Although the airway granulomata in Wegener's granulomatosis were stressed initially by Friedrich Wegener himself, in the last few decades systemic lesions mainly caused by acute vasculitis have received the most attention. However, recently, the implication of granulomatous manifestations in WG[1] has raised much interest. The present data suggest that an aberrant Th1-type response might play a role in the initiation of WG, clinico-pathologically characterized by granulomatous inflammation rather than vasculitis. Disease progression to generalized WG with the predominance of vasculitic manifestations is associated with a “switch” or further complexity of the collective T cell response with the appearance of another subset of Th2-type cells and a less prominent Th1-type cytokine production in the granulomatous lesions of the upper respiratory tract. However, the clinical significance of the granulomatous inflammation is not yet completely understood. Further research will also have to focus on the role of the granulomata during relapsing disease. We review present knowledge of granulomatous inflammation in WG. Morphologic aspects, the scale of cytokine alterations as well as the variety of clinical manifestations are discussed.

 Background: Stents offer a simple and effective drainage method for the upper urinary tract. However, ureteral stents are associated with frequent side effects, including irritative voiding symptoms and hematuria.

Objectives: To determine the side effects associated with ureteral stents and their impact on sexual function and quality of life.

Methods: Symptom questionnaires were administered to 135 consecutive patients with unilateral ureteral stents. The questionnaire addressed irritative voiding symptoms, flank pain, hematuria, fever, loss of labor days, anxiety, sleep impairment, decreased libido, erectile dysfunction, dyspareunia, painful ejaculation, and a subjective overall impact on quality of life. The items were graded from 1 (minimal or no symptoms) to 5 (maximal symptoms). The patients were seen and questionnaires filled at 2 weekly intervals following stent insertion until stent extraction. Following removal of the stent, stent patency, impaction and migration rates were determined. Admissions to hospital and ancillary procedures to retreive stents were noted.

Results: The findings presented refer to questionnaire items scoring 3 or more. Dysuria, urinary frequency and urgency were reported by 40%, 50% and 55% of the patients, respectively. Flank pain, gross hematuria or fever was reported by 32%, 42% and 15% respectively. Among working patients, 45% lost at least 2 labor days during the first 14 days, and 32% were still absent from work by day 30. A total of 435 labor days were lost in the first month. Anxiety and sleep disturbance were reported by 24% and 20% respectively, and 45% of patients reported impairment in their quality of life. Decreased libido was reported by 45%, and sexual dysfunction by 42% of men and 86% of women. Stent removal necessitated ureteroscpoy in 14 patients (10.5%), due to upward migration in 11 (8.2%) and incrustration and impaction in 3. Spontaneous stent expulsion occurred in one patient. Forty-six (34%) stents were obstructed at the time of removal. Obstructed stents were associated with a longer mean dwell time as compared to the whole population, 75 versus 62 days respectively (P = 0.04).

Conclusions: Ureteral stents are associated with frequent side effects and significantly impact on patient quality of life. Our findings should be considered when deciding on ureteral stent insertion and dwell time.

 Background: The preferred conservative treatment for congenital idiopathic clubfoot deformity remains a controversial issue.


Objectives: To compare the outcomes of two groups of CICF[1] patients who underwent two different treatment protocols.

Methods: The study cohort included 72 infants treated in our hospital from August 1998 to December 2002. Group 1 comprised 40 infants (61 clubfeet) who were treated by a traditional method (a modification of the Kite and Lovell technique), and group 2 consisted of 32 infants (48 clubfeet) who were treated with the Ponseti technique. Both groups were similar in age, gender and severity of the deformity (Dimeglio scoring system)

Results: After an average follow-up of 54.9 months (range 44–68), 35 (57%) clubfeet in group 1 required surgical intervention and 27 (44%) clubfeet had a residual deformity at last follow-up. In the Ponseti group, 45 (94%) clubfeet were fully corrected at last follow-up (average 29.2 months, range 16–45) while 3 (6%) clubfeet had residual deformity and required surgery. Tendo-Achilles tenotomy was performed with no complications in 47 clubfeet (in group 2) at an average age of 2.4 months (range 2–4 months).

Conclusions: Even after a relatively short follow‑up period, our success rate with the Ponseti approach already appears to be significantly higher and to bear fewer complications than the traditional treatment, in agreement with the results published by other medical centers. We now endorse the Ponseti technique of conservative manipulative treatment for congenital idiopathic clubfoot in our department.

