Abstract:
Background Intra-abdominal hypertension and abdominal compartment syndrome are significant sources of morbidity and mortality in the post-surgical and trauma patient. Several anatomic variables may contribute to the inability to close the abdomen such as retraction of the abdominal wall and intra-abdominal volume changes. This study seeks to quantify these changes and determined which predominates. Methods Retrospective analysis of computed tomography scans of patients whose abdomens could not be closed secondary to intra-abdominal hypertension. Patients were included who had computed tomography scans available with both an open abdomen and after primary abdominal wall closure. Abdominal wall lengths along with total abdominal, intra-peritoneal, and retroperitoneal cross-sectional areas were measured at two anatomic levels. Results Seven patients’ computed tomography scans were evaluated. The closed abdominal wall lengths averaged 2.3 cm and 2.1 cm longer after closure at each point of measurement (p = 0.002 and p = 0.03). Total abdominal cross-sectional area decreased post-closure by 14% for both measurements (p = 0.009 and p = 0.04). Conclusion Measurable increases in intra-abdominal cross-sectional area and decreases in abdominal wall length both contribute to the inability to safely close the abdomen in patients with intra-abdominal hypertension. These findings support the use of multimodal techniques in the management of the open abdomen.

Abstract:
Background: Acute abdominal pain is a common chief complaint in patients examined reporting to emergency department. The sensitivity of CT is 96% in acute abdomen. In order to decrease the mortality and morbidity rate, an efficient and correct diagnosis should be given for these patients. When investigations, like USG examinations are inconclusive, in such cases, multi-detector computer tomography is a widely accepted primary investigation of choice in patients coming with intense abdominal pain. The aim of the study was to evaluate the accuracy of MDCT in diagnosis of acute abdomen; document the sensitivity and specificity of MDCT; the incidence of different pathologies presenting as acute abdomen.Methods: Prospective study on 64 subjects with acute pain abdomen was subjected to MDCT in GMC Srinagar. The duration of this study was from January to May 2019.Results: About 36 patients were females and 28 were males. Youngest patient had an age of 7 years to eldest patient having age of 79 years. Most common causes of acute abdomen were acute pancreatitis in 21.8, acute appendicitis in 15.6% and bowel obstruction in12.5%. In our study the sensitivity, specificity and positive and negative predictable values of MDCT were 95.0%, 75%%, 98.3% and 60% respectively.Conclusions: We conclude that MDCT has high sensitivity and accuracy rate. In inconclusive cases, MDCT is recommended to arrive at a definitive diagnosis. The results obtained in the study were comparable to pioneer studies conducted worldwide.

Abstract:
Abstract Background Omental infarction is a rare cause of acute pain abdomen and is difficult to diagnose clinically due to nonspecific clinical features. Multidetector computed tomography (MDCT) imaging of the abdomen is essential for the diagnosis of omental infarction and is also crucial to rule out appendicitis and other causes of acute pain abdomen. Objective The main purpose of this article is to describe the MDCT features of omental infarction in clinching the diagnosis and differentiating it from its clinical mimics. Methods CT findings of five patients with diagnosed omental infarction were retrospectively reviewed from 2014 to 2019. All patients presented with pain abdomen on the right side of the abdomen with various clinical diagnoses. MDCT was done for diagnosis and features evaluated include size of the lesion, location, relation to colon, and findings that were correlated to clinical presentation and etiology. Results Age distribution ranged between 36 and 55 years with female predominance. Out of five cases, one was secondary omental infarction due to inguinal hernia causing omental torsion and the other four cases were of unknown etiology. Three cases were managed conservatively and the other two cases were surgically managed. Three lesions were in right iliac fossa and two lesions were in the supraumbilical region on the right side. Conclusion Omental infarction should be considered important in the differential diagnosis of acute pain abdomen mimicking acute appendicitis and requires CT abdomen to establish diagnosis. Knowledge of typical imaging findings and application for diagnosis are important, as it is a self-limiting disease and can avoid unnecessary surgical interventions.

