Short-time effects of spa rehabilitation on pain, mood and quality of life among patients with degenerative or post-surgery musculoskeletal disorders. INTERNATIONAL JOURNAL OF BIOMETEOROLOGY 2023; 67:29-36. [PMID: 36207541 PMCID: PMC9546417 DOI: 10.1007/s00484-022-02381-4] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 04/05/2022] [Revised: 09/21/2022] [Accepted: 10/03/2022] [Indexed: 06/16/2023]
Abstract
Clinical trials have demonstrated traditional spa therapy effects in musculoskeletal disorders (MSDs). This is the first observational study in Italy aimed at evaluating in real-life the short-time effects of spa rehabilitation on pain, mood and quality of life (QoL) among degenerative or post-surgery MSDs patients. Through the involvement of six Italian spa facilities, 160 patients were enrolled; data from 123 patients were finally analysed. Seventy-nine patients (64.3%) accessed the spa for degenerative MSDs, while 44 (35.8%) had a post-surgical condition. All the patients included in the study underwent 12 sessions of water-based exercise (joint exercises, muscle strengthening, gait training, proprioceptive and balance techniques) conducted in thermal or in warm water pools, six sessions per week, for a period of 2 weeks from March 2019 up to October 2019. A group of 45 patients (36.6%) also received traditional thermal therapies, including 12 mud therapy sessions and 12 thermal baths, six times each week, for 2 weeks. Evaluation before and after the treatment included the Numerical Rating Scale (NRS), the Short Form Health Survey (SF-12) and the EuroQol-5D (EQ-5D). The analysis of the scores reported in the questionnaires after the treatment showed a significant improvement in all the scores evaluated. Comparison between patients that performed water-based exercise protocols alone (group A) and patients that in addition to water exercise performed traditional thermal interventions (group B) showed no statistically significant differences in NRSp, NRSa, NRSm, SF-12 PCS, SF-12 MCS and EQ-5D variations; only NRSa value reduction was lower in group B. Sulphate water was found to be associated with a lower reduction of all the scores considered, when compared to the other water types. Patients with degenerative or post-surgery MSDs showed favourable effects on pain, mood and QoL after water exercise training alone or in combination with traditional thermal therapy. Our research provides the first proof that spa rehabilitation can be in real-life conditions an appropriate alternative strategy for post-orthopaedic surgical outcomes recovery. In the future, these results will need to be further investigated.

Abstract
Background: Balance and mobility impairments are frequent in people with multiple sclerosis, partly due to cerebellar dysfunctions. Task-oriented behavioural approaches were previously shown to promote physical function. The possibility exists that cerebellar transcranial direct current stimulation (ctDCS) applied during training, known to increase the excitability of the brain, can boost rehabilitation effects through modulation of cerebellum-brain inhibition. Objective: To test the efficacy of cerebellar ctDCS stimulation combined with motor training on mobility and balance in people with multiple sclerosis. Methods: 16 subjects were randomly assigned to receive real- or sham-ctDCS and task-oriented training daily over two weeks in a double-blind, randomised clinical pilot trial. Functional mobility, balance, walking performance and quality of life were tested before and after treatment and at two-week follow-up. Effects of cerebellar stimulation on psychological and executive functions were also recorded. Results: Walking performance, balance and quality of life improved for both groups at post-treatment assessment which was maintained at 2-weeks follow up. A two-way ANOVA revealed a significant time effect for balance and walking performance. A significant interaction effect of time–treatment (F = 3.12, df = 2,26; p = 0.03) was found for motor aspects of quality of life assessment in patients who received real-ctDCS. Conclusions: Task-oriented training improves balance and mobility in people with multiple sclerosis, but ctDCS does not boost motor training effects.

Post COVID-19 persistent fatigue: a proposal for rehabilitative interventions in the spa setting. INTERNATIONAL JOURNAL OF BIOMETEOROLOGY 2021; 65:2241-2243.

