RESUMO

Background: Open hindfoot surgery is associated with a relatively high rate of complications, including neurovascular injuries and wound healing problems compared with percutaneous techniques. However, there is a scarcity of literature describing the outcomes of these percutaneous techniques given their relatively recent adoption. The present study aims to assess the rate of postoperative complications for 3 commonly performed percutaneous calcaneal osteotomies. Methods: One hundred eighteen patients (unilateral feet) were treated with one of 3 common percutaneous calcaneal osteotomies. Sixty-five patients (55.1%) were treated with a medializing calcaneal osteotomy for hindfoot valgus, 32 patients with a Zadek osteotomy (27.1%) for insertional Achilles tendinopathy, and 21 patients (17.8%) with a modified Dwyer osteotomy for hindfoot varus. Fisher exact test was used to assess for associations between categorical variables. Results: The mean age was 46.2 years and there was a mean follow-up of 16.1 months. The overall rate of postoperative complications was 3.4% (n = 4), and no significant differences were found between the different osteotomy types. Complications included 2 cases (1.7%) of transient neuritis, 1 case of prolonged wound drainage (0.8%), and 1 nonunion (0.8%). None of the complications were associated with any recorded preoperative comorbidity. Discussion: In this series, we found that percutaneous calcaneal osteotomies are a safe alternative method for the treatment of conditions involving the hindfoot. The rate of postoperative complications may be less when compared to the reported rates of open hindfoot correction and should be considered in patients with a traditionally high risk of developing a postoperative complication. Level of Evidence: Level IV, retrospective analysis.

RESUMO

A 73-year-old woman with significant medical comorbidities presented with a grade I open left ankle fracture dislocation. Distraction arthroplasty was used as a definitive treatment for this injury. The patient tolerated the procedure and had no postoperative complications. The external fixator was removed at 6 months. The patient maintained good ankle function at the 1-year postoperative visit. Distraction arthroplasty is a viable acute and definitive treatment option for ankle fracture in patients with significant medical comorbidities. [Orthopedics. 2021;44(1):e148-e150.].

RESUMO

(1) Background: Memory deficits are common sequelae of pediatric Acquired Brain Injury (ABI). Only methods for non-focused cognitive remediation are available to the pediatric field. The aims of this feasibility trial are the description, implementation, and test of an intensive program specific to the training and re-adaptation of memory function in children, called Intensive Memory-Focused Training Program (IM-FTP); (2) Methods: Eleven children and adolescents with ABI (mean age at injury = 12.2 years, brain tumor survivors excluded) were clinically assessed and rehabilitated over 1-month through IM-FTP, including physio-kinesis/occupational, speech, and neuropsychology treatments. Each patient received a psychometric evaluation and a brain functional MRI at enrollment and at discharge. Ten pediatric controls with ABI (mean age at injury = 13.8 years) were clinically assessed, and rehabilitated through a standard program; (3) Results: After treatment, both groups had marked improvement in both immediate and delayed recall. IM-FTP was associated with better learning of semantically related and unrelated words, and larger improvement in immediate recall in prose memory. Imaging showed functional modification in the left frontal inferior cortex; (4) Conclusions: We described an age-independent reproducible multidisciplinary memory-focused rehabilitation protocol, which can be adapted to single patients while preserving inter-subject comparability, and is applicable up to a few months after injury. IM-FTP will now be employed in a powered clinical trial.

RESUMO

Surgeries involving the foot and ankle are painful procedures, with many patients unwilling to discontinue prescribed narcotics at 3 months postoperatively. Percutaneous techniques allow for smaller incisions and minimal soft tissue disruption. Fifty consecutive patients underwent outpatient percutaneous foot surgery. Data were collected on pain medication taken and time to return to work. A mean of 3.3 tablets of oxycodone were consumed during the first 2 weeks. No patient was taking narcotics after 2 weeks. Mean time to return to work was 18.9 days. Percutaneous foot and ankle surgery led to a significant reduction in narcotic consumption. [Orthopedics. 2020;43(4):e334-e337.].

