An assessment of the main metabolic variables of cardiovascular risk in a sample population of workers in Rome.

BACKGROUND: The last few years have seen an increased necessity to assess the cardiovascular risk factors on large samples of the population in Italy. A look at the citizens of a small rural town Brisighella is well known. METHODS: Three hundred and five individuals of average age 40.8 years (+/-8.22), recruited between September 1988 and December 1989 (198 men, 107 women) were taken into consideration. Clinical and instrumental investigations were then performed (intern visits with data obtained from primary anthropometric, otorhinolaryngological and ocular variables, heart X-ray, electrocardiogram). The following analyses were also performed: haemochrome, ESR, uricemia, azotemia, glycemia, AST, ALT, bilirubinemia, protein electrophoresis, triglyceridemia, total cholesterol, HDL cholesterol, creatinine level and urine analysis. Women also received PAP-test. Another variable was lifestyle habits which may be considered a risk for cardiovascular disease. Hygienic and diet suggestions were made. After seven years, in 1997, 100 of these individuals (51 men, 49 women - mean age 42.7+/-6.5 years) were chosen at random and administered the same clinical and laboratory examinations as before. RESULTS: The analysis of the data show average BMI values 24.07+/-2.7 in men and 22.8+/-2.6 in women, inferior to those found in other Italian investigations. We observed an increase of BMI along with age, despite measures of preventive medicine, in married subjects and along with education and occupation level. Mean values of cholesterol level in men increased between the ages 30 and 39 and stabilised after 40 years; in women they increased only after the 5th decade of life. CONCLUSIONS: We observed a direct correlation between the increase of uricemia and triglyceride levels, triglyceride and cholesterol levels, BMI and triglyceride levels conferming the tight bond among these metabolisms and the importance of obesity as a risk factor. Uricemia levels correlate with systolic and diastolic blood pressure.

[Epidemiology and physiopathology of urinary incontinence after radical prostatectomy]. / Epidemiologia e fisiopatologia dell'incontinenza urinaria post prostatectomia radicale (RRP).

Beginning in the 1980s, a series of anatomical discoveries were introduced to modify the classic retropubic radical prostatectomy proposed by Millin in 1942 in an effort to reduce intra and postoperative complications such as intraoperative bleeding and postoperative erectile dysfunction and incontinence. Urinary incontinence post retropubic "anatomical" radical prostatectomy remains a distressing problem for the patient and the physician rating from 6 to 20% even in the hands of experienced surgeons from high volume Academic Centers. The reason for the discrepancy in results is unclear and should be searched in surgical experience of the surgeon, volume of surgical activity of the Center, and selection of the patients undergoing the radical retropubic procedure. In the Literature we identified methodological factors which can bias the data on post radical retropubic prostatectomy such as 1) Consensus is lacking on definition of continence and/or incontinence following radical retropubic prostatectomy 2) Different surgical techniques are compared: sphincter damaging, versus repairing, versus preserving; bladder neck sparing versus non sparing; nerve sparing versus non sparing 3) Patients with preoperative urinary incontinence are included in the series and the preoperative continence status is not known. 4) Different timing in registration of incontinence. 5) Different methods in data collection. This latter seems to be the most important reason for discrepancy in the collection of the data. Self administered questionnaires oriented to evaluate incontinence analyzed by a third party seem to be the most powerful and objective tool for post prostatectomy incontinence rating. Post prostatectomy incontinence may be attributed to sphincter dysfunction as a result of surgical injury during prostatic surgery and/or to bladder dysfunction including detrusor instability and decreased compliance resulting in stress or urge or mixed stress/urge postoperative incontinence. In the Literature bladder dysfunction is considered to be responsible or jointly responsible for post RRP incontinence in a rate as high as 93%. More recently, a major role is considered to be played in post RRP incontinence pathophysiology by intrinsic sphincter insufficiency. Rarely bladder dysfunction is an isolated cause of incontinence. Moreover the symptom of stress incontinence accurately predicts the finding of intrinsic sphincter deficiency. The apical dissection and the preservation of the intrinsic sphincter remain the most complex parts of RRP and the keys to the maintenance of postoperative urinary continence.

Life habits and cardiovascular risk in a group of bank employees in Rome.

