Diagnostic Significance of Serum Eotaxin-1 Level in Gastric Cancer Patients

Introduction. Gastric cancer is the second cause of cancer-related deaths worldwide. Delayed diagnosis leads to high mortality rates. Eotaxin-1 was originally discovered as an eosinophil-selective chemoattractant and may play a role in a number of chronic inflammatory diseases, cancer, and other gastrointestinal disorders. The aim of this study was to analyse diagnostic and prognostic significance of serum eotaxin-1 (s-eotaxin-1) levels in gastric cancer. Methods. Sixty gastric cancer patients and 69 healthy subjects were included into the study. S-eotaxin-1 levels were compared with clinicopathological features and outcomes in gastric cancer. Results. Serum levels of eotaxin-1 in gastric cancer patients were significantly higher than controls (74.51 ± 16.65 pg/mL versus 16.79 ± 5.52 pg/mL, respectively (P < 0.001)). The s-eotaxin-1 levels did not differ significantly with histopathological grade, tumor-node-metastasis (TNM) stage, tumor localization, lymph node metastases, positive lymph node ratio, size, perineural and perivascular invasion. So there is no relationship found between s-eotaxin-1 level and prognosis. Conclusion. S-eotaxin-1 levels may be used as an easily available biomarker for gastric cancer risk and may alert physicians for early diagnosis. Due to the limited number of patients included in this study, larger cohort studies are warranted to validate the diagnostic value of s-eotaxin-1 level in gastric cancer.     

Unicompartmental knee arthroplasty: Is robotic technology more accurate than conventional technique?

BackgroundRobotic-assisted unicompartmental knee arthroplasty (UKA) with rigid bone fixation "can significantly improve implant placement and leg alignment. The aim of this cadaveric study was to determine whether the use of robotic systems with dynamic bone tracking would provide more accurate UKA implant positioning compared to the conventional manual technique.MethodsThree-dimensional CT-based preoperative plans were created to determine the desired position and orientation for the tibial and femoral components. For each pair of cadaver knees, UKA was performed using traditional instrumentation on the left side and using a haptic robotic system on the right side. Postoperative CT scans were obtained and 3D-to-3D iterative closest point registration was performed. Implant position and orientation were compared to the preoperative plan.ResultsSurgical RMS errors for femoral component placement were within 1.9 mm and 3.7° in all directions of the planned implant position for the robotic group, while RMS errors for the manual group were within 5.4 mm and 10.2°. Average RMS errors for tibial component placement were within 1.4 mm and 5.0° in all directions for the robotic group; while, for the manual group, RMS errors were within 5.7 mm and 19.2°.ConclusionsUKA was more precise using a semiactive robotic system with dynamic bone tracking technology compared to the manual technique.

The effect of hyperglycaemia on haemostasis testing – a volunteer study

We investigated whether the contamination of samples with glucose subsequently tested for haemostasis affected the results, including prothrombin time, activated partial thromboplastin time and fibrinogen concentration. Venous blood was collected from 12 healthy subjects and divided into four aliquots, which were subjected to different degrees of contamination with standard glucose solution (0%, 5%, 10%, 20%). With increasing glucose contamination, prothrombin time increased from mean (SD) 11.0 (0.7) s to 11.2 (0.7) s, 11.5 (0.7) s and 12.2 (0.8) s, all p < 0.001. Activated partial thromboplastin time decreased from 32.3 (0.9) s to 30.9 (0.8) s, 30.8 (0.8) s, and 29.7 (0.7) s, all p < 0.001. Fibrinogen concentration decreased from 3.8 (0.7) g.l^?1 to 3.7 (0.6) g.l^?1, 3.6 (0.6) g.l^?1, and 3.4 (0.6) g.l^?1, all p < 0.001. Bias was clinically meaningful from 5% contamination for activated partial thromboplastin time, 10% contamination for prothrombin time and 20% contamination for fibrinogen concentration. We conclude that if glucose contamination of haemostasis samples is suspected or has occurred, the specimens should not be analysed.     

