A meta-analysis of the effectiveness of mud-bath therapy on knee osteoarthritis.

OBJECTIVE: Osteoarthritis (OA) results from loss of cartilage in-tegrity in association with changes to the structure of the entire joint. Treatment of OA is based on different pharmaceutical and no phar-maceutical approaches and the latter include the use of spa-therapy. The biological effects of mud-bath therapy are mainly secondary to heat stimulation and to physic-chemical properties of mineral waters and mud-packs. Mud-bath therapy likely exerts its effects modulating several cytokines and other molecules involved in inflammation and cartilage degradation. Our aim was to perform an updated meta-analysis of the effectiveness of the mud-bath therapy on knee osteoarthritis and briefly to discuss the mechanisms of action of this treatment. MATERIALS AND METHODS: A MEDLINE on PubMed for articles on knee OA and spa therapy published from 1995 through up to April 2019 was performed. Then, we checked the Cochrane Central Register of Controlled Trials to find additional references included up to April 2019. Articles were included if in accordance with the eligibility cri-teria. Sample size and effect sizes were processed with the MedCalc software package. RESULTS: Twenty one studies met the inclusion criteria and were included in meta-analysis. We examined WOMAC Index and VAS pain. We found significant improvements in function scores and painful symptoms after mud-bath therapy in patients with knee joint osteoarthritis. CONCLUSIONS: Spa therapy is a non-drug treatment modalities, non invasive, complication-free, and cost-effective alternative modality for the conservative treatment of knee osteoarthritis. It cannot substitute for conventional therapy but can integrated or alternated to it. Treatment with mud-bath therapy may relieve pain, stiffness and improve functio-nal status in patients with knee OA.

Impaired bone matrix glycoprotein pattern is associated with increased cardio-metabolic risk profile in patients with type 2 diabetes mellitus.

PURPOSE: Osteopontin (OPN), osteoprotegerin (OPG) and osteocalcin (OC) are matrix glycoproteins which mediate bone mineralization; moreover, their effects on glucose/insulin homeostasis have recently been demonstrated. Higher circulating OPN and OPG levels have been associated with the presence of insulin resistance, atherosclerosis and coronary heart disease. No data are available on contextual changes of these markers in type 2 diabetes mellitus (T2DM). Therefore, aims of this study were to evaluate serum OPN, OPG and OC levels in T2DM patients and their clinical correlates. METHODS: We recruited 83 consecutive T2DM patients referring to our diabetes outpatient clinics at Sapienza, University of Rome, and 71 non-diabetic sex and age-comparable subjects as a control group. Study population underwent metabolic characterization and carotid ultrasound for intima-media thickness measurement. Plasma OPN, OPG and OC were measured by MILLIPLEX Multiplex Assays Luminex. RESULTS: T2DM patients had significantly higher circulating OPN and OPG levels than controls (14.3 ± 13.6 vs 10.6 ± 13.7 ng/ml p < 0.001, 0.70 ± 0.60 vs 0.54 ± 4.1 ng/ml, p = 0.02) while OC levels were similar in the two cohorts (6.35 ± 5.8 vs 7.80 ± 7.0 ng/ml, p = n.s). OPN and OPG positively correlated with greater systolic blood pressure (SBP) values, HOMA-IR and HOMA-ß, and with the presence of dyslipidemia and carotid atherosclerosis. The association between greater OPN and OPG levels and SBP was independent from possible confounders (both p = 0.01). CONCLUSIONS: Circulating OPN and OPG levels are increased in T2DM patients and identify a particularly unfavourable metabolic profile, mostly expressed by higher SBP. Bone peptides may represent novel markers of vascular stress and accelerated atherosclerosis in diabetes, constituting a possible tool for cardiovascular risk stratification in diabetes.

Measuring and benchmarking the quality of two different organizational ways in delivering infant vaccination.

