Intrathoracic anastomotic leakage is one of the major complications of esophageal surgery that can lead to high mortality rate. Depending on the clinical presentation, therapeutic options include surgical reintervention and conservative management with or without external drainage or stenting. In this paper, we report a series of three patients, two men and one woman, mean age of 55.6 years (range 34-68 years), having intrathoracic anastomotic leak after esophagogastrectomy treated by insertion of four covered self-expandable metal stents performed exclusively under fluoroscopic view. Complete resolution of the leakage was obtained in all patients. Despite the limited number of patients, conservative management of intrathoracic anastomotic leaks with covered self-expandable metal stents performed under fluoroscopic guidance has proved to be rapid, safe, and effective in all cases of this series.

We report the case of a 27-year-old woman with primary actinomycosis of the breast. Diagnosis was established by culture examination of specimen recovered by fine-needle aspiration cytology (FNAC) under ultrasound guidance. To our knowledge, this is the first description in the literature of a case of primary actinomycosis of the breast caused byActinomyces viscosus. Twenty-nine previous cases of primary actinomycosis of the breast have been published, but these were caused by the more common speciesActinomyces israelii. Targeted antibiotic therapy did not ameliorate the condition, thus drainage and excision of the mass were carried out. No other medical therapy was administered. Six years after surgery, no recurrence has been observed on both ultrasonographic and mammographic examinations. [ABSTRACT FROM AUTHOR]

Purpose: The aim of this methods work is to explore the different behavior of radiomic features resulting by using or not the contrast medium in chest CT imaging of non-small cell lung cancer., Methods: Chest CT scans, unenhanced and contrast-enhanced, of 17 patients were selected from images collected as part of the staging process. The major T1-T3 lesion was contoured through a semi-automatic approach. These lesions formed the lesion phantoms to study features behavior. The stability of 94 features of the 3D-Slicer package Radiomics was analyzed. Feature discrimination power was quantified by means of Gini's coefficient. Correlation between distance matrices was evaluated through Mantel statistic. Heatmap, cluster and silhouette plots were applied to find well-structured partitions of lesions., Results: The Gini's coefficient evidenced a low discrimination power, <0.05, for four features and a large discrimination power, around 0.8, for five features. About 90% of features was affected by the contrast medium, masking tumor lesions variability; thirteen features only were found stable. On 8178 combinations of stable features, only one group of four features produced the same partition of lesions with the silhouette width greater than 0.51, both on unenhanced and contrast-enhanced images., Conclusions: Gini's coefficient highlighted the features discrimination power in both CT series. Many features were sensitive to the use of the contrast medium, masking the lesions intrinsic variability. Four stable features produced, on both series, the same partition of cancer lesions with reasonable structure; this may merit being objects of further validation studies and interpretative investigations., (Copyright © 2021 Associazione Italiana di Fisica Medica.

Objective: This study was undertaken to model the biochemical free survival at 5 years and to evaluate the parameters defining dose-response curve, dose-fractionation radiosensitivity and repopulation., Methods: It was carried out a literature search on Pubmed to retrieve data sets of patients treated with external beam radiation therapy of 1.8-4.0 Gy per fraction and overall treatment time of 3 to 10 weeks. 10 groups were identified, based on risk class and androgen deprivation therapy (ADT). Dose-response curve D 50 (dose at 50% probability of control) and g 50 (steepness), α/β (dose-fractionation radiosensitivity), and repopulation parameters, d prolif and T prolif , were calculated. Bootstrap-based cross-validation was performed and median and 95% CI (confidence interval) were evaluated., Results: 25 data sets, including 20,310 patients, were considered. The median (95% CI) D 50 and g 50 values were 62 (CI 53 - 66) Gy and 1.6 (0.8 - 2.4). ADT patients showed lower values of D 50 and g 50 (57 ± 5 Gy and 1.1 ± 0.4) compared to no-ADT patients (65 ± 2 Gy and 2.3 ± 0.6), with p < 0.0001 and p = 0.002. If we did not consider any dependence on overall treatment time, the median (95% CI) value of α/β was 1.4 (1.0 - 1.9) Gy with p < 0.0001 for all patients. The median values of d proli f and T prolif were 0.0 to 0.3 Gy/d and 18-40 days., Conclusion: Dose-response curve resulted dependent on risk class and ADT, with higher steepness for no-ADT patients. Low values of dose-fractionation radiosensitivity were found, supporting the use of moderate hypofractionated radiotherapy in each risk class. A limited dependence on repopulation was observed., Advances in Knowledge: Prostate cancer response to moderate hypofractionated radiotherapy was reliably quantified considering risk class and androgen deprivation therapy.

