A unique case of late complication of rectum mesh erosion after laparoscopic sacrocolpopexy.

Sacrocolpopexy, a surgical technique with a low morbidity rate, is a valid procedure for repairing vaginal vault prolapse. To our knowledge, only 1 case of rectum erosion after open sacrocolpopexy has been reported in the literature, and there is no record of any such incident after laparoscopic sacrocolpopexy. We report the first case of mesh erosion involving the rectum instead of the vagina assessed 8 years after laparoscopic sacrocolpopexy.

[Occurrence of ticks (Acari: Ixodidae) in public parks in Cuneo province (Piemonte, Italy)]. / Zecche (Acari: Ixodidae) nelle aree verdi urbane destinate ad attività ricreative: indagine in 17 comuni della provincia di Cuneo (Piemonte, Italia).

Mites Ixodidae (hard ticks) may represent an important public health problem even in urban green areas. In the present study, by doing weekly samples, the green areas (playgrounds, parks, picnic areas for dogs, etc.) of 17 municipalities in the province of Cuneo (Piedmont, Italy) have been inspected, for a total of about 18,710 m2 monitored. No sample was found positive for mites Ixodidae. From this study it can be concluded that the green areas surveyed do not pose a risk to the population, while probably the greatest risk of infestation for humans has to be found in domestic spaces and areas of woodland and forests.

Asymptomatic bacteriuria in candidates for active treatment of renal stones: results from an international multicentric study on more than 2600 patients.

The occurrence of asymptomatic bacteriuria concomitant to urolithiasis is an issue for patients undergoing renal stone treatment. Disposing of a preoperative urine culture is essential to reduce the risk of septic events. The endpoint of the study is to report which characteristics of candidates for renal stone treatment are frequently associated with positive urine culture. 2605 patients were retrospectively enrolled from 14 centers; inclusion criteria were age > 18 and presence of a single renal stone 1-2 cm in size. The variables collected included age, gender, previous renal surgery, comorbidities, skin-to-stone distance, stone size, location, density, presence of hydronephrosis. After a descriptive analysis, the association between continuous and categorical variables and the presence of positive urine culture was assessed using a logistic regression model. Overall, 240/2605 patients (9%) had preoperative bacteriuria. Positive urine culture was more frequent in females, patients with previous renal interventions, chronic kidney disease, congenital anomalies, larger stones, increased density. Multivariate analysis demonstrated that previous renal interventions (OR 2.6; 95% CI 1.9-3.4; p < 0.001), renal-related comorbidities (OR 1.31; 95% CI 1.19-1.4; p < 0.001), higher stone size (OR 1.06; 95% CI 1.02-1.1; p = 0.01) and density (OR 1.00; 95% CI 1.0-1.00; p = 0.02) were associated with bacteriuria; male gender and lower caliceal location were inversely related to it. Beyond expected risk factors, such as female gender, other parameters are seemingly favoring the presence of positive urine culture. The awareness of variables associated with bacteriuria allows to assess which individuals are at increased risk of presenting bacteriuria and reduce the rate of septic complications.

Adrenal extramedullary hematopoiesis: report on a pediatric case and update of the literature.

The authors report on a rare pediatric case of adrenal extramedullary hematopoiesis in a patient with beta-thalassemia disease. The lesion was clinically discovered as incidentaloma of the right adrenal gland and treated by surgery. Adrenal extramedullary hematopoiesis may clinically be detected as incidentaloma. Adrenal incidentalomas presenting with hematologic disorders, such as agnogenic myeloid aplasia and beta-thalassemia, need careful imaging as well as adrenal hormonal investigation in order to exclude malignancy and subclinical hypersecretory syndromes. Ultrasound or CT-FNA of the lesion are effective in finding out the disease.

Adult primary teratoma of the testis--report on 5 cases in clinical stage I disease.

