Dermoscopy of cutaneous smooth muscle neoplasms: a morphological study of 136 cases
2019
BACKGROUND: A variety of cutaneous smooth muscle neoplasms may arise in the skin and are frequently unrecognized by clinicians. There is sparse data relating to the dermoscopy of piloleiomyomas (PL), and nothing has been published about the dermoscopy of angioleiomyomas (AL) and leiomyosarcomas (LS). OBJECTIVES: To evaluate the morphological findings of a large series of cutaneous PL, AL and LS under dermoscopic observation, comparing these findings among them. METHODS: Digital dermoscopic images of 136 histopathologically confirmed cases of cutaneous smooth muscle neoplasms (114 PL, 13 AL and 9 LS) collected from 10 Hospitals in Spain, Austria and Italy were evaluated for the presence of d…
A manual therapy and home stretching program in patients with primary frozen shoulder contracture syndrome : a case series
2019
Abstract: Background Manual therapy has been demonstrated to reduce pain and improve function in patients with frozen shoulder contracture syndrome (FSCS), but no evidence exists to support one form of manual therapy over another. The purpose of this case series was to describe both short and long-term outcomes after a manual therapy program and home stretching exercises based on specific impairments in shoulder mobility and level of tissue irritability in patients with FSCS. Case Description Eleven patients with primary FSCS were treated with an individually tailored multimodal manual therapy approach once weekly for 12 visits coupled with home stretching exercises once a day, five days pe…
Effect of a distal weight-bearing implant on visual analog scale scores in 23 transfemoral amputees.
2018
The objective of this interrupted time series clinical trial was to evaluate the effect of a distal weight-bearing implant on well-being in patients with transfemoral amputations using the visual analog scale (VAS). A total of 29 patients from five hospitals with previous transfemoral amputations were surgically implanted with an osseoanchored implant with a distal spacer that allows a direct load on the residuum over the distal surface of the socket. Patients were followed for a 14-month period and assessed presurgically and postsurgically using the VAS. The Wilcoxon test was used to evaluate the differences between variables. VAS mean scores improved significantly after intervention. Sign…
An Information-Theoretic Framework to Map the Spatiotemporal Dynamics of the Scalp Electroencephalogram
2016
We present the first application of the emerging framework of information dynamics to the characterization of the electroencephalography (EEG) activity. The framework provides entropy-based measures of information storage (self entropy, SE) and information transfer (joint transfer entropy (TE) and partial TE), which are applied here to detect complex dynamics of individual EEG sensors and causal interactions between different sensors. The measures are implemented according to a model-free and fully multivariate formulation of the framework, allowing the detection of nonlinear dynamics and direct links. Moreover, to deal with the issue of volume conduction, a compensation for instantaneous e…
Lag-specific transfer entropy as a tool to assess cardiovascular and cardiorespiratory information transfer
2014
In the study of interacting physiological systems, model-free tools for time series analysis are fundamental to provide a proper description of how the coupling among systems arises from the multiple involved regulatory mechanisms. This study presents an approach which evaluates direction, magnitude, and exact timing of the information transfer between two time series belonging to a multivariate dataset. The approach performs a decomposition of the well-known transfer entropy (TE) which achieves 1) identifying, according to a lag-specific information-theoretic formulation of the concept of Granger causality, the set of time lags associated with significant information transfer, and 2) assig…
Age of onset of episodic and chronic cluster headache – a review of a large case series from a single headache centre
2016
Background In the largest case series of cluster headache (CH) published in the literature, age of onset varies between 29.6 and 31.6 years. Differences in onset age based on gender and subtype diagnosis are reported, while there are only few data on patients with childhood and elderly onset. We therefore deemed it useful to review our own large case series of CH patients. Methods The age of onset of cluster headache was investigated in a consecutive case series of 808 patients (585 men and 223 women), including 686 (503 men and 183 women) with episodic cluster headache (ECH), 103 (66 men and 37 women) with chronic cluster headache (CCH), and 19 with an indeterminate form of CH (16 men and …
Oral peripheral ameloblastoma: A retrospective series study of 25 cases
2018
Background Peripheral ameloblastoma (PA) is a rare and unusual variant of odontogenic tumor, which was described only in isolated case reports in literature. The objective of this study was to investigate the clinical profile, treatment and outcome of PA in a consecutive case series. Material and Methods A total of 25 patients with histologically confirmed PA from 2001 to 2015 were retrospectively reviewed in our institution. Results Of the 25 patients, 22 males and 3 females were identified (male: female = 7.3:1). The average age was 48.3 years (range 11-81 years) with lingual or palate gingival region being the most common site (76%). The course of disease was less than 6 months in 92.0% …
The Usefulness of Dermoscopy for the Recognition of Malignant Collision Tumors.
2021
<b><i>Background:</i></b> Preoperative diagnosis of malignant collision tumors (MCT) is extremely difficult. The value of dermoscopy to improve the correct detection of these tumors has not been previously studied. This study aims to evaluate the diagnostic accuracy of MCT with and without dermoscopy and to describe the dermoscopic features of a large series of MCT. <b><i>Methods:</i></b> Dermoscopic images of 161 MCT were evaluated. Clinical and dermoscopic images of histopathologically proven MCT intermingled with other tumors were randomly presented to clinicians with different levels of experience, blinded to the diagnosis and objective of…
A new morphologic classification of the alveolar ridge after distraction osteogenesis in human patients. A 17 years retrospective case series study
2020
Background To perform a morphologic classification based on the results of bone augmentation after a distraction osteogenesis. Material and Methods Thirty-four (34) patients (24 women and 10 men; mean age, 47.1 years (SD=9.5); age range, 23 to 62 years) underwent a total of 42 alveolar ridge distractions before the placement of a total of 89 dental implants. Ridge bone morphology was evaluated as the main ordinal variable. Chi-squared, Kruskal-Wallis and ANOVA one-way test were used. Results Category I (30.95%): consisted of wide alveolar rim and no bone defects Category II (28.57%): wide alveolar rim, lateral bone surface concavity. Category III (23.81%): narrow alveolar rim, lateral bone …
Effect of a web-based positive psychology intervention on prenatal well-being: A case series study
2018
Abstract Background Detrimental effects of women’s negative feelings during pregnancy have been extensively examined and documented, but research on the influence of positive feelings and protective factors on their prenatal mental health is scarce. Evidence from the positive psychology field has shown that practicing some brief positive exercises, called positive psychology interventions, can maximize well-being by increasing positive emotions, engagement, and meaning. Aim The aim of this study is to examine the effect of a positive psychology web-based intervention on indices of women’s prenatal well-being. Methods Specifically, a case series design was adopted, and data from six women ar…
