Purpose: A persistent seroma located posterior to a mesh (PPS) remains a little known complication after laparoscopic ventral hernia repair (LVHR). The aim of this large case series was to analyse the prevalence and clinical course as well as identify related factors and independent predictors of PPS.Methods: All 1288 adult patients who underwent a LVHR with an expanded polytetrafluoroethylene mesh (ePTFE) between January 2003 and July 2014 were reviewed. Those who underwent an abdominal computed tomography (CT) scan more than 3 months afterwards (n = 166) were included and their scans were analysed. The primary outcome measure was the prevalence of a PPS and its characteristics. The secondary outcome measures were identification of significantly related factors and independent predictors of PPS.Results: A PPS was observed in 14 of 166 analysed CT scans (8.4%). Eleven patients were symptomatic; conservative treatment (wait-and-see policy) was successful in eight. Three underwent relaparoscopy with removal of a thick neoperitoneum. Several instances of tack and/or mesh detachment were identified on CT scans and during relaparoscopy. Independent predictors were: > 3 trocars (RR 5.0, 95% CI 1.6-15.8) and use of a mesh larger than > 300 cm2 (RR 9.9, 95% CI 1.9-51.2).Conclusions: A PPS is a relatively common complication after LVHR with an ePTFE mesh of usually larger hernias. A "wait-and-see" approach seems justified in most cases. Some require laparoscopic excision of the thick neoperitoneum. A PPS can cause tack and mesh detachment but the clinical consequences are unclear. Recurrences have not been observed in this series. [ABSTRACT FROM AUTHOR]

The article presents a study which examines human papilloma virus (HPV) infection's correlation with colposcopy, cytology, and bioptic tissues' histopathological examination in intraepithelial lesions. The study collects data from year on 1,927 patients with age that ranges from 16-72 years, at the University Clinic of Gynecology and Obstetrics in Belgrade, Serbia. Results show that 272 women out of 1,927 were high-risk types (HR)-HPV positive and 635 showed an abnormal cytological findings.

Purpose: Laparoscopic ventral and incisional hernia repair (LVIHR) carries a risk of adhesion formation and can influence subsequent abdominal operations (SAOs). We performed a retrospective study of findings during reoperations of patients who had previously had an LVIHR by using an expanded polytetrafluoroethylene mesh (DualMesh; WL Gore, Flagstaff, AZ, USA). Methods: The medical records of all 695 patients who had LVIHR at our hospital were reviewed. Patients who underwent SAO for various indications were identified ( n = 72) and analyzed. Results: Seven LVIHR patients (1%) had early SAO (within a few days). In six patients (86%), removal of the mesh was required. Intra-operatively, in all six of these patients with peritonitis, there were no adhesions against the implant identified. Late SAOs (after more than 1 month) were performed in 65 patients (9.4%). Only one patient required acute surgical intervention due to an LVIHR-related adhesion (0.15%). Laparoscopy was performed in 83% and laparotomy in 17% of patients. Adhesions against the implant were present in 83% of patients; in 65%, the adhesions involved omentum only, and in 18%, they involved the bowel. Adhesiolysis was always easy and caused no inadvertent enterotomies. SAOs were devoid of postoperative complications. Conclusions: In this largest series of reoperations after LVIHR, the majority of patients had mild or moderate adhesions against the implant. The specific observations that: (1) no relaparoscopies had to be converted, (2) no inadvertent enterotomies were made during adhesiolysis, and (3) SAOs have practically been devoid of peri- and postoperative complications indicate that SAOs can be safely performed after previous LVIHR with DualMesh.

