BACKGROUND: This study analyzed the range of motion of the first metatarsophalangeal joint following the chevron procedure with increased stabilization using a modified capsuloperiosteal flap in the treatment of hallux valgus cases. MATERIALS AND METHODS: Forty-three feet of 40 patients were treated with modified chevron osteotomies. The patient selection criteria included failure of conservative treatment, painful deformity, age between 18 and 50, hallux valgus and intermetatarsal angles less than 40 degrees and 17 degrees, respectively, and no osteoarthritic changes of the metatarsophalangeal joint. The passive range of motion of the first metatarsophalangeal joint was compared to the hallux valgus and intermetatarsal angles. RESULTS: The mean age of patients was 30.9 +/- 9.0 (range, 18 to 46) years. The preoperative mean hallux valgus angle was 32.2 (range, 22 to 40 degrees), whereas postoperatively it was 13.1 (range, 3 to 22 degrees). The preoperative mean passive total range of motion, dorsiflexion and plantar flexion were found to be 80.2 (range, 71 to 99 degrees), 66.8 (51 to 86) degrees and 13.4 (range, 7 to 23 degrees), respectively, whereas postoperatively these values were 69.2 (range, 48 to 85 degrees), 58.6 (range, 43 to 75) degrees and 10.8 (range, 1 to 20 degrees). According to Bonney and MacNab subjective scores, the feet were evaluated as follows: 12 as excellent, 26 as good, and 5 as moderate. According to objective scores, the evaluation was as follows: 27 as excellent, 14 as good, 1 as moderate, and 1 as poor. CONCLUSION: We believe that the chevron procedure reinforced by modified capsuloperiosteal flap causes minimal irritation and damage to adjacent soft tissues. Furthermore, we conclude that this method is a benefical means of managing moderate hallux vagus deformities by decreasing the stiffness after surgery. 相似文献

Background: Postoperative vomiting (POV) is a common complication after tonsillectomy. Dexamethasone is known to decrease postsurgical vomiting. In this study, we compared the effects of dexamethasone alone to dexamethasone plus propofol on postoperative vomiting in children undergoing tonsillectomy. Methods: In a randomized double‐blinded study, we evaluated 80 healthy children, aged 4–12 years, who underwent tonsillectomy with or without adenoidectomy. After anesthesia was induced by inhalation of sevoflurane, 0.15 mg·kg?1 dexamethasone and 2 μg·kg?1 fentanyl was administered i.v. to all patients. The patients in the dexamethasone plus propofol group received 1 mg·kg?1 propofol before intubation and continuously after intubation at a rate of 20 μg·kg?1·min?1 until the surgery was completed. Data for postoperative vomiting were grouped into the following time periods: 0–4 and 4–24 h. Data were analyzed using a Student’s t‐test and chi‐squared analysis. Results: The percentage of patients exhibiting a complete response (defined as no retching or vomiting for 24 h) increased from 37.5% in the dexamethasone‐alone group to 75% in the dexamethasone plus propofol group (P = 0.001). Twenty‐two patients (55%) in the dexamethasone‐alone and nine patients (22.5%) in the dexamethasone plus propofol groups experienced vomited during 0–4 h (P = 0.003). Eight patients in the dexamethasone‐alone group and three patients in the dexamethasone plus propofol group received ondansetron as a rescue antiemetic during the postoperative period. Conclusion: For children undergoing tonsillectomy, intraoperative subhypnotic propofol infusion combined with dexamethasone treatment provides a better prophylaxis against postoperative vomiting than does dexamethasone alone. 相似文献

