RESUMO
BACKGROUND: Subtalar joint dislocation (1% of all dislocations) is the permanent loss of articular relationships in the talonavicular and talocalcaneal joints, without other involvement of the foot. Dislocation can occur medially (85%), laterally (15%), posteriorly (2.5%) and anteriorly (1%). Reduction can be performed by closed or open technique; lateral dislocations often require open reduction because of inclusion of soft tissues or bone fragments. Lateral dislocations are frequently complicated by bone exposure, risk of infection and associated soft tissues injuries. AIM OF THE STUDY: The aim of this study is to explain main characteristics and to clarify the most important pitfalls of subtalar dislocations. MATERIALS AND METHODS: We examined 47 articles published in the last thirty years (389 cases). For each dislocation we reviewed its main characteristics: direction, bone exposure, need for open reduction and for surgical stabilisation, associated injuries and method used for diagnosis. RESULTS: Medial dislocations (68.1%) has greater incidence compared to lateral ones (27.7%). Bone exposure (44.5%), associated lesions (44.5%) and need for surgical reduction (48.2%) are much more represented in lateral dislocation than in the others. CONCLUSIONS: Subtalar dislocations, especially the lateral one, represent a challenge for surgeons. Lateral subtalar dislocation occurs following high-energy trauma often involving associated injuries. Closed reduction could be unsuccessful and patients must undergo surgical reduction. After reduction CT scan is recommended. Our narrative review confirms these findings.

OBJECTIVE: Biochemical markers are commonly used in medicine to guide diagnostic investigation or therapy duration and/or monitor treatment efficacy. Due to the emergence and spread of antimicrobial resistance, markers able to prompt a more rational use of antimicrobial therapy are regarded with the greatest attention. Procalcitonin (PCT) certainly stands out among others, yet its role must be better established especially outside of the critical care area. Data about PCT utilization in non-critical patients, optimal negativity cut-offs as well as a protocol for measurement timing are all lacking. MATERIALS AND METHODS: To address these issues, a focus group was set up to propose and endorse shared statements regarding the most beneficial use of PCT in real life as infection marker for non-critical patients, based on the authors' experience and a review of recent literature. RESULTS: A group of nine experts in the fields of Infectious Diseases, Internal Medicine, Microbiology, Clinical Chemistry, Surgery and Medical Economics participated in the discussion of nine pre-specified statements. CONCLUSIONS: The potential role for PCT in differentiating infectious and non-infectious clinical syndromes and guiding antimicrobial therapy discontinuation was acknowledged. Moreover, a shared measurement protocol and desirable cut-offs for the non-critical area were proposed. Finally, observations were made about a reasonable selection of the patient population to be tested.

OBJECTIVES: To evaluate the influence of cerebral venous drainage on the pathogenesis of idiopathic sudden sensorineural hearing loss (ISSHL) and Ménière syndrome (MD). DESIGN: Observational, prospective, cohort study. SETTING: ENT and Cardiology Departments (University of Bari, Policlinico Hospital, Bari, Italy). PARTICIPANTS: We enrolled 59 consecutive patients (32 males, mean age 53.05 + 15.37 years): 40 ISSHL and 19 MD. MAIN OUTCOME MEASURE: All patients underwent physical examination, biochemical evaluation (glycemic and lipid profile, viral serology, C reactive protein, etc), audiometric (tonal, vocal, vestibular evoked myogenic potentials and auditory brainstem response test) and impedentiometric examination. The pure tone average (PTA) was calculated for the following frequencies: 250, 500, 1000, 2000, 3000, 4000, 8000. An echo-color Doppler evaluation of the venous cerebral veins, internal jugular (IJV) and vertebral veins (VV) at supine and 90° position was performed. RESULTS: No morphological alterations were found both in patients and controls. There were no signs of stenosis, blocked flow, membranes, etc. We found lower minimum, mean and maximum velocities in distal IJVs (P = .019; P = .013; P = .022; respectively) and left VVs (P = .027; P = .008; P = .001; respectively) in supine (0°) position in both MD and ISSHL patients as compared to controls. The same was for orthostatic position (90°). We found negative correlations between the velocities in extracranial veins and PTA values: therefore, the worst the audiometric performance of the subjects, the lower the velocities in the venous cerebral drainage. CONCLUSIONS: Idiopathic sudden sensorineural hearing loss and Ménière syndrome patients showed altered venous flow in IJVs and VVs as compared to controls, independently from posture. This different behavior of venous tone control can influence the ear performance and may have a role in the pathogenesis of both diseases.

