Background: Human face is highly vascular region and vascularity to the skin and other organs is an important indicator of health and disease. Change in blood flow is affected by aging, diabetes, high blood triglycerides, cigarette smoking etc. With so many factors that can alter blood flow in the skin, normal blood flow is important to know for comparison to diseased state. Blood flow in superficial arteries of face has not yet been described, therefore this study was designed to establish baseline blood flow values in arteries of face. Materials and Methods: Blood flow of right and left side was assessed at level of facial and infraorbital artery. Categorical variables were presented in form of frequency and percentages was done by using Mann-Whitney U. Wilcoxon Signed Ranks test was used to compare left and right facial and infra orbital arteries. Results: Peak systolic velocity of right and left facial artery had a significant difference having right side mean of 67.02±12.48 and left side mean as 72.67±11.69. Facial artery diameter of right and left side also had significant difference with mean of 0.14±0.02 and 0.15±0.02 respectively. Conclusion: No difference was found between vascularity in male & female and left or right side. The study might be useful to establish normal baseline values of various parameters on both sides of face in male and female adults. This study may become important reference for future studies measuring blood flow and even progression of vascular diseases may be assessed by indexes developed on the basis of these studies.
Mesenchymal chondrosarcoma is a rare aggressive neoplasm affecting the bones of young adults. It also arises extraskeletal in CNS, soft tissue and other organs. Intracranial and those that originate from the dura mater are very rare. These tumors constitute an entirely different entity from classical chondrosarcoma. These are characterized by a bimorphic histological pattern composed of highly undifferentiated small round to oval cells and islands of well-differentiated hyaline cartilage with calcification and ossification. We hereby report a case of mesenchymal chondrosarcoma arising from the right tentorium cerebelli in a 40-year-old man with symptoms of mass effect. Histological examination demonstrated sheets of round to oval cells with islands of hyaline cartilage. The diagnosis of mesenchymal chondrosarcoma was made after a thorough microscopic assessment. Tumor in addition to cellular component also revealed a prominent cartilaginous component. We hereby discuss the morphological features of mesenchymal chondrosarcoma arising in the CNS, the differential diagnoses of small round-cell tumors within the CNS, and the differentiating features of mesenchymal chondrosarcoma from the other differential diagnoses.
Objective: To observe and compare relationship of High Resolution Computed Tomography severity score with presenting symptoms of COVID-19 positive patients in mild, moderate and severe disease and to analyze the trends of morbidity and mortality in Pakistan. Study Design: Retrospective Observational study Subjects and Methods: All OPD and admitted adult male and female patients serially presented to Fatima Memorial and Sir Ganga Ram Hospital Lahore with positive COVID PCR test or clinical symptoms were included in the study. These patients were classified in three groups; Group I: Mild disease, i.e. symptomatic patients who didn’t need hospital admission or oxygen support. Group II: Moderate disease, i.e. patients having oxygen saturation more than 90% & needing oxygen support at times, and Group III: severe disease, i.e. patients needing hospital admission or ventilator support and having oxygen saturation less than 90%. High resolution chest CT scan was the approach in all cases. CT severity score was used to assess the severity of lung parenchymal involvement by COVID-19 on all the HRCT. Data collected was entered and analysis made using SPSS v 25. Results: Total number of patients were 200(100%) with age ranging from 14-85 years and mean age was 49.5+ 5 years, out of which 135(67%) were males and 65(32%) were females with male to female ratio 2:1. HRCT scans of all patients were done with COVID PCR test positive in 146(73%) patients. Group I had 98(49%) patients, 87(43.5%) patients were included in Group II and 15(7.5%) patients in Group III. Oxygen was required in 78(39%) patients from group II and 14(7%) patients from severe disease required ventilator. Conclusion: Our research work presented the trends of CT severity scoring having positive correlation to clinical symptoms of patients. Moreover, most of the patients in our country were having mild and moderate disease and only 7% patients showed severe disease symptoms and CT scoring in our study. Out of those severe disease patients, mortality was only 1% as compared to 2.89% mortality reported in Iran. Keywords: COVID-19 infection, HRCT Chest, Severity score
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
