RESUMEN
OBJECTIVE: The aim of this study is to assess whether the touch of osteopathic manipulative treatment (OMT) can affect the endogenous production of oxytocin in full-term pregnant women and the assessment of well-being following the treatment. PATIENTS AND METHODS: In this study have been enrolled 57 pregnant women at full-term pregnancy (37th-41st week) for evaluation of the concentration of salivary oxytocin 2 minutes before and 2 minutes after a single session of OMT by an osteopath lasting for 30 minutes. Pre-OMT and post-OMT saliva samples were collected with the use of Salivette® salivary swabs. 7 salivary swabs were excluded from the analysis. 50 samples were analyzed with an appropriate ELISA kit. RESULTS: The mean OT salivary concentration pre-OMT was 89.98±16.39, and post-OMT was 100.60±19.13 tends to increase with p=0.0000051. In multivariate analysis, two subgroups show interesting data in the mean difference in OT salivary concentration post-OMT: women with painful contractions (p=0.06) and women under 35 years (p=0.09). CONCLUSIONS: The results of this study demonstrate that the effectiveness of OMT-increasing endogenous oxytocin is statistically significant in full-term pregnant women. The sensation of well-being found in most women indicates that there has been a predominantly central rather than peripheral oxytocin release after OMT.

BACKGROUND: Peripheral nerve field stimulation (PNFS) is a novel neurosurgical procedure consisting of implantation of subcutaneous leads in specific painful areas in different types of painful, drug-resistant syndromes. The objective of this study was to evaluate the efficacy of PNFS in several patients affected by different chronic neuropathic pain syndromes, along with its risks, limits and possible correlation between the results achieved and the patients' main symptoms. METHODS: Twenty-two patients affected by different types of chronic neuropathic pain were submitted to PNFS at the Department of Neurosurgery of the Istituto Neurologico "C. Besta" in Milan between July 2009 and July 2013. The visual analog scale (VAS) and variations in the use of analgesic drugs, along with complications, were considered to assess results. RESULTS: In 59 % of our patients, an average pain reduction of 5.50 points on the visual analog scale was observed (average pre-implant score 8.86 and average post-implant score 3.36). These patients reduced their analgesic drug use after PNFS. We observed no early or long-term complications after our last follow-up evaluation. CONCLUSIONS: PNFS can be considered an effective and safe option to treat carefully selected, drug-resistant and chronic neuropathic pain patients; the reversibility of the procedure and its lack, at least in our hands, of long-term complications may contribute to wider use of this procedure.

Two patients with uncontrollable aggressive behaviour underwent the placement of stimulating leads in the posterior hypothalamus (pHyp). One patient had also multifocal refractory epilepsy. Microrecordings were obtained in both patients during surgery under general anaesthesia. Firing rate, interspike intervals and oscillatory discharge patterns were analysed in 14 neurons. A mean discharge rate of 19 Hz, and oscillatory activity at 7-8 Hz were recorded in the first patient with aggressiveness and epilepsy. In the second patient the mean firing rate was 10 Hz, with evidence of both tonic and random firing patterns. Previous studies in patients with cluster headache showed that a discharge rate around 20 Hz and lack of a specific rhythmic pattern were the most consistent characteristics of neuronal discharge in this area. Our present findings therefore would suggest that the pattern of discharge of neurons in the pHyp should be evaluated with reference to the presence of concurrent pathology.

Cluster headache, the most severe of primary headache conditions for functional and social impairment it provokes, has been recently the object of a great amount of clinical, physiopathological, surgical and functional neuroradiological studies aimed to uncover the real mechanisms which underlie its disabling manifestations. Refinement of methodological and systematic features of multidisciplinary researches in this field has been allowing for more and more precise delineations of the role of both peripheral and central nervous system's contribution in pathophysiology of the disease. Aim of this manuscript is the report of the present knowledge in the role of the different surgical options in the treatment of drug-resistant cluster headache and Short-lasting Unilateral neuralgiform headache attacks with Conjunctival injection and Tearing (SUNCT), which take into account their different hypothesized pathological mechanisms and which comprise central nervous system's approach (Deep Brain Stimulation [DBS] and peripheral approach, namely Occipital Nerve Stimulation (ONS) and Vagal Nerve Stimulation (VNS).

