Camptodactyly is a flexion deformity of the proximal interphalangeal joint. Because of unsatisfactory results, treatment is
not recommended for mild deformities, and in severe deformities surgery has been disappointing. A specially designed external
fixator providing gradual distraction was used in a severe case. With this mildly aggressive method, an acceptable result
was obtained.

Oxidative modification of low-density lipoprotein in the artery wall plays a crucial role in the development of atherosclerosis.
This physiopathological mechanism is clearly inhibited by high-density lipoprotein possibly via paraoxonase enzyme activity,
present in high-density lipoprotein. In this study we determined the in vitro susceptibility of low-density lipoprotein to
oxidation and the effect of various factors, such as paraoxonase phenotypes, on this process. Low-density lipoprotein from
healthy volunteers (n=66) was isolated using the precipitant reagent and the oxidation was evaluated by measuring the malonyl dialdehyde and diene
levels. Low-density lipoprotein cholesterol and phospholipid, vitamin E, serum cholesterol, high-density lipoprotein and low-density
lipoprotein cholesterol levels, and erythrocyte antioxidant enzymes were also determined. There was no difference among the
parameters with regard to gender. Low-density lipoprotein samples obtained from subjects with the AA allele were more prone
to oxidation, as observed by their higher stimulated conjugated diene (P=0.041) and thiobarbituric acid-related substance (P=0.042) levels, than samples from subjects with AB or BB alleles. The subjects with the BB allele had higher superoxide dismutase
(P=0.021) and catalase (insignificant increase) activities, while their conjugated diene (P=0.000) levels were lower. In conclusion, our results revealed that the high low-density lipoprotein oxidation is related
to the high low-density lipoprotein cholesterol content and low phospholipid content. The present study demonstrated an increase
in superoxide dismutase and catalase activities, asl well as PON1 activities, in subjects with the BB allele. Since these
enzymes all show activity against low-density lipoprotein oxidation, we propose that future investigations on atherosclerotic
processes should address PON1 polymorphism as well as PON1 and other antioxidant enzymes.

We present a case of large, primary malignant melanoma of the female urethra with poor prognosis in this case report. Malignant melanoma is one of the rare tumors of the female urethra and accounts for 0.2% of all malignant melanoma cases. Large (5.6 cm in diameter), primary malignant melanoma of the female urethra is exceedingly rare. 相似文献

The best management of superficial bladder tumours: Comparing TUR alone versus TUR combined with intravesical chemotherapy modalities? 总被引:1,自引:0,他引:1
To compare retrospectively the recurrence rates of TUR alone versus different intravesical chemotherapy modalities in superficial
bladder cancer cases, 187 patients with stage Ta and T1 bladder tumours were treated with transurethral resection followed by adjuvant intravesical chemotherapy with mitomycin,
BCG or epirubicin or by transurethral resection alone. All patients in this study had historically proven transurethrally
resectable primary, category Ta and T1 transitional cell carcinoma (TCC) of the bladder. Group I included transurethral resection alone, and the other groups included
intravesical mitomycin-C(Group II), BCG (Group III) and epirubicin (Group IV) therapies after transurethral resection. 146
male and 41 female patients (78% male and 22% female patients) in this study were diagnosed as primary TCC bladder tumours.
Only 52 of them were stage Ta and 135 of them were stage T1 bladder tumours. Examining the histological grade of the bladder tumours, 88 (47%) of the patients had grade I, 53 (28%)
had grade IIa, 30 (16%) had grade IIb and remaining 16 (9%) had grade III bladder cancers. The recurrence rates were 25% for
Group I, 23.8% for Group II, 26.2% for Group III and 22.7% for Group IV. These values were given with disregarding the grade
and volume of the bladder tumours. For solitary, less than 3 cm low grade tumours (grade I, IIa) recurrence rates were 16%
for Group I, 15.4% for Group II, 17.8% for Group III, 17.2% for Group IV (p> 0.05). As a result of this retrospective study, for patients with low grade, stage Ta and T1 tumours TUR alone may be the best treatment modality. Although intravesical chemotherapy is effective in decreasing short-term
incidences of tumour recurrence, it has not decreased long-term incidences of tumour recurrence. The high cost and adverse
side effects of intravesical chemotherapy should also be taken into consideration in superficial, single, low grade tumours
of bladder.

