Abstract
The first measurement of the cross section for incoherent photonuclear production of J/ψ vector mesons as a function of the Mandelstam |t| variable is presented. The measurement was carried out with the ALICE detector at midrapidity, |y|<0.8, using ultraperipheral collisions of Pb nuclei at a center-of-mass energy per nucleon pair of sqrt[s_{NN}]=5.02 TeV. This rapidity interval corresponds to a Bjorken-x range (0.3-1.4)×10^{-3}. Cross sections are given in five |t| intervals in the range 0.04<|t|<1 GeV^{2} and compared to the predictions by different models. Models that ignore quantum fluctuations of the gluon density in the colliding hadron predict a |t| dependence of the cross section much steeper than in data. The inclusion of such fluctuations in the same models provides a better description of the data.

Measurements of Groomed-Jet Substructure of Charm Jets Tagged by D^{0} Mesons in Proton-Proton Collisions at sqrt[s]=13 TeV. PHYSICAL REVIEW LETTERS 2023; 131:192301.

Abstract
Understanding the role of parton mass and Casimir color factors in the quantum chromodynamics parton shower represents an important step in characterizing the emission properties of heavy quarks. Recent experimental advances in jet substructure techniques have provided the opportunity to isolate and characterize gluon emissions from heavy quarks. In this Letter, the first direct experimental constraint on the charm-quark splitting function is presented, obtained via the measurement of the groomed shared momentum fraction of the first splitting in charm jets, tagged by a reconstructed D^{0} meson. The measurement is made in proton-proton collisions at sqrt[s]=13 TeV, in the low jet transverse-momentum interval of 15≤p_{T}^{jet ch}<30 GeV/c where the emission properties are sensitive to parton mass effects. In addition, the opening angle of the first perturbative emission of the charm quark, as well as the number of perturbative emissions it undergoes, is reported. Comparisons to measurements of an inclusive-jet sample show a steeper splitting function for charm quarks compared with gluons and light quarks. Charm quarks also undergo fewer perturbative emissions in the parton shower, with a reduced probability of large-angle emissions.

Measurement of the Lifetime and Λ Separation Energy of _{Λ}^{3}H. PHYSICAL REVIEW LETTERS 2023; 131:102302.

Abstract
The most precise measurements to date of the _{Λ}^{3}H lifetime τ and Λ separation energy B_{Λ} are obtained using the data sample of Pb-Pb collisions at sqrt[s_{NN}]=5.02 TeV collected by ALICE at the LHC. The _{Λ}^{3}H is reconstructed via its charged two-body mesonic decay channel (_{Λ}^{3}H→^{3}He+π^{-} and the charge-conjugate process). The measured values τ=[253±11(stat)±6(syst)] ps and B_{Λ}=[102±63(stat)±67(syst)] keV are compatible with predictions from effective field theories and confirm that the _{Λ}^{3}H structure is consistent with a weakly bound system.

Enhanced Deuteron Coalescence Probability in Jets. PHYSICAL REVIEW LETTERS 2023; 131:042301.

Abstract
The transverse-momentum (p_{T}) spectra and coalescence parameters B_{2} of (anti)deuterons are measured in p-p collisions at sqrt[s]=13 TeV for the first time in and out of jets. In this measurement, the direction of the leading particle with the highest p_{T} in the event (p_{T}^{lead}>5 GeV/c) is used as an approximation for the jet axis. The event is consequently divided into three azimuthal regions, and the jet signal is obtained as the difference between the toward region, that contains jet fragmentation products in addition to the underlying event (UE), and the transverse region, which is dominated by the UE. The coalescence parameter in the jet is found to be approximately a factor of 10 larger than that in the underlying event. This experimental observation is consistent with the coalescence picture and can be attributed to the smaller average phase-space distance between nucleons in the jet cone as compared with the underlying event. The results presented in this Letter are compared to predictions from a simple nucleon coalescence model, where the phase-space distributions of nucleons are generated using pythia8 with the Monash 2013 tuning, and to predictions from a deuteron production model based on ordinary nuclear reactions with parametrized energy-dependent cross sections tuned on data. The latter model is implemented in pythia8.3. Both models reproduce the observed large difference between in-jet and out-of-jet coalescence parameters, although the almost flat trend of the B_{2}^{Jet} is not reproduced by the models, which instead give a decreasing trend.

