Mushtaq Chalkoo, Shahnawaz Ahangar, Asim Rafiq Laharwal, Aasim Mushtaq Patloo, Abbass Mohd, Shabir Ahmed Dar
Surgical Science (SS) , 2011, DOI: 10.4236/ss.2011.23028
Abstract: Malignant peripheral nerve sheath tumor is a rare soft tissue sarcoma. Breast is an extremely rare location of this lesion and presentation as a breast lump in the absence of pain or previous benign neural tumor is even rarer. We report such a lesion in a 60 year-old female who presented with hard and painless breast lump for 2 years. Histopathology revealed a malignant spindle cell tumor of low grade potential. It was subsequently confirmed to be malignant peripheral nerve sheath tumor (MPNST) on the basis of immunopositivity for vimentin, neurone specific enolase and S-100.

Showkat Majeed Kakroo,Arshad Rashid,Ajaz Ahmad Wani,Zahida Akhtar,Manzoor Ahamad Chalkoo,Asim Rafiq Laharwal
International Journal of Surgical Oncology , 2013, DOI: 10.1155/2013/674965
Abstract: Background. aim of this study was to compare the role of diagnostic laparoscopy and contrast enhanced computed tomography (CECT) of abdomen in the staging of stomach carcinoma. Methods. This was a prospective study conducted in a tertiary care hospital over a period of two years and included 50 patients of endoscopy and biopsy proven stomach carcinoma that were found to be operable on CECT. Diagnostic laparoscopy was performed in all patients before proceeding to a formal laparotomy. Results. Metastasis was detected at diagnostic laparoscopy in 14 (28%) patients. CECT correctly identified the T stage in 22 (61%) patients. Overall accuracy of CECT for T staging was 74% with a a sensitivity of 65% and a specificity of 79%. Laparoscopy correctly identified the T stage in 26 (72%) patients. Overall accuracy of laparoscopy for T staging was 81% with a sensitivity of 76% and specificity of 86%. the most common N stage on CECT was N0 (50%). CECT correctly identified the N stage in 26 (72%) patients. Overall accuracy of CECT for N staging was 86% with a sensitivity of 50% and a specificity of 90%. the most common N stage on laparoscopy was N0 and N2 (42% each). Laparoscopy correctly identified the N stage in 27 (75%) patients. Overall accuracy of Laparoscopy for N staging was 88% with a sensitivity of 53% and specificity of 91%. Conclusion. Laparoscopy is a valuable technique in staging of stomach carcinoma and has an important role in the detection of intra-abdominal metastasis missed by CECT. 1. Introduction Gastric cancer remains one of the most common causes of death from cancer worldwide, especially in our part of the world. In Kashmir, the incidence rates for gastric cancer have been estimated at 36.7/100000 per year in men and 9.9/100000 per annum in women, respectively [1]. As the multidisciplinary management of gastrointestinal cancer has evolved over the last decade, an accurate extent of disease workup has become essential for treatment planning. Even after a thorough radiological workup, many patients with stomach carcinoma are diagnosed as unresectable or metastatic on exploratory laparotomy. For the subgroup of patients who do not require palliation, exploration confers little benefit and may, on the contrary, be associated with significant morbidity and mortality [2]. Since the introduction of contrast enhanced computed tomography (CECT) scan some 30 years back, the staging workup of gastric carcinoma has underwent a boom [3–5]. CECT is used preoperatively primarily to determine the stage and extragastric spread of the carcinoma but has the