RESUMO

BACKGROUND: Insertional Achilles tendinopathy (IAT) is a challenging common lower extremity disorder, despite several treatment options described in literature. Open dorsal closing wedge calcaneal osteotomy or Zadek Osteotomy (ZO), for the treatment of the IAT has good clinical results but a high rate of postoperative complications. The purpose of this study is to describe percutaneous ZO for the treatment of the IAT and to evaluate its impact on the clinical and functional postoperative outcomes. METHODS: Twenty-six consecutive patients presenting with unilateral IAT refractory to nonoperative measures were treated with percutaneous ZO. Visual Analogue Scale (VAS) and Foot Function Index Score (FFI) were recorded preoperatively and at final follow-up visit (12±3) months. Postoperative complications, satisfaction, and relief of the pain were also recorded. RESULTS: The percutaneous ZO showed a significant improvement (p<0.0001) in preoperative to postoperative FFI (from 65±9 to 8±12) and VAS (from 9±1 to 1±2). Two postoperative complications (8%) were observed: a case of symptomatic non-union and hardware pain, both in healthy patients. The overall rate of satisfaction after surgery was (92%). The relief from pain was achieved after an average period of 12 weeks. CONCLUSIONS: ZO is a safe and effective procedure for the treatment of IAT. The use of a minimally invasive surgical approach is associated with excellent pain reduction (VAS score) and improved clinical function (FFI score). When compared to the open surgical approach, the percutaneous ZO may decrease recovery time and postoperative complications. LEVEL OF EVIDENCE: III, retrospective case series.

RESUMO

First metatarsophalangeal (MTP) joint arthrodesis is a treatment option for patients with arthritic hallux valgus (HV). Nickel-titanium staples allow continuous compression throughout the fusion site and have been shown to achieve successful union in many procedures. However, their efficacy has not been tested in patients with underlying HV deformity. Three cases of severe HV deformity that underwent first MTP arthrodesis with 2 nickel-titanium staples placed 60° from each other and had failure are reported. The authors believe this construct does not provide adequate rotational control for first MTP arthrodesis in patients with severe HV deformity. [Orthopedics. 2019; 42(4):e402-e404.].

RESUMO

We describe the results of a functional and structural brain connectivity analysis comparing a homogeneous group of 10 young adults with Williams Syndrome (WS; 3 females, age 20. 7 ± 3.7 years, age range 17.4-28.7 years) to a group of 18 controls of similar age (3 females, age 23.9 ± 4.4 years, age range 16.8-30.2), with the aim to increase knowledge of the structure - function relationship in WS. Subjects underwent a 3T brain MRI exam including anatomical, functional (resting state) and structural (diffusion MRI) sequences. We found convergent anomalies in structural and functional connectivity in the WS group. Altered Fractional Anisotropy (FA) values in parieto-occipital regions were associated with increased connectivity in the antero-posterior pathways linking parieto-occipital with frontal regions. The analysis of resting state data showed altered functional connectivity in the WS group in main brain networks (default mode, executive control and dorsal attention, sensori-motor, fronto-parietal, ventral stream). The combined analysis of functional and structural connectivity displayed a different pattern in the two groups: in controls the highest agreement was found in frontal and visual areas, whereas in WS patients in posterior regions (parieto-occipital and temporal areas). These preliminary findings may reflect an altered "wiring" of the brain in WS, which can be driven by hyper-connectivity of the posterior regions as opposed to disrupted connectivity in the anterior areas, supporting the hypothesis that a different brain (organization) could be associated with a different (organization of) behavior in Williams Syndrome.

