Strategies for Disease Prevention and Health Promotion in Urban Areas: The Erice 50 Charter.

The Erice 50 Charter titled "Strategies for Diseases Prevention and Health Promotion in Urban Areas" was unanimously approved at the conclusion of the 50th Residential Course "Urban Health. Instruments for promoting health and for assessing hygienic and sanitary conditions in urban areas", held from 29th March to 2nd April 2017 in Erice, at the "Ettore Majorana" Foundation and Centre for Scientific Culture and promoted by the International School of Epidemiology and Preventive Medicine "G. D'Alessandro" and the Study Group "Building Hygiene" of the Italian Society of Hygiene, Preventive Medicine and Public Health (SItI). At the conclusion of the intense learning experience during the Course, with more than 20 lectures, workshops and long-lasting discussions between Professors and Students, the participants identified the major points connecting urban features and Public Health, claiming the pivotal role of urban planning strategies for the management of Diseases Prevention and Health Promotion activities. The Erice 50 Charter is configured as a Decalogue for Healthy Cities and as a Think Tank for designing effective strategic actions and best practices to develop urban regeneration interventions and improve the urban quality of contemporary cities. The Decalogue is structured into the following key strategic objectives: 1. Promoting urban planning interventions that address citizens towards healthy behaviours; 2. Improving living conditions in the urban context; 3. Building an accessible and inclusive city, with a special focus on the frail population; 4. Encouraging the foundation of resilient urban areas; 5. Supporting the development of new economies and employment through urban renewal interventions; 6. Tackling social inequalities; 7. Improving stakeholders' awareness of the factors affecting Public Health in the cities; 8. Ensuring a participated urban governance; 9. Introducing qualitative and quantitative performance tools, capable of measuring the city's attitude to promote healthy lifestyles and to monitor the population's health status; 10. Encouraging sharing of knowledge and accessibility to informations. Finally, all the participants underlined that a multidisciplinary team, composed of Physicians specialized in Hygiene, Preventive Medicine, Public Health and Technicians as Architects, Urban planners and Engineers, is needed to deepen the research topic of Urban Health.

Persistent orthostatic headache without intracranial hypotension: which treatment?

Orthostatic headache can be the leading symptom of intracranial hypotension, however, not all orthostatic headaches are due to cerebrospinal fluid leaks and these forms can be a clinical problem, especially for treatment. Aim of this study was to review patients with persistent orthostatic headache in whom a detailed head and spinal MRI follow-up did not reveal any sign of intracranial hypotension and to evaluate which treatment can be considered the first choice. Patients admitted to our headache center for evaluation of persistent orthostatic headache and followed after first admission with clinical and neuroradiological controls were systematically reviewed. 11 patients (7 M, 4 F) followed in a period lasted from 10 months up to 2 years were studied. Six patients (54, 5 %) reported a MRI performed previously elsewhere with a suspect diagnosis of intracranial hypotension which was not confirmed at MRI at our hospital such as during the radiological follow-up. Three patients (27.2 %) had developed orthostatic headache short after a neck or head trauma with no evidence of neuroradiological pathological signs and two patients (18 %) had a previous history of psychiatric disorder. We administrated antidepressants in five patients, atypical neuroleptic in three patients, association of antidepressant and antipsychotic in one patient and muscle relaxants in two cases. All patients showed a certain improvement of headache in the weeks after introduction of the pharmacological treatment; six (54, 5 %) had pain relief during the follow-up and five (45, 5 %) were pain free at the last clinical control. We found out that patients with the best outcome were the ones treated with antidepressants. Persistent orthostatic headache without any neuroradiological sign of intracranial hypotension is a challenging problem for clinicians. Although the International Classification of Headache Disorders (ICHD-3 beta version) criteria suggests the possibility of epidural blood patch in orthostatic headache without causes, we believe that a pharmacological treatment tailored on each patient should be always considered and antidepressants can be the first choice.

Difficulties in work activities and the pervasive effect over disability in patients with episodic and chronic migraine.