GMS German Medical Science , 2013, DOI: 10.3205/000179
Abstract: [english] Background: Surgical procedures advocated for management of residual hepatic hydatid cyst cavity have been a subject of controversy. The aim of this study was to compare omentoplasty (OP) and external tube drainage (ETD).Material and methods: This was a prospective randomized controlled study conducted on radiologically documented cases of hepatic hydatidosis (n=50) in a tertiary care hospital of Kashmir. Patients were divided into two groups; in one group ETD was performed and in another OP was done.Results: Twenty-eight patients were offered ETD and 22 OP. There was no statistically significant difference in mean operative time. The overall complication rate was higher in ETD (42.86%) as compared to OP (22.73%). In ETD group two patients had bile leak and infection of residual cavity each; whereas no such complication was seen in OP. The mean pain scores were elevated in ETD (p<0.0016).The mean hospital stay was more in ETD as compared to OP (p<0.0031). Also time for resumption of activities of daily life was more in ETD (p<0.0026). The recurrence of disease was seen in three patients in ETD as compared to none in OP. Conclusion: Omentoplasty offers a number of advantages over external tube drainage and should remain the preferred option whenever possible. [german] Einleitung: Die chirurgischen Verfahren zur Behandlung von vorhandenen Echinococcus-Zysten in der Leber werden kontrovers beurteilt. Das Ziel dieser Studie war es, die Omentumplastik (OP) mit dem externen Schlauch-Drainageverfahren (ETD) zu vergleichen.Material und Methoden: Eine prospektive randomisierte, kontrollierte Studie an radiologisch nachgewiesenen F llen von Leberechinococcose (n=50) wurde in einem Krankenhaus der Maximalversorgung von Kashmir durchgeführt. Die Patienten wurden in zwei Gruppen eingeteilt: Bei der einen Gruppe wurde die externe Schlauchdrainage (ETD) durchgeführt, die andere Gruppe wurde operativ mit Omentumplastik (OP) behandelt.Ergebnisse: 28 Patienten erhielten das ETD-Verfahren und 22 wurden operativ mit Omentumplastik (OP) behandelt. Die gesamte Komplikationsrate war bei ETD h her (42,86 %), verglichen mit dem OP-Verfahren (22,73 %). In den ETD-Gruppen entstanden bei zwei Patienten Gallenfisteln und Infektionen der Zysten, w hrend in der Kontrollgruppe keine Komplikationen beobachtet wurden. Bei der ETD-Gruppe waren die durchschnittlichen Schmerzskalen (pain scores) erh ht (p<0,0016). Der mittlere Krankenhausaufenthalt war bei ETD l nger als bei dem OP-Verfahren (p<0,0031). Die Zeit bis zur Wiederaufnahme des t glichen Lebens war bei ETD l nger (p<0,
A Step Forward To Component-based Software Cost Estimation in Object-oriented Environment

Computer Science , 2012,
Abstract: Software cost estimation (SCE) of a project is pivotal to the acceptance or rejection of the development of software project. Various SCE techniques have been in practice with their own strengths and limitations. The latest of these is object-oriented one. Currently object-oriented approach for SCE is based on Line of Code (LOC), function points, functions and classes etc. Relatively less attention has been paid to the SCE in component-based software engineering (CBSE). So there is a pressing need to search parameters/variables that have a vital role for the SCE using CBSE which is taken up in this paper. This paper further looks at level of significance of all the parameters/variables thus searched. The time is being used as an independent variable because time is a parameter which is almost, all previous in one. Therefore this approach may be in a way an alternate of all previous approaches. Infact the underlying research ultimately may lead towards SCE of complex systems, using CBSE, in a scientific, systematic and comprehensive way.
A New Teaching Model For The Subject Of Software Project Management
M. Rizwan Jameel Qureshi,Muhammad Rafiq Asim,Muhammad Nadeem,Asif Mehmood
Computer Science , 2012,
Abstract: Software (SW) development is a very tough task which requires a skilled project leader for its success. If the project leader is not skilled enough then project may fail. In the real world of SW engineering 65% of the SW projects fail to meet their objectives as in [1]. The main reason is lack of training of the project mangers. This extreme ratio of failure can be reduced by teaching SW project management (SPM) to the future project managers in the practical manner, so that they may be skillful enough to handle the project in a better way. This paper intends to propose a model to be used to teach SPM to the student of SW engineering to reduce the failure rate of projects.
The Influence of LOS Components on the Statistical Properties of the Capacity of Amplify-and-Forward Channels  [PDF]
Gulzaib RAFIQ, Matthias PATZOLD
Wireless Sensor Network (WSN) , 2009, DOI: 10.4236/wsn.2009.11002
Abstract: Amplify-and-forward channels in cooperative networks provide a promising improvement in the network coverage and system throughput. Under line-of-sight (LOS) propagation conditions in such cooperative networks, the overall fading channel can be modeled by a double Rice process. In this article, we have stud-ied the statistical properties of the capacity of double Rice fading channels. We have derived the analytical expressions for the probability density function (PDF), cumulative distribution function (CDF), level- crossing rate (LCR), and average duration of fades (ADF) of the channel capacity. The obtained results are studied for different values of the amplitudes of the LOS components in the two links of double Rice fading channels. It has been observed that the statistics of the capacity of double Rice fading channels are quite dif-ferent from those of double Rayleigh and classical Rice fading channels. Moreover, the presence of an LOS component in any of the two links increases the mean channel capacity and the LCR of the channel capacity. The validity of the theoretical results is confirmed by simulations. The results presented in this article can be very useful for communication system designers to optimize the performance of cooperative networks in wireless communication systems.

