V-EMF therapy: A new painless and completely non-invasive treatment for striae gravidarum

BACKGROUND

The appearance of striae gravidarum (SG) during pregnancy is a common problem. The most common SG are abdominal striae, which can cause the greatest sequelae after pregnancy, and in the long term. There are several solutions to prevent and treat these striae, but not all are completely effective, and not without side effects.

AIMS

The aim of this study was to evaluate the effectiveness of a treatment that applies an electromagnetic field under vacuum (V-EMF therapy) on the abdominal SG.

METHODS

A retrospective analysis was conducted on the medical records of 26 women affected by abdominal SG and treated with V-EMF therapy. The results were evaluated using two different 5-point Likert Scales: one administered to the treated subjects to evaluate their satisfaction, and one to the doctors who performed the treatment, to evaluate the improvement of the striae. The presence of side effects, and the effects of sun exposure after treatment were also considered.

RESULTS

Only two treated subjects rated their level of satisfaction with a Score III on the Liker Scale. Everyone else expressed higher levels of satisfaction. Only one doctor rated the improvement of the striae with a Liker scale score of III. All the others reported greater improvements. No discomfort or side effects were noted either during the individual treatment sessions, or at the end of the treatment. The striae showed a newfound ability to tan.

CONCLUSIONS

V-EMF therapy proves to be a valid, safe, and effective treatment modality for SG.

Long-term effects of SARS-CoV-2 infection in patients with and without chemosensory disorders at disease onset: a psychophysical and magnetic resonance imaging exploratory study

A preserved sense of smell and taste allows us to understand many environmental "messages" and results in meaningfully improvements to quality of life. With the COVID-19 pandemic, it became clear how important these senses are for social and nutritional status and catapulted this niche chemosensory research area towards widespread interest. In the current exploratory work, we assessed two groups of post-COVID-19 patients who reported having had (Group 1) or not (Group 2) a smell/taste impairment at the disease onset. The aim was to compare them using validated smell and taste tests as well as with brain magnetic resonance imaging volumetric analysis. Normative data were used for smell scores comparison and a pool of healthy subjects, recruited before the pandemic, served as controls for taste scores. The majority of patients in both groups showed an olfactory impairment, which was more severe in Group 1 (median UPSIT scores: 24.5 Group 1 vs 31.0 Group 2, p = 0.008), particularly among women (p = 0.014). No significant differences emerged comparing taste scores between Group 1 and Group 2, but dysgeusia was only present in Group 1 patients. However, for taste scores, a significant difference was found between Group 1 and controls (p = 0.005). No MRI anatomical abnormalities emerged in any patients while brain volumetric analysis suggested a significant difference among groups for the right caudate nucleus (p = 0.028), although this was not retained following Benjamini-Hochberg correction. This exploratory study could add new information in COVID-19 chemosensory long-lasting impairment and address future investigations on the post-COVID-19 patients' research.

Innovative Non-Surgical Plastic Technique for Saddle Nose Correction: A Study on 97 Patients

Background: Non-surgical rhinoplasty is one of the best choices in mild cases of the saddle nose, and it represents a solution for the aesthetical amelioration of facial deformity; nevertheless, in most critical cases, surgical intervention is still required. This study reports the experience and results of a single facial plastic surgeon (M.G.) using a non-surgical technique for the correction of saddle noses in a large cohort of patients. Methods: This retrospective study assesses all patients injected from January 2017 through October 2023 in private clinics in Milan (Italy), London (UK), and Dubai (UAE). All patients were followed up for 12 months. The harvested adipose tissues were processed with different systems and with or without acoustic wave therapy (AWT). The extracted products have been characterized in terms of cellular yield and cell growth. Ninety-seven patients were injected with adipose-derived products or hyaluronic acid (HA). Patients were followed up for 12 months, and satisfaction data were analyzed. Results: The stem cells obtained from the patients who previously received AWT displayed a statistically higher cell growth ability in comparison with those of the cells derived from patients who did not receive AWT. The evolution of patient satisfaction during the time for each group of treatment was investigated, and cellular treatments show the best maintenance of patient satisfaction over time. Conclusions: Dermgraft and AWT approaches resulted in the highest patient satisfaction for the non-surgical correction of the saddle nose deformity.

Gluteal femoral subcutaneous and dermal adipose tissue in female

BACKGROUND

During the sexual maturation, gluteal femoral adipose tissue is subjected to numerous modifications, not observable in other regions, in particular in women and less in men. Other authors described this region, but they used imaging techniques having lower resolution, than MRI proposed in this study. High resolution imaging techniques might provide important and more detailed information about the anatomy of gluteal femoral region.

METHODS

This study has been performed using 7 T-magnetic resonance imaging and ultrastructural analysis in order to provide accurate description of the subcutaneous adipose tissue and dermis of gluteal femoral region. In this study specimens harvested from cadavers and form living patients have been analyzed.

RESULTS

The results showed the presence of three layers: superficial, middle, and deep, characterized by different organization of fat lobules. High resolution imaging showed the adipose papilla that originates from dermis and protrude in subcutaneous adipose tissue. Adipose papilla is characterized by a peculiar morphology with a basement, a neck and a head and these elements represent the functional subunits of adipose papilla. Moreover, ultrastructural study evidenced the relationship between adipocytes and sweat glands, regulated by lipid vesicles.

CONCLUSIONS

This study provides important information about subcutaneous and dermal fat anatomy of gluteal femoral region, improving the past knowledge, and move toward a better understanding of the cellulite physiopathology.