Migraine is associated with reduced productivity in work-related activities. The degree to which problems with work are, in turn, associated to the level of migraine-related disability as well as to headache frequency has been poorly explored. The aim of the study was to assess if migraine patients with different degrees of work difficulties showed a different level of migraine-related disability. A consecutive sample of patients with episodic migraine (EM) or with chronic migraine (CM) with medication overuse (MO) attending the Headache Centre of the Neurological Institute C. Besta of Milan was studied. All patients completed the MIDAS and the WHODAS 2.0 questionnaires. The total scores of both questionnaires, frequency of headaches, average pain intensity, and the scores of each subscale of the WHODAS 2.0 were calculated separately for EM and CM patients. The score of WHODAS 2.0 "Work difficulties" subscale was used to divide the studied patients into two groups, i.e. those above and those below the median "Work difficulties" subscale score. Independent sample t test was used to compare these two groups as far as all the other studied variables. A total of 296 patients (102 with EM and 194 with CM-MO) were enrolled. Patients with higher work difficulties score also displayed higher scores in the other WHODAS 2.0 subscales; for those with CM-MO, the differences were significant. The results of this study indicate that having more and more severe workplace problems is associated to a higher disability level in migraineurs. Further studies are needed to better understand workplace disability in different migraine forms, particularly in a qualitative way.

Prevalence and profile of obsessive-compulsive trait in patients with chronic migraine and medication overuse.

Patients with chronic migraine (CM) and medication overuse headache (MOH) have high frequency of psychiatric comorbidity or psychopathological traits, the presence of which can influence the clinical course. The presence of subclinical obsessive compulsive disorder (OCD) is underestimated in migraine patients. The aim of this study was to estimate the prevalence and profile of obsessive-compulsive (OBS) trait in a sample of CM patients with MOH using the OBS questionnaire of Spectrum Collaborative Project. According to the new international classification of headache disorders (ICHD-III beta) criteria, 106 patients (15 M, 91 F, mean age 47.3 years) were selected in a consecutive clinical series. Our results showed that 36 % of patients with CM and MOH were positive at OBS-questionnaire. As far as the profile of OBS trait, we performed an evaluation of prevalence of items separating the first part of the questionnaire (childhood/adolescence and doubts in lifetime) from the other five domains: 21 % of the patients showed prevalence of items in childhood/adolescence domain; 79 % in doubts in lifetime domain; as for other five domains, 10.5 % of patients had prevalence of pathological answers among hypercontrol, 5.2 % in spending time, 23.7 % in perfectionism, 29 % in repetition and automation, and 31.5 % in specific themes (obsessive thoughts). The presence of subclinical OCD in migraine patients, and the link between progression to CM, particularly through MO, and OBS trait is still not well defined. The use of specific tools to assess this possible comorbidity should be encouraged in clinical and research settings.

Oxidative and proteolytic profiles of the right and left heart in a model of cancer-induced cardiac cachexia.

Cardiac cachexia is a syndrome that has received increased attention in recent years. Although an association between proteolysis and cardiac cachexia has been proposed, the direct influence of oxidative stress on the process has not been demonstrated. In the present study, the right (RH) and left (LH) hearts (atrium and ventricle of each side of the heart) were collected from rats at the 5th and 10th days after phosphate buffer (control) orWalker-256 solid tumour implantation. Immediately after sacrifice, cachexia was determined in tumour-bearing animals by the formula: [(inicial body weight-final body weight+tumour weight+weight gain of control group)/(initial body weight+body mass gain of control group)]×100%; RH and LH were stored until use. Oxidative stress and proteolysis were determined in each collected sample. In addition, heart samples were collected from a separate set of animals to determine the thickness of the left and right ventricles. Cachexia values increased over time after tumour implantation from 6.85% at the 5th day to 17.76% at the 10th day. There was no significant difference in LH wet weight and ventricle thickness compared with the control, where as RH wet weight (0.109±0.09g at the 5th day and 0.093±0.09g at the 10th day) and thickness (420±16µm at the 5th day and 279±08µm at the 10th day) were significantly decreased at both time points when compared with control values (0.153±0.06g and 607±21µm, respectively). tert-Butyl-stimulated chemiluminescence analysis revealed a significant increase in the LH and decrease in the RH oxidative stress profiles. Carbonylated proteins increased in the LH (140%, p<0.05) and RH (100%, p<0.05) at the 5th day, and significantly decreased in both sides on the 10th day compared to controls. Chemotrypsin-like, caspase-like, and calpain-like activities were evaluated by chemiluminescence, and only calpain-like activity was found to increase at the 5th day in the RH. In the LH, all proteolytic activities systems were decreased when compared with controls. Together, these results demonstrate that oxidative stress appears to play a different role in mass modulation on the LH and RH. The proteolytic systems evaluated herein also appear to have different effects on the responses developed during cardiac cachexia in the two sides of the heart.

