Correction of an end colostomy prolapse with the Delorme technique. A case report.

INTRODUCTION: We report a case of correction of an end colostomy prolapse with Delorme technique in an advanced stage oncologic patient to emphasize the clinical implications and advantages of this procedure. CASE REPORT: A 51-year-old male patient with a stage IV rectal adenocarcinoma underwent laparoscopy for a palliative end colostomy at our institution. Approximately 6 months later, a prolapse of the colostomy occurred during chemotherapeutic treatment. The patient complained of progressive onset of pain and bleeding during defecation as well as difficulty managing the pouch system. Given the stage of the disease and the on-going chemotherapy, a minimally invasive approach was desirable for prolapse correction and we opted for the Delorme procedure under local anesthesia. The postoperative course was excellent with no complications, the symptoms regressed rapidly, and defecation was normal immediately after surgery. The patient was discharged on the second post-operative day. After discharge the stoma was periodically controlled, confirming the success of the procedure. The last clinical evaluation was performed 3 months after surgery and stability was observed. CONCLUSIONS: The Delorme technique is a minimally invasive procedure used to correct an end colostomy prolapse. This technique guarantees excellent results in selected patients and permits the avoidance of more invasive procedures.

Conservative management of minor anastomotic leakage after open elective colorectal surgery.

INTRODUCTION: The utility of prophylactic drainage in colorectal surgery is controversial. The aim of the present article is to study the role of drainage tubes on the management of minor anastomotic dehiscences. PATIENTS AND METHODS: We retrospectively review clinical reports of 18 consecutive patients with anastomotic dehiscence after open elective colorectal surgery. The mean age was 63 years and the male - female ratio was 5:1. Nine (50%) patients underwent re-operation for fecal peritonitis (group A) while the remaining nine (50%) were managed conservatively (group B). The parameters evaluated in both groups were: time of the anastomotic breakdown, clinical findings, amount of fluid drained the day of the dehiscence, diagnostic means used, length of stay and mortality. RESULTS: Anastomotic leakages were observed medially after 3, 6 days from surgery in group A and after 5.6 days in group B. The most frequent clinical manifestations were: fecal material through the tubes (88.9%), pelvic pain (88.9%) and fever (77.8%). Patients in group A had a median faecal fluid flow of 235cc the day of the dehiscence and 130cc those in group B. Imaging was employed only in three cases in group A and in all cases in group B. The length of hospital stay was longer in patients treated surgically: 37 days versus 29 in those treated conservatively. CONCLUSIONS: Minor anastomotic leakages generally occur later than greater ones, they have a milder clinical presentation and can be managed conservatively with the use of drain tubes.

Red Blood Cell Distribution Width (RDW) Correlates to the Anatomical Location of Colorectal Cancer. Implications for Clinical Use.

PURPOSE: The pathological, clinical, and therapeutic features of colorectal cancer (CRC) depend on its anatomical localization. We investigated possible associations between the red blood cell distribution width (RDW) and CRC localization. METHODS: Two-hundred eighty-eight consecutive patients with CRC were retrospectively studied. Demographic, clinical, pathological and laboratory data were retrieved from clinical records and reports. RESULTS: Median RDW values were significantly higher in patients with right-sided CRC when compared to those with CRC in other localizations (16.2, IQR: 14.5-20.0 vs 13.8, IQR: 13.0-16.1, p < 0.0001). Anisocytosis was statistically associated to haemoglobin (Hb), mean haemoglobin concentration (MHC), and mean corpuscular volume (MCV) values in all the patient groups examined. A cut-off value of 14.3% was associated with right-sided localization with sensitivity and specificity of 76.3% and 64.2%, respectively (AUC 0.71). CONCLUSION: Median RDW values were significantly higher in right-sided CRC when compared to other tumour locations, and may represent an additional marker for differential diagnosis.

T2-T4 sympathectomy versus T3-T4 sympathicotomy for palmar and axillary hyperhidrosis.