Background: Microwave ablation (MWA) is an emerging treatment for treatment of patients with hepatocellular carcinoma (HCC) not amenable of surgical resection., Patients and Methods: We searched for patients diagnosed as having small-, medium-, and large HCCs treated with MWA under CT guidance between 2010 and 2014. The main outcomes of interest were rates of complete ablation, complications, and overall survival. Rates of complete ablation were compared with Chi-square test, and estimated survival rates were calculated by means of Kaplan-Meier method., Results: Thirty-two patients with 45 HCC nodules received MWA. Seventeen (37.8%) nodules were <3 cm (small), 15 (33.3%) between 3 and 5 cm (medium), and 13 (28.9%) > 5 cm (large). Complete ablation was obtained in 94.1% of small tumors, 80% of medium tumors, and 53.8% of large tumors (p = 0.03). Two patients had HCC located in risk area (paracardiac position). Minor complications occurred after seven procedures (15.5%). Estimated median survival was 37 months (95% confidence interval 11.97-62.02). One-year OS was 82.7%, 2-year survival 68.9%, and 3-year survival 55.2%., Conclusion: MWA is a versatile ablative method that can be applied in HCC at various stages, and also in lesions located in risk areas.

Introduction: The Enterobacter cloacae is a microorganism found in the intestinal flora of the majority of animals, including humans. Primary infections caused by E. cloacae are rare in immunocompetent patients, but are very common in hospital settings in newborns and immunocompromised patients, and can be aggravated by the insurgence of antibiotic resistance. The incidence of periprosthetic hip infections is just below 2%., Case Presentation: A 76year old woman with multiple comorbidities underwent surgical implantation of intermediary total hip prosthesis of the left hip, in a different health facility, in February 2014, after the basicervical fracture of the upper femur extremity due to trauma. After an episode of dislocation of the prosthetic implant, in September 2014, she underwent a surgical operation to implant the acetabular component. A month later not in our facility, following a re-hospitalization for the dislocation of the arthroprosthesis, an infection from E. cloacae complex was discovered. After 2 years of chronic infection she came to our attention; the clinical picture featured coxalgia and secreting fistula in the surgical wound. Following a specific antibiotic therapy, carried out intravenously over the course of a month, we decided to intervene removing the left hip arthroprosthesis and placing an antibiotic spacer following the direction deduced from the antibiogram study of August 2016., Conclusion: The patient was hospitalized in our facility and 2 months later she underwent another operation to remove the antibiotic spacer and to place a new total hip arthroprosthesis. Multiple swabs showed the complete healing from the infection, which was confirmed a couple of months later., (Copyright © 2017 The Authors. Published by Elsevier Ltd.. All rights reserved.)

Purpose of Investigation: to assess the radiological findings of women undergoing hysterosalpingography (HSG) as initial infertility investigation protocol., Materials and Methods: A retrospective study on infertile women who underwent HSG at Institute of Radiology of Sassari University, Italy., Results: The present case series included 2,845 HSG, performed from January 1997 to March 2014. The age of the patients ranged from 20 to 48 years. The negative exams (tubal patency) were 2,039 out of 2,845 (71.67%)., Conclusion: A technique of diagnostic imaging for the evaluation of infertility should be non-invasive, not expensive, rapid, of simple execution, and also be able to provide information on tubal patency and pelvic diseases. For these reasons, HSG today remains a useful diagnostic investigation tool in the diagnostic work-up of infertile patients.