The aim of this study was the quality of service evaluation of two different organizational ways in delivering infant vaccination according to a Regional Vaccination Plan. Eleven vaccination centres were selected in two Local Health Units (ASLs) belonging to the Regional Health Service of the Lazio Region, Italy. The services offering paediatric vaccinations for children under three years of age, delivered without an appointment (VACP) or with the need for an appointment (VACL), were investigated. The quality aspects under evaluation were communicational efficiency, organisational efficiency and comfort. Subjective data were collected from different stakeholders and involve the elicitation of best and worst feasible performance conditions for the ASLs when delivering VACP/VACL services. Objective data consists in the observation of current performances of the selected vaccination centres. Quality scorecards were obtained from the combination of all data. Benchmarking between VACP and VACL, i.e., two different organisational ways in delivering infant vaccination, can be performed as a result of the probabilistic meaning of the evaluated scores. An expert of vaccination services, i.e., a virtual combination of patients, doctors and nurses, claims the quality of service delivery of the ASLs under investigation with probability 78.03% and 69.67% for VACP and VACL, respectively. In other words, for short, the quality scores of the ASLs were 78.03% for VACP and 69.67% for VACL. Furthermore our results show how to practically improve the current service delivery. The QuaVaTAR approach can result in improvements of the quality of the ASLs for the two different ways of delivering paediatric vaccinations in a simple and intuitive way.

Increased circulating osteopontin levels in adult patients with type 1 diabetes mellitus and association with dysmetabolic profile.

OBJECTIVE: Osteopontin (OPN) is a sialoprotein implicated in different immunity and metabolic pathways. Capable of activating dendritic cells and inducing Th1-Th17-mediated tissue damage, OPN plays a significant role in the development/progression of several autoimmune diseases; interestingly, it was also shown that OPN participates in the acute pancreatic islets response to experimentally induced diabetes in non-obese diabetic (NOD) mice. Furthermore, OPN promotes adipose tissue dysfunction, systemic inflammation and insulin resistance. Our aims of this study were to evaluate circulating OPN levels in adult patients with type 1 diabetes mellitus (T1DM) compared to non-diabetic control participants and to unravel clinical and biochemical correlates of OPN concentration. DESIGN: Case-control study. METHODS: We enrolled 54 consecutive T1DM patients referred to our diabetes outpatient clinic at Sapienza University of Rome and 52 healthy sex and age-comparable controls. The study population underwent clinical evaluation, blood sampling for biochemistry and complete screening for diabetes complications. Serum OPN levels were measured by MILLIPLEX Multiplex Assays Luminex. RESULTS: T1DM patients had significantly higher serum OPN levels than controls (17.2±12.9 vs 10.5±11.6 mg/ml, P=0.009). OPN levels correlated with T1DM, higher blood pressure, BMI, creatinine, γ-GT, ALP and lower HDL; the association between high OPN levels and T1DM was independent from all confounders. No correlation was shown between OPN and HbA1c, C-peptide, insulin requirement, co-medications and diabetes duration. CONCLUSIONS: This study demonstrates for the first time in a case-control study that adults with T1DM have increased serum OPN levels, and that higher OPN concentrations are associated with an unfavorable metabolic profile in these patients.

Prevention and treatment of nephrolithiasis: a review on the role of spa therapy.

The prevalence and incidence of nephrolithiasis is reported to be increasing across the world. It is a disease of increased urinary concentration of stone-forming salts. The physicochemical mechanism of stone formation includes precipitation, homogenous/heterogeneous nucleation, growth, aggregation and concretion of various modulators in urine. Necessary condition to develop stones is urinary supersaturation, due to reduced urinary volume or to an excesses solutes. Fluid intake is the main determinant of urine volume. Urine dilution can significantly decrease both the crystallization rate of the urinary salts and the aggregation of the crystals. A correct fluid intake can act on different effects: urinary tract washing, urinary volume increasing and dilution of solutes. In addition mineral waters have other particular features: greater diuretic effect, more important urinary dilution with solutes and microbial concentration reduction, urinary pH changes, superior washout effect due to mechanical effects and ureteral contractions. Adequate water intake is the most important conservative strategy in urolithiasis prevention; particularly hydropinotherapy with oligomineral water should be considered as an important instrument to prevent stones in subjects predisposed to the disease (family members of people suffering from kidney stones), to reduce relapses, and can help to eliminate residual fragments also after extracorporeal shock wave lithotripsy. It is recommended a management with increased mineral water intake to promote urine volume of at least 2.5L each day to prevent stone formation. Obviously water intake shall be varied in relation to the presence of contraindications or any diseases.

