RESUMO

Introdução: A bichectomia é um procedimento cirúrgico que remove parte do corpo adiposo bucal não apenas para fins estéticos, mas também funcionais, limitando o trauma recorrente na região jugal. A correta indicação cirúrgica e o auxílio de exames de imagem são essenciais para o planejamento cirúrgico e seleção da técnica a ser utilizada, minimizando as taxas de complicações e alcançando resultados seguros e satisfatórios. Objetivo: Relatar dois casos clínicos em que a bichectomia foi realizada, enfatizando a importância da ultrassonografia pré-operatória na determinação do volume do corpo adiposo bucal e abordando duas técnicas cirúrgicas. Relato de casos clínicos: Duas pacientes do sexo feminino (18 e 32 anos), normosistêmicas, relataram queixas de insatisfação estética com o contorno arredondado da face, além de trauma constante na mucosa jugal. Ao exame clínico, as pacientes apresentavam mucosa jugal de volume aumentado e traumatizado. A bichectomia foi realizada pelo acesso de Matarasso e pelo fundo de sulco. Conclusão: a ultrassonografia mostrou-se eficiente no planejamento cirúrgico da bichectomia, favorecendo a retirada do corpo adiposo da bochecha de forma previsível, rápida e segura. As duas técnicas cirúrgicas foram eficazes para remoção do corpo adiposo bucal(AU)


Introduction: Bichectomy is a surgical procedure that removes part of the buccal fat pad not only for esthetic but also functional purposes, limiting recurrent trauma in the jugal region. The correct surgical indication and the aid of imaging examinations are essential for the surgical planning and selection of the technique to be used, minimizing complication rates and achieving safe and satisfactory results. Objective: To report two clinical cases in which bichectomy was performed, emphasizing the importance of preoperative ultrasonography in determining the volume of the buccal fat pad. Report of clinical cases: Two female patients (18 and 32 years), normosistemic, reported complaints of aesthetic dissatisfaction with the rounded contour of the face, in addition to a constant complaint of trauma to the jugal mucosa. At the clinical examination, the patients presented jugal mucosa of increased and traumatized volume. A bichectomy was performed by Matarasso access and by the furrow fund. Conclusion: ultrasonography proved to be efficient in assisting the surgical planning of bichectomy, favoring the removal of the buccal fat pad in a predictable, fast and safe way. The two surgical techniques were effective for removal of the buccal fat pad(AU)

RESUMO

Infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) results in coronavirus disease 2019 (COVID-19), which was declared an official pandemic by the World Health Organization on March 11, 2020. The infection has been reported in most countries around the world. As of August 2020, there have been over 21 million cases of COVID-19 reported worldwide, with over 800 000 COVID-19-associated deaths. It has become apparent that although COVID-19 predominantly affects the respiratory system, many other organ systems can also be involved. Imaging plays an essential role in the diagnosis of all manifestations of the disease, as well as its related complications, and proper utilization and interpretation of imaging examinations is crucial. With the growing global COVID-19 outbreak, a comprehensive understanding of the diagnostic imaging hallmarks, imaging features, multisystemic involvement, and evolution of imaging findings is essential for effective patient management and treatment. To date, only a few articles have been published that comprehensively describe the multisystemic imaging manifestations of COVID-19. The authors provide an inclusive system-by-system image-based review of this life-threatening and rapidly spreading infection. In part 1 of this article, the authors discuss general aspects of the disease, with an emphasis on virology, the pathophysiology of the virus, and clinical presentation of the disease. The key imaging features of the varied pathologic manifestations of this infection that involve the pulmonary and peripheral and central vascular systems are also described. Part 2 will focus on key imaging features of COVID-19 that involve the cardiac, neurologic, abdominal, dermatologic and ocular, and musculoskeletal systems, as well as pediatric and pregnancy-related manifestations of the virus. Vascular complications pertinent to each system will be also be discussed in part 2. Online supplemental material is available for this article. ©RSNA, 2020.