OBJECTIVE: To evaluate and compare the immediate and long-term outcomes of videothoracoscopic T2-T4 sympathectomy and T3-T4 sympathicotomy for the treatment of palmar and axillary hyperhidrosis. METHODS: Between October 1993 and September 2007, we treated a total of 88 patients affected by palmar and axillary hyperhidrosis. Twenty-four patients underwent T2-T4 sympathectomy with 5-10 mm trocars (Group A), 43 T2-T4 sympathectomy with 2-5 mm trocars (Group B), 15 T3-T4 sympathicotomy with 5-10 mm trocars and 6 T3-T4 ganglion block with 2-5 mm trocars (Group C). The mean operative time, for each side, was 15 min for sympathicotomy and 28 min for sympathectomy. In September 2008, we recontacted 98% of patients (total 86), by telephone, to establish long-term results (follow-up range 1-15 years). RESULTS: In this series, we did not find any significant difference between T2-T4 sympathectomy and T3-T4 sympathicotomy in terms of postsurgical palmar anhidrosis or onset of compensatory hyperhidrosis, while both methods show high efficacy for remission of palmar hyperhidrosis. The slightly higher recurrence rate in our early experience (Group A) can be attributed to the learning curve. Using smaller trocars (2-5 mm), we reduced postsurgical intercostal pain and obtained better aesthetic results and a higher grade of patient's satisfaction. INTERPRETATION: Thoracoscopic approach to hyperhidrosis has evolved in the last few decades with a consequent decrease in side effects. In this series, all patients experienced an improvement in quality of life even in case of recurrence or onset of compensatory hyperhidrosis. Due to these results, the shorter operative time and easier performance of sympathicotomy, we prefer this method.

[IPTH dosage as a prognosis predictor of postoperatory hypocalcemia in patients submitted to total thyroidectomy]. / II dosaggio del iPTH come indicatore prognostico di ipocalcemia postoperatoria nei pazienti sottoposti a tiroidectomia totale.

INTRODUCTION: Hypocalcemia is the most frequent complication after total thyroidectomy (TT) and represents the main cause of prolonged hospital stay because of the need to monitor the calcemic status of the patients. The aim of this study is to evaluate the role of serum iPTH as a predictor of post-thyroidectomy hypocalcemia in order to allow patients' early and safe discharge. MATERIALS AND METHODS: Fifty patients who underwent TT without autotransplantation of parathyroid tissue were prospectively included in the study The mean age was 52 years and the male/female ratio was 1/6. The iPTH serum level were determined 1 hour after the operation and the calcium serum values after 24 and 48 hours. The cut-off value assumed for testing the sensitivity, specificity, PPV and NPV was 16 pg/ml. RESULTS: Nineteen patients (38%) presented hypocalcemia within 48 hours after TT and 16 of them (84.2%) had iPTH serum levels lower than 16 pg/ml. The normocalcemic patients were 31 (62%) and only 4 of them had iPTH serum levels inferior to the cut-off value. Postoperative iPTH serum level determined 1 hour after the operation had a sensibility of 84.2%, specificity of 87.1%, PPV and NPV of 90% and 80% respectively. CONCLUSIONS: The dosage of iPTH serum levels after total thyroidectomy reliably predicts patients who are likely to develop hypocalcaemia. It may be useful in clinical practice in order to reduce the number of postoperative blood tests and the hospital length of stay for the patients who are not at risk of postoperative hypocalcemia.

[Surgical management of a voluminous abdominal paraganglioma and review of the literature]. / Management chirurgico di voluminoso paraganglioma dell'addome. Case report e revisione della letteratura.

UNLABELLED: The Authors report a case of a voluminous abdominal paraganglioma and a review of the literature on the surgical management of paragangliomas. CASE REPORT: A 58 years old woman was admitted to our Institution with acute endocrine impairment and simultaneous intestinal necrosis resulting from the mass effect of the tumor on the mesenteric vessels. Clinical and biochemical preoperative work up posed the suspect of paraganglioma. Previous intensive care treatment, the patient, underwent surgical resection of the tumor and left hemicolectomy, with immediate remission of both endocrine and abdominal syndromes. Histological examination confirm the preoperative clinical hypothesis. Paragangliomas are rare tumors of the extra-adrenal chromaffin tissue. A paraganglioma may be discovered in the absence of any symptom. When symptomatic, the clinical findings are related to the hypersecretion of catecholamines or to the compression of several anatomical structures from a growing mass. Combined acute syndromes of hormonal impairment and contemporaneous mass effect, as in our case, are exceptional. The diagnosis of the secreting forms may be obtained on the basis of biochemical dosage of serum and urinary catecholamines and metanephrines. The assessment of malignancy for paragangliomas is not always feasible. Several imaging, cytological and histological parameters have been proposed as predictors of malignancy, but the only element widely accepted is the existence of distant metastasis. Surgery represents the treatment of choice for paragangliomas. Benign forms, catecholamine secreting forms and tumors compressing neighbouring anatomical structures can be treated surgically with success. In general, an accurate follow-up after complete resection must be considered.

