ABSTRACT
OBJECTIVE: Fractures of the proximal humerus (PHF) are commonly treated conservatively. Evidence suggests that a period of immobilization of one week or less may lead to some advantages compared to a traditional 3-4 weeks of immobilization. The purpose of this systematic review was to assess the clinical and radiological results in the case of early rehabilitation vs. delayed rehabilitation after PHF. MATERIALS AND METHODS: In July 2023, a literature search was carried out on the PubMed, MEDLINE, and Embase databases to identify all the randomized trials comparing early rehabilitation vs. delayed rehabilitation after PHF. The following data were extracted from each included study: patients' demographics, study design and level of evidence, follow-up times, treatment groups, evaluation scores adopted, and overall clinical and radiological findings. The quality of the trials was assessed using the Cochrane Risk of Bias Assessment. RESULTS: A total of 5 studies, including 378 patients and dealing with early vs. delayed rehabilitation in case of conservative treatment of PHF, were included in this study. Early rehabilitation was started within 1 week and consisted mainly of pendulum exercise and progressive passive mobilization. Early rehabilitation was associated with better pain and functional scores within the first 3 months in 3 studies. No difference in pain or function was reported at 6 months or longer follow-up, and no differences in complications rate were observed between early vs. delayed rehabilitation groups. CONCLUSIONS: This systematic review suggests that early mobilization within one week in case of conservative treatment of PHF leads to improved function recovery and reduced pain, especially in the first months of rehabilitation, without differences at longer follow-up and without increasing complications rate. Reducing immobilization time could accelerate function recovery and regaining independence in daily life activities.

OBJECTIVE: To present the functional results obtained and the possible surgical difficulties after the surgical treatment of Dupuytren's disease (DD) recurrence in patients previously treated with Clostridium histolyticum (CCH) collagenase. MATERIALS AND METHODS: In this prospective study, 178 patients with DD were treated with CCH from 2011 to 2018; During long-term postoperative follow-up, 34 patients (19.1%) had recurrence of DD. In all patients injected in the IFP the disease recurred; In patients injected in the MCP, recurrence was highest in grade III and IV of the Tubiana classification, with involvement of the 5th finger and the two-finger Y-chord. Fourteen patients (7,8%) required surgery by partial selective fasciectomy due to recurrence of cord DD infiltration. The clinical and functional results of the patients, the difficulty of the surgical technique and the anatomopathological analysis of the infiltrated cords were evaluated in comparison with those of cords and patients who had had no previous CCH treatment. RESULTS: In all patients, cord rupture was achieved after injection, reducing joint contracture. In 14 patients, we observed during the follow-up the existence of DD recurrence that required surgical treatment by selective partial fasciectomy. There were no major difficulties in surgery and good clinical and functional results at 6 months of follow-up. The anatomopathological study of the resected tissue did not present histological alterations with respect to the samples obtained from patients initially treated by selective partial fasciectomy. CONCLUSIONS: Selective fasciectomy after CCH injection does not lead to important operative difficulties, as long as the CCH injection is performed according to the recommendations. There were no histological changes in the tissue after CCH injection. LEVEL OF EVIDENCE: III.

Background Although partial onychectomy with chemical matricectomy has been described as the treatment of choice, there is sparse evidence in the literature regarding the use of silver nitrate for matricectomy. Our aim is to describe the effectiveness of silver nitrate for matrix cauterization after partial onychectomy. Methods A prospective observational study was performed on patients with ingrown toenails stage 23 who underwent partial onychectomy with silver nitrate chemical matricectomy during 20182019 in our institution. All patients were evaluated in the outpatient clinic on the 7th and 30th post-operative day and a telephone evaluation was performed every 6 months after the surgical procedure to date. Results One hundred and twenty-three patients, who underwent 231 partial onychectomies with silver nitrate chemical matricectomy were included, with a median follow-up of 21 months (interquartile range, 1229). The procedure had an effectiveness of 95.3%, with only 11 recurrences (4.7%) reported so far on follow-up. Postoperative infections were observed in 4 patients (1.7%). Adverse effects, such as pain and postoperative drainage, were irrelevant in most patients. Conclusions Silver nitrate matricectomy after partial onychectomy is an effective and safe alternative for the treatment of ingrown toenail in children, with scarce postoperative morbidity and low recurrence rate (AU)

