ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

Nowadays, drug-induced sleep endoscopy (DISE) is performed widely and its validity and reliability has been demonstrated by several studies; in fact, it provides clinical information not available by routine clinical inspection alone. Its safety and utility are promising, but still needs to be improved to reach the level of excellence expected of gold standard tests used in clinical practice. Our study compares the results of clinical and diagnostic evaluation with those of sleep endoscopy, evaluating the correlation between clinical indexes of routine clinical diagnosis and sites of obstruction in terms of number of sites involved, entity of obstruction and pattern of closure. This study consists in a longitudinal prospective evaluation of 138 patients who successfully underwent sleep endoscopy at our institution. Patients were induced to sleep with a low dose of midazolam followed by titration with propofol. Sedation level was monitored using bispectral index monitoring. Our results suggest that the multilevel complete collapse was statistically significantly associated with higher apnoea hypopnea index values. By including partial sites of obstruction greater than 50%, our results also suggest that multilevel collapse remains statistically and significantly associated with higher apnoea hypopnoea index values. Analyzing BMI distribution based on number of sites with complete and partial obstruction there was no significant difference. Finally, analyzing Epworth Sleepiness Score distribution based on number of sites with complete obstruction, there was a statistically significant difference between patients with 3-4 sites of obstruction compared to those with two sites or uni-level obstruction. In conclusion, our data suggest that DISE is safe, easy to perform, valid and reliable, as previously reported. Furthermore, we found a good correlation between DISE findings and clinical characteristics such as AHI and EPS. Consequently, adequate assessment by DISE of all sites of obstruction is very important, not only in patients with low-moderate AHI and EPS, but also in patients with a high AHI or/and high EPS, in particular to plan multilevel surgery that in these latter situations is more demanding since success may be harder to achieve.

ABSTRACT

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.

ABSTRACT

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 (AU)


Este artículo describe los cambios en las funciones digestivas básicas (motilidad, secreción, digestión intraluminal, absorción) que ocurren en el envejecimiento. Los individuos ancianos a menudo presentan una dismotilidad de la musculatura orofaríngea y una alteración de la deglución de los alimentos. Las reducciones en el peristaltismo esofágico y de las presiones del esfínter esofágico inferior (EEI) también son más frecuentes en las personas mayores y pueden causar un reflujo gastroesofágico. La motilidad y el vaciamiento gástricos así como la motilidad intestinal son, por lo general, normales en los individuos ancianos, si bien se han notificado en algunos casos una motilidad y vaciamiento gástricos retardados. La motilidad propulsora del colon también está disminuida y esta alteración se asocia con cambios neurológicos y endocrinos-paracrinos de la pared colónica. En el anciano se describen frecuentemente disminución de las secreciones gástricas (ácido, pepsina) y alteración de la barrera mucosa-bicarbonato, lo cual puede favorecer la úlcera gástrica. A menudo la secreción pancreática exocrina está disminuida, así como el contenido en sales biliares de la bilis. Estos cambios representan mecanismos subyacentes de las disfunciones gastrointestinales sintomáticas del anciano tales como disfagia, enfermedad por reflujo gastroesofágico, dispepsia primaria, síndrome del intestino irritable, estreñimiento primario, maladigestión y disminución de la absorción de nutrientes. También se describe el manejo terapéutico de estos trastornos. Los autores también revisan las enfermedades gastrointestinales que son más frecuentes en el anciano, tales como las gastritis atrófica, la úlcera gástrica, la diverticulosis colónica, los tumores malignos, los cálculos biliares, la hepatitis crónica, la cirrosis hepática, el carcinoma hepatocelular (CHC) y la pancreatitis crónica (AU)

ABSTRACT

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.

ABSTRACT

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).

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

Since 1998, two research groups independently reported the discovery of two novel hypothalamic neuropeptides, called hypocretin-1 and hypocretin-2, respectively many studies have been carried out about their possible functions. One group named these new peptides orexins (A and B) after the Greek word for appetite, since they found that central administration of orexins potently increased food intake in rats. However hypocretins/ orexins are involved in various hypothalamic mechanisms, such as energy homeostasis, neuroendocrine functions, appetite and satiety regulation, vigilance and defence behaviour, sleep and wake regulation. Here is a review of the recent literature, showing some recent discoveries about the link between orexin system, sleep regulation and appetite regulation.