Histological analysis of the dermal and hypodermal layers of the face and correlation with high-frequency 24 MHz ultrasonography and elastosonography

Knowledge of the structure of the face is of fundamental importance. In fact, the face is treated in many areas of medicine, from dermatology, to maxillofacial surgery, to otorhinolaryngology, to ophthalmology, etc. and anti-aging aesthetic treatments, and those for the resolution of blemishes are on the increase. For ethical reasons it is not possible to take biopsy samples for facial analysis in the aesthetic field. The main aim of this study was to demonstrate that a high-resolution bimodal ultrasound examination, combined with elastosonography, could be a valid tool for pre-treatment morphological evaluation. To achieve this goal, skin samples were taken from the forehead, zygomatic area, nasolabial fold, upper and lower lip from cadavers to histologically characterize their structure. Subsequently, these same areas were evaluated in vivo using conventional B-mode ultrasound with a 24 MHz high-frequency probe, and elastosonography. The data obtained with the different techniques were compared, in order to state that modern ultrasound techniques can provide similar histological information. The analysis showed that the superficial hypodermis presented a different shape and structure in the different areas, with the exception of the areas of the upper and lower lip, which appeared similar. With aging, the forehead and zygomatic area showed a volumetric increase in the superficial hypodermic layer, while the lip showed non-structural changes. The morphology of the nasolabial fold remained unchanged. When it is not possible to perform histological investigations on the face, to understand its characteristics and dynamics, ultrasound with a 24 MHz probe would seem to be the most suitable method, while elastosonography could be a valid method for evaluating the stiffness of the structural components.

Hyper- and Hypopigmentation in a Subject with Fitzpatrick Skin Phototype VI: A New Treatment Option

Background: Laser therapies can cause hyper- and hypopigmentation of the skin. There is little evidence in the literature of effective treatments for these types of problems in Fitzpatrick skin phototypes IV-VI. The main aim of this retrospective study is to evaluate the effects of a new therapy that combines the application of electromagnetic fields and vacuum on a subject with Fitzpatrick skin phototype VI, who presented extensive, laser-induced facial dyschromia. The secondary aim is to test the effectiveness of a free imaging software for assessing skin pigmentation. Methods: The level of improvement after therapy was evaluated, with a 5-point Likert scale, one month after the end of the treatment by the subject and by the doctor who performed the treatment, and by two blinded dermatologists. With the free software, a three-dimensional reconstruction of the treated area and the evaluation of the color distribution were performed. Results: Both the subject and the doctors involved in the study positively evaluated the effects of the treatment. The image analysis highlighted the homogenization of the skin color in the treated area. Conclusions: The combination of electromagnetic fields and vacuum for dyschromia treatments appears promising. The new method of assessing melanin levels resulted particularly efficient.

Vacuum and electromagnetic field in synergy for skin rejuvenation: A retrospective study on 217 patients

BACKGROUND

There are many aesthetic treatments aimed at combating aging. In the most common and frequently used ones there are often side effects, albeit minor ones. However, sometimes it is necessary to use medications before or after treatments.

OBJECTIVES

To evaluate the anti-aging efficacy and application safety of a therapy based on the combination of vacuum and electromagnetic fields (EMFs).

METHODS

A retrospective study was conducted to evaluate the aesthetic effects of the treatment on 217 subjects. Before treatment (T0) and after the last session (T1), skin hydration levels, the amount of sebum present and the pH were measured. The presence of discomfort during the sessions and side effects at T1 was verified. At T1, the levels of satisfaction of the patients and of the doctors who performed the treatment were assessed. At 3 and 6 months of follow-up the aesthetic results were re-evaluated.

RESULTS

For all treated subjects, an evident qualitative improvement was observed in the quality of the skin of the neck and face, with an increase in tone and a reduction in wrinkles. The instrumental tests highlighted a normalization of skin hydration, pH, and sebum values. High levels of satisfaction at T0 and good stability of results up to 6 months of follow-up were reported. No discomfort was referred during the treatment sessions, nor any side effects after the entire treatment.

CONCLUSIONS

The treatment that exploits the synergy between vacuum and EMFs is very promising given the effectiveness and safety of the technique.

Stretch marks: a visible expression of connective's involvement in autism spectrum disorders

In autism spectrum disorders (ASDs) in the pediatric population, skin manifestations are generally attributable to the concomitance of allergic forms or to accidental, self-inflicted or abusive lesions. However, clinical evidence has highlighted the presence of an increasing number of abdominal stretch marks, probably caused by the increase in the number of obesity cases in the pediatric population, in general, and therefore also among children with ASD. Stretch marks are often attributed to obesity, as they have an incidence of more than 50% in obese individuals. In the first part of this article we hypothesized that in addition to obesity there are other factors, such as a structural alteration on the skin in people with ASD, which can contribute/aggravate the phenomenon of stretch marks. Despite the high frequency with which stretch marks are found in children with ASD, this aspect has never been studied, the structure of the skin of children with ASD is not known. Furthermore, it is not known whether this structure is different from that of subjects without ASD. In the second part of the article, we hypothesized the mechanisms of the negative impact of simple abdominal stretch marks on the symptomatic picture of children with ASD. The presence of stretch marks, altered tactile perception, altered sensitivity to clothing fabrics can be a combination that influences development and determines negative consequences in the neurological picture of a child with ASD, as it is already known that the altered sensory perception in children with ASD contributes to the deterioration of social behavior. Furthermore, the presence of stretch marks may play a role in the postural and motor defects of children with ASD.