Thermographic ocular temperature correlated with rectal temperature in cats. J Therm Biol 2021; 102:103104.

Abstract
Body temperature reflects the animal health and/or disease conditions. During clinical examination, temperature measurement is a basic step in veterinary medicine. The conventional method used is the rectal thermometry, particularly stressful in some subjects, especially for cats. A less stressful alternative method, such as infrared thermal imaging camera, is used in various fields of medicine for diagnosis, prognosis and correct therapeutic approaches. To evaluate the usefulness of infrared thermal imaging for the assessment of ocular temperature, twenty cats of different breeds (European, Siamese and Persian, 4-6 years old, mean body weight 4.3 ± 0.30 Kg) were enrolled in the study. In order to evaluate the applicability of the ocular temperature assessment through thermal imaging as a tool for measuring the animal's body temperature, the obtained values were compared with the rectal temperature values recorded in each cat by means of a digital thermo-camera. There were no differences between left and right eye; and a difference of about 1.19 °C between the ocular and rectal temperature value was recorded (p < 0.0001). Rectal and ocular temperatures were positively correlated (p < 0.0001; r = 0.93). In conclusion, we show that ocular temperature is an alternative method for body temperature measurement that can be used in clinical evaluation of cats, especially in cases where rectal temperature recording is not possible.

Abstract
Erectile dysfunction (ED) following transperineal prostate biopsy (TPB) was prospectively evaluated. From January 2011 to January 2014, 1050 patients were submitted to TPB: 18 core (extended TPB) in 610 cases, 28 core (saturation TPB) in 360 cases and 32 core (saturation plus magnetic resonance imaging (MRI) targeted TPB) in 210 cases. The indications for biopsy were increasing prostate-specific antigen (PSA) or PSA>10 ng ml(-1). All patients were prospectively evaluated with the 5-item version of the International Index of Erectile Function (IIEF-5) at time zero and at 1, 3 and 6 months from TPB. Prostate cancer was diagnosed in 385/1050 (36.6%) patients; 560 men (350 vs 110 vs 100) having benign histology and normal sexual activity also completed the study. Overall, IEEF-5 score at time zero and at 1, 3 and 6 months did not significantly worsen (P>0.05); in detail, at 1 month from biopsy 15 extended TPB (4.2%) vs 7 saturation TPB (6.4%) vs 7 saturation plus MRI targeted TPB (7%) men referred mild ED that disappeared after 3 months. Irrespective of method (18 vs 28 vs 32 core) TPB did not significantly worsen erectile function at 3-6 months from the procedure.

Abstract
Differences in free fatty acids (FFAs) chemical composition of insects may be responsible for susceptibility or resistance to fungal infection. Determination of FFAs found in cuticular lipids can effectively contribute to the knowledge concerning insect defense mechanisms. In this study, we have evaluated the susceptibility of three species of cockroaches to the entomopathogenic fungi Metarhizium anisopliae (Metschnikoff) Sorokin by topical application. Mortality due to M. anisopliae was highly significant on adults and nymphs of Blattella germanica L. (Blattodea: Blattellidae). However, mortality was faster in adults than in nymphs. Adults of Blatta orientalis L. (Blattodea: Blattidae) were not susceptible to the fungus, and nymphs of Blaptica dubia Serville (Blattodea: Blaberidae) were more susceptible to the fungus than adults. The composition of cuticular FFAs in the three species of cockroaches was also studied. The analysis indicated that all of the fatty acids were mostly straight-chain, long-chain, saturated or unsaturated. Cuticular lipids of three species of cockroaches contained 19 FFAs, ranging from C14:0 to C24:0. The predominant fatty acids found in the three studied species of cockroaches were oleic, linoleic, palmitic, and stearic acid. Only in adults of Bl. orientalis, myristoleic acid, γ-linolenic acid, arachidic acid, dihomolinoleic acid, and behenic acid were identified. Lignoceric acid was detected only in nymphs of Bl. orientalis. Heneicosylic acid and docosahexaenoic acid were identified in adults of Ba. dubia.