Occipital neurostimulation in primary headaches: update.

A subset of headache patients are chronic and results refractory to standard medical treatments, they are unsatisfied or unable to tolerate the side effects of medications. In the lack of more effective prophylactic treatment, there is need of alternative approach. Migraine is conceptualized as a chronic and potentially progressive disorder. It is conceivable that more aggressive therapeutic efforts could be warranted in drug-refractory chronic migraine. In this prospective, the new, device-based therapies that allow to affect brain function in less invasive ways may represent a therapeutic opportunity. Peripheral occipital neurostimulation resulted in several trials and case reports to be beneficial in a large variety of headache and craniofacial pain disorders, with chronic primary headache the most studied. We comment on our experience in the application of ONS in drug-refractory chronic cluster headache and chronic migraine patients.

Positive outcome of occlusal freeway space reestablishment in patients with medication overuse due to chronic migraine.

Considering the great chapter of migraines, it is important to note the signs and symptoms caused by an alteration of the relationship of the facial musculature and the occlusal freeway space (FWS) that is the distance from maximal intercuspation to the habitual rest position (measurable in 1.4-2.5 mm). To any mandible position changing (detected by periodontal, muscle and joint proprioceptors), there is an influence on the neuromuscular system and then an alteration of the FWS. A group of 60 patients with chronic migraine (CM) underwent a withdrawal of overused medication and were subjected to electromyographic and kinesiographic evaluation. All those who presented an alteration of the FWS at rest position have been subjected to treatment with orthosis device for about 12 months. The aim of our work is to obtain and define a correct mandibular position, physiological, in agreement with the neuromuscular structures of the patient. Clinical results obtained on this pool of patients, in terms of reduction of the VAS, let us understand the importance of the inviolability of the FWS and to eliminate any type of mandibular deviation with respect to the closure trajectory induced by TENS in patients suffering from CM.

Outcome of patients with chronic migraine with medication overuse and depression after duloxetine: influence of coexisting obsessive compulsive disorder.

Patients with chronic migraine (CM) and medication overuse (MO) have high frequency of psychiatric comorbidity. Aims of this open label, prospective, independent study were: to evaluate the efficacy of duloxetine in a sample of patients with MO due to CM and with concomitant depression; to investigate, if the presence of OCD influences the outcome in this subgroup of patients. A total of 50 consecutive patients (40 F,10 M, aged 20-65 years, mean 39.4 years) from those attending our Headache Center to undergo an inpatient withdrawal programme followed by anti-migraine prophylaxis was enrolled. After a 1-month baseline period, all patients were prescribed duloxetine 30 mg in the morning for the first week, and 60 mg for the following 12 weeks. They filled a daily headache diary during the whole study period. They also completed Hamilton depression rating scale (HDRS) and migraine disability assessment scale (MIDAS) at baseline and at the 12-week follow-up. The primary outcome measure was the percentage of responders, i.e. of patients with a reduction ≥50 % in headache frequency as well as in symptomatic drug consumption. Comparison between patients with and without OCD was performed. Our results showed a rather high responder rate in the total sample (64 %), while none of the patients with OCD fell among responders. MIDAS and HDRS scores had a more evident decrease in patients without OSD. These findings suggest that duloxetine may be effective in patients with MO due to CM and with comorbid depression. They also confirm the importance of a systematic assessment of the psychopathological profile in these patients, and indicate that clinicians should be aware of the relevant prognostic role of OCD in favoring a poor outcome and persistent disability in headache patients with MO.

Identification of early predictors of clinical outcomes of COVID-19 outbreak in an Italian single center using a machine-learning approach.