[Ethics in clinical practice and in health care]. / L'etica nella pratica clinica e nell'assistenza sanitaria.

The clinical ethics is the identification, analysis and solution of moral problems that can arise during the care of a patient. Given that when dealing with ethical issues in health care some risks will be encountered (talking about ethics in general, or as a problem overlapped with others in this area, or by delegation to legislative determinations) in the text certain important aspects of the topic are examined. First of all ethics as human quality of the relationship between people for the common good, especially in health services where there are serious problems like the life and the health. It is also necessary a "humanizing relationship" between those who work in these services in order to achieve quality and efficiency in this business. It is important a proper training of health professionals, especially doctors, so that they can identify the real needs and means of intervention. It is also important that scientific research must respect fundamental ethical assumptions. In conclusion, ethics in health care is not a simple matter of "cookbook" rules, but involves the responsibility and consciousness of individual operators.

TSH levels are associated with vitamin D status and seasonality in an adult population of euthyroid adults.

A circannual periodicity in thyrotropin (TSH) secretion has been reported but the causes of these phenomenon are still undefined. Vitamin D exerts a direct influence on pituitary axes including the hypothalamus-pituitary-thyroid axis. Aims of the present study were to investigate the presence of a seasonal variability of TSH secretion and to study the association between vitamin D status and TSH levels in a population of euthyroid adults. For this purpose, we recruited 294 euthyroid adults (M/F 133/161, 48.5 ± 12.4 years). Study participants underwent clinical examination and routine biochemistry assessment. Vitamin D deficiency was diagnosed for serum 25(OH) vitamin D <25 nmol/l. Significantly higher TSH levels were found in subjects who underwent blood sampling during the Autumn-Winter compared with individuals evaluated in Spring-Summer (2.3 ± 1.3 vs. 1.8 ± 1.1 µIU/ml, p = 0.03). Vitamin D deficiency was strongly associated with higher TSH levels (p = 0.01) after adjusting for sex, age, and sample's season. Although vitamin D deficiency was also associated with metabolic syndrome and its components, the association between TSH levels and vitamin D status persisted also considering these confounders. These data reveal the occurrence of seasonal variability of serum TSH concentration in euthyroid subjects and provide evidence for the first time that an association exists between vitamin D status and serum TSH levels.

The therapeutic activity of sulphate-bicarbonate-calcium-magnesiac mineral water in the functional disorders of the biliary tract.

BACKGROUND AND AIM: Functional disorders of the biliary tract involve gallbladder and sphincter of Oddi and cause pain and/or digestive troubles. In this context, in addition to pharmacological treatments, an important role is played by the use of sodium-sulphate and sulphate-bicarbonate mineral waters that, because of their composition into ions macro and trace elements, can stimulate the release or modulate the activity of some neurohumoral regulators of the digestive process. We want to do a study on the effects of hydropinotherapy with a sulphate-bicarbonate-calcium-magnesium mineral water in patients suffering from pain and other symptoms caused by biliary dyskinesias, biliary sand (without gallstones), or following a cholecystectomy (post-cholecystectomy syndromes). MATERIALS AND METHODS: We enrolled 43 patients suffering from those affections; all the patients did two cycles in one year of hydropinotherapy with Acqua Santa at Italy's Chianciano Spa; 20 of these patients did a third cycle of hydropinotherapy in the second year of the study. At the end of the second and of the third cycle we compared the frequency of eleven main symptoms in both groups and we also performed an longitudinal-observational study on the frequency of those symptoms before the beginning of the first cycle of the therapy and at the end of the second and of the third cycle. Statistical analyses were based on the use of Pearson's χ2 test. RESULTS: The frequency of the symptoms observed at the end of second and third cicle of hydropinotherapy was significantly lower than that considered before starting therapy. The differences were statistically significant. CONCLUSIONS: The results of our research regarding the hydropinotherapy by sulphate-bicarbonate-calcium-magnesium mineral water show a significant improvement of symptoms in patients suffering from disturbances of biliary tract.

