Use of penile shear wave elastosonography for the diagnosis of Peyronie's Disease: a prospective case-control study. Basic Clin Androl 2022; 32:15. [PMID: 35971058 PMCID: PMC9380314 DOI: 10.1186/s12610-022-00164-w] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2022] [Accepted: 06/13/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND To evaluate the stiffness of the tunica albuginea (TA), we used a new noninvasive diagnostic technique called shear wave elastography (SWE). We determined whether SWE values are correlated with the degree of penile curvature, the time of disease onset, and pain severity experienced by patients during erection. This study analyzed the elasticity of the TA of patients with Peyronie's disease compared to that of the control group. We also analyzed any correlations between the stiffness of the cavernous bodies and the degree of curvature, time from diagnosis to curvature onset, and erectile pain severity. This was a prospective case-control study involving 100 men enrolled from September 2020 to August 2021. Participants were divided into group A (case group, n = 50), which included men with PD, with or without pain, and with penile curvature, or group B (control group, n = 50), which included healthy patients older than 18 years who visited the urology clinic for reasons other than PD. The medical history was collected for all patients who also underwent objective examination, B-mode ultrasound evaluation, and SWE. The International Index of Erectile Function (IIEF-15) visual analog scale (VAS) questionnaire was administered to all participants. RESULTS There were no significant between-group differences regarding age, weight, and height (p > 0.05); however, there was a significant difference in the stiffness values (p < 0.05). An inverse correlation was observed between stiffness and the VAS score (p < 0.0001). A positive correlation was observed between the degree of curvature (p < 0.0001) and the time of curvature onset (p < 0.0001). The IIEF-15 scores were poorer in group A than in group B (p < 0.0001). CONCLUSION SWE is an inexpensive, noninvasive method that can be used to measure the stiffness of PD patients.

Testicular shear wave elastography in oligo-astheno-teratozoospermic individuals: a prospective case-control study. Int Urol Nephrol 2021; 53:1773-1783. [PMID: 34114152 PMCID: PMC8380242 DOI: 10.1007/s11255-021-02909-4] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2021] [Accepted: 05/31/2021] [Indexed: 12/17/2022]
Abstract
Purpose The primary objective of this study was to evaluate the testicular stiffness by ultrasound shear wave elastography (SWE) both in men with oligo-astheno-teratozospermia (OAT) and in control group. The secondary objective was to identify a possible correlation between semen quality with testicular stiffness. Methods This was a prospective case-control study. We divided the sample in two groups; Group A (case group) included men with OAT, and Group B (control group) men with normal sperm parameters. All participants had at last two semen analysis in the past 180 days (at last 90 days apart), using performed ultrasound and SWE elastography. Results We analyzed 100 participants, 50 patients in Group A and 50 controls in Group B. There were statistically significant differences in term of testicular volume and testicular stiffness between two groups. Men with OAT had the testicular stiffness value higher than the controls in both sides (left testicular stiffness 21.4 ± 5.4 kPa vs 9.9 ± 1.6 kPa, p < 0.0001; right testicular stiffness 22.9 ± 4.8 kPa vs 9.5 ± 2.4 kPa, p < 0.0001). Men with abnormal semen parameters showed an inverse correlation between the mean value of testicular stiffness and total sperm count (22.15 ± 3.38 kPa, r = − 0.387, p = 0.005), sperm concentration (22.15 ± 3.38 kPa, r = − 0.244, p = 0.04), and progressive motility (22.15 ± 3.38 kPa, r = − 0.336, p = 0.01), while the correlation was not evident in controls group. Conclusion SWE is able to differentiate between testicles with spermatogenic changes from a healthy testicle. For this reason, it could be used to evaluate, in a non-invasive way, the tissue alterations of the organ.

Shear wave elastography as a new, non-invasive diagnostic modality for the diagnosis of penile elasticity: a prospective multicenter study. Ther Adv Urol 2021; 13:17562872211007978.

