Homogenous access to fetal cardiac care in a heterogeneous state.

BACKGROUND: Timely prenatal diagnosis of CHD allows families to participate in complex decisions and plan for the care of their child. This study sought to investigate whether timing of initial fetal echocardiogram and the characteristics of fetal counselling were impacted by parental socio-economic factors. METHODS: Retrospective chart review of fetal cardiac patients from 1 January, 2017 to 31 December, 2018. We reviewed gestational age at first fetal echo, maternal age and ethnicity, zip code, rurality index, and hospital distance. Counselling was evaluated based on documentation regarding use of interpreter, time billed for counselling, and treatment option chosen. RESULTS: Total of 139 maternal-fetal dyads were included, and 29 dyads had single-ventricle heart disease. There was no difference in income, hospital distance or rurality index, and first fetal echo timing. There was no significant difference between maternal ethnicity and maternal age, gestational age at initial visit, or follow-up. Patients in rural areas had increased counselling time (p < .05). There was no difference between socio-economic factors and ultimate parental choices (termination, palliative delivery, or cardiac interventions). CONCLUSION: Oregon comprises a heterogeneous population from a large geographical catchment. While prenatal counselling and family decision-making are multifaceted, we demonstrated that dyads were referred from across the state and received care in a uniformly timely manner, and once at our centre received consistent counselling despite differences in parental socio-economic factors.

Do Standardized Scripts Improve Interpreter Use by Spanish-Speaking Patients?

Patients with limited English-proficiency (LEP) who need but do not receive interpreters have lower satisfaction and poorer understanding. A knowledge gap remains regarding the optimal way to offer interpreters. Using standardized scripts, we will determine whether the questions we use to offer interpreters increase utilization. Pilot prospective cohort study of postpartum mothers with LEP. Subjects were assigned one of three unique scripted question offering an interpreter. Data were analyzed using ANOVA, chi-square test, and Fisher's exact test. Fifty-five LEP patients were randomized into three study arms with similar sociodemographics. Overall interpreter use was 80% (44/55). There was a significant difference in interpreter utilization: 82.4%, 63.6%, 100%, respectively by arm (p = 0.015). Highest interpreter utilization occurred with "In what language do you prefer to receive your medical care?". There is opportunity for providers to refine the way they offer interpreters to optimize utilization.

Facial protection for healthcare workers during pandemics: a scoping review.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has led to personal protective equipment (PPE) shortages, requiring mask reuse or improvisation. We provide a review of medical-grade facial protection (surgical masks, N95 respirators and face shields) for healthcare workers, the safety and efficacy of decontamination methods, and the utility of alternative strategies in emergency shortages or resource-scarce settings. METHODS: We conducted a scoping review of PubMed and grey literature related to facial protection and potential adaptation strategies in the setting of PPE shortages (January 2000 to March 2020). Limitations included few COVID-19-specific studies and exclusion of non-English language articles. We conducted a narrative synthesis of the evidence based on relevant healthcare settings to increase practical utility in decision-making. RESULTS: We retrieved 5462 peer-reviewed articles and 41 grey literature records. In total, we included 67 records which met inclusion criteria. Compared with surgical masks, N95 respirators perform better in laboratory testing, may provide superior protection in inpatient settings and perform equivalently in outpatient settings. Surgical mask and N95 respirator conservation strategies include extended use, reuse or decontamination, but these strategies may result in inferior protection. Limited evidence suggests that reused and improvised masks should be used when medical-grade protection is unavailable. CONCLUSION: The COVID-19 pandemic has led to critical shortages of medical-grade PPE. Alternative forms of facial protection offer inferior protection. More robust evidence is required on different types of medical-grade facial protection. As research on COVID-19 advances, investigators should continue to examine the impact on alternatives of medical-grade facial protection.

Fibrodisplasia osificante progresiva. Reporte de un caso y revisión de la literatura

RESUMEN La fibrodisplasia osificante progresiva (FOP) es una enfermedad del tejido conectivo de etiología desconocida, de herencia autosómica dominante que se caracteriza por calcificaciones progresivas de las fascias, aponeurosis, ligamentos, tendones y tejido conectivo intersticial del músculo esquelético. Su prevalencia es de 1:2.000.000. Presenta desde el nacimiento morfología anormal del primer metatarsiano. Las osificaciones heterotópicas por lo común se hacen evidentes recién alrededor de los 5 años, posteriores a un trauma en los tejidos blandos. El compromiso funcional es progresivo y altamente incapacitante. Presentamos el caso de un niño de 6 años quien desde el año de edad inició las lesiones en las zonas de traumatismos, al comienzo acompañadas de dolor y signos inflamatorios que luego se petrificaban. Presentaba hállux valgus corto bilateral y se pudo corroborar la presencia de la misma malformación en un tío materno.