RESUMO

OBJECTIVES: To assess the diagnostic yield of point-of-care ultrasound imaging in patients suspected of having noncritical severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection but no apparent changes on a chest radiograph. MATERIAL AND METHODS: Cross-sectional analysis of a case series including patients coming to an emergency department in March and April 2020 with mild-moderate respiratory symptoms suspected to be caused by SARS-CoV-2. A point-of-care ultrasound examination of the lungs was performed on all participants as part of routine clinical care. Ultrasound findings were compared according to the results of SARS-CoV-2 test results. RESULTS: Fifty-eight patients with a median (interquartile range) age of 44.5 (34-67) years were enrolled; 42 (72.4%) were women. Twenty-seven (46.5%) had confirmed SARS-CoV-2 infection. Ultrasound findings were consistent with interstitial pneumonia due to coronavirus disease 2019 (COVID-19) in 33 (56.9%). Most were in cases with testconfirmed COVID-19 (100% vs 22.2% of cases with no confirmation; P < .001). The most common ultrasound findings in confirmed COVID-19 cases were focal and confluent B-lines in the basal and posterior regions of the lung (R1, 85.2%; R2, 77.8%; L1, 88.9%; and L2, 88.9%) and associated pleural involvement (70.4%, 70.4%, 81.5%, and 85.2%, respectively). The sensitivity of point-of-care ultrasound in the diagnosis of COVID-19 was 92.6% (95% CI, 75.7%-99.1%). Specificity was 85.2% (95% CI, 66.3%-95.8%); positive predictive value, 75.8% (95% CI, 59.6%- 91.9%); negative predictive value, 92% (95% CI, 74.0%-99.0%); and positive and negative likelihood ratios, 6.2 (95% CI, 6.0-6.5) and 0.1 (95% CI, 0.1-0.1), respectively. CONCLUSION: Point-of-care lung ultrasound could be useful for the diagnosis of noncritical SARS-CoV-2 infection when chest radiographs are inconclusive.

RESUMO

INTRODUCTION: Carcinoid tumor is one of the most frequent neuroendocrine tumors, and the majority of which are usually observed in the lungs and gastrointestinal tract. The prevalence of ovarian carcinoids is merely 0.1% in ovarian neoplasms and 1% in carcinoid tumors. We described 2 rare cases in our hospital of primary ovarian carcinoid (POC), causing carcinoid syndrome (CS) of the diarrhea, constipation, and carcinoid heart disease. Besides, we also reviewed related literatures about its origin, variant, clinical manifestation, diagnosis methods, pathological features, treatment strategies and prognosis from 2009 to 2019. PATIENT CONCERNS: Case 1 was a 61-year-old postmenopausal woman and presented with diarrhea, abdominal pain, enlargement, bloating and dizziness. Case 2 was a 49-year-old patient who complained of constipation, abdominal pain, bloating, and headache. DIAGNOSIS: Both patients were diagnosed as primary ovarian carcinoid, insular type. INTERVENTIONS: Total abdominal hysterectomy (TAH), bilateral salpingo-oophorectomy (BSO), omentectomy, pelvic lymphadenectomy, and appendectomy without chemotherapy were performed in case 1. Cervix resection, right salpingo-oophorectomy, appendectomy, and pelvic lesion resection with chemotherapy was conducted in case 2. OUTCOMES: Both patients achieved satisfactory treatment effects. The follow-up period was 18 and 17 months in case 1 and case 2, respectively. Case 1 encountered carcinoid heart disease and received percutaneous transluminal coronary angioplasty (PTCA) postoperatively. Case 2 suffered multiple metastases postoperatively. However, after effective treatment, both patients were in good condition during follow-up duration. CONCLUSION: POC is an extraordinarily rare disease, and commonly with a satisfactory outcome. TAH+BSO with or without postoperative chemotherapy has been considered as an acceptable treatment strategy for POC patients.

RESUMO

RATIONALE: Foreign bodies are frequently ingested, but only approximately 1% of them cause perforation. Perforations in the lesser curvature of the stomach are exceedingly rare. Here, we report a case of gastric perforation in the lesser curvature caused by a foreign body. The patient presented to the clinic complaining of abdominal skin swelling and reddening with upper abdominal discomfort as the initial symptoms. PATIENT CONCERNS: An 83-year-old female presented with a mass in the middle of the epigastrium for 10 days. Physical examination found an apparent local tenderness and inflammatory mass in the upper abdominal wall. Her body temperature was normal (37.5°C) and the white blood cell count was elevated (8.12 × 10/L [reference value 3.5-9.5 × 10/L]). DIAGNOSES: The ultrasound examination of the abdomen revealed a 4 cm strip-like hyperechoic object entangled in the muscles of the abdominal wall. The computed tomography scan revealed a thin strip of bone-like hyperdense shadow. Intraoperative findings showed a sharp fishbone protruding from the lesser curvature of the stomach into the abdominal cavity, part of which remained in the gastric cavity. The postoperative pathological report revealed chronic suppurative inflammation with abscess and sinus canal formation. INTERVENTIONS & OUTCOMES: The patient underwent a gastric foreign body removal with partial gastrectomy. Anti-inflammatory treatment post-surgery rapidly relieved the patient's symptoms of discomfort in the upper abdomen. At the 1-month follow-up, the patient showed no discomfort in the upper abdomen and the inflammatory mass was no longer present. LESSONS: A foreign body had penetrated through the lesser curvature of the stomach, an area with a flat gastric wall, which occurs infrequently. In such cases, computed tomography is the gold standard for diagnosis of foreign bodies in the digestive tract. Ultrasound can also be used as a supplemental diagnostic technique. It is recommended that people who wear dentures should exercise caution while eating, especially when the food contains bones.

