RESUMEN

AIM: To determine inter-reader analysis and diagnostic performance on digitally reconstructed virtual flexed, abducted, supinated (FABS) imaging from three-dimensional (3D) isotropic elbow magnetic resonance imaging (MRI). MATERIALS AND METHODS: Six musculoskeletal radiologists independently evaluated elbow MRI images with virtual FABS reconstructions, blinded to clinical findings and final diagnoses. Each radiologist recorded a binary result as to whether the tendon was intact and if both heads were visible, along with a categorical value to the type of tear and extent of retraction in centimetres where applicable. Kappa and interclass correlation (ICC) were reported with 95% confidence intervals. Areas under the receiver operating curve (AUC) were reported. RESULTS: FABS reconstructions were obtained successfully in all 48 cases. With respect to tendon intactness, visibility of both heads, and type of tear, the Kappa values were 0.66 (0.53-0.78), 0.24 (0.12-0.37), and 0.55 (0.43-0.66), respectively. For the extent of retraction, the ICC was 0.85 (0.79-0.91) when including the tendons with and without retraction and 0.78 (0.61-0.91) when only including tendons with retraction. For tear versus no tear, AUC values were 0.82 (0.74-0.89) to 0.96 (0.91-1.01). CONCLUSION: Digital reconstruction of FABS positioning is feasible and allows good assessment of individual tendon head tears and retraction with high diagnostic performance.

RESUMEN

BACKGROUND: The aim of the present study was to assess the effect of seven days daidzein pretreatment in cecal ligation and puncture (CLP) model of sepsis. METHODS: We assessed the survival benefit of daidzein and its effect on lung injury in CLP-induced sepsis in mice and determined the bacterial load in peritoneal fluid, blood, and lung homogenates. Tumor necrosis factor α (TNF-α) and corticosterone levels were measured by enzyme-linked immunosorbent assay; relative mRNA expression was estimated by real-time polymerase chain reaction, and standard biochemical techniques were used to measure nitrite level, myeloperoxidase activity, and vascular permeability. RESULTS: Daidzein pretreatment for seven days at a dose of 1 mg/kg body weight subcutaneously increased the survival time of septic mice. Daidzein decreased the bacterial load in peritoneal fluid, blood, and lungs, reduced the tumor necrosis factor α and nitrite level in plasma, and partially suppressed lung injury by reducing vascular permeability and myeloperoxidase activity in septic mice. Further, it restored the relative mRNA expressions of inducible nitric oxide synthase, glucocorticoid receptor α, and glucocorticoid receptor ß genes in septic lungs were restored by daidzein pretreatment. CONCLUSIONS: Daidzein pretreatment for 7 d in sepsis increased the survival time in mice, which may be relate to decrease in bacterial load, anti-inflammatory effect, and protection from lung injury.

RESUMEN

AIM: To characterise the normal motion pattern of the pisotriquetral (PT) joint during wrist extension and flexion, as well as observer performance of measurements using four-dimensional (4D)-computed tomography (CT) acquisitions and double-oblique multiplanar reconstruction (MPR) technique in asymptomatic contralateral joints of patients with unilateral wrist pain. MATERIALS AND METHODS: In this Health Insurance Portability and Accountability Act (HIPAA)-compliant institutional review board-approved study, 4D-CT was performed on the asymptomatic contralateral wrists of 10 patients (mean age: 46 years; M/F: 6/4) for comparison to the symptomatic side. Two independent observers defined the "oblique-sagittal" plane for PT joint measurements. Measurements were obtained for the anteroposterior (AP) interval and craniocaudal (CC) excursion during the extension-flexion arc of wrist motion. RESULTS: The median (interquartile range) of the AP interval was 0.65 mm (0.55-1 mm) in extension, 1.1 mm (0.8-1.82 mm) in the neutral position, and 4.65 mm (2.07-5.87 mm) in flexion. Likewise, the median of the CC excursions in asymptomatic wrists were 0 mm in extension, 0.27 mm (0-0.37 mm) in the neutral position, and 0.28 mm (0.18-0.31 mm) in flexion. The AP interval measurements obtained at wrist flexion were larger than measurements obtained at wrist extension. There was a strong consistency in AP interval difference measurements between the two observers (ICC=0.80; p<0.01); however, CC excursion difference measurements did not reach the significance threshold between the two observers (ICC=0.40; p=0.11). CONCLUSION: PT joint kinematics in asymptomatic wrists demonstrates an increase in AP interval and CC excursion during wrist flexion. MPR techniques provide good interobserver agreements for AP interval measurements. The reported intervals for asymptomatic joints can be used as a reference for asymptomatic wrists.