RESUMO

Friedreich's ataxia (FRDA) is a rare hereditary neurodegenerative disorder caused by a GAA repeat expansion in the FXN gene. There is still no cure or quantitative biomarkers reliaby correlating with the progression rate and disease severity. Investigation of functional and structural alterations characterizing white (WM) and gray matter (GM) in FRDA are needed prerequisite to monitor progression and response to treatment. Here we report the results of a multimodal cross-sectional MRI study of FRDA including Voxel-Based Morphometry (VBM), diffusion-tensor imaging (DTI), functional MRI (fMRI), and a correlation analysis with clinical severity scores. Twenty-one early-onset FRDA patients and 18 age-matched healthy controls (HCs) were imaged at 3T. All patients underwent a complete cognitive and clinical assessment with ataxia scales. VBM analysis showed GM volume reduction in FRDA compared to HCs bilaterally in lobules V, VI, VIII (L>R), as well as in the crus of cerebellum, posterior lobe of the vermis, in the flocculi and in the left tonsil. Voxel-wise DTI analysis showed a diffuse fractional anisotropy reduction and mean, radial, axial (AD) diffusivity increase in both infratentorial and supratentorial WM. ROI-based analysis confirmed the results showing differences of the same DTI metrics in cortico-spinal-tracts, forceps major, corpus callosum, posterior thalamic radiations, cerebellar penduncles. Additionally, we observed increased AD in superior (SCP) and middle cerebellar peduncles. The WM findings correlated with age at onset (AAO), short-allelle GAA, and disease severity. The intragroup analysis of fMRI data from right-handed 14 FRDA and 15 HCs showed similar findings in both groups, including activation in M1, insula and superior cerebellar hemisphere (lobules V-VIII). Significant differences emerged only during the non-dominant hand movement, with HCs showing a stronger activation in the left superior cerebellar hemisphere compared to FRDA. Significant correlations were found between AAO and the fMRI activation in cerebellar anterior and posterior lobes, insula and temporal lobe. Our multimodal neuroimaging protocol suggests that MRI is a useful tool to document the extension of the neurological impairment in FRDA.

RESUMO

Cardiomyocyte proliferation stops at birth when the heart is no longer exposed to maternal blood and, likewise, to regulatory T cells (Tregs) that are expanded to promote maternal tolerance towards the fetus. Here, we report a role of Tregs in promoting cardiomyocyte proliferation. Treg-conditioned medium promotes cardiomyocyte proliferation, similar to the serum from pregnant animals. Proliferative cardiomyocytes are detected in the heart of pregnant mothers, and Treg depletion during pregnancy decreases both maternal and fetal cardiomyocyte proliferation. Treg depletion after myocardial infarction results in depressed cardiac function, massive inflammation, and scarce collagen deposition. In contrast, Treg injection reduces infarct size, preserves contractility, and increases the number of proliferating cardiomyocytes. The overexpression of six factors secreted by Tregs (Cst7, Tnfsf11, Il33, Fgl2, Matn2, and Igf2) reproduces the therapeutic effect. In conclusion, Tregs promote fetal and maternal cardiomyocyte proliferation in a paracrine manner and improve the outcome of myocardial infarction.

RESUMO

The near-total absence of the cerebellum is a rare congenital condition with a wide phenotypic heterogeneity ranging from a severe to mild impairment of motor, cognitive, and behavioral functions. In this study, the case of a 48-year-old right-handed man with a near-total absence of the cerebellum was examined with the aim of understanding the long-term reorganization of a brain developed without a cerebellum. Clinical, neuropsychological evaluation and a neuroimaging study on a 3-T scanner were carried out. Both conventional structural diffusion tensor imaging (DTI) and functional (resting-state fMRI) data were acquired. A severe neuropsychomotor delay in infancy and adolescence involving motor skills, cognitive, and affective competencies was observed, which improved over the years. Conventional MRI findings confirmed the complete absence of the cerebellum. Analysis of DTI and resting-state fMRI data showed an impairment of the executive-control network, involving areas strongly connected with the cerebellum through the frontopontine fibers. The neuroimaging findings excluded the involvement of the extracerebellar structure. In conclusion, our data support the vascular genesis hypothesis for this rare pathology, consistent with an acquired embryonic cerebellar insult. This case also shows that it is possible to learn to live without the cerebellum over time.

