Liposarcoma of the Spermatic Cord  [PDF]
Pierlesky Elion Ossibi, Hicham Anoune, Khalid El Haoudi, Karim Ibn Majdoub, Imane Toughrai, Said Ait Laalim, Khalid Mazaz
Case Reports in Clinical Medicine (CRCM) , 2014, DOI: 10.4236/crcm.2014.39113
Abstract: Few cases of Liposarcoma of the spermatic cord have been reported in the literature. This rare tumor represents 7% of malignant tumors of the spermatic cord. We report a case of an unusual liposarcoma of the spermatic cord, with respect to its sclerosing variant, occurring in a healthy looking 42 years old man. A wide local excision of the tumor was performed. Adjuvant radiotherapy may sometimes be effective on local recurrence. Even though this tumor evolves slowly, a prolonged follow up is required because of the risk of late recurrence.
Spontaneous Cholecystocutaneous Fistula of Anterior Abdominal Wall with Subcutaneous Gallstones: About a Rare Case and Review of the Literature  [PDF]
Khalid El Haoudi, Pierlesky Elion Ossibi, Salima Rezzouk, Mourad Oussaid, Karim Ibn Majdoub Hassani, Said Ait Laalim, Imane Toughrai, Khalid Mazaz
Surgical Science (SS) , 2014, DOI: 10.4236/ss.2014.52010
Abstract:

Spontaneous cholecystocutaneous fistula is a rare complication of chronic calculous cholecystitis, because currently gallstones are diagnosed and treated at an early stage. This occurrence is possible even if it seems actually to be rare. We report a case of spontaneous cholecystocutaneous fistula of Anterior Abdominal Wall with subcutaneous gallstones admitted in the medical oncology unit of HASSAN II University Hospital. An 64-year-old woman, presented with a large subcutaneous abscess in the right subcostal area with swelling. An abdominal computed tomography scan showed a subcutaneous gallstone and communication between the abscess and the gallbladder. Cholecystectomy was performed and the abdominal wall abscess was drained externally. This case report demonstrates that maintaining a high degree of suspicion of this rare entity is helpful in achieving correct preoperative diagnosis, and that computed tomography scan should be performed in all cases of unexplained abdominal wall suppuration.

6-Bromo-1,3-di-2-propynyl-1H-imidazo[4,5-b]pyridin-2(3H)-one
S. Dahmani,A. Haoudi,F. Capet,El Mokhtar Essassi
Acta Crystallographica Section E , 2010, DOI: 10.1107/s1600536810007701
Abstract: The room-temperature reaction of propargyl bromide and 6-bromo-1,3-dihydroimidazo[4,5-b]pyridin-2-one in dimethylformamide yields the title compound, C12H8BrN3O, which features nitrogen-bound propynyl substituents. The imidazopyridine fused ring is almost planar (r.m.s. deviation = 0.011 ); the propynyl chains point in opposite directions relative to the fused ring. One acetylenic H atom is hydrogen bonded to the carbonyl O atom of an inversion-related molecule, forming a dimer; adjacent dimers are linked by a second acetylene–pyridine C—H...N interaction, forming a layer motif.
6-Bromo-1-(1,2-propadienyl)-3-(2-propynyl)-1H-imidazo[4,5-b]pyridin-2(3H)-one

Acta Crystallographica Section E , 2010, DOI: 10.1107/s1600536810007695
Abstract: The reaction of propargyl bromide and 6-bromo-1,3-dihydroimidazo[4,5-b]pyridin-2-one in refluxing dimethylformamide yields the title compound, C12H8BrN3O, which features nitrogen-bound propadienyl and propynyl substituents. The imidazolopyridine fused ring is planar (r.m.s. deviation = 0.012 ); the propadienyl chain is coplanar with the fused ring as it is conjugated with it, whereas the propynyl chain is not as the nitrogen-bound C atom is a methylene linkage. The acetylenic H atom is hydrogen bonded to the carbonyl O atom of an adjacent molecule, forming a helical chain runnning along the b axis.
Bioadsorption of Pb(II) onto Anethum graveolens from Contaminated Wastewater: Equilibrium and Kinetic Studies  [PDF]
Ali Hashem, Khalid El-Khiraigy
Journal of Environmental Protection (JEP) , 2013, DOI: 10.4236/jep.2013.41012
Abstract:

In the present study we reported the feasibility of the Anethum graveolens as biosorbent to remove Pb(II) from aqueous solutions. Anethum graveolens was characterized by scanning electron microscopy and elemental analysis. The ability of Anethum graveolens to adsorb Pb(II) was investigated by using batch adsorption procedure. The effects such as pH, contact time, adsorbate concentration and biosorbent dosage on the adsorption capacity were studied. The experimental data were analysed using various adsorption kinetic models viz., the pseudo-first and second-order equations, Bangham’s equation, intraparticle diffusion and Elovich models. Results show that the pseudo-second-order equation provides the best correlation for the biosorption process. The equilibrium nature of Pb(II) adsorption at 30 has been described by the Langmuir, Freundlich, Temkin and Redlich-Peterson isotherm models. The equilibrium data fit well on Langmuir isotherm. The monolayer adsorption capacity of Pb(II) onto Anethum graveolens as obtained from Langmuir isotherm at 30 was found to be 303 mg/g. This high adsorption capacity of Anethum graveolens places this biosorbent as one of the best adsorbents for removal of Pb(II) from aqueous effluents.