Chronic pancreatitis is a rare disease in children and is usually secondary to underlying diseases such as hereditary pancreatitis, cystic fibrosis, hyperlipidemia, prolonged malnutrition, gallstones or anomalies of the biliary-pancreatic duct system. Hereditary pancreatitis is a common cause of chronic pancreatitis in children but is often unrecognized until months or years later. We report here a family with hereditary pancreatitis in which four members are affected. 相似文献

Pilonidal disease has been treated surgically and by various other methods for many years. The most important problem associated with such treatment is recurrence, but cosmetic outcome is another important issue that cannot be ignored. Today, crystallized phenol is recognized as a treatment option associated with good medical and cosmetic outcomes. We hypothesized that the addition of laser depilation to crystallized phenol treatment of pilonidal disease might increase the rate of success, and this study aimed to determine if the hypothesis was true. Patients who were treated with crystallized phenol and 755-nm alexandrite laser depilation were retrospectively analyzed. In total, 42 (31 male and 11 female) patients were treated with crystallized phenol and alexandrite laser depilation and were followed up between January 2009 and January 2012. In all, 38 patients (90.5%) had chronic disease and 4 (9.5%) had recurrent disease. Among the patients, 26 (61.9%) recovered following 1 crystallized phenol treatment, and the remaining patients had complete remission following repeated treatment. Some patients needed multiple treatments, even up to 8 times. None of the patients had a recurrence during a mean 24 months (range, 6–30 months) of follow-up. Whatever method of treatment is used for pilonidal disease, hair cleaning positively affects treatment outcome. The present results support the hypothesis that the addition of laser depilation (which provides more permanent and effective depilation than other methods) to crystallized phenol treatment (a non-radical, minimally invasive method associated with very good cosmetic results) can increase the effectiveness of the treatment and also reduce the recurrence rate of the disease. 相似文献

Extracellular matrix (ECM) remodeling is a major pathophysiological process during post‐myocardial infarction (MI). The activation, differentiation, and proliferation of cardiac fibroblasts to myofibroblasts regulate the expression of ECM proteins. The signaling by bone morphogenetic protein (BMP‐4), an extracellular ligand of the TGF‐β family, has recently been identified as an essential pathway in regulating cardiovascular dysfunctions including myocardial fibrosis. Oligomeric proanthocyanidins (OPC) are well known for their cardioprotective activity. The primary aim of the study was to investigate BMP‐4‐mediated ECM turnover in cardiac fibrosis during isoproterenol‐induced post‐MI and its downregulation by OPC. Myocardial injury was evaluated by assaying serum markers LDH and CK. Oxidative stress and the enzymatic and nonenzymatic antioxidant levels were assessed to support the cardioprotective nature of OPC. The total collagen level was analyzed by measuring hydroxyproline levels. The ISO‐induced group showed a significant decrease in the levels of antioxidants due to severe oxidative stress and increased expression of BMP‐4 which reflects the increased expression of MMP 2 and 9 with a concomitant increase and deposition of fibrillary collagens type I and III responsible for the fibrotic scar formation as evidenced in the histological analysis.BMP‐4 activation, thus, is strongly associated with cardiac fibrosis which was downregulated upon OPC supplementation. This study provides an evidence supporting the antifibrotic effect of OPC via regulation of BMP‐4‐mediated ECM turnover and also substantiates the remarkable antioxidant efficacy of OPC against isoproterenol induced severe oxidative stress and subsequent post‐MI cardiac fibrosis. 相似文献

Objective
To determine the prognostic value of pT3 bladder urothelial carcinoma substaging in patients without lymphatic involvement.Patients and methods
Pathologic and clinical data were reviewed on patients who underwent radical cystectomy for urothelial carcinoma between 1991 and 2010. Of the 460 reviewed patients, 74 patients were diagnosed with pathologic T3No urothelial carcinoma of the bladder. The impact of pathologic substaging (pT3a vs. pT3b) was examined to determine the effect on overall and disease-specific survival.Results
Five years disease-specific and overall survival rates were 46.9 % and 39.6 % for patients with pT3aNo tumor, whereas these ratios were 34.4 and 30.3 %, respectively, for patients with pT3bNo tumor (p > 0.05). Mean disease-specific survival time was 43.94 ± 6.50 months for pT3aNo, while it was 39.01 ± 7.19 months for pT3bNo (p = 0.539). In multivariate cox regression analysis, age (p = 0.459), gender (p = 0.710), urinary diversion type (p = 0.088), and pT3 substaging (p = 0.554) were not noticed as an independent predictive factor for survival.Conclusion
Macroscopic extravesical extension (pT3b) is not associated with a worse outcome than pT3a disease in lymph node-negative cases of bladder urothelial carcinoma. 相似文献10.
