After surgical therapy of diffuse pigmented villonodular synovitis (DPVNS), recurrence is seen in almost half of the patients. The effectiveness of radiosynovectomy (RSV) in preventing recurrence and complaints of DPVNS is well known. Elbow involvement in DPVNS is a very rare condition; therefore, RSV in elbow hasn’t been experienced widely. The aim of this case report is to show the effectiveness of RSV with rhenium-186 (Re-186) sulfide colloid. We applied Re-186 sulfide colloid to the elbow joint of DPVNS patients six weeks after arthroscopic synovectomy. As a result, the patient did not have any complaints, and our findings are compatible with residue or recurrence on magnetic resonance imaging (MRI) in sixth and twentieth month controls after administration. We concluded that Re-186 is an effective adjuvant therapy for the prevention of recurrence and complaints.  相似文献

Purpose

To evaluate the platelet activating factor acetyl hydrolyze (PAF-AH), oxidized low-density lipoprotein (ox-LDL), paraoxonase 1 (PON1), arylesterase (ARE) levels and the effects of metformin and Diane-35 (ethinyl oestradiol + cyproterone acetate) therapies on these parameters and to determine the PON1 polymorphisms among PCOS patients.

Methods

Ninety patients with PCOS, age 30, and body mass index-matched healthy controls were included in the study. Patients were divided into three groups: metformin treatment, Diane-35 treatment and no medication groups. The treatment with metformin or Diane-35 was continued for 6 months and all subjects were evaluated with clinical and biochemical parameters 6 months later. One-way Anova test, t test and non-parametric Mann–Whitney U tests were used for statistical analysis.

Results

PAF-AH and ox-LDL levels were statistically significantly higher in untreated PCOS patients than controls, and they were statistically significantly lower in patients treated with metformin or Diane-35 than untreated PCOS patients. In contrast, there were lower PON1 (not statistically significant) and ARE (statistically significant) levels in untreated PCOS patients than the control group and they significantly increased after metformin and Diane-35 treatments. In PCOS patients serum PON1 levels for QQ, QR and RR phenotypes were statistically significantly lower than the control group.

Conclusion

In patients with PCOS, proatherogenic markers increase. The treatment of PCOS with metformin or Diane-35 had positive effects on lipid profile, increased PON1 level, which is a protector from atherosclerosis and decreased the proatherogenic PAF-AH and ox-LDL levels.  相似文献

Purpose

Our study was undertaken to evaluate the levels of asymmetric dimethyl-arginine (ADMA) in a group of patients affected with polycystic ovary syndrome (PCOS)—under ethinyl estradiol–cyproterone acetate treatment or not—as compared with a group of healthy controls.

Methods

Fifty-eight women with PCOS and 45 patients as control group were included in the study. The 58 women with PCOS were separated into two groups: Group A (n = 29) were treated with an oral contraceptive pill containing 0.035 mg of ethinyl estradiol (EE) and 2 mg of cyproterone acetate (CA) (Diane-35) for 6 months. Group B (n = 29) did not take any drug. Group C (n = 45) was healthy women as control group. Serum levels of ADMA, lipid and glucose metabolism parameters, hormone profile were measured on the sixth month of treatment.

Results

ADMA levels were similar in women with PCOS and controls, whereas ADMA levels significantly decreased after a period of 6 months treatment with EE + CA in women with PCOS. ADMA levels and insulin resistance were decreased with treatment. However, patients with PCOS had significantly higher total cholesterol and Low-density lipoprotein cholesterol (LDL-C) compared to controls, treatment with EE + CA did not provide any improvement on lipid parameters.

Conclusion

Serum ADMA levels and insulin resistance were lower in PCOS group treated with EE + CA than control group.  相似文献

Purpose

To investigate the efficacy of bupivacaine-soaked spongostan in cesarean section wound for postoperative anxiety level, satisfaction and early postpartum depression rate.

Methods

A total of 121 women, American Society of Anesthesiologists physical status I–II, scheduled to undergo general anesthesia and elective cesarean section were recruited and randomized into a study group (n = 61) or a control group (n = 60). In the spongostan group, bupivacaine-soaked spongostan was placed in the cesarean section wound. The control group did not receive spongostan, but only general postoperative care. Maternal health was assessed using a visual analog scale for satisfaction, a visual analog scale for anxiety and the Edinburgh Postpartum Depression Scale for postpartum depression. Also, first breast-feeding time, first mobilization time and opioid consumption were recorded and compared.

