Abstract Introduction Refinements in the modern computed tomography (CT) imaging techniques have led to anatomical variations in the fissures of lung being diagnosed more frequently. So far, majority of the studies conducted are cadaveric. There is paucity of studies in this aspect based on chest CT images. Hence, we undertook this study to find the anatomical variations in the fissures. Prior detection of anatomical abnormalities is important to reduce postoperative complications in lung resection surgeries. Materials and Methods This was a cross-sectional study conducted over a period of 2 years. Data were collected from the patients who underwent CT scan thorax. Patients in whom normal anatomy of lung was distorted and cases where both lungs were not visualized completely were excluded from the study. All the CT images were reviewed by a single radiologist. The presence or absence of the normal and accessory pulmonary fissures, as well as the continuity of each fissure, was recorded by the radiologist. Data were compiled and analyzed. Results The study population consisted of 394 (70.4%) males and 166 (29.6%) females, totaling 560 cases. Fissural variations were detected in 22.9% (n = 128). Also, 17.5% (n = 98) fissural variations were seen in males and 5.4% (n = 30) fissural variations were seen in females. Further, 54.7% (n = 70) of variations were detected in the right lung and 45.3% (n = 58) in the left lung. The most common fissural variation noted was right incomplete oblique fissure with a frequency of 8.4% cases (n = 47). The most common accessory fissure detected was inferior accessory fissure. Total 22 cases were detected in both the lungs, 17 cases in male and 5 in female. Conclusion Anatomical variations in fissures were found to be more in the right lung than the left lung. Accessory fissures were detected in higher incidence on the right side.

Abstract Background Medico-legal or forensic autopsy is a special type of autopsy performed under the orders of a legal authority in circumstances involving unnatural, suspicious or criminal deaths. Gross and histopathological studies of viscera in medico-legal autopsies have been observed to serve as crucial tool in the detection of undiagnosed disease conditions and the resulting findings may closely represent the general population. Methods A prospective cross sectional study was carried out at the Muhimbili National Hospital (MNH) department of pathology, to medico-legal autopsies received at the MNH mortuary. The study included 103 cases in an eight month period. Both lungs were weighed for each case and tissue samples were collected from each lobe, in both lungs. Other gross findings were observed and recorded. Tissue sections were made and stained with hematoxylin and eosin and evaluated under a microscope. Results Out of 103 cases studied, 88.3% were male with mean age of 35.8 + 16.6 years. In females, the mean age was 31.6 + 10.4 years. The mean weight of lungs was found to be 627.3 + 138.5g and 591.7 + 129.7g for the right and left lung, respectively, in males. In females, the mean weight of lungs was 616.7 + 166.1g and 583.3 + 155.8g for the right and left lung, respectively. More than half (53.4%) of lung samples had some pathological disease, and the leading diagnosis was pulmonary congestion/oedema (22.3%) followed by lobar pneumonia (18.5%). Age was found to relate with the observed histological diagnosis of the lungs. Conclusion Males, especially the youth and adults are the main victims of medico-legal deaths. The study also revealed high prevalence of undiagnosed lung diseases in victims of medico-legal deaths. These findings may reflect heavy burden of lung diseases in the general population.

Introduction: The knowledge of anatomical variations of the coronary ostia is an important factor in the study of Coronary Heart Disease (CHD). With the adaptation of sedentary life style and increasing stress, CHD has become the major cause of death in many countries. Aim: To describe the location, size and shape of the coronary ostia in cadaveric hearts. Materials and Methods: Descriptive cross-sectional study was carried out in 110 adult human hearts, 90 males and 20 females with a mean age of 66 years, which were collected from the mortuary from March 2017 to March 2019. The aorta was dissected and the aortic sinuses were opened, the number, location, size, shape and anomalous presence of accessory coronary ostia was noted and the measurements were taken using vernier calipers. Results: The Right Coronary Artery (RCA) was seen taking origin from the anterior aortic sinus and the Left Coronary Artery (LCA) from the left posterior aortic sinus in all the 110 hearts. The mean diameter of the Left Coronary Ostia (LCO) was 3.66±0.40 mm and found to be greater than the Right Coronary Ostia (RCO) 3.43±0.38 mm. Variations in the location and shape of the RCO and LCO were noted, and presence of single accessory coronary ostia was observed in five cases. Presence of multiple accessory coronary ostia was observed in only one case and its presence was found to be very rare. Conclusion: The diameter of the LCO was found to be greater than the RCO and the shape was circular in most of the coronary ostia. The majority of the coronary ostia were found to be located within the aortic sinuses below the Sinutubular Junction (STJ). Anatomical knowledge of the coronary ostia in the ascending aorta is very important during cardiac interventions around the aortic root.

