Alcohol consumption during pregnancy by women from southern Brazil: a cross-sectional study.

BACKGROUND: Some maternal characteristics are related to alcohol intake during pregnancy, which irreversibly compromises the maternal-fetal binomial integrity. OBJECTIVES: To identify the frequency, impact, and factors associated with alcohol consumption during pregnancy. DESIGN AND SETTING: A cross-sectional study was performed at the Hospital Materno Infantil Presidente Vargas (HMIPV) in Porto Alegre/RS between March and December 2016. METHODS: A structured questionnaire was administered along with a medical records review. They refer to the maternal sociodemographic and gestational status, alcohol consumption patterns, and characteristics of the fetus/newborn. In the statistical analysis, P values < 0.05 were considered significant. RESULTS: The frequency of alcohol intake was 37.3%; this was characterized by the consumption of fermented beverages (89.3%), especially during the first trimester (79.6%). Risky consumption (high and/or early) occurred for 30.2% of participants. Risk factors associated with maternal alcohol consumption during pregnancy were tobacco use (P < 0.001) and abortion attempt (P = 0.023). Living with a partner (P = 0.002) and planning pregnancy (P = 0.009) were protective factors. Risky consumption was related to all of the aforementioned variables as well as threatened abortion (P = 0.023). CONCLUSIONS: Alcohol intake during pregnancy is common and affects nearly one-third of pregnant women. Knowledge of the population at risk and protective factors is essential for the development of campaigns that seek to reduce consumption and, therefore, its consequences for the mother and fetus.

Patients' prognosis with congenital heart disease followed by ten years: survival and associated factors.

OBJECTIVE: To evaluate the prognosis and influence of associated factors in patients with congenital heart disease admitted for the first time to the Intensive Care Unit of the Hospital da Criança Santo Antônio/Irmandade da Santa Casa de Misericórdia de Porto Alegre, especially those factors associated with death. METHODS: Patients were prospectively and consecutively allocated over a period of one year (August 2005 to July 2006). Now, 15 years after the initial selection, we collected data from these patients in the database of the Cytogenetics Laboratory of the Universidade Federal de Ciências da Saúde de Porto Alegre and in the medical records of the hospital. RESULTS: Of the 96 patients, 11 died and 85 were alive until 20 years old. Four patients died in the Intensive Care Unit. The survival probability up to 365 days of life was 95.8%. The survival assessment identified that the deaths occurred mainly before the patients completed one thousand days of life. We found that complex heart disease was independently associated with an odds ratio of 5.19 (95% confidence interval - CI:1.09-24.71; p=0.038) for death. CONCLUSIONS: Knowledge about the factors that interfere with the prognosis can be crucial in care practice planning, especially considering that congenital heart disease is an important cause of mortality in the first year of life.

RESUMO Objetivo: Avaliar o prognóstico e a influência de fatores associados em pacientes com cardiopatia congênita internados pela primeira vez na Unidade de Terapia Intensiva do Hospital da Criança Santo Antônio/Irmandade da Santa Casa de Misericórdia de Porto Alegre, principalmente aqueles fatores associados ao óbito. Métodos: Os pacientes foram alocados prospectiva e consecutivamente por um período de um ano (agosto de 2005 a julho de 2006). Agora, 15 anos após a seleção inicial, coletamos dados desses pacientes no banco de dados do Laboratório de Citogenética da Universidade Federal de Ciências da Saúde de Porto Alegre e nos prontuários do hospital. Resultados: Dos 96 pacientes, 11 faleceram e 85 permaneceram vivos até completar 20 anos. Quatro pacientes morreram na Unidade de Terapia Intensiva. A probabilidade de sobrevida até 365 dias de vida foi de 95,8%. A avaliação da sobrevida identificou que os óbitos ocorreram principalmente antes de os pacientes completarem mil dias de vida. Verificamos que a doença cardíaca complexa foi independentemente associada a um odds ratio de 5,19 (intervalo de confiança — IC95% 1,09-24,71; p=0,038) para morte. Conclusões: O conhecimento dos fatores que interferem no prognóstico pode ser fundamental no planejamento da prática assistencial, principalmente considerando-se que as cardiopatias congênitas são importante causa de mortalidade no primeiro ano de vida.