Purpose: To assess retrospectively the safety and feasibility of palliative breast cryoablation to treat primary breast tumors in patients with stage IV breast cancer., Materials and Methods: In 17 female patients (mean age ± SD, 59 y ± 13; range, 37-81 y) with 22 bone metastatic ductal invasive breast lesions (2.5 cm × 1.6 cm ± 1.4 × 1.1; range, 1.0 cm × 0.5 cm to 6.7 cm × 5.5 cm), 19 computed tomography (CT)-guided percutaneous cryoablation sessions were performed for treatment of primary breast tumors. All patients had radiologic evidence (contrast-enhanced CT or magnetic resonance imaging) of persistence or progression of the primary breast cancer despite systemic therapy. The radiologic outcome was evaluated with a mean follow-up period of 13 months (range, 3-31 mo). Treatment of skeletal metastases was unnecessary during the follow-up period., Results: All of the cryoablation sessions were completed and well tolerated. Complete regression of the disease was achieved in 15 (88%) patients 2 months after the cryoablation. Two (12%) patients underwent a second cryoablation treatment because of a minimal persistence of viable tumor (residual disease). No relapse of primary tumors was observed on breast imaging during the follow-up period. One patient (6%) developed a new lesion localized to the contralateral breast., Conclusions: These data suggest that palliative cryoablation of primary advanced breast cancer is a well-tolerated, feasible, and effective treatment option. Given the palliative effects of breast cryoablation demonstrated in this series, larger studies replicating these results are warranted., (Copyright © 2014 SIR. Published by Elsevier Inc.

Background: The role of magnetic resonance imaging (MRI) in newly detected breast cancer remains controversial. We investigated the impact of preoperative MRI on surgical management of infiltrating breast carcinoma (IBC)., Methods: We reviewed data of 237 patients with IBC who were suitable for breast-conserving surgery (BCS) between 2009 and 2011. Of these patients, 109 underwent preoperative MRI (46%; MRI group) and 128 did not (54%; no-MRI group). We analyzed MRI-triggered changes in surgical plan and compared differences in rates of positive margins and mastectomy., Results: Tumor size was larger in the MRI group (16.8 mm vs. 13.9 mm; P < .001). MRI changed the initial surgical planning in 18 of 109 patients (16.5%) because of detection of larger tumor diameter requiring wider resection (8 patients [7.3%]) or additional malignant lesions in the ipsilateral (9 patients [8.2%]) or contralateral breast (1 patient [0.9%]). MRI-triggered treatment changes included mastectomy (n = 12), wider excision (n = 5), and contralateral BCS (n = 1). Reoperation rates for positive margins after BCS appeared higher in the no-MRI group (4.1% vs. 8.6%), but the difference missed statistical significance (P = .9). Overall mastectomy rates were higher in the MRI group (13.7% vs. 7.0%; P < .05). The likelihood of having a change of treatment resulting from MRI was significantly higher for patients with tumors > 15 mm and for those with positive lymph nodes., Conclusion: Lymph node positivity and tumor size > 15 mm may predict an MRI-triggered change in surgical plan. Preoperative MRI resulted in higher mastectomy rates justified by biopsy-proven additional foci of carcinoma and did not significantly reduce reoperation rates for positive margins., (Copyright © 2014 Elsevier Inc.

