Purpose
A thorough understanding of the arthroscopic anatomy is important to recognise pathological conditions. Although some ankle ligaments have been described as intra-articular structures, no ...studies have assessed the full visibility of these structures. The purpose of this study was to assess arthroscopic visibility of medial and lateral ankle collateral ligaments.
Methods
Arthroscopy was performed in 20 fresh frozen ankles. The arthroscope was introduced through the anteromedial portal and the anterior compartment was explored in ankle dorsiflexion without distraction. Intra-articular structures were tagged using a suture-passer introduced percutaneously and they were listed in a table according to the surgeon’s identification. After the arthroscopic procedure, the ankles were dissected to identify the suture-tagged structures.
Results
According to the suture-tagged structures, 100% correlation was found between arthroscopy and dissection. In the anterior compartment, the superior fascicle of the anterior talofibular ligament, the distal fascicle of the anterior tibiofibular ligament and the anterior tibiotalar ligament on the medial side were observed. The deep fascicle of the posterior tibiofibular ligament and the intermalleolar ligament were tagged at the posterior compartment.
Conclusion
Ankle dorsiflexion and non-distraction arthroscopic technique allows full visualisation of the medial and lateral ankle collateral ligaments: the superior fascicle of the anterior talofibular ligament, the distal fascicle of the anterior tibiofibular ligament and the anterior tibiotalar ligament. When using distraction, posterior structures as the deep fascicle of the posterior tibiofibular ligament and the intermalleolar ligament can be observed with anterior arthroscopy.
Purpose
To assess the effectiveness of cadaveric ankle arthroscopy courses in reducing iatrogenic injuries.
Methods
A total of 60 novice surgeons enrolled in a basic cadaveric ankle arthroscopy ...course were divided into two groups. Group A (
n
= 32) was lectured on portal placement and use of the arthroscope, whereas group B (
n
= 28) was in addition lectured on specific portal-related complications. Following the performance of anterior ankle arthroscopy and hindfoot endoscopy, the specimens were dissected and carefully assessed for detection of any iatrogenic injuries.
Results
The rate of injury to the superficial peroneal nerve (SPN) was reduced from 25 to 3.6%, in group A compared with B (
p
= 0.033). Injuries to the peroneus tertius or extensor digitorum longus, the flexor hallucis longus and the tibial nerve or the Achilles tendon were also reduced in group B. Overall, the number of uninjured specimens was 50% (
n
= 30) and higher in group B (57%) than group A (44%). Lesions to the plantaris tendon, the sural nerve or the posterior tibial artery were more common in group B, however, without reaching statistical significance. Overall, 25 (13.9%) anatomic structures were injured in anterior arthroscopy compared to 18 (5%) in hindfoot endoscopy, out of a potential total of 180 and 360, respectively (
p
= 0.001).
Conclusion
Dedicated lectures on portal-related complications have proven useful in reducing the risk of injury to the SPN, the commonest iatrogenic injury encountered in ankle arthroscopy. Hindfoot endoscopy is significantly safer than anterior ankle arthroscopy in terms of injury to anatomical structures.
Purpose
Despite the increased use of ankle dorsiflexion without distraction, no reports have specifically addressed the arthroscopic anatomy of the ankle in this position. The purpose of this study ...was to describe the normal arthroscopic anatomy of the ankle joint, when using the ankle dorsiflexion and the dynamic distraction technique, and to propose an arthroscopic examination system for the anterior ankle compartment.
Methods
Ankle arthroscopy was performed in 20 fresh frozen specimens. Arthroscopic examination was performed with the arthroscope introduced through the anteromedial portal. The anterior compartment was examined in ankle dorsiflexion without distraction. The compartment was examined in four steps: (1) lateral area including the lateral gutter; (2) the central area of the anterior tibial rim; (3) the medial area including the medial gutter; (4) the talar neck. Next, distraction was applied to visualise the anterior compartment again and to examine the central and posterior ankle compartments.
Results
Anatomic intra-articular structures were visualised in all specimens. Four intra-articular fat pads, one anteromedial, two syndesmotic and another posteromedial, were constantly observed. A description of the normal arthroscopic anatomy of the ankle using the ankle dorsiflexion and the dynamic distraction technique is detailed for the anterior, central and posterior compartments.
Conclusion
The ankle arthroscopic procedure without distraction allows constant visualisation of the ATFL’s superior fascicle on the floor of the lateral gutter, the ATiFL’s distal fascicle laterally and the most anterior margin of the deltoid ligament in the medial gutter (anterior tibiotalar ligament). However, ankle distraction is required to observe the central and posterior compartments, but it does not provide optimal visualisation of the anterior ankle compartment structures.

The fight against fake news, mainly spread through Internet, is a major public health issue, even among undergraduate students. This study aims to evaluate the effectiveness of a website promoted by ...the Italian Federation of the Provincial Orders of the Medical Doctors as a first aid communication kit for health topics.