Abstract
Basal levels of oxidants are indispensible for redox signaling to produce adaptive cellular responses such as vitagenes linked to cell survival; however, at higher levels, they are detrimental to cells, contributing to aging and to the pathogenesis of numerous age-related diseases. Aging is a complex systemic process and the major gap in aging research reminds the insufficient knowledge about pathways shifting from normal "healthy" aging to disease-associated pathological aging. The major complication of normal "healthy" aging is in fact the increasing risk of age-related diseases such as cardiovascular diseases, diabetes mellitus, and neurodegenerative pathologies that can adversely affect the quality of life in general, with enhanced incidences of comorbidities and mortality. In this context, global "omics" approaches may help to dissect and fully study the cellular and molecular mechanisms of aging and age-associated processes. The proteome, being more close to the phenotype than the transcriptome and more stable than the metabolome, represents the most promising "omics" field in aging research. In the present study, we exploit recent advances in the redox biology of aging and discuss the potential of proteomics approaches as innovative tools for monitoring at the proteome level the extent of protein oxidative insult and related modifications with the identification of targeted proteins.

Abstract
Major depression is one of the leading causes of disabling condition worldwide and its treatment is often challenging and unsatisfactory, since many patients become refractory to pharmacological therapies. Transcranial magnetic stimulation (TMS) is a noninvasive neurophysiological investigation mainly used to study the integrity of the primary motor cortex excitability and of the cortico-spinal tract. The development of paired-pulse and repetitive TMS (rTMS) paradigms has allowed investigators to explore the pathophysiology of depressive disorders and other neuropsychiatric diseases linked to brain excitability dysfunctions. Repetitive transcranial magnetic stimulation has also therapeutic and rehabilitative capabilities since it is able to induce changes in the excitability of inhibitory and excitatory neuronal networks that may persist in time. However, the therapeutic effects of rTMS on major depression have been demonstrated by analyzing only the improvement of neuropsychological performance. The aim of this study was to investigate cortical excitability changes on 12 chronically-medicated depressed patients (test group) after rTMS treatment and to correlate neurophysiological findings to neuropsychological outcomes. In detail, we assessed different parameters of cortical excitability before and after active rTMS in the test group, then compared to those of 10 age-matched depressed patients (control group) who underwent sham rTMS. In line with previous studies, at baseline both groups exhibited a significant interhemispheric difference of motor cortex excitability. This neurophysiological imbalance was then reduced in the patients treated with active rTMS, resulting also in a clinical benefit as demonstrated by the improvement in neuropsychological test scores. On the contrary, after sham rTMS, the interhemispheric difference was still evident in the control group. The reported clinical benefits in the test group might be related to the plastic remodeling of synaptic connection induced by rTMS treatment.

Abstract
Osteoblastoma is a rare benign tumor of bone that accounts for approximately 1% of primary skeletal neoplasms, with around 90% of cases diagnosed in the second and third decades of life. Cervical spine is an usual localization of osteoblastoma. The main clinical manifestation in case of cervical spine location is a progressive and resistant pain, possibly accompanied by stiffness, scoliosis or other ailments, including severe neurological deficits. Owing to a non-specific clinical presentation of osteoblastoma, the delay in diagnosis is common. Osteoblastomas may have an aggressive behavior, tend to enlarge and damage the bone and adjacent structures. The treatment of choice is, therefore, a wide and complete surgical excision of the lesion in order to achieve full recovery and prevent recurrence or, in some cases, malignant transformation. In the case of persistent neck pain, not readily relieved by aspirin and possibly accompanied by stiffness, scoliosis or neurological deficits, especially in young subjects, osteoblastoma of cervical spine may be one of the diagnostic options to be considered, in order to avoid delay in diagnosis. We report the case of a 41-year-old male affected by cervical spine osteoblastoma causing a lasting neck pain.<br />

Abstract
Transcranial magnetic stimulation (TMS) is the most important technique currently available to study cortical excitability. Additionally, TMS can be used for therapeutic and rehabilitation purposes, replacing the more painful transcranial electric stimulation (TES). In this paper we present an innovative and easy-to-use tool that enables neuroscientists to design, carry out and analyze scientific studies based on TMS experiments for both diagnostic and research purposes, assisting them not only in the practicalities of administering the TMS but also in each step of the entire study's workflow. One important aspect of this tool is that it allows neuroscientists to specify research designs at will, enabling them to define any parameter of a TMS study starting from data acquisition and sample group definition to automated statistical data analysis and RDF data storage. It also supports the diagnosing process by using on-line support vector machines able to learn incrementally from the diseases instances that are continuously added into the system. The proposed system is a neuroscientist-centred tool where the protocols being followed in TMS studies are made explicit, leaving to the users flexibility in exploring and sharing the results, and providing assistance in managing the complexity of the final diagnosis. This type of tool can make the results of medical experiments more easily exploitable, thus accelerating scientific progress.