Epidermoid Cyst—A Rare Mediastinal Mass

Gallstone disease is a common gastrointestinal problem in day-to-day practice. The Old concept that a typical gallstone sufferer is fat, fertile, flatulent female of 50. This is partially true as the disease has been found in women soon after their first delivery who are thin and underweight and in males also. Conditions that favor the formation of cholesterol gallstones are super saturation of bile with cholesterol, kinetically favorable nucleation and presence of cholesterol crystals in the gall bladder long enough to agglomerate into a stone. Recent studies have defined the role of trace elements (Fe, Ca, Zn and Cu) and defective pH in the formation of gallstones. The aim of the study was to correlate iron-deficiency anemia with gallstone disease. To estimate the serum ferritin level as a diagnostic tool of iron deficiency anemia in patients with gallstone disease, this prospective study of 100 patients was conducted over a period of 24 months in the Department of General Surgery, Jaipur Golden Hospital, New Delhi, India. Serum cholesterol, iron and ferritin levels were compared in patients having gallstones and healthy individuals. A low serum iron level is a factor in bile super saturation with respect to cholesterol, leading to gallstone formation.     

Menace of childhood non-accidental traumatic brain injuries: A single unit report

Background:

Childhood traumatic brain injury (TBI) has high rate of mortality and morbidity worldwide. There are dearths of reports from developing countries with large paediatric population on trauma; neurosurgery trauma of nonaccidental origin is not an exemption. This study analysed menace of non-accidental TBI in the paediatric population from our center.

Materials and Methods:

This is a single unit, retrospective study of the epidemiology of non-accidental TBI in children starting from September, 2008 to March, 2014. The management outcomes of the epidemiology of the non-accidental TBI were analysed.

Results:

Total of 109 children age range from 0 (intra-natal) to 16 years with a mean of 5.8 ± 4.6 years (median, 5 years) were enrolled into the study. 34 (31.2%) were domestic violence, 26 (23.9%) street assaults, 16 (14.7%) were due to animal assaults and mishaps, 17 (15.6%) fall from heights. Seven (6.4%) cases of collapsed buildings were also seen during the period. Four (3.7%) industrial accidents and two (1.8%) were self-inflicted injuries. There were also three (2.8%) cases of iatrogenic TBI out of which two infants (1.8%) sustained TBI from cesarean section procedure while one patient (0.9%) under general anaesthesia felt from the operation bed resulting to severe TBI.

Conclusion:

Child abuse, unprotected child labour, parental/care-givers negligence are the main cause of nonaccidental TBI. Human right activists and government agents should be incorporated in curtailing the menace.     

Inhibition of Mild Steel Corrosion in Hydrochloric Acid Solution by New Coumarin

A new coumarin derivative, N,N′-((2E,2′E)-2,2′-(1,4-phenylenebis(methanylylidene))bis(hydrazinecarbonothioyl))bis(2-oxo-2H-chromene-3-carboxamide) PMBH, was synthesized and its chemical structure was elucidated and confirmed using spectroscopic techniques (Infrared spectroscopy IR, Proton nuclear magnetic resonance, ¹H-NMR and carbon-13 nuclear magnetic resonance ¹³C-NMR). The corrosion inhibition effect of PMBH on mild steel in 1.0 M HCl was investigated using corrosion potential (E_CORR), potentiodynamic polarization, electrochemical impedance spectroscopy (EIS), and electrochemical frequency modulation (EFM) measurements. The obtained results indicated that PMBH has promising inhibitive effects on the corrosion of mild steel in 1.0 M HCl across all of the conditions examined. Scanning electron microscopy (SEM) was used to investigate the morphology of the mild steel before and after immersion in 1.0 M HCl solution containing 0.5 mM of PMBH. Surface analysis revealed improvement of corrosion resistance in presence of PMBH.
