Pregnancy outcomes in Portuguese women with multiple sclerosis: The PREGNIMS study
Full text linkINTRODUCTION:
Several questions about pregnancy in women with multiple sclerosis (MS) have been discussed, but clarification is still needed in some very practical issues. Portuguese data on this subject remain scattered and need to be analyzed in order to standardize clinical practice.
OBJECTIVE:
This study aimed to describe and analyze the impact of MS on pregnancy and perinatal health of children born to Portuguese mothers with the disease.
MATERIAL AND METHODS:
This is a multicenter, retrospective study of a cohort of Portuguese women with MS who were pregnant and who gave birth between 01/01/2011 and 31/12/2015. Demographic and clinical data related to maternal disease, pregnancy progression and events, childbirth and newborn health were collected.
RESULTS:
Ninety-seven women were recruited and 90 live births were evaluated. The mean maternal age at conception was 32.5 years, and 63.9% had no relapses in the previous year (98.0% had a relapsing-remitting MS and the EDSS score was ≤ 3 in 92.8% of the cases). Only 50.5% of the women had a preconception specific evaluation and 60 children were exposed to immunomodulatory therapies during pregnancy. Nineteen women had relapses during pregnancy. Childbirth was induced in 22.7% of the cases, and the caesarean section rate was 34%. Children exposed to immunomodulatory drugs during pregnancy had a lower birth length (p = 0.014), and there was also a trend toward lower birth weight (p = 0.054) in these newborns. Pre-conception EDSS score negatively correlated with the duration of pregnancy (r = -0.22; p = 0.029), weight (r = -0.23; p = 0.031) and cephalic perimeter at birth (r = -0.24; p = 0.033). There was no relationship between the occurrence of relapses or progression in EDSS score during pregnancy with any variables related to the newborn.
CONCLUSIONS:
In our cohort, it has been confirmed that MS has no negative effect on pregnancy or on children's perinatal health. However, the use of immunomodulatory drugs may have some impact on newborns' somatometric features.info:eu-repo/semantics/publishedVersio
Should tumbling E go out of date in amblyopia screening? Evidence from a population-based sample normative in children aged 3-4 years
Full text linkAIMS:
To determine a normative of tumbling E optotype and its feasibility for visual acuity (VA) assessment in children aged 3-4 years.
METHODS:
A cross-sectional study of 1756 children who were invited to participate in a comprehensive non-invasive eye exam. Uncorrected monocular VA with crowded tumbling E with a comprehensive ophthalmological examination were assessed. Testability rates of the whole population and VA of the healthy children for different age subgroups, gender, school type and the order of testing in which the ophthalmological examination was performed were evaluated.
RESULTS:
The overall testability rate was 95% (92% and 98% for children aged 3 and 4 years, respectively). The mean VA of the first-day assessment (first-VA) and best-VA over 2 days' assessments was 0.14 logMAR (95% CI 0.14 to 0.15) (decimal=0.72, 95% CI 0.71 to 0.73) and 0.13 logMAR (95% CI 0.13 to 0.14) (decimal=0.74, 95% CI 0.73 to 0.74). Analysis with age showed differences between groups in first-VA (F(3,1146)=10.0; p<0.001; η2=0.026) and best-VA (F(3,1155)=8.8; p<0.001; η2=0.022). Our normative was very highly correlated with previous reported HOTV-Amblyopia-Treatment-Study (HOTV-ATS) (first-VA, r=0.97; best-VA, r=0.99), with 0.8 to 0.7 lines consistent overestimation for HOTV-ATS as described in literature. Overall false-positive referral was 1.3%, being specially low regarding anisometropias of ≥2 logMAR lines (0.17%). Interocular difference ≥1 line VA logMAR was not associated with age (p=0.195).
CONCLUSIONS:
This is the first normative for European Caucasian children with single crowded tumbling E in healthy eyes and the largest study comparing 3 and 4 years old testability. Testability rates are higher than found in literature with other optotypes, especially in children aged 3 years, where we found 5%-11% better testability rates.info:eu-repo/semantics/publishedVersio
Generation of an integration-free induced pluripotent stem cell line (CSC-43) from a patient with sporadic Parkinson's disease
Full text linkAn induced pluripotent stem cell (iPSC) line was generated from a 36-year-old patient with sporadic Parkinson's disease (PD). Skin fibroblasts were reprogrammed using the non-integrating Sendai virus technology to deliver OCT3/4, SOX2, c-MYC and KLF4 factors. The generated cell line (CSC-43) exhibits expression of common pluripotency markers, in vitro differentiation into three germ layers and normal karyotype. This iPSC line can be used to study the mechanisms underlying the development of PD.info:eu-repo/semantics/publishedVersio
Tartamudez neurógena: revisión de la bibliografía
Full text linkINTRODUCTION:
Neurogenic stuttering is a disorder of neurologic origin in the rhythm of speech during which the patient knows exactly what he wants to say but is unable to because of an involuntary prolongation, cessation or repetition of a sound.
AIM:
To assemble new insights regarding the epidemiology, pathophysiology, diagnosis, evaluation and treatment of neurogenic stuttering.
DEVELOPMENT:
A review of all PubMed and Scopus published articles between January 2000 and September 2016 was performed. Thirty-three publications were analyzed. Neurogenic stuttering is a rare entity whose epidemiological incidence is yet not fully established. It is correlated with several neurological diseases and with several possible localizations within the nervous system. Notwithstanding the recent advances in the understanding of the underlying mechanism, it is not yet possible to establish a single pathophysiological mechanism of neurogenic stuttering. The differential diagnosis is complex and requires the detailed knowledge of other language disorders. The treatment is currently based on specific speech language therapy strategies.
