RESUMO

Pantothenate kinase-associated neurodegeneration (PKAN, OMIM: 234200) results from biallelic pathogenic variants in PANK2 which encodes pantothenate kinase 2, a crucial mitochondrial enzyme involved in coenzyme A biosynthesis. Pantothenate kinase-associated neurodegeneration patients typically exhibit the distinctive "eye of the tiger" sign on brain magnetic resonance imaging in the globus pallidus, along with psychiatric symptoms, extrapyramidal movements such as parkinsonism and dystonia, eventual speech and gait impairments, and the presence of dysphagia. An 11-year-old girl, with fifth-degree consanguinity, demonstrated typical psychomotor development and growth until the age of 5, when she began experiencing psychiatric symptoms. At the age of 9, she developed hand tremors, progressing to generalized muscular dystonia. By age 10, she exhibited gait and speech impairment. Physical examination revealed extensive generalized dystonia, hand tremors, speech impairment, dysphagia, inability to walk, and heightened osteotendinous reflexes. Metabolic analysis identified dyslipidemia with partial response to statin treatment and normocalcemic hypercalciuria. Exome sequencing revealed a novel likely pathogenic variant in PANK2 (NM_001386393.1:c.526C > G) in a homozygotic state. Pantothenate kinase-associated neurodegeneration typically manifests with generalized dystonia and psychiatric symptoms. Here, we present a Pantothenate kinase-associated neurodegeneration patient with dyslipidemia and hypercalciuria as potentially previously undescribed metabolic phenotype.

RESUMO

STUDY OBJECTIVE: In girls born with an anorectal malformation (ARM), anatomical gynecological anomalies (GA) may be present and might need treatment. Therefore, the aim of this study was to provide an overview of GA in girls born with ARM in our cohort. Additionally, diagnostic timing and methods for GA were assessed. METHODS: A retrospective mono-center study was performed from January 2000 to December 2022. All patients assigned female at birth were eligible for inclusion. GA were classified according to ESHRE/ESGE classification. Outcomes were the number of girls with GA with subsequent screening methods, factors associated with GA, and GA requiring treatment. Uni- and multivariable logistic regression analyses were performed to identify the association between baseline characteristics and the presence of GA. RESULTS: In total, 128 girls were included, of whom 30 (24.1%) had additional GA, with vaginal anomalies being present most often (n = 17). Fifty-six patients (43.8%) underwent full screening, and this number improved over time (37.7% before 2018 vs 72.7% after 2018; P = .003). Thirteen of 30 patients (43.3%) required surgical treatment for their GA, without the occurrence of postoperative complications. CONCLUSION: Additional GA were present in almost a quarter of the girls born with an ARM, with vaginal anomalies most often identified. Despite GA being most often found in patients with cloacal malformations, these anomalies were also identified in patients with other ARM types. Surgical treatment was required in almost half of the girls with GA. Therefore, this study emphasizes the importance of screening for GA in patients with an ARM, regardless of the ARM type.

RESUMO

PURPOSE: First, to assess the number of patients with anorectal malformations (ARM) in whom additional urological and/or gynecological anomalies were identified through routine screening with cysto- or vaginoscopy prior to reconstructive surgery. Second, to assess potential procedure-related complications. METHODS: Retrospective mono-center cohort study, including all ARM patients born between January 2019 and December 2022. Routine screening consisted of cystoscopy for male patients, with the addition of vaginoscopy for female patients. Chi-square was used to compare the screening percentages over time. RESULTS: In total, 38 patients were included, of whom 27 (71.1%) underwent cystoscopy ± vaginoscopy, without the occurrence of complications. Nine of 13 females (69.2%) underwent cysto- and vaginoscopy and 18 of 25 males (72.0%) underwent a cystoscopy. The percentage of patients that underwent these procedures improved over the 2 time periods (50.0% in 2019-2020 vs 90.0% in 2021-2022, p = 0.011). In 15 of 27 patients (55.6%) that underwent cystoscopy ± vaginoscopy, additional anomalies were found that were not identified through physical examination or US-kidney. CONCLUSIONS: In 56% of the patients that underwent cysto- ± vaginoscopy, additional anomalies were identified that were not with imaging studies or physical examination. This study emphasizes the potential benefit of routine cysto- and vaginoscopy in the diagnostic work-up of children with ARM. LEVEL OF EVIDENCE: III.