Purpose: To assess the effects of the combination of pelvic floor rehabilitation, intravaginal estriol and Lactobacillus acidophli administration on stress urinary incontinence (SUI), urogenital atrophy and recurrent urinary tract infections in postmenopausal women., Methods: 136 postmenopausal women with urogenital aging symptoms were enrolled in this prospective randomized study., Patients: randomly divided into two groups and each group consisted of 68 women., Interventions: Subjects in the triple therapy (group I) received 1 intravaginal ovule containing 30 mcg estriol and Lactobacilli acidophili (50 mg lyophilisate containing at least 100 million live bacteria) such as once daily for 2 weeks and then two ovules once weekly for a total of 6 months as maintenance therapy plus pelvic floor rehabilitation. Subjects in the group II received one intravaginal estriol ovule (1 mg) plus pelvic floor rehabilitation in a similar regimen., Mean Outcome Measures: We evaluated urogenital symptomatology, urine cultures, colposcopic findings, urethral cytologic findings, urethral pressure profiles and urethrocystometry before, as well as after 6 months of treatment., Results: After therapy, the symptoms and signs of urogenital atrophy significantly improved in both groups. 45/59 (76.27%) of the group I and 26/63 (41.27%) of the group II referred a subjective improvement of their incontinence. In the patients treated by triple therapy with lactobacilli, estriol plus pelvic floor rehabilitation, we observed significant improvements of colposcopic findings, and there were statistically significant increases in mean maximum urethral pressure, in mean urethral closure pressure, as well as in the abdominal pressure transmission ratio to the proximal urethra., Conclusions: Our results showed that triple therapy with L. acidophili, estriol plus pelvic floor rehabilitation was effective and should be considered as first-line treatment for symptoms of urogenital aging in postmenopausal women.

Purpose of Investigation: To show management of patients with breast lobular carcinoma in situ (LCIS)., Materials and Methods: This study is the retrospective review of 65 patients, between 1996 and 2012, with isolated LCIS of the breast, evaluated through clinical examination, ultrasound, and mammography at the first examination and follow-up., Results: In 53 patients (81.54%), clinical examination was negative. In 14/65 (21.54%) cases, ultrasound was positive and led to biopsy. The clusters of tiny calcifications were the predominant mammographic pattern (45 cases, 69.23%). Forty-six patients (70.77%) underwent surgical biopsy after guided stereotactic placement of metallic marker (hook-wire), 12 (18.46%) by stereotactic vacuum biopsy (SVB), 5 (7.69%) by core needle biopsy (CNB) under ultrasound guidance, two (3.08%) patients CNB with clinically palpable nodules. Fourteen (21.54%) women underwent a quadrantectomy or total mastectomy after the first diagnosis; in this latter group follow-up was negative. Among the 51 patients (78.46%) who did not undergo quadrantectomy or total mastectomy, five relapses occurred, respectively, three LCIS and two infiltrating ductal carcinomas (IDC). Follow-up ranged from 12 to 144 months., Conclusion: LCIS is a risk factor for invasive carcinoma and should be managed with careful follow-up, but if there is a discrepancy between pathology and imaging, surgical excision is mandatory.

Purpose: To retrospectively evaluate the feasibility and efficacy of computed tomography (CT)-guided radiofrequency thermal ablation (RFA) in reducing the pain in patients with painful pelvic recurrence of rectal cancer ineligible for surgical resection., Material and Methods: Twelve consecutive patients (10 men and 2 women; mean age 67 ± 10 years) with painful pelvic recurrence of rectal cancer underwent CT-guided RFA treatments under conscious sedation. At baseline, in all patients pelvic-sacral pain was classified as severe by Visual Analog Scale (VAS; VAS score ≥75 mm). The tumor density and carcinoembryionic antigen (CEA) serum level averages were 46 ± 7 HU and 15.7 ± 9.3 ng/mL, respectively. Clinical outcome was evaluated by VAS with a mean follow-up period of 23 months., Results: All RFA sessions were completed and well tolerated. Morbidity consisted of recto-vesical fistula (8 %) and rectal abscess (8 %). 1 month after RFA procedure, complete lack of enhancement was obtained in 7 cases (58 %). A significant difference in HU and CEA serum level averages between baseline and 1 month post-RFA was revealed (p < 0.000 and p < 0.002, respectively). A significant reduction in pain was obtained: VAS score was significantly different between baseline and the clinical evaluations at week 1 and month 3, 6, 12, and 22) (p < 0.000). At the end of follow-up, 11 patients (92 %) were symptom free., Conclusions: CT-guided RFA of painful pelvic recurrence of rectal cancer can be considered as a feasible and effective treatment for reducing the pain in selected cases.

