Prosthetic repair of incarcerated inguinal hernias: is it a reliable method?

Background and aim  

It is generally accepted that most inguinal hernias should be operated on electively using synthetic grafts. However, limited information is available on the usage of these materials in patient with incarcerated and strangulated hernias. The objective of this study is to compare the outcomes of incarcerated inguinal hernia repair with or without graft.     

Pelvic MRI findings of juvenile-onset ankylosing spondylitis

Ankylosing spondylitis (AS) is the most common clinical subgroup of sero-negative spondyloarthropathies. Radiographic and clinical signs of bilateral inflammatory involvement of sacroiliac joints are the gold standard for the diagnosis of juvenile AS. Although radiographic evidence of sacroiliitis is included in the definition, it is not mandatory for the diagnosis of juvenile AS. The aim of this study is to describe pelvic enthesitis–osteitis MRI findings accompanying sacroiliitis in a group of juvenile AS. Eleven patients suffering from low back pain underwent MRI of the pelvis and were enrolled in this retrospective study. The mean duration of symptoms was 12 months. The mean age of the 11 cases in our study was 12.18 years (range, 6–19). There were eight boys and three girls. Anteroposterior radiographs of the pelvis were obtained in all patients. Sacroiliac joint involvement was detected in all of the cases by pelvic MRI. Pathologic signal changes were detected in the pubic symphisis (osteitis pubis) in ten cases, trochanteric bursitis in six cases, coxofemoral joint in five cases, crista iliaca in three cases, and ischion pubis in three cases. There was increased T2 signal intensity in eight of the 11 cases (72.7%) relevant with soft tissue edema/inflammation. This high correlation between sacroiliitis and enthesitis suggests that enthesitis could be an important finding in juvenile AS.     

Antigenotoxic effects of Citrus aurentium L. fruit peel oil on mutagenicity of two alkylating agents and two metals in the Drosophila wing spot test

Antigenotoxic effects of Citrus aurentium L. (Rutaceae) fruit peel oil (CPO) in combination with mutagenic metals and alkylating agents were studied using the wing spot test of D. melanogaster. The four reference mutagens, potassium dichromate (K₂Cr₂O₇), cobalt chloride (CoCl₂), ethylmethanesulfonate (EMS), and N‐ethyl‐N‐nitrosourea (ENU) were clearly genotoxic. CPO alone at doses from 0.1 to 0.5% in Tween 80 was not mutagenic and did not enhance the mutagenic effect of the reference mutagens. However, antigenotoxic effects of CPO were clearly demonstrated in chronic cotreatments with mutagens and oil, by a significant decrease in wing spots induced by all four mutagens. The D. melanogaster wing spot test was found to be a suitable assay for detecting antigenotoxic effects in vivo. Environ. Mol. Mutagen., 2009. © 2009 Wiley‐Liss, Inc.     

Remifentanil versus fentanyl compared in a target-controlled infusion of propofol anesthesia: quality of anesthesia and recovery profile

Purpose  

The aim of the present study was to compare the clinical properties of fentanyl versus remifentanil in a target-controlled infusion (TCI) of propofol anesthesia regimen with bispectral index (BIS) monitoring.