Risk factors and characteristics of the birth of patients with craniofacial microsomia, a case-control study.

BACKGROUND: Craniofacial microsomia (CM) is characterized by changes in the first and second branchial arches. It is a clinical condition whose etiology is still uncertain, but studies have shown that genetic, nutritional, and environmental factors can result in disorders of blastogenesis of the branchial arches. This study evaluates gestational aspects, focusing on possible risk factors associated with CM. METHODS: This is a case-control study conducted with patients monitored at a medical genetics service and compared to a control group of patients without evidence of malformations, born in a mother and child hospital, both located in Porto Alegre, Southern Brazil. Mothers' data were obtained using questionnaires and by reviewing medical records. The sample consisted of 43 patients with CM (cases) and 129 patients without evidence of malformations (controls), paired by sex, totaling three controls for each case. Data analysis was performed using the two-tailed Fisher's exact test, Pearson's chi-square test, and the t-test. RESULTS: We identified several factors associated with the development of CM, including the use of abortion methods by the mothers of these babies (p = .001), maternal diabetes (p = .009), advanced maternal age (p = .035), and a history of vaginal bleeding (p < .001). Furthermore, these patients exhibited a tendency to be born prematurely (p = .027), with low birth weight (p = .007), and lower Apgar scores (p = .003) when compared to healthy infants. Using a multivariate model, the use of abortion methods (p = .003) and vaginal bleeding (p = .032) remained independently associated with craniofacial microsomia. CONCLUSIONS: We have identified several risk factors for the development of CM, including a propensity for premature birth, low birth weight, and respiratory difficulties. Additionally, women of advanced maternal age and/or those who used abortion methods and/or have diabetes have a higher risk of giving birth to a baby with CM. This information can be valuable in clinical practice, especially for the prevention of future cases.

16p11.2 Microduplication Syndrome with Increased Fluid in the Cisterna: Coincidence or Phenotype Extension?

We report the first case of a child with 16p11.2 microduplication syndrome with increased fluid in the cisterna magna seen on magnetic resonance imaging (MRI). This finding may correspond to a Blake's Pouch Cyst (BPC) or a Mega Cisterna Magna (MCM), being impossible to differentiate through image examination. The molecular duplication was diagnosed using chromosomal microarray analysis with single nucleotide polymorphism (SNP). We review the clinical and neuroimaging features in published case reports in order to observe the findings described in the literature so far and present a skull three-dimensional model to contribute to a better understanding. Despite the variable expressivity of the syndrome being well known, there is no case described in the available literature that mentions the association of 16p11.2 microduplication and the presence of BPC or MCM seen in neuroimaging exams. This finding may represent an extension of the phenotype not yet reported or may present itself as a coincidence in a child with various malformations.

PDGFRA, KIT, and KDR Gene Amplification in Glioblastoma: Heterogeneity and Clinical Significance.

Glioblastoma (GBM) is the most frequent tumor of the central nervous system, and its heterogeneity is a challenge in treatment. This study examined tumoral heterogeneity involving PDGFRA, KIT, and KDR gene amplification (GA) in 4q12 and its association with clinical parameters. Specimens from 22 GBM cases with GA for the 4q12 amplicon detected by FISH were investigated for homogeneous or heterogeneous coamplification patterns, diffuse or focal distribution of cells harboring GA throughout tumor sections, and pattern of clustering of fluorescence signals. Sixteen cases had homogenously amplification for all three genes (45.5%), for PDGFRA and KDR (22.7%), or only for PDGFRA (4.6%); six cases had heterogeneous GA patterns, with subpopulations including GA for all three genes and for two genes - PDGFRA and KDR (13.6%), or GA for all three and for only one gene - PDGFRA (9.1%) or KIT (4.6%). In 6 tumors (27.3%), GA was observed in focal tumor areas, while in the remaining 16 tumors (72.7%) it was diffusely distributed throughout the pathological specimen. Amplification was universally expressed as double minutes and homogenously stained regions. Coamplification of all three genes PDGFRA, KIT, and KDR, age ≥ 60 years, and total tumor resection were statistically associated with poor prognosis. FISH proved effective for detailed interpretation of molecular heterogeneity. The study uncovered an even more diverse range of amplification patterns involving the 4q12 oncogenes in GBM than previously described, thus highlighting a complex tumoral heterogeneity to be considered when devising more effective therapies.

