The effects of ethyl-2-cyanoacrylate and butyl-2-cyanoacrylate in the process of bone healing in rats. A controlled experimental study.

Objective: Synthetic adhesives are used by various medical specialties, especially in surgery; however, studies reporting their use in orthopedic practice are scarce. The aim of this study was to compare the results in using ethyl-2-cyanoacrylate or butyl-2-cyanoacrylate in the treatment of fractures in rats.

Methods: This was an experimental prospective controlled study in 90 rats, with humerus, femur, and tibia fractures, treated with ethyl-2-cyanoacrylate (SB group;  = 45) or butyl-2-cyanoacrylate (HA group;  = 45).

Results from surgical treatment of Morel-Lavallée lesions: prospective cohort study.

Objective: To present the results from early diagnosis and delayed surgical treatment of a cohort of patients who were diagnosed with Morel-Lavallée lesions.

Methods: Between January 2006 and December 2013, we performed delayed surgical debridement on Morel-Lavallée lesions, after delimitation of the local tissue necrosis, followed by closure through second intention and/or use of grafts/flaps.

Results: All the patients evolved with complete closure of the lesion after the delayed debridement, granulation of the operative wound and primary suturing or construction of pedunculated flaps.

Exposure of the surgical team to ionizing radiation during orthopedic surgical procedures.

Objective: the aim of this study was to assess the degree of exposure of the orthopedic surgical team to fluoroscopic ionizing radiation.

Methods: the ionizing radiation to which the orthopedic surgical team (R1, R2 and R3) was exposed was assayed using thermoluminescent dosimeters that were distributed in target anatomical regions (regions with and without protection using a lead apron). This was done during 45 hip osteosynthesis procedures to treat transtrochanteric fractures that were classified as 31-A2.

[Potential of ultrasonography and ultrasonography-guided biopsy in the diagnosis of local recurrence following radical prostatectomy].

Introduction: [corrected] We investigated the diagnostic role of combined transrectal US (TRUS) and biopsy to detect recurrent cancer after radical prostatectomy, in patients with negative bone scintigraphy and elevated prostate specific antigen (PSA) levels.

Materials And Methods: From March, 1997, to May, 1998, we examined 12 patients with persistently detectable serum PSA levels and negative bone scintigraphy. At the time of diagnosis, an average 36 months had elapsed since prostatectomy.

[Ultrasonic diagnosis of De Quervain's stenosing tenosynovitis].

This study was aimed at stressing the role of US of the first dorsal compartment of the wrist as the initial diagnostic approach in the study of De Quervain's syndrome, thanks to the high diagnostic yield of this technique. We report on 14 cases of De Quervain's stenosing tenosynovitis whose onset of the symptoms ranged 3-24 months before the US exam. The patients were subdivided into three groups, according to disease stage and US patterns; 5 patients were in group 1, six in group 2 and 3 in group 3.

[An esophagoaortic fistula due to a foreign body].

Starting from a case of aortoesophageal fistula caused by a foreign body, some aspects of the treatment of upper gastrointestinal hemorrhage of uncertain etiology are discussed. The time between bleeding and perforation often notes it possible to perform resolutive diagnostic tests (aortography, esophagoscopy, CT).

[Urography: problems and errors in the diagnosis of renal masses].

New imaging modalities have gained a prominent role in both detection and diagnosis of kidney disorders. However, excretory urography (IVU) remains the screening examination of choice in everyday diagnostic routine, even though its value in characterising renal masses is poor. The search for more sensitive and less invasive diagnostic modalities has brought about some new dilemmas--e.

[Surgical ultrasonography of the seminal vesicles in andrologic pathology. Research in progress].

The authors describe their experience with percutaneous transperineal puncture (PTP) of the seminal vesicles in andrologic pathologic conditions, using transrectal US guidance. Three cases are reported: 2 anomalies of the genital ducts and one prostatic-vesicular abscess. In the first two cases PTP allowed a diagnosis to be reached on the basis of the analysis of vesicular fluid.

[Ultrasonography in syringocele of the male urethra (ultrasound-urethrography)].

The authors have studied 5 patients with syringocele--or cystic dilatation of the excretory ducts in Cowper's glands--using a 7.5 MHz linear high-definition US probe. The urethra was distended with a saline solution introduced through a small Foley's balloon catheter placed in the navicular fossa.

[Echography vs urography in the study of small-size renal carcinoma].

Since 1981 we have studied 34 patients with renal cell carcinomas smaller than 3 cm, diagnosed by US and IVP, to evaluate the diagnostic viability of these 2 procedures. Their respective results were compared to pathologic findings and tumor grading. No correlation was found between the type of sonographic patterns and the pathologic findings.

[Ureteral obstruction secondary to aortofemoral bypass].

Hydroureteronephrosis is reported as a frequent late complication of aorto-femoral bypass grafts in patients with aorto-iliac obstruction. To define the actual incidence of this potentially critical complication, renal ultrasonography (US) was performed on 79 asymptomatic patients who had previously undergone aortic reconstruction, after a mean interval of 71.6 months.

[Diagnosis by imaging of secondary neoplastic lesions of the digestive tract].

Secondary neoplasms involving the alimentary tract are not common. This work is aimed at evaluating their characteristic roentgenological features, providing, when possible, the criteria for discriminating secondary from primary lesions. Forty-five patients with secondary neoplasms of the alimentary tract were examined by conventional radiology, ultrasonography and CT.

[Echostructural polymorphism of prostatic carcinoma. Anatomo-pathologic correlations in various developmental stages].

The sonographic appearance of prostatic carcinoma was correlated with the corresponding histopathologic studies in 57 patients after transperineal biopsy. In 21 cases the lesions observed were less than or equal to 2 cm (circumscribed) and in 36 were greater than 2 cm (diffuse). Within the first group there was a prevalence of hypoechoic forms (61,9%).

Small hepatocellular carcinoma: an Italian experience.

Recent reports have demonstrated the possibility of using ultrasound to detect hepatocellular carcinomas under 3 cm (small HCC). Our aim was to assess the incidence of small HCC in an Italian ultrasonographic series. Among 17,133 scans of unselected patients, we detected 85 HCC, 9 of which were under 3 cm.

[Diagnostic images of renal angiomyolipoma].

The authors report 26 cases of renal angiomyolipomas (AML) detected in a three-years period (1983-85). In all cases echography, in 6 renal arteriography and in 13 CT were performed. The review of the pathway and of literature stress some new aspects in diagnostic problems of AML.
