血液采集和单采期间不良反应的发生率:一项单中心研究

通常认为异体血液采集的献血者发生不良反应和损伤的发生率低,但自体献血者不良反应发生率的数据则自相矛盾,单采不良反应的发生率和预测献血者反应的因素还知之甚少。 本文分析了作者输血中心1998年1月到2001年6月记录的血液和单采献血者的所有不良反应。作者对发生不良反应与未报告任何不良反应的献血者之间的人口统计学和身体特征进行比较,以便确定不良反应预测因素的存在。     

Algorithm for the treatment of type 2 diabetes: a position statement of Brazilian Diabetes Society

The Brazilian Diabetes Society is starting an innovative project of quantitative assessment of medical arguments of and implementing a new way of elaborating SBD Position Statements. The final aim of this particular project is to propose a new Brazilian algorithm for the treatment of type 2 diabetes, based on the opinions of endocrinologists surveyed from a poll conducted on the Brazilian Diabetes Society website regarding the latest algorithm proposed by American Diabetes Association /European Association for the Study of Diabetes, published in January 2009.An additional source used, as a basis for the new algorithm, was to assess the acceptability of controversial arguments published in international literature, through a panel of renowned Brazilian specialists. Thirty controversial arguments in diabetes have been selected with their respective references, where each argument was assessed and scored according to its acceptability level and personal conviction of each member of the evaluation panel.This methodology was adapted using a similar approach to the one adopted in the recent position statement by the American College of Cardiology on coronary revascularization, of which not only cardiologists took part, but also specialists of other related areas.     

Combined lensectomy,vitrectomy, and primary intraocular lens implantation in patients with traumatic eye injury

Purpose To analyse the postoperative anatomic and functional outcomes in addition to complications after combined lensectomy, vitrectomy, and primary intraocular lens (IOL) implantation in patients with traumatic eye injury. Methods Retrospective review of patients with traumatic cataract and posterior segment injury who underwent combined lensectomy, vitrectomy, and primary IOL implantation with a minimum follow up (FU) of 3 months. Results Thirteen consecutive patients (all male) with a mean age of 42.8 years (range 17–82 years) underwent combined lensectomy, vitrectomy, and primary IOL implantation from February 2000 to January 2006. Postoperative FU ranged from 3 to 54 months (mean 17.6 months). Best corrected visual acuity (BCVA) at presentation ranged from 20/30 to hand movement and was worse than 20/200 in eight patients (61%). Four patients (31%) had blunt trauma with no globe rupture. Of the nine patients (69%) with a penetrating eye injury (PEI), eight had an intraocular foreign body (IOFB) with one retinal detachment at presentation. Four patients had primary closure at the time of the vitrectomy. All eight IOFBs were removed. Seven patients had additional scleral buckling and four intravitreal gas injection. BCVA at last FU ranged from 20/20 to 20/300 and was 20/40 or better in eight eyes (62%). All patients had an attached retina at last FU. One eye had further surgery for epiretinal membrane proliferation and ptosis. Conclusions These results suggest that combined vitrectomy, lensectomy and primary intraocular implantation can offer good visual rehabilitation in patients with traumatic cataract and posterior segment injury.

Prevalence of Linguatula serrata Nymphs in Mesenteric Lymph Nodes of Cattle and Buffaloes Slaughtered in Ahvaz Abattoir,Iran

Background

Linguatula serrata, one of the parasitic zoonoses, inhabits the canine respiratory system (final hosts). The objective of this study was to determine the prevalence rate of L. serrata nymphs in mesenteric lymph nodes (MLNs) of cattle and buffaloes (intermediate hosts) that were processed in the Ahvaz, Iran abattoir.

Methods

During November 2010 to March 2011, 223 animals (119 cattle and 104 buffaloes), in different sex and three age groups (<2, 2–< 3 and 3-> 3 years old) were sampled randomly at Ahvaz abattoir. Up to 35 grams of their mesenteric lymph nodes were examined separately for nymphal stages of L. serrata by digesting the samples with acid- pepsin method, collected the nymphs and counted under stereomicroscope.