Nanosize Li-ferrites were synthesised by the thermal decomposition of an appropriate mixture of complex compounds with acetylacetone - (2,4 pentadione) ligands ([M(AA)x]; M=Li and Fe) at 500 °C. The obtained sample is composed of three phases determined by the standard Rietveld procedure: Li0.5Fe2.5O4 (S.G. P4332), Li1.16Fe3O4 (S.G. Fd 3̄ m) and LiFeO2 (S.G. Fm 3̄ m). Cation distribution in nanosize ordered spinel Li0.5Fe2.5O4 deviates from that of the bulk counterpart. Microstructure parameters (crystallite size of ∼23 nm and strain of 3.2526(9)×103) were determined by the Rietveld refinement of the TCH-pV parameters. SEM microphotographs show a particle size of ∼50–60 nm. An order–disorder phase transition in ordered spinel Li0.5Fe2.5O4was studied by DSC measurements and in situ XRPD technique.The temperature of phase transition was found to be 762 °C (DSC) and (±) 7455°C.(XRPD) [ABSTRACT FROM AUTHOR]

Background: We present a unique experience with a patient who had undergone continuous ambulatory peritoneal dialysis (CAPD) after laparoscopic repair of ventral incisional hernia (LRVIH) with an expanded polytetrafluoroethylene (e-PTFE) mesh (DualMesh®; WL Gore) and who later suffered from multiple episodes of CAPD-related peritonitis without any signs of mesh infection. Methods: A 48-year-old man with an open abdominal aortic reconstruction in 1994 for occlusive arterial disease presented with an incisional ventral hernia. He underwent LRVIH using an e-PTFE mesh of 30×20 cm. Results: Postoperatively, he developed renal failure. For various reasons, the only therapeutic option was CAPD. A CAPD-catheter was implanted via laparoscopy, taking care not to compromise the mesh that was completely covered with neoperitoneum. After 3 months of uneventful CAPD, he developed a bacterial peritonitis. Antibiotic treatment failed and the CAPD-catheter was removed. The mesh was left in place and the patient recovered. Later on another CAPD-catheter was implanted via laparoscopy and used for 10 months. Again he developed peritonitis from which he recovered after catheter removal. Mesh was left in place and remained uninfected, probably protected from intra-abdominal bacteria by the neoperitoneum. Conclusions: The risk of secondary infection of an intra-abdominal mesh seems to diminish largely after neoperitonealization of the mesh. CAPD seems possible in a patient with an intra-abdominal mesh when it is covered with neoperitoneum. [ABSTRACT FROM AUTHOR]

Fixation of the prosthesis is one of the critical components of laparoscopic repair of ventral and incisional hernia (LRVIH). The impact of the fixation technique used on operative time has never been analyzed. We compared the duration of the operation according to the fixation technique used in a series of 138 patients with primary umbilical hernia. All patients underwent a straightforward repair by using completely standardized techniques. One hundred and seven patients had mesh fixation with a single crown of tackers (ProTack®, TycoUSS, Norwalk, CT) and eight transabdominal sutures (TAS). Thirty-one patients had mesh fixation with a double crown of tackers (DC) without TAS. There were no significant differences in age, sex, hospital stay, and morbidity between the two groups . Mean operating time for the technique with TAS was 50.6 min compared to 41.4 min for the DC technique. The mean difference in operating time was 9.2 min. This difference was significant ( P = 0.002). During a mean follow-up of 26.4 months, there were no recurrences in the entire series . The difference in operative times between the two operative techniques can be entirely accounted to the difference in the time needed for insertion of eight TAS as compared to the time needed for application of an inner crown of tackers. This strongly indicates that insertion of every single TAS prolongs LRVIH for approximately 1 min. As long as no significant differences between the two fixation techniques are demonstrated on issues of recurrence, complications, and postoperative pain, the time difference we have measured might be an argument in favor of the DC technique, especially when mesh fixation would require a large number of TAS.

The kernel oils ofQuercus roburandQuercus cerriswere obtained by Soxhlet extraction using petroleum ether. Oil yields were found to be 5.2-5.6% and 4.3-4.8% forQ. roburandQ. cerriskernel, respectively (expressed in g per 100 g of dried plant material). The physical and chemical constants, unsaponifiable matter and total fatty acids were determined. The total fatty acid composition of oils was determined by GC in the methyl ester form. Considering the composition and content of fatty acids, the examined kernel oils were very similar. Seven fatty acid components were identified in both oils: palmitic, stearic, arachidic, palmitoleic, oleic, linoleic, and a-linolenic. InQ. roburandQ. cerriskernel oils the principal acids were oleic (44.3% and 43.0%, respectively) and linoleic (37.2% and 32.6%, respectively), followed by a significant amount of palmitic acid.
