Introduction and hypothesis: This study aims to compare native tissue abdominal and vaginal paravaginal repair, and to investigate whether surgical outcome was independent of operative route. Methods: Retrospective comparison of 111 displacement cysto-urethrocoeles, repaired between 1997 and 2007. Treatment was by surgeon assignment, 52 women having abdominal (APVR) and 59 vaginal paravaginal repairs. Main outcome measures were same-site prolapse recurrence, time to failure and surgical complications. Initial reliability was evaluated by chi-square test, 10-year durability by Kaplan-Meier survival analysis and Cox proportional hazards model. Results: When examined in the Cox proportional hazards model, anatomic results of APVR were more durable than a mechanically analogous transvaginal operation done [95% CI=1.029-2.708 (p value=0.038)]. Kaplan-Meier curves plateaued within 38 months. Symptom resolution was broadly equivalent. Surgical complication rate was 3.6%. Conclusions: Site-specific re-suture of torn native tissue has genuine curative potential. Most of the long-term success was attributable to site-specific repair, rather than nonspecific scar formation. © 2010 The International Urogynecological Association.

Introduction and hypothesis: This study aims to answer the question, "Does tissue augmentation improve the mechanical repair of displacement cystourethrocoele?" Methods: A retrospective cohort study comparing 108 bridging graft vaginal paravaginal repairs (89 tissue-inductive xenografts and 19 polypropylene mesh) to 59 native tissue historical controls was conducted. Main outcome measures were same-site prolapse recurrence and time to failure. Initial reliability was evaluated by chi-squared test, 10-year durability by Kaplan-Meier survival analysis and risk factors by Cox regression. Results: Late recurrence was 17.7% lower with augmentation (logrank test χ 2=8. 4, p value=0.0038<0.05, adjusted regression analysis χ 2=2.94;p value=0.0866 <0.10), implicating collagen degeneration in repair failure. Conclusions: Rebuilding the pubocervical septum, from arcus to arcus and pubic ramus to pericervical ring, satisfies the mechanical but not the metabolic hernia principles. Bridging grafts simplify technical repair (reducing prolapse persistence from 10.2% to 4.6%), and also rejuvenate adjacent connective tissue (reducing late recurrence from 22.6% to 4.9%). © 2010 The International Urogynecological Association.

Abstract Background: Several comorbidities frequently affect COPD progression. Aim of the study was to assess the prevalence of main comorbidities by gender and disease severity in a cohort of COPD patients referring for the first time to a specialist institution. Methods: The study was a non-interventional, cross-sectional investigation carried out via automatic and anonymous selection from the institutional data base over the period 2012-2015. Inclusion criteria were: subjects of both sex aged ≥40 years; diagnosis of COPD according to GOLD guidelines 2014; the availability of a complete clinical record file. Variables collected were: lung function; smoking history; BMI; the Charlson Comorbidity Index (CCI); number and kind of comorbidities for each patient. Results: At least one comorbidity of clinical relevance was found in 78.6 % of patients, but at least two in 68.8 %, and three or more were found in 47.9 % of subjects. Mean CCI was 3.4 ± 1.6sd. The overall prevalence was 2.6 comorbidities per patient, but 2.5 in males, and 3.0 in females, respectively (p < 0.05). Cardio-vascular disorders were the most frequent, but significantly more frequent in males (44.7 vs 30.7 %, respectively), while the metabolic, the digestive and the osteo-articular disorders were prevailing in females (12.4 vs 9.2; 14.2 vs 4.8, and 6.0 vs 3.8, respectively). In particular, chronic cor pumonale and arrhythmias mainly prevailed in men and congestive heart failure in females, while arterial hypertension resulted equally distributed. As concerning respiratory disorders, pneumonia, pleural effusions and chronic respiratory failure were more frequently found in men, while bronchiectasis and asthma-COPD overlap syndrome (ACOS) in females. Anaemia, gall bladder stones, osteoporosis and spontaneous fractures mostly prevailed in females, while gastric disorders of inflammatory origin and arthrosis were more frequent in males. Cognition disorders, dementia and signs of degenerative brain disorders were more frequently found in men, while depression in females. Finally, lung cancer was at the first place in men, but at the second in females. Conclusions: All comorbidities increased their prevalence progressively up to the last stage of COPD severity, except the cardio-vascular and the metabolic ones which dropped in the IV GOLD stage, presumably due to the high mortality rate in this severe COPD stage. The gender-dependency of comorbidities was confirmed in general terms, even if lung cancer proved a dramatic increase almost independently of sex. © 2015 Dal Negro et al.

Ten laboratories in an external quality assurance scheme used the same assay to measure anti-müllerian hormone concentration (Beckman Coulter Gen II) and received twenty serum samples distributed over a 15 month period. The mean bias for all results was only -0.089%, but there was large coefficient of repeatability of 38.8% (sample bias ranged from -37.9% to +54.7%). While each laboratory showed good reproducibility, there was a wide range of average values relative to the consensus value from -24.0% to +22.7%. This between-laboratory variability suggests clinicians should use the same laboratory to avoid problems with result interpretation. © 2013 Society for Biology of Reproduction & the Institute of Animal Reproduction and Food Research of Polish Academy of Sciences in Olsztyn.