Abstract
With this letter to Editor, we aim at offering our viewpoint on the potential use of the spa resources to contribute to the treatment of persistent COVID-19 sequelae. In particular, our argumentations focus on the comprehensive management of fatigue persisting after the resolution of the acute infection. This sequela seems to be the most frequent disabling outcome, leading to a delay in social reintegration and return to working life.We suggest that spa facilities including multidisciplinary interventions and trained staffs could be an appropriate setting for providing rehabilitative protocols to treat chronic fatigue in post COVID-19 subjects. Spa treatments may improve the physical symptoms of chronic fatigue and modulate the immune imbalance, reducing persisting inflammation. Moreover, in the spa setting, specific respiratory rehabilitation and neuropsychological interventions could be provided. The rehabilitative protocol could also properly address comorbidities.In conclusion, respecting the hygiene and preventive measures, the spa setting could represent the appropriate environment to take care of post-COVID chronic fatigue, offering adequate and multidisciplinary rehabilitation protocols. Further, prospective trials on this topic are needed to fully evaluate the positive impact of a comprehensive rehabilitative treatment in the spa environment for subjects with post-COVID-19 fatigue.

From in vitro research to real life studies: an extensive narrative review of the effects of balneotherapy on human immune response. SPORT SCIENCES FOR HEALTH 2021; 17:817-835.

Abstract
Purpose The biologic mechanisms by which balneotherapy (BT) alleviates symptoms of different diseases are still poorly understood. Recently, preclinical models and clinical trials have been developed to study the effects of BT on the immune system. This review summarizes the currently available evidence regarding the effects of spa therapy on the immune response, to confirm the role of BT in the enhancement of immune system and open interesting research fields. Methods PubMed and Google Scholar were searched from 1997 up to June 2020, with search criteria including terms related to BT and immune system. We selected only in vitro research, randomized controlled trials (RCTs) or clinical trials. Results In vitro studies on human and animal samples have demonstrated that thermal waters exert anti-inflammatory and immunomodulatory effects. In particular, H2S donors seem to counteract the inflammatory processes in psoriatic lesions, arthritic fibroblast-like synoviocytes and chondrocytes, and regulate important factors implicated in osteoarthritis pathogenesis and progression. RCTs and clinical trials revealed, after BT, a reduction in circulating levels of pro-inflammatory molecules, such as TNF-α, IL-1β, and C-reactive protein, and an increase in anti-inflammatory molecules such as the IGF-1 growth factor especially in musculoskeletal diseases. Conclusion Further preclinical studies and RCTs could help to exploit BT in real life for preventive and therapeutic treatments.

Abstract
Recent evidences show that balneotherapy applications can affect the immune system, which has an important role in the containment of Covid-19 infection outcomes. It is interesting to consider if balneotherapy, through medical water baths and mud applications can be a suitable treatment in order to influence human immunity in people who have not acquired the infection and in subjects discharged from hospital after Covid-19 recovery. In particular, balneotherapy seems to improve the immune response efficacy, with an effect mediated by mental stress reduction and a direct action, consisting in the modulation of the abnormal inflammation and the enhancement of the immune system, through changes in both cell-mediated and humoral immunity. The main changes demonstrated on human immunity, after balneotherapy, are linked to an increase in the levels and the activity of cells involved in the immune response such as neutrophils and monocytes and to a reduction of the pro-inflammatory cytokines produced by a dysregulated inflammation. Even if further in vitro researches and clinical trials on this topic should be conducted, at present Spa centres, if hygienically controlled according to WHO and national recommendations, may be considered safe places to attend and useful settings to counteract the outcomes of residual unbalanced immunity after Covid-19 infection.

Abstract
The diagnosis of bland-looking spindle cell lesions of the breast is often challenging because there is a close morphological and immunohistochemical overlap among the different entities. The present review will discuss reactive spindle cell nodule/exuberant scar, nodular fasciitis, inflammatory pseudotumor, myofibroblastoma (classic type), lipomatous myofibroblastoma, palisaded myofibroblastoma, benign fibroblastic spindle cell tumor, spindle cell lipoma, fibroma, leiomyoma, solitary fibrous tumor, myxoma, schwannoma/neurofibroma, desmoid-type fibromatosis, dermatofibrosarcoma protuberans, low-grade fibromatosis-like spindle cell carcinoma, inflammatory myofibroblastic tumor and low-grade myofibroblastic sarcoma arising in the breast parenchyma. The pathologist should be aware of each single lesion to achieve a correct diagnosis to ensure patient a correct prognostic information and therapy. Accordingly representative illustrations and morphological/immunohistochemical diagnostic clues will be provided.

