Métodos diagnósticos cardiovasculares en pacientes con diabetes mellitus. Revisión / Cardiovascular diagnostic methods in patients with diabetes mellitus. A review

Resumen Las enfermedades cardiovasculares constituyen la causa más común de mortalidad en el mundo. Actualmente, la diabetes mellitus tipo 2 (DM2) representa uno de los principales factores de riesgo de eventos adversos cardiovasculares mayores. Los pacientes que las padecen tienen un riesgo cuatro veces mayor de desarrollar insuficiencia cardíaca y una mortalidad de 10 a 12 veces mayor. La ecocardiografía en todas sus modalidades es la mejor herramienta clínica para el diagnóstico de la insuficiencia cardíaca, ya que proporciona imágenes estáticas y dinámicas del corazón que permiten identificar cambios estructurales y funcionales, como alteraciones en las presiones, cambios de flujo, fracción de expulsión del ventrículo izquierdo y remodelación anatómica de las superficies miocárdicas.

Abstract Cardiovascular diseases are the most common cause of mortality in the world. Currently, type 2 diabetes mellitus (T2DM) is one of the main risk factors for major adverse cardiovascular events. T2DM patients have a four-fold higher risk of developing heart failure and 10 to 12 times higher mortality. Echocardiography in all its modalities is the best clinical tool for heart failure diagnosis, since it provides static and dynamic images of the heart that allow to identify structural and functional changes, such as pressure variations, flow changes, left ventricular ejection fraction and myocardial surfaces anatomical remodeling.

Clinical diagnosis and treatment of liver perivascular epithelioid cell neoplasms / 中华肝胆外科杂志

Objective:To analyze the clinical features and prognosis of liver perivascular epithelioid cell neoplasms (PEComa).Methods:The clinical data of 12 patients with liver PEComa diagnosed by pathology at the First Affiliated Hospital of Xi 'an Jiaotong University from October 2011 to November 2021 were retrospectively analyzed. There were 1 male and 11 females, with a median age of 44 (range 20 to 63) years old. The clinical manifestations, laboratory examinations, imaging features, treatment methods, postoperative pathological features and treatment outcomes of these patients were collected and analysed. Postoperative follow-up by telephone or patient's follow-up records.Results:Among the 12 patients with hepatic PEComa, 8 patients (66.7%) were asymptomatic and 11 patients (91.7%) had a single lesion. All patients underwent surgical treatment, including local tumor resection in 10 patients (83.3%) and extended hemihepatectomy in 2 patients (16.7%). Enhanced CT showed the lesion to be a quasi-round homogeneous low-density mass, enhanced in arterial phase with hepatic artery branches in the lesion, and decrease in enhancement degrees in portal vein phase and delayed phase. Postoperative pathology of the lesions in all the 12 patients was benign. Immunohistochemical results showed that the positive rates of melanoma cell markers HMB45, Melan-A and smooth muscle actin were 100.0%(12/12), 83.3%(10/12) and 91.7%(11/12) respectively. The median follow-up period was 27 months, and no recurrence or metastasis was found.Conclusion:Hepatic PEComa occurred commonly in women with obscure symptoms. The lesion was mainly single and it had no correlation with hepatitis. It is easily confused with primary liver cancer and liver metastasis on medical imagings. PEComa expressed markers of both melanocyte and smooth muscle cell, and radical surgical resection resulted in good results.

Imaging findings and clinical analysis of craniopharyngioma / 中国医师进修杂志

Objective:To retrospectively summarize the imaging and clinical features of craniopharyngioma in order to improve the preoperative diagnosis level.Methods:One hundred and twenty-seven patients with craniopharyngioma diagnosed by pathology in Sanbo Brain Hospital, Capital Medical University from March 2019 to June 2021 were selected and the pathological coincidence rate of imaging diagnosis were analyzed.Results:The coincidence rate of MRI diagnosis was 89.3%. The coincidence rate of CT diagnosis was 71.5%. On T 2WI and T 1WI enhanced sequences, the solid portion of the tumor may showed uneven hyperintensity, diffuse striation and spotty hyperintensity. MRI sagittal view was helpful in showing small tumors, but less sensitive to calcification than CT. MRI enhancement was very important, especially for patients with solid lesions. Conclusions:The imaging findings of craniopharyngioma are diverse. Some characteristic manifestations provide important information for the diagnosis and differential diagnosis of craniopharyngioma, which can improve the diagnostic accuracy combined with clinical data.

