Cavernous Gastric Hemangioma as an Unusual Cause of Upper Gastrointestinal Bleeding in a Young Woman

Gastric hemangiomas (GHs) are extremely rare vascular lesions of mesodermal origin that may occur in isolation or in conjunction with underlying congenital pathology. Due to the scarcity of these tumors, there is no standardized diagnostic method; however, many have found the combination of endoscopic investigation and radiographic imaging to be most effective, with the presence of phleboliths on computerized tomography as being pathognomonic for GHs. Surgical treatment for symptomatic lesions is curative with no reports of recurrence. We describe a 21-year-old woman who presented with epigastric pain and one episode of 250 mL hematemesis earlier that morning. Under the impression of an upper gastrointestinal bleed due to peptic ulcer disease, esophagogastroduodenoscopy was performed which revealed a 5-cm blood clot-like mass similar in appearance to that of a II-b peptic ulcer, but the presence of a bridging fold led to the suspicion of a possible submucosal tumor. Dynamic computerized tomography scan showed similar findings, and the patient was referred for surgical intervention. Laparoscopic distal gastrectomy was performed with the final diagnosis of cavernous GH made via histological evaluation. The patient was discharged 9 days later with no complications. This case puts emphasis on the importance of considering cavernous GH as a potential cause of severe upper GI bleeding especially in those with atypical demographic profile and history.

Anterior Skull Base Analysis from Coronal and Reconstructed Computed Tomography: Radio-Anatomical Study

Endoscopic sinus and skull base Surgery has gained significant improvement widely all over the world. A computerized tomography (CT) scan provides a detailed anatomy of the skull base especially the bone framework. This study aims to analyze the fixed anatomical bony landmarks of the anterior skull base through coronal and reconstructed CT in the context of the Nepalese population and guide the surgeon to perform endoscopic sinus and skull base surgery safely. This Prospective study includes 70 Computerized Tomography scans of Paranasal sinuses. The different measurement from nasal floor to skull base was taken in coronal and reformatted sagittal CT scan. Mean, standard deviation, minimum and maximum values were analyzed using descriptive statistics. Student T-test was applied to compare between right and left side. This study includes 75 patients between 18 to 77 years. The measurement from nasal floor to the cribriform plate and ethmoidal roof in right and left side were, mean± SD (47± 4.1, 45.3±4.3, 47.9±5.1, and 49±8.5 mm) respectively. Mean Take off angle at the cribriform plate was 43.9 ±10.9°on right side and 43 ± 9.4° on the left side. The distance from the nasal spine to the skull base (mean ± SD) at nasofrontal recess, bulla ethmoidalis, and the junction of sphenoethmoid levels at right sides were 51.5 ± 4.7, 52.9 ± 4.1, and 61.2 ±4.7 little higher at left side. This study provides a detailed analysis of the anterior skull base in coronal and sagittal CT scans which helps to reduces complications.

FREQUENCY OF BONE EROSION ON COMPUTERIZED TOMOGRAPGHY SCAN IN ALLERGIC FUNGAL RHINOSINUSITIS

Objective: To analyze the frequency and sites of bone erosion on computerized tomograghy scan in Allergic Fungal Rhinosinustis in Pakistan. Study Design: Retrospective observational study. Place and Duration of Study: Department of ENT, Combined Military Hospital Lahore, Malir Karachi and Rawalpindi, from Jan 2010 to Dec 2019. Methodology: Total 230 cases of Allergic Fungal Rhinosinusitis were screened, out of which 85 patients having bone erosions on computerized tomograpghy scan were included in the study. Bone erosion in different paranasal sinuses and their sub sites were evaluated. Depending upon the number of bone erosion, patients were divided into three categories as mild, moderate and severe. Those having erosion at a single site were labelled as mild, those with two sub sites of erosion as moderate and those with more than two subsites of erosion were labelled as severe cases. Results: Detailed evaluation of computerized tomography scan of paranasal sinuses revealed bone erosion in 85/230 (36.9%) cases. Mean affected age was 23.96 ± 12.71 years. There were 52 (61.1%) males and 33 (38.9%) females. Ethmoid sinus was the most commonly involved sinus to have bone erosions 55 (38.19%) followed by maxillary sinus 38 (26.38%) then sphenoid sinus 27 (18.75%) and lastly frontal sinus 24 (16.6%). Out of 85 patients 48 (56.1%) were having mild, 22 (25.8%) moderate and 15 (17.6%) had severe disease. Conclusion: Allergic Fungal Rhinosinusitis has high frequency of bone erosion. Computerized tomography scan is an important and effective investigation in finding these bony erosions and ethmoid sinus is the.....

The use of modern minimally invasive technologies and imaging (CT) methods in the diagnosis and surgical treatment of endometrial hyperplastic processes and combined gynecological pathology

On the basis of retrospective and prospective analysis of case reports of 540 patients with recurrent endometrial hyperplasia and combined intrauterine pathology (recurrent endometrial hyperplasia + hysteromyoma and/or adenomyosis) some aspects of surgical treatment of the pathology are considered, the effectiveness of different kinds of endoscopic operations is analyzed. Potentialities of spiral computerized tomography (SCT) for diagnosis of uterine disease are examined.

Analysis of Drosophila cardiac hypertrophy by micro-computerized tomography for genetic dissection of heart growth mechanisms

Heart failure is often preceded by pathological cardiac hypertrophy, a thickening of the heart musculature driven by complex gene regulatory and signaling processes. The Drosophila heart has great potential as a genetic model for deciphering the underlying mechanisms of cardiac hypertrophy. However, current methods for evaluating hypertrophy of the Drosophila heart are laborious and difficult to carry out reproducibly. Here we demonstrate that micro-computerized tomography (microCT) is an accessible, highly reproducible method for non-destructive, quantitative analysis of Drosophila heart morphology and size. To validate our microCT approach for analyzing Drosophila cardiac hypertrophy, we show that expression of constitutively active Ras (Ras85DV12), previously shown to cause hypertrophy of the fly heart, results in significant thickening of both adult and larval heart walls when measured from microCT images. We then show using microCT analysis that genetic upregulation of store-operated Ca2+ entry (SOCE) driven by expression of constitutively active Stim (StimCA) or Orai (OraiCA) proteins also results in significant hypertrophy of the Drosophila heart, through a process that specifically depends on Orai Ca2+ influx channels. Intravital imaging of heart contractility revealed significantly reduced end diastolic and systolic dimensions in StimCA and OraiCA expressing hearts, consistent with the hypertrophic phenotype. These results demonstrate that increased SOCE activity is an important driver of hypertrophic cardiomyocyte growth, and demonstrate how microCT analysis combined with tractable genetic tools in Drosophila can be used to delineate molecular signaling processes that underlie cardiac hypertrophy and heart failure.