Objectives The aim of this prospective study is to evaluate patients with erectile dysfunction (ED) in terms of coronary artery calcium
(CAC) levels assessed by multidetector computed tomography (MDCT) and to find out if ED severity may predict coronary heart
disease risk.
Patients and method Sixty men with a mean age of 55.7 (41–77) years with ED and 23 men with a mean age of 53.2 (39–76) years without ED, who admitted
to our clinic between January 2005 and December 2005, were included in the study. All patients answered the standard International
Index of Erectile Function (IIEF) forms, and were classified into four groups as mild, moderate, severe ED and no ED. CAC
levels were assessed by MDCT protocol. CAC levels and IIEF scores were analyzed within each group.
Results Pearson correlation test demonstrated significant negative correlation between IIEF score and CAC score (r = −497; P < 0.0001). CAC scores increased significantly with regard to IIEF scores decrease: IIEF 1–10 (n = 18), mean CAC: 557.7; IIEF 11–16 (n = 13), mean CAC: 541.3; IIEF 17–25 (n = 29), mean CAC: 84.6; and IIEF ≥ 26 [n = 23 (Control group)], mean CAC: 10.1. The difference between the mean CAC scores of these four groups was statistically
significant (P < 0.0001). When we took the cut-off value for IIEF score 26 we observed significantly higher CAC scores at the group of IIEF < 26
(mean 325.5 vs 10.1; P < 0.0001).
Conclusion We observed positive correlation with ED severity and CAC levels. Therefore, we think that detection and quantification of
preclinical coronary artery disease by CAC scoring with a non-invasive method might have a great potential for early cardiac
preventive measures. 相似文献

Acute presentation of critical peripheral arterial ischemia in an unstable cardiac patient is a challenge to the surgeon. Coexistence of two entities is usually managed with a staged approach; however, decision to treat which entity first may be difficult clinically. We present a 49-year-old man with acute infrarenal aortic occlusion and cardiac ischemia who was treated with single-stage ascending aorta-bifemoral bypass following saphenous vein grafting to left anterior descending artery. Concomitant coronary and peripheral vascular revascularization is a practical method with a high flow inflow source as ascending aorta. We believe that a single-stage approach may be performed in the unstable patient as presented in this report. 相似文献

Tamoxifen is an anticancer drug that induces oxidative stress and apoptosis via mitochondria-dependent and nitric oxide (NO)-dependent pathways. The present report shows that tamoxifen increases intramitochondrial ionized Ca(2+) concentration and stimulates mitochondrial NO synthase (mtNOS) activity in the mitochondria from rat liver and human breast cancer MCF-7 cells. By stimulating mtNOS, tamoxifen hampers mitochondrial respiration, releases cytochrome c, elevates mitochondrial lipid peroxidation, increases protein tyrosine nitration of certain mitochondrial proteins, decreases the catalytic activity of succinyl-CoA:3-oxoacid CoA-transferase, and induces aggregation of mitochondria. The present report suggests a critical role for mtNOS in apoptosis induced by tamoxifen. 相似文献

Although truncus arteriosus is often treated with low mortality and morbidity rates, truncal valve patency and aortic arch and coronary artery anomalies are factors that can contribute to a worse outcome. In this report, we present our experience with the combination of Rastelli and Norwood procedures for the treatment of Type I truncus arteriosus that was complicated by a hypoplastic aortic arch. 相似文献

Perforation of the gall bladder is a frequent complication during laparoscopic cholecystectomy. Grasping the perforated part of the gall bladder, clip application, or endoscopic loop application are possible solutions to prevent spillage. We propose laparoscopic rubber band application to close the perforated part of the gall bladder as an easy and safe method. We performed rubber band application after iatrogenic perforation of the gall bladder during laparoscopic cholecystectomy in 5 patients. Two-millimeter-wide multiple rubber rings, cut from a 14-Fr Foley catheter, are loaded on a grasper. When a perforation occurred during the dissection of the gall bladder, the hole is grasped with this instrument and 1 of the rings is placed on the gall bladder by the aid of a dissector. Thus, the grasper remained available for traction of the Hartmann's pouch during further dissection of the gall bladder. The rubber bands were placed successfully in all cases. Two perforations occurred in 1 case, and 2 bands were placed with ease. Bile leakage or gall stone spillage did not occur. Operation time was not prolonged. Rubber band ligation of perforation of the gall bladder is a simple, safe, inexpensive, and effective method to prevent spillage of the bile or gallstones in laparoscopic surgery. 相似文献
