"Penumbra sign" in knee pain: a case of distal femur osteomyelitis

"Penumbra sign" is a characteristic finding in magnetic resonance imaging (MRI) of Brodie's abscess, a rare variant of subacute osteomyelitis. We aimed to discuss the imaging finding penumbra sign that will help in the diagnosis of osteomyelitis and may be useful to clinicians in differential diagnosis. A 26-year-old male patient presented to the emergency department with complaints of pain and limping in the right knee that did not go away. He had a history of arthroscopic debridement and percutaneous fixation surgery due to osteochondral fragment 3 years ago. There were no additional findings in the patient's vital parameters, physical examination, and medical history. X-ray imaging revealed two screws in the distal femur and a well-defined sclerotic rim surrounding a radiolucent lesion anterior to the screws. MRI revealed a lesion in the distal femoral metaphysis with low-density fluid and hyperintense granulation tissue surrounding it. After surgical abscess drainage and local debridement, bone cement was placed in the resulting cavity. Teicoplanin treatment was started. The patient was discharged and complete recovery was achieved in the second month. The diagnosis of osteomyelitis is often missed or confused with bone tumors in non-traumatic cases presenting with persistent bone pain. MRI imaging is frequently used in differential diagnosis, and detection of characteristic imaging signs such as the penumbra sign accelerates the diagnosis. In this context, emergency department clinicians, in particular, should be cautious and not forget that early treatment can be started by recognizing these signs.

RESUMEN: Los intérpretes en Lengua de Señas Chilena (ILSCh) constituyen un recurso para la inclusión, eliminando barreras de estudiantes sordos que manejan la modalidad visual-gestual para comunicarse. Chile tiene normativa que favorece la participación del ILSCh en distintos ámbitos, y este estudio se centró en los intérpretes en contexto escolar, considerando que existe un desconocimiento de los procesos, implementación, resultados, logros y situación laboral. Las interrogantes del estudio fueron: ¿cuál es el estado actual del ILSCh, las trayectorias formativas, el rol y los desafíos de su quehacer? El objetivo general fue describir la figura del ILSCh y los desafíos que enfrenta en su desempeño laboral en contexto escolar, situados en las regiones Metropolitana y Valparaíso, Chile. El enfoque fue cualitativo, interpretativo, diseño fenomenográfico, descriptivo y transeccional, la muestra intencionada por criterios de 24 intérpretes de nivel escolar. Las técnicas de recogida de información fueron: formulario de identificación, entrevista y grupo focal. Se analizaron las transcripciones con el software Atlas TI. Los resultados muestran la diversidad en la formación, centrada en el vocabulario de la lengua, con mínimas líneas del contexto educativo, desconocimiento del rol, solicitudes de tareas fuera de sus funciones y situaciones laborares sin regulación y diversidad de jefaturas.

ABSTRACT: The interpreters in Chilean Sign Language (ILSCh) constitute a resource for inclusion, eliminating the barriers of deaf students who use the visual-gestural modality to communicate. Chile has regulations that favor the participation of the ILSCh in different áreas, and this study focused on interpreters in the school context, considering that there is a lack of knowledge of the processes, implementation, results, achievements and employment situation. The questions of the study were: What is the current state of the ILSCh, its formative trajectories, its role and the challenges of its work? The general objective was to describe the figure of the ILSCh and the challenges it faces in its work performance in the school context, located in the Metropolitan and Valparaíso regions, Chile. The approach was qualitative, interpretative, phenomenographic, descriptive and transactional design, the sample intentional by criteria of 24 school level interpreters. The information collection techniques were: identification form, interview and focus group. The transcripts were analyzed with the Atlas TI software. The results show the diversity in the training, focused on the vocabulary of the language, with minimal lines of the educational context, lack of knowlegde of the role, requests for tasks outside their functions and work situations without regulation and diversity of leadership.