OBJECTIVE: SARS-CoV-2 disease (COVID-19) has become a pandemic disease, determining a public health emergency. The use of artificial intelligence in identifying easily available biomarkers capable of predicting the risk for severe disease may be helpful in guiding clinical decisions. The aim of the study was to investigate the ability of interleukin (IL)-6, troponin I, and D-dimer to identify patients with COVID-19 at risk for intensive care unit (ICU)-admission and death by using a machine-learning predictive model. PATIENTS AND METHODS: Data on demographic characteristics, underlying comorbidities, symptoms, physical and radiological findings, and laboratory tests have been retrospectively collected from electronic medical records of patients admitted to Policlinico A. Gemelli Foundation from March 1, 2020, to September 15, 2020, by using artificial intelligence techniques. RESULTS: From an initial cohort of 425 patients, 146 met the inclusion criteria and were enrolled in the study. The in-hospital mortality rate was 15%, and the ICU admission rate was 41%. Patients who died had higher troponin I (p-value<0.01) and IL-6 values (p-value=0.04), compared to those who survived. Patients admitted to ICU had higher levels of troponin I (p-value<0.01) and IL-6 (p-value<0.01), compared to those not admitted to ICU. Threshold values to predict in-hospital mortality and ICU admission have been identified. IL-6 levels higher than 15.133 ng/L have been associated with a 22.91% risk of in-hospital mortality, and IL-6 levels higher than 25.65 ng/L have been associated with a 56.16% risk of ICU admission. Troponin I levels higher than 12 ng/L have been associated with a 26.76% risk of in-hospital mortality and troponin I levels higher than 12 ng/L have been associated with a 52.11% risk of ICU admission. CONCLUSIONS: Levels of IL-6 and troponin I are associated with poor COVID-19 outcomes. Cut-off values capable of predicting in-hospital mortality and ICU admission have been identified. Building a predictive model using a machine-learning approach may be helpful in supporting clinical decisions in a more precise and personalized way.

Impact of COVID-19 pandemic on patients affected by peripheral arterial disease: an Italian single-center study.

OBJECTIVE: Coronavirus disease 2019 (COVID-19) has evolved into a global pandemic, affecting a wide range of medical and surgical specialties. During COVID-19, we assisted in the reallocation of medical resources and services, as well as social distancing measures, and many patients with chronic diseases and comorbidities may have experienced difficulties in obtaining the correct medical care. The aim of the study was to investigate the impact of the COVID-19 pandemic on major adverse cardiovascular events (MACE) and major adverse limb events (MALE) in patients with peripheral arterial disease (PAD) and chronic limb-threatening ischemia (CLTI), compared to previous years. PATIENTS AND METHODS: We evaluated 1,335 hospital admissions of 877 patients with PAD admitted to Policlinico A. Gemelli Hospital between January 2017 and February 2020 and 368 hospital admissions of 272 patients with PAD admitted to the Policlinico A. Gemelli Hospital between March 2020 and March 2021. Data on demographic characteristics, comorbidities, symptoms, physical and radiological findings, laboratory tests, and routine visits before or after discharge were collected from electronic medical records. RESULTS: Emergency room (ER) admissions among PAD patients during COVID-19 were higher than before the pandemic [190 (51.63%) vs. 579 (43.37%), p = 0.01]. A MACE was found in 78 (5.84%) pre-pandemic hospitalizations and 126 (34.24%) pandemic hospitalizations (p < 0.01). A MALE was identified in 942 (70.56%) pre-pandemic hospitalizations and 331 (89.95%) pandemic hospitalizations (p < 0.01). Amputation rates during the pandemic were higher than before the pandemic [80 (21.74%) vs. 191 (14.31%), p < 0.01]. The number of in-hospital deaths did not differ between the pandemic and pre-pandemic periods [11 (2.99%) vs. 51 (3.82%), p = 0.55]. CONCLUSIONS: In patients with PAD and CLTI, the number of MACE, MALE, and amputations was higher during the COVID-19 period compared to the three years before the pandemic.

Molecular subtype is determinant on inflammatory status and immunological profile from invasive breast cancer patients.

Breast cancer consists in a chronic inflammatory disease with multiple biological and clinical behaviors. Based on high throughput technologies data, this disease is currently classified according to the molecular expression of estrogen (ER), progesterone (PR) and human epidermal growth factor (HER-2) receptors. In this study, we defined the inflammatory profile of the main molecular subtypes of breast cancer patients: luminal (ER and PR positive, HER-2 negative), HER-2 enriched (HER-2 positive) and triple negative (ER, PR and HER-2 negative). Cytokines panel was assessed by measurement of TNF-α, TGF-ß, IL-1, IL-10 and IL-12 plasmatic levels. Oxidative profile was assessed by determination of lipid peroxidation, total antioxidant capacity of plasma, malondialdehyde levels, carbonyl content and nitric oxide (NO). Clinical data were correlated with inflammatory findings. Our findings demonstrated that patients bearing the luminal subtype displayed high TNF-α, TGF-ß and enhanced oxidative stress levels associated with reduced IL-12. HER-2-enriched group exhibited higher levels of TNF-α, IL-12 and TGF-ß associated with enhanced oxidative stress. Triple-negative subtype exhibited the most aggressive profile of disease behavior, with reduction in both TNF-α and TGF-ß, with high levels of lipid peroxidation and NO. The clinical importance of our findings lies in the fact that the inflammatory status varies in distinct ways due to molecular subtype of breast cancer, opening potential therapeutic targets to future therapies.

