[Acute renal ischemia--unusual cause of lumbar pain].

Acute renal artery occlusion is rarely found in daily clinical practice. Its rarity and inespecific clinical presentation are responsible for late diagnosis or diagnostic errors, with symptoms frequently being erroneously attributed to other more common entities. There is no consensus in what concerns therapeutic options. Multiple treatment modalities are described in the available literature. Some defend anticoagulant therapy and support measures only while others recommend other more invasive alternatives reaching even open surgery. The authors present two additional case reports of acute embolic renal ischemia. A thorough literature review is also presented comprehending etiological, clinic, diagnostic and therapeutic aspects.

[Bulbourethral sling. The experience of our service].

OBJECTIVES: The authors present the clinic results obtained with the bulbourethral sling application with pubic bone anchorage (Invance) in patients with stress urinary incontinence. MATERIAL AND METHODS: From July to December 2003, 10 slings were implanted in men between the 60's and the 83 years old (average 72.6 years), whose incontinence appeared after prostatic surgery (retro pubic radical prostatectomy, perineal radical prostatectomy, radical cystoprostatectomy with Camey II neobladder, transurethral resection, transvesical prostate adenomectomy). RESULTS: After 9 months follow-up (3 to 7 months), 8 patients (80%) are continent (without need of using any pad) and 2 (20%) show minimum leakage with effort (need of 1 to 2 daily pads). All are satisfied with the surgery result. Two patients referred perineal pain, which was solved with Paracetamol. There was no case of perineal haematoma, infection, rejection or urethral erosion. CONCLUSION: The bulbourethral sling with bone anchorage is a rather invasive procedure, of easy technical execution, with high continence rates and associated to low morbidity. Although the presented results been an incentive to the technique prolongation, it would be necessary a higher tracking: and higher global experience in order that this sling affirm and transform itself in an alternative to the artificial sphincter in selected cases.

The vinification of partially dried grapes: a comparative fermentation study of Saccharomyces cerevisiae strains under high sugar stress.

AIMS: The study of the fermentation performance of Saccharomyces cerevisiae strains under high sugar stress during the vinification of partially dried grapes. METHODS AND RESULTS: Microvinification of partially dried grape must with sugar concentration of 35 degrees Brix was performed using four commercial strains to carry out alcoholic fermentation. A traditional red vinification without nutrients addition was applied. Yeasts displayed different efficiency to convert sugar in ethanol and varied in glycerol yield. Sugar consumption and ethanol level were attested at 80-87% and 143.5-158.0 g l(-1) respectively. High correlation between sugar and assimilable nitrogen consumption rate was observed. Statistical treatment of data by principal component analysis highlighted the different behaviours that strains exhibited in regard to the production of higher alcohols and other compounds important to wine quality. CONCLUSIONS: Saccharomyces cerevisiae strains displayed appreciable capability to overcome osmotic stress and to yield ethanol fermenting high sugar concentration grape must in winemaking condition. SIGNIFICANCE AND IMPACT OF THE STUDY: The results provided insights on the strain contribution to wine quality subordinate to stress condition. This investigation is of applicative interest for winemaking and processing industry that use high sugar concentration musts.

[Inverted papillomas--cases at our service and review of the literature].

Inverted papillomas are rare tumours representing about 2.2% of all urothelial tumours (benign or malignant). Inverted papillomas are predominantly seen in the bladder but these tumours have also been described in other locations, all over the urinary tract. The authors report six additional cases of such tumours describing the individual characteristics of each case, presenting symptoms, treatment employed and follow up available. A review of the literature relative to aetiology, clinical signs and symptoms, diagnostic criteria, treatment options and outcome has also been carried out.

New abutment for a screw-retained, implant-supported crown.

The 1-piece, implant-supported abutment and crown, colloquially described as the UCLA abutment, commonly is used to fabricate single, screw-retained crowns. This abutment was designed to allow attachment of the crown directly to the implant and requires a waxing and casting procedure by a laboratory technician. A new prefabricated abutment has been developed that uses a similar approach but does not require the waxing and casting process. The PDQ abutment is made from a metal-ceramic alloy that is custom contoured by grinding to support a porcelain veneer. Porcelain then is fired to the contoured abutment to develop the 1-piece artificial crown. This article describes the use of the PDQ abutment.

Prognostic factors in childhood intracranial ependymomas: the role of age and tumor location.