ABSTRACT

The pathophysiology of human narcolepsy is still poorly understood. The hypoactivity of some neurotransmitter systems has been hypothesised on the basis of the canine model. To determine whether narcolepsy is associated with changes in excitability of the cerebral cortex, we assessed the excitability of the motor cortex with transcranial magnetic stimulation (TMS) in 13 patients with narcolepsy and in 12 control subjects. We used several TMS paradigms that can provide information on the excitability of the motor cortex. Resting and active motor thresholds were higher in narcoleptic patients than in controls and intracortical inhibition was more pronounced in narcoleptic patients. No changes in the other evaluated measures were detected. These results are consistent with an impaired balance between excitatory and inhibitory intracortical circuits in narcolepsy that leads to cortical hypoexcitability. We hypothesise that the deficiency of the excitatory hypocretin/orexin-neurotransmitter-system in narcolepsy is reflected in changes of cortical excitability since circuits originating in the lateral hypothalamus and in the basal forebrain project widely to the neocortex, including motor cortex. This abnormal excitability of cortical networks could be the physiological correlate of excessive daytime sleepiness and it could be the substrate for allowing dissociated states of wakefulness and sleep to emerge suddenly while patients are awake, which constitute the symptoms of narcolepsy.

ABSTRACT

AIMS: Erythropoietin (EPO)-deficient anaemia has been described in Type 1 diabetic patients with both severe autonomic neuropathy (AN) and proteinuria. This study was aimed at distinguishing between the effects of AN and nephropathy on haemoglobin and EPO levels in Type 2 diabetic patients at an early stage of diabetic nephropathy. METHODS: In 64 Type 2 diabetic patients (age 52 +/- 10 years, duration 10 +/- 9 years) without overt nephropathy and other causes of anaemia or EPO deficit, we assessed cardiovascular tests of AN, 24-h blood pressure (BP) monitoring, urinary albumin excretion rate (UAE), a full blood count, and serum EPO. RESULTS: Although the Type 2 diabetic patients with AN did not show differences in haemoglobin and EPO when compared with patients without AN, the presence of haemoglobin < 13 g/dl was associated with the presence of AN (chi(2)= 3.9, P < 0.05) and of postural hypotension (chi(2)= 7.8, P < 0.05). In a multiple regression analysis including as independent variables gender, body mass index, duration of diabetes, smoking, creatinine, 24-h UAE, 24-h diastolic BP, ferritin, erythrocyte sedimentation rate, and autonomic score, we found that the only variables independently related to haematocrit were autonomic score, ferritin and erythrocyte sedimentation rate. Finally, the physiological inverse relationship between EPO and haemoglobin present in a control group of 42 non-diabetic non-anaemic subjects was completely lost in Type 2 diabetic patients. The slopes of the regression lines between EPO and haemoglobin of the control subjects and the Type 2 diabetic patients were significantly different (t = 14.4, P < 0.0001). CONCLUSIONS: This study documents an early abnormality of EPO regulation in Type 2 diabetes before clinical nephropathy and points to a contributory role of AN in EPO dysregulation.

ABSTRACT

Attempts to analyse the sleep structure of patients with eating disorders have so far led to conflicting results. Polygraphic findings suggest that patients with bulimia nervosa are not easily distinguishable from age-matched controls, whereas anorexic patients show some abnormalities in sleep efficiency and sleep architecture. Nevertheless, both bulimic and anorexic patients complain of poor quality sleep. The aim of this study was to evaluate the microstructure of sleep in anorexia and bulimia by analysing arousal (following the rules of the American Sleep Disorders Association) and the cyclic alternating pattern (CAP). The results confirmed the presence of sleep disturbances in eating disordered patients: an increase in arousal length and the CAP rate. They also seem to confirm the findings of previous studies suggesting that altered sleep in eating disordered patients may be related to their body mass index (BMI) and psychopathological status.

ABSTRACT

Geriatric patients often complain about sleep disorders, but many of the typical sleep disturbances in the elderly are thought to be normal consequences of old age and go underdiagnosed and undertreated. Sleep disorders are estimated to affect nearly 50% of older persons. Most frequently the elderly suffer from Sleep Disordered Breathing (SDB), Periodic Limb Movements in Sleep (PLMS), Restless Legs Syndrome (RLS), morning headaches, circadian rhythm disorders, excessive daytime sleepiness, Obstructive Sleep Apnea Syndrome (OSAS), and insomnia. This review describes all these common sleep problems in the older population and their possible treatment.