Background: The use of Macrolane™ seems to have several advantages compared to the other standard methods for breast augmentation: it is faster, less invasive, and requires only local anesthesia. Nevertheless, various complications associated with the use of Macrolane™ have been described, e.g., encapsulated lumps in breast tissue, infection, and parenchymal fibrosis. We report the results of our case series study on the clinical and imaging evaluations of patients who came to our attention after breast augmentation with Macrolane™ injection and evaluate the effect of this treatment on breast cancer screening procedures., Methods: Between September 2009 and July 2010, seven patients, treated elsewhere with intramammary Macrolane™ injection for cosmetic purposes, presented to our institution complaining of breast pain. In all patients, Macrolane™ had been injected under local anesthesia in the retromammary space through a surgical cannula., Results: On mammography, nodules appeared as gross lobulated radiopacities with polycyclic contours. On breast ultrasound, the nodules showed hypo-anaechogenic cystlike features. In all cases, image analysis by the radiologist was hindered by the presence of the implanted substance, which did not allow the complete inspection of the whole breast tissue., Conclusions: From our experience, although safe in other areas, injection of Macrolane™ into breast tissue cannot be recommended at this time. Our study, along with other reports, supports the need to start a clinical trial on the use of injectable fillers in the breast to validate their safety and effectiveness., Level of Evidence Iv: This journal requires that authors assign a level of evidence to each article.

Background. The breech extraction of the fetus through the vagina has a greater risk of hip fracture compared with the extraction by abdominal route. Case. A 2390 g female infant was delivered at 39 weeks by elective cesarean section for breech presentation. The newborn sustained a fracture of the right femur. A simple immobilization of the limb in extension led to a complete healing of the fracture without sequelae. Conclusion. Caesarean delivery reduces the risk of causing a traumatic injury of the newborn compared to vaginal delivery, especially with breech presentation but does not eliminate this possible accidental complication.

Objective: The aim of this study was to design, deliver and evaluate an e-learning teaching programme for post-graduate radiodiagnostics training that would involve various post-graduate schools throughout Italy., Materials and Methods: All of the Directors of Italian post-graduate schools of radiodiagnostics were sent an e-mail on 27 September 2010 informing them of our willingness to set up an e-learning project for the academic year 2010-2011 in the form of single-subject teaching seminars. The proposed subjects were the semeiotics of the various organs and apparatuses in the context of "Urgent/Emergency Pathology". After having received registrations, a calendar of lessons was planned to be held between 10 November 2010 and 12 October 2011. The validity of the project was tested by means of a multiple-choice questionnaire covering the technical and didactic quality of the entire project, to be completed by the students., Results: Fifty-one percent of the universities in Italy participated in the project: Trieste, Udine, Verona, Milan-Bicocca, Novara, Varese, Genoa, Sassari, Rome Campus, the Catholic University of Rome, Chieti, Foggia, Catania, Modena, Florence, Palermo, Bologna, Pavia, Parma and Ferrara. The lessons were attended by a total of 10,261 post-graduate medical students, for an average of 513.1 students per lesson. Seventy percent of the students judged the didactic content "excellent", 25% "good", and 5% "satisfactory"; none said it was unsatisfactory. In terms of visual quality (particularly the details of the radiological images proposed in the form of slides and/or video clips), 73% judged it "excellent", 20% "good", 6% "satisfactory", and 1% "poor". The audio quality was judged "excellent" by 71%, "good" by 22%, "satisfactory" by 6% and "poor" by 1%. In relation to judgement of audio and video quality, it has to be underlined that this was greatly affected by the hardware/software configuration and the band speed and technology of the Internet connection., Conclusions: Technological evolution is overcoming all barriers, and technology is also having a positive impact on the approach to teaching. Our multicentre teaching experience merits the following considerations: the quality of the teaching product was certified by the students' judgements of its didactic content and the quality of reception; the economic cost of the teaching had a minimal impact on the post-graduate schools (€ 18 per lesson). In terms of breaking down national barriers, it is to be hoped that the coordination and integration of diagnostic imaging e-learning projects, with the participation of post-graduate schools in different European countries, can be developed not only in a spirit of "cultural sharing" and the exchange of teaching experiences., (Copyright © 2012 Elsevier Ireland Ltd.

