Effect of lutein on the acute inflammation-induced c-Fos expression of rat trigeminal spinal nucleus caudalis and C1 dorsal horn neurons.

Although lutein is known to inhibit chronic inflammation, its effect on acute inflammation-induced nociceptive processing in the trigeminal system remains to be determined. The aim of the present study was to investigate whether pretreatment with lutein attenuates acute inflammation-induced sensitization of nociceptive processing in rat spinal trigeminal nucleus caudalis (SpVc) and upper cervical (C1) dorsal horn neurons, via c-Fos immunoreactivity. Mustard oil, a transient receptor potential ankyrin-1 channel agonist, was injected into the whisker pads to induce inflammation. Pretreatment of rats with lutein resulted in significant decreases in the inflammation-induced mean times of face grooming and the thickness of inflammation-induced edema in whisker pads relative to those features in inflamed rats (i.e., rats with no lutein pretreatment). In both the ipsilateral superficial and deep laminae of the SpVc and C1 dorsal horn, there were significantly larger numbers of c-Fos-positive neurons in inflamed rats than in naïve rats, and lutein pretreatment significantly decreased that number relative to inflamed rats. These results suggest that systemic administration of lutein attenuates acute inflammation-induced nocifensive behavior and augmented nociceptive processing of SpVc and C1 neurons that send stimulus localization and intensity information to higher pain centers. These findings support lutein as a potential therapeutic agent for use as an alternative, complementary medicine to attenuate, or even prevent, acute inflammatory pain.

[Palliative rehabilitation of two patients with terminal stage cancer: a visit to patient's home and the provision of advice by a nurse and rehabilitation staff members before discharge--from physical therapist's perspective].

We report two patients with terminal stage cancer who spent some days at their home after a physical therapist, occupational therapist, nurse, and medical social worker all visited the patients' homes and advised the patients' family in regard to the appropriate care before the patients were discharged as a strategy for palliative rehabilitation. Case 1: A patient suffering from terminal stage cancer was bed-ridden because of a pathological fracture of the femur. After palliative rehabilitation, the patient was able to get out of the bed and improved her daily living activity level through physical therapy. She spent some days at home according to the results of the pre-discharge home visit guidance to her family. Case 2: A patient suffering from terminal stage cancer manifested symptoms of fatigue and generalized muscular weakness. After palliative rehabilitation, her muscle strength and physical endurance were improved by physical therapy and adjustment of the bed height. Because she was eager to go home, we took her to her home before being discharged, and she was able to spend a few hours at home. Pre-discharge home visit guidance by a nurse and rehabilitation staff members to the patient' s family in regard to appropriate home care may therefore be a good means of satisfying such patients' desire to see their home once more and thereby improve their quality of life.

Prevalence of post-polio syndrome based on a cross-sectional survey in Kitakyushu, Japan.

OBJECTIVES: To determine the number of polio survivors living in Kitakyushu, Japan, and the prevalence of post-polio syndrome. DESIGN: Cross-sectional survey in Kitakyushu. SUBJECTS/PATIENTS: A total of 342 possible polio survivors were selected from the list of physically disabled persons' certificates administered by the Department of Health and Welfare, Kitakyushu City Government. METHODS: A self-administered questionnaire concerning the diagnosis, paralysis, limitation in daily living, and use of adaptive devices was mailed to the 342 possible polio survivors. RESULTS: By confirmation of the diagnosis, 241 of the 342 turned out to be polio survivors, and the number of polio survivors per population of 100,000 amounted to 24.1. Of the polio survivors, 85% complained of new health problems such as difficulty in climbing stairs, muscle weakness, difficulty in walking, or fatigue. According to Halstead's criteria, 180 polio survivors suffered from post-polio syndrome, and the prevalence of post-polio syndrome in Kitakyushu was 18.0 per population of 100,000. CONCLUSIONS: This survey revealed the number of polio survivors, and the prevalence of post-polio syndrome in Kitakyushu, Japan.