Abstract
Objective: Shear wave elastosonography (SWE) could be used to evaluate the elasticity of penile tissue. Few studies in the literature, however, have investigated its use in patients with erectile dysfunction (ED) or have attempted to correlate findings with International Index of Erectile Function (IIEF-5) scores. The primary aim of this study was to evaluate the characteristics of erectile tissue using SWE and to determine possible relationships with IIEF-5 and Erection Hardness Scale (EHS) scores. The secondary aim was to establish a cut-off SWE examination value over which cavernous tissue stiffness could contribute to a subsequent organic alteration. Methods: This prospective study included male patients 18−80 years of age who attended two general andrology clinics and underwent SWE. Subjects were divided into groups according to IIEF-5 score, and correlations between SWE and IIEF-5 and EHS questionnaire scores were explored. Results: A total of 270 subjects (mean age 46.7 ± 16.9 years) were included. ED was reflected by low IIEF-5 and EHS scores and a decrease in the mean elasticity of the corpora cavernosa according to SWE, although the difference between the left and right corpora cavernosa was not statistically significant. No statistically significant correlation was found between measurements of the corpora cavernosa (in kPa) and age. The optimal cut-off identified was 24.75 kPa. Conclusion: Results demonstrated that the mean elasticity of the corpora cavernosa according to SWE was correlated with IIEF-5 score and EHS score.

Abstract
Background Peyonie’s disease (PD) mostly affects males in the fifth decade of life, with a prevalence in the general population ranging between 0.5% and 20.3%. The pathology of PD is characterized by fibrosis of the tunic albuginea of the cavernous bodies of the penis, with the presence of pain in the erection and penile deformity. This is associated with decreased sexual function for both participants. The objective of the study was to investigate the influence of PD pathology on both male patients’ and their female partners’ sexual spheres, and analyze changes in sexual function and perception following penile correction surgery. Methods Prospective study, we included male patients with PD and their female partner sexually active. Patients underwent corporoplasty with multiple plications. The male and female sexuality was evaluated before surgery and three months after male treatment by the Female sexual Function Index (FSFI); International Index of Erectile Function (IIEF); Visual Analogical Scale (VAS). Results From January 2018 to November 2019 we included 35 couple. The female subjects before partner’s surgery presented dyspareunia, loss of sexual desire, inability to achieve orgasm, and sexual dissatisfaction. At three months after surgical treatment there was an improvement of sexual function in both male patients and female partners (desire P<0.0001, arousal P<0.0001, lubrification P<0.0001, orgasm P<0.0001, satisfaction P<0.0001, pain P<0.0001). As regarding male patients the pain decreased significantly (VAS score from 6 to 2.5), while there was no statistically significant improvement in erectile function (P=0.05). Conclusions Our findings suggest that a viable approach to treatment of PD patients that involves their partners could lead to better functional and psychological results.

Abstract
The primary goal in the management strategy of a patient with ED would be to determine its etiology and cure it when possible, and not just to treat the symptoms alone. One of the new therapeutic strategies is the use of low intensity extracorporeal shockwave (LISW) therapy. The mechanism of shockwave therapy is not completely clear. It is suggested that LISW induces neovascularization and improvement of cavernosal arterial flow which can lead to an improvement of erectile function by releasing NO, VEGF and PCNA.

Abstract
OBJECTIVE A precise characterization of erectile dysfunction (ED) of vascular origin has not yet been achieved, although cavernous peak systolic velocity (PSV) is generally considered a major parameter. Nevertheless the penile dynamic color Doppler is invasive and linked to several complications. The intima-media thicknesses (IMT) of cavernosal artery would add to the predictive value of vasculogenic ED risk and outcomes. We also hypothesized the existence of a correlation between IMT cavernosal artery and IMT carotid arteries. This study seeks to evaluate these hypotheses with our experience, investigating the predictive accuracy of carotid and cavernosal Doppler ultrasound findings for discriminating patients with vasculogenic ED. MATERIAL AND METHODS A total of 59 subjects (32 vasculogenic ED patients - group A - and 27 no vasculogenic ED patients - group B) were evaluated in our andrological center from September 2012 to June 2013 and enrolled in the study. All subjects underwent medical history, erectile function domain of the International Index of Erectile Function, physical examination, routine and sex hormone blood tests, and high resolution dynamic color Doppler ultrasound evaluation of carotid and penile districts and valuation of IMT in both districts. RESULTS The values of cavernosal artery IMT in group A were higher than in group B (0,28 ± 0,06 mm vs 0,17 ± 0,07 mm). Even the values of carotid artery IMT in vasculogenic ED group were higher than in no vasculogenic ED group (0,74 ± 0,14 mm vs 0,59 ± 0,11 mm). The cavernosal IMT showed a moderate (r = 0.61) positive linear correlation (p < 0.001) with the carotid artery IMT. CONCLUSIONS An increased cavernous IMT might predict ED of vascular origin with more accuracy than PSV and could be a sensitive predictor also for systemic atherosclerosis at an earlier phase.

