Free composite groin flap to solve a complex loss of tissue in a traumatic injury of the foot: A case report.

Severe traumatic losses of soft tissues and bone at foot and ankle level are often treated by means of amputation, but this may involve important psychological and anatomic consequences for the patient. If there are good vascular conditions, reconstruction by means of composite free flaps is often the only alternative to this demolitive treatment. The transfer of composite free flaps that include vascularized bone from various donor sites may provide anatomical reconstruction and recovery of function of the foot and ankle. If plantar skin and its sensation are present, these techniques may represent a good choice in the treatment of complex injuries of the foot, and by means of skeletal morphological reconstruction, they may give good functional results. With these premises, we report a case in which was used a groin flap to fill and solve a complex defect of bone and soft tissues of midfoot in a gunshot injury.

Unlocked versus dynamic and static distal locked femoral nails in stable and unstable intertrochanteric fractures. A prospective study.

INTRODUCTION: Few clinical studies have analyzed the utility of distal interlocking screws in stable and unstable intertrochanteric fractures treated with intramedullary devices. We performed a prospective analysis comparing short unlocked versus short dynamic and short static distal locked intramedullary nails. MATERIALS AND METHODS: Nine level-II trauma centres were involved in the study. 240 patients over the age of 65 with a stable (AO/OTA 31-A1) or unstable intertrochanteric fracture (AO/OTA 31-A2) were prospectively investigated. The same type of nail was used in every patient. Patients were randomly divided into 3 groups according to the type of distal locking used. Intra-operative variables were examined and patients were followed clinically and radiographically at 1, 3, 6, 12 months postoperatively. All complications were recorded. RESULTS: A total of 212 patients completed 1 year of follow-up visits. In the Unlocking Group (UG) the operation time, blood loss, fluoroscopy time, total length of incision were significantly decreased compared to both the Dynamic Group (DG) and the Static Group (SG) (p < 0.05). Conversely, no reliable differences in intraoperative variables were noted between the Dynamic Group and the Static Group (p > 0.05). In terms of time of fracture union we found no differences among the three Groups (p > 0.05). Moreover, no cases of limb shortening >1 cm or varus collapse were detected in any group. The 3 Groups were similar in terms of HHS, SF-12 and Barthel index results at 1-year follow-up (p > 0.05). Finally, no significant differences were demonstrated across the three Groups in terms of major complications. CONCLUSIONS: This clinical study further confirms the hypothesis that short intramedullary nails do not need to be locked for stable and unstable intertrochanteric fractures.

The potential role of quantitative digital subtraction angiography in evaluating type B chronic aortic dissection during TEVAR: preliminary results.

OBJECTIVE: To evaluate the role of quantitative digital subtraction angiography (Q-DSA) with parametric color coding (PCC) in assessing patients with type B chronic thoracic aortic dissection (TBCAD) during thoracic endovascular aortic repair (TEVAR) procedures. PATIENTS AND METHODS: A total of 11 patients electively treated in our Department for a TBCAD were retrospectively enrolled. All cases were treated with TEVAR for false lumen aneurysm of the thoracic descending aorta. For digital subtraction angiography (DSA) series post-processing, a newly implemented PCC algorithm was used to turn consecutive two-dimensional images into a single color-coded picture (syngo iFLOW, Siemens AG, Forchheim, Germany). In consensus reading, two clinicians experienced in vascular imaging evaluated the DSA series in blinded assessment and compared them to the color-coded images. PCC was assessed for its accuracy in identifying the true and false lumen as well as whether it could provide improved visualization in pre-deployment stent grafting and the final evaluation of treatment. RESULTS: PCC facilitated the visualization of the aortic dissection angioarchitecture in terms of contemporary true and false lumen vision in 81.8% of the cases. In 72.7% of the procedures, Q-DSA was estimated to improve aorta information assessment in terms of false lumen viewing, and it was possible to identify the proximal entry tear position in 45.4% of the cases. After stent graft deployment, in 72.7% of the cases (all 8 patients in which the aortic arch false lumen was visible in pre-treatment), Q-DSA confirmed the absence of early false lumen reperfusion. CONCLUSIONS: Our results indicate that Q-DSA could be useful in the intraprocedural evaluation of patients with aortic dissection during TEVAR procedures without additional x-ray costs and contrast exposure.