Abstract The left lung usually has an oblique fissure that divides it into superior and inferior lobes. Some variants in the lobar fissure are well known, but the knowledge of certain uncommon variants will enhance our anatomical understanding and proper identification of the bronchopulmonary segments. Several imaging techniques have been used to describe anatomical variations of the lung, but studies that utilize dissections as tools for understanding lobar variations were limited. In this report, we described an incomplete horizontal fissure, bifurcated accessory fissure, incomplete superior and middle lobes, and fibrous condensation of the left lung pulmonary pleura observed during dissection. The knowledge of these anatomical variations will be useful in surgical segmental resection and lobectomy, and for accurate interpretations of medical diagnostic images.

Background: CT imaging of nose and paranasal sinuses is to confirm the diagnosis, localize the disease, characterize the extent of pathology and describe any anatomical variations. A careful histopathological examination (HPE) is nesessary to decide the nature of a specific lesion. Objective: To observe performance of CT scan as a sensitive modality in the diagnosis of sinonasal mass by comparing with the findings of histopathological examination. Methods: This cross sectional study in Dhaka Medical College Hospital (DMCH). From 01/ 07/2013 to 30/06/2014 (One year), 42 patients were selected. Resuls: Here male and female ratio was found 1.4:1 So, the incidence of sinonasal growth slightly higher in male (59.3%) compared to the female (40.6%).Incidence of malignant tumour was found more in age group above 60 years. Out of 32 patients, 6 patients (18.7%) were diagnosed histopathologically as infective, 7 patients (21.8%) were benign and 19 patients (59%) had malignant sinonasal mass.

We report an unusual case of a 35-year-old Ivorian migrant with an abdominal mass and medical history relevant for human immunodeficiency virus-2 positivity with a CD4/CD8 ratio of 0.63; Mantoux and lymphocyte stimulation tests (QuantiFERON) were positive. 3D-CT images revealed a voluminous non-homogeneous retroperitoneal mass in the right abdominal region presenting no significant contrast impregnation. Thoraco-abdominal aorta presented diffuse-altered morphology with multiple ectasias throughout its course and an aneurysm at the level of the subrenal tract. The patient underwent vascular surgery. Mycobacterium tuberculosis complex was detected by polymerase chain reaction performed on intraoperative tissue specimens. Postoperative course was uneventful. After surgery, 3D-CT images showed no signs of malfunction of the prosthesis. At last, at 6-month follow-up, the patient was well. Cross-sectional imaging techniques, such as contrasted-CT, are essential and allow for making diagnosis, assessing disease activity, and evaluating post-treatment condition. 3D reconstruction permits an appropriate patient care by means of an excellent visualization and staging of the disease process.

Background: Intrathoracic Lymphadenopathy (ITLN) in Human Immunodeficiency Virus (HIV) infected patients may have various etiologies and prognoses. Etiologies of ITLN can be distinguished based on the distribution of enlarged lymph nodes. Sometimes tuberculosis (TB) is the first sign of underlying HIV infection. Objective: We sought to determine ITLN distribution and associated pulmonary findings in TB/HIV co-infection using Computed Tomography (CT) scan. Methods: In this retrospective, observational, cross-sectional study, chest CT scans of 52 patients with TB/HIV co-infection were assessed for enlarged intrathoracic lymph nodes (>10 mm in short axis diameter), lymphadenopathy (LAP) distribution, calcification, conglomeration, the presence of hypodense center and associated pulmonary abnormalities. LAP distribution was compared in TB/HIV co-infection with isolated TB infection. Results: Mediastinal and/or hilar LAP were seen in 53.8% of TB/HIV co-infection patients. In all cases, LAP was multinational. The most frequent stations were right lower paratracheal and subcarinal stations. Lymph node conglomeration, hypodense center and calcification were noted in 25%, 21.4% and 3.5% of patients, respectively. LAP distribution was the same as that in patients with isolated TB infection except for the right hilar, right upper paratracheal and prevascular stations. All patients with mediastinal and/or hilar adenopathy had associated pulmonary abnormalities. Conclusion: All patients with TB/HIV co-infection and mediastinal and/or hilar adenopathy had associated pulmonary abnormalities. Superior mediastinal lymph nodes were less commonly affected in TB/HIV co-infection than isolated TB.

