Objective: The aim of this study was to establish cervical cancer patients’ expectations and experiences during high dose-rate (HDR) intracavitary brachytherapy procedure, as part of a process to develop guidelines for quality patient-centered care. Methodology: A prospective, qualitative study with a descriptive phenomenological approach was used. Purposive sampling was carried out to recruit 31 women undergoing HDR brachytherapy for cervical cancer from June to August 2020 at the National Institute of Oncology in Rabat. Semi-structured, one-to-one interviews guided by a theme list were conducted by a female radiation oncologist in Arabic before, during and after treatment. The following aspects were discussed: expectations, experiences in the waiting room, in the treatment room, and suggestions for improvement. Data was transcribed, translated and thematic analysis performed. Results: Most of the patients felt unprepared and did not have a clear understanding of brachytherapy. Brachytherapy was a difficult experience causing fear and anxiety throughout treatment. Most women dreaded the procedure, before receiving the first treatment and even after having had one. Pain was a major problem for the participants. Some women compared this pain to childbirth, a process they preferred to brachytherapy. Patients agreed that the preventative medication received was not efficient to relieve the pain. Despite these negative experiences, patients were left with a positive outlook. Dialogue with the healthcare professionals, support from their family and fellow patients, envisaged outcomes and desires to heal were used to cope, whilst faith and spirituality gave them strength to endure the procedure. Conclusion: Women undergoing uterovaginal brachytherapy for cervical cancer experience pain and emotional distress. Providing patients with adequate information, more sensitive support during the procedure and debriefing afterwards could lessen feelings of fear and anxiety. Our fi

Sarcomatoid Carcinoma of the Mandible: A Case Report and Literature Review

引用

Journal of Cancer Therapy 2022年第6期13卷 323-330页

作者： Kenza Benali Tayeb Kebdani khalid Hassouni Sanaa el Majjaoui Hanan el Kacemi Noureddine Benjaafar Department of Radiation Oncology National Institute of Oncology Rabat Morocco Faculty of Medicine Mohammed V University Rabat Morocco

Background: Sarcomatoid carcinoma is a rare biphasic malignancy with an epithelial and mesenchymal component. Given its histological particularity, the diagnosis of this tumor still represents a challenge for pathologists and surgeons. Sarcomatoid carcinoma of the mandible is a very rare and aggressive entity. To date, only sporadic cases have been reported in the literature. Aim: To report a rare case of aggressive mandibular sarcomatoid carcinoma treated with radical surgery and adjuvant chemoradiation, and discuss the related literature. Case Report: We introduce a rare case of mandibular sarcomatoid carcinoma occurring in a 34-year-old woman. Treatment consisted of radical surgery and re-excision for positive margins, adjuvant radiation therapy (66 Gy in 33 fractions in simultaneous integrated boost delivered using Volumetric Modulated Arc Therapy) and Cisplatin-based concurrent chemotherapy. The tumor displayed aggressive behavior and high metastatic potential, causing tumour recurrence and extensive lung metastasis. Conclusion: Sarcomatoid carcinoma of the mandible is an extremely rare malignant entity, with a high tendency for local recurrence, distant metastasis. Treatment involves radical surgery and adjuvant chemoradiation, although the outcome and prognosis might be poor.

Modeling of nonlinear envelope solitons in strongly coupled dusty plasmas:Instability and collision

引用

Chinese Physics B 2015年第3期24卷 237-247页

Modeling of instability and collision of nonlinear dust-acoustic（NDA） envelope solitons in strongly coupled dusty plasmas（SCDPs） is theoretically investigated. The SCDPs consists of strongly correlated negatively variable-charged dust grains and weakly correlated Boltzmann electrons and ions. Using the derivative expansion perturbation technique, a nonlinear Schr dinger-type（NLST） equation for describing the propagation of NDA envelope solitons is derived. Moreover,the extended Poincar′e–Lighthill–Kuo（EPLK） method is employed to deduce the analytical phase shifts and the trajectories after the collision of NDA envelope solitons. In detail, the results show that both modulation instability and phase shift after collision of NDA envelope solitons will modify with the increase in the effects of the viscosity, the relaxation time, and the dust charge fluctuation. Crucially, the modeling of dust-acoustic envelope solitons collision, as reported here, is helpful for understanding the propagation of NDA envelope solitons in strongly coupled dusty plasmas.

Surgical Bypass versus Endoscopic Stenting for Unresectable Head Pancreatic Cancer, Which Palliative Treatment Is Better in Developing Countries, Morocco as an Example

引用

Open Journal of Gastroenterology 2017年第5期7卷 154-164页

作者： khalid Mazine Hamdaoui Mohammed el Ghazi Karima Ousadden Abdelmalek Mazaz khalid Ibrahimi Adil Ait Taleb khalid Benajeh Dafrallah Benjelloun elbachir Department of Visceral Surgery Faculty of Medicine and Pharmacy of Fez University Hospital Hassan II—Fes Sidi Mohamed Ben Abdellah University Fez Morocco

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.

Integration of Point and Remote Sensing Data for Monitoring Surface Runoff around Madinah City, Saudi Arabia

引用

Advances in Remote Sensing 2015年第4期4卷 287-302页

作者： elSayed Ali Hermas Ibrahim Mohammed el-Barodi khalid Al-Ghamdi The National Authority of Remote Sensing and Space Sciences Cairo Egypt Geography Department Faculty of Social Sciences Umm Al-Qura University Makkah Saudi Arabia

In response to sporadic rainy storms, the fluvial catchments in the northern, eastern and southern regimes of Medina City produce surface runoff that varies in the frequency and magnitude. The determination of the most frequently flowing catchment(s) through each precipitation event and the spatial characteristics of surface runoff still represent gaps in understanding the hydrological processes associated with flash floods in arid environments. The lack of data in particular precipitation records at reliable temporal and spatial scales is considered one of the essential constraints in understanding these issues. The integration of point precipitation records and the multi-temporal satellite imagery such as LandSat TM and the Tropical Rainfall Monitoring Mission (TRMM) helped retrieve significant surface runoff events through two decades of the last century around Madinah City. The spectral signatures of surface runoff have been clearly identified from the optical remote sensing images acquired after each precipitation event. Investigating the spectral signatures of surface runoff along with its corresponding precipitation records from both Madinah climatic station and the TRMM monthly precipitation indicated that 1) there is no specific threshold of the amount of precipitation required for developing surface runoff;2) while Madinah climatic station provided records of precipitation on the majority of surface runoff, it did not provide records on some monitored surface runoff events;3) the spatial distribution and magnitude of the monthly precipitation of the TRMM images of 1998 have been conformed with all surface runoff events developed in W. Al-Aqeeq;and 4) W. Al-Aqeeq is considered the most frequently flowing valley around Madinah City because it developed surface runoff in response to all the precipitation events. These results emphasize the necessity of establishing a number of climatic and gauge stations in selective locations within the drainage basins aroun