Fluorescence in situ hybridization (FISH) as an irreplaceable diagnostic tool for Williams-Beuren syndrome in developing countries: a literature review.

OBJECTIVE: The aim of this study was to sum up and characterize all Williams-Beuren syndrome cases diagnosed by fluorescence in situ hybridization (FISH) since its implementation, as well as to discuss FISH as a cost-effective methodology in developing countries. DATA SOURCE: From January 1986 to January 2022, articles were selected using the databases in PubMed (Medline) and SciELO. The following terms were used: Williams syndrome and In Situ Hybridization, Fluorescence. Inclusion criteria included Williams-Beuren syndrome cases diagnosed by FISH with a stratified phenotype of each patient. Only studies written in English, Spanish, and Portuguese were included. Studies with overlapping syndromes or genetic conditions were excluded. DATA SYNTHESIS: After screening, 64 articles were included. A total of 205 individuals with Williams-Beuren syndrome diagnosed by FISH were included and further analyzed. Cardiovascular malformations were the most frequent finding (85.4%). Supravalvular aortic stenosis (62.4%) and pulmonary stenosis (30.7%) were the main cardiac alterations described. CONCLUSIONS: Our literature review reinforces that cardiac features may be the key to early diagnosis in Williams-Beuren syndrome patients. In addition, FISH may be the best diagnostic tool for developing nations that have limited access to new technologic resources.

Características clínicas e fonoaudiológicas de neonatos hospitalizados em uma Unidade de Tratamento Intensivo neonatal com suspeita de doença genética / Clinical and speech-language pathology characteristics of neonates hospitalized in a neonatal Intensive Care Unit with suspected genetic disease / Características clínicas y de patología del habla y lenguaje de neonatos hospitalizados en una Unidad de Cuidados Intensivos neonatales con sospecha de enfermedad genética

Introdução: A prematuridade é um fator de risco para o crescimento e o desenvolvimento dos neonatos. Objetivo: Analisar as características clinicas e fonoaudiológicas de neonatos hospitalizados na unidade de tratamento intensivo (UTI) neonatal com suspeita de doença genética. Material e Método:Estudo transversal descritivo, conduzido em um hospital na região sul do Brasil com coleta de dados entre novembro de 2020 e setembro de 2021. Todos os neonatos que se encontravam internados na UTI, atendidos pelo Sistema Único de Saúde e que apresentavam suspeita de etiologias genéticas foram acompanhados pela equipe de Fonoaudiologia. Foram analisados todos os prontuários dos recém-nascidos com suspeita de alteração genética, extraindo-se os dados médicos e fonoaudiológicos. Resultados:A amostra foi constituída por 14 neonatos prematuros com média de idade gestacional de 36 semanas e 5 dias e uma média de tempo de nascimento, no momento da avaliação fonoaudiológica, de 14,6 dias de vida. No que se refere às comorbidades, 71,4% dos recém-nascidos apresentavam alguma malformação, sendo múltiplas na maior parte dos casos (64,29%). Todos os neonatos estavam fazendo uso de via enteral de alimentação durante a avaliação fonoaudiológica. Na avaliação de reflexos orais, observou-se que houve um predomínio de pacientes com reflexo de procura débil, sendo que a maior parte apresentava reflexo de sucção presente. Conclusões: Pode-se afirmar que, neste estudo, a amostra foi composta por pacientes principalmente prematuros que apresentavam malformações múltiplas e que todos faziam uso de via alternativa de alimentação sugerindo, assim, a necessidade de atendimento fonoaudiológico como parte da assistência multidisciplinar desses neonatos.