Hemorrhagic and Non-hemorrhagic Pituitary Apoplexy: Imaging Cohort Analysis.

Introduction: Patients suffering from pituitary apoplexy present with variable clinical symptoms and imaging findings. Imaging findings may differ between hemorrhagic and non-hemorrhagic apoplexy. Our study aimed to better define imaging findings in both hemorrhagic and non-hemorrhagic apoplexy and is the first cohort study to report a comparison of imaging findings in these two groups. Materials and Methods: 311 consecutive patients admitted with pituitary tumors were retrospectively reviewed for clinical and imaging evidence of pituitary apoplexy. 37 operative cases were included in this cohort. A cohort statistical analysis was performed between the two groups using Chi Square, Fisher exact test, logistic regression, ANOVA, and t-test. Results: Imaging analysis demonstrated a significant difference in the hemorrhagic cohort’s Computed Tomography (CT) finding of hyperdensity within the sella (n = 17, 48.5%, p = 0.02) and sellar Hounsfield units (mean 45 versus 38.1, p=0.05). Sellar HU were higher in the hemorrhagic pituitary apoplexy cohort. Similarly, hyperintensity on magnetic resonance imaging was more indicative of patients with hemorrhagic apoplexy according to T1 (p = 0.004), T2 (p = 0.004), and FLAIR (p = 0.04) imaging sequences. No difference was found in patterns of enhancement (p = 0.69) or restriction based on diffusion-weighted imaging (p = 0.54). Gradient echo (n=4) and susceptibility weighted imaging (n=1), while not performed in all patients, demonstrated hemorrhage within a pituitary adenoma in patients where this technique was used. Conclusions: Our study did not demonstrate a unifying imaging feature in non-hemorrhagic apoplexy cases. Hemorrhagic apoplexy was more likely associated with hyperdensity on CT and hyperintensity on T1, T2 and FLAIR MRI sequences. Because of the variation of imaging findings in hemorrhagic and especially non-hemorrhagic apoplexy, imaging appearance inconsistent with hemorrhage should not be used to exclude the diagnosis of apoplexy.

Imaging evaluation of complications after liver transplantation / 临床肝胆病杂志

Liver transplantation is an effective treatment for end-stage chronic liver diseases and acute liver failure. With the rapid development of surgical techniques, organ preservation technology, and pharmacotherapy, patients' survival rates are improved constantly. However, postoperative complications are still major influencing factors for postoperative incidence and mortality rates. Since clinical and laboratory examinations lack specificity and it is difficult to diagnose various postoperative complications, the application of imaging techniques effectively solves such problems. This article summarizes the imaging findings of common complications after liver transplantation, such as vascular complications, biliary complications, liver parenchyma lesions, and postoperative infection, and points out that imaging examinations have significant advantages and can be used for comprehensive evaluation of disease progression.