Is distal locking with short intramedullary nails necessary in stable pertrochanteric fractures? A prospective, multicentre, randomised study.

We investigated whether a proximal femoral nail can be implanted without a distal locking screw in AO/OTA 31-A1 and 31-A2 pertrochanteric stable femur fractures. A multicentre, randomised study was conducted in six level-two trauma centres in our area (Puglia, Italy). A total of 333 patients received their allocated intervention (162 in the locking group [LG] and 171 in the unlocking group [UG]) and 266 patients were included in the final analysis at 1year. Our data showed no statistically significant difference between the two groups at 1-year follow-up for ability to walk, SF-36 questionnaire results, residual pain (visual analogue scale [VAS] score) and level of overall satisfaction. There were also no statistically significant differences between groups for mortality and length of hospital stay. Conversely, the UG was associated with shorter operation and fluoroscopy times, shorter surgical incision length, and less blood loss and residual thigh pain. Pertrochanteric stable fractures (31-A1, 31-A2) can be treated successfully with intramedullary nails without distal locking, reducing patient and clinical personnel radiation exposure and sanitary costs (surgery time and screws costs).

Electroporation Enhances Bleomycin Efficacy in Cats with Periocular Carcinoma and Advanced Squamous Cell Carcinoma of the Head.

BACKGROUND: Advanced carcinoma of the head represents a substantial health problem in cats for local control and overall survival. OBJECTIVES: Evaluate the capability of electrochemotherapy (ECT) to improve bleomycin efficacy in cats with periocular carcinoma and advanced carcinoma of the head. ANIMALS: Twenty-one cats with periocular carcinoma (17 squamous cell carcinoma [SCC] and 4 anaplastic carcinoma) and 26 cats with advanced SCC of the head. METHODS: Nonrandomized prospective controlled study. Periocular carcinoma cohorts: 12 cats were treated with bleomycin (15 mg/m(2) i.v.) coupled with ECT under anesthesia; 9 cats were treated with bleomycin alone. Advanced head SCC cohorts: 14 cats were treated with bleomycin (15 mg/m(2) i.v.) coupled with ECT administered under sedation; 12 control cats were treated with bleomycin alone. ECT treatments (2-8) were performed every other week until complete remission (CR) or tumor progression occurred. RESULTS: Toxicities were minimal and mostly treated symptomatically. Overall response rate in the ECT treated animals was 89% (21 Complete Response [CR] and 2 Partial Response [PR]) whereas controls had response rate of 33% (4 CR and 3 PR). Median time to progression in ECT group was 30.5 months, whereas in controls it was 3.9 months (P < .0001). Median time to progression for ECT cohorts was 24.2 months for periocular cohort and 20.6 in advanced head SCC cohort, respectively. CONCLUSIONS: Electrochemotherapy is well tolerated for advanced SCC of the head in cats; its use may be considered among loco-regional strategies for cancer therapy in sensitive body regions such as periocular region.

Tuberculosis-related stigma leading to an incomplete contact investigation in a low-incidence country.

A contact investigation following a case of infectious tuberculosis (TB) reported in a call centre in Milan (Italy) led to the identification of three additional cases that had occurred in employees of the same workplace during the previous 5 years, one of whom was the probable source case. Thirty-three latent infections were also identified. At the time of diagnosis, the source case, because of fear of stigma related to TB, claimed to be unemployed and a contact investigation was not performed in the workplace. Cases were linked through genotyping of Mycobacterium tuberculosis. TB stigma has been described frequently, mainly in high-incidence settings, and is known to influence health-seeking behaviours and treatment adherence. The findings in this report highlight that TB-associated stigma may also lead to incomplete contact investigations. Little is known about the causes and impact of TB-related stigma in low-incidence countries and this warrants further exploration. Research is also needed to evaluate the effectiveness of specific interviewing techniques and training interventions for staff in reducing feelings of stigma in TB patients. Finally, the outbreak emphasizes the importance of integrating routine contact investigations with genotyping.

