A Fast SVM-Based Tongue's Colour Classification Aided by -Means Clustering Identifiers and Colour Attributes as Computer-Assisted Tool for Tongue Diagnosis.

In tongue diagnosis, colour information of tongue body has kept valuable information regarding the state of disease and its correlation with the internal organs. Qualitatively, practitioners may have difficulty in their judgement due to the instable lighting condition and naked eye's ability to capture the exact colour distribution on the tongue especially the tongue with multicolour substance. To overcome this ambiguity, this paper presents a two-stage tongue's multicolour classification based on a support vector machine (SVM) whose support vectors are reduced by our proposed -means clustering identifiers and red colour range for precise tongue colour diagnosis.

An exploratory study of the efficacy and safety of yokukansan for neuropsychiatric symptoms in patients with Parkinson's disease.

The present study examined the efficacy and safety of yokukansan (YKS) in neuropsychiatric symptoms in patients with Parkinson's disease (PD) using the neuropsychiatric inventory (NPI). Twenty-five patients with PD (M:F 14:11; age 72 years) were enrolled and treated with YKS (7.5 g/day) for 12 weeks.

Posterior reversible encephalopathy syndrome complicating intracranial hemorrhage after phenylpropanolamine exposure.

A 57-year-old woman suffered sudden onset of thunderclap headache after exposure to phenylpropanolamine (PPA), and subsequently developed posterior reversible encephalopathy syndrome (PRES) complicated by occipital intracranial hemorrhage (ICH) with cerebral vasoconstriction. PPA is well known to be associated with ICH and vasoconstriction, but this case illustrates the association with PRES. The danger of exposure to PPA and subsequent adverse events is quite low at present, but we must consider the possibility of exposure to medical agents in patients with repeated severe headache who have no organic disorder.

Economy class stroke syndrome after a long drive.

Economy class stroke syndrome is a cardiovascular complication associated with long periods of travel, only a few cases have been reported after long drives, however. The patient, a 62-year-old professional driver, had driven a truck for 2 days with minimal rest. While driving, he noted left foot paresis and numbness, along with geographical disorientation.

Successful treatment with Yokukansan for behavioral and psychological symptoms of Parkinsonian dementia.

Objective: To evaluate the efficacy and safety of Yokukansan, a traditional Chinese herbal medicine, for treating behavioral and psychological symptoms of dementia (BPSD) in patients with Parkinson disease (PD; n=7) and those with PD with dementia (PDD; n=7).

Background: BPSD are often seen in patients with senile dementia and have serious deleterious effects on the lives of patients and caregivers. Recent studies indicate that the traditional Chinese herbal medicine Yokukansan may be safe and beneficial for the treatment of BPSD patients.