Understanding the evolution of proliferative breast disease such as atypical hyperplasia and carcinoma in situ is essential for clinical management of women diagnosed with these lesions. Therefore, an animal model that faithfully represents human breast disease in every aspect from spontaneity of dysplasia onset, histopathologic features, and genetics to clinical outcome is needed. Previously, we studied canine spontaneous atypical hyperplasia and ductal carcinoma in situ (low, intermediate, and high grade) and reported their similarities to human lesions in histopathologic and molecular features as well as prevalence. To further validate the resemblance of these lesions to humans, we examined their mammographic and sonographic characteristics in comparison with those of human's as well as the potential of the human Breast Imaging Reporting and Data System (BI-RADS) to predict canine disease. Nonlesional, benign, and malignant mammary glands of dogs presented to Sassari Veterinary Hospital were imaged using mammography and ultrasonography. The images where then analyzed and statistically correlated with histopathologic findings and to their similarities to humans. Our results showed that canine mammary preinvasive lesions, benign, and malignant tumors have mammographic abnormalities, including the presence, pattern, and distribution of macrocalcification and microcalcification, similar to their human counterparts. BI-RADS categorization is an accurate predictor of mammary malignancy in canine, with 90% sensitivity and 82.8% specificity. The similarities of mammographic images and the ability of BI-RADS to predict canine mammary malignances with high specificity and sensitivity further confirm and strengthen the value of dog as a model to study human breast premalignancies for the development of prognostic biomarkers.

Breast conservation is a major goal of cancer treatment. Many different minimally invasive options have been considered such as cryoablation. This technique is the best visualized of all ablation techniques due to the phase change during ice formation. We describe a case of breast cancer with lymph node axillary metastasis treated by CT-guided cryoablation. Cryoablation may have unique benefits for cost-effective outpatient breast cancer therapy using only local anesthesia and/or mild sedation.

Interest is growing in non-invasive diagnostic methods for nails in dermatological pathology. Currently, nail disease diagnosis is based mostly on clinical evaluation; instrumental examination, traditionally, has been performed by magnetic resonance. Ultrasound (US) can be proposed as an easier and more available method for the study of the nail apparatus. In this study, the nail unit normal ultrasound anatomy was investigated to obtain data on adult normal parameters. On 35 healthy volunteers (20 women and 15 men--average age of 27 years) we performed an ultrasonographic study on the nail plate (dorsal and ventral), nail matrix and nail bed of all fingers of the hands using a 18 MHz linear transducer with Esaote Mylab 50. A thick gel layer allowed for appropriate transmission of ultrasound without any additional device. Macroscopic nail features were studied by clinical examination and photographic analysis. The following ultrasound parameters were investigated: nail thickness; nail bed thickness; matrix lenght; matrix-bone distance. Blood flow was studied with the use of colour and power colour Doppler. The nail apparatus echographic anatomy consists in: (a) nail plate, represented by two hyperechoic bands (dorsal and ventral) with an hypoechoic or anechoic space between them; (b) nail bed, represented by an area of dys-homogeneous hypo-echogeneity; (c) nail matrix, represented by a markedly hypoechoic area corresponding to the region under the nail sulcus; (d) ligaments, sometimes well detectable and formed by a specialized connective tissue; and (e) vessels, well evaluable through doppler examination.