RESUMO

OBJECTIVE: The aim of this study was to determine the efficacy of a chamomile (Matricaria chamomilla) and linseed (Linum usitatissimum) saliva substitute in the relief of xerostomia in older participants. BACKGROUND: In elders, xerostomia is a permanent and progressive condition that significantly affects their quality of life. The treatment for progressive xerostomia is currently restricted to palliative measures, and saliva substitutes are indicated. A lack of evidence on the effectiveness of the saliva substitutes in the relief of symptoms of xerostomia has been reported. MATERIALS AND METHODS: Seventy-four elderly participants presenting xerostomia of diverse origin were selected. Herbal saliva substitute and carboxymethyl cellulose conventional saliva substitute were tested using a double-blind, randomised, cross-sectional clinical trial. RESULTS: Every participant of the study exhibited dry mouth sensation. A sensation of thick saliva was described in 59.5% of the participants. The need for liquid intake to swallow food, the sensation of difficulty in swallowing and the burning sensation in the tongue were observed in 54.1, 56.8 and 27.0% of the participants, respectively. The most prevalent diseases were hypertension, depressive symptoms and arthritis. Results of the clinical tests showed that the herbal saliva substitute produced a greater relief of dry mouth symptoms, thick saliva sensation and the sensation of difficulty in swallowing than the conventional substitute (Wilcoxon test p < 0.05). CONCLUSIONS: New chamomile- and linseed-based saliva substitute was effective in relieving xerostomia symptoms in older participants of this study.

RESUMO

An increased expression and activity of the heme oxygenase-1 (HO-1) in the liver has been observed in models of hepatic damage. Nitric oxide (NO) seems to be involved in HO-1 regulation. The aim of this work is to assess HO-1 induction and heme oxygenase (HO) activity in rats with bile duct ligation (BDL). We have assessed the effect of chronic inhibition of the NO synthesis by N(G)-nitro-l-arginine methyl ester (l-NAME) on HO-1 induction and HO activity. In the BDL animals, compared with sham-operated ones, we found an increased plasma nitrite and bilirubin concentration, and a marked liver expression of inducible nitric oxide synthase and HO-1, assessed by both Western blot and immunohistochemistry. Chronic l-NAME treatment prevented plasma nitrite increase in animals subjected to BDL. BDL animals treated with l-NAME, compared with untreated BDL rats, showed an important decrease in HO-1 expression and in HO activity (assessed as a decreased plasma bilirubin and bilirubin excretion). In conclusion, our experiments show parallel changes in expression and activity of HO-1 and NOS2 activity in the BDL model of liver damage and suggest that increased NO production is involved in HO-1 overexpression.

RESUMO

Bile duct ligation (BDL) in rats induces portal fibrosis. This process has been linked to changes in the oxidative state of the hepatic cells and in the production of nitric oxide. Our objective was to find possible temporal connections between hepatic redox state, NO synthesis and liver injury. In this work we have characterized hepatic lesions 17 and 31 days after BDL and determined changes in hepatic function, oxidative state, and NO production. We have also analyzed the expression and localization of inducible NO synthase (NOS2) and constitutive NO synthase (NOS3). After 17 and 31 days from ligature, lipid peroxidation is increased and both plasma concentration and biliary excretion of nitrite+nitrate are rised. 17 days after BDL both NOS2 and NOS3 are expressed intensely and in the same regions. 31 days after BDL, the expression of NOS2 remains elevated and is localized mostly in preserved hepatocytes in portal areas and in neighborhoods of centrolobulillar vein. NOS3 is localized in vascular regions of portal spaces and centrolobulillar veins and in preserved sinusoids and although its expression is greater than in control animals (34%), it is clearly lower (50%) than 17 days after BDL. The time after BDL is crucial in the study of NO production, intrahepatic localization of NOS isoforms expression, and cell type involved, since all these parameters change with time. BDL-induced, peroxidation and fibrosis are not ligated by a cause-effect relationship, but rather they both seem to be the consequence of common inductors.

