Purpose To determine whether unilateral acute anterior uveitis (AAU) induces ipsilateral changes in the tear fluid proteome. Methods Five patients (25-77 years old) with unilateral AAU were included. Tear fluid samples were obtained using Schirmer's test strips. The healthy eye served as control. Proteins were identified by liquid chromatography tandem mass spectrometry. Results Two hundred forty-two tear fluid sample proteins were identified, of which 75 were present in at least three patients. Nine proteins were at least 1.5-fold increased, whereas eight were at least 1.5-fold decreased in tears from the diseased eye compared with the healthy eye. APOBEC3A was significantly increased (1.43-fold; P = 0.04), whereas TGM2 was significantly decreased (- 1.21-fold; P = 0.03) in tears from the diseased eye relative to the healthy eye. Ingenuity Pathway Analysis identified LXR/RXR (P less then 1.02E-4) as a top canonical pathway. Conclusion Unilateral AAU induced detectable changes in the ipsilateral tear fluid proteome and involvement of the inflammation-associated LXR/RXR pathway.Purpose Multiple intracranial aneurysms (MIA) occur in one-third of patients with intracranial aneurysms (IA), and have been previously associated with an overall worse prognosis. Risk factors for IA formation and rupture in patients with a single IA are well-known. However, risk factors associated with rupture in patients with MIA have been less studied. Methods We performed a retrospective search of patients with MIA identified by computed tomography angiography (CTA) within a 10-year period. Patients with > 1 saccular aneurysm with size ≥ 2.0 mm were included. The location, size, number, and rupture status of the aneurysms were recorded. Patient demographics and cerebrovascular risk factors were obtained from electronic medical records. The primary endpoint of this study was to determine the association of these factors with aneurysmal rupture. The case-fatality rate was evaluated as a secondary outcome. Results Of the 2957 patients with IA in our CTA database, 425 patients were diagnosed with MIA and were therefore included in our study. A total of 1082 aneurysms were identified. Predictors of increased risk of aneurysmal rupture were age (OR 0.98, 95% CI, 0.96-0.99), size ≥ 5 mm (OR 4.4, 95% CI 2.76-7.0); and location in the anterior communicating artery complex (AcomC) (OR 2.62, 95% CI, 1.46-4.72) or posterior communicating artery (PCOM) (OR 2.66, 95% CI, 1.45-4.87). Conclusions Younger age, aneurysm size ≥ 5 mm, and location in the AcomC and PCOM were independently associated with aneurysmal rupture in patients with MIA. Identifying these features could help recognize patients who might benefit from early intervention.Purpose Laugier's hernia is a rare clinical entity compared with a typical femoral hernia. Therefore, the clinical features, radiological findings, and appropriate treatment strategies remain largely unclear. In this study, we present 15 Laugier's hernia cases. Additionally, we review the relevant literature and discuss the clinical features, radiological findings, and appropriate treatment strategies pertaining to Laugier's hernia compared with a typical femoral hernia. Methods Among 1260 hernia patients, we retrospectively enrolled 15 Laugier's hernia patients (1.19%) and 89 femoral hernia patients (7.06%) who underwent herniorrhaphy and compared the demographic characteristics and radiological findings between the two groups. Results Regarding the patient characteristics, a significant difference was observed in the presence of pain (p less then 0.001) and ileus symptoms (p = 0.001). Regarding the hernia characteristics, significant differences were observed in the size of the hernial sac (p = 0.001), contents of the hernial sac (p = 0.003), repositioning of the hernial sac (p less then 0.001), and repair with polypropylene mesh (p less then 0.001). The characteristic multi-detector computed tomography (MDCT) findings enabled the preoperative diagnosis of Laugier's hernia versus conventional femoral hernia. Conclusion Surgeons should be alert to the possibility of atypical femoral hernias while examining femoral hernia or inguinal hernia patients. If Laugier's hernia is suspected, preoperative MDCT is recommended.Purpose Only a small fraction of resectable gallbladder cancer (GBC) patients receive a thorough lymphadenectomy. The aim of this systematic review and meta-analysis was to investigate the effect of lymphadenectomy on survival in GBC surgery. Methods On May 19, 2019, MEDLINE, EMBASE, and the Cochrane Library were searched for English or German articles published since 2002. Studies assessing the effect of lymphadenectomy on survival in GBC surgery were included. Fixed effect and random effects models were used to summarise the hazard ratio (HR). Results Of the 530 identified articles, 18 observational studies (27,570 patients, 10 population-based, 8 cohort studies) were reviewed. In the meta-analysis, lymphadenectomy did not show a significant benefit for T1a tumours (n = 495; HR, 1.37; 95%CI, 0.65-2.86; P = 0.41). Lymphadenectomy showed a significant survival benefit in T1b (n = 1618; HR, 0.69; 95%CI, 0.50-0.94; P = 0.02) and T2 (n = 6204; HR, 0.68; 95%CI, 0.56-0.83; P less then 0.01) tumours. Lymphadenectomy improved survival in the 2 studies assessing T3 tumours (n = 1961). A conclusive analysis was not possible for T4 tumours due to a low case load. Among patients undergoing lymphadenectomy, improved survival was observed in patients with a higher number of resected lymph nodes (HR, 0.57; 95%CI, 0.45-0.71; P less then 0.01). Conclusions Regional lymphadenectomy improves survival in T1b to T3 GBC. A minimum of 6 retrieved lymph nodes are necessary for adequate staging, indicating a thorough lymphadenectomy. Patients with T1a tumours should be evaluated for lymphadenectomy, especially if lymph node metastases are suspected.Purpose Intraoperative detection of intrahepatic lesions can be demanding. The use of preoperative contrast-enhanced magnetic resonance imaging (MRI) or computer tomography (CT) combined with intraoperative ultrasound of the liver is state of the art. Near totally regressed colorectal liver metastases (CRLM) after neoadjuvant chemotherapy or nodules in severely altered liver tissue as steatosis or cirrhosis are often hard to detect during the operative procedure. Especially differentiation between benign atypical nodules and malignant tumors can be very difficult. The intraoperative use of contrast-enhanced ultrasound or intraoperative navigation are helpful tools. However, both methods show relevant limitations. https://www.selleckchem.com/products/gm6001.html The use of intraoperative MRI (ioMRI) can overcome this problem. Relevant structures can be marked within the operative site or immediate control of complete tumor resection can be achieved. This might allow immediate surgical optimization in case of failure. Methods We report the intraoperative application of ioMRI in a case of a 61-year-old male patient suffering from rectal cancer with 10 synchronous bilobar CRLM who was treated stepwise by multimodal treatment and staged hepatectomy.