Abstract
Background Benign prostatic hyperplasia is a frequent disease among elderly, and is responsible for considerable disability. Benign prostatic hyperplasia can be clinically significant due to lower urinary tract symptoms that take place because the gland is enlarged and obstructs urine flow. Transurethral resection of the prostate remains the gold standard treatment for patients with moderate or severe symptoms who need active treatment or who either fail or do not want medical therapy. Moreover, perioperative and postoperative surgery complications as cardiovascular ones still occur. The incidence of acute myocardial infarction in patients undergoing transurethral resection of the prostate is controversial. The first studies showed an increase in mortality and relative risk of death from myocardial infarction in transurethral resection of the prostate group vs open prostatectomy but these results are in contrast with more recent data. Discussion Given the conflicting evidence of the studies in the literature, in this review we are going to discuss the factors that may influence the risk of myocardial infarction in elderly patients undergoing prostate surgery. We analyzed the possible common factors that lead to the development of myocardial infarction and benign prostatic hyperplasia (cardiovascular and metabolic), the stressor factors related to prostatectomy (surgical and haemodynamic) and the risk factors specific of the elderly population (comorbidity and therapies). Summary Although transurethral resection of the prostate is considered at low risk for severe complications, there are several reports indicating that cardiovascular events in elderly patients undergoing this surgical operation are more common than in the general population. Several cardio-metabolic, surgical and aging-related factors may help explain this observation but results in literature are not concord, especially due to the fact that most data derive from retrospective studies in which selection bias cannot be excluded. Subsequently, further studies are necessary to clarify the incidence of acute myocardial infarction in old people.

Abstract
BACKGROUND The open Burch colposuspension, first described in 1961 had been widely employed for the surgical treatment of women with stress urinary incontinence (SUI) caused by urethral hypermobility. We evaluated the long-term efficacy of laparoscopic Burch colposuspension (LBC) for SUI in women. METHODS A randomized prospective trial was conducted from September 2010 to January 2013. The extraperitoneal laparoscopic Burch colposuspension was performed by an operator on 96 women, mean age was 54,3 ± 3,7 years all of whom suffered from SUI or mixed urinary incontinence. Patients completed a self-administered the Short Form-36 (SF-36), the Physical Component Summary (PCS) and Mental Component Summary (MCS), the Short Urinary Distress Inventory (SUDI) and Short Incontinence Impact Questionnaire (SIIQ). at both baseline and follow up(6 weeks, 6 months, 18 months postoperatively). The Genito-Urinary Treatment Satisfaction Scale (GUTSS) was used to assess satisfaction with surgery. RESULTS After follow up was recorded an improvement of questionnaries scores. The general health score is improved after surgery (2,60 ± 1.02 versus 2,76 ± 1.06) with p = 0.09. The PCS baseline score is 46.29 ± 10.95 versus 49.54 ± 10.41 after treatment with p = 0.01, so there was a significant baseline to follow up improvement. The MCS improved also, infact baseline score is 42.19 ± 12.57 versus 42.70 ± 13.03 with p = 0.87. The SUDI baseline score is 50.22 ± 20.73 versus 23.92 ± 17.90, while SIIQ score is 49.98 ± 23.90 versus 31.40 ± 23.83 with p < 0.01. In both questionnaires there is an improvement. Satisfaction with treatment outcomes from the GUTSS at 6-month follow up is 29.5 ± 6.3 with p = 0.46. CONCLUSION The LBC has significant advantages, without any apparent compromise in short-term and long term outcomes.