Multilineage-Differentiating Stress-Enduring Cells (Muse Cells): An Easily Accessible, Pluripotent Stem Cell Niche with Unique and Powerful Properties for Multiple Regenerative Medicine Applications

Cell-based therapy in regenerative medicine is a powerful tool that can be used both to restore various cells lost in a wide range of human disorders and in renewal processes. Stem cells show promise for universal use in clinical medicine, potentially enabling the regeneration of numerous organs and tissues in the human body. This is possible due to their self-renewal, mature cell differentiation, and factors release. To date, pluripotent stem cells seem to be the most promising. Recently, a novel stem cell niche, called multilineage-differentiating stress-enduring (Muse) cells, is emerging. These cells are of particular interest because they are pluripotent and are found in adult human mesenchymal tissues. Thanks to this, they can produce cells representative of all three germ layers. Furthermore, they can be easily harvested from fat and isolated from the mesenchymal stem cells. This makes them very promising, allowing autologous treatments and avoiding the problems of rejection typical of transplants. Muse cells have recently been employed, with encouraging results, in numerous preclinical studies performed to test their efficacy in the treatment of various pathologies. This review aimed to (1) highlight the specific potential of Muse cells and provide a better understanding of this niche and (2) originate the first organized review of already tested applications of Muse cells in regenerative medicine. The obtained results could be useful to extend the possible therapeutic applications of disease healing.

Ten-year follow-up of auditory brainstem implants: From intra-operative electrical auditory brainstem responses to perceptual results

The auditory brainstem implant (ABI) can provide hearing sensation to individuals where the auditory nerve is damaged. However, patient outcomes with the ABI are typically much poorer than those for cochlear implant recipients. A major limitation to ABI outcomes is the number of implanted electrodes that can produce auditory responses to electric stimulation. One of the greatest challenges in ABI surgery is the intraoperative positioning of the electrode paddle, which must fit snugly within the cochlear nucleus complex. While there presently is no optimal procedure for intraoperative electrode positioning, intraoperative assessments may provide useful information regarding viable electrodes that may be included in patients' clinical speech processors. Currently, there is limited knowledge regarding the relationship between intraoperative data and post-operative outcomes. Furthermore, the relationship between initial ABI stimulation with and long-term perceptual outcomes is unknown. In this retrospective study, we reviewed intraoperative electrophysiological data from 24 ABI patients (16 adults and 8 children) obtained with two stimulation approaches that differed in terms of neural recruitment. The interoperative electrophysiological recordings were used to estimate the number of viable electrodes and were compared to the number of activated electrodes at initial clinical fitting. Regardless of the stimulation approach, the intraoperative estimate of viable electrodes greatly overestimated the number of active electrodes in the clinical map. The number of active electrodes was associated with long-term perceptual outcomes. Among patients with 10-year follow-up, at least 11/21 active electrodes were needed to support good word detection and closed-set recognition and 14/21 electrodes to support good open-set word and sentence recognition. Perceptual outcomes were better for children than for adults, despite a lower number of active electrodes.

V-EMF treatment of facial scar: First results

AIM OF STUDY

This is a retrospective study aimed at evaluating the effectiveness of the use of electromagnetic fields and negative pressure treatment (V-EMF) for facial scars, from an aesthetic and functional point of view, and considering the variations in the levels of hydration.

MATERIAL AND METHODS

25 subjects with facial scarring were re-evaluated after being treated with the V-EMF method. The hydration levels of the scars before and after treatment were compared. The results were evaluated considering the satisfaction levels of the patients with the VAS, and of the medical specialists who performed the treatment, and of 3 independent dermatologists with the Likert scale.

RESULTS

Mean hydration levels of scars went from 41.8 to 53.3, with mean hydration levels of healthy reference points equal to 54.6. The minimum patient satisfaction level was 2 in the VAS. The minimum level of satisfaction of specialists and dermatologists was equal to IV on the Likert scale for all patients, except for 1 subject in which it was III for the specialist who had treated him. Anti-aging and re-pigmentation effects were also noted as secondary results.

CONCLUSIONS

From an aesthetic and functional point of view, and for the overall anti-aging effect of the treated area, V-EMF applied to facial scars has shown extremely promising results.

P369 BIOCIRCUIT®: A NEW SYSTEM FOR IMPROVING EXERCISE CAPACITY IN PATIENTS WITH CARDIOVASCULAR DISEASE

Introduction

Cardiovascular diseases is one of the most important public health problems; are among the main causes of morbidity, disability and mortality. Those who survive to an acute form become chronically ill with repercussions on the quality of life and on the economic and social costs. Secondary prevention through an intervention aimed to modify risk factors, in particular the sedentary lifestyle could be effective in the improvement of functional abilities. In this observational study carried out at the ABCardio company in Bologna (Italy), a personalized program of Physical Activity was performed through the innovative Biocircuit technology (Technogym®), on outpatients with a prevalent diagnosis of chronic ischemic heart disease.

Methods

We have analyzed 31 patients (M / F, 25/6) with a mean age of 61 years, and BMI of 26.4 kg / m2. Patients followed a two–month personalized physical activity program consisting in functional assessment at baseline (T0) and at the end of the program (T1) and of 2 weekly training sessions. Evaluation included: lower and upper limb isokinetic test to measure muscle strength, 500–meter moderate walking test to estimate maximum oxygen uptake (VO2max).

Results

The results obtained from the comparison between T0 and T1 in the 31 patients in study show significant improvements in the muscle strength of the lower limbs: Leg press +32.9 kg (p = 0.0003), Leg curl +11.8 kg (p < 0.0001), Leg extension +15.8 kg (p = 0.0002); as well as in upper limb muscle strength: Low Row +10.5 kg (p = 0.0005), Chest press +5.7 kg (p = 0.0007), Shoulder press +6.2 kg (p = 0, 0005). Estimated VO2max was also significantly improved from 26.2 mL / kg / min (T0) to 36.3 mL / kg / min (T1), with a mean increase of 10.1 mL / kg / min (p = 0, 0001). No adverse events occurred during supervised training sessions.

Conclusions

The program, safe and well tolerated by the patients in study, has proved to be effective in increasing exercise capacity in terms of both muscle strength and aerobic capacity. This secondary prevention intervention can be considered useful in reducing residual cardiovascular risk as it induced a significant increase in VO2max.