Pre-post study using a web-based survey, conducted in April-May 2019 on Medical students and October-November 2020 on Communication Sciences students at the University of Florence (Italy). Methods. Undergraduate students of both schools were exposed to the use of the "dottoremaeveroche" website. Primary and secondary outcomes measures: the Italian-electronic Health Literacy Scale self-assessment tool was used to examine subjects' electronic Health literacy, and source quality. All responses were rated on a 5-point Likert scale. Changing in perception of abilities were examined using the Wilcoxon test.
The 362 participants felt moderately confident in electronic Health Literacy, with an initial Italian-electronic Health Literacy Scale overall mean score of 3.6±0.7 for medical and 3.2±0.8 for communication students. Medical students had a good idea of how to find helpful sources (3.9±0.8) and communication students felt confident in recognizing their quality (3.5±1.0). In contrast, their confidence in using Web information to make health decisions was low (medical: 2.9±1.1; communication: 2.8±1.1). All items improved significantly after "dottoremaeveroche" use (p<.001), with the overall mean score of Italian-electronic Health Literacy Scale increasing to 4.3±0.6 for medical and 4.1±0.8 for communication students.
Low electronic health literacy levels can affect public health efforts, as seen during the COVID-19 pandemic. The effectiveness of "dottoremaeveroche" among students showed the usefulness of online educational interventions that, if further implemented, could help combat the spread of infodemic.
Background
The COVID-19 infodemic is putting pressure on public health systems to control the pandemic. With the internet and social media playing a key role in emergency communication, digital ...health literacy (DHL) can be considered a determinant of health. This study aims to assess the impact of infodemic on the skills of medical students, for whom low levels of DHL may affect the ability to identify the best available medical evidence.
Methods
A cross-sectional web-based survey was conducted at the University of Florence (Italy) in Apr-May 2019 (pre-pandemic period) and in Nov-Dec 2020 (pandemic period) to investigate DHL skills. Two different cohorts of students, both in their first year of medical school, participated in the survey. The 8-item self-assessment tool (IT-eHEALS) with a 5-point Likert scale was used to examine DHL. The change in perception of ability between the two cohorts was examined using the Wilcoxon test.
Results
A total of 329 students participated in the survey in 2019 (F: 58.1%; mean age 20.6±2.1) and 341 in 2020 (F:61.9%; mean age 19.8±2.0). In 2019, participants' DHL level was moderate with a IT-eHEALS overall mean score (MS) of 28.4±5.8. Students had a good idea of how to find helpful health information (MS 3.9±0.8) and how to use the web for this purpose (MS 3.8±0.9), but they were less confident about the usefulness of the information they received (MS 2.9±1.1). In 2020, the medical students' DHL level deteriorated as the overall MS of IT-eHEALS decreased to 23.4±7.2 (p < 0.01). The scores of the IT-eHEALS items were significantly lower and students indicated that they found it difficult to assess the information they found (MS 2.4±1.1; p < 0.01).
Conclusions
DHL can contrast infodemic, but the latter in turn may have a negative impact on perceived DHL skills if personal knowledge base is not well structured. Training programmes for medical students as future health care providers should be reinforces to guide their practise.
Key messages
Assessing digital health literacy is the first step in directing public efforts towards empowering educational programmes to improve health literacy.
Medical students, as future health professionals, should be able to use the best evidence to help their patients identify healthy beliefs and behaviours to manage in health emergencies.
Adult acquired flatfoot deformity is generally associated with a collapsing medial longitudinal arch and a progressive loss of strength of the posterior tibial tendon (PTT). This condition is ...commonly associated with PTT dysfunction or rupture, which can have an arthritic or a traumatic etiology. Several causes have been proposed to explain the clinical evidence of tendon degeneration observed at the time of surgery including trauma, anatomical, mechanical, inflammatory and ischemic factors.
In this review, we analyzed anatomy, pathophysiology and existing classifications of posterior tibial tendon dysfunction.
Anatomical features, and in particular vascularization, expose PTT to major degenerative disorders until rupture. A literature overview showed that a low blood supply of the gliding part of the tendon is linked to a dysfunction and/or a rupture of the PTT in the region located behind the medial malleolus.
PTT low blood supply causes a dysfunction resulting in an abnormal loading of the foot's medial structures. This may be the reason why PTT dysfunction leads to an acquired flatfoot deformity. Conversely, flatfoot deformity may be a predisposing factor for the onset of PTT dysfunction.
The inadequate knowledge about vaccinations of healthcare workers, including medical doctors, has certainly contributed to the spread of the vaccine hesitancy. Therefore, it is essential to improve ...the level of knowledge of future doctors. The aim of the study is to evaluate the impact of a course about vaccinations on the knowledge of medical students.
Medical students were asked to complete an anonymous questionnaire before and after a seminar on vaccination that they willingly attended. The two questionnaires contained the same 10 questions about vaccines. Only the students who had attended the lecture were allowed to fulfil the post-lecture questionnaires through the learning management system (LMS) called "Moodle". A descriptive statistical analysis of the data collected through the comparative evaluation of the answers before and after the seminar was performed. Mann-Whitney test for two independent samples was used to compare medians score before and after the interventions.