Obstrucción intestinal secundario a vólvulo de sigmoides en un paciente joven Reporte de un caso / Intestinal Obstruction Secondary to Sigmoid Volvulus in a Young Patient. Case report

Resumen El vólvulo de sigmoides ocurre como resultado de una torsión del eje mesentérico colónico, cuenta con una etiología multifactorial y controvertida, de fisiopatología no clara aún. Presenta un cuadro clínico de inicio inespecífico y posteriores signos y síntomas de oclusión intestinal; su diagnóstico se establece mediante tomografía computarizada, con una sensibilidad y especificidad mayor al 90%. El manejo dependerá de la condición clínica del paciente. Caso clínico: Hombre de 29 años con antecedente de síndrome de Asperger. Refirió que desde 7 días previos a su ingreso presentó dolor tipo cólico difuso, asociado a distensión abdominal e intolerancia a la vía oral. Acudió a valoración hospitalaria donde se realizóa tomografía computarizada con niveles hidroaéreos, torsión de arteria mesentérica inferior de aspecto de torbellino. Se realizó laparotomía exploradora a través de la cual se encontró sigmoides dilatado y volvulado, con perforación en la unión rectosigmoidea; se realizó sigmoidectomía con colorectoanastomosis. Al quinto día presentó datos de respuesta inflamatoria con abdomen agudo, por lo que ingresó a laparotomía exploradora donde se encontró dehiscencia de anastomosis; se realizó procedimiento de Hartmann. El paciente presentó choque séptico y falleció a las 24 horas del postquirúrgico. Discusión: La presentación de vólvulo sigmoides generalmente se presenta en personas mayores de 70 años, pocos casos se describen en personas jóvenes y están relacionados con enfermedad de dismotilidad intestinal. El paciente no contaba con factores predisponentes, el diagnóstico se estableció con imágenes características de la enfermedad, como la imagen en torbellino, se decidió manejo quirúrgico con la realización de resección con colorectoanastomosis. Conclusión: La oclusión intestinal por vólvulo sigmoides es una patología infrecuente en jóvenes y de clínica inespecífica. Ante un paciente que presente datos de oclusión intestinal deberá ser abordado de manera apropiada, sobre todo en pacientes en quienes hayan debutado con una clínica insidiosa y persistente de dolor abdominal secundario a oclusión intestinal, sean jóvenes con o sin factores de riesgo.

Abstract Sigmoid volvulus occurs due to a torsion of the colonic mesenteric axis, it has a multifactorial and controversial etiology, and its pathophysiology is not yet clear. Presenting a clinical picture of non-specific onset and later signs and symptoms of intestinal occlusion, its diagnosis is established with computed tomography with a sensitivity and specificity greater than 90%. Management will depend on the clinical condition of the patient. Clinical case: A 29-year-old man with a history of Asperger syndrome. He referred 7 days prior to admission with diffuse cramping pain, associated with abdominal distension and oral intolerance. He went to the hospital for evaluation where a computed tomography was performed with air-fluid levels, torsion of the inferior mesenteric artery with a whirlwind appearance. Exploratory laparotomy was performed, finding a dilated and volvulated sigmoid with perforation at the rectosigmoid junction. A sigmoidectomy with colorectal anastomosis was performed. On the fifth day, he presented data of inflammatory response with acute abdomen, entering exploratory laparotomy finding anastomosis dehiscence, Hartmann procedure was performed. The patient presented septic shock, died 24 hours after surgery. Discussion: The presentation of sigmoid volvulus generally occurs in people older than 70 years, few cases are described in young people and are related to intestinal dysmotility disease, the patient did not have predisposing factors, the diagnosis is established with characteristic images of the disease such as whirlwind image, surgical management is decided by performing resection with colorectal anastomosis. Conclusion: Intestinal occlusion due to sigmoid volvulus is an infrequent pathology in young people and with non-specific symptoms. When faced with a patient presenting evidence of intestinal occlusion, this should be appropriately addressed, especially in patients who have debuted with insidious and persistent symptoms of abdominal pain secondary to intestinal occlusion, whether they are young with or without risk factors.

Assessing the validity of flap motility sign in predicting the extent of anterior capsular tears in phacoemulsification