Deregulation of cancer-stem-cell-associated miRNAs in tissues and sera of colorectal cancer patients.

Colorectal cancer (CRC) is a deadly tumour in Western countries characterized by high cellular/molecular heterogeneity. Cancer stem cells (CSC) act in cancer recurrence, drug-resistance and in metastatic epithelial-to-mesenchymal transition. microRNAs (miRNAs) contribute to cancer is increasing, and miRNA roles in CSC phenotype and fate and their utility as CRC biomarkers have also been reported. Here, we investigated miR-21, miR-221, miR-18a, miR-210, miR-31, miR-34a, miR-10b and miR-16 expression in experimental ALDH+ and CD44+/CD326+ colorectal CSCs obtained from the human CRC cell lines HCT-116, HT-29 and T-84. Then, we moved our analysis in cancer tissue (CT), healthy tissue (HT) and serum (S) of adult CRC patients (n=12), determining relationships with clinical parameters (age, sex, metastasis, biochemical serum markers). Specific miRNA patterns were evident in vitro (normal, monolayers and CSCs) and in patients' samples stratified by TNM stage (LOW vs HIGH) or metastasis (Met vs no-Met). miR-21, miR-210, miR-34a upregulation ad miR-16 dowregulation associated with the CSCs phenotype. miR-31b robustly overexpressed in monolayers and CSCs, and in CT ad S of HIGH grade and Met patients, suggesting a role as marker of CRC progression and metastasis. miR-18a upregulated in all cancer models and associated to CSC phenotype, and to metastasis and age in patients. miR-10b downregulated in CT and S of LOW/HIGH grade and no-Met patients. Our results identify miRNAs useful as colorectal CSC biomarker and that miR-21, miR-210, miR-10b and miR-31b are promising markers of CRC. A specific role of miR-18a as metastatic CRC serum biomarker in adult patients was also highlighted.

The Inhibitory Role of miR-486-5p on CSC Phenotype Has Diagnostic and Prognostic Potential in Colorectal Cancer.

Colorectal cancer (CRC) is the third most frequent cancer worldwide and the second cause of cancer deaths. Increasing evidences supports the idea that the poor prognosis of patients is related to the presence of cancer stem cells (CSCs), a cell population able to drive cancer recurrence and metastasis. The deregulation of microRNAs (miRNAs) plays a role in the formation of CSC. We investigated the role of hsa-miR-486-5p (miR-486-5p) in CRC, CSCs, and metastasis, in order to reach a better understanding of the biomolecular and epigenetic mechanisms mir-486-5p-related. The expression of miR-486-5p was investigated in three different matrices from CRC patients and controls and in CSCs obtained from the CRC cell lines HCT-116, HT-29, and T-84. In the human study, miR-486-5p was up-regulated in serum and stool of CRC patients in comparison with healthy controls but down-regulated in tumor tissue when compared with normal mucosa. miR-486-5p was also down-regulated in the sera of metastatic patients. In vitro, miR-486-5p was down-regulated in CSC models and it induced an inhibitory effect on stem factors and oncogenes in the main pathways of CSCs. Our results provide a step forward in understanding the role of mir-486-5p in CRC and CSC, and suggest that further studies are needed to investigate its diagnostic and prognostic power, possibly in combination with other biomarkers.

[The role of cervical mediastinoscopy and video assisted thoracoscopy in the diagnosis and staging of thoraco-mediastinal neoplastic diseases]. / Ruolo della mediastinoscopia e della video toracoscopia per la diagnosi e la stadiazione delle patologie neoplastiche toraco-mediastiniche.