RESUMO

The mechanisms involved in the development of severe angioobliterative pulmonary arterial hypertension (PAH) are multicellular and complex. Many of the features of human severe PAH, including angioobliteration, lung perivascular inflammation, and right heart failure, are reproduced in the Sugen 5416/chronic hypoxia (SuHx) rat model. Here we address, at first glance, the confusing and paradoxical aspect of the model, namely, that treatment of rats with the antiangiogenic vascular endothelial growth factor (VEGF) receptor 1 and 2 kinase inhibitor, Sugen 5416, when combined with chronic hypoxia, causes angioproliferative pulmonary vascular disease. We postulated that signaling through the unblocked VEGF receptor VEGFR3 (or flt4) could account for some of the pulmonary arteriolar lumen-occluding cell growth. We also considered that Sugen 5416-induced VEGFR1 and VEGFR2 blockade could alter the expression pattern of VEGF isoform proteins. Indeed, in the lungs of SuHx rats we found increased expression of the ligand proteins VEGF-C and VEGF-D as well as enhanced expression of the VEGFR3 protein. In contrast, in the failing right ventricle of SuHx rats there was a profound decrease in the expression of VEGF-B and VEGF-D in addition to the previously described reduction in VEGF-A expression. MAZ51, an inhibitor of VEGFR3 phosphorylation and VEGFR3 signaling, largely prevented the development of angioobliteration in the SuHx model; however, obliterated vessels did not reopen when animals with established PAH were treated with the VEGFR3 inhibitor. Part of the mechanism of vasoobliteration in the SuHx model occurs via VEGFR3. VEGFR1/VEGFR2 inhibition can be initially antiangiogenic by inducing lung vessel endothelial cell apoptosis; however, it can be subsequently angiogenic via VEGF-C and VEGF-D signaling through VEGFR3.

RESUMO

BACKGROUND: Sterile inflammation resulting from myocardial injury activates the NLRP3 inflammasome and amplifies the inflammatory response mediating further damage. METHODS: We used 2 experimental models of ischemic injury (acute myocardial infarction [AMI] with and without reperfusion) and a model of nonischemic injury due to doxorubicin 10 mg/kg to determine whether the NLRP3 inflammasome preserved cardiac function after injury. RESULTS: Treatment with the NLRP3 inflammasome inhibitor in the reperfused AMI model caused a significant reduction in infarct size measured at pathology or as serum cardiac troponin I level (-56% and -82%, respectively, both P < 0.001) and preserved left ventricular fractional shortening (LVFS, 31 ± 2 vs. vehicle 26% ± 1%, P = 0.003). In the non-reperfused AMI model, treatment with the NLRP3 inhibitor significantly limited LV systolic dysfunction at 7 days (LVFS of 20 ± 2 vs. 14% ± 1%, P = 0.002), without a significant effect on infarct size. In the doxorubicin model, a significant increase in myocardial interstitial fibrosis and a decline in systolic function were seen in vehicle-treated mice, whereas treatment with the NLRP3 inhibitor significantly reduced fibrosis (-80%, P = 0.001) and preserved systolic function (LVFS 35 ± 2 vs. vehicle 27% ± 2%, P = 0.017). CONCLUSIONS: Pharmacological inhibition of the NLRP3 inflammasome limits cell death and LV systolic dysfunction after ischemic and nonischemic injury in the mouse.

RESUMO

Complex Regional Pain Syndrome (CRPS) is a chronic pain condition that occurs after a tissue injury (fractures, sprain, surgery) of the upper or lower extremities. A clear pathophysiological mechanism has not been established yet and different patterns are considered to play a role in the genesis of the disease. The diagnosis is made by different diagnosis criteria and a gold standard has not been established yet. Incidence of CRPS is unclear and large prospective studies on the incidence and prevalence of CRPS are scarce. The aim of this review is to give an overview on the prevalent data regarding this chronic syndrome.