ABSTRACT Progressive ossifying fibrodysplasia (POF) is a connective tissue disease of unknown etiology, of autosomal dominant inheritance characterized by progressive calcifications of fasciae, aponeurosis, ligaments, tendons, and interstitial connective tissue of skeletal muscle. Its prevalence is 1: 2,000,000. Abnormal morphology of the first metatarsal is present at birth. Heterotopic ossifications usually become apparent only about 5 years after a soft tissue trauma. The functional compromise is progressive and highly disabling. We present the case of a 6-year-old boy who, beginning at one year of age, developed the lesiones in injured areas, with subsequent petrification, initially accompanied by pain and inflammatory signs. He presented bilateral short hallux valgus and we corroborated the presence of the same malformation in a maternal uncle.

Use of local anesthetic for the resolution of benign anorectal pathology in the Social Security Institute of Guatemala (IGSS) / Uso de anestésico local para resolução de patologia anorretal benigna no Instituto Guatemalteco de Seguridade Social

Abstract Introduction The use of regional anesthetic block has increased, along with the reduction of the use of spine anesthetic in this particular field of surgical activity. In the last decade ambulatory surgery and local anesthetic have lower surgical time, complications of the anesthetic itself, and hospital stay. Objective Presenting the results obteained with the use of local anesthesic and analgesic in the resolution of benign anorectal pathology. Methods A prospective, longitudinal, study, from January 2017 to December 2017, patients were classified according to surgical procedures performed using analogical visual scale to determine the pain tolerance, during the procedure, 24 h later and in the 5th post operative day. Results 253 procedures were performed with 116 local analgesia, 116 were male (45.86%) years 137 female (54%), Milligan-Morgan hemorroidectomy with Ligasure and fistulotomy were the most frequently performed procedures 32% each, followed by biopsy 16%, left lateral esfinterotomy 13% and cutaneous appendix 12%. Females presented better pain tolerance than males patients (92 vs. 81), 68% referred good tolerance through the procedure. Conclusions 68% of all the patients obtained good pain tolerance through anal anesthetic block, females manifested better pain tolerance than males, in non-complicated anorectal pathology local block ha shown to be safe and reproductible for the treatment of benign anorectal pathology in the Guatemalan Institute for Social Security.

Resumo Introdução O uso de bloqueio anestésico regional aumentou ao mesmo tempo em que diminuiu o uso do anestésico espinhal nesse campo específico da atividade cirúrgica. Na última década, a cirurgia ambulatorial e o anestésico local apresentaram um tempo cirúrgico menor, menos complicações associadas ao próprio anestésico e redução da permanência hospitalar. Objetivo Apresentar os resultados obtidos com o uso de anestésico local e analgésico na resolução da patologia anorretal benigna. Métodos Estudo prospectivo, longitudinal, realizado no período de janeiro a dezembro de 2017. Com o uso de uma escala visual analógica, os pacientes foram classificados para determinar a tolerância à dor durante o procedimento, 24 horas após a cirurgia e no quinto dia de pós-operatório. Resultados No total, 253 procedimentos foram realizados com 116 analgesias locais; 116 pacientes eram do sexo masculino (4586%) e 137 do sexo feminino (54%). A técnica de Milligan-Morgan para hemorroidectomia com ligadura e a fistulotomia foram os procedimentos realizados com mais frequência (32% cada), seguidos de biópsia (16%), esfincterotomia lateral esquerda (13%) e apêndice cutâneo (12%). As mulheres apresentaram melhor tolerância à dor que os homens (92 vs. 81), e 68% apresentaram boa tolerância durante o procedimento. Conclusões De todos os pacientes, 68% apresentaram boa tolerância à dor com o uso de bloqueio anestésico por via retal; as mulheres manifestaram melhor tolerância à dor que os homens. Na patologia anorretal não complicada, o bloqueio local mostrou ser seguro e reprodutível para o tratamento da patologia anorretal benigna no Instituto Guatemalteco de Seguridade Social.