Abstract
INTRODUCTION The objective of this work is to compare the effectiveness of hormonal treatment (luteinizing hormone-releasing hormone agonists and/or antiandrogens) as an early or as a deferred intervention for patients with locally advanced prostate cancer (LAPC) and/or asymptomatic metastasis. MATERIALS AND METHODS Systematic review of trials published in 1950-2007. Sources included MEDLINE and bibliographies of retrieved articles. Eligible trials included adults with a history of LAPC who are not suitable for curative local treatment of prostate cancer. We retrieved 22 articles for detailed review, of which 8 met inclusion criteria. The Veterans Administration Cooperative Urological Research Group suggested that delaying hormonal therapy did not compromise overall survival and that many of the patients died of causes other than prostate cancer. In European Organisation for Research and Treatment of Cancer (EORTC) 30846 trial, the median survival for delayed endocrine treatment was 6.1 year, and for immediate treatment 7.6 year, the HR for survival on delayed versus immediate treatment was 1.23 (95 % CI 0.88-1.71), indicating a 23 % nonsignificant trend in favour of early treatment. In EORTC 30891, the immediate androgen deprivation resulted in a modest but statistically significant increase in overall survival. The protocol SAKK 08/88 showed the lack of any major advantage of immediate compared with deferred hormonal treatment regarding quality of life or overall survival. CONCLUSIONS The early intervention with hormonal treatment for patients with LAPC provides important reductions in all-cause mortality, prostate cancer-specific mortality, overall progression, and distant progression compared with deferring their use until standard care has failed to halt the disease.

Abstract
BACKGROUND Reduced libido is widely considered the most prominent symptomatic reflection of low testosterone (T) levels in men. Testosterone deficiency (TD) afflicts approximately 30% of men aged 40-79 years. This study seeks to evaluate the effect of a new natural compound "tradamixina "in order to improve male sexual function in elderly men, particularly libido and possible erectile dysfunction, versus administration of tadalafil 5 mg daily. METHODS Seventy patients (67.3 ± 3.7 years) with stable marital relations and affected by reduced libido, with or without erectile dysfunction were recruited. They were randomly separated in 2 groups A-B of 35. Group A was administered twice a day a new compound "Tradamixina" (150 mg of Alga Ecklonia Bicyclis, 396 mg of Tribulus Terrestris and 144 mg of D-Glucosamine and N-Acetyl-D-Glucosamine) for two months, while Group B was administered tadalafil 5 mg daily, for two months. At visit and after 60 days of treatment patients were evaluated by means of detailed medical and sexual history, clinical examination, laboratory investigations (Total and Free T), instrumental examination (NPTR- nocturnal penile tumescence and rigidity test- with Rigiscan). Patients completed a self-administered IIEF questionnaire (The international index of erectile function) and SQoLM questionnaire (Sexual quality of life Questionnarie-Male). The results pre and post treatment were compared by Student t test (p<0.005). RESULTS After 2 months of treatment in group A serum TT levels (230 ± 18 ng/dl vs 671 ± 14 ng/dl ) and FT levels(56 ± 2.4 pg/ml vs 120 ± 3.9 pg/ml) increased, while in group B serum TT levels (245 ± 12 ng/dl vs 247 ± 15 ng/dl ) and FT levels(53 ± 0.3 pg/ml vs 55 ± 0.5 pg/ml) increased not statistically significant. The patient's numbers with negative NPTR improved after treatment in group A and B (15 vs 18 and 13 vs 25 respectively). The IIEF total score in group A increased after treatment with tradamixina (15 ± 1.5 vs 29.77 ± 1.2); the IIEF total score in group B increased slightly (12 ± 1.3 vs 23.40 ± 1.2). The SQoLM total score improved in both groups (A:16 ± 2,3 vs 33 ± 4,1 and B: 16 ± 3,4 vs 31 ± 2,1). CONCLUSION The treatment twice a day with "Tradamixina" for 2 months improved libido in elderly men without side effects of Tadalafil.