BACKGROUND: For the past thirty years, many countries, especially the USA, have been performing clinical and laboratory studies to establish the most prominent disease risk factors, in particular those involved in cardiovascular diseases. The main aim of these studies is to reduce disease related risks by intervening at an early age. METHODS: We studied 305 patients, 198 males and 107 females, all employees in Rome, mean age 40.8 years (+/- 8.22), enrolled from September 1988 to December 1989. We measured the main anthropometric parameters and performed otolaryngologic and ocular examination, a telecardiogram and an EKG; the following analyses were performed: hemochrome, ESR uric acid, azotemia, glycemia, AST, ALT, gamma GT, bilirubinemia, proteic electrophoresis, triglyceridemia, total cholesterolemia, HDL cholesterolemia, creatinine, urine examination, Pap-Test for women. Lifestyle habits that might be considered cardiovascular disease risk factors were considered and hygienic eating habits were suggested. Seven years later, in 1997, 100 of these patients were randomly selected (51 man and 49 women) and underwent the same clinical and laboratory tests as before. RESULTS: The results suggest a deep correlation between lifestyles and the increase of some cardiovascular risk factors. CONCLUSIONS: The authors believe that this study can be of some help in guiding future preventive medicine interventions that may be carried out on this population sample.

Increase in the prevalence of symptomatic upper urinary tract stones during the last ten years.

PURPOSE: In industrialized countries the prevalence of upper urinary tract stones has continually increased during the 20th century, but there are considerable differences between countries and also within the same country. To study whether there is still an increase in the frequency of renal stones, an investigation was undertaken to determine the prevalence of stone formers in a village near Milan, Italy, during two time periods, with an interval of 12 years. MATERIALS AND METHODS: Questionnaires were administered in 1986 and 1998 to all adult (age >25 years) occupants of two random samples of households in the village. Participants were asked whether they had experienced a kidney stone during their lifetime. RESULTS: The overall prevalence of stone formers among males was 6.8% in 1986 and 10.1% in 1998; that among females was 4.9% in 1986 and 5.8% in 1998. In all age classes, the respondents in the 1998 survey more frequently reported a history of stones than in 1986, but the prevalence of renal stones was significantly higher in 1998 than in 1986 only among males aged 31-40 and 51-60 years. The yearly incidence was estimated at 0.4%, with 0.6 and 0.18% in men and women, respectively. CONCLUSIONS: This marked increase in renal stones could be the result of environmental factors such as dietary habits and lifestyle, in particular the influence of an increased consumption of animal protein should be considered.

Contact laser treatment for benign prostatic hypertrophy.

Transurethral resection of the prostate (TURP) is still the standard treatment of benign prostatic hypertrophy (BPH) but the surgical lasers recently introduced seem to offer the patient a very low perioperative complication rate, a short learning curve, the reduced operating time and the health care system a very low cost/benefit ratio. We report our personal experience with contact vaporizing laser ablation of the prostate (CLAP) paying attention to efficacy, safety and costs. Between December 94 and March 97, 67 pts (mean age 62.8 +/- 9 years) underwent CLAP for BPH (mean prostate volume 40.4 +/- 17.1 cc). Five pts presented coagulation disorders, five were renal transplant recipients and one had chronic renal failure requiring peritoneal dialysis. All patients were preoperatively submitted to digital rectal examination, transrectal prostatic ultrasound, dosage of serum PSA, determination of the International Prostatic Symptom Score (IPSS), the post voiding residual urine and maximum flow rate. All these exams were repeated at 1, 3, 6, 12 and 24 months after CLAP. The bladder pressure at maximum flow (Pdet-Qmax) was preoperatively determined in 23 patients and repeated at the six months follow up. For CLAP we used an SLT neodynium-YAG laser or diode laser with maximum potency 60 W. For statistical analysis we used Student's t-test for paired data. The mean operating time was 47.9 +/- 12.5 min (range 18-75 min) and the laser energy averaged 17.707 +/- 11.239 J (range 3000-58,000 J). The mean catheter time after CLAP was 2.5 days and the mean hospital stay was 4.8 days. No intraoperative complications occurred. Two patients 48/72 h after surgery presented macrohematuria requiring laser revision, three patients presented an acute urinary retention post catheter removal and one patient had acute prostatis. At the follow up, the IPSS score, Q max, Pdet-Qmax and PVU showed a significant statistical difference respect to baseline values. The prostate volume at the 180-day follow up was not significantly different from baseline values (42.1 +/- 16.8 cc vs 40.4 +/- 17.1 cc). Contact laser ablation of the prostate has been demonstrated to be efficacious and comparable to TURP in relieving BPH obstruction however the higher costs exceeding the TURP ones by 13%, the longer operative times and the lower durability of laser disobstruction impede to replace TURP with the CLAP.

Ultrasound-fluoroscopy guided access to the intrarenal excretory system.

