously high in AD patients compared with the controls, but it was not different between vascular dementia patients and the controls. These results suggest that ApoE isoforms may play a functional role in the pathophysiology of late-onset familial and sporadic AD and that the isoform-specific difference in beta A4 binding may be involved in forming the AD lesion.

Unsafe and potentially safe herbal therapies are discussed. The use of herbal therapies is on the rise in the United States, but most pharmacists are not adequately prepared educationally to meet patients' requests for information on herbal products. Pharmacists must also cope with an environment in which there is relatively little regulation of herbal therapies by FDA. Many herbs have been identified as unsafe, including borage, calamus, coltsfoot, comfrey, life root, sassafras, chaparral, germander, licorice, and ma huang. Potentially safe herbs include feverfew, garlic, ginkgo, Asian ginseng, saw palmetto, St. John's wort, and valerian. Clinical trials have been used to evaluate feverfew for migraine prevention and rheumatoid arthritis; garlic for hypertension, hyperlipidemia, and infections; ginkgo for circulatory disturbances and dementia; ginseng for fatigue and cancer prevention; and saw palmetto for benign prostatic hyperplasia. Also studied in formal trials have been St. John's wort for depression and valerian for insomnia. The clinical trial results are suggestive of efficacy of some herbal therapies for some conditions. German Commission E, a regulatory body that evaluates the safety and efficacy of herbs on the basis of clinical trials, cases, and other scientific literature, has established indications and dosage recommendations for many herbal therapies. Pharmacists have a responsibility to educate themselves about herbal therapies in order to help patients discern the facts from the fiction, avoid harm, and gain what benefits may be available.

Decision levels of diabetes mellitus and hyperlipidemia in elderly subjects as well as younger subjects should be determined to prevent complications of these diseases such as microvascular and macrovascular diseases. Therefore, prospective follow-up study is necessary to decide the decision levels. In the case of diabetes mellitus, there are some useful studies such as KUMAMOTO STUDY show that strict glycemic control can prevent microvascular diseases, but there are few studies in elderly subjects. However, hypoglycemia causes macrovascular events, and chronic hypoglycemia leads to dementia and apathy. It is generally accepted that the glycemic control level can be milder than that in younger subjects. We suggest that the following decision levels are reasonable for elderly diabetic subjects, 1. FPG > 140-160 mg/dl, 2. PG(2 h) > 200-250 mg/dl, 3. HbA1c > 7-8%. Decision level of hyperlipidemia in elderly subjects should also be determined to prevent cardiovascular disease. It is demonstrated that anti-hyperlipidemic treatment can prevent CHD even in elderly subjects by many prospective studies. Japan Atherosclerosis Society recommend that the decision levels of hyperlipidemia in elderly subjects can be the same as younger subjects. The decision levels indicating diet therapy and medication for risk factor free subjects(category A) are LDL-C > or = 140 and 160 mg/dl, respectively. Those for subjects without CHD but have some risk factors(category B) are LDL-C > or = 120 and 140 mg/dl, respectively. Those for subjects with CHD(category C) are LDL-C > or = 100 and 120 mg/dl, respectively.

Factors accelerating cerebral degenerative changes represent potentially modifiable risks for cognitive decline. Putative risks accelerating subtle cognitive decline and dementia were correlated with repeated measures of cerebral atrophy, CT densitometry, perfusions, and cognitive testing among 224 neurologically and cognitively normative aging volunteers. After age 60, cerebral atrophy, ventricular enlargement, polioaraiosis, and leukoaraiosis geometrically increased as perfusions declined. Risks accelerating perfusional decline, cerebral atrophy, polioaraiosis, and leukoaraiosis were: transient ischemic attacks (TIAs), hypertension, smoking, hyperlipidemia, male gender. At age 71.5 +/- 11.9, subtle cognitive decline began, accelerated by TIAs, hypertension, and heart disease. Leukoaraiosis began before cognitive decline. TIAs, hypertension, and hyperlipidemia correlated with vascular dementias. Excessive cortical perfusional decreases and cerebral atrophy correlated with cognitive decline. Family history of neurodegenerative disease correlated with Alzheimer's disease. We concluded that TIAs, hypertension, hyperlipidemia, smoking, and male gender accelerate cerebral degenerative changes, cognitive decline, and dementia.

The epsilon4 allele of apolipoprotein E (APOE) is reported to be a genetic risk factor of atherosclerosis through hyperlipidemia and late-onset Alzheimer's dementia. A recent report showed that a genetic variant (A -491T) in the promoter region of the APOE gene increases the risk of Alzheimer's disease. In the present study, we examined whether these APOE polymorphisms were genetically involved in essential hypertension. Japanese hypertensives (n=180) with a family history of hypertension and normotensive controls (n=195, sex and age matched with hypertensives) were recruited from the outpatients of Osaka University Hospital, and an informed consent to participate in the study was obtained from each person. APOE polymorphisms were determined using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). The frequencies of the A -491 allele in hypertensives and normotensives were 0.98 and 0.97, respectively, and the TT/-491 genotype was not found in either group. No significant differences between hypertensives and normotensives were observed in allele frequencies in either APOE polymorphism; however, the mean diastolic blood pressure in normotensive subjects with AA/-491 was significantly higher than in the subjects with AT/-491 (p < 0.01). These results suggest that the presence of the APOE promoter polymorphism is not a major risk factor for hypertension but that it does have some minor effect on basal blood pressure variation.

