Background: Alteration of innate and acquired immunity can play a role in the mechanism involved in the development of dementia. Epidemiologic studies indicate that the use of non-steroidal anti-inflammatory drugs can delay the onset or slow progression of Alzheimer disease.

Objectives: To determine whether the use of NSAIDs[1] is associated with natural killer activity alteration in AD[2] and multi-infarct vascular dementia patients, as compared with non-demented elderly and healthy young people.

Methods: In this prospective open study four groups of subjects (AD, VD[3], non-demented elderly, and healthy young people) were treated with an NSAID drug (rofecoxib 12.5 mg/day or ibuprofen 400 mg twice daily) for 7 days. Natural killer cell cytotoxicity was measured after flow cytometry analysis before and after treatment.

Results: Of the 49 subjects studied, 15 had a diagnosis of AD (3 men, 12 women; mean age 83.5 ± 8.1 years), 15 had a diagnosis of multi-infarct VD (7 men, 8 women; mean age 75.5 ± 8.4), 13 were non-demented elderly (1 man, 12 women; mean age 80.2 ± 7.2), and 6 were healthy young volunteers (3 men, 3 women; mean age 36.8 ± 4.4). While all examined subjects showed decreased NK[4] cell cytotoxicity after treatment, this decrease was most prominent and statistically significant in elderly patients suffering from vascular dementia –  from an average of 30.5 ± 11.8% before treatment to 22.5 ± 16% after treatment (P = 0.04). The decrease in NK cell cytotoxicity was only moderate and not statistically significant in all other elderly and young subjects. Young healthy volunteers exhibited a significantly higher total NK cytotoxicity before and after treatment compared to all age groups (P < 0.001).

Conclusion: These findings suggest that NSAIDs decrease NK activity in vascular dementia patients. Our findings also suggest that natural killer activity alteration cannot explain the ability of anti-inflammatory drugs to delay the onset or slow the progression of AD.

 Background: Restorative proctocolectomy eliminates the risk of colorectal cancer in patients with familial adenomatous polyposis. Complications and extra‑intestinal manifestations are inherent to the procedure.

Objectives: To evaluate operative procedures, complications, early and late results and long-term functional outcome in FAP[1] patients operated in our department.

Methods: The study group included all patients with FAP who were operated between 1988 and 2003. Demographic data, length of follow‑up, complications, colorectal cancer, pouch function and extracolonic manifestations were recorded.

Results: Median age at surgery was 33 years (range 13–61 years). The final operative breakdown was: 48 proctocolectomies, 41 ileal pouch-anal anastomoses, 2 Kock’s pouch, 5 permanent ileostomies, and 2 colectomies with ileorectal anastomosis. There was no perioperative mortality. Early and late complications occurred in 20 and 9 patients, respectively. Twelve patients required re‑operation. Colorectal carcinoma was diagnosed in eight patients, three of whom were in an advanced stage. The mean follow‑up was 74 months (range 3–288 months). Four patients were lost to follow‑up. Extracolonic manifestations developed in 38 patients, including desmoid tumors (in 12), duodenal adenomas (in 9), pouch adenomas (in 5), and rectal stump adenomas (in 3). Two patients died (4%) because of desmoid tumor and malignant fibrous histiocytoma. At last follow‑up, 37 IPAA[2] patients have (median) six bowel movements/24 hours and good fecal control.

Conclusions: Restorative proctocolectomy can be performed with low mortality, acceptable morbidity, and good functional results. Patients should be closely followed after surgery for development of other manifestations of the syndrome. Relatives of the affected patients should be referred to a specialist multidisciplinary clinic.

 Background: Uveitis is an acute or chronic inflammatory process of the uvea caused by a number of etiologies. In many patients the etiology is unknown.

Objective: To investigate the effect of the Dead Sea environment (climatotherapy) on the signs, symptoms and clinical course of chronic uveitis.

Methods: Fifty-five patients with chronic uveitis were examined at the beginning and end of a 3–4 week stay at the Dead Sea region and on repeat visits to the region. Study data included demographic information, medical history, etiology, diagnosis, medication, and a complete ophthalmic examination.

Results: Statistically significant improvements were seen between the two examinations within each visit in four parameters (negative values indicate improvement): a) visual acuity for near and far: Jaeger (‑1.18 ± 0.28, P < 0.0001) and best corrected visual acuity (‑0.08 ± 0.02, P < 0.0001); b) anterior chamber flare (-0.18 ± 0.06, P < 0.01); c) anterior chamber cells (-0.16 ± 0.05), P < 0.001); and d) vitreous cells (-0.15 ± 0.09, P < 0.05). There was a significant mean improvement during visits to the Dead Sea area and a slight dissipation of the effect during the intervals between visits. Sixty-four percent of the patients reported that they required less medication and had fewer and milder attacks of uveitis following the visits.

Conclusions: The results of this study provide evidence of short- and possibly long-term improvement in the signs and symptoms of uveitis following exposure to the Dead Sea environment.

Background: Along with the increased life expectancy in cystic fibrosis and the remarkable progress in its management and therapy, issues of female fertility and pregnancy are frequently raised. These include infertility, severity of lung disease, pancreatic insufficiency, poor nutritional status, glucose intolerance and diabetes, drug safety, and long-term maternal and neonatal outcome.

