RESUMEN

INTRODUCTION: shoulder plain is a common cause of complain, however a precise diagnosis is hard to achieve. This is why finding factors associated to a good prognosis could help to improve our clinical practice. OBJECTIVE: to identify demographic and clinical characteristics from the initial assessment associated with substantial clinical benefit (SCB) in patients with shoulder pain one month after treatment or at patient's discharge. MATERIAL AND METHODS: this was a secondary analysis of a prospective cohort of patients with shoulder pain. Demographic and clinical (self-reported scales) factors associated with SCB at discharge or four weeks after the initial assessment, were analyzed. SCB was defined as a score +5 on a Global Rating of Change. A logistic regression model was made in order to identify predictors of SCB. The area under the curve ROC was used to assess the performance of the model with its independent variables. RESULTS: 101 patients of 138 were analyzed. The median age was 55 (RIQ 37-61) years old, there were 55 (54.5%) women in the sample. The variables independently associated to SCB were fracture as a reason for admission [adjusted OR 11.8 (95% CI 1.4-101.8); p = 0.024], and durations of shoulder symptoms shorter than seven months [adjusted OR 4.63 (95% CI 1.9-11.1); p = 0.001]. CONCLUSION: the diagnosis of fracture and durations of shoulder symptoms shorter than seven months were independently associated with a SCB after one month of treatment or at the patient's discharge.


INTRODUCCIÓN: las patologías de hombro representan una condición clínica frecuente, pero suele ser complejo realizar un diagnóstico preciso. Es por esto, que conocer qué variables permiten realizar un pronóstico del resultado del tratamiento puede ser útil para la práctica clínica. OBJETIVO: el objetivo del presente estudio fue identificar características clínicas y demográficas asociadas a beneficio clínico sustancial (BCS) en pacientes con afecciones musculoesqueléticas de hombro al mes o al alta del inicio de tratamiento fisioterápico. MATERIAL Y MÉTODOS: se realizó un análisis secundario de una cohorte prospectiva de pacientes con dolor de hombro. Se evaluó qué factores demográficos y clínicos se asociaban a BCS. Se consideró BCS un puntaje +5 en la Global Rating of Change. Se realizó un modelo de regresión logística para identificar predictores de BCS. A su vez, se utilizó el área bajo de la curva ROC para determinar el desempeño del modelo con sus respectivas variables independientes. RESULTADOS: de 138 sujetos se analizaron 101 pacientes. La mediana de edad fue de 55 (RIQ 37-61) años, hubo 55 (54.5%) mujeres dentro de la muestra. Las variables que se asociaron independientemente a BCS fueron fractura como motivo de ingreso [OR ajustado 11.8 (IC95% 1.4-101.8); p = 0.024] y tiempo de evolución menor a siete meses [OR ajustado 4.63 (IC95% 1.9-11.1); p = 0.001]. CONCLUSIÓN: el diagnóstico de fractura y el tiempo de evolución menor a siete meses se asociaron de manera independiente a BCS al cumplir un mes de tratamiento kinésico o al alta.

RESUMEN

Background: Congenital hypothyroidism (CH) is the most common congenital endocrine disease with reported high prevalence of associated congenital anomalies which are also present in case of congenital cytomegalovirus (cCMV) infection. Subjects and Methods: We present two cases of newborns cCMV infection with CH. In the first case thyroid agenesis was diagnosed and cCMV infection was also confirmed for the hypotonia persistence after L-thyroxine treatment. In the second case thyroid dyshormonogenesis was diagnosed with maternal CMV serological conversion in the first trimester of gestation and confirmed post-neonatal infection. Incidence of CH has increased in the Italian region of Piedmont in the years 2014-2019 up to 1:1090 with higher incidence of cCMV infection in the babies with diagnosis of CH (12/1000 vs. 5-7/1000 in the newborns without CH). To our knowledge, no data on the association of cCMV infection with a CH condition have been reported in the literature to date. Conclusions: The described cases could be useful to alert caregivers in case of maternal seroconversion to avoid maternal and foetal hypothyroidism. On the other hand, when the clinical condition of newborns with CH diagnosis do not improve after l-thyroxine treatment, it might be important to consider cCMV infection.