Abstract
Introduction We studied the possible correlation between age, testosterone deficiency, cavernosal fibrosis and erectile dysfunction (ED). Methods 47 patients with ED were enrolled between September 2010 and October 2011. IIEF-EF score, NPTR test using the Rigiscan method, total and free testosterone levels, and cavernosum biopsy were carried out on all patients. Patients aged 65 or over were defined as Old Age (OA) while patients under 65 were defined Young age (YA). The strength of the relationships found was estimated by Odds Ratio. Results 74% of patients with values of over 52% collagen fibers in the corpora cavernosa were found to have organic ED. A significant difference was found in age, percentage of collagen fibers, testosterone levels between patients with Positive Rigiscan (PR) and Negative Rigiscan (NR). Hypotestosteronaemia increased the risk of ED with PR (OR: 21.4, 95% CI: 20.2-22.6) and in both young age patients (OR: 4.3, 95% CI: 2.4-6.2) and old age patients (OR: 15.5, 95% CI: 13.4-17.6). Moreover cavernosal fibrosis increased the risk of ED with PR in both young age patients (OR: 8.2, 95% CI: 6.4-10.0 and old age patients (OR: 24.6, 95% CI: 20.8-28.4). Conclusions This study demonstrates a strong association among age, testosterone deficiency, cavernosal fibrosis and ED with PR. Age, testosterone deficiency and cavernosal fibrosis are potentially correctable factors of cavernosal fibrosis and organic ED. Further, prospective studies are needed to evaluate if testosterone treatment, alone or in association with PDE5 inhibitors, may lower the risk of cavernosal fibrosis or decrease the severity the fibrosis in ED patients.

Abstract
BACKGROUND Lower urinary tract symptoms (LUTS) are associated with great emotional costs to individuals and substantial economic costs to society. This study seeks to evaluate the effect of a new natural compound "Tradamixina plus Serenoa Repens" in order to improve lower urinary tract symptoms. METHODS 100 patients (≥ 45 years) who had had LUTS/BPH for >6 mo at screening and with IPSS -The international Prostate symptom scores- ≥ 13 and maximum urinary flow rate (Qmax) ≥ 4 to ≤ 15 ml/s. were recruited. The compound "Tradamixina plus Serenoa Repens" (80 mg of Alga Ecklonia Bicyclis, 100 mg of Tribulus Terrestris and 100 mg of D-Glucosamine and N-Acetyl-D-Glucosamine plus 320 mg of Serenoa Repens) was administered daily for 2 months. At visit and after 60 days of treatment patients were evaluated by means of detailed medical urological history, clinical examination, laboratory investigations (total PSA), and instrumental examination like urolfowmetry. Efficacy measures included IPSS-International Prostate Sympto, BPH Impact Index (BII), Quality-of-Life (QoL) Index. Measures were assessed at baseline and end point (12 wk or end of therapy) and also at screening, 1 and 4 wk for IPSS, and 4 wk for BII. Statistical significance was interpreted only if the results of the preceding analysis were significant at the 0.05 level. RESULTS After 2 months of treatment the change from baseline to week 12 relative to "Tradamixina plus Seronea Repens" in total IPSS and Qol was statistically significant. Differences from baseline in BII were statistically significant for "Tradamixina plus Seronea Repens" above all differences in BII were also significant at 4 wk (LSmean ± SE: -0.8 ± 0.2). In the distribution of subjects over the PGI-I and CGI-I response categories were significant for"Tradamixina plus Seronea Repens" (PGI-I: p = 0.001; CGI-I). We also observed a decrease of total PSA. CONCLUSION The daily treatment with a new compound "Tradamixina plus Serenoa Repens" for 2 months improved the male sexual function , it improved the bother symptoms which affect the patient's quality of life , improved uroflowmetric parameters, and we also observed a decrease of serum PSA level.