Ceramic veneers on central incisors without finish line using bopt in a case with gingival asymmetry.

OBJECTIVES: This clinical case report describes the rehabilitation of central incisors with veneers in a patient with gingival asymmetry. The teeth were prepared without finish line, applying BOPT concepts to correct asymmetry, and obtained a harmoniously integrated restoration with optimal periodontal health. CLINICAL IMPLICATIONS: Biologically oriented preparation technique (vertical or "feather edge" preparation) was used to obtain gingival symmetry. Teeth were prepared without horizontal finish line to achieve correct emergence, soft tissue adaptation and stabilization, while maintaining biological space, both at the provisional restoration stage and later when definitive restorations were placed. To perform the technique correctly, it is essential to perform adequate periodontal diagnosis to verify the space available between the bone crest and the future margin of the restoration. CONCLUSIONS: It is possible to correct gingival asymmetry by performing dental preparation without finish line providing a correct periodontal analysis is first performed, which will contribute to successful soft tissue stabilization. CLINICAL SIGNIFICANCE: Beyond of all the prosthodontic preparation techniques, knowledge of B.O.P.T. (Biological Oriented Preparation Technique) allows us to achieve predictable and consistent results in terms of periodontal health and gingiva architecture surrounding ceramic veneers. Nevertheless long term studies are necessary to ensure the benefits of this techniques. Key words:Gingival margin, emergence profile, biologically oriented preparation technique.

Taquicàrdia ventricular idiopàtica infantil / Taquicardia ventricular idiopática infantil / Infantile idiopathic ventricular tachycardia

Introducció: Les arrítmies ventriculars en l'edat pediàtrica poden presentar-se des de formes asimptomàtiques amb extrasístoles ventriculars aïllades fins a formes amb taquicàrdia ventricular sostinguda amb insuficiència i aturada cardíaques. La taquicàrdia ventricular idiopàtica infantil és una de les entitats clíniques dins d'aquest grup, amb unes característiques clíniques i de pronòstic diferenciades, i amb una evolució generalment benigna. Observació clínica: Presentem dos casos clínics neonatals amb taquicàrdia ventricular idiopàtica infantil. Tots dos van debutar en forma de taquicàrdia ventricular ben tolerada hemodinàmicament, però donada la freqüència d'aparició dels episodis es va decidir iniciar tractament antiarrítmic amb propranolol i, posteriorment, flecaïnida. En tots dos casos, al cap de 24-48 hores d'introducció de la flecaïnida es va observar un canvi a ritme sinusal i desaparició dels episodis de taquicàrdia ventricular. En el seguiment posterior no van presentar nous episodis arrítmics. Comentaris: El reconeixement de les característiques clíniques i electrocardiogràfiques és essencial per fer un diagnòstic i un tractament correctes d'aquesta malaltia, així com per establir el diagnòstic diferencial amb altres taquicàrdies ventriculars que presenten un pronòstic pitjor

Introducción: Las arritmias ventriculares en la edad pediátrica pueden presentar desde formas asintomáticas clínicas con extrasístoles ventriculares aisladas hasta formas con taquicardia ventricular sostenida con insuficiencia cardíaca y paro cardíaco. La taquicardia ventricular idiopática infantil es una de las entidades clínicas dentro de este grupo, con unas características clínicas y de pronóstico diferenciadas y con una evolución generalmente benigna. Observación clínica: Presentamos dos casos clínicos neonatales con taquicardia ventricular idiopática infantil. Ambos debutaron en forma de taquicardia ventricular bien tolerada hemodinámicamente, pero dada la frecuencia de aparición de los episodios se decidió iniciar tratamiento antiarrítmico con propranolol y posteriormente flecainida. En ambos casos, a las 24-48 horas de introducción de la flecainida se observa paso a ritmo sinusal y desaparición de los episodios de taquicardia ventricular. En el seguimiento posterior no se observa reaparición de episodios arrítmicos. Comentarios: El reconocimiento de las características clínicas y electrocardiográficas es esencial para la correcta valoración y tratamiento de esta enfermedad, así como para el diagnóstico diferencial con otras taquicardias ventriculares que presentan un peor pronóstico