Recurrent varicose veins of the legs: a single centre experience.

AIM: The aim of our study is to report our experience on the surgery for recurrent varicose veins of the legs over the period 2007-2012. MATERIALS AND METHODS: A series of 480 consecutive surgical procedures for varicose veins of the legs was reviewed; among a total of 480 cases, 65 procedures were for recurrent varicose veins. Data collected included clinical characteristics, surgical techniques, cause of recurrence and surgical outcomes. We analyzed the causes of recurrences in order to determine factors that influence recurrence itself. RESULTS: Sixty-five procedures for recurrent varicose veins were analized. The main causes of recurrence were: persistence of collaterals at the saphenofemoral junction (27.7%), inadequate stripping of the long saphenous vein (18.5%), perforating veins insufficiency (66.1%), sapheno-femoral junction neovascolarisation (12.3%), inguinal or popliteal cavernoma (27.7%), recurrence after short saphenous venous surgery (4.5%). CONCLUSIONS: We concluded that, as is clear from our study, the main cause of recurrence is inadequate surgery. This can only be due to inadequate preoperative assessment (lack of rigorous clinical and US Doppler rigorous evaluation) and not correct surgical technique, as it may occur if the surgery is performed by a surgeon inexperienced in this type of surgery.

Electrochemotherapy treatment for bilateral pleomorphic rhabdomyosarcoma in a cat.

A 13-year-old male neutered cat was presented for the sudden growth of two nodular lesions close to the upper eyelid of both eyes. Fine-needle aspiration cytology was suggestive of mesenchymal neoplasia. The cat had conservative surgical excision in order to preserve the eyelids' functionality; however, the histopathological report came with a diagnosis of incompletely excised bilateral pleomorphic rhabdomyosarcoma. Due to the local aggressiveness of this neoplasm, the cat was treated with two sessions of cisplatin-based electrochemotherapy, delivered 14 days apart. Systemic or local toxicities were not detected during the whole course of therapy. The cat is still in complete remission after 12 months. Electrochemotherapy is a safe and efficacious adjuvant therapy for aggressive sarcomas and warrants further investigations in order to standardise its protocols.

Autoimmune hemolytic anemia in multicentric Castleman's disease.

We report on a patient affected by multicentric Castleman's disease who developed an acute immunohemolytic anemia due to warm antibody. The clinical course was characterized by refractoriness to the steroidal treatment and by a dramatic improvement of the hematological and objective picture following combination chemotherapy (CHOP regimen). The possible existence of a link between the lymphoproliferative syndrome and the immunological derangement is also discussed.

Specificity of autoantibodies against oxidized LDL as an additional marker for atherosclerotic risk.

BACKGROUND: LDL oxidation is a crucial step in the development and progression of atherosclerotic lesions. The detection of an increase in the anti-oxidized LDL antibody titre may thus represent a biological marker of enhanced LDL oxidation in vivo. METHODS: The occurrence of anti-oxidized LDL autoantibodies was investigated in control patients, in patients with atherosclerotic coronary artery disease, in those without clinically relevant signs of atherosclerosis, but considered at risk, and in patients with chronic alcohol-related liver disease. RESULTS: Anti-oxidized LDL autoantibodies were present in the plasma of the majority of patients with overt coronary atherosclerosis. An increased antibody titre can also be detected well before the onset of clinically relevant signs of the atherosclerotic disease in patients classically considered at risk, indicating the occurrence of in-vivo LDL oxidation during atherosclerosis development. The specificity of molecular targets (LDL) for oxidative modifications is supported by the demonstration that anti-oxidized LDL autoantibodies are absent in the plasma of alcoholic patients who exhibit a marked increase in biological markers of oxidative stress but do not classically develop atherosclerosis. CONCLUSION: These data demonstrate that the occurrence of anti-oxidized LDL autoantibodies could be specifically related to the promotion and progression of atherosclerosis and is not a simple epiphenomenon of any oxidative process occurring in vivo.