Abstract
BACKGROUND Peyronie's disease is an acquired connective tissue disorder of the penile tunica albuginea with fibrosis and inflammation. The disease produces palpable plaques, penile curvature and pain during erections. Patients report negative effects in four major domains: physical appearance and self-image, sexual function and performance. These changes damage sexual life and compromise the quality of life. Our objective is to review the patient's sexual life after penile tunical plicature using the International Index of Erectile Function (IIEF) and the Sexual Encounter Profile (SEP) questionnaires. METHODS A total of 47 patients with Peyronie's disease (PD) were enrolled at our urology department and they underwent correction of penile deviation between February 2009 and March 2010. Mean patient age was 56 years and mean follow-up was 24 months. Patients with painless PD plaque with no progression in angulation for at least 12 months were chosen for surgery. They underwent a penile tunical plication.IIEF and SEP questionnaire were administered to all patients. RESULTS Of all treated patients, 94% were able to insert their penis in the partner's vagina (p<0.01; SEP question 2), compared with 62% preoperatively and 90% of them was satisfied overall with the sexual intercourse (p<0.01; SEP question 5) .Patients had a significantly higher endpoint and a greater change from baseline for the remaining SEP questions related to achievement of an erection, satisfaction of erection hardness (SEP questions 1 and 4; p < 0:001).We reported a significant improvement in the IIEF scores (from a baseline total score of 25.2 +/- 3.2 to a final score of 38.3 +/- 5.2; P<0.01). It resulted in significantly higher endpoint IIEF scores across all five IIEF domains: Erectile Function, Intercourse Satisfaction, Orgasmic Function, Sexual Desire and Overall Satisfaction. The main complaint was penile shortening (28 patients, 60%), feeling of the suture during flaccidity and tumescence (37 patients, 80%). CONCLUSION Patient quality of life improved after surgery thanks to the improvement of their sexual life. The complications are unimportant and few bother symptoms are reported. The significant improvement in erectile function was also supported by IIEF and SEP questionnaire data. Nowadays tunical plication is a safe, advantageous and useful technique to treat patients suffering of Peyronie's disease.

Abstract
BACKGROUND Over the past years laser technology has played a predominant role in prostate surgery, for the treatment of benign prostate hypertrophy (BPH). Various laser devices have been introduced in clinical practice, showing good results in terms of complications and urodynamic outcomes efficacy compared with TURP and Open Prostatectomy.In this study we describe the efficacy and the safety profile of a novel laser technique, ThuLEP (Thulium Laser Enucleation of Prostate) that permits a complete anatomical endoscopic enucleation of prostatic adenoma independently to prostate size. METHODS 148 patients with a mean age of 68.2 years were enrolled between September 2009 and March 2012 (36 months), and treated for BPH with ThuLEP. Every patient was evaluated at base line according to: Digital Rectal Examination (DRE), prostate volume, Post-Voided volume (PVR), International Prostate Symptoms Score (I-PSS), International Index of Erectile Function-5 (IIEF-5), Quality of Life (QoL), PSA values, urine analysis and urine culture, uroflowmetry. The same evaluation was conducted after a 12 month follow-up. ThuLEP was performed by 2 expert surgeons. RESULTS Our data showed a better post-operative outcome in terms of catheter removal, blood loss, TURP syndrome, clot retention and residual tissue compared to large series of TURP and OP. Only 1.3% of patients had bladder wall injury during morcellation. I-PSS, Qmax, Prostate Volume, QoL and PVR showed a highly significant improvement at 12 month follow-up in comparison to preoperative assessment. CONCLUSION ThuLEP represent an innovative option in patients with BPH. It is a size independent surgical endoscopic technique and it can be considered the real alternative, at this time, to TURP and even more to Open Prostatectomy for large prostate, with a complete removal of adenoma and with a low complication rate.

Abstract
GW196771 is a potent antagonist of the modulatory glycine site of the N-methyl-D-aspartate (NMDA) receptor exhibiting outstanding in vivo profile in different animal models of chronic pain. With the aim to maximize the drug delivery to the target organs a suitable "pro-drug approach" was attempted; in this regards two conjugates of GW196771 with nutrients actively transported into the brain, namely adenosine and glucose, were prepared and investigated. These compounds, were evaluated in vitro in terms of their stability in rat plasma and in vivo on rats. Although an improvement was observed in terms of brain penetration of the esters vs. the parent compound, the amount of the latter did not increase significantly, probably due to some degradation events in the brain, different from the expected ester hydrolysis, resulting in a reduced availability of GW196771.

Abstract
A direct injection column-switching HPLC method was developed and validated for quantification of sanfetrinem in rat and dog plasma. Following dilution with buffer, samples were directly injected onto the system. The analyte was retained in an enrichment column while endogenous plasma components were eluted to waste. Sanfetrinem was then back-flushed to the analytical column for separation and quantification with an ultraviolet detector. Sample batch size was increased by adding a washing phase of the enrichment column and by alternating the injections between two enrichment columns. The method is very simple and sample preparation is minimal. The method has been fully validated and shown to be specific, accurate and reproducible.