AIM: The induction of sleep would depend on interaction between gabaergic system and the pineal gland through its main hormone melatonin. Until few years ago benzodiazepines were the only drugs effective in the treatment of insomnia. Recently, however, both melatonin and acupressure have appear to be active in sleep disorders. The aim of study was to evaluate the efficacy of HT 7 point acupressure in insomnia. METHODS: The study enrolled 25 patients affected by sleep disorders, 14 of whom had a neoplastic disease. They were treated by HT 7 stimulation for al least two consecutive weeks using a medical device named H7 Insomnia Control. RESULTS: An improvement in the quality of sleep was achieved in 15/25 (60%) patients, with a more evident efficacy in cancer patients (11/14 [79%]). CONCLUSION: This study confirms previous clinical data showing the efficacy of acupressure in the treatment of sleep disorders, particularly in cancer-related insomnia.

BACKGROUND: The recent advances in the psychooncological and psychoneuroimmunological investigations of cancer patients has allowed the rediscovery of the importance of spiritual faith in influencing the clinical course of neoplastic disease, not only in terms of supportive care but also as a potential prognostic variable. MATERIALS AND METHODS: Clinical criteria were worked out to explore the existence of a real status of faith, in an attempt to correlate the degree of faith with the clinical response to chemotherapy, consisting of cisplatin plus gemcitabine, and the overall survival time in a group of 50 metastatic nonsmall cell lung cancer patients. RESULTS: The tumor response rate achieved in patients with a high degree of faith was significantly higher than in the other group of patients. Moreover, the mean postchemotherapeutic lymphocyte number was significantly higher in the patients with evident spiritual faith than in the other patients. Finally, the percent age of 3-year survival observed in the patients with a high degree of faith was significantly higher than that in the patients with a low faith score. CONCLUSION: This preliminary study suggests that spiritual faith may positively influence the efficacy of chemotherapy and the clinical course of neoplastic disease, at least in lung cancer, by improving the lymphocyte-mediated anticancer immune response.

BACKGROUND: The prognosis of cancer and the efficacy of the various anticancer therapies depend not only on tumor characteristics, but also on the endocrine and immune status of patients. Moreover, studies have shown that the clinical course of the neoplastic disease is also influenced by the psychospiritual status of patients. It is thus probable that the influence of psychospirituality on tumor growth may be mediated by the immunoneuroendocrine system, as demonstrated by the recent advances in psychoneuroendocrinological research. However, at present there are only few data on the possible link between the psychospiritual status and immunoendocrine functions of cancer patients. This study was carried out to investigate the relationships existing among the psychospiritual profile, cortisol rhythm and lymphocyte number before and after chemotherapy, and the efficacy of chemotherapy itself in advanced cancer patients. PATIENTS AND METHODS: The study included 30 consecutive metastatic non-small cell lung cancer patients under chemotherapeutic treatment with cisplatin plus gemcitabine. The psychobiological investigations consisted of lymphocyte count, cortisol circadian rhythm, psychological profile using Rorschach test, and spiritual score, as assessed by a specific clinical test for spirituality. The control group consisted of 100 healthy volunteers. The patients who achieved a tumor regression, showed a significantly higher pre-treatment lymphocyte count and significantly lower alteration of the cortisol rhythm with respect to those who had no benefit from chemotherapy. Moreover, the lymphocyte mean number increased during chemotherapy in responder patients, whereas it progressively diminished in those who had disease progression. Lymphocytopenia and alterations of the cortisol rhythm prior to chemotherapy were associated with a loss of the psychosexual identity according the Rorschach test. Moreover, the mean spiritual score was lower in patients than in controls, although the difference was not significant. Finally, a low spiritual score prior to therapy was associated with a higher frequency of lymphocytopenia and cortisol rhythm alteration, as well as with a lower efficacy of chemotherapy itself. CONCLUSION: This preliminary study would suggest that the psychospiritual status of cancer patients may influence the efficacy of chemotherapy through the immunoneuroendocrine system.