CONCLUSION:
Neurogenic stuttering is a complex disorder which is not fully understood. Additional studies might help to better explain the underlying pathophysiological mechanism and to open doors to novel therapeutic methods.info:eu-repo/semantics/publishedVersio
Experiences During a Psychoeducational Intervention Program Run in a Pediatric Ward: A Qualitative Study
Full text linkHospitalization, despite its duration, is likely to result in emotional, social, and academic costs to school-age children and adolescents. Developing adequate psychoeducational activities and assuring inpatients' own class teachers' collaboration, allows for the enhancement of their personal and emotional competences and the maintenance of a connection with school and academic life. These educational programs have been mainly designed for patients with long stays and/or chronic conditions, in the format of Hospital Schools, and typically in pediatric Hospitals. However, the negative effects of hospitalization can be felt in internments of any duration, and children hospitalized in smaller regional hospitals should have access to actions to maintain the connection with their daily life. Thus, this investigation aims to present a psychoeducational intervention program theoretically grounded within the self-regulated learning (SRL) framework, implemented along 1 year in a pediatric ward of a regional hospital to all its school-aged inpatients, regardless of the duration of their stay. The program counts with two facets: the psychoeducational accompaniment and the linkage to school. All the 798 school-aged inpatients (M
age
= 11.7; SD
age
= 3.71; Mhospital stay = 4 days) participated in pedagogical, leisure nature, and SRL activities designed to train transversal skills (e.g., goal-setting). Moreover, inpatients completed assigned study tasks resulting from the linkage between the students' own class teachers and the hospital teacher. The experiences reported by parents/caregivers and class teachers of the inpatients enrolling in the intervention allowed the researchers to reflect on the potential advantages of implementing a psychoeducational intervention to hospitalized children and adolescents that is: individually tailored, focused on leisure playful theoretically grounded activities that allow learning to naturally occur, and designed to facilitate school re-entry after hospital discharge. Parents/caregivers highlighted that the program helped in the preparation for surgery and facilitated the hospitalization process, aided in the distraction from the health condition, promoted SRL competences, and facilitated the communication and linkage with school life. Class teachers emphasized the relevance of the program, particularly in the liaison between hospital and school, in the academic and psycho-emotional and leisure-educational support provided, and in smoothing the school re-entry.info:eu-repo/semantics/publishedVersio
Abernethy malformation: beware in cases of unexplained hepatic encephalopathy in adults-case report and review of the relevant literature
Full text linkThe Abernethy malformation consists of a congenital extrahepatic portosystemic shunt and is believed to be extremely rare in humans. The potential implications of abnormal portovenous shunting and decreased hepatic portal flow are numerous and potentially serious. Although congenital extrahepatic portosystemic shunts are increasingly suspected and diagnosed in specialized centres, much of their clinical presentation and natural history is not fully understood. Symptoms of portosystemic shunt are mainly caused by increased levels of ammonia, which lead to signs of encephalopathy. Therapeutic options depend on the type of shunt and its clinical course, so the classification of the congenital portosystemic shunt is a key finding in these patients.info:eu-repo/semantics/publishedVersio
Late presentation of vesicoureteral reflux: An unusual cause of pyelonephritis in adults
No full textINTRODUCTION:
Vesicoureteral reflux (VUR) corresponds to the reflux of urine from the bladder into the upper urinary system. It can be a congenital or an acquired anomaly and although its incidence is high in children it is uncommon in the adult life. One of its presentations in the adult population is the presence of recurrent Pyelonephritis.
CASE PRESENTATION:
Here we report a case of an adult patient with repetitive uncomplicated pyelonephritis caused by VUR. VUR was successfully managed endoscopically with subureteral injection of a bulking agent. A literature review of adult presenting VUR was performed.
DISCUSSION:
The first presentation of VUR in the adult life is rare. One of the most typical presentation is the presence of recurrent uncomplicated Pyelonephritis. Although no guidelines exists to study the presence of VUR in adult patients with Pyelonephritis, in the presence of several recurrent episodes of Pyelonephritis we should think in VUR as a possible cause. Even in adults, endoscopic management of VUR is an effective treatment with low morbidity.
CONCLUSION:
VUR can first present in the adult life, with recurrent episodes of UTI. The diagnosis is a suspicious one and is confirmed by VUCG. VUR in adults can be effectively managed with endoscopic injection of bulking agents.info:eu-repo/semantics/publishedVersio
Pseudomyogenic hemangioendothelioma: a little-known tumor
Full text linkPseudomyogenic hemangioendothelioma (PHE) is a rare indolent vascular tumor that typically has a multifocal presentation and involves multiple tissue planes. This report describes a 34-year-old man with multiple infiltrated brown papules and plaques on his left leg that had evolved for 6 months. The skin biopsy revealed a dermal and subcutaneous neoplasm composed of fascicles of spindle cells with atypia and epithelioid cells with prominent nucleoli and abundant eosinophilic cytoplasm. There was no evidence of necrosis, and the mitotic rate was low. There was strong reactivity with cytokeratin AE1/AE3, ERG, and FLI1, multifocal reactivity with smooth muscle actin, and focal reactivity with CD31. There was no expression of keratin MNF116, CAM5.2, CD34, CAMTA1, S100-protein, epithelial membrane antigen, melan-A, HMB-45, factor XIIIa, HHV8, or CD10. The nuclei of neoplastic cells showed intact expression of INI1. The clinical, histological, and immunophenotypical aspects were consistent with a diagnosis of PHE. A lower limb CT scan showed lesions in the skin, muscle, and bone planes. The patient was sent to an oncology center, where he maintains regular clinical and imagiological follow-up.info:eu-repo/semantics/publishedVersio