The access to the collecting system can be performed under fluoroscopy computerized tomography, ultrasonographic, mixed ultrasonographic and fluoroscopic guidance. In this paper the creation of a percutaneous transparenchymal ultrasound-fluoroscopy guided access to the intrarenal collecting system completely performed by urologist for different purposes is presented. In five years 297 patients underwent 330 percutaneous kidney accesses to perform derivative nephrostomies (217 pts), percutaneous nephrolithotomies (37 pts), antegrade ureteral manoeuvres (34 pts), antegrade endopyelotomies (7 pts), transitional cell carcinoma of the upper tract resection (2 pts). 11 patients out of these had a percutaneous kidney access in a transplanted kidney. The percutaneous access was successful in 98% of the attemps. A posterior calyx of the lower group (74%), of the medium group (25%) or of the upper group (1%) was accessed. In 73 accesses the mean target calyx diameter was 12.8 mm (range 5-45 mm), the mean operative time 5.4 minutes and the mean fluoroscopy time 5.1 seconds. In 84.5% of the patients the access was performed under local anesthesia when a dilation of the tract was not required. Gross haematuria was observed in 3.9% of the accesses and an arterial lesion treated by embolization in 0.9% of the accesses. Blood transfusion was required in 0.3% of the patients. The ultrasound-fluoroscopy guided access is at least as precise as the fluoroscopy guided one moreover it makes the procedure less invasive and it makes more precise the surgical planning.

[The intracystic concentration of MCA in the fluid from large breast cysts]. / Concentrazione intracistica dell'MCA nel fluido di grosse cisti della mammella.

75 patients with breast gross cystic disease and no cancer have been included in the study. For each patients serous and intracystic concentrations of MCA have been measured. The aim of the study is to assess whether if a relation between intracystic concentration of the marker and resistance and capability of cellular reproduction exists (confirmed by the release of the cyst). The analysis of intracystic values shows that synthesis of MCA is an intrinsic peculiarity of cytologic kind. It is apparently independent from inflammatory or hemorrhagic contemporary processes.

Evaluation of urinary level of NMP22 as a diagnostic marker for stage pTa-pT1 bladder cancer: comparison with urinary cytology and BTA test.

BACKGROUND: In the present study we compared the clinical value of two new specific tests for transitional cell carcinoma, urinary nuclear matrix protein (NMP22) levels and bladder tumor antigen (BTA) test, with that of urinary cytology in the follow-up of patients with superficial bladder cancer. MATERIALS AND METHODS: Hundred and five bladder cancer patients were recruited: 30 stage pTa and 45 stage pT1 (group A), and 30 with a history of bladder cancer but no recurrence at the time of the study (group B). Urine samples were collected before any instrumental manipulation of the genitourinary tract. All patients were negative for urinary tract infections at conventional urine analysis. RESULTS: NMP22 at a cutoff value of 6 U/ml showed a sensitivity of 83.3% in pTa cases and 97.7% in pT1 cases, with a false-positive rate of 23.3%. The BTA test was positive in 26.6% of patients with cancer stage pTa and in 66.6% of pT1 stage, with 30% false-positives in the non-neoplastic group. Urinary cytology, performed on three consecutive samples, was positive in 20% of patients with cancer stage pTa and in 64.4% of pT1 stage and did not show any false-positive cases. Stratifying the neoplastic patients according to lesion grade, NMP22 (at a cutoff value of 6 U/ml) was positive in 86.2% of G1, 97.2% of G2 and 90% of G3. BTA was positive in 37.9, 52.7 and 70% of G1, G2 and G3, respectively, while urinary cytology was positive in 37.9, 44.4 and 80%.

[Production of PSA by breast adenocarcinoma cells: preliminary results]. / Produzione del PSA da parte di cellule di adenocarcinoma della mammella: risultati preliminari.

PSA has been measured out with highly sensitive method both in liquid of mammary cysts and in cytosol of neoplastic cells. Our data point out that dysplastic, metaplastic and anaplastic breast epithelial cells produce PSA. Such production is, probably, related to expression of hormonal receptors.

Microsatellite alterations in uterine leiomyomas.

Recent studies have shown that microsatellites instability (MI) has a leading role in the development of different types of cancer: a high rate of di-tri or tetranucleotide repeats have been found in familial polyposis and in sporadic colorectal, gastric, breast and endometrial carcinomas. In the present study, we selected the DNA of 23 histological samples from patients with uterine leimyomas, aged between 24 and 65 years. The negative portion was divided from the pathological portion in the same sample of each patient. Each sample was analyzed for 7 microsatellites (D25123, Mfd39, 635. 636. Mfd67, D11S905, SCZD1 and DM) through double amplification with the PCR using external and internal primer couples. Seven of 23 samples analyzed on the denaturant gel of acrylamide (30.4%) were positive for microsatellite alterations. The recurrence of these alterations, which appear in our study, suggest their involvement in benign transformation of smooth muscle cells.

