Background: Postoperative fluid collection in the space left behind the dissected hernia sac in laparoscopic herniorraphy puts the surgeon in a dilemma as to whether it is a recurrence or a seroma, and it is not always easily judged only by physical examination (PE). Another important issue is what kind of seroma can be accepted as a complication of surgery. Methods: Thirty patients with unilateral inguinal hernia who had a hernia sac of > 4 cm were operated on with transabdominal preperitoneal hernia repair (TAPP) technique and the collection at the hernia site was followed by PE and superficial ultrasonography (USG) postoperativel . . .y on the first day, first week, first month, and third month. Results: USG detected seroma in 20 patients, while 17 could be noticed by PE on the first postoperative day. At the end of the third month, seromas resolved by 90%, and could only be detected by USG in two patients. Pain or complication rates attributable to seroma in patients were not determined (p > 0.05) in the statistical analyses between the groups. Conclusions: Superficial USG is a beneficial tool in differentiating early recurrence or seroma In patients. It should not be intervened with as a complication until the patient has complaints attributable to seroma Daha fazlası Daha az

A new laparoscopic technique for the placement of a permanent peritoneal dialysis catheter - The preperitoneal tunneling method

Comert, M | Borazan, A | Kulah, E | Ucan, BH

Article | 2005 | SURGICAL ENDOSCOPY AND OTHER INTERVENTIONAL TECHNIQUES19 ( 2 ) , pp.245 - 248

Background: Mechanical outflow obstruction and leakage from the exit site of the catheter are two common complications of continuous ambulatory peritoneal dialysis. To lessen these complications and to achieve immediate use of the catheter, we developed a new laparoscopic technique for catheter placement. Methods: A total of 12 consecutive patients with end-stage renal failure were included in this study between April 2003 and July 2003. The average age of the patients was 42.4 years (range, 37-72). Patients were excluded only if a serious risk for general anesthesia was found. Using two 5-mm ports and a 3.3-mm mini-laparoscope, a p . . .eritoneal dialysis catheter was passed through a preperitoneal tunnel before the tip of the catheter was introduced into the pelvis. Routine peritoneal dialysis was started immediately after the operation while the patients were still in the operating room. Results: The mean operating time was 18.6 min (range, 12-37). There was no operative morbidity. The mean follow-up period was 4.3 months (range, 3-7). No leakage of the dialysate liquid or outflow obstruction was observed during this period. Conclusion: The advantages of this method include accurate placement, preperitoneal fixation, and immediate use of the catheter for routine peritoneal dialysis. We also believe that because of the preperitoneal fixation of the catheter, this technique will decrease outflow obstruction, which usually occurs due to omental wrapping or displacement of the catheter tip Daha fazlası Daha az

Two new mono-nuclear heteroleptic platinum(II) complexes, [Pt(bpy)(iip)](PF6)(2) (1) and [Pt(bpy)(miip)](PF6)(2)center dot 2H(2)O (2) (bpy is 2,2'-bipyridine; iip is 2-(imidazo-4-yl)-1H-imidazo[4,5-f] [1,10] phenanthroline; miip is 2-(1-methylimidazo-2-yl)-1H-imidazo[4,5-f] [1, 10] phenanthroline), have been synthesized and fully characterized by CHN analysis, electrospray ionization and MALDI-TOF mass spectrometry, H-1 NMR, FT-IR (ATR), and UV-Vis spectrophotometer. Cytotoxicity, ability to inhibit DNA transcription and DNAse activity of the complexes were studied. The DNA-binding behaviors of both complexes have also been studied . . .by spectroscopic methods, cyclic voltammetry and viscosity measurements. Both complexes showed cytotoxic properties and 2 was more cytotoxic than 1. DNA transcription was inhibited upon increasing concentrations of both complexes. The complex 2 was found to be a better inhibitor than 1. The same pattern can be seen in the DNAse profile of the complexes. In addition, 2 was found to promote cleavage of pBR322 DNA at a lower concentration than 1. The spectroscopic, electrochemical and viscometric results indicate that both complexes show some degree of binding to DNA in an intercalative mode, resulting in intrinsic binding constants K (b) = 3.55 +/- A 0.6 x 10(4) M-1 and 7.01 +/- A 0.9 x 10(4) M-1 for 1 and 2, respectively. The difference in the DNA-binding affinities of 1 and 2 may presumably be explained by the methylated imidazole nitrogen atom that makes the compound more hydrophobic and gives better intercalative binding ability to DNA's hydrophobic environment Daha fazlası Daha az