Introduction: Prematurity is a risk factor for the growth and development of neonates. Objective: To analyze clinical and speech therapy characteristics of neonates hospitalized in the neonatal intensive care unit with suspected genetic disease. Method: Descriptive cross-sectional study conducted in a hospital in southern Brazil with data collection between November 2020 and September 2021. All neonates who were hospitalized in the ICU attended by the public health system and who were suspected of having genetic etiologies were followed up by the Speech-Language Pathology team. All newborn`s medical records with suspected genetic alterations were analyzed and the medical and the speech-language pathology data were analyzed. Results: The sample consisted of 14 premature neonates with a mean gestational age of 36 weeks and 5 days and a mean time of birth, at the time of the speech-language pathology assessment, of 14.6 days of life. Regarding to comorbidities, 71.4% of newborns had some malformation, being multiple in most cases (64.29%). All neonates were using enteral feeding at the time of the speech-language evaluation. At the oral reflexes evaluation it was observed that there was a predominance of patients with a weak rooting reflex and most of them had a present sucking reflex. Conclusions: In this study the sample consisted of mainly premature patients who had multiple malformations and all of them used an alternative feeding route, thus suggesting the demand for speech therapy as part of the multidisciplinary care of these neonates.

Chromosomal abnormalities detected by karyotyping among patients with secondary amenorrhea: a retrospective study.

BACKGROUND: Chromosomal abnormalities (CAs) have been described in patients with secondary amenorrhea (SA). However, studies on this association are scarce. OBJECTIVES: To evaluate the frequency and types of CAs detected by karyotyping in patients with SA. DESIGN AND SETTING: This retrospective study was performed in a reference clinical genetic service in South Brazil. METHODS: Data were obtained from the medical records of patients with SA who were evaluated between 1975 and 2022. Fisher's bicaudate exact test and Student's t-test were used, and P < 0.05 was considered significant. RESULTS: Among 43 patients with SA, 14 (32.6%) had CAs, namely del (Xq) (n = 3), 45,X (n = 2), 46,X,r(X)/45,X (n = 2), 46,XX/45,X (n = 1), 46,X,i(q10)/45,X (n = 1), 47,XXX (n = 1), 46,XX/47,XXX (n = 1), 46,XX/47,XX,+mar (n = 1), 45,XX,trob(13;14)(q10;q10)/46,XXX,trob(13;14)(q10;q10) (n = 1), and 46,XX,t(2;21)(q23;q11.2) (n = 1). Additional findings were observed mostly among patients with CA compared with those without CA (P = 0.0021). No difference in the mean age was observed between the patients with SA with or without CAs (P = 0.268025). CONCLUSIONS: CAs are common among patients with SA, especially those with short stature and additional findings. They are predominantly structural, involve the X chromosome in a mosaic, and are compatible with the Turner syndrome. Patients with SA, even if isolated, may have CAs, particularly del (Xq) and triple X.

Congenital Heart Defects and 22q11.2 Deletion Syndrome: A 20-Year Update and New Insights to Aid Clinical Diagnosis.