[Immunoradiometric assay of Ca 125 in breast cystic fluid]. / Dosaggio immunoradiometrico del Ca 125 nel liquido di grosse cisti della mammella.

Ca 125 was assayed in serum and in breast cyst fluid of 78 patients with GCD. Levels of the marker in cyst fluid are generally < 30 U/ml. More significative results were found in relation to cysts relapse. In apocrine cysts relapse levels were higher than 270 U/ml, in serum cysts not relapsed levels were between 31-270 U/ml. Ca 125 could have a significative role in cell differentiation and its control.

Renal stone fragments following shock wave lithotripsy.

PURPOSE: We describe a select group of asymptomatic patients with fragments and dust 3 months after extracorporeal treatment, who were followed to evaluate the long-term outcome and therapeutic implications. MATERIALS AND METHODS: A total of 129 patients with dust and residual fragments (less than 4 mm.) at 3 months was re-examined at 12 months, and 95 were also evaluated at 24 months. Followup examinations consisted of radiographic studies, renal ultrasonography and urine culture. Dust and residual fragments were sought, and patients were defined as free or as having persistent lithiasis or stone regrowth. At 24 months recurrences in the patients stone-free at 12 months also were considered. RESULTS: At the 12-month followup 60 patients (46.5%) were stone-free and 56 (43.5%) still had dust or residual fragments. The localization of the stones or fragments at 3 months and their sizes did not have a significant influence on the stone-free rate but regrowth was greater in patients with stones larger than 10 mm. (11 of 40 patients, 27.5% versus 2 of 89, 2.2%, p = 0.001). The probability of eliminating residual lithiasis at 12 months was significantly greater in patients with dust than in those with residual fragments (42 of 79 patients, 58% versus 18 of 50, 36%, p = 0.026). Regrowth of residual lithiasis was observed in 13 patients (10%). CONCLUSIONS: Based on our results, we do not believe that patients with fragments require systematic re-treatment in the short term but they may be followed long term and re-treated if symptoms persist or stones recur.

[Levels of Cathepsin D in breast cyst fluid]. / Dosaggio della Catepsina-D nel fluido di macrocisti della mammella.

Cathepsin-D was assayed in serum and in breast cyst fluid of 60 non neoplastic patients with GCD. The results are independent from cytological type or possible cyst relapse. Although the study confirms the high levels of Cat-D in breast cyst fluid no predictive value has been demonstrated. Its expression may be related to systemic endocrine factors.

Effect of preseasonal enzyme potentiated desensitisation (EPD) on plasma-IL-6 and IL-10 of grass pollen-sensitive asthmatic children.

EPD is a method of preventive immunotherapy which employs b-glucuronidase as a biological response modifier. Plasma IL-6 and IL-10 were measured before a single injection of EPD, 24 hours later and 15 days after in a group of 17 children suffering from grass pollen asthma. 17 normal untreated children were used as controls. Although the study was conducted before the grass pollen season when the allergic children were free of symptoms, their plasma IL-6 and IL-10 were significantly elevated before the injection of EPD. 24 hours after treatment the plasma IL-10 had increased significantly and there was also a slight rise in IL-6. 15 days after treatment IL-6 had fallen to normal but IL-10 was still elevated. These findings suggest antigen-specific and non-specific mechanisms by which EPD may produce clinical improvement.

[Conservative treatment of renal cell carcinoma: framework, incidence and classification]. / La terapia conservativa nel carcinoma renale: inquadramento, incidenza e classificazione.

Recent interest in nephron sparing surgery for renal cell carcinoma has been stimulated by advances in diagnostic imaging, following an increasing number of incidentally discovered low stage renal cell carcinoma and good long term survival in patients undergoing this form of treatment. Tosaka et al reported a 5-years survival of 94.7% in patients with incidental renal cell carcinoma compared with 60.9% in diagnosed because symptomatic. Along with a diagnosis of carcinoma more and more premature, a whole string of little lesions is present, not easily identifiable by the recent diagnostic imaging. Tosaka and others examined renal lesions going by the ultrasonography as a check-up or as a first frame in patients suffering from microscopic hematuria; they proved that neoplastic lesions represent 5.4% of all the masses identifiable by diagnostic imaging. The frequent discovery of limited carcinoma, the difficulty in the diagnostic attribution and demonstration of the good survival of patients who were treated by a nephron sparing surgery, added to the one of patients undergone to radical nephrectomy, caused an interest in nephron-sparing surgery for incidental renal carcinoma also for patients with normal controlateral kidney and not very extended tumors, usually in peripheral sites. At the moment record of cases concerning nephron sparing surgery is quite limited, any way it shows a survival equal to 90% with only two local recurrences, reported only in one experience and caused by an incomplete resection or by multicentric neoplastic lesions.