Immunological effects of taxol and adryamicin in breast cancer patients.

Antineoplastic chemotherapy still consists in the major first-line therapeutics against cancer. Several reports have described the immunomodulatory effects of these drugs based on in vitro treatment, but no previous data are known about these effects in patients and its association with immunological-mediated toxicity. In this study, we first characterize the immunological profile of advanced breast cancer patients treated with doxorubicin and paclitaxel protocols, immediately after chemotherapy infusion. Our findings included an immediate plasmatic reduction in IL-1, IL-10, and TNF-α levels in doxorubicin-treated patients, as well as high levels of IL-10 in paclitaxel patients. Further, it was demonstrated that both drugs led to leukocytes oxidative burst impairment. In vitro analysis was performed exposing healthy blood to both chemotherapics in the same concentration and time of exposition of patients, resulting in low IL-10 and high IL-1ß in doxorubicin exposition, as low TNF-α and high IL-1 in paclitaxel treatment. Nitric oxide levels were not altered in both in vivo and in vitro treatments. In conclusion, our data revealed for the first time that the immediate effects of chemotherapy could be mediated by cytokines signaling in patients and that the results observed in patients could be a resultant of host immune cells activation.

Oxidative stress and hematological profiles of advanced breast cancer patients subjected to paclitaxel or doxorubicin chemotherapy.

Several adverse effects of chemotherapy treatments have been described, and most of these effects are associated with direct interactions between blood cells and indirect effects generated during the oxidative metabolism of antineoplastic drugs. In this study we evaluated the oxidative systemic status and hematological profiles of breast cancer patients with advanced ductal infiltrative carcinoma treated with doxorubicin (DOX) or paclitaxel (PTX) within 1 h after chemotherapy. Blood analyses included evaluation of hemogram, pro-oxidative markers, and antioxidant status. The results showed that advanced breast cancer diseased (AD) patients without previous chemotherapy presented anemia and high oxidative stress status characterized by elevated levels of lipid peroxidation and nitric oxide, and reduced catalase activity when compared with controls. DOX-treated patients exhibited increased anemia and reduced antioxidant status, which was revealed by decreases in reduced glutathione levels and the total antioxidant capacity of plasma; however, these changes did not lead to further increases in lipid peroxidation or carbonyl proteins when compared with the AD group. PTX-treated patients also showed increased anemia, lactate dehydrogenase leakage, and enhanced lipid peroxidation. These data reveal for the first time that patients subjected to chemotherapy with DOX or PTX present immediate systemic oxidative stress and red blood cell oxidative injury with anemia development. These findings provide a new perspective on the systemic redox state of AD and patients subjected to chemotherapy regarding oxidative stress enhancement and its possible involvement in the aggravation of chronic anemia.

Differential oxidative status and immune characterization of the early and advanced stages of human breast cancer.

Breast cancer is the malignant neoplasia with the highest incidence in women worldwide. Chronic oxidative stress and inflammation have been indicated as major mediators during carcinogenesis and cancer progression. Human studies have not considered the complexity of tumor biology during the stages of cancer advance, limiting their clinical application. The purpose of this study was to characterize systemic oxidative stress and immune response parameters in early (ED; TNM I and II) and advanced disease (AD; TNM III and IV) of patients diagnosed with infiltrative ductal carcinoma breast cancer. Oxidative stress parameters were evaluated by plasmatic lipoperoxidation, carbonyl content, thiobarbituric reactive substances (TBARS), nitric oxide levels (NO), total radical antioxidant parameter (TRAP), superoxide dismutase, and catalase activities and GSH levels. Immune evaluation was determined by TNF-α, IL-1ß, IL-12, and IL-10 levels and leukocytes oxidative burst evaluation by chemiluminescence. Tissue damage analysis included heart (total CK and CKMB), liver (AST, ALT, GGT), and renal (creatinine, urea, and uric acid) plasmatic markers. C-reactive protein (CRP) and iron metabolism were also evaluated. Analysis of the results verified different oxidative stress statuses occur at distinct cancer stages. ED was characterized by reduction in catalase, 8-isoprostanes, and GSH levels, with enhanced lipid peroxidation and TBARS levels. AD exhibited more pronounced oxidative status, with reduction in catalase activity and TRAP, intense lipid peroxidation and high levels of NO, TBARs, and carbonyl content. ED patients presented a Th2 immune pattern, while AD exhibited Th1 status. CRP levels and ferritin were increased in both stages of disease. Leukocytes burst impairment was observed in both the groups. Plasma iron levels were significantly elevated in AD. The data obtained indicated that oxidative stress enhancement and immune response impairment may be necessary to ensure cancer progression to advanced stages and may result from both host and tumor inflammatory mediators.

