The aim of this trial is to investigate and compare the effects of electrical stimulation (ES) program and ultrasound (US)
therapy on pain, disability, trunk muscle strength, walking performance, spinal mobility, quality of life (QOL), and depression
in the patients with chronic low back pain (CLBP). A total of 59 patients with definite CLBP were enrolled in this study.
These patients were randomized into three groups. Group 1 (n = 20) was given an ES program and exercises. Group 2 (n = 19) was given an US treatment and exercises. Group 3 (n = 20) was accepted as the control group and was given only exercises. All of the programs were performed 3 days a week, for
6 weeks. The patients were evaluated according to pain, disability, walking performance, endurance, mobility, QOL, depression.
The trunk muscle strength was measured with a hand-held dynamometer. All of the groups showed stastically significant improvements
in pain, disability, muscle strength, endurance, walking performance, mobility, sub-scores of SF 36, and depression when compared
with their initial status. The intergroup comparison showed significant difference in physical function, energy and social
function sub-groups of SF-36, VAS pain, extensor muscle strength, between three groups. This difference was statistically
significant in the groups 1 and 2 compared to the control group. There was also no significant difference between the groups
1 and 2. We observed that US treatment and ES treatment were effective in improving pain, isometric extensor muscle strength,
and QOL in patients with CLBP. 相似文献

Melatonin, a major photoperiod-dependent hormone, regulates circadian rhythms and biological rhythms and acts as a prominent sleep promoter. Symptoms related to hypermelatoninemia have been reported in individuals supplemented with melatonin. However, spontaneous endogenous hypermelatoninemia has not been reported previously. A 6-year-old girl previously diagnosed with Shapiro's syndrome was admitted to our hospital on several occasions during a 1-year period with complaints of altered consciousness, syncope, hypothermia and episodes of sweating. The episodes occurred daily and during sleep and lasted for 1-6 h. During these episodes, she sweated profusely and felt faint and her skin was pale and cool. Other complaints included recurrent abdominal pain, urge incontinence and myopia. She was shown to have hypermelatoninemia (>1,000 pg/ml, normal range 0-150 pg/ml) during these episodes. The duration of her attacks decreased with phototherapy and she was successfully treated with propranolol. To our knowledge, this is the first case of hypermelatoninemia without any detectable organic pathology. We did not determine the exact mechanism of hypermelatoninemia in this patient; however, it might have been related to irregular control of pinealocytes by the suprachiasmatic nucleus or related pathways. Hypermelatoninemia should be considered in patients with spontaneous periodic hypothermia and hyperhidrosis, and also in patients with Shapiro's syndrome. 相似文献

“Faster, better, more” is the conventional benchmark used to define responses of memory T cells when compared with their naïve counterparts. In this issue of the European Journal of Immunology, Mark and Warren Shlomchik and colleagues [Eur. J. Immunol. 2011. 41 : 2782–2792] make the intriguing observation that murine memory CD4+ T‐cell populations enriched for alloreactive precursors are fully capable of rejecting allogeneic skin grafts but yet are incapable of inducing significant graft‐versus‐host disease. These observations add to the emerging concept that memory CD4+ T‐cell development is more nuanced and complex than predicted by conventional models. In particular, the data suggest that it may be just as important to consider what naïve or effector cells have “lost” in their transition to memory. 相似文献

Introduction Chemical and physical effects of cementation cause radiographic and histological changes at bone-cement interface. These changes
can be of interest in the assessment of the residual lesions and subsequent recurrences after local resection and cementation
of local aggressive tumours.
Aim The aim of the study was to evaluate the evolution and determine the stages of the changes that occur at the bone-cement interface
after cementation of cavitary lesions.
Material and methods We operated on 16 hind legs of 8 sheep (Ovies Aries) under general anaesthesia (Xylasin HCl, Ketamin HCl and Forane). A bone
cavity of 12 cm3 was produced by curettage of the distal femoral condyle and was filled with cement. Control radiographs were taken at 2 days;
3, 6 and 12 weeks, and again at 6 months. One sheep each time was killed after second day and sixth month and two sheep each
time after the third, sixth and 12th week and the specimens underwent pathological examination.
Results After the first 3 weeks, a reactive fibrous membrane was detected on pathological examinations. This membrane consisted of
granulation tissue, necrotic bone and bone marrow, which were replaced gradually by fibrous tissue. The radiographic revelation
of this fibrous membrane was a radiolucent zone of 0.5–1.5 mm at 3 weeks. A Sclerotic rim appeared around this radiolucent
zone at 6 weeks. With new bone formation the fibrous membrane disappeared at 3 months. This was seen on radiographs as the
replacement of the radiolucent zone by a sclerotic ring of 0.5–2 mm. This sclerotic ring disappeared at 6 months, when a diffuse
sclerosis and cortical bone thickening was detected on radiographs.
Discussion According to our findings we suggest to consider the pathological processes at the bone-cement interface in 3 phases: (1)
Reactive phase (first 3 weeks); (2) Resorption phase (3–6 weeks), and (3) Formation phase (6 weeks to 6 months). We have distinguished
five different radiographic stages: Stage 1—Early stage with no apparent zone (first 3 weeks); Stage 2—Radiolucent zone (3–6 weeks);
Stage 3—Radiolucent zone with a sclerotic rime (6 weeks to 3 months); Stage 4—sclerotic ring (after 3 months) and Stage 5—Diffuse
cortical thickening (after 6 months). Determining the phases of tissue reaction after cementation and its radiographic revelation
will ease the diagnosis of residual lesions and subsequent recurrences after local resection and cementation of local aggressive
tumors. 相似文献