Planar scintimammography (SM) acquired with a conventional gamma camera has proved a useful complementary tool to mammography (Mx) in breast cancer (BC) diagnosis, but with unsatisfactory sensitivity in small size carcinomas. In this study we assessed the role of planar SM with a high-resolution dedicated breast camera (DBC) in BC diagnosis, comparing the results with those of Mx.A consecutive series of 145 patients scheduled for biopsy for suspected BC underwent Tc-99m tetrofosmin planar SM using a newly developed DBC. Scintigraphic data were compared with Mx findings and correlated to histology.Histopathologic analysis revealed 165 lesions: 143 malignant and 22 benign. SM detected 139/143 carcinomas (overall sensitivity: 97.2%) and was true negative in 19/22 benign lesions (overall specificity: 86.4%). SM sensitivity was 91% in < or =10-mm carcinomas. SM was more accurate than Mx in 42/145 cases (29%), detecting cancer in 9 patients with Mx indeterminate for dense breasts (8/9 tumors were <10 mm), assessing additional tumor foci (all <10 mm) in 5 points with multifocal disease and correctly classifying 28 patients with inconclusive mammographic findings as affected by cancer or by benign disease. Mx was more accurate than SM in 3 patients, in each detecting 1 subcentimeter BC false negative on SM.DBC planar SM seems a highly sensitive diagnostic tool in the detection of BC, even when small in size, and in the assessment of multifocal disease. A wider employment of this procedure is thus suggested, especially in indeterminate or inconclusive mammographic findings to improve sensitivity and specificity of Mx.

Purpose: The purpose of this study was to examine the effect of periarticular injection of hyaluronate into shoulders with supraspinatus tendinosis under echographic guide., Methods and Materials: The subjects were 56 patients with clinical, echographic and magnetic resonance diagnosis of supraspinatus tendinosis. They were divided in two groups by random sampling; 28 patients were assigned in SH group (sodium hyaluronate) and 28 patients in SC group (sodium chloride). The test drug was 20mg sodium hyaluronate (2ml, Hyalgan, Fidia SpA, Abano T., P.M. 500-700.000, 20mg/2ml)., Results: Preliminary results showed that sodium hyaluronate presented the highest efficacy in the improvement of clinical symptoms and recovery of functional status in patients with supraspinatus tendinosis in fact the mean V.A.S. score (Visual Analogue Scale) at 1 month after the end of the infiltrative cycle was 8.0 in the SC group vs. 2.8 in SH group and these numerical data were substantially unchanged also after 3 and 4 months., Conclusion: Hyaluronate injection under echographic guide should be use not only as a lubricant but also to prevent articular cartilage degeneration and cover and protect the articular cartilage; indeed sodium hyaluronate can decrease inflammatory joint process.

Background: Urgent late complications of biliopancreatic diversion (BPD) are rare and often require the experience of a bariatric surgery team for their immediate resolution., Methods: The present work analyzes the incidence of emergency surgical conditions in a group of 138 patients who had undergone classical BPD, with a mean follow-up of 60 months (24-96) after BPD., Results: Urgent surgical intervention was necessary in 9 patients out of 138 (6.5%): 7 (5%) were for intestinal obstruction (4 of the biliopancreatic limb and 3 of the alimentary tract); 2 (1.4%) were for stomal ulcer with complications (1 massive hemorrhage and 1 perforation)., Conclusions: These complications of BPD are common to all GI operations, and thus are not specific to the type of surgery. We emphasize the importance of early diagnosis and treatment, particularly in regard to intestinal obstruction, because delay could have dramatic consequences.

We describe a case of right axillary lymph node metastasis of an occult infiltrating lobular carcinoma arising from accessory mammary gland of the left upper anterior chest wall. Ultrasonography and mammography were normal bilaterally. Magnetic resonance imaging (MRI) revealed a 3.34 cm inhomogeneous lesion. Then, core biopsy under ultrasound guidance demonstrated a typical infiltrating breast lobular carcinoma. To our knowledge, this is the first case reported in the literature of an axillary lymph node metastasis from an occult contralateral infiltrating lobular carcinoma of the accessory breast tissue. MRI was useful for assessing the lesion of the accessory breast tissue.