Congenital heart defects (CHDs) are one of the most prevalent clinical features described in individuals diagnosed with 22q11.2 deletion syndrome (22q11.2DS). Therefore, cardiac malformations may be the main finding to refer for syndrome investigation, especially in individuals with a mild phenotype. Nowadays, different cytogenetic methodologies have emerged and are used routinely in research laboratories. Hence, choosing an efficient technology and providing an accurate interpretation of clinical findings is crucial for 22q11.2DS patient's diagnosis. This systematic review provides an update of the last 20 years of research on 22q11.2DS patients with CHD and the investigation process behind each diagnosis. A search was performed in PubMed, Embase, and LILACS using all entry terms to DiGeorge syndrome, CHDs, and cytogenetic analysis. After screening, 60 papers were eligible for review. We present a new insight of ventricular septal defect as a possible pivotal cardiac finding in individuals with 22q11.2DS. Also, we describe molecular technologies and cardiac evaluation as valuable tools in order to guide researchers in future investigations.

Achados audiológicos na síndrome de Rubinstein-Taybi: revisão sistemática / Audiological findings in Rubinstein-Taybi syndrome: literature review

Objetivo: Verificar os achados audiológicos em sujeitos portadores da Síndrome de Rubinstein-Taybi (SRT) através de uma busca sistemática na literatura. Métodos: Foram utilizados os descritores "Rubinstein Taybi Syndrome" AND "Hearing" nas principais bases de dados. O levantamento limitou-se a publicações realizadas até junho de 2020, sem limitação de idioma. Foram incluídos todos os estudos que envolvessem avaliações auditivas realizadas em sujeitos portadores da SRT. Foram excluídos da análise, estudos que envolvessem população não portadora de SRT, cartas ao editor e estudos nos quais não foram encontrados os artigos originais. Resultados: A pesquisa resultou na seleção de cinco artigos que evidenciaram que não há uma padronização nos testes audiológicos devido à heterogeneidade das características encontradas na SRT. A perda auditiva do tipo condutiva foi amplamente relatada, porém não foi possível verificar se há um perfil audiológico nesta população. Conclusão: Verificou-se que poucos estudos avaliaram a audição dos portadores de SRT. Além disso, foi possível observar que ainda não são padronizados os testes audiológicos. Recomenda-se que sejam realizados mais estudos com amostras maiores a fim de conhecer quais são as alterações audiológicas mais comuns de modo que se indique precocemente a intervenção terapêutica mais adequada.

RESUMO Objetivo: Caracterizar todos os casos de síndrome de Williams-Beuren (SWB) diagnosticados por hibridização in situ fluorescente (FISH) desde sua implementação, assim como discutir a relação custo-benefício da metodologia de FISH em países em desenvolvimento. Fontes de dados: Entre janeiro de 1986 e janeiro de 2022 foi realizada uma busca nas bases de dados PubMed (Medical Literature Analysis and Retrieval System Online — Medline) e Scientific Electronic Library Online (SciELO) usando os seguintes termos: síndrome de Williams e hibridização in situ fluorescente. O critério de inclusão utilizado foi conter a descrição detalhada de caso(s) de SWB por FISH. Apenas estudos escritos em inglês, espanhol e português foram incluídos. Trabalhos que apresentavam sobreposição de síndromes/condições genéticas foram excluídos. Síntese dos dados: Após os processos de inclusão, 64 artigos e 205 indivíduos com SWB diagnosticados por meio do método de FISH foram incluídos. O achado mais frequente entre os indivíduos foi a presença de algum tipo de malformação cardíaca (85,4%). A estenose aórtica supravalvar (62,4%) e a estenose pulmonar (30,7%) foram as alterações cardíacas mais descritas. A maioria dos estudos era proveniente dos continentes Europa, Ásia e América do Norte. Conclusões: A presente revisão de literatura reitera que as malformações cardíacas podem ser a chave para o diagnóstico precoce em pacientes com SWB. Ainda, a técnica de FISH parece ser a melhor ferramenta de diagnóstico para os países em desenvolvimento, cujo acesso às novas tecnologias ainda é escasso.

Trisomy 21 and Ebstein Anomaly: Diagnosis and Prognosis of a Rare Association.