Abstract Background Coronavirus disease 2019 (COVID-19) has caused a global pandemic that has raised worldwide concern. This study aims to investigate the correlation between the extent of lung infection and relevant clinical laboratory testing indicators in COVID-19 and to analyse its underlying mechanism. Methods Chest high-resolution computer tomography (CT) images and laboratory examination data of 31 patients with COVID-19 were extracted, and the lesion areas in CT images were quantitatively segmented and calculated using a deep learning (DL) system. A cross-sectional study method was carried out to explore the differences among the proportions of lung lobe infection and to correlate the percentage of infection (POI) of the whole lung in all patients with clinical laboratory examination values. Results No significant difference in the proportion of infection was noted among various lung lobes (P > 0.05). The POI of total lung was negatively correlated with the peripheral blood lymphocyte percentage (L%) (r = − 0.633, P < 0.001) and lymphocyte (LY) count (r = − 0.555, P = 0.001) but positively correlated with the neutrophil percentage (N%) (r = 0.565, P = 0.001). Otherwise, the POI was not significantly correlated with the peripheral blood white blood cell (WBC) count, monocyte percentage (M%) or haemoglobin (HGB) content. In some patients, as the infection progressed, the L% and LY count decreased progressively accompanied by a continuous increase in the N%. Conclusions Lung lesions in COVID-19 patients are significantly correlated with the peripheral blood lymphocyte and neutrophil levels, both of which could serve as prognostic indicators that provide warning implications, and contribute to clinical interventions in patients.

Abstract Background: Exceptional children, like other children, have the right to be educated in a safe environment. Disasters are considered as serious issues regarding safety and security of educational environments. Following disasters, vulnerable groups, especially children with handicaps and disabilities are more likely to be seriously injured. Thus, the present study aimed to evaluate the safety and disaster risk assessment of exceptional schools in Tehran, Iran. Method: The cross-sectional study was conducted in exceptional schools in Tehran, 2018. First, 55 exceptional schools in all grades were selected based on census sampling method and evaluated by using a checklist designed by Tehran Disaster Mitigation and Management Organization (TDMMO) and Ministry of Education in 2015. The data were analyzed using Excel software and statistical descriptive tests. Result: Based on the results, school facilities are worn and have unsafe elevators (least safety: 7.69%), yards (least safety: 9.52%), laboratories (least safety: 16.67%), libraries (least safety: 24.24%), fire extinguishing systems (least safety: 28.99%), and storage rooms and kitchens (least safety: 33.33%) which require immediate considerations. In total, the safety of exceptional schools in this study was 70.13%, which suggests medium-risk level. Conclusion: The educational settings must be reconsidered, along with identifying the risk and safety at school. In addition, a standard should be established for evaluating safety, especially in exceptional schools.

ObjectivesTo provide an overview of the demographic characteristics of patients with positive blood alcohol concentration (BAC) and to investigate the performance of brain CT scans in these patients.DesignCross-sectional study.SettingTaiwan.Participants2192 patients who had undergone a test for blood alcohol of 13 233 patients registered in the Trauma Registry System between 1 January 2009 and 31 December 2012. A BAC level of 50 mg/dL was defined as the cut-off value. Detailed information was retrieved from the patients with positive BAC (n=793) and was compared with information from those with a negative BAC (n=1399).Main outcome measuresGlasgow Coma Scale (GCS) and Injury Severity Score (ISS) as well as the performance and findings of obtained brain CT scans.ResultsPatients with positive BAC had a higher rate of face injury, but a lower GCS score, a lower rate of head and neck injury, a lower ISS and New Injury Severity Score. Alcohol use was associated with a shorter length of hospital stay (8.6 vs 11.4 days, p=0.000) in patients with an ISS of <16. Of 496 patients with positive BAC who underwent brain CT, 164 (33.1%) showed positive findings on CT scan. In contrast, of 891 patients with negative BAC who underwent brain CT, 389 (43.7%) had positive findings on CT scan. The lower percentage of positive CT scan findings in patients with positive BAC was particularly evident in patients with an ISS <16 (18.0% vs 28.8%, p=0.001).ConclusionsPatients who consumed alcohol tended to have a low GCS score and injuries that were less severe. However, given the significantly low percentage of positive findings, brain CT might be overused in these patients with less severe injuries.
