Abstract
Behcet disease (BD) is a systemic inflammatory disease of the unknown etiology. There is however, some evidence to suggest that immunological abnormalities are important in its pathogenesis, furthermore several T-cell abnormalities which may be quite relevant to autoimmune origin of the disease have been described. We report here our study of T-cell subsets, B and NK cells in 68 patients with BD in comparison to 30 normal controls, by monoclonal antibodies against CD3 (pan T-cell), CD4 (Helper) CD8 (Suppressor/cytotoxic), CD22 (B-cell) and CD16 (NK-cell) markers. The results show the increase (P=0.008) of T (CD3), T (CD4) (P<0.000001) and decrease of T (CD8) (P<0.000001) and reduction in ratio of CD4/CD8 cells (P<0.000001), but any alteration in B and NK cells number were not seen. In patients with BD 69.8% negative PPD test and above results suggests that the cellular immunity in these patients is anergic, which may be an important etiological factor.

Abstract

Introduction: The bone mass density (BMD) may vary in different countries due to different genetic and environmental factors. This study was performed to determine the BMD of the normal population in Iran.

Methods and Materials: Subjects were selected randomly from different works and social classes in Tehran (from the lowest to the highest). For each decade and sexes, 20 normal subjects were selected (140 men and 140 women). BMD was measured with a Hologic 1000 plus machine by dual energy x-ray absorptiometry (DEXA) method for the lumber spine (L1, L2, L3, L4, L1-L4) and the femoral neck (neck, trochanter, intertrochanter, ward, total). Data were treated by polynomial approximation (3 rd degree). The obtained curves were compared with the standard Hologic curves for Caucasians.

Results: In female the peak bone mass (PBM) was 1.019 g/cm² for the lumbar spine and 0.832 for the femoral neck. In male the peak bone mass (PBM) was 0.987 g/cm² for the lumbar spine and 0.907 for the femoral neck. The BMD of both lumbar spine and femoral neck were lower than the Hologic standards. For the lumbar spine the mean difference was 6.5 percent (2 to 21 percent, CI=1) for women and 13.8 percent (2 to 36 percent, CI=1.45) for men. In femoral neck the mean difference was 5.4 percent (2 to 16 percent, CI=0.96) for women and 4.6 percent (1 to 14 percent, CI=0.96) for men.

Conclusion: The BMD of the lumbar spine and the femoral neck was lower in Iranian compared to the Hologic standards for Caucasians. This was seen in all age groups and in both sexes. It was less pronounced for the PBM in spine was lower in men than woman. The lower BMD of the spine in men was also seen in a cohort of patients with different diseases (inflammatory and non-inflammatory).

Abstract

Background: Surgical staging is the standard treatment of ovarian cancer. Pelvic and para-aortic lymphadenectomy is the important part of the surgery. The aim of this study was to evaluate the effect of para aortic lymph node dissection in early stage of patients with ovarian cancer.

Methods: This descriptive cross-sectional cohort study was performed on all stage I of ovarian cancer patients admitted in department of gynecology oncology of Ghaem Hospital, Mashhad University of Medical Sciences in November 2012 to March 2014. Every patient with clinical early stage of ovarian cancer candidate to surgical treatment selected. All cases underwent surgical staging surgery with concurrent systematic pelvic and para-aortic lymphadenectomy. In laparotomy after identification of left and right iliac artery, all lymph nodes have been properly exposed and dissected as a part of a staging laparotomy. The dissection was continued up to the nodal tissues surrounding the aorta, and inferior vena cava, until inferior mesenteric artery lymphadenectomy level. The procedure performed only by gynecologist oncologist. In addition, we assessed other parameters such as operation time, estimated blood loss, associated mortality and morbidity and vascular injuries. Finally, the effect of para aortic lymph node dissection in early stage of ovarian cancer evaluated.

Results: Among a total of 57 ovarian cancer patients, 27 of them apparent stage I disease cases were selected. Surgical staging surgery with concurrent systematic pelvic and para-aortic lymphadenectomy was carried for all of them. Positive para-aortic lymph node was found only in one case. The average number removed para-aortic lymph nodes in the pelvis was 9 and in para aortic was 7, respectively. In addition, 20 minutes increase in total length of operation time was observed duo to para-aortic lymphadenectomy. Also the rate increase in intra-abdominal hemorrhage rate was estimated 60 ml.

Conclusion: Lymph node dissection will produce a significant benefit in accurate and complete surgical staging. Staging surgery in addition to systematic pelvic and para aortic lymph adenoctomy in early stage ovarian cancer is preferred in gynecologic oncology centers.