RESUMO

This study aimed to investigate the associations between the sonographic findings and duration of symptoms in children with pilomatricoma.This study included 86 children with 95 lesions confirmed to be pilomatricoma after pathological examination. The associations between symptom duration and sonographic observations, including the presence or absence of peritumoral hyperechogenicity, calcification, and vascularity were investigated. The internal echogenicity of each pilomatricoma was scored using a 5-point scale based on echogenic spots and calcification with posterior acoustic shadowing. The Mann-Whitney U and Kruskal-Wallis tests were used for statistical analysis.We found that the absence of peritumoral hyperechogenicity and severity of calcification were associated with increased symptom duration. Calcification, (present, 19.19 ±â€Š18.99 months vs absent, 4.31 ±â€Š3.24 months; P < .01) and peritumoral hyperechogenicity (present, 5.02 ±â€Š5.80 months vs absent, 16.17 ±â€Š18.24 months; P < .01), and grade of internal echogenicity (grade 0/1/2/3/4 = 3 months [1 patient]/4.33 ±â€Š3.26 months [range, 1-12]/4.57 ±â€Š3.46 months [range, 2-12]/10.89 ±â€Š9.17 months [range, 3-28]/35.27 ±â€Š19.16 months [range, 9-60], respectively; P = .01 and <.01) were associated with significant differences in symptom duration. There were no significant between-group differences in vascularity (6.01 ±â€Š7.24 months; range, 1-48 vs 15.50 ±â€Š19.12 months; range, 1-60; P = .08).Pilomatricomas with a relatively short symptom duration were more likely to exhibit peritumoral hyperechogenicity and calcification with less severe posterior acoustic shadowing compared to lesions with a longer symptom duration. These sonographic findings provided useful information that facilitated the correct and rapid diagnosis of pilomatricoma.

RESUMO

INTRODUCTION: The market for dietary supplements in the sports sector has been growing rapidly for several years, though there is still lacking evidence regarding their claimed benefits. One group is that of nitric oxide increasing supplements, so-called "NO-boosters," which are claimed to improve the supply of oxygen and nutrients to the muscle by enhancing vasodilation.The aim of this study was to investigate 3 of these supplements in healthy male athletes for their muscle perfusion-enhancing potential using contrast-enhanced ultrasound (CEUS). METHODS: This placebo-controlled, double-blind, randomized cross-over trial will be carried out at the Center for Orthopedics, Trauma Surgery and Spinal Cord Injury of the University Hospital Heidelberg. Three commercial NO enhancing products including 300 mg of the specific green tea extract VASO6 and a combination of 8 g L-citrulline malate and 3 g L-arginine hydrochloride will be examined for their potential to increase muscular perfusion in 30-male athletes between 18 and 40 years and will be compared with a placebo. On each of the 3 appointments CEUS of the dominant biceps muscle will be performed at rest and after a standardized resistance training. Every athlete receives each of the 3 supplements once after a wash-out period of at least 1 week. Perfusion will be quantified via VueBox quantification software. The results of CEUS perfusion measurements will be compared intra- and interindividually and correlated with clinical parameters. DISCUSSION: The results of this study may help to establish CEUS as a suitable imaging modality for the evaluation of potentially vasodilatory drugs in the field of sports. Other supplements could also be evaluated in this way to verify the content of their advertising claims.