Asim Ahmad, Winston Tan
Open Journal of Urology (OJU) , 2012, DOI: 10.4236/oju.2012.223037
Abstract: Castrate resistant metastatic prostate cancer remains a fatal disease. Through preclinical studies and clinical trials, a multitude of options have been made available to prolong the life of these patients, as well as improve quality of life. First line treatment options following tumor progression after androgen deprivation therapy include Provenge and docetaxel. Several options are available as second line treatment, including cabazitaxel, abiraterone, and enzalutamide. Many drugs currently being studied are very promising, such as alpharadin. Here we review treatment options for patients suffering from disease progression after androgen deprivation therapy, and offer a review of the current available options for the clinician.

Int'l J. of Communications, Network and System Sciences (IJCNS) , 2013, DOI: 10.4236/ijcns.2013.65025
Abstract:

In this paper, I described the methods that I used for the creation of Xlets, which are Java applets that are developed for the IDTV environment; and the methods for online data retrieval and processing that I utilized in these Xlets. The themes that I chose for the Xlets of the IDTV applications are Earthquake and Tsunami Early Warning; Recent Seismic Activity Report; and Emergency Services. The online data regarding the Recent Seismic Activity Report application are provided by the Kandilli Observatory and Earthquake Research Institute (KOERI) of Bogazici University in Istanbul; while the online data for the Earthquake and Tsunami Early Warning and the Emergency Services applications are provided by the Godoro website which I used for storing (and retrieving by the Xlets) the earthquake and tsunami early warning simulation data, and the DVB network subscriber data (such as name and address information) for utilizing in the Emergency Services (Police, Ambulance and Fire Department) application. I have focused on the methodologies to use digital television as an efficient medium to convey timely and useful information regarding seismic warning data to the public, which forms the main research topic of this paper.

Pregnancy and Loneliness: The Therapeutic Value of 3D/4D Ultrasound  [PDF]
Ulrich Honemeyer, Asim Kurjak
Psychology (PSYCH) , 2014, DOI: 10.4236/psych.2014.57085
Abstract:

The fetal sensual and motoric equipment and its successful development within the maternal organism on the one hand, and the harmonic psycho-physic transformation and maturation of the woman into a mother on the other hand, are linked in dialectic inter-dependence. We describe situations in which the harmony of this process is disturbed. Visualization of the fetus in 3D and real time 3D (4D) can influence parental phantasies of the unborn, improve compromised bonding, or create bonding between fetus and (foster)-parents, and support understanding and even acceptance of fetal pathology.