INTRODUCTION: Our purpose with this publication is to document the survival of uncemented and unconstrained total trapeziometacarpal arthroplasty after energy trauma to the upper extremity. MATERIAL AND METHODS: From 1999 to the present, ten patients carrying total TMC arthroplasty suffered major traumatic injuries on the hand. Eight patients had fractures of the distal radius, one patient had scapho-lunate dissociation and one patient had a dorsal pullout of the triquetrum. A clinical and radiological examination of the patients after the trauma was carried out and compared with the pre-traumatic prosthesis status. RESULTS: Three patients required surgical intervention for the associated traumatic injury. The postraumatic clinical and functional follow-up of the patients was good, and no differences were documented with respect to mobility, strength and pain at the level of the thumb with respect to the prior to the trauma. No signs of loosening, instability or alteration in the alignment of the components of the protheses were observed in the radiological examinations following the trauma. CONCLUSIONS: There is a high survival rate of uncemented total trapeziometacarpal arthroplasty in the long term, even in the face of energy trauma. It is then a safe implant. Despite of being non-constrained, a good alignment of the prosthetic components is the key to avoid dislocation of the prosthesis.

Cedrela species occur within the Tropical montane cloud forest (TMCF) and rainforest in North America (Mexico), Central and South America. We assessed the hypothesis that functional xylem hydraulic architecture might be influenced by specific climatic variations. We investigated the effect of climate on tree-ring width and vessel traits (diameter, vessel density, vulnerability index and hydraulic diameter) of three relict-endemic and threatened Cedrela species (Cedrela fissilis, C. nebulosa and C. angustifolia) inhabiting Peruvian Tropical Andean cloud forests. All Cedrela species showed a significant reduction in radial growth and adjusted vessel trait linked with temperature, precipitation, and evapotranspiration. Ring-width and vessel traits showed adaptation within Cedrela species, crucial to understanding a rough indication of the plant's ability to withstand drought-induced embolism or cavitation. Our results provide evidence for hydraulic mechanisms that determine specific wood anatomical functionality to climatic variation and drought responses. Therefore, changing the frequency or intensity of future drought events might exceed the adaptive limits of TMCF tree species, resulting in a substantial reduction of hydraulic functionality in Peruvian Cedrela species.

