Background: Adhesive capsulitis, also termed “frozen shoulder,” is controversial by definition and diagnostic criteria that are not sufficiently understood. The clinical course of this condition is considered as self-limiting and is divided into three clinical phases. Several treatment methods for adhesive capsulitis have been reported in the literature, none of which has proven superior to others.

Objectives: To evaluate the long-term follow-up of patients with idiopathic adhesive capsulitis who were treated conservatively.

Methods: We conducted a long-term follow-up (range 5.5–16 years, mean 9.2 years) of 54 patients suffering from idiopathic adhesive capsulitis. All patients were treated with physical therapy and non-steroidal anti-inflammatory drugs.

Results: An increased statistically significant improvement (P < 0.00001) was found between the first and last visits to the polyclinic in all measured movement directions: elevation and external and internal rotation.

Conclusions: Conservative treatment (physical therapy and NSAIDs[1]) is a good long-term treatment regimen for idiopathic adhesive capsulitis.

Background: Pulmonary disease is the most frequent cause of morbidity and mortality in cystc fibrosis patients. New techniques such as non-invasive positive pressure ventilation have resulted in prolongation of life expectancy in CF[1] patients with end-stage lung disease.

Objectives: To determine the role of NIPPV[2] in CF patients awaiting lung transplantation.

Methods: Between 1996 and 2001 nine CF patients (5 females) with end-stage lung disease were treated with bi-level positive airway pressure ventilation in the "spontaneous" mode.

Results: The patients' mean age at initiation of BiPAP[3] was 15 years (range 13–40 years) and the mean duration of BiPAP usage was 8 months (range 3–16 months). Four patients underwent successful lung transplantation, three patients died while awaiting transplantation, and the remaining two are still on NIPPV while waiting for transplantation. Patients' body mass index increased significantly (P < 0.05) during BiPAP therapy (from 16.1 to 17.2 kg/m²). Blood pH, p_aCO₂, and bicarbonate improved significantly (from 7.31 to 7.38, 90.8 to 67.2 mmHg, and 48.9 to 40.3 mEq/L, respectively). Pulmonary function tests were not affected by BiPAP usage. The patients experienced a significant alleviation in morning headaches and improvement in quality of sleep (P < 0.003). There were no major complications during BiPAP usage.

Conclusions: We demonstrated that long-term NIPPV can stabilize and improve physiologic parameters such as ventilation, arterial blood gases and body mass index, as well as subjective symptoms such as sleep pattern, daily activity level, and morning headaches in CF patients with end-stage lung disease. Further prospectively controlled studies are needed to evaluate the potential of BiPAP therapy and its influence on morbidity and mortality in the post-lung transplantation period.

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].

Background: Hyperthermia combined with radiation therapy was shown to be more effective in local recurrent breast cancer than radiotherapy alone, but it use is limited due to technical difficulties, stringent reimbursement policies and because it is time consuming.

Objectives: To report our experience with a simple and convenient XRT+HT[1] delivery system.

Methods: XRT was delivered through either electron or photon beams (total dose 30–40 Gy in previously irradiated fields or 50–70 Gy in non-irradiated fields). Hyperthermia was delivered by a dedicated HT device operating at 915 MHz. The heating session lasted 45 minutes. The maximal tumor surface temperature was set at 45°C and modified according to patient comfort. No intratumoral (invasive) thermometry was used. At least two HT sessions were scheduled to each HT field during the entire XRT treatment period. Tumor response was evaluated every 3 months after completion of treatment. The overall survival was measured from XRT+HT initiation until the last follow‑up.

Results: Fifteen women underwent 114 HT treatments delivered through 28 HT fields. Twenty-four HT fields (15 patients) were previously irradiated. There was complete infield response in 10 fields (6 patients), partial response in 8 fields (4 patients), no response or progressive disease in 4 fields (3 patients), and no parameters in 6 fields (5 patients). Eighteen (64%) fields had complete or partial response. Seven patients had outfield recurrence despite wide XRT+HT fields. Ulceration was the only major side effect (three patients, three fields).

Conclusions: The combined HT+XRT delivery system, with no invasive thermometry, is a simple and effective method for treating local recurrent breast cancer.

Background: The role of prostatic fossa radiation as salvage therapy in the setting of a rising prostate-specific antigen following radical prostatectomy is not well defined.

Objectives: To study the efficacy and safety of pelvic and prostatic fossa radiation therapy following radical prostatectomy for adenocarcinoma.

Methods: A retrospective review of 1,050 patient charts treated at the Sheba Medical Center for prostate cancer between 1990 and 2002 identified 48 patients who received post-prostatectomy pelvic and prostatic fossa radiotherapy for biochemical failure. Two patients were classified as T-1, T2A-9, T2B-19, T3A-7 and T3B-11. Gleason score was 2–4 in 9 patients, 5–6 in 22 patients, 7 in 10 patients and 8–10 in 7 patients. Positive surgical margins were noted in 28 patients (58%) of whom 18 had single and 10 had multiple positive margins. Radiation was delivered with 6 mV photons using a four-field box to the pelvis followed by two lateral arcs to the prostatic fossa.