Abstract:
Radiography is a common radiologic investigation despite abundant evidence of its limited diagnostic value. On the other hand, computed tomography (CT) has a high diagnostic value and is widely considered to be among the most important advances in medicine. However, CT exposes patients to a higher radiation dose and it might therefore not be acceptable simply to replace radiography with CT, despite the powerful diagnostic value of this technique. At the expense of reduced CT image quality, which could be adjusted to the diagnostic needs, low-dose CT of abdomen and lumbar spine can be performed at similar dose to radiography. The aim of the current thesis project was to evaluate low-dose CT of the abdomen and lumbar spine and to compare it with radiography. The hypothesis was that CT would give better image quality and diagnostic information compared to radiography at similar dose levels. Firstly, the diagnostic accuracy of low-dose CT of the abdomen was evaluated. Results showed that low-dose CT of abdomen has a high sensitivity and specificity compared to radiography, i.e., it has higher diagnostic accuracy. Similar results were obtained from our systematic review. Secondly, in a phantom study, an ovine phantom was scanned at various CT settings. The image quality was evaluated to obtain a protocol for the optimal settings for low-dose CT of lumbar spine at 1 mSv. This new protocol was then used in a clinical study to assess the image quality of low-dose CT of the lumbar spine and compare it to radiography. Results showed that low-dose CT has significantly better image quality than radiography. Finally, the impact of Iterative reconstruction (IR) on image quality of lumbar spine CT was tested. Iterative reconstruction is a recent CT technique aimed to reduce radiation dose and/or improve image quality. The results showed that the use of medium strength IR levels in the reconstruction of CT image improves image quality compared to filtered back projection. In conclusion, low-dose CT of the abdomen and lumbar spine, at about 1 mSv, has better image quality and gives diagnostic information compared to radiography at similar dose levels and it could therefore replace radiography.

ENGLISH ABSTRACT: Question: What are the effects of Intermittent Positive Pressure Breathing (with and without a Positive End Expiratory Pressure [PEEP] Valve), compared to deep breathing exercises, on ventilation distribution in high-risk adults following open upper abdominal surgery (UAS)? Design: This study comprised an observational descriptive component as well as a prospective triple blind randomised controlled crossover trial with concealed allocation and patient, assessor and statistician blinding Participants: Seven patients at high risk for postoperative pulmonary complications following UAS Intervention: Deep breathing exercises (DBExs) were compared to Intermittent Positive Pressure Breathing (IPPB), with IPPB further applied with and without a PEEP Valve, using a randomised cross-over design with 30 minute washout duration between periods. Outcome measures: Global and regional impedance changes in the lungs were measured using Electrical Impedance Tomography. Vital signs, visual analogue pain scale (VAS) and modified Borg scale (MBS) were measured pre– and post-intervention. Results: A greater mean global lung impedance change ( Z) was detected with IPPB compared to DBExs (mean difference in Z 2803.8; 95% CI 5189.9 to 8512.5 and 2046 to 96047.9; P<0.01). These changes in lung impedance lasted 30 minutes before returning to baseline. There was no difference in Z when patients received IPPB with 5cmH20 PEEP compared to IPPB with no PEEP. No specific regional ventilation changes were noted. IPPB did not increase VAS, MBS scores or adversely affect vital signs. Conclusion: IPPB is an effective technique to improve lung volumes compared to deep breathing exercises. Further studies are required to investigate the effect of IPPB on clinical outcome.