Drug-resistant chronic migraine: the Italian GON project.

Chronic daily headache is a major problem due to severe disability and high socio-economic costs. In the last years, some trials have shown potential benefit from new therapeutic approach by occipital neurostimulation techniques, already applied with some success for the treatment of chronic cluster headache. Due to the extremely heterogeneous population suffering from refractory chronic daily headaches, we propose a national multicenter experimental study involving Italian ANIRCEF Headache Centres with the aim to evaluate the efficacy of occipital neurostimulation in a selected group representative for the drug-resistant chronic migraine. Patients with chronic migraine according to Manzoni's modified IHS criteria-2011, with or without medication overuse headache, will be selected. Duration of illness should be at least 2 years and pharmacological refractoriness defined strictly for experimental-surgical purposes as those patients who have properly tried without success almost all available classes of prophylactic medications. Those presenting with medication overuse should have tried at least two previous detoxification treatments. A full psychopathological assessment will be performed by a psychiatrist, to exclude mainly psychotic disorder, ongoing severe status of an affective disorder, severe post traumatic stress disorder. Headache characteristics and abortive treatments used will be reported daily on a predisposed diary during 3-month baseline and continuously through the post implant follow up, while disability and QoL scale (MIDAS, SF-12) will be completed baseline, 6 and 12 months after implant.

Could thymoglobulin increase hemorrhagic risk in the perioperative transplantation period of sensitized kidney recipients?

OBJECTIVE: It has been described that thymoglobulin could increase the risk of infections and malignancies, in comparison to basiliximab. Leukopenia and thrombocytopenia are also more common within the first days after transplantation among thymoglobulin patients. Our objective was to analyze bleeding complications in this subset of patients. MATERIAL AND METHODS: Bleeding complications were evaluated among 515 renal transplants carried out at our institution between 2012 and 2018. We compared patients treated with thymoglobulin (Group 1, N=91) with those treated with basiliximab (Group 2, N=424). RESULTS: We found differences in platelet decrease: 95,142.2 (55,339.6) in Group 1 and 52,364.3 (69,116.6) in Group 2 (P=0.001), number of patients with severe thrombocytopenia (<75,000/mm3) (20.8% vs. 3.7%, P=0.001), number of blood units transfused (3.25 (0.572) vs. 2.2 (0.191, P=0.028) and percentage of patients that required surgery due to bleeding (18.2% vs. 7.7%, P=0.046). In a multiple lineal regression multivariable analysis (dependent variable was number of blood units transfused), only age [OR 0.037, 95% CI (0.003-0.070)] and type of immunosuppression [OR 1.592, 95% CI (1.38-2.84)] showed statistical significance. CONCLUSIONS: The use of thymoglobulin in the perioperative transplantation period could increase bleeding complications. In our series, in the group of patients with thymoglobulin, severe thrombocytopenia was 6 times more frequent, and active bleeding that required surgery was also 2.5 times more frequent. One way to continue with the use of this immunosuppression agent, might be to adjust the dose instead of discontinuing it. The use of thymoglobulin should be a factor to consider in the postoperative period of these patients.

Polytherapy for the prophylaxis of chronic migraine: an Italian survey.