[The possible uses of balneotherapy in treating chronic venous insufficiency of lower limbs]. / Possibilità della balneoterapia termale nell'insufficienza venosa cronica degli arti inferiori.

The Chronic Venous Insufficiency (CVI) of inferior limbs is a widespread disease, with an increasing incidence as a consequence of longer life expectance, life-style, obesity, smoking, use of drugs as oestrogens and progestins and working conditions. Medical therapy is still lacking for evidence of efficacy, and compression therapy is useful only in preventing a worsening of this condition. Surgical treatment is the only radical therapy effective for the advanced phases of the disease. In this context spa balneotherapy can be considered as a possible chance to improve some subjective and objective symptoms of CVI of inferior limbs, and to prevent worsening of this condition. The authors performed a review of the relevant scientific literature concerning the treatment of CVI of inferior limbs with mineral water balneotherapy, in order to evaluate its effects on objective and subjective symptoms and its effectiveness to prevent further worsening. We searched the PubMed/Medline, Cochrane Library, Embase, Web of Science databases for articles published between 1990 and 2011 on this topic. To this end, the authors selected few clinical-controlled and case-controlled studies; patients affected from CVI of inferior limbs were treated with balneotherapy at health spas with sulphureous, sulphate, salsojodic or salsobromojodic mineral waters. Baths in mineral waters were often associated with idromassotherapy and vascular pathway. Effects of spa balneotherapy are related to some aspecific properties, like hydrostatic pressure, osmotic pressure and water temperature, partly related with specific chemico-physical properties of the adopted mineral water. The controlled clinical studies on spa therapy showed significant improvement of subjective (such as itch, paresthesias, pain, heaviness) and objective symptoms (namely edema and skin discromias). These studies suggest that spa balneotherapy may give a good chance of secondary prevention and effective therapy of CVI of inferior limbs, but also that it needs of other clinical controlled trials.

Changes, functional disorders, and diseases in the gastrointestinal tract of elderly.

This article describes changes in the basic digestive functions (motility, secretion, intraluminal digestion, absorption) that occur during aging. Elderly individuals frequently have oropharyngeal muscle dysmotility and altered swallowing of food. Reductions in esophageal peristalsis and lower esophageal sphincter (LES) pressures are also more common in the aged and may cause gastroesophageal reflux. Gastric motility and emptying and small bowel motility are generally normal in elderly subjects, although delayed motility and gastric emptying have been reported in some cases. The propulsive motility of the colon is also decreased, and this alteration is associated with neurological and endocrine-paracrine changes in the colonic wall. Decreased gastric secretions (acid, pepsin) and impairment of the mucous-bicarbonate barrier are frequently described in the elderly and may lead to gastric ulcer. Exocrine pancreatic secretion is often decreased, as is the bile salt content of bile. These changes represent the underlying mechanisms of symptomatic gastrointestinal dysfunctions in the elderly, such as dysphagia, gastroesophageal reflux disease, primary dyspepsia, irritable bowel syndrome, primary constipation, maldigestion, and reduced absorption of nutrients. Therapeutic management of these conditions is also described. The authors also review the gastrointestinal diseases that are more common in the elderly, such as atrophic gastritis, gastric ulcer, colon diverticulosis, malignant tumors, gallstones, chronic hepatitis, liver cirrhosis, Hepato Cellular Carcinoma (HCC), and chronic pancreatitis.

