Fresh autologous stromal tissue fraction for the treatment of knee osteoarthritis related pain and disability.

Knee osteoarthritis (KOA) is a very common condition with multifactorial etiology leading to severe pain and disability in the adult population. Although KOA is considered a non-inflammatory arthritis, upregulation of inflammatory and catabolic pathways with increased production of proinflammatory cytokines leading to cartilage degradation and extracellular matrix degeneration has been reported. Intra-articular injection of fresh fat derived stromal vascular fraction (SVF) fraction has been proposed as a valid and alternative treatment for symptomatic KOA that guarantees mechanical support through viscosupplementation, anti-inflammatory, and anabolic action. We retrospectively reviewed a case series of 84 consecutive adult patients with KOA who underwent intra-articular injection of fresh fat derived SVF. Significant improvement in pain levels (NRS score decrease 3.5±1.1, p<0.001), WOMAC pain (-7.02±3.45 score change, p<0.001), WOMAC stiffness (-1.97±1.02, p<0.001), and ROM improvement (+17.13±5.22°, p<0.001). The only complication noted was knee joint swelling lasting for less than 7 days after the injection in 7% of the patients.

Is Myotomy Plus Diverticulopexy Suitable for Symptomatic Zenker's Diverticula?

The aim of the study was to prospectively evaluate the outcome of myotomy plus diverticulopexy over short and long-terms. A prospectively collected consecutive series (2007-2017) of 37 patients undergoing myotomy plus diverticulopexy was analyzed for clinical condition, operative information, peri-operative events, and follow-up by means of interview and physical examination. Diverticulopexy was scheduled regardless of the diverticulum's features and patient condition, other than operability. There was no choice or selection between possible treatment options. Patients were evaluated pre-operatively, at post-operative day 30 and after 1 year. Follow-up aimed at assessing the subjective condition following treatment. During the interview, patients were asked to self-assess their ability to swallow before and after surgery. No patient had peri-operative events, complications associated with the procedure, wound infection or impaired swallowing. All patients could start drinking the day after operation, could return to solid diet on post-operative day 2 and be discharged on post-operative days 3-4. Barium swallowing was not necessary before discharge. Full solid diet was resumed according to patient's compliance from post-operative day 2 (some patients refused solid diet soon after the operation even if asymptomatic). Follow-up ranged between 1 and 8 years. No patient was lost at follow-up. No disease recurrence was observed. Finally, no patient needed or sought for a clinical examination between the follow-up calls. Patients reported at least 50% improvement of symptomatology after 1 year. Diverticulopexy appears to be clinically safe, methodologically reproducible, and an effective procedure; it avoids suturing and offers good outcome results along with high patient satisfaction.

Surgery and perioperative management for post-intubation tracheoesophageal fistula: case series analysis.

BACKGROUND: Post-intubation tracheoesophageal fistula (PITEF) is an often mistreated, severe condition. This case series reviewed for both the choice and timing of surgical technique and outcome PITEF patients. METHODS: This case series reviewed ten consecutive patients who had undergone esophageal defect repair and airway resection/reconstruction between 2000 and 2014. All cases were examined for patients: general condition, medical history, preparation to surgery, diagnostic work-up, timing of surgery and procedure, fistula size and site, ventilation type, nutrition, post-operative course and complications. RESULTS: All patients were treated according to Grillo's technique. Overall, 6/10 patients had undergone a preliminary period of medical preparation. Additionally, 3 patients had already had a tracheostomy, one had had a gastrostomy and 4 had both. One patient had a Dumon stent with enlargement of the fistula. Concomitant tracheal stenosis had been found in 7 patients. The mean length of the fistulas was 20.5 mm (median 17.5 mm; range, 8-45 mm), at a median distance from the glottis of 43 mm (range, 20-68 mm). Tracheal resection was performed in all ten cases. The fistula was included in the resection in 6 patients, while it was excluded in the remaining 4 due to their distance. Post-repair tracheotomy was performed in 3 patients. The procedure was performed in 2 ventilated patients. Morbidity related to fistula and anastomosis was recorded in 3 patients (30%), with one postoperative death (10%); T-Tube placement was necessary in 3 patients, with 2/3 decannulations after long-stenting. Definitive PITEF closure was obtained for all patients. At 5-year follow-up, the 9 surviving patients had no fistula-related morbidity. CONCLUSIONS: Primary esophageal closure with tracheal resection/reconstruction seemed to be effective treatment both short and long-term. Systemic conditions, mechanical ventilation, detailed preoperative assessment and appropriate preparation were associated with outcome. Indeed, the 3 patients who had received T-Tube recovered from anastomotic complications.