Abstract
The role of iron-dependent oxidative metabolism in protecting the oxidable substrates contained in mature adipocytes is still unclear. Because differentiation increases ferritin formation in several cell types, thereby leading to an accumulation of H-rich isoferritins, we investigated whether differentiation affects iron metabolism in 3T3-L1 pre-adipocytes. To this aim, we evaluated the expression of the genes coding for the H and L ferritin subunits and for cytoplasmic iron regulatory protein (IRP) during the differentiation of 3T3-L1 cells in adipocytes induced by the addition of isobutylmethylxanthine, insulin, and dexamethasone. Differentiation enhanced ferritin formation and caused overexpression of the H subunit, thus altering the H/L subunit ratio. Northern blot analysis showed increased levels of H subunit mRNA. A gel retardation assay of cytoplasmic extract from differentiated cells, using an iron-responsive element as a probe, revealed enhanced an RNA binding capacity of IRP1, which correlated with the increase of IRP1 mRNA. The observed correlation between differentiation and iron metabolism in adipocytes suggests that an accumulation of H-rich isoferritin may limit the toxicity of iron in adipose tissue, thus exerting an antioxidant function.

Oxalomalate, a competitive inhibitor of aconitase, modulates the RNA-binding activity of iron-regulatory proteins. Biochem J 2000; 348 Pt 2:315-20.

Abstract
We investigated the effect of oxalomalate (OMA, alpha-hydroxy-beta-oxalosuccinic acid), a competitive inhibitor of aconitase, on the RNA-binding activity of the iron-regulatory proteins (IRP1 and IRP2) that control the post-transcriptional expression of various proteins involved in iron metabolism. The RNA-binding activity of IRP was evaluated by electrophoretic mobility-shift assay of cell lysates from 3T3-L1 mouse fibroblasts, SH-SY5Y human cells and mouse livers incubated in vitro with OMA, with and without 2-mercaptoethanol (2-ME). Analogous experiments were performed in vivo by prolonged incubation (72 h) of 3T3-L1 cells with OMA, and by injecting young mice with equimolar concentrations of oxaloacetate and glyoxylate, which are the precursors of OMA synthesis. OMA remarkably decreased the binding activity of IRP1 and, when present, of IRP2, in all samples analysed. In addition, the recovery of IRP1 by 2-ME in the presence of OMA was constantly lower versus control values. These findings suggest that the severe decrease in IRP1 RNA-binding activity depends on: (i) linking of OMA to the active site of aconitase, which prevents the switch to IRP1 and explains resistance to the reducing agents, and (ii) possible interaction of OMA with some functional amino acid residues in IRP that are responsible for binding to the specific mRNA sequences involved in the regulation of iron metabolism.

Abstract
OBJECTIVE AND DESIGN To develop a method for the detection of human T-cell lymphotropic virus type I (HTLV-I) in archival biopsy specimens. A polymerase chain reaction-based gene amplification method was developed to detect HTLV-I proviral DNA in paraffin-embedded specimens. The specificity of the polymerase chain reaction products was controlled by Southern blot analysis using a nested oligonucleotide probe and by nucleotide sequencing. The nucleophosmin gene and the T-cell receptor-gamma gene were used as controls for the integrity and adequacy of total DNA and T-cell DNA, respectively. This study was conducted with patients referred to an academic medical center. Biopsy specimens were obtained from lesional skin or lymph node from Japanese patients with HTLV-I seropositive adult T-cell leukemia/lymphoma. The main outcome measure was the ability to detect HTLV-I pX region proviral DNA. RESULTS Comparative analysis of DNA extracted from fresh samples of the HTLV-I infected MT4T-cell line demonstrated that formalin fixation and paraffin embedding resulted in a 100-fold reduction in sensitivity of the assay. Nevertheless, HTLV-I pX sequences were still readily detectable in paraffin-embedded samples of MT4 T cells and adult T-cell leukemia/lymphoma specimens. Both formalin and B5 fixation were suitable for the assay that was 100% specific for HTLV-I-infected tissues. CONCLUSIONS The use of this method should greatly facilitate investigation of the role of HTLV-I in human diseases by allowing analysis of a wide variety of archival tissue specimens. In addition, the controls designed for the current study can be used in a variety of other polymerase chain reaction-based studies of T cells to ensure against false-negative results caused by DNA degradation or inadequate T-cell density.