Trisomy 21 is considered the most common chromosomal aneuploidy, and congenital heart disease (CHD) is highly prevalent and relevant to the morbidity and mortality of these patients. Ebstein anomaly (EA) is a rare CHD characterized by tricuspid valve dysplasia with inferior septal leaflet displacement. Herein, we described a patient with trisomy 21 who presented with EA and discuss the association between the two conditions based on a literature review. We conclude that the concomitant occurrence of both conditions is considered to be rare. These individuals are most frequently diagnosed during birth and childhood, and they usually have a good prognosis, as observed with our patient and is typical for EA patients in general. However, it is important to be aware that electrophysiologic anomalies may also be present.

Clinical and cytogenetic characteristics of patients diagnosed with Turner syndrome in a clinical genetics service: cross-sectional retrospective study.

BACKGROUND: Turner syndrome (TS) is a rare genetic disease. Understanding its clinical findings contributes to better management of clinical conditions. OBJECTIVE: To investigate the clinical and karyotypic characteristics of patients diagnosed with TS at two reference services for clinical genetics in southern Brazil. DESIGN AND SETTING: Retrospective cross-sectional study conducted in two clinical genetics services in Porto Alegre (RS), Brazil. METHODS: The sample consisted of 59 patients with TS diagnosed from 1993 to 2019. A review of their medical records was performed and a standard protocol was filled out. RESULTS: The average age of the patients at diagnosis was 15.9 years, and 40.7% were over 13 years old. The largest proportion of them (42.4%) had been referred from an endocrinology department and their constitution was 45,X (40.7%). The most common clinical findings were short stature (85.7%), hypoplastic/ hyperconvex nails (61.2%), low posterior hairline (52.1%) and cubitus valgus (45.8%). There was no difference regarding the presence of short stature (P = 0.5943), number of dysmorphia (P = 0.143), anatomical regions affected and malformations identified through imaging examinations (P = 1.0000), regarding the presence or absence of 45,X constitution. Only 6% of the patients had used growth hormone and 43%, estrogen. CONCLUSION: We found that, in general, patients with TS were being diagnosed late. This has important implications for their treatment. In addition, only a small proportion of the patients were undergoing further examination or evaluation, which appeared to be leading to underdiagnosis of many abnormalities.

Handling of antineoplastic drugs: a health concern among health care workers.

INTRODUCTION: Health care professionals are part of a group that is more exposed to a wide range of sources of risk that are very harmful to their own health. Antineoplastic drugs are widely used to treat many different types of cancer and are very aggressive to both patients and health care professionals. OBJECTIVES: To identify occupational risks and assess knowledge in health care professionals from Porto Alegre whose work involves handling antineoplastic drugs. METHODS: This was a prospective, descriptive, and cross-sectional study with qualitative and quantitative analyses. It was conducted in two stages. A questionnaire containing objective questions was administered in stage one. In stage two, observations were made during regular visits to the sites studied at different times, following a checklist based on the requirements of health regulation standards relating to handling of antineoplastic drugs. RESULTS: A total of 40 health care professionals took part in the study, 11 nurses, 14 pharmacists, and 15 nursing and/or pharmacy technicians. Twenty-seven of them had been involved in some type of accident during their professional practice. It was also observed that the institutions were making efforts to comply with legal requirements, since 32 reported that they took part in the Program for Medical Control of Occupational Health and 29 of the employees stated they had had some type of training in the antineoplastic area. CONCLUSIONS: Exposure to antineoplastic drugs through contact, aerosols, ingestion, and inhalation was detected. Additionally, ergonomic, physical, and biological risks were also present, since working with different pathological organisms and working processes impacts on these workers' health. Assessment of the health care professionals' knowledge identified a lack of knowledge and weaknesses with relation to handling this class of drugs.

Pseudohypoparathyroidism with Ectopic Calcification and 22q11 Deletion Syndrome: A Rare Case.