Capsulorhexis is an integral step of cataract surgery, and continuous curvilinear capsulorhexis is crucial during phacoemulsification to prevent intraoperative complications. However, sometimes during phacoemulsification in complicated and hard cataract cases, rhexis extension may occur, resulting in posterior capsular rent, nucleus drop, cortex drop, and aphakia. It may not always be possible to continue with phacoemulsification in all cases. In this perspective, the authors describe a novel flap motility sign (FMS) to predict the extent of anterior capsular tear during phacoemulsification. A total of 21,678 patients underwent phacoemulsification for three years, from July 2016 to June 2019. One hundred and twenty-one patients had an anterior capsular tear. There were 102 cases (84.3%) with pre-equatorial tears and 19 cases (15.70%) with postequatorial tears. All pre-equatorial flaps were everted and fluttering, and all postequatorial flaps were inverted and nonfluttering. Posterior capsule rupture (PCR) was observed in all 19 cases of postequatorial flaps (100%). No PCR was observed in patients with fluttering and everted flaps (0%). In-the-bag and scleral-fixated intraocular lens implantations succeeded in pre-equatorial and postequatorial tears, respectively. There was no case of a nucleus drop. This study validates FMS as a predictor for identifying the extent of anterior capsular tears, thereby determining the endpoint of safe phacoemulsification and the site for intraocular lens implantation. Pre-equatorial tears allow for the continuation of safe phacoemulsification and in-the-bag intraocular implantation. Postequatorial tears necessitate timely conversion to small-incision cataract surgery or extracapsular cataract extraction.

El estudio de los efectos de la modalidad lingüística en el léxico mental / The study of the effects of linguistic modality on the mental lexicon

Resumen El estudio se cuestiona sobre un abordaje fructífero en el estudio de los efectos de la modalidad lingüística (de señas versus oral) en la organización de la memoria semántica. Para responder la pregunta de investigación, un aspecto central es definir criterios y procedimientos capaces de distinguir entre los factores transportados por la modalidad lingüística de los que le son propios. Entre los primeros, se encuentran la edad de exposición a la lengua natural y su distribución funcional, etaria o geográfica. Entre los aspectos propios de la modalidad se incluyen la iconicidad y el grado de concreción/abstracción de las piezas léxicas. Se sugiere centrarse en el uso de dicho gradiente para evocar dominios conceptuales. Si lo concreto/abstracto es un continuo, entonces hay que preguntarse qué forma de organización es predominante en el léxico mental de las poblaciones señantes u oyentes y qué factores modulan el perfil de esa organización.

Abstract The efforts to understand the relationship of the meaning of a lexical piece to the object to which it refers, the relationship between the lexical pieces and the concepts, and the understanding of the meanings shared between two speakers who use the same lexical pieces have all constituted major problems for the semantic memory models. According to contemporary literature, perceptual-motor, linguistic, and social information have different weights in the formation of concepts, whether concrete or abstract, stored in the aforementioned memory. Regardless of the models developed so far, it is interesting to note that semantic knowledge is represented by various ways of relating the concepts and the types of relationships between them. In this context, studies in sign languages and comparative studies between spoken and sign languages are scarce. Thus, little is known about the effect of linguistic modality on the semantic networks. After all, the theory on semantic networks and norms for the production of features has been grounded on theories of language and its processing adjusted to spoken languages. As the incorporation of the sign language and the Deaf population has shown in other psycholinguistic and linguistic topics, the importance of including these languages and populations, and comparatives with spoken languages, might increase the explanatory power of the theory to account for the universal and contextual aspects of language and its processing. In this effort, there is a latent risk: the linguistic modality can be only a vehicle for more well-known or studied cross-modal variables (e. g., age of acquisition, functional distribution of language, size of the available lexicon, etc.). If it is considered that languages are not stored together, but similar processes can occur in them, it is essential to find out what may be a singular feature of each modality (spoken versus sign) that might ground differentiated processes. Considering the high iconicity of the sign languages and the possibility of a high concreteness of the lexical pieces in the sign language as distinctive features -not collapsible into well-known variables such as the aforementioned-, this article suggests a careful approach to avoid the aforementioned risk in the study of the effects of the linguistic modality (sign versus oral) in the organization of semantic memory. Since perceptual-motor and social information are the main sources of iconicity, a balanced instrument is necessary in the evocation of perceptual-motor, social, and linguistic information. Repeated free word association tasks seem like an appropriate paradigm for a suggested approach. The reasons for this are that, by not censoring the types of response, then free association tasks allow capturing all kinds of concepts (concrete or abstract), all kinds of semantic relationships/organization (paradigmatic versus thematic) and all kinds of processes (comparison versus interaction). This type of task therefore makes it possible to collect meanings related to linguistic information and non-linguistic experience because affective and experiential information is accessible by doing the task in different repetitions. The approach and the tool are exemplified by an ongoing comparative study between Deaf signing and hearing populations. The partial findings of this study also serve to focus on the expected effects of the difference in iconicity and the level of concreteness/abstractness of the lexical pieces of each linguistic modality; namely, the differences between an abstract and a concrete conceptualization of the conceptual domains. Taxonomic and introspective labels might appear as indicative of paradigmatic relationships, of a taxonomic organization, and of underlying comparison processes. On the other hand, the situational and entity labels, indicative of syntagmatic relationships, of a thematic organization and of underlying interaction processes, might suggest a predominantly concrete organization.