Since experiments regarding a possible relation between olanzapine and orexin A has been scarcely reported in international literature, this experiment tested the effect of olanzapine on the sympathetic and thermogenic effects induced by orexin A. The firing rates of the sympathetic nerves to interscapular brown adipose tissue (IBAT), along with IBAT, colonic temperatures and heart rate were monitored in urethane-anesthetized male Sprague-Dawley rats before an injection of orexin A (1.5 nmol) into the lateral cerebral ventricle and over a period of 150 min after the injection. The same variables were monitored in rats with an intraperitoneal administration of olanzapine (10mg/kg bw), injected 30 min before the orexin administration. The results show that orexin A increases the sympathetic firing rate, IBAT, colonic temperatures and heart rate. This increase is blocked by the injection of olanzapine. These findings indicate that olanzapine affects the complex reactions related to activation of orexinergic system.

AIM: The recent rediscovery of the natural traditional medical sciences has contributed to improve the treatment of the human diseases and, in particular, it has been shown that the pharmacological approach is not the only possible strategy in the treatment of nausea and vomiting, since bioenergetic approaches, such as acupressure and acupuncture, may also counteract the onset of vomiting due to different causes. Previous preliminary clinical studies had already suggested a possible efficacy of acupressure also in the treatment of chemotherapy-induced vomiting resistant to the classical antiemetic drugs. The aim of this study was to confirm these preliminary data. METHODS: The study was performed in 100 consecutive metastatic solid tumour patients, who underwent chemotherapy for their advanced neoplastic disease, and who had no benefit from the standard antiemetic agents, including corticosteroids, antidopaminergics and 5-HT 3R-antagonists. Acupressure was made by a stimulation of PC6 acupoint. RESULTS: The emetic symptomatology was reduced by acupressure in 68/100 (68%) patients, without significant differences in relation to tumour histotype. The lowest efficacy was observed in patients treated by anthracycline-containing regimens, without, however, statistically significant differences with respect to the other chemotherapeutic combinations. CONCLUSION: This study confirms previous preliminary clinical results, which had already suggested the potential efficacy of acupressure in the treatment of vomiting due to cancer chemotherapy. Therefore, acupressure may be successfully included within the therapeutic strategies of cancer chemotherapy-induced vomiting.

AIM: Alopecia still remains one of the most untreatable side-effects induced by cancer chemotherapy. According to the phytotherapeutic tradition, Panicum Miliaceum has been proven to be effective in the prevention of hair loss for different reasons. At present, however, there are no data about its possible efficacy in the treatment of cancer chemotherapy-induce alopecia. The aim of this study was to analyze the efficacy of Panicum Miliaceum in cancer patients treated with the most potent chemotherapeutic drugs in terms of hair loss, consisting of cisplatin (CDDP) and anthracyclines. METHODS: This case-control study included 28 cancer patients concomitantly treated with Panicum Miliaceum and 56 patients receiving the same combinations of chemotherapy alone as a control group. Panicum Miliaceum was given orally at 300 mg (daily dose) 3 times per day, every day until the end of chemotherapy. The grade of hair loss was assessed by World Health Organization (WHO) criteria. RESULTS: The percentage of alopecia of third grade observed in patients concomitantly treated with Panicum Miliaceum in association with CDDP-containing regimens was significantly lower than that found in those who received the chemotherapy only. The percentage was also lower under anthracycline-containing schedules, without, however, statistically significant differences. Panicum Miliaceum therapy was substantially well tolerated in all patients. RESULTS: This preliminary study would suggest that the concomitant treatment with Panicum Miliaceum may be effective in preventing hair loss induced by CDDP-containing chemotherapies, whereas the benefit was lower in patients treated with anthracyclines. Future randomized studies will be necessary to confirm these preliminary