RESUMO
BACKGROUND: The aim of this research was to study the epidemiology, microbiology, prophylaxis, and antibiotic therapy of surgical site infections (SSIs), especially those caused by methicillin-resistant Staphylococcus aureus (MRSA), and identify the risk factors for these infections. In Italy SSIs occur in about 5 % of all surgical procedures. They are predominantly caused by staphylococci, and 30 % of them are diagnosed after discharge. In every surgical specialty there are specific procedures more associated with SSIs. METHODS: The authors conducted a systematic review of the literature on SSIs, especially MRSA infections, and used the Delphi method to identify risk factors for these resistant infections. RESULTS: Risk factors associated with MRSA SSIs identified by the Delphi method were: patients from long-term care facilities, recent hospitalization (within the preceding 30 days), Charlson score > 5 points, chronic obstructive pulmonary disease and thoracic surgery, antibiotic therapy with beta-lactams (especially cephalosporins and carbapenem) and/or quinolones in the preceding 30 days, age 75 years or older, current duration of hospitalization >16 days, and surgery with prothesis implantation. Protective factors were adequate antibiotic prophylaxis, laparoscopic surgery and the presence of an active, in-hospital surveillance program for the control of infections. MRSA therapy, especially with agents that enable the patient's rapid discharge from hospital is described. CONCLUSION: The prevention, identification and treatment of SSIs, especially those caused by MRSA, should be implemented in surgical units in order to improve clinical and economic outcomes.
RESUMO
Multilocular cystic renal cell carcinoma is now recognized as an independent pattern by WHO; it is a rare malignancy with a predominantly cystic growth, characterized by very low oncologic evolution and then susceptible to conservative treatment. In the kidney cystic masses of different origin may arise, i.e. due to malformation, acquired disease or tumor. Renal neoplastic lesions may have a cystic or pseudocystic component. There are also four types of neoplasm with a predominantly cystic growth, including the multilocular cystic carcinoma, which are macroscopically very similar and impossible to differentiate through diagnostic pre-operative images. The Authors present four cases of multilocular cystic renal cell carcinoma diagnosed in the 2000-2007 period, with special reference to diagnostic difficulties and to pre- and intra-operative features of the neoplasm. In conclusion, the extemporaneous histological preoperative diagnosis of multilocular cystic renal cell carcinoma is not possible because it requires extensive sampling; furthermore, the final histological diagnosis sometimes needs particular immunohistochemical procedures to be confirmed.
RESUMO
BACKGROUND: Twenty-one patients who had simple rectovaginal fistulas were treated at the Surgical Department of "Tor Vergata" University from 1992 to 1996 all of whom were at the first approach. METHODS: The fistulas were treated with complete excision of the external tract and primary closure of the internal opening with advancement of a rectal mucosal flap, distal to the origin fistulas opening. The vaginal side is left open for drainage. RESULTS: Eighteen of the twenty-one patients had good results; three patients required reoperation for recurrences; all of them had satisfactory results. CONCLUSIONS: The advancement flap technique was very useful for simple rectovaginal fistulas with any sphincter damage, and it is very well tolerated by patients.

In some individuals, chronic lymphocytic leukemia (CLL) may be associated with glomerular disease from membranous nephropathy with resultant nephrotic syndrome. CLL is characterized by abnormal immunoregulation with a malignant clonal proliferation of lymphocytes. The association between the abnormal clone and nephrotic syndrome is suggested in some cases by the remission of proteinuria with a reduction in abnormal lymphocyte number after treatment with antineoplastic agents. For the first time, we describe a patient with CLL and associated membranous glomerulopathy whose nephrotic syndrome remitted after treatment with fludarabine, a new purine analogue used in the treatment of refractory CLL.

It is not an exceptional event to observe the sequelae of primary pathology of the hip in young patients that, as such, are not of the ideal age for replacement surgery. Moreover, one must not overlook the difficulties involved in replacement surgery for the treatment of inveterate modifications in the normal hip anatomy. Often, among the sequelae of primary pathology of the hip, deformities of the lower limb must also be included, associated or consequent, which also need treatment. For these reasons, the authors, in three selected cases, used a combined external fixator (circular and lateral) by means of which they were at the same time able to correct the axial deformity (with a support osteotomy), and the residual hypometria (with femoral lengthening). Osteotomy plus lengthening, using an external fixator, avoid hypometria of the limb and deformity in valgus of the knee, and allow for results which would otherwise not be obtained with replacement surgery alone.

Sixty-seven patients with chronic pilonidal sinuses were treated by excision and rhomboid flap transposition (RFT). Primary healing was obtained in all patients except two who developed a seroma and one who had a partial dehiscence of the surgical wound due to a hematoma, which necessitated drainage through the margin of the flap. The average stay was 5.3 days (range 1-16). All patients returned to normal activities within 2 weeks of surgery. No late recurrence occurred after a mean follow-up of 74.4 months (range 8-137).