INTRODUCTION: In this work we evaluate the role of mediastinoscopy and video-assisted thoracoscopy in the diagnosis and staging of coin lesion of the lung and of mediastinal masses. MATERIALS AND METHODS: 72 patients, 55 males and 17 females, affected by lung coin lesion without any previous histological diagnosis have been admitted to our Institution from 1997 to 2007. Mean age was 59.4 for males (range 29-82) and 57.2 for females (range 14-79). RESULTS: Mediastinoscopy resulted to be diagnostic in 95% of cases. In just one case mediastinoscopy failed and video assisted thoracoscopy was performed, which permitted to obtain diagnosis. Video assisted thoracoscopy was able to lead to diagnosis in 98.1% of cases, as we observed only one failure. In this single case we converted the thoracoscopic approach to open, but although the conversion it was not possible to make diagnosis. DISCUSSION: In these ten years, thanks to adequate indication for mediastinoscopy and video assisted thoracoscopy, the use of thoracotomy for diagnosis and staging of pulmonary neoplastic diseases has been reduced: thus we avoided 80% of unnecessary thoracotomies in patients affected by not resectable lung cancer, metastases (treated by atypical thoracoscopic resection) or benign diseases. CONCLUSION: The minimally invasive surgical exploration of mediastinum and thoracic cavity allows to obtain all necessary informations (in terms of histology and staging) to programme an adequate therapeutic protocol, reducing postoperative pain and hospital stay, in comparison to thoracotomy.

[Functional sequelae after low anterior rectal surgery]. / Le sequele funzionali dopo chirurgia del retto basso.

INTRODUCTION: The treatment of colorectal cancer has changed radically in the last decades. Due to the great advances it is now often possible to subject patients to oncological radical treatments without applying to highly aggressive surgery, such as the Miles abdomino perineal resection, which requires a definitive colostomy. So nowadays we more and more apply to anterior resection of the rectum. Some recent studies about quality of life in patients who underwent anterior resection of the rectum focalized their attention on postoperative functional sequels. In particular incontinence, constipation, obstructed defecation and urgency are some of the symptoms which define the anterior resection syndrome, which can be efficiently treated by electrostimulation and biofeedback. MATERIALS AND METHODS: A prospective study on 61 patients who underwent between 2002 and 2007 anterior resection of the rectum with total mesorectal excision for adenocarcinoma, has shown symptoms of anterior resection syndrome in 14 patients. Succeeding treatment with sphincter electrostimulation and biofeedback has shown improvement in all patients and complete resolution of the anterior resection syndrome in 10 patients who showed a great compliance and a steady improvement on quality of life. DISCUSSION AND CONCLUSIONS: Rehabilitative treatment with electrostimulation and biofeedback can sensibly reduce symptoms of anterior resection syndrome. An accurate manometric functional assessment is necessary before starting treatment with electrostimulation and biofeedback.

[Surgical treatment of a patient with retrosternal thyroid goiter]. / Trattamento chirurgico del paziente con gozzo tiroideo immerso.

INTRODUCTION: The term thyroid goiter is accepted worldwide, while the terms "substernal", "retrosternal" or "intrathoracic" are not clearly agreed on. The tendency to enlarge and to compress adjacent anatomical structures and the chance of malignancy impose the surgical excision as the principal treatment option. We present our experience on the management of substernal goiter and through this, a rapid review of the literature. MATERIALS AND METHODS: The last seventeen years we treated 94 patients with substernal goiter. The mean age was 57 years and the male - female ratio was 1:5. All patients had preoperatory assessment with chest X ray, ultrasound and CT scan of the neck. We performed a total thyroidectomy through cervical access in 96.7% of cases and in 3.2% through sternotomic access. RESULTS: We found 95.7% cases of anterior and 4.3% cases of posterior goiters, with only one ectopic goiter. Pathologic examination reveal 72.3% colloidocystic goiters, 18% adenomas, 7.4% carcinomas and 2.3% cases of thyroiditis. The most important postoperatory complications were: 2 cases of persistent hypoparathyroidism, 3 cases of recurrent damage and 2 cases of chylothorax. No deaths were observed. CONCLUSIONS: It is necessary a scientific agreement on the definition of substernal goiter, in order to uniform epidemiological and clinical data. Preoperative assessment is based on chest X ray, ultrasound and CT scan of the neck. Cervicotomic access represents the most frequent approach and total thyroidectomy is the procedure recommended. Postoperative complications are almost the same as for cervical goiters and mortality is nowadays extremely low.

[Cystic pancreatic tumor treated by distal spleno-pancreatectomy with occasional diagnosis of neuroendocrine tumor: case report]. / Tumore cistico pancreatico trattato mediante splenopancreasectomia distale con riscontro occasionale di neoplasia neuroendocrina. Case report.