THE ‘FEEDING BRONCHUS SIGN‘ IN CAVITARY LUNG LESIONS, ITS EVALUATION WITH COMPUTED TOMOGRAPHY AND A GUARDED OPINION REGARDING PHYSIOTHERAPY

BACKGROUND Bronchiectasis and cavitation are key features of acute and chronic pulmonary infections. Cavitary lesions may carry unfavourable prognosis with regard to complete restoration of pulmonary function in few patients. OBJECTIVES To evaluate type and site of bronchiectasis, its relation with cavity formation on computed tomography and providing an insight to sorting out subjects suited for physiotherapy. A radiological sign-“Feeding bronchus sign” has been discussed with reference to bronchiectasis, its origin, natural course and a suggestion of guarded future management and rehabilitation. METHODS Total 150 chest CT scans with presence of cavity and bronchiectasis were retrospectively reviewed and followed up for type, site of bronchiectasis, signs of active infection, site of cavity and presence of “feeding bronchus sign”. Final diagnosis was confirmed by sputum sample, acid-fast bacillus test or culture or polymerase chain reaction. RESULTS Out of 150 cases, 70 (46%) had chronic and 80 (53%) had active infection. 33 (22%) had solitary and 117 (78%) had multiple cavities. 37 (34.6 %) patients had cylindrical, 11 (7.3 %) had varicose, 27 (18%) had cystic bronchiectasis, 23 (15.3%) had cylindrical and varicose, 19 (12.6%) had cylindrical and cystic and 33 (22%) had all three types. “Feeding bronchus sign” was observed in 102 (68%) patients. Radiological evidence of disease progression was seen in 21 patients, improvement in 19 and no change in 17 on follow-up CT. CONCLUSION Patients with positive “Feeding bronchus sign” are at risk for increased disease transmission and secondary opportunistic infections. Improvement and maintenance of quality of life is ultimate goal of management. Apart from antibiotics, pulmonary rehabilitation also plays an important role in cavitary lung disease

Signo de la cruz en una paciente peruana con ataxia espinocerebelosa tipo 2: reporte de un caso / Hot cross bun sign in a Peruvian patient with spinocerebellar ataxia type 2: A case report

RESUMEN La ataxia espinocerebelosa tipo 2 (SCA2) es una enfermedad neurodegenerativa hereditaria autosómica dominante, causada por una expansión anormal del trinucleótido CAG en el gen ATXN2. La SCA2 se presenta habitualmente en la edad adulta, con ataxia progresiva asociada a neuropatía periférica, alteración de movimientos oculares, parkinsonismo, entre otros síntomas. Exámenes auxiliares aplicables incluyen pruebas bioquímicas, neuroimágenes, como resonancia magnética cerebral, y estudio genético molecular. Describimos, por primera vez en la población peruana, el caso de una mujer de mediana edad con diagnóstico confirmado de SCA2, cuya resonancia magnética cerebral muestra el signo de la cruz (o hot cross bun sign).

ABSTRACT Spinocerebellar ataxia type 2 (SCA2) is an autosomal dominant inherited neurodegenerative disease, caused by an abnormal CAG trinucleotide expansion in the ATXN2 gene. SCA2 usually occurs in adulthood, with progressive ataxia associated with peripheral neuropathy, impaired eye movements, parkinsonism, and other symptoms. Auxiliary exams include biochemical tests, neuroimaging such as brain MRI, and a molecular genetic study. We describe, for the first time in the Peruvian population, the case of a middle-aged woman with a confirmed diagnosis of SCA2, whose brain MRI shows the "Hot Cross Bun Sign".