Variation in nocturnal urinary excretion of melatonin in a group of patients older than 55 years suffering from urogenital tract disorders.

Melatonin (MLT) is directly or indirectly related to cell growth (both of normal and neoplastic cells), to the immune system stimulation and to the endocrine system modulation. This controlled study was carried out to evaluate urinary excretion of MLT in patients suffering from urogenital tract disorders. Eighty-one patients affected by urogenital disorders were divided in two groups (neoplastic and non-neoplastic) and urinary excretion of MLT was evaluated. Mean diurnal (from 8 a.m. to p.m.) urinary excretion of MLT was 4.97 + 6.08 pg/12 h in non-oncologic patients and 4.82 + 6.21 pg/12 h in oncologic patients (p = 0.50). Mean nocturnal (from 8 p.m. at 8 a.m.) urinary excretion of MLT was 11.97 + 9.34 pg/12 h in non-oncologic patients while in oncologic patients it was 7.86 + 8.95 pg/12 h. Statistically significant variation in nocturnal urinary excretion of melatonin was observed in oncologic patients (p = 0.022) versus non oncologic patients.

[Level of immunosuppressive acidic protein in the fluid of breast cysts]. / Dosaggio della proteina acida immunosoppressiva nel liquido di cisti mammarie.

IAP marker was detected by radio-immunodiffusion in breast gross cyst fluid and in serum. No correlation was found between this antigen and cyst' cytological type, serum concentrations and acute phlogosis. In most cysts IAP was not valuable; on the other hand, high levels of glycoprotein were found only in the subgroup on relapsed class of apocrine cysts.

[Orthotopic ileal neobladder: urodynamic and metabolic aspects. Our experience]. / Neovescica ileale ortotopica: aspetti urodinamici e metabolici. Nostra esperienza.

We subjected to a functional and metabolic evaluation (urodynamic examination + cystography) 10 patients underwent to radical cystectomy with a ileal orthotopic reservoir (VIP) for bladder cancer. At the moment patients have a minimum 3-years follow-up and they are out of disease. The medium capacity of the reservoir is about 447 ml, with a low pressure flow, a medium pressure of ureteral closing of 62.5 cm of H2O. At the cystography neither ureteral reflux nor post miction residuum have been proved. All the patients are continent, with the exception of one patient suffering from episodes of nocturnal enuresis. The metabolic evaluation hasn't proved substantial changes except the presence of hypocitraturia in the only patient in metabolic acidosis. In conclusion the ileal orthotopic reservoir showed a good long-term functionality without considerable complication of metabolism.

[pT1G3 bladder carcinoma: our experience]. / Carcinoma vescicale pT1G3: nostra esperienza.

Approximately 6 to 23% of the patients with transitional cell carcinoma confined to the superficial mucosa of the bladder suffer for a pT1G3 tumor. Between 1984 and 1994, 12 patients were treated for high grade stage T1 tumores. Trans-urethral resection of the bladder cancer was performed in 8 patients, supported in two cases by immunotherapy with B.C.G. and in one case by endovesical chemotherapy. Radical cystectomy was carried out in 4 patients. Our results are similar to what reported by other Authors, but we didn't have any progression in all 8 patients treated with conservative therapy.

[Radical perineal and retropubic prostatectomy: comparison of technics]. / Prostatectomia radicale perineale e retropubica: tecniche a confronto.

Today we may consider radical perineal prostatectomy as an example of mild invasive surgery compared with the retropubic. Technique is found less traumatic account of the precision of the approach, the accuracy of hemostasis and urethral bladder suture and the speed of postoperative handling. The only disadvantage related with the impossibility of transperineal pathological lymph node staging can today be satisfactory overcome after the advent of laparoscopic lymph node methods which permits safe non invasive preoperative hystological examination. The authors show the technique of laparoscopic and surgical therapy, concluding that perineal prostatectomy is a better approach toward retropubic radical prostatectomy, if combined with preoperative laparoscopic pelvic lymphadenectomy.