The aim of this study was to compare left ventricular (LV) functions by speckle tracking echocardiography (STE) in chronic kidney disease (CKD) patients in various stages and under different renal replacement treatments in order to evaluate possible differences between them. This prospective study included 150 patients with CKD. Renal transplantation patients with glomerular filtration rate greater than 60ml/min/1.73m(2), patients receiving hemodialysis three times a week, and patients in the predialysis stage with glomerular filtration rate less than 30ml/dk/1.73m(2) were assigned into Group 1 (n=50), Group 2 (n=50), and Group 3 (n . . .=50), respectively. LV longitudinal, circumferential, and radial myocardial deformation parameters (strain, strain rate [SR], rotation, twist) were evaluated by STE. Peak systolic longitudinal strain was higher in the transplantation group than the hemodialysis group (-19.93 +/- 3.50 vs-17.47 +/- 3.28%, Daha fazlası Daha az

Peculiar thermodynamic properties of LJ(N) (N=39-55) clusters

Article | 2008 | EUROPEAN PHYSICAL JOURNAL D48 ( 2 ) , pp.221 - 228

The solid-liquid phase transitions of Lennard-Jones clusters LJ(N) (N=39-55) were simulated by a microcanonical molecular dynamics method using Lennard-Jones potential, and their thermodynamic quantities were calculated. The caloric curves of clusters (except N=42) have S-bend. To understand this behaviour, configurational and total entropies were evaluated, and dents on the entropy curves were taken as a sign of negative heat capacity. The heat capacities were evaluated for N=39-55 clusters using configurational entropy data. The potential energy distributions have bimodal behaviour for all clusters in the given range at the meltin . . .g temperature. The distinct melting behaviour of LJ(42) was explained by the topology of the potential energy surface by examining the isomer distributions at phase transitions for LJ(39)-LJ(55). The isomer distributions were found to be a useful way to interpret this behaviour and melting dynamics in general. Melting temperature, latent heat and entropy change upon melting values were reported and are consistent with literature values and values calculated from bulk thermodynamic properties. The dependence of these quantities on the size of the clusters was examined and it is found that latent heat is the key quantity to determine the magic numbers Daha fazlası Daha az

Camurcu, Ismet Yalkin | Yildirim, Timur | Buyuk, Abdul Fettah | Gursu, Sukru Sarper | Bursali, Aysegul | Sahin, Vedat

Article | 2015 | INTERNATIONAL ORTHOPAEDICS39 ( 3 ) , pp.485 - 490

Purpose The aim of this study is to evaluate the efficacy of Tonnis triple pelvic osteotomy in patients with LCP disease. Methods Between 2007 and 2011, Tonnis triple pelvic osteotomy was performed for 43 patients with LCP, in our institute. During the follow-ups of patients with LCP the indications for the surgery were lateralization of the femoral head, insufficient femoral head coverage and subluxation of the femoral head. The mean age of patients at the time of surgery was 9.4 years. Results Before surgical intervention, according to Waldenstrom classification, three patients were in the necrosis stage (7 %), six patients in the . . . fragmentation stage (13.9 %), 16 patients in the re-ossification stage (37.2 %) and 18 patients in the remodeling stage (41.9 %). According to Herring classification, four patients were in group B (9.3 %), one patient in group B/C (2.3 %) and 38 patients in group C (88.4 %). After the operation, patients were evaluated with Stulberg classification, and good outcome (Stulberg I/II) was achieved in 23 patients (53, 5 %), fair outcome (Stulberg III) in 16 patients (37, 2 %) and poor outcome (Stulberg IV/V) was seen in only four patients (9.3 %). The mean value of CEA was 0.37 degrees pre-operatively and in the last follow-ups the mean value of CEA was 23.7 degrees. Conclusions We recommend triple pelvic osteotomy for patients with LCP when conservative methods are not successful. According to our results we believe that Waldenstrom classification is a better option than Herring classification to determine the prognosis of disease after containment surgery Daha fazlası Daha az