A total of 100 medical students filled the pre-lecture questionnaire and 81 of them completed the post-lecture questionnaire. Knowledge of the students on the indication of the MMR (Measles-Mumps-Rubella) vaccine strongly improved after the seminar. Moreover, the number of students who would recommend vaccination for pertussis and influenza during pregnancy increased significantly by 37% and 19% respectively after the seminar and those aware of the need for Herpes Zoster vaccination over the age of 65 increased by 22%.
For future doctors, a thorough knowledge about vaccinations is increasingly required in order to deal with vaccine hesitancy. Extracurricular seminars about vaccines, provided in the second half of the course of study, can have a highly positive impact.

Background
The struggle against fake medical news, nowadays widely spread by web sources, is a main issue in public health especially in a pandemic period. Even among medical students, there is a ...lack of eHealth literacy (eHL) skills to solve medical problems. The Italian Medical Doctors Federation (FNOMCeO) promoted a Web source as a first-aid communication kit for basic notions in health hot-topics named “dottoremaeveroche” (DMVEC). This study aims to evaluate its effectiveness in improving eHL.
Methods
Between April and November 2019, medical students from the University of Firenze (Italy) joined a cross-sectional web-based survey before and after accessing the DMVEC Web source. The 8-item self-assessment tool (IT-eHEALS) was used to examine subject's eHL, in addition to questions on source's features and its quality. All responses were rated on a 5-points Likert scale. Changing of abilities' perception was assessed using Wilcoxon test.
Results
A total of 329 joined the survey, 42% male, mean age of 20.6±2.1. Participants felt moderately confident in eHL, in fact the initial eHEALS overall mean score was 3.6± 0.7. Students had a good perception on how to find helpful health resources (mean score 3.9±0.8) and how to use the Internet to answer health questions (mean score 3.8±0.9), but their ability in using this information to make health decisions was low (mean score 2.9±1.1). All items improved after the use of DMVEC, with overall mean score of IT-eHEALS increasing to 4.3±0.6 (p < 0.0001). Regarding source's quality, mean score related to transparency of sources, an aspect underestimated at first, increased from 3.5±1.2 to 4.7±0.7 (p < 0.0001).
Conclusions
Low levels of eHL can damage public health efforts, as seen during COVID19 pandemic. DMVEC effectiveness in medical students demonstrated that the scaling up to the general population of online educational interventions, with further implementation, could help in tackling infodemic and fake news spreading.
Key messages
Moderate levels of eHL among medical students could reflect lower levels in general population, highlighting this as critical issue in public health.
Educational programs addressed to Health professionals could be adapted and empowered considering general population as target.
Skeletal diseases, both degenerative and secondary to trauma, infections or tumors, represent an ideal target for regenerative medicine and in the last years, stem cells have been considered as good ...candidates for in vitro and in vivo bone regeneration. To date, several stem cell sources, such as adult mesenchymal stem cells, embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs), have shown significant osteogenic potential.
In this narrative review, we analyze the possible advantages of the use of AFSCs in the treatment of skeletal diseases, especially through the application of tissue engineering and biomaterials.
Among the different sources of stem cells, great attention has been recently devoted to amniotic fluid-derived stem cells (AFSC) characterized by high renewal capacity and ability to differentiate along several different lineages.
Due to these features, AFSCs represent an interesting model for regenerative medicine, also considering their low immunogenicity and the absence of tumor formation after transplantation in nude mice.
To determine whether a combination of high-dose therapy and autologous stem-cell transplantation (ASCT) is superior to conventional-dose consolidation and maintenance chemotherapy as postremission ...therapy in adults with lymphoblastic lymphoma.
One hundred nineteen patients were entered onto this prospective randomized trial from 37 centers. Patients received standard remission induction therapy, and responding patients were randomized either to continue with a conventional consolidation/maintenance protocol (CC) or to receive high-dose therapy and ASCT. In some centers, patients with HLA-identical sibling donors were registered on the trial but proceeded to allogeneic bone marrow transplantation (BMT) without randomization.
Of the 119 patients entered, 111 were assessable for response to induction therapy. The overall response rate was 82% (56% complete response, 26% partial response). Of the 98 patients eligible for randomization, 65 were randomized, 31 to ASCT and 34 to CC. Reasons for failure to randomize included patient refusal (12 patients), early progression or death on induction therapy (eight patients), excessive toxicity of induction regimen (six patients), and elective allogeneic BMT (12 patients). With a median follow-up of 37 months, the actuarial 3-year relapse-free survival rate is 24% for the CC arm and 55% for the ASCT arm (hazards ratio = 0.55 in favor of the ASCT arm; 95% confidence interval CI, 0.29 to 1.04; P =.065). The corresponding figures for overall survival are 45% and 56%, respectively (hazards ratio = 0.87 in favor of the ASCT arm; 95% CI, 0.42 to 1.81; P =.71).
The use of ASCT in adults with lymphoblastic lymphoma in first remission produced a trend for improved relapse-free survival but did not improve overall survival compared with conventional-dose therapy in this small randomized trial.