Abstract
Dermatofibrosarcoma protuberans (DFSP) is a soft tissue tumor, usually occurring as a cutaneous lesion localized to the trunk or extremities; although it has a high rate of local recurrence, its metastatic potential is very low and complete surgical excision is frequently curative. Most of the cases reported as “DFSP of the breast” are tumors arising in the subcutaneous tissue infiltrating the underlying breast parenchyma. To the best of our knowledge, only 5 cases of DFSP of the breast have been reported to date. We herein present a rare case of DFSP of the breast parenchyma in a 41-year-old female with emphasis on the diagnostic clues and the differential diagnosis with other benign and malignant spindle cell lesions of the breast.

Abstract
Within the dosimetric characterization of particle beams, laterally-integrated depth-dose-distributions (IDDs) are measured and provided to the treatment planning system (TPS) for beam modeling or used as a benchmark for Monte Carlo (MC) simulations. The purpose of this work is the evaluation, in terms of ion recombination and polarity effect, of the dosimetric correction to be applied to proton and carbon ion curves as a function of linear energy transfer (LET). LET was calculated with a MC code for selected IDDs. Several regions of Bragg peak (BP) curve were investigated. The charge was measured with the plane-parallel BP-ionization chamber mounted in the Peakfinder as a field detector, by delivering a fixed number of particles at the maximum flux. The dose rate dependence was evaluated for different flux levels. The chamber was connected to an electrometer and exposed to un-scanned pencil beams. For each measurement the chamber was supplied with {±400, +200, +100} V. Recombination and polarity correction factors were then calculated as a function of depth and LET in water. Three energies representative of the clinical range were investigated for both particle types. The corrected IDDs (IDD k s) were then compared against MC. Recombination correction factors were LET and energy dependent, ranging from 1.000 to 1.040 (±0.5%) for carbon ions, while nearly negligible for protons. Moreover, no corrections need to be applied due to polarity effect being <0.5% along the whole IDDs for both particle types. IDD k s showed a better agreement than uncorrected curves when compared to MC, with a reduction of the mean absolute variation from 1.2% to 0.9%. The aforementioned correction factors were estimated and applied along the IDDs, showing an improved agreement against MC. Results confirmed that corrections are not negligible for carbon ions, particularly around the BP region.

Abstract
Calcifying aponeurotic fibroma (CAF) is a very rare tumor of the extremities, which can be difficult to diagnose due to its wide cyto-architectural pattern. We herein report the clinicopathologic features of a case of CAF localized on the dorsal face of the foot in a 5-year-old male child, diagnosed by needle core biopsy. Differential diagnostic problems are discussed. The present case emphasizes that the diagnosis of CAF can be confidentially rendered on core needle biopsy if the main morphological components of this tumor are concurrently present; however, before making the diagnosis of CAF, the clinical and radiological context should be considered.