P370 INNOVATIVE TELEMONITORED MODEL OF PHYSICAL EXERCISE PRESCRIPTION IN SECONDARY PREVENTION DURING THE QUARANTINE

Introduction

COVID–19 pandemic induced the emanation of extraordinary measures like quarantine, that can be considered a risk factor for both physical and mental health in the population. In particular, gym’s closure and the need to stay home didn’t allow people to perform physical activity easily, with a consequent worsening of cardiovascular risk factors. During quarantine some general recommendations have been disseminated, but little is known about specific guidelines for home–based exercise prescription in patients with cardiovascular disease. Therefore, the purpose of this study is to develop home–based physical exercise programs for cardiac patients referred to the Center for Exercise Science and Sports of University of Ferrara.

Methods

On the basis of exercise capacity obtained from the last functional evaluation, performed in presence before the closure, three structured workouts were realized following the guidelines. They are composed as follows: warm–up, strenght and balance exercises alternate to indoor walking, cool–down. Patients received an explicative iconographic via e–mail or smartphone. Some domiciliary sessions were supervised by an operator through video connection.

Results

All patients showed excellent compliance with the proposed program. Adherence has been verified through biweekly recalls. No adverse events occurred.

Conclusions

Telemonitored exercise prescription in cardiac outpatients was effective and safe, helping to prevent negative consequences of the abrupt cessation of physical activity due to COVID–19 pandemic. These evidence could be useful even after the end of pandemic, for all those patients that are less likely to participate in traditional cardiovascular rehabilitation programs because of difficulties in reaching facilities or leaving home.

P401 REMOTE COUNSELING ROLE DURING COVID–19 PANDEMIC IN SECONDARY PREVENTION AFTER ACUTE CORONARY SYNDROME

Introduction

Patients affected by acute coronary syndrome are usually referred to center–based secondary prevention programs where they are enrolled in physical activity programs and received indications about cardiovascular risk factors control. COVID–19 pandemic induced the emanation of restrictions in people’s mobility, ban on gathering and the obligation of social distancing. This made it difficult to maintain such group meetings in presence.

Methods

After hospitalization for acute coronary syndrome in Cardiology Unit of the AUSL of Ferrara, patients equipped with electronic devices were allowed to participate to remote counseling meetings on the digital platform LifesizeC. To improve participation, meetings were organized monthly (in order to gradually include new discharged patients) and involving caregivers (if patients weren’t able to access the web app). Information on regular physical activity benefits were provided. In particular, the F.I.T.T. principle (Frequency, Intensity, Type, Time) has been explained and Borg’s exertion scale was illustrated to be used in autonomy. Furthermore, there were provided recommendations about the need of a proper warm– up/cool–down, the possibility to wear a heart rate monitor and the early recognition of symptoms and warning signs. To complete health education, there were given information about correct nutrition, risk factors control and correct assumption of pharmacological therapy.

Results

All patients showed interest in the topics analyzed, asking various questions during the meetings. They also stated that they were strongly motivated to undertake regular physical activity having received convincing explanations on its usefulness and safety.

Conclusions

Remote counseling meetings obtained a high approval rating and the moments of discussion with the speakers were particularly well attended. The prescription of physical exercise in secondary prevention can follow innovative telemonitored approaches, which could be maintained even after COVID–19.

P422 EARLY EXERCISE PRESCRIPTION AFTER ACUTE CORONARY SINDROME. A NEW MODEL FROM BEDSIDE TO THE COMMUNITY

Purpose

Physical inactivity is a major risk factor and negative prognostic index of cardiovascular disease. It is necessary to define effective strategies to direct patients after an acute coronary syndrome (ACS) to physically active lifestyle. The aim of this study was to examin efficacy, feasibility and long term adherence of a new physical activity prescription, adapted to patients (pts) early after ACS.

Methods

34 pts, mean age 67years, hospitalized for ACS, were enrolled consecutively and randomized 2:1 in treatment (TR) group (n = 23) or in control (CT) group. All pts were evaluated before discharge from hospital (T0) through Quality of Life (QoL) SF12 questionnaire, determination of physical activity during free time, six–minute walking test (6MWT). All pts were orally advised about the importance of changing life–style as recommended by current international guidelines. At T0, pts in the TR group performed a 500m moderate and perceptually–regulated (11–13 on the 6–20 Borg scale) treadmill walking test (500–m TWT) to estimate peak oxygen uptake (VO2peak). A home–based physical activity based on walking, was provided to pts in the TR group: it was recommended to maintain the level of perceived intensity of effort as indicated during 500m–TWT. These pts also received a reinforce phone–call at 2 and 4 weeks (T1 and T2), that allowed monitoring the adherence to the programme. All pts were finally evaluated 8 weeks after enrollment (T3) through the same tests performed at T0.

Results

Pts of the TR group at T3 reported significative improvement, compared to T0, in 6MWT (+79 m, p < 0.001), QoL (expressed in the items of SF12), usual physical activity during free time (+13MET/h/week, p < 0.001), VO2peak (+4 mL/kg/min, p < 0.001). Compliance to the programme resulted optimal since all TR group pts continued the planned physical activity for all the follow–up.

Conclusions

Results of this study on efficacy, feasibility and compliance of a new model of secondary prevention programme, suggest the importance of implementing programmes of tailored physical activity schedules, based on walking, that can be safetly started soon after clinical stabilization of ACS.

P14.72 Involving patients and caregivers in the production of guidelines for palliative care in primary brain tumours: identification of intervention priorities

BACKGROUND

Involving patients and caregivers is an important component of clinical guideline development. The three main Italian scientific associations for neurology, neuro-oncology and palliative care (SIN-AINO-SICP) recently appointed a joint task force (TF) of clinicians and researchers to develop specific guidance on palliative care of people with primary brain tumours, following the GRADE approach. To identify clinical questions meaningful to the patients and caregivers, a qualitative approach was used.