Open Journal of Gastroenterology (OJGas) , 2015, DOI: 10.4236/ojgas.2015.52002
Abstract: Necrosis of the stomach is rare. It occurs when there is vascular anomalies, gastric volvulus or her-niation and in infectious gastritis. We report a case in which infectious gastritis leads to a necrotiz-ing gastritis that is treated with urgent gastrectomy.
A Cubic Spline Method for Solving a Unilateral Obstacle Problem  [PDF]
El Bekkey Mermri, Abdelhafid Serghini, Abdelmajid El hajaji, Khalid Hilal
American Journal of Computational Mathematics (AJCM) , 2012, DOI: 10.4236/ajcm.2012.23028
Abstract: This paper, we develop a numerical method for solving a unilateral obstacle problem by using the cubic spline collocation method and the generalized Newton method. This method converges quadratically if a relation-ship between the penalty parameter and the discretization parameter h is satisfied. An error estimate between the penalty solution and the discret penalty solution is provided. To validate the theoretical results, some numerical tests on one dimensional obstacle problem are presented.

Abstract: PURPOSE: Leiomyosarcoma of the breast is extremely rare. To date, the factors that are predictive of patient prognosis have not been identified. To clarify the nature of leiomyosarcoma of the breast, and also to establish the proper treatment strategy, we report this case We report this case while discussing The Clinical presentation, diagnosis, therapy and pathologic feature. INTRODUCION: Sarcomas comprise less than 1% of all primary breast neoplasms and only a minority of these are leiomyosarcomas. There were only 35 cases being reported in English literature. The mainstay of treatment is surgical excision with clear margins and longterm followup is essential. Its prognosis is better compared to other breast sarcoma. CASE PRESENTATION: We report a case of primary leiomyosarcoma of the breast occurring in young female patient which was successfully treated by surgery and radiotherapy. CONCLUSION: According to literature data, primary leiomyosarcoma is characterized by a better prognosis compared with other breast sarcomas, To date, the factors that are predictive of patient prognosis have not been identified. .The rarity and diagnostic difficulty imposed a multidisciplinary approach.

Khalid Mazine, Hamdaoui Mohammed, El Ghazi Karima, Ousadden Abdelmalek, Mazaz Khalid, Ibrahimi Adil, Ait Taleb Khalid, Benajeh Dafrallah, Benjelloun Elbachir
Open Journal of Gastroenterology (OJGas) , 2017, DOI: 10.4236/ojgas.2017.75017
Abstract: Background: Metal stents for unresectable pancreatic cancer are associated with longer patency and superior cost-effectiveness. However, they are too expensive to be recommended routinely in developing countries. Moreover, a debate on outcome results in these patients who receive plastic biliary endoprothesis versus surgical bypass as palliation of obstructive jaundice. We aimed to compare retrospectively the outcomes in patients treated with plastic stent or surgical bypass as a palliative option for these patients. Patients and Methods: We have examined data for patients (n = 86) who received endoscopic stenting (n = 64) or surgical bypass (n = 22), from January 2013 to November 2016, as a palliative treatment for obstructive jaundice from inoperable cancer head pancreas. Results: Serum bilirubin and CA19.9 levels were comparable in age and gender matched patient groups. Moreover, post-operative major complications and 30-days mortality showed no significant differences among patient groups. However, surgical bypass treated patients showed longer initial hospital stay (9 vs. 6 days, p = 0.014), higher cost ($1600 vs. $1088) and longer survival (192 vs. 101 days, p = 0.003) compared to endoscopy-stenting treated patients. Re-hospitalization was required for 5 stented patients (averaged $448). Conclusion: Biliary bypass surgery for unresectable pancreatic cancer may improve patient survival, although prolongs hospital stay. It may be recommended for relatively fit patients with a life expectancy of 6 months and more.
Productivity Improvement Model without Increasing Operation’s Risk and Fatigue  [PDF]
Adel Al-Shayea, Abdulaziz El-Tamimi, Khalid Al-Saleh, Khalid Al-Yami
Engineering (ENG) , 2011, DOI: 10.4236/eng.2011.311140
Abstract: Productivity improvement of an operation without increasing operation risk and operation fatigue that increase the needed relaxation allowance is an important subject in process design. This research subject stimulates researchers to focus on improving the productivity of the whole production process by changing the technique of performing significant operations in the process. However, two important issues that affect the implementation of any new technique were not considered in the pervious research works. These are the risk magnitude of the new technique on the workplace environment and the fatigue level that affect human's health. In this paper, a model was developed that maximize the productivity of the production process by selecting the best technique to perform significant process operations among proper candidate techniques that improve these operations productivity while minimizing these operations risk and fatigue.