Dissertação de Mestrado Integrado em Medicina Veterinária
No baço podem ocorrer doenças primárias ou secundárias de origem neoplásica e/ou não-neoplásica. Dada a sua manifestação clínica inespecífica, a abordagem diagnóstica de doença esplénica é baseada na sua morfologia, recorrendo a modalidades imagiológicas, entre as quais a tomografia computorizada (TC). A TC abdominal permite simultaneamente uma avaliação generalizada e pormenorizada das estruturas abrangidas, útil sobretudo na avaliação da extensão de doença neoplásica. Este estudo propôs-se a avaliar a evolução do recurso a TC abdominal no Hospital Escolar Veterinário (HEV) associado à FMV-ULisboa entre o início de 2009 e o fim de agosto de 2018 e caracterizar, quanto à espécie, sexo, idade e raça, a população submetida a exame nesse período (n=294). Pretendeu-se também caracterizar a amostra com alterações esplénicas descritas no estudo de TC (n=63), independentemente da sua relevância clínica e razão de realização do exame. A presença de alteração esplénica mostrou-se associada à espécie canina (n=61) (p<0,001). Reconheceram-se os sinais imagiológicos respetivos às alterações de tamanho, superfície ou contorno, integridade da cápsula e parênquima esplénico nos estudos pré e pós-contraste endovenoso. A presença de lesões do parênquima foi o sinal mais comum (51/63), maioritariamente multifocais (34/51). Para os cães da amostra (n=61), pretendeu-se avaliar a relação entre os diferentes sinais de alteração esplénica e outros concomitantes. Esplenomegalia focal ou deformação da superfície esplénica exibiu-se apenas na presença de lesões parenquimatosas (p=0,01) e na presença de tais lesões foi menos comum a ocorrência de esplenomegalia difusa (p<0,001). Foram ainda identificadas associações entre diferentes tipos de lesões parenquimatosas quanto à sua densidade no estudo pré-contraste e modo de captação de contraste no estudo pós-contraste. Lesões do parênquima hepático ocorreram sobretudo também na presença de lesões do parênquima esplénico (p=0,02). Rutura esplénica implicou sempre alteração peritoneal (p=0,003), especificamente a presença de derrame peritoneal moderado só ocorreu na presença de rutura esplénica (p<0,001). Através da análise de correspondência múltipla identificaram-se sinais imagiológicos mais discriminatórios, que contribuíram para a atribuição de suspeita ou diagnóstico imagiológico de alterações esplénicas neoplásicas, pela presença de lesões esplénicas de densidade heterogénea, captação de contraste heterogénea ou em anel e rutura esplénica; não-neoplásicas, pela presença de lesões esplénicas isodensas e captação de contraste homogénea; ou clinicamente irrelevantes, pela ausência de lesões esplénicas parenquimatosas.
ABSTRACT - IMAGIOLOGICAL SIGNS IN COMPUTED TOMOGRAPHY OF SPLENIC DISORDERS IN DOGS AND CATS - RETROSPECTIVE STUDY (2009-2018) - The spleen can be affected by primary or secondary diseases of neoplastic and/or non-neoplastic origin may occur. Given its unspecific clinical presentation, the diagnostic approach to the splenic disease is based on its morphology, using imaging modalities, including computed tomography (CT). Abdominal CT allows a generalized and detailed evaluation of the scanned structures, especially useful in assessing the extent of neoplastic disease. This study proposes to evaluate the evolution of the abdominal CT use in the Veterinary Teaching Hospital of the FMV-ULisboa between the beginning of 2009 and the end of August 2018 and to characterize, by species, sex, age and breed, the subjected population to the exam during this period (n=294). We also aimed to characterize the sample with splenic changes described on the CT study (n=63), regardless its clinical relevance and the reason for the exam. The presence of splenic findings was associated with the canine species (n=61) (p<0,001). Imaging signs related to changes in size, shape, capsule integrity and splenic parenchyma on both pre and post intravenous contrast studies. The presence of parenchymal lesions was the most common sign (51/63), comprised mostly of multiple lesions (34/51). For the dogs in the sample (n=61), it was intended to evaluate the relationship between the different of types of splenic findings and other concurrent signs. Focal splenomegaly or splenic surface deformity was seen only in the presence of parenchymal lesions (p=0,01), and in the presence of those lesions the occurrence of diffuse splenomegaly was less common (p<0,001). Some associations were also found between the different types of parenchymal lesions relating to their density in the pre-contrast study and pattern of contrast-enhancement in the post-contrast study. Parenchymal lesions in the liver tend to occur mainly in the presence of splenic parenchymal lesions (p=0,02). Splenic rupture always implied the presence of peritoneal alteration (p=0,003), and particularly the collection of peritoneal effusion only occurred in case of splenic rupture (p<0,001). Through multiple correspondence analysis there were identified discriminatory imaging signs that contributed to the suspicion or imaging diagnosis assignment of neoplastic splenic disorder, by the presence of lesions with heterogeneous density or heterogeneous or ring contrast-enhancement pattern and splenic rupture; non-neoplastic splenic disorder, due to the presence of isodense lesions and homogeneous contrast-enhancement pattern; or clinically irrelevante changes, due to the absence of parenchymal splenic lesions.

