Although western medical treatment for heart failure has dramatically improved, limitation still exists where such treatment together with mechanical support fails to manage heart failure. It is unclear whether the addition of Kampo medicine to standard recommended therapy can improve clinical manifestations. To address this issue, we retrospectively evaluated the effects of Mokuboito used in 12 consecutive heart failure patients from April 2013 to April 2015 by analyzing endpoints such as symptoms, BNP concentration, and left ventricular ejection fraction (LVEF). Mokuboito significantly decreased plasma BNP concentration from 796.8 ± 830.8 to 215.6 ± 85.5 pg/ml (p < 0.01) and improved symptoms. There were no significant differences in other parameters including LVEF. In conclusion, the present study suggests that Mokuboito is a useful treatment on top of the standard heart failure medication in severe heart failure patients.

We describe the first case of a patient with Japanese encephalitis suffering from central sleep apnea.
The patient was a 58-year-old man who presented with high fever, semicomatose state, nuchal stiffness,
and incontinence of feces. The patient had complication of severe pneumonia, and was ventilated with
a respirator. After weaning from the respirator, desaturation of oxygen was observed during the night.
Simplified polysomnography revealed a pure central apnea pattern. This case illustrates that Japanese
encephalitis can result in central sleep apnea.

We report a case of unilateral tonic pupil in spinocerebellar ataxia without brainstem atrophy in a 42-
year-old man. On neurological examination, he showed cerebellar symptoms and unilateral tonic pupil.
Deep tendon reflexes were normal except for brisk patellar tendon reflexes. Brain MRI demonstrated
cerebellar atrophy only. There was neither orthostatic hypotension nor bowel and bladder failure. The
right pupil constricted from 5.0 mm to 1.7 mm 60 minutes after 0.125% pilocarpine administration,
whereas the left pupil did not change, remaining at 3.7 mm. Although it is not proven that tonic pupil
is causally related to spinocerebellar ataxia, physicians must remain aware of spinocerebellar ataxia
as a disease that can demonstrate tonic pupil.

STUDY DESIGN: Experimental human study. PURPOSE: To determine whether angiopoietin-like protein 2 (ANGPTL2) is highly expressed in the hyperplastic facet joint (FJ) synovium and whether it activates interleukin-6 (IL-6) secretion in FJ synoviocytes. OVERVIEW OF LITERATURE: Mechanical stress-induced synovitis is partially, but significantly, responsible for degenerative and subsequently osteoarthritic changes in the FJ tissues in patients with lumbar spinal stenosis (LSS). However, the underlying molecular mechanism remains unclear. IL-6 is highly expressed in degenerative FJ synovial tissue and is responsible for local chronic inflammation. ANGPTL2, an inflammatory and mechanically induced mediator, promotes the expression of IL-6 in many cells. METHODS: FJ tissues were harvested from five patients who had undergone lumbar surgery. Immunohistochemistry for ANGPTL2, IL-6, and cell markers was performed in the FJ tissue samples. After cultured synoviocytes from the FJ tissues were subjected to mechanical stress, ANGPTL2 expression and secretion were measured quantitatively using real-time quantitative reverse-transcription–polymerase chain reaction and enzyme-linked immunosorbent assay (ELISA), respectively. Following ANGPTL2 administration in the FJ synoviocytes, anti-nuclear factor-κB (NF-κB) activation was investigated using immunocytochemistry, and IL-6 expression and secretion were assayed quantitatively with or without NF-κB inhibitor. Moreover, we assessed whether ANGPTL2-induced IL-6 modulates leucocyte recruitment in the degenerative process by focusing on the monocyte chemoattractant protein-1 (MCP-1) expression. RESULTS: ANGPTL2 and IL-6 were highly expressed in the hyperplastic FJ synovium samples. ANGPTL2 was co-expressed in both, fibroblast-like and macrophage-like synoviocytes. Further, the expression and secretion of ANGPTL2 in the FJ synoviocytes increased in response to stimulation by mechanical stretching. ANGPTL2 protein promoted the nuclear translocation of NF-κB and induced IL-6 expression and secretion in the FJ synoviocytes. This effect was reversed following treatment with NF-κB inhibitor. Furthermore, ANGPTL2-induced IL-6 upregulated the MCP-1 expression in the FJ synoviocytes. CONCLUSIONS: Mechanical stress-induced ANGPTL2 promotes chronic inflammation in the FJ synovium by activating IL-6 secretion, leading to FJ degeneration and subsequent LSS.

Objective: Cervical dystonia (CD) is a clinically under-recognized symptom occurring at the later- to
end-stages of Parkinson’s disease (PD). The frequency of CD and its influence on prognosis have
not been well studied. Here, we conducted an in-depth examination of CD incidence and impact on
disease progression in later-stage PD. Methods: We retrospectively reviewed the clinical features of 22
deceased patients with sporadic PD treated at a hospital in Japan from 1983 to 2008. Results: The most
common cause of death in PD was pneumonia. CD, in particular retrocollis, was frequent in the later
stages of the disease in elderly patients (9/22, 40.9%). Pneumonia incidence increased sharply in the
later period with CD. There was a positive trend between CD duration and duration of pergolide use.
Conclusion: Analysis revealed that CD increases markedly in late- to end-stage PD, which may be
associated with aspiration pneumonia due to dysphagia. Pathological mechanisms underlying CD might
be influenced by treatments including dopamine agonists. Prevention of CD may increase quality of
life and prolong survival of PD patients.