According to recent advances in psychoneuroimmunology concerning the neurobiochemistry of emotions, the pshychological status of cancer patients should be investigated in relation to the function of the psychoneurodocrine system, in an attempt to put into evidence possible cancer progression-related alterations, particularly those involving the dopaminergic pathways, which play a fundamental role in the perception of pleasure. In fact, the decreased capacity of feeling pleasure is one of the most frequent psychic symptoms occurring in cancer patients. Rorschach's test has been proven to be an appropriate psychological tool to investigate psychic condition including sexual and spiritual profiles. On this basis, a study was planned to evaluate if a relation exists between psychological response to Rorschach's test and immunoneuroendocrine status of cancer patients. The immune status was investigated by measuring lymphocyte subsets and serum levels of IL-2 and IL-10. The neuroendocrine status was analyzed by evaluating the endocrine response of PRL, GH and cortisol to an oral administration of apomorphine (0.01 mg/kg b.w.), a dopaminergic agent able to explore dopaminergic sensitivity. The study included 40 cancer patients (breast cancer: 15; colorectal cancer: 14; lung cancer: 11), 21 of whom showed distant organ metastases. Rorschach's test demonstrated a simultaneous suppression of sexual and spiritual profiles in 31/40 (78%) patients, without significant differences in relation to either tumor histotype or disease state. A normal decline in PRL levels and a normal increase in those of GH and cortisol was observed in 29/40 (73%), 5/40 (13%) and 9/40 (23%) patients. The percent of normal responses of PRL, GH and cortisol was higher in patients with normal than in those with altered response to Rorschach's test, even though only the difference in PRL and cortisol response was statistically significant. Patients with normal sexual and spiritual expression at Rorschach's test showed a significantly higher number of total lymphocytes, T lymphocytes, T helper lymphocytes and NK cells with respect to the patients with altered psychological response, whereas no difference was found in T cytotoxic lymphocyte mean number. IL-2 and IL-10 mean serum concentrations were lower and higher, respectively, in patients with altered than in those with normal response to Rorschach's test, even though only the difference in IL-10 values was statitistically significant. This preliminary study, carried out to analyze the psychological status of cancer patients in relation to neuroendocrine and immune conditions, would suggest that neoplastic disease is characterized by a simultaneous suppression of sexual and spiritual profiles, and that this is associated with neuroendocrine alterations and immunosuppression.

The experience of the Cardiac Electrostimulation Center of S. Camillo Hospital in Rome on 1503 patients treated with permanent pacemakers for an 11 year period is referred. The Authors analyze the increase of the activity of the Center during these years and some events that caused it. 94.5% of the patients were more than 50 years old; the dominant pathology has been ischemic and idiopathic cardiopathy, which together include 94.7% of the totality. The indication to the implant has been A-V block in 70% of the patients; intraventricular block in 20%; sick sinus syndrome in 10%. In the last years the prophylactic indication has increased (from 0.4% to 4.4%). 2459 pacemakers have been used, of which 79.5% was QRS-inhibit. The mercury prosthesis have been progressively substituted with the lithium ones. 1642 catheters (implant and reimplant) have been used; principally endocardic (95%) and monopolar (85%). The substitution of the catheter has been necessary in 9% of the totality; in 2.6% of the endocardic and in 15.9% of the epimyocardic. Among 50 electrodes, after a period of observation of about 7.7 years, 36 are still in function. The percentage of the complications has been 17.1%; the most important complications have been: dislocation (6%), microdislocation (1.5%), late high threshold (2.1%), failure of catheter (1.2%), generator malfunction (2.3%). The total mortality has been 15.4%; 0.2% caused by deficit of the implant; 2% sudden deaths and 13.2% not depending from the implant; 243 patients (16%) are not to be found. The frequency of out-patients controls has decreased in the last 2 years (from 3.8 controls per years to 1.8).