Thoracic duct lesions in thyroid surgery: An update on diagnosis, treatment and prevention based on a cohort study.

INTRODUCTION: Thoracic duct fistula at the cervical level is a severe but rare complication following thyroid surgery, particularly associated to lateral dissection of the neck and to mediastinal goiter. METHODS: we retrospectively analyzed chylous fistulas observed in a cohort of 13.224 patients underwent surgery for thyroid disease since 1986 to 2014, in the Unit of Endocrine Surgery, S. Maria University Hospital, Terni, Italy. RESULTS: We observed 20 cases of chylous fistula. Thirteen patients underwent primary surgery in our institution while the remaining 7 cases had been referred to our Department from other hospitals for an already diagnosed lymphatic leak. Surgical procedures carried out included total thyroidectomy for mediastinal goiter in 4 patients, total thyroidectomy for cancer in 2 patients, unilateral functional lymphadenectomy in 11 patients and bilateral in 3. Intraoperative repair was carried out in 4 cases. Of the remaining 16 cases, 4 of the 6 fistulas with low flow leakage healed in about 30 days of conservative treatment, 2 cases instead required surgical repair. All 10 patients with "high-flow" fistula underwent surgery. Despite surgery was performed later, postoperative course in patients with late surgical repair is similar to what observed in those patients with early surgical repair. Both groups underwent cervical drainage removal in post-operative day 4. CONCLUSION: Healing of a cervical chylous fistula can be achieved by conservative medical therapy (nutritional and pharmacological) but in case of therapeutic failure with rapid decrease of general condition, the surgical approach is necessary. In our experience, duct ligation after unsuccessful conservative treatment, is the only resolutive treatment.

Thyroid cancer invading the airway: diagnosis and management.

INTRODUCTION: Aim of this study is to analyze outcome and the decision making process to approach airway invasion by thyroid tumors. METHODS: Retrospective study of 30 years experience in thyroid surgery for cancer invading airway. Clinical records, surgical and pathology reports have been analyzed to assess which principles and procedural details are significant to facilitate efficient diagnosis, staging and treatment. Medical therapy was not evaluated. RESULTS: Out of a consecutive series of 2165 thyroid cancer patients, T4a cancers are 303 (14%). Airway invasion was found in 141 (6.5%) cases. Well-differentiated pattern was determined in 110 (78%) while other histology was reported in 31 (22%). Airway-related symptoms have been recorded in 111 (78%) patients. Flexible bronchoscopy was performed in all patients. Rapidly evolving disease or non-resectable airway was found in 105 (74.5%) cases. Permanent tracheotomy was performed in 43 (30.5%) cases, airway lumen restoration with or without stenting in 39 (27.7%), laryngectomy in 8 (5.7%), segmental airway resection and reconstruction in 28 (19.9%). Perioperative mortality was recorded after palliative treatment only. In resected patients, completely radical surgery was not always achievable. All patients with positive margin after resection underwent adjuvant treatment and showed comparable survival to radical surgery patients after 5 years. Tumor relapse occurred in 8 (28.6%) cases (distant or locoregional). Patients with unresectable disease require treatment for symptoms relief but survival is poor. CONCLUSION: Although some patients are currently referred with a severely advanced disease, the indication for tracheotomy, salvage procedures or supportive care has decreased over time. Resection is feasible for differentiated tumors with an overall good outcome.

The Outcome of Primary Subglandular Breast Augmentation Using Tumescent Local Anesthesia.

