Cystic lymphangioma of small bowel mesentery: a rare case report

Cystic lymphangiomas are rare neoplasms. A 49 year old male patient presented with complaints of lump in abdomen weight loss since 1 month. On examination, patient had a diffuse visible lump above the umbilicus. Ultrasonography of abdomen and pelvis showed a well-defined smoothly marginated anechoic to hyperechoic lesion in midline and left side of abdomen. CECT of abdomen and pelvis was suggestive of pedunculated small bowel leiomyoma desmoid tumor. Exploratory laparotomy with resection of affected loop of jejunum and the supplying mesentery containing the tumor and resection and anastomosis of adjacent small bowel was done. Histologically, the tumor was diagnosed as mesenteric lymphangioma.

A retrospective analysis of neuroendocrine tumour of pancreas: a single institute study

Background: The aim of the work was the clinical characteristics and analysis of preliminary results for surgical treatment of pancreatic neuroendocrine tumors (PNETs). This article deals with the classification of the Pancreatic Neuroendocrine Tumors (PNETs) and discusses their presentation, behaviour, treatment and prognosis.Methods: This was a retrospective study of 70 patients of PNET done over a period of 3 years in The Gujarat Cancer and Research Institute, Ahmedabad. 24 patients who underwent surgical treatment for PNET were further evaluated for surgical outcome, 5yr disease free survival and overall survival.Results: In this study of 70 patients, 61(87.14%) were non-functional. Approximately 77% of PNETs were advanced on presentation (57% metastatic and 20% locally advanced). 20 patients had disease resectable on presentation (11 NF + 9 F). These 20 patients belong to stage I and II of TNM staging system. Only 4 out of 40 metastatic diseases had locally resectable tumor. Of 24 patients who underwent surgery, 12 underwent pancreatico-duodenectomy, 6 underwent enucleation and 6 underwent distal pancreatectomy.Conclusions: PNETs are uncommon tumor of pancreatic origin with presentation more commonly in males than females, usually in the 5th decade. Approximately 77% of patients are advanced or metastatic at presentation. Among those resectable, the Overall Survival for FPNETs and NFPNETs was 90% and 94% respectively and 5yr Disease Free Survival for the same was 100% and 84% respectively.

Outcomes following abdominoperineal resection 6 years retrospective study at a rural district general hospital

Background: A range of surgical techniques are used for perineal wound closure following Abdominoperineal Excision of the Rectum (APER). The aim of this study was to assess the safety and effectiveness of using a biological mesh for perineal wound closure and to compare the outcomes following conventional suture and mesh closure of the perineal wound.Methods: A single-centre retrospective study of a cohort of patients undergoing surgery for low rectal cancer between January 2013 and December 2018. Patient records were analysed for outcomes including perineal complication rates, length of hospital stay and impact of patient factors on complication rates in mesh vs no mesh group.Results: Of the total 43 patients included in the study, 13 (30%) had a conventional perineal closure whereas 30 patients (70%) had a biological mesh reconstruction.  Early perineal wound complications were seen in 21/43 (49%) patients. Of those, 6 (29%) patients were in the no mesh group compared to 15 (71%) patients in the mesh group (p = 0.81). 84% of the patients who received neo adjuvant radiotherapy (NART) developed perineal wound infection. There was no statistically significant difference in the mesh and no mesh groups. None of the patient factors, other than preoperative anaemia, had a statistically significant association with the rate of complications in either of the groups.Conclusions: There was no statistically significant difference in the complication rate between primary and biological mesh closure. Biological mesh is safe for perineal reconstruction following APER

Smart Street Light Management to Reduce Energy Consumption

Smart street light refers to public street light that adapts to movement of pedestrians and vehicles using PIR and IR proximity sensors. The smart streetlight is also referred to as adaptive street lighting, switches OFF when there is no activity but brightens when there is movement. This type of streetlight system is different from traditional or dimmable street lighting that dims at pre-determined times. Solar panels are used to power the lamps. Lamp faults are detected using LDR sensors. Lamp fault and usage can be sent using GSM