Abstract
In carbon ion therapy treatment planning, the relative biological effectiveness (RBE) is accounted for by optimization of the RBE-weighted dose (biological dose). The RBE calculation methods currently applied clinically in carbon ion therapy are derived from the microdosimetric kinetic model (MKM) in Japan and the local effect model (LEM) in Europe. The input parameters of these models are based on fit to experimental data subjected to uncertainties. We therefore performed a sensitivity study of the MKM input parameters, i.e. the domain radius (r d ), the nucleus radius (R n ) and the parameters of the linear quadratic (LQ) model (α x and β). The study was performed with the FLUKA Monte Carlo code, using spread out Bragg peak (SOBP) scenarios in water and a biological dose distribution in a clinical patient case. Comparisons were done between biological doses estimated applying the MKM with parameters based on HSG cells, and with HSG parameters varied separately by ±{5, 25, 50}%. Comparisons were also done between parameter sets from different cell lines (HSG, V79, CHO and T1), as well as versions of the LEM. Of the parameters, r d had the largest impact on the biological dose distribution, especially on the absolute dose values. Increasing this parameter by 25% decreased the biological dose level at the center of a 3 Gy(RBE) SOBP by 14%. Variations in R n only influenced the biological dose distribution towards the particle range, and variations in α x resulted in minor changes in the biological dose, with an increasing impact towards the particle range. β had the overall smallest influence on the SOBPs, but the impact could become more pronounced if alternative (LET dependent) implementations are used. The resulting percentage change in the SOBPs was generally less than the percentage change in the parameters. The patient case showed similar effects as with the SOBPs in water, and parameter variations had similar impact on the biological dose when using the clinical MKM and the general MKM. The clinical LEM calculated the highest biological doses to both tumor and surrounding healthy tissues, with a median target dose (D 50%) of 40.5 Gy(RBE), while the MKM with HSG and V79 parameters resulted in a D 50% of 34.2 and 36.9 Gy(RBE), respectively. In all, the observed change in biological dose distribution due to parameter variations demonstrates the importance of accurate input parameters when applying the MKM in treatment planning.

Abstract
INTRODUCTION Amyloid goiter is due to the deposition of amyloid in the thyroid, resulting with enlargement of the gland and compressive symptoms. CASE We herein present a case of a 45-year-old male patient who complained of a big swelling in the neck. Ultrasound showed an enlarged thyroid gland with mediastinal involvement. The multinodular appearance was consistent with the diagnosis of multinodular goiter. He had a history of multiple myeloma but no sign of systemic amyloidosis. DISCUSSION Thyroid gland was removed and the histopathological examination revealed a diffuse deposition of amyloid associated with metaplastic lipomatosis of the stroma. CONCLUSIONS The treatment of choice in patients with amyloid goiter is total thyroidectomy to solve compression symptoms.

Abstract
Perineurioma is a relatively rare benign peripheral nerve sheath tumor composed of cells resembling to normal perineurium. Although this tumor may arise in the context of a nerve (intraneural perineurioma), extraneural perineurioma does occur, frequently involving the soft tissues of the lower and upper extremities, trunk and head and neck. Rarely it has also been reported in visceral organs, including gastrointestinal tract. We herein describe the clinicopathologic features of a rare case of a perineurioma presenting as a polypoid lesion of the sigmoid colon, emphasizing the pathologic diagnostic clues.

Abstract
Intestinal-type adenocarcinoma is a rare primary vaginal carcinoma and considerably more uncommon than metastatic lesions which represent the most frequent malignancy at this anatomic site. Among all malignant tumors, colorectal, breast and female genital tract carcinomas have the tendency to metastasize to the vagina. As morphologic and immunohistochemical features of intestinal-type adenocarcinoma occurring primarily in the vagina are not specific, clinical and radiologic information is crucial to exclude a metastatic lesion. Herein we present a rare case of intestinal-type adenocarcinoma from a villous adenoma, presenting as a polypoid mass in the posterior wall of vaginal introitus of 51-year-old menopausal woman. To the best of our knowledge, only 19 cases of intestinal-type adenocarcinoma of the vagina have been reported in the English literature so far. Notably the origin from a previous villous adenoma has been well documented only in a few cases.