Abstract
BACKGROUND Vascular damage of frontal-subcortical circuits involved in mood regulation and cognition might be the main contributor to the pathogenesis of late-life depression, and it is linked to poor response to treatment. OBJECTIVE To investigate the relationship between executive dysfunction and outcome of depressive symptoms among elderly patients with subcortical ischemic vascular disease. METHODS Ninety-two elderly patients with white matter lesions (WMLs) or lacunar infarcts (LAs) on brain MRI and depressive symptomatology were consecutively recruited. Depression was rated with the Hamilton Depression Rating Scale (HDRS). Evaluation of executive functions by means of the Stroop color-word test was performed at entry of the study, and WMLs were categorized into mild, moderate or severe. Mood was reevaluated by means of HDRS after the 12th week of pharmacological treatment. RESULTS Psychomotor retardation, difficulties at work, apathy, and lack of insight were the predominant symptoms. Fifty-six patients (62.8%) had a neuroradiological picture of WMLs, while the remaining 33 (37.1%) had LAs. Executive dysfunctions significantly and independently predict poor outcome of depressive symptoms. Patients with the severest WMLs showed not only a greater executive dysfunction, but also a minor response to antidepressant treatment. CONCLUSION This study supports the vascular depression hypothesis. WMLs are of crucial clinical relevance as they are linked with cognitive symptoms and poor antidepressant outcome.

Abstract
OBJECTIVE To report a case of local recurrence 16 years after radical nephrectomy; to analyse literature data concerning, treatment and prognosis. METHODS/RESULTS We report a case of local recurence associated with caval trombosis who was underwent an en-bloc resection of vena cava along with pericaval lesion and caval replacement with PTFE prosthesis. The Authors reviewed and analysed literature data. CONCLUSIONS Local recurrence after radical nephrectomy is rare as it is reported only in 2-4% of patients. This condition is even rarer beyond 10 years especially if associated with caval trombosis. A case of isolated local recurrence of renal cell carcinoma with caval involvement 16 years after radical nephrectomy is described herein. To the best of our knowledge, this is the first case reported in literature. This case highlights the opportunity of a periodic checkup of patients submitted to radical nephrectomy, even many years after surgery.

Abstract
PURPOSE The aim of this study was to evaluate the study of intra- and extra-biliary ducts by contrast-enhanced colour-Doppler in patients who have undergone laparoscopic cholecystectomy. MATERIALS AND METHODS Contrast-enhanced colour-Doppler US was performed in 15 patients who had undegone laparoscopic cholecystectomy. The US contrast agent was introducted into the Kehr or Pedinelli tube to allow visualisation of the bile ducts and duodenum. RESULTS The colour-Doppler study enabled visualisation of the contrat agent in the intra- and extra-hepatic bile ducts and in the duodenum in all patients, thereby permitting the accurate study of the post-operative course. The data obtained were confirmed by conventional radiology. CONCLUSIONS The advantages of this US ultrasound technique are the complete absence of ionising radiation and no intolerance to the US contrast agent. This technique could therefore be used in selected patients as an alternative to trans-Kehr and trans-Pedinelli cholangyography.

Abstract
Purpose. To find a predictor of extraprostatic extension in clinically localized prostate cancer (PCa), preoperative ultrasound-guided prostate needle biopsies and clinicopathological data were reviewed. Materials and Methods 102 consecutive patients (median age 63 years) with serum PSA ≤10 ng/mL who underwent radical retropubic prostatectomy were included. Preoperative prostate biopsies according to an extended protocol were performed and whole-mount prostatectomy specimens were processed. One or more of the following biopsy variables were considered predictive of locally andvanced PCa: more than 2/12 cancer-positive cores, total percentage of cancer (TPC) >20%, greatest percentage of cancer (GPC) >50%, bilateral PCa, presence of cancer in both lateral portions, Gleason score >6. Results Only 32/102 (31.4%) specimens showed an organ-confined PCa; the remaining were pT3a in 30 (29.4%) cases, pT3b in 6 (5.9%) and pT2–T3 with positive surgical margins in 34 (33.3%). Quantitative histology predicted an organ-confined PCa in 41.2% of patients. In all 102 patients and in 56 with T1c clinical stage, the positive predictive value (PPV) and negative predictive value (NPV) of biopsy findings, to predict an organ confined PCa, was 81.2 vs 92% and 91.6 vs 93.4%, respectively. The PPV and NPV to predict a locally advanced PCa was 92.8 and 86.5%, respectively. Conclusions Quantitative histology seems to be helpful for locally staging of PCa in patients with T1c clinical stage and PSA ≤10 ng/mL.

