In questo articolo vengono riportate, dopo un breve excursus su inquadramento e trattamento della malattia di Parkinson in medicina occidentale, alcune delle più importanti evidenze sull'efficacia del trattamento con agopuntura in questo ambito. È documentato in letteratura che in questo contesto molti pazienti affetti da Parkinson si rivolgono alle medicine complementari nell'ottica di ottenere dei miglioramenti sintomatologici e di contenere gli effetti avversi della farmacoterapia occidentale. Viene inoltre affrontato l'inquadramento della malattia di Parkinson in Medicina Tradizionale Cinese e i possibili approcci terapeutici.

Radiographic skeletal survey (R-SS) is the standard imaging technique for the initial staging of Langerhans cell histiocytosis (LCH). Whole-body magnetic resonance imaging (WB-MRI) has been proposed as an effective, radiation-free alternative.We prospectively assessed patients with LCH followed at three tertiary centers in Italy and Austria. Two national study protocols were independently designed, and data were then pooled to increase the power of their findings. R-SS and WB-MRI were performed at diagnosis and repeated at the follow-up to confirm the nature of the identified lesions and to study their evolution.Data from 67 patients were analyzed (52 from Italy and 15 from Austria). Compared to R-SS, WB-MRI identified 29 additional skeletal lesions in 14 patients (including two false-positive lesions). Two skeletal lesions were detected at R-SS and missed at WB-MRI (false negative). Per-lesion sensitivity rates were 78.6% (95% CI: 71.0-85.9) for R-SS and 98.4% (95% CI: 94.4-99.8) for WB-MRI, respectively. Based on WB-MRI findings, six patients would have been upstaged to a higher risk class than staging with R-SS.WB-MRI had a significantly higher detection rate for skeletal lesions compared to R-SS. Clinical and radiology expertise is required to avoid upstaging and overtreatment.

Ileocolic intussusception is a common cause of bowel obstruction. When spontaneous reduction does not occur, non-operative management through enema reduction is necessary. Despite the evidence indicating that sedatives favor success in the reduction, their use is still not a common practice. To determine if midazolam (MDZ) before enema improves the rate of procedure success, we retrospectively reviewed charts of patients admitted to two Italian pediatric emergency departments. Outcome measures were the success rate of the enema, recurrence, and need for surgery. Patients were grouped according to the use of MDZ or not, before hydrostatic reduction attempt. We included 69 and 37 patients in the MDZ and non-MDZ groups, respectively. The two groups did not differ in demographics, clinical characteristics, and ultrasound findings. Intussusception reduction after the first enema attempt occurred in 75% (MDZ group) and 32.4% (non-MDZ group) of patients (P .001); 27.9% (MDZ group) and 77.8% (non-MDZ group) of patients underwent surgery (P .001). Among them, spontaneous reduction of intussusception during the induction of general anesthesia occurred in 31.6% and 42.9% of patients, respectively (P .43). Multivariate logistic regression analysis showed that only MDZ had a positive effect on the result of the enema (OR 7.602, 95%CI 2.669-21.652, P .001).Procedural sedation with MDZ for enema reduction of intussusception can increase the success rate and lead to a better management of patients.• Despite the evidence of the usefulness of sedatives in the reduction of intussusception, their use is still not a common practice.• Midazolam during enema reduction of intussusception can increase the success rate and consequently lead to better management of patients.

On March 11th, 2020, the World Health Organization declared COVID-19 infection as a pandemic. Since it is a novel virus, there are basically no proven drugs or therapies; although many laboratories in different countries are working to develop a vaccine, it will take time to make it available. Passive immunization is the therapy born from the intuition of Behring and Kisato in the late 19th century. It was widely used for the treatment of bacterial infections until the discovery of antibiotics, as well as during the viral pandemics of the 20th century and of the beginning of the 21st; it still has clinical applications (e.g., tetanus prevention). This paper summarizes the basic principles of passive immunization, with particular reference to convalescent plasma. The literature concerning its use during past epidemics and the results of the first clinical studies concerning its use during the current pandemic are discussed too. A large section is dedicated to the analysis of the possible, although rare, side effects. Recently, in 2017, the WHO Blood Regulators Network (BRN) published a position paper, recommending convalescent plasma as the first-choice treatment to be tested in the absence of authorized drugs; however, this strategy has not been followed. In the current epidemic, the principle of passive immunization through convalescent plasma has been applied in several circumstances and particularly in patients with serious complications. The first reported results are encouraging and confirm the effectiveness of plasma therapy and its safety. Also, the FDA has proposed plasma treatment in order to face the increasingly complex situation and manage patients with serious or immediately life-threatening COVID-19 disease. Several studies and clinical programs are still ongoing.