Background A prospective trial was designed to evaluate the effect of hyperbaric oxygen (HBO) therapy on organ/space sternal surgical
site infections (SSIs) following cardiac surgery that requires sternotomy.
Methods A total of 32 patients who developed postoperative organ/space sternal SSI were enrolled in this study from 1999 through 2005.
All patients were offered HBO therapy. Group 1 included the patients who accepted and were able to undergo HBO therapy (n = 14); group 2 included patients who refused HBO therapy or had contraindications to it (n = 18).
Results The two groups were well matched at baseline with comparable preoperative clinical characteristics and operative factors.
Staphylococcus was the most common pathogen for both groups. The duration of infection was similar in groups 1 and 2 (31.8 7.6 vs. 29.3
5.7 days, respectively, p = 0.357). The infection relapse rate was significantly lower in group 1 (0% vs. 33.3%, p = 0.024). Moreover, the duration of intravenous antibiotic use (47.8 ± 7.4 vs. 67.6 ± 25.1 days, p = 0.036) and total hospital stay (52.6 ± 9.1 vs. 73.6 ± 24.5 days, p = 0.026) were both significantly shorter in group 1.
Conclusion Hyperbaric oxygen is a valuable addition to the armamentarium available to physicians for treating postoperative organ/space
sternal SSI. 相似文献

AIM: Ocular surface changes and ocular symptoms may be encountered in patients with chronic renal failure (CRF) undergoing haemodialysis. The ocular surface changes and its relationship with metabolic control in CRF patients were aimed to be emphasized in this study. METHODS: Thirty-eight CRF patients (75 eyes) undergoing haemodialysis were enrolled. Patients underwent a complete ocular examination together with Schirmer, tear break-up time tests, pachymetric measurements and conjunctival impression cytologies. Blood calcium, phosphate levels and total body volume changes after haemodialysis were recorded. RESULTS: The most common findings were conjunctival calcification with red eye (81.3%) and dry eye (62.7%, according to tear break-up time test) in 75 eyes of 38 patients. Impression cytologies were graded as 0 in 57.3% of eyes and 2-3 in 40% of eyes showing positive correlation with the extent of conjunctival calcification (R = 0.486, P = 0.0001). Serum calcium and phosphate levels were also positively correlated with the degree of conjunctival calcification (R = 0.684, P = 0.0001 and R = 0.428, P = 0.0001, respectively) as well as with the grades of impression cytology (R = 0.587, P = 0.0001 and R = 0.385, P = 0.0001, respectively). Furthermore, the mean corneal thickness decreased significantly (9.31 +/- 26.9 mum) following haemodialysis (Paired t-test, P = 0.002). CONCLUSION: Dry eye and irritational symptoms are major ocular symptoms in CRF patients. Serum calcium and phosphate levels seem to have a prognostic importance for the ocular findings and symptoms in patients with CRF. 相似文献

Isolated spinal accessory nerve palsy after coronary artery bypass graft (CABG) surgery is a rare complication. We report a case of a 52-yr-old male patient who presented with right shoulder weakness, drooping of shoulder, and weakness of forward elevation after CABG. A program of neuromuscular electrical stimulation and exercises was started after the diagnosis of right isolated spinal accessory nerve palsy by physical examination and electromyographic study. Involved muscle function recovered after 6 mos of physical therapy and rehabilitation. This case report suggests that isolated spinal accessory nerve palsy should be considered in cases of shoulder pain or weakness after CABG, and conservative treatment is recommended if palsy develops. 相似文献
