Analysis of follow-up data from an outpatient pain management program for refractory chronic pain.

BACKGROUND: Numerous reports indicate that multifaceted pain management programs based on cognitive-behavioral principles are associated with clinically meaningful long-term improvements in chronic pain. However, this has not yet been investigated in Japan. This study investigated the effects of a multifaceted pain management program in Japanese patients with chronic pain, both immediately after the program and 6 months thereafter. METHODS: A total of 96 patients, 37 male and 59 female (mean age 63.8 years) experiencing treatment difficulties and suffering from intractable pain for more than 6 months were enrolled in the study. The programs were conducted with groups of 5-7 patients who met weekly for 9 weeks. Weekly sessions of approximately 2 h in duration incorporating a combination of lectures and exercise were conducted. Several measures related to pain and physical function were assessed at the start of the program, the end of the program, and 6 months after completion of the program. The resulting data were analyzed via Wilcoxon signed-rank test, and 'r' estimated by effect size was also assessed. RESULTS: Of the 96 initial participants, 11 dropped out during the program and 85 completed it. Thereafter, we evaluated 62 subjects at 6 months after the program, while 23 could not be evaluated at that time-point. Pain intensity upon moving, catastrophizing scores, and pain disability scores showed good improvements at the 6-month follow-up, with large efficacy (r > 0.5). Moving capacity and 6-min walking distance also showed good improvements with large efficacy, both at the end of the program and at the 6-month follow-up (r > 0.5). CONCLUSIONS: A multifaceted pain-management program based on cognitive-behavioral principles was effective in Japanese patients with chronic pain, resulting in improved long-term clinical outcomes.

Locomotive syndrome is associated not only with physical capacity but also degree of depression.

BACKGROUND: Reports of locomotive syndrome (LS) have recently been increasing. Although physical performance measures for LS have been well investigated to date, studies including psychiatric assessment are still scarce. Hence, the aim of this study was to investigate both physical and mental parameters in relation to presence and severity of LS using a 25-question geriatric locomotive function scale (GLFS-25) questionnaire. METHODS: 150 elderly people aged over 60 years who were members of our physical-fitness center and displayed well-being were enrolled in this study. Firstly, using the previously determined GLFS-25 cutoff value (=16 points), subjects were divided into two groups accordingly: an LS and non-LS group in order to compare each parameter (age, grip strength, timed-up-and-go test (TUG), one-leg standing with eye open, back muscle and leg muscle strength, degree of depression and cognitive impairment) between the groups using the Mann-Whitney U-test followed by multiple logistic regression analysis. Secondly, a multiple linear regression was conducted to determine which variables showed the strongest correlation with severity of LS. RESULTS: We confirmed 110 people for non-LS (73%) and 40 people for LS using the GLFS-25 cutoff value. Comparative analysis between LS and non-LS revealed significant differences in parameters in age, grip strength, TUG, one-leg standing, back muscle strength and degree of depression (p < 0.006, after Bonferroni correction). Multiple logistic regression revealed that functional decline in grip strength, TUG and one-leg standing and degree of depression were significantly associated with LS. On the other hand, we observed that the significant contributors towards the GLFS-25 score were TUG and degree of depression in multiple linear regression analysis. CONCLUSIONS: The results indicate that LS is associated with not only the capacity of physical performance but also the degree of depression although most participants fell under the criteria of LS.

Vitreous surgery for macular hole in patients with Vogt-Koyanagi-Harada disease.

We describe two patients with Vogt-Koyanagi-Harada (VKH) disease, both in the convalescent stage, who presented with unilateral macular holes together with clinically significant epi-retinal membranes. Vitreo-retinal surgery was performed on the affected eyes and the surgical technique involved a standard three-port vitrectomy, peeling of the epi-retinal and internal limiting membrane (ILM). In both cases the retinae were tamponaded with air resulting in anatomical closure of the macular holes. The histology of the excised membrane was available in one case and this revealed multiple layers of presumed retinal pigment epithelial cells with cytoplasmic processes and intercellular junctions forming a basal lamina attached to the smooth surface of the ILM. Our findings demonstrate that macular holes can develop in patients with VKH but that the hole can be successfully closed with vitreo-retinal surgery. The convalescent stage tends to occur several weeks after the acute stage when the uveitic process has subsided and is characterized by choroidal depigmentation, producing a sunset glow appearance to the ocular fundus. Patients may also demonstrate varying degrees of cutaneous hypopigmentation, poliosis and/or alopecia. Macular holes have also been reported previously in patients during the convalescent stage of VKH and this communication describes the outcome of two patients who underwent vitreo-retinal surgery for this problem.

Unusual posterior hyaloid strand in a young child with optic disc pit maculopathy: intraoperative and histopathological findings.

BACKGROUND: The mechanism responsible for optic disc pit maculopathy is unclear, but abnormal vitreous structures, including the anomalous Cloquet's canal at the optic disc pit, have been suggested as important factors. CASE: We report the intraoperative and ultrastructural findings of an unusual posterior vitreous strand in the eye of an 8-year-old girl with optic disc pit maculopathy. OBSERVATIONS: The patient presented with decreased vision in the left eye. Examination of the left eye revealed a best-corrected visual acuity (VA) of 0.08 and a macular detachment associated with an optic disc pit. Vitrectomy was performed with the adjunctive use of triamcinolone acetonide intraoperatively. The presence of an unusual posterior hyaloid strand tightly attached to the margin of the optic disc pit was noted. An unusual movement of this strand was observed during the surgery. The strand was excised, and fluid-gas exchange was performed using gas tamponade with 20% SF(6). After 12 months, a complete macular reattachment was obtained, with the VA improving to 1.2. Electron microscopic examination of the removed strand revealed abundant thick collagen fibrils with a frame of fine fibrils. CONCLUSION: The unusual posterior vitreous strand connected to the optic disc pit may have contributed to the pathogenesis of maculopathy in this young child.

Changing patterns of intraocular inflammatory disease in Japan.

PURPOSE: We investigated the frequencies and clinical characteristics of Japanese patients with uveitis. METHODS: Records of 189 patients referred from April 1999 to March 2001 were retrospectively reviewed. RESULTS: Fifty-six patients (29.6%) had anterior uveitis, 13 (6.9%) intermediate uveitis, 59 (31.2%) posterior uveitis, 58 (30.7%) panuveitis, and three (1.6%) papillitis. The most common diagnoses were Vogt-Koyanagi-Harada (VKH) disease (10.1%), biopsy-proven or presumed sarcoidosis (9.5%), acute anterior uveitis (7.9%), tuberculosis (6.9%), and Behçet's disease (5.8%). Seventy-three patients (38.6%) were treated with local therapy alone, and 95 patients (50.3%) required systemic therapy. Ocular complications developed in 19.6% of patients, and systemic complications in 2.1%. CONCLUSIONS: These results confirm a continued high frequency of VKH disease and sarcoidosis, but suggest a decreased frequency of Behçet's disease and an increased frequency of tuberculosis. Roughly one-half of the patients required systemic treatment in addition to local therapy, and ocular and/or systemic complications developed in one-fifth of the patients.