Ectopic calcification in soft tissue is associated with several disorders including pseudohypoparathyroidism (PHP), which is characterized by resistance or nonresponse to parathyroid hormone (PTH) function. Association between PHP and 22q11DS, also known as DiGeorge syndrome, is rare, especially in children. We describe a newborn girl diagnosed with 22q11DS, presenting ectopic calcifications in soft tissue and suspicion of PHP. PTH function showed values close to the upper limit of the reference value. Radiology showed bone callus in the right wrist. PHP can be a new clinical finding associated with 22q11DS. Parathyroid function investigation in individuals with 22q11DS, presenting bone dysmorphisms and/or calcium metabolism alterations, should be considered.

Unusual Characteristics and Variable Expressivity in a Brazilian Family with Cherubism.

Cherubism is a rare genetic condition characterized by a bone nonneoplastic disease. We aimed to report a 6-year-old girl with cherubism presenting similar cases in the maternal family. However, her mother and grandmother seemed to be asymptomatic. The patient had an enlarged and asymmetric jaw with multiple enlarged cervical lymph nodes that increased in size with time. Sanger sequencing revealed a heterozygous mutation in exon 9 of SH3BP2 not only in the patient but also in her mother. Thus, we observed a variable expression and a probably reduced penetrance within the family, as well as unusual characteristics of the patient (in this case, the asymmetrical involvement of the jaw).

Diagnósticos de enfermagem na síndrome de Turner / Nursing diagnoses in Turner syndrome

A síndrome de Turner é uma doença genética rara e possui repercussão importante na assistência em saúde destas pacientes. Apesar da ST não ser incomum, ainda existem lacunas na literatura acerca da assistência de enfermagem. O objetivo do trabalho foi inferir diagnósticos de enfermagem a partir das condições clínicas apresentadas pelas pacientes com síndrome de Turner (ST), conforme a taxonomia II NANDA-I. Trata-se de um estudo transversal e retrospectivo, de abordagem quantitativa. A amostra foi constituída por 59 pacientes com ST, diagnosticadas no período de 1993 a 2019. Os dados foram extraídos dos seus prontuários e submetidos à inferência diagnóstica pautados na taxonomia II NANDA-I. O julgamento clínico ocorreu com as principais dismorfias descritas entre as pacientes. No que tange aos resultados, a constituição cromossômica mais frequente foi a monossomia do cromossomo X (40,7%) e a média de idade do diagnóstico das pacientes foi de 15,9 anos (variou de 1 mês a 34 anos). As principais dismorfias descritas foram: baixa estatura, cúbito valgo, pectus excavatum e palato ogival. Os diagnósticos inferidos para a população estudada foram isolamento social, mobilidade física prejudicada, deglutição prejudicada, baixa autoestima situacional e padrão respiratório ineficaz. Concluiu-se que a proposição de diagnósticos de enfermagem possibilita qualificar a assistência destas pacientes, a partir de evidências no cuidado à pacientes com doenças raras.

Turner's syndrome (TS) is a rare genetic disease and has an important impact on the health care of these patients. Although TS is not uncommon, there are still gaps in the literature about nursing care. The objective of the study was to infer nursing diagnoses from the clinical conditions presented by patients with Turner syndrome, according to NANDA-I taxonomy II. This is a cross-sectional and retrospective study, with a quantitative approach. The sample consisted of 59 patients with TS, diagnosed from 1993 to 2019. The data were extracted from their medical records and submitted to diagnostic inference based on the NANDA-I taxonomy II. The clinical judgment occurred with the main dysmorphias described among the patients. Regarding the results, the most common chromosomal constitution was X chromosome monosomy (40.7%) and the mean age of the patients at diagnosis was 15.9 years (ranged from 1 month to 34 years). The main dysmorphias described were: short stature, ulna valgus, pectus excavatum, and ogival palate. The diagnoses inferred for the studied population were social isolation, impaired physical mobility, impaired swallowing, low situational self-esteem, and ineffective breathing patterns. It was concluded that the proposal of nursing diagnoses makes it possible improve the assistance of these patients, based on evidence in the care of patients with rare diseases.