Chronic migraine (CM) represents an important medical issue, due to morbidity, high disability, presence of comorbidities, and medication overuse (MO). The prophylaxis of CM has not been extensively explored so far. Patients with CM are often treated with two or more compounds, although there is no clear evidence that polytherapy may be superior to monotherapy. We evaluated the percentage of prescription of polytherapy for the prophylaxis of CM in a clinical sample. We examined the charts of 98 CM patients admitted to our Headache Center for inpatient withdrawal program to stop MO. Results showed that only one drug for prophylaxis was prescribed in 20.4% cases, two or more drugs in 79.6%, with 63.3% of the total sample falling in the group "true polytherapy", i.e. all the drugs prescribed on daily basis were given to treat CM, and not only to treat concomitant conditions. In more than 60% cases a combination of drugs indicated for migraine prophylaxis and drugs only indicated for other conditions (mainly for psychiatric disorders) was prescribed. Our survey indicates that polytherapy may be rather common in CM, and suggests that comorbidities may strongly influence treatment choices.

Treatment of alterations in CSF dynamics.

Alterations of the intracranial pressure (ICP) may be present in several conditions. The aim of this brief review is to focus on two relatively rare conditions characterized by alterations in cerebro-spinal fluid dynamics--Spontaneous Intracranial hypotension (SIH) and Idiopathic Intracranial hypertension (IIH)--in which headache is one of the key symptoms. The most relevant clinical features, the expected MRI findings, and the therapeutic options regarding both conditions are discussed.

Psychopathological profile of patients with chronic migraine and medication overuse: study and findings in 50 cases.

Patients with chronic migraine (CM) have high frequence of psychiatric comorbidity or psychological distress. The presence of depression, anxiety, panic or obsessive disorders in these patients contributes to poor quality of life and can influence prognosis and treatment. A systematic investigation of psychiatric comorbidity is needed in patients with CM especially in those with medication overuse (MO), in order to reach a more comprehensive clinical management. We assessed the psychological profile of 50 patients, 40 women and 10 men suffering from CM with MO. The Spectrum Project, a complementary way of describing and assessing psychopathology with structured clinical interviews, was used for the psychological evaluation of the patients to explore personality traits. Spectrum instruments mood disorders (MOODS), panic agoraphobic disorders (PAS) and obsessive-compulsive disorder (OBS) were applied to study patients. OBS-questionnaire was positive in 28% of the patients, MOODS-questionnaire in 44%, PAS-questionnaire in 46%. 19 on 50 patients (38%) presented positivity to 2 or to all questionnaires in variable associations. None of the patients of the studied group had complete normal findings in the questionnaires. Clinical records of patients with OBS-questionnaire positivity showed a worse clinical course and tendency to relapse. These results suggest that psychological assessment is an essential step in the evaluation and treatment of patients with CM and MO. The remarkable percentage of OBS-questionnaire positivity in this group indicates that obsessive-compulsive trait represents besides depression and anxiety, a major risk of chronification and overusing.

Costs of hypothalamic stimulation in chronic drug-resistant cluster headache: preliminary data.

In about 20% of chronic cluster headache (CH) cases, drugs may become ineffective. Under these circumstances, steroids and triptans are frequently employed leading to fearful side effects in one and high costs in the other. The direct costs of drug-resistant chronic CH are mainly due to frequent medical consultations and frequent use of expensive drugs. In recent years, hypothalamic stimulation has been employed to treat drug-resistant chronic CH patients suffering multiple daily attacks and long-term results from different centres show a 60% overall benefit. Nine years since the introduction of this technique, we attempt a preliminary analysis of the direct costs of hypothalamic stimulation based on patients treated at our centre. We estimated the following direct costs as follows: cost of neurosurgery plus cost of equipment (electrode, connection and impulse generator = 25,000 euro), cost of hospital admissions in long-term follow-up (2,000 euro per admission), cost of single sumatriptan injection (25 euro). Number of daily sumatriptan injections in the year before and for each year after hypothalamic implantation was obtained from headache diaries. To estimate the saving due to the reduction in sumatriptan consumption following hypothalamic stimulation, we calculated the following for each year of follow-up after surgery: number of sumatriptan injections in the year before surgery minus number of sumatriptan injections in each year, updated to December 2008. In our 19 implanted patients, the costs of neurosurgery plus cost of equipment were 475,000 euro; the costs of hospital admissions during follow up were 250,000 euro. Reduction in sumatriptan consumption resulted in a total saving of 3,573,125 euro. Hence, in our 19 patients, the sumatriptan saving (3,573,125 euro) minus the direct costs due to operation and follow up hospitalisations (475,000 + 250,000) euro is equal to 2,848,125 euro. These preliminary results indicate that hypothalamic stimulation is associated with marked reduction of direct costs in the management of complete drug-resistant chronic CH.