RESUMEN

Vitis vinifera L. is an economically important crop that can be influenced by soil microorganisms, including arbuscular mycorrhizal fungi (AMF), that establish symbiotic associations with its roots. AMF have beneficial effects on grapevine performance improving water use efficiency and replant success. Most grapevine varieties are susceptible to various diseases, and integrated pest management (IPM) is one of the emerging approaches to perform pest control. In the present study, we examined the AMF communities present in the soil associated to the roots of V. vinifera cv. Pinot Noir (comparing them to those present in a soil not affected by grapevine roots), in a vineyard subjected to IPM at two different phenological stages, using 454 Roche sequencing technology. We proposed a new approach to analyze sequencing data. Most of the taxa were included in the family Glomeraceae. In particular, Glomus sp. Rhizophagus sp. and Septoglomus viscosum were present. The family Archeosporaceae was represented only by the genus Archeospora sp. Different AMF communities were found in the two soils and the importance of the phenological stage in regulating AMF biodiversity was assessed.

RESUMEN

The rhizosphere is a hotspot of microbial activity where the release of root exudates stimulates bacterial density and diversity. The majority of the bacterial cells in soil are viable, unculturable, but active. Proteomic tools could be useful in gaining information about microbial community activity and to better understand the real interactions between roots and soil. The aim of this work was to characterize the bacterial community associated with Vitis vinifera cv. Pinot Noir roots using a metaproteome approach. Our results confirmed the large potential of proteomics in describing the environmental microbial communities and their activities: in particular, we showed that bacteria belonging to Streptomyces, Bacillus, Bradyrhizobium, Burkholderia and Pseudomonas genera are the most active in protein expression. Concerning the biological activity of these genera in the rhizosphere, we observed the exclusive presence of the phosphorus metabolic process and the regulation of primary metabolic processes. To our knowledge, this is the first study reporting the rhizosphere proteome of V. vinifera, describing the bacterial community structure and activity of an important ecosystem for the Italian landscape, agriculture and economy.

RESUMEN

Drug-resistant paediatric tuberculosis (TB) is an overlooked global problem. In Italy, the epidemiology of TB has recently changed and data regarding drug-resistant forms in the paediatric setting is scanty. The aim of this case series was to report the cases of drug-resistant TB, diagnosed between June 2006 and July 2010 in four Italian tertiary centres for paediatric infectious diseases, in children and adolescents living in Italy. Twenty-two children were enrolled, of these 17 were resistant to one or more drugs and five had multidrug-resistant TB. All but one child were either foreign born or had at least one foreign parent. Twenty-one patients completed their treatment without clinical or radiological signs of activity at the end of treatment, and one patient was lost to follow up. The outcomes were good, with few adverse effects using second-line anti-TB drugs. Although this series is limited, it might already reflect the worrisome increase of drug-resistant TB, even in childhood.

RESUMEN

Tuberculosis keeps on representing a serious threat worldwide and one of the major challenge of our century. Different strategies have been developed in order to eradicate the disease, and particular attention is paid to children, who are at great risk for developing severe manifestations and poor outcome. Age at exposure, nutritional conditions and immune status can lead to great variability of disease expressions, with subsequent difficulties in making an appropriate and rapid diagnosis. Moreover, children coming from tuberculosis-endemic areas should be carefully evaluated for M. tuberculosis infection. Here we present a infrequent manifestation of extrapulmonary tuberculosis in a 13-years-old girl coming from Latin America: a superficial persistent cervical lymphadenopathy was associated with a totally asymptomatic retropharyngeal abscess. Diagnostic approach was discussed. Treatment consisted with a combination of surgical drainage of the abscess and a prolonged combined 6-month chemotherapy. The cervical lymphadenopathy disappeared and no relapses were found during the subsequent follow up.

RESUMEN

This prospective observational study was designed to assess the incidence of, risk factors for, and outcome of catheter-related bloodstream infection in children undergoing cardiac surgery. A staff specifically trained to handle the central venous catheters with proper aseptic techniques and an appropriate patient to medical staff ratio remain the most effective measures to prevent this infection.