Highly active antiretroviral therapy has dramatically improved the quality of life and life expectancy of patients with human immunodeficiency virus. However, the prolonged use of HAART[1] leads to severe metabolic adverse events. Both HIV[2]infection and HAART can cause changes in lipid and glucose metabolism as well as elevation of blood pressure, promoting the development of atherosclerosis. Cardiovascular diseases have become a major cause of mortality among HIV-infected subjects who respond well to antiretroviral therapy. Nevertheless, a proper lifestyle and pharmacologic intervention can improve cardiovascular risk factors in the HIV-treated population and significantly reduce healthcare investments in the treatment of future cardiovascular complications in this population. In this review we summarize the current knowledge of CVD[3] prevention and treatment in HIV patients.

 Bleeding during retropubic radical prostatectomy arises from venous structures in the majority of cases. Since its introduction two decades ago, the nerve-sparing procedure with surgical control of the dorsal venous complex has led to a reduction in blood loss and blood transfusion rate. The reduction in blood loss is a result of better understanding of the prostatic blood vessel anatomy, extensive surgical experience over time, and reduction in transfusion triggers with an acceptance of lower postoperative hemoglobin values. Increased blood loss during RRP[1] is associated with poorer outcomes most probably due to surgical difficulties. But as for now, there are no decisive risk factors for clinically significant bleeding during RRP although newer technologies for hemostasis of the dorsal vein complex are being utilized.

Background: Heterotopic ossification is a common complication of hip surgery and musculoskeletal or brain traumas.

Objectives: To confirm by in vivo study that colchicine inhibits osteoblast cell proliferation with marked decrease in tissue mineralization.

Methods: Heterotopic ossification was induced in three groups of New Zealand white rabbits (females, 6 months old, weight 3–3.5 kg) by injecting 2 ml bone marrow drawn from the iliac crest into their right thigh muscle. To prevent heterotopic ossification, colchicine (0.25 mg/day) was administered orally for 4 weeks to two groups of adult rabbits: group A (preload group) – 1 week preceding bone marrow injection; group B – on day of injection; and group C – control group.

Results: After 4 weeks the rabbits were evaluated by radiographs and ultrasound for evidence of heterotopic ossification. At the end of the study histologic samples were taken from all the thighs. Imaging and histologic studies showed, with statistical significance, almost complete prevention of heterotopic ossification formation in group A (preload) and a marked decrease in group B, when compared with the controls in whom large new bone had formed at the injection site. These results indicated the inhibitory effects of colchicine on a bone-forming process in soft tissue such as heterotopic ossification.

Conclusions: The role of colchicine in preventing heterotopic ossification in other bone-forming conditions, such as hip arthroplasty or pelvic trauma, and after brain trauma, remains to be evaluated in a clinical setting.

Background: Bladder exstrophy is a severe congenital defect that requires a multidisciplinary treatment approach. Soft tissue repair may be successful during the first few days after birth but a combination of pelvic osteotomies and bladder reconstruction is necessary later in life. The combination of externally fixed anterior and posterior osteotomies has biomechanical advantages over previous techniques for achieving primary bladder closure.

Objectives: To describe our experience with a combined vertical and horizontal pelvic osteotomy approach for the repair of bladder exstrophy.

Methods: Four children underwent bladder exstrophy closure; the mean age at surgery was 19 months (range 9–33 months)... We stabilized the osteotomies with a small Synthes AO external fixator, 4.0 mm rod diameter.

Results: All four patients had successful bladder repair with no dehiscence; two of them achieved partial continence, and bladder neck reconstruction is planned for the other two. Three of the four patients sustained neurologic injury; two completely recovered, and the third continues to suffer from right drop foot. The average follow-up was 39 months (range 10–60 months).


Conclusions: Vertical and horizontal pelvic osteotomies stabilized by external fixator and bladder repair is an effective treatment for bladder exstrophy.