Abstract
Kikuchi-Fujmoto disease (KFD), also known as "histiocytic necrotizing lymphadenitis", is a rare lymphadenitis of unknown origin, but with an excellent prognosis. It is more common in Asia, but isolated cases are also reported in America, Africa and Europe. The disease can have an acute or subacute course, usually develops in 1 to 3 weeks, with spontaneous resolution in 1-4 months. The main clinical sign is cervical lymphadenopathy, especially in the posterior cervical triangle with bulky and painful lymph nodes, usually affecting only one side; rare cases of generalized lymphadenopathy can be seen. This common clinical presentation can also be accompanied by nausea, vomiting, weight loss, weakness, headache and arthralgia. An extranodal extension of the disease, including involvement of skin, eye, and bone marrow localizations, has been rarely described. Most patients have leukopenia or neutropenia with a relative leukocytosis. At an ultrasound exploration of the affected lymph nodes, a hypoechoic aspect can be seen, with an external, thick and irregular hyperechoic ring. As there are no specific tests for KFD, the final diagnosis is histologically-based from lymph node excisional biopsy. Histological examination shows paracortical foci of coagulative necrosis containing karyorrhectic debris, which are surrounded by numerous CD68+/myeloperoxidase (MPO)+ histiocytes, CD68+/CD123+ plasmacytoid dendritic cells, and a minority of small- to large-sized CD8+lymphocytes and immunoblasts. Differential diagnosis mainly includes systemic lupus erithematous (SLE)-related lymphadenopathy and large cell lymphoma. The histological absence of neutrophils, plasmacells, as well as hematoxylin bodies, is a feature which argues against the diagnosis of SLE. In addition, the absence of auto-antibodies and anti-nuclear antibodies is useful in ruling out an autoimmune disorder. Early diagnosis of KFD is crucial to prevent the patients undergo extensive investigations related to suspected malignant lymphomas or other diseases.

Abstract
Myxoma is one of the rarest benign primary tumors of the long bones. A case of periosteal myxoma of the diaphysis of tibia with a benign course after 7 years, is reported in a 69-year-old man. Radiographic appearance of the lesion showed ero sion of the cortex of bone and extension into soft tissue, suggesting an initial diag nosis of malignancy. A limited biopsy showing benign myxoid tissue was not con sidered specific for diagnosis of myxoma. Histologic examination of the entire lesion was essential to make definitive diagnosis. Differential diagnosis with benign and malignant bone lesions containing myxoid features is discussed. Int J Surg Pathol 2(4) :333-336, 1995

Abstract
PURPOSE To describe the dosimetric commissioning and quality assurance (QA) of the actively scanned proton and carbon ion beams at the Italian National Center for Oncological Hadrontherapy. METHODS The laterally integrated depth-dose-distributions (IDDs) were acquired with the PTW Peakfinder, a variable depth water column, equipped with two Bragg peak ionization chambers. fluka Monte Carlo code was used to generate the energy libraries, the IDDs in water, and the fragment spectra for carbon beams. EBT3 films were used for spot size measurements, beam position over the scan field, and homogeneity in 2D-fields. Beam monitor calibration was performed in terms of number of particles per monitor unit using both a Farmer-type and an Advanced Markus ionization chamber. The beam position at the isocenter, beam monitor calibration curve, dose constancy in the center of the spread-out-Bragg-peak, dose homogeneity in 2D-fields, beam energy, spot size, and spot position over the scan field are all checked on a daily basis for both protons and carbon ions and on all beam lines. RESULTS The simulated IDDs showed an excellent agreement with the measured experimental curves. The measured full width at half maximum (FWHM) of the pencil beam in air at the isocenter was energy-dependent for both particle species: in particular, for protons, the spot size ranged from 0.7 to 2.2 cm. For carbon ions, two sets of spot size are available: FWHM ranged from 0.4 to 0.8 cm (for the smaller spot size) and from 0.8 to 1.1 cm (for the larger one). The spot position was accurate to within ± 1 mm over the whole 20 × 20 cm(2) scan field; homogeneity in a uniform squared field was within ± 5% for both particle types at any energy. QA results exceeding tolerance levels were rarely found. In the reporting period, the machine downtime was around 6%, of which 4.5% was due to planned maintenance shutdowns. CONCLUSIONS After successful dosimetric beam commissioning, quality assurance measurements performed during a 24-month period show very stable beam characteristics, which are therefore suitable for performing safe and accurate patient treatments.

