Background: Preoperative radiotherapy is standard treatment for rectal cancer and is often combined with 5-fluorouracil-based chemotherapy. UFT, a new oral 5FU[1] derivative, given daily during a course of radiotherapy mimics the effect of continuous-infusion 5FU.

Objectives: To determine the maximum tolerated dose of oral UFT and leucovorin with preoperative pelvic irradiation for rectal cancer, and assess tumor response.

Methods: In this phase 1 trial, 16 patients aged 42–79 years with tumors within 12 cm of the anal verge received radiotherapy, 45 Gy over 5 weeks, an escalating dose of oral UFT, and a fixed dose of 30 mg/day leucovorin. UFT and leucovorin were given for 28 consecutive days concomitant with the first 4 weeks of radiotherapy. Surgery was scheduled for 4–6 weeks after completion of radiotherapy. The surgical procedure was determined by the surgeon at the time of surgery.

Results: No grade III toxicity was seen at 200 mg/m²/day UFT. Of eight patients who received 240 mg/m²/day UFT, one developed grade IV diarrhea; of four patients who received 270 mg/m²/day UFT, one was hospitalized with grade IV diarrhea and leukopenic fever and died during hospitalization. Of the 15 evaluable patients, 9 had pathologic tumor down-staging including 4 patients with complete response. Only one patient required a colostomy.
Conclusions: The MTD[2] of UFT together with leucovorin and preoperative radiotherapy for rectal cancer is 240 mg/m². The major toxicity was diarrhea. Down-staging was noted in 60% of patients, allowing sphincter-preserving surgery even in patients with low tumors.

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: 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: Prenatal care in Israel is established as a universal service, but the degree of compliance with care recommendations may vary with the healthcare provider or the characteristics of the population.

Objectives: To study referral to and compliance with the performance of ultrasound, alpha-fetoprotein and amniocentesis and the factors associated with them in a national sample. 

Methods: The sampling frame consisted of women who gave birth during March 2000. The sample included 1,100 Israeli Jewish and Arab women who resided in localities with over 50,000 and 20,000 inhabitants respectively. They were interviewed by phone 3 months after delivery. 

Results: In both population groups 30% reported having seven or more ultrasounds during pregnancy. The performance of fetal body scans was relatively low. Factors associated with non-performance among Jewish women were: lower education, religiousness, and attending Mother and Child Health services as compared to all other services. Seventy-seven percent of Jewish women and 84% of Arab women reported that they had been referred for alpha-protein tests. For women aged 35 and over, 55% of Jewish women were referred and 63% complied, whereas 39% of Arab women were referred but none complied.

Conclusions: Ultrasound is almost universally performed among Jewish and Arab women; however fetal body scans, alpha-fetoprotein and amniocentesis (for women over the age of 35) are not. The reasons for the lower coverage may be due to under-referral and/or lack of compliance of the women, perhaps due to sociocultural barriers. In both population groups considerable out-of-pocket money is paid for the tests.

Background: Eyes scheduled for posterior segment surgery may have cataract, which obscures the visualization of the retina. Surgery may be carried out either by a two-step procedure: i.e., removal of the cataract followed later by posterior segment surgery; or it may be done in a single session: i.e., combined surgery of both the anterior and posterior segments.

Objective: To evaluate the outcomes of combined surgery by phacoemulsification and vitrectomy.

Methods: We retrospectively reviewed the records of 42 patients with coexisting cataract and vitreoretinal disease who underwent combined surgery by phacoemulsification and pars plana vitrectomy at one session.

Results: Indications for surgery were vitreous hemorrhage in 71.4%, retinal detachment in 11.9%, macular hole in 11.9%, and epiretinal membrane in 4.8%. There were no significant intraoperative complications.The main early postsurgical complications were fibrinous formation in 11.9%, elevated intraocular pressure in 23.8%, and recurrent vitreous hemorrhage in 9.5%. There were a few late complications related to phacoemulsification: posterior synechia in 9.5%, posterior capsular opacification in 7.1%, and dislocating intraocular lens in 4.8%. Recurrent retinal detachment occurred in five eyes and rubeoisis iridis in one. Visual acuity was improved in 85.8%, stable in 7.1% and worse in 7.1%.

Conclusions: Phacoemulsification performed at the time of posterior segment surgery enables good visualization during the vitrectomy, facilitates surgery, and is associated with only minor complications. In cases with cataract and vitreoretinal diseases, combined surgery by phacoemulsification and vitrectomy in one session may be considered.