BACKGROUND: Tumescent local anesthesia (TLA) technique to obtain regional anesthesia and vasoconstriction of the skin and subcutaneous tissues is routinely adopted for several plastic surgery procedures. Here, we describe the use of TLA in primary subglandular breast augmentation. This series evaluates advantages and disadvantages of TLA in elective augmentation breast surgery as well as patients' response to this procedure. METHODS: Between December 2008 and November 2011, 150 patients underwent bilateral primary subglandular breast augmentation under TLA and conscious sedation in the presence of a board-certified anesthesiologist. Midazolam 0.05 mg/kg IV and ranitidine 100 mg IV were given as premedication. Tumescent local anesthesia was composed of 25 mL of lidocaine 2%, 8 mEq of sodium bicarbonate, and 1 mL of epinephrine (1 mg/1 mL) in 1000 mL of 0.9% NS. The solution was delivered between the pectoral fascia and the mammary gland via a spinal needle. After infiltration, 45 minutes were allowed before surgery for local anesthetic effects to take place. RESULTS: The mean age of the patients was 34.3 years. The average amount of tumescent solution infiltrated was 1150 mL, with a maximal dose of 17 mg/kg of lidocaine used. Operating time was 45 minutes and recovery room time averaged 125 minutes. Minor complications were found in a total of 9 (5.3%) patients, with no main surgery-related complications such as hematoma or seroma formation. CONCLUSIONS: Breast augmentation under TLA and conscious sedation proved to be safe in the presence of a board-certified anesthesiologist and when performed with meticulous surgical technique.

The effect of norepinephrine versus epinephrine in irrigation fluid on the incidence of hypotensive/bradycardic events during arthroscopic rotator cuff repair with interscalene block in the sitting position.

PURPOSE: To compare the occurrence rate of hypotensive and bradycardic events (HBEs) during arthroscopic rotator cuff repair performed with interscalene brachial plexus block anesthesia in the sitting position in 2 groups of patients who underwent the procedure with norepinephrine or epinephrine added to the irrigation fluid. The secondary objective was to evaluate the efficacy of norepinephrine in comparison with epinephrine in controlling intraoperative bleeding and maintaining adequate visualization of the arthroscopic field of view during the procedure. We hypothesized that norepinephrine added to the irrigation fluid during shoulder arthroscopy in the sitting position would reduce the occurrence of HBEs, allowing optimal intraoperative bleeding control. METHODS: One hundred twenty patients underwent an arthroscopic rotator cuff repair performed under peripheral anesthesia and in the beach-chair position. Patients were randomly divided into 2 groups of 60 cases each: Norepinephrine (0.66 mg/L) and epinephrine (0.33 mg/L) were added to irrigation bags in group N and group E, respectively. The primary outcome was the occurrence rate of HBEs during surgery. The secondary outcomes were timing of onset of HBEs, accompanying symptoms, and intraoperative bleeding that impaired arthroscopic visualization. The clarity of the visual field was rated postoperatively by the surgeon using a visual analog scale. Comparison between groups for all baseline variables and outcome measurements was performed with the χ(2) or Fisher exact test, as appropriate, for categorical variables and the Student t test or Mann-Whitney U test, as appropriate, for continuous variables. Significance was set at P < .05. RESULTS: One patient was excluded from group E because of block failure; therefore 119 patients were finally included in the study. Comparison between groups showed no significant differences in baseline characteristics. The occurrence rate of HBEs was significantly greater in group E (n = 15) than in group N (n = 5) (P = .02). No differences between groups were found in the average time of onset of HBEs, accompanying symptoms, and clarity of the visual field. CONCLUSIONS: Continuous administration of norepinephrine, 0.66 mg/L, diluted in irrigation fluid during arthroscopic rotator cuff repair with the patient in the beach-chair position reduces the incidence of HBEs and is as effective as epinephrine in controlling intraoperative bleeding and maintaining the visual clarity of the surgical field. LEVEL OF EVIDENCE: Level I, randomized clinical study.

Metaplastic carcinoma of the breast: Treatment, results and prognostic factors based on international literature.