Despite several clinical reports on intracranial ependymomas in children, the factors which affect prognosis, and the possibility that certain combinations of factors might limit survival, are still a matter of debate. Between 1976 and 1996 we operated on 35 children with intracranial ependymomas. Postoperative irradiation was given to 27 patients, with associated chemotherapy in 6 cases. Mean follow-up was 62 months. In 12 patients a 5-year follow-up was possible. In October 1996, 18 patients (51.4%) were still alive, the longest disease-free follow-up being 20 years, and the shortest 8 months. We analyzed the prognostic relevance of eight factors. For each factor, different subgroups were distinguished and compared as follows: age at diagnosis (<4 vs. >/=4 years), sex, tumor location (supratentorial vs. infratentorial), tumor size (<4 vs. 4-7 vs. >7 cm), surgical removal (total vs. subtotal), histology (low-grade vs. anaplastic), morphology (solid vs. cystic), adjuvant therapies (treatment vs. no treatment). Two-way contingency tables were made to identify associations between variables. The only significant association was between age and tumor location (p = 0.022): in children under 4, tumors were almost invariably located in the posterior fossa (9 out of 10 cases) with a clear preference for the lateral recess (8 cases). Other correlations were not significant. Kaplan-Meier survival curves were compared to assess the prognostic relevance of each factor. Survival was significantly lower for children under 4, for those with posterior fossa tumors, and for patients with residual tumor (p < 0.05). A multivariate analysis compared variables which significantly affected survival, revealing that age is the most important factor affecting prognosis (p < 0.05), while tumor location and surgical removal do not add any significance to the effect of age on survival. We conclude that age has the strongest prognostic relevance in childhood intracranial ependymomas, while the effect of tumor location on survival may be related to the high incidence of lateral recess ependymomas in younger children.

[Vesico-scrotal hernia. Report of a clinical case].

Incidental discovery of vesical hernias during herniorrhaphy is quite common. In such cases, patients are usually asymptomatic since the hernia portion is small and easily repairable. On the other hand, vesical solid protrusion to the scrotum is quite unusual, and is generally found associated to obstructive urinary symptoms. Management involves basically the correction of any associated obstructive conditions, correction of the vesical hernia and herniorrhaphy.

[Solitary fibrous tumor. Two additional cases with urologic implications].

Solitary fibrous tumour is a well defined pathological entity originally described as a tumour of the pleura, but the occurrence of this neoplasm has increasingly been described at other sites. At present the development of these tumours is recognized as possible in virtually all anatomical sites. The rarity of this type of pathology has not allowed up to the present time clarification of the histogenesis, clinical behaviour, treatment and prognosis of these tumours. Differential diagnosis becomes important, especially in extra-thoracic sites so as not to mistake them for much more aggressive mesenquimal tumours. Two additional cases of this neoplasm are presented, one of them responsible for obstructive uropathy, accidentally found in a patient suffering renal trauma. The second tumour was located in the spermatic cord. A review of the theme is presented based on the available literature.

[Imperforate syringocele of the Cowper's glands laparoscopic treatment].

OBJECTIVES: The authors present a clinical report of an imperforate syringocele diagnosed on a male patient and treated by laparoscopic surgery. MATERIAL AND METHODS: A forty-four year old patient attends the emergency room with acute urinary retention. With a former history of mild obstructive voiding symptoms, he presented, at rectal examination, a bump on the left rectal wall. This patient also underwent urethrocistoscopy, sonography and retrograde urethrography. To establish the diagnose, Computerized Tomography (CT) scan and MRI were used. RESULTS: The syringocele marsupialization by laparoscopic surgery, allowed the resolution of the clinical problem, with a good outcome. The patient was discharged 48 hours after surgery, with no need of a vesical catheter. A six month follow-up showed no recurrence. CONCLUSIONS: The syringocele is a rare deformity which usually is asymptomatic. Of acquired or congenital etiology, it can be classified in four different morphological types: simple, perforate, imperforate and ruptured. The most frequent treatment is the marsupialization of the syringocele by endoscopic surgery, leaving a broad opening of the cavity to the urethra. Some authors recommend an open surgery excision, specially in the presence of an abscess. The laparoscopic approach becomes a minimally invasive alternative with good therapeutically outcome. In the incidentally discovered asymptomatic patients, an expectant approach is the correct approach.

[Hematuria].

Patients referred for hematuria work-up are frequently seen in the urologic practice. The initial evaluation does not require the participation of a urologist or nephrologist, due to the false sense of security in the evaluation of an asymptomatic and persistent hematuria. In fact, an adequate history and physical followed by urinalysis and radiologic tests, such as IVP and ultrasonography, must be made in the initial evaluation to exclude any serious urologic/nephrologic disease.