Abstract
AIM This paper reports personal experience relating to the use of "static" and "permicturition" prostatic transrectal ultrasonography and urethral ultrasonography in the imaging diagnosis of obstructed patients. METHODS Between January 1996 and January 1998 we selected 96 consecutive patients aged between 25 and 73 years old (mean 54 years) with symptoms of obstructive dysuria with pathological uroflowmetry and pressure/flow rates (Qmax ranging between 5-12 ml/sec and URA between 34-81). Eighteen of the patients selected had previously undergone prostate surgery for benign pathologies. All patients underwent a standard and permicturition transrectal ultrasonography and urethral ultrasonography using a retrograde approach. The results were compared with those obtained by retrograde urethrocystography and urethrocystoscopy, regarded as the "gold standard" for the diagnosis of urethral obstruction. RESULTS Sixty-three (65.5%) patients were able to execute the permicturition phase, but only 54 (56.2%) reported that the test was indicative of "real urination", whereas retrograde urethral ultrasonography was well tolerated in all cases and easy to accomplish. In 19 (20%) patients (6 of whom had undergone prostate surgery and 13 were suffering from urethral stenosis), "major" organic alterations responsible for urethral obstruction were observed with the combined use of these ultrasonographic methods. These were not evident using static transrectal ultrasonography and increased the diagnostic sensitivity from 80 to 98%. CONCLUSIONS We feel that an increasingly complete ultrasonographic study of the lower urinary tract is necessary, above all in obstructed patients. This can be achieved using permicturition and urethral transrectal ultrasonography, ensuring an accurate diagnosis and optimising health expenditure.

Abstract
OBJECTIVE To study the impact of severe head injury on both basal pituitary hormone secretion and the response to exogenous synthetic hypothalamic releasing factors (TRH and GHRH) in order to evaluate sequential changes in the central control of hypophyseal secretion in the days following head injury. DESIGN Prospective clinical study PATIENTS 21 comatose male patients with head injuries, each intubated and ventilated, intensively monitored and having no previous endocrine problems. MEASUREMENTS AND RESULTS The GH and PRL responses to TRH (200 microg iv), and the GH and PRL responses to GHRH (50 microg iv) were evaluated, respectively, on the days 1 and 16 and on days 2, 7and 15 after admission. Daily blood samples were also collected for GH, PRL, TSH, T3 and T4 evaluation. In the basal samples taken on days 2, 7 and 15, IGF-I and cortisol were also determined. Nitrogen balance was assessed daily. On the day 1, TRH increased GH levels from 9.8 +/- 2.2 to 22.4 +/- 6.5 mU/l but failed to induce GH release on day 16. The PRL response to TRH was normal. The GH peak response to GHRH was normal on the day 2 (35.7 +/- 13.9 mU/l), but was increased on days 7 and 15 (68.3 +/- 10.7 mU/l on day 7; 73.8 +/- 9.2 mU/l on day 15, P < 0.01 vs. day 2). We found a significant PRL response to GHRH during the whole period of observation. In the daily evaluation, nitrogen balance was negative in all patients from the day 1 to 5. On average, all patients reached a positive nitrogen balance on the day 8. Compared to the day 2, a statistical increase in IGF-I concentration was observed on days 7 and 15. CONCLUSIONS The evaluation of pituitary dynamics in the acute phase of a severe injury demonstrates an alteration of GH and PRL secretion, which correlate with the aminergic and/or peptidergic derangements. Taken together, our data suggest augmented tone of both GHRH and somatostatin in the very acute phase, while an imbalance of releasing factors is hypothesized in the following days. The metabolic consequences of this neuroendocrine pattern could be advantageous in the rapid recovery from the cascade of events produced by the trauma, as documented by the increase in IGF-1 levels and the positive nitrogen balance.

