Dental care in patients with periodontal disease and hearing impairment: a scoping review / Atención odontológica en pacientes con enfermedad periodontal y deficiencia auditiva: scoping review

Introduction: Literature shows that individuals with disabilities, including hearing impairment, often suffer from untreated dental caries, poor oral hygiene, and compromised periodontal health, leading to adverse effects on oral health. Objetive: This study aims to analyze current evidence concerning dental care strategies for controlling, managing, and preventing biofilm accumulation in patients with hearing impairment. Materials and Methods: A systematic search was conducted in the databases Scopus, Web of Science, SciELO and PubMed between April and May 2022 to identify articles establishing a relationship between periodontal disease and hearing disability. Full-text articles published in English or Spanish between 2012 and 2022 were included. Results: Seventeen articles met the inclusion criteria and were analyzed. These included cross-sectional studies, cohort studies, clinical trials, case reports, and case-control studies. Most studies reported fair to poor oral health status among individuals. Nine different interventions or management approaches for treating periodontal disease in patients with hearing impairment were identified. Conclusions: The current global evidence on the association between periodontal disease and hearing impairment is very limited. Dentists may need to employ various strategies to address communication barriers, as outlined in this study.

"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.

Applicable techniques for subchondral separation of femoral head necrosis treated by tissue engineering / 中国组织工程研究

BACKGROUND:The appearance of the crescent sign in femoral head necrosis is a"turning point"in the progression of the disease,and repairing and stabilizing the bone-cartilage interface is particularly important in preventing further progression and collapse of the femoral head.Tissue engineering offers potential advantages in the simultaneous repair and integration of the bone-cartilage interface. OBJECTIVE:To review potentially suitable techniques addressing the subchondral separation in femoral head necrosis. METHODS:Relevant articles from January 1970 to April 2023 were searched in PubMed,Web of Science,and China National Knowledge Infrastructure(CNKI)using English search terms"femoral head necrosis,avascular necrosis of femoral head,osteonecrosis of femoral head"and Chinese search terms"femoral head necrosis,subchondral bone,cartilage,integration of cartilage and subchondral bone".A total of 114 articles were included for review and analysis. RESULTS AND CONCLUSION:(1)Structural defects,ischemic and hypoxic environment,inflammatory factors,and stress concentration may cause subchondral separation in osteonecrosis of the femoral head.Subchondral bone collapse and failure of hip-preserving surgery may be associated.Integration of tissue engineering scaffolds with the bone-cartilage interface is one potential approach for treating subchondral separation in osteonecrosis of the femoral head.(2)Current literature suggests that multiphase scaffolds,gradient scaffolds,and composite materials have shown improvements in promoting cell adhesion,proliferation,and deposition of bone and cartilage matrix.These advancements aid in the integration of scaffolds with the bone-cartilage interface and have implications for the treatment of subchondral separation in osteonecrosis of the femoral head.(3)Surface modifications of scaffolds can enhance interface integration efficiency,but they have their advantages and disadvantages.Scaffolds providing different environments can induce differentiation of mesenchymal stem cells and facilitate integration between different interfaces.(4)Future scaffolds for subchondral separation in osteonecrosis of the femoral head are expected to be composite materials with gradient and differentiated biomimetic structures.Surface modifications and stem cell loading can promote integration between the bone-cartilage interface and scaffolds for therapeutic purposes,but further experimental verification is still needed.Challenges include synchronizing scaffold degradation rate with repair progress and ensuring stability between different interfaces.

Correlation between CT Blend Sign and Poor Outcomes after Craniotomy in Patients With Intracerebral Hemorrhage / 医学研究杂志

Objective To explore the effect of head CT blend signs on short-term outcomes in patients with spontaneous supraten-torial intracerebral hemorrhage(ICH)after craniotomy.Methods A total of 435 patients with spontaneous supratentorial ICH who un-derwent craniotomy in the Department of Neurosurgery,Jinyang Hospital Affiliated to Guizhou Medical University from January 2019 to December 2022 were enrolled retrospectively.The patients were divided into the blend sign group(n=105)and control group(n=330)based on the CT features at admission.The general clinical data,imaging data,surgical data,complications and prognosis were collected and compared between the two groups.The outcome was assessed by the mRS(modified Rankin scale)at discharge.Multivariate Logistic regression model was used to analyze the independent correlation between CT blend sign and poor outcomes.Results During the follow-up period,there was no significant differences in the proportion of patients with poor outcomes between the two groups.The poor outcomes after craniotomy was independently correlated with age,smoking history,diabetes history and Glasgow coma scale(GCS)at admission,but not with blend signs.Conclusion Head CT blend signs on admission is not associated with the poor outcomes in patients with sponta-neous supratentorial ICH after craniotomy.