OBJECTIVES: Testis pure teratoma accounts for 2.7% to 3% of all germ cell tumors in adult where it behaves as a malignant neoplasm. Pure teratoma of the testis presents in clinical stage I disease in 44% of the patients whose risk of having pathological stage II disease is 16.7% to 19.2%. Herein we report on 5 cases of adult pure teratoma of the testis presenting itself in clinical stage I disease. MATERIALS AND METHODS: From September 1976 to February 2000, 75 patients underwent orchidectomy for clinical stage I nonseminomatous germ cell cancer of the testis. Testis pure teratoma was detected in 5 patients (7%). Testis tumor markers were evaluated in all cases. Patients underwent imaging examination to detect the clinical stage of the disease. Treatment options after orchidectomy included retroperitoneal lymph node dissection (RPLND) in 4 patients and surveillance in 1. RESULTS: The average age of the patients was 31 years (range 24-45). The tumor was on the left sided in 3 cases (60%) and right in 2 (40%). Tumor average size was 3.2 cm (rang 1-6). Histopathology detected the following subtypes: mature teratoma in 3 cases (60%), immature teratoma in 1 (20%) and teratoma with malignant transformation in (20%). All patients were at clinical stage I disease. Germ cell cancer microscopic metastatic disease including embryonal carcinoma was detected in I dissected lymph node of 1/4 patients (25%). Average follow up was 166 months (range 93-249). All patients were alive and disease free and no relapses were detected during the follow up period. CONCLUSIONS: Primary pure teratoma of the testis does not respond to chemotherapy nor does it to radiation therapy. The disease treatment options after orchidectomy for patients with clinical stage I disease include RPLND or surveillance with their relative risks and benefits. RPLND is the chosen treatment because it is both staging and treating. A close a long term follow up is required since pure teratoma metastatic disease may clinically develop after more than 10 years.

Adrenal incidentalomas: surgical treatment in 28 patients and update of the literature.

INTRODUCTION: Adrenal masses discovered by imaging techniques for reasons unrelated to adrenal diseases are called adrenal incidentalomas (Al). The aim of this study was to find out the clinical outcome of 28 patients operated for incidentally discovered adrenal mass and to update the literature concerning this topic. PATIENTS AND METHODS: From September 1976 to December 1999 we operated on 28 patients for adrenal incidentaloma. Adrenal masses were unilateral in 25 cases and bilateral in 5. Average age was 57 years (range 10-73). Hormonal study was performed in all patients. All patients underwent adrenalectomy by the transabdominal subcostal approach. RESULTS: Histopathology assessed the adrenal masses as primary in 19 patients and secondary in 9. 24-hour urinary vanillylmandelic acid (VMA) excretion was elevated in 2 patients. Adrenal insufficiency was detected in 1 case. Average tumor diameter resulted 5.8 cm (range 2-17). Histopathologic features of primary adrenal masses included pheochromocytoma in 5 cases, cysts in 4, myelolipomas in 3. nodular hyperplasia in 2, tuberculous mass in 1, cortical adenoma in 1, extra-bone marrow hemopoiesis in 1, cortical carcinoma in 1 and neuroendocrine tumor of the adrenal medulla in 1. The 9 adrenal metastasis resulted by renal cell carcinoma in 7 patients, urothelial carcinoma of the upper urinary tract in I and primary renal lymphoma in 1. Average follow-up was 68 months (range 6-246). Patients alive were 18 (64%), deal 10 (36%). Of the 19 patients with primary adrenal tumors 16 (84%) were alive and disease free and 3 (16%) died (I for disease and 2 for reasons unrelated to the primary tumor). Of the 9 patients with adrenal metastasis 2 (22%) were alive (I disease free and I with progression of the disease) and 7 (78%) died for disease. Replacement therapy for adrenocortical hormones was given 5 patients. CONCLUSIONS: Management of Al need CT or MRI and hormonal investigation in order to detect malignancy and subclinical hypersecretory syndromes. Subclinical functional adrenal masses, single adrenal metastasis and primary nonhypersecretory adrenal tumors sized 4 cm are treated by surgery. A close morpho-functional follow-up is indicated for primary adrenal incidentalomas when nonhypersecretory and smaller than 4 cm.

[Exogenous risk factors for parenchymal carcinoma of the kidney]. / Fattori di rischio esogeni per il carcinoma parenchimale del rene.