RESUMO

RATIONALE: Mycobacterium tuberculosis (TB) remains a serious threat in developing countries. Primary isolated hepatic tuberculosis is extremely rare. Because of its non-specific imaging features, noninvasive preoperative imaging diagnosis of isolated hepatic tuberculoma remains challenging. PATIENT CONCERNS: A 48-year-old man was admitted to our hospital due for suspected liver neoplasm during health examination. DIAGNOSES: The tests for blood, liver function, and tumor markers were within normal range. Preoperative ultrasonography (US) showed a hypoechoic lesion with a longitudinal diameter of 2.5 cm in segment six of liver. It exhibited early arterial phase hyperenhancement and late arterial phase rapid washout in contrast-enhanced US. It demonstrated hyperintensity in T2-weighted magnetic resonance imaging and partly restricted diffusion in diffusion-weighted imaging. For this nodule, the preoperative diagnosis was small hepatocellular carcinoma (HCC). INTERVENTIONS: Laparoscopic hepatectomy was performed. Intraoperative extensive adhesion in the abdominal cavity and liver was found. The lesion had undergone expansive growth. OUTCOMES: Microscopically, a granuloma with some necrosis was detected. With both acid-fast staining and TB fragment polymerase chain reaction showing positive results, TB was the final histology diagnosis. After surgery, the patient declined any anti-TB medication. During the follow-up, he had no symptoms. In the sixth month after surgery, he underwent an upper abdominal US. It showed no lesions in the liver. LESSONS: Because of non-specific imaging findings and non-specific symptoms, a diagnosis of isolated hepatic TB is difficult to make, especially for small lesions. A diagnosis of HCC should be made cautiously when small isolated lesions in the liver are encountered, especially in patients without a history of hepatitis and with negative tumor markers.

RESUMO

Adrenal glands are often not examined in abdominal ultrasound because it is thought that the adrenal glands cannot be visualized. The normal right adrenal gland can be represented in most cases and the left one very often. Sonography makes an important contribution to the diagnosis of adrenal diseases. In addition to bleeding and tuberculosis, there are benign tumors (adrenal adenomas), pheochromocytomas, and adrenal carcinomas. There are also adrenal metastases and lymphomas.

RESUMO

Elevated liver function tests - as incidental finding in general practice Abstract. In general practice, elevated liver function tests are found in 25 % of patients presenting with unspecific symptoms or during a routine health checkup. Approximately 2.5 % of the general population are expected to show elevated values. Conversely, liver disease can present without abnormal liver function tests. Liver disease is not only frequent but may also imply a significant mortality. Worldwide its prevalence is steadily rising, and liver disease has become the fifth leading cause of death. Responsible for the rapidly increasing prevalence are primarily non-alcoholic fatty liver disease (NAFLD), alcohol-related liver disease (ARLD) and viral hepatitis. Due to the large range of possible differential diagnoses and the coexistence of aetiologies liver diseases represent a diagnostic challenge with important prognostic implication. In case of elevated liver function, a detailed medical history and a thorough clinical examination should be performed first. This allows narrowing down possible causes to the few most likely differential diagnoses. Subsequently, depending on the level of elevated liver function and the clinical presentation as hepatitis or cholestasis, screening tests for differential liver diseases are performed. Laboratory diagnostics and obligatory ultrasound scan can be supplemented by non-invasive methods (e. g. elastography, MRI / MRCP / CT) and in selected cases invasive methods (liver biopsy, ERCP). In the following article we delineate the diagnostic approach to elevated liver function tests using algorithms.

RESUMO

Presented herein is a clinical case report regarding successful treatment of a trophic ulcer of the right tibia by means of endovenous mechanochemical ablation of the great saphenous vein using the FlebogrifTM device. According to ultrasonography findings, the patient was found to have insufficiency of the saphenofemoral junction, axial truncal reflux, and the absence of incompetent perforator veins in the area of trophic disorders. Taking into account the clinical and ultrasound picture of the disease, the decision was made on the feasibility of performing crossectomy and retrograde mechanochemical ablation of the great saphenous vein. The chosen modality of the invasive intervention did not require tumescent anesthesia, allowed a catheter to be placed under the ulcer bed and, unlike thermal methods, excluded the risk of damage to the subcutaneous nerves and soft tissues. The operation made it possible to eliminate pathological truncal reflux along the entire length, which contributed to rapid healing of the trophic ulcer, relief of varicose disease symptoms, and significant improvement of the patient's quality of life. This clinical case report indicates the possibility of application of retrograde endovenous mechanochemical ablation in a patient with varicose disease, axial reflux and open venous ulcer (C6) and warrants further research in this direction.

RESUMO

Sjögren Syndrome is an autoimmune disorder presenting as Sicca syndrome (dry-eye, dry mouth) and most often multiorgan involvement with various clinical manifestations. The diagnostic criteria defined by the American College of Rheumatology (ACR) and the European League Against Rheumatism (EULAR) include biologic, histologic parameters and functional measurements. Part of this workup can be performed by the ENT specialist. It encompasses minor salivary gland biopsy, sialometry, Schirmer lacrymal test and major salivary gland ultrasound. These tests and their performances are described. The growing importance of major salivary gland ultrasound as a follow-up and diagnostic tool is also discussed in this article.