Pulmonary Hydatid without Liver Involvement: A Case Series

Pulmonary hydatid is not a rare disease. But raising a suspicion for its diagnosis is limited. There are limited approaches for the diagnosis and treatment of the same. We present here four cases of pulmonary hydatid, without liver involvement, with emphasis on how it was misdiagnosed and received multiple treatment and landed into complications. Most of our cases presented with cough, sputum and hemoptysis. For these nonspecific signs and symptoms, patient is generally treated on a different line of diagnosis. Two of the cases were already treated for abscess and fungal infection. One of the patients was on antitubercular treatment. One of our cases was secondarily infected with aspergilloma. One of the cases was referred to oncologist to start chemotherapy. Interestingly, to raise a suspicion, none of our cases had liver involvement. A detailed history revealed expectoration of white salty material in sputum, living with sheep and dog and expectorating grape-like vesicles in sputum. History helped us to put hydatid as one of our differentials. Echinococcal serology was positive in three cases. Only three cases had on-table appearance of hydatid cyst. All four cases underwent surgical management for complete cure. There is need for strong suspicion and a detailed history and proper set of investigations help in timely diagnosis and management of pulmonary hydatid disease.

Métodos: pesquisa qualitativa de natureza descritiva-analítica, utilizando a análise de conteúdo categorial temática. Foi aplicado questionário sociodemográfico e realizada entrevista semiestruturada com 12 profissionais intérpretes de libras, atuantes nas redes de ensino nos níveis fundamental, médio e superior do município de Goiânia, convidados via redes sociais, no primeiro semestre de 2021. Resultados: foram identificadas três categorias temáticas: percepção álgica, percepção de cansaço e atividades de vida diária. Os profissionais estavam trabalhando remotamente devido à pandemia da doença COVID-19, cujo regime permitiu uma flexibilização do processo de trabalho com aulas on-line, eventos, palestras e congressos a partir do domicílio do trabalhador. Houve um aumento expressivo da demanda física e psicológica, devido ao aumento das atividades a serem cumpridas e por estarem ausentes os limites entre ambiente de "trabalho" e "casa". Conclusão: os participantes apresentaram percepções negativas em todos os aspectos avaliados, evidenciando a existência de sobrecarga na atuação como intérprete de língua de sinais.

Abstract Objective: to analyze the perception of musculoskeletal symptoms and their repercussion in the activities of daily living reported by professional Brazilian sign language interpreters (LIBRAS). Methods: descritive-analytical qualitative research, using thematic categorical content analysis. We used a sociodemographic questionnaire and a semi-structured interview with 12 professional LIBRAS interpreters, working in the primary, secondary, and superior education in the municipality of Goiânia. They were invited via social media, in the first half of 2021. Results: we identified three thematic categories: pain perception, perception of tiredness, and activities of daily living. The professionals were working remotely due to the COVID-19 pandemic. This allowed flexibility in the work schedule, with online classes, events, lectures, and congresses participation from the worker's home. Conclusion: the participants had negative perceptions in all aspects evaluated, evidencing an overload in acting as a sign language interpreter in educational activities.

Effectiveness of educational video on deaf people's knowledge and skills for cardiopulmonary resuscitation: a randomized controlled trial / Efectividad de video educativo sobre conocimiento y habilidad de personas sordas para reanimación cardiopulmonar: ensayo controlado aleatorizado / Efetividade de vídeo educativo no conhecimento e habilidade de surdos para ressuscitação cardiopulmonar: ensaio randomizado controlado

ABSTRACT Objective: To analyze the effectiveness of an educational video on deaf people's knowledge and skills about cardiopulmonary resuscitation. Method: A randomized trial, carried out at three schools with 113 deaf people (control group = 57 and intervention group = 56). After the pre-test, the control group was exposed to the lecture, while the intervention group was exposed to the video. The post-test occurred immediately after the intervention and was repeated after 15 days. A validated instrument was used, with 11 questions, presented in video/Libras (to enable understanding by deaf people) and in written/printed form (to record the answers). Results: In the analysis of knowledge, the median of correct answers in the pre-test was similar between the groups (p = 0.635), while the intervention group had a higher accuracy in the immediate post-test (p = 0.035) and after 15 days (p = 0.026). In the skill analysis, the median of correct answers in the pre-test was higher in the control group (p = 0.031). There was no difference in the immediate post-test (p = 0.770), and there was a higher accuracy in the intervention group in the post-test after 15 days (p = 0.014). Conclusion: The video proved to be effective in increasing deaf people's knowledge and skills about cardiopulmonary resuscitation. Brazilian Registry of Clinical Trials: RBR-5npmgj.

