Is the outcome of in-vitro fertilization and embryo transfer treatment improved by spontaneous or surgical drainage of a hydrosalpinx?

A pilot study was designed to examine whether the outcome of embryo transfer in women with a hydrosalpinx might be improved by surgical drainage of the hydrosalpinx at the time of oocyte collection for in- vitro fertilization treatment. A comparative, controlled but retrospective analysis of the results was performed of all women with infective tubal damage aged <40 years old, who had ovulatory cycles, a normal uterus and a partner with normal spermatozoa. A standardized treatment regimen was used. A maximum of three embryos were transferred. Hydrosalpinx was defined by prior hysterosalpingography and/or laparoscopy with transcervical dye injection. A total of 237 embryo transfer cycles in women with hydrosalpinges (tubal distension not visible in 151, visible but not drained in 30 and drained in 56) were compared with 705 embryo transfer cycles in women with tubal disease but no hydrosalpinx. Results were analysed in the first three cycles but also separately in the first cycle to check for bias. Success rates were higher in the first cycle, but did not significantly influence overall differences. Implantation rates were significantly reduced overall in the hydrosalpinx group (8.0 versus 13.2% for controls; P < 0.001), being 8.3% (P < 0.01) in the subgroup without evident tubal distension and 7.5% (not significant) in the drained hydrosalpinx group. This study shows that tubal damage with distal occlusion is associated with a marked reduction in embryo implantation, even in the absence of obvious fluid distension. Surgical drainage of distended hydrosalpinges appears to offer no benefit.      

Factors Related to Drop-outs by Borderline Patients : Treatment Contract and Therapeutic Alliance

High patient drop-out rates have traditionally interfered with both treatment and study of patients with borderline personality disorder (BPD). The authors tested hypotheses that an adequate treatment contract, a positive therapeutic alliance, and the severity of illness would all correlate with continuation of treatment versus drop-out in a BPD cohort receiving psychodynamic psychotherapy. Therapists' contributions to the contract and to the alliance correlated with the length of treatment. Patients' impulsivity was negatively related to length of treatment. This study supports the view that the therapist's technique plays a role in engaging the borderline patient to remain in treatment.     

The continuity of personality in schizophrenia

Some schizophrenic patients claim that their personalities have been damaged or destroyed so that they bear little or no resemblance to their former selves. This assertion has several unfortunate consequences: patients believe that they no longer have access to skills they had acquired previously, and they believe that understanding their past has no relevance in trying to make sense of the present or in appreciating the source of their expectations for the future. This article provides clinical examples of the continuity of personality and considers why patients and some clinicians might hold opposite points of view on this issue.     

Predictors of dropout in psychodynamic psychotherapy of borderline personality disorder

This study aimed to identify patient factors that predict early dropout from psychodynamic psychotherapy for borderline personality disorder (BPD). Thirty-six BPD patients began an open-ended course of twice per week psychodynamic psychotherapy that was defined in a treatment manual and supervised. Dropout rates were 31% and 36% at 3 and 6 months of therapy, respectively. Survival analysis techniques demonstrated that age and hostility ratings predicted early dropout, with continuers more likely to be older and expressing lower levels of hostility than dropouts. Many variables hypothesized to predict dropout failed to do so. Both the positive and negative findings are discussed relative to the literature.     

A randomized efficacy trial of citicoline in patients with acute ischemic stroke

BACKGROUND AND PURPOSE: Citicoline (cytidine-5'-diphosphocholine; CDP-choline) may reduce central nervous system ischemic injury by stabilizing cell membranes and reducing free radical generation. A previous dose-comparison trial in patients with acute stroke found that 500 mg of citicoline appeared to improve neurological outcome with minimal side effects. METHODS: The current trial was a 33-center, randomized, double-blind, efficacy trial in 394 patients comparing placebo (n=127) with citicoline (n=267) (500 mg po daily) for 6 weeks, with a 6-week posttreatment follow-up period. Patients with acute (24 hours) ischemic strokes clinically assessed to be in the middle cerebral artery territory with National Institutes of Health Stroke Scale (NIHSS) > or = 5 were enrolled. RESULTS: Mean time to treatment was 12 hours, and mean age was 71 for placebo and 70 for citicoline. Although mean baseline NIHSS were similar for both groups, there was a higher percentage of placebo patients with NIHSS <8 (34% vs 22%; P<0.01). The incidence and type of side effects were similar between the groups. The planned primary analysis (logistic regression: 5 categories Barthel) failed the proportional odds assumption and was rendered unreliable. There were no between-group differences seen on the planned secondary assessment analyses at 90 days, including the Barthel Index > or = 95 at 12 weeks (last observation carried forward: placebo 40%; citicoline 40%) or mortality rate (placebo 18%; citicoline 17%). However, post hoc analyses in a subgroup of patients with baseline NIHSS > or = 8 found that citicoline-treated patients were more likely to have a full recovery (Barthel > or = 95): placebo 21%; citicoline 33%; P=0.05; whereas no difference was seen in patients with baseline NIHSS<8 (placebo 77%; citicoline 69%; P>0.1. CONCLUSIONS: The results of this study indicate that citicoline was safe but ineffective in improving the outcome of patients with acute ischemic stroke who were enrolled in this trial. Post hoc analyses indicate that there may be a subgroup of patients with moderate to severe strokes who would benefit.     