Metaplastic carcinoma of the breast (MCB) is a rare form of cancer containing mixture of epithelial and mesenchymal elements in variable combinations. Few and conflicting clinical data are available in the literature addressing optimal treatment modalities, prognosis and outcome. A retrospective study was conducted to review all patients with MCB diagnosed and treated at Breast Unit of Azienda Ospedaliera "Santa Maria" Terni - Italy between 2001/2010. The aim is to describe patient's clinic pathologic features and to analyze treatment results. Six female patients were studied. The median age was 48 years (range 14/58). The median tumor size was 9 cm. (range 3/18 cm.). Two cases (33%) were identified as purely epithelial and 4 (67%) as mixed epithelial and mesenchymal metaplasia. Hormone receptors were positive in only 2 patients. Modified radical mastectomy performed in 3 patients and 5 underwent axillary node dissection. Adjuvant chemotherapy was given to all patients and postoperative radiotherapy to 4. Four patients relapsed with median time of relapse of 12 months. MCB is an aggressive form of breast cancer associated with poor outcome, high incidence of local recurrence and pulmonary metastases. The disease tends to be estrogen/progesterone receptor negative. Tumor size has an important impact on outcome. The best treatment approach is yet to be defined.

Surgical margins in breast-conserving therapy: current trends and future prospects.

Inadequate surgical margins represent a high risk for adverse clinical outcome in breast-conserving therapy (BCT) for early-stage breast cancer. The majority of studies report positive resection margins in 20% to 40% of the patients who underwent BCT. This may result in an increased local recurrence (LR) rate or additional surgery and, consequently, adverse effects on cosmesis, psychological distress, and health costs. In the literature, various risk factors are reported to be associated with positive margin status after lumpectomy, which may allow the surgeon to distinguish those patients with a higher "a priori" risk for re-excision. However, most risk factors are related to tumor biology and patient characteristics, which cannot be modified as such. Therefore, efforts to reduce the number of positive margins should focus on optimizing the surgical procedure itself, because the surgeon lacks real time intraoperative information on the presence of positive resection margins during breast-conserving surgery. This review presents the status of pre- and intraoperative modalities currently used in BCT. Furthermore, innovative intraoperative approaches, such as positron emission tomography, radio-guided occult lesion localization, and near-infrared fluorescence optical imaging, are addressed, which have to prove their potential value in improving surgical outcome and reducing the need for re-excision in BCT.

Breast metastasis from a pulmonary adenocarcinoma: Case report and review of the literature.

Breast metastasis from extra-mammary malignancy is rare. An incidence of 0.4-1.3% has been reported in the literature. The primary malignancies most commonly metastasizing to the breast are leukemia, lymphoma and malignant melanoma. We present a case of metastasis to the breast from a pulmonary adenocarcinoma, diagnosed concomitantly with the primary tumor. A 43-year-old female presented with dyspnea and a dry cough of 3 weeks' duration. A subsequent chest radiograph revealed a massive pleural effusion. Additionally, on physical examination, a poorly defined mass was noted in the upper outer quadrant of the right breast. The patient underwent bronchoscopy, simple right mastectomy and medical thoracoscopy. Following cytology, histology and immunohistochemistry, primary lung adenocarcinoma with metastasis to the breast and parietal pleura was diagnosed. Histologically, both the primary and metastatic anatomic sites demonstrated a micropapillary component, which has recently been recognized as an important prognostic factor. Although the patient received chemotherapy, she succumbed to her condition within 8 months. Accurate differentiation of metastasis from primary carcinoma is very important as the treatment and prognosis of the two differ significantly.

A rare breast tumor: solid neuroendocrine carcinoma.

BACKGROUND: Solid neuroendocrine carcinoma of breast (NECB) is extremely rare. In this paper, we present a case of inflammatory primary solid neuroendocrine carcinoma of breast managed by surgery and chemotherapy and a brief review of the epidemiology, clinical features, diagnosis, pathologic features, treatment, and prognosis of solid NECB. METHODS: A 63-year-old woman was admitted in our institution with inflammatory primary solid neuroendocrine carcinoma of breast. A bulky mass of 6,5 cm tumor was located in the upper-outer and intern quadrant of her right breast. The patient underwent neo-adjuvant chemotherapy, and subsequent radical mastectomy with axillary lymph node dissection. Microscopically, the tumor was classified as solid cohesive, the tumor cells were positive for neuroendocrine markers chromogranin A and synaptophysin. 19 lymph nodes of 27 were metastatic. RESULTS: Local recurrence and metastatic progression was noted only one month after the surgery, the patient was managed by chemotherapy and hormone-therapy. She is still alive, 24 months after diagnosis. CONCLUSIONS: Solid neuroendocrine carcinoma is a subtype of mammary carcinoma with several distinctive features. Because of the rarity of this disease, there is no standard treatment, they are characterized by a higher propensity for local and distant recurrence, This case reinforces the importance to explore the novels therapeutics regimen and one of ways to explore is the use of VP16-cisplatine as treatment as it was partially efficacy for this kind of tumor.