Objective: To describe the experience of our CF[1] center in the management of CF pregnant woman from 1977 to 2004.

Methods: We analyzed 27 years of records (1977–2004) of the national CF registry of all CF women who wished to conceive and became pregnant.

Results: Eight CF women (mean age 24 ± 4.5 years) who wished to conceive had 11 pregnancies and delivered 12 neonates. The pregestational results of forced expiratory volume per 1 second varied significantly among patients (59 ± 23%), yet most (10/11) stayed stable throughout the pregnancy course. Maternal deterioration in CF condition occurred in only one mother, necessitating cesarean section. In 9 of the 11 pregnancies the women were pancreatic-insufficient. Of the 11 pregnancies, 2 CF women had diabetes mellitus and 3 developed gestational diabetes. One pregnancy occurred in a mother with a transplanted lung. Of the 12 neonates, 3 were preterm and one was born with esophageal atresia. No miscarriages, terminations or neonatal mortalities occurred. Although most of the CF mothers had FEV1[2] below 55% before pregnancy, the maternal and neonatal outcome was favorable and lung function tests generally remained stable.

Conclusions: We conclude that pregnancy in CF is feasible with a positive maternal and neonatal outcome. Early participation of the CF physician in the wish of the CF woman to reproduce is required. The integration of an intensive multidisciplinary approach during pregnancy, which includes close follow-up of maternal and fetal condition by the various specialists, should ensure an optimal outcome.

 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.

Endometriosis is a chronic disease characterized by ectopic deposits of endometrial glands and stroma located outside the uterus. Women with symptomatic endometriosis may experience premenstrual bleeding or staining, pain and other physical sensations, as well as other symptoms dependent upon the stage and location of the endometrial implants. We discuss the particular implications of these symptoms for women who observe the part of Jewish law known as hilkhot niddah. The laws of niddah, also known as taharat hamishpahah (family purity), dictate the timing of the physical relationship between a married couple. These laws proscribe any physical contact between the couple during the time that the wife has the status of niddah. This status is obtained by any uterine bleeding that is not caused by injury. Menstruation is the most common cause of the niddah status, but niddah and menstruation are not synonymous. Since, to the best of our knowledge, there is no written discussion of the specific implications of endometriosis for this population, we discuss the relevant halakhic and medical literature and hope that such analysis will facilitate efforts to assist the observant couple in gaining regular niddah-free segments of time

Due to the increase in longevity today, advanced illness in the elderly exists together with severe disability and often dementia that generally become less responsive to known treatment. This leads to repeated admissions to an internal ward in a general hospital, which results not only in a lack of treatment continuity but also in inappropriate management resulting in over- or under-treatment. Towards the end of their lives, the treatment problems of non-oncologic elderly patients with advanced diseases stem from a number of factors: multiple pathology, difficulty in predicting irreversibility, staff reluctance to discontinue active specific treatment and resort to palliative care only, and the lack of a framework to ensure continuity of treatment in the community or hospital. These advanced systemic illnesses are characterized by fluctuating exacerbations and remissions, making it very difficult to assess irreversibility. This article proposes the establishment of advance centralized care planning, based on community care, the geriatric hospital and, in particular, a geriatric support unit within the skilled nursing department, catering holistically for the ongoing needs of the patient and his/her family and supplying a backup to the community care.

Background: Continuous positive airway pressure is the treatment of choice for patients with obstructive sleep apnea syndrome.

Objective: To determine the factors influencing treatment initiation with a CPAP[1] device in a healthcare system in which co-payment is required.

Methods: A total of 400 adult patients with OSAS[2] who required CPAP therapy completed questionnaires at three different stages of the diagnostic and therapeutic process: CPAP titration study (stage 1), patient adaptation trial (stage 2), and purchase of a CPAP device (stage 3). Logistic regression was used to analyze the variables influencing CPAP use at the different stages of the diagnostic and therapeutic processes.

Results: Only 32% of the patients who underwent CPAP titration study purchased a CPAP device. The number of subjects who purchased a CPAP device increased gradually as monthly income increased, 28% vs. 62% in the “very low” and “very high” income levels respectively. Reporting for the titration increased in patients with excessive daytime sleepiness and an Epworth Sleepiness Scale score above 9 (odds ratio = 1.9, P = 0.015). Higher socioeconomic status increased reporting to stage 2 (OR[3] = 1.23, P = 0.03) and CPAP purchase (stage 3, OR = 1.35, P = 0.002). Excessive daytime sleepiness increased reporting to stage 2 (OR = 2.28, P = 0.006). Respiratory disturbance index above 35 increased CPAP purchasing (OR = 2.01, P = 0.022). Support from the bed partner, referring physician and sleep laboratory team increased CPAP purchasing.

Conclusions: A supportive environment for a patient with OSAS requiring CPAP is crucial to increase initiation of CPAP treatment. Minimizing cost sharing for the CPAP device will reduce inequality and may increase CPAP treatment initiation.

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.

Various events occurring during pregnancy might influence the normal neurogenesis of fetus brain, including exposure to the influenza virus. Several studies have attempted to find a relationship between exposure to influenza virus and the onset of schizophrenic behavior in childhood or adulthood, however results remain contradictory. In this review we describe several animal and human studies that show or do not show a relationship between exposure to the influenza virus during pregnancy and the subsequent development of schizophrenia.
