Correction of hypospadias with a vertical preputial island flap: a 23-year experience.
No full textPurpose: We report our experience using the preputial island flap technique (Scuderi procedure) to correct penile hypospadias.
Materials and Methods: A total of 152 patients underwent repair between 1982 and 2004. Nine patients (6%) had proximal hypospadias, 46 (30%) had mid penile hypospadias and 97 (64%) had distal hypospadias. A total of 146 patients (96%) had not previously undergone surgical treatment, while 6 (4%) had undergone surgery.
Results: After the primary repair 3 patients had fistula and 10 had mild stenosis. The immediate success rate was 91.4% (139 of 152 patients), which later increased to 98% (149 of 152) after nonsurgical treatment of the stenoses.
Conclusions: Preputial island flap urethroplasty is a versatile operation that corrects hypospadias and is particularly indicated if there is associated severe penile curvature, with a low complication rate and superior cosmetic results
Power-Assisted Lipoplasty Versus Traditional Suction-Assisted Lipoplasty: Comparative Evaluation and Analysis of Output
No full textPower-Assisted lipoplasty (PAL) is a new method introduced to simplify and standardize surgical results of traditional suction-assisted lipoplasty (SAL). Comparative studies already have demonstrated PAL to be a handy, atraumatic, time- and fatigue-sparing technique. The authors performed a pilot study to compare the output capacity of PAL and SAL in 15 healthy female patients. The general and the specific per area outputs over 1 min from symmetrical areas were assessed. The results confirmed the efficiency of PAL (17.41% increase in average specific area output, as compared to SAL) and the distribution of fat in major "fat storage" areas such as the abdomen and the anterior thigh. Specific per area output indicated a higher suction capacity for PAL in all areas except the inner thigh. The efficiency of PAL seemed to be less influenced than that SAL by fat distribution
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Surgical correction of blepharoptosis using the levator aponeurosis-Müller's muscle complex readaptation technique: a 15-year experience
No full textPalpebral ptosis is defined as abnormal drooping of the upper lid, caused by partial or total reduction in levator muscle function. It may be caused by various abnormalities, both congenital and acquired. The aim of this article is to report the long-term follow-up of results obtained with the levator aponeurosis-Müller's muscle complex readaptation technique.
METHODS:
In a clinical study, 144 eyelids (102 patients) affected by congenital or acquired blepharoptosis were treated using the levator aponeurosis-Müller's muscle complex readaptation technique. Degree of ptosis and levator function were measured preoperatively and postoperatively. All patients were followed up for 1 year, 54 of them for 3 years, 22 for 5 years, and 12 for 10 years.
RESULTS:
Complete correction or mild residual ptosis was achieved in over 83 percent. All ptosis with preoperative levator function greater than 8 mm was completely corrected, whereas eyelids with poor or absent levator function showed a variable degree of postoperative correction and a statistically significant difference. Ptosis correction between eyelids with levator function greater than 8 mm or less than 8 mm was analyzed statistically using the McNemar test for paired data.
CONCLUSIONS:
This surgical technique is effective in both acquired and congenital ptosis. In particular, the authors obtained better results in those with fair to good (> 8 mm) levator function than in those with poor or absent (< or = 8 mm) levator function