INTRODUCTION: Cystic and neuroendocrine pancreatic neoplasms are quite rare tumors which diagnosis is often difficult due to their non specific symptomatology and limited diagnostic accuracy of conventional diagnostic instruments. Their treatment is still controversial. CASE REPORT: A young woman is admitted with abdominal pain and dyspepsia. Instrumental diagnosis reveals a cystic pancreatic lesion which seems to be malignant as CEA of pancreatic liquid is increased. The patient undergoes distal spleno-pancreatectomy and postoperative histological examination found IPMN associated with MCN and furthermore there was occasional diagnosis of a small neuroendocrine tumor in the pancreatic tail. DISCUSSION: A correct diagnostic approach is indispensable for a correct therapeutic approach. Radical surgical treatment is indicated in all cases of main- and branch duct IPMN and in case of MCN with signs of malignant transformation. Surgical treatment is also the gold standard for pancreatic neuroendocrine tumors if they are singular and in M0 stage. CONCLUSIONS: In case of cystic and neuroendocrine neoplasms of the pancreas the preoperative diagnostic approach is often not enough to obtain a definite diagnosis. Review of literature and this case report show that a definite diagnosis can only be done after postoperative histological examination. Recent prospective studies suggest the possibility for a follow up instead of surgical treatment for some neuroendocrine tumors.

Deciduoid mesothelioma of the thorax: A comprehensive review of the scientific literature.

OBJECTIVE: Deciduoid mesothelioma is a rare variant of malignant epithelioid mesothelioma. It often involves the peritoneum, but also thoracic cases have been reported. The aim of the present review is to describe the demographic, clinical, radiological, and pathological features of such a rare variant of thoracic mesothelioma, and the state of the art regarding the therapeutic approaches currently available. DATA SOURCE: English-language articles published from 1985 to June 2016, and related to thoracic deciduoid mesothelioma cases were retrieved using the Pubmed database. STUDY SELECTION: The search terms were "mesothelioma," "thoracic mesothelioma," "epithelial mesothelioma," "pleural mesothelioma," and "deciduoid mesothelioma." RESULTS: Forty-four cases included in 16 articles, published in the period under investigation, were analyzed in detail. CONCLUSIONS: The mean age of the patients was 63 years, and the male to female ratio 1.7:1. Approximately 58% had exposure to asbestos, and 73% had a smoking history; familiarity was rarely reported. The most common anatomical site of origin was the right pleura, and the most frequent clinical manifestations were chest pain, dyspnea, cough, and weight loss. Thoracic X-ray and computed tomography were the imaging techniques most employed for diagnosis and surgical planning. The pathological diagnosis was obtained by examination of surgical or biopsy specimens in most cases. The best treatment strategy of deciduoid mesothelioma is a matter of debate; nevertheless a multidisciplinary approach is currently the best option for the choice of the adequate therapeutic scheme.

Red cell distribution width and mean platelet volume as predictors of anastomotic dehiscence in colorectal surgery A pilot multicenter case-match study.

AIM: One of the most serious complications in modern colorectal surgery is the occurrence of an anastomotic dehiscence. The aim of this study was to evaluate the role of preoperative red cell distribution width (RDW) and mean platelet volume (MPV) as predictors of anastomotic dehiscence in elective surgery for colorectal cancer. MATERIALS AND METHODS: Forty-two patients with a clinically manifested anastomotic dehiscence after oncological colorectal surgery, and 42 controls matched for age, sex, pathological stage and tumor localization were enrolled. Correlations between the preoperative RDW and MPV values and anastomotic dehiscence were investigated. RESULTS: Both the median RDW value (14.4 % vs 13.1%; p=0.007) and the median MPV value (8.0 fL vs 7.5 fL; p=0.037) were significantly higher in patients with anastomotic dehiscence than in those without. In multiple regression analysis only the RDW remained significantly associated with anastomotic dehiscence. CONCLUSIONS: The preoperative values of RDW may be useful in predicting anastomotic damage in elective oncological surgery. KEY WORDS: Anastomotic Dehiscence, MPV, RDW.

Surgical management of primary and recurrent carcinoma showing thymous-like elements (CASTLE).