Background: The previous studies on safety depth of acupuncture points were studied either with Computer Tomography scanning (CT) or with subjective sensation or with autopsy of adults, some focused on dangerous point around neck and back. All the previous studied were among adults. There is no study about the safety depth of acupoint of children reported. Methods: We retrospective studied 219 cases of children with age from 7 (72 months) to 15 (180 months) years old. We use the CT images files to measure the safety depth of 39 abdominal acupuncture points. Those points are CV meridian 12 points, KI meridian 11 points,SP meridian 11 points, GB meridian 2 points, LV meridian 2 points. Results: The safety depth of these 39 acupoints in 7 to 15 years old children significant increase with age, body weight, waist girth, Body Mass Index (BMI). The regression lines of each point significantly determined by the age, waist and body weight of the child. Conclusion: Safety depth of 39 abdominal acupoints in 7 to 15 years old children are significantly increased with age, body weight, waist circumference and BMI. There is no significant difference of the safety depth of acupoints between male and female children.

Abstract:
The aim of this study was: 1) to describe the computed tomographic thoracic and abdominal anatomy in the clinically normal common marmoset; 2) to describe the normal reference range of Hounsfield units (HU) of major abdominal and thoracic organs; 3) to refine the computed tomography (CT) protocol; 4) to compare abdominal CT to other imaging modalities such as radiography and ultrasound (US). Eight clinically healthy mature common marmosets ranging from 12 to 48 months and 235 to 365 g bodyweight were anesthetised and pre- and post-contrast CT examinations were performed using different CT settings. In 3/8 common marmosets radiography was performed at the same time. Diagnostic quality images could be obtained in the common marmoset despite its small size and high respiration rate using a dual slice CT scanner. Quantitative and qualitative assessments of major thoracic and abdominal structures were obtained. The HU of major abdominal and thoracic organs differed from small animals. Representative cross-sectional images were selected and relevant anatomy was labeled. None of the thoracic lymph nodes were detected and separation of individual lung lobes besides the accessory was only occasionally seen. Identification and delineation of abdominal organs greatly improved with i.v. contrast. A high frequency algorithm with edge enhancement proved to be particularly beneficial for the evaluation of thoracic and to a lesser degree abdominal CT. Due to their size and species specific anatomy (also reflected in their different normal range of HU of individual organs), standard small animal CT protocols need to be critically assessed and adapted for exotics, such as the common marmosets. Imaging findings differed from described anatomic findings (such as positioning of kidneys in relationship to lumbar vertebrae) and could either be due to different study population, imply more mobility of kidneys similar to cats, or emphasize that CT might be better for certain aspects of anatomic descriptions than actual anatomy studies, since it is done in vivo versus the traditional post-mortem approach. This study established normal reference ranges for the thoracic and abdominal computed tomographic anatomy of clinically healthy common marmosets, including adapted CT protocols. This baseline study should facilitate CT examinations of marmosets in a clinical set-up and it is anticipated that diagnostic proficiency will be facilitated. The decision to perform advanced imaging is multi-factorial and highly dependent on patient factors, user experience with the modality and species, emotional value to the owner, availability and accessibility of equipment will be important decision criteria in developing decision strategies in clinical settings. Under ideal circumstances US is recommended as the screening tool of choice for the abdomen in the common marmoset. Radiography still plays an important role as a baseline imaging modality for the abdomen, particularly as whole body radiography in the common marmoset, providing simultaneous information about the thorax and the skeletal system; however its limitations must be considered. In cases where further work-up would be required or in certain clinical presentations, CT should be recommended and should always be combined with i.v. contrast.