Putative risk factors accelerating mild cognitive decline and dementia were correlated with repeated measures of cerebral atrophy, CT, densitometry, perfusions, and cognitive testing among neurologically and cognitively normative aging volunteers. A total of 224 normative subjects at increased risk for cognitive decline were admitted to the study. Mean entry age was 59.5 +/- 15.8 years. Mean follow-up is 5.8 +/- 3.3 years. At follow-up, 22 developed mild cognitive impairment (41 CCSE >/= -3), 19 became demented-8 with Vascular type (VAD), 11 with Alzheimer's type (DAT)-and 183 remain cognitively unchanged. Cerebral atrophy, tissue densities, and perfusions were measured by Xe-CT. After age 60, cerebral atrophy, ventricular enlargement, and polio- and leuko-araiosis geometrically increased as perfusions declined. Risk factors accelerating perfusional decline, cerebral atrophy, polio-araiosis, and leuko-araiosis were: transient ischemic attacks (TIAs), hypertension, smoking, hyperlipidemia, and male gender. At age 71.5 +/- 11.9, mild cognitive impairment began accelerated by TIAs, hypertension and heart disease. Leuko-araiosis began before cognitive decline. TIAs, hypertension, and hyperlipidemia correlated with VAD. Excessive cortical perfusional decrease, gray and white matter hypodensities, and cerebral atrophy correlate with cognitive decline.

We investigated whether regimen comprehension deteriorated in the elderly patients who did not suffer from obvious dementia. Eligible patients were ambulatory elderly patients who did not show any signs of dementia and could visit our outpatient clinic by themselves. 138 patients (age: 43-89, 75 males and 63 females, underlying diseases: hypertension, hyperlipidemia, arrhythmia etc.) were tested with a regimen comprehension scale (RCS: Jpn J Geriat 1997; 34: 209-214). The differences in scores among individuals increased with age. Scores of 5 or less in the RCS were recorded in 10 out of 69 patients aged 65 or more, but no such scores were recorded in younger patients (p < 0.01). The 60 patients who scored less than full marks were classified into two groups, the T-group (tutored by pharmacists), and a Non Tutored group. RCS was tested again in both groups. Only in the T-group (n = 28), did the second scores increase significantly (from 7.2 +/- 0.9 to 8.6 +/- 2.0 (m +/- SD); p < 0.01) after tutorial by pharmacists. Comparing the 7 patients who obtained an RCS score of 5 or less and age- and gender-matched controls who got full marks, there was no difference in the HDS-R test. These results suggest that even in elderly patients who did not show any signs of dementia, the regimen comprehension deteriorated with age, and tutorials in medication protocols were considered to be effective.

To clarify the characteristics of CADASIL in Japan, we performed clinical and genetic investigations for six patients from 5 Japanese families diagnosed as CADASIL. We identified that the onset of focal neurologic deficits ranged from 38 to 63 years old (mean 49 +/- 9.4 yrs) and the occurrence rates of main neurologic symptoms and signs were 1/6 for migraine, 3/6 for recurrent stroke episodes, 6/6 for dementia, and 4/6 for pseudobulbar palsy. The marked narrowing of retinal arteries were observed in 3/6. The notch 3 mutations were all found in exon 4. Although other several families shared similar phenotype of CADASIL, there were no deposition of granular osmiophilic materials within the basal lamina of smooth muscle cells in the arterioles of biopsied muscle and no mutations in the cording regions of notch 3 gene. We investigated prospectively the incidence of CADASIL and CADASIL-like disease in Kumamoto district from 1999 to 2000. One thousand and thirty four patients with stroke were hospitalized in 6 hospitals which have stroke care unit. Among them, 7 patients fulfilled the criteria that were less than 60 years old, lacunar strokes and/or TIA, presence of a family history, and no risk factors such as hypertension, diabetes mellitus, and hyperlipidemia. One of seven patients was diagnosed as CADASIL by DNA analysis. It was suspected the incidences of CADASIL and CADASIL-like disease were not so rare in Japan.

The aim of the present study was to determine the prevalence of and the host factors for asymptomatic pyuria (ASP) in women with type 2 diabetes. The study included 179 type 2 diabetic women and consecutive 455 non-diabetic women attending as out-patients in 1996. Patients with symptoms of a urinary tract infection were excluded. ASP was defined as the presence of more than 10 leukocytes/high-power field in a random urine sample. Diabetic women more often had ASP than non-diabetic women (27.9 vs. 15.8%, P<0.001). The prevalence of ASP was significantly increased in patients with a duration of diabetes exceeding 15 years (0 approximately 4 years; 20.3%, 5 approximately 9 years; 24.3%, 10 approximately 14 years; 23.8%, and > or =15 years; 46.3%). No differences were evident in HbA(1C) between diabetic patients without ASP and those with ASP. Diabetic women with ASP more often had diabetic retinopathy, neuropathy, nephropathy, cerebrovascular disease, ischemic heart disease, and hyperlipidemia than those without ASP. However, no statistically significant differences were evident in the prevalence of hypertension, constipation, or dementia. As the degree of neuropathy increases, it is accompanied by an increasing prevalence of ASP (none, 21.4%; blunt tendon reflexes, 24.5%; symptomatic, 50.0%; and gangrene, 66.6%). The prevalence of ASP was significantly increased in the patients with proliferative diabetic retinopathy (none, 23.2%; background, 29.4%; pre-proliferative, 18.2%; and proliferative, 50.0%). As the degree of nephropathy increases, it is accompanied by an increasing prevalence of ASP (none, 20.0%; microalbuminuria, 31.9%; macroalbuminuria, 37.0%; and renal failure, 60.0%). Thus, the prevalence of ASP is increased in women with diabetes and increased with longer duration of diabetes but was not affected by glucose control. The incidence of ASP increases significantly as diabetic microangiopathy becomes severer.