INTRODUCTION: Carcinoma showing thymous-like elements (CASTLE) is a rare tumor with only a few cases described in the scientific literature. The aim of the present review is to analyze the data available on the therapeutic options employed in CASTLE tumors and to outline the best surgical management to adopt. MATERIALS AND METHODS: English-language articles published from 1985 through November 2016, and related to CASTLE cases were retrieved using the Pubmed database and specific key-words. RESULTS: Eighty seven cases included in 23 papers, published in the period under investigation, were analyzed in detail. The mean age of the patients was 50.2 years and the male to female ratio 1:1.2. There were performed 31 (35.6%) lobectomies, 29 (33.3%) total thyroidectomies, 15 (17.2%) subtotal thyroidectomies, 4 (4.6%) excisions, 3 (3.4%) partial thyroidectomies, 1 (1.1%) hemithyroidectomy, and 8 (9.2%) additional procedures including tracheal, pharyngeal, and esophageal resections. Lymph node dissection and radiotherapy were associated in 59 (67.8%) and 44 (50.6%) cases respectively. Among the patients with available data 62 (75.6%) were free of disease, 16 (19.5%) were alive with disease, 3 (3.7%) died for the disease, and 1 (1.2%) died for cerebrovascular complications at the time of follow-up. Globally 20 (24.4%) cases of local or distant recurrence were reported. Surgery and radiotherapy, alone or in combination were the treatments most frequently used for recurrences. CONCLUSIONS: CASTLE is a rare tumor which generally respond well to complete surgical resection and adjuvant radiotherapy. These treatments can be further employed for the recurrences, which occur in 24.4% of the cases, along with specific chemotherapy regimens and palliative procedures. KEY WORDS: Cancer, CASTLE, Excision, Lobectomy, Thymous-like elements, Thyroidectomy.

[In situ carcinomas of the breast: clinical features and therapeutic strategies]. / I carcinomi in situ della mammella: inquadramento clinico ed attualità terapeutiche.

INTRODUCTION: Lobular and ductal carcinomas in situ of the breast (LCIS and DCIS) origin from the ductal-lobular unit of mammary gland, but they are characterized for different morphologic patterns and evolution. In 1980 they represent 1.4% of diagnosis in breast biopsy, less of 5% of carcinomas of the breast. Actually in 7.5% of breast biopsy an in situ carcinoma is recognized (approximating 40% of breast cancers). Our purpose is to evaluate the different available strategies in the clinic management of DCIS and LCIS and, in case of surgical treatment, which reconstructive approach obtains satisfactory breast conformation. MATERIALS AND METHODS: The study enclose 125 patients: 40 of them presented LCIS (32%) and 85 DCIS (68%). In 40 patients (32%) underposed to mastectomy was performed a reconstruction in cooperation with aesthetic surgeons. 35 of 40 women with LCIS are included in a follow-up programme, 5 of them had a bilateral mastectomy and reconstruction. RESULTS: No recurrences were observed in patients affected by LCIS. Six patients underposed to wide excision for DCIS developed local recurrence, treated by mastectomy. No recurrences were observed in patients treated initially with mastectomy. Some complications correlated to reconstruction were detected. CONCLUSIONS: One of most controversial sights in breast pathology is the understanding of biological meaning of CLIS: in facts CDIS can be considered a pre-invasive cancer, CLIS is reasonably considerable only a risk indicator for developing breast cancer but it isn't a pre-neoplastic lesion. Very important is the reconstruction of the breast to improve the quality life of patients.

Breast Nodular Fasciitis: A Comprehensive Review.

BACKGROUND: This article describes the demographic, clinical, pathological and prognostic features of breast nodular fasciitis through a comprehensive review of the cases reported in modern literature. MATERIAL AND METHODS: English-language articles published from January 1970 to October 2015 and related to breast nodular fasciitis were non-systematically retrieved using the PubMed database. Titles, abstracts and references were evaluated in order to include the most relevant studies. The demographic characteristics of the patients and the signs and symptoms of the disease were reviewed, as well as the results of the radiological and diagnostic procedures employed and of the treatments adopted. RESULTS: 26 papers reporting on 28 cases were enrolled; however, manuscripts published before 1990 were excluded because of old methodologies, technologies and clinical approaches. Thus, 22 cases included in 20 papers were analyzed in detail. CONCLUSION: The rarity and the unspecific clinical and radiological characteristics of breast nodular fasciitis make the differential diagnosis and management challenging. Knowledge of the clinical, pathological and prognostic aspects of this condition is crucial for breast care specialists in order to improve their diagnostic and therapeutic interventions.

Impact of tissue type and content of neoplastic cells of samples on the quality of epidermal growth factor receptor mutation analysis among patients with lung adenocarcinoma.

