Comparison of the corneal biomechanical properties,optic nerve head topographic parameters,and retinal nerve fiber layer thickness measurements in diabetic and non-diabetic primary open-angle glaucoma

The purpose of this study is to investigate the corneal biomechanical properties, optic nerve head (ONH) topographic parameters, and retinal nerve fiber layer (RNFL) thickness changes in primary open-angle glaucoma (POAG) patients with and without diabetes, as well as to evaluate the effect of the metabolic control of diabetes on corneal biomechanical properties, ONH topography, and RNFL thickness. A total of 101 eyes of 101 POAG patients (60 with diabetes and 41 without diabetes) were recruited in this prospective study. Corneal hysteresis and corneal resistance factor (CRF) were both measured using the ocular response analyzer. Optic disk parameters were evaluated using the Heidelberg Retina Tomograph-III. RNFL thickness was measured by using Spectralis HRA + OCT. CRF, mean rim area, and rim volume were found to be significantly higher in the diabetic group when compared with non-diabetic group (p = 0.01 for CRF, p = 0.04 for rim area and p = 0.02 for rim volume). ANCOVA analysis showed statistically insignificant effects of age, gender, MD, and PSD values over rim area and rim volume (p > 0.05). CRF was not significantly correlated with HbA1c levels (p > 0.05). Cup area (CA), cup volume (CV), and cup shape measure (CSM) were weakly correlated with HbA1c levels (r = 0.35 and p = 0.006 for CA; r = 0.32 and p = 0.01 for CV; r = 0.32 and p = 0.01 for CSM). The difference in mean RNFL thickness values between the groups was found to be insignificant (p > 0.05). The results of this study raise doubts whether or not diabetes does in fact shield POAG patients from glaucomatous optic nerve damage from various perspectives.     

Renal duplex Doppler ultrasonography as a predictor of preclinical diabetic nephropathy in children.

PURPOSE: To perform Doppler US in patients with insulin-dependent diabetes mellitus (IDDM) as a predictive method in diabetic nephropathy (DN). MATERIAL AND METHODS: Twenty-five patients with type I diabetes mellitus underwent renal Doppler US examination. Children were divided into three age groups: group I, 3-7 years; group II, 8-10 years; and group III, 11-18 years. The age-matched control group consisted of 56 healthy children who underwent renal Doppler US only. RESULTS: The mean values of the resistive index (RI) were, respectively, 0.64+/-0.03, 0.59+/-0.04, 0.59+/-0.02 in age groups I, II, and III for healthy children and 0.68+/-0.03, 0.62+/-0.04, 0.59+/-0.04 in age groups I, II, and III of the diabetic patients. There were no significant differences between the diabetic and healthy subjects. The mean RI value was not different in the patients with glomerular hyperfiltration compared to patients with normal filtration rate. Additionally, there were no significant differences between the mean RI value in patients with or without microalbuminuria. CONCLUSION: Renal Doppler US is not useful for prediction or for early diagnosis of DN.

Comparison of the effects of various anticancer agents on intestinal anastomosis after intraperitoneal administration

In this study, the effects of intraperitoneal 5-fluorouracil (5-FU), cisplatinum (Cis), adriamycin (Adr), and methotrexate (MTX) administration on rat intestinal anastomosis were compared. Cis and MTX led to significant weight loss in the first 5 days compared with the control group. Within 14 days all rats except the MTX group nearly reached their preoperative weight. No remarkable weight loss or systemic toxicity was observed among the 5-FU and Adr groups. The anastomosis bursting pressure (ABP) at 1 week was significantly lower than that of the control group (P<0.01 andP<0.005, respectively). On day 14 the anastomosis bursting pressure in the Cis group was similar to that of the control group but was significantly lower in the MTX group (P<0.002). Histopathologically, MTX avoided the development of a mucosal layer at the anastomosis site and led to ulcer formation in some of the rats. The ABPs at 7 and 14 days were similar to those in the control group. Neither of the agents had any significant mechanical or histopathologic adverse effects on anastomosis. According to the results of our study, MTX impaired the healing of the anastomosis, and we thus conclude that the intraperitoneal administration of this agent is not safe. On the other hand, Cis showed a detrimental effect on the anastomosis, particularly in the early phase, but this effect disappeared in the late phase. Cis thus should not be administered in the early postoperative phase. As a result, 5-FU and Adr were found to be the safest agents as they did not delay wound healing and did not reduce the anastomotic strength.     

The tanycytic ependymoma of the lateral ventricle: case report.

The tanycytic ependymoma is an extremely rare, primitive neuroectodermal tumor, arising from the ependymoglial cells or tanycytes. Such cells are generally seen in the primitive nervous system instead of the mature ependymal cells. The tanycytic ependymoma described in this report was found in a 42-year-old man. Histological analysis strongly suggested that this tumor originated from a primitive progenitor cell, the ependymoglia or the tanycyte in the lateral ventricle.     

吸烟对成年男子红细胞免疫及其调节功能影响的实验研究

[目的]探讨吸烟对红细胞免疫及其调节功能的影响。[方法]将208名健康成年男子分成两组：吸烟组（152人）和对照组（56人）,分别对其红细胞受体花环率（RBC－C3bRR)、红细胞免疫复合物花环率（RBC－ICR）、红细胞免疫增强因子（EF）及抑制因子（IF）进行测定。[结果]吸烟组的RBC－C3bRR、EF水平显著低于非吸烟对照组（P均＜0．01）,而RBC－ICR、IF水平则显著高于非吸烟对照组（P均＜0．01）;相关分析表明RBC－C3bRR、EF水平与吸烟量及吸烟时间呈负相关,而RBC-ICF、IF水平则与吸烟量及吸烟时间呈正相关。[结论]吸烟可引起继发性免凤功能低下及降低红细胞免疫调节能力。