Efficacy of rituximab therapy for 10 patients suffering from systemic lupus erythematosus with intestinal involvement / 中华内科杂志

We retrospectively analyzed therapy efficacy and the adverse reactions of 10 patients suffering from systemic lupus erythematosus (SLE) with intestinal involvement treated with rituximab (RTX). Patients were hospitalized in the Department of Rheumatology and Immunology of the First Medical Center of PLA General Hospital from January 2015 to January 2023. Among the 10 patients, two were men and eight were women. The age of the cohort was (41.9±8.8) years. The age at disease onset was (28.8±9.2) years. The total course of the SLE diagnosis was(109.6±59.9) months. The course of the diagnosis of SLE with intestinal involvement was (89.3±50.2) months. The time from the appearance of intestinal symptoms to the diagnosis of SLE with intestinal involvement was 1.5 (1.0,8.0) months. The time from the diagnosis of SLE with intestinal involvement to RTX use was 13.0 (1.0,46.3) months. Follow-up duration after application of RTX treatment was (55.3±28.4) months. There were five cases of abdominal pain, four cases of abdominal distension, nine cases of diarrhea, three cases of nervous-system involvement, nine cases of lupus nephritis, and seven cases of serositis. All 10 patients underwent computed tomography and radiology of the abdomen. Eight patients had intestinal-wall edema, seven suffered intestinal dilation, four had target signs, three suffered congestion of mesenteric blood vessels, eight had increased mesenteric-fat density, and six had false intestinal obstruction. All 10 patients showed a low level of complement C3 (250-750 mg/L). Nine cases showed a low level of complement C4 (10-90 mg/L). The SLE disease activity index 2000 (SLEDAI-2K) at baseline in 10 patients was 20.5 (17.8, 30.0). After receiving RTX (0.5 g: day 1, day 14, or 375 mg/m 2: day 1, day 14) induction treatment, the intestinal symptoms of 10 cases were relieved completely. Four patients had adverse reactions, of which three received a high-dose glucocorticoid combined with RTX treatment simultaneously. Adverse reactions manifested mainly as a reduced level of IgG and infection with herpes simplex virus in one case, reduced level of IgG and lung infection in one patient, lung infection in one case, and reduced IgG level in one patient. RTX may an efficacious treatment strategy for patients suffering from refractory SLE with intestinal involvement.

5-3. Sign Language Education at Tottori University Faculty of Medicine / 医学教育

The Faculty of Medicine at Tottori University has integrated sign language education into its curriculum since 2008, taking advantage of opportunities arising from curriculum revisions. Through the mandatory course titled “Basic Sign Language,” medical students acquire essential sign language expressions and develop an understanding of the challenges that people with hearing impairments face in society, as well as the necessary accommodations required. In the advanced elective course “Medical Sign Language,” students are taught sign language expressions that are vital for effective communication in medical settings. They also gain insights into the specific difficulties experienced by individuals with hearing impairments in healthcare environments and learn about the appropriate accommodations needed. Owing to these educational efforts, the medical school has produced a number of physicians trained in sign language, enhancing the accessibility and safety of medical services for the hearing impaired. The hope is that sign language education will be adopted by medical schools across the nation moving forward.

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.

Estratégias de comunicação dos profissionais de saúde com pessoas com deficiência auditiva: revisão integrativa / Communication strategies employed by health professionals with hearing impaired people: an integrative review / Estrategias de comunicación de los profesionales de la salud con las personas con discapacidad auditiva: revisión integradora

RESUMO Objetivo: identificar estudos na literatura científica sobre a comunicação dos profissionais de saúde entre pessoas com deficiência auditiva na prestação do cuidado. Método: revisão integrativa realizada em fevereiro/2021, em 14 bases de dados e busca manual, sem recorte temporal, nos idiomas português, inglês, espanhol, através dos descritores Pessoas com Deficiência Auditiva e Profissionais de Saúde e suas variações, sem delimitação de contexto. A análise dos resultados deu-se pela organização em grupos temáticos conforme sua frequência. Resultados: 16 estudos foram selecionados, destacando-se os resultados: uso da escrita e mímica como principais estratégias de comunicação; falta de qualificação dos profissionais para uma comunicação efetiva, sendo o uso de LIBRAS a forma menos utilizada; e, sentimento de insegurança, bloqueio, incapacidade que profissionais vivenciam na comunicação com pessoas com deficiência auditiva. Conclusão: é necessário investir na qualificação dos profissionais de saúde em LIBRAS tornando a comunicação mais eficaz, contribuindo para a melhoria da prática assistencial.

ABSTRACT Objective: to identify studies in the scientific literature on the communication between health professionals and hearing impaired people during care provision. Method: an integrative review carried out in February 2021 in 14 databases and with manual search, without time frame, in Portuguese, English, Spanish and through the Hearing Impaired People and Health Professionals descriptors and their variations, without context delimitation. The results were analyzed by organizing them into thematic groups according to their frequency. Results: a total of 16 studies were selected, with the following results standing out: use of writing and mimicry as main communication strategies; non-qualification of the professionals for effective communication, with the use of LIBRAS as the least used means; and feelings of insecurity, blockage and disability experienced by the professionals in communicating with hearing impaired people. Conclusion: it is necessary to invest in health professionals' qualification in LIBRAS, making communication more effective and contributing to improvements in the care practice.

Urticaria pigmentosa in a 9‐month‐old male: case report

@#Urticaria pigmentosa (UP) is the most common form of cutaneous mastocytosis in children. It can be diagnosed clinically, based on the appearance of numerous brownish macules and papules that are symmetrically distributed, mostly on the trunk and the extremities. Skin biopsy is helpful in establishing the diagnosis. Treatment options generally include antihistamines and/or topical corticosteroids. In most cases, pediatric UP tends to disappear spontaneously before puberty. We present the case of a 9-month-old male with a history of multiple brownish patches and plaques, which started when he was four months old. He was diagnosed with UP based on clinical and histopathologic findings, and was prescribed oral antihistamines and emollients for symptomatic treatment.