Abstract
Urogenital prolapse and urinary incontinence secondary to multiple defects of the pelvic floor (cystocele caused by lateral and central defect of the pubocervical fascia, hysterocele, rectocele) may also be successfully treated by vaginal approach only. From October ‘95 to September ‘97, 78 women underwent colpohysterectomy, Lahodny bladder suspension and perineoplasty and in 15 of them the vaginal cupola was anchored to the right sacrospinous ligament. In another 3 women Lahodny's procedure was associated with just perineoplasty, since there was a cystocele caused by lateral and central defect of the pubocervical fascia and a rectocele, while the uterus was fixed in place. Prior to operation the 81 patients underwent a colpocytological exam, pelvic ultrasound, a urodynamic exam with flow pressure study and assessment of the leak pressure with Valsalva manoeuvre, and in the cases of constipation or fecal incontinence, coloproctological investigation. The suprapubic catheter that was always positioned at the end of the operation was on average removed on the 10th day, upon the disappearance of significant post-micturitional residue. There is no micturitional difficulty in any patient. Given the short follow-up, the results are given of the 44 women observed for at least one year, 40 of whom are continent. Recurrent prolapse was found in 8 cases, 2 involving the anterior, 40 the rear and 2 the central wall. No patient has had a return of stress incontinence.

Abstract
A more precise determination of the date of primary rubella infection in pregnancy is obtained by application of the urea denaturation method. Two denaturation buffers containing 6 and 8 M urea were compared for the detection of rubella IgG avidity by enzyme immunoassay. The results demonstrate that IgG avidity detected by 6M urea increases more rapidly, from 16% on the third day to 51% on the 46th day after the rash, than that obtained by 8 M urea, from 13 to 36%. The specific rubella IgG avidity detected by 6 M urea denaturation buffer increased significantly in paired sera obtained at an interval of 15 days. The same samples did not show any significant increase of IgG avidity when an 8 M urea denaturation buffer was used. The use of a mild denaturant such as 6 M urea indicates the presumptive date of primary rubella infection in pregnancy within 2 months of sampling.

Abstract
This work deals with our experience of a programme of early diagnosis of prostate cancer carried out on patients suffering from dysuria through rectal-digital examination (EDR), hematic dosage of PSA (IRMA COAT-A-COUNT DPC) and transrectal echtomography. We have also quantified the costs and verified which methods, either single or combined with other methods, are most advantageous as regards costs/benefits. From Jan 1991 to Jan 1995 306 of 1185 patients (25.8%) underwent prostate biopsy by means of transperineal echograph with gauge 18 needles as in Hodge's technique. Histologic examination revealed prostate adenocarcinoma in 81 (26.5%) cases, benign prostate hypertrophy in 196 (64%), acute and/or chronic phlogosis in 26 (8.5%) and granulomatosic prostatitis in 3 (1%). The diagnostic sensitivity, preciseness and accuracy were, respectively, 92.5%, 78.3%, 79.3% for the EDR, 80.2%, 93.3% and 90% for PSA with cut-off 10 ng/ml, 91% 78.3%, and 90% for the PSA with cut-off 4 ng/ml, 100%, 30.3% and 48.6% for the echograph, 98.8%, 60% and 77% for EDR+PSA (cut-off 4 ng/ml), 98.8%, 65.8 and 79.9% for EDR+PSA (cut-off 10 ng/ml), 100%, 22% and 64.2% for EDR+echograph, 100%, 20% and 62.9% for echograph+PSA (cut-off 4 ng/ml), 100%, 26.6% and 64.9% for echograph+PSA (cut-off 10 ng/ml). We calculated that a programme of early diagnosis using the three methods, if completely at the patient's expense, would cost 207.000-437.000 lire (average 322.000) per patient for a total of 245,295,000-517,845,000 (average 381,570,000). An eco-guided prostate biopsy with a histologic examination would cost 250.000-500.000 lire (average 375.000) per patient with a total cost for 306 patients of 76,500,000-153,000,000 (average 114,750,000). We also quantified, in the light of the results reported here, the number of biopsied which would have been necessary if we had used only two methods in the screening and we also estimated the costs. The results reveal that the echograph is not to be considered as a first approach method as it gives a high number of false positive results; in fact if we had excluded it from the screening we would not have ignored any diagnosis of prostate neoplasia and we would have avoided about 141 (46.2%) biopsied with a reduction in health expenditure of 62.1%. On the contrary the EDR and the PSA have a better cost/benefit result: setting the cut-off of the PSA at 4 ng/ml or at 10 ng/ml without varying the diagnostic accuracy, the sensitivity and/or specificity of the method increase respectively. To conclude, we consider the EDR and the serum dosage of PSA necessary and adequate methods in the programme of early diagnosis and screening of prostate neoplasy. The prostate echography should be reserved for cases of doubt (hematic PSA between 4-10 ng/ml etc.) and for the exclusion of needle biopsy. These measures also result in an optimization of health expenditure.