[SPA treatments of diseases pertaining to internal medicine]. / I mezzi di cura termale nella terapia di malattie di competenza internistica.

Authors resume the therapeutic employment of mineral waters, muds and baths in internistic syndromes or diseases. Mineral waters are used in the therapy of functional dyspepsia, gastro-oesophageal reflux, chronic primary stipsis, irritable bowel, biliary dyskinesias, mainly hypokinetic gallbladder and Oddi's sphincter, spasm, postcolecystectomy syndrome. The therapeutic effects of mineral waters are determined by their anion and cation content, the presence of undissociated salts and also by the presence of oligoelements. Additionally, the effects of a mineral waters are connected with physical constants: osmotic pressure and temperature. Many researches showed activity of the mineral waters on intestinal autonomic nerves and plexus (CIA), motility, exocrine, endocrine and paracrine digestive secretions and therapeutic properties belonging to evidence based medicine. Mud and bath therapy are effective in treatment of osteoarthritis. During and after mud-therapy effects on diencephalic-pituitary-adrenal axis were displayed, producing increase of endogenous opioids and cortisol. Clinical controlled trials showed significant improvement of symptoms as pain and stiffness. Inhalant therapy by sulphureous and salsojodic mineral waters improve symptoms as cough and escreate and functional indices as FEV1 in chronic obstructive pulmonary disease. The oligomineral waters are very useful in the treatment and secondary prevention of urolithiasis and of relapses of urinary stones after spontaneous expulsion, surgical treatment, stones removal by percutaneous or uretheroendoscopic treatment and lithotrypsia. Patients must drink at least 2L every day, substantially for ever. Chloruratesodic and bicarbonate mineral waters show improvement in disorders of lipidic and urate metabolism.

Sulphate-bicarbonate mineral waters in the treatment of biliary and digestive tract diseases.

The authors point out the therapeutic properties of sulphate-bicarbonate mineral waters. After summarizing the general mechanism of action of mineral waters, the main indications of such waters in thermal treatment are examined including: biliary sand, biliary dyskinesia, functional dyspepsia, irritable colon, chronic primitive constipation. The dysfunctions of biliary and digestive tracts are growing, mainly in the affluent world, because of the increase for stress, dietary habits, modern life style. Now they affect from 2,4% of general population to 7% of men and 20% of women, according to different studies. Mineral waters can improve symptoms and care some physiopathological underlying mechanisms. Authors stress the efficacy of sulphate-bicarbonate mineral waters in the therapy of biliary dyskinesias, namely gallbladder hypokinesia and Oddi's sphincter spasm, caused by their content in SO4 = anion and Mg++ cation and related effects on paracrine-endocrine gastrointestinal system. In addition, they report the effects of sulphate-bicarbonate mineral waters in the lithogenic bile (sand bile), because of their diluting and washing activity. Among the sulphate-bicarbonate mineral waters, the Authors outline the well-documented therapeutic activity of Acqua Santa and Fucoli of Chianciano Terme. Acqua Santa has stimulating effect on cholecystis's motility, as proved by controlled clinical trials. Finally, the therapeutic use of sulphate-bicarbonate mineral water is discussed in functional dyspepsia, chronic primitive constipation and irritable bowel syndrome.

Subclinical vascular alterations in young adults with type 1 diabetes detected by arterial tonometry.