MATERIAL AND METHODS

Based on the existing literature and on consensus, the TF identified nine intervention areas, whose relevance was apprised by patients (via personal semi-structured interviews) and bereaved caregivers (via focus groups, FGs) from five tertiary neuro-oncology centres. Participants were prompted to provide their personal disease-related experience, and were asked to elicit the areas that mostly impacted their own lives. Interviews and FGMs were audio-recorded, transcribed and analysed using thematic analysis.

RESULTS

Twenty interviews and five FGs (28 caregivers) were completed between late 2020 and early 2021. Preliminary findings show that all the pre-specified areas were defined as important by participants. Most discussed topics were communication, organization and service satisfaction, cognitive and psychological issues, and advance care planning (ACP). Caregivers focused their discussions on the need for patient psychological support, difficulties experienced with symptoms control (e.g. epileptic seizures, behavioural changes), communication and organizational issues.

CONCLUSION

Participation of Italian patients with brain tumours and family caregivers was high and information-rich. All of the nine guideline intervention areas were considered important, communication, care organization, symptom control and ACP being the most discussed.

Lipoaspirate processing for the treatment of knee osteoarthritis: a review of clinical evidences

The autologous lipoaspirate processing allows to obtain a tissue product to be transplanted for regenerative purposes in multiple pathological sites, such as the knee joint affected by osteoarthritic disease. Recently, multiple protocols and devices have been designed for lipoaspirate processing. These protocols and devices do not use enzymatic digestion and respect the principles of the so-called "minimal manipulation in a closed system". In this study, we performed a systematic review of the literature to identify studies in which osteoarthritis was treated by minimally manipulated intra-articular SVF injection and assessment of therapeutic response was reported. All bias scores were analyzed based on the Coleman methodology score modified by Kon et al. [27] and a subsequent linear classification system of articles was proposed. We identified 12 clinical trials in which clinical evaluations were performed inconsistently using different scales of analysis. All studies reported a significant decrease in the patient's symptomatic discomfort, with improvement in joint function and reduction in pain. Most studies do not reach a high-quality level on the linear scale based on the Coleman-Kon scores. Although the treatment of osteoarthritis of the knee with regenerative methods is undoubtedly of interest, being aimed at healing the disease, this study highlights that the trials are numerically limited, and qualitatively not optimal according to the Coleman-Kon score. Reasonably, greater standardization of devices protocols will be desirable in the future. The high clinical potential offered by these methods could be optimized for all patients.

Chemosensory Systems in COVID-19: Evolution of Scientific Research

COVID-19 disease induced by coronavirus SARS-CoV-2 presents among its symptoms alterations of the chemosensory functions. In the first studies on the Chinese population, this symptomatology was not particularly relevant, and hyposmia and hypogeusia were excluded from the symptoms to be evaluated to diagnose the disease. With the pandemic spread of the illness, there has been an augment in reports on chemosensory dysfunctions among patients. The first data analysis showed the presence of these disorders mainly in paucisymptomatic and asymptomatic patients. The interest in chemosensory systems therefore increased considerably, because the olfactory and gustatory symptoms could be the key to stop the infection spread. Furthermore, the degree of alert and attention grew, considering that these types of dysfunctions are prognostic symptoms of serious neurodegenerative diseases. About 9 months have passed since the first anecdotal reports on the involvement of the olfactory and gustatory systems in the COVID-19 pathology. For this reason, a careful review of the literature was conducted to understand if it is clearer which people present chemosensory symptoms and if these are related to the severity of the disease. Furthermore, we have identified which aspects still remain to be clarified.

Comparative technical analysis of lipoaspirate mechanical processing devices

Fat grafting is a well-established procedure in reconstructive, aesthetic, and regenerative medicine, in particular due to the presence in the adipose tissue of a high concentration of mesenchymal stem cells. The need to reduce fat processing times, for an immediate clinical use and regulatory restrictions on the degree of manipulation of human tissues, has led to the development of numerous devices for the mechanical, nonenzymatic processing of adipose tissue. The aim of this study is to describe the state of the art of mechanical devices used for fat processing, performing a technical analysis of the currently commercially available devices. This should facilitate the development of new devices that improve therapeutic results.

EAN guideline on palliative care of people with severe, progressive multiple sclerosis

BACKGROUND AND PURPOSE

Patients with severe, progressive multiple sclerosis (MS) have complex physical and psychosocial needs, typically over several years. Few treatment options are available to prevent or delay further clinical worsening in this population. The objective was to develop an evidence-based clinical practice guideline for the palliative care of patients with severe, progressive MS.

METHODS

This guideline was developed using the Grading of Recommendations Assessment, Development and Evaluation methodology. Formulation of the clinical questions was performed in the Patients-Intervention-Comparator-Outcome format, involving patients, carers and healthcare professionals (HPs). No uniform definition of severe MS exists: in this guideline, constant bilateral support required to walk 20 m without resting (Expanded Disability Status Scale score > 6.0) or higher disability is referred to. When evidence was lacking for this population, recommendations were formulated using indirect evidence or good practice statements were devised.

RESULTS

Ten clinical questions were formulated. They encompassed general and specialist palliative care, advance care planning, discussing with HPs the patient's wish to hasten death, symptom management, multidisciplinary rehabilitation, interventions for caregivers and interventions for HPs. A total of 34 recommendations (33 weak, 1 strong) and seven good practice statements were devised.

CONCLUSIONS

The provision of home-based palliative care (either general or specialist) is recommended with weak strength for patients with severe, progressive MS. Further research on the integration of palliative care and MS care is needed. Areas that currently lack evidence of efficacy in this population include advance care planning, the management of symptoms such as fatigue and mood problems, and interventions for caregivers and HPs.