In the last decades incidence rates for renal cell carcinoma have been constantly increasing, especially in western European and Scandinavian countries and North America. Several epidemiological studies observed an increased relative risk of this tumour linked with some exogenous and/or environmental factors. The following exposures have been more consistently associated with renal cell carcinoma: tobacco smoking; occupational exposures (asbestos, aromatic hydrocarbons, chemical solvents); dietetic factors such as high energy intake, consumption of fried meats and poultry, and reduced intake of fruit and vegetables; iatrogenic factors such as analgesics and amphetamines; common diseases like obesity and hypertension. An effective preventive strategy for renal cancer could be carried out reducing the exposure to such risk factors.

[Fournier's gangrene: report of 2 cases and review of the literature]. / Gangrena di Fournier: osservazione di due casi e revisione della letteratura.

Fournier's gangrene is an extensive fulminant infection of the genitals, perineum or the abdominal wall. Since the first description by Jean Alfred Fournier in 1883 about 700 cases have been reported in the literature. The main aetiological factors are: perianal, perirectal or periurethral infections, diabetes mellitus and chronic alcoholism. Many aerobic and anaerobic organisms may be involved. Mortality rates range from 30-50%. The dramatic course of Fournier's gangrene requires early recognition, surgical drainage, extensive surgical debridment, antimicrobial therapy, hyperbaric oxygen therapy, as well as intensive care treatment in order to prevent irreversible endotoxic shock. We report two cases of Fournier's gangrene. In both cases symptoms were fever, pain and extensive cutaneous necrosis in the scroto-perineal region.

[Leydig cell tumor of the testis]. / Il tumore del testicolo a cellule di Leydig.

It represents a rare and mostly unilateral pathology with benign istological patterns. However, since the biological behaviour of the tumor is not foreseable from the istological characteristics, the follow-up must be prolonged. The treatment of this cancer is orchidofuniculectomy, sometimes associated, in selected cases, with retroperitoneal lymphadenectomy. In presence of tumor of small dimensions, above all if bilateral ones, it may be indicated a conservative treatment. Authors report six cases of Leydig cell tumors of the testis observed in sixteen years. All patients had orchidofuniculectomy by inguinal approach. In only one case has been associated retroperitoneal lymphadenectomy for the suspect of lymphatic metastasis. Follow-up of 3 months to 15 years is available for all patients: no one has died for the tumor and all are without signs of disease.

[Our experience in the treatment of retroperitoneal fibrosis]. / Nostra esperienza nel trattamento della fibrosi retroperitoneale.

To discuss retroperitoneal fibrosis (RPF) etiopathogenesis and to report on our experience in the treatment of the disease. From 1977 to 1998 26 RPF patients, 15 idiopathic (I group) and 11 secondary (II group), entered our clinic. Vascular risk factors of the I group were cigarette smoking (73.3%) and arterial hypertension (46.6%). Etiologic factors of the II group were aorta abdominal aneurysm (four cases), radiation therapy for female genital tract cancer (four case), aorto-bifemoral bypass for aorta aneurysm (two cases), retroperitoneal non-Hodgkin lymphoma (one case). Treatment performed for idiopathic disease was medical in eight cases (alone in two, with endourologic measures in six) using corticosteroids in five and tamoxifen in three; only endourological in three and surgical in four (nephrectomy in two patients, ureterolysis and ureteroneocystostomy in one, pyeloureterolysis in one) with perioperative corticosteroid treatment in three cases. Treatments performed in patients with secondary disease were endourologic in five surgical in three (ureteroureterostomy, ureteroneocystostomy, pyeloureterolysis and pyeloreduction), medical with corticosteroids in two; one patient affected by perianeurysmatic fibrosis did not require any treatment because of disease's spontaneous recovery. Medical treatment induced symptom remission and plaque reduction in all patients. Surgery determined complete recovery in all patients except for one in whom the disease relapsed with controlateral urinary tract involvement. Medical RPF treatment for idiopathic or secondary disease is effective in the first stage. Disease management with tamoxifen is easy to perform, safe and effective. In the steady state of RPF the best results are obtained by surgery and perioperative glucocorticoid therapy reduced significantly fibrosis' relapse.

[Histopathologic risk factors in patients with non-seminomatous germ tumors of the testis in clinical stage 1. Retrospective study of 75 patients]. / Fattori istopatologici di rischio in pazienti con tumore germinale non seminomatoso del testicolo in stadio clinico 1. Uno studio retrospettivo su 75 pazienti.