BACKGROUND: Diabetes mellitus is characterized by a very high prevalence of atherosclerotic disease. Aims of this study were to determine arterial compliance parameters in type 1 diabetes (T1D) patients as an expression of early pre-clinical endothelial dysfunction and to evaluate the impact of glucose exposure parameters such as the duration of diabetes and glycosylated haemoglobin (HbA(1c)) on the risk of developing alterations in vascular compliance. METHODS: 23 patients with uncomplicated type 1 diabetes (mean age: 32.78 +/- 9.06 years, mean disease duration: 10.78 +/- 7.51 years, mean HbA(1c) levels: 7.7 +/- 1.9) and 26 age- and sex-matched healthy subjects (mean age: 32.3 +/- 8.51 years) were recruited. In these subjects, we evaluated arterial compliance by calibrated tonometry (HDI/Pulsewave() CR-2000). Parameters included the following: large artery elasticity (C1), small artery elasticity (C2), systemic vascular resistance (SVR) and total vascular impedance (TVI). RESULTS: Patients with longer duration of T1D (>10 years) showed significant alterations in C2 (4.97 +/- 2.7 mL/mmHg x 100) and in SVR (1464.67 +/- 169.16 dina x s x cm(-5)) when compared with both healthy individuals (C2: 8.28 +/- 2.67 mL/mmHg x 100, p = 0.001; SVR: 1180.58 +/- 151.55 dina x s x cm(-5), p = 0.01) and patients with recent-onset disease (

[Spa therapy in osteoarthritis: experience in Cervia]. / La terapia termale nell'osteoartrosi: esperienza di Cervia.

AIMS: Mud-bath treatment has a relevant therapeutic activity in reducing symptoms and disabilities in rheumatic diseases, as studies on inflammation process and clinical symptomatology have shown. Objective of this study is to evaluate the efficacy of mud therapy by natural limans of Cervia on clinical parameters in patients with lumbar spine osteoarthrosis (OA). MATERIALS AND METHODS: 30 patients (20 females and 10 males) suffering from lumbar OA, diagnosed by clinical symptoms and X-Ray findings (osteophytosis, morphological changes of vertrebral somes, tightness of intervertebral spaces, alterated lumbar physiologic lordosis) were studied. All patients were examined first when recruited (T0) and after two weeks of therapy (T1). Interviews were submitted in order to estimate functional restrictions and pain. Statistical analysis was performed via t test for paired data. RESULTS: On the basis of the statistical analysis a very significant difference was demonstrated between the average values of the tests before and after the treatment. These results confirm the improvement of the symptoms concerning the pain, the articular functionality and the quality of life. CONCLUSIONS: The results of the study demonstrate the efficacy of the mud-bath treatment with natural limans of Cervia on the patients affected by lumbar spine osteoarthrosis (OA).

[Efficacy of mud-bath therapy with Mineral Water from the Sillene spring at Italy's Chianciano Spa for osteoarthritis of the knee: a clinical statistical study]. / Effcacia della fangobalneoterapia con Acqua Minerale Sillene (Terme di Chianciano, Italia) nell'osteoartrosi del ginocchio: uno studio clinico-statistico.

AIMS: Many previous researches showed clinical benefits, effects on inflammatory mediators and pain, immune system, hormones and on the diencephalic-pituitary-adrenal axis. Our study evalues the efficacy of mud-bath therapy with mineral water from the Sillene Spring at Italy's Chianciano Spa in patients with osteoarthritis of the knee. MATERIALS AND METHODS: In study we compared: physical examination of the knee joint, visual analogue scale (VAS) assessment of pain, and Lequesne Algo-functional Index. Tests were performed in 61 patients divided into 2 groups. The group A underwent three full cycles of mud-bath therapy over 1 year's time, the group B did not. An observational longitudinal study was also conducted on the patients of group A, before and after completion of the treatment protocol. Statistical analyses were based on use of Pearson's chi² test, Student's t tests for paired and unpaired data. RESULTS: The percentage of patients with no symptoms or mild symptoms was higher in group A than in group B (differences were highly significant); the mean value of VAS and the overall Lequesne indexes mean score reported in group A was significantly lower than that reported in group B. The same we observed comparing the clinical conditions of group A patients before and after mud-bath therapy. No adverse effects were observed in any of the patients in group A. CONCLUSIONS: The mud-bath therapy at Chianciano Spa significantly improves the clinical conditions of patients with knee osteoarthritis and significantly reduces the frequency and severity of symptoms and the disability they cause.

