Objectives: To assess evaluability and diagnostic accuracy of a low dose CT angiography (CTA) protocol for carotid arteries using latest Iterative Reconstruction (IR) algorithm in comparison with standard 100 kVp protocol using previous generation CT and IR. Materials and methods: 105 patients, referred for CTA of the carotid arteries were prospectively enrolled in our study and underwent CTA with 80 kVp and latest IR algorithm (group 1). Data were retrospectively compared with 100 consecutive patients with similar examination indications that had previously undergone CTA of carotid arteries with a standard 100 kVp protocol and a first generation IR algorithm (group 2). Image quality was evaluated with a 4-point Likert-scale. For each exam CT number, image noise, signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR) at level of common carotid artery (CCA), internal carotid artery (ICA) and at level of Circle of Willis and Effective Dose (ED) were evaluated. 62 Group 1 patients underwent a clinically indicated DSA and results were compared with CTA. Results: No exams reported as not diagnostic. The overall mean CT number value of all arterial segments was above 450 HU in both groups. Significant lower noise, and higher SNR and CNR values were found in group 1 in comparison with group 2 despite the use of 80 kVp. In 62-group 1 patients studied by DSA, CTA showed in a segment-based analysis a sensitivity, negative predictive value and accuracy of 100%, 100% and 99% respectively. Mean ED in group 1 was 0.54 ± 0.1 mSv with a dose reduction up to 86%. Conclusions: CTA for carotid arteries using latest IR algorithm allows to perform exams with submillisievert radiation exposure maintaining good image quality, overall evaluability and diagnostic accuracy.

Hernia repair is the most common surgical procedure in general surgery in Italy and in the Lombardy region. In the last decade, the use of mesh, the concept of a tension-free technique, and the postoperative rate of recurrences after Bassini or Shouldice operations have completely changed the surgical approach to hernia repair. For this reason, we sent a questionnaire to 148 surgical departments in the Lombardy region to investigate about total hernia operations performed in 2000 in Lombardy, the surgical approach, the surgical techniques used, the type of anesthesia and the hospital stay. One hundred five out of 148 surgical departments returned the questionnaire, and we collected information on a total of 16,935 surgical operations for hernia: 16,494 were performed using tension-free techniques. The inguinal anterior approach is the one of choice for primary and recurrent inguinal hernia, whereas the open preperitoneal and laparoscopic approaches are limited to bilateral and recurrent hernias. The majority of cases were treated under locoregional anesthesia and with a hospital stay of two nights.

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 insomniac. 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.

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

AIM: Corticosteroids, antidopaminergig agents and 5-HT3 antagonists are the most commonly used drugs in the treatment of chemotherapy-induced vomiting. Acupuncture and acupressure have also appeared to exert antiemetic effects. The aim of this study was to evaluate the efficacy of acupressure in the treatment of chemotherapy-induced vomiting resistant to the standard antiemetic therapies. METHODS: The study included 40 consecutive advanced cancer patients with untreatable chemotherapy-induced vomiting. Colorectal cancer, lung cancer and breast cancer were the neoplasm most frequent in our patients. According to tumour histotype, patients received chemotherapeutic regimens containing the main emetic cytotoxic agents, including cisplatin and athracyclines. Acupressure was made by PC6 point stimulation for at least 6 h/day at the onset of chemotherapy. RESULTS: The therapeutic approach was well accepted by the overall patients. An evident improvement in the emetic symptomatology was achieved in 28/40 (70%) patients, without significant differences in relation to neither tumor histotype, nor type of chemotherapeutic agent. CONCLUSIONS: This preliminary study seems to suggest that a bioenergetic approach by acupressure on PC6 point may be effective in the treatment of chemotherapy-induced vomiting resistant to the conventional pharmacological strategies, as previously demonstrated for vomiting occurring during pregnancy