OBJECTIVES: This retrospective study was performed to evaluate histopathologic prognostic risk factors in 75 patients on clinical stage 1 nonseminomatous germ cell cancer of the testis (NSGCTT). METHODS: From September 1976 to February 2000 we operated on 75 patients for NSGCTT on clinical stage 1 disease. Average age was 29.5 years (range 16-71). After orchiectomy, therapeutic options included retroperitoneal lymph node dissection (RLND) for 44 patients (58.6%), surveillance for 26 (34.6%) and neoadjuvant chemotherapy for 5 (6.6%). Testis primary tumor samples were assessed for studying prognostic risk factors that included vascular and/or lymphatic invasion (IV/IL+), percentage of embryonal carcinoma (%EC) and absence of yolk sac tumor (YS-). RESULTS: All patients were alive and disease-free. The average age follow-up was 84.5 months (range 1-254). Relapses occurred in 11 (14.6%) patients after an average follow-up of 9.09 months (range 3-24). Prognostic risk factors were detected as follows: IV/IL+ in 17 cases (22.7%), (50-80%) EC in 23 (30.6%), CE% > 80 in 23 (30.6%), YS- in 55 (72%). In 8 (10.6%) patients there was not any prognostic risk factor. Disease relapse related to prognostic risk factors was detected as follows: 18.1% for VI/LI, 90.9% for EC% > 50 (27.2% for 50-80% EC and 63.6% for CE% > 80) and 90.9% for YS-. Relapsing rates between patients with EC% > 80 and 50-80% EC resulted statistically significant (p = 0.02, odds ratio = 12.25). Relapsing rates between patients on surveillance and those who underwent RLND was next to be significant (p = 0.05, odds ratio 3.68). CONCLUSIONS: EC% > 80 is a prognostic risk factor for disease relapse in patients with clinical stage 1 NSGCT who are selected in a high risk group requiring RPLND or neoadjuvant chemotherapy as therapeutical option.

[Surgical repair of congenital penile curvature]. / La correzione chirugica degli incurvamenti congeniti del pene.

Congenital penile curvature is not such a rare pathology and it is responsible for important aesthetic and functional problems. This malformation, can render intercourse difficult and painful, but it can be cured with a simple surgical procedure that almost always guarantees excellent results. In this work we report on the treatment of 48 patients (aged 16-34) with congenital penile curvature with a follow-up of 6 months to 10 years. The aetiology is also briefly analysed. A discussion follows on the diagnostic criteria for better interpretation of the main characteristics of this problem in relation to its functional appearance. A comparison of different surgical techniques is also shown, focusing over the procedure we perform: plissettage of the tunica albuginea. This technique is performed through a penile skin incision opposite to the maximal curvature of the organ, exposure of the tunica albuginea and the positioning of one or more series of stitches. The overall results show that 44 out of 48 patients were fully satisfied both from the aesthetic and functional points of view, while 4 were partly satisfied from the aesthetic point of view alone.

[Clinical and instrumental evaluation of erectile impotence: a proposal of a diagnostic protocol]. / Valutazione clinico-strumentale dell'impotenza erettile: proposta di protocollo diagnostico.

There has been increasing interest in recent years in patients complaining of erectile dysfunction. This has prompted research and the development of diagnostic procedures aimed at allowing increasingly rapid characterization of the type of impotence involved (psychogenic or organic) and thus the most effective treatment. In this preliminary study, we present our study methodology in patients with erectile dysfunction, emphasising in particular the diagnostic procedures best suited to revealing the presence of an organic cause in the pathogenesis of impotence.

[The complications of lumbotomies]. / Le complicazioni delle lombotomie.

After having described the surgical anatomy of the lumbar region, with particular regard to the relationships with pleura and peritoneum, as well as to the course of the nervous structures of the region (12th intercostal, ileohypogastric and ileoinguinal), the authors describe the possible complications related with the surgical approaches to the lumbar region. Pathogenesis of post-operatory pains and parietal hypotonies is especially evaluated; these complications may be caused by section, ligature or compression of one or more nervous trunks. The authors conclude that the respect of the anatomic structures located in the lumbar region represents the best way in order to prevent most complications related to lumbotomies.