Robust estimation of bacterial cell count from optical density

Optical density (OD) is widely used to estimate the density of cells in liquid culture, but cannot be compared between instruments without a standardized calibration protocol and is challenging to relate to actual cell count. We address this with an interlaboratory study comparing three simple, low-cost, and highly accessible OD calibration protocols across 244 laboratories, applied to eight strains of constitutive GFP-expressing E. coli. Based on our results, we recommend calibrating OD to estimated cell count using serial dilution of silica microspheres, which produces highly precise calibration (95.5% of residuals <1.2-fold), is easily assessed for quality control, also assesses instrument effective linear range, and can be combined with fluorescence calibration to obtain units of Molecules of Equivalent Fluorescein (MEFL) per cell, allowing direct comparison and data fusion with flow cytometry measurements: in our study, fluorescence per cell measurements showed only a 1.07-fold mean difference between plate reader and flow cytometry data

Nations within a nation: variations in epidemiological transition across the states of India, 1990–2016 in the Global Burden of Disease Study

18% of the world's population lives in India, and many states of India have populations similar to those of large countries. Action to effectively improve population health in India requires availability of reliable and comprehensive state-level estimates of disease burden and risk factors over time. Such comprehensive estimates have not been available so far for all major diseases and risk factors. Thus, we aimed to estimate the disease burden and risk factors in every state of India as part of the Global Burden of Disease (GBD) Study 2016

Symmetry Analysis and Wave Solutions of the Fisher Equation Using Conformal Fractional Derivatives

In the present article, the time fractional Fisher equation is considered in conformal form to study the application of the Lie classical method and quantitative analysis. The Lie symmetry method has been applied to find the infinitesimal generators and symmetry reductions of the fractional Fisher equation. The obtained reduced form of the equation is solved by the method of G′/G, which gives different forms of solutions. The theory of bifurcation has been utilized in the reduced form to check the stability and nature of critical points by transforming the equations into an autonomous system. Some phase portraits have been drawn at different critical points by the use of maple

Effects of various agitation techniques on sealer penetration in dentinal tubules using CLSM: An in-vitro study

Aim: To compare the effect of ultrasonic, sonic and rotary sealer activation techniques on depth of penetration of sealer in the dentinal tubules. Materials and Methods: Freshly extracted 60 single rooted human permanent mandibuar premolar with mature apex were collected. A size 10 no. K file (Dentsply Maillefer) was introduced into each canal. The irrigation procedure was accomplished by using 2ml of 5.25% NAOCl for each file used. Roots were randomly divided into 3 groups on the basis of sealer activation techniques. The specimens were kept in incubator at 37 degree Centigrade temperature for 2 days. The dentin segments were examined on a confocal microscope in Jawaharlal Nehru University, New Delhi under 4X,10X magnification. Results: A total of 60 teeth were included in the study and they were divided into three groups on the basis of method of agitation of sealer: GROUP I - Lentulospiral, Group II-Ultrasonic endodontic tip, Group III - Endoactivator and obturation was done with gutta percha. Mean percentage and depth of penetration was greatest in Group II i.e. Ultrasonics when used for agitation and statistically significant than Group I lentulospiral and Group III Endoactivator.&nbsp

Three-dimensional finite element analysis of the stress distribution in the endodontically treated maxillary central incisor by glass fiber post and dentin post

Introduction: From the point of dental practice, the restoration of endodontically treated teeth has become an important aspect as it involves a range of treatment options of variable complexity. Restoring teeth with insufficient coronal tooth structure, it is always indicated to use the post to retain a core for definitive restoration. Fiber post has a modulus of elasticity in analogs to dentin structure, thus reducing the stress areas at the dowel dentin interface. However, the only material that can substantiate all these properties can be none other than dentin itself. Materials and Methodology: Three-dimensional (3D) models of the maxillary central incisor were developed incorporating all the nonlinearities. Continuum 3D elements were used in three dimensions. Maxillary central incisor was laser scanned, duplicated with the help of reverse engineering into STL format, and it was converted into 3D model for finite element analysis (FEA). For the model, fixed boundary conditions were applied at the outer bone, while 100 N static vertical occlusal loads were prescribed at 135° on the loading component of the simulated tooth. The stress distribution was evaluated using dentin and fiber post with prescribed materials, loading and boundary conditions in endontically treated teeth by 3D FEA. Results: The analysis for von Misses stress for dentin post showed that the stress in the dentin post at the cervical area was 127 MPa. The displacement in the dentin post was <0.025 mm. Von Misses stress for the fiber post at the cervical area was approximately 182 MPa and the displacement was <0.035 mm. Conclusion: The FEA results showed that the stress in the cervical area of the dentin was more for fiber post when compared to dentin post, and maximum displacement values were less for dentin post in comparison to fiber post