Patient and caregiver involvement in the formulation of guideline questions: findings from the European Academy of Neurology guideline on palliative care of people with severe multiple sclerosis

BACKGROUND AND PURPOSE

Patient and public involvement in clinical practice guideline development is recommended to increase guideline trustworthiness and relevance. The aim was to engage multiple sclerosis (MS) patients and caregivers in the definition of the key questions to be answered in the European Academy of Neurology guideline on palliative care of people with severe MS.

METHODS

A mixed methods approach was used: an international online survey launched by the national MS societies of eight countries, after pilot testing/debriefing on 20 MS patients and 18 caregivers, focus group meetings of Italian and German MS patients and caregivers.

RESULTS

Of 1199 participants, 951 (79%) completed the whole online survey and 934 from seven countries were analysed: 751 (80%) were MS patients (74% women, mean age 46.1) and 183 (20%) were caregivers (36% spouses/partners, 72% women, mean age 47.4). Participants agreed/strongly agreed on inclusion of the nine pre-specified topics (from 89% for 'advance care planning' to 98% for 'multidisciplinary rehabilitation'), and <5% replied 'I prefer not to answer' to any topic. There were 569 free comments: 182 (32%) on the pre-specified topics, 227 (40%) on additional topics (16 guideline-pertinent) and 160 (28%) on outcomes. Five focus group meetings (three of MS patients, two of caregivers, and overall 35 participants) corroborated the survey findings. In addition, they allowed an explanation of the guideline production process and the exploration of patient-important outcomes and of taxing issues.

CONCLUSIONS

Multiple sclerosis patient and caregiver involvement was resource and time intensive, but rewarding. It was the key for the formulation of the 10 guideline questions and for the identification of patient-important outcomes.

Proliferative Activity in Human Urologic Malignancies: A Preliminary Study

Cellular proliferative activity was evaluated by the determination of 3H-thymidine labeling index (LI) in 20 specimens of human urologic malignancies (13 renal cell carcinomas and 7 transitional cell bladder carcinomas). Very low LI values were found in renal cell carcinomas, with a median value of 0.28%. Slightly higher proliferative activities were observed in bladder carcinomas, with a median LI value of 1.96%. No significant correlations were found between proliferative activity and pathologic stage or histologic grading in renal cell carcinomas. Although the number of bladder carcinomas evaluated does not allow any definite conclusion, an increase in LI values was found from in situ to invasive carcinoma and from tumors at stage I to tumors at stage III.

Interobserver Reproducibility of Immunohistochemical Her-2/Neu Assessment in Human Breast Cancer: An Update from INQAT round III

The clinical interest in HER-2/neu is related to trastuzumab, a drug used to treat patients with invasive breast carcinoma overexpressing the HER-2/neu protein. It is very important to correctly identify those patients who may benefit from trastuzumab by accurate assessment of the HER-2/neu status. Of the various methods available, the Dako Herceptest for immunohistochemical assay is considered the most reliable to reach this goal. The aim of this study was to investigate within a group of Italian laboratories the reproducibility of the results of HER-2/neu assessment by means of the Dako scoring system on slides stained with the Herceptest kit. This study was also conceived as the continuation of one of our previous studies, which was similar in its aims but different in the classification criteria adopted. Our results show that, whereas the intra-observer reproducibility was generally satisfactory, the interobserver reproducibility was not. Moreover, our findings confirm that the two extreme classes (0 and 3+) are more easy to identify than the other two and that the Herceptest does not allow to discriminate optimally between scoring classes 2+ and 3+. These findings are relevant in clinical practice where the treatment choice is based on categories defined by this assay, suggesting the need of adopting educational programs and/or new reference materials to improve the assay performance.

A consensus review on the development of palliative care for patients with chronic and progressive neurological disease

BACKGROUND AND PURPOSE

The European Association of Palliative Care Taskforce, in collaboration with the Scientific Panel on Palliative Care in Neurology of the European Federation of Neurological Societies (now the European Academy of Neurology), aimed to undertake a review of the literature to establish an evidence-based consensus for palliative and end of life care for patients with progressive neurological disease, and their families.

METHODS

A search of the literature yielded 942 articles on this area. These were reviewed by two investigators to determine the main areas and the subsections. A draft list of papers supporting the evidence for each area was circulated to the other authors in an iterative process leading to the agreed recommendations.

RESULTS

Overall there is limited evidence to support the recommendations but there is increasing evidence that palliative care and a multidisciplinary approach to care do lead to improved symptoms (Level B) and quality of life of patients and their families (Level C). The main areas in which consensus was found and recommendations could be made are in the early integration of palliative care (Level C), involvement of the wider multidisciplinary team (Level B), communication with patients and families including advance care planning (Level C), symptom management (Level B), end of life care (Level C), carer support and training (Level C), and education for all professionals involved in the care of these patients and families (Good Practice Point).

CONCLUSIONS

The care of patients with progressive neurological disease and their families continues to improve and develop. There is a pressing need for increased collaboration between neurology and palliative care.

Solitary thyroid metastasis from colon cancer: fine-needle aspiration cytology and molecular biology approach

Thyroid gland is one of the most vascularized organs of the body, nevertheless clinical and surgical series report an incidence of secondary malignancies in this gland of only 3%. Colorectal carcinoma metastatic to the thyroid gland is not as uncommon as previously believed, infact the number of cases seems to be increased in recent years due to the more frequent use of fine-needle aspiration cytology (FNAC) guided by ultrasonography. Although kidney, breast and lung metastases to the thyroid are frequent, metastasis from colon cancer is clinically rare with 52 cases reported in the literature in the last 5 decades and three cases described as solitary thyroid metastasis from the colon cancer without any other visceral metastases. To the best of our knowledge, we report the fourth case of solitary, asymptomatic thyroid metastasis from colon cancer without involvement of other organs. We discuss the importance of FNAC to detect metastatazing process as a compulsory step of the diagnostic and therapeutic management algorithm, combined with a molecular biology approach. A review of the last 5 decades literature, to update the number of cases described to date, is also included.