External longitudinal titanium support for the repair of complex pectus excavatum in adults.

Several techniques exist for the repair of complex pectus excavatum. The placement of retrosternal metal bars improves the results by reducing the recurrence rate, but entails several possible risks, complications and disadvantages. A new method, specifically conceived for the repair of severe, asymmetric forms in adult patients, is reported. The corrected bone is fixed in the proper position by two, patient-customized, titanium struts, externally screwed to the manubrium and sternal body. Any retrosternal bar is thus avoided, reducing possible complications, without hampering the chest wall dynamic. In this particularly difficult issue, this technique provides long-term good functional, mechanical and cosmetic results and does not entail a second surgery for struts removal.

Therapeutic options in locally advanced thyroid carcinoma. Our experience.

INTRODUCTIONS: Thyroid cancer is the most common endocrine malignancy with an incidence equal to 1% of all malignant tumors. Prognostic factors affecting survival are manifold, including in several classifications (AMES, AGES, CORN and TNM). In this sense, the invasion of adjacent structures is one of the most important variables. The authors describe the experience of a single center in surgical treatment of advanced thyroid cancer. MATERIALS AND METHODS: Between 1986 and 2010 , 1565 patients were undergoing surgery with thyroid cancer. In particular, 1403 interventions were made for differentiated cancer, 97 for medullary carcinoma, 25 for insular carcinoma, 29 for anaplastic carcinoma, 2 for plasmacytoma, and 7 for lymphoma and 2 for angiosarcoma. Among these 896 showed invasion of adjacent structures and / or distant metastases. RESULTS: There were no perioperative deaths or major complications. Surgical procedures consisted of: 13 loboistmectomy, 519 total thyroidectomy (TT), 325 TT with lymphadenectomy of the central compartment, 7 TT with radical lymphectomy, 621 TT with functional lymphectomy, 6 TT with breast lumpectomy, 5 TT with with video-assisted lung metastasectomy, 16-TT with resection and tracheal anastomosis, 6 TT with laryngotracheal resection, 3 TT with laryngectomy, 4 TT with trachetomy, 28 TT with respiratory stent placement, 12 tracheotomy. At present, 1328 patients were free of disease, while 104 showed recurrence. Total of 133 deaths were recorded, all linked to disease relapse. DISCUSSION: The role of surgery in the treatment of advanced thyroid cancer is still undeniable. In the presence of extracapsular trespassing, in fact, the adoption of interventions demolition permits long-term survival, given the lack of aggressiveness of the tumor differentiated representing the majority of cases. The aim of surgical radicalization addition, even in the presence of distant metastases, it is justified by the possibilities offered by the therapeutic radioiodine treatment, which is not feasible in the presence of significant amounts of thyroid tissue which picks. In the presence of undifferentiated tumors, finally, endoscopic or surgical treatment may be indicated by simple purpose of palliation of respiratory symptoms.

Shock induced by spontaneous rupture of a giant thymoma.

Spontaneous bleeding of thymoma is a very rare event. We report the case of a 73-year-old woman who was referred to our hospital for acute onset of chest pain followed by shock. Chest computed tomographic scanning showed a huge mediastinal tumor with abundant left pleural effusion and contralateral shift of the mediastinum. Emergency surgical treatment was carried out through a clamshell incision. At the opening of the left pleura 1,600 mL of fresh blood was found, originating from a rupture of the tumor's capsular veins. The lesion was completely resected, en-bloc with a wide pericardial excision. The postoperative course was uneventful. The pathology report classified the lesion as thymoma AB.