Purpose. The prevalence of invasive lobular carcinoma (ILC), the second most common type of breast cancer, accounts for 5%–15% of all invasive breast cancer cases. Its histological feature to spread in rows of single cell layers explains why it often fails to form a palpable lesion and the lack of sensitivity of mammography and ultrasound (US) to detect it. It also has a higher incidence of multifocal, multicentric, and contralateral disease when compared to the other histological subtypes. The clinicopathologic features and outcomes of Invasive Ductolobular Carcinoma (IDLC) are very similar to the ILC. The purpose of our study is to assess the importance of MRI in the preoperative management and staging of patients affected by ILC or IDLC. Materials and Methods. We identified women diagnosed with ILC or IDLC. We selected the patients who had preoperative breast MRI. For each patient we identified the areas of multifocal, multicentric, or contralateral disease not visible to standard exams and detected by preoperative MRI. We analyzed the potential correlation between additional cancer areas and histological cancer markers. Results. Of the 155 women who met our inclusion criteria, 93 (60%) had additional cancer areas detected by MRI. In 61 women, 39,4% of the overall population, the additional cancer areas were confirmed by US/tomosynthesis second look and biopsy. Presurgical MRI staging changed surgical management in the 37,4% of the patients. Only six patients of the overall population needed a reoperation after the initial surgery. No statistically significant correlation was found between MRI overestimation and the presence of histological peritumoral vascular/linfatic invasion. No statistically significant correlation was found between additional cancer areas and histological cancer markers. Conclusions. Our study suggests that MRI is an important tool in the preoperative management and staging of patients affected by lobular or ductolobular invasive carcinoma.

To identify the most frequent radiological findings of pulmonary tuberculosis using CT of the chest, to determine those with the highest degree of correlation, and, if possible, to identify the most suggestive radiological findings for acid-fast bacilli (AFB) positive disease. The radiological and clinical data of 49 patients submitted to CT during diagnosis were retrospectively analysed. The association between findings was assessed using Fisher’s exact test, while correlation at CT scan was evaluated with the Spearman analysis. Bronchiectasis/bronchioloectasis (89.8%), nodule(s) (81.6%), tree-in-bud (TIB), and consolidation (79.6% each) figured among the most common parenchymal findings. Lymphadenopathy (26.5%) was the most common nodal finding. TIB and cavity showed the highest correlation (r = 0.577), followed by TIB and bronchi(olo)ectasis (r = 0.498), TIB and consolidation (r = 0.497), nodule(s), and ground glass opacity (r = 0.488). High correlation was found in only the seven most frequent parenchymal findings. Consolidation, TIB, and cavity were useful to predict the AFB stain positivity. Our series confirms the extreme heterogeneity of pulmonary tuberculosis. It also proves there are couple of findings which can drive us to the right diagnosis. While a triad of findings predicts AFB positivity, we have not found any predictive sign of AFB negativity; consequently, all patients with suspected imaging and clinical findings for TB should be isolated.

Aims and objectives: According to the European directive 2013/59/Euratom, starting from February 2018, the information relating to patient exposure will be part of computed tomography (CT) reports, but the impact of this information on patients has not been deeply evaluated. Aim of our study was to evaluate patients’ perception of radiation exposure related to routine CT and their understanding after communication of their dose exposure. Materials and methods: A survey, investigating patient’s knowledge of radiation dose, was given to all adult patients (> 18 years) undergoing a CT examination both before and after CT scan. The first survey was the same for all patients. After CT scan, a second questionnaire was administered (after receiving the CT dose bill report and medical written and/or explanation about ionizing radiation risk). Results of the pre- and post-CT questionnaires responses were compared according to demographics characteristics and among the four post-CT groups. Results: For some questions, statistically significant differences were found between the two centres. Seventy per cent of the patients answered that the presence of CT parameters in the report is considered useful. Even if not always statistically significant there was a slight increase in awareness of ionizing radiation risk comparing the pre- and post-CT surveys. The group that had both written and oral explanations had a better comprehension of CT dose bill (group III vs. I, p = 0.002). Conclusion: The way of communication of ionizing radiation risks did not affect the results of the post-CT survey. Indeed, the interest in the topic did not rise in the post-CT survey in any of the group. Adequate information about ionizing radiation risks provided together with dose exposure information may be useful. However, there is not a standardized better way of communicating information on ionizing radiation risks due to CT.

