An Analysis of Preposition (Idiomatic Phrases, Prepositional Phrases and Zero Prepositions) Detection Errors in the Writing of Graduate ESL Learners of Pakistan

In this paper we describe a methodology for detecting preposition errors in the writing of ESL graduate learners. To investigate the nature of errors in the writing skill problems of graduate learners, two fifty graduate male and female learners randomly selected from four colleges and one university were asked to complete two writing skill tasks: Fifth word deletion and open composition test. The study is related to the research question: Why ESL graduate learners commit errors in their writing skills? (a) Prepositions, phrasal verbs and idiomatic phrases. It is detected that preposition overuse and preposition omission are the common problems for ESL. Besides, students deem prepositions quite tricky to use in their writing. So the findings show the wrong use of prepositions specifically ‘with, in, of’ and unnecessary insertion of prepositions. It is observed that errors are because of the interference of L1 in L2.  Besides, the final results of the two tests showed that Prepositions (prepositional verbs, prepositional phrases, phrasal verbs, zero prepositions) are quite problematic for ESL learners. The learners try to put prepositions on the same patterns of L1 which ultimately leads them towards errors.

Clinicopathological and immunohistochemical analysis of Sarcomatoid carcinoma of head and neck mucosal region: a retrospective analysis

Background: Sarcomatoid carcinoma is a biphasic tumour comprising both of malignant epithelial and mesenchymal elements derived monoclonally from same stem cells. These are unusual variants of squamous cell carcinoma and constitute less than 1% of the head and neck mucosal tumors. Only few studies have been published and needs more understanding to establish treatment guidelines. The aim of this study was to review the cases of carcinosarcoma arising from mucosal sites of head and neck and study their clinical, histological and Immunohistochemical features.Methods: Retrospective data and slides of histologically proven sarcomatoid carcinoma over a period of thirty -four months between January 2016 - October 2018 were retrieved and evaluated for various clinical and histopathological parameters.Results: Total of 22 cases were included in the study and the mean age of presentation was 58years with male: female ration 2:1. Most of the patients (81.8%) presented with a mass lesion of less than 6 months duration. The most common site was oral cavity (68.1%) followed by larynx (22.7%). Clinical stage was known in eleven cases. One case presented with pulmonary metastasis. Histopathologically, epithelial differentiation was identified in nine cases (41%) on morphology and in thirteen cases could be highlighted by cytokeratin positivity. The Mesenchymal component was arranged in sheets (63.7%) and fascicles (31.8%). Marked anaplasia and brisk mitosis wereseen in 54.5% and 19.3% respectively.  On immunohistochemistry all 22 cases were positive for Vimentin, twenty cases were positive for cytokeratin/EMA and aberrant mesenchymal markers were expressed in 10% of cases.  Follow up was available in eighteen cases out of which fourteen cases died within one year of diagnosis.Conclusions: Diagnosis of sarcomatoid carcinoma is challenging especially on small biopsy because of overlapping features with other spindle cell tumors. Understanding the clinicopathological features facilitates their diagnosis and effective clinical management

Patient-Level Cost Estimation for Health Services at Secondary Hospital, Saudi Arabia

Cost information can help to improve the quality of medical care budgeting, and it can also improve the efficient allocation of resources and patient outcomes. The objective of this study was to estimate the inpatient unit cost of healthcare services in a secondary hospital in Saudi Arabia. A cross-sectional retrospective approach was applied to categorize the inpatients discharged from the hospital from January to December 2018. A top-down costing method for cost estimation was used. We found that the overhead cost center holds 40.17% of the total hospital cost, and intermediate and final care cost centers consumed 25.50% and 34.33%, respectively. Among inpatients wards, the Surgical ward had the highest operational cost (39.27%). Human resources consumed the hospital's highest resources (75%) on salaries. The hospital's cost structure was not remarkable and needs revolutionary changes to adopt the new payment mechanism envisioned in the 2030 Saudi vision

Development and Characterization of Porous Hydroxyapatite Scaffold by Using Polymeric Sponge Method

In recent years, scrupulous attention has been given to the preparation of porous hydroxyapatite (HA). Porous HA exhibits strong bonding to the bone and provide a mechanical interlock leading to a firm fixation of the material. Bone tissue grows well into the pores, increasing strength of the HA implant. Its high surface area leads to excellent osteoconductivity and resorbability providing fast bone ingrowth. This paper briefly describes the preparation of porous HA scaffold by polymeric sponge method for artificial bone application. The technique of saturating a body of porous polyurethane foam with slurry containing HA powder, water and additives was applied and proved to be successful. The characterization of the hydroxyapatite porous scaffolds was assessed by means of scanning electron microscopy (SEM), X-ray diffraction (XRD) and Fourier transformed infrared spectroscopy (FTIR)