RESUMEN

Bartonella henselae is the causative agent of cat-scratch disease and other disorders, including hepatosplenic granulomatosis. This infection has only rarely been reported after solid organ transplantation, where it can mimic the more common post-transplant lymphoproliferative disease. Here we present a case of asymptomatic B. henselae hepatic and lymph nodal granulomatosis in a pediatric patient who had received orthotopic liver transplant 2 months before; we hypothesize that the causative agent was transmitted from the donor. This infection developed early in the post-transplant period; the disease involved only the graft liver and the regional lymph nodes, and the patient did not have a cat or any history of contact, scratches, or bites by a cat. In our patient this infection resolved successfully with a combination of 2 associated antibiotics and reduction of immunosuppressive therapy.

RESUMEN

MOTIVATION: Alternative splicing has recently emerged as a key mechanism responsible for the expansion of transcriptome and proteome complexity in human and other organisms. Although several online resources devoted to alternative splicing analysis are available they may suffer from limitations related both to the computational methodologies adopted and to the extent of the annotations they provide that prevent the full exploitation of the available data. Furthermore, current resources provide limited query and download facilities. RESULTS: ASPicDB is a database designed to provide access to reliable annotations of the alternative splicing pattern of human genes and to the functional annotation of predicted splicing isoforms. Splice-site detection and full-length transcript modeling have been carried out by a genome-wide application of the ASPic algorithm, based on the multiple alignments of gene-related transcripts (typically a Unigene cluster) to the genomic sequence, a strategy that greatly improves prediction accuracy compared to methods based on independent and progressive alignments. Enhanced query and download facilities for annotations and sequences allow users to select and extract specific sets of data related to genes, transcripts and introns fulfilling a combination of user-defined criteria. Several tabular and graphical views of the results are presented, providing a comprehensive assessment of the functional implication of alternative splicing in the gene set under investigation. ASPicDB, which is regularly updated on a monthly basis, also includes information on tissue-specific splicing patterns of normal and cancer cells, based on available EST sequences and their library source annotation.

RESUMEN

In this work we describe the process that, starting with the production of human full-length-enriched cDNA libraries using the CAP-Trapper method, led us to the discovery of 342 putative new human genes. Twenty-three thousand full-length-enriched clones, obtained from various cell lines and tissues in different developmental stages, were 5'-end sequenced, allowing the identification of a pool of 5300 unique cDNAs. By comparing these sequences to various human and vertebrate nucleotide databases we found that about 40% of our clones extended previously annotated 5' ends, 662 clones were likely to represent splice variants of known genes, and finally 342 clones remained unknown, with no or poor functional annotation. cDNA-microarray gene expression analysis showed that 260 of 342 unknown clones are expressed in at least one cell line and/or tissue. Further analysis of their sequences and the corresponding genomic locations allowed us to conclude that most of them represent potential novel genes, with only a small fraction having protein-coding potential.

RESUMEN

The crucial role of the non-coding portion of genomes is now widely acknowledged. In particular, mRNA untranslated regions are involved in many post-transcriptional regulatory pathways that control mRNA localization, stability and translation efficiency. We review in this paper the major structural and compositional features of eukaryotic mRNA untranslated regions and provide some examples of bioinformatic analyses for their functional characterization.

RESUMEN

The authors assess the efficacy of gold salt treatment for juvenile rheumatoid arthritis. The study was carried out on 16 children suffering from mono-pauciarticular, polyarticular and systemic arthritis. Treatment consisted of the administration of auranofin alone in a group of 8 children and auranofin associated to corticosteroids in a second group of 8 children. A marked improvement in clinical conditions was observed with slight transitory side effects at follow-up after 12 and 24 months.

RESUMEN

The effectiveness of some anti-inflammatory drugs has been compared in a series of 35 patients suffering from infant rheumatoid arthritis at onset and at the third month of disease. The results show that the clinical response to the various therapeutic protocols differs with the protocol and the stage of the disease in consideration, that disease monitoring in the early stage benefits from the serological examinations and that there is a low incidence of significant side-effects.