Results: At a median follow-up of 34.3 months (25th, 75th) (14.7, 51,3) since radiation therapy, 32 patients (66%) are free of disease or biochemical failure. Exploratory analysis revealed that a pre-radiation PSA[1] less than 2 ng/ml was associated with a failure rate of 24% compared with 66% in patients with a pre-radiation PSA greater than 2 ng/ml (chi-square P < 0.006).

Conclusions: For patients with biochemical failure following radical prostatectomy early salvage radiation therapy is an effective and safe treatment option.

Background: Hyperhomocysteinemia is a well-recognized risk factor for accelerated atherosclerosis in hemodialysis patients.

Objectives: To examine the effects of two doses of vitamins B6 and B12 and folic acid on homocysteine levels in hemodialysis patients and assess the functional impact of the methylenetetrahydrofolate reductase genotype on the response to treatment.

Methods: In a randomized prospective study, we assessed the effects of folic acid and two doses of B-vitamins in 50 hemodialysis patients with hyperhomocysteinemia. Patients were divided into two groups: 26 patients (group A) who received 25 mg of vitamin B₆ daily and one monthly injection of 200 µg vitamin B12, and 24 patients (group B) who received 100 mg of vitamin B6 daily and one monthly injection of 1,000 µg vitamin B12. In addition, both groups received 15 mg folic acid daily. Patients were evaluated for homocysteine levels as well as for coagulation and a thorough lipid profile. Baseline Hcy[1] levels were determined after at least 4 weeks washout from all folic acid and B-vitamins that were given. MFTHR[2] alleles were analyzed, as were activated protein C resistance, von Willebrand factor and lupus anticoagulant.

Results: Basal plasma Hcy levels were significantly elevated in hemodialysis patients compared with normal subjects (33.8 ± 4.3 vs. 4.5 to 14.0 mmol/L). Following treatment, Hcy levels were significantly reduced to 21.2 ± 1.6 in group A and 18.6 ± 1.4 mmol/L in group B (P < 0.01). There was no difference in Hcy reduction following the administration of either high or low dosage of vitamins B6 and B12 utilized in the present study. There was no correlation between Hcy levels or thrombophilia and high incidence of thrombotic episodes in hemodialysis patients. Genotypic evaluation of MTHFR revealed that the presence of homozygous thermolabile MTHFR (n = 5) was associated with higher Hcy levels and better response to treatment (Hcy levels decreased by 58%, from 46.2 ± 14.6 to 19.48 ± 4.1 mmol/L following treatment). In patients with heterozygous thermolabile MTHFR (n = 25), Hcy levels decreased by 34%, from 31.2 ± 3.7 to 18.1 ± 1.1 mmol/L following treatment. The efficacy of high and low doses of B-vitamins on the reduction of homocysteine levels was comparable.

Conclusions: Treatment with B-vitamins in combination with folic acid significantly decreased homocysteine levels in hemodialysis patients, independently of the tested doses. In addition, mutations in MTHFR were associated with elevated plasma levels of Hcy. Neither vascular access nor.

Background: Arterial involvement in Behçet's syndrome is rare. Aneurysms are common among the arterial lesions, affecting various arteries but mostly the abdominal aorta. Surgical interposition graft insertion is the treatment of choice for large aneurysms. However, vasculitis in these patients is the reason for the notorious surgical complications that result in up to 50% false aneurysms in anastomotic sites. Recently, endovascular repair for abdominal aortic aneurysms has been established.

Objectives: To learn more about vascular Behçet and, specifically, to compare the results of surgical treatment and endovascular repair of AAA[1] in patients with Behçet's syndrome.

Methods: We retrieved the medical records of all 53 patients with Behçet disease admitted to Rambam Medical Center during the years 1985 and 2001 and analysed the results and follow-up of open surgery versus endovascular repair of AAA in patients with known Behçet's syndrome.

Results: Of the 53 patients with Behçet's disease 18 had vascular manifestations (34%). AAAs were encountered in 8 patients (15%) and 5 were treated. Open surgery (group 1), under general anesthesia, lasted less than 3 hours with an average aortic clamping time of 34 minutes (range 26–41 min) after which the patients were transferred to the intensive care unit for 24–48 hours. Endovascular treatment (group 2), although lasting about the same time without the need for intensive care, necessitated contrast media and fluoroscopy. The length of hospital stay was considerably shorter for patients after endovascular repair compared to open surgery (3 days vs. 6 days). Combined mortality and morbidity was higher in patients who underwent open surgery compared to endovascular repair (one death, one major amputation and three anastomotic pseudoaneurysms compared to one temporary contrast-induced nephropathy).

Conclusions: Vasculo-Behçet patients with AAA are better candidates for endovascular treatment than atherosclerotic patients. Combined morbidity (especially anastomotic pseudoaneurysms) and mortality of Behçet patients after endovascular repair is considerably lower than after open surgery.