Abstract
Helium ion beams are expected to be available again in the near future for clinical use. A suitable formalism to obtain relative biological effectiveness (RBE) values for treatment planning (TP) studies is needed. In this work we developed a data-driven RBE parameterization based on published in vitro experimental values. The RBE parameterization has been developed within the framework of the linear-quadratic (LQ) model as a function of the helium linear energy transfer (LET), dose and the tissue specific parameter (α/β)ph of the LQ model for the reference radiation. Analytic expressions are provided, derived from the collected database, describing the RBEα = αHe/αph and Rβ = βHe/βph ratios as a function of LET. Calculated RBE values at 2 Gy photon dose and at 10% survival (RBE10) are compared with the experimental ones. Pearson's correlation coefficients were, respectively, 0.85 and 0.84 confirming the soundness of the introduced approach. Moreover, due to the lack of experimental data at low LET, clonogenic experiments have been performed irradiating A549 cell line with (α/β)ph = 5.4 Gy at the entrance of a 56.4 MeV u(-1)He beam at the Heidelberg Ion Beam Therapy Center. The proposed parameterization reproduces the measured cell survival within the experimental uncertainties. A RBE formula, which depends only on dose, LET and (α/β)ph as input parameters is proposed, allowing a straightforward implementation in a TP system.

Abstract
Staphylococcus aureus is one of the most common mastitis-causing pathogens worldwide. In the last decade, livestock-associated methicillin-resistant S. aureus (LA-MRSA) infections have been described in several species, included the bovines. Hence, this paper investigates the diffusion of MRSA within Italian dairy herds; the strains were further characterized using a DNA microarray, which detects 330 different sequences, including the methicillin-resistance genes mecA and mecC and SCCmec typing. The analysis of overall patterns allows the assignment to Clonal Complexes (CC). Overall 163 S. aureus isolates, collected from quarter milk samples in 61 herds, were tested. MRSA strains were further processed using spa typing. Fifteen strains (9.2%), isolated in 9 herds (14.75%), carried mecA, but none harboured mecC. MRSA detection was significantly associated (P<0.011) with a within-herd prevalence of S. aureus intra-mammary infections (IMI) ≤5%. Ten MRSA strains were assigned to CC398, the remaining ones to CC97 (n=2), CC1 (n=2) or CC8 (n=1). In 3 herds, MRSA and MSSA co-existed: CC97-MRSA with CC398-MSSA, CC1-MRSA with CC8-MSSA and CC398-MRSA with CC126-MSSA. The results of spa typing showed an overall similar profile of the strains belonging to the same CC: t127-CC1, t1730-CC97, t899 in 8 out of 10 CC398. In the remaining 2 isolates a new spa type, t14644, was identified. The single CC8 was a t3092. The SCCmec cassettes were classified as type IV, type V or type IV/V composite. All or most strains harboured the genes encoding the β-lactamase operon and the tetracycline resistance. Streptogramin resistance gene was related to CC398. Enterotoxin and leukocidin genes were carried only by CC1, CC8 and CC97-MRSA. The persistence of MRSA clones characterized by broader host range, in epidemiologically unrelated areas and in dairy herds with low prevalence of S. aureus IMI, might enhance the risk for adaptation to human species.

The natural history of spinal neurofibromatosis: a critical review of clinical and genetic features. Clin Genet 2015; 87:401-10.

Abstract
Spinal neurofibromatosis (SNF) is a related form of neurofibromatosis 1 (NF1), characterized by bilateral neurofibromas (histologically proven) of all spinal roots (and, eventually, of all the major peripheral nerve branches) with or without other manifestations of classical NF1. By rigorous application of these criteria to the 98 SNF cases published, we developed: (i) a cohort of 49 SNF patients (21 males and 28 females; aged 4-74 years]: 9 SNF families (21/49), 1 mixed SNF/NF1 family (1/49) and 27 of 49 sporadic SNF patients (including 5 unpublished patients in this report); and (ii) a group of 49 non-SNF patients including: (a) 32 patients with neurofibromas of multiple but not all spinal roots (MNFSR): 4 mixed SNF/MNFSR families (6/32); (b) 14 patients with NF1 manifestations without spinal neurofibromas, belonging to SNF (8/49) or MNFSR families (6/32); (c) 3 patients with neurofibromas in one spinal root. In addition to reduced incidence of café-au-lait spots (67% in SNF vs 56% in MNFSR), other NF1 manifestations were less frequent in either cohort. Molecular testing showed common NF1 gene abnormalities in both groups. The risk of developing SNF vs NF1 was increased for missense mutations [p = 0.0001; odds ratio (OR) = 6.16; confidence interval (CI) = 3.14-13.11], which were more frequent in SNF vs MNFSR (p = 0.0271).