Introduction: Ventricular arrhythmias in children can present in a wide range of clinical manifestations, varying from patients that are completely asymptomatic with isolated ventricular ectopic beats to more severe forms with sustained ventricular tachycardia, heart failure and cardiac arrest. Infantile idiopathic ventricular tachycardia is one of the clinical entities within this group with different clinical characteristics and prognosis and with a generally benign evolution. Clinical observation: We present two cases of neonatal presentation of infantile idiopathic ventricular tachycardia. Both cases presented in the form of hemodynamically tolerated ventricular tachycardia, but given the frequency of occurrence of the episodes a decision was made to initiate antiarrhythmic treatment with propranolol and subsequently flecainide. In both cases, sinus rhythm and disappearance of episodes of ventricular tachycardia were documented at 24-48 hours of introduction of flecainide. Both patients had a complete resolution, with no recurrence of arrhythmic episodes on subsequent follow-up. Comments: The prompt recognition of the clinical and electrocardiographic characteristics is essential for the correct assessment and treatment of this disease, as well as for the differential diagnosis with other ventricular tachycardias that carry a worse prognosis

Todos los pacientes tenían coriorretinitis. Y en el 7% se acompañaron de uveítis. La afectación fue bilateral en 52.8%. Las lesiones eran inactivas en 87,5 con localización central. Presentaron complicaciones en el 58,3% de los pacientes: estrabismo en 76% y en 24 % desprendimiento de retina. Conclusión: La frecuencia de TO fue del 0,8%. La mayoría de los pacientes tenían más de 2 años de edad y el 19% tenía toxoplasmosis congénita. Todos tuvieron corioretinitis, con compromiso bilateral y localización central más frecuentemente. Hubo predominio de lesiones inactivas tanto en la toxoplasmosis congénita como en la adquirida. Las complicaciones fueron estrabismo y desprendimiento de retina.

Introduction: Toxoplasmosis frequently affects the posterior chamber of the eye and can cause vision loss. Objective: To describe the frequency and clinical characteristics of ocular toxoplasmosis in a pediatric ophthalmology clinic. Materials and Methods: this was an observational, descriptive and retrospective study. We reviewed the clinical histories of patients from 0 to 18 years of age, with ocular toxoplasmosis, treated in the pediatric ophthalmology clinic, from January 2011 to May 2014. Variables were age, sex, form of toxoplasmosis, ocular lesion type, lesion location, unilateral or bilateral involvement, and ocular complications. The data was analyzed with SPSSv21 using descriptive and inferential statistics. Informed consent was not necessary because it was a retrospective study. Results: 72 patients were included. The median age was 48 months; 6.9% were neonates, 52.8% were female. 80.5% had acquired toxoplasmosis and 19.4% congenital. All the patients had chorioretinitis and 7% also had uveitis. Bilateral affectation was present in 52.8%. The lesions were inactive at 87.5% with central location. Complications were present in 58.3% of patients: strabismus in 76% and 24% had retinal detachment. Conclusion: The frequency of OT was 0.8%. The majority of the patients were over 2 years of age and 19% had congenital toxoplasmosis. All had chorioretinitis, with bilateral involvement and central location present more frequently. There was a predominance of inactive lesions in both congenital and acquired toxoplasmosis. The most common complications were strabismus and retinal detachment.

