The foot sole is loaded during stance and gait and plantar cutaneous mechanoreceptors sense the local stress distribution. It is not clear whether the perception thresholds of these mechanoreceptors change during the day and how they respond to walking activities. The primary aim of the present study was to investigate diurnal changes of plantar sensitivity. Furthermore, the aim was to find out whether daily changes depend on the individual level of step activity. Twenty-six healthy subjects, 17 women and 9 men, aged 28.6 ± 6.7 years participated in the study. Detection thresholds to light touch were measured in six plantar regions with Semmes-Weinstein monofilaments in the morning, noon and afternoon. Step activity was recorded with a StepWatch™ Activity Monitor and analyzed for three periods (8 a.m.-4 p.m., 8 a.m.-12 p.m., 12 p.m.-4 p.m.). The hallux, the 3rd metatarsal head and the heel showed significantly decreased detection thresholds from 8 a.m. to 4 p.m. (p ≤ 0.05). A fair correlation between the decrease of detection threshold and the total number of steps was found for the 3rd metatarsal head and the heel (p ≤ 0.05). Foot sole sensation appears to improve during the day and seems to be associated with the step activity. This may reflect an improving transfer of afferent information to the central nervous system during the day as well as an adaptation of receptors to gait activity. 相似文献

OBJECTIVES: To determine the incidence and nature of facial asymmetry in patients referred for consideration of aesthetic rhinoplasty and to assess whether objective anthropometric facial measurements correlate with subjective perceptions of asymmetry. DESIGN: Two independent observers measured facial features, including midline to medial and lateral canthi, tragus, ala, and oral commissure distances, in 234 prerhinoplasty surgical photographs. The photographs were rated by 10 independent observers for a global "first impression" of facial symmetry, and the relationship between anthropometric measurement and subjective perception of facial symmetry was explored with logistic regression. RESULTS: Objectively, 97% of patients had significant degrees of facial asymmetry, with the midline to ala distances showing the most variations and the midline to oral commissures showing the least variations. Subjectively, 38% of results were perceived as asymmetrical, with the degree of midline to lateral alar margin asymmetry being an independent predictor of the perception of facial asymmetry on binary logistic regression (P<.003). CONCLUSIONS: A significant correlation was found between the degree of objective facial asymmetry, particularly in anthropometric nasal measurements, and the subjective perception of a face as asymmetrical in patients requesting aesthetic rhinoplasty. This relationship may be a factor in patients who request rhinoplasty and should be explored in this patient group. 相似文献

This study was designed to compare the therapeutic effects of topical clotrimazole and systemic fluconazole in pityriasis versicolor. A double‐blind randomized controlled trial was carried out in the dermatological clinic of Gorgan, northern Iran, between April 2006 and May 2007. All consecutive patients with pityriasis versicolor were included and randomly divided into two groups. In the first group (G1), patients underwent treatment with a single dose of fluconazole capsule (400 mg) and placebo cream. In the second group (G2), patients underwent treatment with clotrimazole cream (twice daily) and placebo capsule. The course of treatment was 2 weeks. All subjects were re‐evaluated 2, 4 and 12 weeks after the end of the therapeutic course. After 2 weeks, the rate of complete resolution of disease was significantly higher in G2 than G1 (49.1% vs 30%). After 4 weeks, 41 patients (81.2%) of G1 and 52 patients (94.9%) of G2 showed complete resolution. After 12 weeks, 46 patients (92%) in G1 and 45 patients (81.8%) in G2 showed complete resolution. Recurrence rate in G1 and G2 were 6% and 18.2%, respectively. No complications were seen in either group. In this study, clinical response at week 4 was greater in the clotrimazole group than the fluconazole group. Recurrence at week 12 after treatment was less with oral fluconazole than clotrimazole cream. So, for better evaluation, more studies need to be done. 相似文献

Introduction
Previous studies have reported that it is difficult to obtain proper anesthesia in mandibular molars with symptomatic irreversible pulpitis, and supplemental injections are usually unavoidable. The aim of the present study was to determine the anesthetic efficacy of articaine in mandibular first molars with symptomatic irreversible pulpitis with 3 injection methods: an inferior alveolar nerve block (IANB), an IANB with an intraligamentary injection, and an IANB with buccal infiltration before initiating the endodontic treatment.Methods
Ninety-six patients (54 women and 42 men) with a diagnosis of symptomatic irreversible pulpitis in mandibular first molars were selected and randomly assigned into 3 groups (n = 32) according to the injection method as follows: group 1, a conventional IANB injection; group 2, an IANB injection, and after profound lip numbness after the IANB (after 15 minutes), buccal infiltration was administered; and group 3, an IANB injection, and after profound lip numbness after the IANB (after 15 minutes), an intraligamentary injection was performed, and after 20 minutes from the IANB, the endodontic treatment was initiated. The anesthetic solution was articaine 4% with 1:100,000 epinephrine. Success was defined as no or mild pain on the basis of the visual analog scale recording upon access cavity preparation or initial instrumentation. Data were statistically analyzed using the chi-square and Mann-Whitney U tests, and P < .05 was set as significant.Results
The success rate for IANBs with an intraligamentary injection was 75%, and for IANBs with a buccal injection, it was 65.6%. For IANBs alone, the success rate was 28.1%.Conclusions
Considering the limitations of the present study, in can be concluded that the success rate of IANBs increased with intraligamentary injections and buccal infiltrations with articaine that were performed before initiating treatment. Also, none of the injection methods showed complete success in anesthesia in all patients. 相似文献40.