Secondary osteoplasty by means of autogenic spongy bone grafting is the most common procedure used in the reconstruction of the continuity of the maxillary alveolar process. The aim of the study was to analyze retrospectively the effect of certain factors on the course of the bone graft healing process in patients with unilateral complete clefts of the lip, alveolar process, and palate. The investigations involved 62 children aged 8 to 14 years (mean age, 11 years) with unilateral complete cleft of the lip, alveolar process, and palate operated on at the Clinic of Plastic Surgery in Polanica Zdrój from November 2007 to April 2009. All the procedures consisted in the reconstruction of the maxillary alveolar process by means of autogenic spongy bone grafting from the iliac bone. The analysis was performed on the basis of computed tomography scans presenting maxillary alveolar processes in the horizontal cross-sectional planes performed on the second or third postoperative day and after 6 months. They were used as the basis for the measurement of the volume and density (condensation) of the bone graft, the surface of its adhesion to the maxillary alveolar bone, and the volume and density of the healed bone. The following correlation coefficients were determined: between the adhesion surface of the bone to the alveolar bone and the volume of the healed bone, between the adhesion surface of the bone to the alveolar bone and the density of the healed bone, and between the density of the graft and the volume of the healed bone. Increasing the surface of the graft adhesion to the bone ridges of the alveolar cleft contributes to increased volume of the healed bone and slows down the increase in its density (on 6-month follow-up). Crushing of the bone graft increases its resorption and reduces volume of the healed bone. Copyright © 2012 by Mutaz B. Habal, MD.

Convection-enhanced delivery (CED) is a promising new method of local drug delivery therapy for a diverse type of antitumor agents. CED offers significant advantages over systemic chemotherapy by bypassing the blood-brain barrier and obtaining adequate drug concentration with limited systemic toxicity. Actually, there is no effective treatment of malignant gliomas (MGs); survival rates remain poor despite decades of clinical trials. Conventional chemotherapy has been found to be minimally effective in the control of MG progression. CED involves the implantation of catheters through which conventional and novel therapeutic formulations can be delivered directly to the tumor using continuous, low–positive-pressure bulk flow. On the basis of the preclinical and clinical studies, we demonstrated that CED could produce effective drug delivery to large brain and tumor areas. However, clinical studies to date have not found any substantial improvement in overall survival in the treatment of MG. This overview presents up-to-date clinical results in the treatment of MG by the application of CED. © 2016 Elsevier Inc.

Pure ligamentous flexion-distraction injuries of the lumbar spine are relatively rare and even less commonly associated with neurologic compromise. They are largely related to the use of lap belt restrains during motor vehicle accidents. We report a 19-year-old female backseat passenger wearing a lap belt who was involved in a head-on collision. On admission she was paraplegic, with a T12 sensory level and no motor and sensory function of S4-S5 (American Spinal Injury Association (ASIA) A). Plain X-ray and computerized axial tomography (CAT) spine showed a flexion-distraction injury at the L3-L4 level. During surgery in the interspinous space a conus medullaris was identified, which was completely severed from the spinal cord. The patient underwent a fusion procedure and made a good recovery. Twelve months after surgery she was able to walk with a knee-ankle-foot orthosis, she has no motor function below knees, no sensation below L2, and no voluntary bladder control. Although described type of injury is very rare, one should always have in mind devastating consequences of inadequate or improperly worn seatbelts.

Background: As an alternative to other minimally-invasive approaches to facial rejuvenation, enhancement and treatment of the dermis with a compressed air molecule of hyaluronic acid (HA) is a promising method in that it lacks some of the drawbacks of other procedures. The novelty of these systems, one of which is tested in this study, is based on the supposition that jet lateral dispersion of HA produces both instant dermal augmentation and specific wound-healing processes, leading to its long-term dermal thickening. Objectives: The authors report on the efficacy and safety of the AirGent system (PerfAction, Rehovot, Israel), which is a renewal system designed to initiate a wound-healing process in the dermal layer. It is a computer-guided system that delivers treatment through compressed air molecules of HA to the dermal layer of the skin. Methods: The authors treated 20 patients (a total of 105 treatment sessions) with the AirGent system between May 2008 and November 2008. Each patient received three treatments at three- to four-week intervals. Each patient's skin thickness was measured with ultrasonography pretreatment, immediately after each session, and at six months posttreatment. Results: Seven days after the last procedure, an increase in skin thickness was observed in all patients. The most significant differences were noted in the upper lip area, where the thickness had increased by an average of 1.3 mm. Six months after the last session, an increase in skin thickness was still noted in most patients, at which time the biggest difference was noted around the eyes, where the skin remained thicker by an average of 0.77 mm over baseline. According to the results of the Global Improvement Assessment questionnaire, at the six-month follow-up to evaluate their satisfaction with the long-term results, at least 59.9% of patients still noted at least a slight improvement in their appearance. Conclusions: Although a small group of patients and a relatively short period of observation limit the scope of our conclusions, the data show that the AirGent system is efficacious in producing increases in skin thickness that correlate with at least a substantial or slight improvement of appearance, as reported by the patients themselves. © 2010 The American Society for Aesthetic Plastic Surgery, Inc.

The pathogenesis of prolapse and the requirements for a successful surgical outcome vary from one person to another. The importance of traditional risk factors is questionable, but failed previous repair is definitely an adverse prognosticator. An ideal operation should re-attach apical support to the pelvic skeleton, restore integrity within anterior and posterior suspensory hammocks and re-distribute some of the expulsive load back onto the pelvic diaphragm. Reasons for failure are best analysed by location; recurrence within the operated compartment should also be distinguished from recurrence in a different compartment. There is no all-encompassing secret to re-operating on recurrent prolapse. Success depends on sound strategic planning and using tactics to negate the greater technical difficulty and reduced collagen strength in women with prior operative failure. If an augmented repair is to be carried out, choice of biomaterials must reflect surgical objectives, movement dynamics and functional anatomy at the intended implantation site.