Papillary histologic type is the most common form of thyroid carcinoma amounting to 85% cases. This pathology presents a rather good prognosis, but a few years ago, new subtypes have been described. Some of these variants show a fairly good prognosis i.e follicular, macropapillary, encapsulated while others appear to have a decidedly worse one, columnar cells, diffused sclerosing, or even to be clearly malignant as in the case of the tall cell variant. The authors report a case treated by a combined surgical and radiometabolic therapy and evidence the main characteristics of this rare and underestimated neoplasia.

A case of acute perforation of the small bowel in a 32-year-old man with Crohn's disease not previously diagnosed is presented. The patient underwent an emergency bowel resection and anastomosis and was put on 5-ASA for the following 4 years. No clinical or endoscopic recurrences appeared during this period. In order to avoid both functional disorders and recurrences, a surgical treatment based on resection and anastomosis in minor risk cases, i.e. in patients without abscess and/or concurrent steroid therapy, and on resections limited to grossly involved segments of bowel is advocated.

Twenty liver transplant patients were examined with MRA and color-Doppler US 18 to 40 days after surgery to investigate the onset of vascular complications after surgical liver revascularization. Vascular anastomoses are the most frequent location for such complications as stenoses, occlusions, pseudoaneurysms and vessel ruptures. In liver transplant there are 4 vascular anastomoses, i.e. hepatic artery, portal vein and superior and inferior anastomoses of the inferior vena cava. MRA images were acquired with a superconductive unit operating at 1.5 T, using fast low angle shot (FLASH) 2D sequences on the coronal plane; all images were postprocessed with the MIP algorithm. The presence of a paramagnetic artifact, the "double black spot sign", caused by the suture wire used to make the vascular anastomoses, allowed us to precisely detect the site and the flow pattern alterations at this level. MRA images were studied by two independent observers and vascular anastomosis depiction was rated as "good", "fair" and "poor". The demonstration of portal vein anastomoses was good in the whole series (20/20 patients). The superior anastomosis of the inferior vena cava was clearly depicted in 19 cases and fairly depicted in only 1 patient. The inferior anastomosis of the inferior vena cava was clearly depicted in 19 patients and fairly depicted in 1 case. Hepatic artery anastomoses were far more difficult to demonstrate than the others, considering their caliber and flow pattern, but its depiction was nevertheless good in 12 cases, fair in 6 and poor in only 2 patients. In our series, only one portal vein stenosis was observed, which was clearly depicted on both MRA and US images. In conclusion, MRA is a useful and reliable noninvasive diagnostic tool to study vascular anastomoses in liver transplant patients.

We provide evidence for a perceptual marker of neuroplasticity in female mastectomy patients who reported phantom breast perceptions. When tactile stimuli were delivered to dorso-thoracic, shoulder and pinna regions ipsilateral to the mastectomy, these patients (in some cases even 5 days after the operation) referred the stimuli to the amputated breast mainly to the nipple. The somatosensory representation of the stimulated regions is probably adjacent to the former representation of the amputated breast. These results suggest that input from stimulated regions of the skin can drive neurones originally driven by input from the amputated breast. The apparent functional relation between pinna and nipple might give clues to the mechanisms underlying referred sensations and pain.

We describe two patients with lung carcinoma in whom adrenal glands were the sole site of tumor relapse, revealed by the appearance of Addison's disease. Both patients showed bilateral adrenal masses on US and/or CAT scans and received hormone replacement therapy, with rapid improvement of their general conditions. One of them, with small-cell carcinoma, could also be treated with further chemotherapy and achieved a second remission. Therefore, we stress that patients with lung carcinoma should be periodically screened for adrenal deposits by US or CAT and undergo prophylactic steroid maintenance whenever metastatic involvement of the glands is detected.

In Leriche's "maladie post-operatoire" one of the most frequent and dangerous complications is the deep vein thrombosis (DVT). In general surgery its occurrence is between 10 and 40%, closely related to factors like patient's age, postoperative immobilization, type and time of surgery. Low molecular weight heparins (LMWH) have been recently introduced as a therapy to prevent postoperative DVT in high risk patients. LMWH seem to have all advantages of classical heparin products without their side effects. Eighty eight patients who underwent general surgery were studied in a clinical controlled trial about effectiveness of a new LMWH (Fluxum) for the prevention of postoperative DVT: 44 were treated with Calcium-heparin and 44 were treated with Fluxum. Both drugs decreased significantly the percentage of DVT, but Fluxum seemed to be better tolerated for its single-daily subcutaneous administration.