Value of KRAS as prognostic or predictive marker in NSCLC: results from the TAILOR trial

BACKGROUND

The prognostic and predictive role of KRAS mutations in advanced nonsmall-cell lung cancer (NSCLC) is still unclear. TAILOR prospectively assessed the prognostic and predictive value of KRAS mutations in NSCLC patients treated with erlotinib or docetaxel in second line.

PATIENTS AND METHODS

NSCLC patients from 52 Italian hospitals were genotyped for KRAS and EGFR mutational status in two independent laboratories. Wild-type EGFR patients (N = 218) received first-line platinum-based chemotherapy and were randomly allocated at progression to erlotinib or docetaxel. Overall survival (OS) according to KRAS mutational status was the primary end point.

RESULTS

KRAS mutations were present in 23% of TAILOR randomized cases. The presence of a KRAS mutation did not adversely affect progression-free (PFS) or overall (OS) survival [hazard ratio (HR) PFS = 1.01, 95% confidence interval (CI) 0.71-1.41, P = 0.977; OS = 1.24, 95% CI 0.87-1.77, P = 0.233], nor influenced treatment outcome (test for interaction: OS P = 0.965; PFS P = 0.417). Patients randomized to docetaxel treatment experienced longer survival independently from the KRAS mutational status of their tumors (HR: mutated KRAS 0.81, 95% CI 0.45-1.47; wild-type KRAS 0.79, 95% CI 0.57-1.10).

CONCLUSION

In TAILOR, KRAS was neither prognostic nor predictive of benefit for either docetaxel or erlotinib. Docetaxel remains superior independently from KRAS status for second-line treatment in EGFR wild-type advanced NSCLC patients.

T-cell receptor gene rearrangement in Epstein-Barr virus infectious mononucleosis

This report describes the case of a previously healthy young man who presented with fever, pharyngitis, cervical lymphadenopathy, lymphocytosis, and severe thrombocytopenia. Serological tests for Epstein-Barr virus were diagnostic of a primary Epstein-Barr virus infectious mononucleosis but severe thrombocytopenia aroused the suspicion of a lymphoproliferative disease. T-cell receptor gene analysis performed on peripheral and bone marrow blood revealed a T-cell receptor γ-chain rearrangement without the evidence of malignancy using standard histologic and immunophenotype studies. Signs and symptoms of the infectious disease, blood count, and T-cell receptor gene rearrangement resolved with observation without the evidence of emergence of a lymphoproliferative disease. In the contest of a suspected lymphoproliferative disease, molecular results should be integrated with all available data for an appropriate diagnosis.

Self-reported sleep disorders in secondary school students: an epidemiological and risk behavioural analysis

PURPOSE

To estimate the prevalence of self-reported sleep disorders (SD), to examine associations among demographic characteristics and familiar factors with SD, between SD and daytime sleep-related disorders (DD) and between evening habits and SD.

METHODS

An anonymous questionnaire was proposed to 1563 students (aged 14-21 years, mean age 16.5 +/- 1.5; 42.8% males, 57.2% females) attending all classes of two high schools in Verona (North-East of Italy). Data were analyzed by some personal and familial characteristics, by definition of three sleeper groups (non problem, occasional problem or problem-sleepers). Moreover SD were put in relation with DD and with some personal evening attitudes.

RESULTS

The 75.5% of the subjects report at least one SD. Difficulty falling asleep is the most frequent SD. The DD concern 91.2% of the sample. Females are more involved than males in SD and DD. All SD result strongly associated with the referred DD, except for sleepiness. Sport is significantly correlated with a minor prevalence of SD. Smoking and studying appear to be associated with SD.

CONCLUSIONS

Since SD in youth constitute an important Public Health matter with a severe social impact they would be accurately studied to offer youth appropriate counselling given the importance of lifestyle in determining good sleep.

Progress in restoration of hearing with the auditory brainstem implant

Fifty years ago auditory scientists were very skeptical about the potential of new prosthetic approaches that electrically stimulated the auditory nerve, the cochlear nuclei (CN), and the inferior colliculus (IC). In those decades, the basilar membrane was considered to play a fundamental and irreplaceable role as a fine spectrum analyzer in hearing physiology, and therefore it was thought that electrical stimulation of the auditory system would have never produced functionally useful hearing. Over the last 30 years, cochlear implants (CIs) have improved steadily to the point where the average sentence recognition with modern multichannel devices is better than 90% correct. More recently, similar performance has been observed with electric stimulation of the brainstem with auditory brainstem implants (ABIs). However, it is clear that to fully understand hearing and to design the next generation of prosthetic devices we must better understand the ear-brain relationship. Indeed some aspects of hearing do not require the intricate complexities of cochlear physiological responses, while other auditory tasks rely critically on specialized details of cochlear processing. The progress in electrical stimulation of the central auditory system requires us to reconsider the patient selection criteria for different implant devices, in particular to evaluate the possibility of ABIs for etiologies with poor outcomes with CIs. In the present review, the latest outcomes in restoration of hearing with ABI are presented. New guidelines are proposed for device selection for different etiologies and future research is suggested to further refine the process of matching an individual patient to the most appropriate implant device.

A survey of 1000 consecutive epidural catheter placements performed by inexperienced anesthesia trainees

BACKGROUND

Education is the core activity of academic anaesthesia departments. One of the main difficulties appears to be the development of realistic high-quality 'training' practices that are safe for patients. The aim of this study was to determine the incidence of complications occurring after epidural catheter placement by inexperienced anaesthesia trainees and their possible relationship with the experience of the operator.