Results

The anxiety level of the spongostan group was lower than that of the control group and the difference was statistically significant at all time intervals (1, 6, 12, 18, 24, 30, 36 and 48 h, p < 0.001, respectively). Postpartum depression rate again was significantly lower in the spongostan group both on postoperative day 2 and day 9 (p ≤ 0.01). All satisfaction scores were significantly higher in the spongostan group than in the control group (p < 0.001). Additionally, first breast-feeding and first mobilization times were significantly shorter and opioid consumption was lower in the spongostan group (p < 0.001).

Conclusion

Placement of bupivacaine-soaked spongostan into the cesarean section wound resulted in decreased postoperative anxiety level and postpartum depression rate and increased satisfaction.  相似文献

BACKGROUND

Previous studies have shown that some viral infections may be triggers for autoimmune diseases. The role of viral infections in the etiopathogenesis of pemphigus has also been investigated.

OBJECTIVES

To investigate the relationship between pemphigus and the hepatitis B and C virus infections.

METHODS

This retrospective study included 62 patients with pemphigus and 50 healthy controls of matching ages and genders. The control group included relatives who accompanied the orthopedic patients to the hospital but had no history of systemic and/or autoimmune diseases.

RESULTS

The group of patients with pemphigus was composed of 43 (69.3%) females and 19 (29.7%) males, and the mean age was 48.08 ± 15.38. The hepatitis C virus antibody was negative in all of the patients. Hepatitis B surface antigen (HBsAg), hepatitis B surface antibody (HBsAb), or both, were studied in 44 of the 62 patients. Two (4.3%) of these patients were positive for HBsAg and found to have HBV infection. Fourteen of them were HBsAb positive. Two (4%) of the 50 control subjects showed hepatitis C virus antibody positivity, while only 1 (2%) patient with pemphigus displayed HBsAg positivity. There was no statistically significant difference between the two groups for hepatitis B and C virus infections.

CONCLUSIONS

This study does not support an association between pemphigus and hepatitis B and/or C virus infections.  相似文献

Acute upper respiratory tract infections in children may result in overuse of antibiotics as throat culture cannot be performed in every setting and results cannot be obtained early. A rapid and reliable test might decrease unnecessary antibiotic usage. The purpose of this study was to determine the prevalence of group A beta-hemolytic Streptococcus (GABHS) infections in different pediatric age groups and to assess the diagnostic value of rapid antigen detection test (RADT) for streptococcal pharyngitis. This study was performed in a pediatric outpatient clinic. All children who were admitted with signs and symptoms of acute upper respiratory tract infections were included in the study. Throat culture and RADT were performed and prevalence of GABHS was assessed. Diagnostic value of RADT was determined. This study included 1248 children with a mean age of 6.3+/-3.6 years. There were 655, 518, and 75 children in age groups of 0-6, 7-12 and 13+ years, respectively. The overall prevalence of GABHS was 38.1% (475/1248), as judged by throat culture. The prevalence was highest in the 7-12-year age group (53.9%) and lowest in the 0-6-year age group (25.2%). Considering all patients, RADT gave a sensitivity of 89.7%, specificity of 97.2%. The sensitivity and specificity of RADT were similar in different age groups (p values >0.05). Diagnostic value of RADT is high and can be used safely in populations where streptococcal pharyngitis and its complications such as acute rheumatic fever and acute glomerulonephritis are common.  相似文献

AIM: To compare the results of noncycloplegic photorefraction, cycloplegic photorefraction and cycloplegic refraction in preschool and non-verbal children. METHODS: One hundred and ninety-six eyes of 98 children (50 females, 48 males) were included in the study. Firstly, non-cycloplegic photorefraction was achieved with Plusoptix A09; secondly, cycloplegic photorefraction was carried out with Plusoptix A09 after 10 min cyclopentolate. Finally, 30min after instillation of twice cyclopentolate, cycloplegic refraction was obtained with autorefraction and/or standard retinoscopy. Spheric equivalent, spheric power, cylindric power and cylindrical axis measurements were statistically compared. RESULTS: The mean age was 28.8±18.5mo (range 12-72mo). The differences in spherical equivalent, spheric power and cylindrical power measured by the three methods were found statistically significant (P<0.05). The spherical equivalent and spheric power measured by cycloplegic photorefraction were statistically higher than the measurements of the other methods (P<0.05). The cylindrical power measured by cycloplegic refraction was statistically lower than the measurements of the photorefraction methods (P<0.05). There was no significant difference in cylindrical axis measurements between three methods (P>0.05). CONCLUSION: For the determination of refractive errors in children, the Plusoptix A09 measurements give incorrect results after instillation of cyclopentolate. Additionally, the cylindrical power measured by Plusoptix A09 with or without cycloplegia is higher. However, the non-cycloplegic Plusoptix A09 measures spheric equivalent and spheric power similar to cycloplegic refraction measurements in preschool and non-verbal children.  相似文献