Abstract:
Introduction: Lambert-Eaton syndrome occurs due to the attack of autoantibodies to voltage-gated calcium channels in the presynaptic terminal of the neuromuscular junction and is usually paraneoplastic. Objectives: Describe the case of a patient with weakness which was investigated for neoplasm. Design and setting: Case report Methods: Analysis of medical record, photographic record of the diagnostic methods and literature review. Case description: Woman, 60 years old, diabetic, hypertensive and ex-smoker, with proximal weakness in the lower limbs for 4 months with paresthesia in the extremities. In 2 months she needed a cane due to frequent falls, followed by proximal weakness of the upper limbs. She lost 8 kg in 4 months. Neurological examination showed hypotrophy in thighs, proximal tetraparesis predominantly in lower limbs and global hyporeflexia. Electroneuromyography showed decreases to repetitive low-frequency stimulation, but significant increases with repetitive high-frequency stimulation and increased amplitude of compound muscle action potentials after effort, suggesting impairment of the neuromuscular junction in the presynaptic topography. She was diagnosed with LambertEaton syndrome. An investigation of paraneoplastic syndrome was carried out, with tumor markers, tomography of the chest, abdomen and pelvis, thyroid ultrasound, mammography and oncotic colposcopy, all without findings of neoplasia. It was proposed a treatment with human immunoglobulin and followup with physiotherapy, occupational therapy and psychology. She showed a significant improvement in strength after starting treatment. Conclusion: Patients with Lambert-Eaton syndrome should be investigated for an underlying neoplasm and followed up periodically, considering the possibility of cancer diagnosis even months or years after the neurological syndrome.

Abstract:
Pregnancy-associated breast cancer (PABC) is defined as a breast cancer diagnosed during pregnancy, lactation, or in the first postpartum year. PABC is a rare complication that occurs in approximately 0.01% to 0.03% of all pregnancies. The difficulty in diagnosis worsens the prognosis. D.G., 29-year-old, female, noted a mass in her right breast in June 2020. One month later with 13+4 weeks’ gestation, she presented to the obstetrics emergency with recurrent episodes of lower back pain. She was released home with pain relief and was instructed to realize a mammography due to the presence of a 4-cm mass on physical examination of the right breast. Patient returned 12 days later with severe low back pain, a BIRADS 4C mammography, and multiple liver lesions in total abdomen ultrasound. Core-needle biopsy demonstrated a stage II invasive ductal carcinoma with hormone receptors positive and human epidermal growth factor receptor 2 positive. There is involvement of the axilla and intramammary lymph nodes. Magnetic resonance imaging of the lower back and sacroiliac joint was performed and found multiple lesions suspected of metastasis in the inferior thoracic vertebrae, lumbar vertebrae, sacrum, ilium, and femurs. Computed tomography (CT) of the thorax identified a 2.3×1.8 cm irregular lesion in the right breast compatible with the primary neoplasm. Chemotherapy was initiated till she was 31 weeks’ gestation. After childbirth, she reinitiates chemotherapy. Three months later, the patient has convulsive episodes. Cranial CT was done and found multiple lesions compatible with brain metastasis, so she initiated brain radiotherapy. PABC can present itself as a challenging situation with nonspecific symptoms and at an advanced stage. Therefore, it is important to have the PABC in our list of differential diagnoses in this patient.
