Ovarian Hyperstimulation Syndrome (OHSS) an iatrogenic and potentially life-threatening complication resulting from an exaggerated response to ovulation induction with gonadotropins during assisted reproductive technologies, is a self-limiting disorder with a broad spectrum of clinical manifestations related to increased capillary permeability and fluid retention brought about by many biochemical mediators especially vascular endothelium growth factor (VEGF), playing a pivotal role in its pathophysiology. Although various strategies had been proposed and tried to prevent this serious complication none was found to be completely effective. With the current knowledge and understanding of the causative molecule i.e. VEGF in the pathogenesis of OHSS, pharmacologic tools targeting this member of the family of heparin binding proteins, seems promising. Antagonizing and blocking VEGF action by dopamine agonists especially Cabergoline has shown to be a valid alternative to overcome the changes induced by the gonadotropins. Delaying embryo transfer with embryo cryopreservation definitely reduces the incidence of OHSS but not the early OHSS. In-vitro maturation of oocytes a major breakthrough in the field of ART although totally eliminates the risk of OHSS is highly labor intensive and cannot routinely carried in all cycles. Thus the newer drugs, mainly the dopamine agonists in the light of the new pathogenic and pharmacological evidence, should definitely be considered for prevention of both early and late OHSS. 相似文献

Background
The progressive decline in the CD4 count in HIV patients leads to a more general decline in immune functioning. The study has been carried out to determine the decline in CD4 count in HIV patients.Methods
The study was conducted in a medical college hospital at Maharashtra. The information on baseline CD4 count was gathered from positive patient records registered in the central disease registry. The baseline CD4 count was the first count of CD4 obtained when the patient is diagnosed as HIV positive and further two subsequent readings. The time from baseline (t1) till the last CD4 count (t2) was divided into the different quartiles and the median decline in CD4 count in each quartile was determined. As the time between the two CD4 count measurements was not uniform the rate of change in CD4 was measured with respect to time as [X (t2) − X (t1)/(t2 − t1)]. Correlation was assessed using correlation coefficient.Results
As the CD4 counts were following skewed distribution, the normality was achieved by cuberoot transformation. The overall rate of decline in CD4 count was estimated to be 35 cells/μL per year with 95% confidence interval (CI) as (17.01, 85.04). The correlation coefficient between decline in CD4 and the initial CD4 count in the four time quartiles was (r = −0.51; p = 0.001, r = −0.79; p = 0.000, r = −0.48; p = 0.015 and r = −0.80; p = 0.000) respectively. The median decline in the CD4 count in 0–6 months was 3 cells/μL, in (6–11) months was approximately 26 cells/μL, in (11–21.5) months was 30 cells/μL and in more than 21.5 months the median decline was 52 cells/μL.Conclusions
There was a progressive decline in the CD4 count following HIV infection. An understanding of the influence of decline in CD4 count in HIV patients not on ART is important for clinical management of HIV disease. 相似文献5.
Instability after rupture of anterior cruciate ligament (ACL) may lead to recurrent episodes of giving way, an increased risk of meniscal injury and premature degenerative changes. A total of 25 cases with ACL injuries were evaluated after reconstruction with bone patellar tendon bone graft through a mini-arthrotomy. All patients were male. Maximum number of patients were between 25-30 years of age (40%). The most common modality of injury was contact sports (44%). Most common complaint was instability of knee (100%). Average Lysholm score increased from pre-operative of 47 (27-75) to post-operative of 87 (68-95). Two patients (8%) had retropatellar pain. Moderate to severe graft site tenderness was present in 4 (21%). After an average follow up of one year three months, the results were comparable with the results of arthroscopic reconstruction.Key Words: Anterior cruciate ligament reconstruction, Mini arthrotomy 相似文献