DC-SIGN receptor is expressed by cells from cutaneous leishmaniasis lesions and differentially binds to Leishmania (Viannia) braziliensis and L. (Leishmania) amazonensis promastigotes

BACKGROUND Dendritic cells (DCs) specific intercellular adhesion molecule (ICAM)-3-grabbing non integrin receptor (DC-SIGN) binds to subgenera Leishmania promastigotes mediating its interaction with DC and neutrophils, potentially influencing the infection outcome. OBJECTIVES In this work, we investigated whether DC-SIGN receptor is expressed in cells from cutaneous leishmaniasis (CL) lesions as well as the in vitro binding pattern of Leishmania (Viannia) braziliensis (Lb) and L. (L.) amazonensis (La) promastigotes. METHODS DC-SIGN receptor was labeled by immunohistochemistry in cryopreserved CL tissue fragments. In vitro binding assay with CFSE-labeled Lb or La promastigotes and RAJI-transfecting cells expressing DC-SIGN (DC-SIGNPOS) or mock-transfected (DC-SIGNNEG) were monitored by flow cytometry at 2 h, 24 h and 48 h in co-culture. RESULTS In CL lesion infiltrate, DC-SIGNPOS cells were present in the dermis and near the epidermis. Both Lb and La bind to DC-SIGNPOS cells, while binding to DC-SIGNNEG was low. La showed precocious and higher affinity to DC-SIGNhi population than to DC-SIGNlow, while Lb binding was similar in these populations. CONCLUSION Our results demonstrate that DC-SIGN receptor is present in L. braziliensis CL lesions and interact with Lb promastigotes. Moreover, the differences in the binding pattern to Lb and La suggest DC-SIGN can influence in a difference way the intake of the parasites at the first hours after Leishmania infection. These results raise the hypothesis that DC-SIGN receptor could participate in the immunopathogenesis of American tegumentary leishmaniasis accounting for the differences in the outcome of the Leishmania spp. infection.

Awareness of Stroke among University Employees in Kigali, Rwanda: A Cross Sectional Study

Background Awareness of stroke is important for appropriate and timely stroke prevention and management. Objective To assess the level of awareness about the risk factors, signs, and appropriate responses for stroke among university employees in Rwanda. Methods We employed a quantitative descriptive cross-sectional approach. We involved 92 participants, and a self-administered questionnaire to collect data. We computed descriptive statistics and used the Chi-Square test to assess any differences in stroke awareness. Results We found that 12% and 15.2% of the participants were not aware of any risk factor and warning sign of stroke respectively. Regarding the reaction in case a warning sign of stroke was noticed, 9.8% of the participants indicated that they would do nothing or advise the victim to take rest at home. The limited awareness was significantly higher in the administrative than academic employees for both risk factors (p=0.002) and warning signs (p=0.006), but not for the appropriate responses to stroke (p=0.426). Conclusion A significant proportion of the participants were not aware of any stroke risk factor, warning sign and appropriate responses. It is important to conduct further similar studies and implement stroke education interventions in university communities

Consistency between iodine-unstained area and tumor pathological size of endoscopic submucosal dissection specimen in superficial esophageal cancer / 中华消化内镜杂志

Objective:To investigate the consistency between the iodine-unstained area and the pathological size of endoscopic submucosal dissection (ESD) specimens of superficial esophageal cancer.Methods:A retrospective study was performed on data of 32 patients with superficial esophageal cancer who accepted ESD from May 2019 to April 2020 in the First Affiliated Hospital, Zhejiang University School of Medicine. The maximum transverse diameter and maximum longitudinal diameter of the iodine-unstained area were compared with the tumor pathological area. A size difference no more than 0.5 cm was considered as conformity, any difference between 0.5 and 1.0 cm was considered as non-conformity, and any difference no less than 1.0 cm was considered as serious non-conformity. At the same time, pink sign after spraying Lugo solution and the consistency of pink sign area with the iodine free area were observed.Results:A total of 32 patients with 33 lesions were enrolled in this study, including 23 males and 9 females and the age of the patients was 59.5±7.3 years. There were 19 (57.6%) lesions whose size of iodine-unstained area was consistent with the tumor pathological area. These 19 lesions were all positive for the pink sign, and the pink sign area overlapped with the iodine-unstained area. In addition, 4 (12.1%) iodine-unstained areas of the lesions did not match the size of the pathological area, and 10 (30.3%) iodine-unstained areas of the lesions were seriously inconsistent with the size of the pathological area. These 14 (42.4%) lesions were all positive for pink sign, and the pink sign area was significantly smaller than the iodine-unstained area. Among the 14 discordant lesions, 2 lesions underwent ESD according to the iodine-unstained area, which resulted in excessive resection and postoperative stenosis.Conclusion:Determining the extent of superficial esophageal cancer by iodine-unstained areas before ESD may lead to excessive resection of the lesions, which is related to the fact that the iodine-unstained areas of the lesions are sometimes significantly larger than the pink sign areas. Therefore, in order to achieve precise treatment, endoscopists can choose the iodine-unstained area with positive pink sign as the first choice for resection.

