Classification of primary and incisional abdominal wall hernias
A classification for primary and incisional abdominal wall hernias is needed to allow comparison of publications and future studies on these hernias. It is important to know whether the populations described in different studies are comparable.Comparative StudyConsensus Development ConferenceJournal ArticleReviewSCOPUS: ar.jinfo:eu-repo/semantics/publishe

Post-operative benefits of Tisseel®/Tissucol® for mesh fixation in patients undergoing Lichtenstein inguinal hernia repair: secondary results from the TIMELI trial
Pericentral hydroxychloroquine retinopathy in a Caucasian female
Purpose: To report a rare presentation of the pericentral pattern of hydroxychloroquine (HCQ) retinal toxicity in a Caucasian female.
Observations: The patient presented with 20 years of exposure to HCQ, at a daily dose of 5.2mg/kg of actual body weight, and manifested a pericentral-only phenotype of HCQ toxicity, as demonstrated with detailed structural and functional testing.
Conclusions and importance: Although rare, the pericentral pattern of HCQ toxicity may occur in Caucasian patients in the absence of paracentral changes
Randomized, controlled, blinded trial of Tissucol/Tisseel for mesh fixation in patients undergoing Lichtenstein technique for primary inguinal hernia repair: rationale and study design of the TIMELI trial
Randomized controlled trial of Tisseel for mesh fixation in patients undergoing Lichtenstein technique for inguinal hernia repair: the Timeli trial
Randomized, controlled, blinded trial of Tissucol/Tisseel for mesh fixation in patients undergoing Lichtenstein technique for primary inguinal hernia repair: Rationale and study design of the TIMELI trial
Background Complications associated with sutured mesh
fixation following open groin hernia repair have prompted
surgeons to evaluate methods of atraumatic fixation such as
the use of human fibrin glue. Small trials with Tissucol/Tisseel
fibrin glue (Baxter Healthcare, Deerfield, IL, USA)
have shown promising results that warrant further investigation.
Methods TIMELI (Tissucol/Tisseel for MEsh fixation in
LIchtenstein hernia repair) is an international, controlled,
randomized, patient- and evaluator-blinded study that is
comparing mesh fixation with Tissucol or sutures in patients with inguinal hernia. The primary endpoint evaluates
the incidence of disabling complications (chronic pain
and/or numbness and/or groin discomfort) at 12 months
post-surgery.
Results Patient enrolment started in February 2006 and
ended on 19 April 2007, with a total of 325 patients
recruited. Initial results are expected in early 2008.
Conclusions TIMELI is a major international trial that
will provide important information on the efficacy and
safety of Tissucol, compared with sutures, for mesh fixation
in patients undergoing Lichtenstein technique for primary
inguinal hernia repair
Activation of p21-Dependent G1/G2 Arrest in the Absence of DNA Damage as an Antiapoptotic Response to Metabolic Stress
The folate enzyme, FDH (10-formyltetrahydrofolate dehydrogenase, ALDH1L1), a metabolic regulator of proliferation, activates p53-dependent G1 arrest and apoptosis in A549 cells. In the present study, we have demonstrated that FDH-induced apoptosis is abrogated upon siRNA knockdown of the p53 downstream target PUMA. Conversely, siRNA knockdown of p21 eliminated FDH-dependent G1 arrest and resulted in an early apoptosis onset. The acceleration of FDH-dependent apoptosis was even more profound in another cell line, HCT116, in which the p21 gene was silenced through homologous recombination (p21−/− cells). In contrast to A549 cells, FDH caused G2 instead of G1 arrest in HCT116 p21+/+ cells; such an arrest was not seen in p21-deficient (HCT116 p21−/−) cells. In agreement with the cell cycle regulatory function of p21, its strong accumulation in nuclei was seen upon FDH expression. Interestingly, our study did not reveal DNA damage upon FDH elevation in either cell line, as judged by comet assay and the evaluation of histone H2AX phosphorylation. In both A549 and HCT116 cell lines, FDH induced a strong decrease in the intracellular ATP pool (2-fold and 30-fold, respectively), an indication of a decrease in de novo purine biosynthesis as we previously reported. The underlying mechanism for the drop in ATP was the strong decrease in intracellular 10-formyltetrahydrofolate, a substrate in two reactions of the de novo purine pathway. Overall, we have demonstrated that p21 can activate G1 or G2 arrest in the absence of DNA damage as a response to metabolite deprivation. In the case of FDH-related metabolic alterations, this response delays apoptosis but is not sufficient to prevent cell death