RESUMO

AIMS: To evaluate the long-term changes of clinical and echocardiographic parameters, the incidence of cardiac events and parameters associated with late cardiac events in 'super-responders' to cardiac resynchronization therapy (CRT) with [CRT defibrillator (CRT-D)] or without defibrillator back-up. METHODS AND RESULTS: In all consecutive patients treated with CRT in two Italian centres (Trieste and Udine) with left ventricular ejection fraction (LVEF) ≤0.35 at implantation (Timp) and LVEF > 0.50 1 and/or 2 years (Tnorm) after implantation, the long-term outcome and the evolution of echocardiographic parameters were assessed; factors associated with a higher risk of cardiac events, defined as hospitalization or death for heart failure (HF), sudden death, or CRT-D appropriate interventions, were also analysed. Among the 259 patients evaluated, 62 (24%) had LVEF ≥ 0.50 at Tnorm (n = 44 with at 1 year, n = 18 at 2 years). During a mean follow-up of 68 ± 30 months, one cardiac death (for HF) and eight cardiovascular events (two hospitalization for HF and six appropriate CRT-D interventions) occurred. At the last echo evaluation (Tfup) performed 51 ± 26 months after Timp, LVEF was <0.50 in five patients (>0.45 in four of them). At univariable analysis, only LV end-systolic volume evaluated at Tfup was associated with a higher risk of cardiac events during follow-up. CONCLUSION: In 'super-responders' to CRT long-term outcome is excellent. However, cardiac events, mainly CRT-D appropriate interventions, can occur despite the persistence of LVEF > 0.50. Early identification of these patients is still an unsolved issue.

RESUMO

A case of thyroid metastasis of a renal clear cell carcinoma is presented. The fine-needle aspiration cytology pointed out the primary tumor origin. The patient underwent robot-assisted radical nephrectomy and contextual thyroidectomy. During the operative procedure, a neoplastic thrombus extending from the thyroid metastasis and protruding into the internal jugular vein was found. As a result, thrombectomy and ligation of the internal jugular vein were required. In cases of single synchronous thyroid metastases form RCC, radical surgery should be advisable. Robotic approach allows to associate major surgery procedures, as nephrectomy, with radical metastasectomy.

RESUMO

OBJECTIVES: Aim of the study is to verify if a stress reaction due to G8 meeting, held in Genoa on July 2001, can produce a mass stress reaction and influence negatively people sexuality and so the birth rate. MATERIALS AND METHODS: 402 citizens (221 men and 181 women ranging in age from 25 to 52 years, mean 39) have been invited to answer two questionnaires concerning their sexual activity and their feelings before, during and after the G8 meeting. After 9,10 and 11 months we have valued the birth rate in Genoa. RESULTS: 30 people (7%) did not answer the two questionnaires. 12 people (3%) answered the questionnaire wrongly and were excluded from the study. 228 people (63%) didn't report changes about their sexual activity, during G8 meeting. 120 people (33%) reported a decrease of sexual intercourses and of sexual desire; 12 people (4%) reported an increase of these parameters. 54% of our population reported a definite anxiety. We want to emphasize the high number of people that had anxiety even in the group that didn't report changes in sexual activity (105/228 = 46%). After 9, 10 and 11 months we have recorded a significant decrease of the birth rate respectively of 29%, 23%, 20%. (P < 0.05). CONCLUSIONS: Violent demonstrations during G8 meeting have negatively influenced people sexual activity and people behaviour. Besides, we have recorded a decrease of birth rate in Genoa, nine, ten and eleven months after G8. This decrease rate was respectively 29%-23%-20% as regards the same months during the three years before (P < 0.05). We cannot determine the real cause of this decrease. Violent G8 demonstrations could be responsible for a stress reaction with negative consequences on human reproductive functions.