Objective To explore the clinical manifestations,imaging findings,pathological classification and treatment of congenital cystic adenomatoid malformation (CCAM)of the lung.Methods The clinical features,imaging findings,pathology information,diagnosis,treatment method and its prognosis of children with CCAMconfirmed by ope-ration and pathology were retrospectively analyzed in Yuying Children′s Hospital Affiliated to Wenzhou Medical Univer-sity from August 2006 to August 201 4.Results Eleven patients were boys and 4 patients were girls.One case had a-symptomatic clinical features,1 2 cases had pulmonary infection,1 case had recurrent chest pain,and 1 case had de-pressed deformity in sternum inferior segment.Chest CT scanning indicated that 9 cases had multiple gas cysts at unila-teral side of lung,among which 1 case was of funnel chest and pulmonary sequestration,1 case of huge cyst containing air and fluid at inferior lobe of left lung,and 4 cases of high density lung shadow;CT examination indicated that 1 case had recurrent chest pain and eventration of diaphragm of the right side combined with pulmonary sequestration.All ca-ses were treated by surgical resection,of whom 1 case was given cystectomy and sequestrectomy,diaphragmatic plication respectively,1 case complicated with funnel chest disease underwent lesion pulmonary lobectomy,sequestrectomy and minimally invasive corrective surgery in pectus excavatum (Nuss surgery),and the remaining 1 2 cases received lesion pulmonary lobectomy.All of 1 5 cases recovered well without complications.Pathological classification type of CCAMin-cluded 1 1 cases of type Ⅰ,3 cases of type Ⅱ and 1 case of type Ⅲ,among which 2 cases had pulmonary sequestration. Conclusions CCAMis a rare disease which can be discovered along with pulmonary infection.Multiple gas cysts are the most common imaging findings and the preoperative diagnosis of CCAM is mostly based on chest CT examination. Type Ⅰ and type Ⅱ are the most common pathological classification.The surgical resection should be given early surgi-cal resection and the prognosis is usually good.

The Central Nervous System Involvement in Fabry Disease: A Review

Abstract Fabry disease (FD) is an X-linked, lysosomal storage disorder caused by a mutation in the alpha galactosidase (GLA) gene leading to a deficiency in α-galactosidase A enzyme (α-Gal A) activity, which in turn results in accumulation of glycosphingolipids in different cells. The 2 major clinical phenotypes are the classic severe phenotype and the milder, later onset phenotype. In severe affected males with little or no α-Gal A activity, the onset of acroparesthesias, hypohidrosis, angiokeratomas, and corneal dystrophy is typically observed in childhood or adolescence. With advancing age, progressive multisystem microvasculopathic disease culminates in renal failure, cardiomyopathy, and/or cerebrovascular disease. Patients with later onset have residual enzyme activity and lack of vascular endothelial glycolipid accumulations; thus, they do not present with the early manifestations of the classic phenotype and typically present cardiac or renal disease in the fourth to seventh decade. Although the pathogenesis of cerebral vasculopathy in FD is poorly understood, it can be hypothesized that white matter changes may reflect the pathophysiology of the disease.

Unsuspected colorectal carcinoma on routine abdominopelvic computed tomography

Colorectal carcinoma is a common lethal disease with signs and symptoms that may be nonspecific. Computed tomography (CT) of the abdomen and pelvis with or without contrast is frequently performed for various general abdominal complaints, but unlike CT colonography, the large bowel may not be optimally prepared for evaluation. As such, careful and diligent assessment of the non-prepared colon in all CT images of the abdomen and pelvis is important, as it ensures that incidental colorectal malignancy is not missed, especially in older patients. This article gives an overview of multidetector CT imaging signs and subtle clues to aid in the diagnosis of colorectal carcinoma, as well as their pitfalls.

Eosinophilic Otitis Media: CT and MRI Findings and Literature Review

Eosinophilic otitis media (EOM) is a relatively rare, intractable, middle ear disease with extremely viscous mucoid effusion containing eosinophils. EOM is associated with adult bronchial asthma and nasal allergies. Conventional treatments for otitis media with effusion (OME) or for chronic otitis media (COM), like tympanoplasty or mastoidectomy, when performed for the treatment of EOM, can induce severe complications such as deafness. Therefore, it should be differentiated from the usual type of OME or COM. To our knowledge, the clinical and imaging findings of EOM of temporal bone are not well-known to radiologists. We report here the CT and MRI findings of two EOM cases and review the clinical and histopathologic findings of this recently described disease entity.