Results

Overall 37(16.6%) of 223 animals were infected with L. serrata nymphs in their mesenteric lymph nodes. Prevalence of the infection in cattle and buffaloes were 16.8% and 16.3% respectively. The number of collected nymphs of MLNs was ranged from 1 to 16. No significant differences were seen in the infection rates between males and females (sexes) and age groups in the cattle and buffaloes (P <0.05).

Conclusion

Linguatula serrata has an active life cycle in the studied area and a zoonotic potential for transmission between animal and human. Avoiding use of raw MLNs to dogs can help reduce the infection.     

RELATIONSHIP BETWEEN SOME REPRODUCTIVE PARAMETERS AND BIOCHEMICAL PROPERTIES OF BLOOD SERUM IN RAMS

The objective of the present study was to describe the relationship between some reproductive parameters, hormonal levels, and some biochemical properties of blood serum in rams under the Afyon province conditions. The total protein and globulin were positively (P?<?0.01) correlated with sperm motility and sperm concentration in all of rams. Total lipid was negatively (P?<?0.05) correlated with sperm motility and concentration in Daglic, and it was positively (P?<?0.01) correlated with percentage of abnormal spermatozoa in Chios rams. Total lipid and cholesterol was positively (P?<?0.01) correlated with triiodothyronine in all of rams and was negatively (P?<?0.05) correlated with testosterone in Daglic rams. Percentage of abnormal spermatozoa were negatively (P?<?0.01) correlated with alanine amino transaminase (ALT) level, but were positively (P?<?0.01) associated with aspartate amino transaminase (AST) level and AST/ALT ratio in all of rams.     

Clinical evaluation of brushing time and plaque removal potential of two manual toothbrushes

Abstract: Aim: To compare plaque removal efficacy of Oral‐B CrossAction (CA) used for 1 min with an American Dental Association (ADA) manual toothbrush used for 2 or 5 min in an examiner‐blind, three‐treatment, six‐period crossover study. Materials and methods: After refraining from all oral hygiene procedures for 23–25 h, subjects were randomly assigned to one of nine possible six‐period (visit) treatment sequences. Plaque was assessed at baseline (Rustogi Modified Navy Plaque Index). Post‐brushing scores were recorded after brushing with a marketed dentifrice and the assigned toothbrush for the specified duration. The same procedure was followed at each of six subsequent visits. Clinical measurements were carried out by the same examiner. Results: Forty subjects completed the study. All three treatments effectively removed plaque from the whole mouth, along the gingival margin and from approximal surfaces. Whole mouth and gingival margin plaque removal scores with CA for 1 min did not differ significantly from scores with the ADA toothbrush used for 2 min. The ADA brush used for 5 min showed significantly greater whole mouth (P < 0.001) and gingival margin (P < 0.001) plaque reduction than the two other treatments. Approximal plaque removal scores did not differ between the three treatments. Conclusions: Efficient plaque removal can be achieved after 1 min of brushing with CA. The amount of plaque removed did not differ significantly from that achieved with the ADA brush after 2 min of brushing. Greater whole mouth and gingival margin plaque removal scores were seen with the ADA brush after 5 min.     

Acute pancreatitis secondary to oral contraceptive-induced hypertriglyceridemia: a case report

Abstract

Hypertriglyceridemia is the third most common cause of acute pancreatitis. Among the causes that lead to secondary hypertriglyceridemia, the use of contraceptive agents is the main reason to be assessed in young women. We report a case of a 31-year-old woman who had suffered two acute pancreatitis episodes secondary to hypertriglyceridemia. In the investigation, the previous medical team indicated a genetic screening before ruling out all secondary causes. LPL, apo CII and apo AV genes were negative for mutations. In the first appointment with us, the patient reported the use of a contraceptive agent for about 2?years. She was instructed to discontinue the drug. After one year of follow-up, her serum triglycerides are within the normal range and a copper intrauterine device was the method chosen by the patient for contraception.