Research progress of ultra-high field strength 7.0 T magnetic resonance imaging in multiple sclerosis / 中华神经科杂志

Multiple sclerosis (MS) is one of the demyelinating diseases of the central nervous system, and its pathogenesis is still unclear. Magnetic resonance imaging (MRI) is an effective tool for the diagnosis and monitoring of MS, and the identification of MS lesions is increasingly updated with the development of technology. In recent years, 7.0 T ultra-high field MRI has been widely used in MS. This review will make an overview of the research progress of 7.0 T ultra-high field MRI in MS in recent years.

Quantitative susceptibility mapping of the substantia nigra subregions in relapsing-remitting multiple sclerosis patients / 中华放射学杂志

Objective:To investigate the distribution of iron deposition in the substantia nigral (SN) subregions on quantitative susceptibility mapping (QSM) and the change of swallow tail sign (STS) in patients with relapsing-remitting multiple sclerosis (RRMS) of different disease stages.Methods:The clinical and imaging data of 53 patients with RRMS (case group) diagnosed at the First Hospital of Chongqing Medical University from November 2019 to December 2021 were retrospectively analyzed. The case group was divided into 0-5 years subgroup, 6-10 years subgroup, and >10 years subgroup according to the disease duration; another 37 age-and gender-matched healthy volunteers were recruited as the control group during the same period. All subjects underwent MRI and QSM reconstruction. First, the SN was divided into four subregions: rostral anterior-SN (aSNr), rostral posterior-SN (pSNr), caudal anterior-SN (aSNc), and caudal posterior-SN (pSNc) on the QSM, and the quantitative susceptibility value (QSV) of each subregion was measured, and then the STS of the SN was observed and scored on the susceptibility weighted imaging (SWI) generated by post-processing. ANOVA was used to compare the differences in the QSV of each subregion of SN among the groups, and the probability of abnormal STS was compared using the χ 2 test. Spearman′s test was used to analyze the correlation between the QSV of each subregion of SN and the STS score. Results:The differences in QSV of aSNr, pSNr, aSNc, and pSNc were statistically significant among the 0-5 years subgroup, 6-10 years subgroup,>10 years subgroup of RRMS patients and the control group ( P<0.05). The QSV of aSNr, pSNr, and aSNc in 0-5 years subgroup was higher than those in the control group ( P was 0.039, 0.008, 0.039, respectively). The QSV of aSNr, aSNc, and pSNc in the 6-10 years subgroup were higher than those in the 0-5 years subgroup ( P was <0.001, 0.020, 0.015, respectively). The QSV of the aSNc, pSNc in >10 years subgroup were lower than those in the 6-10 years subgroup ( P=0.037, 0.006). The QSV of aSNr, pSNr in >10 years subgroup were higher than those in the control group ( P was <0.001, 0.001). There were 7 cases of abnormal STS in the 0-5 years subgroup, 11 cases in the 6-10 years subgroup, 12 cases in >10 years subgroup, and 9 cases in the control subgroup, and there was a statistically significant difference in the probability of abnormal STS among the subgroups of the RRMS patients and the control subgroup (χ 2=16.20, P=0.011). Both the scores of STS in the 6-10 years subgroup and >10 years group were positively correlated with the QSV in pSNc ( r s=0.65, P=0.006; r s=0.48, P=0.045). Conclusions:In RRMS patients, SN iron deposition is concentrated on aSNr, pSNr, and aSNc in the 0-5 years subgroup and on aSNr, aSNc and pSNc in the 6-10 years subgroup. The QSVs of all SN subregions have a downward trend in >10 years subgroup compared with that in the 6-10 years subgroup. Both the QSVs of the pSNc in the 6-10 years group and >10 years group are positively related to STS scores. These help explore the potential progression pattern of SN iron deposition in RRMS patients and the cause of abnormal STS in RRMS patients.