Gout and related morbid conditions: pharmacological and SPA therapy.

Gouty arthritis is estimated to be the most frequent manifestation of inflammatory arthritis in men aged over 40. Hyperuricemia occurs because of both exogenous and genetic factors, which are particularly influential in some populations such as Taiwan aborigines. Current understanding of the disease etiopathogenesis, its clinical manifestations and the stages of its progression are presented here. The criteria for a correct diagnosis of the disease are also reported, pointing out how to distinguish gout from clinical events of different origin but with a very similar symptomatology. A distinction is made between the agents used to relieve the acute attack (colchicine, nonsteroidal anti-inflammatory drugs, corticosteroids) and those used with the purpose of correcting hyperuricemia and preventing recurrences and complications (allopurinol, uricosurics). Mecha-nisms of action, administration routes, doses, side effects and contraindications of every drug are described. Besides pharmacological therapy, the importance and the efficacy of spa therapy is underlined. Finally, perspectives opened by gene therapy are mentioned.

[The historical-scientific foundations of thalassotherapy: state of the art]. / Le basi storico-scientifiche della talassoterapia: stato dell'arte.

Throughout the ages the interest in the use of sea water in medicine has fluctuated from century to century and from nation to nation. In this paper, the historical development of sea medicine from the ancient Egyptians until the 20th century is given. The medical world has viewed it with different opinions, from very enthusiastic to extremely critical, and from beneficial to harmful. In the last decades, thalassotherapy is receiving renewed attention from many medical specialties and health tourists. The aim of this review is that of offer an update on the real therapeutic possibility of the thalassotherapy. However, the exact therapeutic potential of thalassotherapy still remains largely unknown. Better and more profound scientific evidence for its efficacy is therefore warranted, in particular for its effects on the musculoskeletal system and skin. The main researches belong to the activity of thalassotherapy and the clinic outcomes, namely in osteoarthritis patients, were referred.

[Fine tuning of the many regulations of quality system: the role of the quality in the thermal medicine]. / Messa a punto delle varie normative che regolano il Sistema "Qualità": il ruolo della Qualità nel sistema termale.

In the last decades, quality has imposed itself as a competitive need for firms, and also as a new normative parameter to guarantee the production process and the final product which the costumer buys. In the case of health services, the importance of quality is even greater because of the special value of this service, and the special relationship between the supplier and the costumer/patient. This relationship is often mediated by the State which has to provide the health services and the financial support for them. Thus, also in the case of Thermal Medicine, quality and its certification play a key role for the evaluation of the efficiency of the health service, and tend always more to be part of the health service accreditation process. In this article, we review the development of the idea of quality of service from the ancient Egyptian until the 20th century and we briefly recall the main European and Italian norms. We also examine the norms for the accreditation of the thermal health structures, and we review the main indicators of quality in Thermal Medicine, and the role of scientific research. Finally, we indicate that the cost of the lack of quality can be so prohibitive that the firms which do not follow the new standards, are put out of the market.

[Spa therapy in urolithiasis]. / Cure termali nella calcolosi urinaria.

In the present paper we remind epidemiology, etiopathogenesis and physiopathology of urolythiasis, emphasizing the role of lythogenic and antilythogenic urinary costituents. Mineral waters used in prevention and therapy of urolythiasis are described, namely oligomineral waters and, in uric lythiasis, bicarbonate mineral waters. We stress the activity of oligomineral waters, regarding their very low concentration of solute, presence of oligoelements, and antilythogenic components. At the end, we outline the role of spa therapy in the correction of metabolic disorders, which are etiologic and pathogenetic factors of urolythiasis.