Dengue y Bradicardia: caracterización clínica y evolución

Introducción: Las alteraciones de la conducción cardiaca y bradicardia, están descriptos en el Dengue, aunque su fisiopatología no es del todo clara. Objetivo: Describir las características clínicas y evolución de los pacientes con dengue y bradicardia. Metodología: estudio observacional, descriptivo, longitudinalde seguimiento de una cohorte. Fueron incluidos pacientes de 1 mes a 18 años ingresados en el Servicio de Urgencias del Hospital General Pediátrico Niños de Acosta Ñu, con diagnóstico de dengue, que presentaron bradicardia y que hayan tenido seguimiento hasta la desaparición del síntoma. Variables edad, sexo, clasificación del dengue, resultado del electrocardiograma (ECG), radiografía de tórax, inicio de bradicardia, frecuencia cardiaca al egreso, duración de la bradicardia en el seguimiento y días de hospitalización. Los datos fueron analizados en SPSSv 21, utilizando la estadística descriptiva. El protocolo fue aprobado por el Comité de ética. Resultados: En el periodo de estudio se hospitalizaron 310 pacientes con Dengue. El 6,4% (20/310) presentó bradicardia. La edad media fue de 12,7±2,8 años, con predominio del sexo masculino. Algunos pacientes ya tenían bradicardia en el momento del ingreso (9/20), mientras que otros lo presentaron en el curso de la hospitalización (11/20). Hubo un caso de bloqueo AV y los demás presentaron bradicardia sinusal (19/29). La bradicardia persistió al alta en la mayoría de los pacientes (18/20) y se resolvió durante la primera semana de seguimiento. El promedio de días de hospitalización fue 7,1±1,9. Conclusión: La frecuencia de bradicardia fue del 6,4%. La mayoría de los pacientes tenía el diagnóstico de Dengue Grave. Un alto porcentaje continuaba con bradicardia al momento del alta sin manifestaciones clínicas de dengue. En la mayoría de los pacientes se presentó durante la hospitalización y se normalizó durante el seguimiento al alta.

Introduction: Alterations in cardiac conduction and bradycardia are described in Dengue, although its pathophysiology is not entirely clear. Objective: To describe the clinical characteristics and course of patients with dengue and bradycardia. Methodology: This was an observational, descriptive and longitudinal cohort study. We enrolled patients from 1 month to 18 years of age who were admitted to the Emergency Department of the Acosta Ñu Children's General Hospital with a diagnosis of dengue, who presented bradycardia and who had follow-up until the disappearance of the symptom. The variables were age, sex, dengue classification, electrocardiogram (ECG) results, chest x-ray, onset of bradycardia, heart rate at discharge, duration of bradycardia during follow-up and days of hospitalization. Data were analyzed in SPSSv 21, using descriptive statistics. The protocol was approved by the Hospital Ethics Committee. Results: During the study period, 310 patients with Dengue were hospitalized. 6.4% (20/310) had bradycardia. The average age was 12.7 ± 2.8 years, with a predominance of males. Some patients already had bradycardia at the time of admission (9/20), while others developed it during hospitalization (11/20). There was one case of AV block and the others presented sinus bradycardia (19/29). Bradycardia persisted at discharge in most patients (18/20) and resolved during the first week of follow-up. The average number of hospitalization days was 7.1 ± 1.9. Conclusions: The frequency of bradycardia was 6.4%. The majority of patients had a diagnosis of severe dengue. A high percentage of patients continued to have bradycardia at discharge with no other clinical manifestations of dengue. In the majority of patients, bradycardia presented during hospitalization and normalized at their discharge follow-up.

SNAP II and SNAPPE II as Predictors of Neonatal Mortality in a Pediatric Intensive Care Unit: Does Postnatal Age Play a Role?

Introduction. In developing countries, a lack of decentralization of perinatal care leads to many high-risk births occurring in facilities that do not have NICU, leading to admission to a PICU. Objective. To assess SNAP II and SNAPPE II as predictors of neonatal death in the PICU. Methodology. A prospective study of newborns divided into 3 groups according to postnatal age: Group 1 (G1), of 0 to 6 days; Group 2 (G2) of 7 to 14 days; and Group 3 (G3), of 15 to 28 days. Variables analyzed were SNAP II, SNAPPE II, perinatal data, and known risk factors for death. The Hosmer-Lemeshow test and the receiver operating characteristics (ROC) curve were used with SPSS 17.0 for statistical analysis. An Alpha error <5% was considered significant. Results. We analyzed 290 newborns, including 192 from G1, 41 from G2, and 57 from G3. Mortality was similar in all 3 groups. Median SNAP II was higher in newborns that died in all 3 groups (P < 0.05). The area under the ROC curve for SNAP II for G1 was 0.78 (CI 95% 0.70-0.86), for G2 0.66 (CI 95% 0.37-0.94), and for G3 0.74 (CI 95% 0.53-0.93). The area under the ROC curve for SNAPPE II for G1 was 0.76 (CI 95% 0.67-0.85), for G2 0.60 (CI 95% 0.30-0.90), and for G3 0.74 (CI 95% 0.52-0.95). Conclusions. SNAP II and SNAPPE II showed moderate discrimination in predicting mortality. The results are not strong enough to establish the correlation between the score and the risk of mortality.