Contrast-enhanced digital mammography (CEDM) of the breast is evolving into an important adjunctive tool in breast imaging with increasing indications for its use. However, it does come with its share of limitations. Because it involves the use of contrast media, the factors related to contrast examinations such as allergic reactions and patients contraindicated to contrast media need to be considered prior to the examination. Another important consideration includes radiation exposure; therefore a proper protocol to ensure that the appropriate patients are being studied is necessary.

Introduction Goldenhar syndrome is a rare disease with hemifacial microsomia and craniofacial disorders originating from the first and second branchial arches, such as ocular, auricular, and vertebral anomalies. The complexity and variety of the ways in which the disease presents itself usually need several examinations. In this study, we aimed to evaluate both craniofacial and vertebral skeletal anomalies and asymmetries between the nonaffected and affected sides in patients with Goldenhar syndrome by using cone-beam computed tomography. Methods Ten patients (7-14 years old; 6 boys, 4 girls) were evaluated via NewTom 5G cone-beam computed tomography (QR srl, Verona, Italy) with a large field of view (18 × 16 cm). Ten anatomic facial landmarks were identified to measure the following distances bilaterally: sella turcica (ST)-mandibular angle, ST-condyle, ST-mastoid, ST-mental foramen, ST-fronto zygomatic suture, ST-zygomatic temporal suture, ST-zygomatic facial foramen, ST-sphenopalatine fossa, mandibular angle-mandibular symphysis, and mandibular angle-condyle. The following 6 volumes were calculated bilaterally: orbit, maxillary sinus, condyle, external ear canal, middle ear, and internal auditory canal. These measurements were performed to assess skeletal asymmetries to compare the nonaffected side with the affected side by the Wilcoxon test. Cervical spine anomalies were classified into fusion anomalies and posterior arch deficiencies. Results All patients showed a deficit of skeletal development on the affected side. Statistically significant differences (0.001 ≤ P value ≤ 0.043) between the nonaffected and affected sides were recorded for all measurements, except for ST-frontozygomatic suture, mandibular angle-mandibular symphysis, and maxillary sinus volume. Vertebral fusion anomalies and posterior arch deficiencies were found in 7 and 4 patients, respectively. Conclusions Cone-beam computed tomography with a large field of view was able to accurately identify craniofacial and vertebral skeletal anomalies, and to quantify asymmetries between the nonaffected and affected sides for an efficient maxillofacial treatment planning.

Primary breast lymphoma (PBL) may mimic carcinoma clinically and also mammographic and ecographic distinction is subtle. Despite its rarity, incidence of PBLs has increased over the last four decades and continues to increase for younger women and for some subtypes, and for this reason it is increasingly important to achieve a preoperative pathological diagnosis using core needle biopsy (CNB) or fine-needle aspiration cytology (FNA). The aim of this retrospective study was to report our single-center experience in CNBs performed for histological diagnosis of PBL compared to FNA. From a total of 10,500 CNBs we found seven patients affected by PBL diagnosed at Careggi Florence University Hospital, between January 2000 and December 2016. Diffuse large B cell lymphoma (DLBCL) was the most frequent PBLs and on CNBs specimens was possible do the fluorescent in situ hybridization analysis to evaluate the presence of chromosomal translocation. CNB is an effective method for the assessment of PBLs, especially for DLBCL, in which a correct and fast classification could change the therapeutic approach and the prognosis.

Malondialdehyde (MDA), a biomarker of lipid peroxidation and oxidative stress, is a mutagenic and carcinogenic compound that can react with DNA to form several types of DNA adducts including the deoxyguanosine adduct (M1dG). The aim of this cross-sectional study was to evaluate the association between individual dietary and lifestyle habits and M1dG levels, measured in peripheral leukocytes in a large representative sample of the general population of Florence City (Italy). Selected anthropometric measurements, detailed information on dietary and lifestyle habits and blood samples were available for 313 adults of the Florence City Sample enrolled in the frame of European Prospective Investigation into Cancer and nutrition (EPIC) study. A multivariate regression analysis adjusted for selected individual characteristics possibly related to M1dG levels (sex, age, BMI, smoke, physical activity level, education level, total caloric intake and a Mediterranean dietary score) was performed to estimate the association between these parameters and M1dG levels. M1dG levels were significantly higher in women (P = 0.014) and lower in moderately active or active subjects (P = 0.037).We also found a significant inverse association with the Modified Mediterranean dietary score (P for trend = 0.049), particularly evident for the highest categories of adherence. Our results indicate that M1dG levels can be modulated by selected individual characteristics such as gender, physical activity and a Mediterranean dietary pattern.