RESUMO

The goal of the present study was to evaluate the role of endoglin, a transforming growth factor-beta1 (TGF-beta1) accessory receptor, in the pathogenesis of renal fibrosis. This was achieved by testing a model of tubulo-interstitial fibrosis induced by unilateral ureteral obstruction in endoglin heterozygous (Eng(+/-)) mice. Northern and Western blot analysis revealed that endoglin expression in kidneys of these mice was significantly reduced compared with Eng(+/+) littermates. Pronounced interstitial fibrosis induced by ureteral obstruction was confirmed histologically by Masson's trichromic staining and by increased immunostaining for fibronectin and laminin without significant differences between Eng(+/-) and Eng(+/+) mice. Ureteral obstruction induced significant increases in alpha2(I) and alpha1(IV) collagen, fibronectin, and TGF-beta1 mRNA levels, as well as in total kidney collagen but changes were similar in Eng(+/-) and Eng(+/+) mouse kidneys. Ureteral obstruction also induced a 2-fold increase in endoglin mRNA levels in both Eng(+/+) mice and Eng(+/-) mice, which was confirmed by Western blot analysis. Thus, the present study provides clear evidence that endoglin is upregulated in the kidneys of mice with interstitial fibrosis induced by unilateral ureteral ligation. However, Eng(+/-) mice do not show any changes in the severity of renal disease induced in this model when compared with normal mice, suggesting that the absolute level of endoglin is not critical for the effects of TGF-beta1 in the renal fibrosis process.

RESUMO

In the present study, we measured tubular cell apoptosis and proliferation and Bcl-2 expression during the early phase (3 months) of the process of renal fibrosis in the experimental model of uninephrectomized spontaneously hypertensive rats (SHR). Tubulointerstitial fibrosis was evaluated by automated quantitative morphometry using selective staining of the extracellular matrix with sirius red. Apoptosis was quantified by both in situ dUTP biotin nick end-labeling method (TUNEL) and by propidium iodide staining. Proliferation rate was measured by counting cells expressing the proliferating cell nuclear antigen. Bcl-2 expression was assessed by immunohistochemistry. Tubulointerstitial fibrosis increased progressively during the 3 months of follow-up. Proliferation and apoptosis rates in tubular cells increased from the first to the second month after UNX. In the third month after UNX, the proliferating tubular cell number continued to increase, whereas the apoptotic cell number was maintained, coinciding with an increase in the expression of Bcl-2. Our observations demonstrate a different profile of tubular cell proliferation and apoptosis during the genesis of early tubulointerstitial damage in UNX-SHR.

RESUMO

O Aleitamento materno exclusivo é uma prática fundamental para a saúde das crianças, pois fornece tudo o que a criança precisa para crescer e se desenvolver nesse período, é a estratégia que mais previne mortes infantis, além de promover a saúde física, mental e psíquica da criança (Morais, 2006). Considerando-se a importância da alimentação adequada para o crescimento normal, necessita-se promover a prática da mesma, através da realização de atividades educativas individual, em grupos e massas. Este projeto teve como objetivo elaborar um plano de ação para promover a prática do aleitamento materno na ESF IV, Forquilha, Município Canapi-AL, durante os meses de janeiro a dezembro de 2015. A metodologia executada para obter o diagnóstico situacional foi baseada no método de estimativa rápida e no Planejamento Estratégico Situacional (PES) conforme Campos, Faria, Santos (2010), assim foi possível a escolha do problema prioritário da unidade de saúde e em seguida uma revisão da literatura utilizando Base de dados da LillaCs e Sciello e selecionados os Descritores de Ciências da Saúde como: (LEVY, L; BERTOLO, H.). Neste estudo identificou-se os seguintes nós críticos: falta de entendimentos da promoção de saúde por parte de mães e familiares; e orientações inadequadas da equipe num processo de trabalho para enfrentar o problema. Nosso trabalho teve como finalidade a educação e orientação das mães sobre a importância do aleitamento materno, desenvolver um trabalho de informação para a sociedade e melhorar hábitos e estilos de vida proporcionando qualidade na mesma