Assessment of the epidermal growth factor receptor (EGFR) mutational status has become crucial in recent years in the molecular classification of patients with lung cancer. The impact of the type and quantity of malignant cells of the neoplastic specimen on the quality of mutation analysis remains to be elucidated, and only empirical and sporadic data are available. The aim of the present study was to investigate the impact of tissue type and content of neoplastic cells in the specimen on the quality of EGFR mutation analysis among patients with lung adenocarcinoma. A total of 515 patients with histologically-confirmed disease were included in the present study. Formalin-fixed paraffin embedded tissue samples were used for the mutation analysis and the content of the neoplastic cells was evaluated using light microscopy. Genomic DNA was isolated using a standard protocol. The coding sequences and splice junctions of exons 18, 19 and 21 in the EGFR gene were then screened for mutations by direct automated sequencing. The mean age of the patients examined was 64.9 years and 357 (69.3%) were male. A total of 429 tissue samples (83.3%) were obtained by biopsy and the remaining samples were obtained by surgery. A total of 456 samples (88.5%) were observed from primary lung adenocarcinomas, while 59 (11.5%) were from metastatic lesions. EGFR mutations occurred in 59 cases (11.5%); exon 18 mutations were detected in one case (1.7%), whereas exon 19 and 21 mutations were detected in 30 (51%) and 28 (47.3%) cases, respectively. EGFR mutations were more frequent in females and patients that had never smoked. The distribution of the mutations among primary and metastatic tissues exhibited no significant differences in the proportions of EGFR mutations detected. However, a statistically significant difference in the number of mutations detected was found between samples with at least 50% of neoplastic cells (450 cases-57 mutations; 12.7%) and those with <50% of neoplastic cells (65 cases-2 mutations; 3.1%).

Impact of transthoracic endoscopic sympathectomy on plantar hyperhidrosis.

INTRODUCTION: The aim of this study is to evaluate the impact of transthoracic endoscopic sympathectomy on plantar hyperhidrosis in patients operated on for upper limb hyperhidrosis. MATERIALS AND METHODS: From 2003 to 2011, 41 consecutive patients underwent videothoracoscopic T3-T4 sympathicotomy or T3-T4 ganglion block at our Unit for upper limb hyperhidrosis. Twenty-one (51%) were affected by palmar hyperhidrosis and 20 (49%) by palmar and axillary hyperhidrosis combined. The patients affected by the plantar form were 26 (63%). Clinical follow-up was performed at 3, 6 and 12 months after surgery. Phone interviews and/or clinical assessment were made after a variable period of time (range 6 months to 8 years) to asses long term results. RESULTS: Plantar hyperhidrosis improved in 14 patients, which represents the 54% of the sufferers and the 34% of all patients. It was partially regressed in 11 patients (79%) and resolved in 3 cases (21%). There were not significant differences between patients treated with sympathicotomy and those treated with ganglion block. CONCLUSIONS: Transthoracic endoscopic sympathectomy performed through T3-T4 sympathicotomy or ganglion block improves plantar hyperhidrosis in approximately 54% of the affected patients, with a partial and complete resolution rate of 79% and 21% respectively.

Epidemiology of malignant pleural mesothelioma in the province of Sassari (Sardinia, Italy). A population-based report.

UNLABELLED: The aim of this population-based study was to analyze and describe the epidemiological characteristics and trends of malignant pleural mesothelioma in the province of Sassari (Sardinia, Italy), in the period 1992-2010. Data were obtained from the local tumor registry which makes part of a wider registry web, coordinated today by the Italian Association for Tumor Registries. The overall number of malignant pleural mesothelioma cases registered was 70. The male-to-female ratio was 4:1 and the mean age 65.1 years for males and 63.4 years for females. The standardized incidence rates were 1.2/100,000 and 0.3/100,000 and the standardized mortality rates 0.6/100,000 and 0.2/100,000 for males and females respectively. A trend to increase in incidence in recent years was evidenced. This trend seems to follow the general national tendency and it depends on a large diffusion of asbestos usage in the past, delayed legislative interventions and probably a cleaning strategy of residual contamination fonts to intensify. The relative 5 years survival was low, suggesting the necessity to further intensify research and cure methods for the treatment of this extremely aggressive disease. KEY WORDS: Asbestos exposure, Mesothelioma, Pleura, Sassari.