Aim: Climate change is expected to impact mountain biodiversity by shifting species ranges and the biomes they shape. The extent and regional variation in these impacts are still poorly understood, particularly in the highly biodiverse Andes. Regional syntheses of climate change impacts on vegetation are pivotal to identify and guide research priorities. Here we review current data, knowledge and uncertainties in past, present and future climate change impacts on vegetation in the Andes. Location: Andes. Taxon: Plants. Methods: We (i) conducted a literature review on Andean vegetation responses to past and contemporary climatic change, (ii) analysed future climate projections for different elevations and slope orientations at 19 Andean locations using an ensemble of model outputs from the Coupled Model Intercomparison Project 5, and (iii) calculated changes in the suitable climate envelope area of Andean biomes and compared these results to studies that used species distribution models. Results: Future climatic changes (2040-2070) are projected to be stronger at high-elevation areas in the tropical Andes (up to 4°C under RCP 8.5), while in the temperate Andes temperature increases are projected to be up to 2°C. Under this worst-case scenario, temperate deciduous forests and the grasslands/steppes from the Central and Southern Andes are predicted to show the greatest losses of suitable climatic space (30% and 17%-23%, respectively). The high vulnerability of these biomes contrasts with the low attention from researchers modelling Andean species distributions. Critical knowledge gaps include a lack of an Andean wide plant checklist, insufficient density of weather stations at high-elevation areas, a lack of high-resolution climatologies that accommodates the Andes' complex topography and climatic processes, insufficient data to model demographic and ecological processes, and low use of palaeo data for distribution modelling. Main conclusions: Climate change is likely to profoundly affect the extent and composition of Andean biomes. Temperate Andean biomes in particular are susceptible to substantial area contractions. There are, however, considerable challenges and uncertainties in modelling species and biome responses and a pressing need for a region-wide approach to address knowledge gaps and improve understanding and monitoring of climate change impacts in these globally important biomes.
ABSTRACT
BACKGROUND: Surgical treatment of ileo-colic intussusception (ICI) has been reported as the second cause of emergency laparotomy in children. The performance of incidental appendectomy after surgical reduction is currently controversial. The aim is to analyse the outcomes of performing incidental appendectomy after surgical ICI reduction with or without associated bowel resection. MATERIALS AND METHODS: A retrospective study was performed in patients with ICI episodes, who underwent surgical treatment in our institution between 2005-2019. Patients were divided in two groups according to the performance of associated appendectomy (AA group) or not (NA group). Subsequently, a stratified analysis was performed according to the need for bowel resection in both groups. Demographic variables, intraoperative findings, surgical time, hospital stay, postoperative complications and recurrences were analysed. RESULTS: A total of 101 patients (77 AA group; 24 NA group) were included, without differences in demographics or intraoperative findings. A total of 36 bowel resections were performed (24 group AA; 10 group NA), with no differences in surgical time (55.7 min in group AA vs. 61.2 min in group NA; p = 0.587) or hospital stay (median 5 days in both groups). There were also no differences in postoperative complications or recurrences between the two groups. Stratified analysis showed that bowel resection increases operative time, hospital stay and postoperative complications, regardless of whether associated appendectomy was performed or not. CONCLUSIONS: Incidental appendectomy during surgical treatment of ICI in children is a safe procedure that does not increase operative time, hospital stay, postoperative complications or recurrence.
OBJETIVO: El tratamiento quirúrgico de la intususcepción ileocólica (IIC) es la segunda causa más frecuente de laparotomía de urgencia en niños. La realización de una apendicectomía incidental tras la reducción quirúrgica sigue siendo motivo de controversia. El objetivo de este trabajo es analizar los resultados obtenidos al llevar a cabo una apendicectomía incidental tras la reducción quirúrgica de una IIC con o sin resección intestinal asociada. MATERIAL Y METODO: Se realizó un estudio retrospectivo en pacientes con episodios de IIC sometidos a tratamiento quirúrgico en nuestro centro entre 2005 y 2019. Los pacientes se dividieron en dos grupos según se llevara a cabo apendicectomía asociada (grupo AA) o no (grupo NA). Posteriormente, se elaboró un análisis estratificado según la necesidad de practicar resección intestinal en ambos grupos. Se analizaron las variables demográficas, los hallazgos intraoperatorios, el tiempo quirúrgico, la estancia hospitalaria, las complicaciones posoperatorias y las recidivas. RESULTADOS: Se incluyeron un total de 101 pacientes (77 en el grupo AA, y 24 en el grupo NA), sin diferencias en las características demográficas ni en los hallazgos intraoperatorios. Se practicaron un total de 36 resecciones intestinales (24 en el grupo AA; 10 en el grupo NA), sin diferencias en el tiempo quirúrgico (55,7 min en el grupo AA frente a 61,2 min en el grupo NA; p = 0,587) ni en la estancia hospitalaria (mediana de 5 días en ambos grupos). Tampoco se registraron diferencias en términos de complicaciones posoperatorias o recidivas entre los dos grupos. El análisis estratificado mostró que la resección intestinal incrementa el tiempo quirúrgico, la estancia hospitalaria y las complicaciones posoperatorias, con independencia de si se lleva a cabo apendicectomía asociada o no. CONCLUSION: La apendicectomía incidental durante el tratamiento quirúrgico de la IIC en niños es un procedimiento seguro que no aumenta el tiempo quirúrgico, la estancia hospitalaria, las complicaciones posoperatorias ni las posibilidades de recidiva.