Abstract
From November 1992 to March 1994, in the Gynaecological ward of the Obstetrical and Gynaecological section of Cannizzaro Hospital, 218 patients suffering from urinary stress incontinence (U.S.I.) were observed. Using computerized clinical cards, U.S.I. was found in the 71.79% cases. From the clinical evaluation 38.39% of patients were found to be suffering from 1st degree bladder prolapse, 34.82% from 2nd degree bladder prolapse and 16.97% from, 3rd degree. 9.82% of the patients did not manifest signs of bladder prolapse. Therapy was mainly surgical. Burch colposuspension was carried out on 65 patients. When necessary a total hysterectomy and perineal plastic surgery was carried out. A Perrin-Leger bladder neck suspension was carried out on 10 patients and a Pereyra-Raz on 5. Given the varied aspects of U.S.I., the Authors would conclude that the best results are obtained by combining medical, surgical and rehabilitative treatment.

Abstract
Over the last decade PSA has been widely acknowledged to be a very sensitive and specific marker of prostatic tumour pathologies. This paper reports the authors' experience relating to the use of PSA in the early diagnosis of prostatic heteroplasia on the basis of results obtained in a study performed in 805 dysuric patients who underwent rectal exploration and CAT. Echo-guided prostate biopsy according to Hodge was performed in 212 (26.4%) out of 805 patients and adenocarcinoma was found in 55 cases (25.9%). PSA ranged between 10-198 ng/ml in 42 out of 212 patients, between 4-10 ng/ml in 60, and was below 4 ng/ml in 110. In addition, PSAd was assayed in all patients with PSA < 10 mg/ml. Having established the cutoff of PSA at 10 ng/ml, it was found that some heteroplasia, above all at the initial sage, presented normal PSA blood values. In fact, in 8 cases, equivalent to 14.5% of the neoplasias diagnosed, values were under 4 ng/ml, and in 5 cases, equivalent to 9%, they ranged between 4-10 ng/ml. This finding showed that the threshold value of 10 ng/ml gives PSA a high specificity, but a lower sensitivity in the early diagnosis of prostatic adenocarcinoma. Moreover, the analysis of PSA-density does not significantly allow the diagnosis of a larger number of heteroplasias: in fact, out of 13 cases of adenocarcinoma with PSA < 10 ng/ml, PSAd was only > 0.15 in 2 patients. Therefore, in line with the data reported in the literature, the authors consider that PSA assay represents a sensitive and specific screening method for prostatic tumour pathologies in symptomatic patients, but in order to obtain an early diagnosis, and especially in cases with serum values between 4-10 ng/ml, it must be combined with both rectal exploration and, above all, transrectal scan.

Abstract
In the report we refer to our experience as regards the role of transrectal ultrasonography in the early diagnosis of prostatic heteroplasia based on the results obtained by a research led from January 1991 to January 1995 on 1185 dysuria patients who have been subjected also to a rectal exploration and a serous dosage of PSA. Among the 306/1185 (25.8%) of the patients subjected to prostatic echoguided biopsy sec. Hodge in 238 (77.7%) a hypoechogenic zone on behalf of the periphery of the prostatic parenchyma has been reported. The histological result has pointed out the presence of adenocarcinoma in 81 (26.4%) patients; of benign prostatic hypertrophy in 196 (64%); of acute and/or chronic non specific phlogosis in 26 patients (8.4%) and granulomatosis prostatitis in 3 (1%). The sensibility, the specificity and the diagnostic efficiency of the transrectal ultrasonography in the diagnosis of prostatic heteroplasia have resulted equal, respectively to 100%, to 30.2% and to 48.6%. In 122 patients (66%) the hypoechogenic zone was not pathognomonic of prostatic heteroplasia. Definitely, considering the high sensibility in opposition to the insufficient specificity of the echography, it is our future intention not submit to prostatic biopsy those patients who show only a hypoechogenic zone in absence of pathology EDR and PSA but to monitor them through quarterly clinic checks.
