RWMAs in critically ill patients with non-obstructed coronary arteries

Introduction

Left ventricular (LV) dysfunction is estimated to occur in 10%–25% of the general intensive care unit (ICU) population and is frequently seen as regional wall motion abnormalities (RWMAs). Although RWMA is mostly attributed to myocardial ischemia or infarction, some studies have suggested that nonischemic RWMA might also be prevalent. We sought to establish that RWMA can be seen in critically ill patients with normal coronary arteries and to explore reasons for RWMA in this population.

Methods

In this retrospective study, data from the hospital angiography register and the ICU register were collated between 2012 and 2019. Patients were identified who underwent angiography in conjunction with their ICU stay and had RWMA on echocardiography. Patients were divided into either those with non-obstructed or those with obstructed coronary arteries. Cardiac magnetic resonance imaging (cMRI) examinations were reviewed if they had been performed on patients with non-obstructed coronaries.

Results

We identified 53 patients with RWMA and non-obstructed coronary arteries and 204 patients with RWMA and obstructed coronary arteries. Patients with non-obstructed coronary arteries were more often female, younger, and had fewer cardiovascular risk factors. They less commonly had ST elevation, but more frequently had T-wave inversion or serious arrhythmias. Troponin levels were higher in patients with obstructed coronary arteries, but NT-proBNP was similar between the groups. There were no differences in risk-adjusted 90-day mortality between patients with non-obstructed versus obstructed coronary arteries (OR 1.21, [95% CI 0.56–2.64], p = .628). In those with non-obstructed coronary arteries, follow-up echocardiography was available for 38 patients, of whom 30 showed normalization of cardiac function. Of the 14 patients with non-obstructed coronary arteries on whom cMRI was performed, 7 had a tentative diagnosis of Takotsubo syndrome or myocardial stunning; 4 had a myocardial infarction (preexisting in 3 cases); 1 patient had acute myocarditis; 1 patient had post-myocarditis; and 1 patient was diagnosed with dilated cardiomyopathy.

Conclusion

RWMA can be seen to occur in critically ill patients in the absence of coronary artery obstruction. Several conditions can cause regional hypokinesia, and cMRI is useful to evaluate the underlying etiology.     

Talon cusp in the temporary dentition of a patient with Kabuki syndrome: Case report with a two‐year follow‐up

The presence of dental abnormalities in the same individual may be related to syndromic cases and occur through associated systemic changes. Kabuki syndrome presents well‐defined systemic changes, but its clinical characteristics related to the oral cavity have not been fully explained. This study aimed to report the dental changes in a child diagnosed with Kabuki syndrome. A male brown patient aged 2 years and 7 months, accompanied by his mother to the dental visit, they main complaint was the presented of an additional tooth behind upper right central incisor. Anamnesis, intra‐ and extraoral examinations, and dental X‐rays were performed, revealing a talon cusp. Considering the dental clinical findings, the patient was referred to a medical geneticist who additionally requested cardiological and genetic examinations, which established the Kabuki syndrome. The caregivers were advised that the talon cusp would not cause any injury to the natural exfoliation of the tooth and that oral hygiene should be performed carefully. Abnormalities in the oral cavity and developmental delay may be associated with a potential undiagnosed syndrome. The medical evaluation becomes decisive for investigation, diagnosis, and final conduct of the case.     

儿童尿路感染的临床分析与治疗

目的 分析我院147例泌尿系感染住院患儿的临床及治疗情况,并结合国内外新的研究进展,为临床诊治提供参考依据。方法 应用描述性方法对我院2016年5月至2020年5月住院的147例泌尿系感染病例进行回顾性分析。结果 147例患儿中,男性88例(59.86%)。婴儿期人数最多,共63例(42.86%)。尿培养中以屎肠球菌及大肠埃希菌多见。治疗上有136例(92.52%)选用头孢菌素类抗生素,其中三代头孢有132例(89.80%);45例行排泄性膀胱输尿管造影的患儿中有22例(48.89%)存在膀胱输尿管返流。结论 泌尿系感染是儿童的常见病,由于它与泌尿系畸形特别是膀胱输尿管返流密切相关,易导致感染反复,因此早期诊治并寻找其潜在的畸形,可预防复发,改善预后。     

Parenchymal calcification is associated with the neurological prognosis in patients with congenital rubella syndrome

Congenital rubella syndrome (CRS) results from maternal rubella virus infection in early pregnancy. Abnormal neuroimaging findings have been analyzed in a small number of CRS patients in the past; however, their clinical significance has been poorly addressed. Therefore, we have investigated the neuroimaging findings of 31 patients with CRS from previous studies. The most common finding was parenchymal calcification, which was observed in 18 of 31 patients (58.1%). A multivariable logistic regression model showed that it was associated with psychomotor or mental retardation (p = 0.018), suggesting that parenchymal calcification in CRS could be a prognostic factor.     

Neuroblastoma: a master of disguise and a challenge to cure

Neuroblastoma is one of the commonest childhood cancers and typically affects very young children. It is characterized by a very broad spectrum of clinical presentation and outcome, driven by the biology of the tumour. This ranges from ‘low risk’ tumours, most commonly found in infants, which may spontaneously regress and have an excellent prognosis with minimal or no treatment, to ‘high risk’ disease, which carries a poor prognosis despite intensive multi-modal treatment. Although particular presentations may be associated with favourable or unfavourable outcome, the clinical features may mask the underlying biology of the tumour and a full assessment of the clinical and biological features is required to determine appropriate treatment. The International Neuroblastoma Risk Group classification, based on the age of the patient and the stage, grade and genetics of the tumour, is used to stratify treatment according to risk factors. This review provides an overview of current neuroblastoma management, focusing on how classification is applied in practice, and how this is used to determine individual patient treatment. The challenges that remain in treating patients with high-risk disease are discussed.     

Menstrual Dysfunction and Treatment Among Adolescents With Congenital Heart Disease

Study ObjectiveThis study describes menstrual dysfunction and treatment among adolescent and young adult (AYA) females with congenital heart disease (CHD).DesignData collected from a 1-time survey completed by AYA females (and mothers if AYA unable).SettingParticipants were recruited from pediatric cardiology clinics.ParticipantsFemale AYA with CHD, aged 14-21 years (N = 114).InterventionsNone.Main Outcome MeasuresThe questionnaire assessed sexual and reproductive health (SRH) concerns, behaviors, and management. Outcome measures were self-reported menstrual complaints, use of over-the-counter (OTC) pain relief medications for dysmenorrhea, reported visits with a clinician for a menstrual problem, and reported use of hormones for menstrual problems or birth control.ResultsMean age was 17.0 years (SD = 2.2). The majority of participants (83%) reported 1 or more menstrual complaints (67.5% cramping, 42.1% irregular menses, 46.5% heavy periods), and 88% reported any history of taking OTC medications for pain relief. Increased menstrual complaints were not associated with level of cardiac complexity, reported transplantation, or reported use of hormonal contraception. However, 32% of participants reported use of hormonal contraception for menstrual dysfunction. Combined oral contraceptive pills (COCs) were the most common; 2 of these women carried contraindications to estrogen.ConclusionsA large majority of AYA females with CHD reported menstrual dysfunction. Use of OTC medication for menstrual pain and inappropriate use of estrogen creates concerns that menstrual disorders may be unaddressed or addressed inappropriately. Thus, gynecological needs of adolescents with CHD may need to be specifically targeted by providers who feel comfortable with this population and their complex needs.