BACKGROUND AND OBJECTIVES: Since the COVID-19 pandemic confinement was established in Spain on March 9, 2020, the number of visits to the pediatric Emergency Department (ED) has decreased dramatically, probably due to the fear of parents becoming infected in the hospital environment. The aim of this work was to analyze the medium-term consequences during the first 9 months after the onset of the COVID-19 pandemic in children with acute appendicitis (AA). MATERIAL AND METHODS: A retrospective study was performed on children operated on for AA in our institution between 2017 and 2020, who were distributed in two groups according to the date of surgery: COVID-19 group (after March 9, 2020) and control group (before March 9, 2020). Demographic variables, associated symptoms, time from symptoms onset, hospital stay, rate of complicated AA and postoperative complications were analyzed. RESULTS: A total of 1274 patients were included (288 COVID group; 986 control group), without demographic differences. Time from symptom onset was significantly longer in COVID-19 group (34.5 vs. 24.2h; p=0.021), although no differences in associated symptoms were observed between both groups. COVID-19 group presented a higher rate of complicated AA (20.1% vs. 14%; OR: 1.55; CI 95% [1.10-2.18]; p=0.008), a longer hospital stay (3.5 vs. 2.8 days; p=0.042) as well as a higher rate of postoperative complications (21.5% vs. 15.7%; OR: 1.47; CI 95% [(1.06-2.04)]; p=0.008). CONCLUSION: In our experience there was a negative medium-term effects of the COVID-19 pandemic on children with acute appendicitis: delayed ED visits, increased rate of complicated AA, increased hospital stay and increased postoperative complications.

INTRODUCTION: Congenital muscular hyperplasia of the hand is a rarely described entity, characterized by the presence of aberrant or accessory muscles in the hypothenar eminence, which has been always reported as sporadic anomaly in the medical literature. The aim of this paper is to report a series of cases with a phenotype of aberrant muscle hyperplasia associated with PIK3CA mutations. MATERIAL AND METHODS: We describe a retrospective series of cases followed at our institution between 2008 and 2020, with a unique phenotypein the context of PIK3CA mutations. RESULTS: A total of 6 patients were included (4 males and 2 females), who presented with an enlargement of the hypothenar eminence of the hand and peculiar wrinkling of the overlying skin, associated with ulnar deviation of the metacarpo-phalangeal joints. In all cases, variable degrees of congenital overgrowth of the ipsilateral limb were observed. Skin punch biopsy (5 mm diameter and 3-5 mm depth) was performed on 4 patients, where striated muscle hyperplasia and the presence of striated muscular fibers in the dermis and hypodermis were observed in all of them. Genetic studies revealed PIK3CA mutation in 3 of the 4 patients whose affected tissue was analyzed, in a mosaic state ranging from 3 to 8% (His1047Arg, Glu542Lys, and Cys420Arg, 1 case each). CONCLUSION: Aberrant muscular hyperplasia of the hand is a well-recognized entity scarcely described in association with PIK3CA spectrum disorder in the pediatric population. The role of PIK3CA in muscle overgrowth is not yet well understood.
INTRODUCCION: La hiperplasia muscular congénita de la mano es una entidad rara, caracterizada por la presencia de músculos aberrantes o accesorios en la eminencia hipotenar, que siempre se ha descrito en la literatura médica como una anomalía esporádica. El objetivo de este artículo es informar de una serie de casos con fenotipo de hiperplasia muscular aberrante asociada a mutaciones del PIK3CA. MATERIAL Y METODOS: Serie retrospectiva de casos atendidos en nuestro centro entre 2008 y 2020, con un fenotipo único en el contexto de las mutaciones del PIK3CA. RESULTADOS: Se incluyeron un total de 6 pacientes (4 masculinos y 2 femeninos) con ensanchamiento de la eminencia hipotenar de la mano y arrugamiento peculiar de la piel suprayacente, asociado a desviación ulnar de las articulaciones metacarpofalángicas. En todos los casos se observaron grados variables de sobrecrecimiento congénito del miembro ipsilateral. Se realizó biopsia cutánea por punch (5 mm de diámetro y 3-5 mm de profundidad) en 4 pacientes con hiperplasia muscular y presencia de fibras musculares estriadas en dermis e hipodermis. Los estudios genéticos revelaron mutación del PIK3CA en 3 de los 4 pacientes, cuyo tejido afectado fue enviado a analizar, con mosaicismo de entre el 3 y el 8% (His1047Arg, Glu542Lys y Cys420Arg respectivamente). CONCLUSION: La hiperplasia muscular aberrante de la mano es una entidad reconocida pero escasamente descrita en asociación con síndromes relacionados con el PIK3CA en la población pediátrica. A día de hoy sigue desconociéndose el papel del PIK3CA en el sobrecrecimiento muscular.
