Cutaneous Ewing's sarcoma secondary to chemotherapy given for testis tumor: Case report.

Highlights • Tumors developed after radiotherapy or chemotherapy are called secondary tumors.• Secondary tumors are independent of primary tumors, and can arise months and years after the primary tumor.• Early diagnosis and correct treatment could prevent dramatic results.

Preoperative levels of matrix metalloproteinase-7 and -9 and tissue inhibitor of matrix metalloproteinase-1 relation to pathologic parameters in bladder carcinoma patients.

Our aim was to test the hypothesis that preoperative serum levels of matrix metalloproteinase-7 (MMP-7) and -9 (MMP-9) and tissue inhibitor of matrix metalloproteinase (TIMP-1) levels correlate with pathological features. Serum levels of MMP-7, and MMP-9 and TIMP-1 were determined in 90 bladder cancer patients and 40 healthy controls using an enzyme linked immunosorbent assay. Preoperative serum MMP-7 and MMP-9 levels were significantly higher in cancer patients than control groups (p<0.001). In contast, serum TIMP-1 levels were lower (p<0.001). Alteration in MMP-7, and MMP-9, and TIMP-1 production may contribute to tumor angiogenesis and be associated with clinic-pathological features.

Fournier's gangrene: Causes, presentation and survival of sixty-five patients.

Objective: To report our experience with Fournier’s Gangrene (FG) over the past eight years and evaluate the predisposing factors which affect the mortality. Methods: Sixty-five patients who were admitted to emergency surgical unit of our institution presenting with FG between January 2006 and August 2014 were included. The anatomical site of infective gangrene, predisposing factors, etiological factors, and outcomes were retrospectively reviewed. Results: Our cases included 8 women and 57 men. The average age of men was 51±13.9 (range 19-75) and the average age of women was 63±10.5 (range 52-76). Average hospitalization time was 9.2±6.6 days (range 5-25) days. The most frequent comorbid disease was diabetes mellitus and the most frequent etiology was perianal abscess. Colostomy was performed in 11 patients, orchidectomy in two patients, cystostomy in two patients. Notably, all of the 8 (12.3%) patients who died from FG had diabetes and low socioeconomic status. A total of six patients who died required more than one surgical debridement. Conclusions: Fournier’s gangrene is a severe surgical emergency, with a high mortality rate. Low socioeconomic status, diabetes and more than one debridement play a major role in mortality and morbidity.

Isolated renal pelvis rupture secondary to blunt trauma: Case report

Highlights • A case, with isolated renal pelvis rupture due to blunt abdominal trauma.• Clear urine output from the urinary catheter was seen in patient.• Diagnosed a large rupture of renal pelvis by abdominal contrast enhanced CT.• Isolated rupture of the renal pelvis causes delays in the diagnosis of the rupture.• Only a few isolated cases of pelvis rupture with resultant extravasation have been described previously in literature.• Surgical intervention should be warranted in emergency cases.

A Rare Complication Observed during Percutaneous Nephrolithotomy: Foreign Body Migration from the Right Kidney to the Left Lung

Percutaneous nephrolithotomy (PNL) is the first-line treatment in large, multiple stones and lower calyceal stones. Majority of complications associated with PNL are minor and clinically insignificant. It was seen that distal piece (2 cm in size) of ureter catheter observed at pelvis was found at the parenchyma of left lung on the perioperative fluoroscopy in the patient undergoing PNL for right kidney stone. We presented this complication to stress that a foreign body can pass into circulation presumably through venous injury and can migrate to the lung.

Determination of oxidative stress levels and some antioxidant enzyme activities in prostate cancer

Abstract In this study, the antioxidant enzyme activities such as (SOD, GSH, and CAT) and malondialdehyde (MDA) level which is the end product of lipid peroxidation, were determined from the serum samples taken from patients diagnosed with prostate cancer Van Yuzuncu Yıl University Medical Faculty of Educational Research and Training Hospital and İstanbul Bagcilar Education Research Hospital. The SOD, GSH, and CAT activity of patient groups was found significantly lower than the healthy control group in patients with prostate cancer (p < .05). Serum MDA level is found significantly high when compared to control groups. MDA levels increased in patients that suffer prostate cancer disorder. Whereas, firstly antioxidant enzymes activity of SOD, GSH and CAT have been decreased in control groups. Thus, we concluded that the cause of development of prostate cancer may be the result of an imbalance between the antioxidants and oxidative stress. As a result, SOD, CAT, GSH, and MDA may play an important role in the etiopathogenesis of prostate cancer.