RESUMEN

The association of amyotrophic lateral sclerosis and pancreatic cancer is rare. Amyotrophic lateral sclerosis is a neurodegenerative disease characterised by pure motor symptoms in the form of progressive muscle weakness and wasting, and can involve the bulbar and respiratory muscles, leading to significant morbidity. Successful surgery for patients with amyotrophic lateral sclerosis for pancreatic cancer has rarely been reported. Surgery in such patients is a dual-edged sword and is decided based on risk-benefit ratio. Patients are at high risk for general anaesthesia because of muscular weakness, increased sensitivity to muscle relaxants and certain anaesthetic drugs. There is a high chance of prolonged postoperative ventilatory support, aspiration pneumonia and pulmonary complications. We report a patient with cancer of the head of the pancreas who underwent successful elective pancreaticoduodenectomy.

RESUMEN

Icariin is a flavonoid from plant belonging to the genus Epimedium, commonly known as Horny goat weed or Yin Yang Huo. The compound possesses multiple biological activities which are associated with the modulation of many signalling pathways, like NF-κB, Erk-p38-JNK, and release of various cytokines and growth factors. The present study determined wound healing potential of icariin in male Wistar rats. Icariin ointment (0%, 0.004%, 0.02%, 0.1% and 0.5%), was applied daily (b.i.d.) for 14 days on ≈ 400 mm2 cutaneous wound in different groups of rats. On day 14 post-wounding, 0.1% and 0.5% icariin treatment significantly (P < 0.01 and P < 0.001, respectively) increased wound contraction, as compared to control. Western blots revealed upregulation of IL-10 and downregulation of NF-κB and TNF-α. Increased expression of CD-31 showed abundance of microvessels in healing tissues after treatment with icariin. The MMP-2 and MMP-9 activities were reduced in icariin treated groups. Masson's trichrome staining revealed relatively better completion of re-epithelisation as well as increased deposition of well organised collagen fibres in the healing tissues compared to control. It is concluded that icariin has potential to accelerate cutaneous wound healing in rats.

RESUMEN

AIMS AND BACKGROUND: Like any other drug, therapeutic use of fresh frozen plasma (FFP) has its own side effects, adverse reactions and risks involved. Overall use of FFP has been on the increase in most tertiary care hospitals. Since the guidelines for FFP use in a clinical setting are not well defined, the present study aims at defining the appropriateness of use of FFP in the light of its risks and benefits as a drug. MATERIALS AND METHODS: We carried out a prospective survey of 821 transfusion orders for 2,915 units of fresh frozen plasma components in our hospital over a 4-month period and recorded indication for transfusion and the number of components requested. RESULTS: Five hundred seventy-three (69.8%) of transfusion requests affecting 2,202 (75.54%) units of FFP were appropriately indicated, while 248 (30.2%) of FFP requests were inappropriately indicated. The majority of fresh frozen plasma requests used were for surgical bleeding (22.77%) because of the deranged coagulation profile before surgery in most of the patients. It was followed by liver disease and transplantation (12.54%). Out of 821 patients, 586 were male and 235 were female. CONCLUSION: Inappropriate requests accounted for 30.2% of the total FFP requests in patients who had normal coagulation parameters. Regular audits, appropriate training of medical staff, conducting regular CMEs are the measures being incorporated in our hospital to rationalize the use of blood components.