Melanoma is the leading cause of death from skin tumors worldwide, with an annual increase in incidence over the past decade. The molecular mechanisms involved in melanoma pathogenesis are beginning to be unraveled. While a family history of melanoma and exposure to ultraviolet irradiation have been known for years as risk factors in melanoma development, the precise genes involved in inherited predisposition were defined only in the past decade. Germline mutations in two genes that play a pivotal role in controlling cell cycle and division – CDKN2A and cyclin-dependent kinase 4 (CDK4) – have been detected in autosomal, dominant, high penetrance familial melanoma cases. In addition to these two highly penetrant genes, germline mutations and polymorphisms in a few low penetrance genes have been reported in familial melanoma cases: melanocortin-1 receptor, epidermal growth factor, glutathione s-transferase M1, cytochrome p450 debrisoquine hydroxylase locus (CYP2D6) and vitamin D receptor.

Background: Follow-up examinations in a rehabilitation center clinic after stroke are essential for coordinating post-acute services and monitoring patient progress. Of first-stroke patients discharged from our rehabilitation ward to the community 92% are invited for ambulatory check-up once every 6 months.

Objectives: To review patient complaints at follow-up and the recommendations issued by the attending physical medicine and rehabilitation specialist at the outpatient clinic.

Methods: We extracted relevant data from the records, and assessed the relationship between functional status on admission and discharge (measured by FIM[1]), length of stay, and number of complaints. Patients were divided according to the side of neurologic damage, etiology, whether the stroke was a first or recurrent event, and main clinical syndrome (neglect or aphasia).

Results: Patients' complaints included: decreased hand function (40%), general functional deterioration (20%), difficulty walking (11%), speech dysfunction (10%), various pains (especially in plegic shoulder) (8%), urine control (2%), sexual dysfunction (3%), swallowing difficulties (2%), and cognitive disturbances (2%). Patients received the following recommendations: physiotherapy (52.5%), occupational therapy (37.5%), speech therapy (12.5%), different bracing techniques (22.5%), pain clinic treatment (12.5%), changing medication prescriptions (7.5%), psychological treatment (10%), sexual rehabilitation (5%), vocational counseling (2.5%), counseling by social workers (2.5%), and recurrent neuropsychological diagnosis (2.5%). A reverse correlation was found between the number of complaints and FIM at admission (P = 0.0001) and discharge (P = 0.0003), and between LOS[2] and FIM at admission (P = 0.0001) and discharge (P = 0.004). A direct correlation was found between the number of complaints and LOS (P = 0.029). No relation was found between age, type of stroke, first and recurrent event, and clinical syndromes and patient complaints in the outpatient rehabilitation. Community rehabilitation services met 58% of all recommendations in 62% of patients, mainly physiotherapy and occupational therapy, with 34% of patients waiting for implementation of the recommendations and 4% not available for follow-up.

Conclusions: Follow-up examinations should be an integral part of post-stroke rehabilitation. Rehabilitation treatment in the community must be strengthened.

Background: Cystoscopy, the principal means of diagnosis and surveillance of bladder tumors, is invasive and associated with unpleasant side effects

Objectives: To determine the early complications of rigid cystoscopy and the impact on patients' quality of life and sexual performance.

Methods: One hundred consecutive patients undergoing diagnostic rigid cystoscopy filled in questionnaires including anxiety and pain levels (0–5 visual analogue scale), adverse events, short-form health survey, International Prostate Symptom Score, and functional sexual performance. Questionnaires were administered before, immediately after, and 1, 2 days, 2 and 4 weeks following cystoscopy.

Results: The pre-cystoscopy anxiety level was 2.01. The average pain during the examination was 1.41. SF-36[1] score was not affected by cystoscopy. The subjective impact on patients' quality of life was 0.51. The mean IPSS[2] increased following cystoscopy (6.75 vs. 5.43, P = 0.001) and returned to baseline 2 weeks later. A decline in libido was reported by 55.6% (25/45) and 50% (3/6) of the sexually active men and women, respectively. Cystoscopy was associated with a decreased Erectile Dysfunction Intensity Score, from 15.6 to 9.26 during the first 2 weeks (P = 0.04). The overall complication rate was 15% and included urethrorrhagia and dysuria. None of the patients had fever or urinary retention and none was hospitalized. The complication rate was higher in patients with benign prostatic hyperplasia (24% vs. 9.7%, P = 0.001).

Conclusions: Rigid cystoscopy is well tolerated by most patients and has only a minor impact on quality of life. However, cystoscopy transiently impairs sexual performance and libido. The early complications are mild and correlate with a diagnosis of BPH[3].
