Objective
We aimed to examine left–right asymmetry in involved and total neck lymph nodes distribution in patients with bilateral laryngeal cancer in the present study.Methods
Forty-six patients with bilateral laryngeal cancer was included the study. The oncologic database of our otorhinolaryngology department was used. The right and left lymph node with and without involvement by cancer cells counts were retrieved from pathological reports.Results
The numbers of both involved and total neck lymph nodes were significantly higher on right side than on left side for all neck levels in laryngeal malignancies.Conclusions
The results of the present study suggest the existence of a left–right asymmetry in neck lymph node distribution and in the neck lymph node distribution involved by laryngeal cancer cells. The stronger cell-mediated immune activity in the left side of humans may be associated with the blocking of the metastatic invasion of cancer cells from laryngeal malignancies in the left body side. 相似文献72.

In the literature, there have been no studies showing clear results on how radio‐contrast pharmaceuticals would affect intact disc tissue cells. In this context, it was aimed to evaluate the effects of iopromide and gadoxetic acid, frequently used in the discography, on intact lumbar disc tissue in pharmaco‐molecular and histopathological level. Primary cell cultures were prepared from the healthy disc tissue of the patients operated in the neurosurgery clinic. Except for the control group, the cultures were incubated with the indicated radio‐contrast agents. Cell viability, toxicity and proliferation indices were tested at specific time intervals. The cell viability was quantitatively analysed. It was also visually rechecked under a fluorescence microscope with acridine orange/propidium iodide staining. Simultaneously, cell surface morphology was analysed with an inverted light microscope, while haematoxylin and eosin (H&E) staining methodology was used in the histopathological evaluations. The obtained data were evaluated statistically. Unlike the literature, iopromide or gadoxetic acid did not have any adverse effects on the cell viability, proliferation and toxicity (P < 0.05). Although this study reveals that radio‐contrast pharmaceuticals used in the discography, often used in neurosurgical practice, can be safely used, it should be remembered that this study was performed in an in vitro environment. 相似文献

The majority of patients with pancreatic cancer is of advanced disease. Several randomized Phase II and III trials suggest that the combination of gemcitabine and cisplatin (GemCis) response rates were higher than Gemcitabine (Gem) alone, however the trials were not enough powered to indicate a statistically significant prolongation of survival in patients with advanced pancreatic adenocarcinoma. The aim of this retrospective multicenter study is to evaluated the efficiency of Gem alone versus GemCis in patients with locally advanced and/or metastatic pancreatic adenocarcinoma .A total of 406 patients, from fourteen centers were evaluated retrospectively. All patients received Gem or GemCis as first-line treatment between September 2005 to March 2011. Primary end of this study were to evaluate the toxicity, clinical response rate, progression-free survival (PFS) and overall survival (OS) between the arms. There were 156 patients (M: 98, F: 58) in Gem arm and 250 patients (M: 175, F: 75) in the combination arm. Gemcitabin arm patients older than the combination arm ( median 63 vs 57.5, p=0.001). In patients with the combination arm had a higher dose reduction (25.2% vs 11.3%, p=0.001) and dose delay (34% vs 16.8%, p=0.001). Among patients with the combination and Gemcitabin arm gender, diabetes mellitus, performance status, cholestasis, grade, stage did not have a statistically difference (p>0.05). Clinical response rate to the combination arm was higher than the Gem arm (69.0% vs 49.7%, p=0.001). PFS was more favorable in the GemCis arm than Gem alone, but the difference did not attain statistical significance (8.9 vs 6.0, p=0.08). OS was not significantly superior in the GemCis arm (12.0 vs 10.2, p>0.05). Grade III-IV hematologic and nonhematologic toxicity were higher in the combination arm. PFS was more favorable in the GemCis arm than Gem alone, but the difference did not attain statistical significance. OS was not significantly superior in the GemCis arm. 相似文献

Intrauterine ischemia of the limbs is a rare condition involving thrombosis and ischemia of the extremities before birth. The clinical presentation depends on the extremity affected as well as the timing of thrombosis. Very few cases with extremity hypoperfusion and gangrene due to intrauterine thrombosis have been reported in the literature, and therefore there is no consensus on the optimal therapeutic strategy for such cases. Presented here is a case of a newborn with intrauterine brachial arterial thrombosis of the right upper extremity who was successfully treated by a combination of recombinant tissue plasminogen activator, enoxaparin and collagenase application followed by surgery. 相似文献

Objectives
Prolidase is a member of the matrix metalloproteinase family. It plays a major role in collagen turnover, matrix remodeling and cell growth. Nitric oxide (NO) regulates many processes such as collagen synthesis and matrix remodeling. Thus, NO may augment angiogenesis, tumor invasion, and metastasis. The aim of this study was to investigate total antioxidant status (TAS), malondialdehyde (MDA) and NO levels in patients with bladder cancer and to determine their relationship with prolidase activity.Design and methods
Thirty-five patients with bladder cancer and 32 controls were enrolled. Serum TAS, MDA, prolidase activity and NO levels were determined.Results
Serum prolidase activity, NO levels and MDA levels were significantly higher in bladder cancer than controls (all, P < 0.05), while TAS levels were significantly lower (P < 0.05).Conclusions
Our results show that increased prolidase seems to be associated with increased NO levels and oxidative stress along with decreased antioxidant levels in bladder cancer.79.