RESUMO

PURPOSE: To explore the sonographic appearance of leukoplakia in non-masticatory oral mucosa, classifying mucosal leukoplakia according to the characteristics of sonogram, and providing reference for clinical diagnosis and treatment. METHODS: Eighteen patients (24 lesions) were diagnosed as oral leukoplakia at the Department of Oral Mucosal Diseases, Shanghai Ninth People's Hospital. The lesions were located in the tongue, floor of mouth, buccal mucosa and libial mucosa. Before the biopsy was taken, intra-oral path ultrasound was performed at the Department of Ultrasound to observe the lesion's extent, continuity, presence or absence of keratinization, the thickness of each layer in the epithelium, and color doppler flow imaging of the lesions. Quantitative analysis software 'Qontraxt' was used to randomly measure the relative echo intensity of the mucosal surface in leukoplakia areas, and summarize the keratinization type. SPSS 25.0 software package was used for statistical analysis of the data, and paired t test was used for inter-group comparison of the data. RESULTS: Oral leukoplakia sonograms showed that the epithelial layer appeared keratinization, the epithelial was thickened, and the echo was enhanced. The stratum intermedium showed a low echo thickening band, and the echo of partial lesions' surface decreased or the blood flow signal in oral mucosa increased. The hyperechoic band in the leukoplakia area was significantly thickened (P<0.001), and the echo was enhanced, with the tongue and buccal mucosa being the most significant. The hypoechoic band was significantly thicker (P<0.001), with the buccal mucosa and labial mucosa being the most significant. The surface and stratum corneum echo intensity values were determined by Qontraxt quantitative analysis software to determine whether there were keratinization and the keratinization types. The echo intensity values was 43.28±9.33 in non-OLK area, 92.88±3.12 in OLK with orthokeratosis, and 84.75±5.76 in OLK with parakeratosis. CONCLUSIONS: Ultrasound imaging can effectively define mucosal leukoplakia and measure the thickness of each layer in the epithelium. In addition, special adjoint changes such as ulcers, infections and cancerous changes can be detected. Intraoral ultrasonic imaging can provide imaging evidence for clinical diagnosis, treatment planning and post-treatment follow-up and contribute to avoid unnecessary mucosal iatrogenic injury or recurrence of disease after treatment.

RESUMO

COVID-19, caused by SARS-CoV-2, has resulted in a global pandemic recently. With no approved vaccination or treatment, governments around the world have issued guidance to their citizens to remain at home in efforts to control the spread of the disease. The goal of controlling the spread of the virus is to prevent strain on hospitals. In this paper, we focus on how non-invasive methods are being used to detect COVID-19 and assist healthcare workers in caring for COVID-19 patients. Early detection of COVID-19 can allow for early isolation to prevent further spread. This study outlines the advantages and disadvantages and a breakdown of the methods applied in the current state-of-the-art approaches. In addition, the paper highlights some future research directions, which need to be explored further to produce innovative technologies to control this pandemic.

RESUMO

OBJECTIVE: To evaluate the feasibility of ultrasound in diagnosis of chronic paracolic inflammatory mass in patients with diverticular disease. MATERIAL AND METHODS: We analyzed ultrasonic findings in 216 patients with chronic inflammatory complications of colonic diverticular disease. Chronic paracolic inflammatory mass as the most common and significant chronic complication of diverticular disease was analyzed in 116 patients. Ultrasonic findings were compared with specimen assessment, intraoperative data, irrigoscopy, colonoscopy, endoscopic ultrasound and computed tomography data. RESULTS: Sensitivity of ultrasound for diagnosis of chronic paracolic inflammatory mass was 76,7%, specificity - 100%, overall accuracy - 87,5%. CT and endoscopic ultrasound were the most informative among different diagnostic tools (sensitivity 79,6% and 77,8%, respectively). CONCLUSION: Ultrasonic examination and computed tomography are the most valuable methods for diagnosis of chronic paracolic inflammatory mass in patients with diverticular disease. Ultrasound is a first-line method for diagnosis and follow-up of complicated diverticular disease due to its availability, safety and unnecessary special preparation of patients.

RESUMO

COVID-19 pneumonia produces a heterogeneous array of clinical, biochemical, and radiological findings. Over the last few months of global hurry to optimize a testing strategy, it has been suggested that bedside point-of-care lung ultrasound may have a diagnostic role. We present 3 patients with RT-PCR nasopharyngeal swab-confirmed COVID-19 pneumonia, who had an admission plain chest film reported to be normal by a consultant radiologist, but with significant sonographic abnormalities on bedside ultrasound performed within 24 hours of the chest radiograph. Lung ultrasound may better correlate with the oxygen requirement and overall condition of the patient than chest radiographs - a pertinent consideration given the imminent advance of the pandemic into resource-poor zones where timely access to roentgenological imaging may be sparse.