Levels of serum trace elements in patients with Peyronie

Abstract Aim: The etiology of the disease of Peyronie is not certainly known. However, penile micro traumas are thought to be important in the pathogenesis of Peyronie’s disease (PD) in genetically predisposed individuals. In this study, we aimed to determine the relationship of some trace element and heavy metals with PD. Material and methods: Thirty Peyronie patients and 26 healthy volunteers were included in the study. In individuals in both groups, levels of serum trace elements (Manganese [Mn], Cu, Cobalt (Co), zinc [Zn], Cd, and iron [Fe]) were determined separately by Atomic Absorption Spectrophotometer method in Yüzüncü Yıl University Central Research Laboratory. Results: Mn, Cu, Zn, and Fe levels in Peyronie patients were statistically significantly lower when compared to the healthy control group (p < .05). Cd and Co levels were similar for both groups but not statistically significant (p > .05). Conclusions: The changes in trace element levels are related to the etiopathogenesis of PD. We think that our study is the first from this aspect.

Our initial experiences in Micro Percutaneous Nephrolithotomy

Böbrek taşı tedavisinde gelişen komplikasyon oranlarını azaltmak için klasik perkütan nefrolitotomi (PNL) prosederünü takiben akses traktı daha küçük olan mini ve ultra-miniPNL yöntemleri geliştirilmiştir (1,2). Mikro-PNL ise daha az invaziv, tek basamakta akses yapılan ve akses traktı daha küçük olan bir işlemdir (3,4). Mikro-PNL’nin en önemli avantajı kanamanın az olması ve komşu organ yaralanması riskinin az olmasıdır (5,6). Mikroperkütan nefrolitotomi, küçük ve orta büyüklükteki seçilmiş olgulara önerilmektedir (7). ÖZET

Oxidative DNA Damage to Sperm Cells and Peripheral Blood Leukocytes in Infertile Men

Background Oxidative DNA damage is associated with male infertility. The aim of this study was to evaluate the oxidative DNA damage of sperm cells and blood leukocytes and to determine the levels of MDA and NO levels in seminal and blood plasma of idiopathic infertile men. Material/Methods The study enrolled 52 patients, including 30 infertile and 22 fertile men. MDA, NO, and 8-OHdG/106dG were estimated using spectrophotometry and high-pressure liquid chromatography (HPLC)-based methods in seminal and blood plasma. The association with the sperm parameters was assessed, particularly sperm counts and motility. Results The mean sperm concentration and sperm motility of the fertile men were significantly higher than that of the infertile men. The mean MDA and NO concentration in the seminal and blood samples of the infertile men were higher than that of fertile men. Also, the mean numbers of sperm cells and leukocytes 8-OHdG/106dG of the infertile men were significantly higher than that of fertile men (p=0.04 and p<0.001, respectively). Sperm motility and sperm count were negatively correlated with leukocyte and sperm cell 8-OHdG/106dG ratio. However, progressive motility was significantly negatively correlated with sperm cell and leukocyte 8-OHdG/106dG ratio (R=−0.357, p=0.026; R=−0.388, p=0.024, respectively). Conclusions Oxidative stress is an important factor in male infertility. Therefore, biochemical detection of 8-OHdG/106dG in sperm cells and blood leukocytes may be an additional tool in the diagnosis of male infertility.

Prevalence of Ureaplasma and Mycoplasma in Infertile Men in Van Region and Effects to Semen Parameters

Aim: The purpose of this study was to assess the prevalence of Ureaplasma urealyticum (UU) and Mycoplasma hominis (MH) in semen cultures of cases with primary infertility in the Van Province, and also to determine the effect of therapy on sperm parameters. Material and Method: The study included 106 individuals divided into three groups: The infertile group (41 cases), the group with lower urinary tract symptoms (33 cases), and the control group (32 cases). The patients in the infertile group had no history of varicocele, testicular torsion, hydrocele, undescended testis, and hormonal disorders. The control group included cases without infertility and lower urinary tract symptoms. The parameters of culture-positive cases in the infertile group were determined before and after therapy. The identification of Mycoplasma species was made using the Biomerieux® Mycoplasma IST 2 (RCS LyonFrance) kit. The sperm count was carried out with the Makler counting chamber (Self Medical Industries, Haifa, Israel). Results: In the infertile group, UU was isolated from 17 and MH was isolated from 3 cases. In the group with lower urinary tract symptoms, UU was isolated from 15 (45.5%) and MH was isolated from 6 (18.8%) cases. In the control group, UU was isolated from 6 (18.8%) cases, but MH was isolated from none of the cases. In the infertile group, the sperm counts in 3 culture-positive cases (15%) and in 10 culture-negative cases (50%) were <15 million each (p<0.025). Prior to therapy, the sperm motility in the culture-positive 14 cases (70%) was lower than 40%, and after therapy, 5 cases (25%) demonstrated a sperm motility of <40%. With therapy, a significant increase in sperm motility was obtained. After therapy of the 20 culture-positive cases (49%), the wives of 4 (20%) patients became pregnant (p<0.025). Discussion: Antibiotherapy in culturepositive cases with undetermined cause of infertility contributes to therapy by positively affecting sperm motility.