Abstract
The authors report the results acquired from 1981 to 1985 using the Angelchik prosthesis in 22 patients with reflux oesophagitis resisting medical therapy for more than 6 months. Clinical evaluation has been done using Visick scale, as modified by Deakin. Clinical and instrumental controls have been done at 1 month, 12 months and 5-10 years after the operation. Intraoperative mortality and morbidity were zero. Complications directly related to the operation were: transitory dysphagia in 4 cases, persistent dysphagia in 3 cases, transitory gas bloat syndrome in 1 case and persistent gas bloat syndrome in another, persistent stenosis in 1 case and prosthesis dislocation in 6 cases. Clinical results were satisfactory (success rate: 90.9%) only in patients with a short term follow-up (30 days). The full rate of success has come down to 84.2% and 66.6% in patients having follow-ups respectively of 1 year and 5-10 years. The results are truly disappointing and the authors conclude that this procedure is not to be employed.

Abstract
Only Flower (1976) has reported an isolated obstruction of the left brachiocephalic venous trunk following the observation of a unilateral distension of the left superior jugular vein secondary to compression of the homolateral innominate vein during a type I dissecting aneurysm of the aorta. The rarity of the finding is the reason for the report of two cases of isolated thrombosis of the venous trunk in question observed almost simultaneously some 19 months earlier. In both cases it was possible to identify the aetiopathogenic causes as congenital or acquired constriction of the "aortosternal strait" associated with thrombophilic alteration to the blood coagulation system.

Abstract
The complex diagnostic procedure involved in a case of splenic abscess in a young drug addict as a result of septicaemia caused by streptococcus fascalis is described and discussed with an examination of the criteria in support of a more aggressive approach to the removal of septic foci in such patients with AIDS. It is concluded that such criteria are valid even when, as in the case described, splenectomy further depresses the immune system.

Abstract
Histochemical techniques were employed to determine acid phosphatase and alpha-naphthylesterase activities in follicular cells from the mucosa of surgically removed human appendixes. These very reactive cells are found in two areas: in the middle of the light centre and in the surroundings of this centre. The former are globose, arranged with a certain degree of order, and have a reticular anchorage that does not appear to be particularly affected by the physiological and pathological events that occur in the appendix, whereas those of the border vary in number or may even be absent. They have an elongated shape and are also anchored in a reticulum that in this case is more consistent. The result is that in certain forms of appendiceal disease the pale centre of the follicle is closed in a kind of shell formed of very reactive cells. The identification and significance of these two groups of cells of the light centre are discussed.

Abstract
When the cause of oesophagitis has been discovered, patients for whom surgical management is impossible may be successfully treated by improving oesophageal peristalsis, increasing the tone of the LES, and speeding up the emptying of the stomach. The best results are obtained in peptic oesophagitis, since the latest secretion-inhibiting drugs ensure constant reduction of the acidity of the gastric juice, as has been demonstrated by continuous pH monitoring.

Abstract
Results obtained by using Angelchik and Cohen's ring prosthesis in 10 patients with hernia due to sliding through the oesophageal hiatus of the diaphragm are reported. In 8 patients, the ring was perfectly tolerated and performed its antireflux and hernia containment functions. In the 2 other patients, however, the prosthesis rose to the mediastinum, causing hernia to recur in one case and leading to recurrence of symptomatology in the other.

Abstract
Personal clinical experience and the results obtained in the treatment of patients suffering from severe hepatic insufficiency observed in the last seven years, out of a total of some 200 cases, are reported. The modalities employed in the application of intensive basic care and special treatment in 50 cases of initial or clear hepatic coma of various aetiological origin are reviewed. Whereas basic treatment involves more purely medical measures, such as reintegrative and nutritional treatment by the venous route, activation of renal function, the prophylaxis of infectious complications and reinfusion of ascitic fluid, that applied to cases of clear coma involves a more properly surgical technique. It makes use of an original biological clarification technique in extracorporeal circulation by means of isolated and perfused heterologous liver, and an isovolaemic exsanguinotransfusion technique. Indications and features are illustrated in detail.