METHODS

In a period covering 16 months, we performed a survey of 1,000 consecutive epidural placements performed by inexperienced anaesthesia residents under the direction of staff members in Padoa University Hospital, Italy. Neurological and cardiovascular complications as well as side effects were assessed and analyzed in terms of the experience levels of the trainees.

RESULTS

Complications during epidural catheter placement included dural puncture (2.2%), epidural vascular damage (1.7%), and paresthesias (0.9%). Postoperative complications and side effects comprised local bleeding at the catheter insertion point (0.7%), catheter malfunction (0.4%), cardiovascular side effects (2.0%) and persistent postoperative paresthesias not caused by local anaesthetic infusion (1.7%). One patient suffered a transient radiculopathy. The overall incidence of complications was similar for each experience level examined.

CONCLUSION

Epidural catheterization performed under supervision by inexperienced anaesthesia residents is not associated with a significantly greater number of complications than reported in the literature. Moreover, at the early stage of training, we could not demonstrate any correlation between the experience of the operator and the incidence of complications incidence.

Update of ABI Outcomes in Non-tumor Adults

Objective

The traditional indication for auditory brainstem implants (ABIs) is neurofibromatosis type 2 (NF2) in subjects older than 12 years. In our department, the indications for ABIs have been extended to non-tumor children and adults with cochlear or cochlear nerve injuries or malfunctions who would not benefit from a cochlear implant. The results obtained in non-tumor adults are reported in this study.

Methods

In our department, from April 1997 to February 2008, ABIs have been implanted in a total of 114 patients (83 adults and 31 children) for different tumor and non-tumor diseases. 15 patients out of 114 have elsewhere previously had a CI with no sound detection. The retrosigmoid-transmeatal approach was used in all tumor patients and the retrosigmoid approach was used in all non-tumor patients.

Results

All patients had a functioning implantation, and reported auditory sensations with activation of various numbers of electrodes. At 1 year after implantations, non-tumor adults scored from 10% to 100% in open set speech perception tests (average 57%), and tumor patients scored from 5% to 30% (average 11%). The difference between these results is statistically significant (p < 0.01).

Conclusions

Hearing outcomes are better in non-tumor than tumor patients, with a significant number of non-tumor patients that are able to understand speech at a level comparable to that of the most successful cochlear implant users, including conversational telephone use.

Subarachnoid anesthesia for loco-regional antiblastic perfusion with circulatory block (stop-flow perfusion)

AIM

Loco-regional antiblastic perfusion with circulatory block (stop-flow perfusion, SFP) is a procedure designed to treat solid tumors of the limb and pelvis in an advanced stage, like melanoma, sarcoma of the soft tissues and colon-rectal cancer. The aim of this study was to evaluate if subarachnoid anesthesia could represent a safe and suitable anesthetic technique for this procedure.

METHODS

Thirty SFP procedures were performed in the angiographic room, 15 for the treatment of lower-limb neoplasias and 15 for pelvic neoplasias. The patients (ASA I-III) had a mean age of 59.1 years (range: 19-81 years). The patients were given different dosages of bupivacaine (range: 10-20 mg) in hyperbaric solution at the concentration of 0.5% and 1% by lumbar subarachnoid injection at different levels (from T12-L1 to L3-L4). Standard monitoring was set up (ECG, pulse-oximetry, and non-invasive artery pressure). The use of any anesthetic and analgesic drug, eventually used in the intra- or postoperative period, was recorded.

RESULTS

The lumbar puncture was approached at L1-L2 and L2-L3 levels in 80% of the cases. Doses of bupivacaine between 12 mg and 14 mg were administered in 2/3 of the cases. Bupivacaine was formulated in hyperbaric solution and administered at a concentration of 0.5% (8 patients) or 1% (22 patients). Complica-tions related to the anesthetic technique were absent. Intraoperative pain control was almost complete with one exception, when the procedure lasted unusually long. Pain control was satisfying immediately after the procedure as well: only in 3 cases were non-opiod analgesics administered within the first 6 h.

CONCLUSIONS

Spinal subarachnoid anesthesia has proven to be an effective, safe, and easy-to-manage technique for carrying out SFP procedure in a non-conventional environment such as an angiographic room. It was free of serious side effects and well tolerated even in patients in poor general conditions.

Successful CD34+ cell mobilization by intermediate-dose Ara-C in chronic lymphocytic leukemia patients treated with sequential fludarabine and Campath-1H

Chronic lymphocytic leukemia (CLL) cells could be undetectable by flow cytometry or polymerase chain reaction after sequential treatment with fludarabine and Campath-1H. Concern has been raised regarding the ability to mobilize sufficient peripheral blood progenitor cells (PBPCs) for autografting after purine analogues, and there are few data about PBPC collection after Campath-1H. In all, 16 CLL patients responding to sequential chemo-immunotherapy entered the study. In 10, mobilization regimen consisted of granulocyte colony-stimulating factor (G-CSF) 5-10 microg/kg/die. Patients failing mobilization or not achieving the target of 2.5 x 10(6) CD34+ cells/kg underwent a second attempt using intermediate-dose (ID) Ara-C, 800 mg/m(2) every 12 h for six doses+G-CSF. PBPC collection after G-CSF alone was successful in two out of 10 patients. An adequate number of CD34+ cells were collected after ID Ara-C+G-CSF in eight patients failing the mobilization with G-CSF alone and in five out of six who did not receive G-CSF before. Greater yields of PBPCs were collected with Ara-C+G-CSF compared with G-CSF alone (13.8 vs 3.3). The extrahematologic toxicity was manageable. In conclusion, PBPC collection is feasible in CLL patients treated with sequential therapy including fludarabine and Campath-1H. Excellent yields were obtained in 92.8% of patients primed with ID Ara-C+G-CSF.