Penfluridol: An open phase III study in acute newly admitted hospitalized schizophrenic patients

An open study was carried out in 17 acutely ill, newly admitted, floridly psychotic schizophrenic patients to a city hospital in New York. Penfluridol was given on a daily basis up to doses of 120 mg and patients were rated objectively by means of different psychometric evaluations; vital signs were monitored daily as were side effects.The drug was found to be a rapid acting, well-tolerated, and highly effective antipsychotic agent within the population of patients explored and within the dose range used. It was particularly effective in acutely agitated floridly paranoid schizophrenics; a statistically significant impact was achieved by 7 days and usually within 72 h after initiating treatment. The drug appears unique in that (1) its effects are realized without the untoward and usually trouble-some effects of nonspecific sedation attendant upon the use of many other neuroleptic medications, and (2) even within the relatively high doses used it produces no hypotensive effects. It is concluded that this appears to be a unique antipsychotic agent and a potentially important addition to the treatment armamentarium of both acute and chronic schizophrenic individuals.Dr. Klein was a research fellow who has since returned to the University of Munich, West Germany. Dr. Selzer was also a research fellow who is now in private practice     

Screening for complement deficiency in bacterial meningitis

Seventy-seven children with bacterial meningitis were screened for complement deficiency. Both the classical and the alternate pathways were normal in 75 patients. Transiently reduced total haemolytic activity of the classical pathway was documented in a boy with meningococcal meningitis. Total haemolytic activity of both the classical and the alternate pathways were reduced in another patient with pneumococcal meningitis: individual complement components determination indicated predominant activation of the alternate pathway.     

Identification of differentially expressed genes in aflatoxin B1- treated cultured primary rat hepatocytes and Fischer 344 rats

Aflatoxin B1 (AFB1), a mutagen and hepatocarcinogen in rats and humans, is a contaminant of the human food supply, particularly in parts of Africa and Asia. AFB1-induced changes in gene expression may play a part in the development of the toxic, immunosuppressive and carcinogenic properties of this fungal metabolite. An understanding of the-role of AFB1 in modulating gene regulation should provide insight regarding mechanisms of AFB1-induced carcinogenesis. We used three PCR- based subtractive techniques to identify AFB1-responsive genes in cultured primary rat hepatocyte RNA: differential display PCR (DD-PCR), representational difference analysis (RDA) and suppression subtractive hybridization (SSH). Each of the three techniques identified AFB1- responsive genes, although no individual cDNA was isolated by more than one technique. Nine cDNAs isolated using DD-PCR, RDA or SSH were found to represent eight genes that are differentially expressed as a result of AFB1 exposure. Genes whose mRNA levels were increased in cultured primary rat hepatocytes after AFB1 treatment were corticosteroid binding globulin (CBG), cytochrome P450 4F1 (CYP4F1), alpha-2 microglobulin, C4b-binding protein (C4BP), serum amyloid A-2 and glutathione S-transferase Yb2 (GST). Transferrin and a small CYP3A-like cDNA had reduced mRNA levels after AFB1 exposure. Full-length CYP3A mRNA levels were increased. When liver RNA from AFB1-treated male F344 rats was evaluated for transferrin, CBG, GST, CYP3A and CYP4F1 expression, a decrease in transferrin mRNA and an increase in CBG, GST, CYP3A and CYP4F1 mRNA levels was also seen. Analysis of the potential function of these genes in maintaining cellular homeostasis suggests that their differential expression could contribute to the toxicity associated with AFB1 exposure.
